Abstract:
An automatic washer feeder for an automatic nail gun includes a washer storage container (26) for storing a coil (31) of washers (32) and a feeding mechanism (42) for feeding the washers (32) to a position in alignment with nails (50) being driven by the nail gun (16) so that one washer (32) is placed in line with each nail (50) before it is driven.
Abstract:
A tin tag dispensing apparatus for a nailing gun (8) includes a support member (2) having a tin tag dispensing groove (20), a shuttle (6) slidably disposed within the support member, a tube receptacle (32) containing a plurality of stacked tin tags (12), a slide member (40) slidably mounted on the tube receptable, a linkage assembly (50, 56, 62) connecting the slide member with the shuttle, and a mounting plate (72) for connecting the apparatus to the nailing gun. When the gun is lifted, the slide member slides upward along the tube receptacle and causes the shuttle, through the linkage, to engage and displace a single tin tag resting in the tin tag dispensing groove to a nailing station (22) where it is retained until pierced by a fastener (86) discharged from the nail gun.
Abstract:
A fastener feeding mechanism for a power actuated gun (10, 310, 410, 510) having a track (16, 316, 416, 516) for holding a plurality of fasteners (18, 318, 636). Fasteners are biased by a spring (32, 372, 672) down the track towards a holding or latch mechanism (22, 322, 422, 522). The holding or latch mechanism has a retractable latch. The holding or latch mechanism holds a fastener in a predetermined position to be driven into a substrate. A guide (14, 314, 414, 514) attached to a barrel (12, 312, 412, 512) of a power actuated gun guides the barrel permitting the barrel to be advanced for firing and driving the fastener. After firing a bias on the guide causes the barrel to be retracted for the positioning of another fastener to be driven. The present invention greatly facilitates the driving of fasteners having a plate, and permits the driving of fasteners quickly resulting in more efficient and therefore less costly construction.
Abstract:
A roofing gun attachment (2) for dispensing tin tags (38) includes a base (4), a supply chamber (44) mounted on the base (4) which receives a cartridge (60) containing a plurality of stacked planar tin tags (38), a shuttle (40) slidably disposed within the base (4) for individually displacing the tin tags (38) from a feeding station (10) located below the supply chamber (44) to a nailing station (14) where the tin tag (36) is pierced by a nail discharged from a nailing gun, and a pair of cam arms (96, 98) each connected with a slide member (82) for moving the shuttle (40) between the feeding station (10) and the nailing station (14) when the nailing gun is pressed against a nailing surface and lifted therefrom. The supply chamber (44) includes an access door (76) which allows the tin tag cartridge (60) to be easily replaced and further includes a manually-actuated spring-loaded plunger (62) which biases the tin tags (38) toward the feeding station (10).
Abstract:
The invention concerns a slot-shaped magazine (1) containing a sliding pushing member (2) operated by a button (29) for moving staples joined together and for presenting a staple (3) on the hammer. A device elastically retaining the sliding pushing member consists of tabs borne by the pushing member co-operating with click-stop rails (16) provided on the magazine sides (15). The invention is applicable to manual staplers.
