Slpeciiication forming part of Letters Patent No.1`7`0,124, dated Novfimber I6, 1875 application led August 16,1875.

To all whom it mag/concern Be it known tha-tI, PRATT A. SPICER, of

the city of Marshall, State of Michigan, have invented certain new'and useful Improvements in Pumps, of whichthe following is a full and accurate description, reference being had to the accompanying drawing andthe letters of reference thereon.

Like letters refer to like parts in the different figures.

and coupled to the section A by means of a plain straight coupling, B. Over each of `these rows of holes z is laid a strip of sheet metal, L. These strips of metal are laid .so close to the surface of O as to leave Aonly a very narrow passage on each side of the strip to the holes z--indeed, are hammered` or pressed so closely'to the surface of G as to serve the 'purpose of a veryiine strainer, and do away with the necessity of using wire-gauze for covering the openings. Through these openings the water at the bottom of the well is admitted to the pump. Inside the pump A is a cylindrical lining, F, of suitable material fora pump-cylinder. This lining is secured by turning a ange, t', upon its lower end, which lies be- Y tween the ends of the two adjoining sections within the coupling B, as shown in section in Fig. 2. The filter E is accurately fitted to the inside of the pump-cylinder F, so that when` pushed into its place, as shown in Fig. 2, it

will be held securely by its friction against the" inside of the pump cylinder; or, when the pump-cylinder is placed higher up in one -of the upper sections of the pump, a short lining, fitted in the saine manner as the pump-cylinder, may take its place, to which the filter may be fitted; or the pump-cylinder may be entirely ldispensed with and the filter fitted directly to` the main tubing of the pump. The filler is `pierced with holes all around, as shown, and

may .be filledto a with any suitable filtering materials.

threaded at both ends, leaving a short distance plain, on which the valve d rises and falls easily. The valve-seat n n has passages o c for the How of the water. Its central portion is screw-threaded internally tolreceive the stem r. The follower o o slips onto the stem r, and is secured in place by the nuts s s. The valve-seat a a has its lower-edge beveled externally to correspond with the beveled edge of the follower 0 o, beveled internally. Between these bevelededges a ring, l, of leather, or other suitable material for packing, is placed and held securely by forcing up the follower o o by means of the nuts s s. The stem r is united to the pump-roil by means of the small screw-coupling P. This coupling serves the double purpose of uniting the plunger or valve K with the pump-rod s, and at the same time forming an adjustable stop for the valve d. The throw of the valve may be regulated by loosening the nuts s s and screwing the valveseat n n up or down on its stem. Gr is a solid metallic point screwed into the bottom of the casing C for piercing the earth when used for a driven well, or for the pump to rest upon in an ordinary dug well. p

I am aware that metallic strips have before been used to partially cover the holes in points or casin gs of driven pumps; but these have been used only as mere protections to the gauze covering of the holes, and have not been arranged in any such manner, or withany design to serve as strainers, while, with my arrangement, they form a strainer elfectually ex 'cluding even the finest sandpwhich a Wirei OFFICE.

y The space above a. is left clear for .water-room. The top of the ilteriis closed some, and often expensive, process of drawing up the entire pump. I therefore do not, broadly, claim a filter.

I am aware that pump-plungers or buckets having a leather ring clamped between the two` partsv as a packing have been long in use; but the faces between which the packing materials have heretofore been placed have been plane at surfaces with sharp square edges, necessitating the bending of the leather at right angles, and causing it to crimp badly, and at the same time liable to cut the packing. Mine, being beveled, brings the leather into shape before being introduced into the .pump, with no liability to cutting on sharp i Heretofore the stop for the valve d has been l made by welding a collar or lug upon the stein r. I place the coupling I in a new position, so that it takes the place of a valvestop, costing nothing, from the fact that a coupling is in all cases necessary. In this way I dispense with the expensive collar, using the coupling instead. Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is, viz:

1. The combination, with the casing C, having verticalV rows of holes z, of the metallic strips L, laid close to the casing over the holes therein, and leaving a narrow passage on both sides of each strip for the passage ofthe water to the holes, substan tially as herein shown and described.

2. lThe combination of the valve d of a pumpplunger with the adjustable screw-coupling P, to form an adjustable stop for the valve, sub stantially as shown and described.
