I JOSEPH GOODMAN of No 296 Rolls Road, Bermondsey in the County of Surrey
Mechanician do hereby declare the nature of my Invention for FIRE FEEDER to bo
as follows:
The object of this invention is to feed a fire at the bottom or lower part of a fire
place by means of a simple mechanical arrangement attached thereto and whereby
so introducing the Coal, the smoke and Gas given off are consumed in passing
through the upper part of the fire.
My invention consists in a Cylinder or Cylinderical shell having an opening
through one side thereof and around the outside edge of which is slightly raised
forming a suitable nozzle through which the Coals pass into the fire on the
inside of the Cylinder at each end are provided with a Disc having a rim on
the outside edge and which are made to rotate the Cylinder forming the bearing in
which they turn.
The inside edge of the Disc's are placed flush with the extent of the said
opening in the Cylinder and between the said Disc's are arranged side by side
a set of Cams or combined Cambars extending from Disc to Disc and having a
clear working space between each and are connected together along the centre
only, the centre thus forming an axle each end of which joins the centre of each
Disc and is firmly connected thereto, the form of the said Cams are bent arms
starting from the axle and at right angles thereto and having a Camber on the
front, the line of Camber intersecting the diameter line of the axle and extends to
the Cylinder from which point they run in a backward direction following the
regular circle of the Cylinder with sufficient working clearance and as slight as
possible consistent with strength required and which forms about of a circle and
are tapering to the end.
On the inside edge of the said opening in the Cylinder the side towards which the
said Cams rotate are arranged side by side a set of stationary bars which having a
Cambar on the front extend to the axle between each Cam the axle being slightly
grooved to form a guide and bearing for the ends thereof opposite or facing the
said bars a set off is made in the Cylinder commencing gradually and extend to
the said opening therein with a gradual increasing distance from the bars, between
D •

fed the Coal passing into the cavity formed therein between axle Disc's and behind
the bars the said opening in the Disc's is about opposite the points of the Cams in
taking a straight line therefrom across the axle.-The normal position of the
Cams is when the points thereof have just entered between the said bars, and from
which position they are made to rotate by means of a jointed hand lever attached
to the same Disc and when operated the Cams are brought directly on to the Coal
which is thus impelled forward against the said bars where they are ejected from
between both and are thus raised to the highest points of the Cams and thus into
the said opening through the nozzle and into the fire, the extensions of the Cams
retaining them so until the next charge is operated in the same way when in
regular course the said extensions withdrawing therefrom allows the next following
charge to take their place in succession.
The nozzle part of the apparatus is fitted to the bottom or lower part of a fire
place and fixed at any angle varying from an horizontle to a verticle line and may
be supplied with fuel at one or both ends where by means of an Hopper attached
thereto a constant supply can be obtained in case the larger size apparatus should
require more power to operate it. I may prefer to employ a tooth wheel and
pinion for that purpose instead of the said lever.
It may be seen that this apparatus can be easily fitted to any ordinary fire place
and also that Coke may be used as the fuel, and that the upper part of the fire
always offers the most heat which is so essential for many purposes more especially
for generating steem.

I, JOSEPH GOODMAN, of 296 Rolls Road, Bermondsey, Surrey, do hereby
declare the nature of my said 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 feed fires at the bottom or lower part, of the
fireplace or furnace by means of simple mechanical arrangements attached thereto;
the introduction of fresh coal by such means causing the smoke and gases evolved
therefrom to be consumed in passing through the incandescent coals above the
same.
And in order that my said Invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a front view of my Invention. Fig. 2 shews the same with the front
plate removed. Fig. 3 is a top view, partly in section. Fig. 4 is a view of one of
the cam bars, and Fig. 5 is a view of one of the intermediate stationary bars.
My invention consists of a cylinder or cylindrical shell a a having an opening b
through the upper side thereof, the outside edge of which is slightly raised at co
so as to form a suitable nozzle, through which the coals rise as they pass into
the fire.
Discs & and dare fitted in the cylinder, one at each end having a rim on the
outside edge, and which are made to rotate in the cylinder, thus forming the
bearings in which they turn. The inside edges of the discs are placed flush with
the extent of the opening in the cylinder, and between the discs are arranged
alternately a set of stationary bars f and movable cams or combined cam bars e e.
The stationary bars ff provide clear working spaces between each of the bars e e,
which are connected together along the centre only. The centre thus forms an
axle one of each of the ends of which joins the centre of one of the discs and is
firmly connected therewith; the form of the movable cams e e are clearly shewn
in Figs. 2 and 4, in which it will be seen that the working edge is cambered as
shewn at el. At the point e the form follows the regular circle of the cylinder,
with sufficient working clearance, and the cam bars are made as slight as possible,
consistent with the strength required, and their length extends to about two thirds
of a circle, tapering towards the end. On the edge of the opening in the cylinder
the upper ends of the stationary bars ƒ ƒ are fitted to the beam k, or cast in
one therewith, as preferred. These bars are cambered on the edge f¹, as shewn.
The lower ends f³ of these stationary bars are supported by the axle, which is
slightly grooved to form a guide and bearing for that purpose. On the opposite
side of the opening at c, the wall of the opening is formed as shewn in Fig. 2 with
a gradually increasing distance or clearance.

an entire circle. The edges e¹ of the moveable cam bars then raise the coal and
force it under the incandescent coals.
The two end bars f³ are made to encircle the axle at each end.
It will thus be seen that by means of the jointed hand lever or handle h, or
equivalent means attached to the front disc the cams are brought directly on to the
coal, which is thus carried forward against the said bars where they are ejected
from between both and are thus raised to the highest point of the cams, and up the
said opening, through the nozzle, and into the fire; the extensions of the cams
retaining the coals in such position until the next charge is made in the same
manner. The apparatus may be fitted to the bottom or lower part of any kind of
fireplace, and fixed at any angle varying from a horizontal to a vertical line, and
may be supplied with fuel at one or both ends, where by means of a hopper
attached thereto a constant supply can be obtained. In case the larger sizes of the
apparatus should require more power to operate them, I prefer to employ a toothed
wheel and pinion for the purpose instead of the lever h
It is obvious that this apparatus may be fitted to any ordinary fireplace steam
boiler, or other furnace, and also that it may be used with coke, coal, or any other
fuel, and that.by my invention the upper part of the fire is made to afford the
greatest amount of heat, which is essential for many purposes, more especially for
generating steam.
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
The manufacture and use of improved apparatus for feeding furnaces, domestic
and other fires, whereby the fuel is more thoroughly utilised, constructed arranged
and operating substantially as and for the purposes herein before described and
shewn on the drawings.
