tion of "IMPROVEMENTS IN MEANS OR APPARATUS FOR LUBRICATING
PROVISIONAL SPECIFICATION left by the said Edmund William
Halliday at the Office of the Commissioners of Patents, with his
Petition, on the 23rd September 1868.
I, EDMUND WILLIAM HALLIDAY, of Saint Peter's Wharf, Hammer-.
smith, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MEANS OR APPARATUS FOR LUBRICATING
CYLINDERS, SHAFTS, AND THE RUBBING PARTS OF MACHINERY GENERALLY," to be.
as follows:-
The Invention has for its object improvements in means or apparatus:
for lubricating cylinders, shafts, and the rubbing parts of machinery
generally. For this purpose I employ a disc or plate working between
two. fixed plates, there being a hole or holes in the moveable disc or.

page_text: plate, which alterately come opposite a hole or holes in one of the fixed
plates, and then opposite a hole or holes in the other fixed plate, one of
such fixed plates forming the bottom of the oil or grease cup or reservoir,
whilst the other is held in position by bolts and nuts, and is kept up to
the moveable plate or disc by means of a spring or springs or other
suitable means; the moveable disc or plate is fixed to and operated by a
rod or shaft, to which motion is given from any suitable part of the
machine or engine. If desired the moving part of the lubricator may
be in the form of a piston or plug having a suitable opening or openings
therein or therethrough, which are alternately brought opposite one
opening and then opposite another opening in the cylinder or seat in
which it works.
The action of the lubricator is as follows:When the moving part
thereof is in one position the opening or openings therein receive the
grease or oil from the cup or reservoir, and then when in another position
the opening or openings in the moving part are in position to discharge
the oil or grease into the steam pipe to be conveyed to the valves, and
thence to the cylinder; or the grease or oil may be discharged or supplied
to the bearings or other parts, desired to be lubricated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,.
filed by the said Edmund William Halliday in the Great Seal
Patent Office on the 23rd March 1869..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND,
WILLIAM HALLIDAY, of Saint Peter's Wharf, Hammersmith, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of September, in tho
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edmund William Halliday,
Her special licence that I, the said Edmund William Halliday, my
executors, administrators, and assigns, or such others as I, the said
Edmund William Halliday, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and

page_text: lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN MEANS OR APPARATUS FOR LUBRI-
CATING CYLINDERS, SHAFTS, AND THE RUBBING PARTS OF MACHINERY GENERALLY,"
upon the condition (amongst others) that I, the said Edmund William
Halliday, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Edmund William Halliday, 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 thereof, that is to say :-
The Invention has for its object improvements in means or apparatus
for lubricating cylinders, shafts, and the rubbing parts of machinery
generally. For this purpose I employ a disc or plate working between
two fixed plates, there being a hole or holes in the moveable disc or
plate, which alternately come opposite a hole or holes in one of the fixed
plates, and then opposite a hole or holes in the other fixed plate, one of
such fixed plates forming the bottom of the oil or grease cup or reservoir,
whilst the other is held in position by bolts and nuts, and is kept up to
the moveable plate or disc by means of a spring or springs or other
suitable means; the moveable disc or plate is fixed to and operated by
a rod or shaft, to which motion is given from any suitable part of the
machine or engine.
The action of the lubricator is as follows:-When the moving part
thereof is in one position the opening or openings therein receive the
grease or oil from the cup or reservoir, and then when in another position
the opening or openings in the moving part are in position to discharge
the oil or grease into the steam pipe to be conveyed to the valves and
thence to the cylinder; or the grease or oil may be discharged or supplied
to the bearings or other parts desired to be lubricated.
And in order that my Invention may be more clearly understood and
readily carried into effect I will proceed, aided by the accompanying
Drawings, more fully to describe the same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of lubricating apparatus constructed
according to my Invention; Figure 2 is a sectional under side view
taken on the line 1, 1, of Figure 1; Figures 3 and 4 are views of some
of the parts separately.
a is a disc or plate having a number of holes a¹ formed therethrough;
this disc or plate a is connected by a pin a² or other suitable means to
the rod or shaft b working in suitable bearings formed for it in the top c¹
and bottom of the grease cup or reservoir c. The disc or plate a is
caused to work between the bottom of the grease cup or reservoir c
and the fixed plate d, the surfaces of these parts being made accurately
to fit together, so that when ready for working they shall be perfectly
steam-tight, and thereby effectually shut off all communication between
the steam and the grease cup or reservoir c. In the bottom c³ of the
grease cup or reservoir c is formed a hole c³, and in the plate d a similar
hole d¹ is formed, such holes and d¹ being at different sides of the rod
or shaft b. The plate d is held in position by means of a spring e and
bolts and nuts f, as shewn, or by other suitable means, the spring e
acting constantly to press such plate d upwards towards the disc or
plate a. To the bottom of the grease cup or reservoir c is fixed a
chamber g, which is provided with a screw thread g', as shewn, in order
to facilitate connection of the apparatus to any part desired to be lubri-
cated. When such apparatus is fixed in such position as to permit the
free access of steam to the chamber g, tallow or other hard grease may
be employed. The rod or shaft 6 may be operated, as shewn in the
Drawings, by means of any suitable connection from the engine or
machine working the lever carrying a click or driver h¹ to act on the
ratchet wheel i keyed or otherwise fixed on the top of the rod or shaft b,
or such rod or shaft b may be operated by other suitable means.
The action of the lubricator is as follows:-As the holes a¹ in the disc
or plate a come opposite the hole in the bottom of the grease cup or
reservoir c they receive a supply of grease or oil, and then as such
holes a¹ come opposite the hole d¹ in the fixed plate d they discharge the
grease or oil into the chamber g, whence it flows through the opening g'
to the part desired to be lubricated. If desired the disc or plate a may
be mounted in guides and receive a to-and-fro motion in a similar
manner to the slide valve of an engine, or the moving part may be in

page_text: the form of a piston or plug having a suitable opening or openings
therein, which are alternately brought opposite one opening, and then
opposite another opening in the cylinder or seat in which it works, as
will be readily understood.
Having thus described the nature of my Invention, and the manner in
which I carry the same into effect, I would have it understood that I do
not confine myself to the preciso details herein shewn and described;
but what I do claim is, the novel combinations and arrangements of
means or apparatus for lubricating cylinders, shafts, and the rubbing parts
of machinery generally, substantially as herein shewn and described.
In witness whereof, I, the said Edmund William Halliday, have
hereunto set my hand and seal, this Twenty-third day of March,
in the year of our Lord One thousand eight hundred and sixty-
nine.
