JOHN F. MAQKAY, OF BORDENTOIVN, NEW JERSEY.

HOT-WATER HEATER FOR BROODERS AND INCUBATORS.

Application filed December 16, 1913.

To all whom it may concern:

Be it known that 1, JOHN F. MAoKAY, a citizen of the United States, residing at Bordentown, in the county of Burlington and State of New Jersey, have invented cer tain new and useful Improvements in Hot- Water Heaters for Brooders and Incubators, of which the following is a specificatlon,

reference being had therein to the accompanying drawing.

My present invention relates to certain new and useful improvements in hot water heaters for colony brooders and incubators and for other apparatus requiring an automatic regulation of the heat so that it may be kept at a proper even temperature.

The object of the invention is to furnish a simple, complete and eflicient draft-regulating appliance for a hot water heater of the class specified.

The invention, therefore, consists essentially in the construction, arrangement and combination of the various parts substantially as will be hereinafter described and then more particularly pointed out in the claims.

In the accompanying drawing illustrating my invention: Figure 1 is a top plan view of my improved hot water heater. Fig. 2 is a side elevation of the same in partial section on the line 2, 2 of Fig. 1. Fig. 3 is another side elevation of my improved hot water heater, the same being at right angles to the elevation in Fig. 2.

Similar characters of reference designate corresponding parts throughout the different figures of the drawings.

-1 denotes the ash pit or base chamber at the bottom of the furnace of the heater, the same having the usual door 3. Above the ash pit 1 is a fire box 26, generally of a conical form, and having its surrounding wall 2 made hollow so as to furnish a water space, the whole making a boiler which is entered by the pipes 4, 4 leading to the water jacket 2, from which also pass the pipes 5, 5 that carry the water away from the water jacket. Obviously the pipes 5, 5 lead to the colony brooder, incubator or other device, where it. is desired to apply the heat for practical use, while the return pipes 4, 4 enable the circulation to be complete so that the water can flow back again.

to the water jacket 2.

At the top of the fire box 26, 1s a damper 19, carried by a stem 20. This damper 1s Specification of Letters Patent.

lifted away from its seat 27, formed in the top of the fire box, 26, whenever it is de sired to replenish the fuel, and also. the damper 19 serves as a draft damper, as I shall presently explain, to promote combustion when required. The casing 28 above the fire box 26, provides a damper seat 27 and also furnishes a support for the smoke flue 17 and also for the door 22, which acts as a check damper to check the burning of the fuel whenever it is desired to allow the fire to die down. point in the hot water system as, for instance, on one of the pipes 5 through which the water flows away from the boiler, I find t convenient to attach a thermostat, which is acted upon in the usual way by the heat of the water in the water system, andby means of this thermostat the various doors and dampers for regulating the draft are controlled, and thus the requisite draft supplied can be cut off at the proper time in order to keep the fire burning as brightly or as slowly as may be desired to take care of the proper temperature.

The thermostat may be of any suitable construction and usually consists of the casing 6 connected to the pipe 5 and containlng a spring or other device 8, which operates a rod '7, expanding said rod when the heat increases, and contracting it when it diminishes. The rod 7 is pivoted. to a lever 9 which isv suitably supported in a housing 29 that provides the pivotal support, while the other end of the lever 9 is pivoted to an upright rod 10 having connected thereto, near its upper end, an arm 11, which is pivoted in turn to a lever 12, whose fulcrum is a pin 13 on a standard 18 that is supported rigidly on a top frame 28 of the boiler. A set-screw 30 on the screw-threaded upper end of the rod 10 is employed. to adjust the length of the lever 10 and thus properly regulate the movement of the system of levers. Lever 12 is pivoted to the lower end of a vertical link 14, whose upper end is pivoted to the end of a lever 16 fulcrumed at 31 on the upper end of the standard 18. This lever 16is also pivoted to the stem 20 of the damper l9 and to a rod 24 that is joined to another rod 21, said rods 21 and 24 occupying a vertical position. The rod 21 is pivoted to a draft door 25 in the ash pit 1. Also to the rod 21 is pivotally connected an arm 23 pivoted on the frame 28 and attached to t some suitablethe check draft door 22. A weight 15 is hung on the short end of the lever 16 and serves to counterbalance substantially the weight of the dampers 19, 22 and 25.

The operation of the apparatus will be fully understood from the foregoing description of the various parts without need of much additional description. It will be clearly seen that as the heat of the Water increases, the action of the thermostat will be to push down upon the rod 7, thus depressing the outer end of the lever 9 and pulling down on the rod 10, which will oscillate the lever 12 on its pivot 13, thereby raising link l4 and oscillating lever 16, the result of which will be to force the damper 19 tightly on its'seat and simultaneously close the damper 25 and open the check draft 22, thereby cutting off the supply of air and causing the combustion in the fire box to decrease and the heat to diminish, so that the temperature of the water will drop back. When it isbelow a predetermined point and the cooling water acts on the thermostat, the rod 7 Willcontract, pulling upward upon the lever 9, and thus raising the rod 10, thereby pulling the lever 12 on its pivot I3 in a direction opposite to that in which it was moved before, and pulling downwardly upon the link 14,- thereby lifting the lever 16 and opening the damper'lt), and at the same time closing the check draft 22 and opening the'ash pit door 25, which will place the draft doors in the position in which draft will be permitted, and combustion will thereby be increased until the heat rises again to such 'a degree as to require action of the thermostat in decreasing it. In this way it will be seen that an even degree of heat can be maintained and just the proper temperature kept in the brooder or incubator as may be required, and obviously this degree of heat can be regulated by changing the adjustments of the different parts, so that in every caserthe heating may be performed which will be best suited for the particular service needed.

II-Iaving thus described my invention, What I claim as new and desire to secure by Letters Patent, is

1. In a hot Water heater for brooders, incubators and the'like, the combination of a I boiler, a Water circulating system arranged in connection therewith, a fire box, an ash pit, a damper in the top of the fire box, a draft door in the ash pit, a leverage system for operating said damper and draft door comprising a vertical rod attached to the damper, a jointed vertical rod attached to Copies '01 this patent may be obtainegl for the ash pit draft door, a top horizontal lever pivoted to said rods, a standard providing a fulcrum for said lever, a counterbalanced weight on said lever, and means whereby said lever is operated automatically by the hot water as it increases or diminishes in temperature, together with a check draft damper pivotally supported in the upper part of the boiler, and provided with an arm which is operated by the jointed arm connected to the ash pit door.
