PROVISIONAL SPECIFICATION.
Improvements in and relating to Lubricators for Engine
Cylinders.
1, JOSEPH PICKLES of 5, Lee Street Burnley, in the County of Lancaster, Engineer,
do hereby declare the nature of this invention to be as follows:-
Lubricators at present in use are generally made to discharge their contents into
the engine cylinder, in limited quantities and without regard to any part of the stroke
of the engine. The greater portion of the lubricant is therefore carried away by the
exhaust an the frictional surfaces are only indifferently lubricated.
The object of this invention is to discharge the lubricant into the engine cylinder
"during the lap" that is to say when the exhaust port or passage is closed. A brass
cylinder provided with a cock may be used for filling in the oil or lubricant, and
with another cock which is opene by the action of the piston or from a tappet or the
like fixed on any moving part of the engine or shafting, in such a manner, as to
open the cock tap and only admit the lubricant during the lap and not so as to admit
oil or lubricant when the exhaust port is opened as is now the case with other
lubricators.

COMPLETE SPECIFICATION.
Improvements in and relating to Lubricators for Engine
Cylinders.
I, JOSEPH PICKLES of 5 Lee Street, Burnley, in the County of Lancaster, Engineer,
do hereby declare the nature of this invention and in what manner the same is to
to be performed, to be particularly described and ascertained in and by the following
statement :-
Lubricators at present in use are made to discharge their contents into the engine
cylinder in limited quantities, and without regard to any particular part of the stroke
of the engine. The greater part of the lubricant is therefore carried away by the
exhaust; the frictional surfaces being only indifferently lubricated.
The object of this invention is to discharge the lubricant into the engine cylinder,
during the "lap," that is to say, when the exhaust port or passage is closed.
And in order that my invention may be properly understood and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings
marked with figures and letters of reference, the same letters referring to the same
parts in the various figures.
Fig. 1 is a front elevation partly in section, and Fig. 2 an end view of a lubricator
for steam engines, constructed in accordance with my invention.
In my improved lubricator the oil or other lubricant is contained in an oil cup or
vessel A, which is preferably provided with a measure B, a section of which is shewn
in Fig. 3. This measure after receiving a supply of oil from the oil-cup or vessel A,
and revolving within the casing B³, and being actuated slowly through the medium
of the pawl C, ratchet wheel D, worm E and worm wheel F, tixed to the neck B¹ of
the measure, discharges its contents into the vertical pipe G at intervals, say an hour
for each interval. The oil or like lubricant is then drawn through the seating of the
clack H by the upward stroke of the plunger I, which is connected by link K to the
weigh beam or other suitable moving part of the engine.

page_text: The ram or plunger I is provided with a stuffing gland m, which is screwed down
so as to cause the packing to exert sufficient friction upon the ram or plunger as to
retain it in its elevated position. With the reverse movement of the reciprocating
arm, J, the pin or point of connection to the link I travels in the space of the slot n,
whilst the exhaust port is open, but arriving at the termination of the slot, it then
depresses the ram or plunger J forcing the oil or lubricant forward into the engine
cylinder, through the seating of the clack or valve O, against the pressure of steam,
and during the "lap" or whilst the exhaust port is closed. An additional valve P
may be used if desired to prevent more effectually the escape of steam to the
lubricator.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The arrangement of lubricators substantially as described for the purpose set
forth.
