1, LEONARD WILLIAM PARKER, of No. 165 East 68th Street, New York City
in the County and State of New York, United States of America, Engineer, do
hereby declare the nature of this invention to be as follows:-
The invention consists of an oil cup attached directly to the part to be lubricated
as the hub of a pulley, a crank pin or other moving device, and for filling it with a
lubricating substance (preferably heavy viscous oil, tallow or the like) with an air
pipe attached at its inner end to the outer end of the cup, and extended forward
relatively to the direction of rotation and also outward relatively to the axis of
rotation, whereby the outer end which is open to the atmosphere has a larger range
of movement through space than the range of the outer end of the cup, and
competent to cause pressure of air on the oil in the cup to overbalance the effect of
centrifugal action on the oil and force it into the bearing.

Improvements in Lubricators for Loose Pulleys, Crank Pins, and
other Moving Devices.
I, LEONARD WILLIAM PARKER, of No. 165 East 68th Street New York City,
in the County and State of New York, United States of America, 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:-
My invention relates to the kind of lubricators for loose pulleys and crank pins
having an air compressing attachment whereby through the motion of the pulley or
crank-pin, compressed air takes effect on the lubricant to overcome centrifugal
action and ensure more effective impingement of the lubricant on the shaft or
crank-pin to be lubricated, my invention being designed more particularly for the
use of tallow or other viscous lubricant of sluggish action.
My invention consists of an oil cup attached directly to the part to be lubricated,
as the hub of a pulley, a crank pin or other moving device, and adapted for filling
it with a lubricating substance, as preferably, heavy viscous oil, tallow or the like,
with an air pipe attached at its inner end to the outer end of the cup, and extended
forward relatively to the direction of rotation, and also outward relatively to the
axis of rotation, whereby the outer end which is open to the atmosphere has a

page_text: larger range of movement through space than the range of the 'outer end of the
cup, and competent to cause pressure of air on the oil in the cup to overbalance the
effect of centrifugal action on the oil and force it into the bearing.
Referring now to the accompanying drawing :-
Fig. 1, is a side view of a loose pulley and sectional view of the lubricating cup,
and my attachment for loose pulleys.
Fig. 2, is a side view of a crank and part of a connecting rod and section of the
lubricating cup, with my attachment adapted for crank-pins.
The lubricator a, is attached to the hub b, of the loose pulley c or to the cap d, of
the connecting rod e, in the usual way, said cup having the usual or any approved
filling orifice, and plug g, for closing it. To the outer extremity of the cup
I connect the small air inlet pipe in the case of the loose pulley, and the like but
shorter pipe i, in the case of the connecting rod, the pipe h being extended about
half the circuit of the axis of the loose pulley in the direction in which the pulley
is to be run, and divergent from the axis of the pulley so that the end terminates
near the rim of the pulley and traverses a greater range than the range of the cup.
The short pipe i, only extends far enough to point in the direction tending to force
air into the cup during part of the circuit of the crank-pin j, and to ensure air
compression above the oil, and on the forward end of each pipe I prefer to fit a
cap having a small perforation 1, and being of oval form adapted to cause
divergent action of the air to throw off dust particles and only admit a small beam
of air so to speak-which will be relieved of dust particles through the effect of
the oval ended cap.
It will be seen that when the pulley stops so that the pipe hangs with its outer
end lower than the lubricator cup, said cup will be so high that the lubricant will
remain in it by gravitation; and when the cup stops in a lower position the open
end of the pipe is so high as to prevent escape of the lubricant, and the lubricant
will in no case escape by siphonic action as it will in some cases when the pipe
extends an entire circuit of the axis or nearly so.
I am aware that a concentric tubular oil reservoir making an entire circuit of the
axis of the pulley or nearly so, and having an air inlet at the outer end having less
range in space for air compression than the oil, or part of it has for centrifugal
action, and also having a valve at the outer end to prevent escape of oil but which
is also obstructive to the action of the air, said reservoir also having a regulating
valve for the oil at the inner end, has been proposed and I make no claim for such
a device my invention being essentially an open air inlet tube. attached to the outer
extremity of the lubricator cup.
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 that what I
claim is,
In a lubricator for a moving device, as a loose pulley, or a crank-pin, the
combination with an oil cup attached directly to the part to be lubricated, and
provided with means for filling it with the lubricant, of an air-pipe attached at its
inner end to the outer end of the cup, and extended forward relatively to the
direction of rotation and also outward relatively to the axis of rotation, whereby
the outer end which is open to the atmosphere has a larger range of movement
through space than the range of the outer end of the cup, and competent to cause
pressure of air on the oil in the cup to overbalance the effect of centrifugal action
on the oil, and force it into the bearing substantially as described.
