Year: 1872

page_text: LETTERS PATENT to William Edward Teale, of No. 11, Mark Lane,
in the City of Manchester, in the County of Lancaster, Lamp
Manufacturer, for the Invention of "IMPROVEMENTS IN GUARDS FOR Gas
LIGHTS, AND IN AN IMPROVED METHOD OF LIGHTING GAS WHILE UNDER THE
PROTECTION OF GUARDS." o
Sealed the 27th May 1873, and dated the 4th December 1872.
PROVISIONAL SPECIFICATION left by the said William Edward Teale
at the Office of the Commissioners of Patents, with his Petition,
on the 4th December 1872.
I, WILLIAM EDWARD TEALE, of No. 11, Mark Lane, in the City of
Manchester, in the County of Lancaster, Lamp Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN GUARDS
FOR GAS LIGHTS, AND IN AN IMPROVED METHOD OF LIGHTING GAS WHILE UNDER THE
PROTECTION OF GUARDS," to be as follows:-

page_text: Firstly. In the application and use of protecting guards arranged so
as to prevent any tampering with the gas flame, and to prevent any
inflamable matter coming in contact therewith.
Secondly. In a new and improved method of lighting the gas without
removing the protecting guard.
In carrying out my Invention,-
Firstly. I fix permanently around the gas burner a frame made of
brass or other suitable metal, the top and bottom of which is closed in
with gauze, and glass; into the sides of said frame I place bent glass
plates, such plates being moveable upward or downward in a slide.
Secondly. I fix to the side or other convenient part of the brass frame
by means of a moveable joint a pencil tube, into which I place a fuse or
match so constructed that it may slide backwards and forwards through
the pencil tube that the end of the fuse or match may be brought into
contact with a serrated metal or other prepared surface which by friction:
will ignite the fuse or match from which the gas may be lighted.
SPECIFICATION In pursuance of the conditions of the Letters Patent,
filed by the said William Edward Teale in the Great Seal Patent
Office on the 4th June 1873.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I; WILLIAM
EDWARD TEALE, of
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of December, in the year
of our Lord One thousand eight hundred and seventy-two, and in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Teale, Her special
license that I, the said William Edward Teale, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward Teale,
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

page_text: more in detail the manner in which the same is or may be carried into
practical effect, and in order that my Invention may be the better
understood I annex hereunto a Sheet of Drawings illustrative thereof,
that is to say :-
A
On the accompanying Sheet of Drawings Fig. 1 represents a side
view of my improved guard for gas lights; Fig. 2, a section of the
same; and Fig. 3 a plan. a, a, a, a, is a light frame of brass or other
suitable metal; b, b, b, curved or bent glass plates moveable upwards or
downwards in a slide or groove in the framework (see Fig. 3); c, a
common gas burner screwed into a gas pipe d which is secured to the
framework by means of an ordinary screw nut; e, e, is a hollow pencil
tube working freely on a ball and socket joint at f, f, (see Fig. 2);
9, 9, is a prepared match or fuse which slides freely within the hollow
tube e, e; h, is a metal spring serrated at its upper end and secured to
the framework by a screw (see Fig. 1); i, i, is a metal rod for the
purpose of supporting the guard in any required position, and is screwed
into the framework at one end; the other end is formed into a bow
which opens on a joint at ; ; is a thumb screw for tightening the bow
upon any support that may be used for fixing the guard upon; 1, 1, is a
wire guaze cap or cover enclosing the top of the guard; k is a metal
rod which passes through the upper part of the framework and through
the wire guaze cap or cover, being firmly secured at each end by a screw
nut which projects over the upper edges of the bent glass plates,
thus preventing the removal of either the glass plates or wire guaze
cover.
D
In order to light the gas while under the protection of guards, as now
described, I place in the hollow tube e, e, a prepared fuse or match, the
same extending a short distance beyond the point of the tube, as
represented in Figs. 1 and 2, and by a slight movement of the tube
upon its ball joint the end of the fuse or match is brought in contact
with the serrated surface of the spring h, and by the friction of the
upward movement of the fuse or match the same becomes ignited and
lights the gas issuing from the burner c, as shown in Fig. 1. I may use
instead of the serrated surface of the spring a chemically prepared
surface to ignite the fuse or match.
Having now described the nature and object of my said Invention for
improvements in guards for gas lights, and in an improved method of
lighting gas while under the protection of guards, together with the

page_text: -
manner in which the same is or may be carried into practical effect, I
will remark in conclusion that I claim as new and of
my Invention,
Firstly. The general arrangement and construction of guards for gas
lights, as herein-before described and illustrated.
Secondly. The combination and arrangement of apparatus for lighting
gas while under the protection of guards, in the manner and for the
purpose herein-before described and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, I, the said William Edward Teale, have here-
unto set my hand and seal, this Third day of June, in the year of
our Lord One thousand eight hundred and seventy-three.
WILLIAM EDWARD TEALE. (L.S.)
