The locking member 3|] is preferably of a metal having suitable exibility and tensile strength to provide a spring action, see the dot and dash lines of Figure 4. The member has an extending latch portion or element 3| adjacent one end and an upwardly extending guideor slideway portion 32 adjacent the other end, see also Figure '7. The guide element or member portion 32 is provided with projecting flange or keyway portions 34 that are adapted to cooperatively eny gage slotted keyway or lengthwise extending guide portions 34a within the body for bore of member portion I6. The keyways Sila extend. lengthwise from the top of and along the smaller bore I3 of the body portion I6. The inner: face 35 or guides 33a extending lengthwise or down.

facet of: ledge portion a wardly from a front along bore I3. Y

The locking member 30 is mounted in slots I9 and 23 by inserting its key portions 34 into slotted keyways 34a at the end of lthe body portion It:

and its key portions 33 into the slotted keyways 33a at the ledge 35a and-sliding the member 33 downwardly into and along the laterally open slots I9 and 2|! to at least substantially close them olf and force the latch portion 3| over the latch face 22. l

The latch portion 3| is thus flexed outwardly as shown in Figure 4 and snaps into a latching position shown in Figure 2. This locks the member 30 in such a way as lto securely hold it in position within or over the slots I9 Vand 2B. The latch portion 3| of the member 30 is provided, see particularly Figure 4, with step-like or laterally oifset portions a and c connected by a vertical face portion b which are adapted to be tension-forced into a clamping relationship over and into abutment with extending ledge portions 2| and 23 and inclined and connecting face portion 22 of the body I0. That is, when the latch-l ing device 30 has been slid down to its lower position, the portion 3| which extends beyond the slots will be forced over the extending portions 2|, 22 and 23 of the body member I0 to positively lock it in position thereover. Portion 3| of the latch 3E! is deflected in a spring-like manner outwardly as the member 3D is forced downwardly. Thus, tension of the member 30- aids in forcing the portion 3| against and over engaging portions of the body member I0.- The locking member 30 can be quickly removed by` inserting a pry bar into opening f between an inclined face e of the latch portion 3| and an inclined face 24 Vof the body IU in such a way as to engage a bight 25 cut in the face 24. Thus,- the pry bar can be forced against the-portion 3| to spring -it outwardly and permit it to be raised lengthwise out of the keyways 33a and 34a and then laterally out of the slots I9 and 20. s

It will be noted that a longitudinal flange of the portion 32 of the locking member completely closes the slot 20 when the member is in its mounted position in such a` manner that compression force such as exerted by a grapple engaging the inwardly oisetextending portion I6, cannot collapse it irran inward direction'.-

It will be apparent that one of the pair of spaced guideway latch portions 33 and 33a or 34 and 34a can be eliminated if desired.

The device can be made, if desired, in a forge shop by utilizing a drop hammer.

In utilizing the invention, one or more tool strings may be fitted with body members such as I0 which in turn may be connected to bail or sand pumps or other well tool apparatus by threaded portions'- Ita. A cable assembly such as vII and I8' may then be inserted and removed as desired from a body member such as I0. In

mounting the locking member 30, suicient pressure is applied to its upper end to force its latch portion 3| downwardly over the ledge 22 until it engages and springs over the projecting step portions 2| and l23.

n The tool string is then in an operating condition and may be lowered into the well bore to perform its intended work. After the work of a particular tool has been accomplished-and'another tool or device is to be employed, the string is raised out of the drill hole and the locking member 30 removed as above indicated to permit the substitution of another tool without removing the previous tool from the body II).v That is, a number of tools may be attached to va number of body portion members'I, ready for quick use as needed. By utilizing? the device shown, a cable Il and I8 may be quickly and easily mounted in body portions ID of a tool string as desired. Y f

'Although for purposes of illustration, I have shown a particular embodiment of my invention,

it will be apparent that other embodiments and `that 'various modifications, additions and substitutions may be 'effected on the embodiment shown without departing from the spirit and scope of the invention as indicated by the appended claim.

What I claim is as follows:

A rope socket device for wells which comprises, a barrel member having a cable-receiving upper part and a cable-socket-receiving main 1cody part terminating in a lower part for attaching it to a tool or well string, said cable-receiving part having a threaded male-upper-end of smaller diameter than the remainder of said cable-receiving part .which latter is ofsubstantially the same diameter as said main body part and is connected to said main body part, said cable-receiving part having ,a bore extending longitudinally therealong from-itsupper end and extending laterally through a side wall portion of said cablereceiving part, said main body part having a longitudinally extending -bore entrant to and of larger Adiameterthan the bore of said cable-receiving part, an upper portion of the larger bore of said main body .part extending laterally through the sidewall f said main body part and fromthe corresponding lateral extension of the bore of said cable-receiving part and having a length at least equivalent to the length of a cablesocket to be introduced and removed therethrough, said -main body part having a pair of stepped-ledge portions sloped outwardly from a lower end of the lateral extension of the larger bore -of said main body part, a longitudinal guideway entrant from the upper end of and extending along the wal1 of said cable-receiving upper part'whch is adjacent tothe lateral extension of thebore thereof, a second longitudinal guideway entrant from an upper face of a shoulder formed between the smaller diameter upper end and'the remainder of said cable-receiving part and extending along the Wall of the remainder of said cable-receiving part which is adjacent to the lateral extension of the bore of said part; a locking member having a length greater than the combined lengths of the said bore extensions of said body member, said locku ing member having an inwardly oiiset upper part of a length and width substantially corresponding to the length and width of the lateral extension of the bore of said cable-receiving part, said oiset upper part of said locking mem-- ber having guideway portions constructed and arranged to cooperatively engage and slide along the said first-mentioned longitudinal guideway of said cable-receiving upper part and to enter said guideway from the upper end of said part, said locking member having a lower part connected to its inwardly offset upper part and being outwardly offset with respect to said upper part thereof, said lower part of said locking member having guideway portions constructed and arranged to cooperatively engage and slide along said secondmentioned longitudinal guideway of said barrel REFERENCES CITED The following references are of record in the file of this patent:
