FIRE-HYDRANT.

specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed December Z0, 1906. Serial No. 348,774.

To all whom t may concern:

Be it known that I, FRANK V. CARMAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Fire-I-Iydrants, 0f which the following is a specification.

My invention relates to the class of hydrants, especially intended for lire protection.

The object of my invention is to provide a fire-hydrant which is adapted to be, practically, instantaneously opened by raising the nozzle, the latter being adapted to be elevated to any angle and turned in any direction.

To this end my invention consists in the connection with a normally open supply, of a nozzle with a suitable valve-structure adapted to be opened and closed by swinging the nozzle, suitable interposed joints to enable the nozzle to be elevated to any angle and turned in any direction, and suitable controlling means for said valve and joints, all as I shall hereinafter fully describe, by reference to the accompanying drawings, in which,

Figure 1 is a vertical section of my lire-hydrant. Fig. 2 is a face view of the nozzle-valve-casting. Fig. 3 is a face view of the valve-seat-casting. Fig. 4 is a detail elevation of the pawl and ratchet control of the horizontally rotating union joint.

The stand pipe 1 has an elbow 2 to which, by a suitable connection 3 is coupled the supply valve 4, which is to be left open at all times, except when repairs are made on the hydrant, such as packing, etc.

To a connection 5 from the supply valve 4 is fitted a union joint which permits horizontal movement of the hydrant. This joint comprises a casting 6 screwed to the connection 5, a flanged elbow 7 seated in the top of the casting G with intervening packing 8, and a cap ring 9 bolted to the casting, with intervening ballbearings 10 and track-ring 11 between itself and the flange of the elbow 7. By this connection the elbow 7 may be rotated in a horizontal plane. The elbow 7 at its other end is fitted with another joint which will permit movement of the hydrant in a vertical plane. This joint is composed of a valve-seat-casting 12, to the end of which is fitted, with packing 13, a flanged nipple 14 screwed on the elbow 7: a cap-ring l5 bolted to the casting confines the nipple against a ball-bearing 16 with track-ring 17. By this connection the valve-seat-casting 12 may rotate in a vertical plane on the nipple 14.

18 is the nozzle fitted to an elbow 19 which is screwed to the nozzle-valve-casting 20. This casting is seated against the face of the valve-seat-casting 12, and is held to place by a cap-ring 2l, with intervening ballbearing 22 and track-ring 23. Thus, the nozzle may turn, with its valve-casting 2O in a vertical plane, on the face of the valve-seat-casting.

The valve-seat-casting 12 is provided with opposite ports 24, as seen in Fig. 3, and the nozzle-valve-casting is provided with opposite ports 25, as seen in Fig. 2.

When the nozzle is hanging down, as shown in Fig. 1, the ports of the two castings do not register, and the water is shut off. But, when the nozzle is swung up-l wardly the ports will register and the water will fiow. On account of the shape and dimensions of these ports, it will be seen that they will register, practically, instantaneously by moving the nozzle.

The vertical swing of the nozzle. to reach the full alinement of the ports is limited and defined by studs 26 projecting from the face of the valve-seat-casting, playing in grooves 27 in the face of the nozzle-valvecasting 20. i

The several limitations and control of the movements of the hydrant are as follows. In order to hold the valve open, when the hydrant is in use, there is a sliding lock-bolt 28 fitted to the cap-ring 21, which is adapted to engage, either by gravity or otherwise, with a hole 29 in the nozzle-valve-easting 20, when said casting is turned to fully register the ports. In order to lock the joint between theV elbow 7 and the valveseat-casting l2 against movement while the nozzle is being swung up to open the ports, and then to relieve said jointto enable the nozzle to be turned to an angle above the horizontal while the ports are open, there is a sliding lock-bolt 30 fitted to the cap-ring l5 which is adapted to engage a hole 31 in the nipple 14. In order to control the horizontally rotating joint between the casting 6 and the elbow 7,. there is a two-legged safety pawl 32 pivotedto the elbow 7 and adapted to oppositely engage a ratchet 33 on the cap-ring 9, the movement of the pawl to either side permitting movement of the joint in one direction while holding it against movement in the other direction, as is shown in Fig. 4. This device prevents the hydrant from back movement caused by pressure of water issuing from the nozzle tip.

34 is a handle attached to the nozzle-elbow 19,t0 assist in operating the nozzle.

The operation of the hydrant is as followszThe normal position, when not in use, is shown in Fig. 1, the supply valve 4 being open, and the water shut off at the valve joint formed by the

castings

12 and 20. To use the hydrant, the nozzle is first lifted in a vertical are, until the

ports

24 and 25 register7 and the water immediately issues. This open position is maintained by the lock-bolt 28 dropping, or being otherwise moved, to engage the hole 29 in the casting 20. Then, to elevate the nozzle still more, the lock-bolt A30 is lifted from its engagement with the hole 31, whereby the valve-seat-casting 12 is free to turn on the nipple 14. To swing the nozzle, thus elevated, to any position horizontally, the device is now turned on the union joint formed between the casting Gand the elbow 7;

and, finally7 the pawl 32 is turned to the proper side to engage the ratchet 33, and thus to hold said joint against back pressure caused by the Water issuing from the nozzle tip. Thus, every possible position may be reached by the nozzle, and its movements properly controlled.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l, A fire-hydrant comprising a universally jointed connection from a normally open supply; a nozzle; a rotatable coupling joining the nozzle to said connection; and a valve-structure included in said coupling and operated by the movement of the nozzle to open and close the fluid communication between said connection and nozzle.
