CHAPLET-FORMING MACHINE.

Application filed March 25, 1925. Serial No. 18,182.

maintaining the proper distance between parts of a mold in which a casting is to be made. The invention is especially designed for use on chaplets well known in the art, made of perforated metal which are bent into more or less rectangular form and frequently provided with an integral member separating the two longest sides of the rectangle at approximately the middle of the chaplet.

The principal object of the invention is to construct a machine for this work in which the use of the ordinary expensive dies is dispensed with, in which chaplets of different desired sizes can be readily formed on one and the same machine b merely substituting a different horn or block around which the chaplet formed by the machine, and changing one or two other minor parts which can be much more easily accomplished than in the case of machines of the prior art.

The invention consists in a machine capable of attaining the foregoing and other objects hereafter set forth; which can be comparatively easily and cheaply made; which is very highly efficient in operation and is not readily liable to get out of order.

More particularly the invention consists in numerous features and details of construction which will be hereafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals designate the same parts throughout the several views:

Figures 11, 12, 13 and 14 are detail views of essential operating parts, taken at lines 11, 12, 13 and 14 of Figure 5, showing the first, second, third and fourth steps in the formation of the chaplet, Figure 10 showing the fifth step. Y

The mechanism of this invention is carried within a suitable supporting frame which may vary materially in shape without departing from this invention. The particular frame here used consists of two parallel, side frame members 16 and18, united at one end by the plate 20 detachably secured in place by any suitable means as, for instance, bolts 22 and spaced apart near the middle of the machine by a partition 24 entered by bolts or screws 26 passing through the side frame members. The frame parts heretofore described are sustained on conventional legs 28 rising from the floor or other suitable support.

Suitably journaled in the frame is a transverse, main driving shaft 30 equipped at one end with the conventional pulley or the like to which power from an outside source, not entering into this invention, is applied in any suitable conventional manner.

Rigid upon drive shaft 30 in proximity to the longitudinal middle of the machine is a miter beveled gear 34 meshing with beveled gear 36 on the end of a shaft. 38 at right angles to shaft 30. Shaft 38 is conventionally journaled in a bearing 40 formed in partition 24 and in a bearing 42 formed on the loweredge of plate 20. i

A very important part of the machine is the feed bar mechanism shown in perspective in Figure 9, the same consisting of a long bar 44 and a shorter bar 46, parallel thereto, the two being rigidly secured together in a movable carrier block 48. The two bars 44 and 46 are equipped with work feeding teeth 50, those on the two bars be,

I the frame.

ing opposite to each other so that a work blank 52 lying across them will be at right angles to the longitudinal planes of the bars.

Bars 44 and 46 are, as shown and described, spaced apart a substantial distance so that they can be located on opposite sides of a work supporting table 54 stationarily secured in place on the upper end of partition 24 by any suitable means, as, for instance, the screw 56. The fit of the parts is such that, as hereafter described, the work bars 44 and 46 may be moved vertically downwardpast the sides of this table 54 to a point where the top edges of the teeth 50 are below the upper surface of the table, this so that the work bars may be reciprocated under work blanks 52 resting on the table a sufficient distance so that the teeth will feed the work blanks along the table in a ratchetlike motion.

The carrier block 48 is mounted for the foregoing purpose below table 54, as clearly shown in Figure 5. The block 48 is, itself, horizontally reciprocal along the upper shelf of a right angle bracket 58 whose vertical .arm 58" is ver ically reciprocal in guides 60,

formed on one side of partition wall 24. Vertical motion is iven to this bracket in these guides through an eccentric cam 62 on shaft 38 coiitacting a roller 64 journaled in a laterally extending arm 06 on the lower end of bracket 58. The weight of the bracket and associated parts is sufficient to hold roller ('34 in engagement with cam 62 in all positions of the parts. Horizontal motion along the top of bracket 58 is imparted to work carrier block 48 through the agency of a connecting rod 08, pivotally connected to a lever 70 keved to a shaft 72 journaled in ne end of this shaft 72 carries a crank 74 operatively connected through a conventional. adjustment mechanism 76 with an eccentric 78 on main shaft 30. The two eccentrics 78 and 02 are so designed and adjiisted that as the two main shafts 30 and 38 rotate, the work holder block 48 is given the desired ratchetmotion described to carry work blanks 52 placed upon the table 54 from left to right through the machine, as viewed in Figure 5, between the successive )ositions shown upon the work blank in l igure 9.

One method of applying work blanks 52 is to have them cut outside the machine to the size shown in Fi ure 9, and manually apply them one at a time at the left hand end of the feeding device of Figure 9. The

machine of the drawings, however, contemplates feeding a continuous sheet of workable material 80 into the machine from the top, as shown in Figure 5, severing itin the machine into separate work blanks, and dropping such blanks one at a time into place on the work carrier. One method of accomplishing this result shown in the drawings comprises a stationary shear member 82 and a horizontally reoipibcal shear member 84, operatively associated together to sever portions of workable material at the juncture of these shear members and drop the severed pieces into a carrier 86 which deposits the sheared piece of workable material on the table 54 in reach of the feeding bars 44-46. In detail, the movable shear 84 is rigidl secured in a horizontally reciprocal crossread 88 connected at its opposite ends by )arallel links 90 to a yoke 02 pivoted on sleeves, not shown, surrounding shaft 94 hereafter referred to. Pivotally connected to a lug 96 on this yoke 92 is a parallel bar connecting rod 98 pivoted atits lower end to a short arin 100 of a bell crank journaled on shaft 7 2, the longer arm 102 of the bell ci'aiik carryin a roller 104 held against a cam 106 on shaft 30 by any conventional spring mechanism not shown. The parts just "escribed are so shaped and proportioned that movable shear blade 84 is reciprocated across stationary blade 82 at the proper time to sever work blanks from workable material 80 as they are required by the work carrier mechanism 44-46 in the pro er operation of the machine.

The carrier member 86 heretofore referred to is rigidly mounted upon shaft 94. Rigid oii' shaft 94 is a crank 108 ivotally engaging a connecting rod 110 attac 18d at its 0 posite end to the upper end of a, lever 112 oosely journaled at its middle on shaft 72, the lower end of this lever carrying a cam roller 114 travelim in the groove track 110 of a cam wheel 1T8 on shaft 30. he upper edge of carrier 86 in the position shown in Figure 5 is provided with a work blank holding notch 120 ada ited to, as shown, receive blanks severed rom material 80. The depth of this notch 120 may be varied by an adjusting screw 122 to accommodate blanks of different sizes to be treated by the machine. The cam track 116 is so shaped that on a complete revolution of shaft- 30, carrier 80 will be rocked from the position of Figure 5 in a clockwise direction sufficiently to allow a work blank in the notch 120 to slip out of said notch onto table 54 ep ementwith the feed bar inecl'ianlsni ahd the cam q n I is so located with reference t other cams heretofore referred to that iz dropping of the feed blank occurs ,1, Xactly the proper time to cooperat'e'wit other operations of the machine.

\Vhen a blank 52 has been deposited either by hand or by the carrier 86 on the table at. the left hand end ofthe carrier 44-46 and the machine is operating, the movement of the carrier block 48 causes the blank to travel to "the right through the machine as viewed in Figure 5 along the top of the table 54 between guides 53, adjustable to and from the work by bolt and slot c0nnections to the frame, until itrcaches a posi tion in the plane of the line 11 of Figure 5, viz: the first forming station. In this position shown in Figure 11, the blank 52 is first positioned or gauged by gauging steel 12 1 on the under side of horn 126. It is next rigidly clamped to the under side of the lIOI'Il by the end of clamp plate 128. This clamp plate 128 extends as shown in Figure'5 for a substantial distance lougtudinally of the machine and intermittentlyholds the work at dill erent bending stations hereafter described. This clamp plate is operated by a vertically reciprocal cross-head 130 carrying at its lower end a roller 132 traveling on a cam 134 on shaft 38, the cam being so proportioned that the clamp will be applied to the work at proper intervals as it is carried by the mechanism 44-16 from left to right through the machine as shown in Figure 5.

Having been clamped in the position of Figure 11, it is engagedby the first forming slide or tool 136, vertically reciprocal through the agency of a roller 138 which it carries, traveling on cam 141) on shaft 38 and always held in contact with the cam by springs not shown. The working part of this tool 136 consists of two parallel bending tools 1412 and 1441-, operating on opposite sides of clamp 128 and the adjacent part offeed bar 44 to give the adjacent portion of the work blank 52 a U-shaped bend around an end portion 145 of the horn 126. The bending tool 142in this operation thus makes what is ultimately the bridge 146 of the finished products, shown in Figure 1. The tool 144: makes an end 1 18 of said finished product. The upward reciprocation of the tool 136 and its ultimate return to lowered position leaves the product in the position shown in Fig. 12 in which position theclamp 128, having been released, it is moved by the carrier device 44.46 along the horn from the position of line 11 to the position of line 12 of Fig. 5. In doing this, it t'avels through one intermediate position of the car rier 4 l-46 in which no bending is done on the work. In passing through this idle station just described, the bridge 1:16 of the work blank enters at 150 a slot152 formed in horn 126. On the underside of the horn, the lower edge of the part bordering this groove is cut away in the notched recess 151 for the reception of feeder teeth 50.

lVhen the particular work blankbeing hes the position of Figure 12 with its ltniidge part 1 16 in the slot 152 in the horn 126, it momentarily clamped by clamping jaw 128 which at this point carries a projecting plate 156 which covers that portion of the work which was formed at the first station and by the mechanism shown in Figure 11. The work blank is now bent in a counter-clockwise direction over the top of horn 126. This bending action is position shown in Figure produced by a rigid to left ironing or scraping movementby a forming steel 158 carried on lever 160 pivotally mounted at 162 on the upper end of a lever 16$ journaled on a suitable supporting shaft or bar 166, there being on the lower end of the lever 164 a. cam roller 168 traveling in a cam track 170 in a cam wheel 172 rigid on shaft 38. The end of lever 160 opposite to forming member 158 is provided with a roller 174 traveling on a cam 176 carried by bracket 178, adjustable by means of a bolt 179 on frame 16. The cams 170 and 176 are so shaped and correlated that forming bar 158 sweeps the engaged portion of the work blank over onto the top of the horn 126 thus forming portion 180 of the finished product. This may be curved or straight, depending upon the form of the upper surface of the horn 126 at this point. Further rotation of shaft 38 and cam 170 returns the parts just described to the position of Figure 12 in which position the clamp on the work is released.

The feedingmechanism 1t-- 16-4l8 now operates to move the work along into the 13, under rigid, serving the funcstationary guide block 182,

tion of preventing the outer or right hand end ot the horn 126 from springing up away from the feeding mechanism PL-4.6 and actmg as an upper aw in which section 180 of the finished product is clamped by plate '128. As soon as the section 180 of the work reaches the position of Figure 13, clamp 128 acts to hold it against jaw 182 whereupon the next portion 181 of the finished product is bent down ard over the horn by a downward, wviping movement of forming steel 186. The mechanism for causing this steel 186 to perform this desired function consists in a lever 188 having at its opposite end a 'U-shaped notch 190 by means of which it slides over a non-circular rotatable stud 192. This U-notch sliding connection with this stud allows the steel 186 to be reciprocatingly moved so as to cause it to follow either a straight line or any predetermined curved line desired in its downward sweep, bending the part 184. of the work. Lever 188 is pivoted near its middle by a suitable pin connection 1.94 to a verticall. reciprocal connecting rod 196 having its upper end equipped with a roller 198 traveling over a stationary cam face 206 and urged into contact there with by a spring not shown. The lower end of connecting rod 196 is pivoted at 202 to the short arm 20 1 of a bell crank pivoted 'at 206 whose longer arm 208 carries a cam roller 210 traveling in a cam slot 212 in a rotatable cam wheel 211 on shaft 38. Cam track 212and the cam 200 are so shaped as to, in a complete rotation of the shaft 38, cause a downward, wiping movement of steel 186m the path desired to properly till form the work section 184 and to ultimately return all of the parts except the work to the position shown in Figure 13 and to there release the clamp 128.

The horn 126 at the point illustrated in Figure 13 is supported on its left hand side as viewed in that figure by a small block 216 as shown, the same being rigidly secured by any suitable means to clamp 128.

The operation carried onby the mechanism of Figure 13 having been completed, the feeding device 4446 carries the work into the position shown in Figure 14 wherein the final work section 216 is produced by a left to right swinging action of forming steel 218 carried on a lever 220 pivoted at 222 on the upper end of a lever 224 pivoted on pin 206 heretofore referred to, the lower end of this lever 224 carrying a roller 226 traveling in a cam track 228 in cam wheel 230 on shaft 38. The end of lever 220 away from steel 218 carries a roller 232 traveling on the underside of a stationary cam 234. Cams 234 and 228 are so shaped that on a complete revolution of shaft 38, steel 218 travels from left to rightas shown in Figure 14 across the under side of the horn, thus bending final section 216 of the work to final position and thereafter returning the steel 218 to the initial position shown in the figure. This completes the bending operations required to form the finished product or products shown in Figure 1. At this point, the finished product has reached the ends of the finger bars 44 and it is no longer moved by that part. It is, however, moved by the next formed chaplet coming into the position of Figure 14 out of that position to a position justat the right of section line 10 of Figure 6 wherein it is directly over squeeze block 236:-t-he lower jaw member of a clamp whose upper jaw is the right hand end of member 182, heretofore described. Block 236 is detachably secured by any suitable means, as, for instance, screws to a lever 240 pivoted at 242 to a. bracket 244 on the side of the machine. This bracket is adjustable vertically of the machine through a conventional pin and slot connection 246.

The non-pivoted end of lever 240, and squeeze block 236 carried by it, is vertically reciprocal through the agency of a double link 248 pivotally connected at 250 to the shorter arm 252 of a bell crank pivoted at 251., the longer arm 256 of the bell crank carrying a roller 258 traveling on a cam 260 on shaft 38. Roller 258 is held on cam 260 by a conventional spring not shown. The construction is such that at each complete revolution of shaft 38. squeeze block 236 is moved upward with suflicient power to clamp the particular section of the finished product which is above it against member 182 and thus set the previously bent parts in the final desired position determined by the end of the horn 126 which is still within it. In each complete revolution of the shaft 38, the squeeze block 236 is withdrawn from the previously compressed finished product sufiiciently so that it can under the urging of other chaplet-s behind it be forced out into the chute 262 down which the finished product drops into any suitable receptacle provided for the purpose.

Guide block 182 is made up of two parts: a forming plate 182, which is shaped to correspond to the particular chaplet which the machine is at a particu air time engaged in making, this plate being detachably securable by any suitable means, as the screws 264 to the main block 182* which is in the particular case here illustrated a casting adjustably secured by pin and slot connections 266 to an overhanging arm bracket 268 suitably secured to the frame of the machine. Member 182 is verticall adjustably positioned by set screws 270 in the bracket 268.

The horn 126 is detachably secured to a bracket 272 by any suitable means as, for instance, the cap screws 274. This bracket, itself, is detachably secured in position on the frame 18 by cap screws 276. The machine is equipped with horns 126 of differentshapes corresponding to the finished product which is to be produced and on starting to produce a given product, the horn for that product is inserted in the machine, by methods which are entirely obvious from the foregoing description of the parts.

In the complete operation of the machine, material 80 is fed downward as shown in Figure 5, severed and delivered onto the feed mechanism 4446 which carries it step by step from left to right as viewed in Figure 5 through the successive positions in the machine during which progress it is bent Ill" successively as shown in Figures 11, 12, 13

and 14 and is finally squeezed to finished form, after which it is passed out of chute 262, all as fully heretofore set forth.
