CUSHION-TIRE.

Specificationof Letters Patent. Patented Dial, 15, 1921.

Application filed April. 17, 1920. SerialNo. 374,776. r

To all whom it may COWCGFII- Be it known that I,;T1 '3LESPI'IOI{E COHEAU, a citizen of the United States, residing at Lawrence, inthe county of Essex and State of lllassachusetts, have invented certain new and useful Improvements in Cushion-Tires: and I 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. 7

This invention relates to. new and useful improvements in 'cushion tires and has for its primary object the provision of cushion means adapted to fill a tire or shoe of the ordinary construction and efficiently sup port the same with the desired resiliency. thereby obviating the use of pneumatic means and themlisadvantages and expense attached to the latter named means.

Another object of this invention is the provision of inner and outer pads so shaped or constructed that they fully fill the casing or shoe when placed therein and have their opposing faces formed to provide a chamber for the reception of a cushioning means so that said shoe or casing is afforded the desired resiliency.

A further object of this invention is the provision of cushioning elements formed on one of the pads within said chamber and arranged in spaced relation to each other and. engaging the other pad to permit the'casing or shoe to flex when subjected to shocks and jars. thereby rendering the resiliency afforded by pneumatic cushion means without the annoyance of punctures and blowouts.

A still further object of this invention is the provision of a cushion tire of the above stated character which shall be simple, durable, and efficient, and which may be manufactured and sold at a comparatively low cost.

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

For a complete understanding of my invention. reference is to be had to the following description, and

accompanying drawing, in wh1ch:-

c Figure 1 is fa transverse sectional view .1

illustrating a cushion tire constructed in accordance with my invention,

--Fig. 2 is a sectional view taken on the line 3-3 of Fig. 1 looking in the direction indicated by the arrow,

Fig. Bis-a sectional view' taken on the line 2-2 of- Fig. l. I r Referring indetail to the drawing, the numeral 1. indicates a casingforshoe of an ordinary, construction and which. is usually employed in conjunctionfwith a pneumatic tube, and toobviatethe employment. of such,

I haye'provided inner and: outer pads 2 and 3 respectively, that are so shaped or constructed as to completely fill and engage the walls of the casing or shoe to efficiently support and prevent the same from collapsing under weight. The inner and outer pads extend circumferentially of the shoe or casing and are preferably constructed from fabric and rubber so as to have the desired elasticity. The opposing faces of the inner and outer pads have formed therein circumferentially extending recesses 4 that cooperate with each other in forming a chamber 5. The recesses t are cut away to form V-shaped portions 6 to the cushion receivingchamber 5 to'render an increased resiliency to the pads.

The outer pad 3 has formed thereon rela tively spaced cushioning elements or blocks 7 that form an integral part of the inner 1 wall of the recess 4 of said pad. The cushioning elements 7 are preferably constructed from a high grade of rubber and bear agamst the inner wall of the recess 4 of the pad 2 and are spaced from the side walls of the recesses 4t of the inner and outer pads permits said cushioning elements to expand and contract under shocks andjars subjected to the casing or shoe thereby afi'ording said casing or shoe the desired resiliency.

While I have shown and described the preferred embodiment of my invention it will be understood that minor changes in construction, combination, and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.

Having thus described-my invention, what I claim is 1. A tire cushion comprising inner and outer cushion sections adapted to have abutting engagement With each other and the wall of a shoe, said sections extending circumferentially of the shoeand having continuous recesses located in their opposing faces and cushioning blocks formed on the inner wall of the recess ofthe outer section andbearing against the inner Wall of the recess of the inner section.

2. A tire cushion comprising inner and outer cushion sections adapted to have abut ting engagement with each other and the wall of a shoe,saidsections extending circumferentially of the shoe and having continuous recesses located in their-opposing faces, and tapered cushioning blocks formed on the inner Wall of the recess of the outer section and bearing against the inner wall of the recess of the inner section and spaced fromthe side walls of said recesses.

3. A tire cushion comprising inner and outer sections adapted to have abutting engagement with each other and to entirely fill a shoe, s'aid sections extending circumferentially of the shoe and having continuous recesses located in their opposing faces.

and in alinement with each other, said recesses having their adjacent edges cutaway and adapted to cooperate with each other in increasing the areas of said recesses, and

' cushioning blocks formed on the inner wall of the recess of the outer section and bearing against the inner Wall of the recess. of the inner section.

In testimony whereof I my signature in presence of two witnesses. 7 o
