Improvements in Lubricators.
I, WILLIAM SMITHSON CHANTRELL of Breck Bank, Wallasey, in the County of
Chester, Oil Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has for its principal object, a lubricator that can be used with
solid or semi solid lubricants that will not run into the bearings of themselves by
gravity.
It consists in 1st. A cup of glass, brass, or other suitable material, or combination
of materials, having a narrow tube or orifice leading to the bearing, 2nd A piston
well fitting this cup or cylinder so as to slide therein, 3rd A screw stem passing
through the cover of the cup and the piston, and either the hole in the boss of
the cover is tapped or threaded to fit the screw stem, and the piston riveted or
otherwise secured to the end of the stem, or the stem bears with a collar on the
inside of the cover, with no thread on either cover or part of stem passing through
the cover, and the piston hole is tapped or threaded to fit the stem. 4th The cover
already referred to which is firmly screwed onto the cap preferably by overlapping
Hange. 5th In a hand-wheel, button or handle which, if the stem is screwed
through the piston, is firmly keyed, pinned, or otherwise fixed to the stem in such
manner that it can be taken off when required. This is to enable the cup to be used
as an ordinary lubricator for oil if required by simply withdrawing the piston and
stem and inserting a cork or its equivalent into the hole in the cover if required.
6th When the piston is loose on the stem 1 continue sometimes to put an indicator
on the piston, and place a hole above in the lid for it to project above when nearly
empty, but prefer a window of glass instead. If glass be used I use a cement of lime

on by oil, and if a glass cylinder be used I prefer to fasten the brass rim and bottom
to it, by dovetail joint and cement or other joint, that will have something more
than the mere holding power of the cement to hold it.
Or the joint can be screwed and be formed with white or red lead, sometimes I
make the cylinder of brass or other metal with a glass lining and pierce the brass
with holes or wide spaces for windows.

page_text: I, WILLIAM SMITHSON CHANTRELL of Breck Bank, Wallasey, in the County of
Chester, Oil Merchant, 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 principal object, a lubricator that can be used with solid
or semi solid lubricants that will not run into the bearings of themselves by gravity.
It can also if necessary be used for oil.
The drawing shows a sectional elevation of a lubricator in accordance with my
invention.
In this A is a cup of glass, brass, or other suitable material, or combination of
materials, having a narrow tube or orifice B leading to the bearing into which it is
screwed. is a piston well, fitting this cup or cylinder so as to slide therein, and is
well packed with leather, and screwed up by nut D against the abutment E on the
piston rod F, which is turned down and screw threaded for this purpose. F is a
screw stem passing through the cover G of the cup A, the hole H in the boss of the
cover G is tapped or threaded to fit the screw stem. In place of this arrangement,
the hole in the cover and the stem, where it passes through said hole, can be
smooth and unbored, the stem being provided with a suitable collar abutting
against the cover. The piston in this case has a central boss, is tapped with a screw
thread, and is screwed to-and-fro on the stem by rotating the latter. 1 do not,
however, recommend this modification, so do not show a drawing of it. The cover G
is firmly screwed onto the cap preferably by overlapping flange J. K is a hand-
wheel, button or handle which, is firmly keyed, pinned, or otherwise fixed to the stem
preferably in such manner that it can be taken off when required. This is to enable
the cup to be used as an ordinary lubricator, for oil if required, by simply withdrawing
the piston and stem, and inserting a cork or its equivalent into the hole in the cover,
if required. When the piston is loose on the stem, I sometimes put an indicator on
the piston, and place a hole above in the lid for it to project above when nearly
empty, but prefer a window of glass instead. If glass be used, I use a cement of
lime, and white of eggs, plaster of Paris, and alum or other hard, tough cement
not acted on by oil, to fit it into the body, and if a glass cylinder be used, I
prefer to fasten the brass rim and bottom to it, by dovetail joint and cement or
other joint, that will have something more than the mere holding power of the
cement to hold it. Or the joint can be screwed, and be formed with white or red
lead, sometimes I make the cylinder of brass or other metal with a glass lining,
and pierce the brass with holes or wide spaces for windows.
In the example, shown in the drawing, however, which is preferably entirely of
brass, the height of the wheel above the bottom indicates the approximate amount
of lubricant in the box with sufficient exactitude.

page_text: The mode of action is as follows:
The piston being screwed up to the cover, the latter is removed by unscrewing
rim or flange J, the box is then filled with lubricating grease, and the lid again
screwed in place. To lubricate the bearing, occasionally screw down the hand
wheel K half a turn or so at a time. This forces the lubricant through duct B.
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 :-
.
The arrangement of lubricator, substantially as described, and as illustrated in
the accompanying drawing, by which means it can be adopted for hand feeding
with grease or nearly solid lubricant, or the piston and piston rod temporarily
removed, and then used for liquid lubricants, and be again speedily readjusted for
solid lubricant.
