VALVE.

Application filedjlarch 5, 1920. Serial No. 363,605.-

To all whom it may concern:

' Be it known that I, Ln RoY G. VVr BER, a citizen of the United States, and residing at Sequim, in the county of Clallam and State of Vashington, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to improvements in valves primarily employed for draining pipes in pumps. The prime object of the invention is to provide a valve and means associated therewith for quickly and conveniently draining pipes out of reach in a well to prevent the water in the freezing zone freezing within the pipe. The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and claimed.

In the drawing:

Figure 1 is a sectional view of a well showing my improved valve attached to a pump pipe.

Fig. 2 is an enlarged detail view of my improved valve in a closed position.

-eferring now more particularly to the drawings, 1 indicates a pump standard supported by a well platform 2; 4 a pipe extending downwardly from the pump stand-v ard and into the water in the well 5; 7 1ndicates a pump cylinder in the feed pipe 4; 8 a piston slidably mounted within the cylinder 7; and 9 indicates a rod connecting the piston 8 and the handle of the pump.

The parts thus far described are of usual construction, and form no specific part of my invention except to illustrate the application of the improvement.

10 indicates a threaded coupling in the pipe 4, just above the cylinder 7, and in the horizontal portion 11 of the coupling is threaded a plug 12., The-head of the plug 12, has attached to it an arm 13, and extending through the same and the head is an axially disposed opening 12 and below same is a drain opening 14:. The arm13 extends up beyond the coupling and its upper end is bifurcated to receive a guide pulley 15. The lower portion of the arm depends below the coupling as shown at 18. Pivoted to the Specification of Letters Patent.

around the guide pulley 15, and thence through an opening in the platform to be in W convenient reach of an operator.

A valve 23, seats against the inner end of the plug 12, and from said valve extends a stem 25, which passes through the openings 12- and 20. Studs 26 and 27, extend from the stem to confine the lever to permit of the latter operating the valve, a coil spring 28 on the stem is interposed between the arm 13 and the lever 19, to normally hold the valve in closed position.

In operation, the pump water usually ac cumulates in the pipe above the coupling and in cold weather freezes and serious results follow. According to my invention this difficulty can be conveniently overcome by simply pulling'on the rope. This forces the lever 19 toward the arm 13, and through the medium of the stud 26.

The spring is compressed, and the valve- 23 is removed from its seatagainst the end of the plug 11, and water above the coupling will drain through the opening 14 and into the well. After the water has been drained, and pull on the rope is released, the spring quickly restores the parts to normal position and the valve closed. 7

The invention is extremely simple in construction and is effective in operation, and the parts are so arranged as to avoid getting out of order.

What I claim is: y,

1. In combination, a water pipe, a T coupling connected to the water "pipe, a hollow plug seated in the horizontal portion of the T coupling and formed with a centrally disposed opening and a drain opening below the same, an arm extending above and below the T coupling, a guide at the upper end of the arm, a valve normally seated against the inner end of the hollow plug, a stem extending through the centrally disposed opennected to the upper end of the lever and passing over the guide at the upper end of the arm, whereby to operate the lever and unseat the valve.

2. In combination, a water pipe, a T coupling in said pipe formed-with a drain open ing, a valve for closing a lateral opening in In testimony whereof I aflix my signature the T cgupling, an arlln secureil tlo 1(sne end in the presem'e of two Witnesses. of the cou lin at ever a in etween one end of th le e r and the arm, a c0nnec LE ROY (L W 5 tion between the valve and the opening, and Witnesses:
