WILLIAM '1. CLINGER, OF OIL CITY, PENNSYLVANIA.

SUCKER-ROD ELEVATOR.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed February 24, 1914. Serial N 0. 820,703.

To all whom it may concern:

Be it known that I, VVILLIAM T. CLINGER,

drawing sucker-rods from oil wells, such means being usually referred to in the art as sucker-rod elevators.

The object of the device is to provide means of the above described character which will be simple in form, economical of manufacture and efficient in operation.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawlng and the followlng description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the prin ciple of the invention may be a pplicd.

In said annexed drawing :Figure 1 represents a perspective view of a sucker-rod elevator, showing the upper end of a sucker- Fig. 2 represents a view similar to that of Fig. 1, showing the parts in a diiferent position. Fig. 3 represents a partial vertical section of the parts shown in Fig. 1 and showing same in the position in which they are shown in the latter figure. Fig. 41 represents a perspective view showing the parts in still another position.

The illustrated embodiment of my invention comprises a main-member 1 whose upper end is, in the usual manner, provided with a swiveled link 2 to which the elevating rope may be attached. Also as in do vices of similar character, the lower end is provided with two arms 3, 3, the lower end of each of which is provided with a bearing 4 for receiving the trunnions 5 of the slotted plate 6. This plate is similar to those heretofore employed excepting that the slot 7 does not intersect the plate angularly as has heretofore been the custom. This said slot 7 is adapted to engage the upper end of the sucker-rod beneath the threaded sleeve 9, as shown in Fig. 1.

Forming an integral part of the mainmember 1 and located intermediately of the two arms 3, 3, is a downwardly extending guiding-stem 10 whose lower end lies in a horizontal plane above the end of the suckerrod, when the latter is in position in the plate and said plate occupies a horizontal position, as shown. Slidable upon said guiding-stem 10 is a Sleeve 11 of inverted cu rshape form and having an interior reecss 12 adapted to receive the sleeve 9 of the sucker-rod. The upper end of said sleeve is provided with a groove 18 adapted to receive a key or tongue 14 fixedly secured to or integrally formed with the guiding-stem 10, so that said key or tongue may pass through the upper end of the sleeve, as will be readily understood.

In the above described construction, it

will be seen that the sleeve 11 may be turned so as to permit the key to pass through the slot 13, then raised into the position shown in Fig. 3, and then turned so as to bring the slot 13 out of register with said key,

the sleeve being thus permitted to hang in this lifted or raised position. When the parts are in the above described position, the main member 1 may be turned downwardly as shown in Fig. 1, and in this position the plate 6 may be readily caused to engage the upper end of the sucker-rod as shown. When it is desired to pull the sucker-rods, the upper end of the latter is caused to engage the slot, as shown in Fig. 4, mainmember 1, raised into a vertical position as shown in Fig. 1, the sleeve 1]. turned so as to bring the slot 13 into register with the key or tongue let, the sleeve then permitted to drop so as to inclose the sleeve 9 of the sucker-rod, and the sleeve then turned so as to bring the slot 13 out of register with the key or tongue 1 1-. Then the parts are in this position, it will be observed that the upper end of the sucker-rod is prevented from disengaging the plate 6, in which position the rods may be pulled, as will be readily understood. It will also be observed that when the parts are in the above described position, the lower end of the guiding-stem 10 engages the upper end of the sleeve 11, the length of such stem being made sufficient for such purpose, so th t the main-member 1 is maintained in a vertical position without further support, an advantage which will be recognized by those skilled in the art.

When it is desired to disengage the device from the sucker-rod, the order of manipulating the various parts as above described, is reversed.

By means of the above described construction, I obtain a sucker-rod elevator which is so arranged that when the rods are being pulled, all danger of the elevator becoming disengaged from the rods, with the consequent deleterious results, is eliminated, as will be readily understood by those skilled in the art.

Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a sucker-rod elevator, the combination of a main bifurcated member; a member pivotally mounted upon the latter and adapted to detachably engage a sucker-rod; a guiding stem rigidly connected with said main member and projecting between said bifurcations; and a slidable member on said guide-member adapted to engage the end of a sucker-rod while held in said pivotally mounted member.

2. In a sucker-rod elevator, the combination of a main member; a member pivotally mounted upon the bifurcations of the latter and adapted to detachably engage a sucker-rod; a guiding-stem rigidly connected with said main member; a slidable sleeve mounted upon said guiding-stem and adapted to engage the end of a sucker-rod while held in said pivotally mounted memher; and means for locking said sleeve against sliding movement upon said stem.

3. In a sucker-rod elevator, the combination of a main-member; a slotted plate pivotally mounted upon the latter; a downwardly extending guiding-stem rigidly connected with said main-member and terminating in a plane above said plate when the latter is in a horizontal position; a sleeve mounted and slidable upon said stem and formed with a recess adapted to engage the end of a sucker-rod; and means for locking said sleeve in such engaging position.

a. In a sucker-rod elevator, the combina tion of a main-member; a slotted plate pivotally mounted upon the latter; a downwardly extending guiding-stem rigidly connected with said mainanember and provided with a tongue, said stem terminating in a plane above said plate when the latter is in a horizontal position; a sleeve mounted and slidable on said stem and provided with a groove adapted to engage said tongue, said sleeve having its lower surface intersected by a by a recess adapted to engage the end of a,

sucker-rod; said tongue being of a length such that said groove may disengage same when in such engaging position.

6. In a sucker-rod elevator, the combination of a main-member; a slotted plate pivotally mounted upon the latter; a down- 'wardly extending guiding-stem rigidly connected g yith said main-member and provided with a tongue, said stem terminating in a plane above said plate when the latter is in a horizontal position; a sleeve mounted and slidable on said stern and provided with a groove adapted to engage said tongue, said sleeve having its lower surface intersected by a recess adapted to engage the end of a sucker-rod; said tongue being of a length such that said groove may disengage same when in such engaging position; and so as to permit said groove to likewise disengage same when in a raised or disengaging position.

Signed by me this 18th day of February,

WILLIAM T. CLINGER. Attested by- G. F. KRAMER, D. M FINDLING.
