page_text: I, GEORGE ERNEST WRIGHT, of Olton Hall, Solihull, in the County of Warwick,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
In the hot plates of gas cooking stoves as ordinarily made the top of the hot plate
is fixed and access to the burners situated on the underside of the hot plate can
only be had by the unscrewing of the said top.
In order to give facility of access to the burners I connect, according to my
invention, the top of the hot plate to the body of the same by a hinge joint so
that the said top can by being turned on the said hinge joint be either raised into
a vertical plane so as to give free access to the burners for removal, replacement
or repair, or shut down into its normal horizontal position. In order to fix the
top of the plate in its horizontal position a weighted hook catch turning on a pin
at that side of the body of the hot plate on which the free edge of the top shuts
down may be employed. When the top is shut down a fixed hook on its under-
side bearing on the inclined top of the hook catch presses the said catch back, and
when the top has reached its lowest or horizontal position the fixed hook on its
underside snaps under the hooked top of the hook catch and fixes the top of the
hot plate in position. When it is wished to raise the top it is only necessary to
press the weighted lower end of the hook catch when its upper end is disengaged
from the fixed hook on the underside of the top and the said top may be raised.
I connect the burners to the hot plate essentially in the following manner.
The vertical pipes by which the several jets are supplied with inflammable gas
terminate in horizontal fixed nozzles situated in recesses in the side of the hot
plate. The tail end of the horizontal pipe carrying the burner terminates in a
small flat plate which plate when the burner and its pipe are placed in position
fits and closes the top of the recess in the side of the hot plate thereby forming a
small chamber closed excepting at its bottom side. The horizontal gas nozzle
delivers a jet of inflammable gas in the axis of the pipe carrying the burner which
jet of gas from its axial position becomes uniformly mixed with the air entering
the bottom of the small chamber described. The connection of each of the gas
pipes is effected in the way described.
I wish it to be understood that I do not limit myself to the particular arrange-
ment described of carrying this part of my invention into effect the essence of this
part of my invention consisting in supporting the tail end of the burner upon
the same carrier that supports the horizontal gas nozzle.

page_text: I, GEORGE ERNEST WRIGHT, of Olton Hall, Solihull, in the County of Warwick.
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
In the hot plates of gas cooking stoves as commonly made the top of the hot
plate is fixed and access to the burners situated on the underside of the hot plate
can only be had by the unscrewing of the said top.
In order to give facility of access to the burners I connect, according to my
invention, the top of the hot plate to the body or frame of the same by a hinged
joint so that the said top can by being turned on the said hinged joint be either
raised into a vertical plane so as to give free access to the burners for removal
replacement or repair, or shut down into its nornial horizontal position. In order
to fix the top of the plate in its horizontal position a weighted hook catch turning
on a pin at that side of the body of the hot plate on which the free edge of the top
shuts down, may be employed. When the top is shut down a fixed hook on its
underside bearing on the inclined top of the hook catch presses the said catch
back, and when the top has reached its lowest or horizontal position the fixed
hook on its underside snaps under the hooked top of the hook catch and fixes the
top of the hot plate in position. When it is wished to raise the top it is only
necessary to press the weighted lower end of the hook catch when its upper end
is disengaged from the fixed hook on the underside of the top and the said top
may be raised.
I connect the burners to the hot plate essentially in the following manner.
The vertical pipes by which the several jets are supplied with inflammable gas
terminate in horizontal fixed nozzles situated in recesses in the side of the hot
plate. The tail end of the burner barrel terminates in a small flat plate which
plate when, the burner and its pipe are placed in position fits and closes the top
of the recess in the side of the hot plate thereby forming a small chamber closed
excepting at its bottom side. The horizontal gas nozzle delivers a jet of
inflammable gas in the axis of the burner barrel which jet of gas from its axial
position becomes uniformly mixed with the air entering the bottom of the small
chamber described. The connection of each of the burner barrels is effected in
the way described.
I wish it to be understood that I do not limit myself to the particular arrange
ment described of carrying this part of my invention into effect, the essence of
this part of my invention consisting in supporting the tail end of the burner
upon the same carrier that supports the horizontal gas nozzle.
Figures 1 and 2 of the accompanying drawings represent in plan and side
elevation respectively (the latter partly in section) the hot plate of a gas cooking
stove containing my improvements, the hinged top of the hot plate being in its
normal position.
Figures 3 and 4 are similar views, to Figures 1 and 2 the hinged top of the
hot plate being in its raised or turned up position.
Figure 5 is an elevation of the opposite side of the hot plate to that represented
in Figure 2.
Figure 6 is a section on the line x, x Figure 1.
Figure 7 is a plan of the hot plate with the hinged top and burners removed and
Figures 8, 9, 10, 11, 12, 13 and 14 represent details of the hot plate; Figures 9
to 14 both inclusive being drawn to a larger scale than the other figures of the
drawings.

page_text: The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the top of the hot plate hinged at 6 to the frame c, c¹ of the same. The said
frame c, c is provided with a weighted catch d which when the hinged top a is
in its normal or shut down position engages with a hook or projection a³ on the
underside of the hinged top a but other fastening means may be employed.
When it is wished to raise the hinged top a of the hot plate to gain access to
the burners for cleaning, removal and repair it is only necessary to turn the
weighted catch d on one side, as indicated in dotted lines in Figure 4, so as to
unhook or disengage it from the hook a when by lifting the hinged top a it may
be readily turned into the position represented in Figures 3 and 4.
The bars c', c¹ of the frame c, c¹ constitute the carriers for the nozzles k of the
gas supply pipes and also for the hot plate burners e, f, fg, h and i the said
burners being supported at their tail ends by the gas nozzle carrier bars c¹, c¹
in the way hereinafter particularly described.
The carrier bars c', c¹ of the frame are provided with recesses at the parts where
the gas nozzles are screwed into the said bars and the burners e, f, f and h are
provided with flat plates e², f2, f and h² which take on the top edges of the recessed
parts and close the top of the said recesses. The recessed parts of the bars c¹
thereby constitute the support for the tail ends of the burners e, f, f and h, the
recesses which are closed excepting at bottom constituting the mixing chambers
for the inflammable gas and air to be consumed by the burners, the gas being
delivered by the nozzles k. k in the line of the axis of the burner tubes. The
other ends of the burners e, f, f and h are supported by the intermediate web or
plate shown separately in Figure 8.
Where the burners are unsupported at their outer ends as in the case of the
burners and the burners are provided with a flange marked respectively g' and ¹
at their tail ends which engage or take in dovetail like recesses formed on the
carrier bars c', c¹. The tops of the recesses or mixing chambers in these cases
may be made in one piece with the carrier bar c¹ as illustrated with respect to the
burner (see the enlarged views of the same Figures 12 13 and 14, Figures 12
and 13 showing the burner g applied to the carrier bar and Figure 14 showing
the burner detached); the closing tops of the recesses may be altogether
dispensed with as illustrated with respect to the burner i.
Gas is supplied to the gas nozzles of the burners e, f, f, g and h from the
main pipe and gas is supplied to the gas nozzle k of the burner i by the
supplementary pipe n¹.
Accidental displacement of the hot plate burners is prevented when the top a
of the hot plate is shut down by the said hinged top closing on short uprights, webs
or projections m on the burners. Instead of webs m on the burners equivalent
parts may be arranged on the underside of the hinged top for bearing directly on
or engaging with the hot plate burners for effecting the same object.
I wish it to be understood that the means of attaching or supporting the tail
ends of the hot plate burners to or upon the gas nozzle carrying bars c¹ c¹ may
be varied without departing from this part of my invention.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that I claim as
my invention of "Improvements in the hot plates of cooking stoves":—
First. Connecting the tops of the hot plates of gas cooking stoves to the bodies
or frames of the hot plates at one side by a hinge joint for the purposes and sub-
stantially as herein before described and illustrated in the accompanying drawings.
Secondly. Hinging the top of the hot plate to the body or frame of the hot
plate and combining therewith a weighted hooked catch or its equivalent to secure
or fasten the top of the plate when in its shut down position substantially as
herein before described and illustrated in the accompanying drawings.
Thirdly. Supporting the tail or rear ends of the hot plate burners of gas cooking

page_text: stoves upon the carrier that supports the horizontal gas nozzles substantially as
herein before described and illustrated in the accompanying drawings..
Fourthly. Making in the gas nozzle carrier bars of the hot plates of gas cooking
stoves, recesses closed at top but open at bottom or open at top as well as at bottom,
the open top in the latter case being preferably closed by a flat plate carried
by the gas burners, the said recesses constituting the mixing chambers for the
inflammable gas and air passing to the burners substantially as hereinbefore
described and illustrated in the accompanying drawings.
Fifthly. Preventing the accidental displacement of the hot plate burners by
arranging on the burners, webs, projections or their equivalents on which the
shut down hot plate bears or by providing the hot plate with webs, projections
or their equivalents which when the hot plate is shut down bear on or engage with
the burners substantially as hereinbefore described and illustrated in the,
accompanying drawings.
