i* PUMP.

To @ZZ/whom t may concern#A I Be it known that I, JOHN T. S. BROWN, Jr., a citizen of the United States, residing at Prospect, county of Jefferson, andi State of Kentucky, have invented a certain new and useful lmprovement in Pumps, ofwhic'h the following is a speciication.-

This invention yrelates to improvements 'in pumps with particular reference tO'thatcla-Ss known as tube or deep well 'pumps. j-

An obj ect is the provisionofa pump which will deliver a constant streamv of water', thereby conserving the energy delivered tov the pump. v

A further objectl is'to produce a pump of` the class described which will be economical in construction, efficient in operation and du-` rable in service. A Y

With'the foregoing andy other objects in view, the invention consists ofthenovel ar-.

rangement and construction of parts, ill'ustrated in the accompanying" drawing,Which V forms apart of this specification, wherein is" set forth an embodiment of the invention,' but it isto be understoodt-hat such changes and modifications maybe resorted't'oxas come within scope of the claimsl appendedl here-l unto. -V

Referring to the drawing whereinlike reference characters designate` similar parts f in the several views: Figurel, isa, Centrala verticalI section, with portionsbrokenawayA and parts in elevation, yshowing the plunger near the completion of its downward stroke;

Fig. 2, a view similar to Fig. l, showing.. the plunger'near the completion of its upward travel; Fig. 3, a transverse section on line X-X of Fig. 2; Fig. l-a perspective of the guide ring; Fig. 5, ajpl'anofthelsidel valve spring.

Referring to the drawing, the reference characters -A-, -B--,. and;` --C- desigf nate respectively three portionsor sections# of the pump, z'. e. a working'` barrel, aV valve chamber, and a discharge tubewhichkare se-- cured together at their points .ofconiectionV in any of the usual wayslnownl to the, art.' The working barrel, is preferably con-- speeiacation of Letters Patent. Patentedrct. 19,1915..Y 'i limination'ieafnovember 181914. seriai No. 872,700. Y

inlet 6i-.V Nithinv the working barrel is ai' hollow piston, or plunger, +7- providedv with a'plurality of 'pistonrings -8-, which is open at the bottom and closedlat the top by an arch 9%. `,ln the linterior of the piston near the upper vend thereofis a septum flO; on the upper face of which isl a ball valve y`-ll-- which prevents a vdownward flow of fluid through an opening 'f-12,-. The rise of thevalve is limited by lugs 1B--l which extend inward from the archedl inclosure 9. Connected to the upper end of the plunger andv in connection. withA thel interior thereof, is a hollow piston rod ,-1e provided on its upper end' with suitablemeans for the attachment thereto of a pump rod -15- which extendsupward to a point o-f connection with asuitablejactuating force. In the side wallof thepiston rod, near the upperend thereof are a lplurality of outletsLj-lG-, the totalare'a' of which is substantially equal to that of `the opening arranged in staggered relationship so yas not to'w'eak'enthe rod.y kThe pumpfrod is pro-g' vided with side extensions, or -wings 17- adapt'ed tolcont'act'withfthe sides ofthe dis- Q i l charge tube to prevent-side lash ofthe pump 'Y Y 85 Ac plurality of inlet-openings, o-rports,

rod during the down stro-ke.l

-18- are disposed about the'walls of the valve chamber. The flow of Huid therethrough being controlledby valves ,--19-l each of which comprises a body portion 20.*` the face of which is contoured to conform tothe curvature 4ofy the walls of the chambei'and covered with a layer of suitabley pacl'ingmaterial such as leather secured thereto by metallic plates -22 The `val've'is carried on'the end of a exible member, @strap-23+. which is secured on an abutment, or. block, IThe valve `is connected1 with" the. strap by means Aof vpins 25- which` extend' through elongated of-l connection ibyallowing restricted vertical vmovement of the valve while 7preventing any lateral movement'thereof, facilitates the' `proper ,S'e-tnelof the valve. Thetor' ofthe block 24' iscurved transversely, relative to the strap. 23 and the strap is secured thereon by means ofI bolts ,.and 28-', which eX-y tendJv through the walls of the chamber,

through the Vblock v 274, emerging therefrom on each side ofthe crown of the curved top, andV through perforations -29- inv the w ioo openings 264 in the strap. u This method strap. A bolt which extends through Vthe Walls of the chamber and through a. perforation -31- in thestrap provides means .f

Vincrease the pressure exertedon the valve.

lt is to be understood that securing means will be used in connection with the bolts 27, 28, and 30, such as lock nuts, castellated nuts or other suitable means. Vlinmediately above the valves 19, an Vannular ledge 32- extends inward from the wall of the chamber and forms a seat for a valve. The ledge is spaced from the piston rod leaving a passage -38-- il sleeve -SSM' adapted to slide on the piston rod, has an annular enlargement S4-which rests on the upper face of the seat 32, and forms a cutoff valve which closes the passage 38 during the downward stroke of the piston. A ring .-35- disposed about the piston rod, and spaced from the sides of the chamber by lateral arms, or lugs, -36-, is secured in position by screws -37- and serves to limit the lift of the valve 34: and acts as a guide for the piston rod.

The operation ofr my improved pump is as follows: /Vhen the piston is Von the up stroke as illustrated in F ig. 2, the wateris drawn in through the foot valve filling the lower portion of the working chamber, and such of the water as is held in the chamber above the piston is forced up, its pressure serving to close the side inlet valves 19 and to raise the valve 34 on the piston rod, as shown, which operation opens up a free communication between the working chamberV and the discharge tube through the passage way -38-, it being obvious that during such operation the ball valve 11 will be forced back by the pressure of the Water Y valve 84 which is held closed by the weight to close the port l2 in the upper end of the plungerv 7. -When however, the piston is forced down as indicated in Fig. j l, the pressure will close the foot valve and force the water beneath the piston up therethrough lifting the ball valve 1l and passing through the openings 1G, in the side of the piston rod, into the discharge tube C. lt Will be Aobserved that yduring this operation the water inthe discharge tube will be prej vented from entering the upper portiony of the working chamber by closing of the slide At thesame time the upper part of the chamber is refilled through the sidevalves 19. It will be seen that a continued flow of Water is maintained through the discharge tube of the Water pressing down thereon.

during the operation of the pump. It is to be understood that the side inlet valves may be placed in an integral extension of the working chamber, instead of a separate ,sectionl as illustrated, vWithout departing from the spirit of the invention. It will be observed that the arrangement illustrated permits of aready removal of parts for repairsand adjustments.

. It is thought that the many advantages of my invention may be readily understood from the` foregoing description,and that anyone skilled in the art may make and use the same, and
