PROVISIONAL SPECIFICATION left by the said Henry David Furness
at the Office of the Commissioners of Patents, with his Petition,
on the 15th September 1871.
I, HENRY DAVID FURNESS, of Whickham, in the County of Durham,
Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED METHOD OF LUBRICATING THE CYLINDERS AND VALVES OF
LOCOMOTIVE AND OTHER ENGINES," to be as follows:-
This Invention relates to an improved method of lubricating the
cylinders and valves of locomotive and other engines by combining the
use of a cup or reservoir and a receiver for containing lubricating matter
(such as oil), which is conveyed from the reservoir to the receiver by
1

page_text: capillary attraction through a wick or by other like means. Tlie receiver
communicates with the cylinder, the valve chest, or the steam pipe by
means of conduits or tubes, which communication is cut off or opened
by means of a self-acting valve (that closes by gravitation and opens by
atmospheric pressure), preventing the admission of steam into the
receiver or reservoir, and opening to admit a portion of oil or lubricating
matter to the cylinders and valves only when the engine is in motion
after the steam is cut off, but under no other circumstances, a small
portion of oil passing over at every stroke.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry David Furness in the Great Seal Patent
Office on the 15th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
DAVID FURNESS, of Whickham, in the County of Durham, Engineer,
send greeting.

thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry David Furness,
Her special licence that I, the said Henry David Furness, my executors,
dministrators, and assigns, or such others as I, the said Henry David
Furness, 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 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
"AN IMPROVED METHOD OF LUBRICATING THE CYLINDERS AND VALVES OF
LOCOMOTIVE AND OTHER ENGINES," upon the condition (amongst others)
that I, the said Henry David Furness, my executors or administrators,

page_text: by an instrument in writing under my, or their, or one of their hands
and seals, should particularly 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 Henry David Furness, do hereby
declare the nature of the 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:
•
This Invention relates to an improved method of lubricating the
cylinders and valves of locomotive and other engines by combining the
use of a cup or reservoir and a receiver for containing lubricating matter
(such as oil), which is conveyed from the reservoir to the receiver by,
capillary attraction through a wick or by other suitable means.. The
receiver communicates with the cylinder, the valve chest, or the steam
pipe by means of conduits or tubes, which communication is cut off or
opened by means of a self-acting valve (that closes by gravitation and
opens by atmospheric pressure), preventing the admission of steam into.
the receiver or reservoir, and opening to admit a portion of oil or
lubricating matter to the cylinders and valves only when the engine is
in motion and the steam is cut off, but under no other circumstances, a
small portion of oil passing over at every stroke.
The apparatus containing the conduits or tubes and gravitation valve,
together with the receiver, can be varied in form and construction so as:
to be screwed into any existing oil cup or reservoir.
i
And in order that my Invention may be, more fully understood and
readily carried into practice, I will proceed to describe the Drawings
hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
The Drawings show three different forms and arrangements of
apparatus for lubricating the cylinders of locomotive and other engines,
arranged and constructed so as to act in accordance with my improved,
method of lubricating. The parts which are common to cach form of.
apparatus shown in the Drawings are marked with corresponding letters.
of reference in all the Figures, so that it will not be necessary to repeat,
the description of cach of such parts separately.
i

page_text: A is an oil cup or reservoir, which may be made of glass, metal, or
other suitable material, and the form and method of combining it with
the other parts of the apparatus may be greatly varied, as shown by
the three examples given. B is the receiver into which the oil or other
lubricating matter is fed gradually from the reservoir by means of a
syphon of cotton wick M or other fibrous material, or by any other
suitable means. The receiver B may form part of the reservoir A,
as shown in Figure 1, or it may be combined therewith, as shewn in
Figures 3 and 6, and the reservoir and parts connected therewith may
either be fixed by a screw or other joint direct on to the cylinder, valve
chest, or steam pipe, as shewn in Figure 3, or the parts may be formed
separately and applied as shewn at Figures 1 and 6, or the parts may be
otherwise arranged and combined to adapt the lubricating apparatus to
the particular purpose for which it is required. E is a tube or conduit
communicating with the cylinder or valve chest by means of the valve F
and conduit or tube G, connecting or placing it in communication with
the receiver and oil vessel or reservoir A. H is a screw cap or cover, by
removing which the valve F is easily accessible. L is a plate or cover,
by opening which oil or other lubricating matter can be introduced into
the reservoir A.
In Figure 1 T is a stop-cock, and in Figure 3 T* is a screw stop
valve for cutting off the communication between the cylinder, valve
chest, or other part and the receiver B.
In the arrangement of apparatus shown by Figures 1 and 2 the
reservoir A or receptacle for the oil is placed at a distance from the
conduit or tube E leading to the cylinder or valve box for the purpose
of keeping the oil cool, and in the arrangement shown by Figures 3,
4, and 5 an air space X is arranged between the reservoir A and the
tube or conduit E for the same purpose.
In the arrangement shown by Figures 6 and 7 the conduit G is
arranged so as to act also as a reservoir,
The action of the apparatus is as follows:-The oil or lubricating
matter contained in the reservoir A (up to any height below the top of
the receiver B) is gradually conveyed by the wick or syphon M into the
receiver B, and when the engine is at rest the valve F remains closed
by its own gravity. When the engine is in motion the steam passes up
the tube or conduit E, and is prevented from entering the receiver B or

page_text: reservoir A by the valve F, but when the steam is cut off a partial
vacuum is formed above the valve F, thus causing it to open, and the
oil collected in the receiver B. is drawn into the cylinder, steam chest,
pipe, or passage to which the apparatus is applied. In like manner all
the oil which is conducted from the reservoir to the receiver by the wick
or syphon is successively drawn in until the engine stops or steam is
turned on.
In either case the valve F closes and cuts off the com-
munication between the receiver and cylinder or other part to which the
apparatus is applied.
The valve F in each arrangement is prevented from rising above a
determined height by coming against the cover H.
-
Having thus described the nature of my Invention, and the manner
of carrying the same into practice, I would have it understood that I do
not confine myself to the particular arrangements and construction of
apparatus shown in the Drawings, as the same may be greatly varied
without departing from the true character of my Invention; at the same
time I would remark that I do not claim the use of a wick or syphon,
nor the action of the same in combination with a valve; but what I do
claim is, the improved method of lubricating the cylinders and valves of
locomotive and other engines by means of apparatus arranged in com-
bination with a self-acting valve F, which opens and closes in such
manner that the oil is conveyed from a reservoir A to a receiver B,
and is only admitted to the cylinder or slide valves when the engine is
in motion and the steam is cut off, substantially as herein-before
described and shewn in the Drawings hereunto annexed.
In witness whereof, I, the said Henry David Furness, have hereunto
set my hand and seal, this Eleventh day of March, in the year
of our Land One thousand sight hundred and
