Improvements in Wheels and Pulleys.
We, EDWARD EMANUEL JOSEF, of 188 Virginia Street, Buffalo, in Erie County
and State of New York, Mechanical Engineer, JOHN LAUGHLIN, of 487 Pearl

HouPT of 264 Summer Street, all of Buffalo, in the County of Erie, and State of
New York, Attorneys and Counsellors at Law, and all in the United States of
America, 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
ollowing statement :—
Our invention consists in certain improvements in wrought metal wheels whereby
great strength, durability and other advantages are obtained, and it will be fully
and clearly hereinafter described.

The object of my invention is to produce a locomotive or car wheel that will
combine great strength and durability combined with lightness and truth of balance
and consequently be not liable to break or otherwise get out of order.
In said drawings, the hub of the wheel, it will be seen, is composed of two parts,
1 and 2, see Figures 2 and 3, also Figures 9 and 10, on Sheet 2.
The part 1, of the hub is provided with a portion 3, of reduced diameter adapted
to be fitted nicely in the recessed portion, 4, of the opposite part 2, of the hub so
that when the two are put together they form a hub substantially as shown in
Figures 12 and 3.
On the inner side of each portion of the hub is a series of projecting sleeves, 5,
see Figures 13 9 and 10, the object of which will more clearly hereinafter appear.
This hub is preferably made of steel casting but malleable iron or other suitable
material may be used.
A modification of the hub is shown in Figure 11, in which it will be seen that
one part of it is provided with a reduced portion 6, that extends the full thickness
of the hub and the other part, 7, is bored out sufficiently large to fit closely
over it.
The inner supporting ring 8, is adapted to fit around the inner portion of the

page_text: wheel near the hub and is provided with a series of depressions, 9, corresponding
in size with the sleeves, 5, which fit nicely into them when the wheel is together.
In Figure 6 we have shown a modification of this inner supporting ring having
projecting sleeves, 5 thereon instead of the depressions, 9. In this case the
sleeves, 5, on the hub would be dispensed with, and in their place a corresponding
series of holes would be provided to receive the sleeves 5", either construction will
answer the same purpose.
The body of the wheel is composed of two discs 10 and 11, see Figures 4-8
and 9 also the sectional views Figures 1, 2 and 3.
These discs are formed preferably of sheet steel for a car wheel from one quarter
to one half inch thick, more or less, but for other wheels other thicknesses can be
used, they are either stamped up into shape in suitable dies or formed by a
flanging machine, and each are provided with a central flange 12, which surrounds
the hub.
At the periphery of each of these discs is another Hange 13, the construction
being such that when the two discs are put together the edges of the flanges meet,
substantially as shown in Figure 4.
Around the central flange 12, is a series of holes, 14, to receive the sleeve 5 or 5".
Between the hub flanges, the body of the hub, the discs 10 and 11 and the
central flanges 12, is interposed a thin layer of asbestos or other similar
material, 15, to relieve the several parts from the concussion incident to said
road service.
I also place a layer of similar material, 15, between the inner sides of the discs
and their flanges 12, and the central supporting ring.
The object of this construction is to provide the means for absorbing the con-
cussion incidental to and created by the running of wheels over railroad tracks,
especially where the ends of the rails abut together and by this means prevent the
concussive blows from being transmitted through the wheel and hub to crystallize
the axle thereby rendering it liable to break and cause accidents.
The tyre, 16, see Figures 12 and 7 is made of the usual material rolled steel and
is provided with an inner flange 17, projecting toward the centre and an outwardly
projecting flange 18.
Above the flange, 18, is a depression 19, which allows the flange, 18, to be turned
over more easily when completing the wheel.
The construction permits the wheel, after being secured together as shown in
Figures 1 and 2, by the bolts, 20, or by tubular rivets 21, shown in Figure 3 to be
slipped in into the tyre, passing in the direction of the arrow V, Figure 2.
After the tyre is thus put in place, by shrinking in the usual and well known
way, both flanges are forced over close to the disc so as to bring them rigidly in
place substantially as shown in Figure 1, thereby completing the wheel.
It will be noticed that both sides 22, of the periphery of the wheel project
outward beyond the portions 23, so that even if the tyre should become broken, it
could not come off.
From this construction it will be seen that the tyre of the completed wheel is
formed with two flanges on the inside edges, both projecting toward the centre of
the wheel, the object of which is to give strength to and stiffen the tyre so as to
allow it to be worn thinner in the tread allowing more service of the tyre before
being discarded and a new one to be placed on the wheel, a further use of the tyre
flanges is the strengthening of the wheel by being turned down over the peripheral
edges and sides.
The object of the annular depression or groove, 19, in the side of the tyre is to
lighten it and also to allow the flange 18, to be more readily bent or flanged down
over the edge and side of the wheel to thoroughly hub and embrace it.
The annular groove 19, surrounding the flange 18, is an important element
because the flange could not be practically turned down over the edge 22, without
it, so as to hug it closely over every portion over which it fits, as it will be readily

page_text: seen the groove practically lengthens the flange so that it can be more readily
turned over the edge of the wheel.
In Figures 13 and 14, I have shown a slight modification of the wheel adapting
it for use as a pulley. The two discs 10 and 11, are both provided with an
inwardly projecting peripheral flange 13. The central portion 24, of the hub is
provided with two side flanges 25, all preferably formed in one piece, as shown in
Figure 13.
The discs 10 and 11, are also cach provided with a hole through which the shaft
passes, the hub portion 24, being first put on, and then the discs on each side of it,
the two hub discs, 26 and 26", are then put on substantially as shown.
The hub disc, 26, is provided with a series of sleeves 27, with central holes
through which the bolts 28 pass and the disc 26" is also provided with a corre-
sponding series of sleeves 27, each having a screw hole into which the bolts 28, are
screwed, and as the bolts each pass through corresponding holes in the side 10
and 11, the whole are thereby rigidly secured together.
When a narrow faced wheel is used the central hub portion should be made to
allow the flanges 13, to come together as shown in Figure 4, but when a wider
faced wheel is desired we insert an intermediate rim, 29 see Figure 13. This rim
it will be seen is raised in the centre so that it projects up between the flanges 13,
so as to be even with the face, and the side portions 30, project inside of the
flanges 13, thereby forming a strong central support for the pulley shown in
Figure 13.
The same side discs may be used for any width of pulley, the only change required
being in the width of the rim 29, and the central hub portion 24.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
First. The combination of a double inwardly flanged tyre for holding the wheel
together and the tyre rigidly in place, two sheet metal discs having flanges
projecting inward so that their edges meet when the wheel is completed, a hub
formed in two parts provided with a series of inwardly projecting sleeves, which
pass through holes in the discs, an inner supporting ring provided with a series of
depressions on each side corresponding with the sleeves on the opposite sides of the
hub into which the sleeves project when the several parts are in place, and bolts
for securing the discs and inner supporting ring to the hub, substantially as
described.
Second. In a wheel the combination therewith of a tyre provided with flanges 17
and 18, on its opposite inner edges the flange 18, projecting outward, and an
annular groove 19, surrounding the flange 18, substantially as and for the purposes
described.
Third. A car wheel consisting of two discs, each disc having a peripheral
flange 13, and a central flange 12, so that when the two discs are put together the
edges of the flanges meet and form a wheel, a tyre surrounding said discs and
having two flanges projecting inward from its inner edges one flange having a
groove, 19, surrounding it, for clasping over and holding the peripheral flange and
their discs rigidly together, and a divided hub and bolts or tubular rivets for
securing the central flanges firmly together, substantially as described.
Fourth. In a wheel the combination of two discs each provided with a central
and a peripheral flange both flanges projecting inward so that the edges of the
opposite flanges will meet when the wheel is put together, and bolts for securing
the discs to the hubs, substantially as described.
Fifth. In a wheel the combination of a hub consisting of two parts, one part
overlapping a reduced portion of the other, an inner supporting ring surrounding
the hub, two concave double flanged discs forming the body of the wheel, a means
for securing them to the hub substantially as specified and a tyre provided with

page_text: two flanges on its two inner opposite edges projecting inward toward the centre of
the wheel and toward each other substantially as and for the purposes described.
Sixth. A compound hub for wheels consisting of the part 1 provided with a
reduced portion 3, and having a series of sleeves, 5, by which it is secured to the
body of the wheel, in combination with the portion 2, having the recessed portion 4,
to receive the reduced portion 3, of the part 1 and a corresponding series of
sleeves 5, through which the bolts pass for securing it to the body of the wheel,
substantially as described.
Seventh. In a wheel, the combination of two side discs each provided with an
inwardly projecting flange, a central peripheral rim for increasing the width of the
pulley and fit in between the inwardly projecting flanges, a central hub portion
interposed between the discs and provided with side flanges each having a series of
holes, side hub discs having sleeves adapted to fit in said holes and both adapted to
pass through the sleeves and secure the whole rigidly together, substantially as
described.
