SPRING-WHEEL Specification of Letters Patent.

Patented July 19, 121231.

Application filed December 30, 1919. Serial No. 3fl845.

To all whom t may concern.'

Be it known that I, HARVEY MYERS, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Spring-lllffheels, of which the following is a specification.

The present invention relates to certain new and useful improvements in spring wheels, and has for its object to provide a device of this character which embodies novel features of construction whereby the load superposed by a vehicle is resiliently supported and the shocks and jars incident to the movement of the vehicle over uneven roads effectively taken np and cushioned.

Further objects of the invention are to provide a device of this character which defrom metallic springs and is not liable to break or get out of repair, which is comparatively simple and inexpensive in its construction, and which provides means for excluding mud and dirt from the springs.

With these and other objects in view the invention consists in certain combinations, arrangements and associations of the parts, as will more fully appear in the following description, the novel features thereof being pointed out in the appended claim.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a fragmentary portion of a spring wheel which is constructed in accordance with the invention, portions being broken away and shown in. sections.

Fig. 2 is a transverse sectional view through the rim portion of a spring wheel embodying the invention.

Corresponding and like parts are referred to in the following description and indicated in all of the views of the drawings by the same reference characters.

Referring to the drawings, which illnstrate one possible embodiment of the invention, the numeral 1 designates a fragmentary portion of the felly of a wheel, and 2 one of the spokes A floating ring 3 surrounds the felly 1 in a spaced relation thereto, and a series of coil springs 4 are interposed between the floating ring and the fellyP A band 5 surrounds the felly 1 and fits tightly against the same. the band formed with an integral flange 6 which fits against one of the side faces of the felly, while a corresponding plate 7 is fitted against the opposite side face of the felly and engages the opposite edge of the band. rlhe flange 6 and plate 7 are connected by a series of bolts or rivets 8 which extend transversely through the felly and provide a means for fastening the banc 5 rigidly in position. The outer edge of the plate 7 extends beyond the band as indicated at 7, and the opposite edge of the band 5 formed with a corresponding short flange 8 which projects in the opposite di-V rection from the before mentioned flange 6.

.The coil springs f are radially disposed with respect to the wheel and have the ends thereof engaged by corresponding projections 10 on the band 5 and floating ring 3. These projections serve to position the ends of the springs and to keep the springs in proper place during the operation of the wheel. The two opposite edges of the floating ring 3 are provided with inwardly extending flanges 11 and also with outwardly extending flanges 12, the flanges 11 having an opposed relation to the flange 9 ofthe band and the outer periphery 7L of the plate 'i' and being arranged to engage the said members when the floating ring reaches the limit of its movement in any direction. The ontwardly extending flanges 12 of the floating ring 3 assist in engaging a tire 13, the middle portion of the tire being shown as interlocking with an annular dovetail rib 14: on the exterior of the ring.

Guide plates 15 are provided at the sides of the felly and arranged to bridge or span the distance between the folly and the floating ring, said plates being rigidly secured to one of the said members and having a sliding engagement with the other member so as to directthe floating ring in its 1novements and hold the same against lateral displacement relative to the felly and wheel. In the present instance the opposite edges of the floating ring are shown as rabbeted at 16 to receive the outer edges of the guide plates, said guide plates being secured to the floating ring by the bolts 17 which extend transversely through the same. The inner edge portions of the guide plates 15 have a telescoping engagement with the flange 6 of the band 5 and the plate 7, although they One edge of V"having the l around the Wheeh that the Heating ring is mounted so that it iit closely against these members and serve' to exclude dust and dirt from the spring receiving space between and the ioating ring. These inner edge portions of the guide plates l5 are connectediby tie bolts 18 which extend through clearance openings 19 `in the flange 6 and plate 7 and also through corresponding clearance openings or notches 20 in the'outer Vperiphery of the telly l. rllhese notches 20 are shown as mouths thereof closed by the band These tie bolts 18 have a limited movenient in allrlilrections so that they do not interfere with the cushioningV action of the springs,falthough they Will prevent the floating ring- VV-roin creeping circuni'ferentially It will thus be obvious can `move relatively to the Wheel, although any such 'movement will be resisted by the springs 1l Which operate to take up and cushion the usual shocks and jars which are incident to the passage of a vehicle over an 1 uneven road surface.

`the Wheel and telly` Having thus described iny invention what I claim as new is A spring Wheel including a elly provided With clearance openings in the periphery thereof, a bandiitted tightly upon the telly and extending over the mouths of the clearance openings,'bearing plates applied to the sides of the elly and having openings therein registering with the clearance openings of the elly, a ioating ring surrounding the `telly in spaced relation thereto, 'springs interposed between the loating ring and the telly, guide plates bridging 'the space between the vfloating ring and the telly, said'guide plates being secured to the loating ring and slidably engaging the bearing plates o the telly, and tie bolts connecting the guide plates and extending *throuO'h the clearance openings or' the felly,

inoveiiient 'of the bolts from the openings being prevented by the band.

In vtestimony whereof I aflix my signature.

HARVEY Mrnns.
