Abstract

1496295 Bumper silenced pneumatic fastener driver SIGNODE CORP 12 March 1976 [12 March 1975] 10007/76 Heading B4C A "silenced" pneumatically operatable fastener driving tool comprises a piston 2 guided in cylinder 1 and having a driver member 12 extending therefrom, the cylinder having an end plate 3 with an opening through which the driver member extends, piston 2 and plate 3 having centrally disposed conical shoulders 4, 7, respectively, and an elastomeric annular bumper supported by shoulder 7 and having upper and lower conical surfaces and a central opening with rounded edges adapted to engage the shoulders, the outer diameter of the bumper when uncompressed being greater than the inner diameter of the cylinder, the bumper being provided with a plurality of axial bores 9 disposed in a circle concentric with the central opening to partially absorb some of the radial expansion of the bumper when it is compressed at the end of the driving stroke. Preferably each shoulder 4, 7 has a cone angle of 60 degrees. The upper piston flange 2a is larger than lower flange 2b so that compressed air in annulus 14 biases the piston to its upper position. The fasteners (nails or staples) are supplied from a magazine (not shown).
