ALLEN P. GREQUE, OF NEWV YORK, N. Y.

STAND-BOILER AND CONNECTIONS.

SPECIFICATION forming part of Letters Patent No. 263,767, dated September 5, 1882.

Application filed June 1882. (No model.)

To all whom it may concern I Be it known that I, ALLEN P. CREQUE, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvementin Stand- Boilers and their Connections for heating and supplying water for domestic and other purposes, of which the following isa specification.

The object of my improvement is to obtain a circulation for the hot water through the pipes which supply the'hot water for consumption for domestic and other uses.

I have described in three applications for patents lately filed in the United States Patelsewhere.

ent Office an improved system of constructing range-boilers and their connecting-pipes, by

which I obtain a more positive, rapid, controllable, and constant circulation of the water, and by making use of the principles of construction set forth and claimed in those applications, I am enabled to construct a boiler and its connecting-pipes which shall cause a posi tive, rapid, controllable, and constant circulation of water from thesource of supply to the boiler, thence to the heater, and then through the pipes which supply'the hot water to the different parts of the building for consumption back into the boiler.

By the system of constructing range-boilers now practiced, and which I have illustrated inthe above-mentioned applications, there is no circulation through the pipe which supplies the water for consumption, and it is necessary for the consumer to draw off the cold water already in the pipe before he obtains a supply of hot water from the boiler, while added to this delay is that caused by the necessity of supplying the boiler with hot water before the supply-pipe is filled. My improved method of constructing the boiler enables me to obviate these objections and to procure the results of mypresent invention by arranging the boiler and its connectingpipes as shownin theaceompanying drawings, in which- Figure l is a sectional view of a boiler, heater, and system of pipes as arranged for a water-supply from the main. Fig. 2 is a sectional view of a boiler, heater, and system of pipes as arranged when the water is supplied from a tank at the top of the house or Fig. 3 isasectional view of an arrangementin which the boiler may be placedin the cellar or other convenient position when the supply comes from a tank.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings, it will be seen that, while I construct the boiler and its connections in a form to embody the invention shown in my three former applications above alluded to, my present improvement is effected by lengthening the pipe which supplies the hot water to the boiler, so as to make it pass directly from the heater through the several stories of the building until it reaches the top story, where it is bent and returned back through the several stories to the top of 0 is the portion of pipe which conveys the cold water to the range water-back.

B is the water-back in which the water is heated.

his the pipe through which the hot water passes from heater for consumption and into the boiler.

20 is a Wastepipe, through which the boiler is emptied when it is desired to clean it, and sis a stop-cock which opens and closes the waste-pipe.

m isa stop-cock which opens and closes the pipe from the main or tank when the boiler is to be emptied, or for any other reason.

M indicates the pipe from the main, and indicates the tank.

f indicates the faucets from which the hot andcold water is drawn.

Referring to Fig. 1, it will be seen that the cold water from the main passes into the boiler through the pipe 0, which is curved at its inclosed end to prevent the water from spouting into the boiler. Itpasses from theboilerthrrough 0 into the heater B, and thence through the pipe h, which is shown in dotted lines in Figs. 1 and 2 as passing behind the boiler A, to the top of the house, and back into the boiler at the upper part thereof.

I prefer to tap the descending branch of the hot-water pipe h for the supply of hot water to the diflerent floors, as a steady flow is thereby secured; but the ascending branch may be tapped instead, if desired.

In the arrangement shown in Fig. 1 the cold water may be supplied directly to the heater without passing through the boiler; but such delivery is not so good as that shown in the drawings, unless the water he also arranged to circulate from the boiler, because with circulation through the boiler, it the supply from the main should cease from any cause, the water would siphon out of the entire system and the range water-back would burn out.

Fig. 2 illustrates my improved method when the cold water is supplied from a tank. The water flows from the tank it through the pipe 0, thence'to the pipe 0 and into the water-back B, where it is heated. It flows thence into the pipe h to the top of the house and back through the descending branch of the pipe h, which is tapped for consumption, into the boiler, at the upper part thereof. It flows out of the boiler into the pipe 0, thus creating a constant circulation.

I have found that by these methods of con- 'struction'just described I can raise hot water to a height of over one hundred and fifty feet, while I obtain a constant, controllable, rapid, and positive circulation, which enables the consumer to draw hot water immediately from the faucet without waiting for the cold water in the pipe to be exhausted, and without waiting for the boiler to be filled with hot water, as was necessary in the old method.

It is apparent that I am not confined to placing my boiler by the side of or above the range, as must under present systems of circulation be now done, in order that the water may not siphon out; but I may, if desired, heat the water in a water-back attached to the furnace or other heater in the cellar, and lean place the boiler in the cellar; and my invention makes such an arrangement safer than it would be in the old method of construction, as I have a positive and constant circulation which is notliable to get out of order.

Fig. 3 illustrates the method which I prefer to adopt when the water is supplied from a tank at the top of the house, as it obviates the necessity of placing the boiler in the kitchen, where it is not desirable, either in nicely-finished houses, or when, as in apartment-houses, the size of the boiler is greatly increased to supply all the tenants. In this arrangement I place the boiler in the cellar or other convenient place, as desired, and lengthen the pipe 0 so as to reach the water-back of the heater. Otherwise the arrangement of pipes is precisely as shown in Fig. 2, and the water follows the same circulation. ."The same arrangement may be adopted where the supply the system and the water-back would burn out.

This arrangement is not therefore as valuable in such a case as when the water is supplied from a tank. It is also obvious that I may place the boilers in these systems in a horizontal position and arrange the pipes as shown in my application for Letters Patent of the United States filed May 19, 1882, without impairing the value of my invention here shown and described.

Having thus described my invention, what I claimis 1-. The combination of a boiler, heater, and system of pipes, arranged substantially as described, whereby the cold water is delivered into the heater, thence into a hot-water-supply pipe extending to one or more faucets, for

consumption, and thence into the boiler and heater, substantially as described.

2. The combination of a tank, boiler, heater, and system of pipes connected and arranged substantially as described, whereby the cold .water from a tank is delivered to the heater,

thence into ahot-water-supply pipe extending to one or more delivery-faucets, and thence into the boiler and heater, substantially as described.

3. The combination, in a bnilding,ofa boiler, heater, and system of pipes for supplying hot water, connected'and arranged substantially as described, whereby-the water is delivered directly into the heater, thence through a pipe or pipes to one or more'delivery-faucets, thence to a boiler located in the cellar or other convenient place below the heater, and thence to the heater, substantially as described.

at. The combination, in a building, ot'a boiler, heater, and system of pipes for supplying hot water, connected and arranged substantially as described, whereby the water is delivered into a boiler located in the cellar or other convenient place below the heater, thenceiuto the i ALLEN P. OREQUE.
