T 0 all whom it may concern:

Be it known that I, CLEMENT V. HILL, a citizen of the United States of America, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Heaters for Brooders, of which the following is a ing out.

One of the objects of my invention is to provide a brooder heater stove in which there is a gas chamber between the top of the magazine and the top of the stove and to provide means whereby said chamber is always in communication with the stove pipe, without aflecting the draft of the stove, said gas chamber being separated from the direct smoke passage in the stove.

Another object of my invention is to provide an automatic regulator for the stove.

A still further object of my invention is to so construct the stove. regulator, and associated parts in su r ianner that the brooder hood is free to be raised and lowered with- Fig. 3 is a vertical sectional view of an.

other embodiment of my invention.

The reference numeral 1 designates a stove body having its greatest diameter substantially midway of its height, the fire pot portion of which is below the greatest diameter and the combustion chamber above the greatest diameter of the stove body, having a fire box 2, an ash chamber 3, and ash door 4. The ash chamber is also provided with a draft opening having a door The top plate 6 of the stove has a peripheral flange 7 inclined downwardly at an angle less than a right angle to provide a bearing surface for the hood as will be here inafter explained. A smoke hole or draft opening 8 is provided in the top plate (5, the stove wall being deflected as at 9 under said smoke hole. In the center of the top plate 6 and central with the axis of the stove an opening 10 is formed, the walls of which are beveled as at 11 in which the magazine is suspended.

The magazine 12 extends in to the fire box 2 the proper distance and is held in position by means of an.annular beveled flange 13 engaging the beveled wall of the opening 10 in the top plate, the two bcvels being formed on the same angle so that they fitwith a practically gas tight joint. The top of the magazine terminates in a flared collar or flange 14, the angle of flare being the same as the angle of bevel of the wall of the 0 ening 10 in the top plate 6. A valve 15 aving a beveled periphery is adapted to fit in said collar 14- ot' the magazine with practically a gas tight joint. Now if for any reason it is desired to dispense with the magazine, it may readily be withdrawn from the stove and the valve 15 used to close the opening 10 in the plate 6. The valve 15 .is pro vided with an operating handle 16 having an elongated stem 17.

On the top of the plate 6 I secure a member 18. This member 18.is provided with base flanges by means of which it is secured by bolts to the top plate 6. This member 18 is also provided with a partition 19 having ports 20, said partition dividing the gas chamber 21 from the smoke passage of chamber 22, the piirts 20 providing exits for gas from the chamber 21 into the chamber 22, the chamber 22 being at all times open to the stove pipe 23. The bottom of the smoke chamber 22 is provided with an opening establishing communication between said chamber and the fire box; the

walls of this opening are beveled as shown in the drawing. A check damper 24 having a beveled periphery is adapted to close this opening in the bottom of the smoke chamber to stop the draft, said damper being carried by an arm 2-5 pivotally mounted as at 526, the outer end of the arm projecting outside the smoke chamber.- Nowgwhen the damper 24 is in closed position the pressure of gas in the stove is sometimes suiiicient to cause it to leak around the periphery of the a damper and the valve 15. From the smoke chamber 22 the gas will immediately escape to the stove pipe, but that leaking around the valve would escape into the room and kill the chicks in the brooder. In order to prevent this I provide a lid 27 tov cover the top of the gas chamber 2-1said lid-having a icentral opening through which the stem 17 of the handle 16 passes, said opening be; ing of greater diameter than the stem where by a space is left around the stem through which air isdrawn by the natural draft of the stove pipe carrying the gas withit from the chamber 21, through ports 20 into the smoke chamber and thence into the smoke stack as indicated by the arrows. This draft is augmented by the fact that the door 28 of the smoke chamber is open when the damper 24 is closed. This same draft of the stove pipe will naturally draw all the gas from the smoke chamber. In order to automatically control the damper and thus regulate the heat of the breeder I provide any from roosting on it. A rod 31 is operatively connected to the thermostat at 'thebottom and at'the top 'is provided with a chain 32 the lower end of which is attached to the door 28of the smoke chamber and constitutes a flexible connection between said rod and door thus permitting the door to swing,

in an are on its hinges without afiecting the vertical movement of the rod. .A rod 33 is also connected to the thermostat and passes through the bottom of the frame 30, its

lever 34 and to the ail (10F 37 of the lower end being pivotally secured to a lever 34 which is pivotall mounted on the lug 35 on the bottom 0 the frame. A chain 36 is connected to theopposite end of the it or. chamberthereby establishing a flexihle connection between said door and lever. 38.is a thermometer suspended from the framt 30 near the floor, as it is at this point "that the temperature of the room must be carefully regulated because the chicks are on the floor.

A hood 39, open at the top and bottom,

is suspended from the stovetop 6, and may be elevated, when necessary,

by means of ropes 40 and running over the pulleys 41 secured to the ceiling of the room.- The upper partof the hood is inclined on the same angle as the flange 7 thereby forming a tight joint therewith whilethe up 1' edge or marginal portion (if the hood is bznt inwardly to constitute a flange 42 which rests on theupper face of thetop plate 6 as shown.

The diameter of the opening in the, top of the hood is such that will clear all Working parts of the stove and regulator, where" by it may be raised and lowered without disturbing any connection between the work ing parts of the organization.

It is obvious from the above description that if the temperature near the floor falls below a predetermined degree the thermostat will automatically pull the rod 31 downward, thereby closing the door 28 of the smoke chamber, and by reason of the pivotal connection 43 between the outer end of the arm 25 and rod 31, open the damper 24 and simultaneously, through the rod 33, q

lever 34, and chain 36 open the air door 37 in the ash pit or chamber thus admitting air to the fire box and permitting the fire to start up. Whenthe predetermined 1 high degree of temperature is attained the thermostat will be again operated and restore the parts to the positions indicated in Fig. 1.

' It will also be seen that chambers are provided above the top of the magazine 12 and above the stove damper 24, .bothof which are at all times in communication with the i stove pipe-23 thus insuring the passage of all gases escaping from the stove directly into the smoke pipe thereby eliminating the escape of the gases in the room. This is very important as coal gas will surely kill the chicks.

As shown in the drawing an arm 44 is pivotally mounted on the frame and connected with the thermostat, and a lever 45. is pivotally mounted on said arm, the rods 31' and 33 being connected to said lever. 46 is a counterbalance'mounted on the lever 45.

In Fig. 3 the damper 47, air door 46, and

ash door 48 are substantially of the same eonstructionshown in Fig. 1' and they are connected to the thermostat rod 49 as shown in Fig. 1. I provide in this construction a peep hole to enable the operator to ascertain the condition of the fire at a y time without "raising the hood and without disturb; ing any of the operating parts, but make this opening of a very small diameter to reduce to a minimum the liability of the escape of gas. The peep opening is made by forming a hole in the top Wall of the chamber 18" and an opening in the top plate 6" of the stove in alinement with each other.

These openings are closed by means of lids The hood 39 is'of the same construction as heretofore described, while the bodyfof the having its sides converge upwardly, a top stove 1 is of different construction in that at the top the walls are flared out, as at 54;; said flare constituting a battle surface for the heat radiating from the sides of the stove. The ascending heat strikes this tbatile and is deflected against thedowir wardly inclined sides of the hood 39 whereby the heat is deflected toward the floor. The cooperation of the flare 54 and hood 0 39 creates a circulation of heated air under the hood and prevents the formation of a dead pocket of air at the top of the hood.

This flared upper end of the stove body enables me to conveniently locate the peep hole between it and the magazines.
