PHILIP ELEY, OF BAYONNE, NEW JERSEY.

SPECIFICATION forming part of Letters Patent No. 507,651 dated October 31, 1893.

Application filed December 3| 1892. ,Serial No. 453,949. (No model.)

To all whom it may concern:

Be it known that I, PHILIP ELEY, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New J ersey, have invented certain new and useful Improvements in Hydrants for Water-Mains, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

My present invention involves a new and useful hydrant or fire plug for water mains, the improvements in which are directed mainly to providing for a free and unobstructed flow of water from the main to the nozzle. In hydrants as heretofore constructed this feature has either been wholly disregarded or subordinated to such an extent in the construction and disposition of the valve and attendant parts, that a considerable difference of pressure was noticeable between the main at the point of connection and the nozzle or vent of the hydrant occasioned by the back pressure and eddying of the water in its course into and through the hydrant, by reason of the presence of sharp angles in its path or of obstructions such as the valve and its connected parts. My object is to overcome this, and to provide a valve which when open will present to the inflowing stream of water an inclined surface upon which the stream will impinge, and by which it will be deflected toward the nozzle.

To this end I have devised a hydrant in which the valve has a plane or flat surface that is held firmly against the opening from the main, when the hydrant is closed, but which is caused, in receding from such opening, to assume an angular position, so as to present to the water an inclined or upwardly deflecting surface.

This improvement may be carried out by mechanical devices of various kinds, but in the accompanying drawings I have illustrated only those which I regard as of the most useful, and practicable character, and to theseI now refer in explaining more in detail the nature of the invention.

Figure 1 is a vertical central section of a fire-plug or hydrant constructed according to my invention. Fig. 2 is a similar view of the lower portion of the same with the valve closed. Fig. 3 is a vertical section of the parts exhibited in Fig. 2 on the line ma; of said figure. Fig. is a cross-section of hydrant casing. Fig. 5 is a vertical sectional view of a modification.

The hydrant case is composed, preferably, of a cylindrical portion A having a rectangular chamber A extending along its full length; a rectangular base or valve chamber B, and a cap or cover (3. The valve chamber is provided with the usual hub D for the spigot of a main or branch, and in the orifice or inlet is inserted a valve ring or facing E of metal properly turned or ground. The valve proper is composed of an inner or similar bodyF provided with lugs or projections G on its sides. A face plate H is used with the valve body and is formed with two downwardly'projecting flanges b, b, the upper one of which passes over and engages the upper edge of the body F and the under one enters a groove 0 in the said body when the plate is in position. This plate has a ringI by means of which it maybe lifted 0% from the main valve body byahooked rod introduced down I through the hydrant in case it may be necessary to remove it for repair. My intention is to provide a rubber or other like facing for the plate which in time may become worn and require renewal. To the blockF constituting the valve body is pivotally connected one end of a link M, the other end of which is pivotally joined with a stem N and block 0 that slides over the surface of a plate P in face of and preferably inclined toward the inlet from the main.

The lugs G extend between projections K, L, which latter form guides or ways by which the movement of the valve is directed. The paths or ways thus formed are for a certain distance at right angles to the plane of the valve seat formed by the ring E, and then slope downward, so that if the valve be drawn away from its seat by depressing the rod N,

it willbe gradually tilted away from said seat. In order that the lugs G may more readilyfollow the angle of the ways on which they travel, they are scored on their under sides as shown.

The upper end of the rod N is threadedand engages with a turn-buckle R. A stem S passes through a stuffing-box in the cap of the hydrant and is threaded to engage with the turn-buckle. Normally the rod N is drawn up by the stem S and buckle R in about the position shown in Fig.2. The water is then shut off, since by the toggle action of the link M the valve is forced tightly up against the face E. hen in this position the block 0 uncovers a small escape vent T through which the water in the plug flows off.

Then it is desired to draw water from the hydrantthe nozzle is opened in the usual Way and by a wrench the stem S is turned. As the turn-buckle R is prevented by its shape and that of the chamber in which it is contained from turning, it is forced downward bythe unscrewingof the stem S. This forces down the rod N which draws back and tilts the valve as above described.

Vhen the valve is open the vent T is closed, and in order to insure the proper closing of the latter I provide a lug V between which and the plate P the block 0 is jammed by the depression of the rod N.

As a modification of a valve which shall be capable of movement bodily from the port or inlet and also of assuming an angular posit1on when so removed, I may use the device shown in Fig. 5. In this all the parts are the same as in the previous figures, except the means for supporting the valve. For this I provide studs X, and form the valve body with hooks WV or slots of sufficient depth to permit of the required movements of the valve without its becoming detached.

I-Iydrants constructed by me as above described, have proved, after extensive and severe tests, to possess great advantages over the usual forms.

The feature of a supplemental chamber containing the valve rod and leaving the stand pipe entirely free for the unobstructed passage of the water, is a particularly desirable one, While the diminution of pressure between the main pipe and the nozzle is prevented to a very large extent by the deflection of the water up into this channel.

Another advantage is secured by the employment of the swivel nut as the rod N is thus relieved of all torsional strain, such as it would otherwise be subjected to if the nut were dispensed with, or if a nut were used and the rod N secured rigidly to it.

\Vhat I claim as my invention is- 1. In a fire plug or hydrant,the combination of a valve body having a plane surface presented to the inlet port, a vertically adjustable stem or red, connections between the same and the valve body, and supports or guides for the valve body by which on the depression of the rod and movement of the valve body the latter will first recede from and then incline with respect to the valve port,

2. In a hydrant, the combination of a valve body having a plane surface presented to the inlet port, a vertically adjustable valve stem or rod, a link pivoted to the said valve body and stem and guides orsupports for the valve body which direct its movement bodily to and from the port and tilt or incline it with respect thereto.

3. In a hydrant, the combination of a valve body, guides for directing the movement of the same, said guides being at right angles to the plane of the valve port and then -inclined downward therefrom, a block adapted to slide vertically over a surface in front of the port, a link connecting the valve body and block and a vertically adjustable valve stem or rod for raising or lowering the said block.

4. The combination, in a hydrant, of a valve body, a block adapted to slide vertically over the wall of the valve chamber in front of the valve port, said wall being provided with a vent hole which is covered and closed by the block when the valve is open, but uncovered and open when the valve is closed, a link connecting the block and valve body, and a valve stem for raising and lowering the block.

5. The combination, in a hydrant, of a valve body, a block adapted to slide vertically over PHILIP ELEY.

\Vituesses:
