FUEL SUPPLYING MEANS FOR BROODER

(01. 110-5118) _
a stove, 'in addition to being provided with the
animal husbandry and particularly to brooder smoke outlet 2, has its top provided with a fuel
supplyingopening 3 which is normally closed by
heaters.
'
'
For certain types of brooder heater structures, a cover or'plate (not shown).
‘ This invention relates generally to the class of
5 stoves are employed which burn solid fuel such as
coal or the like, and in severe weather this fuel
frequently gives out during the night thus making
it necessary for the operator to attend to the same
during the night or else allowing the brooder to
10 ‘become cold.
~
-
The present invention has for its primary ob
ject to provide a self-?ring or feeding apparatus
designed for attachment to a solid fuel burning
stove used in association with brooder structures
15 so that at a predetermined time a new charge of
fuel can be added to the brooder stove without
requiring the attention of an attendant.
Another object of the invention is to provide a
self-?ring device for a brooder stove which, in
20 ‘addition to being so constructed as to carry a
charge of fuel to be delivered into the stove at a
predetermined time, is constructed to permit the
feeding of fuel to the stove by an attendant with-
out necessitating the removal of the device from
the stove.
25
‘
A further object of the invention is to provide
a fuel charge, supplying means for a brooder or
other type of stove, which is constructed in a
novel manner to facilitate the use in association
3(‘,iytherewith of a timing device such as an alarm
clock or the like, so that when the clock is set to
go off at a predetermined time, it will auto
matically trip a release mechanism which will
permit the charge of fuel to descend into the stove.

The invention will be best understood from a
consideration of the following detailed descrip
tion taken in connection with the accompanying
drawing forming part of this speci?cation, with
the understanding, however, that the invention
o'fiis not con?ned to any strict conformity with the
showing of the drawing but may be changed or
modi?ed so long as such changes or modi?cations
mark no material departure from the salient fea
tures of the invention as expressed in the ap
4gilpended claims.
In the drawing:

ing, the numeral I generally designates the top
portion of a stove of the type employed in asso
ciation with brooders and designed to burn solid
m-gfuel such as coal, coke, corncobs, or the like. Such
‘The apparatus constituting the present inven
tion comprises a relatively long housing 4, which
is vertically disposed and which has its top end
covered by the removable lid 5, while at its lower
end it is tapered, as indicated at 6, to a discharge
outlet ‘I which is of the proper size and contour 10
to ?t over the fuel opening 3 in the top- of the
stove. .Suitable securing brackets 8 are pro
vided for ?rmly attaching the lower end of the
casing to the top of the stove so that fuel dis
charged through the casing will enter the hopper 15~
like constricted lower end thereof and pass di
rectly into the fire pot of the stove.
In the upper part of the casing 4 is pivotally
mounted a' partitioning door 9 which is designed
to support fuel until released to allow the fuel to 20
discharge downwardlyinto the stove. This fuel
supporting door has a‘shaft extending’ outwardly
‘ from the pivot pin or shaft by which it is attached
to one wall of the casing, as indicated at Ill, and
one end,v of this extended shaft I8 is turned later 26
ally to form the arm ‘I I from which is suspended a‘
weight l2. The shaft It may constitute an inte
gral continuation of the pivot rod for the door
and it. will thus’ be seen that since the shaft I0 is
?rmly attached to the door the weight l2 will 30
normally tend to oscillate the doortoclosed posi
tion, by which is meant a position where it will
extend across the casing 4 and thus close off the
upper part from the lower part which leads into
the stove.
.

One‘ of the walls of the casing 4 which is ad
jacent a free edge of the partitioning door 9, has
oscillatably attached thereto at the lower part
thereof, as indicated at l3, one end of an upward
ly extending rod Hi. This rod near its upper end 40
has an aperture l5 formed therethrough, through
which extends the guide pin it which is secured
at one end to the adjacent wall of the casing and
has a nut ll threaded upon its outer end to. limit
the outward movement of the upper end of the
bar M.
The. wall of the casing adjacent to the bar M
has ‘provided at an elevation corresponding with
the underside of the door 9 when the latter is in I
raised or closed position, an aperture l8 formed 50
therethrough'to receive the free end of a trip pin
H! which has its other end secured, as indicated
at 20, to the bar Ill. Surrounding the trip- pin
I9v and interposed between the bar M and the
adjacent wall of the casing is an expansion coil 55
spring 2! which normally exerts an outward pres-'
sure against the bar l4 thus tending to withdraw
the pin l9 from the opening I8. When the door
9 is in raised or horizontal position, the trip pin
I9 may be extended inwardly to engage beneath!

and when the pin is so placed it is maintained
against the tension of the spring 2| by the release
hook 22 which is carried by the shaft 23 which is
5 oscillatably mounted upon the casing abovev the
?xed bar I6. This hook 22 engages over the top
end of the bar l4 and thus holds it from swingin ,
