WHEEL.

Application illed March 11,

To all whom it may concern.'

Be it known that I, GUSTAVE Louis BOUR- QUIN, a citizen of the United States, and a resident of Sellersville, Bucks county, Pennsylvania, have invented certain Improvements in Wheels, of which the following is a. specification.

My invention relates to wheels; and the object of my invention is to provide a wheel suitable for use with automobiles and auto trucks that will have sufficient resiliency and yet avoidthe danger of puncture common with pneumatic tired Wheels. These and other features of my invention will be more fully pointed out hereinafter, reference bein had to the accompanying drawings, inv whic:

Figure 1, is a view in elevation, partly broken away,l showing a wheel embodying my invention; Fig. 2, is a sect-ional view on view of one of the springs which I may emplo Fig. 4, is a perspective view of a modi spring "arrangement embodying my invention, and Figs. 5 and 6, are views 1llustrating modified details within the scope of my invention.

In the wheel structure embodying my invention as shown in the drawings, I provide .a central element, which is substantially a wheel, comprising a hub l with a web 2 radiating therefrom and forming substantially what may be termed spokes; such web carrying a rim 3. In the present instance, this rim is provided with grooves or recesses 4 in its outer face for the reception of springs 5. In one embodiment of my invention these springs are of a somewhat peculiar shape, shown more clearly in the perspective view, Fig. 3, and comprise a lower, substantiall semi-circular portion 6, with curved leaves and 8 extending upwardly therefrom; the leaves 7 being in pairs while the leaves 8 are single and are disposed on the opposite side of the portions 6. In lieu of the use of springs of this character I may employ other forms of springs and in Fig. 4, I have showna plurality 0I single springs, set alternately in pairs and singly 1n the grooves or recesses 4 of the rim 3. The freerends of the springs bear against an annular wearplate 9 carried by an outer rim or felly 10, which is preferably of wood. This wearplate maybe loose or secured to the wooden Specification of Letters Patent.

are inclosed by a metallic shell 11 made in half sections, as shown; the outer flanged part of the same forming the tread of the wheel and overlying the wooden rim, and such shell may be secured to the wooden rim by screws 12. The shell structure is additionally secured together and to the wheel by means of bolts 15 and nuts 16; said bolts passing through apertures 17 in the web 2 whereby suilicient space is afforded to accommodate the various positionsV said'bolts will assume during use of the wheel. To prevent crushing the shell at the points where the bolts are employed, I preferably surround the latter with sleeves 18; the ends of which sleeves engage the Vinner Walls of the shell sections.

It is desirable to introduce oil into the spring chamber to reduce as much as possible the friction between the springs and t-he metal portions upon which they bear, and for this purpose I ma provide the rim 3 of the wheel with annu ar grooves 19 on both sides of the same and short grooves 20 leading from said annular grooves to the spring pockets or the surface of the rim 3. An a rture 21 may be formed in said rim, close by a plug 22; such aperture meeting a cross-bore 23 communicating with both of the annular grooves 19, as more clearly shown in Fig. 5. By this arrangement, oil or other lubricant in any desired quantity may be introduced into the spring chamber as desired, and such oil will be held by the side Walls of the shell forming the spring chamber against escape.

The metal shell forms the tread of the wheel, and is preferably substantially flat, as indicated, and of considerable width. I may, however, provide the tread of the wheel with a tire of rubber or similar material, and to this end the tread of the shell may be struck up at points to form ears 25 to engage a tire as 26,as shown in Fig. 5; ora lurality of tires, as shown in Fig. 6, bolts 2l) preferably passing through said ears and tire as indicated. This tire or tires may be of solid rubber or suitable equivalent material.

I claim:

1. The combination, in a wheel, of a central member comprising a hub, a felly and a suitable web integrally connecting the hub and felly, said felly having seats formed in its outer surface paralleling the axis of said The springs and wooden rim ofthe Wheel f portion, an

hub, an outer riln of wood, a plurality of independent and substantially unconlined springs substantially U-shaped in contour adapted to the seats in said telly, said springs having flaring ends disposed toward said'outer rim and interposed between the same and the telly of the central portion, a Wear plate carried by the Outer rim in engagement with said free ends of the springs, shells inclosing said outer rim and Lthe springs, means for securing said shells' to said outer rim, and bolts passing through the central member for securing said shells together, the web of said central member having enlarged openings Jfor the passage of the bolts, such arrangement providing for limited movement between said shells and the central member.

2. The combination, in a wheel, of a eentral member comprising a hub, a :telly and a suitable web connecting the hub and telly, said telly having seats formed in its outer surfacel paralleling the axis of said hub, an outer rim ot' wood, a plurality ot substantially U-shaped springs adapted to said seats, said springs having laring free ends disposed toward said outer rim and interposed between the same and the telly of the central annular Wear plate carried by the outer rim in engagement with said free ends of the springs, shells inclosing said outer rim and the springs, means for securing said shells to said outer rim, bolts passing through the central member for securing said shells together, the Web of said central member having enlarged openings for the passage of the bolts, such arrangement providing for limited movement between said shells and the central member, means for introducing a lubricant to fthe spring seats formed in the rim of the telly, the latter having annular oil grooves on both sides of the same and passages communicating be tween said oil grooves and the seats for the springs, and means for introducing oil into said grooves, the shells in substantial contact with the telly forming the outer Walls of said grooves and being also lubricated in their movement during use of the Wheel.

The combination, in a wheel, of a central member having a hub, a telly, a suitable web integrally connecting the hub and telly, said telly having seats formed on its outer surtace parallel with the axis of the hub, an outer rim ot wood, a plurality of substantially U-shaped springs/having free outer ends flaring from'their centrally connected portion interposed between the outer rim and said telly, the connecting portions of said springs being curved and resting in the seats ot said felly, a sectional shell inclosing said outer rim and the springs, bolts passing through the central member for securing sections ot the shell together, said central member having enlarged apertures for the passage of said bolts, such arrangement permitting movement of the shell with respect to the central portion, the telly of said central portion having annular oil grooves on both sides of the same and channels leading from said grooves to the seats or the springs, formed in said rim for the introduction of oil, an annular wear plate carried by the buter rim :tor engagement with the outwardly flaring ends of the springs, and means for removably securing said shell to the outer rim.

.ln testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
