POWER-TRANSMITTING MEANS.

Specification of Letters Patent.

To a/ZZ whomJ 7115 ntctg/ concern:

Be it known that I, VILLIAM D. GOFF, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented a new and useful Power- Transmitting Means, of which the following is a specification.

This invention in one aspect relates to means for converting rotary into reciprocatory motion, and while particularly useful as pum -operating mechanism is undoubtedly capa le of successful employment for other purposes.

One of the principal objects is to provide novel means of a simple nature whereby rotary driving power is converted into reciprocating motion for operating a plurality of reciproeatory memb ers-as,for instance, pumpplungers-the said members being so arranged that they practically balanee each other, and thereby eliminate to a great extent the shock due to the change of direction of movement.

A further wobject is to provide mechanism wherein either reciprocatory member can be disconnected from the driving means and to provide means that can be arranged to act as a counterbalance in place of the member so disconnected, the eounterbalancing means being also disposed so that it may be made to act in case the members do not of themselves eounterb al ance.

The preferred embodiment of the invention is illustrated in the accompanying drawings and is in the form of pump-operating means.

In the drawings, Figure 1 is a perspective view of the mechanism. Fig. 2 is a side elevation of the crank connections between the driving and driven elements and illustrating their action. Fig. 3 is a plan view showing the clamping means for the well-easings. Fig. 4 is a vertical sectional view through the rock-wheel. Fig. 5 is a top plan view of the same. Fig. 6 is a cross sectional view through the counterweight and its support.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a suitable frame 7 is employed, comprising longitudinal and cross beams bolted or otherwise secured together. On one end of the 'frame is journaled a driving-shaft S, that isdisposed transversely of the frame and carries at one end a driving-pulley 9 and at the other end a crankarm 10, provided with a series of openings 11. A fly-wheel 12 is preferably mounted on the drive-shaft between the longitudinal beams of the frame. A rock-shaft 13 is journaled transversely on the other end of the frame and carries at one end a crank-arm 14, said crank-arm being longer than the crank-arm 10. A pitman 15 is connected to the free end of the arm 14 and has an adjustable connection 16 with the crank-arm 10. The connection 16 is arranged to be placed in any of the openings 1 1, so that the end ofthe pitman secured thereby can be placed at different distances from the axis of rotation of the crankarm and of the drive-shaft 8. By this arrangement it will be clear that if the driveshaft S is rotated `from any suitable source of power the rotating crank l() will cause a backand-forth swinging movement of the pitman 15. The crank 14. being longer than the crank 1() will consequently swing back and forth, and thus the shaft 13 will be rocked.

Secured to the opposite end of the rockshaft I3 to that carrying the crank-arm I4 is a rock-wheel 17, disposed at one side of the iframe and having a series of peripheral grooves IS. (Shown more particularly in Fig.) On opposite sides of this wheel are located oppositely moving reeiprocatory members I9, which in the present embodiment are pump plunger-rods and are vertically disposed, though, as already stated, they may be devices employed for other purposes. The members 19 are shown as extending into well-casings 20, clamped by bars 2l and bolts 22 to one side of the frame. The upper ends of the easings are surrounded by suitable discharge-spouts 23. Doubled cables 24 have their ends adjustably and detachably clamped, as shown at 25, to the upper portion of the wheel 17, said cables passing through openings 26 in the upper portion of the pulley and extending downwardly in the outer peripheral grooves I8. The lower portions of these cables extend on opposite sides of the reciprocatory members 19 and pass about cross-pins 27, that extend through the members 19 and project on opposite sides of the same. Upwardly-extending single eables 2S are adjustably and detachably clamped, as shown at 29, to the lower portion of the wheel and, passing through an opening 30 therein, extend upwardly in the central groove. The upper ends oi' the cables 28 are detachably fastened, as shown at 31,

v to eyes that are carried by the upper ends of IOO lIO

the reciprocatory members. It will be observed that by this arrangement the reciprocatory members move in opposite directionsA upon the movement of the roclcshaft, being elevated by the doubled or looped cables and being moved downwardly by the single cables 28.` Moreover, it will be apparent that either member may be disconnected from the wheel.

In order to oounterbalance either member when operating singly, the following mechanism is preferably employed: A walkingbeam 32 is suitably secured to an intermediate portion of the rock-shaft 13 and has oppositely-extending arms. A longitudinal guideway or track 34, dovetailed in crosssection, is formed upon the upper portion of this walking-beam, and slidably mounted on the track is a counterbalancing device in the form of a weight 35, that is thus movable to positions on opposite sides of. the axis of movement of the shaft 13. A suitable setscrew 36, carried by the counter'weight, serves to hold it in any desired position.

From the above it will be apparent that if the drive-shaft is rotated the rock-shaft will be moved, and because of the connection between the wheel and the reciprocatory members said members will be alternately moved in opposite directions. If these members properly oounterbalance, the weight 35 is of course placed directly over the rock-shaft 13; but if one should be heavier than the other the weight may then be moved in order to assist the lighter in counterbalancing the heavier. If for any reason one of the beams or reciprocatory members is inoperative and it is desired to use the other alone, the beam or member is disconnected by detaching the cables and the weight 35 is arranged on the proper arm of the walking-beam, so that it will counteract or counterbalance the weight of the operating member.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
