STOCK-TAN K HEATER.

` Speccaton of Letters Patent. Patented Sept. 24, 1918,

Application led April 9, 1917. Serial No. 160,785.

To all 'whom t may concern:

Be it known that I, OSCAR SUBBY, a citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Stock-Tank Heaters, of which the following is a specification.

This invention relates to stock tank heaters.

The object of the invention is to provide a heating device for stock tanks capable of being readily placed within the tank and having its major portion located beneath the level of the water therein, in order to maintain the latter at a temperature to prevent freezing when the tank is located in an exposed position.

Another object is to provide a heating device for the above purpose, which may be readily adapted for the use of oil as a fuel for generating the desired heat, or which may be readily arranged for the consumption of other fuel, such as wood, coal, cob's, etc.; the device having provision forvsupplying fuel in a manner which obviates the necessity for frequent attention in replenishing the same within the lire chamber.

A further object is to provideV means for controlling the drafts to the fire chamber whereby, upon starting a fire therein, air may be admitted beneath the fuel to accelerate combustion, and, by manipulating certain dampers, the course of the air may be changed and admitted upon the top of the fire so that the latter will be checked and the heat confined to the'. bottom of the device, where submerged, and caused to traverse a heat radiating member forming part of the device, to obtain a complete circulation of the heated water.

A still further object is to construct a heater of this class having a shell or casing composed of a single casting, thus dispensing with rivets, bolts, or other fastening means, which are liable to become rusted and destroyed through the action of the water, and to provide a heater which is capable, when not desired for use as above described, of being removed from the tank and installed for use in heating a room, barn, or other inclosure,A without the necessity for any changes or alterations whatever.

A full and complete understanding of the invention will be obtained upon a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification; it being understood that while the drawings show a practical form of the invention, the latter is not conlined to strict conformity therewith, but may be changed or modiiied as long as such changes or modifications mark no material departure from the salient features of the invention, as specically pointed out in the appended claims.

In the drawings, in which like reference characters designate like parts in each of the several figures:

Figure l is a side elevation of the improved heater arranged for the use of oil as a fuel.

Fig. 2 is a vertical longitudinal sectional view thereof, the oil supply tank being in elevation and shown in position within a stock tank.

Fig. 3 is a plan view of the device, the oil supply tank being removed.

Fig. 4 is a horizontal sectional view on the line 4 4 of Fig. 2.

Fig. 5 is a vertical longitudinal sectional view similar to Fig. 2, showing the device adapted for the use of fuel other than Oil and located within a stock tank.

Fig. 6 is a detail plan view of the fire chamber, with the top removed.

Referring to the drawings, there is shown a stock tank heater of the submergible type,

lin which the entire casing, including certain radiating means to be referred to, is preferably cast in one piece, thug eliminating all rivets, bolts or other fastening devices, which rapidly succumb to the action of the water and render the device unfit for use. The casing includes a vertically disposed tubular fire chamber 1 having a bottom 2 and an open upper end and is adapted to be placedv within a water tank 3. The bottom 2 is supported in spaced relation to the bottomof the tank 3 by a leg member 4, thus providing a space beneath the fire chamber for the free passage of water.

The chamber 1 is of suliicient height to extend above the maximum level of the water within the tank and has means provided at its upper open end for the detachable and pivotal connection thereto of a lid or closure 5. The lid 5, in the present instance, consists of a flat, circular cast iron plate,

having thereenertan means. for `central- ,passageway or ,port `7 is provided at the lower vend ofthe air duct and connectsthe same `with the llower portion .of the tire chamber 1 1.

At a lpoint diametrically opposite from the air duct 6, a hollow .radiatingarm S is provided, which ,is cast integrally .with the lire chamber 1 and extends laterally a distance Iapproximately .equal ,to the height oi' the ire chamber 1. The arm 8 may, however, extend a much greater or less distance and is of a width, .interiorly, equal-to the diameter of the fire `chamber .1. The arm 8 is joined to the fire chamber `1 at a point substantially one third of the-height ofthe lire chamber, from the bottom thereof, and is adapted .to be supported lat its outer end by a suitable leg 9 resting upon the bottom of the tank` Thus, the hollow arm 8 is supported a considerable distance #from the bottomotl the tank and permits of a volume of water to lie beneath the same.

An upstandingtubular stack 10 `is cast integrally with the hollow .radiating arm at the outer end thereof, and communicates with the passageway therethrough. This stack 10 extends upwardly a distance equal to the height of theftire chamber 1, and thus the upper end thereof is located above the level of the water within the tank 3,. A suitable smoke pipe 11 is applied to the upper end of the stack 10 and has a suitable damper 12located therein within easy reach of an operator.l

Vertically disposed .water passages 13 are cast integrally with the hollow radiating arm 8,the.diamcter ,of-said passages 13 being considerably less .than `the width of the hollow arm `8, thus allowing ample space i upon -yeither side of the passages 13 for 4the ready,.egress of the .productsoi combustion from the fire chamber 1. that ,-aA column of water located `within the wallsof the passages will -be completely surrounded by the/heated products passing through the hollow `arm 8 and that @there will .bea ,constant tendency for the heated water to`rise therethrough, drawing other and lcolder water therein, thus 4,causing a .constant `circulation,ot1 ,water Lwithin the tanln ltvwill, furthermore, be seen, ithat by y reason ,ofthe Vspace beneath the I chamber .-1,

and which is adapted to permit the ready inflow of air through ithe -port-7 A grateimember l.16,of thesame diameter as the ash vreceptaclela, is adapted to abe supported by the topedges ofthe-walls -ot thelatterand tofbe spaced awaytherefrom by legs A1.7, thus -providinglairinlets elSitherebetween immediatelybelow grate.;bai's 419 yin the grate niember'l and adapted to support the `rebed, .whensuch fuel as wood, coal, cobs, etc. is used. The grate member 16 is provided, around the top .edge fof its annular wall, with ia-.series .of Vspaced upstanding fngers 120 :adapted .to confine said fuel Within the gratemember 16, and at `the same time to permit of lthe yready. upward passage Vof the air currents .through and i around .the fuel.

A horizontally disposed lug-21. is l:termed on the `fire chamber 1, directlyeover the center line ofithe arm .8.and at a pointslightly below the top ,edgeiof thetire chamber 1, thus being located above the water level `within the Atank 3.y This lug 21 is 4provided with `a vertically `disposed passageway -22 with which communicates `a slOt 23.

The lid `5, .shaped .f to fconitorm tothe outlines ofthetire chamber land the air duct l, extends slightly beyond the marginsthereof` .and is provided `with la downwardlyextending pivotal post 2.4, adapted 4to traverso the passageway 22 and Vto permitl of the ufeadyswinging-.movementof .the lid in either direction laterally; The pivotal post 24: is providedatitsilower extremitywith an outstanding lug 25, which,when,thelid 5 is ,properly .seated upon the -ire 4chamber 1, :is zadapted to prevent the remo-vallei the lid from its seat -byunderriding thelugl..

. When it is desired to. apply the lidto'the firechamber 1, or toremove :the same there. from, it is necessary toturn said lid-halfway around so that the lug 2,5 will register with the slot `23, .the latter bei-ng directed Vtoward the axis ofthe lirechamber @1. The pivotal post 2a rextends,slightlyrabove the top sur- Suitableisliding,dampers27 and 28of ordinary construction, lare ,mounted `on the lid f l5 over-the,cente rs ogf the -irechamber Land rthe airduct 6, respectively, and are adapted tto regulate theintlow otairq'through suitable apertures,- ina well'knownmanner. A n

aperture 29 1s provlded in the lid 5 at a` point .adj acent to :the sliding dam-pen?? d.

thus communicates with the interior of the fire chamber 1. The aperture-29 is preferably surrounded by an'upstanding annular wall, which is adapted to receive a plug 30 or other closure, when the stock tank heater is arranged for the use of coal, wood, or cobs, as a fuel, as indicated in F ig. 5 of the drawings.

Then it is desired to use oil as a fuel within the receptacle 1, the lid 5 is swung to one side suliiciently to permit of the removal of the grate member 16, and the ash receptacle 14:, preferably with a quantity of ashes therein, is left in position within the bottom of the fire chamber 1. The plug 30 is then removed and an oil tank 31 is placed in position upon the top of the Alid 5. The oil tank 31 which may be of any desired capacity has, near the periphery of its bottom,

a downwardly extending post 32 suitably secured thereto. The post 32 is reduced at its lower end to enter the socket 26, thus locating the tank 31 in proper position upon the top of the lid 5.l Suitably spaced legs 33 carried by the bottom of the tank 81, rest upon the top of the lid 5, and in conjunction with the post 32, serve to maintain the tank 31 in a horizontal position at all times. An oil outlet 34 having communication with the interior of the tank 31 and controlled by a valve 35 has a spout 36, which, when t-he tank is properly located, is in eXact alinement with the aperture 29 and will permit of the dropping of oil therethrough into the interior of the lire chamber 1. Y

As before stated, a quantity of ashes is preferably left within the receptacle 1li when it is desired to utilize oil as a fuel. A small fire, such as supplied by the burning of paper, shavings, or `other likematerial, sufficient to ignite the oil as it drops through the aperture 29, is first started within the receptacle 14 and the lid 5 closed, when continuous dripping of the oil will cause the steady burning of the re at-the eXtreme lower end of the fire chamber 1.

In the event of it being desired to burn wood, coal, or cobs, or other like fuel, the grate member 16 is positioned within the lire chamber 1, the oil tank 31 removed as before explained, and the aperture 29 closed. lt is necessary in order to force the fire at the starting thereof, to close the damper 27 at the top of the fire chamber 1 and to open the damper 28 at the top of the air duct 6. This causes a downdraft of air through said duct k6 which air will travel about the burning fuel contained within the grate member 16, part of the same entering through the air inlets 18, and thus up directly through the fire and on out through the hollow radiating arm 8 to the smoke pipe 11, where the draft may be controlled by the damper 12, as desired. When the fire has gained sufficient headway, the damper 28 in the air duct 6 may be closed or partly closed, and the damper 27 opened sufficiently to cause a downdraft of air directly upon the fire, which will be checked thereby, and the heat confined to the lower portion of the fire chamber 1 and to the radiating arm 8.

In the latter use of the device, the fuel after the lire has been started may be piled into the fire chamber 1 to the top thereof, when the same will be fed to the lire as itis consumed thereby.

From the foregoing, it will be seen that a stock tank heater formed of a single casting has been devised, which is capable of manufacture at a very low cost, and which, being free from rivets or bolts or other parts li able to rust and destruction, is well adapted for use within a stock tank where it is necessary to submerge nearly the entire heating device. By means of the dampers 27 and 28, an operator is enabled to control the fire within the heater without the necessity for frequent attention thereto and with an economical use of fuel. It will also be seen that the device may be readily set up for use elsewhere than in a tank.

Another use that the device is capable of is that the same may be of service for cooking, as the hollow radiating arm 8 is formed with a flat top so that food stuff or the like can be placed uopn this arm and the heat circulating therethrough will radiate through the top, for the cooking of such food stuff. It will be noted that the arm is of a width substantially equal to the Width 100 of the fire chamber, thereby giving the maximum heating surface at its top, while the tubes 13 are vertically disposed to provide passages for the circulation of air therethrough when the device is used for cooking 105 purposes. Additionally, the device may be used as a heating stove for rooms or the like, and such use will be clearly obvious.
