PUMPING-ROD-TURNING DEVICE.

Specification of Letters Patent.

Patented Apr. 3d, 1918.

Application filed May 4, 1917. Serial No. 166,412.

To all whom it may concern Be it known that I, FRANCIS J. OCON- NELL, a citizen of the United States, and a resident of Wellsville, in the county of Allegany and State of New York, have invented certain new and useful Improvements in Pumping Rod Turning Devices, of which the following is a specification.

This invention relates to improvements in devices for turning pump rods adapted particularly for use in oil wells. The object of the invention is to provide a simple device of this character which will be capable of being secured to any of the many forms of pumping apparatus and which will be inexpensive and not likely to get out of order.

The invention consists in the construction and arrangement of parts hereinafter more particularly described and definitely claimed.

In the drawings accompanying and forming part hereof:

Figure 1 is a side elevation of a typical form of well having my invention applied thereto;

Fig. 2 is a top plan View of the same.

Referring now to the details of the drawings by numerals: 1 designates a typical form of well, and 2 the usual pumping rod thereof, this pumping rod, in the einbodiinent shown in the drawings, passing through a cylinder (I by which movement may be given to the pumping rod in a manner now commonly practised. The cylinder has an inlet 5 for the admission of'air or steam, but such cylinders are so common that no further description need be given of the cylinder or the well except to bear in mind that the pumping rod 2 is moved up and down in the operation of pumping.

To the pumping rod 2 is secured a ratchet wheel 8 which is fixed to the pumping rod so that it moves up and down with the pumping rod and can rotate only as the pumping rod is rotated. Immediately above this ratchet wheel 8 I place an arm 10 which is sleeved onto the pumping rod 2 and held in position by a collar 12, it being understood that the arm 10 may be rotated on the pumping rod 2 as an axis. This arm 10 is provided with a. pawl 14 which engages the teeth of the ratchet wheel 8. The free end of the arm 10 is provided with an eye 16 which is sleeved over a slanting support 18. One embodiment of this support is shown in my drawings and as there shown it consists of nothing more than a rod bent so as to be slanting, as shown in Fig. 1, and also to be formed on the arc of a circle of which the pumping rod is the center as illustrated in Fig. 2. The lower ends of this support 18 are dropped into brackets 20 and 21. These brackets may be formed of ordinary pipe flattened out at their lower ends as indicated at 22 and 2a and secured to the top of the cylinder 4,'the ends of the support 18 being secured by set screws 26 and 27 The operation is so simple that it is believed to be evident from the drawings so that it will suflice to say that when the pumping rod 2 is moved vertically up and down in the operation of pumping, the arm 10 slides up and down on the support 18 and as the pumping rod is lowered, said arm 10 will be moved downward with the pumping rod 2 and the ratchet wheel 8 and in moving downward the eye 16 will swing around on the support 18 and therefore cause its pawl 14 to move the ratchet wheel and thereby rotate said ratchet wheel and the pumping rod 2. On the return or upward movement of the pumping rod, the eye 16 will be caused to swing around in the reverse direction as it travels upward on the inclined support 18, thus causing the pawl 14 to slip over the teeth of the ratchet wheel in a manner easily. understood.

I am well aware that it is old to have ratchet wheels attached to pumping rods for the purpose of rotating the same, but I believe that none of the constructions heretofore proposed is as simple and eliective as that shown in the accompanying drawings, and in all those with which I am familiar the pipes cannot be operated except by the movement of a pumping beam or other moving object.

What I claim as my invention is:

1. In a device of the character described, the combination of a pumping rod, a ratchet wheel secured thereto and movable up and down with said pumping rod, a stationary support located adjacent said pumping rod, an arm having one end journaled on said pumping rod and movable up and down therewith, the opposite end of said arm sliding on said support, and a pawl carried by said arm and cooperating with said ratchet wheel whereby as said pumping rod, its ratchet wheel, arm and pawl move up and down with respect to said support, the free end of the arm slides on said support to give rotary movement to said arm and its pawl to rotate the ratchet wheel and pumpsupport located adjacent said pumping rod and having an upwardly inclined part, an

arm having one end journaled on said pumping rod and moving up and down therewith,

' the opposite end of said arm sliding up and down on said upwardly inclined part of 'saidsupport, and a pawl carried by said arm and co-acting with said ratchet wheel, whereby as said pumping rod, ratchet wheel, arm and pawl move up and down with respeet to said support, the free end of the arm slides on said upwardly inclined part of said support to give rotary movement to said arm and its pawl to rotate the ratchet wheel and pumping rod, substantially as described.

3. In a device of the character described, thecombination of apumping rod, a ratchet wheel secured thereto and movable up and down with said pumping rod, a stationary support located adjacent said pumping rod and having an upwardly inclined part formed on an arc of which the pumping rod is the center, an arm having one end journaled on said pumping rod and moving up and down therewith, the opposite end 01 said arm sliding up and down on said upwardly inclined part of said support, and a pawl carried by said arm and co-acting with said ratchet wheel, whereby as said pumping rod, ratchet wheel, arm and pawl move up and down with respect to said support, the free end of the arm slides on said upwardly inclined part of said support to give rotary movement to said arm and its pawl to rotate the ratchet wheel and pumping rod, substantially as described.

4:. In a device of the character described, the combination of a pumping device including a pumping rod, a stationary support carried by said pumping device and having an upwardly inclined part formed on an arc of a circle, a ratchet wheel secured to and movable up and down with said pumping rod, an arm having one end journaled on said pumping rod and movable up and down therewith, the opposite end of said arm sliding on the inclined part of said support, and a pawl carried by said arm and coiiperating with said ratchet wheel whereby as said pumping rod, its ratchet wheel, arm and pawl move up and down on the inclined part of said support, the tree end of the arm slides on said support to give rotary movement to said arm and its pawl to rotate the ratchet wheel and pumping rod, substantially as described.

5. In a device of the character described, the combination of a pumping device including a pumping rod, brackets carried by said pumping device, a stationary support carried by said brackets and having an upwardly inclined part formed on an arc of a circle, a ratchet wheel secured to and movable up and down with said pumping rod, an arm having one end journaled on said pumping rod and movable up and down therewith, the opposite end of said arm sliding on the inclined part of said support, and a pawl carried by said arm and cooperating with said ratchet wheel whereby as said pumping rod, its ratchet wheel, arm and pawl move up and down on the inclined part of said support, the free end of the arm slides on said support to give rotary movement to said arm and its pawl to rotate the ratchet wheel and pumping rod. substantially as described.

In testimony whereof I aiiix my signature in presence of a witness.
