BRUN EAU ETIENNE, `OF WATERBURY, CONNECTICUT. i

HOT-WATER BOILER.

SPECIFICATION forming part of Letters Patent No. `518,592, dated April 24, 1894.

Application filed July 19, 1893.

To all whom it may concern:

Be it known that I, BRUNEAU ETIENNE, a subject of the Queen of Great Britain, and a resldent of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements 1n Hot-Water Boilers, of which the following is a specification.

The object of this invention is to produce a hot water furnace which shall be simple, durable and inexpensive, also one in which a great amount of heating surface is secured, and one in which a perfect circulation of water may be relied upon.

This furnace is designed particularly for dwelling purposes, and would be connected with the various rooms in a dwelling by pipes,

to any well known hot water radiator. Any desired number of radiators may be connected and supplied with hot water.

In the accompanying drawings forming part of this specification-Figure l is a central vertical section of my furnace. Fig. 2 is a top plan view, the pipes being omitted. Fig. 3 is a cross section on the line a.' :vof Fig. l looking in the direction of the arrows, and Fig. 4 is a side elevation of one set of the heating tubes detached.

I preferably construct this furnace square as shown, as I find in practice that it enables me to secure better results, both in construction and as a heat producer.

l is a base and ash pan receptacle, and also serves to support the furnace proper.

2 is an ash pan within the receptacle and may be removed by means of a door 3.

4 is the re chamber and may be provided with a lining of fire brick (not shown) if desired. The heater proper consists of an inner and

outer casing

5 and 6, said inner casing 5 surrounding the iire and forming the fire chamber. Between the inner and outer casing is formed the water reservoir 7 in which the water is heated together with several series of tubes through which the water passes. These tubes are directly exposed to the fire, and are arranged to have the flames pass between them. Upon the inner casing and across the rear thereof I form an inwardly extending angular enlargement 8 having a Serial No. 480,964. (No model.)

horizontal portion acrossits breadth which I provide with holes for the purpose of eonnecting vertical pipes 9 which in turn are connected with the opposite side of the reservoir 7 through a series of horizontal cross pipes 10. In the drawingsI have shown four vertical pipes 9 each having a series of three of the cross pipes. Of course the exact number is immaterial since any number can be used as well. In the front of the furnace and Ydirectly in the path of the cross pipes lO I form an enlargement in the reservoir as at 1l by extending the outer casing. The purpose of this is to admit of a free circulation of water through the cross pipes and into the water reservoir when it would be again heated and pass upward.

l2 indicates a cold water supply pipe which I introduce into the boiler through one of the return pipes 13, from the radiators. It will be seen that both the cold water supply and the return water from the radiators are introduced into the boiler at practically the same places. From here the water is free to circulate around the boiler as well as in a vertical direction. In the latter event it would rise in a direct line with the vertical tubes 9 and would mostly pass through them and become heated and travel to the top of the boiler,and off again to the several radiators through the pipes 14. Any number of these pipes can be connected as will be seen, as well as an equal number of return pipes.

15 denotes the smoke pipe. construction.

16 is the door through which the fuel is supplied to the furnace.

It will be seen that this furnace is constructed principally in three sections, the base forming one section, the central portion and top the other twosections. Being constructed in this manner it is easily set up.

Having thus described my invention, I claim l.
