Year: 1872

page_text: LETTERS PATENT to Charles Robert Mathews, of 52, High Street,
Bloomsbury, in the County of Middlesex, Gas Engineor and Gas
Lantern and Lamp Manufacturer, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR SAFE, SPEEDY, AND EASY MODE IN FIXING, CON-
NECTING, AND DISCONNECTING GAS PENDANT, BRACKET, PILLAR, OR GROUND
PROVISIONAL SPECIFICATION left by the said Charles Robert
Mathews at the Office of the Commissioners of Patents, with his
Petition, on the 26th March 1872.
I, CHARLES ROBERT MATHEWS, of 52, High Street, Bloomsbury, in
the County of Middlesex, Gas Engineer and Gas Lantern and Lamp
Manufacturer, do hereby declare the nature of the said Invention for
" IMPROVEMENTS IN APPARATUS FOR SAFE, SPEEDY, AND EASY MODE IN FIXING,
CONNECTING, AND DISCONNECTING GAS PENDANT, BRACKET, PILLAR, OR GROUND
CONNECTIONS, ESPECIALLY ADAPTED FOR OUTSIDE REFLECTING LAMPS," to be as
follows:-
६
1st.. I insert a cast metal plate level with the facia wall or floor
having two or more slots with a square or circular hole containing indian-

page_text: rubber disc or washer through which the gas is directed below the slot
fastenings.
2nd. The object is to obtain a very strong, steady, and secure
fixing without the use of screws, fly nuts, or loose fastenings, the
washer or disc receiving a regulated pressure, whereby the joint is
made sound.
3rd. I further lock or secure the connection in the plate by a simple
motion attached to same, which is similar to an ordinary turn, and
securely prevents the hinge joint opening.
4th. The connections attached to reflecting lamps is similar motion to 1
the above joint, with the addition of an invisible tap or slido valve of
great durability and strength combined with artistic appearance.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Robert Mathews in the Great Seal Patent
Office on the 26th September 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ROBERT MATHEWS, of 52, High Street, Bloomsbury, in the County of
Middlesex, Gas Engineer and Gas Lantern and Lamp Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of March, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Charles Robert Mathews, Her special
licence that I, the said Charles Robert Mathews, my executors, admi-
nistrators, and assigns, or such others as I, the said Charles Robert
Mathews, 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 "Iм-
PROVEMENTS IN APPARATUS FOR SAFE, SPEEDY, AND EASY MODE IN FIXING,
CONNECTING, AND DISCONNECTING GAS PENDANT, BRACKET, PILLAR, OR GROUND
CONNECTIONS, ESPECIALLY ADOPTED FOR OUTSIDE REFLECTING LAMPS," upon the

page_text: condition (amongst others) that I, the said Charles Robert Mathews,
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 Charles Robert Mathews, 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:-
This Invention consists in a new arrangement of gas connections
more especially adopted for outside reflecting lamps by which a greater
simplicity and security is combined with a more artistic appearance,
also a great saving in gas.
By this arrangement the fixing and unfixing can be performed in an
instant without screws or any loose fastenings, and without the aid of
a ladder; the pendant irons not being so long, the leverage is conse-
quently greatly reduced, and allowing more headway for foot passengers.
The fixing can be made also at any angle on the ceiling, wall, or floor
with equal despatch and security. The bottom fitting attached to the
lamp itself being strongly soldered to jointed ribs at the back of
the lamp, thus preventing the buckling of the plated metal surface.
When the pendant is not required there is an arrangement by which
the facia plate can be covered, and is more particularly described
hereafter.
By this Invention all the component parts being made to a set
pattern and design and kept in stock they can be sent to any place, and
refixed by an ordinary workman in a few minutes at a nominal cost.
Where bull's-eyes are used the fittings being above the centre of the
lamp do not, obscure the light.
Now in order that this my Invention may be clearly and readily
understood reference is made in the following detailed description to
accompanying Drawings, the letters of references thereon referring to
like parts throughout.
Fig. 1 shews a section (see also Fig. 2) of the mode of fixing the
upper part of the pendant. to the facia (or wall).

page_text: a, a, is the facia; b, a sunk metal receiving plate level with the surface
of the facia having slots c, c, and a circular opening d; a washer of:
india-rubber e is inserted behind the orifice d having a corresponding
hole through it for the free passage of gas. To attach the curved pendant.
to this sunk plate all that is necessary is to insert the two studs or
buttons ff, (see also Fig. 3,) into the slots c, c, which drop down and
allow the mouth of the curved pendant g to come into communication
with the orifice d in the facia plate, against which it presses tightly by
reason of its own weight. The buttons above mentioned are attached to
a hinged piece h so that they may be inserted first, and the projecting
mouthpiece g falling readily into its orifice. To prevent its displacement
there is a moveable stop i with a drop handle which is turned round by
a stick with a cross cut in it, and comes immediately under the curved
back of the hinged piece h, and thoroughly securing it and preventing
its opening and escape of gas.
Figs. 4 and 5 shew the front and side views of the curved pendant
when fixed complete.
Fig. 6 is a sectional view of the lower portion of the pendant to which
the reflecting lamp is attached. k is the pipe to which is screwed the
portion termed the pendant block or bottom joint l, l, which contains a
slide valve m for supplying or stopping off gas to the lamp, the advantage
being its great durability, easy action, and non-liability to get out of
repair; it is moved up or down by the thumb knob n. The bottom of
the block is stopped by means of the screw nut o with washer attached,
allowing of any collection or deposit flowing from or collecting in the
pendant iron to be instantly cleared out. p is the gas way extending
as far as the india-rubber washer q, q, similar to that described in the
upper connections. Now to fix the claw portion attached to reflecting
lamp all that is necessary is to hook on the portion p on which the
hinges is formed, which is made perfectly secure by means of a lever t,
the curved claws u, u, being securely soldered to lamp back.
Figs. 7 and 8 are front and side views of the bottom block.
Fig. 9 is the hinged covering for the facia plate when the supply to
any one plate is not required, the arrangement being similar to the
attachment, Fig. 1, but is locked or fixed by the turn button and slot v, v,
(see also Fig. 2).
Having thus described the nature of this my said Invention, now
what I claim and desire to be secured to me by Letters Patent is, the

page_text: said Invention for improvements in apparatus for safe, speedy, and easy
mode in fixing, connecting, and disconnecting gas pendant, bracket,
pillar, or ground connections, especially adapted for outside reflecting
lamps, substantially as herein described and as shewn in accompanying
Drawings, or any mere modification thereof.
In witness whereof, I, the said Charles Robert Mathews, have
hereunto set my hand and seal, this Twenty-sixth day of
September, in the year of our Lord One thousand eight hundred
and seventy-two.
CHARLES RT. MATHEWS. (L.S.)
