PROVISIONAL SPECIFICATION.
Improvements in Self Lubricating Bearings for Guide Pullies and
the like.
I, THOMAS OWEN of 27 Albert Road, Saltaire, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to certain improvements in the construction of bearings,
particularly applicable to guide pulley axles, and has for its object the construction
of the axle or shaft bearing in a manner that lubricant is retained in the bearing
and the same continuously and automatically lubricated, and to so arrange the
bearings that when worn out on one side, they may be readily reversed.
In carrying out my invention I form a bush for each bearing with a reservoir at
one end for the storage of the lubricant, and at the other end of the bush I form a
flange at some distance from the said bush, thus forming a recess.
Into the before mentioned recess is placed a washer of flexible material such as
leather, which is shrunk tight on the axle or shaft, fills the recess and is held in
position between the end of the bush and before mentioned flange.
The reservoir may be entirely filled with lubricant or for some distance up from
the bottom towards the centre of the shaft or axle, so that the same revolves in the
lubricant, the before mentioned washer preventing the lubricant running away out
of the open end of the bush.
The bush is secured to the bracket by screws so arranged that by the reversal
of the bush, the opposite side may be utilized.

Improvements in Self Lubricating Bearings for Guide Pullies and
the like.
I, THOMAS OWEN, of 27, Albert Road, Saltaire, in the County of York,
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 relates to certain improvements in the construction of bearings
such as are applicable to guide pulley axles, and has for its object, the construction
of the pulley axle bearing in such a manner that, lubricant is retained in the
bearing so that it is continuously and automatically lubricated, also to so arrange
the bearings that, when worn out on one side they may be readily reversed.
In describing my invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents a front view of a guide pulley and frame, part of which is in
section, and
Fio 2 is an and view

page_text: In carrying out my invention, the upper portion of the frame A. and attachment
bracket B. are of the ordinary construction, the bottom of each leg terminating
with an enlargement or boss C. in which I forn a bearing by inserting a
bush D.
At one end of each bush D. is a reservoir E. for the storage of lubricant, which
may be supplied through the cup F. and at the other end of each bush is a space
between the said bush and a flange G.
Into the before mentioned space is placed a washer H. of flexible material such
as leather, which is nipped tight against the flange G. by means of the bush D.
The reservoir E. may be filled with lubricant for some distance up towards the
centre of the pulley axle J. so that the said axle revolves in the lubricant, the
washer H. retaining the lubricant by preventing it running away to any great
extent through the open end of the boss C. into the cup L. below.
Each bush D. is secured to the boss C. by screws M. M. the portion inserted in
the boss is circular, so that by removing the screws M. M. the bush D. may be
reversed, placing the worn portion at the top, thus enabling the opposite side to be
utilized.
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. The combination with pulley axle J. of a bush D. and washer H. inserted
within boss C, all arranged substantially in the manner and for the purpose as
herein before set forth and illustrated.
2. A boss C. arranged with a flange G. and a space intervening between the said
flange and the movable bush D. for the purpose as hereinbefore described and
illustrated.
