Improvements in Wheels for Railway and other Vehicles and in
Pulleys.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, 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:-
:-
This invention relates to that class of wheels and pulleys in which the sides of the
said wheel or pulley are thrust radially against the rim and the said invention consists
partly in the manner of constructing the interior portion of the wheel or pulley and
partly in the manner of uniting the interior portion with the rim, substantially as is
hereinafter set forth.
The invention is applicable to varions forms of wheels and pulleys. It is especially
adapted to wheels for railway and other vehicles.
In the accompanying drawing
Figure 1 is a view showing the improved wheel partly in elevation and partly in
central section and the parts within the rim being shown as they are before the parts
of the web are closed together and against the rim.
Figure 2 is a similar view but showing the web parts closed together and against
the rim as they would appear when the wheel is completed.
Figure 3 is a detail section drawn to an enlarged scale showing the relation of the
web-parts and rim in the position they occupy before the wheel is finished.
Figure 4 is a detail section drawn to an enlarged scale showing the relation of the
web-parts and rim to each other when the wheel is finished.
The same letters of reference denote the same parts.
A represents the wheel rim. It has a rib a extending around its inner face a¹ and
The interior
grooves a², a are formed in the opposite sides respectively of the rib a.
portion of the wheel consists mainly of the discs B B. These discs are composed of
elastic material such as steel and at the centre thereof they are provided with bosses
attached to or shaped to form the hub parts CC respectively. The preferable
practice is to make the disc and its hub-part integral. The hub-parts are as shown,
thicker than the surrounding portion of the discs and the hub-parts together form
a suitable hub for the wheel.
At the periphery thereof the discs are each provided not only with the inwardly
turned flange b but also with the outwardly turned flange b'. The two flanges b b¹
together with the thickness of the disc constitute a broad bearing for the disc at its
contact with the rim. The inwardly turned flange b engages in the opposing
grooves a³ in the rim rib. The outwardly turned flange 61 is of value in holding the
disc from springing away from the rib a. An additional feature of the construction
is as follows: The inner face of the rim at the points a³, a' at which the discs bear
thereon, instead of being parallel with the axle D are inclined thereto as shown.
That is, the end of the bearing toward the rib a is farther from the axle than is the
outer end of the bearing. This operates to more effectually secure the peripheral
portion of the disc in its position against the rim.
The parts of the wheel are united as follows, the hub parts are arranged apart
from each other upon the axle D and the discs at the periphery thereof are engaged
loosely with the rim substantially as shown in Figures 1, 3, saving that the axle is
not shown in these Figures, the hub parts are then forced and closed together upon

page_text: the axle and the parts thereby shifted into the position shown in Figures 2, 4, and
after they are thus adjusted it may be desirable to employ tie-bolts E, to more
effectually secure the hub parts together upon the axle. The hub parts are fitted
snugly to the axle, and hydraulic machinery or other suitable power is requisite to
close them together as described. As the hub-parts are thus closed toward each
other the discs whose inner portion necessarily follows the hub-parts are sprung
radially towards the rim and their peripheral portion is thereby fitted tightly to the
rim as shown in Figures 2, 4, and a very strong, as well as otherwise desirable,
wheel is thereby obtained.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents I declare that what I claim is :-
First The combination, in a wheel of the wheel-rim and the discs, said wheel-
rim having the grooved rib, and said discs each having the two flanges, substantially
as described.
Second In a composite wheel having a web consisting of discs of elastic material
and attached in position by causing them, at the periphery thereof, to bind against
the rim, and at the centre thereof, against the hub, or axle as described the
combination of the rim and the discs, each having the outwardly-turned flange b¹,
substantially as described.
Third-The combination in a composite wheel of the wheel rim having the grooved
rib and the inclined bearings with the springy discs cach having the flanges b, bl
substantially as described.
Fourth The combination of the axle the two hub parts, the springy discs each
having the peripheral flanges, and the rim having the grooved rib, substantially as
described.
Fifth A car-wheel having the bub-parts, the elastic discs and the rim said hub
parts and discs being integral and said discs being capable of moving radially
outward and interlocked with said rim substantially as described.
