ROD AND TUBE ELEVATING AND PUMPING APPARATUS FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 713,269, dated November 11, 1902.

Application filed August 13,1901. Serial No. 71,960. (No model.)

Referring now to the accompanying draw- My invention seeks to provide a certain ings, in which like numerals and letters indi- 9o novel and economical arrangement of parts cate like parts in all the figures, 1 designates adapted when combined with the ordinary an oil-well derrick, 2 the samson-post, 3 the bull-wheel and rope-winding shaft and the walking-beam, 4 the bull-wheel, and 4 the band-wheel standards to effect the required bull-wheel shaft, all of which may be of the operation of rod and tube raising and pumpwell-known construction, as they per se form 5 ing in a more expeditious, convenient, and no part of my invention. economical manner than has heretofore been 5 5 designate the posts, upon which the accomplished and in which a small-power usual type of band-wheel shaft is mounted.

On these posts is journaled the shaft 6, which is belted with and driven reversibly from the engine, as will presently be more fully explained. Upon this shaft is mountedagroove or band Wheel 7, which serves as a substitute for the grooved rim usually a part of the ordinary band-wheel, and this wheel is connected by an endless rope with the bull-wheel 4,the rope in my arrangement beingastraightway one and not crossed. Upon one end of the shaft 6 is mounted a large gear 8, preferably of the same diameter as the wheel 7. (See Fig. 3.) The gear 8 meshes with a cogpinion 9 on a stub-shaft 10, one end of which has a bearing in member 11 of the bracket 11 on the adjacent post 5, and the other end is journaled in the outer end of the anglebracket 11, the special form of which is shown in detail in Fig. 5.

By providing a bracket of the character described the stub-shaft 10 can be conveniently supported on the usual post 5 without requiring any material change thereof. Upon the shaft 10 is mounted a ditferential pulley 12, and the two different-diam eter band-surfaces are held in alinement with a corresponding differential pulley 13 on the gas-engine driveshaft 14.

The large gear-wheel 8 has one of its arms 8 provided with a series of apertures 8 for adjustably joining with it the lower end of the pitman 15, the upper end of which is pivotally connected to the outer end of the walking-beam in the usual manner. The lower end is attached to the arm 8" by the usual pin device 8, as shown.

G designates a gasengine of any approved type. In my complete construction of well preparing and pumping apparatus the bandpulley 13 is loosely fitted upon the drive-shaft 14, and it has a clutch-flange 13.

14 is a hub-piece fixedly held on the shaft 14, with which a set (four, more or less) of clutch-arms 16 16 are pivotally joined, and said arms have a toggle connection 16 with a clutch-sleeve 17, slidably held on the shaft 14, by proper shifting of which the arms 16 are made to engage with the flange 13 to lock the pulley or wheel 13 to turn with the shaft 14 or disengage said flange 13 to permit the pulley 13 turningloosely on said shaft.

18 designates an internal gear-rim fixedly connected to the pulley 13, with which is held to mesh a gear-pinion 10 on a short countershaft 20, mounted in suitable bearings and which carries a small cog-gear 21, loosely mounted thereon, which meshes with a larger cog-wheel 23, fixedly mounted on the outer end of the engine-shaft 14. The wheel 21 has a clutch-face 22, adapted to be engaged by a clutch-sleeve 24, slidably held in the shaft 20 and held under control by a clutch-lever 25, which lever has two arms 25 25 one of which connects with the clutch on the main shaft 14 and the other with clutch 24 and is pivotally mounted in such manner so that when shifted to the limit of movementin one direction it will set the clutches 16 to engage and lock the pulley 13 to turn with shaft 14 and disengage the gear 21 to allow the gear 21 to run loose, and when shifted to the other direction it will reverse the position of the clutches and provide for imparting a reverse motion to the pulley 13 through the shaft 20, gear 19 21, and the internal gear 18 on the pulley 13. Vhen shifted to a central position, the lever 25 sets both clutches to an intermediate or an inoperative position, and thus cuts out the shaft 6and the pumping or tube-lifting devices to leave them at rest while the engine still runs, thereby avoiding the loss of time and the inconvenience of having to start the engine every time the pumping mechanism has been stopped.

From the foregoing, taken in connection with the accompanying drawings,it is thought the complete operation of my invention and its advantages will be readily apparent. By reason of the straightway connection between the bull-wheel and the wheel 7 wear on the drive-rope and danger of breakage are reduced to the minimum, and by reason of the reduction of friction at this part of the apparatus less power is required for operation.

By joining the shaft to the engine in the manner shown and described the band X can be shifted to impart. a high or low speed to shaft 6, and by reason of the simple and convenient manner in which a reverse motion can be imparted to the shaft 6 during the unidirectional motion of the engine-shaft the operation of reversing the movement of the tube and rod lift-rope can be effected quickly and with greater positiveness than is possible with the old method before referred to. Again, by reason of the reversibility of the shaft 6 or cutting it out entirely the reverse action of the shaft 6 can also be readily utilized to assistin retarding the movement of the lift-rope in either direction. One of the essential advantages of my invention lies in the novel manner in which the several parts constituting my invention are arranged, so that they may be readily attached to the ordinary pumprigging and to an ordinary gas-engine without materially changing their present construction.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a mechanism for oil-wells of the character described, the combination with the band-wheel-driving devices, consisting of the pulley 12, the shaft 10, the bracket 11, the

gear 0, on shaft 10, the gear 8 meshing there-.

with, and carried by the shaft 6, and the bandwheel 7, also carried by shaft 6; of the engine-shaft 14, the pulley 13, loosely mounted thereon, belted with the pulley 12, gear connections, connecting the pulley 13 with shaft 14, and clutch mechanism for shifting the said gear connections into an operative position to rotate the pulley 13 on the shaft 14, and for locking the said pulley 13 to rotate with the shaft.

2. In an apparatus as described, the combination with the engine-shaft l4, and the drivepulley 13, loosely mounted thereon; of a supplemental drive-gearing engaging the pulley 13 and shaft 14, said supplemental gearing consisting of the pulley 12and the pinion 9, both carried by the shaft 10, and the shaft 6 carrying the drive-wheel 7, and the gear 8 scribed, the combination with the drive-shaft 14, having a fixedly-held gear 23, and the pulley 13, loosely mounted on said shaft 14, said pulley having a clutch-flange 13*, and an internal gear 18; of the supplemental shaft 20, having a gear 19, held to engage the pulleygear 18, the clutch -faced gear 21, loosely mounted on shaft 20, and held to mesh with drive-gear 23, the clutch 24 on shaft 20, the clutch devices on shaft 14, for cooperating with the clutch-flange 13, on pulley 13, and an operating-lever for shifting the clutch devices on the shafts 14 and 20 in unison but in reverse directions, for the purposes described.
