An Improved Journal Bearing.
I, PERCY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Manager, do hereby declare the nature of this invention (a communication
to me from abroad by Bruno Beaupré, of St. Paul, Minnesota, U.S.A., Gentleman,)
to be as follows:-
:-
The object of this invention is to provide a journal bearing more especially
applicable to cycles and light vehicles; but also applicable for use in connection.
with light and delicate machinery.
The improved bearing comprises an annular casing preferably made in halves and
united by bolts passing through lugs formed integral therewith. Packing-pieces
consisting of thin pieces of tin, leather or the like may be placed between the
lugs and are intended to be gradually removed as the parts of the bearing become.
worn.
The casing takes the form of a broad ring of convenient diameter and having-
two annular grooves on its inner surface and arranged a short distance from each-
side of the casing.
A series of small steel balls are arranged within the grooves aforesaid and are
retained in position in each groove by a ring; the outer periphery of which is.
grooved to bear upon and receive said balls.
The axle passes centrally through the casing; and between the axle and casing-
a series of rollers, of the same length as the width of the casing, are arranged..
These rollers have a groove near each end to coincide with and receive the inner
periphery of each of the rings aforesaid.
The last mentioned rollers are kept equi-distant by a series of rollers of smaller
diameter arranged between them and in contact with the inner surface of the
afore-referred-to rings.
The casing is fitted with sides consisting of metal discs having a central aperture
for the axle to pass through freely.
In order to keep the bearing in place upon the axle, one or more grooves are
made on the outer surface of the discs aforementioned, and in said groove or grooves
a series of balls are arranged. These balls are kept in place by a disc secured to
the shaft on each side of the bearing, and having a groove or grooves formed upon
their inner faces to receive the said balls.

COMPLETE SPECIFICATION.
An Improved Journal Bearing.
1, PERCY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Consulting Engineer, do hereby declare the nature of this invention
(a communication to me from Bruno Beaupré of St. Paul, Minnesota, U.S.A.,
Gentleman), and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention is to provide an improvement in bearings of that

page_text: class commonly used in the construction of cycles; but which can also be adapted
to other machinery where a minimum of friction is desirable.
Reference being had to the drawings,
Fig. 1, is a front elevation of a complete bearing:
Fig. 2, an end elevation :
Fig. 3, a front elevation with the cover and shaft removed :
Fig. 4, a diametrical section of Fig. 1.
The casing A is formed with internal annular grooves B, and is fitted with
covers C, D.
The shaft E passes centrally through the cover C and abutts against the
steel balls F arranged in the annular groove G in the block H screwed into the
cover D and secured from movement by the lock-nut I. Rings J are loosely fitted
in the grooves B and run upon steel balls K, also arranged in said grooves.
Friction rollers L are arranged around and between the shaft E and the inner
surface of the casing, and are retained equi-distant by rollers M. The rings J
prevent end movement of the rollers L.
The casing A is adapted to be attached to a cycle or other machinery in the
usual and well known manner. When the shaft E rotates, its movement is imparted
to the rollers L running on the inner surface of the casing A. The rollers L
rotate the rollers M which in turn revolve the rings J running on the balls K.
The end-thrust of the shaft E is taken by the balls F.
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
A journal bearing comprising the casing A having annular grooves B, rings J
fitted in said grooves and running upon balls K, the rollers L and M arranged as
shewn, the cover D fitted with the block H, balls fitted in an annular groove in
block H, and the cover C having a central aperture to admit a shaft, all
substantially as and for the purposes hereinbefore set forth and illustrated in the
drawings hereunto annexed.
Dated this Sixth day of November 1894.
