.To @ZZ whom it may concern.- Y A Be it known that I, STANLEY B. LAFFERTY, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, administrator of the estate of RB- ERT M. LAFFERTY, deceased, late of said city, do hereby declare that said ROBERT M. LAE- FERTY did invent certain new and useful Improvements in Puppet-Valves for Pumps, of 1o which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This application constitutes a division of i5 the original application of said ROBERT M.

LAFFERTY, deceased, for the same subjectmatter, which was led December 30,1887, and serially numbered 259,366; and the invention herein described relates to check or puppet zo valves for tubular well-pumps, and is so constructed that its voluntary displacement from its seat is effectually prevented, and yet it can be easily lifted out of the well-tube when so de,-v sired without the-aid of outside appliances, z 5 substantially as hereinafter fully described, and as illustrated in the drawings, in which- Figure l shows a vertical central section o f a portion ofa tubular deep-well pump having the improved valve seated therein. Fig. 2 is 3o a vertical central section through said valve. Fig. 3 is a similar section through a modified form of the same, and Fig. Itis aplanvview of the valve-seat.

Referringto the drawings, A represents a circular or other desirable shaped plate, composing the body of the valve, and it is provided with a central post B, projecting verti-f cally therefrom. Secured concentricaliy upon said bolt B, immediately next the plate, by

4o means of a nut C, is apacking-ring or disk D. The diameter of disk D is preferably greater than plate A, and its projecting edges are adapted to rest upon the annular edges of the valve seat or ring F. Ring F rests upon the inner annular ledge b of the well-pipe, as shown, and constitutes the valve-seat. It is provided with a flange extending vertically downward from its inner edges, which is concentric with said well-pipe 4valve from its seat.

.loops) are secured to said plate A by means of staples c at such distance from the center" thereof that they come Within the radius of the contracted opening of the valveseat. From the point where said yokes leave the plate A they pursue a straight downward course a suitable distance, whereupon they are bent outward radially to form the shoulders e; It is thus obvious that the vertical movement of the valve is limited to the distance between the plateA and said shoulders e, and it is equally apparent that this distance must be sufficient to permit the water to pass up through the contracted opening of the valve-seat.

The staples c are preferably cast integral .with'the plate A, and the ends of the loops or yokes E are made to pass through said staples by being bent parallel to the plane of the under surface of said plate and are prevented from withdrawing by having their extremities bent downward at right angles to said plate, substantially as shown. The bends of the yokes are preferably passed through suitable openings in the lower end of a suitable stud I, extending vertically and centrally down from said plate.

Theyokes being made of spring-wire can be easily forced down through the valve-seat opening when it is desired to seat the same. When once in place, however, they cannot be forced off their seats, except by the application of more power than is exerted by the up-,rush of water. Sufficient manual or external-power must be exerted to cause the yokes, cr rather the upper ends of them, to move inward toward the center of the plate A. To provide for this application of power, a nut G is made, which yis preferably made integral with the plunger X, and which, by screwing it down onto the upper screw-threaded end of post B, gets a good purchase or hold on the valve, and when it is lifted out of the well removes the To prevent the valve S Masse from turning while the nut G is being screwed onto the post B, ring F is provided with one or more inwardly-projecting lugs ff, which, when the valve begins to rotate, engages one of the yokes and prevents further rotation thereof.

In Fig. 3 there is substituted, in lieu of each yoke, two spring-wires g, each of which depends down from plate A in substantially the same manner as the ends of yokes E and curve downward from the shoulders h thereof in toward each other. Just before these wires touch, however, they bend centrally upward into a pocket in the lower end ofthe stud H, depending centrally downward from Said plate A. The upper ends of these springs g are immovably secured to the plate, so that, instead of said upper ends moving when it is desired to insert the valve in place, or vwhen it is desired to remove the same, similar to the upper ends of the yokes E hereinbefore described, the lower ends, guided by the pocket, are made to move downward. However, so far as the spirit of this invention is concerned, it makes no difference whether the upper ends or thellower ends of the yokes or springs g are made to move, so long as the shoulder e or h is caused to move inward dur'- ing the insertion in or removal of the Valve from the valve-seat.

What is claimed as new isl. In a puppet valve, the combination with the valve seat, of the plate A, springs secured to and depending down therefrom a given distance where they are radially bent outward to form shoulders, and acentral stud extending from said plate to -which the lower portions of said spring are connected, as set forth.

2. The combination with a tubular wellpipe having a valve seat therein, substantially as specified, of a valve, having a plate A with a central `stud depending down therefrom,

and yokes or springs connected to and de- STANLEY B. LAFFERTY, Administrator of R. M. Layjferty, deceased.
