I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for IMPROVEMENTS
IN LUBRICATORS a communication to me from abroad by John J. Irvine of
Chattanooga in the County of Hamilton and State of Tennessee, United States
of America to be as follows:-
"
This Invention relates to an oil cup which is so constructed that the flow of oil
increases and decreases with the speed of the machine, no oil is wasted and the cup
cannot become clogged.
The oil cup is screwed on a plate which at its bottom is furnished with a neck
screwing into a cross head or other guide, and through a plate from which rises a
tubular standard. Through this standard a spindle passes loosely said spindle being
provided at its lower end with a bevelled projection which extends below the plate
supporting the standard and being surrounded by a spiral spring pressing it down-
ward, and guided by a transverse pin the ends of which project into vertical slots
in the sides of the standard. The spindle is screw threaded and on the part pro-
jecting from the top of the tubular standard a nut is screwed, upon which an arın is
held by an ornamental nut screwed on the upper end of the spindle. This arm is
provided on its upper surface with a recess or socket for receiving the nut and is cut
away to permit the spindle to pass on to the end of the arm.
The cover of the oil cup has an upwardly projecting neck and a concentric
internally screw threaded neck between which necks a filling funnel is screwed.
A spindle secured to the arm projects down to the bottom of the oil cup, and is
provided at its lower end with a pin of less diameter which fits in an aperture
extending through the neck at bottom of the cup. A washer is held on a shoulder
formed at the lower end of the spindle the upper end of the pin being provided
with a groove for receiving the inner edge of the washer and thus holding the
washer in place. If a reciprocating piece of machinery such as a cross head guide is
to be oiled, a bevelled block is fixed on the cross head to act on the bevelled pro-
jection of the spindle, and if a revolving shaft is to be oiled a cam projection is

said bevelled projection and force the spindles upward at each revolution of the
shaft thereby permitting a small quantity of the lubricant to pass through the hole
in the bottom of the cup. The plate which supports the standard is prevented from
turning by means of a pin on the guide or bearing entering said plate.
The movement of the spindles may be regulated by means of the nuts so as to
control the quantity of lubricant delivered every time the spindle is lifted, and a
scale is provided to show the stroke of the spindles.
If the spindle is to be removed for cleaning the cup the nut is loosened and then
the arm can be swung from the spindle. In filling the cup the funnel is partly
unscrewed and the oil is poured on to it, and passes down between the inner surface
of the funnel, and the oiler surface of the neck to the bottom of the space between
the necks, whence it flows through apertures in the cover into the cup.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LUBRICATORS" (a communication to me from abroad by John J. Irvine of Chatta-
nooga in the County of Hamilton and State of Tennessee, United States of
America,) 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 this invention is to provide a new and improved oil cup which is
so constructed that the flow of oil increases and decreases with the speed of the
machine, no oil is wasted and the cup cannot become clogged.
Reference is to be had to the accompanying drawings forming part of this
specification, in which, Figure 1 is a longitudinal sectional elevation of the
improved oil cup.
Figure 2 is an end view of the same.
Figure 3 is a plan view of the bottom plate of the oil cup.
Figure 4 is a side view of a bevelled plate for operating the oiler.
Figure 5 is a plan view of the arm for lifting the feeder.
A is the oil cup screwed on a plate A¹ provided at its bottom with a screw neck B
screwed into a cross head or other guide C, and through a plate D held between the
guide C and the plate A', which plate D is provided with a tubular standard E
through which a spindle F passes loosely which is provided at its lower end with a
bevelled projection F', which extends below the plate D, which spindle is surrounded
by a spiral spring G, pressing it downwards. The spindle F, is guided by a
transverse pin H, the ends of which project into vertical slots J in the sides of the
tubular standard E.
The spindle F is screw threaded and on the part projecting from the top of the
tubular standard E, a nut L³ is screwed upon which an arm L is held by an orna-
mental nut M¹ screwed on the upper end of the spindle.
The arm L is provided on its upper surface with a recess or socket for receiving
the nut M¹ and with a slit L¹ (see figure 5) to permit the spindle F to pass on to the
end of the arm.
The cover M screwed on the cup A is provided with an upwardly projecting
neck N and with a concentric internally screw threaded neck O, between which
necks the filling funnel P is screwed. A series of apertures a are formed on the
cover between the necks N and O. A spindle Q secured to the arm L projects
down through the neck N to the bottom of the cup, and is provided at its lower
end with a pin R of less diameter which pin fits in an aperture S extending through
the neck B. A washer T is held on the shoulder b formed at the lower end of the
spindle Q, the upper end of the pin R being provided with a groove d, for receiving
the inner edge of the washer and thus holding the washer in place. If a recipro-
cating piece of machinery such as a cross head guide O is to be oiled, a bevelled
block U is fixed on the cross head to act on the bevelled projection F of the

page_text: spindle F. If a revolving shaft V is to be oiled, a cam projection W is arranged
on the shaft V or on a ring on the shaft in such a manner that it can act on the
bevelled projection F at the lower end of the stem or spindle F and force the said
stem or spindle upward at each revolution of the shaft.
In operation, every time a cam or like device on a movable part of the machinery
strikes the lower end F of the spindle F the spindle is raised and raises the
spindle, thus permitting a small quantity of the lubricant in the cup A to pass
through the hole S to the movable part. By means of the nuts L' and M the
movement of the spindles F and Q can be regulated to be greater or less, according
to the quantity of lubricant to be delivered, every time the spindle Q is lifted. A
scale is formed at the side of one of the edges of one of the slots J so as to show the
stroke of the spindle F and of the spindle Q.
The spring G presses the washer T on the bottom of the cup and prevents a
leakage of oil.
If the spindle Q is to be removed for cleaning the cup, the nut M¹ is loosened
and then the arm L can be swung from the spindle F.
In filling the cup A, the funnel P is partly unscrewed and the oil is poured on to
it, and down between the inner surface of the funnel and the oiler surface of the
neck N to the bottom of the space between the necks N and O, whence it flows
through the apertures a into the cup.
If a revolving shaft is to be oiled the cam projection W on the ring V raises the
spindle F, once for each revolution and the shaft is oiled in the same manner as the
guide.
A pin e on guide or bearing Centers a hole f in the plate D to prevent turning of
the plate by the action of the cam W or block V on the end F¹ of the shaft F.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is

said socket for holding the arm L in place on the spindle F, substantially as herein
shown and described.
6th The combination with an oil cup, of the vertically movable spindle having
a pin R of less diameter than the said spindle to form a shoulder b on its lower end
