Year: 1865

page_text: LETTERS PATENT to Isaac Beamis" of No. 3, Leadenhall Street, in the
City of London, Engineer, for the Invention of "IMPROVEMENTS IN
LUBRICATING APPARATUS."
Sealed the 13th March 1866, and dated the 14th September 1865.
PROVISIONAL SPECIFICATION left by the said Isaac Beamish at the
Office of the Commissioners of Patents, with his Petition, on the 14th
September 1865.
I, ISAAC BEAMISH, of No. 3, Leadenhall Street, in the City of London,
Engineer, do hereby declare. the nature of the said Invention for "IMPROVE-
MENTS IN LUBRICATING APPARATUS," to be as follows, that is to say :-
My Invention consists in the construction and arrangement of a new
description of lubricating apparatus which is represented in the Drawings
accompanying this Provisional Specification.
Figure 1 is a section at A, B, (Figure 3); Figure 2 is a side elevation;
and Figure 3 is a section at C, D, (Figure 1).
The action of the apparatus is as follows:-The glass cylinder a, a, a, a, is.
filled with water up to the top of the small tube b, the cock c being closed..
The cylinder a, a, a, a, is then filled with oil through the cock d. The pipe e.
is in connection with the steam pipe, and the pipe f in connection, with the
valve box. The steam coming from the steam pipe passes through.e, thence.

page_text: through the pipe g, g, and enters the cylinder at h, and partly condenses and
also creates a pressure in the cylinder a, a, a, a. The oil being at the top of
the water will be forced into the pipe i, leading to the valve box. A screwed
spindle with conical point and hand wheel are for the purpose of
regulating the supply of oil. As the water accumulates from the condensation
of the steam, and as the oil decreases in quantity by being forced through
at i, the latter being at the top of the water will ensure a supply until all
the oil is used.
The apparatus is made self-acting by means of two valves, one m, attached
to the pipe e, and one n, attached to the pipe f. Valve m is to prevent the
escape of any oil into the pipe e, for in case the pressure in the pipe & should
be less than in the glass cylinder the valve m will close. The valve n is for
the purpose of preventing steam pressure in the cylinder when the action of
the apparatus for a time ceases. The pipe is provided with a cock for the
purpose of regulating the supply of steam, and the pipe f with a cock to stop
the action of the apparatus. The screws 0, 0, 0, are to connect the upper
and lower cylinder ends.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Isaac Beamish in the Great Seal Patent Office on the
14th March 1866.
TO ALL TO. WHOM THESE PRESENTS SHALL COME, I, ISAAC
BEAMISH, of No. 8, Leadenhall Street, in the City of London, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Isaac Beamish, Her special licence that I, the said . Isaac
Beamish, my executors, administrators, and assigns, or such others as I, the said
Isaac Beamish, 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
LUBRICATING APPARATUS," upon the condition (amongst others) that 1, the
said Isaac Beamish, my executors or administrators, by an instrument

page_text: 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 Isaac Beamish, 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, that is to say :-
My Invention relates to the construction and arrangement of a new
description of lubricating apparatus, more especially designed to supply the
requisite quantity only, so as to avoid waste of lubricating material to those
parts of steam or heated air engines acted upon the vapour or heated air,
more particularly to the valves and cylinders. By the use of this apparatus
the lubricating material will be thoroughly intermixed with the steam or
heated air as it enters the valve box and equally distributed over the working
surfaces. When superheated steam or heated air is employed this lubricating
apparatus will be found highly advantageous, inasmuch as by its use the
destruction of the valve faces and piton packings by the dryness of the eam
or heated air will be entirely prevented, the steam or heated air carryin th
it particles of lubricating material. The steam may, in fact, be superhé (ted,
when this apparatus is used, to a greater degree than heretofore, and a much
greater economy in fuel will result.
:
In order that the nature of my Invention, and the means by which I effect
the same may, be clearly described and ascertained, I to this Specification
append a Sheet of Drawings, having figures and letters of reference marked
thereupon, the like letters being used to denote similar parts in each
Figure.
In these Drawings Figure 1 is a section at A, B, of Figure 3; Figure 2
is a side elevation; and Figure 3, a section at C, D, of Figure 1.
The apparatus consists of a glass cylinder a, a, a, a, for the purpose of
containing the lubricating material, which cylinder has a top piece of brass or
other metal, and also a bottom piece of brass or other metal. These two
pieces are each made with a circular groove, the top piece on its under side
and the bottom piece ou its upper side, and these two pieces and the glass
cylinder are held together by the screwed bolts and nuts 0, 0, 0.
Into the
circular grooves before mentioned the glass cylinder is entered and is carefully
packed therein, so as to be steam and water tight, by means of rings of vulcanized
india-rubber or other material, or other packing of any description may. be

page_text: .
used which will make a tight joint. The other parts of this apparatus will
be found sufficiently described so that their construction and the purposes
which they severally and jointly serve may be clearly understood by reference
to the herein-before mentioned Drawings, and the following description of the
action of the apparatus:-
Into the glass cylinder a, a, a, a, water is poured until it reaches the level of
the top of the small tube b, the cock c, being at the same time closed. The
cylinder a, a, a, a, is then filled with oil through the cock d. The pipe e is in
connection with the steam pipe, and the pipe f enters into the steam pipe at or
near to the valve box or into the valve box. The steam coming from the
steam pipe passes through e, thence through the pipe 9, 9, and enters the
lubricator cylinder at h, and partly condenses, and also creates a pressure in
the cylinder a, a, a, a. The oil being at the top of the water will be forced
into the pipe i, leading towards the valve box. A screwed spindle k, provided
with a conical point and also with a hand wheel l, is for the purpose of
regulating the supply of oil. As the water accumulates from the condensation
of the steam, and as the oil decreases in quantity through being forced through
att, the latter being at the top of the water, a constant supply will be ensured
'until all the oil is used.
The apparatus is made self-acting by means of two valves, one m, attached
'to the pipe e, and one n, attached to the pipe f. Valve m is to prevent the
escape of any oil into the pipe e, for in case the pressure in the pipe e should
be less than in the glass cylinder the valve m will close. The valve n is for the.
purpose of preventing steam pressure in the glass cylinder when the action of
the apparatus for a time ceases. The pipe e is provided with a cock p for
the purpose of regulating the supply of steam, and the pipef with a cock q
'to stop the action of the apparatus.'
Although I have heretofore in this Specification described this lubricating
apparatus as having a glass cylinder, it will be obvious that such a cylinder is
used for the purpose of enabling the engineer in charge to see at any time at
'a glance the state of his lubricator. I may, however, attain the same end by
using a metal cylindrical or other shaped case having openings therein, in which
'are placed pieces of glass, tale, or other transparent material securely fitted
so as to be perfectly steam and water tight, or when it is not deemed of
importance to see the interior of the lubricator from without I may use a
metal cylinder without openings, connected by the top and bottom pieces as
berein-before described, or I may cast or make the top, bottom, and substitute
'for the glass cylinder in one piece, and use the same with the arrangement of
tubes, cocks, and regulator, as herein-before described.

page_text: Having now particularly described and ascertained the nature of my
Invention, and the manner in which the same is to be performed, I wish
it to be understood that what I claim as of my Invention is, the general con-
struction and general arrangement of parts as in this Specification and appended
Drawings described and illustrated, and the particular construction and
combination or arrangement of the tubes e, 9, 9, with valve m, and cock p,
and of the tubes f, f, i, with valve n, and cock q, and the combining together
of these two arrangements of parts in lubricating apparatus.
In witness whereof, I, the said Isaac Beamish, have hereunto set my
hand and seal, this Twenty-fifth day of November, in the year of our
Lord One thousand eight hundred and sixty-five.
ISAAC BEAMISH.
