PROVISIONAL SPECIFICATION.
An Improved Consumption Indicating Lubricator.
JAMES HOGG Brass Founder Bull Ring North Shields Northumberland do hereby
declare the nature of this invention to be as follows:-
I use a cylinder cast or made of brass or other suitable metal. At one end of the
cylinder is fitted valves and or cocks for the purpose of filling and liberating the
supply of oil. At the other end of the cylinder is fitted valves and or cocks for
the purpose of draining the cylinder and supplying the pressure to a piston which is
fitted in the cylinder. This piston has a plane side next the pressure, but the other
side of the piston is fitted with a rod or stem which passes through the stuffing box in
the cylinder cover. To this rod I fix a cross-handle for the purpose of moving the
piston by hand during the operation of filling the cylinder, and a pointer. To the
cylinder I attach an index plate graduated or marked in dimensions for the purpose of
denoting or showing the quantity of oil delivered, or I may fix the index plate to
a stand which I may supply with the Lubricator. It will be seen that by admitting
pressure from the boiler the oil will be forced along with the piston through the
liberating valve to the cylinder or other parts to be lubricated. It will also be seen
that the rod or stem to which is attached the pointer will, on the graduated index,
denote at sight the quantity of oil delivered.

An Improved Consumption Indicating Lubricator.
1, JAMES HOGG of the Bull Ring North Shields, in the County of Durham, Brass
Founder, do hereby declare the nature of said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement :-
The body of the lubricator is a cylinder of brass or other suitable metal having
fitted at one end a valve or cock, or valves or cocks, for filling it and for delivering
the oil where required. The other end of the cylinder is fitted with a valve or cock,
or valves or cocks, to drain the cylinder and also to admit steam, water or air
under pressure from the boiler or pumps behind a piston which is fitted in the
cylinder.
The pressure that I propose to use is that of steam direct from the boilers or air
or water direct from the pumps, in the two former cases acting upon water supplied
by the condensation of steam in a coil or otherwise so as to keep the oil in the
cylinder cool.
The piston I propose to pack with cupped leathers or cupped India rubber rings as
preferable, but packing rings or other means of making it perfectly tight without great
friction may be adopted.
A rod from the piston passes through a stuffing box at one end of the cylinder
having on its outer end a cross handle, for the purpose of moving the piston back
by hand when the cylinder requires refilling with oil, and a pointer on this handle
indicates. on a graduated index plate the quantity of oil which has been delivered
from the cylinder by the pressure of the piston. The graduated index plate may be
fixed to the cylinder or to a separate stand.
"
The cylinder being filled with oil, the valve or cock is opened and the delivery valve
or cock is opened to any required extent, when the body of water next the piston,
and the piston, are forced along the cylinder by the pressure of the steam, air or
water, the pointer on piston rod indicating on the graduated scale the quantity
consumed until the cylinder is empty, when the valve or cock is closed and the drain
valve or cock opened and the piston being forced back to the other end of cylinder
the water of condensed steam is forced out. The oil delivery valvo or cock is now
closed and the filling valve or cock, as also a small air valve, are opened and the
oil is poured into the cylinder when the delivery valve or cock and the steam,
air or water valve or cock are opened and the filling valve or cock and drain valve
or cock are closed and the piston again acts to force out the oil.
On the accompanying drawing Fig. 1 shows a sectional view of the lubricator and
Fig. 2 a portion of a plan looking on top, the lubricator in this instance being
horizontal. A is the cylinder, B the cup into which the oil is poured, C is a two way
cock which admits oil into the cylinder from cup B or delivers oil from the cylinder
into pipe D which conveys it to the engine. E is a two way cock which admits
stean, air or water under pressure through pipe F to act upon the body of water

drain pipe G.
H is the piston shewn packed with cupped leathers J. K is the
piston rod extending outside the stuffing box and fitted with the cross handle M
on which are pointers indicating on the graduated plate N the quantity of oil which
has been consumed by the engine. O is a small air valve to allow the air in cylinder
to escape when the oil is being poured into the cylinder.
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:
A lubricator in which a piston working in a cylinder, packed with cupped leathers
or otherwise, forces the oil through a cock or valve, or cocks or valves, in adjustable
quantity to the engine by the pressure of steam, air or water acting upon a body
of water, interposed between the piston and the pressure, to keep the oil cool, the
position of the piston, and consequently the quantity of oil which has been used,
being indicated by a pointer-upon the end of the piston rod-upon a graduated
index plate, the whole constructed and operating substantially as described and
shewn.
