SPRING-WHEEL.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed April 12, 1913. Serial No. 760,788.

To all whom it may concern:

Be it known that we, GLos'rnr. J. (iamnrrr and HERBERT C. GARRETT, citizens of the United States, residing at Richmond, in the county of lVayne and State of Indiana, have invented certain new and useful. Improvements in Spring-lVheels; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends il'nprovcments in spring wheels and relates more pa 1'- ticularly to those of the type wherein the folly is supported by a plurality of cushioning members.

The, primary object of the invention is to provide a spring wheel which shall be of extremely simple construction, cheap to manufacture, and very strong and practical.

Another and more specific object of the invention resides in the provision of a wheel of this nature having a folly which is supported b a plurality of expansive swings and a plurality of resilient blocks, which latter are carried upon the extremities of the spokes.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction. combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete umlersta-nding of our invention, reference is to be had to the following description and accompanyingdrawings, in which,

Figure 1 is a fragmentary side elevation of our improved spring wheel, one of the side plates being partly broken away, Fig. 2 is a transverse section taken on the plane of line 2--2 of Fig. 1, and, Fig. 3 is a similar view taken on the plane of line 3 3 of Fig. 1.

In the following description and accompanying drawings, similar parts will be referred to and designated by like characters of reference.

Referring in detail to the drawings by numerals, 5 designates the hub, 6 the spokes, 7 the felly, 8 the rim, and 9 the tire of our improved spring wheel. A block 10 is positioned between each pair of spokes and engages lugs 11 formed thereon. These blocks are situated near the outer extremities of the spokes and have their outer faces recessed, as

indicated at 12, to provide seats for the expansive spiral springs 13, which bear at their outer ends against the inner face, of the felly 7. To prevent the springs moving relative to the folly, we provide lugs 14: which are mourned upon base plates 15 and the latter are secured in recesses formed in the folly. 'lhe lugs extend into the coils of the springs and by engaging the same prevent a movement thereof relative to the felly. To provide further cushioning means for the folly, we employ a. plurality of resilient blocks 16 which are preferably formed of rubber and which are interposed between the extremities of the spokes and said folly. A U-shaped frame 17 is secured to the end of each spoke and embraces a pair of blocks 16 for the purpose of holding the same in proper position. Stop members 18 a re secured to the felly by means of the base plates 15) and one of these lnelnbers projects between each pair of resilient blocks and prevents a circumferential movement of the telly relative to the spokes. It is to be noted that the cushioning blocks extend beyond the U-shaped frame and that the stop members 18 terminate short of said frame so that the proper spring action of the wheel is not interfered with.

For the purpose of holding the blocks 10 and 1G and the folly 7 against lateral movement relative to the spokes and hub, we provide annular side plates 20 and secure them upon opposite sides of the wheel by means of the bolts 21 which extend through the spokes (3. These plates lic flush with the sides of the spokes and with the flanges formed upon the blocks 1.0 and extend outwardly to with in a short distance of the ribs or flanges 22 formed upon the rim 8. it will be noted by reference to Figs. 2 and 3, that these side plates do not interfere with the contraction and expansion of the springs and resilient blocks, but by engaging the latter, serve to hold them against lateral movement. These plates also act as a brace for the felly and prevent it moving out of proper alinement with respect to the remaining portion of the wheel.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that we have provided an OK tremely strong and durable spring wheel which may be readily assembled and which will effectually absorb the shocks and jars incidental to rough roads. By removing either of the. side plates 20 the important parts of the wheel are made easily accessible and they may be quickly removed and replaced by others if desired.

It is to be understood that while we have shown and described the preferred embodiment of our invention, we do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope of the invention.

Having thus described our invention, what we claim is:

l. A spring Wheel including a hub, a plurality of spokes radiating therefrom, a felly, va U-shaped frame secured to the extremity of each spoke, a pair 01": cushioning blocks secured Within each of the U-shaped frames, said blocks extending beyond the frames and engaging the telly, stop members carried by the felly and projecting between each pair of blocks to prevent a circumferential movement of the telly relative to the spokes, and

side plates rigid with the spokes and extend ing outwardly into engagement with the sides of the cushioning blocks and felly.

2. A spring 'Wheel including a hub, a plurality of spokes, a telly, blocks positioned between the spokes, a plurality of springs engaging said blocks and felly, a pair of cushioning blocks secured to the outer end of each spoke and bearing against the telly, stop members carried by the telly and projecting between each pair of cushioning blocks for preventing a circumferential movement of the felly relative to the spokes, and side plates secured to said spokes.

In testimony whereof we affix our signatures in presence of two witnesses.
