We GEORGE GORDON BRODIE of Catherine Street Aston Birmingham Ironfounder
and JAMES DAMREL PRIOR of 143 Isledon Road Finsbury Park London Manager do
hereby declare the nature of this invention to be as follows:
-
The provision of simple and efficient means of varying at pleasure the capacity form
and position of the fire grate in cooking or other ranges so as to meet the varying
requirements of culinary and other operations in which heat is employed and this
object is attained in the manner hereinafter described.
We construct the front of the grate of vertical or horizontal bars either curved or
straight. The bottom of the grate which is distinct from the front of the grate rests
at the back of it on the top of projections formed on the sides or back of the fire box
or on a suitable bracket and in front is provided with a handle or socket protruding
through the front bars which handle or socket carries a pawl which engages with a
series of notches formed on the front bars or front plate so as to retain the bottom at.
any desired height.
The bottom of the grate can be raised or lowered by means of the handle or socket
and either pivots on the projections before referred to if the front bars are curved to
the proper radius or if the front bars are straight or improperly curved the bottom
grating slides backwards or forwards on the said projections so as to compensate for
the deviation of the front bars from the proper radius.
The front edge of the bottom grate is kept in contact or nearly so with the inside
surfaces of the front bars as it is raised or lowered by means of suitable guides.
For convenience in emptying the fire box of ashes the bottom grate can be dis-
engaged from the notches in front and allowed to drop down and is provided with lugs
cast on at the back of the grate which catch on the projections and prevent its falling
out of position.

and JAMES DAMREL PRIOR of 143 Isledon Road Finsbury Park London Manager 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 state-
ment-
The provision of a simple and efficient means of varying at pleasure the capacity
form and position of the fire grate in cooking or other ranges so as to meet the vary-
ing requirements of culinary and other operations in which heat is employed and this
object is attained in the manner hereinafter described.
We construct the front part of the grate of vertical or horizontal bars either curved
or straight. In the accompanying drawings Figure 1. represents a vertical section of
a grate constructed according to our said invention and Figure 2. is a front view of
the same.
The bottom of the grate A. which is distinct from the front of the grate
rests at the back of it on the top of projections B. B. formed on the sides or back of
the fire box, or on a suitable bracket attached to the front plate of the fire grate, and
in front is provided with a handle or socket protruding through the front bars, which
handle or socket may be of a similar construction to that described and illustrated in
the specification of the said James Damrel Prior No. 1843 A.D..1877 engaging in a
series of notches as therein described, so as to retain the bottom at any desired height,
or the bottom of the grate A. is provided with a handle or socket C. protruding
through the front bars as shown in the accompanying drawings engaging in a series
of notches as shown. The bottom of the grate A. can be raised or lowered by means
of the handle or socket and either pivots on the projections B. B. if the front bars are
curved to the proper radius, or if the front bars are straight or improperly curved the
bottom A. slides backwards or forwards on the projections B. B. so as to compensate
for the deviation of the front bars from the proper radius. The front edge of the
bottom of the grate as it is raised or lowered is kept in contact or nearly so with the
inside surfaces of the front bars by means of suitable guides. For convenience in
emptying the fire box of ashes the bottom grate can be disengaged from the notches
in front and allowed to drop down and is provided with lugs D. cast on at the back of
the grate which catch on the projections B. B. and prevent its falling out of position.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that we claim is :
1. The projections B. B. operating as a support or pivot for the back portion of the
inovable bottom substantially as hereinbefore described and illustrated.
