COMPLETE SPEĊIFICATION.
I PATRICK BROWNLEY a subject of the Queen of Great Britain and Ireland,
residing at St. John, New Brunswick, in the Dominion of Canada, Brassworker,
do hereby declare the nature of my Invention for "IMPROVEMENTS IN ROLLER
BEARINGS," 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 anti-friction boxes, bushes, or bearings for machinery
and ship's blocks, pulleys and other purposes the nature of which is hereinafter
fully explained.
Referring to the Drawings:-
Figure 1 is a front view, and
Figure 2 a back view of the device complete.
Figure 3 is a vertical section taken on the line x, x, Figures 1 and 2.
Figure 4 is an internal face view and
Figure 5 a section of the plate B.
Figure 6 is an internal view and
Figure 7 a section of the plate C.
Figure 8 is a front view, and
Figure 9 a section of the casing A.
:
In each of the views similar letters of reference are employed to indicate
corresponding parts wherever they occur.
A, represents the main shell frame, or case of the box, bush, or bearing, which
is provided with a lateral flange or projection A¹, by preference formed circular,
as shown in the Drawings; and provided with screw holes a, for the passage of
rivets, screws or bolts for the retention of the device in position. The flange or
projection A, may howevor be formed in sections or provided with lugs if desired.
The front of the flange or projection A', is counter-sunk or recessed at A³, for.
the purpose of receiving a rotating plate B, which snugly fits said recess and
which is provided with two or more extension rivets, rods or connections b, passing
through the chamber A³, formed within the frame or case A.
The rivets, tie rods or connections b, are received into openings c, forined in a.
plate C, adapted to revolve with the plate B, the bearing of which is against the
rear face A, of the frame A, which is turned true so as to avoid friction or twisting.
of the nest of rollers.

page_text: The plates B, and C, revolve together by reason of their connection, by means
of the rivets or tie rods b. The rivets or tie rods b, are screw-threaded at b', and
either provided with screw nuts 6, or rivetted, or equivalent devices for holding
the plates B, and C, correctly in position. The plato B, revolves in a recess-bearing
formed in the flange, and plate C, on a bearing formed on the rear end of the box,
and against said box, and which plate forms the rear end of the box A.
The plates B, and C, are each formed with a series of recesses D, which are
constructed with oil jackets or may be tapering at their extreme ends, and are
provided with small apertures d, for the purpose of facilitating lubrication, and
also for the discharge of dirt or waste oil, or matter from the device, and in order
to save trimming off ends of rollers, and for a guide for milling tool.
Upon each of the plates B, and C, are projections E, by preference formed by
turning out a portion of the casting of the said plates.
The projections on each of the plates B, and C, are adapted to form seats or
bearings e, for the ends of a series of anti-friction rollers F, which are arranged
around in a circle-so as to leave a central circular aperturo G, for the passage of the
shaft H, and so arranged that no two of the rollers come into contact.
The operation of the device is as follows:-
The shaft H, is supported primarily by the rollers F, which turn on the shaft E,
and are so kept in position by the projections on the plates, that they do not touch
each other, and the plates revolve with the rollers, thereby avoiding friction. The
rollors F, being supported in seats e, in the plates B, and C, which are connected
together by the rivets or tie rods b, the said plates B, and C, will revolve but once
to several revolutions of the roller, and the combined action of-the anti-friction
rollers F, and the plates B, and C, will prevent or greatly lessen the friction on
the shaft H, and the shell A. The platos, rivets and rollers may also be used in
sheaves made of cast iron or other material in the same manner as described when
used in the shell, frame, or case. Where so used the inside of the sheaf or strap
opposite oach plato B, C, must be counterbored in order to give the plates clearance,
or space in which to revolve without coming in contact with the sheaf or straps.
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. An anti-friction bush, box or bearing provided with a series of revolving
rollers supported between plates or discs, said discs being adapted to revolve in
independent bearings, substantially as shown and described.
2. An anti-friction box or bearing provided with a series of revolving rollers
supported between plates provided with bearing-recesses so arranged that the
rollers shall not touch each other, and connected loosely by rivets, rods, or bars in
such manner that the said plates also revolve in independent bearings, substantially
as shown and described.
3. In an anti-friction box or bushing, the combination with the casing A,
revolving plates B, C, the former adapted to work in a bearing recess in the
casing, and the latter against the end thereof, and a series of rollers F, arranged
in position to support a shaft, or ship's blocks, carriage wheels, or other suitable
purpose, substantially as described.
4. In an anti-friction bush, box or bearing, the combination with a fixed case or
frame, of a pair of connected revolving discs or plates adapted to work in
independent bearings, and a series of anti-friction rollers working in recesses in
said plates, substantially as described.
5. In an anti-friction bush, box, or bearing adapted to keep the rollors in
position and equally apart by means of the recesses and projections on the end of
plates B, and C, being adapted to work in suitable bearings, substantially as
described.
6. A casing provided with a recess in one of its ends, and its other end having
a non-recessed bearing, in combination with revolving discs secured to each other

page_text: and having anti-friction rollers interposed between said discs, substantially as
described.
7. The combination with discs having raised projections from their faces in
which is formed recesses for journal-bearings, for anti-friction rollers, the said discs
being arranged face to face and suitably secured to each other by tie-rods,
substantially as set forth.
8. The combination in a device for lessening friction in journal-bearings, of the
plates or discs provided with oil jackets beyond the bearings of the anti-friction
rollers which are between said discs, substantially as shown and described.
9. The combination in an anti-friction journal-bearing box, of the bearing discs
and rollers, the said discs having projecting bearings and recesses therein, the walls
of said recesses being cut away so as to pernit the ready removal of the rollers
when the nest is detached from the box, substantially as set forth.
