J AMES MA'HONEY,

OF MOUNT Amen, anaemia-1i:

Be it known that I, JAMES MAHONEY, a citizen of the United States, residing at Mount Alton, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Hooks for Sucker- 1 Rod Elevators, of which the following is a specification, reference being had therein to the accompanying drawings. I Y

My invention relates to improvements in hooks for sucker-rod elevators, and pertains more particularly to those used in oil-wells. The object of my invention is to provide a hook of this character which is adapted to be hooked into theelevators secured to the upper end of the sucker-rod and so constructed that it is impossible for the same to become unhooked from the elevator by the slacking of the rope or any other cause.

Another object of my invention is to pro vide a more simple, durable,- and eifective hook of this character; g I

In the accompanying drawings, Fi ure 1 is a perspective view of my improved ookasapplied. Fig. 2 is an enlarged side elevation of the hook, showing the weighted tongue closing the same and showing the tongue open in dotted lines. Fig. 3 is an enlarged perspective view of the tongue removed.

Referring now to the drawings, 1 represents the stem of my improved elevatorhook, which,as shown, is ofan elongated form and has an eye swiveled to its upper end, and said eye has secured theret'o'in any manner the elevating rope or cable 3, which,

as understood, passes up over a pulley on the derrick and is wound upon a drum upon the drilling-machine, as is well understood by those skilled in the art. The said shank of the hook at its lower end is provided with the usual hook 4, which is adapted to be hooked into the swiveled eye 5, carried by the upper end of the shank 6 0f the sucker-rod elevator.

The said elevator is constructed of a wellknown form, having-the two downwardlyextending arms 7 and 8, in which is pivotally supported the suoker-rod-supporting member 9, the said member having a slot 10 therein for receiving the sucker-rod 11, the head 12 of said sucker-rod resting upon the member 9, while the finger 13 prevents the member 8 from tilting caused by the weight of the sucker-rod.

The elongated shank 1 of the hook is provided with an obliquely-arranged elongated Speeiiieation of Letters Patent. Application filed Novem r 17, 1905.

Serial No. 287,823.

l opening 14 adjacent its lower end, and in a swingin downwardly below a horizontal line. T e said lower end 18 is also provided with a knob 19, which is adapted to receive the lower edge of the-opening 14, and thus allow the tongue to be swung in an approximately vertical position, sothat the hook may be readily disengaged from the suckerrod elevator. The upper end 20 of said tongue 16 is made round and of a heavy form to overbalance the lower end, and thus normally hold the lower end 18 in engagement with the hook 4.

From the foregoing description it will be seen that should the rope 3 become slackened for any reason whatever the hook would drop and the swiveledeye 5 will engage the lower face of the lower end of the tongue 16, and the hook would be disengaged from the sucker-rod elevator.

Having thus described my invention, what I claim, and'desire to secure by Letters Patent,is 3

1. A hook, comprising a body portion having a long shank, an eye swiveled to the upper end thereof, and the shank having an elongated opening therethrough 'in'which is ratti'aiviaiaiizb; 1966';

prevented from becoming intermediately pivoted the tongue having aweighted upper end. 2. A hook, comprising a body portion having a long shank, an eye swiveled to the upper end thereof, said shank having an elonshank, an eye swiveled to the upper end thereof, said shank having an elongated obliquelyarranged opening therethrough, and an intermediately-pivoted' S- shaped tonguein a line' with the upper end of the hook, and said tongue having its upper end weighted.

4. A hook, comprising a body portion having a long shank, an eye swiveled to the upper end thereof, said shank having an elongated obliquely arranged opening there- In testimony whereof l aflix my signature through, and an intermediately-pivoted S- in presence of two witnesses. shaped tongue within said opening in a line with the upper end of the hook, and said JAMES MAHONEY' 5vtongue having a notch below the pivotal Witnesses:

point to allow the hook to swing downward EDWARD JIFKINs,

in a Vertical line, and a weighted upper end. JAY NORTH.
