PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means for Lubricating the
Bosses of Pulleys and Wheels of all descriptions.
"I JOSEPH HORTON of Copley near Halifax in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows:
The object of my invention is to facilitate the lubrication of pulley and wheels
of all kinds, and to retain the lubricant therein; also to keep it free from dirt, and
such lubricant will only occasionally requiro replenishing.
1 form a reservoir within the boss of the pulley or wheel preferably of a circular
or rounded shape, this reservoir is formed equally around the shaft; in the boss is
fixed a feeder or neck which projects into the reservoir almost to the shaft, to form
a trap in the pocket inkstand form, so that in whatever position the feed hole is,
the lubricant caunot escape. On rotation of the pulley or wheel, the lubricant is
drawn by gravitation to the centre, and so does not escape at sides as in the
ordinary construction, as the centrifugal action also causes air to be drawn from
the sides and discharges it out of the feed hole, this tends to bring the lubricant
back to the reservoir, rather than waste it as heretofore.
By preference I form the feeder or neck of piping screwed into the boss
and rivetted so that it is impossible for it to work loose, or for the oil to penetrate
through.

COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Lubricating the
Bosses of Pulleys and Wheels of all descriptions.
1, JOSEPH HORTON, of Copley near Halifax, 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:-
The object of my invention is to facilitate the lubrication of pulleys and wheels
of all kinds, and to retain the lubricant therein, also to keep it free from dirt, and
such lubricant will only occasionally require replenishing.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation in section of loose pulley with my improvements
applied.
Fig. 2 is an elevation in section of loose narrow pulley with my improvements
applied.
Fig. 3 shows end view of Fig. 2.
I form a reservoir A within the bosses
of the pulley or wheel, preferably of
a circular or rounded shape; this reservoir is formed equally around the shaft C.
In the boss B is fixed a feeder or neck D which projects into the reservoir to
form a trap, (in the adjustable pocket ink-stand form) so that in whatever position
the feed hole is, the lubricant cannot escape.
On rotation of the pulley or wheel, the lubricant is drawn by centrifugal action
to the extreme diameter of the boss, and so does not escape at sides as in the
ordinary construction.

page_text: As the centrifugal action also causes air to be drawn from the sides and
discharges it out of the feed hole, this tends to bring the lubricant back to the
reservoir rather than waste it as heretofore.
By preference I form the feeder or neck of piping screwed into the boss and
rivetted, or cast in, so.it is impossible for it to work loose, or for the oil to penetrate
through.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what-I
claim is :-
Lubricating loose pulleys and other wheels by forming circular reservoirs such
as A, within the bosses B, with oil tubes or feeders D, communicating from the
outer boss or rim to the inside of the reservoir, forming a trap, as and for the
purposes shown and described.
Dated in Twenth day of May 1892.
