Abstract: A powered fastener driver comprising a housing, a nosepiece coupled to the housing and extending therefrom, a driver blade movable within the nosepiece between a ready position and a driven position, and a pusher mechanism coupled to the nosepiece for individually transferring collated fasteners in a canister magazine to a driver channel in the nosepiece in which the driver blade is movable. The pusher mechanism includes a feeder arm and a linkage positioned between the feeder arm and the driver blade. The feeder arm is engageable with individual fasteners in the nosepiece for sequentially pushing each of the fasteners into the driver channel in response to movement of the feeder arm toward the driver channel. The linkage is movable to advance the feeder arm toward the driver channel in response to contact with the driver blade as the driver blade moves from the driven position toward the ready position.

Abstract: A feeding pin 146 is downwards inserted into an insertion hole h formed in a direction in which the hoop T is fed so that the feeding pin 146 is moved in the feeding direction. The feeding pin 146 is completely caught by the hoop T to restrain the hoop T in the feeding direction. Thus, overrunning of the hoop T can completely be prevented. Thus, the hoop T can be stopped at a predetermined position. Moreover, cutting of the hoop T and separation of the terminal by cutting can accurately be performed. A hoop holding pin 151 is downwards inserted into the insertion hole h formed at a position different from a position at which the feeding pin 146 is inserted prior to insertion and removal of the feeding pin 146. Thus, further accurate feeding of the hoop T can be performed and, therefore, accurate cutting of the hoop T and separation of the terminal by cutting can be performed.

Abstract: A modular insertion unit is disclosed for use in an assembly machine for sequentially inserting electrical terminals into respective cavities of connector housings. The assembly machine has a drive means, a control module, an indexing means, and a dereeling mechanism. The modular insertion unit is connected to the machine singly or in groups, on one or both sides of a terminal strip feed path. Each modular insertion unit has a housing adapted to be selectively positioned on the assembly machine and is connected to be driven by the drive means. A terminal feed means portion of the modular insertion unit is actuated by the drive means to feed a strip of terminals from the dereeling mechanism to a severing station within the unit where a terminal is clamped, severed from carrier strips, moved to an insertion position and stuffed into a respective cavity of a connector housing. The housing is indexed with respect to the stuffing station until all cavities thereof are filled.

Abstract: This invention relates to a device for fixing fasteners to the flaps of corrugated cardboard boxes for sealing the flaps. With the fastener placed across the adjoining edges of at least two flaps, piercing nails in the form of a cow horn and attached to a pair of turnable pieces on the fastener are driven into the flaps by the device. The device is characterized in that two reciprocally movable sliders (12, 13) move to drive a cutting blade (17), causing the blade to separate a fastener from other fasteners, and subsequently drive pivotal members (29a, 29b) to depress the turnable pieces on the fastener, driving the piercing nails into the flaps. Fasteners can be fixed in place easily and reliably.

Abstract: A compact, electric, spring energized desktop stapler having a unitized housing providing both an external movable enclosure and a support frame for internal parts is disclosed. The internal power train is preferably elongated with the motor at the rear, a gear set toward the center, and low profile lever and power spring assembly at the front. The lever engages a striker with a normal upper rest position where the power spring is deflected and energized. A cam roller mounted to a final gear holds down the rear of the lever until the system is activated when the final gear rotates and the cam roller rolls off the end of the lever. In the unitized body, the base is pivotally attached to the body at the rear. A base lever selectively links to a cam roller or equivalent structure to move the body downward toward the base during a cycle.
