PROVISIONAL SPECIFICATION.
Improvements in or relating to Lubricating Apparatus.
I, JOHN MILLER, of the firm of Smith Brothers & Co., Hyson Green, in the
Borough of Nottingham, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to lubricating apparatus in which the vessel for containing
the lubricant consists of a cylinder provided with a piston, on one side of which is
the lubricant and on the other side steam is admitted so as to equalize the pressure
on both sides of the piston so that it may be operated with little power.
In carrying out this invention in lubricating apparatus such as described I employ
a weight or weights to operate the piston such weights being preferably adjustable
so as to regulate the delivery of the lubricant as desired; this may be effected in
various ways but preferably by one of the following manners.
The lubricant may be in some cases placed below the piston and the piston rod
carried through a gland in the upper end of the cylinder and provided with a weight
or receptacle for weights at its upper end or the lubricant may be placed above the
piston and the piston raised by chains or cords attached to the piston rod passing
over pulleys and provided with suitable weights.
In some cases the piston rod may be formed with a rack screw or other suitable
arrangement and be operated through suitable connections by a drum or pulley
round which passes a chain or cord to which weights are attached.
Where hanging weights are employed suitable guides may be used for steadying
them or a weight may be formed to encircle the cylinder; in all cases the weights
may be formed of hollow vessels and filled or partly so with liquid so as to regulate
the pressure.
Suitable provision may be made for filling the cylinder with the. lubricant also
for steam inlet and lubricant outlet and the positions of these may be changed to
suit different arrangements of the weights.
By this means a known pressure is employed to force out the lubricant which
force is adjustable at will and can thus be regulated to suit different requirements:

COMPLETE SPECIFICATION.
Improvements in or relating to Lubricating Apparatus.
I, JOHN MILLER, of the firm of Smith Bros. & Co., Hyson Green, in the
Borough of Nottingham, Engineer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention relates to lubricating apparatus in which the vessel for containing
the lubricant consists of a cylinder provided with a piston on one side of which is
the lubricant and on the other side steam is admitted so as to equalize the pressure
on both sides of the piston so that it may be operated with little power.
It will be best understood by reference to the accompanying drawings in which
Fig. 1 is a vertical section and
Fig. 2 is a side elevation showing modification of apparatus constructed according
to this invention.

page_text: In carrying out this invention I employ a weight or weights to operate the piston
the amount of such weights being preferably adjustable so as to regulate the delivery
of the lubricant as desired; this may be effected in various ways but preferably by
one of the following:
:-
The lubricant may in some cases be placed above the piston A. and the piston
raised by a chain or flexible connection B attached to the upper end of the piston
rod C which passes through a gland in the upper end or cover of the cylinder H;
the chain or connection B passes over a pulley E pivotted on a bracket E' secured
to the cylinder and carries a weight F. If desired the weight F may be adapted
to slide in vertical guides so as to steady it or a weight may be formed as shown
at G (Fig. 2) so as to encircle the cylinder H. With this arrangement the weight
is carried at two points by chains B₁ passing over pulleys E2 pivotted on brackets E³
secured to the cylinder and their ends connected to the upper end of the piston
rod C.
The lubricant may in some cases be below the piston A. and a weight or receptacle
for weights secured to the upper end of the piston rod C; or the piston rod may
be formed with or connected to a rack, screw, or other suitable arrangement and be
operated through suitable connections by a drum or pulley round which passes a
chain or flexible connection to which weights are attached. In all cases the weights
may be formed of hollow vessels to contain shot or the like or liquid so as to
regulate the pressure.
Provision is made at I for filling the cylinder or vessel H with the lubricant also
at J for steam inlet, at K for water outlet and at L for lubricant outlet provided
with sight-feed I, the positions of these may however be changed to suit different
arrangement of weights.
By the foregoing arrangement a known pressure can be employed to force out the
lubricant which force is easily adjustable and can thus be regulated to suit different
requirements.
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 the employment of a weight for expelling the lubricant from
the containing vessel substantially as described.
2. In a lubricator the combination with the piston rod of a weight such as For G
and connecting chain or chains and pulley or pulleys substantially as described and
illustrated in Figure 2 of the accompanying drawings.
3. In a lubricator the combination with the containing cylinder or vessel H of an
encircling weight such as C substantially as described and illustrated in Figure 2 of
the accompanying drawings.
4. The combination and arrangement of parts constituting the complete
lubricating apparatus substantially as described and illustrated in Figures 1 or 2 of
the accompanying drawings.
