1, CHARLES CROSBY I OUNG, CILIzen of the unten Di
of Ellsworth, County of Hancock, State of Maine, one of the United States of
America, Trader, 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 consists of an improved axle lubricator and is illustrated in the
accompanying drawings in which
Fig. 1. is a longitudinal, sectional view of hub with lubricator in position.
Fig. 2. is an elevation of screw plunger raised with oil cup in longitudinal
section.
Fig. 3. is an elevation of lubricator with screw plunger partly lowered.
Similar letters refer to corresponding parts throughout the figures.
I provide an oil cup or reservoir A of convenient capacity offset at the bottom
to a chamber B of diminished size, and terminating at its lower extremity in a
The
bevelled point b furnished with a minute vent c about the size of a pin head.
interior of the diminished chamber B is shaped to correspond with the exterior
bevel and to receive and fit the point d of the plunger D, while the exterior of the
chamber B and the lower portion of A are screw-threaded and the upper portion
of A is nut faced.
The plunger D is formed with a point d shaped to fit the diminished chamber B
and with screw threaded shank d' working through the cap or cover a of the cup A.
The plunger is of such length as to permit its point to rest in the bottom of the
chamber B when fully screwed down. The point then acts as a stopper and
prevents further flow of the oil. The point may if desired, be faced with rubber.
The whole plunger is operated by the fingers.
A gouge or slot E is formed upon one side of the shank of the plunger of a
length slightly greater than the thickness of the cover of the cup and of such
depth as to permit the entrance and passage of a stream of oil when the slot is
brought opposite the edge of the cover of the cup, as shown in Fig. 2.
located preferably slightly below the middle of the length of the shank.
It is
In operation, the hub being bored for the purpose, the lubricator is screwed into
position so that the vente may discharge upon the axle F. The screw plunger D
is raised to the position shown in Fig. 2. and the oil introduced through the slot E
to such quantity as may be desired. The plunger D is then screwed down until
the slot E is entirely within the reservoir and below its cover whereby the whole
top is now tightly closed. The plunger may now be screwed down to the bottom
of the lower chamber B the oil in that chamber being, of course, forced out through
the vent c upon the axle, and when more oil is required, the plunger is raised from
the chamber B which again fills instantly, when, the plunger being screwed down, the
oil is again forced out and the axle lubricated.

page_text: The filling and emptying of the reservoir being accomplished in the manner
above indicated, it is apparent that the wheel need never be removed for the
purpose of lubrication.
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 :
A lubricator consisting of the combination of an oil cup having a chamber
communicating with, and located above, a smaller chamber terminating at its lower
extremity in a discharge passage; aud a plunger having a screw-threaded shank
operating in the cover of said large chamber and a point shaped and fitted to be
introduced into and fill said small chamber and to be raised out therefrom, the
shank of said plunger being gouged or slotted longitudinally for a portion of its
length towards its lower end.
Dated this 22nd day of March 1894.
