Improvements in and relating to the Grids of Grilling Apparatus and
the like.
We, THOMAS FLETCHER, of Thynne Street, Warrington, Manufacturer of Gas
Apparatus, WILLIAM RUSSELL, of the Scotia Foundry, Pendleton, Iron Founder,
and FLETCHER RUSSELL AND COMPANY, LIMITED, of Thynne Street, Warrington,
Manufacturers of Gas Apparatus and Iron Founders, all in the County of Lan-
caster, do hereby declare the nature of this invention to be as follows:-
This invention relates to the grids of grilling apparatus, the shelves of ovens
and the like, and its principal object is to so construct and arrange them that
they may be readily advanced towards or removed from the source of heat to
which they are exposed and so that they may be securely held in any desired
position.
These improvements are equally applicable to all kinds of grids and shelves but
we will only describe their application to the grid of a grilling apparatus.
Each of two opposite sides of the grid is supported upon the upper ends of two
crossed levers which are pivotted or otherwise suitably movably connected together
at or about the middle of their lengths, so as to be capable of folding upon or
opening out from each other. The lower ends of each pair of crossed levers rest
upon or are connected to the frame or other suitable part of the grill. By folding
the pairs of levers upon themselves the grid is lowered; by opening them out the
grid is raised.
To enable the raising and lowering to be easily and readily performed one of
the lower ends of each pair of levers is furnished with a suitable handle and is
capable of being moved towards or away from the other lower end of the same pair.
These movable lower ends are formed to engage with a series of fixed recesses
or the like, as for example, with a series of ratchet teeth so that the crossed levers
are held in any position in which they may be placed. To raise or lower the grid
the lever ends are disengaged from the teeth and moved to the desired point. This
movement may conveniently be effected by giving the lever ends a lateral motion,
then sliding them along to the required distance and causing them to again engage
with the teeth by a lateral movement in the opposite direction to the first.
One of the upper ends of each pair of levers is connected to the grid in such a
manner as to be capable of movement thereon as the levers are folded or unfolded,
or the grid may simply rest upon the upper ends of the levers, or be pivotted to
one end of each pair and rest upon the other, lateral movement being, if desired,
prevented by projections or guides.
The handled ends of the levers may be connected together so that motion given
to one is communicated to the other."

We, THOMAS FLETCHER, of Thynne Street, Warrington, Manufacturer of Gas
Apparatus, WILLIAM, RUSSELL, of the Scotia Foundry, Pendleton, Iron Founder,
and FLETCHER RUSSELL AND COMPANY, LIMITED, of Thynne Street, Warrington,
Manufacturers of Gas Apparatus and Iron Founders, all in the County of Lan-
caster, 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 relates to the grids of grilling apparatus, the shelves of ovens
and the like, and its principal object is to so construct and arrange them that
they may be readily advanced towards or removed from the source of heat to
which they are exposed and so that they may be secured in any desired position.
These improvements are equally applicable to all kinds of grids and shelves but
we will only describe their application to the grid of a grilling apparatus.
In order that our invention may be more readily understood we have hereto ap-
pended a sheet of drawings which illustrate part of a gas griller embodying these
improvements and to which we will hereinafter refer."
Figure 1 shows the grid and its accessories in plan.
Figure, 2 represents it in side elevation and in a raised position.
Figure 3 illustrates the device by means of which the grid is securely held in
any desired position.
The grid A is supported at each of two opposite sides upon the upper ends of
two crossed levers B, B1, which are pivotted or otherwise suitably movably con-
nected together as at C so as to be capable of folding upon or opening out from
each other. The lower ends of each pair of crossed levers rest upon or are connected
to the frame D or other suitable part of the grill. In the arrangement shown the
lever or arm B¹ has its lower end pivotted to the frame and its upper end pivotted
to the grid A, while the other lever B has its upper end free to move in a slot or
other convenient part of the grid and its lower end at the point E free to move
along the frame for a limited distance. The lower end of this lever is furnished
with a handle F. It will of course be understood that although only one pair of
levers can be seen in Figure 2, there is another similar pair at the other end of
the grid. It is evident that by moving the levers in one direction the grid will
be raised and that by moving them in the opposite direction the grid will be lowered.
To enable the raising and lowering to be easily and readily performed the
handled ends of the levers are moved towards or away from the lower ends of
the other levers. The raising may most conveniently be accomplished by press-
ing downwards upon the handles, when the part E of each lever B acts as a
sliding fulcrum and raises the other end, moving the lever B¹ with it. The handled
ends of the levers are formed to engage with a series of ratchet teeth or the like
so that the crossed levers and the supported grid may be held in any position
in which they may be placed. To raise or lower the grid the lever ends are dis-
engaged from the teeth and moved to the desired point.
A convenient form of retaining device is illustrated by Figures 1 and 3. At
each end of the grill frame is a row of ratchet teeth G opening laterally, into a
groove or slot H. By moving the lever ends E sideways suitable projections or
teeth J formed upon them may either be engaged with the teeth or occupy positions
in the grooves H. When they are in the grooves the levere and the grid are free
to move. The grid may be securely locked in any desired position by moving
the projections J into engagement with the teeth G.

page_text: The handled ends of the levers may be connected together so that motion
given to one is communicated to the other.
When desired the grid and its levers may be lifted and turned over or almost
over by raising the handles F, when the system of levers and the attached grid
will move on the lower pivots of the levers B¹.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a grilling apparatus or the like, a grid or shelf mounted upon the ends
of crossed levers, substantially as and for the purpose hereinbefore described and
as illustrated by the accompanying drawings.
2. In a grilling apparatus or the like, the combination with a grid or shelf
of two pairs of crossed levers, constructed arranged and operated substantially as
herein before described and as illustrated by the accompanying drawings.
