5 RESILIENT WHEEL;

Application filed August 5 -1915. Serial No. 43,764;

To all whom it may concern Be it known that we, CHARL r is RIOEiand THUniirAN RICE, both citizens of the United States, residing atEas't Sparta, in 5 the county of Stark and State of Ohio, and Canton, in the county'of Stark and State of Ohio, respectively, have invented a new and useful Resilient Wheel, of which the following is a specification.

This invention relatesto resilient wheels and has'more especial reference to that type of resilient wheel which is provided with a The object ofoiir invention is to provide a wheel of the characterreferred to, the construction of which will reduce the jar upon resilient wheel, possessing the advantages above mentioned which will be simple, in

construction, inexpensive to manufacture and durable and efficient in use.

-A further object is tovprovide a wheel of this construction in which .there will be practically? no noise or rattling caused by partsrduringthe movement of the several the operation of the wheel,

" \Vith these objects in view the invention consists in the novel-constructionand arrangeinent' of parts, hereinafter described,-

illiistrated in th'e ac'companying drawings,

ed claiii'i s, it being understood that various changes in the form, proportions, size and minor details of construction may be iiiade within the scope of the appended claim,

The annular case a ing 4, the form of which'is ,best illustrated in Fig. 2 is locatedaround the fell-y and connected thereto by means of the series of bolts 5 which pass through. said casing and i through enlarged apertures-.6 located in the venting any rattling ofthe casing. A iiiiid guardcomposed of spring members 9 covered-upon-each side with a strip of rubber or similar material lOis connected. to the telly .by nails 11 or their equivalents and located against. the outer faces of the casing for the purpose of preventing dust or mud frplm entering between said-casing and the e y. a

"extremit es of the ad uSting' screws 14, said screws passing through suitable SCINX' threaded apertures 15 n the-tire 3 and-provided with jam nuts 16 located against the inner face of the felly, Eachofthe adjust ing plates 12 is provided with a central aperture l7 and: with radially disposed V- shaped notches 18 diametrically opposit tox each O'tlier-and extei'idii igr'froni the outer edges of the adjusting plate to said central aperture- The rocking members 19 are of substaiitially annular form and are provided with the internal annular shoulders--20. E-ich of the rocking .nienilairs .19 is provided upon its lower face with a pair of diametrically opposite V-shapedteeth. 21 arranged to be pon the Located around the periphery of the casingl. within the annular depression 22 and in radial alinement' with the centersof the adjustii'ig plates 12 isa series of-screws 23- the heads ofsaid screws being counter-sunk within the outer face of the casing, jam-nuts 24'being provided upon. said screws and located against the'inner surface of the casing.

The rounded extremities of the screws23'are' opposite face for-the purposeof receiving one extremity of the cylindrical resilient member 28, said resilient member being preferably composed of soft rubber. The lower extremity of said resilient member is located through the annular rocking member 19 and through the central aperature 17 e posed of soft rubber or similar material is.

ocated in the annular depression 22 which is provided around the periphery of the easmg.

With the construction above described, the

- coil springs 29 cushion the wheel while the resilient members 28 prevent excessive compression of said coil springs thus adding a further cushioning effect to the wheel. Owing to the construction by which the rim or casing is connected to the telly only by means of the bolts. 5 which pass through the enlarged apertures 6 in the lugs carried upon the felly, said bolts are free to move in any direction in said apertures, thus allowing a slight rockingmotion of the cushion members when the wheel is suddenly started or stopped, said cushion members rocking between the pivotal points 23 and the V-shaped teeth 21.

The adjusting screws not only provide means by which the springs may be adjusted to center the rim or casing with relation to the axis of the wheel but they also enable the tension of the spring to be adjusted according to the weight desired to be imposed upon the wheel.

For the purpose of convenience the casing 4. is made of a plurality of sections riveted or otherwise attached together as illustrated in Fig. 1 of the drawings. By the construction of cushion members disclosed herein each cushion member comprises a double pivoted spring, pivotally connecte to the telly and to the casing at its opposite extremities. As best shown in Fig. 2 each reaccompanying adjusting plate, the upper extremity of said resilient member being spaced away-from the disk 26 and arranged to be received within the socket 27 of said disk when the accompanying spring 29 is put under pressure, thus relieving the spring of a part of the weight or strain and at the same time producing the desired cushion ef fect. The bolts 5 will come into action where there is any difiiculty in starting the wheel, contacting with the walls of the apertures 6 and causing the tire or casing to move circumferentially with the telly.

\Ve claim:

In a vehicle wheel comprising a folly and an annular casing surrounding said folly, a set of cushioning devices spaced radially aromntthe wheel and located between the felly and the casing, an adjusting plate provided with a central aperture laterally disposed V-shaped grooves in the upper face of said plate and sockets in the lower face of said plate, adjusting screws located through screw threaded apertures in said felly, the extremities of said screws being received within the sockets within said adjusting plate. an annular rocking member provided with an internal annular shouhler, V-shaped teeth provided upon the lower face of said rocking member and located within the V-shaped grooves within said adjusting plate, a cylindrical resilient member located through the a )erture in said. plate and resting upon the ielly, a disk provided with a socket. said socket receiving the upper end of said resilient member, said disk provided in its upper face with a rounded socket, apin attached to the inner face of said casing, the extremity of said pin lo cated in the rounded socket of said disk and a coil spring interposed between said rocking member and said disk.

In testimony that we claim the above, we

have hereunto subscribed our names.
