I, ALFRED WILLIAM MANTLE, of the Mount, Northfleet, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide certain improvements in the construction
and working of kitchen ranges viz.:
First: An arrangement for a door or flap connected by any suitable means to
scrapers or brushes.
This door or flap is constructed in such a manner that when the scrapers or brushes
are drawn forward for the purpose of cleaning the soot and other deposits of combustion
out from the flues a catch or fastening is released which causes the door or flap to open
in such a manner that an opening is made through which the soot and other deposits
may drop into a suitable receptacle placed beneath such opening to receive it and
further when the aforesaid scrapers are pushed back to their proper position this door
or flap is again closed up to its original place and properly fastened by the catches
provided for that purpose.
Secondly: In order to attain the greatest ease and efficiency in working the scrapers
or-brushes a pair of runners of equal size are fitted to the scraper frame on opposite
sides these runners being rigidly connected with each other by any suitable means
thereby causing the frame when being drawn forward to advance equally on each
side without jamming.
The scraper frame is fitted with loose scrapers which are attached and held in
position by screws or any suitable means and in such a manner that they can move
laterally and vertically in the flues the inequalities in the sides of the flues rendering
these movements necessary.
Thirdly To secure the best results from the products of combustion it is important
that the flames and gases should traverse as much of the oven and boiler surface
as is possible: to attain this object a boiler is constructed and placed in such a
manner that two of its sides and one side of its back forms a furnace or fire box
while the greater part of its bottom surface forms with the back part an outlet
flue..
The fuel is consumed in the furnace the flames and gases passing over the top of
the boiler and oven round the side and bottom to the side where the furnace is fitted
coming here into contact with the bottom of the boiler as before mentioned passing
thence up the back of the boiler into the flue or uptake.
Fourthly: The hot plates are made of cast iron, steel, or other suitable material and
the hot plate directly over the furnace is so made that by means of ribs and a
detachable plate it forms an effective smoke consumer and also diffuses the excess of
heat from that part of the range to parts farther removed from the direct action of
the fire.

page_text: I, ALFRED WILLIAM MANTLE, The Mount, Northfleet, Kent, 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:
The object of this invention is to provide improvements in the construction of
and working kitchen ranges, viz. :-
1st. A door or flap is connected by any suitable means to scrapers or brushes and
used in combination for the purpose of clearing the flues from soot and other deposits
of combustion and collecting the same into a suitable receptacle provided for that
purpose.
The door or flap is constructed in such a manner that when the scrapers or brushes
which traverse the flues from back to front are drawn forward a suitable fastening or
catch is released and causes the flap or door to open in such a manner that an
opening is made in the bottom or-other-suitable-part of the flue through which the
soot or deposit falls into a box or other receptacle placed beneath it for that
purpose.
The scrapers or brushes having traversed and cleaned the flues are now pushed
back into their proper position at the back of the range and the flap or door is also
brought back into its position by means of a weight spring or any other suitable
apparatus provided for that purpose.
2nd. In order to obtain the greatest ease and efficiency in working the scrapers or
brushes a framework is made which fits loosely into the various flues around at the
sides of and under the oven this framework being mounted on a pair of runners of
equal size rigidly fixed to a spindle and connected together thereby ensuring an equal
advance on each side without the risk of the scrapers becoming jammed in the flue
spaces. The scraper frame is fitted with loose plates which form the scrapers which
are attached to and held in position on the frame by screws or any other suitable
fastening these plates are so constructed that they may move both laterally or and
vertically respectively on their frames in the flues the inequalities in the plates and
flues rendering these movements necessary.
3rd. To secure the best results from the products of combustion it is important
that the flames or gases should traverse as much of the oven and boiler surfaces as is
possible and to attain this object a boiler is constructed and placed in such a manner
that two of its sides and one side of its back forms a furnace or fire-box while the
greater part of its bottom surface forms with its back an outlet flue.
The fuel is consumed in this furnace the flames and gases passing over the top of
the boiler and oven round the side and bottom to that side of the oven where the
furnace is fitted coming here into contact with the bottom of the boiler and
passing thence up the back of the boiler into the main flue or uptake.
4th. The hot plates are made of cast iron steel or other suitable material and the
hot plate directly over the furnace is constructed in two pieces a top plate fitted with
ribs running across it and a detachable plate screwed or rivetted to this in such a
manner that it forms an air chamber into which cold air is admitted through suitable
openings this air in passing between the two plates becomes highly heated and is
discharged directly over the point where the sinoke rises from the furnace to pass
over the boiler and oven and by this means an effective smoke consumer is provided
which also diffuses the excess of heat from this part of the hot plate to parts farther
removed from the direct action of the fire.

E loosely mounted side scraper plates, FFF boiler, G ribbed plate.
Having non 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. In kitchen ranges provided with scrapers or brushes and means for moving them
backwards and forwards, means for securing and working the soot door or flap so as
to discharge the soot to a receptacle beneath as hereinbefore described.
2. In kitchen ranges provided with scrapers or brushes and means for moving them
forward and backward and for discharging soot to a receptacle beneath in accordance
with the preceding claiming clause, mounting the frame upon rollers as hereinbefore
described and illustrated in the accompanying drawings.
8. In kitchen ranges provided with scrapers or brushes and means for moving them
forward and backward and for discharging soot to a receptacle beneath in accordance
with the preceding first claiming clause, connecting the scraper plates or brushes to the
frame so as to allow of their movement to prevent jamming substantially as hereinbefore
described and illustrated in the accompanying drawings.
