for the Invention of IMPROVEMENTS IN LUBRICATORS FOR STEAM
CYLINDERS."
"
Sealed the 8th March 1878, and dated the 18th December 1877.
PROVISIONAL SPECIFICATION left by the said Charles Torkington and
James Heyes at the Office of the Commissioners of Patents on the 18th
December 1877.
CHARLES TORKINGTON, of King's Norton, in the County of Worcester, Mill-
wright, and JAMES HEYS, of the same Place, Manager. "IMPROVEMENTS IN
LUBRICATORS FOR STEAM CYLINDERS."
This Invention refers to certain apparatus designed to act as an automatic
lubricator for steam cylinders, and it consists of a lubricating chamber mounted in
a stem by which it is attached to the cylinder; this stem carries also a guage.
Down one side of the chamber runs a port communicating with the cylinder at the
lower end and with the lubricating chamber at the top. Steam from the cylinder is
admitted into the lubricating chamber by this port at the top, and condensing into
water sinks to the bottom, causing the lubricant with which the chamber has
been supplied to float upwards in the state of oil to which the heat of the
steam has reduced it; in this condition it flows over through the port into the
cylinder.
Another improvement consists in the mode of securing the lid or cover on the
lubricating chamber, and this is applicable to other lubricators than ours.
In place
of the screws ordinarily used we employ an eccentric disc worked by a pin to draw
מו

of the steam keeps in position.
To regulate the amount of condensation in the lubricating chamber we prefer to
surround that chamber with steam jacketting.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Torkington and James Heys in the Great Seal Patent
Office on the 17th June 1878.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section through the lubricator.
Figure 2, an elevation of the same.
Figure 3 is a plan of the top of the cover with lid removed.
Figure 4, a plan of the cover and lid.
Figure 5, an elevation shewing another arrangement of the cover.
Figure 6, a plan of half under half upper side of the same.
(a) is the lubricating chamber, to contain suet, grease, plumbago, or other
lubricant, and is surrounded by the steam jacket (b); (c) is the stem by which the
apparatus is attached to the cylinder; (d) are ports communicating with the
chamber (a) and the steam jacket (b). Steam from the cylinder is admitted through
the stem (c) into the jacket (b), and thence into the chamber (a) by the ports (d),
and condensing into water in the chamber (a) sinks to the bottom, floating upwards
the lubricant, which is in a fluid state by reason of the heat from the steam jacket,
until it overflows at the ports (d) into the jacket (b) and thence through the
stem (c) into the cylinder; the pipe (e) is for the purpose of allowing the water
to be blown off when the chamber (a) is full; the tap (f) which is a three-way
tap, is to stop off the steam from the jacket and discharge the same; the
cover (g) which closes the lid through which the lubricant is supplied is worked
by means of an eccentric disc (i) actuated by the handle (h), to which the
disc (i) is pinned, and by the leverage of which handle the disc (i) is worked
in a wedge action against inclined flanges (k) on the upper surface of the cover.
This mode of securing the lid or cover is applicable to other forms of lubri-
cators; is a valve to allow the water to be blown off through the pipe (e).
Figures 5 and 6 shew another arrangement of cover adapted more especially for
fluid lubricants. It consists in a screw working through a cup and provided with a
valve fitting the under side of the cover.

page_text: Having thus described the nature of the said Invention, and the manner in
which the same is to be performed, we claim the improvements in lubricators for
steam cylinders by surrounding the lubricating cup with a steam jacket for the
purpose of regulating the flow and supply in manner herein described; and we also
claim the mode of securing the lid or cover, whether applied to the herein mentioned
form of lubricator or to other forms, as herein more fully set forth and specified.
In witness whereof, we, the said Charles Torkington and James Heys, have
hereunto set our hands and seals, this Fourteenth day of June, in the year
of our Lord One thousand eight hundred and seventy-eight.
