sealed the 23rd June 1874, and dated the 24th April 1874.
COMPLETE SPECIFICATION filed by the said David Jones at the Office
of the Commissioners of Patents, with his Petition and Declaration,
on the 24th April 1874, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
JONES, of Millburn, Inverness, in the County of Inverness, Mechanical
Engineer, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
LUBRICATING CYLINDERS AND VALVES OF STEAM AND OTHER ENGINES," and have
petitioned Her Majesty to grant unto me, my executors, administrators,

page_text: and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that I am the true and first Inventor thereof.
NOW KNOW YE, that I, the said David Jones, do hereby declare that the
following Complete Specification, under my hand and seal, fully describes
and ascertains the nature of the said Invention, and in what manner the 5
same is to be performed in and by the following statement :—.
The object intended to be accomplished by my said Invention is the
peculiar and important one of providing a lubricator, cup, or reservoir
having a small area opened to the cylinder or valve, and covered by a
pad or retarder regulating the quantity of lubricant to the cylinder or 1
valve, such lubricator, cup, or reservoir capable of being made without
either valve or cock, as shewn, and of any suitable dimensions, and so
that the top cover makes a steam-tight joint.
The means whereby I carry out the said object and Invention consist
in constructing a lubricator, cup, or reservoir for containing lubricating 1
matter such as oil or tallow, which is conveyed from the lubricator, cup,
or reservoir to the cylinder or valve by a partial vacuum at each stroke
of the piston.
Having thus described and ascertained the nature of my said Inven-
tion, and intimated in what manner the same is to be performed, I will 2
now proceed to more fully and particularly describe and ascertain in
what manner the same is to be performed or carried out in practice,
which I shall do by referring to the accompanying Drawings (craving
the aid (if necessary) of the foregoing statements) as follows:-
Fig. 1. is an elevation my improved lubricator, cup, or reservoir;
Fig. 2, a section; and Fig. 3, pad or retarder; Fig. 4, a partition; Fig.
5, perforated disc plates; Fig. 6, a key.
These Drawings show the apparatus for lubricating cylinders or valves
of steam and other engines, arranged and constructed so as to act in 30
accordance with my improved method of lubricating.
In the Drawings A is a lubricator, cup, or reservoir; B, partition with
small area in it opened to cylinder or valve, and where the perforated
disc plate O is screwed into; D, the cover; E, is the pad or retarder;

page_text: F, the key to screw the disc plate C, more or less, all of which may be
made of any suitable material.
Having now particularly described and ascertained the nature and
object of my Invention and in what manner the same is to be performed
or put in practice, I hereby declare that I claim the herein designated
Invention of "Improvements in Lubricating Cylinders and Valves of
Steam and other Engines," as herein-before described, wherein important
features are the adoption and use of the construction of lubricator, cup,
or reservoir to the cylinder or valve, which operates by partial vacuum
at each stroke of the piston with small area opened to the cylinder or
valve, covered by a pad or retarder regulating the quantity of lubricant
to the cylinder or valve.
to the cylinder or valve.
In witness whereof, I, the said David Jones, have hereunto set my
hand and seal, this 14th day of April in the year of our Lord One
thousand eight hundred and seventy-four.
Witness,
GEO. W. REID,

Inverness.
