RESILIENT WHEEL.

Application filed July 30, 1913.

, To all whom it may concern:

Be it known that Ltlnvnn ITLIPARKER, a citizen of the United States, residing at Garden City, in the county of Cass and State of Missouri, have invented certain new and useful Improvements in Resilient Wheels, of whichthe following is a specification.

This invention relates to that type of resilient wheels in which an annular pneumatic cushion is arranged between the rim and hub portions of the wheel to provide an intermediate resilient connection between the parts. And the present improvement has for its object to providea simple and efficient structural formation and arrangement of parts whereby the same can be removed, repaired and replaced without injury to the remainder of the wheel.

A further object of the invention is to provide means in the nature of a plurality of yieldably supported spokes mounted for reciprocatory movement in a sleeve provided therefor, the latter being pivotall y connected to the hub and the spokesbeing pivotally connected to the rim, this arrangement yieldably supporting the hub and rim in such a novel and peculiar manner as to absorb the shock occasioned by the travel of the wheel over inequalities in the road or other sur face.

A still further object of the invention resides in the provision of means including a plurality of guide members disposed for engagement with the pneumatic cushion to act as an abutment for the spokes during their reciprocatory movement.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the appended claims forming a part of this application.

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views and in which Figure 1 is a side elevation of a wheel constructed in accordance with my invention; Fig. 2 is an enlarged sectional view of a portion of the wheel; Fig. 3 is an enlarged section on the line 3-3 of Fig. 2; and Fig. 4, is a detail perspective view of one of the guide members.

Proceeding now to the description of the Specification of Letters Patent.

drawings wherein. is illustrated the preferred embodiment of my invention, the numeral l designates the wheel hub having a plurality of uniformly spacedapart lugs 2 projecting from. the periphery thereof adjacent each edge of the hub, the said lugs serving as a support or means to which the forked ends 3 of the sleeves at are pivotally secured as at Spokes 6 radiate from the axis of the hub 1, the inner end of each spoke engaging the head 7 of a guide member 8, the said member comprising, in addition to the head 7, a pair of oppositely disposed parallel strips 1 9, the said strips fitting within dove-tailed grooves 10 formed within the sleeves at, one upon each side thereof, this arrangement of the guides S with respect to the sleeves -l permitting the spokes (l to slide independently of the sleeves, the strain and weight being received by the head 7 of the guide members.

The spokes 6 are exteriorly threaded as at 1.1 intermediate the ends thereof over which.

a lock nut 12 is arranged to permit adjustment and thereby limit the reciprocatory movement of the spokes with respect to the sleeves, the engagement between the outer extremity of the sleeves with the under face of the nut preventing excess movement of the spokes or hub during the travel of the wheel over uneven surfaces. The opposite end of the spoke from. that abutting the guide member 8 is pivoted as at 13 to cars 14.- projecting from the inner periphery of the rim 15, which pivotal connection, taken in conjunction with the pivotal connection shown;at 5 allows the spokes and sleeves 4.- to move laterally as occasion demands.

To receive and absorb the shock occasioned by the movement of either the hub 1 or the spokes (3, an annular pneumatic tube or tire 16 isinterposed between the guide members 8 and the hub 1, a portion of the tube fitting within an annular recess 17 formed within the said hub. The forked ends of the sleeves 4 are so disposed with respect to the tire or tube 16 as to straddle the same and thus act as a fastening means therefor; the engagement between the guide members 8 and the said tubular member preventing displacement of the latter from engagement with the hub 1.

In the practical application of the invention, the strain upon the rim 15 is received and absorbed by the annular tube or tire 16 as the spokes 6 are so disposed with respect to the rim as to be entirely supported by the tire, the latter acting as a cushion therefor. By this arrangement, the usual wear and tear attending a tire is completely obviated, and the longevity thereof materially. increased.

It will be seen from the above, taken in connection with the accompanying drawings, that the resiliency of the wheel is limited only by the adjustment of the lock nuts 12' upon the threaded portion 11 of the spoke; that the guides S are arranged with respect to the sleeves 4 in such a novel and peculiar manner as to prevent rotation of the former and displacement of the head 7 from beneath the lower extremities of the spokes; and that the tire or any one of the several embodiments comprising my invention, may be removed, repaired and replaced without necessitating the displacement of the other of the several parts.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above'description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when=required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a resilient wheel, a hub, a pneumatic tire encircling the hub, means pivoted to said hub, said means forming retainingelements for said tire, a rim, spokes pivoted to said rim and engageable with said retaining elements, the latter forming guides therefor, and means engageable with said tire and'said spokes to yiel'dably support the latter, as and for the purpose set forth.

2. In a resilient wheel, a pneumatic tire encircling the hub, a plurality of radially arranged sleeve-like members with forked ends pivoted to said hub, the forked-ends of the said members providing retaining elements for the said tire,a rim, spokes pivoted tosaid rim, said spokes reciprocating within said members, and means engageable with said members and with said. tire against which the said spokes abut, said means forming yieldable supports for said spokes, as and for the purpose set forth.

3. A resilient wheel including a hub, a pneumatic tire arranged over the periphery of the said hub, a plurality of sleeves pivotally secured to the said hub, the said sleeves being provided with forked ends adapted to straddle the said tire to retain the latter upon the said hub, guide members carried by the said sleeves disposed for engagement with the said tire, and a plurality of spokes eXtending't-hrough the said sleeves and yieldably' supported by engagement with the said guide members, as and for the purpose set forth.

4-. A resilient wheel including a hub, a plurality of sleeves with forked ends pivotally secured to the said hub, an annular pneumatic tube arranged upon the periphery of the hub between the forked ends of the said sleeves, the said forked ends acting as fastening means therefor, guide members yield'ably supported upon the said tube, the said guide members being provided with parallel strips adapted to fit within grooves formed in the sides of the said sleeves, a

wheel rim, aplural'ity of spokes pivotally secured to the said rim adapted to extend through the said sleeves, the inner ends of the spokes being yieldably supported by engagement with the said guide members, and means including a lock nut threaded upon each of the said spokes to limit the movement thereof, as and for the purpose set forth.

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