PIPE-WELL COUPLING.
SPECIFICATION forming part of Letters Patent No. 378,234, dated February 21, 1888.
Application filed January i3, 1887. Serial No. 224,258. (No model.)
To @ZZ whom it may concern:
Beit known that I, MATTHEW T. CHAPMAN, residing at Aurora, in the county of Kane and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Pipe-Well Couplings, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a sectional elevation of the coupling and a well pipe or tube showing the strainer-tube and the piston-rod and valve in elevation; Fig. 2, a sectional elevation of the coupling; Fig. 3, a cross-section on line x xof Fig.V 1; Fig. 4, a sectional elevation of the valve base or plug; Fig. 5, a top or plan view of the valve base or plug; Figs. 6 and 7 ,elevations showing different forms of valves.
This invention relates to pipe-well couplings; and it consists in the novel features of construction and new combinations Vof parts hereinafter fully described,and then definitely pointed out in the claims.
In the drawings, A represents the wall or body of the coupling, having at its lower end an outward extension, a, which forms a lip around the exterior and having its end provided with a countersink, a', as shown in Fig. 2, to give the lower end, in conjunction with the lip, a cutting edge. The upper end,or end which receives the welltube,is cut out so as to leave an extension or collar, A', having an interior diameter corresponding to the exterior diameter of the tube, so that when the coupling is in place on the tube the collar A will be in contact with the tube and addl to the strength of the joint.
B is an opening formed in the end wall of the coupling for the passage of the strainertube.
C is an opening formed in the bodyAof the coupling to receive the head of the strainertube, such opening being of a greater diameter than the opening B,so as to leave a ledge,b,for the head of the strainer-tube to rest upon.
D is a tapering opening formed in the body A, connecting with the opening C.
Eis an interior screw-thread in the body A, adjoining the opening D, by means of which 5o the couplingcan be secured to the screwthreaded end of the tube or pipe.
F is a strainer-tube having an enlarged portion or head, c, and a point, d, with gauze f around its body between beads or rings e. The diameter of the tube F is such that it is able to pass through the hole B, and the diameter of the head c corresponds,or nearly so, to. that of the hole O,so that when the strainertube is in the coupling the head cl will rest against the iiange b.
G is a base or-plug for the valve, having a tapering exterior, as shown in Fig. 4, to correspond with the taper of the hole D,and having, as shown, a packing, G', inserted in its body, and at one end the plug G is provided with a screw-threaded nipple, g, and across its interior is a bar, g', to prevent a ball-valve, when used,i`rom dropping into the base or plug in case it becomes worn.
H is the valve cage or casing formed of an end head, h, and an end ring, h, connected by bars h, the end ring having a screw-thread to receive the screw-threaded nipple g of the base, and, as shown, the end head, h., has a screw-threaded nipple for the attachment of a rod, by means of which the valve as a whole can be withdrawn. A
I is a ball-valve located in the cage I-I, as shown in Fig. l. Instead of a ball-valve a cylindrical valve, I', as shown in Fig. 6, can be used, or a valve, such as shown in Fig. 7, having a spiral stem,can be used,and with the valve of Fig.,7 the cross-bar g will have to be omitted.
J is the pipe or tube having a screw-thread at its end for the attachment of the coupling A through the screw-thread E.
K is the valve for raising the water in the pipe or tube attached to apiston rod or stem,L.
rlhe strainer-tube F,with its head c thereon, is inserted in the coupling to have the head rest on the ledge b. The plug or base G,with the valve-cage and valve, is inserted in the coupling to have the base or plug Grin the hole D therefor, and the coupling A is then screwed onto the end of the pipe J, completing the de vice ready for use.
The coupling A,when the parts are together, furnishes the means for holding the strainertube, and, in connection with the base or plug Gr,forms a water-joint for the valve,so that the water can pass through the valve and enter the tube J, and by providing the extension A for the coupling A it will be seen that the juncture of the coupling with the pipe is extended sonie distance onto the exterior of the pipe above the screwthread,by which means, in case of side blow or strain,the coupling has a support on the pipe by which an increased strength is given to the joint, so that it will not be liable to break from side strain,and by using the aring end a at the bottom particles of earth remaining in the hole after the passage of the drill will be sheared ott, facilitating the insertion of the tubing.
The form of point F shown is one having a Wire-gauze to form a strainer; but any of the well-known forms of points can be used, such point being provided with a head, c, to rest upon the shoulder or ange b.
What I claiin as new, and desire to secure by Letters Patent, is
