wells, pipe must be let down into and withdrawn from the bore, in connection with the drilling operations, and in so handling the pipe, an elevator is first clamped around said pipe underneath one of the collars, connecting the joints thereof and a cable is then attached to the elevator bail, through which the pipe is lifted out of and suspended :into, the bore, said cable being operated usually by means of a drum, not shown, or through other suitable means, provided for the purpose. It is the object of this invention to provide an elevator of simple construction, and which may be read ily applied to and released from the pipe wherein to be handled.v

Another object of the invention resides easily constructed, and easily kept in repair.

. With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification'and illustrated in the accompanying drawings,

ence designate similar parts in each of the figures, the numeral 1, refers to an arcuate member, formed to conform to and fit around the pipe 2, underneath the collar 3' thereof. This member has the oppositely dlsposed eyes 4, 4, secured thereto, to which the bail 5 is attached. To one end of the arcuate member 1, the arm 6 is hinged, and the free end of this arm has the reduced neck 7, and the head 8. When the arm is in closed position, the neck 7 fits into the slot 9, cut

in the other end of the arcuate member 1,

the head 8 resting in the notch 10, of said 7 end, so as to be flush therewith. The head 8 has the transverse notch 11, in the outer end thereof, in which the spring dog 12 is adapted to engage, to' hold the .arm 6 in locked position. Integral with the arm 6, there is a finger 13, curved to conform to the contour of the pipe, and which rests in a correspondingly shaped recess 14, of the member 1, when the elevator is applied to the pipe. As shown in the figures, the elevator is applied to the pipe 2, underneath the collar 3, so that'whe'n it is pulled upwardly, it will engage with said collar and lift the string of pipe. If it now be desired to remove thev elevator, the spring dog 12 maybe manually disengaged, and the member 1 moved laterally, relative to the pipe, causing the pipe to engage with the arm 6, and move it into the position indicated in dotted lines in Fig. 1. In applying the elevator to the pipe, the finger 13 will first engage against the pipe and be swung around thereby and seated in the recess 14,

it will be securely held until again manually released.

' -'What I claim is:

An elevator, includrng an arcuate mem-' ber, conforming in contour to and adapted to be fitted around apipe, a securing arm Fig. 3, is a side elevation taken at right means whereby the arm may be locked in position to hold said arcuate member,

against detachment from 'the'pipe, and an actuating finger carried by said arm, and In testimony whereof I have signed my adapted to be actuated by the pipe, when name to this specification in the presence of the elevator is applied thereto to swing the two su'bscri'bing Witnesses.
