PUPPET-VALVE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

To all whom it mag/,concern- Be it known that I, TIMOTHY STE-Brems, a citizen of the United States, and a resident'of Davenport, in the county of Scott and State of Iowa, have invented certain new yand useful Improvements in Puppet-Valves, of which the following is afull, clear, and exact description.

The object of'my invention is to provide a puppet-valve for pumps whose movements are guided by a retainingv device the weight of which keeps it in proper position and which does not interfere with the valve when lowered into position in the well or when removed from its seat for purposes of repair or replacement. This I accomplish by means hereinafter fully described and as. particularly pointed out in the claims.

In the drawings, Figure l is a longitudinal central section of a well-pipe in the vicinity of the foot-valve, showing my improvements applied thereto. Fig. 2 is a perspective view of the guide-cage of my invention removed. from the well. Fig. 3 is a view similar to that shown in Fig. l, showing a modified form of a puppet-valve which may be used in connection with my invention.

In the drawings, A represents a portion of the cylinder above the coupling B, containing the valve-seat of the puppet-valve of the pump, and C represents a portion of the suction-pipe below said coupling. About the center of length of the coupling B the passage therethrough is restricted by the inwardly-projecting annular flange c, and the restricted passage or opening is screw-threaded and has a valve-seat D tapped onto same. The upper portion l) of this valve-seat D, which extends above the upwardly-flared marginal edges of the opening in which it is placed, is slightly less in diameter than the lower portion thereof and is provided with an outwardlyprojecting circumferential flange c, which when the valve-seat is secured in place rests upon the upper flared edges of said fiange a. The puppet-valve E, engaging the upper edges of the valve-seat, is preferably circular, and I prefer to face the lower portion e thereof coming in contact with the valve-seat with leather or other suitable material, into which the upper edges of the valve-seat can make ,an impression. Projecting centrally upward from the valve E is a stud or guide-spindle g, the upper portion of which is Screw-threaded, which has a reciprocal play in the guide-.boss F. This uide-boss is provided with a series of equiistant corresponding legs ff, :the lower eX- tremities of which are `cast in one piece with or otherwise secured to a ring G, the inner circumference of which latter is of such diameter that it can fit snuOly around and inclose the upper portion b ofD the valve-seat D and rest upon the fiange c thereof. I prefer to make the thickness of this ring in a vertical direction such that the inner upper angle of the same will, when the rinfT is resting `upon the flange c, be in the same plane as thev upper edge of the valve-seat, and I prefer to bevel or incline the upper edges of the ring upward and outward from said upper inner angle thereof, as shown.v If desired, the spindle g may be alone depended upon to guide the vertical reciprocal movements of the valve E onto and off of tne valve-seat. This movement can, however, be further assured by making the distance 'between the inner vertical edges of the opposite legsf of the valvecage substantially correspond to the diameter of the valve.

In operation when the valve E is lifted by the action of the operative parts of the pump above it the water will flow up between the under surface of the valve-seat and into the cylinder above the valve and will come in contact with the upper beveled edges of the ring Gr and have a tendency to force it downward. This action of the water, however, merely supplements the weight of the ring G and other parts of the valve-cage of which it is a part to retain the valve-cage in its proper position, as shown in Fig. l of the drawings.

In Fig. 3 of the drawings I show a modified form of a puppet-valve in conjunction with the other parts of my invention, which latter, comprising the valve-seat H and the valvecage I, are substantially the same as shown in Fig. 1 of the drawings. The upper structure of this modified puppet-valve J is the same as that shown in said Fig. l, the only difference being that the lower face of the valve is provided with an interiorly-threaded central opening h, and a leather washer is clamped against the under surface of the valve by a plate K of slightly less diameter than the valve-opening. Plate K is provided with an upwardly-projecting stud 7c, which extends through the central opening TOC in washer j and is tapped into opening h of the valve J. This plate K is provided with a series of downwardly-projecting equidistant corresponding wings L, that converge toward and merge near or at their axis, which alines with the axis of the valve-spindle. These wings assist in directing the movement of the valve J and can be made as shown in the drawings or in any other suitable manner.

What I claim as new is- 1. Ina pump, a removable puppet-valve having a vertical stud arising therefrom and a valve-seat therefor having the exterior of its upper yannular portion that is engaged by the valve-cage provided with a smooth unbroken surface, in combination with a valvecage comprising a perforated guide-boss engaged by said stud, a series of legs extending outwardly and downwardly therefrom and a ring to which the lower extremities of said legs are connected, which has its upper edge beveled and the portion engaging the valveseat having a smooth surface7 and which ring rests and is held upon the valve-seat outside the portion engaged by the valve by the weight of said valve-cage.

2. In a pump, a removable puppet-valve having a vertical stud arising therefrom and a valve-seat therefor the exterior of the upper annular portion of which is provided with a smooth surface, in combination with a valvecage comprising a perforated guide-boss engaged by said stud, a series of legs extending outwardly and downwardly therefrom and a ring to which the lower extremities of said legs are connected, which has its upper edges beveled, and which rests and is held upon the valve-seat flange by the weight of said valvecage, the surface of the ring that engages the valve-seat being smooth and unbroken.

In testimony whereof I have hereunto set my hand this 25th day of July, A. D. 1905.

TIMOTHY STEBBINS.
