page_text: I, BENJAMIN COCKSHUTT FRYER of Napier, Hawkes Bay in the Colony of New
Zealand Ironmonger 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 Improvements in Fire Grates and is applicable to rooms
that adjoin one another my apparatus being so arranged that of two adjoining
rooms either room can be heated by the fire grate at the will of the occupant or
both rooms can be heated at one and the same time whilst a complete division of the
rooms is maintained; and further a fire can be lighted in one room and used in the
adjoining room by simply revolving the grate.
In order that that the said invention may be more easily understood I will now
proceed to describe the same and for that purpose shall refer to the several figures on
the sheet of drawings "left with the provisional specification" the same letters of
reference indicating corresponding parts in all the figures.
Fig. 1 is a front elevation of the Improved fire grate.
Fig. 2 is a section taken along the line, 1, 2.
Fig. 3 is a section taken along the line 3, 4.
A. is a circnlar grate or Fire basket divided into two parts by a division of fire
brick or other material B B, fitted into the cheeks C. C. D is the chimney or flue
containing the register M and common to both rooms E and F. G is a cast iron
frame fastened by preference to the outside casting or upright framing or to the
brickwork if brickwork be used between the two rooms E and F and is fitted with
rollers or ball rollers H H H H on which the grate is free to revolve the grate being
also further steadied by the centre pin or pivot I and the outer framing or casing Q. Q.
K. K. are plates or shutters free to move on the pin or hinge Land so placed that
they fall down upon the fire brick division Band secured by the catch P preventing the
passage of air, smoke, and communication between the rooms and capable of being
lifted up by the fire brick division when it revolves but falling down again upon the
said division when in its place and at rest. M is a register damper resting freely in
shoe at the foot and guided by guides N N at the upper end which relieves the foot
of part of the weight and causes the register to be easily moved from side to side of
the chimney D. by this means it can be placed in the position shown by the dotted
ines so as to adapt itself for a single chimney for either room or if desired be placed
vertically so as to cause a draught from both sides of the grate to heat both of the
ooms simultaneously.
It is evident that the form of the fire basket and outside casting can be varied and
ther equivalent devices can be used and the details of the subordinate mechanical
rrangements may be modified without affecting the principle of the invention.

page_text: Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I wish it to be understood that I
am aware of Marten's patent. No. 43 dated 3rd January 1887 and do not claim
anything therein contained but what I do claim is
The improvements in fire grates consisting of the combination with a revolving
grate or basket with a double front suitable for one or two rooms of plates or shutters,
flue and register as hereinbefore described and illustrated.
