Improvements in Wheels for Traction and other Road Engines
I CHARLES BRAMALL of Caledonian Works Oughtibridge near Sheffield in the
County of York Manufacturer do hereby declare the nature of this invention to
be as follows:-
My invention relates to certain new and useful improvements in the construction
of wheels for traction and other road engines, whereby I overcome the objections
there are to wheels made of cast iron, and I improve the adhering and traction
power of the wheels, and greater durability of the tyres or rims thereof is attained.
My improvements are chiefly applicable to the construction of new wheels for new
traction engines, but my invention can also be applied to wheels of existing or old
traction engines.
In my improved wheel, when making a new wheel, I construct the tyre or outer
rim preferably of steel the thickness of which will be generally from about five
to about eight inches deep.
I make the wheel in the ordinary way with a tyre or outer rim as usual, to
which I add another rim of from about three to about six inches deep, this rim
also is made of steel and has made therein a suitable number of recesses or openings
for blocks of wood, iron, or steel, (which I propose to make of a hexagonal shape by
preference) and I have another rim of about half an inch thick and with recesses or
openings of smaller diameter in order to keep the blocks from falling out of place in
the middle rim.
The blocks are each constructed with a projecting notch all round the base, or on
the sides as required, the remaining portion of the block is made parallel. When a
block becomes worn on the top or wearing part the outer plate or plates of the tyre
or rim, when it is inade in seginents, can be removed and the ring or packing which
is provided to keep the block in position can also be removed so as to allow the block
(or blocks) to be elevated or raised up by placing, say, a block of wood or of some.
suitable elastic material under the base of the block (or blocks).
The outer and inner rims of the wheel I make either in one solid piece of steel, or
in segments when so required.
I can make the blocks either of hexagonal, oircular, or other suitable shape, and I
place them in two three or more circumferential rows around the tyre or rim of the
wheel. I make them either of steel iron or wood as required, but when made of
wood I surround or encase the wood in a shell of steel, made either with a notch or
projection at the base, or the blocks can if necessary be made in the form of a cone,
but either is to be so made as to keep the blocks from falling out of their positions,
and they will be so secured as not to interfere with their proper working in the
recesses.
When adapted or required for old or existing traction wheels the rims are made in
sections and so applied to the wheels.

Improvements in Wheels for Traction and other Road Engines,
I CHARLES BRAMALL of Caledonian Works Oughtibridge near Sheffield in the
County of York 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 in writing, and on reference to the
accompanying sheets of drawings :
My invention relates to certain new and useful improvements in the construction
of wheels for traction and other road engines, whereby I overcome the objections
there are to wheels made of cast iron and I improve the adhering and traction power
of the wheels, and greater durability of the tyres or rims is attained.
My improvements are chiefly applicable to the construction of new wheels for new
traction engines but my invention can also be applied to wheels of existing or old
traction engines.
In order that my improvements, and the best means I have adopted in carrying out
my invention in practice, may be fully understood, I have illustrated the same on the
accompanying three sheets of drawings which are marked with Figures and letters of
reference corresponding with those in the following description, the same reference
letters indicating similar parts in all the Figures.
Figure 1, Sheet 1, is a side elevation of a new traction engine wheel of ordinary
pattern with my improvements applied thereto.
Figure 2, represents the outer surface of part of my improved rim or tyre when
applied to an old or to an existing wheel, and containing the recesses or openings
and bolt holes; but when made for new wheels the bolt holes are not made therein.
Figure 3, is a section drawn on the line A-A in Figure 2, showing the tyre
attached to an ordinary traction wheel.
Figure 4, Sheet 2, shows an iron or steel casing, shell, or box, before a wood or
other block is inserted therein.
In Figure 5, which represents a part only of my rim or tyre, B is an iron or steel
casing, shell, or box, placed in position but without a block therein. C, shows a
casing with a wood block therein. D, shows in elevation a casing, shell, or box, in its
recess or socket. E, shows in elevation a casing shell or box in its recess or socket,
when under pressure.
Figure 6, Sheet 3, which is drawn partly in section, shows a convenient method of
connecting my improved rim or tyre to a new wheel, when made with two rims or
tyres.
In the above Figures, a, is the outer rim or tyre of the wheel, b, the ordinary tyre
of the wheel, to which the rim a, is bolted in old wheels, but in new wheels a, and b,
are made in one casting-c, (Figure 3) shows the recesses or sockets in the
outer rim or tyre a, to hold the casings or shells or boxes d, (Figures 4, and 5).
e, (Figure 5,) is a wood block as inserted in a casing or shell or box.f, is the wood
or elastic material fitted under the casings or shells or boxes.-y, is a bolt to secure
the casings or shells or boxes in position.-, represents spring washers or spiral
springs on the bolts g.
i, (Figure 6,) represents lugs, cast on the tyre at intervals to secure the two balves,
or outer and inner rims or tyres, together; or instead of lugs I can use strengthening
plates. j, (Figures 2 and 3) shows the bolt holes and bolts provided to secure the
outer rim or tyre to wheels as now usually inade. A, (Figure 6) is one of the
spokes of the wheel. , is the boss of the wheel, and m, is that part of the boss
through which the axle is passed, being shown in connection with the method of
connecting the rim or tyre to a new wheel.
In making a new wheel according to iny invention I construct the tyre or outer
rim a, of steel the thickness of which should be from about three to about eight inches
in depth.

page_text: This tyre or outer rim contains a sufficient number of recesses or openings or
sockets C,
for the casings or shells or boxes d, which are made of iron or steel, and by
preference of a hexagonal shape.
A block f, made of wood or of some other suitable elastic material is placed under
the base of the casings, shells, or boxes, so as to allow each casing and the block
therein to be raised up as required.
The outer and inner rims a, and b, of the wheel are made either of one solid piece of
steel all round, or in segments or parts when so required,-
,-as shown at Figures 3, 5,
and 6.
The casings or shells or boxes (, and the recesses or openings c, and the blocks, can
be made either of hexagonal, circular, or of other suitable shapes and are placed in
two, three, or more rows round the circumference of the tyre or rim of the wheel.
The blocks, such as the one shown at e, Figure 5, can be made either of steel iron
or wood as may be found necessary, and encased or not. They and the casings or
shells are held in position by a bolt g, being passed through a hole in the casing or
box d, and fastened with a nut g, and spring washer h.
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 :-
1. The construction, combination, and application of double rimmed or tyred steel
wheels specially adapted for new or old traction and other road engines, such rims or
tyres having cut or made in their circumferences a sufficient number of recesses or
openings or sockets in which blocks of encased or inetal framed wood, or blocks of
iron or steel, are inserted, and which work up and down; within which rin or tyre
an additional or inner rim or tyre is fixed, cut or made with smaller recesses or
opening, or holes arranged to hold and keep said blocks in position in the outer rim
or tyre; all substantially as hereinbefore specified, and as iliustrated on the accom-
panying drawings.
2. The construction combination and use of wood blocks encased in metal boxes or
shells or frames, or of metal blocks, the same being so arranged as to readily work up
and down in their respective recesses or openings or sockets during the revolving of
the wheels, substantially as herein before set forth and as illustrated on the accom-
panying drawings.
3. Making the said rims or tyres in sections or separate portions so that the same
can the more readily be applied and fixed into existing wheels of traction and other
road engines, substantially as herein before set forth, and as illustrated on the accom-
panying drawings.
