PROVISIONAL SPECIFICATION.
Improvements in Bearings for Wheels, Pulleys, and the like.
I ALFRED DOPP of Hamersleben in the Kingdom of Prussia, Engineer, do
hereby declare the nature of this invention to be as follows:-
*-
This invention for improvements in bearings for wheels pulleys and the like has
for its principal object to construct the bearing in such manner that a continuous
lubrication is effected without any overflow or escape of the lubricant; and consists
essentially in forming a conical male or female bearing on the frame to which the
wheel pulley or the like is to be attached and corresponding conical female or
male bearing on the hub of the wheel pulley or the like which is secured in place
by a bolt passing through the axis of the bearing. The lubricant is supplied to a
chamber situated in a fixed part of the bearing.
In an arrangement suitable more especially for trucks, two wheels are mounted
as above described on the conical ends of a hollow axle and secured by a single
axial bolt. In mounting a pulley, it may be formed with conical bearings on either
side of its hub working in conjunction with corresponding conical bearings fixed to
the frame or support and secured in place by an axial bolt.

COMPLETE SPECIFICATION.
Improvements in Bearings for Wheels, Pulleys, and the like.
I ALFRED DOPP of Hamersleben, in the Kingdom of Prussia, Engineer 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 for improvements in bearings for wheels pulleys and the like has
for its principal object to construct the bearing in such manner that a continuous
lubrication is effected without any overflow or escape of the lubricant; and
consists essentially in forming a conical male or female bearing on the frame to
which the wheel pulley or the like is to be attached and corresponding conical
female or male bearing on the hub of the wheel pulley or the like which is secured
in place by a bolt passing through the axis of the bearing. The lubricant is supplied
to a chamber situated in a fixed part of the bearing.
In an arrangement suitable more especially for trucks, two wheels are mounted
as above described on the conical ends of a hollow axle and secured by a single
axial bolt. In mounting a rope or other pulley, it is formed with conical bearings
on either side of its hub working in conjunction with corresponding movable
conical bearings fixed to the frame or support and drawn together by an axial bolt.
In the accompanying two sheets of illustrative drawings
Fig. 1 is a sectional elevation of an axle and wheels with bearings constructed
according to this invention, and
Fig. 2 is a similar view of a modified construction.
Fig. 3 is a part elevation of a carriage suitable for a rope or elevated railway
provided with bearings constructed according to this invention, and
Fig. 4 is a horizontal section and

page_text: Referring to Figs. 1 to 2, the wheels a have either male or female conical
bearings formed on or in their bosses c and working in conjunction with female
or male bearings d formed in or on a hollow tube serving as a fixed axle for the
wheels to rotate upon. The two wheels on the axle of the truck are drawn
together and secured on the axle by means of an axial bolt passing through the
hollow tube e which also serves as a reservoir for a suitable lubricant.
In the arrangement shown in Figs. 3 to 5, the pulleys a are each formed on each
side with a conical boss which bosses work in conjunction with a fixed conical
bearing and a loose conical bearing i drawn towards the bearing h to fix the
pulley by means of the axial bolt f.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The arrangement of a conical bearing on a wheel working in or on a
corresponding conical bearing on a frame and secured together by an axial bolt
substantially as described.
2. A fixed axle for wheels of vehicles consisting of a tube having conical
bearing surfaces at its ends substantially as described.
3. Wheels provided with conical bearing surfaces and secured on to the
corresponding ends of a fixed tubular axle by an axial bolt substantially as
described.
4. A bearing frame for rope or other pulleys consisting of two conical bearing
surfaces working on corresponding conical bearing surfaces on either side of the
hub of the pulley and drawn together by means of an axial bolt substantially as
described.
5. Bearings for wheels pulleys and the like constructed substantially as described.
