HYDRANT.

SPECIFICATION forming part of Letters Patent No. 785,269, dated March 21, 1905. Application filed February 17, 1904. $erial No. 193,967.

To all whom it may concern:

Be it known that I, ROBERT L. PoLLooK, a citizen of the United States, residing at Sterling, in the county of Rice and State of Kansas, have invented certain new and useful Improvements in Hydrants; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hydrants; and it consists in the novel construction. and combination of the parts hereinafter fully described and claimed. I

In the drawings, Figure l is a vertical section through a hydrant constructed according to thisinvention. Fig. 2 is a detail side view of the cap at the bottom of the hydrant. Fig. 3 is a sectional plan "iew taken on the linear a: in Fig. 1. Fig. 4 is a side view of one of the catches. Fig. 5 is a detail side view showing a catch a engaging with the projection j.

A is a ground-plate which is secured at the ground-level and provided with a projecting boss ton its underside.

C is aplug-valve casing arranged below the ground-plate, and B is a tubular distancepiece secured to the said plug-valve casing and t0 the said boss of the ground-plate and coupling the said parts rigidly together.

D is the plug-valve, which is journaled in the said plug-valve casing and provided with an angle-shaped water-passage d.

E is the inlet-passage of the plug-valve casing, which communicates with the passage (Z when the plug-valve is placed in the open position. A drain-hole e is provided in the dug-valve, which communicates with a drainhole 6 in the casing'when the plug-valve is in the closed position, so that the water is drained out of the delivery-pipe.

F is the delivery-pipe, which is secured to the upper end of the plug-valve and which passes upward through the said tubular distance-piece and ground-plate and is provided with a delivery spout or bend f at its upper end and also a suitable operating-handle F.

The plug-valve D has a screw-threaded stem G at its lower end which projects through a hole in the plug-valve casing and is provided with a nut g and a washer g, which is preferably a spring-washer of any approved make.

The plug-valve casing has a cylindrical projecting portion C at its lower end which is smaller in diameter than the main portion of the casing, so that a shoulder h is formed, and H represents two lugs which project from the said portion 0, one on each side thereof.

I is a cap which is slipped over the portion C, so as to protect the nut. This cap is provided with angle-shaped grooves din its sides, the lower portions '11 of which are inclined, so that when the said grooves are slipped over the said lugs and the cap is partially revolved by means'ot' the projection I on its side the top edge of the cap is drawn tightly against the said shoulder it. i

J isan adjustable hearing, which is screwed into the top end of the ground-plate A and provided with a projection j for revolving it. The delivery-pipe F is journaled loosely in this bearing.

K is a collar secured on the delivery-pipe F below the bearing J and provided with a ball-race la in its upper side.

K represents antifriction-balls, which run in the said race, and k is a washerplate which rests on the said balls. A washer-plate m is also arranged on the delivery-pipe in contact with the bottom end of the bearing J, and m is a spiral spring interposed between the two washer-plates k and m. The spring at presses the plug-valve into working contact with the tapered socketot' the plug-valve casing, and the pressure of the said spring is adjustedby meansof the bearing J N is a collar secured upon the pipe F above the bearing J and 71 represents two similar catches which are pivoted on pins 01 which project from the said collar. These catches are formed right and left and they rest on lugs 0, which project at the bottom edge of the collar. These catches have notches for engaging with the projection j of the adjustable bearing, and they have beveled portions 0', which enable them to engage automatically with the said projection. These catches are curved so as to fit neatly around the collar, and they operate to lock the hydrant in the opened and closed positions, respectively, of the plugvalve. These catches can be turned over backward when not required in use.

The hydrant is shown in the drawings with the plug-valve in its opened position, and the hydrant is turned around one-quarterof a revolution in either direction in order to close the said plug-valve and stop the How of water through the delivery-spout.

What I claim is In a hydrant, the combination. with a groundplate, a valve-casing, and a tubular distancepiece connecting the said casing and plate; of a valve in the said casing, a revoluble deliverypipe secured to the said valve and having a delivery-spout at its upper end, a verticallymovable bearing J in which the middle part ROBERT L.
