PUMPING APPARATUS.

Application filed March 39, 1923. Serial No. 628,784.

To all whom it may concern:

Be it known that I, OswALD J. TURNsEK, a citizen of the United States of America, residing at Stuttgart, in the county of Arkansas and State of Arkansas, have invented certain new and useful Improvements in Pumping Apparatus, of which the following is a specification. My present invention relates generally to pumping apparatus, and more particularly to pump heads, and proposes a pump. rod actuating mechanism by means of which a long stroke reciprocating motion may be developed having special advantage both in regard to the actuation of the pump rod in use and to the maintenance of the pump and the actuating parts against undue wear in use as well as rapid deterioration between periods of operation, myfurther object being the provision of a compact structure which is readily accessible to and easy and quick repair and substitution of parts as well as an apparatus which readily lends itself to encasement topermit of the run ning of its main components in a fluid lubricant.

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure 1 is a front elevation showing my improved pump apparatus, with the front plate of the casing removed,

Figure 2 is a side elevation,

Figure 3 is an enlarged perspective view of certain. parts removed,

Figure 4 is a detail perspective view of a portion of one of the actuating chains, and

Figure 5 is a longitudinal section through the pump rod and its sleeve showing the trunnion connections thereof.

Referring now to these figures and particularly to Figure 1 I have shown my improved apparatus in connectlon with a pump casing 10 havlng therein upper and lowerv plungers 11 and 12, working in opposition to one another, both of these plunger-s being valved and the lower plunger 12 being mounted upon the lower end of the pumprod 13, while the upper plunger 11 is mounted upon the lower end of a sleeve 14 around thepump rod and through which the latter is movable. V

I havev also shown the pump casing 10 with a Y fitting 15 at its upper end, the breed 91 which term the outlet, and.

the upper end of the main section of which supports a stufling box and the like 17 upwardly through which the sleeve 14 or rather also includes side walls 25' formed by the upper portions of side frames 26. These side frames are securely mounted at their lower ends upon the side portions of a base plate 27, the latter of which surrounds the stufling box at theupper end of the pump casing so that thevertically shiftable pump rod and its sleeve will not only be guided in their movement above the ground level or the upper end of the pump casing, but a frame will be formed which, by the addition of front and rear walls in connection with the side walls 25 and the vertically spaced top and bottom plates 23 and 24, become a casing wherein the pump rod andsleeve actuating parts may, to a considerable extent, be completely housed and provision likewise made for the running of these parts in a fluid lubricant. H p

' To this end the side frames 26 have side bearings 28 for a transverse driven shaft 29 able source of powerp This shaft 29 has upon its outer portions, outwardly beyond thebearings 28,small pinions 30 in engagement with comparatively large gears 31 secured upon the outer portions of stud shafts 32 mounted in bearings 33 upon the side walls 25 of the casing and also extending inwardly through these side-walls and pros videdwith inner sprockets 34 around which the lower portions of flexible chains and the like 35 extend.

The upper sleeve section 18 has an elongated vertical slot 36 above the upper end of the pump casing, through which a trunnion 37 exte'ndsfrom an attaching plate 38 securely bolted as by means of bolts 39 shown in Figureb, to the upper rod section so, eaidattaching plate -38-" and. saidrod.

,posite sides of the upper-portion of the section being provided With relatively engaging cross lugs and slots.

Diametrically outstanding therefrom with respect to its slot 36, the upper sleeve section 18 has a trunnion 4L0 projecting from an attaching ;plate 41 "which latter is securely riveted to the sleeve as shown in Figure 5.

As seen particularly in FigureS't-he trrlnnions 37 and are securely fastened to the horizontal hearing end portions '42 of a pair of horizontally disposed cross heads 43 "and 44, whose opposite ends have vertical bearingporti'ons 45 disposedon and slidahle in connection with a pair of upright guide rods 46, disposed laterally spaced relation "and secured at itheirupper and lower" ends through the top and Ebnttom plates 23 cand' fle. p i v IE ach' of the cross heads 43 and fe l has :an "internal slide lbl'ock 47mm B le "therein at right angles to the line of :-movement o-1'" pumprod, and each cross head also has a det'a'chab-le rail .48 above its slide :block wherehythe latter may heireadily reached, and wear compensated for; Each slide block 47 has an opening 49, and each of the actuating chains 50 includesin its length a pin block 51 having a laterally projecting pin '52 x as most plainly seen in Figures, which pinlis journaled. in the fresp ective slide loloclropenin-g 49.

The chains 50 which ZLIQzlDOSllZlOllGdiQt oppump rod and its sleeve, and the'lower portions of which extend around the beforeme-ntioned sprockets .34, have their upperv ends extending around sprockets'53 upon the inner endsof sh'afts h journaled through willzbe alternately the side plates 25 of the'casingzand through bearing :mernbers "55 secured .tothe. side walls. I

It is thus obvious that are rotated the cross heads ABJand 44 will .be raised and lowered oppositely with refspect :to oneanother and correspondlng movements communicated .to the pump'rod and its sleeve whereby the pilungers l'l and '12 shifted toward and away from one another. v

The major porti'oniof :therqperating parts,

' that is including the chains 50 --and their connections whereby they impart along ,stroke movement to; the pump $96. and its s sleeve, are located Within the leasing and between ithei top .and bottom plates .23 land :50 that these 1 parts may conveniently run in oili-andjgyet remain readily accessible for purposes of repair and substitution of parts, these disadvantages being supple- :mecntal to-and beyond the more .iinip'ortant advantages resulting from i the [application :tectiveness, aniieeflieiency sinfop erationandat the same time materially increase the strength anddurahility ofthe several parts and promote an apparatus which will be economical in first cost and practically eliminate the expensive upkeep of pumping app aratus now in common use.
