PUMP.

SPECIFICATION forming part of Letters Patent No. 758,828, dated March 1, 1904. Application filed January 20, 1903. Serial No. 139,822. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN HAHN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Pumps, of which the following is a specification. A

This invention relates to pumps, and particularly to pumps applicable for deep wells, and has for its primary object the provision of a .pump which may be particularly adapted for pumping oil or water mixed with sand or other solids with ease and effectiveness and which will not clog or become stuck.

' A further object is to provide such a pump of most simple, cheap, and durable construction which shall be extremely positive and eiflcient in operation.

To these ends the invention consists in the constructions and in the general and specific combinations of parts hereinafter described, and set forth in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming part of this specification, in which- Figure I is a longitudinal sectionall view of a pump embodying my invention. Fig. II is an enlarged fragmental longitudinal sectional viewtliereof. Fig. III is a plan view on the line III III of Fig. II. Fig. IV is a plan View on the line IV-IV of Fig. II. Fig. V is a sectional view of the valve which I employ.

v As shown in the drawings. 2 represents the Working barrel of the pump; 3, the pump-piston; 4., the cage for the upper or piston-valve. This cage 4. preferably consists of the upward extensions or standards 5, which are provided on their innerfaces with guides 6. The cage 4. is suitably connected with the piston 3', asv

by a suitable threaded portion (not shown) adapted to engage a threaded portion (not shown) of the piston in the ordinary or any preferred manner.

The lower end of the piston 3 is provided with an engaging portion 7, adapted to engage the upper end of the lower valve-cage 4.', similar in construction to the upper valve-cage 4, having, as shown, similar standards 5 and and threaded portion, as shown.

guides 6. The lower end of this cage 4. is

connected with theJ barrel or pipe 8 by means ofthreads, Yas shown. A removable valveseat 9 is provided at the upper end of Athe' barrel or pipe 8. This barrel or pipe 8 is preferably provided with small fine holes 9 55V for the outlet of any gas that may accumulate in the pipe 8.

10 represents an extension of the working barrel, connected thereto by suitable threads sion 1() has a series of ribs 11 with open spaces or slots therebetween. The Vinner faces of these ribs are inwardly inclined, as shown, so that .they form'springs to retain the barrel or pipe 8 in place. `By lowering thepiston 3 and 65 engaging its screw-piston 7 with the upper end of the valve-cage 4 the pipe or barrel 8 may be raised.

12 represents the valves, the upper and lower valves and valve-cages being preferably of the 7o same construction and are so indicated in the drawings. The valves 12 are preferably recessed at 13 on their under sides, as shown best in Fig. V, and provided on the top with an upwardly-extending feather-Web 14., which may be of reduced thickness at 15` midway between its Wings 16, which terminate in upwardlyprojecting points 17. The wings 16 of the feather-web play in the guideways 6, which are preferably of a materially greater width than the edges-of the wings 16, the parts being thus constructed to avoid any liability of jamming or clogging with sand or other solid matters. The valves 12 preferably have cavities 18 on opposite sides of the feather-web. The under 8 5 I side of the valves may be beveled or rounded, as at 19, around the edge to t inv the valveseat. They are preferably semispherical, as shown.

In practical operation the downstrole of the piston in a liquid will cause the valve to be upborne by the liquid, the concavity on the under side of the valve serving to prevent the ready downward movement of the valve through the liquid. 'This allows the plunger 95 to pass down through the liquid, which flows freely throughthe valve-seat and around-the valve and passes up on eachside of the feather- This exten- 6 0 web 14 and acting thereon tends to hold the valve in true vertical position. The liquid is deflected outwardly by the valve bottom against the valve-seat and will keep the seat free from any accumulation of sediment, so that on the return stroke the valve may seat truly. Upon the upstroke of the vpiston the liquid is caught in the cavities or cups on the opposite sides of the feather-web, and the weight of the liquid therefore assists to quickly seat the valve,` thus making the action of the valve very quick. The pressure of the fluid upon the opposite sides of the feather-web and in the top cavities tends to hold the valve true, so that the beveled or rounded rim 19 will seat true in the valve-seat. On a return downstroke of the piston the valve is again upheld by the liquid, and in case there may be any solid material in the guides 6 the points 17 will pass the obstruction and force it out of the way between the guides without any danger of packing or jamming of the parts.

A convenient and effective form of construction is shown in which the edges of the featherweb terminate in chisel-points, the edges of which extend transverse the feather-web at the outside thereof. The lower ends of the guides 6 may also be beveled, as indicated at 20, in order to avoid clogging.

It is seen that I surely seat the valve at the upstroke of this piston, and in attaining this object I furnish the upper end of the valve with a tail or feather-web corresponding in function to that of the feather-web of an arrow, wherebythe liquid through which the valve passes serves to hold the valve true in guides in which the edges of the feather-web move.

The valves and ways herein shown and described originally formed part of the subjectmatter of my application filed January 30, 1902, Serial No. 90,530.
