Abstract: A retractable tape measure assembly is disclosed which includes a housing, a coiled tape located in the housing, which tape is adapted to be extended from and retracted into the housing. The coiled tape has a free end with a pull tab secured thereto. A resilient bumper is mounted in the housing in position to contact the pull tab when the tape is retracted. The bumper includes a front surface for contacting the pull tab and a tape support surface behind the front surface extending generally perpendicular thereto. An integral spring is located behind the tape support surface and engages a stop in the housing so that when the tape is retracted the spring is compressed to absorb the stress in the tape. The casing also includes a tape lock mechanism for locking the tape in an extended position. The pull tab also has a rear surface on which a high friction element is placed to help hold the pull tab in position when the tape is extended and engaged with a work piece for measurement.

Abstract: An attachment for a staple gun tacker having a staple driving blade is disclosed which is adapted to be used in driving and setting a rivet of the type having a pin member mounted in a headed rivet shank having an expandable workpiece piercing free end. The attachment includes a housing adapted to be frictionally engaged on the working end of a staple gun tacker and having a bore located to be generally in axial alignment with the driving blade of the staple gun tacker. A hollow flanged bushing is slidably mounted in the housing bore with a spring for biasing the bushing away from the housing to engage the shoulder of the interior of the housing and to permit retraction of the bushing into the housing against the bias of the spring. A pin punch which is axially free floating within its operative range of movement is slidably mounted in the bushing for axial movement therein.

Abstract: A staple gun tacker having a staple driving blade is disclosed which is adapted to be used in driving and setting a rivet of the type having a pin member mounted in a rivet shank having an expandable workpiece piercing free end. The staple gun tacker includes a front cover over the driving mechanism which has a recess or slot formed therein to receive the pin member or top of the rivet and guide it into alignment with the drive blade of the staple gun so that upon operation of the staple gun the driving blade applies a driving force to drive the pin member of the rivet and thus expands the free end of the rivet.

The attachment includes a housing adapted to be frictionally engaged on the working end of a staple gun tacker and having a bore located to be generally in axial alignment with the driving blade of the staple gun tacker. A hollow bushing is mounted in the housing bore and a pin punch is slidably mounted in the bushing for axial movement therein. A spring biases the pin punch towards the driving blade of the staple gun tacker with the bushing and pin being positioned such that the pin punch is impacted by the driving blade of the staple gun tacker when it is operated to apply a driving force thereto, which force is used to drive the pin member of the rivet to expand the free end of the rivet.
