VALVE ATTACHMENT FOR OIL-WELLS.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed January 31, 1908. Serial No. 413,697.

To all whom it may concern:

Be it known that 1, JOHN MILLER REECE, a citizen of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Valve Attachments for Oil-\Vells, of which the following is a specification.

This invention consists of novel means for use in connection with water, oil, gas, or like wells for controlling the flow therefrom. In its particular adaptation the invention embodies an attachment to be applied preferably to the upper end of the well casing, and suitably anchored in such position, peculiar valve mechanism being provided to regulate or cut off the flow of oil, gas, or the like, from the well.

For a full understanding of the invention and the advantages thereof, reference is to be had to the following detail description, and to the accompanying drawings, in which:

Figure 1 is a top plan view of a device embodying the invention; Fig. 2 is a vertical longitudinal sectional view taken about on the line 22 of Fig. 1; Fig. 3 is an end elevation; and Fig. i is a detail perspective view of the valve and parts connected therewith.

Similar reference characters refer to similar parts in the drawings and description.

Specifically describing the construction and operation of the invention, and referring to the drawing, it is contemplated to provide an attachment to be secured to the well casing and consisting essentially of the spaced sides 1 provided upon the inner faces thereof with longitudinal grooves or guides 2. The sides 1 are connected together by means of bolts 3, the latter being of a suitable length to permit a certain amount of movement of the sides toward and from each other. Adjacent to one end of the device is arranged a cross piece t'the opposite end portions of which are mounted to move freely in openings 5 formed in corresponding adjacent ends of the side members 1. In other words, the cross piece 1- is mounted loosely on the members 1 by means of the openings 5, hence not interfering with any adjustment of the members 1 varying the relative positions of the latter.

Passing through the cross piece t is an adjusting screw 6 the inner end of which has a swivel connection at 7 with an end portion of a valve 8 mounted for slidable movement in the guide grooves or channels 2 of the side members 1. The valve 8 has its longitudinal edge portions beveled near the upper side thereof, as shown at 9, and correspondingly, the uppermost portions of the guide grooves 2 are beveled as shown at 2 for a purpose to be hereinafter described.

The valve 8 is supported upon a plate 10 the edges of which project into the guides 2 of the side member 1, said plate 10 being arranged above a two part clamp 11, and preferably secured thereto. The upper face or side of the plate 10 and the under side of the valve 8 are in contact and these contacting surfaces will be made perfectly true and smooth so that a tight joint will be provided when these parts are forced hard together by movement of the side members 1 toward each other, which. may be eifected by tightening the connections 3 between said members. The clamp 11 which is composed of two parts, the latter secured together by suitable nuts and bolts, is adapted to receive between its parts the upper end of a well casing 12. Preferably the clamp parts aforesaid have a threaded connection 13 with the well casing 12, the latter being threaded for this purpose, such connection being substantial and desirable in order to secure the attaching device in place. If found necessary, additional securing means may be employed to attach the clamp and well casing together, and the former will preferably be anchored by some substantial anchoring means to eliminate likelihood of accidental displacement thereof by the force of the confined. fluid in the well. 7 The side members 1 are thickened transversely at the middle portions of the same to increase the strength thereof at the points where the guide grooves are located.

The valve 8 is operable by turning the screw 6, and for this purpose a crank, wrench, wheel, or similar device may be applied to the squared outer extremity of the screw. lVhen the valve is adjusted so as to extend over the upper end of the casing 12, as shown in Fig. 2, the latter is closed and the closure made practically air tight by adjustment of the nuts of the bolts 3 so as to force the side members 1 of the attachment toward each other. This action causes the contacting beveled portions 9 and 2, of the valve and side members respectively, to so cooperate with one another to force the valve down tightly upon the supporting plate 10. Hence, though the valve 8 is freely slidable longitudinally between the side members 1, said members 1 are operable in an advanta geous manner described above to effect downward movement of the valve and establish the tight connection which eliminates likelihood of escape of the fluid contents of the well, in an evident way.

The valve 8 however, not only performs the function of a cut off valve, but is otherwise advantageously employed in an auxiliary capacity. Said valve 8 is provided with an outlet opening in which is tapped an outlet pipe 14, to which an elbow or any length of pipe may be attached and all connections put in preparatory for the regular flow of oil or gas, while the well is closed, or flow out off. Ordinarily much time is lost in making the distributing connections while the oil or is flowing from the well, not to say anything of the loss of the oil or gas which escapes in this operation. In the present in vention the pipe line connections may all be made with the pipe 14 and opening in the valve 8 so that it is only necessary to operate the screw 6 and move the valve into a position in which communication is established between the casing 12 and the pipe 14L, whereupon the fiow of gas or oil will commence without loss of time or escape of the contents of the well in a wasteful manner. The supporting plate 10 is of course provided with an opening to register with the opening in the valve 8.

The novel and advantageous features of the present invention will be recognized from the foregoing, and it is to be understood that the construction of the invention may be modified in accordance with the broad spirit thereof, and the scope of the appended claims.

Having thus described the invention, what is claimed as new, is:

1. In valve controlling means for oil wells, an attachment embodying spaced sides, a valve, means for actuating the valve to ef fect opening and closing movement thereof, and means for varying the relative positions of the sides and thereby effecting movement of the valve at an angle to its opening and closing movement.

2. In valve controlling means for oil wells,

an attachment embodying spaced side members provided with guides, a valve arranged between the side members, means for effecting longitudinal movement of the valve in the guides of the side members, a supporting member arranged in contact with a side of the valve and having an opening therein, and means for drawing the side members together, whereby the contacting surfaces of these members and the valve cause movement of the latter at an angle to its longitudinal movement, increasing the frictional contact between the valve and the supporting memher in engagement with a side thereof.

3. In valve controlling means for oil wells, a support embodying spaced side members, connections between said side members, 'a longitudinally sliding valve movable between the side members, the side members and valve having contacting surfaces, and means for adjusting the connections between the side members, the contacting surfaces of the valve and side members being beveled so as to cause movement of the valveat an angle to its sliding movement on adjustment of the connections between the side members.

4. In valve controlling means for oil wells, an attachment embodying spaced side members, adjustable connections between the side members, a valve longitudinally slidable with its longitudinal edges in engagement with the side members, a supporting plate mounted on the side members and having its upper surface in contact with the under side of the valve, clamp means connected with the side members for securing the same to a Well casing, the valve and the supporting plate being provided with openings adapted to register, a distributing pipe connected with the valve at its opening, and means for actuating the valve, the engaging portions of the side members and valve being beveled whereby when the connections between the side members are adjusted the valve will be forced downwardly into closer contact with the supporting plate.

In testimony whereof I aliix my signature in presence of two witnesses.
