STRAINER FOR sucrlon-mps's F PUMPS.

I l SPECIFICATION forming part of Letters Patent No. 408,487, dated August .6, 1889.

Application filed January 26,1889' Serial No. 297,723. (No model.)

To all whom it may concern:

' Be it known that I, OMAR 1T. JEWELL,a citizen of the United States of America, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new 1 it has been my object to provide a strainer that with, very narrow openings will afford a large inletof water, and in which the width of the openings callbe readily adjusted to be more or less, and which can be easily cleaned by expanding such openings either by hand or by a reverse stream of water; and with these objects in View my invention consistsof the novel devices and combinations of devices hereinafter described and specifically I claimed.

A- denotes the coupling, being interiorly screw-threaded for-connecting the same with the lower screw-threaded end of the suctionpipe of :a pump, and having a spirallygrooved extension (1, for coupling one end of spiral B, formed of wire, with its coils in close contact, and this extension (1 again hav ing connected to be rigid therewith a U- shaped yoke b, extending into the spiral B, to

screw 1) to be passed through it.

justing-screw D has a collar 11' shouldering provide a guide for such spiral. The lower end of spiral B is wound upon the spirally- "grooved rim of a cap 0, having an ey through its central hub for the stem of an ad 1];lI1l Stlnagainst the upper or inward face of cap 0, whileits screw-threaded end is tapped'through the bottom end of yoke'b. This screw D has also ahandle e, which may be ring-shaped,

Corresponding letters of reference desig for turning this screw by hand, and a setscrew f is tapped into the central hub of cap 0 for holding the screw from turning after having been adjusted.

By turning screw D in a left-hand direction the spiral B will be elongated to any desired extent for increasing the interstices between the ooils, and by turning the same in a right-hand direction the interstices between the coils will be decreased all uniformly, so a sufficient amount of water may be admitted therethrough, excluding all solid matter contained-in the water.

' 'The advantageof a strainer so constructed is that it provides a spirally-continuous opening for admitting water, that with being very narrow, will yet provide more entire opening than with perforations made of much larger width or diameter, and'that the width of this spirally-continuous opening can be readily adjusted to be more 0r less. I

Another great advantage is that after loosening the setscrew the spiral can be 810111 gated by hand by grasping cap 0 and pulling it downward, when all solid matterclogging between the coils from the suction of the water will drop ofi, and then by releasing the said cap'the coils will close again to a degree the screw D will permit, which also can be accomplished by reversing the current of water to pass from the pump through the suction-pipe, thereby forcing out all solid mattime the spiral may be also elongated by-the pressure of the water passing through it. The set-screw f may be omitted, or its point may enter a longitudinal groove cut into the stem of screw D for preventing such screw D from turning, and still permit the piece 0 to slide thereon, for the spiralB to be expanded either water.

What I'claim is-- A 1. Astrainer for the suction-pipe of apump or siphon, consisting of a wire spiral secured with one end to a coupling-nozzle provided with a guide-yoke that extends into the spiral, and with its other end to a cap having an eye for the collared shank of an adjustingscrew tapped into the guide-yoke for elonter gathered between the coils, during which- -by-hand or from a reversemurrent of the gating or contracting sneh spiral, Substantially as and for the purpose set forth.

2. A strainer for the suction-pipe of a pump or siphon, consisting of a wire spiral secured with one end to a coupling-nozzle that extends into the spinal, and with its .other end to a cap having an eye for the Collared shank of an adjusting-screw tapped into the screwnozzle for elongating and eontraeting thespiral, said screw being provided at its lower 10 projecting end with a handle for turning, said screw, all substantially as set forth.

In testimony whereof I affix inysignatuie in presence of two witnesses.
