My patent application-relates to clamping devices for use-upon cables, cable ways, guy lines; and infany and all places where it is found desirable to placea clamp to which blocks, tackle, guy lines, and the like may be attached or to be used as a splicing I One of the objects of my deviceis to provide a clamping devicethatmay be placed on the linewith the line in place without the removal of the line orthe' loosening of one end of the line. V

a A further object of my device resides in applied to the cable; or line; a piece at a time and "the clamping mechanism be applied without theremoval 'of the line, or the loosening of one end of the lin'e.

A further object of my device resides in a structure adapted for being attached to a cable way, guy'line or sky line in place and to which may be attached any desired block or tackle, 'qui'ckly and Without undue loss oftime.

. Referring to the mechanism illustrated in Figs. 1, 2, 3 and 4, as the'same applies to single ended clamps in'w-h-ich a split body member 1 and 2, is formed of independent units having a central section '3, hingedly secured to one of the side bodyv members by any suitable fastening means. Each ofthe side body members 1 and 2. form substantially a vhalfcylinder 4'and 5, with the hinged member 3, having substantially. a half cylinder '6 and 7 disposedat oppositely disposed sides, so that if a splice is to be ffiormed,-as illustrated in Fig. 1, the main line 8 maybe passed through one of the sides .ofthe clamp and the return end 9 may be passed through the oppositely-disposed side of the clamp to form an eye 10 Within lthe-bi ht. 'Bodymembers 1 and .2 are threaded on their outer periphery to which the male end 37 may be threaded. To prevent 6 the slippageyof the central. section "longi- 3 tudina'zlly of the line, a lug 12 outwardly extendsfrom the side of the central section.

The lug being adapted to engage within the receiving recess 13, disposed in one of the side sections. The side body elements 1 and 2 are hingedly secured together by a hinged 7 link 14 that is disposed therebetween, and

'the same is held in :placeby journal pins 15 and 16. :VVhere the double endedclamp is 'to be diormed, thesame may be made as illustrated in Figs. v5 and 6,.wherein the central side wall body members 17 and 18 are hingedlv secured together and wherein male threaded sections 37 are adapted to threaded engagement with the oppositely disposed ends of the side sections 17 and 18. The central section 21 being adapted to engage oppositely disposed sides OfpthG cables 22 and 23 being disposed therebetween.

A modified form of the clamp may be made, as illustrated in Figs. 7 and '8 where-. -in'the central side wall sections 24 and 25- have uniformlytapering, oppositely disposed ends, to form .aclampingd'evice for a single cable to be passed therebetween. Male clamping collars 26 ;and 27 are adapted to being driven upon oppositely disposed ends 7 ofthe clamp and when a suflicient pressure has been developed between :the side wall members 24 and25 and the cable '28 to be passed therebetween the same are held in relatively fixed position relative to the . side wall members 24 and 25 by the locking device 29. 'A slot 30 is longitudinally disposed on the outer surface of eachof the collars 26 and 27 5 with lockingv notches 31 ment within the locking notches so that when the collars are driven home on the clamping device it is maintained in position through thelockinghook engaging the looking notches. I

.lVhere the clamping device is to be used on logging operations, or on ships tackle, the device may be made ,as illustrated" in Figs. 9,10, 11., 12 and 13, and wherein the central sections 34 and ,35' are adaptedzto -:coact with each other and wherein the side wall member .34 has a central ri'b 36. down- A wardly extending from \the horizontal central line of the body portion 34. After'the bodyvmember-34 is placed upon the-line, as illustrated in Fig. 10 the adjacent section is then put in'iplace within the yoke 36. The A female engaging .endsect-ions 37 and 38 which are made split, as illustratedi-n Fig. 13, are then placed about the threaded end sections of the central members, whenp'laced *thereupon, the locking pins 39 are then in-3 sorted-- within the free end section of the supporting block 43 is then raised :to positiongthe same being hingedly supported to the yoke by a journalpin 44 after which the-supportingblock is maintained in posi- .tion through the locking pin 45. The supporting block 43 may have any suitable supporting means associated therewith as a ring 7 '46 into which .ayoke 47 is-made to engage for supporting any suitable tackle gear as .a

' block 48.

. While the form of :mechanism .herein shown :and described is admirably -adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to con- ;fine the invention to theforms oi embodiments herein shownyand described, as it is susceptible ofv embodiment in various other 3120 forms, all coming within the scopeof the claims which follow:

WhatIclaimis: I

11. Ina device of the class described, the combination of male .and female coin-S ing i clamping elements, the male element comprising two sections hingedlysecuredwith each other beingthreaded their outer periphcry, ;a separator hingedly disposed longitudinally therebetween having a concaved no surface disposed on its oppositely disposed sides and male elements having means hingedly disposed thereon for permitting their placement about the -male element Without disturbing the cable.

2. In a device of the class described, the combination of male and female clamping elements in threaded relationship "with each s other, the male element comprising a plurality of semi-cylindrical"units hingedly connected with each other and a separator bin edly disposed therebetweenadapted for maliing two complete cylinders when in closed position, threads disposed on their outer periphery, meansdisposed within two units for the preventing of longitudinal slippage of the separator section when clamped on a line, the male elements compris ng a plurality of units hingedly connected with each other, threads disposed on their inner walls, and means for locking the said units when the male sections are placed in position for threading together the male and face each having a hinged opening, and

means for locking these hinged openings after placement of the female sections about the male section.
