GIRGULATING HOT WATER HEATER.

N0. 363,165b Patented May17,1887.

UNITED Srrns RUSSEL B. OXVEN AND OLNEY B. FULLER, OF DETROIT, MICHIGAN, ASSIGN- OBS TO THE SMITH 82 OWVEN HEATER COMPANY, OF SAME PLACE.

CIRCULATING HOT-WATER HEATER.

SPECIF C ION forming part of Letters Patent No. 363,165, dated May 17, 1887.

Application filed May 10, 1886.

To all whom it may concern:

Be it known that we, RUssEL B. OWEN and OLNEY B. FULLER, of Detroit, in the county of Wayne and State of Michigan, having invented new and useful Improvements in Girculating Hot-Tater Heaters; and we do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawing which forms to a part of this specification.

This invention relates to certain new and useful improvements in circulating hot-water heaters; and it consists in the peculiar combinations and the novel construction and arrange- 5 ment of parts, all as more fully hereinafter described and claimed.

In the accompanying drawing. our inven tion is shown in sectional elevation, and A represents a boiler consisting of a double shell surrounding and inclosing an annular waterspace, a. V

F is a vertical or direct pipe, communicating with the water space of the boiler near its top and leading to a coil or radiator, G, whence it 2 5 descends, following the pipe H, which leadsinto the water-space of the boiler near its lower end.

0 is a feed-pipe, forming a communication between an elevated tank, D, and the lower part of the water-space of the boiler, prefer- 3o ably, although not necessarily,through a 'F at the lowerend of the return'pipe, as shown at I).

E is an overflow-pipe from the tank.

I is a water-supply pipe discharging into said tank,and provided with a valve, 0, which 5 is operated by means of the float J, secured at the end of the arm d, the other end of which is connected with the valve.

In practice, the boiler, circulating pi pcs, and feedpipe being filled with cold water, and

o the tank filled to the top of the overflow-pipe, a fire is made in the furnace. As Water under certain conditions of heat expands, such expansion will force a small portion of the water in the feed-pipe to discharge into'the tank and 5 out of the same through its overflow-pipe. If a smallquantity of hot water is new wanted Serial No. 201,672. (No model.)

for any purpose, it may be obtained by opening the cock K in the return-pipe I-I. \Vhat is withdrawn will be immediately supplied from the tank through the feed-pipe, the weight of the column of water in such pipe being sufficient to overcome the pressure in the boiler. This lowers the surface of the water in the tank below the top of the overflow, and the float, following the falling surface, opens the valve in the supply-pipe and lets the water therefrom fill the tank again to the proper height. If from any cause a leak or obstruction should be found in the circulating-pipes, the water may be withdrawn from such pipes by closing the valve 6 in the vertical pipe F and the valve h in the return-pipe H and opening the cock K in the latter-named pipe, thereby avoiding the necessity of drawing off the water in the boiler, as has heretofore bee required.

Some of the features herein shown, but not claimed, are shown and claimed in an application tiled of even date herewith by Peter Smith and Olney B. Fuller, and numbered 201,670.

What We claim as our invention is The apparatus described, consisting of the nected with said water-space near the top thereof, direct pipes F, communicating with said tank, independent coils G, return-pipe H, connected with the bottom of the water-space, elevated tank D, feed pipe 0, connecting said tank with the lower part of the water-space, the return-pipe H, connected at b with the feed'pipe O, overflow-pipe E, feed-pipe I to said tank, valve 0 in said feedpipe, float J, regulating said valve, the cock 0 in the direct pipe F, valve h in the return-pipe, and the cock K in the return-pipe between the valves 0 and h, all combined, arranged,and operating substantially as and'for the purposes specified.
