ALBERT P. ODELL, OF SHAMBURG, PENNSYLVANIA.

lMPROVEM ENT lN GIL-PUMPS.

Specification forming part of Letters Patent No. 134,993, datedDecembcr 17, 1872.

To all whom it may concern:

Be it known that I, ALBERT P. ODELL, of Shamburg, in the county of Venango and State of Pennsylvania, have invented certain Improvements in Oil-Pumps, of l which the following is a specification:

M y invention relates to pumps for oil-wells; and consists in acertain improved combination, construction, and arrangement of parts, as hereinafter described.

Figure l is a longitudinal view of .the exterior. Fig. 2-is a longitudinal section through the center.

Similar letters of reference indicate corre- I spending parts in the several figures.

A is the working-barrel; B, the hollow pist0n stem or plunger which carries the working-valve t, the top of the valve-cage being attached to the sucker-rods by screwing onto it. The lower ball-valve c' and cage is attached to the lower end of the workingbarrel A. To the upper end of the lworking-barrel A I at;

ltach the stuffing-box D, with its cap C, condesired to withdraw the pump from the socket and tubing the hollow pistonrod or plunger B is raised till the colla-r g, attached to the lower end thereof, strikes the lower shoulder of the packing-box D and loosens the pump from the socket. The pump with all its parts is then withdrawn without drawing out the tubing. y

In operating my improved pump, the workingbarrel A, with the standing-valve 'u' attached to the lower end, is lowered to the bottom of the well. The upper end of the hollow plunger B being attached to the sucker-rods, the plunger is worked up and down and the oil forced up through the plunger into the tubing above, and thus flows up and out at the top.

Having thus described my invention, I claim as new and desire to secure by Letters Iatent- 1. The self-packer, consisting of the stuft'- ing-box D, packing p, gland i", and spiral spring s, constructed and arranged substan tially as set forth.

2. The socket S, constructed substantially as and for the purposes set forth.

3. The arrangement and combination of the plunger B, stuffing-box D, working-barrel A, socket S, and tubing T, substantially as and for the purposes set forth.

ALBERT P. ODELL.
