Improvements in Lubricators.
I, DANIEL DUNCAN BROWN 10 Park Drive, South, Whiteinch, Glasgow,
Oil, Grease and Chemical Manufacturer do hereby declare the nature of this
invention to be as follows:
-
The improvement which I have made in lubricators, in which semi-solid lubricants
can be used, consists in my construction of lubricators whereby the supply of the
lubricant can be regulated to feed faster or slower as may be required for the various
kinds of engines & machinery that are used.
For this purpose, I make a cylinder; and, to one end, I attach a cup the inside
diameter of which gradually decreases from the part that is attached to the cylinder
which is its largest diameter, to the opening which lets out the lubricant which is
its smallest diameter. I now screw the other end of cylinder to any required
distance from end of cylinder; and fit it with a correspondingly screwed cover.
I then make a piston to fit the inside of cylinder; and attach to this piston a

piston-rod the other end of which passes out through a hole in the cover.
a tapering spiral spring on the piston-rod inside the cylinder between the piston
and the cover. I bore a small hole in the piston-rod near the piston; and drive
into the hole a pin which is made to project a little beyond the sides of the
piston-rod.
I then make two small slots opposite each other in the cover at the opening
which the piston-rod passes through, to let the piston-rod with projecting pin be
pulled out through the cover. I also attach a small knob or handle to the end of
piston-rod which projects through the cover.
To use this lubricator, I pull out the piston-rod past the pin in piston-rod; and
give it a quarter of a turn which fixes the piston-rod in that position. I now unscrew
the cover of the lubricator, fill the lubricator with the lubricant, and screw the
cover on again.
I then give the piston-rod a quarter of a turn which enables the pin in the
piston-rod to pass freely through the slots in cover of lubricator, thereby releasing
the spring which, by pressing on the piston, pushes out the lubricant, the gradually
tapering cup which I have before described greatly assisting in the easy exit of
the lubricant.
I screw
To regulate the lubricator so as to force out the lubricant more quickly,
the cover of the lubricator further on to the cylinder, thereby increasing the pressure
of the spring on the piston which pushes out the lubricant; and, to make it push
out the lubricant more slowly, I screw the cover of lubricator a shorter distance on
to the cylinder, thereby lessening the pressure of the spring on the piston which, in
Consequence, pushes out the lubricant more slowly.

I, DANIEL DUNCAN BROWN, residing at 10 Park Drive South, Whiteinch,
Glasgow, in the County of Lanark, Oil and Grease Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly des ribed and ascertained in and by the following
statement :-
The improvements which I have made in lubricators in which semi-solid lubricants
can be used, consist in my construction of lubricators whereby the supply of the
lubricant can be easily regulated to feed faster or slower as may be required for
the various kinds of engines and machinery that are used.
For this purpose, I make a cylinder A to which I attach a cup B. The diameter
of the cup B gradually decreases towards the bottom of the cup at 61 in the usual
way but I also gradually decrease the diameter of the opening in the shank of
the cup from the bottom of the cup at 1 towards 2 which is at the outlet of the
shank. I now screw the other end of cylinder to any required distance from
the end of cylinder; and fit it with a correspondingly screwed cover C. I then
make a piston D to fit the inside of cylinder. I now make a piston-rod E to pass
through a hole in center of cover C. On the end of piston-rod inside of cylinder,
I fix the piston D. I put a tapering spiral spring F on the piston-rod inside the
cylinder between the piston D and the cover C. I bore a small hole in the piston-
rod near the piston and drive into the hole a pin G which is made to project a little
beyond the sides of the piston rod. I then make two small slots opposite each
other in the cover at the opening where the piston-rod passes through, to let
the piston-rod with projecting pin be pulled out through the cover. I also attach
a small knob or handle to the end of piston-rod which projects through the
cover.
To use this lubricator, I pull out the piston-rod E past the pin G; and give it
a quarter of a turn which fixes the piston-rod in that position. I now unscrew the
cover, fill the lubricator with the lubricant, and screw the cover on again. I then
give the piston-rud a quarter of a turn which enables the pin in the piston-rod to
pass freely through the slots in the cover, thereby releasing the spring which by
pressing on the piston pushes out the lubricant, the tapering form of the cup and
the shank assisting in its easy exit.
To regulate this lubricator to feed the lubricant more quickly, I screw the cover
further on to the cylinder, thereby increasing the pressure of the spring on the
piston which pushes out the lubricant; and, to make it push out the lubricant more
slowly, I screw the cover a shorter distance on to the cylinder, thereby lessening
the pressure of the spring on the piston which in consequence pushes out the lubricant
more slowly.
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 -
1. In a lubricator for use with semi-solid lubricants, a taper opening in the shank
of lubricator substantially as described.
2. In a lubricator for use with semi-solid lubricants, a combination of the
parts forming the lubricator arranged and acting as hereinbefore set forth and
described.
