LIQUID-HEATER.

SPECIFICATION forming part of Letters Patent No. 434,225, dated August 12, 1890.

Application iiled September 25, 1889. Serial No. 825,068. (No model.)

To all whom t may concern:

Be it known that I, CHARLES YOUNG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Liquid-Heaters, of which the following is a specification.

My invention relates to the class of devices which heat liquids by immersion therein, and it is intended particularly for heating the water of bath tubs, tanks, and drinkingtroughs for animals, and for preventing the freezing of milk in cans by heating a reservoir of water within which the cans are placed.

'Ihe nature of my invention and the specific construction of the devices which I employ for accomplishing the objects sought will be clearly understood from the following description, reference being had to the accompanying drawings, in which- Figure l is a central vertical section of my heater; Fig. 2, a detached view in elevation of the outer wick-tube of the burner and its attachments; Fig. 3, top view of the burner, showing the lame-defiector with the device upon it by means of which the wick is raised and lowered through the medium of a key; and Fig. 4, a View in elevation of the key employed for this purpose.

The particular burner employed, aside from certain attachments to it, which will be hereinafter described, forms no part of my invention, and it is not necessary that this burner (by which term is included not only the raising and lowering device for the wick, but also the auxiliary feeding-wick) should be employed; but other Argand burners partaking, preferably, of the nature of the ordinary student-lamp burner maybe substituted without in any way affecting the features which constitute my invention.

In the drawings, A is an air-reservoir, which may be of any desired form, though I usually makevit rectangular.

tis a vertical air-tube extending upward from the air-reservoir A to a height sufficient to bring its upper end above the surface of the liquid within which the heater is immersed.

C is an oil-reservoir Xed within the interior of the air-reservoir A and provided with a vertical oil-feed pipe s extending to about the same height as the air-feed pipe t.

Within the tube s is a level-indicator com-y though the shape is not material, so long as.

an air-space of adequate capacity is-formed ,y

about its exterior.

From the base of the air-reservoir A the wick-tube p ext-ends vertically up through and above the oil-reservoir C, and ois a tubu lar passage connecting the air-space surrounding the oil-reservoir C with the base of.

the Wick-tu be p.

Surrounding the tube p is the Haine-wick n, secured to the screw-collar m, which turns freely upon the threads of the tube 1o in the usual way, and to this collar m the sleeve l is connected by means of the lug lo upon the screw-collar m, which lug enters the slot c' in the sleeve Z, whereby the turning of the sleeve raises and lowers the flame-wick. The feed- Wick h is securely fastened at its upper end to the sleeve Z and feeds by capillary attraction through the slots g therein. As before stated, these features of the burner alone form no part of my invention, and they are only described in detail here in order that other features about to be described may be the more readily understood. The sleeve Z extends above the top of the air-reservoir A and is provided upon its upper end with strips f-three or four in number-supporting the flame-deiector D of refractory material. Upon the upper side of the llame-deflector and firmly secured to it are the two cross-wires efor permitting the height of the flame-wick to be regulated.

E is a metal chimney screwed to a flange d upon the top of the air-reservoir.

Particularly when the device is employed for open-air service. it is desirable to shield the flame from the wind, and forthis purpose a hood F is employed, which fits over the top of the chimney, as shown. This hood comprises the crown c, supported upon the IOO double-walled collar Z) bystrips f. The collar b is extended into a conical perforated diaphragm a, which enters the top of the chimney E, and the base of the collar consists of the oblique annular perforated plate a.

G is the key employed to operate the raising and lowering device byinsertion through the top of the chimney, and it consists of a metal rod having a suitable handle and provided upon its lower end with prongs e to engage the cross-wires c. Flanges u are provided upon the lower side edges ot' the airreservoir to be inserted in grooves on a weighted base, if necessary, to prevent the device from floating.

In operation the lamp is lighted, the chimney E being removed for this purpose, and the deviceimmersed in the liquid to be heated to a depth which will leave the upperends of the chimney E and feeding-tubes t and s above the surface. The height of the flame is regulated, when necessary or desirable, by means of the key G, inserted through the top of the chimney, as before described, and the del'iector, spreading the flame toward the surface of the chimney, causes an intense heat, which is rapidly imparted to the surrounding liquid. The hood F, while it permits a ready exit of the products of combustion and unconsumed air, prevents the wind from blowing down the chimney and rain from entering it, the crown c serving as a water-shed, and air-currents striking the chimney being delieeted upward through the pertorations in the base a into and through the interior of the collar b and out through the space above. Should any current ot air be directed downward upon the internal diaphragm a, itis deflected upward by thefornrof the diaphragm and its effect rendered insignilieant. Obviously all external connections whichv would be below the surface of the liquid to be heated when the device is in operation should be made perfectly water-tight.

That I Vclaim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for heating liquids by immersion therein, the combination of the air-reservoir A, provided with the su pply-tube t, the oil-reservoir C, inclosed within the air-reservoir A, and provided with an Argand burner and having the air-duct o, connecting the surrounding air-space with the interior of the burner, and a metallic chimney E, surmonnting the air-reservoir A and inclosing the upper portion of the burner, substantially as described.

2.
