Dual purpose staple gun tacker

A staple gun tacker for driving staples of various leg lengths comprising,

• a staple gun housing having a front staple driving end and a base,
• said base having a staple discharge opening formed therein through which staples to be driven by the staple gun are discharged into a workpiece;
• a staple spacer guide slidably mounted on the staple driving end of said housing and including a free end which extends beyond said staple discharge opening and said base, and
• means for selectively controlling the position of said spacer guide on the housing and the extent to which said free end extends beyond said base, thereby to control the depth of penetration of staples driven by said staple gun into a workpiece;
• said means for selectively controlling the position of said spacer guide on the housing including cooperating means on said spacer guide and on the housing for selectively limiting the position to which the spacer guide can be retracted along the housing relative to said base thereby to control the position of said staple discharge opening relative to the workpiece into which the staple is to be driven;
• said cooperating means comprising a plurality of stop surfaces formed on said housing at predetermined distances from said staple discharge opening and selectively adjustable means on said spacer guide for selectively engaging said stop surfaces;
• said selectively adjustable means comprising a stop plate pivotally mounted on said spacer guide for movement therewith including an abutment surface for selectively engaging one of said stop surfaces in accordance with the position to which said plate is pivoted.
