I, DANIEL HARTLEY, of 54, Heath Street, Leeds Road, Bradford, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
j
This invention relates to a new or improved lubricator for loose pulleys, and its
object is to effect economy in the use of lubricants and preserve the shafts on which
such pulleys are mounted.
For this purpose I employ a sleeve approximately the width of the pulley in
connection with which it is to be fitted. The pulley is mounted on the said sleeve and
it is provided at one end with a hollow collar, forming a chamber for the lubricant,
having an orifice for filling said chamber and fitted with a set screw adapted to fix
said collar and sleeve upon the shaft. An oil channel is cut along the periphery of
said sleeve and communicates with the interior of the said chamber. Such oil channel
is filled with felt or other suitable material capable of drawing the oil from said
chamber and distributing it to the loose pulley as required.

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 a new or improved lubricator for loose pulleys, and its

the pulleys are mounted.
For this purpose I employ a sleeve approximately the width of the pulley in
connection with which it is to be fitted. The pulley is mounted on the said sleeve
which is provided at one end with a hollow collar, forming a chamber for the lubricant
and having an orifice for filling said chamber and fitted with a set screw adapted to
fix said collar and sleeve upon the shaft. An oil chamber is cut along the periphery
of said sleeve and communicates with the interior of the said channel. Such oil
channel is filled with felt or other suitable material capable of drawing the oil from
said chamber and distributing it to the loose pulley as required.
Reference is to be had to the accompanying drawing forming a part of this
specification in which similar letters of reference indicate corresponding parts in each
of the figures.

Figure 1, represents a longitudinal section of my improved self lubricating sleeve
fixed upon a portion of a shaft and having a section of a pulley mounted thereon.
Figure 2, is a transverse section through the said sleeve.
Figure 3, is a transverse section through the said collar forming the oil reservoir.
Figure 4, is a plan of the lubricator.
The parallel sleeve A is bored to fit the shaft B and its outside diameter is turned
to the size of the central hole through the pulley C, which is mounted thereon. A
hollow collar D at one end of said sleeve forms a chamber E for the reception of the
lubricant and is provided with a screw plug H closing the mouth J and fitted with a
set screw K passing through the solid portion I. of the collar and adapted to fix said
collar and sleeve upon said shaft. An oil channel M communicating by the duct N
with the chamber E is formed along the periphery of the sleeve A and is filled with
felt, wick, or other suitable material capable of drawing the oil from the said chamber
and distributing it to the loose pulley as required.
It is obvious that the lubricator may be keyed or otherwise fixed to the shaft instead
of employing the set screw K.
I find casting to be the most convenient method of forming my improved lubricators,
the chamber E and preferably the duct N being moulded by means of a suitable core
or cores.

page_text: 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 what I claim is:
x
1. A lubricator for loose pulleys consisting of, a sleeve forming a bearing for the
pulley provided with an oil chamber and a channel communicating with the said oil
chamber adapted to distribute oil to the said bearing, substantially as herein shown
and described.
2. The combination with the sleeve A, of the chamber E the channel M, and the
set screw K, substantially as herein shown and described and for the purpose
specified.
