SNOW TRACK BELT FOR MOTORCYCLE
ABSTRACT OF THE DISCLOSURE:
An endless traction belt and a method for its manufacture are provided. The traction belt has a main body made primarily of elastomeric material, and is adapted to be moved in an endless path having a longitudinal axis. The main body comprises a sub-stantially smooth inner surface, and a ground engag-ing outer surface having a plurality of traction-increasing portions or teeth. The teeth also act as sprocket engaging means for driving the belt.
Description
This invention relates to an endless flat-type traction belt for a ski attachment for motorcycles, and in particular to a fla~-type traction belt on which the traction means also serves as a sprocket enraging means for driving said belt.
The primary object of the present invention is to provide a traction belt which can be used on a ski attac~nent for motorcycles, similar to that described by pharisee in U.S. Patent 3,885,641. The ski attach-mint, for which the belt of the present invention maybe used, comprises skis what are adapted to be con-leniently attached to a motorcycle to support it for movement over snow surfaces. Inn used as a ski at-tachment, the attachment comprises two main parts:
a single ski, which is attached to the front wheel of the motorcycle, which permits the front wheel, while stationary, to slide over the snow; and a driving device, for connection to the rear wheel of the motor-cycle, which may comprise two skis on either side of the device for balance, and an endless traction belt for providing driving contact with the terrain. The driving device utilizes the driving, or rear wheel of the motorcycle to provide the driving force for the attachment. The belt of the present invention pro-vises traction, and utilizes the driving force of the motorcycle to drive the ski attachment OR; I, .. I ,, In like ski attaclument twilight by Hclrris, propel-soon of the motorcycle is provided by contacting the drive wheel of tile motorcycle with two sprockets which tangentially contact a driving chain attached to the traction belt. This can be seen in FIG. in the }Harris patent. When sprocket 44 contacts the chain 50 directly over roller I this configuration, be-cause of the small surface area owe contact, and be-cause of the extreme pressures applied on the points of contact, causes the driving chain to wear out quickly. Also, because of the small area of contact between the sprocket and the belt, a certain amount of slippage in the drive system is possible.
The belt construction used by Harris, where a driving chain is attached to the belt, is expensive in terms of materials and labor needed to provide such construction also, such construction has the disk advantage that separation of the driving chain from the belt can and does occur A n~nber of belt driving systems are known in the art, none of which are suitable for application to a motorcycle ski adapter kit.
Chaumont, U.S. Patent 3,887,243, relates to an endless wrack that is adapted to be used on motor driven vehicles such as tractors, snowmobiles, etch In the belt described by Chaumont, the sprockets or ~%~
driving the belt art located on the inside of the track and -intake driving contact lath the top of tile belt Since the traction part OX tile belt is the bottom ox toe belt, the driving portion of the belt in Chaumont is separated prom the traction portion of the belt.
'reed lander, U.S. Patent 1,82~,136, teaches a pulley and a belt having matched teeth used as a drive in force. In the pulley and belts taught by Freed-lander, the driving force is applied to the insider the top of the belt Freed lander, U.S. Patent 1,611,829, teaches a driving belt, designed particularly as a fan belt for use in automobiles. The belt taught by Freed lander has a central member composed of rubberized cord fabric cut straight or parallel to the reinforcement cords and in a restretched condition. The tension member of the belt comprises a rubberized fabric cut on the bias, or a an angle, and in a restretched 2Q condition. Accordingly, the belt in nonstretchable Hallaman, U.S. Patent 3;493,684, teaches a tree-lion belt having lugs on its outer surface and tension cords, made of in extensible but flexible wire cord, embedded in the belt 9 to provide increased transverse stiffness. Longitudinal tension-resisting members lo are positioned centrally through the thicicness of the belt in a closely spaced parallel relationship.
I
Chaumont, U.S. Patent 3,SS3,191, teaches an end-less track which has a main body, made primarily of an elastorneric material, which is adapted to be moved in an endless petit having a longitudinal axis The main body comprises an inside surface and a ground engaging surface. The inside surface at is provided with pro-sections 17 which are adapted to be engaged by a co-operating pair of inside drive sprockets.
It is recognized in the art to provide a toothed power transmission belt wherein the teeth have a cross-sectional configuration of generally trapezoidal form with a radius between the shorter base of the tripe-void and the angled face, wherein the space between the teeth is at least equal to the major base of the trapezoid, and the teeth are for mating with con-jugating pulley teeth.
It is also known in the art to provide a toothed power transmission belt wherein the teeth have a cross-sectional configuration composed of two circular intersecting arcs for meshing with mating conjugate curvilinear pulley teeth; or example, see U.S.
Patent 3,756,091 issued to Miller.
It is also known in the art to provide a toothed power transmission system wherein the dimensional relationship of the belt teeth and the grooves and the pulley teeth and Grooves is such that in the longitudinal extent of the belt between the pulleys, the height of the belt teeth is greater than tulle depth of the pulley grooves, while as the Yell travels around tile pulleys, the extrerlcly outwardly facing port lions of tile belt teeth t~;liCl~ confront tile pulleys come into contact with the portions of the toothed pulley disposed between the pulley Titan which define the bottoms of the pulley grooves; for example, see USE Patent 4,037,485 to Lubbock. In this case, the meshing or the belt teeth is not of the conju~atè
10 form.
The above mentiorled art specifically teaches that the toothed pudgier transmission belts are constructed on a precisely defined right circular cylinder, wherein the mutually cooperating neutral axis plane is stab-fished by said right circular cylinder. The toothed power transmission belts of the prior art are primary-lye intended to be used for power transmission from one toothed pulley to another toothed pulley.
Accordingly, a need exists in the art for a special flat-type traction belt with a dual-purpose toothed surface and capable of being driven by toothed sprockets and also of providing vehicular propulsion In particular, a need exists for a special flat-type traction belt with a dual purpose toothed surface capable of being driven by toothed sprockets, and for use with an adapter kit that is used to covert a JO
motorcycle from a street or highway machine to a multi-terrain, all-weather machine with an em~Llasis on snow transportation.
Accordingly, it is an object of this invention to provide a special atop traction belt with a dual purpose toothed surface capable of being driven by two toothed sprockets, and also capable of pro-voiding traction for vehicular propulsion for multi-terrain.
further object of this invention is to provide a flat-type traction belt as described above for use with a quick adapter kit that converts a motorcycle prom a street or highway machine to a multi-terrain all-weather machine, with emphasis on snow transport station.
A further object of this invention is to pro-vise a special flat-type traction belt which is high-lye abrasion-resistant, and has a high tear strength.
A further object of this invention is to pro-vise a flat-type traction belt which is relatively light in weight yet demonstrates treat strength and flexibility.
A further object of this invention is to pro-vise a traction belt as described which is inexpensive to build.
Further objects of this invention will become apparent from the following specification and claims.

LYLE DESCi.~IPTIOil OF THE Pi 'EI'P~ï IBO:l)Ii~NTS
FIG. 1 illustrates a ski attac~lent attached to a motorcycle. The front wheel 12 of the motorcycle 10 is fixedly attached to ski 14. Rear wheel 22 of the motorcycle 10 provides the driving force for the ski attachment. The driving force of tune rear wheel 22 is transferred via two toothed metal hubs 20, and via plastic sprockets 24, to the traction belt I When used on terrain other than snow, tune adapter kit will be used without the ski, FIG. 2 is a rear view looking forlJard of the rear motorcycle wheel 22, which is making contact with a toothed metal hub wheel 20 ox the ski adapter kit. The toothed metal hub wheel 20 does not contact the traction belt 18, but is connected to plastic sprockets 24 on either side of the hub isle 20; the plastic spark-eta 24 engage the traction belt 18.
EGO, 3 is a side view of the rear jowl 22 of the motorcycle, and shows the wheel malt g contact with the driving portion in the ski adapter kit. For con-lenience, tune same numbers will be used throughout the drawings to define the different illustrations of the same features of the invention.
In FIG. 3, the cycle wheel 22 makes contact with the forward toothed metal hub wheel and sprockets 23, and with the at metal hub wheel and sprockets aye, which in turn make contact with the traction belt 180 The elements 23 arid aye are a general representation of the elements 20 and 24 in FIGS. 1 and 2. EGO. 3 also illustrates the endless belt path of the traction belt.
During its driving operation, the cycle wheel 22 will be moving in a clockwise direction The toothed metal hub and sprockets 23 will move in a countercloclcwise direction, which in turn will propel the traction belt in a clockwise direction over the three 2-inch pulleys 25, around the flat pulley 27, and over the large aft pulley 29.
FIG 4 is an elevated, side angle view of a cut-away portion of the traction belt of the invention, which belt is noted generally as 18. A plurality of reinforcing members 32 are embedded in the main body of the traction belt, and extend parallel to the longitudinal axis, Tile two layers of base ply 34 can be seen from both the front end the side of the cut-away portion of the belt, The tractlon-increasing port lion or teeth 36 provide traction contact with the groomed, a jell as tooth-engaging means with the driving spark-eta. Surface 38 is substantially smooth so as to roll easily over the pulleys of the adapter.
FIG. 5 is a side angle view of the traction belt I and further illustrates the reinforcing cord 32, the base plies 34, the teeth 36, and the top surface 38. The teeth 36 will generally have a depth 42 which will represent 60-75 percent of the total belt thick-news 40.
FIG, 6 is a front view cross section of the tree-lion belt OWE In this figure, the reinforcing members or cords 32 are illustrated as being single, index pendant elements which are perpendicular to the plane of the drawing, For suitable flexibility and strength it has been found that it is preferred to have 18-22 reinforcing members per inch of belt As can be seen from the drawings, the toothed metal hub wheel 20 never makes contact with the tract lion belt 18, Referring to Fig 3, the toothed metal Hubbell 20 is fixedly attached to plastic sprockets I which have teeth 21 which generally match the traction-increasing portion or teeth 36 of the traction belt Referring to Fig 2, the rear cycle wheel makes I
contact with the metal hub wheel 20, generally in the middle portion of the driving device. The plastic sprockets 24 are disposed at either end of the metal hub wheel 20 and make contact with the traction belt 18 at the edges thereof.
It is preferred that tune traction portions or teeth of the belt be large because of the inherent flexibility of the elastomers This is preferred since the teeth of the belt engage the teeth ox the plastic sprockets to provide the driving force of the belt, and the driving force of the sprockets would be disk sipated if the teeth of the belt are too flexible.
Those skilled in the art will be able to determine optimum teeth sizes for a specific use using methods well known in the art. For the purposes of the present invention, it is preferred that the width of the teeth, as measured at the midpoint thereon, represent about 5/12 to 1/2 the pitch; the traction belt will have about 6 teeth for each 3-1/2 inch longitudinal port lion of the belt.
More particularly, the belt of the invention, fonts use with a motorcycle adapter kit, has the teeth 36 and the grooves 37 there between composed of a single radius 39 at the bottom of the tooth 36, and another single radius 41 at the top of the groove, such that the width of the tooth 36 at the center of the tensile member 32 is not treater than the width of the groove 37 at the center of the tensile member. The depth 42 of the tooth 36 is substantially greater than radius 39; in particular, the radius MY is generally less titan 50 percent of the depth 42 of the tooth 36.
Specifically, the radius 39 of the tooth 36 is approxi-mutely 7/64 inches, and the radius 41 of the groove 37 is approximately 5/32 inches, while the pitch of the teeth 36 is approximately .630 inches, and the depth 42 of the teeth 36 is approximately .320 inches.
The metal hub wheel and sprockets 23 is provided with teeth 21 which engage the grooves 37 of the belt of the present invention. The grooves between the teeth 21 of the metal hub wheel and sprockets 23 are of sufficient depth that the radius 39 of the teeth 36 does not engage the bottom of the grooves between the teeth 21 of the pulley 23.
Although the belt of the present invention lung-lions, to a large extent, as a synchronous belt, one of the advantages of the present invention is that the precise tolerances of a synchronous belt are not no-squired buckles of the flexibility of the traction belt as made herein. Accordingly, the great expense en-countered in producing a synchronous belt, because, for example, a synchronous belt needs to be formed on a precision tooled metal drum, are avoided In particular, the teeth 21 of the metal hub wheel and sprockets 23 were not generated as a conjugate form, but were produced by projecting the form of the tooth 36 onto the pulley 23 when the belt 18 is bent around a radius of 2.5 inches at the top ox the grooves 37 of the belt 18. Therefore, it must be appreciated that as the teeth 36 of the belt 18 contact the ground in order to provide inactive motion thereto, the teeth 36 will become worn at the bottom of the tooth 36, and the tooth engagement must rely solely upon engageinent of the teeth 21 of the metal hub wheel and sprockets 23 in the grooves 37 of the belt 18.
I metal hub wheel is preferred since metals are generally lon~-wearing materials. It will be recognized by those skilled in the art that other long-wearing materials may be used.
The sprockets 24 may be made of any long-wearing materials. Plastic sprockets are preferred since the materials are relatively inexpensive, and the expense and labor of machining and precision tooling the sprockets is avoided.
As can be seen in Fig 3, the specific configu-ration of the traction belt on the rollers mazes possible a large contact area between the sprockets and the traction belt. Thus by using oversized aft roller 29 and flat roller 27, an arc of approximately S0 to 110 of contact with the aft metal hub wheel and sprockets aye is possible. By using the three ' two inch rollers in conjunction with the flat roller, an arc of approximately 100 to 160 of contact with the furrowed metal hub wheel and sprockets 23 is possible. Since there is a large area of contact be-tweet the driving sprockets and the traction belt, the driving force is distributed over a large area; this correspondingly reduces the amount of wear on the sprockets and the traction belt. Also, because of the large contact area there is less chance for slippage.
Any suitable elastomeric material can be used for the main body of the belt. By any suitable material, it is meant that the elastomeric material will be Abe ration resistant, and will det.nonstrate a high tear strength. Preferably, tile main body of the belt will be made from an abrasion resistant, high tear strength rubber stifle.
Stucco refers to a rubber composition commonly used in the driving belt art in which discrete minute fibers are incorporated within the rubber stoical to stiffen the rubber The use of stifle is illustrated in, for example, U.S. patents 1,611,830, 1,700,999 and 3,416,383. In general, the minute fibers are oriented perpendicular to the longitudinal axis, or transversely, in the belt. In particular, the stifle used in the present invention may contain from 5-50 phi of fibers.
Examples of the elastomers used for the main body of the belt are neoprene styrenes butadiene rubber, natural rubber, polyurethane, and polybutad~ne rubber.
The preferred elastomers is neoprene.
Those skilled in the art will recognize that since polyurethane is handled differently from tile other elastomers nlentioned, that a belt made of polyp urethane will not be made by the method described herein. However, other conventional methods for building belts, Nemo in the art, may be employed using polyurethane.

The driving force of tune rear wheel 22 is transferred via two toothed metal hubs 20, and via plastic sprockets 24, to the traction belt I When used on terrain other than snow, tune adapter kit will be used without the ski, FIG. 2 is a rear view looking forlJard of the rear motorcycle wheel 22, which is making contact with a toothed metal hub wheel 20 ox the ski adapter kit. The toothed metal hub wheel 20 does not contact the traction belt 18, but is connected to plastic sprockets 24 on either side of the hub isle 20; the plastic spark-eta 24 engage the traction belt 18.
EGO, 3 is a side view of the rear jowl 22 of the motorcycle, and shows the wheel malt g contact with the driving portion in the ski adapter kit. For con-lenience, tune same numbers will be used throughout the drawings to define the different illustrations of the same features of the invention.
In FIG. 3, the cycle wheel 22 makes contact with the forward toothed metal hub wheel and sprockets 23, and with the at metal hub wheel and sprockets aye, which in turn make contact with the traction belt 180 The elements 23 arid aye are a general representation of the elements 20 and 24 in FIGS. 1 and 2. EGO. 3 also illustrates the endless belt path of the traction belt.
During its driving operation, the cycle wheel 22 will be moving in a clockwise direction The toothed metal hub and sprockets 23 will move in a countercloclcwise direction, which in turn will propel the traction belt in a clockwise direction over the three 2-inch pulleys 25, around the flat pulley 27, and over the large aft pulley 29.
FIG 4 is an elevated, side angle view of a cut-away portion of the traction belt of the invention, which belt is noted generally as 18. A plurality of reinforcing members 32 are embedded in the main body of the traction belt, and extend parallel to the longitudinal axis, Tile two layers of base ply 34 can be seen from both the front end the side of the cut-away portion of the belt, The tractlon-increasing port lion or teeth 36 provide traction contact with the groomed, a jell as tooth-engaging means with the driving spark-eta. Surface 38 is substantially smooth so as to roll easily over the pulleys of the adapter.
FIG. 5 is a side angle view of the traction belt I and further illustrates the reinforcing cord 32, the base plies 34, the teeth 36, and the top surface 38. The teeth 36 will generally have a depth 42 which will represent 60-75 percent of the total belt thick-news 40.
FIG, 6 is a front view cross section of the tree-lion belt OWE In this figure, the reinforcing members or cords 32 are illustrated as being single, index pendant elements which are perpendicular to the plane of the drawing, For suitable flexibility and strength it has been found that it is preferred to have 18-22 reinforcing members per inch of belt As can be seen from the drawings, the toothed metal hub wheel 20 never makes contact with the tract lion belt 18, Referring to Fig 3, the toothed metal Hubbell 20 is fixedly attached to plastic sprockets I which have teeth 21 which generally match the traction-increasing portion or teeth 36 of the traction belt Referring to Fig 2, the rear cycle wheel makes I
contact with the metal hub wheel 20, generally in the middle portion of the driving device. The plastic sprockets 24 are disposed at either end of the metal hub wheel 20 and make contact with the traction belt 18 at the edges thereof.
It is preferred that tune traction portions or teeth of the belt be large because of the inherent flexibility of the elastomers This is preferred since the teeth of the belt engage the teeth ox the plastic sprockets to provide the driving force of the belt, and the driving force of the sprockets would be disk sipated if the teeth of the belt are too flexible.
Those skilled in the art will be able to determine optimum teeth sizes for a specific use using methods well known in the art. For the purposes of the present invention, it is preferred that the width of the teeth, as measured at the midpoint thereon, represent about 5/12 to 1/2 the pitch; the traction belt will have about 6 teeth for each 3-1/2 inch longitudinal port lion of the belt.
More particularly, the belt of the invention, fonts use with a motorcycle adapter kit, has the teeth 36 and the grooves 37 there between composed of a single radius 39 at the bottom of the tooth 36, and another single radius 41 at the top of the groove, such that the width of the tooth 36 at the center of the tensile member 32 is not treater than the width of the groove 37 at the center of the tensile member. The depth 42 of the tooth 36 is substantially greater than radius 39; in particular, the radius MY is generally less titan 50 percent of the depth 42 of the tooth 36.
Specifically, the radius 39 of the tooth 36 is approxi-mutely 7/64 inches, and the radius 41 of the groove 37 is approximately 5/32 inches, while the pitch of the teeth 36 is approximately .630 inches, and the depth 42 of the teeth 36 is approximately .320 inches.
The metal hub wheel and sprockets 23 is provided with teeth 21 which engage the grooves 37 of the belt of the present invention. The grooves between the teeth 21 of the metal hub wheel and sprockets 23 are of sufficient depth that the radius 39 of the teeth 36 does not engage the bottom of the grooves between the teeth 21 of the pulley 23.
Although the belt of the present invention lung-lions, to a large extent, as a synchronous belt, one of the advantages of the present invention is that the precise tolerances of a synchronous belt are not no-squired buckles of the flexibility of the traction belt as made herein. Accordingly, the great expense en-countered in producing a synchronous belt, because, for example, a synchronous belt needs to be formed on a precision tooled metal drum, are avoided In particular, the teeth 21 of the metal hub wheel and sprockets 23 were not generated as a conjugate form, but were produced by projecting the form of the tooth 36 onto the pulley 23 when the belt 18 is bent around a radius of 2.5 inches at the top ox the grooves 37 of the belt 18. Therefore, it must be appreciated that as the teeth 36 of the belt 18 contact the ground in order to provide inactive motion thereto, the teeth 36 will become worn at the bottom of the tooth 36, and the tooth engagement must rely solely upon engageinent of the teeth 21 of the metal hub wheel and sprockets 23 in the grooves 37 of the belt 18.
I metal hub wheel is preferred since metals are generally lon~-wearing materials. It will be recognized by those skilled in the art that other long-wearing materials may be used.
The sprockets 24 may be made of any long-wearing materials. Plastic sprockets are preferred since the materials are relatively inexpensive, and the expense and labor of machining and precision tooling the sprockets is avoided.
As can be seen in Fig 3, the specific configu-ration of the traction belt on the rollers mazes possible a large contact area between the sprockets and the traction belt. Thus by using oversized aft roller 29 and flat roller 27, an arc of approximately S0 to 110 of contact with the aft metal hub wheel and sprockets aye is possible. By using the three ' two inch rollers in conjunction with the flat roller, an arc of approximately 100 to 160 of contact with the furrowed metal hub wheel and sprockets 23 is possible. Since there is a large area of contact be-tweet the driving sprockets and the traction belt, the driving force is distributed over a large area; this correspondingly reduces the amount of wear on the sprockets and the traction belt. Also, because of the large contact area there is less chance for slippage.
Any suitable elastomeric material can be used for the main body of the belt. By any suitable material, it is meant that the elastomeric material will be Abe ration resistant, and will det.nonstrate a high tear strength. Preferably, tile main body of the belt will be made from an abrasion resistant, high tear strength rubber stifle.
Stucco refers to a rubber composition commonly used in the driving belt art in which discrete minute fibers are incorporated within the rubber stoical to stiffen the rubber The use of stifle is illustrated in, for example, U.S. patents 1,611,830, 1,700,999 and 3,416,383. In general, the minute fibers are oriented perpendicular to the longitudinal axis, or transversely, in the belt. In particular, the stifle used in the present invention may contain from 5-50 phi of fibers.
Examples of the elastomers used for the main body of the belt are neoprene styrenes butadiene rubber, natural rubber, polyurethane, and polybutad~ne rubber.
The preferred elastomers is neoprene.
Those skilled in the art will recognize that since polyurethane is handled differently from tile other elastomers nlentioned, that a belt made of polyp urethane will not be made by the method described herein. However, other conventional methods for building belts, Nemo in the art, may be employed using polyurethane.
cause the belt is required to turn over three
2-inch rollers in the driving system, a high degree of flexibility is needed. Accordingly, it has been found that to achieve this flexibility without sac-roughhousing traction, a belt which has substantial traction-increasing portions which are also used as teeth to engage driving sprockets, and which has a top that is relatively thin with respect to the total thickness or the belt, must be used. Accordingly, the top or inner surface of the belt of the invention represents from 25-40 percent of the total belt thick-news. It as been found that a belt thickness offbeat 0.480 inches with a tooth depth of about Queue inches is preferable. Thus, the flexible surface of the belt will have a thickness of about OKAY inches.
Preferably, the traction belt of the invention will have sufficient flexibility to bend with an arc of about 170 over a 2-inch roller. In most cases, however, the belt will have sufficient flexibility if it can bend over a 120 to 150 arc of a two inch roller. It is Yost preferred that the traction belt have substantially more flexibility than is minimally required to operate on the required belt path of the adapter kit Also, since tune traction-increasing portion or teeth of the belt are adapted to enrage the teeth of the driving sprockets, it is required that the teeth on the traction belt have a substantially uniform tooth pitch so that smooth engagement with the driving sprockets can be made.
In its operation, depending on the size of the motorcycle and the ski adapter kit used the belt of the present invention will provide about 98 to 200 so.
inches of track area contact with the terrain. In general, the belt will have a width ox about 5-9 inches, preferably 6-7 inches, and a length or air-cumference of about 60-120 inches, preferably 60-100 inches.
As a design option, the traction belt may be pro-voided with holes adapted to facilitate smooth disk charge of foreign materials such as snow.
Also, as a design option, additional traction patterns may be provided. For example, longitudinal cuts may be provided in the transverse traction port lions, or longitudinal ridges may be provided to help prevent sideways slide or "fishtailing".
The reinforcing members or cords nay be made of any material having sufficient flexibility and strength and compatibility with the elastomeric material used.
examples of such material used for the cord are polyp ester, armed, glass fiber, rayon, steel cord, or steel and fiber cord. The preferred material used in the cord is polyester.
The base ply may ye formed from any suitable fabric material which has sufficient flexibility and lo strength for the purpose used, as well as compatibility with the elastomeric material used. Examples of materials used in the fabric layer are nylon, polyp ester, cotton armed, and mixtures thereof. The pro-furred fabrics used in the ply are a polyester-cotton blend.
The method of construction of the belt 18 is similar to the assignee's issued patent 3,464,875, which is incorporated herein by this reference thereto.
The principal difference in construction of the belt 18 as opposed to the herein referenced patent is that the belt 18 is not intended fox side driving forces, and thrower is made thinner in overall height 40;
therefore, the depth 42 of the teeth 36 as a ratio; to the overall thickness 40 is somewhat reduced In particular, this ratio- of the present invention should be substantially 2/3. Thus, the belt of the ` present invention is made by applying layers of rubber, to the desired thickness, to a no~lo~l drum having a grooved bottle rubber matrix on the outside surface thereof. The rubber matrix has the desired shape for the traction portions. The reinforcing cord is heft-gaily and tightly wound around the first rubber layers, compressing the rubber into the grooved matrix to phony the shape of the traction portions.
When polyester cord is used, the cord will con-tract when curing temperatures are applied, compressing the rubber into the matrix even further.
The fabric plies are then applied over the rein-forcing cord.
The drum with the belt construction is then placed in a heating pot and subjected to a differential steam pressure cure. The outside of the drum will be main-twined under about 8-11 atmospheres pressure, while the center of the drum will be maintained at about 4-7 atmospheres. Cure time is between 1/2 to 1-1/2 hours.
The belt construction is then cooled, removed from the 2Q matrix, and inverted to put the teeth on the outside of the belt.
The length of the belt 18 is sufficiently long to permit the belt 18 to be turned upon itself to provide the teeth 36 on the exterior of the belt 18. Of course, it will be apparent to those skilled in the art to provide a belt 18 which was manufactured in its up-right position upon a flat drum with the teeth 36 provided upon the exterior of the belt lo by the me-trod of providing a top coy belt disclosed in the assignee's previously issued patent 4,106,966, which is hereby incorporated herein.
s will be apparent to those skilled in the art, the above description and examples are merely thus-trative of the present invention. Other parameters and permutation of the invention may be used without departing from toe inventive concept herein.
