Application filed May 11, 1916.

To all whom it may concern:

-Be it known that I, GEORGE FoeoAN, a citizen of the United States, residing at Pleasantville, in the county Venango and State of Pennsylvania, have invented certain new and useful Improvements in- .a sucker rod elevator having an improved means for preventing the end of the sucker rod from becoming disengaged from the elevator when said rod is connected to the same.

Another object of the invention is to provide a device of this character which is of simple, strong, durable and inexpensive construction, efficient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts which will be hereinafter fully described and claimed.

In the accompanying drawing forming a part of the specification and in which similar reference characters designate like parts throughout the several views: Figure 1 is a front elevation of a sucker rod elevator constructed in accordance with this invention, showing the rotatably mounted plate and slidable sleeve in their respective positions prior to their engagement with the sucker rod; Fig. 2 is a side elevation of the same showing the above mentioned plate and sleeve in their respective operative positions; and Fig. 3 is a horizo tal sectional view taken on the plane of the line 33 of Fig. 2.

Referring more particularly to the drawing, the reference numeral 1 designates the substantially cylindrical shank of a sucker rod elevator constructed in accordance with this invention, and having an eye 2 swlveled between stops 3 in the upper end thereoffor attachment to the usual elevating cable or rope. The lower end of the shank l is provided with a pair of arms 4, the latter forming in efiect a yoke, between Which is Specification of Letters Patent.

Serial No. 96,907.

journaled a plate 5. This plate 5 is provided with a slot 6 which is adapted to receive the upper end of a sucker or well'rod.

Extending laterally outwardly from one side of one of the arms 4; is a lug 7 having an aperture 8 therein, said aperture 8 extending substantially parallel with the shank 1 of the elevator. Slidable on the shank 1 is a sleeve 9 which is formed by coilmg a metal rod 10 around the same as shown. The lower end of this rod 10 is bent laterally to extend substantially longitudinally of the coiled portion thereof to form a stem 11, said stem 11 extending through the aperture 8 in the lug 7. The free end of the stem is disposed adjacent the open end of the slot 6 in the plate 5. To limit the upward movement of the sleeve 9 the shank 1 1s provided with a stop or projection in the form of an enlarged ring portion 12 at a point spaced a short distance above the inner ends of the arms 4. It is to be understood that the shoulders 13 formed at the junctions of the shank 1 and the inner ends of the arms 4 form a second stop for limiting the downward movement of the sleeve 9.

In using the device, the upper end of the sucker rod is engaged with the slot 6 in the plate 5 in the usual manner, it of course being understood that the sleeve 9 is raised to its uppermost position while this engagement is being effected. When this has been done, the sleeve 9 is slid upon the shank 1 to its lowermost position, thereby bringing the free end of the stem 11 adjacent the open end of the slot 6 as hereinbefore described, and preventing the sucker rod from being disengaged from the same, no matter at what angle the shank of the elevator is disposed in raising or lowering the same.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the device will be readily understood without a more extended explanation.

As various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and described other than that set forth in the appended claim.

I claim:

In a sucker rod elevator, the combination with the usual shank having attaching means at one of its ends and a pair of spaced arms at its other end, and a slotted plate 3ournaled between said arms; of an apertured lug formed on one side of one of said arms, a rod coiled around said shank and slidable thereon and forming a sleeve, one end of said rod being bent laterally to extend substantially longitudinally of the coiled portion thereof to form a stern, said stern extending through the aperture in said 10 lug and having its free end disposed adjacent the open end of the slot in said plate, and stops on said shank for limiting the movement of said sleeve.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

GEORGE FOGGAN. Witnesses:

JOHN DAoK, GUY SKINNER.
