An improved Fire Grate.
1, ARTHUR SCOTT of Perth in the Colony of Western Australia, Accountant,
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 :-
The objects of this invention of a revolving and detachable fire grate are
Firstly for the purpose of providing a fire grate or box that will act in such a
manner by rotating as to be usable in common or interchangeable to two or more
rooms in a house or other building that is :-the same fire grate and fire therein
can be used for heating two or more rooms, but at differently desired times and
Secondly for the purpose of providing a grate that at will can be attachable and
detachable respectively to, and from the permanent or fixed portion of the grate
frame so that the grate or fire box proper can be removed with the fire alight
therein from room to room and attached on to any other grate frame that is made
and constructed according to this invention.
The use of this invention will result in houses being heated on A more
economical and convenient basis than at present existing by the use of the
ordinary fixed grate and which latter necessitates the lighting of the fire in the
room in which it is desired to be used and enjoyed, the initial lighting of same
being made to the discomfort and inconvenience of those who at the time being
may be occupying the room in question.
Further by means of this invention a fire which has been alight for some time in
one room can be subsequently utilised for the immediately adjoining room without
carrying or relighting it, by simply rotating the grate as a whole sufficiently far,
so as that the box containing the fire, will occupy its position in said adjoining
room where the fire is desired to be used, also the process of cleaning and arranging
the grate either preparatory or subsequent to the lighting of the fire in the room
in which the fire is intended to be, or has been used is hereby obviated.
The invention essentially consists :-
Firstly-In having the fire grate constructed so that it will revolve or rotate
on an axis or pivot (either partially or wholly) and in a plane horizontal to the
floor of the room and secondly in having the fire grate or box so made that
it may be easily attachable to or detachable from the main central axial or pivotted
frame.
In order that my invention may be clearly understood, reference may be made
to the accompanying drawings which form part of this Specification and are to be
read therewith and which illustrate my invention and its application either as regards
the double or single form of grate.
In these drawings.
Figure 1. is a sectional elevation of the invention showing a double form of
grate either of which is usable or interchangeable for either of the rooms A.
and B.
Figure 2. is a plan, the chimney or flue being denoted by dotted lines.
Figure 3. being side and front views showing the method of release and

page_text: C. represents the central pivotted or axial frame preferably made hollow and of
a truncated cone shape which may be of any angle or incline. A cup or boss C
is formed on the underside of the frame by means of which it works or rotates
on the axial pin or bearing C³ which is secured to the floor in any approved
manner.
The frame is held in vertical and correct position by means of the projection C
formed on its upper part, said projection working and being held in the bearing C,
which is suitably affixed to the arch or other part of the permanent chimney or
flue as the case may be.
The grate proper or fire box D. is hung or othewise held on the aforesaid
central pivot C. in an easily attachable and detachable manner by means of the
lug or Hange D formed thereon and which fits into a correspondingly shaped
projection D formed on the pivot frame C.
The weight of the grate and its contents being sufficient to hold it secure in
position.
The release and retention mechanism as shown consists of a bar E. placed
transversely in the chimney wall, said bar being held by the guides E' and provided
with handles or knobs E and E at its ends. On this bar at about a central
position is formed a projection or finger E' which engages with and between
corresponding lugs or projections E' formed underneath at both sides of the outer
ring of the fire grate.
The method of using my invention is as follows:-
Assume that it is desirable for sake of economy or convenience either to utilise
a fire for room B. which may be already. alight in room A. or that a fire should be
ignited in room A. for use in room B. In this latter case upon the fire being
sufficiently alight upon a partial rotation being given to bar E. by knob Es
sufficiently so that it will cause the finger E to disengage with the lugs Eas
before described, resulting in the grate D. being released from its fixed position so
that upon a slight pressure being given to the latter, it will revolve sufficiently far
on its axial points C and C+ that the grate D. will occupy a position in room B.
similar to that which it occupied in room A. in which position it is retained by the
lug E being made to engage with the opposite lugs E by a reverse rotation of
bar E as aforesaid.
Further if it be desired to bodily remove the fire box D. from room to room
same can be effected by lifting it off the flange D' and placing it on any other
grate frame made according to my invention.
If necessary recesses can be formed in the grate for the insertion of handles
for the more efficient removal. I do not confine myself to the size or general
design or construction of my invention as it can be modified to suit its various
applications, nor to the actuating means which may be used for the release and
retention of the grate from, and in its fixed position for use, also I do not limit
myself to the exact manner in which the fire box may be attached to or detached
from the main central axial frame, but that as shown respectively, I consider to
be preferable and to give the best practical results.
Having new 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 fire box or grate for domestic purposes made, constructed and arranged so
that it will rotate either partially or wholly on an axis or pivot, substantially as
and for the purposes herein described and as illustrated in the accompanying
drawings.
2. A fire box or grate so formed that it can be easily attachable to and
detachable from its relatively permanent or fixed frame such as C. substantially as
and for the purposes herein described and as illustrated in the accompanying
drawings.

page_text: 3. A fire grate as herein specified and claimed, provided with means for release
and retention, substantially as herein described and as illustrated in the accom-
panying drawings.
