TANK-'HE ATER.

Specification of Letters Patent.

Patented July 30, 1907.

Application iiled October l, 1906. Serial No. 336,812.

To all 'whom it may concern:

Be it known that I, .Tenn S. .IAeonsnN, a citizen ol' the United States, residing at Harvey, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Tank-Heaters, of which the lfollowing is a specification.

My invention relates to tank heaters and has for its object to provide a new and improved heater suitable for use in heating water or other liquid in a tank.

The invention is illustrated in the accompanying drawing, wherein Figure l is a side elevation of the heater, Fig. 2, a plan View ou an enlarged scale with parts broken away; Fig. 3, an enlarged section on line 3 3 el Fig. 2, and Fig. 4, a detail elevation.

Like letters of reference indicate likeparts in all the drawings.

My invention has for its principal object to provide an inexpensive portable heater which may be set into a tank of water or other liquid for the purpose of heating the water therein or keeping the same from freezing, or at any desired temperature. The device could be used, ier example, ier stock farm watering troughs in winter time to keep the water from freezing or from getting too cold. The device will, oi course, be capable of other' and very different uses and might be used also to heat the water in a bath tub or other tank for any purpose whatsoever.

Referring to the drawings, A represents an upper casing, and B a lower casing. The casings A and B are hinged together by the hinge O and means is provided l'or making the connection between them water tight. For example, I may provide the upper casing with the beveled ring A1 and the lower casing with a similar ring B1, a gasket A2 being attached to the upper ring and `filling the space made by the bevels. A latch keeps the easing sections together. I have shown this as consisting oi a pivoted clip D, with a notch Dl engaging with an eccentric stud E on a locking lever El turning on a pivot E2 on the upper casing A. When the clip is vbrought into engagement with the stud E the lever El may be drawn down a suhcient distance to make the connection between the two casing sections tight.

The lower casing B has the alse bottom B2 and below this in the casing is secured a fuel tank F. I may use any sort of luel for heating. I have here shown a gasolene lamp of ordinary type although any sort of heat generator might be used. The tank F has'the screw threaded inlet F1 which is closed by the plug F2 `through which is a passage way F3 controlled by a tion between the block and the lalse bottom. It will be seen that there is a space which I have designated by the letter FJ between the tank and the casing. When the tank is submerged in the water this space will, of course, be filled with water which will effectually prevent any danger due to overheating of the tank. The heater may, therefore, be left unattended all night, for example, without any possible danger of explosion. When the tank has been illed with gaso? lene a sullicient quantity of air may be forced into the tank by means of a small pump such as abicycle pump.

Gr represents in general the gasolene burner which may be of any desired type and as devices of this character are well known in their construction and operation I' shall not describe the burner in detail.

Above the burner is a boiler or Water heater H which may be of any desired type. I have shown it as a tank provided with a number of vertical lues Hl H1. The water heater is provided with one or more inlet pipes .I and the outlets K, K. Above the water heater and connected therewith is a drum L with the central perforation Ll. This aids to keep the heat down around the boiler although it may not be 'essential in all cases. It will be seen that there is an annular space, which I designate by the letter M, between the boiler and the casing A, This permits a supply of cold air to be ied down to the burner. I preferably cover the top of the casing with a netting N to prevent rubbish or other things from falling into the heater. Any preferred sort of cover could be used. For convenience a bail O is also provided. p

I wish it to be understood that I do not desire tobe limited to the exact details el construction shown and described for obvious modifications will occur to any person skilled in the art.

The use and operation ol my device are as follows'.

The tank will 'first be lilled with gasolene and enoughv air injected into the tank to keep up a forced fiame in the burner. The heater will then be set into the tank Voi water. It the water is not too deep the tank will rest There will be a constant circulation of water through the heater and this circulation will also be imparted to the water in the tank. As a result, the heater will in a sense, propel itself around the tank. In case the device is used to supply heat sufficient merely to keep the water in a watering trough from freezing or at a temperature which is high enough to prevent injury to the health of the stock drinking the water. This movement of the heater in the tank and the constant circulation oi the water caused by its operation will result in keeping the Water at a uniform temperature, and it' desired, keeping the water from freezing without getting the water or any of it too hot. The movement oi the water and of the tank in the Water will, of course, in itself aid to prevent the formation ol ice. Such an arrangement will accomplish the desired end with a very economical expenditure oi fuel, since the llame may be kept just hot enough to cause a slow circulation of water through the heater and a slow movement of the water in thev tank. As suggested the heater may also be used for heating or boiling the water in the tank or for other analogous purposes.

I have used the word tank heater in my specification and claims, but it will be understood that I intend by the term tank any sort ol' a receptacle containing the liquid.

I claim:

1. In a iioating tank heater, the combination of a casing comprising upper and lower sections hinged together, with a burner located in said casing, a fuel supply tank with which the burner is connected, a water heating tank extending across the inside of the casing except for a narrow space between said water heating tank and the casing, said tank being provided with vertical heating flues, pipe connections extending from the water heating tank through the casing, and means for making a water tight connection between the upper and lower sections of the casing.

2. In a iioating tank heater, the combination of a casing comprising upper' and lower sections hinged together, with a burner located in said casing, a fuel supply tank with which the burner is connected, a water heating tank lo` cated within the casing above the-burner, pipe connections extending from the water heating tank through the sides of the casing, means for making a water tight connection between the upper and lower sections of the casing comprising a pair of beveled rings, one on the upper and one on the lower section, a gasket interposed between the same, a pvoted clip on one of the sections, and a locking lever on the other section having a stud with which the clip engages.
