Improvements in Cooking Ranges.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge Foundry, Ferrybridge, in
the County of York, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to cooking ranges of the kind known as "Eagle" ranges,
which have vertical front bars circularly curved and a bottom grate pivotted at the
back so that, by inserting a bar or poker into a socket at its front, it can be raised
more or less to diminish the amount of fuel above it. In order to retain the
bottom grate firmly in any position to which it is raised, I attach to its back bar,
which turns in bearings, au arm projecting downwards and on the end of this arin
I pivot a lever arm which rests on a stationary bar below. This arm is loaded at
the end and has its under face made with rounded projections and hollows.
When the grate is raised or lowered this lever arm is made to move over the
stationary bar rising and falling as its projections and hollows pass over the bar,
but when the grate is released, it takes such a position that a hollow of the arm is
engaged on the bar, and, unless considerable force be applied, the arm remains in
this condition holding the grate firmly. I prefer to make the hollows on the under
face of the arm less deep the nearer they are to the pivot of the arm where the
load at the end of the arm exerts the greater leverage.
For such ranges as have openings at the side of the fire to oven flues, I prefer
to make the bottom grate curved downwards so that, when it is raised to its highest
position, these openings are still partly above it. Instead of fixing the curved
front grate, I fit it in curved guides so that on removing a stop it can be withdrawn
when required.
Dated this 15th day of July 1893.

Improvements in Cooking Ranges.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge Foundry, Ferrybridge, in
the County of York, 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 :-
My invention relates to cooking ranges of the kind known as "Eagle" ranges,
which have vertical front bars circularly curved and a bottom grate pivotted at
the back so that, by inserting a bar or poker into a socket at its front, it can be
raised inore or less to diminish the amount of fuel above it. In order to retain
the bottom grate firmly in any position to which it is raised I provide a catch as I
shall describe referring to the accompanying drawings
Fig. 1 is a transverse section of the range,
Fig. 2 shews a modified form of catch.
I fix the bottom grate A on a frame B which turns in bearings at B' an arm C
projecting downwards from the frame B and terminating in a toothed segment
engaged by a spring D as shewn in Fig. 1 or by a loaded pawl E as shewn in
Ho

page_text: When the grate is raised or lowered the segment of C is made to move over the
spring or loaded pawl which engages in one or other of the notches holding the
grate unless sufficient force be applied, by inserting the end of a poker or lever
into a socket F in the front part of the frame B.
The teeth of the segment C are rounded so that they ride over the spring or
pawl without shock.
For such ranges as have openings at the sides of the fire to oven flues, I prefer
to make the bottom grate curved downwards as shewn so that, when it is raised to
its highest position, these openings are still above it.
The bottom grate A fits on the frame B on which it is fixed in any suitable
manner so that it may be removed when worn, a fresh grate being substituted
without interfering with the frame B.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In combination with the bottom grate of an "Eagle" cooking range a pivotted
frame to which the grate is removably fixed and which has a toothed segment
engaged by a spring or weighted pawl, substantially as and for the purpose set
forth.
