PROVISIONAL
SPECIFICATION.
Improvements connected with Gas-heated Ovens and similar
Apparatus.
I, EDMOND WALter Tyrrell RICHMOND, of Academy Street, Warrington,
in the County of Lancaster, Managing Director, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to gas heated ovens, and other similar gas heated
apparatus in which the burners are of horizontal Bunsen or atmospheric type; and
its nature will be described as applied to an oven where horizontal atmospheric
burners are placed in the lower part or bottom of the oven, and within the walls of
the oven; it being understood that similar, or substantially similar, modes of
arrangement and carrying the burners may be applied in connection with other
apparatus heated by gas in an analogous or similar way.
According to this invention, the burners are loosely mounted; and in some cases
are arranged one on either side; and they are supported at one end, say the back
end, by fitting and resting in a socket, or in any other suitable support, while at the
other end, the front end, they are carried by the pipe which supplies the gas to
them, by suitable carriers or devices which slip over the said pipe, or by similar
provisions, upon the side of which nearest the burners, the burner ends rest, while
the other side (in the case of the pipe being round) is steadied or held by bearing
upon a part of the oven wall the gas-pipe itself passes through the side walls of
the oven.
:
The nipples which supply the gas from the pipe to the atmospheric burners,
direct the gas horizontally into a tube lying parallel with the burner tube in which
the burner nozzles or holes are provided; and it may be formed thereon at the
back of such tube, the entrance to the tube being constructed to admit the necessary
air for admixture with the gas.

Improvements connected with Gas-heated Ovens and similar
Apparatus.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington,
in the County of Lancaster, Managing Director, do hereby declare the nature of
this 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 has reference to gas heated ovens, and other similar gas heated
apparatus in which the burners are of horizontal Bunsen or atmospheric type; and
its nature will be described as applied to an oven where horizontal atmospheric
burners are placed in the lower part or bottom of the oven, and within the walls

page_text: of the oven; it being understood that similar, or substantially similar, modes of
arrangement and carrying the burners may be applied in connection with other
apparatus heated by gas in an analogous or similar way.
According to this invention, the burners are loosely mounted, and in some cases
are arranged, say, one on either side; and they are supported at one end, say the
back end, by fitting and resting in a socket, or other suitable support; while at the
other end, the front end, they are carried by the pipe which supplies the gas to
them, by suitable carriers or devices which slip over the said pipe, upon the side of
which, nearest the burners, the burner ends rest; while the other side (in the case
of the pipe being round) is steadied or held by bearing upon a part of the oven
wall the gas-pipe itself passes through the side walls of the oven.
:
The nipples which supply the gas from the pipe to the atmospheric burners,
direct the gas horizontally into a tube lying parallel with the burner tube in which
the burner nozzles or holes are provided; and it may be formed thereon at the
back of such tube, the entrance to the tube being constructed to admit the necessary
air for admixture with the gas.
The improvements the subject of this invention, are illustrated in the accompanying
drawings, in which
Figure 1 is a sectional plan taken through the bottom of an ordinary gas oven or
cooker, with my improvements applied thereto.
Figure 2 is a sectional elevation of Figure 1. And Figure 3 is a detail shewing
the front end of the burner and carrier thereof.
In the drawings, a represents the wall or casing of the oven or cooker, and bis
the gas supply pipe, which is disposed at the front part of the oven or cooker, and
passes through the side of the oven and so supported. c are the burners, one of
which is placed at either side of the oven, and are the nozzles in the gas pipe b
which supply gas to the burners.
The burners consist of a main tube, and a tube cat the back of the main tube,
into which the air and gases are introduced. The front ends of the burners are
supported by the carrier devices d on the front side of which the end of the burner
rests, as shewn. The sides of the carrier devices d have holes in them, as shewn,
and by means of these holes they slip over and are adapted to be supported by the
pipe and the sides of the carriers are carried down, as shewn, to the bottom of
the pipe b, in a form corresponding with that of the mixing tube c of the burner, so
as to constitute a suitable seat and support for such tube on which it rests, as shewn
in Figure 2. The opposite end of these carrier devices bears on the underside
of a part al on the casing of the oven, and so holds them in proper position, that is,
prevents them from being turned round on the pipe by the weight of the gas
burners on the opposite side. The other ends, c, of the burners fit in and are
supported by suitable corresponding socket piece a² on the oven casing.
The gas from the nozzles is directed into the open end of the back tube c¹ of
the burner c, from whence it passes into the main tube, and so to the flame
nozzle c².
To place a burner in position, the end c³ is first placed in its socket a², and then
the front end is placed or dropped into its seat in the carrier d. Then to take the
burners out of place, the same action has to be performed, but of course in reverse
order.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvement connected with gas heated ovens or similar gas heated
apparatus having loose burners, consisting of the burner c and carrier device d
mounted in and supported by the gas pipe b; substantially as herein set forth.
2. The arrangement and construction of parts of gas heated ovens or cookers,
consisting of the loose burners c with back mixing tubes c', carriers d, gas pipe
supporting said burner carriers, the means of holding the carriers & in position at

page_text: the front end by the casing a, and the back end supporting sockets a²; all
particularly as set forth with reference to and shewn in the drawings.
