BROODER STOVE.

l cationfiled October 1, 1926, Serial No. 138,994. I

' The invention relates to improvements in heaters designed primarily for .poultry breeders, and my principal aim is toprovide a unique constructionand relation Otdampers for attaining the desired ends, provision being made whereby upon heating of the stove to a predetermined extent, the draught thereto will be cut oil, one damper plate. will be substantially closed across the smoke outlet,'another damper plate will be opened to admit air into the smoke outlet, and openings in the first named'damper plate willbe exposed,so that some of the air enter-. ing said smoke passage, may descend to cool the 'fire,while the'remaining air entering the smoke passage, may ascend to produce effective ventilation of the brooder stove and house.

.With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, the descriptionbeing supplemented by the accompanying drawings.

Figures 1 and 2 are side elevations partly broken away and in section, looking in different directions, the hover being omitted from these views.

' Fig, 3 is a vertical sectional view taken substantially on line 3.3 of 1;

.Fig. is a horizontal section on line 1 /1 of Fig. 2;

' Fjg. '5 is a small side elevation of the stove with the hover connected therewith,the latterbeing shown in section.

- Inthe drawings above briefly described, 6 designates the baseof the-stove, supporting the ashpit 7 from which. the substantiallycylindrical body 8 rises, said body having a fuel inlet door 9 atany suitable point, preferably near its upper end andbeing provided with an appropriate grate 10, Any desired provisionmayof course be made for shaking this grate. ll designates a doo'rfor removing ashes from the ashpit Z, and it will be understood that the bottomfof thisfashpit is spaced above the brooder floor by the based, so thatthere is no danger of fire. Moreover, this base is formed with openings 12 which permit passage of air under the ashpit, keeping the same comparatively cool.

The stove is provided with two downdraught passages 13 whose lower ends open under the grate 10. The upper ends of these passages are controlled by two dampers 14 carried by the outer end of a pair of levers 15, these levers being suitably mounted at 16 upon the upper end of the stove. An operating'rod 17 is appropriately connected with the inner ends of the levers 15 and is automatically operated by means hereinafter described, to control the draught to the fire. 18 designates a preferably rectangular smoke outlet member which is appropriately mounted uponthe stove body 8, the upper end of this member 18 being preferably provided with a collar or the like to connect with an ordinary smoke pipe 20, leading to any remote point outside of the brooder. The member 18 is formed with an air inlet opening 21, and within this member, near the opening, are two damper plates 22 and 23.

The plate22 is impertorate and is pivoted on a horizontal axis 2 1 about one inch below the lower edge of the opening 21, said plate when in the dotted line position of Fig. 3 serving to close the opening 21 against entrance of air. The reason I pivot this damper plate v22 below the lower edge of opening 21 is to form a'pocket to catch any sparks that may come down the chimney, thus preventing danger of fire.

An arm 25 is secured to and projects outwardlytrom the damper plate 22, said arm being pivoted to the upper end of a rod 26 which is operatively associated at its lower end with an appropriate thermostat 27 suitably secured to the stove. It desired, any

suitable provision (not shown) may bemade for extending or retracting the length of the rod 26 to control the automatic operation of the damper plate 22, under the influence of thethermostat 27. I

A second arm 28 projects outwardly'from the damper-plate 22 and is pivoted to the upper end of the rod 17 By this provision, when the thermostat 27 expands under redeter nined heat and moves the damper p ate 22 inwardly to admit air through the opening 21, the arm 28 pulls upwardly upon the rod17, thus actuating the two levers 15 to close the dampers 14;, thereby cutting off the draught to the fire. Similarly, when the thermostat contracts" and the damper plate 22 is consequently moved to or toward the dotted line position of Fig. 3, the arm 28 and rod 17 cause such movement of the levers 15, as to again open the draught controlling dampers 14. i

The damper plate 23 hangs vertically in 'the'd'otted line position of Fig. 3, when the plate 22 is closed, said plate 23 being then positioned at the inner side of said plate 22. The pivotal mounting Q9 of plate 23 is above the upper end at the plate 22 and also above the opening and it will be observed also from Fig. 3 that above said plate 22, the plate :23 is formed with a relatively large opening- 30, while it is formed with a smaller opening 3 below the upper end of plate The movements imparted to the plate 22 by the thermostat 27, control the movements of the plate 23, and as said plate 22 is moved inwardly to the full line position of Fig. 1- it swings the plate 23 to an oblique position across the smoke outlet member 18. \Vhen this position is reached, both openings 30 and 31 are exposed. Thus, the air entering through the opening 21 may pass through the opening- 230 and while some of this air may descend through the opening 31 to cool the tire, the remainder of such air will pass upwardly through the smoke outlet, thus carrying ofi all foul air from the breeder stove.

An appropriate supporting ledge 32 is provided. near the upper end of the body 8 for the purpose of supporting a sheet metal hover 33, said, hover declining outwardly from the upper end of the stove to a plane spaced a desired distance above the hrooder floor. Under this hover, the stove is provided with an air heating drum 34 which extends around a portion of its circumference, said drum having an inlet 35 at its lower end for fresh air from any desired source. The upper end of the drum 34 however, is open so that the fresh air which enters through the inlet 35 and is warmed in the drum 34, will be discharged under the hover and will conserpiently be downwardly directed onto the chicks.

Any appropriate mechanical details may be utilized in the manufacture of the heater. For instance, some parts may he made of castings or sheet metal, some parts may be either integral with others or formed separately. sectional construction may be used whenever advantagreons. and parts may he secured by riveting, welding. bolting or in any desired manner. such details being left to the .manutacturer for selection. Moreover, it may be explained that provision may be made permitting raising and lowering of the hover 33 ii" desired. Here again, any adequate mechanical provision may be made for the purpose.

Excellent results are obtainable from the general construction shown and described and such construction may therefore be followed. llowever. within the scope of the invention as claimed, variations may of course be made.

I claim:

1. In combination with a substantially vertical smoke outlet passage having an air,

inlet opening in one vertical. side; a damper plate pivoted in said passage on a. horizontal axis spared below said opening and in parallel relation with said one side, said damper plate in one position being; :nlapted to close said o iening, a second damper plate pivotally hung in said passage upon an axis spaced above said opening and the upper end of the first named damper plate, said second plate contacting with the inner side of said first named plate to be swung by the latter to an oblique position across the passage. said second plate having an opening in its lower end and an opening in its upper end above said air inlet opening, said lower and upper openings being: ex 'iosed when said second damper plate is in said oblique position, and operating means connected to the first named damper plate.

2. In con'ibination with a smoke outlet passage having an air inlet opening in one side; a damper plate pivoted in said passage on a transverse axis at one side of said opening, said damper plate in one position serving to close said opening, a second damper plate pivotally mounted in said passage upon a transverse axis near the opposite side of the openin said second damper plate contacting with the inner side of the first named damper plate to be swung by the latter to an oblique position across the passage, said second plate having an opening in its free end and a second opening in its pivoted end, both of these openings being exposed when said second damper plate is in said oblique position, at which time these openings are disposed at opposite sides of the contacting portion of the first named damper plate, bot-h openings of the second damper plate being closed by the first named plate and the aforesaid side of the smoke passage when said plates lie parallel with said side, and operating means connected to said first named damper plate.

In testimony whereof I have hereunto aflixed my signature.

JOSEPH B. SMITH.
