IMPROVEMENT IN WATER-SUPPLY PIPES.

Specification folining part of Letters Patent No. 196,745, dated November 6, 1877; application filed Toall whom it may concern:

Be it known that I, CHAnLEs L. DRmss LEIN, of Chicago, county of Cook, and State of Illinois, havev invented a new and useful Improvement in Water-Supply Pipes, which is fully describedy in the following specification, reference bein ghad to the accompanyin gdrawings, in whichl Figure 1 represents a plan view of asquar or block with my auxiliary water-pipes laid. around it; and Fig. 2, a detail section, on an enlarged scale, taken on the line x x, Fig. 1.

The object of my invention is to provide for a large supply of water, incase of iire, at the immediate locality of there, which can be made available for the supply of water to an engine placed 'close by the burning building.

The invention consists in auxiliary waterpipes laid around a square of buildings, or a portion thereof, above the ground, and connected with the main supply-pipes, so that the water from the latter may be turned into the former at will.

It also consists in arranging the auxiliary pipes in a slightly-inclined position, so that v the water-may be entirely drained from them when not in use. y

It also consists in special combinations of devices for connecting the auxiliary pipes with the mains, and providing for the coupling of hose to the former, all of which will be hereinafter more fully set forth. h

In the drawings, A represents the sidewalk between the houses and curb-stone; B, thepavement of the streetadjacent; and G, the supply-pipe or water-main laid along the street under ground, in the usual manner. An auxiliary water-supply pipe, D, is laid above the ground, extending along next to the curb. This pipe is preferably arranged upon two sides of the square, as shown in F-ig. 1 of the drawings, so that two pipes will be employed to surround the entire square. These auxiliary pipes are connected with the main supply-pipes in two opposite streets at diagonally-opposite corners of the square by means of service-pipes E, one of which is connected to each end of the pipes D, and is extended down into the ground, and then outward, to connect with a T branch pipe,

any other point, and therefore all water may be drained from them, after communication with the main pipes is closed, by means of an intermediate outlet, conveniently located for this purpose immediately above or underneath the ground.

In the drawings a plug, H, is represented as inserted in the ends of the service-pipes, where they join the branch coupling F, by means of which this draining of the auxiliary pipes may be accomplished; butan outlet may be provided at any other point which will permit the same result to be effected.

Thepipes D are provided along their entire length with suitable hose-couplings I, controlled by a stop-cock or valve of any ordinary construction. These couplings may be arranged at such intervals along the street as maybe desired, one being placed opposite every house in the square, if wished.

The pipes D are made of large size, so as to take a large quantity of water from the streetmain, and therefore, whenever a re occurs, several engines can be located close -to the burning building, and supplied with water from the pipe D by coupling to the plugs I. y Itis evident that by this means the difficulty of forcing water through long lengths of hose from an engine stationed at some distance from the re is entirely obviated, and thereby a great saving in the cost of hose is effected,

and also the force of the engine is almost entirely utilized in throwing water directly into or upon the building, instead of losing a large percentage in forcing the waterlong distances through ho se. The supply of water will always be sufficient and in readiness, and obtained by pipe. The connections between thel branch' pit, ifdesired, so as to be readily:

simplyturning the plugs Gat one y or `both ends ofoneior niorefof the ,auxiliary pipes, `thereby opening communication with the mains.

After use, and especially in cold Weather, communication between the mains and auxiliary pipes should be closed, and the latter drained, as above described. In ordinaryl weather the plugs I, at the lowest points of the pipe, may be used for this purpose; butti when there is danger of freezing the drainingoutlets should be' under ground.

It is not absolutely necessaryto put these auxiliary pipes around every square in aH city, as it is evident that by surrounding each alternate square there would be one of these supply-pipes in every street, within convenient distance of the `houses thereon; but of course the supply of Waterwill be much greater if `the` auxiliary pipes are laid around every square.

Instead of the arrangement described, the pipe D may be laid along the street parallel to the main C, and connected at everysquare, orl two or more squares, with `the main, `as described, so that the water from the main .may be diverted into the auxiliary pipe,and returned again to `the saine main pipe. The auxiliary pipe should be made as large, orl nearly so, as the main, where the latter is small, so that nearly the entire supply of water may be, diverted from the main into .the auxv iliary pipe.

The couplings in the auxiliary pipes lmay` also beused for attaching hose directly thereto d without the intervention of an engine for lserv-` ice in case of ire,or anyfother Ause desired; and standfpipes 7 Aare employed, `they `may be coupled tothe auxiliary pipes whenever occasion requires.

Having thus described my invention, what Iclaim as new, and desireto secure by Letters Patent, is-

1. The auxiliary Water-supply pipes D, laid in the `street above ftheA `ground or pavement, around or along a square or block of buildings,

and provided with a series of plugs, I, in combination with the water-.main C, with which the auxiliary pipe is connected, so that water may be admitted to or shut oli therefrom, substantially as and for the purpose set forth.

` 2. The auxiliary pipes D, extending around` vtWo sides of a block orsquare, connected with the mains in two opposite streets, `and laid Ain an inclined plane,"as describedfsubstantally as and `for the purpose set forth. y t

3. The auxiliary pipes 1),;arrangeduponthe` street, above the surfacethereof, as l described,` in `combination with the main supply-.pipes C, the serviceor `connectin g pipes E,coupling F, and valves Gr, substantially as described.

4. The service-pipes E,in`co1nbination=with y the branch coupler F,main `pipe G, valves G, and plugs H, substantiallyas and `for the purpose set ilibrth, p
