Improvements in Gas-grillers and Grilling Devices of Gas Heated
Culinary Apparatus.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington, in
the County of Lancaster, Gas Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has reference, more particularly, to gas heated grillers or
culinary apparatus heated by gas, in which grilling or similar articles or plates
are used; and the invention has for its object to provide improvements in or
connected with such grillers or apparatus, by which the grids, bars, or plates of
the apparatus can be readily taken out and removed for cleaning or repairs by
those more or less skilled in the use of culinary apparatus, but, at the same time,
cannot be taken out and removed by the ordinary users, without special knowledge
of their construction.
into a
According to this invention, the grids or bars of the grilling apparatus or device
are detachably fitted in a frame, in which they lie; and are provided with a stud
or projection at two of the corners, one of which fits into a groove, slot, or recess,
or under a projecting part of the frame at one side or end, while the other fits
simple hole or socket. By these, the grid is prevented from being lifted
bodily out when in its normal position in the frame; while, at the same time, it
cannot be slid bodily out or along the frame or canted within it; and it can only
be taken out by first moving or revolving it up about the projections or studs in
the manner of a hinge door, or the like, and then moving one end along the slot
or groove at one end, the other projection or stud remaining in its socket. By this
movement, the projection or stud on the end moved, will come out of the slot or
groove, when the grid or device can be lifted up, and the other stud or projection
drawn out of the socket; the whole thing is then free of the frame.
According to one form, in a rectangular griller or grilling arrangement, the
grid plates or grids will be arranged along each side, fitting in the seat provided
for them in the frame; while the burner will be disposed down the centre below,
or within a space, between the adjacent edges of these grids. At the outside
corners of these grids or plates, the projections or studs will be provided; and,
in the edge of the frame seat, adjacent to one end of each of the grids or plates,
the slots or grooves are provided. These slots or grooves at their inner end may
be so made as to form a semi-circular, or similar socket, or receive and hold the
studs or projections of the grids; and the studs or pins, in taking out the grids,
would have to be first lifted up out of this socket, over the metal which is formed
on the inside of it: and then along the slot towards the centre of the grilling
device or apparatus, where the slot or groove may be made of the larger area.

arrangement, or form of grilling apparatus, or the parts, just specified.

Improvements in Gas-grillers and Grilling Devices of Gas Heated
Culinary Apparatus.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington, in
the County of Lancaster, Gas Engineer, 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, more particularly, to gas heated grillers or
culinary apparatus heated by gas in which grillers or similar articles or plates
are used; and the invention has for its object to provide improvements in or
connected with such grillers or apparatus, by which the grids, bars, or plates of
the apparatus can be readily taken out and removed for cleaning or repairs by
those more or less skilled in the use of culinary apparatus, but, at the same time,
cannot be taken out and removed by the ordinary users, without special knowledge
of their construction.
According to this invention, the grids or bars of the grilling apparatus or device
are detachably fitted in a frame, in which they lie; and are provided with a stud
or projection at two of the corners, one of which fits into a groove, slot, or recess,
or under a projecting part of the frame at one side or end, while the other
fits into a simple hole or socket. By these, the grid is prevented from
being lifted bodily out when in its normal position in the frame; while, at
the same time, it cannot be slid. bodily out or along the frame or canted
within it; and it can only be taken out by first moving or revolving it up about
the projections or studs in the manner of a hinge door, or the like, and then
moving one end along the slot or groove at one end, the other projection or stud
remaining in its socket. By this movement, the projection or stud on the end
moved, will come out of the slot or groove, when the grid or device can be lifted
up, and the other stud or projection drawn out of the socket; the whole thing is
then free of the frame.
According to one form, in a rectangular griller or grilling arrangement, the
grid plates or grids will be arranged along each side, fitting in the seat provided
for them in the frame; while the burner will be disposed down the centre below,
or within a space, between the adjacent edge of these grids. At the outside
corners of these grids or plates, the projections or studs will be provided; and,
in the edge of the frame seat, adjacent to one end of each of the grids or plates,
the slots or grooves are provided. These slots or grooves at their inner end may
be so made as to form a semi-circular, or similar socket, or receive and hold the
studs or projections of the grids; and the studs or pins, in taking out the grids,
would have to be first lifted up out of the socket, over the metal which is formed
on the inside of it; and then along the slot towards the centre of the grilling
device or apparatus, where the slot or groove may be made of a larger area.
Of course it will be understood the invention is not restricted to the particular
arrangement, or form of grilling apparatus, or the parts, just specified.
The annexed drawings illustrate the invention; in these. Figure 1 is a plan of
a gas grilling apparatus with my improvements applied to it, with a part removed;

page_text: Figure 2 is a view shewing one end with this part fitted; and Figure 3 is a
side elevation of the slotted part viewed from the inside. In these drawings, a
are the grids of the apparatus, having at their two outer corners studs or
trunnions b, one of which fits in a suitable socket hole in the frame c of the grill;
and the other into the slotted or grooved part d along which it is free to move.
In the centre between these two grids or plates, the burner e is disposed, lying at
a lower level than the plates.
As will be seen from Figure 3, the slotted parts & are provided at each end
with a semi-circular socket or seat at dat each corner, in which the studs or
trunnions of the grids a normally lie; while the end of the burner e rests in a
similar recess or socket at 2. The slotted or grooved part, in the case illustrated,
consists of a separate fitting projecting from the side frame c of the apparatus
as shewn and comprises a lower part in which the grid seats and slots proper
are provided, as described, and an upper part forming a cap or cover to them.
This, in Figure 1, is removed, but in Figure 2 is in place; and at the centre it
is provided with a gap at through which the trunnions may be moved when
removing the grids.
The grids a may be moved up and down about their trunnions by a lever f
and oscillating shaft g, having upon it pins g', and projecting from it directly
under the grids. When the grids are used for grilling, they will be held up in a
horizontal position as shewn in the drawings, by the pins g¹, when the flames
issuing from the sides of the burner e will pass up through the openings in the
grids. Then when it is to be used for boiling, the grids are lowered by turning
down the pins g₁, when the flames issuing from the sides of the burner will be
above the grid edges.
Normally, when the grids are in their position for use, they cannot be taken.
out of their supports, for the reason that one edge is level with, or below the level
of the frame c, and so that the movable trunnions cannot be moved along the
slots about the socket hole of its opposite trunnions; but by lifting and revolving
the grid about its trunnions to a vertical position, or nearly so, the trunnions b
can be moved along the slots (the sockets at the other end being sufficiently
large to allow this): and when this trunnion is opposite the gap it can be
lifted up through it; and then the whole grid withdrawn; and when putting
them in place again, the converse procedure must be adopted.
The end of the burner e can also be lifted up direct through the gap d.
In the case shewn, the grids a occupy only a portion of the grilling apparatus,
of which e represents the frame.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. The herein described improvement in gas grillers or grilling devices of gas
heated culinary apparatus, consisting of grids or plates mounted, and adapted to
be removed, or put in place; substantially as in the manner herein set forth.
2. In gas grillers, the plates a having studs or trunnions b, one mounted in a
socket, and the other supported on a seat and free to be moved along a slot or
groove, d, substantially as and for the purposes set forth.
3. The gas grilling device having parts arranged, constructed, and adapted to
operate, particularly as set forth with reference to and shewn in the drawings.
