St., Adelphi, in the Parish of St. Martin's in the Fields, Co.
Middlesex, Consulting Engineer for Patents, for the Invention of
"IMPROVEMENTS IN LUBRICATORS."-A communication from abroad by
David Adamson of Bremen
Germany Engineer
PROVISIONAL SPECIFICATION left by the said Charles Frederic
Trelawny Young at the Office of the Commissioners of Patents,
with his Petition, on the 1st August 1870.
I, CHARLES FREDERIC TRELAWNY YOUNG, of 7, Duke St., Adelphi,
in the Parish of St. Martin's in the Fields, Co. Middlesex, Con-
sulting Engineer for Patents, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LUBRICATORS," to be as follows:-
This Invention has for its object to provide a lubricator cup which
can be used on all kinds of machinery, but more particularly upon high-
pressure engines, with any suitable viscid or other lubricating material,

page_text: and consists in the arrangement of a cylindrical cup which contains a
piston, to the upper or outer surface of which steam pressure is or can
be applied. The advantages of this lubricator or cup are, first, that it can
be applied in a horizontal as well as a vertical position; secondly, that
it can be used with viscid or coagulating lubricating material; and,
thirdly, that by regulating the steam pressure the flow of lubricating
material can also be easily regulated. The lubricator cup is cylindrical
in form and is supported by a hollow stem, shank, or support which is
secured in the requisite position to the machinery. Within this cup is
placed a close piston which is inserted when the screw cup or cover of the
same is removed; and after the lubricating material has been inserted. The
stem of this piston may be made to project through the cup, in which
case a steam-tight packing is applied to the same. A steam pipe enters
the cup between its cover and the piston herein-before described, and
the steam admitted through the same into the cup will force the lubri-
cating material into the hollow stem, shank, or support, and thence to
the desired position. The flow of steam is regulated by a cock in the
pipe, and that of the lubricating material by another cock placed in the
hollow stem or shank herein-before described. The lubricating material
may be petroleum residue or other viscid or coagulating material. The
latter kind can only be made liquid by heat, and the outer pressure for
forcing it out of the cup will aid considerably in its application..
A modification of my Invention consists in providing a steam entrance
through the screw shank of the cup, so that the steam pressure will be
applied against the lower side of the piston. The lubricating material
will be forced by such upward pressure into the upper end of a pipe
which extends from the upper part of the cup to the lower end of its
shank. By this arrangement I obtain a more even and less forcible
action upon the lubricating material, besides facilitating the application
of a valve for regulating the flow of the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Frederic Trelawny Young in the Great
-Seal Patent Office on the 28th January 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
FREDERIC TRELAWNY YOUNG, Consulting Engineer of Patents, of 7,

page_text: Duke Street, Adelphi, in the Parish of St. Martin's in the Fields, in the
County of Middlesex, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of August, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-fourth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Charles Frederic Trelawny Young, Her special licence
that I, the said Charles Frederic Trelawny. Young, my executors,
administrators, and assigns, or such others as. I, the said Charles
Frederic Trelawny, Young, 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 “IMPROVEMENTS IN Lubricators,” being a com-.
munication to me from abroad by David Adamson, of Bremen, Germany,
Engincer, upon the condition (amongst others) that I, the said Charles.
Frederic Trelawny Young, my executors or administrators, by an
instrument in writing under my, or their, or one of their hand
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 Charles Frederic Trelawny Young, 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, and accompanying Sheet of
Drawings:-
This Invention has for its object to provide a lubricator cup which
can be used on all kinds of machinery, but more particularly upon
high-pressure engines with any suitable viscid or other lubricating
material, and consists in the arrangement of a cylindrical cup which
contains a piston to the upper or outer surface steam pressure is or
can be applied. The advantages of this lubricator or cup are, first,
that it can be applied in a horizontal as well as a vertical position;
second, that it can be used with viscid or coagulating lubricating

page_text: material; and, thirdly, that by regulating the steam pressure the flow of
lubricating material can also be easily regulated. The lubricutor or cup
is of a cylindrical or other suitable form, and is supported by a hollow
stem, shank, or support, which is secured in the requisite position to
the machinery requiring to be lubricated. Within this cup is placed
a close fitting piston which is inserted when the screw cap or cover
of the same is removed, and after the lubricating material has been
inserted. The stem of this piston may be made to project through the
cap, in which case a steam-tight packing is applied to the same. A
steam pipe enters the cup between its cover and the piston herein-before
described, and steam admitted through the same into the cup will force
the lubricating material into the hollow stem, shank, or support, and
thence to the desired position. The flow of steam is regulated by a cock
in the pipe, and that of the lubricating material by another cock placed
in the hollow stem or shank. The lubricating material may be petroleum
residue or other viscid or coagulating material. The latter kind can
only be made liquid by heat, and the steam pressure for forcing it out of
the cup will aid considerably in its application.
A modification of my Invention consists in providing a steam entrance
through the screw shank of the cup so that the steam pressure will be a
applied against the lower side of the piston. The lubricating material
will be forced by such upward pressure into the upper end of a pipe
which extends from the upper part of the cup to the lower end of its
shank. By this arrangement I obtain a more even and less forcible -
action upon the lubricating material, besides facilitating the application
of a valve for regulating the flow of the same.
DESCRIPTION OF THE DRAWINGS.
(Fig. 1) represents an elevation and part broken away to shew the
interior of the lubricator or cup first named herein. A, A, the lubri-
cator cup; B, the piston, partly in elevation and partly dotted; C, the a
screw cap or cover; D, D, the steam pipe for admitting the steam to act

page_text: packing; ff, the tube, passage, or outlet through which the lubricating
material passes; g, lubricating material.
(Fig. 2) represents the modification of the lubricator or cup herein-
before described. A, A, the lubricator cup; B, B, the moveable piston
fitted with the steam-tight packing H and I, I, and sliding on the
tube D, D; C, C, the screw cap or cover; D, D, the tube or pipe
through which the lubricating material passes to the passage c, c, and
which has a funnel-shaped top or end to receive the valve or plug E on
or attached to the screw F, F, this pipe or tube being screwed or other-
wise attached to the lubricator cup at its lower end; E, the valve or
plug attached to the screw F, F, by means of which the aperture for the
flow of the lubricating material is regulated; F, F, the screw by means
of which the position of the valve or plug E is regulated; G, G, screw
joint by means of which the lubricator or cup A, A, is removed in order
to allow of the piston being placed in its proper position before filling
the lubricator; H and I, I, the steam-tight packing of the piston;
a, a, the hollow stem, shank, or support; b, b, the cock or plug through
which pass the passages c, c, and ƒ, ƒ,ƒ, ƒ, two or more in number for the
passage of the steam and lubricating material, and by means of which
their flow is regulated; c, c, the passage for the lubricating material;
d, d, the perforated bottom of the lubricator or cup through which
perforations the steam on entering through the passages f, F, F, I,
passes to act on the piston B, B; e, the steam-tight packing of the
screw F, F; f, f, f, f, steam passages to admit steam to act on the
piston.
To charge and set the lubricator (Fig. 1) to work it is necessary to
proceed as follows:-The cock or valve c on the pipe D being closed,
unscrew the top or cover C and lift it off; take hold of the stem 6 of
the piston B and draw it out of the lubricator or cup A, A; fill up
the cup with the lubricating material nearly to the entrance or opening
of the pipe D; place the piston B in the lubricator or cup A, A; put on
the top or cover C, having passed it over the stem 6 of the piston B, and
screw it on tight. Open the cock or valve d as much as necessary to
let the lubricating material flow out, and on opening the cock or
valve c on the pipe D'the steam will enter the lubricator or cup A, A,
liquify the lubricating material, and pressing on the piston B, force
it down to the bottom, propelling the liquified material before it through
the tube or passage f in the hollow stem, shank, or support a, a.

page_text: To charge and set the modification (Fig. 2) to work it is necessary
to proceed as follows:-Turn the cock or valve b, b, so as to close the
passages c, c, f, f,f, f; unscrew the cup or body of the lubricator at the
joint G, G, and press down or place the piston B, B, at its lowest point;
replace the cup or lubricator body A, A, and screw it on tight; unscrew 5
the cap or cover C, C, and fill up the cup or lubricator with the material
used level with the top; replace the cover C, C, and screw it on tight;.
adjust the valve or plug E by moving the screw F, F, to the amount of
opening required; open the cock or valve b, b, and the steam will pass
up by the passages f, f, f, f, through the perforations in the bottom d, d, 1
liquifying the lubricating material and pressing on the under side of
the piston B, B, will cause it to ascend and force the liquified lubricating
material past the valve or plug E down the pipe or tube D, D, and
through the passage c, c. The area of the passage c, c, being smaller.
than that of fƒƒƒ, prevents the steam pressure through c, c, from 1
being stronger than through ƒ,ƒ, f, f, whilst it does prevent the steam
from coming into actual contact with the lubricating lubricating material
which it helps to melt by its heat. This lubricator can be used in a
vertical, horizontal, or inclined position as may be desired.
Having now described my said Invention, and the manner in which 2
the same is to be performed, I would remark in conclusion that I do not
limit myself to the precise details expressed, as the same may be varied
or modified without in any way departing from the principle of my
Invention, but what I claim as my Invention is,--
First. A lubricator containing a piston or moveable partition, and 2
connected with a steam supply pipe through which steam can be
brought to bear upon the said piston or moveable partition, as herein-
before described.
Secondly. A lubricator provided with a sliding piston or moveable
partition and with steam passages for admitting the steam under the 3
piston or moveable partition, as herein-before described.
Thirdly. The pipe D and passage c, c, as shewn in Fig. 2, to operate in
conjunction with the piston B and steam passages f, f, f, f, as herein-
before described.
Fourthly. The cock b, b, as shewn in Fig. 2, arranged in the perforated 3
shank of the lubricator, for the purpose of regulating the passages c, c,
and ƒ, ƒ, ƒ, f, through the same, and the arrangement of the valve E on

page_text: the pipe D for regulating the lubricating material when forced by the
upward pressure of the steam on the sliding piston or moveable
partition B.
.
In witness whereof, I, the said Charles Frederic Trelawny Young,
have hereunto set my hand and scal, this Fourteenth day of
January, in the year of our Lord One thousand eight hundred
and seventy-one.
