p p 4 i ,To all. whom it may concern,.- l vBeitknown thatI, JAMES W. MYER, a citi. Zen yof `the United States, residing at San Dieg`o, in the county of San Diego and State 5 fof California, have invented certain new and useful Improvements in Pumps, of which the following is a specification, L .p n lMy lpresent invention pertains to pumps,5 ,V and re ates more particularly to an improved ro mechanism for eecting a continuous dis-i .charge therefrom. p, v The inventiony is illustrated in the accompanying drawings., wherein-f, Figure 1 is a front face view of the mechan-` ism; Fig. 2, a sideuviewy thereof; Fig.` 3, ai;
,transverse horizontal sectional view, the* l-main drivingshaft and driving-pinions being, shownin full lines; Fig. 4, a side elevation of 1 one of the jacks or lifting-'heads as seen from' Fig. 5 atransverse vertical; `Sectional viewthereofj-Fig. 6, 1a horizontal v.sectional ,viewl on the line of., Fig. l; and?- Fig. 7, a detail, view of a portion ofone of the lheads kand drivingpini r ns,.l the retaining:
z 5 block or section being removed,v D v The obj ect of my invention is to provide a simple, strong, and effective mechanism for imparting a differential .movement to the pisy `ton-rods of a` double-acting pump, aquiclry godownward movement and a relatively slow; upward movement ,being imparted to. the
rods, whereby ,a constant iiow of water from,
the ump is obtained. ,i I? ,o
Tlie pump proper forms no part of the pres-g I. 3 5 ent 4invention-and any well-lrnownconstruc- Y ltion may be employed. ,i
. v he main frame is preferably'forrned of a single casting comprising -a base platei -or v ,flange A, surmounted by a substantially. U-l
4oshaped body B, theforward edges of which; are provided with iianges C C, forming ,Ways or guides.v lilxtendingl upwardly from the two columns D D,'which form the support for -the main" driving-shaft E. A drivingpulley F, preferably a split-wood pulley, is secured to said shaft Eby a split lflange orV hub G. Upon each end of the shaft E is secured a pinion H. A roller l is'mounted on 5o the shaft immediately adjacent to each of the pinions, while a similar though somewhat smaller roller J is mounted upon each end of the shaft, being retained thereon by a collar K, pinned to the shaft.
A jack or pumping-head is designed to cooperate with each pinion, the jacks being so moving down as'the other is elevated, and vice Aversa, lnasmuch as the two Jacks or heads are the same 1n construction, a descrip- 1 positioned that they work in alternation,ione
tion of one is deemed ,suflicient herein. IEach headv comprises a casting having a substan-l tially triangular body with one vertically-dis posed side andv a v,relatively long depending arm L. i Said headv isformed interiorly with a ,groove or channel M, a track or runway .N for the roller J, and a recess O for the reception of the retaining-collar By the formation `of. the .channel M4 aninwardly-projecting `flange Pis produced upon which roller l bears and runs. v
.In th form illustrated a centrally-disposed member Q is bolted to the head, a rackRfbeingformed upon saidymember and extending `entirely around the same immediatelyopposite the channel M.
...with iange Py and roller I, thelatter. bearing vdirectly thereon., ,A l.
As willbe seenupon reference to Fig.'A 5,'the flanges P and S. prevent the withdrawal ofthe pinionfroml-the head, land the pinion is heldl in meshswith the rack R by the .-rollers I and'iJ. To permit the insertion andwithdrawal 1 of the pinion from the head orj aclr, the flange P is cut. away at one side, (see .-Figs. 4 andI 7 Thehead is likewiseproy ,videdwith a flange S, which; stands/inline:
Sol
thereby forming a recess ,T-. Normally this .r.
,recess isfclosed by ablock U,-held inplaceby -.bolts V, which pass through-theblock andthe The lower end ofthe*arm'lllion.eachy y jacks or heads is secured to a slide orframe, l.
Awhich in .turn .is`v corinectedfto the piston-rod fof .the pump. vvBotlrofthese y.slides Aare the same in construction except as tothe man- '.ner in which they are .connected .to the piston'- Vrods.
Extending. outwardly from. the Aupper por.- tion of ,thecolulmn D :isa llug or ear -A .slide X, preferably of iron. vor steel, bears difference will be hereinafter setA 1 forth. body as a continuation of the flanges are ICO against said lug crear and a roller Y, securedj to the column .opposite said lugfor'earn Jlhe .slide-passes between .the roller .and-.the ear,
and by reasonof the pivotal connection of the lower end of the arm L and the slide being upon the outer side of the latter the upper end ofthe slide tends normally to bear inwardly against the roller. The pivotal connection between the arm and the` slide is effected by a bolt Z, which passes through an IIO opening formed in the lower end ofthe arm.
The slide at its lower end is formed with a finger A', which passes in rear of the flange C, and acting with a similar nger B, extending around the opposite side of the flange, (see Fig. 6,) serves to hold the slide directly against the forward face of the iange. The slide also carries at its lower end an antifriction-roll C', which bears upon the inner edge of the fiange and assists in maintaining the slide in its pro er relation, at the same time preventing un ue friction between the parts.
The slide X (shown at the right in Figs. l and 6) is provided with a bifurcate'd or U- :shaped arm or cross-head Di, to which are attached the piston-rods Ey The lefthand yslide is provided with a single arm or cross-head G', which passes between the y.bifurcated `ends 'of the arm D and is con- 'f-'nec'ted to a singlecentral piston-rod H The slides will therefore pass each other Without interference and the ydouble pistonrods, which are connected to one piston or plunger lof the pump, be moved up or down in opposition to the movement of the single pis'tonrod lconnected to the yother plunger oi theY ump.
In t 'e operation of the pump the pulleywheel moves the Idirection indicated by the arrow in Fig. 2, which will impart to the ldriving-pinion y'carried by the shaft E a inoltion in the "direction of 'the arrow shown in Fig. 4. As the head or jack moves down, carrying with it the `cross-arm, to which is attached yone of the piston-rods, the pinion will pass-along the vertically-disposed side fof the rack R. Immediately the pinion passes the -upper end of the rack it wili begin 'to lift the head -or jack. Inasmuch as the rack is provided with two inclined faces which must travel over the pinion in the act of raising the'head -or jack, the upward travel `of the `"latter will be slow las compared to its downward movement.
Since the `jacks work vin opposition to each ioth'er,-one will at all times be moving upwardly, and a Iconstant stream o'f water is therefore ejected from the pump.
Having thus described my invention, what I claim'isl. In combination wit'hthe piston-rods of 'a pump, la 'driving-shaft a pinion carried by each end of said shaft; and a jack or head for 'each piston-rod, each of said jacks being -connected to lone of said rods and provided with 1a rack which meshes with one of the pinions carried by the drivir-xg-shaft, said rack lhaving 'a substantially vertically disposed portion and two inclined portions, whereby each jack will be moved down as the pinion works `over the vertical portion of the rack.
2. In combination with the piston-rods of :a pump; a frame located adjacent thereto;
a power-shaft carried by said frame; a pair of ways or guides carried by the frame; a slide mounted upon each of said ways, said slides being connected to the rods; a pair of jacks pivotally connected at their lower ends, one to each slide; a pinion carried by each end of the power-shaft; la rack carried bv each ack, with which the pinions mesh, each of said racks having a substantially vertically disposed portion and two inclined portions; and means for preventing the withdrawal of the pinions from thejacks.
3. In combination with the piston-rods ol' a pump, a frame located adjacent thereto; a power-shaft carried by said frame; a pair of ways or guides carried by the frame; a pair of slides, each extending substantially the length of the ways and connected, respectively, to the rods ;.means for guiding the upper end of each of said slides; al pair of jacks, one for each slide; pivotal connections between the lower end of each jack and its slide a rack carried by each jack, said racks being triangular in outline, with one face or stretch in substantial a'linement with the piston-rods; anda gear carried by each end of the power-Shaft, said gears meshing with the racks, substantially as described.
4. In combination with a piston-rod of a pump, a slide connected to the rod; a jack pivotally 4connected at its lower end to the slide; said jack being provided with an interiorly-formed channel M, a track yor way N, a recess O, and oppositely-disposed ribs or flanges P and S; a rack carried by the jack, said rack standing yopposite the channel M; a power-shaft a pinion carried by said shaft, said pinion being of a diameter greater than the distance between the opposing faces of the flanges P and S; a roller 'carried by the outer end of the shaft in line with the track or wa N; a second roller I carried by the shaft intermediate the flanges P and S; and a removable block secured in a recess or opening formed in the periphery of the flange P.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
