I, GEORGE FREDERICK WILLIAMSON, of Midland Foundry, Midland Road,
Wellingborough, in the County of Northampton, Ironfounder, do hereby declare the
nature of this invention to be as follows:-
This invention for improvements in kitchen ranges has for its object to provide
an improved arrangement of fall bar or table closing the top part of the front fire-
bars whereby the vertical depth of the fire is increased for roasting or toasting
purposes or the like; and consists in continuing the front firebars the full height
of the fire-basket and in arranging the drop bar or table in such manner that it
can be slid upwards to the top of the top plate of the range and then rotated into
the horizontal position and be retained in this position to form a table or can be
slid upwards to remove the table from the range.
In one way of carrying out this invention, the side frames of the front bars are
provided at their upper parts with grooved brackets or projections and pins or
projections in the sides of the drop table slide in the grooves. These grooves are
arranged to the front of the firebars or so that the fall bar clears the nosing of
the hot plate of the range. Projections on the fall bar engaging with corresponding
projections on the range keep the fall bar vertical when in its lower position and
horizontal when in its highest.
An inclined groove leads from one of the grooves in the brackets to the outside
so that the fall bar can be easily removed or re-inserted.
In another arrangement, the fall bar ordinarily covers only a small portion of the
top of the firebars but is made telescopic or expansible so that it can be drawn out
when in its horizontal position to form a larger table.

I, GEORGE FREDERICK WILLIAMSON, of Midland Foundry, Midland Road,
Wellingborough, in the County of Northampton, Ironfounder, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained, in and by the following statement:
This invention for improvements in kitchen ranges has for its object to provide
an improved arrangement of fall bar or table closing the top part of the front fire-

page_text: bars whereby the vertical depth of the fire is increased for roasting or toasting
purposes or the like; and consists in continuing the front firebars the full height of
the fire-basket and in arranging the drop bar or table in such manner that it can
be slid upwards to the top of the top plate of the range and then rotated into the
horizontal position and be retained in this position to form a table, or can be slid
upwards to remove the table from the range.
In one way of carrying out this invention, the side frames of the front bars are
provided at their upper parts with grooved brackets or projections and pins or
projections in the sides of the drop table slide in the grooves. These grooves are
arranged to the front of the firebars or so that the fall bar clears the nosing of
the hot plate of the range. Projections on the fall bar engaging with corresponding
projections on the range keep the fall bar vertical when in its lower position and
horizontal when in its highest.
An inclined groove leads from one of the grooves in the brackets to the outside
so that the fall bar can be easily removed or re-inserted.
In another arrangement, the fall bar ordinarily covers only a small portion of
the top of the firebars but is made telescopic or expansible so that it can be drawn
out when in its horizontal position to form a larger table.
In the accompanying sheet of illustrative drawings: Fig. 1 is a front elevation
of part of the front of a kitchen range fitted with a fall bar constructed according
to this invention and showing the fall bar in its vertical position, and Fig. 2 is a
similar part view showing the fall bar horizontal, Fig. 3 is a plan of the same,
Figs. 4 and 5 are side elevations of the brackets and cam grooves in the sides of
the front frame in and on which the fall bar works.
At
Fig. 6 is a front elevation showing the telescopic fall bar and Figs. 7 and 8 are
side elevations showing the brackets and cam grooves in which this fall bar works.
The front bars a are pivotted at the top in the holes 6 in the front frame c.
the top, the frame c is formed on either side with a projecting bracket d. The
brackets d are each provided with a recess e widening out at the top and bottom,
and one bracket has an inclined groove f leading out from the recess.
One or
both brackets has a groove g at the top. The faces h of the frame c project beyond
the face of the bracket d.
The fall bar i is provided at either end with a pivot pin and near the pin with
cam faces m m¹ working against the projecting faces h of the frame c.
At or near
its top the fall bar is provided on one or both sides with projections n adapted to
take into the top groove or grooves 9 of the bracket. The front face of the bars
is provided with a square hole o by which it can be manipulated by the squared
end of a bent poker.
The operation is as follows: -To insert the fall bar, the fall bar is held approxi-
mately vertical and the pin of the corresponding side is inserted in the recess e
without the groove f, and then the other pin 7 is slid down the groove f into its
recess e. The fall bar can then be slid down between the faces h to the bottom of
the recess and is held vertical with the projection n taking into the groove g.
At
the same time, the cam faces m at its lower end are forced outwards
by the faces h and rigidly hold it in position. To bring the fall
bar horizontal it is raised until the pins are at the top of the recesses e and is
then turned horizontal, it being retained horizontal by the cam faces m¹ at right
angles to the faces m bearing against the top of the faces h.
The fall bar is removed by turning it to the vertical position with its pin opposite
the groove and the pin at this end is slid up the groove f.
In the modification shown in Figs. 6 to 8, the action of the fall bar is the same
but it is made telescopic, so that when vertical its depth is considerably reduced
and exposes more of the face of the fire. In this case however it is retained both
in the vertical and horizontal position by the action of the cam faces m m¹ on the
faces alone.
The fall bar is made in two parts, the main part i and the front part ¹ sliding

page_text: over the face of the part i, its edges running in grooves as clearly shown. The
screw or stop prevents the front part being entirely drawn out.
The recesses e in the brackets d are straight and short just sufficient to enable
the fall bar to be raised for its face m to clear the projecting part of the face h
when desired to rotate it into the horizontal position. When rotated into the
horizontal position the face m¹ bears against the same projecting part of the face h.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A fall bar for the front bars of a kitchen range adapted to be placed vertical
to cover the top of the front bars or to be slid upwards and rotated into the horizontal
position.
2. The improvements in fall bars substantially as described with reference to
Figs. 1 to 5 of the drawings.
3. A telescopic fall bar for a kitchen range adapted to be placed vertical to cover
the top of the front bars or to be rotated into the horizontal position and expanded
to form a table.
4. The improvements in fall bars substantially as described with reference to
Figs. 6 to 8 of the drawings.
