IMPROVEMENTS IN THE CONSTRUCTION OF LUBRICATORS FOR STEAM ENGINES
Year: 1879

page_text: LETTERS PATENT to Ellis Meanock, of Mossley, in the County of Chester, for
the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF LUBRICATORS
FOR STEAM ENGINES."
Sealed the 20th May 1879, and dated the 13th March 1879.
PROVISIONAL SPECIFICATION left by the said Ellis Meanock at the Office of
the Commissioners of Patents on the 13th March 1879.
ELLIS MEANOCK, of Mossley, in the County of Chester.
THE CONSTRUCTION OF LUBRICATORS, FOR STEAM ENGINES."
"IMPROVEMENTS IN
This Invention relates to the construction of lubricators for supplying oil to the
cylinders, valve boxes, or throttle valves of steam engines, for the purpose of lubri-
cating the internal working parts thereof.
.
I employ a vessel or receptacle for the oil placed in any suitable position, and
provided with a small force pump, the suction pipe of which is furnished with a
clack valve at or near the lower end. The plunger of this force pump is attached
to a small lever above, one end of which is acted upon at each stroke of the engine
by a tappet attached to the cross head, or to the valve rod or other suitable moving
part of the engine (or from any revolving shaft), so as to press down the plunger at
each stroke, and force the oil along the delivery pipe. This pipe is carried to the
steam cylinder or other part to be lubricated, where it terminates in a nozzle pro-
vided with a very small opening, near to which also there is a clack valve.
The lever which actuates the plunger is weighted at the end furthest from the
tappet, and on the return stroke of the engine the weight causes the lever to draw
up the plunger, and thus fill the working barrel of the force pump with oil ready
for the next down stroke. Or this action may be reversed, that is to say, the weight
presses down the plunger to force the oil through the delivery pipe, and the tappet
raises the plunger again ready for the next stroke. In this case the position of the
weight may be varied to suit the pressure of the steam to be overcome.

THE CONSTRUCTION OF LUBRICATORS FOR STEAM ENGINES."
"IMPROVEMENTS IN
This Invention relates to the construction of lubricators for supplying oil to the
cylinders, valve boxes, or throttle valves of steam engines, for the purpose of lubri-
cating the internal working parts thereof.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with the following
explanation thereof.
In the annexed Drawing, Fig. 1 is an elevation of my improved apparatus, and
Fig. 2 shows the same on a smaller scale as applied for supplying oil to the valve
box of a steam engine.
I employ a vessel or receptacle a, a, for the oil placed in any suitable position,
and provided with a small force pump b, b, the suction pipe of which is furnished
with a clack valve c at or near the lower end. The plunger d, d, of this force pump
is attached to a small cranked lever e, e*, above, one end of which e is acted upon
at each stroke of the engine by a tappet f, f, attached to the rocking shaft lever g, g,
as shown at Fig. 2, or to the cross-head, or to the valve rod or other suitable moving
part of the engine (or from any revolving shaft), so as to release the lever e, ex, and
allow the weight m to press down the plunger d, d, at each stroke, and force the oil
along the delivery pipe h, h.
This pipe is carried to the valve box i, i, or to the steam cylinder or other part
to be lubricated, where it terminates in a nozzle k (see enlarged view, Fig. 3),
provided with a very small opening, near to which also there is a clack valve l.
The lever e, ex, which actuates the plunger is weighted at the end ex furthest from
the tappet ff, and on the return stroke of the engine the tappet f, f, causes the
lever e to draw up the plunger d, and thus fill the working barrel of the force pump
b, b, with oil ready for the next stroke.
The position of the weight m may be varied so as to suit the pressure of the
steam to be overcome.
Or this action may be reversed, that is to say, the tappet presses down the plunger
to force the oil through the delivery pipe, and the weight raises the plunger again
ready for the next stroke.
n, n, is a float and rod to indicate the level of the oil in the vessel a, a.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention the improved
construction of lubricator herein before described, and illustrated by the Drawing
annexed, or any mere imitation or modification thereof, constructed and operating in
substantially the same or a similar manner.
In witness whereof, I, the said Ellis Meanock, have hereunto set my hand and
seal, this Twelfth day of September, in the year of our Lord One thousand
eight hundred and seventy nine.
