Application filed June 2,

which is so arranged as to transmit power, from the engine to the pumping or hoisting apparatus of the well so thatthe maximum speed and horse power of the engine may be secured, so that the pumping operation may be converted into a hoisting operation and so that slow speed of pumping may be con verted into high speed of hoisting without reducing the effectiveness of the engine.

It is my object to provide a unitary apparatus which will permit of using a very much shorter belt from the driving pulley to the band wheel, thus shortening the length of the belt and engine house and the size of the foundations. 1

It is my objectto provide a single power transmission unit, which because of its uni. tary nature, will maintain its shafts in alignment, will permit of the. reversal of the direction of movement of the belt on the,band' wheelat any speed, all of which can be secured by a single movement of a single control rod. o

In detail it is my object to secure this result by the use of a single, relatively short chain from the engine to the intermediate apparatus of my invention, the driving chain being so arranged that it will always continue in motion inthe same direction at the same speed, but upon moving the single control lever, the apparatus will be braked, the clutches shifted and the power diverted from the slow speed mechanism to the high speed mechanism, the single master driving chain being adapted to actuate both mechanisms.

Heretofore, considerable difii culty has been experienced in providing adequate clutch mechanism between the engine and the driving mechanism, due to the fact that the'long belt to the band wheel, some fifty feet in length, in addition to the strains of driving, not only put considerable strains on the clutch and brake mechanisms, but resultcd in pulling shafts out of alignment, warping. bearings and injuring the wrist pin connections of the piston rod with the shaft.

My present invention not only eliminates these difficulties as the clutch, reverse and,

brake mechanism are removed from the engine, but also provides a shorter belt with a larger driving surface for the belt, thus securing greater efliciency. It is also possible to nowmaintain the engine .at its maximum speed and horse power without the loss heretofor occasioned due to the use of the previous methods of reversal. A larger pulley can be used to increase the belt contact, the

belt house can be reduced in length and the alignment of the parts is insured by mounting all the parts which are subjected to any strain upon a single base casting with short shafts thereon supported in heavy bearings.

Referring to the drawings in detail, 1 is an engine having a fly wheel 2 and a shaft 3 upon which shaft is mounted a sprocket 4 actuating a master driving chain 5 which is mounted upon themasterdriving sprocket 6 turning in the direction of the arrow. This sprocket 6 is mounted on the driven shaft 7 The chain 5 rests upon the reverse sprocket 8 which'is carried on the reverse 'and turns therewith.

a rectangular, single, integral supporting base. The bearings supported thereon are mounted in the usual columns 13. This master driven shaft 7 carries on it not only the sprockets 6, which is loosely mounted thereon, but also the clutch generally designated 14 which fixes the sprocket. 6 on the shaft, when desired- The shaft 7 carries the driving pulley 15 which is fixed thereon The shaft also carries the brake drums 16, which turns therewith beneath the brake band 17. The right hand of the shaft 7 carries loosely thereon asmall high speed reverse sprocket 18 and a clutch The reverse shaft 9 carries on one end the driving reverse sprocket 8 which is fixed thereon on the left hand side and the companion reverse sprocket 20 on the right hand side which is fixed on the shaft 9. This shaft is carried in the usual bearings on the columns 13. Achain 21 is mounted upon the sprocket and the sprocket 18. The control mechanism for alternately having slow forward driving for pumping and fast reverse driving for hoisting is arranged and operated as follows.

A master control rod which leads to a place adjacent the operator is designated-22. This rod extends to a point approximately midway the base casting where it is pivotally connected to an upstanding arm 23 pivoted on a stub shaft 24 supported in bearings 25 which are mounted in supports 26 on the base casting 12, This arm 23 is adapted to rock the shaft 24. On this shaft is a brake arm 27 being pivotally connected at 30 to a lever 31, which lever in turn is pivoted upon a bracket mounted on the base casting. This bracket is designated 32 and the lever 31 is pivoted thereon at 33. The lever is extended into a second arm 34 so that the two arms form a bell crank. The free end of this arm is connected at 35 to the moving arm of the brake band 36. the other end of which is pivotally fixed at 37 on the supporting frame.

Returning to the shaft 24, it will be noted that it is provided with a bell crank having arms 38 and 39. The arm 38 is connected by a link 40 which is pivotally mounted thereon at 41 to a bell crank 42 which is pivotally mounted on the base casting at 43. This bell crank has attached to it another rod 44 which is the clutch rod for the reverse mechanism. This rod 44 is pivotally mounted to the bottom of a lever 45 which in turn is pivotally supported at 46 on a bracket 47 on the right hand side of the machine. The upper end of this lever 45 terminates in a jaw 48. The jaw is mounted between the shoulders 49 which in turn are mounted on a sleeve 50 carrying the movshaft 7. The left hand movement of the clutch will bring it into engagement wit-h the engaging face of the clutch member 19.

Returning to the bell crank arm 39, it will be noted that there is pivoted thereon at 52 a link 53 which is pivoted at 54 to the bell crank 55, which is in turn pivotally mounted at 56 upon the base 12. The other arm of this bell crank is connected to a link 57 which is the forward driving clutch link. This link is pivoted at 58 to the shifting arm 59 which in turn is supported on the bracket 60 at 61. The upper end of this arm 59 terminates in a yoke 62 working within spaced collars 63 on the sleeve 64 on the shaft 7. This sleeve carries the clutch 65 which serves to connect the pulley 6 with the shaft 7 or disconnect it.

The remainer 0f the mechanism is of any conventional type. The pulley wheel 15 drives the belt 65 on the band wheel 66 which has connected to a crank 67 a stirrup 68 which in turn is connected to the walking beam 69 mounted on the Samson post. The

free end of the walking beam is connected to the pumping mechanism generally designated 71 within the derrick 72. The band wheel is supported on the' ack post 73.

Method of operation.

The engine 1 runs continuously driving the chain 5. This chain 1n turn drives the sprocket wheel 6 continuously and the small reverse sprocket 8, such sprockets turning in opposite directions. The sprocket 8 is I lixed on the shaft 9 so that the shaft 9 also turns continuously. The sprocket G, however, is mounted loosely on the shaft 7. When the sprocket 6 is clutched to the shaft 7 through the clutch 65 the shaft is driven forwardly at low speed for the purpose of pumping. loose upon the shaft 7 and the clutch 51 is in its disengaged position. The sprocket 18 is turning in the reverse direction because it is connected by the chain 21 to the sprocket 20 which is mounted on the shaft 9.

When the operator desires to reverse, he moves the rod 22 rotating the shaft 24 thereby applying the brake 17 opening. thev clutch 65 allowing the sprocket 6 to turn loosely on the shaft 7 and closing the clutch 51 connecting the sprocket. 18 to the shaft 7 toturn the shaft in the reverse direction with the sprocket 18 which is being driven by the'chain 5. sprocket 8., shaft 9. sprocket 20 and chain 21. verse drive due to the sizes of the parts. It is thus possible for the operator withoutdisturbing the engine or its speed or dccreasing the effective horse power therefrom and without shutting down his equipment by one movement. to shift from slow speed forward pumping position to high speed reverse hoisting position.

At this time, the sprocket 18 is This is a high speed reessee"? When it refer to chains and sprockets, it will he understood that l. comprehend within my invention other forms common in the art of driving mechanism. ll use these definite terms for the purpose of convenience and not for the purpose of limiting myself to the detail'mechanism specified, as it is obvious, under some conditions, belts, gear trains or equivalentmechanism may be used for driving.
