IMPROVEMENT IN PUMPS FOR TUBULAR WELLS.

Specification forming part of Letters Patent No. l, datedJuly 27, 1875; application filed i June 10, 1875.

To all 4whomt may concern:

Be it known that I, JAMES T. WHIPPLE, of Oak Park, in the county of Cook and State of Illinois, have invented a new and useful `Improvement in Pumps for Tubular Wells;

and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawing forming part of this specification, in which- Figure l is a vertical central section of a portion of a tubular well embodying my said invention, showing the respective parts in the well in position for use. Fig. 2 is a sectional plan taken on the line w a: drawn across Fig. l; and Fig. 3 is a plan of the packing detached. Y

Similar lettersof reference indicate like parts in the several figures of the drawing.

The object of my present invention is to improve the device for which I obtained Letters Patent February 18,1868; and to that end it consists, first, in providing the valveseat with an annular depending dan ge, adapted to pass between the coupling and packing, whereby the latter is compressed between the flange and inner surface of the main tube; second, in providing the valve-seat with an annular groove, into which the upper end of the coupling loosely passes, in combination with a ile'xible packing arranged within' the groove between the end of the coupling and upper wall of the groove, and in the combination of the several parts, as will be more fully l understood by the'following description and claims.

In the accompanying drawing, A represents the main tube, which consists of wroughtmetal pipe, made in sections and connected together in the usual manner. B is the screen or filter proper, which is made of the proper diameter to pass loosely through the cavity of the main tube. This filter extends below the main tube into the water-course, and is made wedged-shaped at its lower end, as shown at a, Fig. l. C is an annular collar or coupling, which is permanently attached to the upper end of the lter, and is provided with a cavity, D, the lower end of which corresponds with the cavity inthe filter, lthrough which the water iiows upward into the main tube. The upper portion of this coupling is slightly less in diameter than the diameter of the cavity in the main tube, and is cut away in part, foi-ming a shoulder, d, as shown in Fig. l. The outer surface of the coupling, immediately above the shoulder, is screw-threaded, as shown at e, the threaded portion extending upward to a point near midway between the shoulder and end of the coupling. E is the outer packing, which is' secured around the threaded portion e of. the coupling immediately above shoulder d. This packing consists ofan annular gasket, as shown in Fig. 3, cut from sheet rubber or other. suitable elastic material. The diameter of the opening through this packing or gasket is less than the diameter of the threaded portion of the coupling around which it is secured, by which means, when adjusted to its place, the elasticity of the material causes its lower edge to iit firmly against the coupling, and its upper edge to flare outward slightly toward the inner surface of the main tube. F is the valve-seat on which the lower valve F' is seated. The lower portion of this valvcseat is made less in diameter than the upper portion, and is screw-threaded externally, corresponding with a like screw-thread on the inner surface ofthe coupling, as shown atf, by which means the valve-seat and coupling are secured together. The diameter of the enlarged portion of the valve -seat above its connection with the coupling is slightly less than the diameter of the cavity in the main tube, and is provided with a vertical annular groove, G, into which the upper end of the coupling loosely passes, the outer wall of the groove extending downward, forming a depending annular flange, H. This iiange isbeveled on its lower outer corner, and is adapted to pass between the outer surface of the coupling and the inner surface of the upper portion ofpacking E when the valveseat and coupling are screwed together, by which means the upper edge of the packing is forced outward and compressed between the outer surface of the flange and inner surface of the main tube, insuring an air and water tight joint between the wall of the tube and outer surface ofthe valve-seat below the valve. J is an annular ring of rubber or other flexible packing, adapted to closely t groove Gr between its upper wall and the upper end ot' the coupling C, insuring an air and water tight joint between the valve-seat land coupling when the saine are screwed together. The upper surface of the valve-seat is provided with a bail, K, made as a part of the saine, andextending upward slightly therefrom, as shown in Fig. 1, the object of which is to provide a means for .adjusting the seat within the main tube and to the coupling after the filter or screen has been properly placed in the Water-course.

My invention is arranged for operation in the following manner: Tube A is rst driven into the ground toa requisite depth. Screen B, with the packing-ring E arranged around coupling C, is then introduced into the cavity in the tube, and passed through the saine into the watercourse, allowing the coupling and packing' to project upward into the tube. Valve-seat F, with packing J arranged within groove G, is then passed through the tube and screwed in-to the coupling, flange H passing between the coupling and packin gE, conipressin gthe latter between the flange and the inner surface of the main tube, while at the saine time packing J is compressed between the upper end of the coupling and the upper wall ofthe groove, forming an air and water tight joint between lthe valve-seat and tube, and also between.

tion valve (not shown) is then-introduced into the inain tube, and connected to the pumphandle by the plunger-rod in the usual manner when the well is complete.

Having thus described my invention, I do not claim the tlter extending below the main tube, for such is shown in the patent to Duck and Whipple; nor do Iclaim broadly the combination ofthe filter with the valve-seat, for such is shown and claimed in the reissue of my original patent, dated February 18, 1868 5 but what I do claim is l 1. The valve-seat F provided with the depending flan ge H, adapted to pass between the coupling and packing, whereby the latter is coinpressed between the ange and inner surface of the tube, as specied.

2. The valve-seat F provided with the vertical groove G, adapted to receive the upper end of the coupling, in combination with'packing J as specified.

3. In combination with the valve-seat, coup ling, and in'ain tube, the packings .E and J, arranged for joint operation to secure'an air and water tight joint below the valve at the junction of the valve-seat with the coupling, as specified.
