IMPROVEMENT IN VACUUM-PACKERS FOR OIL-WELLS.
Specification forming part of Letters Patent N 0. 204,512, dated June 4, 1878; application filed March 15, 1878.
To all whom it may concern:
Be it known that I, JAMES C. THOMSON, of Barnharts Mills, in the county of Butler and State of Pennsylvania, have invented a new and Improved Vacuum-Packer for Oil-Wells, of which the following is a specification:
Figure l is a plan View. Fig. 2 is a vertical section.
Similar letters of reference indicate corresponding parts.
The object of my invention is to provide an easily-operated and reliable packing device for shutting off communication between the upper strata of rock and the oil-bearing rock; and it consists of three apertured metallic disks placed on the well-tubing, and arranged to receive the vacuum tube, which, by its weight, compresses a rubber packing-disk vertically, so as to expand it laterally to fill the bore of the well.
Referring to the drawing, A represents the well. B is the well-tube, which is suspended from the casing-head in the usual way. Upon the tube are placed three apertured metallic disks, a b c, which are smaller in diameter than the well.
The lower disk a is placed below the pipecoupling 01. The middle disk I) is placed just above the coupling, and between the upper disk 0 and the middle disk I) there is a thick rubber packing-disk, c. This disk and the three metallic disks a b o are apertured to receive the vacuum-tube G, which is made in two parts, the lower part passing upward through the lower disk at, middle disk I), and rubber packing-disk 0 into the upper disk 0.
The upper surface of the upper disk 0 is concaved or countersunk around the vacuumtube aperture, to guide the upper section of the vacuum-tube to its seat in the disk. The lower end of the upper section of the vacuum-tube O is made conical, and is ground into the aperture in the upper disk 0.
Upon the lower end of the lower section of the tube 0 there is a collar, f, which prevents the tube from being drawn upward through the lower disk at, and, being screwed into the upper disk, it prevents the packing device from being drawn up with the vacuum-tube, and also insures the lifting of the whole of the packing device when the well-tube is removed from the well. The weight of the vacuumtube is sufficient to compress the rubber packing-disk 0, so as to expand it laterally against the sides of the well.
When the well-tube is to be taken up, the vacuum-pipe is first taken from the well. This releases the packing-disk e,.and the packing device may be drawn up together with the tube.
The vacuum-tube C may be employed to convey benzine to the bottom of the well.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of the apertured disks a b c, the elastic packing-disk e, and the vacuum-tube O, substantially as herein shown and described.
2. The combination, with tubes B C, of the disk a, placed above collar fand below the coupling d, as and for the purpose set forth.
JAMES C. THOMSON.
