y UNITED STATES PATENT OFFICE.
JOHN J. Gr. COLLINS, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN DEEP-WELL PUMPS.
Specification forming part of Letters Patent No. 5 [,148, dated November 28, 1865.
To all whom it may concern:
Be it known that I, JOHN J. G. GoLLINs,of the city of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in a Combined Oil and Gas Pump; and I do hereby declare the following to be a full, clear, and exact description ot" the construction and operation of the same, reference heilig had to the accompanying drawings, making a part of this specification, in Which- Figure 1 represents an external View of the combined pump. Fig. 2 represents a vertical section through the same, in the line of its length and Figs. 3 and 4 represent transverse sections through the pump.
Similar letters ot' reference, where they occur in the separate tigures, denote like parts oi' the pump in all the drawings.
My invention consists in so combining, in a pump, inlet, through and exit passages for oil and gas as that the operation ot' pumping shall raise and escape these two substances at dit'- rcrent points, and without allowing them to .commin gle at any part of their passage through the pump.
To enable others skilled in the art to mak and use my invention, I will proceed to describe the same with reference to the drawings.
a a represent a pump tube or pipe in which the pump bucket or plunger h works at its lower end or portion, the eXtreme lower end ot' the pump being furnished with a foot valve, z'.
The pump-tube is enlarged, as at b, and within this enlargement is placed a working barrel or cylinder, c c, so as to leave a space between the enlargement and the working-barrel ior the oil to pass through as it is raised by the action ofthe pump.
Within the working-cylinder c are two pistons, d d, made to fit and work snugly, butJ tight enough to prevent any leakage from above or below the pistons into the space between them.
Between the two pistons l d, and connecting them together there is a perforated tnbe,e, and openings f, from the outside ofthe pump-pipe, lead into and communicate with the interior ot' the working-cylinder c, and pass through the annular space between b c without communicating with said annular space. The pump-bucket h is connected to the lower piston, d, by means of the rod Z, so tnat they all work together by the simple working ot' the pump-rod.
o 0 represent a cylinder in which works a piston or plunger, P, at its lower end, while at its upper end is placed a discharge-valve, q.
'in is across-head for working the pump. It is attached or connected with the holow pumprod lr, through which the gas is pumped up, while said rod also carries or operates the other valve-pistons or plungers of the pump. rPhe cross-head moves on and is guided by the guide-rods u, and these guide-rods also support the upper pump-cylinder, o o.
It is an escape-valve, where the gas may escape into the air or from whence it may be taken to a furnace and burned.
rlhis embraces the general construction ot the pump. lts operation is as follows: The pump-rod being Set in motion,the oil is drawn through the foot-valve t by the bucket h, and thence it passes up between the workin g-cyl nder c and the enlargement b of the pump-tube, as shown atj gj; thence up between the hollow pump-rod 7c and the pump-tube a to the opening at S, whence it passes out to any receiver. While the oil is being thus received the gas is drawn in through the openings or tubes f into the space between the pistons dd, occupied by the perforated tube c, and through the perforations of said tube it is drawn into the hollow pump-rod r,and thence up through the bucket R, chamber o, valve q, and escapepassage Rfwhere it may be wasted or consumed, as above stated.
The gas may be taken into the pump at any point or points above the deposit ot' the oil, where it will always rise, owing to its verylight property.
Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-
Iu combination with a hollow pump-rod for operating valves or plungers for raising oil, as herein represented, the openings from the exterior of the pump-tube to said hollow pumprod, and through it to the exterior of the pump, for the purpose of, also, by the same operation, pumping out the gas from the well, substantially as described.
JOHN J. G. COLLINS.
