TANK-HEATING FURNACE.

SPECIFICATION forming part of Letters Patent No. 783,066, dated February 21 1905,

Application filed August 13. 1904. Serial No. 220,613.

To all whom it may concern.-

Be it known that I, CHENIA A. NEWBERRY, a citizen of the United States, residing at Alliance, in the county of Boxbutte, State of Nebraska, have invented a certain new and useful Improvement in Tank-Heating Furnaces, of which the following is a specification.

My invention relates to the heating of fluid contents of tanks, and has for its object the production of an improved furnace to meet certain special requirements of use.

In some cases it is undesirable to apply the heat directly to the tank either on account of damage which would thereby result to the tank itself or on account of mechanical inconveniences, such as location or position with respect to other apparatus or the manner of use. As instances of this I may mention the dipping-tanks employed for the immersion of live stock in a medicated liquid, these tanks being usually set in the ground, drinking-tanks, and supply-tanks of various kinds. In such arrangements the heating of the liquid contents of the tanks should be effected by providing a heating-pipe extending outside of the tank through which the liquid circulates when heat is applied thereto.

1 shall describe my invention as embodied in a furnace constructed to be set below the ground-level and arranged to heat a circulating-pipe connected to a liquid-containing tank also set in the ground; butit will be understood that various changes in details of construction and in the mode of connecting and use may be made without departing from the spirit of the invention.

In the accompanying drawings, which illustrate my invention, Figure 1 shows in section an end view of a tank set below the groundlevel and having a furnace of my improved construction connected thereto. Fig. 2 is a vertical longitudinal section of the furnace and heating-pipes, taken on line22of Fig. 3. Fig. 3 is a top plan view of the same, a portion of the top of the furnace-casing being broken away; and Fig. 4 is a transverse section on line a 4 of Fig. 2.

Referring to the drawings, A represents the casing of a furnace designed to be set below the ground-level, as shown in Figs. 1 and 2, and

having, preferably,- sheet-iron sides. The bottom (6 of the casing slopes from end to end, and at the front or end of greatest depth is located a grate B and the usual fuel and ash doors a and a At the opposite end is provided a smoke-flue C for the escape of the products of combustion. Disposed in the upper part of the casing is a pipe D, designed to communicate with tank E and contain liquid to be heated and returned to the tank. Pipe D comprises, preferably, several turns, as shown, to afford a large heating-surface. At the rear of grate B is a diaphragm 7), secured to the sides of the casing and extending from the grate to near the furnace-top. This dia phragm constitutes a combined fireback for the grate and support for the pipe D, which passes through the upper portion. In order to make diaphragm b removable without disturbing pipe D, it is divided on a line 7), which cuts the center of the piping. At the rear of the furnace near smoke-flue C pipe D is supported by a second diaphragm F, attached to the sides of the casing and extending from the top thereof toward the bottom. The turns of pipe D slope slightly, as shown, and pass through this diaphragm, which acts both as an additional pipe-supporter and a deflector for the flames and heated products of combustion. Piping D is connected at one end-say that over the gratewith the lower part of tank E by a pipe connection cl, which extends down through the bottom of the furnace-casing and then over to the tank. The other or upper end of pipe D is connected by a short pipe (l with the upper part of tank E.

The tank E being filled with liquid to a point above pipe connection (Z' the operation of the heater will be readily understood. Flames from the fire on grate B pass up around the pipe D and over the diaphragm Z) through the space between said diaphragm and the top of the easing. This space is shown narrow, but is to be made sufficient in size to give suflicient exit for the fire. The flames and products of combustion then pass along toward the rear of the furnace until they'strike the second diaphragm F, by which they are checked and deflected, so that agreater heating effect is obtained. They then pass out through smoke-flue C.

A furnace of my improved construction is very efficient and durable in use for the purpose designed, besides being easy and economical to manufacture.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a heater, the combination with a casing, of a grate arranged at one end thereof and a smoke-flue at the other, a pipe disposed in the upper portion of said casing and designed to contain liquid to be heated, and a diaphragm arranged near the smoke-flue and constituting a combined heat -deflector and pipe-support.

2. In a heater, the combination with a casing, a grate arranged at one end thereof, and a smoke-flue at the other, a pipe disposed in the upper portion of said casing extending from over said grate to proximity to said smoke-flue and designed to contain liquid to be heated, a diaphragm forming the fireback of the grate and support for said pipe, and a second diaphragm near the smoke-flue constituting a combined heat-deflector and additional pipe-support.

3. in a heater, the combination with a casing, of a grate arranged at one end thereof, a pipe disposed in the upper portion of said casing and designed to contain liquid to be heated, and a diaphragm forming the iireback of the grate and through which said pipe passes, said diaphragm being divided on a line cutting the center of the pipe passing therethrough.

4C. In a heater designed to be set below the ground-level, the combination with a casing having a sloping bottom, of a grate located in the portion of said casing having the greatest depth, a smoke-flue at the other end of said casing, piping disposed in the upper portion of said casing and designed to contain liquid to be heated, an inlet connection for said piping near the end of said casing having the greatest depth, and an outlet connection for saidpiping.

5. In a heater designed to be set below the ground-level, the combination with a casing having a sloping bottom, of a grate located in the portion of the casing having the greatest depth, a smoke-flue at the other end of said casing, piping disposed in the upper portion of said casing and designed to contain liquid to be heated, a tank in proximity to said furnace designed also to contain liquid to be heated, a connection between said piping near the greatest depth end of said casing to the lower part of said tank, and a connection between the other end of said piping and the upper part of said tank.

6. The combination with a furnace having a casing designed to be set below the groundlevel, piping disposed in the upper portion of said casing, to be acted on by the furnace heat, a tank in proximity to said furnace designed to contain liquid to be heated, and a connection between one end of said piping and the lower part of said tank and between the other end of said piping and the upper part of said tank.
