Application filed November 16,1912. Serial No. 731,759.

To all whom it may concern:

Be it known that I, EDGAR W; Penny, a-

citizen of the United States, residing at Georgetown, in the county of Georgetown and State of South Carolina, have invented new and useful Improvements in Wheel- Hubs, of which the following is a specification.

The general object of the invention is to improve the construction of spring wheels shown in my co-pending application Number 628,504, filed May 20, 1911. And to this end the invention consists in constructions for permitting angular movement of the relatively movable parts of the wheel and means for cushioning such angular movement. 7

Other objects will'appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, 1n which: 7

Figure 1 is a view partly in section and elevation of the hub portion of the wheel. Fig. 2 is a cross section on the line 22 of. Fig. 1. Fig. 3 is ardetail elevation of the guide. Fig. 4 is a detail perspective of one element of the cushioning device.

The spokes 5 are arranged in a circular, portion 6. In the present instance, hellcal compression springs 7"7 are interposed between the circular portion 6 and the sleeve 8 their ends being arranged in depressions 9 in the sleeve and depressions 10 in the circular portion 6.

The guide members 11 and 12 are screwed onto the opposite end portions of the sleeve '8 and the radial arms 13 of these guide members bear on the sides of the circular portions 6, while the circular portions of the guide members with which the arms are formed integral, cover the circular space surrounded by the member 6 all of which is shown in Figs. 1 and 2.

In either side of the circular member and between the adjacent sides of adjacent arms 13, are formed a pair of pits l4 and 15 and located in these pits are helicalcompression springs 16. Between the adjacent ends of the pits are arranged stop blocks 17 and arranged over the pits are plates 18 having lugs 19 which project into the pits an'd'bear on one end of the springs. The lugs of adjacent plates are located adjacent to the remote ends of the plates while the adjacent ends of the plates are normally spaced from the stop blocks 17, as shown in Fig. 1. The remote ends of the plates bear on adjacent sides of the arms 13-13 so that when the circular member 6 is moved relatively to the member 11 and in one direction, certain of the lugs will effect the compression of certain of the springs, while the other lugs will effect the compression of the springs when the said circular member is moved in the opposite direction and relatively to the guide member 11.

Now inasmuch as the circular member is :supported or rests upon the springs 7, the wheel and axle are permitted to move relatively to each other, such relative movement being in a direction perpendicular to the axle, and since a space exists between the adjacent ends of the plates 18 and the stop blocks 17 an amount of angular movement by the circular member. 6 is permitted within the limits of this space. But such angular movement on the part of the circular member 6 will always be against the action of the springs 16 which, of course, will operate to absorb the jolt or jar which the wheel receives, to effect such angular movement.

The guide members 1111 are provided with screw threaded bosses 20- 2O onto the inner of which is screwed a cap 21 which is adapted to cooperate with a washer 22 to form a race for hearing balls 23. A nut 24 screwed onto the outerend of the axle 25 prevents displacement of the wheel and is adapted to cooperate with a cap 26 screwed onto the outer boss 20, to provide a race for the bearing balls 27.

For preventing displacement of the parts I employ the rings 28-28 which are arranged over the opposite sides of the circular member 6 and retained by suitable fastening devices such as bolts 29, which pass through the said rings, stop blocks and spokes.

What is claimed as new is: V

A wheel hub comprising a sleeve, a circular member surrounding the sleeve, springs interposed between the circular member and sleeve and having lateral sockets, guide members screwed onto the opposite end portions of the sleeve and having radial arms bearing on the sides of the circular member,

the circular member, plates having portions arranged for preventing displacement of bearing on one end of the s arings and arsaid plates. 1 ranged so as to have their acent ends in In testimony whereof I affix my signature spaced relation and their remote ends bear in presence of tWo Witnesses. V

ing on adjacent sides of the arms of the 7 EDGAR W. PERRY, guide members, stop blocks interposed be- 1 Witnesses:v a tween the adjacent ends of said plates, and JOHN A. DoNEGAN,

rings secured to the spokes of the Wheel and G. JAMES CRONIN;
