To all whom t may Be it known that I,

concern.'

Hans A. MEINHARDT, residing at Pittsfield, countyof Berkshire, and State of Massachusetts, have invented a new' and ImprovedA Resilient Tire, Aof which the following is a specification'. This invention relates to a resilient tire of novel constructiomwhich is of ysuperior strength, and distributes the pressure over an extended section thereof', so that the re- ,l

siliency of a large portion of the tire is utilized for obtaining smooth running.

In the accompanying drawing: Figure 1 tire embodying my isa cross section of a invention; Fig. 2 a longitudinal section partly in side view of a portion thereof; Fig. 3 a section on line 3-3, Fig. 1, with the" case tubev omitted, and Fig. of a modification of the core. v

The casetube 10 yof the tire is held in suitable manner to the wheel rim 11, it being shown to be proyided with flanges 12enclamp rings'fl that are bolted to the rim. Within case tube 10 are fitted a plurality of springs A o'f likey construction, each spring comprising a suitable number of convolutes that lie closely ner face of the case tube. SpringsA are so disposed that the convolutes of each spring are intercoiled with the convolutes ofthe or inother words.

' each spring is overlapped at its ends by the left' side,

` construction shown,

two flanking springs. In this waythe resilient core of the tire is greatly reinforced and weak spots between the springs are prevented, while furthermore any one spring can be replaced without discarding the other springs.

As more fully shown in Fig. 1, the springs are so shaped .that each coil thereof is provided with an eye '14 at its right and or about midway between' wheel rim and tread. -At the tread, the coil is provided with an additional oblong' seater eye 15 which 'may be formed by doubling the coil partly upon itself. Thus with the the wire@ extends say` from the right eye 14 first below the opening 15, then above the same, then again below the opening and then to the' left eye 14, but it is obvious that this peculiar arrangement niay be modified without departing frein the spirit of my invention.

At its mner portion, each coil is attened nected in suitable manner, 11 a detail' against the 1nas at.- 16, while a hook 17 is-forined at each end yof each of the springs. These-hooks are adapted to be projected over the beveledv edges of a stift' metal coils and fits closely flattened sections 16 there! ring 1 8 which isen.- compassed by. the against the inner of. The edges of this ring are notched as at 19 to seat the coils and properlyspace the same. Tntermediate ring 18 and the wheel rim,`.tliere,is arranged a secondstiff metal ring 20 which extends over 4the flattened sections 16`and is provided with outwardly extending diverging' flanges 21 that project between springs A and case tube 10.

Through each set of alined eyes 14 of the several spring coils is threaded a common wire binder 22, the ends of which are oonso that each wire is endless. Thus when two eyes are formed on each coil, two bindingv wires are employed, the number of suoli wires changing with the number of eyes.

wWithin the openings 15 of the several spring coils, is accommodated a further resilient binder which is also endless andthus connects the various spring coils at the tread. This binder is in Fig. 1 shown to consist of' a steel band 23 formed of a suitable number of superposed layers while in Fig. 4 it is shown to be composed of a -convoluted wire band Q4, the coils ofV which are arranged side by side. In both cases the ends of the binder are of course securedito .the body thereof, so as to prevent spreading.

In assembling the parts, springs A are fitted over ring 18, intercoiled with each other in the manner previously described, and then connected to theiing by hooks 17. Next ring 20, is slipped edges are turned outwardly to form the diverging flanges 21, thereby interlocking the parts. Binders 22, 23 are now threaded through openings 1l, 15 and the ends of each binder 22 are connected with each other while the ends of binder 23 are secured to the body thereofv after which the' device is in condition to be fitted into the case tube.

'It will be seen that in use, the road pressure will flat-ten the spring convolutes as well as the binder 23 at the tread. But as into ring 18 and its this binder aswell as the auxiliary binders "22 are endless vand cannotfchange their perpherallength, they will in yielding, transmit the strain to al large group ofadditional wire coils located to the right and left of,

land a series of inclosed spiral coils placed endWse of each other -to collectively form a, sectional spiral core, the end convolutes of eachcoil entering the end convolutes ofthe flanking coils. K I
