Abstract
A vertical hand stapler has a staple holder, a staple feeder with a housing that receives a staple from the staple holder; a hand operated plunger reciprocating within the staple feeder housing to eject a staple from the staple feeder and permit another staple to enter the feeder; and a deflecting retainer holding a staple in place within the staple feeder housing that is deflected by the plunger to permit a staple to be ejected from the staple feeder.

A vertical hand stapler, comprising:
- (a) a staple holder;
- (b) a staple feeder having a housing;
- (c) the housing further comprising a front wall having an aperture receiving a staple from the staple holder, a pair of side walls, and a rear wall, the front wall, side walls, and rear wall forming a fully-enclosed staple-receiving space;
- (d) a hand-operated plunger reciprocating within the staple feeder housing to eject a staple from the staple feeder and permit another staple to enter the staple feeder;
- and
- (e) a spring comprising material partly cut from the housing along three sides and remaining attached to the housing on a fourth side and being biased against a staple;
- and
- (f) a deflecting retainer attached to the spring and holding a staple in place within the staple feeder housing and being deflected by the plunger to permit a staple to be ejected from the staple feeder;
