B. H. DAVIS DEVICE FOR REMOVING LINERS AND VALVE SEATS OE PUMPS Filed March 30. 1922 Patented May 6, 1924.
l 1 UN TED S m-ms BERNARD H. Davis, on rurmnnromohnironnra DEVICE FOR R moVING IjrNEns Am) VALVE SEATS or PUMPS.
Application .filed March '30," 1922. Serial ml 548,257;
To all it may concern:
Be it knownthat I, BERNARD H.-D'AvIs, a citizen of the United States, residing at Fullerton, in the county of- Orangeand State of 5 California, have invented" new and useful Improvements in Devices for Removing Liners and Valve Seats of Pumps, of which the following is a Specification;
My invention relates to device forre moving the liners and valve seats of pumps,
and particularlythosepumps that are utilized for pumping mud, sand,or the like from oil wells, the principal objects of my invention being to provide a relatively simple and practical device that may be readily inserted in a pump or valve cylinder and which when properly manipulated will readily unseat and draw the liner or valve seat from the pump cylinder.
It will be understood that pumps that are utilized for pumping mud, sand and the like from well holes are provided with removable liners and with removable seats for the valves, and these parts very frequently become rusted in the pump cylinder, with the result that much time and labor are involved in removing these parts when the same have become worn so as to render them unfit for service. I propose to provide a relatively simple device that may be easily and quickly engaged on the inner end of a liner or a valve seat and which device will very quickly disengage the liner or valve seat and withdraw the same from its working position within the pump or valve cylinder.
With the foregoing and other objects in view, my invention consists in the features of construction and combination and arrangement of parts hereinafter more fully described and claimed, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a pump liner and valve seat removing device of my improved construction;
Figure 2 is a vertical section taken lengthwise through the center of a pump cylinder showing my improved device in position to remove the liner of said cylinder;
Figure 3 is a vertical section of a portion of a valve housing showing my improved device in position to remove the annular member that forms the valve seat.
Referring by numerals to the accompanying drawings, which illustrate a practical embodiment of my invention, 10--10 designate a pair of: semi-cylindrical blocks of identical size and'form, the inner faces of avhich blocks are slightly inclined in opposite directions so as to form a --substantially wedge-"shaped opening between the blocks with the'narrow edgeorapex of said opening at the upper ends of the blocks. Each blockgis provided on its lower circumferential edge with" an outwardly projecting flange l-l and the blocks are hinged to each other at their upper inner edges in any suit.- able manner, preferably by means of hinges 12, the wings of which are fixed to the tops of the blocks. Formed in the inner inclined faces of the blocks 10 are centrally arranged longitudinally disposed grooves or channels 13, which combine to form an axially disposed opening through the cylindrical memer that is formed by the two blocks and arranged to slide freely through this opening is a rod 14, one end of which is threaded as designated by 15, in order to receive a nut 16. Formed integral with or fixed to the opposite end of the rod 14 is a wedge block 17, and formed inte al with the lower end thereof and projectlng outwardly from its wider faces are substantially semi-circular flanges 18.
In removing a pump liner with my improved device, the head, piston and piston rod of the pump are removed and the wedge block 17 and cylindrical member composed of the hinge blocks 10 are inserted into the pump chamber until the inner ends of the blocks 10 or the ends provided with the flanges 11 occupy a position beyond the inner end of the liner. The rod 1 1 is now drawn outwardly a sufficient distance to spread the flanged ends of the blocks 10 apart until the flanges 11 engage against the inner end of the llner L, as illustrated in Figure 2. A crows foot or cross bar is now placed over the outer end of rod 14, and transversely arranged across the pump cylinder chamber, and nut 16 is now secured on to the threaded end of the rod. As nut 16 bears against the crows foot or cross bar, rod 14 carrying the wedge block 17 will be drawn outwardly with the result that the wedge block will, through the blocks 10 and flanges 11, exert suflicient pressure against the inner end of the liner L to disengage and unseat the same, and a continued screwing of the nut 16 on to the threaded end of the rod will draw the liner outwardly from the pump chamber until its outer end can be engaged by suitable tools or clamps.
In Figure '3 I have shown the device in engagement with an annular ring that serves as a valve seat, and the operation of removing this ring with the device is practically the same as the liner removing operation above described.
A device of my improved construction is comparatively simple, may be easily and cheaply produced, and is instrumental in effecting a material saving of time and labor in the removal of pump liners, valve seats and the like.
It will be understood that minor changes in the size, form and construction of the various parts of my improved device. for re moving the liners and valve seats of pumps may be made and substituted for the parts herein described and illustrated without departing from the spirit of my invention, the
scope of which is set forth in the appended claims.
I claim as my invention:
1. In a pump liner and valve seat removing device, a pair of blocks hinged directly to one another, an externally threaded rod arranged for axial movement between said blocks, and a wedge carried by said rod and adapted to pass between said blocks.
2. A pump liner and valve seat removing device comprising a pair of substantially semi-cylindrical blocks hinged directly to one another provided with shoulders that are adapted to engage the .part to be removed,
an externally threaded rod arranged tomove freely between said blocks, and a wedge block carried by said rod.
In testimony whereof I have signed my name to this specification.
BERNARD H. DAVIS.
