Boat lift cable lock apparatus
First Claim
1. In a boat lift, the improvement comprising:
- means for driving a cable in a longitudinally vertical manner;
means defining a boat supporting platform;
means for supporting said means for driving above said platform;
a cable operably interconnecting said means for driving and said platform; and
a locking apparatus for releasably and longitudinally adjustably fastening said cable to one of said platform and said means for supporting;
said locking apparatus including a bracket rigidly secured to one of said platform and said means for supporting and including a tapered channel, which has a wide portion and a narrow portion, and a correspondingly tapered wedge element that is slidably mounted within said channel;
said cable extending through said channel between said wedge element and said bracket;
said wedge element being urged selectively toward said narrow portion of said channel to frictionally lock said cable between said wedge element and said bracket and toward said wide portion of said channel to unlock said cable and permit said cable to slide longitudinally through said channel between said wedge element and said bracket whereby the length of said cable may be adjusted.

Abstract
A boat lift locking apparatus is disclosed for releasably fastening a cable to a structural component of a boat lift. The apparatus includes a bracket secured to the structural component and having a channel, which has a relatively wide portion and a relatively narrow portion. A locking element is slidably mounted in the channel. The cable extends through the channel between the locking element and the bracket. The locking element is urged selectively toward the narrow portion of the channel to frictionally lock the cable between the locking element and the bracket and toward the wide portion of the channel to unlock the cable and permit the cable to slide longitudinally through the channel between the locking element and the bracket.
