HYDRAULIC PUMP'OR RAM,

SPECIFICATION forming part of Letters Patent No. 581,610, dated April 27, 1897'. Application filed August 19, 1896. Serial No. 603,232. (No model.)

To LZZ whom t may con/cern:

Be it known that I, PHILLIP O. PALMER, a citizen of the United States,residing at Aspen, in the county of Pitkin and State of Colorado, have invented certain new and useful Improvements in Hydraulic Pumps or Rams; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the art of water distribution, and has particular reference to engines or pumps for use in this connection, consisting, more definitelystated, in a hydraulic pump or ram, having among its objects the production of a more efficient device for automatically throwing water and other liquids; a simple arrangement of the drive-pipe, airchamber, check and Waste valves best suited to effect their harmonious coaction with the least possible friction or liability of derangement; a system of air equalizers or feeders communicating with the supply-ports immediately below their check-valves; means for automatically injecting a fresh-air supply into the air-chamber with each stroke of the pump, and a noiseless spring-pressed wastevalve suspended in a perpendicular chamber at extreme end of the structure actuated on horizontal lines.

The invention will be hereinafter fully described, and particularly pointed out. in the claims following.

In the accompanying drawings, forming part of this specification, and in the several views thereof, upon which like letters of reference indicate the same parts wherever employed, Figure lis an end elevation of my invention, showing its perpendicular valvechamber, a portion of the waste-valve therein, a hand-wheel for regulating the latter, and the air-chamber with delivery-pipes. Fig. 2 shows a vertical central longitudinal section through the waste-valve and base or body of pump,with a central transverse section of its air-chamber. Fig. is also avertical central section on the line 3 3 of Fig. 2, being taken transversely through the base or body and longitudinally through the air-chamber aforesaid. Fig. 4L represents a fragmentary detail View of pump-base on the line 4 4, Fig. 2,

partly broken away, exposing air equalizers or feeders. Fig. 5 is a plan View of the checkvalves employed; Fig. G, a detached perspective view of waste-valve, its stem, and flexible disk. Fig. 7 represen ts in perspective an adjustable elastic buffer for the waste-valve, and Fig. S is a stuffing-box employed shown in a plan view.

Reference being had to the drawings and letters thereon,Aindicates the main supplypipe, flanged at its inlet, as at B, and provided with projecting studs, as d, for the attachment of a corres pondingly-flanged drive-pipe. (Not shown.)

C represents the body of a waste-valve chamber east integral with the discharge end of pipe A, being of increased area and, as herein shown, of substantially square outlines, while from the upper surface of same pipe A projects a central valve-body D, also by preference cast integral with said pipe, serving to support a horizontal surrounding base E and perforated by parallel ports F F in communication with the interiorof pipe A. In addition to vertical valve-ports F F the end walls of body D are also perforated by small openings, into which are driven or screwed the hollow air-feeders G G, each opening into one of the ports aforesaid, consequently being in different horizontal planes, and each tapered or reduced at the upper end II, each projecting from base E at the same angle of inclination, but in opposite directions, and each arranged to automatically deliver air into the ports .F F near their upper or discharge ends at every stroke of the pump, as will later appear.

Ports F F are rectangular in form, are separated by an intervening wall or partition l), are surrounded upon their upper surfaces by suitable valve-seats c c, and are guarded by check-valves I I, the body portions of the latter being faced by an inlaid strip of hard rubber CZ or similar facings for contacting with the valve-seats c c, and both valves being bolted t0 supporting-springs e c, secured by set-screws f j" to the central partition h, as illustrated by Figs. 2 and 5.

Base E near its edges is configured by a continuous depression g for containing an airtight packing material, such as Babbitt metal or babbitt andlead, in which is seated the IOO lower walls of air-chamber J, closed above by a cover K, also having a continuous depression g similarly packed. Air-chamber J in the form illustrated is of oblong shape with half-round ends, its base E is fitted with suitable delivery-pipes L L, while the overhanging edges of its cover K and said base E are lirmly secured together by bolts M, passing therethrough.

N indicates the vertically-arranged vfront for waste-valve chamber C, indented upon its inner side by groove h for the reception of suitable packing material, in which the tapering walls of said waste-valve chamber are embedded and there retained by throughbolts i, headed upon the opposite side of the chamber in a surrounding flange j, extending therefrom. rl`his front N is broken by an outlet or port O, located at or about the center of 'chamber C and bounded by a suitable annulus k, constituting a valve-seat, while its upper end is equipped with a babbitted journal-bearing and slotted lid P, containing a short rock-shaft Q, for purposes which will now appear. p

Mounted upon shaft Q is an upright bracket Z, bolted to the horizontal angular end m 1of a pendulum-lever R and descending belou the port vO in front N, which it thus overlaps. Bolted to the lever R is a waste-valve stem S, its opposite end projectinginto valvechamber C through the center of port O, and upon said stem is fixed the waste or impetus valve, consisting of a concave cap T, a metallic washer U, and an interposed elastic valve-disk V, arranged to contact with its seat 7c when actuated. Screwed into front N, below its Waste-'valve port O, is a stud YV, loosely passing through aperture u at the lower end of lever R and in threaded connection with a hand-wheel X, the latter backed and adapted to be locked by a jam-nut o and serving to regulate tension upon lever R through an interposed reaction-spring p, surrounding said stud. Similarly above the port O in front N is fixed a screw-stud Y, upon the threads of which is 'adjustably mounted a thimble Z, carrying at i'ts outer end a fiexible cushion or buffer q, preferably of rubber. Buffer q therefore i'm'pinges upon the Linder side of lever R to regulate the throw of waste-valve V, is adjustable upon its stud or stem Y, and may be locked in a given position by the jamvnutd'r, provided for the purpose upon same stu This being a description of the invention in `one'f'orm of its construction, as illlustrated Y bythe accompanying drawings, its use and operation may be stated as follows:

V'ate'r from an elevated source of supply fiowing down a suitably-inclined drive-pipe enters the main pipe A, through which it flows, escaping from waste-valve port O, until the current gets in full motion, and is of suicient volume to close the waste or impetus valve V by rocking the pendulum-lever R upon its supporting-shaft Q against the action of its tension-spring p. The column of water thus arrested instantly enters valveports F F, now its only source of outlet, and bodily elevating check-valves I I overflows in all directions into the air-chamber J, finding a level below the horizontal plane of valves I I. Pressure upon the waste-valve V thus being relieved the latter is again swung upon its j ournal-bearin g P by the reaction of spring p until valve-lever R is stopped by the fixed buffer q, said spring p and buffer q acting similarly upon opposite sides of lever R to regulate the extent of its oscillations in each direction. Water now wasting or flowing from valve V temporarily drains ports F F, the valves I I whereof have been seated, and simultaneously with this action fresh air at atmospheric pressure is supplied to the ports through air-feeders G G, terminating immediately below the valves I I, respectively. These feeders G G are of tapering form, their inlets being of liberal dimensions and their outlets consisting of constricted lopenings II II, serving to inject a fine stream of air in one direction and in the opposite direction to practically prevent the escape of water. rlhey also will be seen to perform double and equally important functions with each stroke of the pump-that is to say, they not only equalize the air-pressu re in .ports F F, thus overcoming the tendency to vacuums and consequently facilitating action of the waste-valve mechanism, but with each upstroke of the pump the fresh air thus admitted to ports F Fis rst driven directly into air-chamber J, in which it serves to augment the pressure and more than compensate for that portion of the air constantly being freighted off in the water. The above action is repeated indefinitely, the waste and check valves acting, as stated, in rapid succession, both air and water being automatically forced into the air-chamber J at each stroke of the pump; and it will be noted that the ports F F are designed, arranged, and adapted to discharge into air above the normal water-line rather than into a body of water of greater density, affording a greater resistance, that acute angles are avoided, and that the general structure contemplates a pump easily cleaned and kept clean, and one which is entirely automatic in its action.

In a hydraulic rain, the combination with a supply-pipe, air-chamber and a waste-valve, of a flanged body cast integral with said supply-pipe and forming the base of said airchamber; ports extending through said body, communicating between said supply-pipe and said chamber, and adapted to discharge above the water-line of said chamber, valves on the top of the aforesaid body, inside of said chamber and adapted to open and close the said ports; flexible strips secured to the top ofthe valves and to the top of the said body, so that the said valves may have a vertical move- IOO IIO
