for heating oil in tanks to prevent the same freezing.

One object of the invention is to provide a device whereby the oil in the tank can be kept in a warm or heated condition by water, without contact of the water with the oil.

Another object is to provide a heating de vice of this character in which provision is made to dispose of steam, should the water he raised to such a point and thus prevent excessive pressure on the water reservoirwithin the heater.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is an elevation of my oil heating system; Fig. 2 is a top plan view; Fig. 3 is a longitudinal sectional view throughout the system, taken on the line 33 of Fig. 2; Fig. 4 is a horizontal section on the line 44 of Fig. 1; Fig. 5 is a vertical section on the line 55 of Fig. l; and Fig. 6 is an enlarged sectional detail of the valve controlling the overflow from the reservoir, within the heater.

Referring particularly to the accompanying drawing, 10 represents the heater, 11 the water tank and 12 the oil tank which is to be heated. Located within, the heater is a tank or reservoir 13 extending from the front end of the heater to a point adjacent the rear end, so as to provide a heat conducting space 14. Below the reservoir is a burner 15, in which is burned oil or gas. Above the reservoir is a pipe coil 16, one end being connected to the top of the reservoir at the rear end, while the other end extends out through the front of the heater, and is connected to a pipe 17 which extends to and is connected to one endof a coil 18 located in the bottom of the tank 12. The other end of the c011 18 has connected thereto a pipe 19 WhICh extends into a position to discharge nto the top of the water tank 11. Extending from the bottom of the water tank and connected to the front end of the reservoir 13 1s a pipe 20, which is adapted to convey water from the tank to the reservoir. In the forward end of the heater, and above the coil is a stack 21, the heat from the burner passing rearwardly under the reservoir, vertically past the inner end thereof and then forward over the'coil and finally upward into the stack. From the top of the reservoir 13 extends a pipe 22 which discharges into the water tank 11. In the pipe 22 is arranged an automatic valve 23 which controls the overflow from the reservoir 13, and also conveys steam from the reservoir and discharges the same into the air in the top of the tank 11 so that it will be condensed and fall into the tank in the form of Water.

In the operation of the device, assuming the parts to be in the position shown in Figs.

, 1 and 3, and the burner in operation, the Water will be heated in the reservoir 13, rise therefrom and flow through the coil 16, the pipe 17 the coil 18 so that the oil in the tank 12- will be kept in a warm or heated condition, and then returned to the tank 11 by means of the pipe 19. The water from the tank 11 flows through the pipe and keeps the reservoir 13 properly filled. Should the water in the reservoir reach such a temperature that it would generate steam, this steam would pass up through the pipe 22 and be discharged into the top of the tank 11 where it would be condensed in the form of water.

What is claimed is:

1. A water heating system for oil tanks comprislng in combination, a water heater, an oil tank and a water tank, a coil in the bottom of said oil tank, a water reservoir in said heater, said reservoir subdividing the heater into upper and lower chambers, a

heating element in the lower chamber, a coil in the upper chamber connected to said reservoir and the coil in the oil tank, and connections between said oil tank coil and said water tank and said reservoir and the water tank.

2. A water heating system for oil tanks, comprising in combination, a waterheater,

an oil tank and a water tank, a coil in the of the oil tank coil with the top of said wa- 10 bottom of said oil tank, a water reservoir in ter tank. said heater, a heating coil also in said heater In testimony whereof, I affixjmy. signature,
