IMPROVE- MENTS IN APPARATUS FOR SUPPLYING STEAM BOILER AND OTHER FURNACES WITH FUEL to be as follows:
Year: 1885

page_text: I JAMES PROCTOR of Hammerton Street Iron Works Burnley in the County of
Lancaster Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR SUPPLYING STEAM BOILER AND OTHER FURNACES WITH
FUEL to be as follows:-
"
This invention relates to improvements upon the construction of the "mechanical
stoker" for which Letters Patent were granted to me bearing date the 18th day of
November A.D. 1880. N° 4759. the object of the present invention being to simplify
the construction and to improve the action of the ram d, d as described in the
Specification of the Patent above referred to.
I propose to dispense with the lever g, g and the excentric h, h (see Fig. 4. of
the drawings annexed to the said Specification) and I move the worm wheel shaft,
bevil gearing, and lantern wheel w, w with the tappet levers x, x towards the left
hand until the worn wheel shaft is at or about the central position formerly occupied
by the lever g, I.
In gear with the bevil teeth on the lantern wheel I mount a bevil pinion upon a
horizontal axis at right angles. to the front plate. On this axis is also keyed a face
plate provided with a crank pin which works in a slot in a lever hung from a
pin above.
This pin passes through the front plate into the feed box and has attached to it
a similar lever the lower end of which works in a slot in the upper side of the
ram, to which the revolution of the crank pin thus communicates a reciprocating
motion.
t
In cases where the movable fire bars are not required the action is much more
simple.
The short shaft which carries the lantern wheel is driven by spur gearing (instead
of bevil gear) the bevil wheels and worm wheel shaft being dispensed with, and
upon the driving shaft I mount a grooved cam which acts direct upon the ram
lever (instead of the face plate and crank pin above described) and at one end of
this shaft is keyed a spur wheel gearing into a spur pinion fixed to the boss of the
grooved driving pulley which is mounted loose upon a stud, and at the other end
is a spur pinion gearing into. the spur wheel cast upon the side of the lantern wheel
which actuates the shovels as before.

I JAMES PROCTOR of Hammerton Street Iron Works Burnley in the County of
Lancaster Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR SUPPLYING STEAM BOILER AND OTHER FURNACES WITH
FUEL" and in what manner the same is to be performed, to be particularly described.
and ascertained in and by the following statement :-
This invention relates to improvements upon the construction of the "mechanical
stoker" for which Letters Patent were granted to me bearing date the 18th day of
November in the year of our Lord 1880, N° 4759 the object of the present
invention being to simplify the construction and to improve the action of the
ram d. d as described in the Specification of the Patent above referred to.
The construction of the apparatus will be readily understood on reference to the
annexed sheet of drawings and the following explanation thereof :-
Fig. 1 on the annexed drawing represents a vertical section of my improved
arrangement of "mechanical stoker" when movable fire-bars are employed and
Fig. 2 is a front elevation of the same.
Figs. 3, 4 and 5 are detached views (hereinafter more particularly referred to).
showing the modification which I propose to employ when no movable fire bars
are required.
According to my improved arrangement I propose to dispense with the lever g,g,
and the excentric h, h, (see Fig. 4 of the drawings annexed to the said prior
specification No 475980) and I move the worm-wheel shaft (marked h¹, h¹, on the
present drawings) bevil gearing h¹, h, and lantern wheel w, w, with the tappet
levers x, x, towards the left hand as shown at Fig. 2 until the worm-wheel
shaft h, h, is at or about the central position formerly occupied by the lever g, g.
In gear with the bevil teeth on the back of the lantern wheel I mount an
additional bevil pinion i, i, keyed upon a horizontal axis k, k at right angles to
the front plate of the boiler-On this axis k, k, is also fixed a face plate 1, 1,
provided with a crank pin n, n, which works in a slot in a lever o, o, hung from a
spindle p, above.
This spindle p, passes through into the feed box a, a, and has attached to it a
similar lever q, q, which works in a slot in the upper side of the rain d, d, (as
shown at Fig. 1) to which the revolution of the crank-pin n, n, thus communicates
a reciprocating motion.
The movable fire-bars may be actuated either from the lower end of the worm-
wheel-shaft h, h, or from the driving shaft 1, 1, as in my former Patent above
referred to.
In cases where the movable fire-bars are not required the action is much more
simple and is illustrated in front elevation at fig. 3.
The short shaft r, r, which carries the lantern wheel w, w, is driven by spur
gearing (instead of bevil gear) the bevil wheels and worm-wheel-shaft being
dispensed with -A side view of this spur gearing is shown detached at Fig. 4.

page_text: Upon the driving shaft t, t, I mount a grooved cam u, u, which acts direct upon
the ram lever o, o, (instead of the face plate l, l, and crank pin n, n, above described)
and at one end of this shaft t, t, is keyed a spur wheel 2, 2, which by means of a
carrier wheel 3, 3, (see detached side view Fig. 5) gears with a spur pinion 4, 4,
fixed upon the boss of the grooved driving pulley 5, 5, (which is mounted loosely
upon a stud) and at the other end of the shaft t, t, is a spur pinion 6, 6, gearing
into a spur wheel 7, 7, cast upon the back of the lantern wheel w, w, in place of
the bevil teeth,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what-
I claim is
First in a "
mechanical stoker" of the class herein before referred to having
movable fire-bars the improved mechanism for actuating the ram, consisting of the
bevil pinion i, i, horizontal axis k, k, face plate l, l, crank pin n, n, spindle p, p,
and lever q, q
Secondly in a "mechanical stoker" of the class herein before referred to (not
provided with movable fire bars) the improved mechanism for driving the lantern
wheel, consisting of the driving shaft t, t, and spur wheels and pinions 2, 3, 4, 5, 6,
and 7 all being constructed, arranged and operating substantially as hereinbefore
more particularly described and illustrated by the drawings annexed.
