I, THOMAS HILL of Finlay Drive Dennistoun, Glasgow, in the County of Lanark,
Scotland, Engineer, do hereby declare the nature of this invention to be as follows:-
This Invention relates to that class of Lubricators the outlet from which is controlled
by a loose or reciprocating feeding pin, piston, or valve; and has for its object to
ensure a positive actuation or reciprocation of said pin or valve, and thereby positive
feed.
The Lubricator as constructed for lubricating loose pulleys, for which it may be
specially applicable; comprises an outer cup or case for holding the lubricant, & pro-
vided with a charging lid or cap. The feed outlet branch is fixed into the nave of the
pulley, and is provided with a rod having a piston or valve attached thereto, which in
its normal position is kept shut by means of a spring or other equivalent. The said
rod projects radially outwards through a hole bored in the rim of the pulley, so as to
be pushed inwards by the belt every revolution.
As applied for lubricating the crank-pin of Motors or shafts, the lubricator is fixed
to the part encircling said crank-pin and moves therewith; the rod of the lubricator
being so made as to be actuated by the crank-pin every revolution.
The lubricator thus operates only when the Machinery to which it is applied is in
motion; the regulating pin, piston, or valve remaining shut, unless when actuated as
hereinbefore set forth.

Improvements in Lubricators.
I, THOMAS HILL of 43 Finlay Drive, Dennistoun, Glasgow, in the County of
Lanark, North Britain, 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 has for its object to ensure a positive actuation of the feeding valve
or pin of lubricators for loose pulleys or other analogous parts of machinery driven or
driving by belts. The annexed Drawings illustrate a convenient mode of and con-
struction of lubricator for application according to my invention. The cup a for
holding the lubricant is shown as fitted in two different positions with respect to and
into the hole m of hub or nave 6 of the pulley; the shaft on which the pulley revolves
being shown by dotted circle. The feeding spindle y of the lubricator is drawn out
by the spring c acting on the fixed washer d. The top of the spindle y is provided
as shown with an adjustable end e which projects through a hole bored in the rim n of
the pulley. The spindle g is pushed in by the belt i Fig. 1 when it overlaps it the
spindle being constructed as shown so as only to pass a certain quantity of lubricant
each time it is wrought, and shut off further supply in event of pulley stopping when
the belt keeps in the spindle; the lubricator thus operating only when the pulley to
which it is applied is revolving.
Having now particularly described and ascertained the nature of my said invention,
& in what manner the same is to be performed, I declare that what I claim is.
Effecting the lubrication of a loose pulley by means of the belt, substantially as set
