Improvements in and in connection with Lubricators.
MARK HENRY SCOTT, 4, Sidney Road, Forest Gate, Essex, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention is to automatically force grease on to any moving surface of
machinery for the purpose of lubricating same, the delivery of which can be
stopped when the machinery is not in motion.
It consists of a cylinder, cup, or box, as a grease receiver the grease being forced
to its destination by means of a coil spring operating on a nut or sleeve which
revolves around the spindle or screw of a piston driving the piston forward thus
forcing the grease through the outlets in bottom or end of cylinder.
In connection with this lubricator is a folding link joint which is made to
follow of a crank pin, cross head, eccentric or the like:—from a fixed centre,
where the lubricator may be attached so as to enable it to be refilled when the
machinery is in motion.
It consists of a hollow male & female socket, oscilating, one within the other;
the joint being kept tight by expanding segments & soft packing as hereinafter
described.
The lubricator as shown in Fig. 1 Sheet 1, is fitted with one, or more, valves at
bottom or end of same to controle & regulate the delivery of lubricant.
A handle is fitted so as to draw back the piston previous to recharging the
same operation rewinds coil spring, which operates on the piston as aforesaid.
The coil spring can be wound with seperate action if desired as shown in Figs. 4
& 5 on Sheet 1.
The handle can also be used as a means of forcing an extra amount of grease
through cylinder if required.
The delivery of lubricant can be stopped by closing the valve H1, Fig. 1, or by
throwing in the check pawl, b, Fig. 2, which resists the action of coil spring.
The amount of lubricant in cylinder is indicated by the position of piston screw,
or spindle.

MARK HENRY SCOTT, 4, Sidney Road, Forest Gate, Essex, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:.
-
This invention is to automatically force grease on to any moving surface of
machinery for the purpose of lubricating same, the delivery of which can be
stopped when machinery is not in motion in the manner hereinafter described. It
consists of a cylinder cup or box as a grease receiver, the grease being forced to
its destination by means of a coil spring operating on a nut or sleeve which revolves
around the spindle or screw of piston driving the piston forward, thus forcing the
grease through the outlets in bottom or end of cylinder. In connection with this
lubricator is a folding link or joint which is made to follow the motion of a crank
pin, crosshead, eccentric or the like, from a fixed centre where the lubricator may
be attached, so as to refill when the machinery is in motion. It consists of a
hollow male & female socket osscilating one within the other, the joint being kept
tight by expanding segments or wedges & soft packing as hereinafter described.
The lubricator as shewn in Fig. 1, Sheet (1.) is fitted with one or more valves
at bottom or end of same to control & regulate the delivery of lubricant.
A wheel handle is fitted so as to draw back the piston previous to recharging;
the same operation rewinds coil spring which operates on the piston as aforesaid.
The coil spring can be wound with separate action if desired as shewn in Figs. 4
& 5 on Sheet (1).
A wheel handle can also be used as a means of forcing an extra amount of
grease through cylinder if required.
The delivery of lubricant can be stopped by closing the valve H1, Fig. 1, or
by throwing a check pawl in L. Fig. 2, which resists the action of coil spring.
The amount of lubricant in cylinder is indicated by the position of piston screw
or spindle.
The drawings supplied are as follows.-

Fig. 1, is a sectional elevation of the lubricator as generally described.
Fig. 2 is a plan of same.
Fig. 1. A, is the cylinder or grease receiver.
B, is a screwed cap to which the parts are fitted & could be made solid with A
if desired.
