G. W. GRAVES. HOT WATER BOILER CONNECTION.

Patented Oct. 5,1897.

GEORGE W. GRAVES, OF ROCHESTER, NEYV YORK.

HOT-WATER-BQlLER CONNECTION.

SPECIFICATION forming part of Letters Patent No. 591,098, dated October 5, 1897. Application filed November 30, 1896. Serial No. 613,896. (No model.)

T0 or whom it may concern:

Be it known that I, GEORGE W. GRAVES, a citizen of the United States, residing at Rochester, in the county of Monroe, in the State of New York, have invented an Improved Hot-VVatenBoiler Connection, of which the following is a specification, reference being had to the accompanying drawing.

water-boiler connection whereby hot water may be obtained from the boiler in less time than is now required and a saving of fuel effected.

My invention is fully described and illustrated in the following specification and the accompanying drawing, the novel features thereof being specified in the claims annexed to the said specification.

In the accompanying drawing the'figure is a side elevation of my improved hot-waterboiler connection.

The object of my invention is to enable a person to obtain a quantity of hot water from a boiler of any given size quickly or in a very short time, and for this purpose I connect the boiler at a point above its lower end with a suitable water-heater by a supplementary feed-pipe so arranged that only that portion of the water in the boiler above the supplementary pipe is passed through the heater, the water below said pipe remaining at a lower temperature than that of the water above it. highest temperature attainable in the ordinary way of connecting heaters and boilers is limited to the temperature produced by one passage of the water through the heater until the entire contents of the boiler have passed through. By my invention the user can expeditiously and with a saving of fuel heat a limited quantity of water to that height of temperature which is only limited by the number of the passages of the required water through the heater.

In the accompanying drawing, A represents the boiler; B, the heater; 0, the feed-pipe, provided with valve D and connecting the lower end of the boiler with the heater, and E the hot-water-return pipe, connecting the heater with the top of the boiler. H is the cold-water pipe, which extends a suitable dis- It is a well-known factthat the tance within the boiler, as indicated by the dotted lines. i

I is the supplementary feed pipe, and, where different amounts of hot Water are desired, the additional pipes I I" may be employed.

The boiler may be of any ordinary or preferred construction, and it may be supported My invention relates to an improved hot-' on a suitable standard N.

P is a sediment-cock or discharge-valve. F is the hot-water pipe, connected with the top of the boiler and arranged to deliver the hot water to any suitable cocks or fittings in any desired locality.

The heater B may be of any ordinary or preferred style and arranged to be heated by any preferred kind of fuel;

In the construction shown it is supplied with gas through the pipe T, the water circulating through a coiled pipe exposed to the heat of the burning gas. ter-back of a gas or coal range may be employed as the heater.

The boiler A is provided in its side with an opening J, to which the supplementary feedpipe I is connected. This feed-pipe mayrun directly to the heater or it may be connected with the feed-pipe C. r

I I are additional supplementary feedpipes which are connected, respectively, to

the openings J J, located in the side of the boiler at different heights above the bottom.

Each of these pipes I I is' provided with a valve L L, of any preferred kind, by which the passage of the water through the pipe may be prevented. These supplementary feed-pipes may be all connected together, as

shown, or arranged in any other suitable manner so as to deliver the water to the heater.

In the operation of my invention if the user desires the full amount of hot water which the boiler can furnish he opens the cook or valve D in the pipe 0, and the circulation takes place through the heater and the pipe If, however, he requiresa supply of a certain quantity of hot water in the least possible time, he closes cock D and also valves L L, and then the circulation will take place through the supplementary feed-pipe I, the water in boiler below the opening J remaining still and at alower temperature than that above it. If a larger quantity of hot water is required, it is secured by opening the valve L, and a still larger quantity may be obtained by opening the valve L, the cock D remaining closed at these times. The openings J J J may be located at any suitable distances above the bottom of the boiler, according to the requirements in any particular case.

I claim 1. The combination with a suitable waterheater, of a hot-water boiler, the feed-pipe provided with a valve connecting the bottom of the boiler with the heater, the return-pipe connecting the heater with the top of the boiler, and a supplementary feed-pipe connected to the boiler at a point above its lower end, whereby only the water in the boiler above the supplementary feed-pipe is circulated through the heater, substantially as described.

2. The combination with a suitable waterheater, of a hot-water boiler provided with two or more openings in its sides at different distances above its lower end, the feed-pipe provided with a valve connecting the bottom of the boiler with the heater, the return-pipe connecting the heater with the top of the boiler, and two or more supplementary feedpipes connected to the said openings in the boiler, and valves in each of the said supplementary pipes below the upper one, substantially as described.

3. The combination with the water-heater B, of the boiler or tank A, provided with opening J in its side at a suitable distance below its upper end, the feed-pipe 0 provided with valve D, the hot-water-return pipe E, and the supplementaryfeed-pipe I connecting the heater with the opening J, substantially as described.

4C. The combination with the water-heater B, of the boiler or tank A, provided with two or more openings J J in its side at different points in its height, the feed-pipe C provided with valve D, the hot-water-return pipe E, and two or more supplementary feed-pipes I I connected respectively to the openings J J, the lowest of said supplementary pipes being provided with a suitable valve L, substantially as described.
