초록 ▼

A tool for driving fasteners includes a casing defining a nose portion and a handle portion within which is a reservoir for pressurized fluid. A driver is mounted in the nose portion that is reciprocated by a piston attached thereto and an assembly for returning the piston to a static position after a driving stroke is also included. The return assembly includes a chamber in fluid communication through an inlet with pressurized air and with an outlet that is in communication with a location beneath the return piston. A diaphragm is mounted within the chamber and is biased by a shoe and spring into sealing engagement with the inlet and the outlet. Another metered inlet is also included in the chamber that is in fluid communication with the source of pressurized fluid and controls the sealing action of the diaphragm. The chamber for the return assembly is also in fluid communication with a second chamber within which is mounted a differential area piston. The piston includes a feed pawl for feeding fasteners to the driver from a magazine. The magazine is defined by two identical portions that are reversed upon assembly. Fasteners for the tool are fed from the magazine to the driver on a tape and each fastener is held by at least one tab. To prevent the fasteners from dislodging from the tape, the tool includes a shoe biased into engagement with the fastener and the tab.

대표청구항 ▼

A fastener magazine assembly for a fastener driving tool, comprising first and second identical housing portions, said first and second housing portions defining a discharge opening for fasteners to be mounted at a predetermined position on said fastener driving tool, identical attachment portions on each of said first and second housing portions, and means on said fastener driving tool for detachably securing said magazine to said fastener driving tool in at least two different positions wherein said discharge opening is located at said predetermined position in each of said two different positions. A fastener driving tool including a casing defining a pressurized fluid reservoir and a nose portion, and a fastener driver mounted in said nose portion, the improvement comprising a fastener feeding assembly including a piston with first and second portions, said first and second portions being of differential areas with said first portion of said piston being of a greater cross-sectional area than said second portion, wherein said first and second portions are of different geometrical configurations, and first and second feed pawls secured to said piston.
