IMPROVEMENT lN HYDRANTS.

Specification forming part of Letters Patent No. 177,860, dated May 23, 1876 application filed April 1, 1876.

To all whom it may concern Be it known that I, THOMAS MAGUIRE, of Port Jervis, in the county of Orange and State of New York, have invented a new and valuable Improvement in Hydrants; and I do hereby declare that the following is a full,

clear, and exact description of the construetion and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters I and figures of reference marked thereon.

Figure l of the drawings is a representation bf a plan view of my hydrant, and Fig. 2 is a longitudinal vertical sectional view of the same.. Fig. 3 is a .plan view of a modification, and Fig. 4 is a longitudinal vertical section thereof.

The nature of my invention consists in the construction and arrangement of a hydrantvalve, seat, cylinder, and spout, with the valve-stem or plunger, as will be hereinafter more fully set forth.

In the annexed drawing, A represents the barrel or cylinder of the hydrant, with side spout'B. Below the spout in the barrel A is formed the valveseat a, upon which is placed a rubber ball-valve, (3. Over this ball-valve is placed-a cup, D, formed on or attached to the lower end of a stem or rod, E, which extends up through the barrel A to and. above the ground, where it is to be operated by a screw or lever in any suitable manner. At a point on the rod E above the entrance to the spout B is formed or attached a plunger, H, with cup-shapedleather packing I, held over the same with a nut, J.

By raising the rod E and cup D a certain distance the water lifts the valve 0 sufficiently to pass by the same, and up andout through the spout B, and, 'by lowering the cup, the valve is again forced to its seat to shut off the water.

The leather packing- I on the plunger H makes the barrel tight, so that the water cannot pass up through the same, and yet allows the rod to move freely up and down.

When the ball 0 wears so as to be useless, the rod and cup are raised to bring the cup above the entrance to the spout B, when the water will carry out the ball through the spout. The cup is then lowered onto the seat a, and may, if necessary, be used temporarily without the ball-valve. For this purpose,

there is a groove inthe edge of the cup D,

which is filled with soft metal,-as shown at b,

so as to make a joint with the seat. When it is then desired to insert a new valve the wa-' ter is turned off, the cup D raised, and the valve dropped in through thespout B, which valve then falls down on its seat. The cup is then lowered, and the water may be turned on again.

The leather packing I can easily be renewed when worn out, by simply drawing out the rod E, the water being, of course, first turned off.

Instead of a separate ball-valve, I may use a rubber head, 0, drawn overa knob, D, on

the end of the rod E. i

The hydrant should, of course, be provided with a suitable vent to draw off the water standing therein, and prevent freezing.

Hydrants constructed in this manner are simple, durable, cheap,and not liable to get out of order; and when necessary to repair them, it can be done without the trouble and expense of digging down to them.

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

In a hydrant, the barrel A,-having valveseat a and spout B in close proximity to said seat, in combination with the ball-valve 0, rod E, cup D, and piston H I J, whereby a flow of water is always secured to the spout when the valve is open, and at the same time, when desired, the ball may be removed through the spout by the pressureof the water without detaching the parts, substantially as described, and for the purpose set forth.

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

THOMAS MAGUIRE.
