ABSTRACT:
The present invention provides a means for applying a substantially constant force to move clips in queue within an applicator, as well as means for more effectively dispensing the endmost clip from a column of abrasive clips within an applicator. The constant force means generally comprises a constant force spring which is movably secured at both ends within a chamber in the applicator such that the pressure exerted between the ends of the constant force spring forces the clips in queue toward the jaws of the applicator. The dispensing means generally comprises a spring that applies sufficient pressure against the endmost clip in a column of abrasive clips to dispense the endmost clip from the column while preventing the next endmost clip from being dispensed until after the endmost clip has been forced into the jaws of the applicator and applied.
