-
Lake, & Co., Patent Agents, Southampton Buildings, London,
for the Invention of "IMPROVEMENTS IN GAS BURNERS. A
communication from abroad by Toussaint Trudeau, of Ottawa,
Canada.
Sealed the 23rd December 1875, and dated the 11th August 1875.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 11th August 1875.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN GAS BURNERS," a
communication, to be as follows:-
The objects of my Invention are, first, to provide a burner which will
economically consume gas without noise, and whose parts regulating
the supply can be easily placed in position, and easily exchanged without

page_text: disturbing the adjustment of the pillar or the gallery supporting the
shade; further, to make the pillar or burner holder adjustable, so that
the gallery and shade can be adjusted horizontally, and permanently
secured in that position.
In gas pendants carelessly made it not unfrequently happens that the
pipe holding the burner leans to one side, and that the gallery sup-
porting the shade being rigid on the burner the shade also falls to one
side. My Invention furnishes a simple remedy for this defect.
The said Invention comprises a gas pillar fitted with a ball-and-socket
joint for the horizontal adjustment of the gallery and shade; also a 1
tube forming a double regulated gas burner not supporting the gallery,
and capable of being inserted into and removed from the pillar without
disturbance of the other portions of the burner or the gallery. It also
comprises a combination of parts to form a gas pillar, having a ball-and-
socket joint for the horizontal adjustment of the gallery and shade, and 1
to form a ball-and-socket gas burner adjustable horizontally, and having
a double regulated tip or burner, which may be exchanged or adjusted
without disturbing the pillar or gallery.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 9th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of August, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Robert Lake, Her
special licence that I, the said William Robert Lake, my executors,
administrators, and assigns, or such others as I, the said William
Robert Lake, 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

page_text: make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN GAS BURNERS," a communication to me from
abroad by Toussaint Trudeau, of Ottawa, Canada, upon the condition
(amongst others) that I, the said William Robert Lake, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, 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 Robert Lake, 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, reference being had to the accom-
panying Drawing forming a part of this Specification :-
The objects of my Invention are, first, to provide a burner which will
economically consume gas without noise, and whose parts regulating
the supply can be easily placed in position and easily exchanged without
disturbing the adjustment of the pillar or the gallery supporting the
shade; further, to make the pillar or burner holder adjustable, so that
the gallery and shade can be adjusted horizontally, and permanently
secured in that position.
In gas pendants carelessly made it not unfrequently happens that the
pipe holding the burner leans to one side, and that the gallery sup-
porting the shade being rigid on the burner the shade also falls to one
side. My Invention furnishes a simple remedy for this defect.
The said Invention is illustrated in the accompanying Drawing, in
which,―
Figure 1 is a vertical section of an ordinary gas pillar and tip.
Figure 2 is a vertical section of one of my improved burners ready for
use, without the ball-and-socket adjustment. A is a pillar; B is a
conical tube with lower regulated opening; C is a tip.
Figure 3 is a vertical section of the said conical tube B, without the
said pillar or tip. The tube is of thin metal open at the top with a
regulated opening below formed of a slit or one or more perforations ;

page_text: the slit is preferable. This conical tube may be smooth, and inserted in
the pillar as a plug, or it may have a thread and be screwed into the
pillar. For high pressure a wire gauze disc p, p, may be fitted above
the lower orifice, with the addition of a small quantity of wool.
Figure 4 shows the tube B with a regulated opening below; it is
fitted to the inside of the tip.
Figures 5, 6, and 7 are sections of my ball-and-socket gas pillar sup.
porting gallery and shade. D is the ball; E, F, the two pieces of pillar
forming the socket; G, G, the gallery; H, leather washer between ball
and shell of pillar to render the ball and socket joint gas-tight In
Figure 5 the tube B is inserted in the pillar; in Figure 6 the regulated
opening I is through the cap of the ball; and in Figure 7 the pressure
of the gas is regulated by a small tap t, t.
Figure 8 is another form of ball-and-socket pillar, in which D is the
ball; E, F, are the two pieces forming the socket; and H is the
leather washer.
In fitting the pillars, Figures 5, 6, 7, and 8, they are so adjusted that
the gallery is horizontal; the pieces E, F, forming the socket are screwed
together so as to press firmly on ball D. The joint between the ball-
and-socket may be filled with white lead, thus any tendency to movement
after adjustment is obviated.
Figures 9, 10, and 11 are modified forms of ball-and-socket pillars.
In each K represents the base of the pillar; L is an adjustable centre,
which in this case is the centre piece or hub of gallery. In Figure 9
M is the tube, with or without regulated lower opening, which screws
into base K; in Figures 10 and 11 the gallery is secured by nut N.
It will be evident that the ball-and-socket pillar may be fitted with any
appliance designed to reduce the pressure of gas. For general use I
prefer the form of pillar shewn in Figure 5.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I do not claim the introduction of two
separate orifices one above the other, or the use of a tap for the purpose of
reducing the pressure of gas, neither do I claim the introduction of the
wire gauze, disc, and wool, but I claim,-
First. A gas pillar fitted with a ball-and-socket joint for the horizontal
adjustment of the gallery and shade, as above set forth.

page_text: Second. A. tube forming a double regulated gas burner not supporting
the gallery, and capable of being inserted into and removed from the
pillar without disturbance of the other portions of the burner or the
gallery, as above set forth.
Third. The combination of the parts D, E, F, or K, L, M, or K, L, N,
to form a gas pillar, having a ball-and-socket joint for the horizontal
adjustment of the gallery and shade, as above set forth.
Fourth. The combination of the parts D, E, F, or K, L, N, with the
tube B to form a ball-and-socket gas burner adjustable horizontally, and
having a double regulated tip or burner, which may be exchanged or
adjusted without disturbing the pillar or gallery, as above set forth.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Ninth day of February, in
the year of our Lord One thousand eight hundred and seventy-
six.
