UNITED STATES PATENT OEEIGE.
RICHARD A. HILL, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVEMENT IN FIRE-PLUGS.
l Specication forming part of Letters Patent No. 90,540. dated May 25, 1869.
To all whom it may concern:
Be it known that I, RICHARD A. HILL, of 'VVashingtom in the county of Washington and District of Columbia, have invented a new and valuable Improvement in Fire-Plugs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a pant of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a representation of an external front view of my device. Fig. 2 is a top view of the same with the cover removed. Fig. 3 is a vertical section thereof.
My invention relates to lire-plugs.
The letterA of the drawings represents a box set in the sidewalk, and having a waterconductor to the bottom thereof, marked B on the drawings. The letter C is a strainer, ad-
A justed as shown, through which the water passes upward to the fire-plug. The letter D is a man-hole. The letter E is a box adjusted on the top of box A, in which I place a series of pipes, marked F, with outlets G. The letter a is the valve-stem, constructed hollow, as shown, and having a valve, e, attached thereto. The letter c is a screw-nut, working on threads on the outer side ofv the valve-stem, as shown, and having threads on its outside adapted to threads on the inner side of the pipe F. This screw-nut c, when raised, admits the water to the pipe through the hollow valve-stem, and when lowered not only closes the opening to said valve-stem, but also opens or uncovers a small aperture through said stem, marked t',
through which the waterremaining in the pipe may pass outward through a similar opening in the pipe itself. The letter sis a commodated with water at the same time; g
also, that freezing of water in the pipe or valve is rendered almost impossible.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The screw-nut c, in combination with the hollow valve-stem a and the waste-water openings, as described, substantially as and for the purposes set forth.
2. The case E, surinounted by a cap, and containing a plurality of plugs, as above described, and constituting a common receptacle for the leakage, all substantially as described.
3. The combination of the parts A and E of the case with an intermediate plate, in which a plurality of plugs is seated, substantially as described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
` RICHARD A. HILL.

JAMES l. GREvEs, J. M. HYNE.
