MECHANICAL LUBRICATORS
Year: 1886

page_text: JOHN THOMAS HEDLEY, 17, Shield Field Green Newcastle upon Tyne Brass-
finisher do hereby declare the nature of my invention for MECHANICAL
LUBRICATORS to be as follows:-
The mechanical lubricator will have, a solid ram A with valves B. & C. arranged,
works through a stuffing box I at one end. By lever D and fulcrum E. The lever
to be connected to any moving part of engine, and the stroke of ram to be
adjusted by holes shown in lever D. an open reservoir with loose cover, and sight
feed regulating valve F. and self closing.
A glass tube in × 2 where the oil drops through fits in recesses with india
rubber faces.
The nut G. on regulating valve is screwed down and secures it, preventing dust
and any tampering with valve B: it can be put in and taken out at any time, by
screwing nut G. back.
The outward stroke of ram opens valve B. and valve C. shuts, on the inward
stroke of ram it shuts valve B. and forces the oil it received on the outward stroke
from valve B. through valve C. to the steam pipe, or steam chest, or any part to
be lubricated.
と
When the engine stops, the pressure is always on valve B. and keeps it shut, so
it is not necessary to shut drop valve off when once regulated and can be regulated
from a drop to any required supply.
•
The outlet H. can be placed where the flange J. is if required.
The lubricator to be applied to high and low press'd steam and hydraulics, and
can be worked by any moving or convenient part of engine or by hand.

JOHN THOMAS HEDLEY, Brass Finisher 35 Hull Street Bentinck (Late 17, Shield
Field Green) Newcastle-upon-Tyne do hereby declare the nature of my invention
for IMPROVEMENTS IN MECHANICAL LUBRICATORS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The lubricator having an open reservoir with regulating sight feed valve F and
nut G. for securing glass tube, a solid ram A. worked by lever D connected to
fulcrum E. through stuffing box I. self closing outlet valve C. and outlet H.
Flange J. for fixing lubricator, to be worked by any moving or convenient part of
engine or machine, the stroke of ram to be adjusted by holes shown in lever D
On the outward stroke of ram valve B opens, and on the return stroke valve B
shuts, and forces the oil it received from valve B through valve C to outlet H,
to the part or parts to be lubricated. The reservoir may be made any size, the
regulating valve can be regulated from one drop, to any required supply, and when
once regulated requires no further attention. If the engine or machine stops it
cannot run over or waste, valve C. is always shut (by spiral spring attachment)
and fills the glass tube which only holds a few drops, and the moment the engine
or machine starts, the ram draws the lubricant out of the glass tube through
valve B. and forces the lubricant on the inward stroke through valve O. to
outlet H. to the part or parts to be lubricated. In the sight feed valve arrange-
ment the glass tube fits in recesses with india rubber or other faces, the nut G.
secures it, it being recessed as shown, and is screwed down on face of tube, the
glass tube can be taken out at any time, or will work with or without it, the tube
prevents dust or waste of oil, or any tampering with valve B. the lever can be
turned round to catch any moving or convenient part of engine or machine, by
screwing nut back which keeps fulcrum in its place.
Having now particularly described and illustrated the nature of my Inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
First. The use of a mechanical lubricator having a solid ram, for forcing oil or
other lubricant, to be applied to steam, gas, air, hydraulics and other motive power
engines, as described and illustrated.
Second. In a mechanical lubricator having a regulating sight feed valve with
glass tube fit in recesses, and nut G. for securing the same, with self closing valve C.
with spiral spring attachment as described and illustrated.
Third. The combination and arrangement as here described and illustrated in
drawings forwarded with Complete Specification.
