Improvements in Car Wheels.
I, JOHN JEMUSS CILLEY, of South Deerfield, Rickingham County, New Hamp-
shire, United States of America, Farmer, 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 car wheels. The object of my invention is to provide
a car wheel in two sections to facilitate the renewal of the wheels when worn out
er broken.
As at present done, the wheels are made in one piece, the hub is bored out to
a tight fit for the axle, and the wheel is then forced into the axle with a hydraulic
pressure, varying from 30 to 50 tons; consequently when the wheel is to be
renewed, it has to be forced off in like manner, which can only be done by
removing the axle and wheels from the car, and in many cases sending it away
to the original maker or to some shop equipped with hydraulic presses. This
entails the loss of the use of the car, the transportation charges on wheels and
axle going and returning, the expense of the work, and also the labor necessary
to remove it from and replace it beneath the car.
Under my invention this expense will be saved, as I shall make the car wheel
in two sections, viz. a flanged hub or central portion of the wheel, and the body
of the wheel or outer portion, The hub will be placed on the axle in the custom-
ary manner; the body of the wheel will then be put in place on the hub and
securely bolted thereto, using chock nuts to prevent loosening of the bolts. To
prevent any shearing strain on the bolts, suitable projections are provided on the
body of the wheel, which fit into corresponding recesses in the hub. To prevent
the bolts from turning around when the nuts are being tightened, the bolt holes
on the body of the wheel will be recessed, to take the heads of the bolts.
In renewing the wheel, all that it is necessary to do is to remove the bolts
attaching the body of the wheel to the hub, take off the body of the wheel, put on
the new one, and replace the bolts. As this can be done in a short time, the uso
of the car is not delayed to any extent.
To facilitate this quick renewal, the fit or joint between the body of the wheel
and the hub should be a taper one.
In the accompanying drawings-
Figure 1 is a perspective view of a car wheel constructed in accordance with my
invention;
Figure 2 is a similar view, the body and hub of the wheel being shown separated;
and,
Figure 3 is a sectional view.
In said drawing, 1 denotes the car wheel, formed with a tapering aperture 2,
about which the body of the wheel is enlarged as shown at 3, and provided with
projections 4.
5 denotes the hub, which is secured to the axle 6 in the usual manner, and
which is provided with a tapering portion 7 and an annular flange 8 having
recesses 9 to correspond to the projections.

through the annular flange and through the thickened portion of the body of the
wheel, and serve to prevent the lateral displacement of the body of the wheel with
respect to the hub.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
1. A car wheel composed of a body portion and a hub, the former being pro-
vided with a central tapering aperture with an integral annular shoulder surround-
ing said aperture and provided with projections and bolt holes and the latter
being tapering in form and adapted to the central aperture, and provided with an
annular Hange having recesses adapted to receive the projections of the body por-
tion, and bolt holes registering with the bolt holes of the body portion, and bolts
passing through the annular flange of the hub and the annular shoulder of the
body of the wheel, substantially as set forth.
2. In combination with the body of a wheel or outer portion having projections
about a central aperture, of a hub having a portion adapted to fit said aperture,
and provided with an annular flange having recesses adapted to receive projections
and bolts passing through the annular flange and the body of the wheel, together
with an axle to which the hub is attached, for the purpose set forth.
