Improvements in Lubricators for Engines and the like.

page_text: Improvements in Lubricators for Engines and the like.
I, RALPH WRIGHT, of Ismailoffsky Manufactory, Moscow, in the Empire of
Russia, Engineer, do hereby declare the nature of this invention to be as follows:--
My invention relates to improvements in lubricators for engines and the like.
My improved lubricator consists of a pump the piston or ram of which receives
a reciprocating motion from any convenient moving part of the engine. The
barrel of this pump has on one side two delivery orifices communicating with the
part to be lubricated and on the other side two feed orifices in connection with
a reservoir containing the oil or other lubricant all four orifices being controlled
by non-return valves. As the pump piston moves in one direction it draws in
lubricant from the reservoir through one feed orifice and forces out the lubricant
already in the barrel through one of the delivery orifices and on the return stroke
it draws in lubricant through the other feed orifice and discharges the lubricant
already in the barrel through the other delivery orifice.
By this construction I obtain a constant feed and continuous discharge of lubri-
cant so long as the pump piston is working, an advantage not hitherto obtained
so far as I am aware in this class of lubricators.

Improvements in Lubricators for Engines and the like.
I, RALPH WRIGHT, of Ismailoffsky Manufactory, Moscow, in the Empire of
Russia, 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 improvements in lubricators for engines and the like.
My improved lubricator consists of a pump the piston or ram of which receives
a reciprocating motion from any convenient moving part of the engine. The
barrel of this pump has on one side two delivery orifices communicating with
the part to be lubricated and on the other side two feed orifices in connection with
a reservoir containing the oil or other lubricant all four orifices being controlled

jubricant from the reservoir through one feed orifice and forces out the lubricant

In the accompanying sheet of drawings Fig. I is a sectional elevation and Fig. 2
a plan of my improved lubricator for engines or the like.
In these views,-2 denotes a pump barrel and 3 its piston or ram provided with
a slotted head; on one side of the barrel of the pump are two delivery orifices 4, 5
communicating with the part of the engine to be lubricated by passages not shown
and in each orifice is fitted a non-return valve 6, 7 respectively; on the other side
of the pump barrel are two feed orifices 8, 9, which are controlled by non-return
valves 11, 12 respectively and are connected to the pump barrel by pipes bearing
the same reference numbers and also to a reservoir, not shown, containing the
oil or other lubricant.
There is a stuffing box 13 for the rod of the pump piston 3 and a suitable cap 14
to close the opposite end of the pump barrel.
When the piston 3 is moved in one direction a partial vacuum is formed in
the barrel which causes say the valve 11 to open and allow oil from the reservoir
to flow through the orifice and passage 8 into the barrel and when the motion
of the piston is reversed the oil thus admitted is forced through the passage 4 and
valve 6 to lubricate part of the engine and simultaneously oil is drawn into the
pump barrel from the reservoir through the valve 12 and passage 9 which oil on
the return stroke of the piston 3 is forced through the passage under the valve 7
from which it is led to fubricate the engine, oil being simultaneously drawn from
the reservoir through the valve 11 and passage 8 as already described.
By this construction I obtain a constant feed through the passages 8 and
and
a continuous discharge of lubricant through the passages 4 and 5 so long as the
pump piston 3 is working, an advantage not hitherto obtained as far as I am
aware.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
In a lubricator for engines and the like-
1. The combination with a pump, barrel and a reciprocating piston, of connec-
tions and passages fitted with non-return valves so arranged that a continuous
discharge of lubricant is maintained so long as the pump piston is working.
2. The combination with the pump barrel and its piston, of two inlet passages
for supplying the opposite ends of the barrel with lubricant and two outlet passages
for the discharge of the same, all said passages being fitted with non-return valves
and being arranged substantially as and for the purposes herein described with
reference to the accompanying drawing.
