PROVISIONAL SPECIFICATION left by the said George. Bray at the
Office of the. Commissioners of Patents, with his Petition, on the.
6th August 1872.
I, GEORGE BRAY, of Leeds, in the. County of York, Enamel Gas
Burner Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN-GAS BURNERS," to be as follows:-
This Invention relates to a certain kind of gas burner composed or
constructed of a socket or tube of brass or other ductile metal, having a
fishtail or union jet tip inserted therein. This class of tip is known in
the trade as “enamel," "adamas," "lava," "stealite," &c., and,may be
described by tho general terms, earthenware- or non-corrosive tip, and
are made wholly-or in part by moulding, and while the material is in a
more or less plastic state. The tip used hitherto, or that part of it round
which the socket fits, is more or less taper, having-its-largest diameter.at
the top or outer part, and tapering downwards and inwards, and is secured
in the socket by being diven or pressed into it, and sometimes by the,

page_text: socket being pressed or closed to the side of the tip. Also in this class
of burner is often inserted in the socket or tube a regulator or modifier
of the flow of gas, composed of a membrane of muslin or other woven
fabric.
Now, in practice I have found that by the unequal expansion and
contraction (when in use) of the different materials of which the sockets
and tips are made, and from the straining of the sockets when the burner
is being fixed for use, the tips are liable to and frequently do come out
of the sockets. To remedy this I reverse the usual shape of that part of
the tip round which the socket fits, making it smaller in diameter at
the top or outer part, and enlarging in diameter down to the bottom
thereof, or a sufficient distance down, so that when the tip is inserted in
the socket the end of the said socket may be compressed or turned over
the larger and on to the smaller diameter of the tip sufficiently to hold
the said tip without getting above it. Round its largest diameter I also
form a slight ridge, and when the socket is closed over the said ridge
that is an additional safeguard against the tip getting out.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Bray in the Great Seal Patent Office on
the 6th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BRAY, of Leeds, in the County of York, "Enamel" Gas Burner Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of August, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Bray, Her special licence that
I, the said George Bray, my executors, administrators, and assigns,
or such others as I, the said George Bray, my executors, adminis-
trators, 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,

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN GAS BURNERS,” upon
the condition (amongst others) that I, the said George Bray, my exc-
cutors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascer-
tain 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.
n
NOW KNOW YE, that I, the said George Bray, 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, that is to
say:
⋅
This Invention relates to a certain kind of gas burner composed or
constructed of a socket or tube of brass or other ductile metal, having a
fishtail or union jet tip inserted therein. This class of tip is known in
the trade as “ enamel," "adamas," "lava," stealite, &c., and
be
may
described by the general terms, earthenware or non-corrosive tip, and
are made wholly or in part by moulding, and while the material is in a
more or less plastic state. The tip used hitherto, or that part of it round
which the socket fits, is more or less taper, having its largest diameter at
the top or outer part, and tapering downwards and inwards, and is
secured in the socket by being driven or pressed into it, and sometimes
by the socket being pressed or closed to the side of the tip. Also in this
class of burner is often inserted in the socket or tube a regulator or
modifyer of the flow of gas, composed of a membrane of muslin or other
woven fabric.
Now, in practice, I have found that by the unequal expansion and
contraction (when in use) of the different materials of which the sockets
and tips are made, and from the straining of the sockets when the burner
is being fixed for use the tips.are liable fo and frequently do come out
of the sockets. To remedy this I reverse the usual shape of that part
of the tip round which the socket fits, making it smaller in diameter at
the top or outer part, and enlarging in diameter down to the bottom
thereof, or a sufficient distance down, so that when the tip is inserted in
the socket tlic end of the said socket may be compressed, or turned over
the larger and on to the smaller diameter of the tip sufficiently to hold

page_text: the said tip without getting above it. Round its largest diameter I also
form a slight ridge, and when the socket is closed over the said ridge
that is an additional safeguard against the tip getting out.
In order that the Invention may be clearly understood I have here-
unto annexed a Sheet of Drawings showing the various parts of a gas.
burner, drawn to an enlarged scale, constructed according to this my
Invention, and have marked the parts with letters corresponding to those
in the following description.
A is the "tip," and that portion thereof round which the end of the
socket B fits is, as shown, tapered towards the top, and so that when the
said tip is inserted within the socket B, and the end of the latter is com-
pressed or turned over the tip, by reason of its largest diameter being
below and within the socket end so turned over as described, is thus
secured in its place, and the ridge E on the tip is an additional guard
against the tip getting out of place.
'
Having thus fully described the nature and particulars of this my said
Invention, together with the manner in which the same is to be, or may
be performed or carried into practical effect, I would have it distinctly
understood that what I claim as my Invention is, the construction and
use of gas burners having the tips tapered in the manner and for the
purpose herein fully described, whether such tips are provided with the
ridge E or not.
In witness whereof, I, the said George Bray, have hereunto set
my hand and seal, this Third day of February, in the year of
our Lord One thousand eight hundred and seventy-three.
