ANTIFREEZING PUMP.

Specification of Letters Patent. Patented J 11116 26, 1917.

Application filed October 28, 1916. Serial No. 128,270.

To all whom it may concern:

Be it known that 1, JAMES H. ALEXANDER, a citizen of the United States, residing at Conquest, in the county of Kearny and State of Kansas, have invented'certain new and useful Improvements in Antifreezing be operated from above the surface of the.

ground, and which comprises few parts thereby enabling the same to be manufactured economically.

In addition to the foregoing, my invention comprehends improvements in the details of '1 construction, and arrangement of parts to be hereinafter more fully described, and

particularly pointed out in the appendedclaims.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear:

Figure 1, is a view in section of an antifreezing attachment, constructed after the manner of my invention, illustrating its application to a pump stock, and

Fig. 2, is a transverse sectional view .taken on the line 2-2 of the preceding figure.

With reference to the drawings, 1 indicates the body portion of my improvement which is preferably cylindrical, and provided with a lateral extension 2 having a semi-circular recess 3 formed in its side face. A gasket 4 is disposed in the recess. The extension is flanked at either side by attaching lugs 5, apertured to receive bolts 6, said bolts being adapted'to pass through ears or apertured lugs 7, formed upon a cap 8, having a semi-circular recess 9, de-

fining, with the recess 3 of the extension a circular aperture to receive therein the pump stock of the pump as indicated at 10. By applying nuts 11 to the bolts 6 and tightening the same, be drawn toward each other thereby closely shoulder 2,5.

the lugs and 7 may engaging the cap and extension 2 of the valve upon the pump stock.

The extension 2 is formed with a passage 12 designed for communication with an opening 13 formed or provided in the side wall of thepump stock, the opening 12 extending into the bottom portion of the valve and intersected by an opening 14 formed in the valve at right angles to said passage. The opening 14 of the valve is enlarged adjacent the lower face of the valve and internally threaded at 15 to receive a correspondingly threaded portion 16 of a valve plug 17; The valve plug is further formed with a rectangular portion 18 whereby it may be engaged by a wrench and rotated to force the plug in place within the valve.

The valve plug 17 is further formed with a central bore 19 adapted, when the plug is seated within the valve body to be disposed in alinement with the passage or opening'let of the valve body,vthe bore 19 however being slightly larger in diameter. The bore 19 of the valve plug adjacent its outer end is reduced and rounded to form a valve seat 20, and a reduced bore 21 extending therefrom.

11 valve 22 is located within the bore 19 of the valve plug, said valve being formed with a body portion rounded to conform to and engage upon'the valve seat 20, said valve being further provided with a depending reduced valve stem 23 which extends through the reduced opening 21. The opposite end of the body portion of the valve is formed with a reduced shank 24L, adapted to enter and be guided for reciprocation in the recess lei of the valve, the point of connection of said shank with the valve body providing a about the shank 24 and disposed with its opposlte end engaging the shoulder 25 and the surface of the passage 12 adjacent its point of intersection with the recess 14-. In this manner, the valve is held in close engagement with its seat, and communication of the interior of the pump stock with the atmosphere through the valve, normally disestablished.

The under side of the valve body is formed with depending spaced ears 27 adapted to support in pivotal engagement therebetween a lever 28 which extends diametrically across the lower face of the valve plug and in a position to engage the valve stem 23. Vertical oscillation of the lever is thus provided,

Acoil 26 is then embraced and lateral movement prevented through the agency of a guide 29 which depends from the lower face of the valve body, and engages the lever at either side thereof. The outer terminal of the lever 28 is connected by means of a flexible element 80 to an op erating means located above the surface of the ground, and not shown.

In use, the attachment is connected to the pump stock at a point below the frost line, and during periods of cold weather after the pump has been used, the flexible element 30 is pulled upward, whereupon the valve 22 is raised and disengaged from its seat, whereupon the column of water standing in the pump stock between the opening 13 therein and the level of the ground is permitted to flow out through the passage 12 into the bore 19 and past the valve through the passage 21 and back into the well or cistern.

Thus it will be seen that I have provided a simple attachment which may be readily secured to the pump stock, and which embodies a valve and valve seat, the parts be ing readily disassembled, and a novel means for operating the valve.

lVhile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations .thereover may be made and I therefore reserve the right and privilege of changing the form of the details of construction, or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention, or the scope of the appended claims.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent is 1. A pump attachment adapted to'be detachably secured to the pump stock andhaving a passage extending therethrough in communication with the interior of the stock, a plug detachably secured in the opposite end of the passage, said plug having a valve bore and a. valve seat, a valve in said bore, means for normally urging said valve upon its seat, and means operable from above the ground level for unseating said valve to permit drainage of the water from the pump stock.

2- A pump attachment adapted to be detachably secured to the pump stock, and having a passage extending therethrough, in communication at one end with the stock, the opposite end thereof being internally threaded, a valve plug having threaded en gagement in said end of the passage, said plug having a valve bore and a valve seat extending therethrough, a valve in said bore, a coil spring encircling the valve for retaining it upon its seat, a lever pivoted to the body portion of the attachment adapted to engage the valve, and a flexible element extending from said lever to the ground level whereby the valve may be unseated.

3. A pump attachment adapted to be detachably secured to the pump stock compris ing a body portion having a passage extending therethrough in communication at one end with the pump stock, the opposite end of the passage being internally threaded, a valve plug having threaded engagement in said threaded end of the passage, said valve plug having a bore and a reduced portion forming a valve seat, a valve movable in said bore comprising an enlarged portion adapted to conform to and engage the valve seat, a reduced valve stem at one end projecting beyond the plug, and a reduced shank at the opposite end, a coil spring encircling said shank adapted to retain the valve upon its seat, a lever pivotally mounted upon the body portion and adapted to engage the stem, and a flexible element connected with the said lever and extended above the ground level whereby the valve may be unseated to permit drainage of water from the pump stock.

In testimony whereof I afl ix my signature in presence of two witnesses.
