  • the base member 10 is of generally rectangular configuration and has a pair of upstanding end walls 16 and 18.
  • the end walls 16 and 18 have V-shaped slots 22 and 24 which act as guides for a line cable or rope 20 as best illustrated in FIG. 2.
  • the handle 26 is Formed integral with the mounting base member 10 is a handle 26.
  • the handle 26 is conventional in nature with an opening through which the fingers may be placed.
  • the jaw members 12 and 14 are each of generally rectangular configuration with the jaw member 12 having a length substantially equal to the distance between the end walls 16 and 18 of the base member 10.
  • the second jaw member 14 has a length somewhat smaller than the distance between the end walls 16 and 18 so that the second jaw member 14 can move into engagement either with the end wall 16 or the end wall 18.
  • the inner faces of the jaw members 12 v and 14 are spaced relative to each other and slope toward each other so as to form a V which, as viewed in FIG. 4, has a separation slightly smaller than the V-slots 22 and 24 provided in the end walls 16 and 18 of the base member.
  • Means is disposed on the inner faces of the jaw members l2 and 14 for gripping the line or cable adapted to be positioned therebetween. More particularly, a series of ridges and grooves 28 are provided on the inner faces of jaw members 12 and 14 and extend the entire length thereof. As best shown in FIG. 6, the grooves slope from the upper lefthand corner of the jaw member 14 to the lower righthand corner thereof at an angle to the base of approximately 45 degrees. The ridges and the grooves on the jaw member 12 are similarly sloped so as to be in alignment with the ridges and grooves on the second jaw member 14.
  • a pair of parallel slots 30 and 32 are provided on the under surfaceof the mounting base 10.
  • the slots 30 and 32 are similar in configuration and each have a head portion and extend parallel to the end walls 16 and 18 for the greater portion of the width of the base member 10 and terminate in a camming curve tail portion 34.
  • Recessed within each of the slots 30 and 32 is a second slot 36 formed by shoulders 38 and 40. The shoulders 38 and 40 extend substantially the full width of the slots 30 and 32 but terminate at the head portion thereof. Accordingly, the heads 42 (only one shown in FIG.
  • cam followers 44 which extend downwardly from the bottom of the jaw member 14, may be inserted in the head portion of the slots 30 and 32 and slipped along the slots toward the tail portion thereof.
