PROVISIONAL SPECIFICATION.
Improvements in Automatic Firing Appliances for Furnaces and
the like.
I ABEL MAYER of 23 Birch Terrace Hanley in the County of Stafford
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
Rollers, with grooves on opposite sides of them, revolving on axes fitted in
frames or boxes, are placed over a furnace or other fire; if desired, in connection
with corresponding slots in the brickwork or other substance forming the roof of
the furnace. Above the frames or boxes is fixed a tank holding the slack or other
fuel, which drops through slides or apertures in the tank into the grooves of the
rollers. To the rollers is given a rocking or revolving motion, causing the empty
grooves to be filled from the tank at the precise moment that the full ones are
discharging their contents over the fire.

ABEL MAYER of 23 Birch Terrace Hanley in the County of Stafford
Mechanical 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 invention consists of an iron box or frame placed over a furnace in which
is placed a cast iron cylinder supported in each end of the box or frame and
moving freely in same; the cylinder having slots or grooves through it in a
triangular form running the whole length of cylinder and communicating with
each other. When at rest the upper opening is always open into the box con-
taining the fuel whilst the other openings are closed by coming in contact with the
sides of the box or frame. If a rocking motion be given to the cylinder the lower
openings will be alternately turned to the bottom or low enough to discharge their
contents and to open communication with the upper groove, thus giving free access
to the fuel in the box or hopper to fall through the slot or groove upon the fire
underneath. It will be seen that two boxes may sometimes be required for large
furnaces.
Referring to the annexed drawings,
Fig. 1 is a sectional view of box or frame (a) with cylinder (b) showing grooves
or slots (c) in position for delivering slack or other fuel through its bottom opening
on the fire.
Fig. 2 is an end elevation showing box or hopper (d) containing fuel, and box
or frame (a) containing cylinder (6) with arm (e) for giving motion to same.
Fig. 3 is a plan of box or frame (a) containing two cylinders (bb) with their
bearings in frame (ff) showing position of grooves or slots (9 g) at rest or in
operation with provisions for arms or levers (ee) for giving motion to same.
Fig. 4 is a side elevation of box or hopper (d) containing the slack or fuel with
frame or box (a) containing cylinder (6) with end bearings (ff) and arms or
levers (ee).
is a side view of furnace; is an end view of same.

page_text: Having now particularly described: and ascertained the nature of my said inven-
tion and in what manner the same is performed 'I wish it to be understood that I
do not intend to limit myself to the details and I declare that what I claim as my
improvements in automatic.firing appliance for furnaces and the like is :-
1. A saving in fuel is effected by firing with the said appliance as slack may be
used instead of coals.
2. 'Better combustion is obtained when firing with the appliance as the 'fuel is
equally distributed over the fire in small quantities.
3. A saving is also effected when firing with the appliance as the temperature of
the furnace is retained there being no necessity for having the -stoke *hole 'open
when firing and allow cold air to rush into the furnace as is the case when firing
by hand.
