ABSTRACT:

BACKGROUND AND SUMMARY OF THE INVENTION
Cable lifting devices, such as elevators and powered boat lifts, for example, typically comprise a motor, a winder assembly, and a length of cable attached to the winder assembly at one end of the cable. In the case of boat lifts, one end of the cable
1
is typically secured to the spool
2
by means of a cable clamp
4
. The remaining length of cable
1
is transmitted through a pulley system
5
and lifting apparatus (not shown). The cable
1
is first inserted through the end of the drive shaft
2
or spool, as shown in
FIG. 1
, and then through an exit hole
3
drilled through the shaft. A clamp
4
is secured to the cable
1
as shown and acts as a stop when the cable is drawn tightly (in the direction of the arrows
6
), thereby allowing the cable to be wound about the spool. This means of securing a cable to the spool can be time-consuming and labor intensive, however, since the motor often has to be removed prior to installation of the cable.
The present invention is directed to a novel cable-tie off device for use in winder assemblies employing lifting cables, including, but not limited to, winder assemblies used in boat lifts.
