Specification of Letters Patent.

Application filed November 27, 1914. Serial No. 874,193.

To all whom it may concern:

Be it known that I, GEORGE N. FRAZER, a citizen of the United States, and a resident of Eugene, in the county of Lane and State of Gregon, have made certain new and useful Improvements in Hydrants, of which the following is a specification.

My invention is an improvement in hydrants and has for its object to provide a cheap, simple and durable hydrant, wherein a casing is provided, having a main inlet valve at one end, capable of being closed by a valve which is mounted to swing into and out of closed position, and wherein the valve is connected to its operating mechanism by hollow trunnions, so arrangedthat when the valve is closed the bore of-the trunnions will register with a drain port in the casing to permit the casing to be drained of all water that may be therein when the valve is closed, and wherein the opening of the valve will move the bore of the trunnions out of register with the drain port to close the same to prevent leakage.

In the drawings, Figure 1 is a side view of the improved hydrant with parts in section, Fig. 2 is a top plan view of the lower section of the casing.

In the embodiment of the invention shown in Figs. 1 and 2 the hydrant consists of a sectional casing composed of a main body section 1 having the usual discharge outlet 2. a base or inlet section 3, and a cover l. The

base or inlet section 3 of the hydrant is provided with a lateral inlet 6 and the said section and the body section 1 have marginal flanges 7 at their meeting ends through which are passed bolts and nuts 8 to securely connect the three sections together.

It will be understood that suitable packing rings may be arranged between the sections if desired. The discharge outlet 2 is normally closed by a plug 9 which may be threaded into the outlet or otherwise connected to the body section by a chain 10, or other flexible connection. At the ground line the section 1 has an annular rib 11. and

the lower end of the base or inlet section 3 is closed, the lateral inlet 6 bein adapted for engagement by an elbow 12.

It will be noted from an inspection of Fig. 2 that at the inlet of the section 3 a seat is provided for the, valve to be presently described. The seat is formed by the inner end of theelbow, the elbow having an annular flange 13 which fits against the outer face of rubber or the like for insuring a perfect fit against the seat. An arm 17 extends radially from the valve at the lower side thereof downwardly and inwardly and the arm is hinged to the casing at its lower end in a manner to be presently described.

It will be noticed that that portion of the section 3 in which is arranged the port 6 faces downwardly and outwardly, so that the seat formed by the inner end of the elbow 12 faces inwardly and upwardly and the valve 15 closes down onto the seat. A ring 18 of brass or .the like is fitted against the inner end of the elbow 12 to form a seat for engagement by the facing 16 of the valve and the trunnion 19, at the lower end of the arm 17, is hollow as shown at 20. A radial passage 21 leads from the hollow or bore of the trunnion and this passage is arranged to register with an opening 22 in the casing at this point. When these passages 21 and 22 are in register, the water may flow from the casing. of the hydrant out through the drain passage 22 to free the hydrant from water. These passages register only when the valve 15 is closed against its seat. lVhen the valve is open the passage 21 is out of register with the passage to prevent drainage through the said passage.

The valve is opened and closed by means of a link or rod 23. The rod 28 extends upwardly through the cover of the casing and at its lower end the rod is connected to a pair of rollers 24. From an inspection of Fig. 3 it will be seen that the section 3 of the casing has a plane side opposite the inlet end of the elbow 12 and facing the said inlet. The inner face 25 of this surface provides a track uponwhich the rollers 24 may be moved. Bibs 26 are arranged at each side of the section 3, the said ribs being in the same plane and acting as guides for preventing movement of the roller away from the surface or track 25. The ribs exa bearing diametrically of the rear face of the valve by means of links 28.

The lower end of the rod 23 is connected to the rollers and between the same by a connector 29 of bronze or the like and it will be evident that when the rod is moved downward the valve 15 will swing on the arm 17 against the seat 18. When the rod is moved upward the valve will swing away from the seat and toward the surface 25 of the casing. A plate 30 is arranged between the cover 4 and the body section 1 of the hydrant, the plate resting upon the upper end of the body section and the cover resting upon the upper face of the plate. The plate is provided with an opening through which extends a nut 31 connected with the rod, and a packing box 32 is provided at the opening and encircling the nut, the said box being adapted to receive a packing which is compressed on the nut by a packing nut 33 threaded into the packing box. The lower end of the nut is connected to the upper end of the rod and the lower end of the rod is connected to the upper end of the connector 29 by means of taper pins 34:, the said pins passing through the connector or the nut and the rod.

The nut 31 is in effect an internally threaded socket and the upper end thereof fits against the inner face of the cover. A set screw 35 having a head polygonal in cross section is engaged with the nut, the said screw passing through an opening in the cover 4:. A collar 36 is pinned or otherwise secured to the set screw outside of the casing and the set screw is preferably of steel, having a thread with a pitch of three turns to the inch, and the thread is preferably double and square. The upper end of the nut is provided with a collar 37 secured thereto in any manner and the two collars 36-37 hold the set screw in place and take the thrust of the pressure of the water when the valve is closed.

In operation with the parts in the position of Fig. 2, to close the valve the set screw 35 is turned in a direction to force the nut downwardly. The nut in turn forces the rod 23 downward and the rollers 21 move downward, pushing the valve 15 toward the seat 18 and this operation is continued until the valve is tightly seated. When so seated the passage 21 registers with the passage 22 and the hydrant casing will quickly be drained. Since the outlet or discharge opening of the casing is below the plate 30 and since the said plate forms a partition between the body of the casing and the interior of the cover the water never touches the screw threads of the nut or the set screw, so that these parts cannot rust or become jammed for any reason. A little oil now and then is sufficient to thoroughly lubricate the parts. To open the valve the set screw is turned in a direction to lift the nut, and the nut in turn lifts the valve into out.

It will be understood that the trunnion or pivotal connection 19 upon which the valve swings is merely a cylindrical or spherical body which fits within a' similarly shaped socket.
