JOHN HYDE, OF NEW' YORK, N. Ya

HYDRANT.

Specicaton of Letters Patent No. 19,029, dated January 5, 1858i.

To cLZL whom it may concern:

Be it known that I, JOHN HYDE, of the city, county, and State of New York, have invented a new and useful Mode of Preventing Hydrants from Freezing; and I hereby declare that the following is a full and exact description thereof.

To enable others to make and use my invention I proceed to describe its construction and operation, reference being hadto one sheet of drawings, hereunto annexed, and making part of this specification.

The same letters refer to the same things in all the figures.

Figure l, elevation of the hydrant as it appears before it is inclosed. Fig. 2 vertical section, showing the hydrant valve closed. Fig. 3 vertical section showing the hydrant valve open. Fig. le transverse section of the pipe, A, with the plan of the top of pipe, B. Fig. 5 cap of the water pipe, B, under side. Fig. 6 the upper side of the same. Fig. 7 the upper side of the piston or valve. Fig. 8 the under side of the valve.

A, the hydrant. B, the water pipe connecting with it. C, the valve rod. D, the waste pipe. E, the space between the open and shut valve. F, aperture to admit air into t-he upper part of the space, E, when the valve is open. Gr, thc collar or shoulder on which the valve rests to shut off the water. H, the valve. l

The part of this hydrant, the construction of which is new, consists principally in the waste pipe, D,v and its connections. The lower part of the rod, C, is bored out, as will be seen in the sections Figs. 2 and 3, and a branch, D, added. The branch, D, being hollow, the two constitute a. Siphon. This rod is firmly set in the valve, H, and the hole closed at the lower end, where the rod is fastened to the valve by a nut. At the top of the valve a hole is bored into the rod so as to make an opening at the lowest point of this end of the siphon.

The cap, seen at Figs. 5 and 6 and in section at 2 and 3 is hollowed out on t-he under side to form a chamber to admit air.

Through the can into this chamber a small aperture, F, is bored, the purpose of which is to admit air into the Siphon so that it can be emptied.

The screw at the upper part of the rod, C, has a swivel joint so that the valve is not turned around in being opened or shut. The valve is opened by means of the screw at the top, in the usual manner. As it is being shut the water fills the siphon, flowing through it until the valve is closed. After the water has run out, down to a certain point, the branch, D, of the siphon being full, and the air entering at, F, the residue of the water naturally iows out and empties the chamber, E and the siphon itself so that none is left to freeze.

The valve, H, is overlaid with leather at top and bottom, and thus makes a good joint,

whenever it is screwed down tight, and is' too simple to get out of order or be above the comprehension of any one.

The box which incloses this hydrant, can be taken off so that, if it requires repairs the work can be done without digging up.

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

The application and use of a siphon to hydrants, for the purposes specified, constructed and arranged substantially as above described.

JOHN HYDE.
