AUTOMATIC CHECK FOR 4OIL-WELLS.
SPECIFICATION forming part of Letters Patent No. 429,317, dated J' une 3, 1890.
Application filed July 24, 1889. Serial No. 318,509. (No model.)
To all whom it may concern:
Be it known that I, JOSEPH ONE'IL, a citizen of the United States, residing at Taylorstown, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Checks for Oil-Vells; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to oil-well checks; and it consists in an improved construction of automatic oil-well checks, as hereinafter set forth and claimed.
In the accompanying drawings, Figure l is a vertical section of my improved check in position in the tubing of a well. Fig. 2 represents a side View of the check. Fig. 3 rep-V resents a vertical section of a well-tube provided with my improved check and other devices.
A designates the tubular body of the check, the said body extending into the working-barrel B and resting at a thereon. A ring b is screwed to the lower end of the body A and secures a cup-leather, which forlns a close joint with the barrel. j
O indicates a housing or cage, in which is placed the valve D, the said cage being screwed to the body A and having apertures c, which are opened and closed by the movement of said valve. The valveD has atubular stein, which extendsupward, and to the valve-stem is secured a stuiling-box E, which is provided with packing d, as shown. A follower g is placed in the stufiing-box over the packing, and a perforated cap F is screwed to the top. The apertures e in the cap admit the iiuid, which presses the follower downward, and thus compresses the packing. The sucker-rod extends down through the check, passing through the stufng-box and checkvalve, the check being placed on the rod and passed down into the tubing Gr.
vstroke of the rod.
m indicates the working-valve in the piston-head, carried by the rod h, and k indicates the foot-Valve in the working-barrel. By this construction the check is automatic in operation. At each upward stroke of the rod h, which passes down through the check,
. the valve D and stuffing-box are raised by the rising fluid, which passes out through the apertures c, and is prevented from returning by the closing of the valve on the downward The working-valve in the piston is thus to a certain extent relieved on the downward stroke of pressure from the oil which has passed up through the valve-case.
The cup-leather, secured by the ring b, serves to keep the body Ain place and forms a packing between the working-barrel and the tubularbody A, which prevents the passage of oil outside of said body. The packing d in the stuffing-box is compressed and kept in good condition by the'pfluid entering the stuffing-box through the apertures e in the cap F and pressing down the follower g,whicl1 is loose on the rod h.
I claiml. In an oil-well check, the combination, with a tubular body, of a perforated housing or cage secured thereto, a tubular valve placed in said cage, a stuffing-box connected withr said valve and provided with a perforated cap, a follower g, and a sucker-rod, substantially as and for the purposes described.
2. The combination,with the tubular body provided with a ring b and packing, of the working-barrel B, a perforated housing secured to said body, andavalve placed loosely in said housing, substantially as and for the purposes described.
In testimony whereof l have aixed my signature in presence of two witnesses.
