I, JAMES WALKER, of 4 America Square, Minories, London in the county of
Middlesex, Engineers' Furnisher do hereby declare the nature of my said invention
to be as follows:-
The invention is intended to meet the requirements of Electrical Machinery, by
which invention the oil Cup or Lubricator is insulated from the Electricity as
follows construct a Lubricator of Glass with two Chambers, the top one acts as
a reservoir for the oil to which is attached a cap or cover, with valve fastened at
the bottom, through the cap or cover, with valve fastened at the bottom, through the
cap or cover; underneath this reservoir another chamber is formed, the same acting
as a sight, by which the flow of oil can be seen dropping from the valve in the upper
chamber; the mounting or connection is fixed to the lower chamber, which is
screwed to fit the cap of the plummer-block or bearing.
The lower chamber, having no metal connection with the oil reservoir, and being
made of glass, the Electrical Current is broken, thus allowing the lubricator to bo
handled, and refilled with oil, without the risk of an electrical shock. This lubricator
may also be made with one chamber, which has a non-conducting substance between
the cup and the connection with the bearing. The valve is so arranged by an index
that it will discharge any number of drops in a given time, thereby keeping the
bearing well lubricated. The Lubricators may also be fitted for the use of grease.
The Glass may be protected by a frame of metal or any other material.-The oil
Chamber may be arranged so as to admit air-so that by the oil displacement the air
will show the same; a needle may also be used as in ordinary needle Lubricators.
A valve may also be fitted between the bottom chamber and the bearing.

Improvements in Oil Cups or Lubricators.
I, JAMES WALKER of 4 America Square, Minories, London, county of Middlesex,
Engineer and Mill Furnisher, do hereby declare the nature of my 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 Lubricator is intended to meet the requirements of Electric Machinery by
which invention the oilers or Lubricators are insulated from the electricity as
follows: I construct a Lubricator of Glass with two chambers, the top one acts as
a reservoir for the oil, to which is attached a cap or cover with valve fastened at the
bottom. Underneath this reservoir another chamber is formed the same acting as a
sight by which the flow of oil can be seen dropping from the valve in the upper chamber.
The lower glass chamber insulates the cup from electricity, as shown in Fig. I at A.
Then Lubricators may also be made with one chamber Fig. II which has a non-
conducting substance, such as vulcanized fibre, or vulcanite, or any other suitable
material shown at A, insulating the cup from attachment to the machine.
This may also be carried out in the same way in Fig. III mark A. The same may
be fitted to Grease Lubricators as shown in Fig. IV marked A. The valve in Figs. I
11 111 is so arranged to feed the oil at any speed, at the same time it can be shut off,
and again put back exactly where it was, without any further adjustment. This is
done by a spring at B in Figs. 1 II III which keeps the valve () on its seat. The
valve rod at top has a pin at D which can be placed into the graduated steps at E
opening the valve to the height required for the flow of Oil. I is the opening from
the cup into the tube for the oil to flow.
I may also use the insulation to prevent the licat from
glass.
