Abstract: An electric powered multiple impact fastener driving tool comprising a handle portion, a main body portion, a guide block, a magazine, and a guide and biasing assembly mounted in the guide block and affixed to the magazine enabling shifting of the magazine within the guide block between an extended fastener starting position and a retracted fastener driven position. The main body portion contains an impact assembly comprising a motor driven cam wheel with a single drop-off, a cam follower roller mounted on a reciprocable hammer, a compression spring surmounting and abutting the hammer, and a fastener driver. For each rotation of the cam wheel, the cam follower roll lifts the hammer, compressing the spring and storing energy therein. At the cam wheel drop-off, the cam follower wheel and hammer drop under the influence of the spring and the hammer impacts the driver which imparts a blow to the fastener. The cam follower wheel does not contact the cam wheel immediately after drop-off.

Abstract: An electronically controlled pneumatic fastener driving tool. The tool is of the type having a body containing a cylinder with a piston/driver assembly therein, a firing valve actuable to introduce high pressure air into the cylinder to cycle the piston/driver assembly, a manual trigger, a safety trip, and an electronic control system. The electronic control system comprises a remote solenoid valve to actuate the firing valve, a microprocessor having inputs from at least the trigger and safety trip and an output to energize the solenoid of the remote valve to cycle the tool, a battery to energize the microprocessor and a rechargeable battery to energize the solenoid of the remote valve. The microprocessor determines the mode of operation of the tool and may be designed to provide two or more modes selectable by a mode selection switch. The input from the trigger is provided with a reed switch closable by the trigger and the input from the safety trip is provided with a reed switch closable by the safety trip.

Abstract: This invention relates to a nail having a head and an elongated shank with two deformed or cleated portions along the axis of the shank to increase the holding properties of the nail, especially when used to secure sheathing material to floor joists, roof trusses, or wall studs. The increased holding property is largely attributed to the second cleated portion having a diameter of about 2-25% larger than the first cleated portion of the shank.

Abstract: A fastener driving tool capable of locating a preformed hole in a first workpiece and driving a nail therethrough and into a second workpiece to attach the first workpiece to the second workpiece. The tool comprises a body having a main portion and a handle portion, a guide body, a drive track in the guide body, a driver axially shiftable in the drive track, a fastener containing magazine, a magazine cover, a manual trigger, and a trigger enabling safety. The magazine cover is supported by the guide body and the handle portion of the tool and contains the magazine. The magazine communicates with the drive track and is supported by a slide captively mounted on the guide body and axially shiftable therealong.

Abstract: An internally threaded fastener assembled from formed laminae can be inexpensively and efficiently produced from a variety of materials in a multi-staged, die-operated, drawing press. Each lamina has an internal bore with less than one full thread form at the helix plane and is designed to be stacked in an aligned, alternating arrangement to provide full thread rotations along the interior of the assembled fastener.

Abstract: A pawl-type assembly for pulling a coiled strip of nails form a canister-type magazine of a nail driving tool and introducing the forwardmost nail of the strip into the drive track of the tool to be driven by the tool driver into a workpiece. The guide body of the tool defines the drive track and has a fixed wall and an openable wall forming there between a passage for the strip of nails from the canister-type magazine to the drive track. The pawl is shiftable by the piston rod of an air cylinder between a rearward position wherein it engages a nail near the forwardmost nail of the strip and a forward position wherein the nearby forwardmost nail of the strip is located in the drive track ready to be driven. The pawl is provided with ledge-like surfaces which, when the pawl is in its forwardmost position, engage the fixed wall of the guide body in such a way as to prevent pawl displacement during the fastener driving portion of the tool cycle.

Abstract: An adhesive device, featuring a target element, absorptive of electromagnetic waves, contiguous with a heat-activatable adhesive material, shaped into an article having a mathematically smooth perimeter, will facilitate a quick, neat, easy and secure assembly of associated component pieces or manufactured articles. Exposing the device to electromagnetic waves will produce heat energy which will activate the adhesive material and result in the bonding of the associated component pieces. This adhesive device is particularly beneficial when used within or between pieces to be assembled that are substantially transparent to electromagnetic waves.

Abstract: A new adjustable collet for stud welding employs a plurality of electrically energizable jaws coordinated to firmly grasp studs of various shapes, sizes and orientations while welding them to a work surface. This adjustable collet will also ensure better contact with the stud and thus reduce the likelihood of arcing and faulty welds. Premature collet wear will also be averted by reducing the amount of sliding contact between the collet and the stud.

Abstract: A canister-type magazine for the class of fastener driving tool which uses a coil of tandemly arranged fasteners. The magazine comprises a substantially cylindrical body having a top, a bottom and a side wall, and is made up of a fixed body part and a movable body part. The fixed body part has a forward end attached to the tool fastener feed mechanism and a rearward end attached to the tool handle. The fixed body part comprises the top and a segment of the side wall of the magazine. The movable body part has forward and rearward ends and comprises the bottom, the fastener coil support surface, and the remainder of the side wall of the magazine. The movable body part is pivotally affixed at its rearward end to a hinge member. The hinge member, in turn, is adjustably mounted in a hinge member support constituting a portion of the rearward end of the fixed body part.

Abstract: A canister-type magazine for a fastener driving tool using a coil of tandemly arranged fasteners. The magazine comprises a substantially cylindrical body having a top, a bottom and side walls. The magazine is openable, providing access to the interior thereof. A cylindrical magazine post extends upwardly from the center of the magazine bottom. A pair of latch members are located in diametric openings in the magazine post near the upper end thereof. The latch members are shiftable between a first position wherein they extend beyond the peripheral surface of the magazine post and a second position wherein they are within the confines of the peripheral surface of the magazine post. The latch members are biased to their first position. A fastener coil supporting platform is provided having a hollow center post with an interior diameter sized to slidingly receive the magazine post. The platform post has at least two pairs of diametric openings in its cylindrical side wall.
