SPRING wanna.

.7'0 alt "AU/207271 it may concern: I

Be it known that I, ELD'JH l). ANonRsoN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful. Improvements in Spring Wheels, of which the fOllOWiIlg is a specs fication.

The present invention relates to spring wheels and has for ,its principal object to provide spring means between the tire or rim and the felly of the wheel.

Another important object of the invention is ito provide means between the felly and the rim for imparting the rotary motion of the former to the latter said means being of a resilient nature.

A still further object of the invention to generally improve upon spring wheels of this character by providing a device which will be extremely simple in construction, reliable in operation, capable of being manufactured at a comparatively low cost, and well adapted to the purpose for which it is designed.

In the drawing Figure 1 is a fragmentary elevation of a wheel embodying my invention, portions thereof being shown in section,

Figure 2. is a transverse section taken therethrough,

Figure 3 is a fragmentary longitudinal section through a portion of the wheel,

Figure 4c is a transverse section theretliroiigh taken substantially on the line 4-4 of Figure 1 looking in the direction of the arrow,

Figure 5 is a detailed longitudinal section showing interior portions of the wheel in elevation, and

Figure 6 is a transverse section through the wheel, taken substantially on the line (i(% of liigure '1. looking in the direction of the arrow.

Referring to the drawing in detail it will be seen that a hub of any preferred construction .1. provided with the conventional spokes 2 extending therefrom and upon these spokes there is mounted a felly 3. A U- shaped annular plate 4: is mounted on the outer periphery of the felly 3 and has circular plates 5 attached thereto and spaced therefrom by the rings 6. These circular plates 5 are provided with recesses 7- for receiving suitable packing 8. A pair of c1r cular plates 9 are associated with the plates 5 so as to engage their inner faces as is shown to advantage in Figure 4-. These inner plates 9 are attached to the flanges of the rim. 10 which has mounted thereon a demountable rim 11 of any preferred construction on which is carried a tire 12 either solid as shown or pneumatic or of any other preferred construction.

A plurality of curved substantially U- shaped springs 13 are disposed between the, rim l0 and the plate 4 attached to the felly These springs have their ends terminat ing in eye members for receiving the bolts '15 which pass through the-flanges of the rim 10 and through. the -flanges of the plate 1 thus resiliently mounting the rim 10 in respect to the felly 3. It will be seen that the plates 9 and 5 form a housing for these springs and for other parts to be described hereinafter.

A plurality of boxes 16 are disposed beof each boxi16 and these flanges are riveted to the rim 10 in any suitable manner such is shown at 20. Inside of each box ad jacent the other end there is mounted a suitable resilient lining or member 21 for a purpose which will be evident hereafter.

A plurality of plungers 22 radiate from thebase of the U-shaped plate 4 being held in place by having their flanges 23 riveted thereto as at 24 or in any other suitable manner. The outer ends of these plungers are slotted as at 25 for receiving the bolts 17 in the boxes 16. A pair of springs 27 is mounted on each of the bolts 17 one on each side of the plunger 22 situated adja centthereto. The springs 13 normally hold the rim separated from the felly and thus the parts lwill be positioned substantially as is disclosed in Figure 1. VVheu the springs 13 are compressed the outer end. of each plunger will move toward the outer end of its corresponding box and may even abut the resilient lining 21. The springs 27 take up any shock which will be caused by the movement of the felly such as when the clutch is first let in upon an automobile and thus there would not be such a jar asthe machine was first propelled forwardly or rearwardly. This structure, of course, is

adapted to other vehicles and uses this pur tioular one merely being given by ay of example.

It is to be understood that the present embodiment of the invention has merely been disclosed by Way of example and that numerous changes in form, material, and in i the combination and arrengement'of parts as tween the telly and the rim, a plurality 01?. boxes attachedto the rim, plungers extending from the felly into the boxes, a bolt extending longitudinally of each of the boxes, said plungers being provided With elongated slots for receiving said bolts, and spring elements disposed on each bolt one on each side of each plunger.

In testimony whereof I affix my signature in presence of two witnesses.
