PROVISIONAL SPECIFICATION.
An Improved Means for the Lubrication of Piston-rod Guides and
other Surfaces.
I, JAMES Moss of Mossford Street, Bow in the County of Middlesex, Engineer do
hereby declare the nature of this invention to be as follows:-
This invention consists in lubricating the surfaces of piston rod guides or other.
surfaces by means of a pump of peculiar construction placed in communication on one
side with one of two oil reservoirs and on the other side with one or more perforated
pipes through which the lubricating oil is delivered to the surface to be lubricated.
In the case of using the invention for the lubrication of vertical piston rod guides
the pump is worked from one of the moving parts of the engine, namely the piston
rod, cross head or one of the guide blocks, the pump rod at the guide end working on
the perforated oil tube, and the pump itself at the bottom end working on a bearing
or journal formed on it so as to accommodate itself to the motion of the piston rod
and guide blocks. The suction valve is fitted in the bearing on which the end of the
pump oscillates. After passing the suction valve the oil passes through the piston and
pump rod-made hollow for the purpose-to the perforated tube. In the pump
piston is fitted a discharge valve. After serving the purpose of lubrication the used
oil falls into a catch oil box placed at the bottom of each of the piston rod guides. It
then falls by gravity through pipes into a reservoir placed on the condenser or any
other convenient place where it may be kept warm, this reservoir being fitted with
strainers for the separation of impurities. After purification it passes to a second
reservoir underneath which is in connection with the oil pump. In this way the same
oil may be used repeatedly.

COMPLETE SPECIFICATION.
An Improved Means for the Lubrication of Piston-rod Guides and
other Surfaces.
I, JAMES Moss of 21 Studley Road, Forest Gate, Essex, 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:
This invention is an arrangement consisting of a pump A the back end of which
works on a watertight trunnion bearing B and the hollow pump rod () is coupled so as
to work watertight on a perforated tube D, which is shewn fixed on piston rod
shoe.
From the trunnion bearing a suction pipe E is led to a collecting reservoir F, from
which the lubricant is drawn.
The receiving reservoir G, which is immediately above is suitably provided with
strainers, and receives the lubricant as it flows from the collecting boxes H, at foot of
piston rod guides or other surfaces, these boxes being also provided with strainers,
and otherwise protected from foreign matter.
The process of lubrication is as follows:-
The supply is drawn through the suction pipe E from the collecting reservoir F into
the suction chamber J, which is provided with a non-return valve.
On the downstroke of the hollow pump rod, the non-return valve closes, and delivery
valve at bottom of pump rod opens, the lubricant passing through the pump rod C,
[Price 6d.]

page_text: into the perforated tube D, through the perforations, and finally discharged on the
piston rod guides, or other surfaces, the lubricant flows into the collecting boxes H;
from thence through the return pipes M to the receiving reservoir G, through the
connecting pipe N, to the collecting reservoir F, where it is ready again for use.
Having now particularly described & 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. Priority for the entire arrangement substantially as described.
2. Priority in the use and adaptation of a pump either like the one described, or
otherwise, for the purpose of lubricating piston rod guides, and other surfaces.
3. Priority in the use and adaptation of a perforated tube, either as described, or
otherwise, for the purpose of percolating the lubricant on the piston rod guides, or
other surfaces.
4. Priority in the arrangement by which the lubricant after being used on the
piston-rod guides, or other surfaces is conveyed to a vessel, where it becomes clarified,
& then used over again.
