TIMOTHY STEBBINS, OF DAVENPORT, IOWA, ASSIGNOR TO RED JACKET MANUFACTURING COMPANY, OF DAVENPORT, IOWA, A CORPORA- TION OF IOWA.

PUPPET-VALVE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

T0 @ZZ whom it may concern:

Be it known that I, TIMOTHY STEBBINS, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Puppet-Valves, of which the following is a full, clear, and exact specification.

My invention relates to puppet-valves for pumps; and its object is to provide means for retaining the said valve in operative relation to its seat in such manner that both the valve and said retaining means can be inserted down into the well from above round and secured in place or removed thereirom for repairs, according as desired; and its object is also to provide a valve which will lift from or drop into its seat without the possibility of binding either in its open or shut position. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical section of a coupling in which the valve-seat of the puppet-valve is located, showing my improvements applied thereto. Fig. 2 is a transverse section thereof, taken on dotted line 2 2, Fig.' l. Fig. 3 is a side view of a -modified form of valve capable of use in connection with said retaining means. Fig. 4 is a -transverse section taken on dotted line 4 4, Fig. 3, looking in the direction of the arrows.

Referring to the drawings, A represents a coupling which connects the sections of thewell-pipe a above the puppet-valve in which the lower cylinder of the pump is located and the well-pipe below the same. About its center of length this coupling is provided with an inwardly-projecting flange if, which restricts the bore of the well and has the valve-seat B screwed into the restricted opening made thereby. This valve-seat is cylindrical from its lower to Vnear its upper end b, which latter extends above the iiange 7c and is made thicker, so as to further reduce the valve-opening. The outer circumference of this upwardly-extending portion b is undercut, substantially as shown. The valve engaging this seat B comprises a circular plate c of a diameter sufficient to cover said seat and has its under side faced with leather d or other suitable material. Projecting centrally upward from plate c is a stud e, whose lower cylindrical portion is smooth and whose upper portion is screw-threaded. This stud e projects up throughv a suitable central guide opening in the boss C of a spider, which has three or more corresponding equidistant inverted L -shaped legs DD, the inner edges of which serve as guides for the circumferential edges of the plate c of the valve and, together with the engagement of the guide-opening of the boss of the spider by the stud e thereof, insures the movement of the valve in a vertical plane to and from the valve-seat. The inner surfaces or edges of the legs D are provided with a convexed double bevel forming a kind of foot F, and as said legs are cast of a metal having a certain degree of elasticity when the valve is lowered by some means, such as the lower end of the plunger or a pipe into whose lower extremity it is screwed until it closes the valve-opening, the extremities of the legs snap over the outer inverted beveled edge of the valve-seat and are retained thereby sufliciently tight to hold the 'spider in such position as to confine the valve and guide the reciprocations of the same in the manner hereinbefore described.

v In view of the fact that when it is desired to release the valve after it has been inserted in place it is necessary tounscrew the means by which it was lowered from 'stud e, and it is desirable to prevent the spider from revolving with'it I provide the outer circumference of the valve-seat with a stop-lug I, which one of the legs of the spider will engage and prevent further revolution thereof should the friction of the valve have a tendency'to turn it.

In Fig. 3 of the drawings I showa modified form of the valve. I In this modification the plate f is constructed the same as plate c, hereinbefore referred to, except that it is provided with a central screw threaded opening G, which extends longitudinally up into its stud g. A rubber packing-ring 7L 1s placed a ainst and is secured to the under side of p ate f and is secured thereto by a disk PI, that has a screw-threaded stud H', which screws up into the screwthreaded central opening G in plate f until said packing-ring is clamped between it and said plate f. Projecting downward from this disk are wings y', which extend in planes at right angles to each other and intersect at a point in alinement with the axis of stud H. These IOO wings extend down through the valve and serve as an additional means to direct the movements of the valve.

What I claim as new is 1. In a well the combination with a valveseat having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider engaged by said stud and having legs that spread over and inclose said valve and are provided with enlarged lower ends that engage the undercut portion of the valve-seat whereby said spider is removably retained in proper position to confine and guide said valve.

2. In av well the combination with a valve- Seat having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider having a perforated boss engaged by said stud and having legs that spread over and inclose said valve and are provided with enlarged lower ends that engage the undercut portion of the valveseat whereby said spider is removably retained in proper position to confine and guide said valve.

8. In a well the combination with a valveseat having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider engaged by said lstud and having legs that spread over and inclose said valve and have their extremities .provided with enlargements that interlock with the undercut portion of said valve-seat.

4;. In a well the combination with a valveseat having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider having a perforated boss engaged by said stud and having legs that spread over and inclose said valve and have their extremities provided with enlargements that removably interlock with the undercut portion of the valve-seat.

5. In a well the combination with a valvesea-t having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider engaged by said stud and having elastic legs that spread over and inclose said valve and are provided with enlarged lower ends that engage the undercut portion of the valve-seat whereby said spider is removably retained in proper posiltion to confine and guide said valve.

6. In a well the combination with 'a valveseat having an undercut outer circumference, and a puppet-valve having a vertical stud arising therefrom, of a spider having a perforated boss engaged by said stud and having elastic legs that spread over and inclose said valve and are provided with enlarged lower ends that engage the undercut portion of the valve-seat whereby said spider is removably retained in proper position to confine and guide said valve.

7 In a well the combination with a valveseat and a puppet-valve having a vertical stud arising therefrom, of a spider engaged by said stud and having legs that spread over and inclose said valve and have the inner edges of their extremities provided with a convexed double bevel and interlock with said valve-seat.

S. In a well the combination with a valveseat and a puppet-valve having a vertical stud arising therefrom, of a spider having a perforated boss engaged by said stud and having legs that spread over and inclose said valve and have the inner edges of their extremities provided with a convexed double bevel and removably interlock with the valve-seat.

9. In a well the combination with a valveseat and a puppet-valve having a vertical stud arising therefrom, of a spider engaged by said stud and having elastic legs that spread over and inclose said valve and have the inner edges of their extremities provided with a convexed double bevel and interlock with said valve-seat.

10.- In a well the combination with avalveseat and a puppet-valve having a vertical stud arising therefrom, of a spider having a perforated boss engaged by said stud and having elastic legs that spread over and inclose said valve and have the inner edges of their extremities provided with a convexed double bevel and removably interlock with the valve-seat.

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

TIMOTHY 4 STEBBINS.
