MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 589,614, dated September *7, 1897.

Application filed February 28, 1896. Serial No. 581,129. (No model.)

To all whom it may concern.-

Be it known that we, SIDNEY M. POLSON, Janus T. POLSON, and J onn A. POLSON, of Laclede, in the county of Linn and State of Missouri, have inventeda new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.

lhe object of the invention is to provide a new and improved mechanical movement designed for use in well-drilling and other machinery and arranged to permit a long drop of the working tool and requiring but aco1nparatively small amount of power for again lifting the tool to a dropping position.

The invention consists of a rope-carrying arm, a crank-disk having a Wrist-pin on which said arm is fulcrumed, and a second wristpin adapted to form a rest for said arm.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a front elevation of the same, and Fig. 3 is a like View of the same with parts in a different position.

The driven shaft A, journaled in suitable hearings on a frame 13, is provided with a crank-disk C, carrying a wrist-pin D, on which is pivoted an arm E, carrying near its outer end a sheave or pulley F, of any approved construction. Under this pulley F passes a rope G, adapted to be fastened at one end,

G, to a suitable fixed part of the framework,

the other end of-the rope extending upwardly to pass over a sheave or pulley I-I, held in the standards 13 of the frame B. wart'lly-extending run G of this rope carries the drilling-tool or weight to be dropped.

On the crank disk C is arranged a second wrist-pin I, preferably located diametrically opposite the wrist-pin D, so as to form a rest for one side of the arm E when the crank-disk O is turned, as plainly illustrated in Fig. 2. Now it will be seen that when the drillingtool is in a lowermost position then the parts The down-.

of the mechanical movement are in the position illustrated in Fig. 3, and in order to'raise the drilling-tool to a dropping position the crank-disk O is turned in the direction of the arrow a, whereby the Wrist-pin I, after a halfrevolution of the disk, is brought into an uppermost position to form a rest for one side of the free end of the arm E, as indicated in Fig. 2, so that during the second half-revolution the Wrist-pin I carries the arm E around on the face of the disk C. In doing so the tool or Weight is lifted a second time, and when the arm E finally passes a central position the arm E will swing upward in the direction of the arrow a to cause a long drop of the drilling-tool or weight. The above-described operation is then again repeated.

\Vhen it is desired to feed the tool orweight,

the end G of the rope G is loosened and let out a suitable distance, corresponding to the desired feed.

. It is understood that the device is very simple in construction, requires but little power,

and permits of giving a long and forcible drop to the tool or weight on the downward run G l of the rope G.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of a continuously-rotating crank-head, an arm pivoted to the face of said crank-head at one side of the center, and a stop fixed to the face of the said crank-head and adapted to engage the said arm at a predetermined point in each revolution, substantially as described.

2. The combination of a contin uously-rotating crank-head, an arm pivoted on the crankhead face at one side of the center, anda stop fixed to the crank-head face at or near the opposite side and adapted to engage the free end of said arm once in each revolution and carry it around until it passes over its pivotal center and drops forward, producing an alternate liftand-drop motion while the crank-head is being rotated continuously in one direction, substantially as described.

3. In combination with a cranlchead, and means for rotating it continuously, an arm pivotally connected to said crank-head at one IOCI side of the center, a sheave pivoted on the said arm, and a stop adapted to engage the free end of the said arm at a predetermined point in each revolution and to carry it around until it passes over its pivoted center and drops forward, substantially as and for the purpose set forth.

4. A mechanical movement, comprising a rope-carrying arm, a crank-disk having a Wrist-pin on which said arm is fnlcrnmed,

V and a second wrist-pin adapted to form a rest for said arm, substantially as shown and described,

5. A mechanical movement, comprising a crank-disk having two wrist-pins located 0pposite one another, an arm fulcrumed on one of said wrist-pins and adapted to rest on the other wrist-pin, and a rope-receiving sheave of said arm, a second sheave suspended above said disk, and a rope adapted for carrying a tool and passing over said sheaves, as set forth.
