摘要:
A fastener driving device (10) includes a housing containing a chamber (20) for storing compressed air a cylinder structure (34) disposed within the housing, a piston (26) movably disposed within the cylinder, a driver (33) connected to the piston, a main valve (38) cooperable with the cylinder structure and movable between an open position and a closed position. The main valve (38) in its open position allows air to move the piston through a drive stroke. The fastener driving device also includes a trigger valve (36) operable between first and second positions. The trigger valve in its first position communicates air pressure from the chamber (20) to the main valve (38) through a signal passageway (43) so as to retain the main valve in a closed position. The trigger valve in its second position allows the air to be exhausted to atmosphere through the signal passageway (43) to permit the main valve to open. The cylinder (34) and the signal passageway (43) comprise an integrally molded structure.

A fastener driving device (10) includes a nose assembly (22) carried by a housing (12) that has a reservoir (14). The nose assembly (22) has a fastener drive track (24). At least a portion of the fastener drive track (24) is defined by a movable portion (28) of the nose assembly (22). A fastener driver (42) is movably mounted in the housing (12) and configured to enter the drive track (24) and drive successive leading fasteners (32) into a workpiece (WP). A head valve (58) is constructed and arranged to be actuated so as to allow the pressurized gas to move the fastener driver (42) through an operating cycle. An actuator (64) is constructed and arranged to actuate the head valve (58). The actuator (64) includes a trigger valve (66) constructed and arranged to allow passage of the pressurized gas from the reservoir (14) to a chamber (70) above the head valve (58), and a contact valve (68) operatively connected to the movable portion (28) of the nose assembly (22).

A pallet having wooden boards (12,18,24) secured together by nails (32) which achieve approved operating characteristics. The nails (32) are embodied in a package secured together by a pair of parallel wires (34) welded to the shanks (36). Each nail has a shank diameter between 0.198 cm and 0.216 cm (.078 in. and .085 in.), each nail is manufactured from steel wire and has a length between 3.8 cm and 5.8 cm (1.50 in. and 2.25 in.). The ratio of the head diameter to the shank diameter of each nail is between 2.70 and 3.37.

A fastener-driving tool (10) includes an integrated function member (50) that performs at least two of the following three functions: a check pawl function, a last fastener-retaining function, and a dry fire lock-out function. In the disclosed embodiment, the integrated function member is provided as a lever-type structure that constitutes part of the access door assembly by means of which access is gained to the fastener drive track (31) along which fasteners (e.g., roofing nails) are fed to the driving portion of the tool. Also disclosed is an improved method of retaining the last nail in the drive track by a lateral head gripping action and a tool for performing the method.

摘要:
The present invention provides a nail (10) suitable for sheathing which provides an enhanced resistance to failure. The nail (10) includes an enlarged head (20) as well as a shank (24) having surface deformations (28). Sheathing panels (40) are secured to a framing structure (42) through the use of the nail (10). The enlarged head (20) provides a first clamping surface that is seated against an exterior surface of the sheathing panel (40). The framing structure within which the shank is secured is a second clamping surface. Through the provision of an enlarged head and a shank having surface deformations, the ability of the nail to maintain the securement of the sheathing panel to the framing structure element is enhanced. A plurality of the nails are disposed within a package (100) suitable for use with mechanical drivers.

A fastener driving device (10) comprising a magazine assembly (54) including a rearward nosepiece portion (58) cooperable with a fixed forward nosepiece portion (60) to define a fastener guiding portion of a fastener drive track (30) of the device. A spring biased releasable latch assembly (56) is manually movable between 1. a normal operating position resiliently biasing the magazine assembly into the normal operating position thereof enabling the rearward nosepiece portion of said magazine assembly in cooperating relation with the forward nosepiece portion to be yieldingly moved therefrom, 2. an intermediate position wherein the magazine assembly is resilient retained against movement beyond the intermediate position thereof to enable jammed fasteners to be removed from between the spaced apart rearward and forward nosepiece portions and 3. a separating position enabling the magazine assembly to be freely moved beyond the intermediate position into separated relation with respect to the frame structure.

摘要:
The exterior surface (104) has a shape facilitating manual rotational movement of the adjusting member (94) by a manual rolling action thereof. A yieldable holding member (106) is mounted on the another structure (90) for linear movement toward and away from the exterior surface of the adjusting member (94) while being restrained against axial movement with respect thereto. The yieldable holding member (106) is spring biased to continuously engage the exterior surface (104) of the adjusting member (94). The yieldable holding member (106) is constructed and arranged with respect to the exterior surface (104) configuration of the adjusting member (94) to continuously yieldably hold the adjusting member (94) in a selected one of a series of rotational positions against free rotational movement in either direction while allowing manual rotational movements against the spring (112) bias of the yieldable member (106) in either direction with generally equal manual effort.
