IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent No. 201,263, dated March 112, 1878; application filed August 23, 1877'.

To all whom it may concern:

Be it known that I, WILLIAM MCNAMARA, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in Hydrants; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the construction of hydrants; and consists in an improved construction of the valve-shell.

My device is shown by one figure in the ac- I companying drawing, which is a vertical longiwhat I call a valvebarrel, B, in which the valve operates. Directly to one side of the valve-seat, and above it, branches off the exitpassage A, which terminates with a screwsocket for attaching an exit-pipe, A. The valve-barrel B also terminates with a screwsocket, to which connects a pipe, H, which serves as a valve-stem chamber.

The valve I use is similar to the one shown in patent to O. L. Stacy, 1859, and the relation of the chambers in the shell is very much the same as in Stacys. Stacy, however, forms the seat of his valve on the end of the supplypipe; and, further, like Stacy, I use a wastepassage from chamber A through the valvebarrel, and thence out at the side; but as my hydrant is intended to be used without a box or casing (which result is accomplished by the provision made for a valve-stem pipe) and in direct contact with the earth, Ideflect this waste-passage a down the side of the shell,

and thus make a downward discharge of the waste-water. The object thus served is to pre vent the mouth of the waste becoming choked. If the shell were used inside of a casing, of course, there would be no danger of this.

Patents to Gallagher, 1873, and to Maguire, 1876, show hydrants which are similar to mine; but I believe none of these are adapted to be used buried in the earth.

It will be observed that by the use of the pipe H, screwed tightly into the valve-barrel, I am enabled to withdraw the valve and repair it with even more facility than where a casing is used, and the Waste being so fixed that the contact of the earth can result in no bad effect, my hydrant can remain buried always. All that will need repairs (the valve) can be removed with perfect ease, and can as easily be returned to its seat.

By means of these changes I believe Ihave improved the construction of hydrants.

What I claim as new is In a hydrant, the combination of the pipes A and H leading from the surface, the shell of one casting, and containing the chambers A A B, valve-seat formed by a ledge between the chambers A and A and B, and the Waste a, with its mouth deflected down the side of the shell, by which combination and construction the hydrant is adapted to be used without a surrounding casing or box, as set forth.

In testimony whereof I, the said WILLIAM MGNAMARA, have hereunto set my hand.

WILLIAM MONAMARA.
