Year: 1866

page_text: LETTERS PATENT to William George Beattie, of South Bank, Surbiton,
in the County of Surrey, Engineer, for the Invention of "AN IMPROVED
APPARATUS FOR LUBRICATING PURPOSES."
Sealed the 3rd July 1866, and dated the 6th January 1866.
PROVISIONAL SPECIFICATION left by the said William George Beattie
at the Office of the Commissioners of Patents, with his Petition, on the
6th January 1866.
I, WILLIAM GEORGE BEATTIE, of South Bank, Surbiton, in the County of
Surrey, Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED APPARATUS FOR LUBRICATING PURPOSES," to be as follows:-
I have a hollow metallic vessel of cylindrical or other convenient form and
size to contain the oil or other lubricating liquid, and at the lower part or
bottom thereof I have a regulating cock, with a hollow passage in the plug
of it for one-quarter of its circunference, connected with two hollow passages
formed in the metal of the vessel, one passage leading to the interior of the
vessel and the other leading to a suitably shaped aperture on the exterior
of the top of the vessel to regulate the admission of the liquid to the vessel.
I have also a small hollow passage in the plug of the cock connected at one

page_text: end with a passage formed in the metal of the vessel leading to the top of
the interior, and at the other end opening to the air through the end of the
plug; by these means I provide an outlet for the air or vapour, and enable
the lubricating liquid to flow easily into the interior of the vessel. I also
have several small passages through the plug of the cock at a short distance
from each other and extending over less than one-quarter of the circumference
of the plug; they are connected at both sides of the plug with a square
passage less in width than one-quarter of the circumference of the plug
leading from the interior of the vessel, and forming the outlet for the liquid,
and by these means I regulate the supply of oil issuing from the vessel.
These several passages for the admission of the liquid, for the outlet for
air, and for regulating the flow of liquid for the lubrication are formed in the
plug of the cock in such positions that when the cock is open for admission
of the liquid it is also open for the outlet of air and shut for the outlet of
liquid, and that when the cock is open for outlet of liquid it is shut for
admission of liquid or outlet of air. I insert in the metal of the side of the
vessel a glass guage tube which communicates at both ends with the interior
of the vessel, and I secure it in its position by cementing it externally to the
metal for a short distance of its length at both ends, and opposite the
remainder of its length I have a vertical open slot, and as the oil will thus
always be at the same height in the tube as it is in the vessel the quantity
therein will be indicated in the tube. The outlet under the cock is screwed
externally so that the lubricator can easily be attached to the machinery to be
lubricated, and my lubricator as described will work either with or without
the admission of steam.
In another modification of my lubricator I have an inlet cock for the liquid
of the cup-shaped aperture at the top, making it of a conical form, as a plug
at the lower part, and inserting it in a seating at the top of the lubricator.
There are also passages communicating with the interior of the cup and the
interior of the lubricator, and by altering the position of the cup these
passages can be either shut or opened for the admission of the liquid, one
opening being contrived to let away the air from the interior of the vessel,
and the liquid enters by the other openings, and I have below the cylindrical
vessel either a cock with small perforations as before described, or a screw
valve, by which means the quantity of liquid passing out can be regulated.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GEORGE BEATTIE, of South Bank, Surbiton, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of January, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William George Beattie, Her special licence that I the said William George
Beattie, my executors, administrators, and assigns, or such others as I, the
said William George Beattie, 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
APPARATUS FOR LUBRICATING PURPOSES," upon the condition (amongst others)
that I, the said William George Beattie, my executors or administrators, 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 William George Beattie, 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 the Sheet of Drawings which forms part of this
my Specification, and the figures and letters marked thereon.
I have a hollow metallic vessel of cylindrical or other convenient form and
size to contain the oil or other lubricating liquid, and at the lower part or
bottom thereof I have a regulating cock, with a hollow passage in the plug
of it for one-quarter of its circumference, connected with two hollow passages
formed in the metal of the vessel, one passage leading to the interior of the
vessel and the other leading to a suitably shaped aperture on the exterior of
the top of the vessel to regulate the admission of the liquid to the vessel; I

page_text: have also a small hollow passage in the plug of the cock connected at one
end with a passage formed in the metal of the vessel leading to the top of
the interior, and at the other end opening to the air through the end of the
plug; by these means I provide an outlet for the air or vapour, and enable
I also
the lubricating liquid to flow easily into the interior of the vessel.
have several small passages through the plug of the cock at a short distance
from each other, and extending over less than one-quarter of the circumference
of the plug; they are connected at both sides of the plug with a square
passage less in width than one-quarter of the circumference of the plug
leading from the interior of the vessel, and forming the outlet for the liquid,
and by these means I regulate the supply of oil issuing from the vessel.
These several passages for the admission of the liquid, for the outlet for air,
and for regulating the flow of liquid for the lubrication, are formed in the
plug of the cock in such positions that when the cock is open for admission
of the liquid it is also open for the outlet of air and shut for outlet of
liquid, and that when the cock is open for outlet of liquid it is shut for
admission of liquid or outlet of air. I insert in the metal of the side of the
vessel a glass guage tube which communicates at both ends with the interior
of the vessel, and I secure it in its position by cementing it externally to the
metal for a short distance of its length at both ends, and opposite the
remainder of its length I have a vertical open slot, and as the oil will thus
always be at the same height in the tube as it is in the vessel the quantity
therein will be indicated in the tube. The outlet under the cock is screwed
externally so that the lubricator can easily be attached to the machinery to
be lubricated, and my lubricator as described will work either with or without
the admission of steam.
In another modification of my lubricator I form an inlet cock for the liquid
by the cup-shaped aperture at the top, making it of a conical form as a plug
at the lower part, and inserting it in a seating at the top of the lubricator.
There are also passages communicating with the interior of the cup and the
interior of the lubricator, and by altering the position of the cup these passages
can be either shut or opened for the aduiission of the liquid. One opening
being contrived to let away the air from the interior of the vessel, and the
liquid enters by the other openings, and I have below the cylindrical vessel,
either a cock with small perforations as before described or a screw valve, by
which means the quantity of liquid passing out can be regulated. I have also
as before described a glass guage to indicate the quantity of liquid in the
lubricator.

page_text: In order that the foregoing description of my apparatus may be better under-
stood, I refer to the Sheet of Drawings forming part of this my Specification,
and also to the following description :--
Figure 1 (Sheet No. 1) shews a vertical section of lubricator; Figure 2 is
an outside elevation thereof; Figure 6 is a sectional plan.
The construction is as follows:-The passage A, A, is formed in the metal
of the cylindrical body, and leads from the cup B to the conical plug C, by
which it communicates with ascending passage D, D (Figure 6), having its
opening E at the top of the interior of the cylindrical body; by this means the
lubricator may be filled with lubricating liquid. The passage F, F, is also
formed opposite to the passage A, A, in a similar manner, and communicates
with the passage a, a in the conical plug C, so that the air may escape from
the lubricator when it is being filled. The interior of the vessel has a com-
munication at G with the conical plug C, and by means of the small holes
in the plug (shewn also at Figure 7) the escape of the lubricating liquid
may be regulated, the boles being so placed that when open for the escape of
lubricating liquid the passage A, A, is closed by the plug for the admission
of liquid, but the passage D, D, is open for admission of steam, as shewn at
Figure 8. The glass guage tube is placed in the metal of the side of the vessel
as shewn, and is secured in its place by ordinary suitable cement or expansive
composition compressed by the screw plugs H, H, which are hollow as shewn,
and have openings communicating with the top and bottom of the interior of
the vessel so that the lubricating liquid may always be at a height in the glass
tube corresponding with its height in the vessel, and be visible from the out-
side of the lubricator as in Figure 2. The cup B is provided with a loose
cap attached to it by a small chain. The plug C has a handle and pointer,
Figures 1 and 2; Figures 3, 4, and 9 shew a lubricator of a construction similar
to that shewn in Figures 1, 2, and 6, but the passages A, A, D, D, F, F,
are differently placed and are formed separately from the body of the vessel,
which is in two parts and is screwed together at I, I. The letters indicate the
same parts in Figures 3, 4, and 9 as in Figures 1, 2, and 6.
Figure 5 shews another modification. The inlet cock for the admission of
lubricating material being attached to the hollow cup J, and the liquid passes
through the hollow plug K by the passage L to the interior of the vessel, at
the same time the air escapes from the interior by the passage at M.. The
passages L and M are placed opposite, so that if one is open to admit liquid
the other is also open to allow air to pass out, or if one is shut the other is
also shut. The flow of liquid from the lubricator is regulated by the screw

page_text: cock at N. The plug O has a quick thread formed on it, and passes through
the small stuffing box at P. The screw plug has its seating at Q, and when
open the steam ascends by the tube R, and the liquid escapes at S. The glass
guage can be used as in Figure 1, or a very small guage cock may be inserted
in the bottom of the cylinder body.
Having described the nature of my said Invention, and in what manner the
same is or may be performed, I wish it to be understood that I do not claim
any of the parts separately, but that what I claim as my Invention is, the
combination and arrangement of parts as herein-before mentioned and described
and shewn in Sheet I. Figures 1, 2, 3, 4, 5, 6, 7, 8 and 9.
In witness whereof, I, the said William George Beattie, have hereunto
set my hand and seal, this Sixth day of July, in the year of our Lord
One thousand eight hundred and sixty-six.
WILLIAM GEORGE BEATTIE. (L.S.)
