A hand-held staple driving tool is provided for driving staples near to obstructions, such as walls. The tool has a solenoid, a olenoid plunger and a staple driving knife which is mounted generally parallel to the axis of the solenoid, but outboard of it near the front of the housing. The staple driving knife is connected to the solenoid plunger by means of an overhung transverse drive beam which is connected at its forward end to the upper part of the knife and at its rearward end to the top of the plunger. The tool further has a siamese twin housing which has a live hinge at its front end. The tool has an extended staple driving chute to permit driving staples into small recesses. The tool further has a combination mounting and grounding device using only a single screw. A staple driving tool is also provided which has a staple driving knife centrally aligned with the solenoid plunger and connected to it by means of arcuate wings on the upper end of the knife press fitted around an attachment rod at the bottom end of the plunger.

A hand-held, electrically-driven staple driving tool comprising: (a) a housing; (b) an electromagnetic solenoid coil mounted to said housing, said coil having a central hole; (c) means for energizing said solenoid coil; (d) a magnetizable primary drive plunger centrally aligned with the hole of said solenoid coil, said primary drive plunger being free to move in a linear direction from an extended position to a retracted position into said central hole of said solenoid coil upon energization of said solenoid coil; (e) means for urging said primary drive plunger from said retracted position to said extended position; (f) a mainframe assembly mounted to said housing; (g) a staple magazine; (h) means for mounting said staple magazine to said mainframe assembly in a predetermined position; (i) a generally straight staple driving knife positioned outboard of said solenoid coil and oriented generally parallel to the linear direction of motion of said primary drive plunger and non-axially aligned with said primary drive plunger; and (j) a drive beam, said drive beam being positioned above and oriented transverse to the direction of motion of said primary drive plunger and having a first end and a second end, said second end being operatively connected to the upper end of said primary drive plunger and said first end being operatively connected near the upper end of said staple driving knife so that motion of said primary drive plunger in a generally linear direction between said extended position and said retracted position causes an approximately simultaneous and equal motion of said staple driving knife in a direction generally parallel to the direction of motion of said primary drive plunger; and (k) a guide shaft fixedly mounted to the housing and positioned between said primary drive plunger and said staple driving knife, said guide shaft being slidably received into a hole in said drive beam between said primary drive plunger and said staple driving knife to guide said drive beam in an up and down path.
