Definitions
- the invention is a quick detachable elastic tire and the object of the invention is to provide an elastic tire that may be made in standard sizes to be mounted on fellies of ordinary wheels.
- a further object of the invention is to provide a tire of this character with a minimum depth consistent with the requisite strength and springiness, in order that the resulting wheel shall have just about the same appearance as an ordinary pneumatic tired wheel.
- a still further object is to simplify and thus cheapen the cost of the tire.
- the invention consists of a pair of opposing U-sectioned metal bands forming inner and outer rims concentrically arranged and between which the springs to give the necessary resilience, are arranged in a particular manner.
- the innerrim or band is made of such a size that it will nicely fit the felly of a standard size wheel and is secured thereon by any suitable means.
- outer band preferably carries a rubber tread portion and side plates to close in thespace between the two rims.
- the provision of the two U-sectioned bands not only lessens the depth of the tire, but provides advantageous supports for a plurality of brackets secured in pairs to the inner and outer rim respectively on opposite sides of the wheel, between which the springs are stretched so as to lie in a direction parallel with the axis of the wheel, these springs engaging hooks on the free ends of the brackets so that they may be easily attached or detached.
- FIG. 1 is a side view of a portion of the elastic tire according to the present invention, partly in elevation and partly with one of the side plates removed to disclose the interior of the tire.
- Fig. 2 is a cross section through the tire and a pair of the spring-supporting brackets.
- Fig. 3 is a perspective view of oneof the spring-supporting brackets and
- Fig. 4 is a similar view of another of the supporting brackets.
- 1 indicates the inner rim having the outwardly extending side flanges 2 and of such size as to nicely fit the felly of an ordinary standard size wheel, said rim being secured to the felly (not shown) by any known means, such, for instance, as the well known wedges which would enable the rim to be taken off the wheel very quickly.
- rim 3 is the outer rim of larger diameter, but preferably about the same width and having the inwardly extending continuous side flanges 4:. It will thus be seen that the rims 1 and 3 are U-shaped in cross section at any point therearound and consequently are very easily and cheaply produced. It should be mentioned that the flanges 2 and 4: extend toward each other only a suflicient distance to allow of a fair amount of movement of one rim in relation to the other in the plane,
- the side plates 5 and 6 are rigidly secured to the rim 3, against the flanges 4 thereof, through the medium of cross bolts 7 extending through the flanges of the said rim 3 from side to side. These side plates 5 and 6 each extend a little beyond the rim 3 as indicated by the numeral 8 in order to provide achannel within which is disposed a rubber tread 9.
- brackets 10 are spring-supporting brackets arranged, in the angles formed by the flanges 4L and the rim 3, at intervals therearound and staggered from side to side, that is to-say, each bracket on one side of the rim comes between two brackets on the other side.
- Fig. 2 one of such brackets 10 appears on one side of the rim, but it will be understood from the foregoing description that such brackets are arranged on both sides of the rim in alternate arrangement and in the angles formed by the flanges 4.
- Each of the tongues 11 is provided with a pair of holes 14 and 15 engaged by a hook 16.
- This hook has a threaded-shank por tion 17 extending through the hole 14 and provided with a tightening nut 18, while the head portion of the hook is provided with a. shoulder 19 and looped around therefrom until its free end 20 engages the hole 15. It should be mentioned that the hooks 16 in the normal position of the wheel lie approximately midway between the rims land 3.
- brackets 21 are brackets secured to the riln in the angles formed by the flanges 2, these brackets being arranged on both sides of the rim in alternate arrangement so that each bracket 21 on one side of the rim comes opposite one of the brackets 10 on the other side of the rim 3.
- the brackets 21 are each secured to the flange 2 and the rim by rivets 22 and are further strengthened across the angle. by the provision of a web or strut 23, and, outward of the flange, each of the said brackets .21 is extended to a point approximately midway between the two rims to form a tongue terminating in the integral hook 24.
- the plates 5 and 6 move with the rim 3 and slide alongside the flanges 2, which latter assist in guiding the plates in their movement and in forming such rigid support as is required when the wheel skids or slides as a whole laterally.
- the hooks 24 are rigid while the hooks 16 are adjustable and this is a feature which greatly helps in the assembling of the tire, particularly as each spring is slightly stretched in the fixed POST? tion. After hooking the spring on the rigid hook the adjustable hook can be moved in a longitudinal direction to stretch the spring by simply tightening up. the nut 17 Attention is called to, the fact that the tire according to the invention can be very quickly applied to the felly of an ordinary automobile. or other wheel, and further that in the tire according to the invention, specialattention h en given o. h detail of construction in order to provide great strength to contend with skidding movements of the wheel.
- channel bar type of structure which gives a high rigidity for the amount of material used.
- These channel members may be made relatively weak as they are not designed primarily to withstand any severe strains. Tension of the springs is transmitted through the relatively heavy brackets directly to the web portion of the channel members. As these web portions are reinforced in the case of the outer rim by the resilient tread members and in the case of the inner rim by the felly of the wheel, there is no particular necessity for using heavy metal in the channel members.
- the side plates Normally these plates act merely to inclose the space between the rims and as the tension of the springs is not transmitted through the side plates, they may be constructed of thin sheet metal. Further it is noted that the channel members need not be of the same thickness of material for the inner rim is not as much subjected to twisting strain as the outer rim and therefore may be made of thinner stock than that used for the outer rim.
