Application April 8, 1937, Serial No; 135,784 4 Claims. (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. 35 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: ' Figure 1 is a view partly in elevation and partly in section of the apparatus embodying the pres ent invention showing the same applied to a Fig. 2 is a v1ew in top plan of the apparatus upon a’ reduced scale, a part of the top being broken away. Fig. 3 is a section taken on the line 3-—3 of vReferring now more particularly to the draw 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. . . 35 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! 2 V 2,122,314 the door and thus hold it in this raised position, 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 , outwardly and retracting the trip pin‘ l9. " ' 2. In a stove structure having a top provided with a fuel receiving opening, a casing adapted to be mounted upon said top and having a fuel discharge opening in registry .withsaid fuel re ceiving opening, means for intrbducingfuel into the' top of the casing, a partitioning door pivotal Jly. mounted Within the casing and adapted to be “oscillated to a fuel supporting partitioning posi The oscillatable shaft 23 to which the bar re-' _‘tion therein, a bar member extending vertically 10 taining hook 22 is attached, is provided with 'a lateral arm 24 to which may be attached one end of a cable 25. At any suitable point adjacent the fuel feeding apparatus an alarm clock mech-' anism, generally designated 26, is positioned. Any at one side of the casing and pivotally attached 10 at: its lower end to the casing, a trip pin pivotally attached to the bar member and extending through the adjacent casing wall at a point to . engage beneath said door to maintain the latter 15 ordinary alarm clock may be employed, and since ‘ in partitioning position, guide means for the such clocks are fairly well standardized in con upper end of the bar carried bythe adjacent struction, particularly with regard to the provi wall of the casing, resilient means arranged to sion ‘upon the back thereof of a winding key for normally urge the upper end of the bar to swing the time mechanism, as indicated at 21' and a outwardly, from the casing, a shaft oscillatably 20.L winding shaft 28 for the alarm: mechanism to supported upon the casing, a hook carried by the 201 which is threadably attached a key (not shown), shaft and adapted to engage‘ the upper end of the no detailed construction of this part of the mech-. bar to retain the same against movement by said anism will be shown other than to show the lo resilient means, and means for effecting the oscil-w cation of the timing mechanism winding key, lation of said shaft to disengage? the hook from’ 25‘iand alarm mechanism winding shaft. ‘ In carry ing out the present invention, the cable 25 is attached to a spool 29, one end of which is pro the bar. . 251i , 3. In a stove having a top provided with a fuel receiving opening, an elongated‘ vertically dis? vided with a screw 30 of suitable size to facilitate attachment of the same with the alarm winding . posed casing adapted to be mounted upon the top of the stove and having a downwardly open 39llshaft 28 of the clock. ing outlet designed to register with said fuel in 39-5 In placing the apparatus in operation, the par; let, means for introducing fuel into the top end titioning door 9 is raised to horizontal position in ' of the casing, a fuel supporting partitioning door the casing 4' and a charge of fuel is placed ‘in the oscillatably mounted within the casing and casing upon the door. The .door will be held in adapted when in partitioning position’ to sup 35‘rraised position by the trip pin 19 with the rod l4 po-rt a ‘charge of fuel, a bar member disposed retained against movement by the hook 22. The vertically on one side of the casing, pivotal means alarm apparatus of the clock 26 after being ‘wound in the usual manner by rotating‘ the screw 30, between the lower end of the, bar member and will be set to go off or release at a time when it 40.,is known that the brooder stove will'require re ”charging with fuel and the cable 25 will be wound up on the spool 29. until it is tight so that a fur ther winding up such as will occur’ when the alarm goes off and the shaft 28 rotates" in the 45 usual manner, will oscillate the shaft 23, raise the hook 22 ‘and release the bar M. This will permit the casing, a guide pin secured at one end of" the casing and extending outwardly through an aperture in the bar member, a pin pivotally at; tached at one end to the bar in the plane of the 49., pivot, for the partitioning ‘door, vsaid pin being adapted to extend through’ an- adjacent casing wall opening to engage beneath and support the door in partitioning position, a spring member 45,1: the spring 2| to force the bar outwardly and interposed between the bar‘and the casing and retract the trip pin l9 thus allowing the fuel normally urging the bar toxoscillate outwardly, charge to drop downwardly through the top of I a hook member pivotally attached to the casing 59 and into the brooder stove. and adapted toqengage and‘ hold said bar mem In order that fuel may be conveniently put into ber against movement by‘ said spring and ‘means the brooder stove directly as may be necessary, for shifting said hook member to bar releasing a wall of the casing 4 below the door 9 is provided position at a predetermined time.
