nELT-r'mHTENEn son PUMPS.

To all whom it may concern 1 lie it known that 1. Maunox 1C. Tana),-

a citizen of the United States. residing at ll'miston, in the county of llarris and State of 'leXaS. have invented certain new and useful Improvements in Belt-'ligliteners for 'lumps. as set forth in the following speci- 'lit'ation.

"This invention relates to belt tighteners 1or pumps and 11 has reference- |)1'H1Iill'll to "the provision o1 a morahleplunp head by means of which the vertical axisof the pump shattmg may he varied so as to adjust the lension-olr the drlvln l belt.

The foregoing. together with such other objects :as may hereinafter appear or are incident to my invention, 1 aitain by means of a couslruction which] have illustrated in profound form in the accompanyingdrzuw ingsr wherein @Fi m-e 1 isa sectional Viewillustrating the application of my invention to a well pump: and Figure 21s a perspective show ing of-the mo vahle portion of the pump. head. I.

- In order that a hotterunderstmnling may he] had of my invention, I will first describe I the form of pump mechanism which lhavie showman the drawings in order to afford a specific illustration ofthc application of my invention. The well chamber 7 is, 'n-ovide1l T with the usual well chamher casing 8 whi1'h is closedht the" top by means of the. ,pump

head hereinafter to be" described. The pump shown-1s of the; centrifugal type and com 'n'ises the runner easing 1) wh ch is adjilstably' supported in any desired position in the hottom of the well by means of the. p'ipc or discharge cas1ng'10 through which the water is elevated. "Within the discharge 1' casingYIO is the line shaft or piiinp shaft 11 which turns the runncrhladesj .1n the easing 9, the shaft 11 being inolosed in a line shaft casing. 12 provided for purposes of lubricatirm and support. At a T'pl'ural ty of points throughout the line shaft casing the shaft ll 'is provided with bearings 13, the

casings being broken away in the drawings The pump head comprises thc'plate 14 which is bolted to .the foundation structure 15 surrounding. the well chamber and provided in its-central portion with a slot 16, and the movahleplate 17 which is provlded with the centrally located downwardly projectlng threaded flange 18 into which the upper -I-*' Specification 0!

portionof the discharge casing is. thread-.

rd. The plate 17 is providedwith four slots located adjacent the corners of the plate and. through which thebolts 20 whichfasten V the plate 17 to the plate 14 pass. .The plate 14 :21 with which the edges of the'plate 17 have lsliding engagement. Adjacent one e111l,1l1e

plate l-Lis provided with the upstanding lug the shank of which is threaded at its extremity and has threaded enga "ement with a .'milar upstanding lug .24: Tormed on the 1 plate 17. The line shaft 11 is provided at t1;

top with the usual drivingpullcy 25 around which passes the drivingrhelt 26, driven from the engine 27. The engine frame may he bolted to a foundation ,15 in the usual.

.nianner. In ordinar practice, the runner casing 9 is of a diameter usually three 0r more lDCllQS'lQSS than the Internal diameter; of the well chamber casing.

In order to adplst the tension on the driving belt 26, the operation is as follows: .The'

runner casing 9 may be shifted approxi mately an inch and a half tqeither' side of the center line of the well cas ng with a corresponding increased range of movement at the top of the pump casing-at the pump head and it, has been. found 111'; ractice that a' three inch m 'ement to eit center lineoft ell cas head has been 611,111 to be-en 1 rely ractical merit which does not interfeiowith the successful driving ofe' pump shaft. The

"is provided with grooved guideways'o'r ribs in which is rotatably mounted a bolt 23 er side of the 1 at the pump" slight .angularinclination' of the 'dischar e casing'is not suflicient to cause any troub e, and it will be apparent that inasmuch as the line shaft. 11.'is supported at a plurality of; points throughout the length of'thecasingline shaft. and, the whole is self-contained and supported as a unit, the line shaft will at the pum head will notcause anyfbinding of" the opemtingpartst. A

and to afford a siiflicient re ugee adjusts i not bowpr sag; and therefore the adjustment .1

It will be clear that the device is sim 1e and easy to manipulate and is capable of a considerable range of adjustment such as to meet all ordinary conditions of service. The device is of considerable advantage inasmuch as it is'a dillieult matter to provide for adjustment of the'belt, owing to the weight not only of the engine, but also of the pump apparatus. It will be'obviousthat the force required to move the top of the pump casing will be crnnparatively small. clear also-that the plate or frame 14 will be securelyv held in .position not only by its bolts, but also by the downturned annular flange 28 which engages the inner surface of the well casing 8. l

That I claim. is: 1

1. In a well mechanism, the ron'ibination of a pump shaft; a belt for driving said shaft, and a pump head carrying the shaft, said head being movable to adjust the tension on the belt. 4

2. In well mechanism, the combination of a pump shaft. a belt for drivi ngsaid shaft,

:1 pump head carrying theshaft, and-means for shifting the pump head to adjust the tension on the belt. i

- In \vell inecl'ranism, the combination of a pump shaft; a belt-for driving said shaft, an engine for driving the belt, and a pump head carrying the shaft slidablyi mounted for adjustment toward and fromfthe engine to adjust the tension on the belt.

4. In well mechanism, the combination of a pump-shaft, a relatii'ely fixed engine, a driving belt, and means at the top of the well for shiftingthew-eriical axis of the shaft to effect adjustment of the tension of the belt.

In well mechanism theeombination of 8. In well mechanism, the combination of It will be' a pump shaft, a drivin belt therefor, and an adjustable support or the pump shaft, comprising a relatively fixed plate, .a second plate slidably mounted on the fixed plate and and carrying the pump shaft, and a horiv zontally disposed screw for adjusting the second plate with respect to the fixed plate.-

S. in well mechanism, the combination of a pump shaft, a belt for driving the shaft, and an adjustable pump-head carrying the shaft and shiftable to vary the tensionoon the driving belt, said pump head comprising a relatively fixed plate provided with guide ways and having an aperture of larger dimensions than the shaft, a second plate slidably mounted in the guide ways'and carrying the shaft, means for releasably fastening the second plate to the fixed plate, and a screw'. carried on the fixed plate and having threaded engagement with the second plate.

9. 11:, well meehanism,the combination of a pump shaft, a belt for driving said shaft,

, a pump head carryingthe shaft, a support,-

t'or thepump shaft, comprising a fixed plate and a plate mounted to slide on said fixed plate and carrying the shaft, and a screw for moving the said sliding plate back and forth. with respect to the fixed plate to vary the tension of the driving belt.

In testimony vvhereof I have hereunto signed my name in the presence of two subscribing witnesses.
