|. L. AULT VALVE SEAT REMOVING TOOL FOR PUMPS J Filed Jan. 29; 1924 A TTORNEYS.
Patented Dec. 2, 1924.
UNITED STATES PATENT OFFICE.
VALVE-SEAT-REMOVIN'G TOOL FOR, PUMPS.
Application filed January 29, 1924'. Serial No. 689,312.
To all whom it may concern.
Be it known that I, Isl-mo L. AUL'r, a
citizen of the United States, residing at Comanche, in the county of Stephens and State of Oklahoma, have invented certain new and useful Improvements in Valve-Seat- Removing Tools for Pumps, of which the following is a specification.
This invention relates to improvements in tools and refers moreparticularly to a valve seat gripping and removing tool.
The principal object of the invention is to provide a tool for use in removingworn and faulty valve seats in oil well and mud. pumps and varied classes of pumps or the like.
The invention is also designed with a view to its durability, ease of operation and economical manufacture, and in this connection is also adapted to save considerable time and labor.
The new and improved valve seat lifting tool will be clearly understood by reference to the following description, taken in connection with the accompanying drawings forming part hereof and in which:
Figure 1 is a side elevational view of the invention, one side of the housing being removed to reveal the interior.
Figure 2 is a detail view of the lower end or gripping portion of the tool.
Figure 3 is a top or plan view taken on line 3-3 on Figure 1.
Figure 4 is a detail view of the operatin handle of the tool; and,
Figure 5 is a vertical sectional view of i a pump and illustrating the invention in operative position thereon.
Continuing the description of the device and referring to its various parts more in detail; the numeral 1 denotes a casing enclosing a series of pinion gears 2-2 and rollers 3-3 supported upon suitable pins as shown.
The casing 1 converges upward and forms a reduced end with an inner abutment 4. An opening in the abutment permits of the outward extension of a squared end sleeve 5 interiorly screw threaded and provided with a shoulder 6 which retains the sleeve in position against abutment 4.
Within the casing 1 is a toothed. bar 7, the upper end 8 of which is reduced in diameter and screw threaded for reception into the sleeve 5, clearly shown in Figure 4. This bar 7 is in mesh on each side with the pinion gears 2-2, previously referred to and i these gears in turn co-act with a pair of puller arms 10-10 in connection with the rollers 3-3, the latter for the purpose of retaining the toothed arms in alinement or mesh with the gears. The rollers 3--3 ride between the backs of the arms and a tracking 11 as the arms are operated.
Spaced between the lower ends of the puller arms 10-10 is a valve seat gripping member consisting of two halved part 12-12 hinged together by a rod 13 which likewise holds the arms 10-10 to the parts 12-12. Between the halved parts 12-12 of the gripping member is a spring 14: for the purpose of providing outward tension on the parts 12-12 as they are pushed into the valve seat. These parts, as will be seen are rounded and are provided with shoulders 15-15 so that when pressure is applied, they ride past the valve seat A in pump B and are thus locked beneath its lower end.
From the above, it will be seen that the tool may be inserted into the pump cylinder, and the sleeve 5 rotated which will force the valve seat gripping members into and beneath the valve seat until they spring out past the shoulders 15-15. The rotation of the sleeve is now reversed, causing the bar 7 and puller arms 10-10 to lift the seat.
It should be understood that modifications and changes may be made in the construction of the device in keeping with and within the scope and meaning of the following claims.
I claim- 1. In a device of the nature set forth; a pair of toothed arms, the upper ends movably arranged in a casing; valve seat gripping members carried on the lower ends of the arms; a toothed bar and pinion gears arranged to co-operate with the toothed arms; and a sleeve upon the toothed bar for moving the bar to operate the arms and valve seat gripping members against a valve seat to remove the seat.
2. A valve seat removing tool for pumps or the like, comprising a casing, a pair of spaced puller arms with teeth on their inner surfaces and movable within and depending downward from the casing and carrying valve seat gripping members; a bar having toothed sides and meshing with pinion gears disposed between the sides of said bar and said arms; guide rollers between the arms and the casing; a sleeve upon the upper end of the bar arranged so that when moved thereupon it will cause the valve seat gripping members to engage and remove the valve seat.
3. A valve seat removing device for pumps or the like comprising a casing, depending therefrom; a bar With a sleeve coacting with pinion gears and said arms to move the arms; valve seat gripping mem- 10 bers carried on the lower ends of the arms;
said members being rounded and provided with projecting shoulders and under spring tension; said shoulders adapted to be projected beneath the valve seat when under pressure to engage the valve seat, the movement of the sleeve acting to loosen and re move the valve seat.
In testimony whereof I have signed my name to this specification.
