RESILIENT WHEEL.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Application filed. January 22, 1917. Serial No. 143,725.

To all whom it may concern:

Be it known that I, MACK H. HARRIs, a citizen of the United States, residing at Higginsville, in the county of Lafayette and State of Missouri, have invented certain new and useful Improvements in Resillent Wheels, of which the following is a speclfication, reference being had to the accompanying drawings. 1 This invention relates to certain improvements in resilient wheels and has relation more particularly to a device of this general character wherein a cushioned hub is employed; and it is an object of the invention to provide a device of this general character having novel and improved means whereby the shocks or jars incident to the travel of the wheel is substantially entirely eliminated.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved resilient wheel whereby certain important advantages are attained andthe device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will hereinafter be more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be better ,"understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a fragmentary view in side elevation of a wheel constructed in accordance with an embodiment of my invention with a removable flange comprised in the hub structure removed and a portion shown in section, the flexible shield being omitted;

Fig. 2 is a sectional view taken through the hub portion of the wheel as herein embodied; and

Fig. 3 is a view in perspective of one of the resilient members as hereindisclosed.

As disclosed in the accompanying drawings, 1 denotes a tubular member or sleeve comprised in my improved hub and which has integrally formed at one end portion the annular flange 2. The flange 2 is provided with an annular shoulder 3 with which a brake band may coact. The opposite end portion of the sleeve or tubular member 1 has in threaded engagement therewlth the removable flange 4 which is maintained in applied position through the medium of the set screws 5 as particularly illustrated in Fig. 2. r

Positioned between the flanges 2 and 4 and capable of movement independently thereof is the annular member 6 from which radiate the spokes S. The opposed walls or faces of the tubular member or sleeve 1 and the annular member 6 are provided with the circumferentially spaced recesses 7 into which extend the opposite end portions oftheresilient or spring members R.

Each of the members R consists of a strip of resilient material substantially V-shaped in form and'having its outer. or free end portions returned, as at 8, to aiford barrels through which are directed the removable pins 9 which are supported by the portions of the tubular member or sleevel and the annular member 6 adjacent the recesses 7.

The apex portion of each of the members R is so bent as to afford a barrel 10 through which is directed a pin 11 and, as is particularly illustrated in Fig. 3, the central portion of the barrel 10 is intersected by a slot 12 so that the coil springs 14 may be readily engaged with the apex portion of the member. The barrels 8 are also intersected by the slots 15 so that the opposite ends of the springs 14: may be engaged with the pins 9.

The tension of the members R and the springs lt is such as to maintain the annular members 6 substantially concentric to the tubular member or sleeve 1 when the wheel is free of load, but it will be perceived that upon travel of the wheel the members E and springs l l will permit such relative movement between the tubular member or sleeve 1 and the annular member 6 as to substantially entirely absorb all shocks and jars incident to the travel of the wheel.

I also find it of advantage to bridge the space between the flanges 2 and 4 by the flexible member 16 of leather or other suitable material and which has its opposite marginal portions reinforced by the wires 17 or the like so that the member 10 may be readily maintained in applied position. It is also to be noted in Fig. 2 that the spokes S are adapted to freely pass through the members 16. By having the members 16 of flexible material it will be at once selfeviden tfithat saidflmenibers' 16 will offer no obstruction to the relative movements of the tubular member or sleeve 1 and the annular member 6.

5 From the foregoing description, it is thought to be obvious that a resilient Wheel constructed in accordance With my invention is ofan extremely simple and comparatively inexpensive 'nature and is particularly well" adapted for use by reason of the convenience and facility with Which it may beassembled,

" and' itwi l'l also'beobvi'ous that my invention is} susceptible of some chan e and: modificati'on' Without material departure from the 0 principles and spirit thereof and for this hinges and capable of movement relative to the tubular member,- a substantially V- shaped resilient member interposed between the tubularm mber' the annular iireni \Ghpi es of mspatent' may be obtained for ter, the free endportions'and the apex portion of said resilient member being provided with r a barrel, a pin removably insertible within the tubular me'mb'er and through the barrel atthe' inner end of the resilient mem her, a pin removably insertible through the member and through the barrel at theouter end of the resilient member, pin disposed through the barrel at the" apex: portionof the member, each of said barrels being provided With a cut-out portion, a (301].

spring engageable With thepi-n at the apeX per-fisher the resilient member-"at the cut out portioa of the-adjacent barrel and with the pith coasting with the inner end portion of the resilient member at the' cut-out po'rti'orr at said 1nner'harre1gand a coil s ring 7 interposedbetween the pin at the? apex por tier-rotthe resilient member at the cut-out portion of said barrel and with the pin at c the outer end of th e resilient member at the cut-'oiit portionoi said; outer barrel.
