We, DONALD BARNS MORISON of 9, South Crescent Hartlepool in the County of
Durham Engineer and JAMES PATTERSON of The Green Wallsend in the County of
Northumberland, Engineer do hereby declare the nature of this invention to be as

To
Our invention consists in the employment of a small cylinder which is connected
to either or both ends of the cylinder of a steam or other engine so that the piston in
the small cylinder reciprocates with that in the cylinder of the steam or other engine
-this reciprocation of the small piston being utilized to actuate positive lubricators
counters or other apparatus requiring reciprocating motion. In order that our invention
may be fully understood we will explain our improved method of working a positive
lubricator such as requires a reciprocating motion imparted to its driving arm.
obtain this motion we employ a small cylinder and piston, the piston rod being suitably
connected to the driving arm of the lubricator. At each end of this small cylinder a
pipe is led to each end respectively of the cylinder of the main engine so that the
fluid which causes the piston of the main engine to reciprocate aiso acts on the piston
in the small cylinder and so imparts to the driving arm of the lubricator the necessary
reciprocating motion. In the case of the lubricator being of the pump type the plunger
of the pump is preferably in the same line as the piston rod of the small cylinder. If
one end of the small cylinder be connected to one end of the cylinder of the main
engine the necessary return motion may be given to the piston of the small cylinder
by the aid of a spring a weight or other suitable means or instead of the small cylinder
a receiver with a flexible diaphragm may be employed. We do not confine ourselves
to the working of lubricators and counters by this improved means as it may be
adapted to any apparatus requiring reciprocating motion.

Improvements in the Method of Working Positive Lubricators,
Counters, or other Apparatus Requiring Reciprocating Motion.
We, DONALD BARNES MORISON, of 9 South Crescent Hartlepool, in the County
of Durham, Engineer, and JAMES PATTERSON of The Green, Wallsend, in the
County of Northumberland, 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 :-
Our Invention consists in the employment of a small cylinder which is connected
to either or both ends of the cylinder of a steam or other, engine, so that the piston
in the small cylinder reciprocates with that in the cylinder of the steam, or other
engine; this reciprocation of the small piston being utilized to actuate positive
lubricators, counters, or other apparatus, requiring reciprocating motion.
In order that our invention may be fully understood we will explain our improved
method of working a positive lubricator such as requires a reciprocating motion imparted
to its driving arm.
To obtain this motion we employ a small cylinder and piston, the piston rod being
suitably connected to the driving arm of the lubricator. At each end of this small
cylinder a pipe is led to each end respectively of the cylinder of the main engine, so
that the fluid which causes the piston of the main engine to reciprocate also acts on
the piston in the small cylinder, and so imparts to the driving arin of the lubricator
the necessary reciprocating motion. In the case of the lubricator being of the pump
type, the plunger of the pump is preferably in the same line as the piston rod of the
small cylinder. If one end of the small cylinder be connected to one end of the cylinder
of the main engine, the necessary return motion may be given to the piston of the
small cylinder by the aid of a spring, a weight, or other suitable means, or instead of
the small cylinder, a receiver with a flexible diaphragm may be employed. We do not
confine ourselves to the working of lubricators, and counters by this improved means,
as it may be adapted to any apparatus requiring reciprocating motion.
In order that our aforesaid invention, and the manner of performing the same may
be the more readily understood we append two sheets of explanatory drawings shewing
the application of our invention to positive lubricators.
Figures I and II, sheet 1, shew our invention as applied to a positive screw-down
lubricator. A is the cylinder, B and C the inlets for communication with the respec
tive ends of the cylinder of the main engine. D is the piston-rod, by means of which
and the pawl F, the reciprocating motion of the piston is made to act upon the
driving arm or wheel G (which in this case is shewn a ratchet wheel; but it is evident
that any equivalent feed-motion may be employed). By means of the milled nuts H H
the stroke of the piston may be adjusted so as to take one or more teeth of the ratchet
wheel at a stroke.
а
In order that the plunger P may not be driven, through inattention, through the
bottom of the cylinder Q, any suitable arrangement, whereby, when the plunger P

page_text: has descended a certain distance, it strikes a plug or a trigger, or the handle of a
cock, and so shuts off the actuating fluid from the cylinder A, may be used.
Figures III, IV and V sheet 2 shew the application of our invention to a positive
lubricator of the pump type. The steam cylinder A is placed on the same centre-line
as the pump L, and the piston-rod D is continued to form the plunger for the pump.
B and C are the inlets for the connecting pipes to the cylinder of the main engine.
In a similar manner to the above the reciprocating motion of the piston in the
small cylinder may be utilized to give motion to a counter or any other apparatus
requiring a reciprocating motion.
If one of the inlet pipes such as C be omitted, the return stroke may be caused by
a weight suitably applied, or by a spring.
Instead of the cylinder A, a receiver with a flexible diaphragm may be used in cases
where a limited motion is required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
-
(1) The use of a small cylinder, connected at each end, respectively, to each end
of the cylinder of the main engine by means of pipes, or otherwise, for the purpose of
utilizing the reciprocating motion from its piston for actuating lubricators, counters,
or other apparatus requiring or using reciprocating motion, substantially as herein-
before described and illustrated.
(2) The use of a small cylinder as, and for, the purposes previously described,
having only one connection to the cylinder of the main engine and having the return
stroke of the piston caused by a spring or weight, substantially as hereinbefore
described.
(3) The use of a receiver with a flexible diaphragm connected to the cylinder of
the main engine at one or both ends, in place of the aforesaid small cylinder,
substantially as hereinbefore described.
