This invention relates to brooder stoves and particularly to brooder stoveshaving a detachable hover which is shiftable sofas to raise the hover or lower the hover under certain changes and conditions. n The general object of the inventionis to improve certain details disclosed in pending application-Serial No. 193,836, filed on the 24th day of. May, 1927, issued June 18, 13 1929, as Patent No. 1,717,851. 8 r

In that application I have shown a brooder stove which includes an ash pit, a combustion chamber,'a magazine, and a smoke flue, the

flue having a check draft damper and ther mostat-ic means for coordinately controlling the action of the two dampers. v

More specifically, one of the objects of the present invention is to'provide' a water chamberexterior to the magazine and between the "ends of which the smoke flue passes, whereby to provide a means for supporting the hover in a vertically shiftable position and the water acting to retain a more uniform tem- 'perature within the brooder room and furn1sh moisture to the air in the brooder room,

this water chamber further acting to restrain the dry heat ordinarilyescaping from the magazine walls.

Another object is to so construct the stove that a space is left between the top of the combustion chamber and the lower end of the water chamber whereby the heat from the v upon the water chamber surrounding the magazine. p,

Other-objects will appear in the course of the following description. r My invention is illustrated in the accompanying drawings wherein 1 Figure 1 is' a vertical sectional view through a brooder stove constructed in ac cordance with my invention;

water chamber of the brooder stove showing the connection of a drinking pan.

Referring to Fig. 1, itwill'be seen that the stove comprises the ash pit "10, the combustion chamber section 11, the grate 12, the supporting brackets 13'therefor, 'an'upper section 14 for the combustion chamber, a lower 'magazine section 15 forming part of or carried by the section 14, and an upper magazine section 16 which carries upon it the water chamber 17 which is concentric to the section The section 11 is supported'uponthetop ported upon the top of the section 11.- The "section 16' is supportedupon the upper end of the lower wall section 15 of the magazine. The ash pit is providedwiththe air inletopening 18 and the upper end of :the' magazine is normally-closed by a cover 19.v The water jacket or chamber17 has a filling opening provided with a cover20.

As Wlll be seen from Fig. 2, the magazine of the section 10 .and the section 14: is sup is circular in cross section and surrounding the magazine is the water chamber 17. This extends nearly aroundthe magazine but terminates in the vertical end walls 21 defining a smoke flue 22. This smoke flue extends down to the lower end of the magazine section 15 and this magazine section carries upon it the circularly extending baflie wall 23. i The walls 21 terminate in spaced relation'to this battle wall so that an opening 24 is left through which ,theproducts of combustion passing upward fromthe combustion chamher 11 may pass through tothe smoke chamber 22'. The upperend'of the smoke flues isprovided with a nipple 2 5for theattach ment of a smoke pipe.

' The front wall of the smoke flue isconstituted by a removable plate 26 and by a wall 27 formed integral with the section 15 of the magazine and extending upward from the outer wall 11. The removable wall 26 has an aperture 26 at its upper end on the inside of which is mounted a check draft damper 28. This check draft damper is detachably mounted upon pivots at its upper end upon the upper end of the inside face of the wall 26 and has an outwardly projecting arm 29 to which the wire or rod 30 is connected.

The draft damper 31, pivoted at 32 by means of a plate 38, is attached to the wall of the ash pit 10 and is provided with an outwardly projecting eye to which the lower end of the rod 30 is connected by a hook. This rod 30 is connected to a thermostat as will be later stated.

The outer face of the outer wall of the water chamber 17 is formed with a plural ity of steps or ledges 34. It will be seen that the stove including this water chamber is preferably tapered upward.

The hover 35 is annular in form and provided with a ring 36, and the hover is preferably of sheet iron and its riveted or otherwise attached to this ring and the hover is preferably provided with a ventilator opening 37 having a damper 88. Adapted to fit upon the several steps 34, except the lower step of the series which is of sufficiently large diameter to engage with thering 36, is a ring 39 which is cut away at 40 so as to fit over the front wall 26 and is cut away at 41 to permit the passage of the wire or rod 30. The underface of this ring 39 is provided with the lugs ,42 constituting brackets, as it were. lVhen the hover is in its lowest position, it rests upon the flange 423 at the base of the water chamber 17. I If it is desired to elevate the hover, one of the rings 39 is placed upon the proper step 34 and the ring 36 forming an inner margin of the hover is engaged with this ring 39.' r

It will be seen from Fig. 5, that the water chamber may be provided at its upper and lower ends with the outwardly extending circulating pipes lei which may lead to a water heater whereby the drinking water for the chicks may be warmed. Any number of these drinking water heaters may be connected up with the water chamber 17.

lVith the construction which has been illustrated, the water jacket surrounding the magazine serves a three-fold purpose. Its outer surface provides a very simple means for supporting the hover in vertically adjustedposition. The heated Water within the water jacket or chamber 17 derives its heat from contact with the magazine walls and serves to secure or maintain a more uniform temperature in the brooder than is otherwise possible as it will remain hot for a considerable time after becoming heated.

Furthermore, the slight amount of steam or vapor generated by this water heater, furnishes moisture to the air in the brooder, thus preventing this air from becoming too dry. This secures for the chicks a soft moist heat instead of a dry harsh heat. The water within the water chamber becomes heated to the proper degree a short time after the stove is fired. N

Then the hover 35 is at its lowest posi tion, the water jacket or water chamber 17 serves to restrain the dry heat otherwise escaping from the magazine walls. Under normal circumstances, the fuel within the magazine will tend to back-fire or heat up. Considerable heat will be radiated outward from the walls of the magazine. This heat is modified therefore by the water contained within the water chamber 17. At the same time a certain amount of heat is radiated from the space between the upper wall of the combustion chamber 14 and the lower wall of the water chamber 17. The cover or wall 26 of the combustion chamber is removable for the reason that it carries at its upper end the check draft damper and as this damper is hinged on the inside it is-necessary to have an opportunity to place the bearing surface of the damper. This can be easily done if this wall 26 is removable.

Furthermore, by making this wall 26 removable, it permits the smoke fine to be cleaned out. It will be seen that the cover or wall 26 engaging in the offset opening 40 of the ring 39, holds anyone of the rings 39 from turning around the magazine. The hover, however, may be rotated upon this supporting ring 39 as desired.

I do not wish to be limited to any specific vmeans for connecting or holding the sec- I tions together, but I have illustrated bolts 45 holding the section 11 onto section 10 and bolts 46 extending upward from the upper end of the section 11 to the flange 43 of the upper magazine section and water chamber.

Obviously these bolts might be arranged in a different manner without departing from the spirit of-the invention.

The thermostat 47 is of any usual or suitable type, but I have illustrated this theri mostat diagrammatically. It is mounted upon a bracket 48 and operates the arm 49 which is connected to rod 80. WVhen the heat increases beyond a predetermined point the thermostat pushes the arm 49 down, which of course, closes the draft damper 31 and opens the check draft damper 28. When the heat decreases beyond a predetermined point, the thermostat moves in an-opposite direction lifting the arm 4-9 and causing the opening of the draft damper and the closing of the check draft damper. I do not wish to be limited to this as I have stated before, to any particular construction of this thermostatic means.

As shown in Fig. l, the rod 30 passes loosely through the eye on the draft damper 31 so 7 that rod 30 may be raised and the check draft damper closed before the draft damper opens and vice versa, the draft damper may close before the check draft damper opens.
