Letters Patent No. 90,541, dated May 25,wl'SjLMA...w- .--AMAA y INIPRO'VEMENT IN BRANCH STOP-COCKSFOR m8.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.'

Be it known that I, It. A. HILL, of Washington, in the county of Washington, and District of Columbia, have invented a new and valuable Improvement in a Branch and Stop for Use of Fire-Plug; and I do hereby declare that the following is a full, clear, and exact description of the construction arid operation of the same, reference being had to the annexed drawings, making a part of this specilicatiom'and to the letters and figures of reference marked thereon.

Figure l, of the drawings, is a top plan view of my device.

Figure 2 is a longitudinal section, of the same.

My invention relates to hydraulics; and

v It consists mainly in constructing a four-way branch, to be placed at the centre of the four corners of streets, adapted to receive the water from each of the four street-mains, and, uniting the four streams into one, couduct'the whole t a irefplug on the pavement.

It also consists in constructing a hollow plunger, with openings, adapted to the four-way branch, and so arranged as to enable the operator to direct the course of the water into and out of the branch, or to stop it in the mains and from the lire-plug, simultaneously, at will.

The letter A, of the drawings, represents a cylinder, to which are attached the four arms B, in the manner shown, said arms being hollow, `and adapted for connection, respectively, with the street-mains, and toreceive the water therefrom.

The lett-er C is the plunger. rlhis is made hollow, and adapted to fit in the inside of cylinder A, and rotate therein.

I make four openings in this plunger, one on each side, adapted to the water-capacity of arms B. These openings are-marked D on the drawings.

The letter E is a cap, screwed on to the dange o, which flange forms the upper end of the plunger, as

shown.

The letter F is a standard, attached to the top of the plunger, the top of which is made square, to adapt it for turning by a wrench.

This standard rotates inside of a collar, which forms the upper projection of the cap E, and which is marked e on the drawings.

On t-he inside of the' top of cylinder A, and on the. shoulder upon which the ange of the plunger rests, I

affix a pin; and I also cut out a portion of said ange, so that the plunger may move back and forth on said shoulder, and be stopped byV such pin in both directions.

For the purpose of actuating the plunger, and thereby opening or closing the openings D, in addition to the square top ofthe standard above mentioned, I aflx to said standard the ratchet-plate G, as shown. I further adjust a frame to the side and top ofthe cylinder A, and in said frame adx the standard s and the pinion u, as represented.

The upper end of standard s' is made in a quad-- rangular form, and adapted for operation, in the usual manner, by a suitable wrench.

The letter H is a conducting-pipe, leading from the bottom of the' cylinder A to the tire-plug on the pavement. I usually adjust it, with screws, by its flange, which corresponds, in size and shape, with the lower flange on said cylinder.

The capacity of this conducting-pipe is the same as that of the plunger, and itsoce is to conduct the water collected from the four street-mains to a replug at the pavement of the street.

To operate my device, I turn either the standard F or s, by which means the openings in the plunger are brought opposite the openings in arms B, andthereby' the water admitted; or said openings D are brought to the side of the cylinder, where there arevno openings, and the water shut off.

' My device is found to be of great value in streets where the supply of` water is small, and one main inadequate to the requirements of remen during a con- Hagi-ation. v

What I claim as my invention, and desire to secure by Letters Patent, is-

The hollow plunger C, with its openings D, the fourway branch, as described, the ratchet-plate G, standard s, pinion u, and conducting-pipe H, combined, arranged, and operating substantially as set forth.I

In testimony that I claim the above, I have hereunto subscribed my name, in the presence of two witnesses.

.R. A. HILL.
