PROVISIONAL SPECIFICATION.
A Baker's Fire-box or Trolly.
WILLIAM BEGG 8 Olive Terrace Musey Road Sale Agent do hereby declare the
nature of this invention to be as follows:-
Instead of the plan hitherto used, of one pipe for trollies, I make this fire-box with
two pipes, and of iron, steel, or fire-lay, with a hollow chamber round it; which
chamber is solid at the bottom, with holes at the top to let out the heated air to
mix with the gases above the fire-box.
The air which supplies this chamber is taken in by an independent pipe and
separate from the one that supplies the fire.
Hence this trolly requires two air pipes to get a more complete combustion and
prevention of smoke.

COMPLETE SPECIFICATION.
A Baker's Fire-box or Trolly.
WILLIAM BEGG, 8 Olive Terrace Sale in the County of Chester, Agent, 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 construct a baker's fire-box or trolly with hollow
chambers, separate from the ash-box, so that the right amount of heated air may be
supplied above the fire to mix with products of combustion and to ignite them,
and by that ignition produce more heat, and prevent smoke, and to do this without
taking any air from the supply needed by the fire.
make the fire-box of steel or iron with fire-clay tiles to prevent chambers which
are round the box from burning through; the box has two pipes or a divided one
large enough to supply these chambers with air.
These chambers differ from all other trollies in use, in having a solid bottom and
holes at the top to let the heated air out to mix with the gases above the fire; at the
entrance of the chambers there is a door or valve to close the air passages to the
chambers when there are no carbon products to be consumed, so that then all the air
may pass through the fire from the ash-box.
That the invention may be clearly understood drawings of the box are hereto
annexed.
Fig. I is side elevation through middle.
Fig. 11 is the plan.
A Figs. I and II shows the chambers round the box for the conduction of the
heated air. In Fig. I the top of the box has been taken off the chambers in two
places to show the way the air takes, (marked by arrows) and the division of the
chambers.
C Figs. I and II shows the lire-clay tiles which prevent the box from being
burnt, and can easily be replaced.
B Fig. I is the door which closes the supply of air to the chambers (A) and can be
opened or closed at will by connecting a wire brought out to the end of the blow
pipe; the dotted line in Fig. I at B shows the movement of door.
D Fig. is a fire-clay grid on which the fire rests.
E Fig. I is the ash-box which supplies air to the fire.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is:
1. A fire-box with hollow chambers which are solid at the bottom, with an
independent air supply separate from ash-box, which have holes at the top to let out
the heated air above the fire; which also have fire-clay tiles to prevent the said
chambers from burning through, and the fire-box has a fire-clay grid for the fire to
rest upon.
2. The principle of two pipes or a large divided one to supply the air to the
chambers and to the fire.
3. A door or valve to close the air supply at will.
