We, JAMES HOWARD, EDWARD TENNEY BOUSFIELD and GEORGE GIBBS, all of
Bedford, in the County of Bedford, Engineers, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to wheels chiefly designed to be used as travelling wheels on
mowing, reaping and other harvesting machines. Our improved wheels aro, however,
applicable for other purposes.
The main driving wheels of harvesting machines are usually constructed in such a
manner that in turning the machines at the corners of a plot of grass or other crop
being cut they drag or cut up the surface of the ground.
According to our said invention we construct the rim of the wheel of U or channel
shape in transverse section, so that flanges are formed at the sides of the wheel, which
flanges serve the same purpose as the sides of the felloes of a wooden wheel. These
flanges also serve to strengthen the wheel.
The rim of our improved wheel is stamped in segments from plates of steel or
other suitablò metal, two or more of such segments being afterwards rivetted or joined
to form the complete rim; or is rolled to the proper shape.
When ribs or biting pieces are required on the periphery of the wheel the metal of
the rim is sometimes pressed outwards from the inside instead of attaching separate
strips or pieces thereto.
The spokes and hub of the wheel are attached to the rim by rivetting or in any
other convenient manner.
By this construction we are enabled to produce a light, strong and effective travelling
wheel.

Improvements in Wheels for Use on Harvesting Machines and for
other Purposes.
We, JAMES HOWARD, EDWARD TENNEY BOUSFIELD, and GEORGE GIBBS, all of
Bedford, in the County of Bedford, Engineers, 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:-
Our invention relates chiefly to the main driving wheels of harvesting machines.
Our improvements are, however, applicable to wheels, drums or pulleys for various
other purposes.
The driving wheels of harvesting machines, as heretofore constructed, are dis-
advantageous for the reason that, in turning the machine at the corners of a plot of
grass or other crop being cut, the said wheels are liable to drag or cut up the surface
of the ground. One object of our present invention is to obviate this defect.
We construct the rim or tire of our improved wheel of a channelled or U shape in
transverse section so that flanges are formed at the sides of the wheel, which flanges
serve the same purpose as the sides of the felloes of a wooden wheel. These flanges
also serve to strengthen the wheel.
In the accompanying drawings
Figure 1 is a front elevation of a driving wheel for a harvesting-machine made in
accordance with our said invention.
Figure 2 is a section on the line a, a, Figure 1.
Figure 3 is a front elevation illustrating a modification of our improved wheel, and
Figure 4 is a section on the line y, y, Figure 3.
A is the nave or hub of the wheel. B is the rim or tire which is made with the
flanges b. C, C are the spokes.
When ribs or biting pieces are required on the periphery of the wheel, we some-
times attach thereto separate pieces or strips of metal as shown in Figures 1 and 2.
In other cases, the metal of the rim is embossed or pressed outwards from the inside,
as shown at 6 in Figures 3 and 4, to form the said ribs or biting pieces.
Our improved wheels may be manufactured with advantage according to either of
the following methods, viz. :-
(A) Segments of the rim or tire of the wheel are stamped or pressed to the required
shape and afterwards bolted or rivetted together with strips inside, the segments of
the wheel being laid upon the spoke-ends and afterwards attached thereto, and the
whole finally rivetted together.
(B) A flat plate of the dimensions required to form the rim or tire is first welded
to form a ring, then, by swaging or otherwise, the edges of the plate are flanged over
to produce the channel-shaped rim or tire. When the wheels are thus made with an
endless tire, the spokes C may be curved and introduced as shown by the dotted lines
in Figure 2. The spokes are then straightened and rivetted to the flanges and sole of

page_text: the wheel as shown in full lines in Figures 1 and 2; or the spokes may be fixed in
any other approved manner.
(C) Our improved wheels may also be formed by a similar process to that adopted
for railway-tires from a billet which is rolled continuously as a ring until the required
size and shape are attained. The spokes are then introduced and fixed as in the method
hereinbefore described and lettered B.
By the above described improvements we are enabled to produce a light, strong
and effective travelling wheel.
It is obvious that our improvements can be advantageously applied to wheels, drums
or pulleys for driving machinery and for other purposes.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we wish it understood
that we claim :—
First. A travelling wheel, drum or pulley constructed as herein before described
with a wrought metal rim or tire which is channel-shaped in transverse section.
Second. The manufacture of travelling wheels, drums or pulleys substantially
according to the method herein before described and lettered A.
Third. The manufacture of travelling wheels, drums or pulleys substantially
according to the method hereinbefore described and lettered B.
Fourth. The manufacture of travelling wheels, drums or pulleys substantially
according to the method hereinbefore described and lettered C.
Fifth. A travelling wheel having ribs or projections embossed or otherwise formed
out of the plate metal of the tire as above described, and as illustrated in Figures 3
and 4 of the drawings.
