PROVISIONAL SPECIFICATION.
Improvements in and connected with the Fire-bars and Fire-bar
Frames of Kitchen Ranges and the like.
We, JOHN GREEN and WILLIAM ROWLAND GREEN of Norfolk Works,
Ecclesfield in the County of York, Ironfounders, and ILRBERT HAGUE of
Prospect Cottage, The Cross, Ecclesfield aforesaid, Pattern Maker, do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to provide or effect certain improvements in and
connected with the fire-bars and fite-bar frames of kitchen langes and the like
these bars are sometimes cast in one piece with the bar frame, but our invention is
designed to make, by an improved method, the said fine-bars separately, where
required, and to effect such a joint between the sand bars and the bar-frame that
the former may be readily removed if desired, but cannot be knocked out accidentally,
the said Jomt will at the same time allow for the contraction and expansion of the
metal.
In carrying out our said invention we cast or otherwise form on one end of the
fire-bar a stud on projection the sides of which are of rather a sharp pitch, the said
stud fitting in a corresponding 1ccess in the cheek on inside face of the bar frame,
the opposite end of the fire bar fits into a recess of corresponding shape to the end
of the fire-bar in the other inner side or check of the bar-frame, the sharp pitch
or inclined plane of the recess in the stud side of the bar-frame forces the other
end of the bar into its recess. For convenience in removing or replacing the bar
for cleaning or other purposes a slot is formed in the inner side or check of the
bai-fiame, leading to the recess which the full end of the bar fits, the said slot
being of less depth in the metal than the recess, and is of such a shape, in the case
ol a square ended bar, that when taking out the said bar it has to be tuned round
a quarter of a revolution; when removing the bar from the frame it is drawn
slightly to the side cariying the stud so that the latter fits well into its recess and
so as to clear the opposite end of its recess, this end is then passed upwards aud
backwards along the slot before mentioned, and in the case of a square ended bar
it is turned a quarter of a revolution, and drawn clear of the bai frame.
It is evident that our invention may be applied to fire-bars of auy section, but it
1s inore particularly applicable and will probably give the best results when applied
to the square bars of Yorkshire ranges
The various parts of the fire-bar aud fiame may be cast or formed with the aul
of chills, cores or in any other suitable manner.

Frames of Kitchen Ranges and the like.
We, Joux GREEN and WILLIAM ROWLAND GREEN of Norfolk Works,
Ecclesfield in the County of York, Ironfounders, and HERBERT HAGUE of
Prospect Cottage, The Cross, Ecclesfield aforesaid, Pattern Maker, do hereby
declare the nature of this invention and what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement.-
The object of our invention is to provide or cffect certain improvements in and
connected with the fire-bars and bre-bar frames of kitchen ranges and the like,
these bars are sometimes cast in one piece with the bar frame, but our invention is
designed to make by an improved method the said fire-bais separately, where
required, and to effect such a joint between the said bars and the bar frame, that
the former may be readily removed if desued but cannot be knocked out accidentally;
the said Joint will at the same time allow for the contraction and expansion of the
metal.
In describing our invention reference will be had to the sheet of drawings which
form a part of this Specification.
Figure 1 is an elevation of part of the check or inside face of the bar frame as
formed for the reception of the square end of single bars as will be hereafter
explained.
Figure 2 is a vertical section on line "a" "a" of Figure 1 shewing two of the
bais in position.
Figure 3 is a front elevation shewing the application of our invention to a
movable front.
Figure 4 is an elevation of the inside face o cheek of the bar frame used in
fixing the movable front shewn upon Figure 3.
Figure 5 is a vertical section on line """" of Figure 4 shewing the movable
front in position.
In carrying out the first part of our said invention we cast or otherwise form on
one end of the fine bar a stud or projection A the sides of which are of rather a
sharp pitch, the said stud fitting in a corresponding recess B in the cheek or inside
face of the bar frame E, the opposite end of the fire bat fits into a recess D of
corresponding shape to the end of the fine-bar in the other inner side of cheek Fot
the bai fiame, the sharp pitch or inclined plane of the recess in the stud side of the
bar frame forces the other end of the bar to its recess. For convenience in
removing or replacing the bar for cleaning or other purposes a curved slot Gis
formed in the inner side o chcek of the bar frame, leading to the deeper recess D
in which the full end of the bat fits, the said slot being of less depth in the metal
than the recess, and is of such a shape, in the case of a square ended bar, that when
taking out the said bar it has to be turned round a quarter of a revolution; when
removing the bar from the frame it is diawn slightly to the side carrying the stud
so that the latter fits well into its recess B, and so as to clear the opposite end of
ats recess D, this end is then passed upwards and backwards along the slot before
mentioned, and in the case of a square ended bai it is turned a quarter of a
1evolution, and drawn clear of the bar frame.
It is evident that our invention may be applied to fire-bars of any section, but it
is more particularly applicable and will probably give the best results when applied
to the square bars of Yorkshire anges.
We
e may also apply our invention to movable fronts or tied bats, as they are
sometimes called, for ranges and the like and in so doing we cast or otherwise forin

page_text: the said movable fronts with two or more bais II and upon each side or upright
portion of the said fronts we cast two studs K, K₁; upon the inner jambs or
cheeks of the frames intended to receive such a movable front we cast or form two
vertical recesses L somewhat longer than the full length over all between and
including the studs K, K', on the sides of the movable front, a slot M from the
back or inside of the frame to the lower part of each of the vertical recesses L
allows the studs on the movable front to be placed therein, the two top studs Kare
first placed in the said recesses L, and the said studs and movable front are then
drawn up the vertical recesses Land the other pair of studs inserted in the
slots and passed to the bottom of the vertical recesses L. where they bed them-
selves and the front is thus held securely in position. It is well known that the
inner portion of the bottom bai 18 that which wears most quickly and it will
therefore be seen by reversing this movable frout, top to bottom and front to back,
that four different surfaces may be presented to the fire in the same position as the
usual bottom bar; the advantages for cleaning and repairing the giate will also be
apparent.
It is evident also that in such a movable front we may employ vertical fire-bars
instead of horizontal if desired and cast the studs on the tide picces as hereinbefore
stated.
The different studs, slots and recesses being proferably (but not necessarily) cast
with chills as described in Letters Patent No. 790 1894, by so doing the parts are
more easily fitted together and work very smoothly.
Having now particularly described and ascertained the nature of our said inven-
on and in what manuer the same 18 to be performed, we declare that what we
claim is
1. The improved method of securing a five-bar in a fire-bat frame consisting of a
fire-bar with studs A on one end adapted to fit into the recess B in the cheek of
the bar fiame E, the other end C of the said fire-bar being left square or
approximately square and fitting into the inner check F of the bai-frame the said
cheek being recessed at D and having a curved slot G leading thereto substantially
as and for the purposes described and illustrated.
2. The improved method of securing tied bars or movable fionts in a fire bai
fiame the said movable fronts having studs K, K' on the uprights I thereof
adapted to engage slots M and vertical recesses Ĺ substantially as described and
illustiated.
