Improvements in and relating to Wheels for Vehicles.
I, HOWARD MALCOLM DUBOIS, of 621 Susquehanna Avenue, Philadelphia,
Pennsylvania, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
lescribed and ascertained in and by the following statement :-
My invention relates to vehicle wheels having an elastic cushion, which is interposed
between the tire and felloes of the wheel, the tire being upset, and adapted to engage
with the centre and sides of said cushion, by which provision the tire may be firmly
nd securely seated on the cushion.

Improvements in and relating to Wheels for Vehicles.
I, HOWARD MALCOLM DUBOIS, of 621 Susquehanna Avenue, Philadelphia,
Pennsylvania, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
My invention relates to vehicle wheels having an elastic cushion, which is interposed
between the tire and felloes of the wheel, the tire being upset, and adapted to engage
with the centre and sides of said cushion, by which provision the tire may be firmly
and securely seated on the cushion.
In the accompanying drawing
Figure 1 represents a side elevation of a tire, embodying my invention.
Figure 2 represents a perspective view thereof, on an enlarged scale, on line xx,
figure 1.
Figure 3 represents a transverse section thereof,
Figure 4 represents a perspective view, the parts being separated.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a portion of a felloe of a vehicle wheel, to which is screwed or otherwise
fastened the channelled plate B. C designates an elastic cushion which is interposed
between the tire D of the wheel, and said plate B, and having its inner peripheral
portion located within the side walls or flanges of said plate.
The outer periphery of the cushion C, has a circumferential groove E, and the inner
periphery of the tire is formed with a circumferential rib or tongue F, which enters
said groove; and the tire is further more formed with side flanges G, which project
inwardly and embrace the sides of the outer peripheral portion of the cushion C. The
tongue is wide and deep, whereby the thickness of the tire is centrally preserved.
When the parts are primarily located in position, the tire which is integral is upset,
whereby its diameter is reduced, and it thus embraces the cushion, and holds the latter
upon the plate B.
The tongue F entering the groove E, serves to compress the central portion of the
cushion to a certain, but uninjurious extent, and as said tongue is of semi-cylindrical
or bulging form, its tendency is to distend the outer peripheral portion of the cushion
in lateral direction, the same being however, resisted by the flanges G, and thus
confined within the same, whereby the cushion is held firmly and true between the
plate and tire, and the latter remains seated on said cushion in a secure and reliable
manner, the general elasticity of the cushion being preserved.
The side flanges G are rounded, and embrace the rounded and contiguous portions
of the cushion C, and as the groove E is of semi-cylindrical form, or nearly so, to
accord with the shape of the tongue F, there is no cutting action of the tire upon the
cushion, it being noticed that angles on the inner periphery of the tire are avoided by
the construction presented.
If desired, the plate B may be an integral portion of the felloe, instead of a separate
piece, as shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. A vehicle wheel having a channelled plate secured to the felloes, a tire and
an elastic cushion between said plate and tire, the tire being upset, and all parts
operating substantially as described.
Second. A vehicle wheel having a channelled plate a tire and an elastic cushion
between said plate and tire said tire having a central tongue which enters a groove in
the cushion, the tire being upset, substantially as described.

Third. A vehicle wheel having a channelled plate, a tire and an elastic cushion
between said plate and tire said tire having a tongue which enters the cushion, and
flanges which embrace the same, the tire being upset, substantially as described.
Fourth. A vehicle wheel baving a channelled plate, an elastic cushion therein, and
a surrounding tire the latter being provided with a semi-cylindrical tongue which
enters a semi-cylindrical groove in said cushion, and flanges which embrace the sides
of the same, said tire with its tongue and flanges being upset, the parts being combined,
substantially as described.
