Abstract
A stapler is disclosed having an anvil moveable from a clinching to a non-clinching position. In either selected position cooperating stops are provided to retain the anvil in position. To move from one position to the other a pivot arrangement is provided for the anvil support arm to pivot the same to the frame of the stapler. To engage and disengage the stops the anvil support arm is moved axially of the pivot.
Claims6
In a stapler having a frame, an anvil for clinching staples, an anvil support arm, and pivot means mounting said support arm on said frame for rotational movement about the axis of said pivot means to and between a first clinching position and a second non-clinching position, the improvement comprising:
- (a) first and second positioning stops on said frame,
- (b) first and second cooperating stops on said arm for cooperation respectively with said first and second positioning stops,
- (c) said first cooperating stop engaging said first positioning stop in said first position of said anvil to maintain said arm and said anvil in said first clinching position,
- (d) said second cooperating stop engaging said second positioning stop to maintain said arm and said anvil in said second non-clinching position, and
- (e) said pivot means mounting said anvil support arm to said frame also providing for relative movement axially of said pivot means of said frame and said anvil support arm to engage and disengage said cooperating stop with said positioning stop thus permitting movement of said arm to and between said first and second positions.
