Specification formingpart of Letters Patent No. 175,564, dated-April 4, 1876; Reissue No. 8,262, dated May 28, 1878; application filed August 18, 1877. I

To all whom it may concern:

Be it known that JOHN W. HULL, of Eagundus,-in the county of Forest and State of Pennsylvania, did, in his lifetime, invent a new and useful. Improvement in the Method of Operating Pumps for Artesian Wells, ldmes, &c:,;of which the following is a. descrip- Thisfinvention is a method of operating pumps located near each other, asinoil-wells, where the power which operates one pump may, by suitable connections, be transmitted to others, so that but one engine or other ber of pumps.

Inthe accompanying drawing, Figure 1 represents one way of applying the inventors method.

In said Fig. 1, A represents the piston-rod of a pump. Such a piston-rod is generally called in the, oil regions (for use, in which this invention is particularlyadapted) the polished rod. To this rod a reciprocating perpendicular motion is given by any suitable means. To the polished rod A the rack B isclamped by screws at a and b. The rack B is thus adjustable at any convenient part of the polished rod A. I

N ear the well is firmly fastened the post H. A similar post (not shown in the drawing, as it is obscured by the post H,-) is fixed at a proper distance. On these posts are boxes, as shown at G, forthe reception of the journal F. Attached to the journal E is the pinion G, provided with two arms, one of which is shown at D. I

Fastened to the posts is the frame K, which supports the pulley L. The function of this pulley is to guide the rack B, and keep its cogs engaged with the cogs'of the pinion C. It revolves as the rack moves, thus diminishing the friction.

It is evident that as the rod A is moved up anddown an oscillating motion will be given to the arm D and to the lower arm. Near the ends of said arm D, and of the other arm are attached to the studs M, or in any other and E. At the points of connection provision is made for the necessary adjusting movement. These rods E and E are then carried to and connected with the arms of a similar rack and pinion, B O.

The important element of this invention, which distinguishes it in the greatest manner =ron1 all other methods of simultaneously pumping two. or more wells, isthe double cords E E, so that the-polished rod of the second or subsequent wells are not only raised, but are also depressed, by .a positive motion.

lieu thepiston A of the first pump is put in'metion, the motion is communicated, through the rack B and pinion O and rods E and E, to the second rack B and pinion G and to the piston A, and the action is reciprocal, so that when A is being drawn up A is being drawn down, and vice versa. They thus balance each other; but if it should be desired to have both pumps make the upward and downward strokes together, the cords E and E may be crossed, as shown by the dotted lines. In this method the cords E and B should be stretched quite tightly from arm to arm, or otherwise the full motion of one arm will notbe communicated to the other.

The tension is given to the cords by screws and nuts, as shown at I and J and I and J.-

These screws and their nuts may be made as long as required for the purpose.

More than two pumps may be attached together by extending the cords E and E past the arms D and D, as shown by the dottedlines, and attaching them to other similar racks and pinions, (crossing the cords when needed to secure a balance,) and thus communicating the power to as many pumps as may be desired, any change of direction being made by rocker-shafts or pulleys. Instead of communicating the power first to the pinion O by the rack B, a horizontal wl1eel,as shown in Fig. 2, may be used. To the wheel N an oscillating motion is communicated by any power. The wheel may be toothed, and have around its circumference any desired number of pinions, with arms, operating as before described.

What is claimed as new, and desired to be secured by Letters Patent, is-

1 Double wires, rods, or cablesconnected to arms attached to segment-gears meshing with racks having an alternate reciprocating motion, for the purpose of operating two or more pumps by one motive power.

2. In an arrangement for operating several pumps from one motive power by means of 7 segment-gears acting upon reciprocating racks attached to pump-rods, an adjustable clamp 'upon the piston-rod, substantially as shown and described.

3. A rack and pinion attached to a piston, connected by cords with another rack and pinion attached to another piston, by which the motion of the first piston is communicated to the other piston, substantially as shown and described, and for the purpose set forth.

4. The combination of the polished rods A and A, racks B and B, piuions G and C, clamps a b and a b, and cords or cables E and E, substantially as shown, and for the purpose specified.
