Abstract: The coil winding machine (10) winds a series of interconnected coil bundles within winding forms (28). The winding forms are transferred from a coil winding station (29), at which the coil is wound in the pie-shaped cavity of the winding form, to a coil removal station (237,293,61), at which the winding form is separated and the coil is removed and placed on a storage arbor (54) in the proper order for later assembly in a transformer, and finally, after reassembly of the winding form, back to the winding station.

Abstract: A multistation charging system is provided for charging batteries within a plurality of cordless tools, appliances or the like, each of which has at least one rechargeable battery therein. A plurality of modules, which act as charging stations, are arranged substantially adjacent to one another. Normally closed pairs of conductive contacts are provided in each of the modules. The electrical pairs of contacts in the modules are connected in a series circuit arrangement with each other. On one of the modules, electrical connection is provided to a single current regulated solid-state charging device which produces charging current pulses. The device may alternatively be in the one module. Each of the modules removably supports a respective tool or appliance and each tool or appliance has means for electrically connecting the respective battery therein within the series circuit arrangement and in series therewith only one wall outlet or a.c. power connection is required.

Abstract: A charger for batteries includes a a charging station, which includes a housing. A casing end having an open portion through which batteries to be charged are to be inserted is provided. A constant tension spring within the casing urges the batteries outwardly of the casing. A lid is provided adjacent to the open end of the casing, the lid being movably, pivotably supported on the casing. A stop member is provided on the housing, the stop preventing the lid from being moved to its completely open position when the casing is supported on the housing. A latch arrangement retains the lid in a closed orientation. The batteries in the casing are retained therein by a portion of the lid whenever the lid is pivoted away from its completely open position. Contact means are provided between the housing and casing to provide a path for charging current. A multiple of charging stations can be provided, the multiple stations being electrically and mechanically connected.

Abstract: An impact-delivery tool (20) includes a motor-driven gear (72) which supports for continuous rotation therewith a relatively shiftable drive pin (80). The drive pin (80) is selectively shifted to couple the rotary drive of the gear (72) to a reciprocably operable, impact drive bar (76). An interrupt mechanism (78) which detects workpiece engagement by the tool (20) and operator actuation of the tool, both necessary for tool operation, controls the coupling and decoupling of the drive pin (80) relative to the drive bar (76). The interrupt mechanism (78) provides selective processing of the tool (20) through an impact delivery power stroke and a return stroke while also precluding successive power strokes.

Abstract: A battery-operated device having a passive charging mode and an active discharging mode is combined with a support, which supports the device in its charging mode. The support is integral with a plate which is to be positioned on a wall. The plate may be a replacement cover plate which may be substituted for a cover plate of a conventional A.C. wall outlet. The device includes a short power cord having a plug at its distal end. A D.C. current pulse producing circuit, preferably a solid state integrated circuit is housed within the plug. The D.C. current pulse producing circuit is especially useful as a battery-charging circuit.

Abstract: A charger for batteries includes a housing having an open portion through which batteries to be charged are to be inserted. A constant tension spring within the housing urges the batteries outwardly of the housing. A cover is provided adjacent to the open portion of the housing, the cover being movably, pivotably supported on the housing. A pair of spaced-apart contact prongs are provided, at least one of which is carried by the movable cover, thereby preventing electrical connection to the prongs wherever the cover is moved away from the open portion of the housing. A latch arrangement retains the cover in a closed orientation. The batteries in the housing are retained therein by a portion of the latch whenever the cover is pivoted away from the open portion of the housing. One of the contact prongs is carried by the cover and moves therewith. A solid-state charging circuit within the housing is connected to the other one of the contact prongs.

Abstract: A fastener tool having a housing in which is mounted a universal motor to be continuously operated during operation of the tool. A gear driven by the motor is a rotary driven member. A drive pin is carried by the gear to rotate therewith and is free to be shifted axially relative the gear. A drive bar is mounted in the housing to drive fasteners. The drive pin is connectable to the drive bar to produce a power stroke and a return stroke. An interrupt mechanism is operative to prevent successive power strokes, and in the preferred embodiment it will include the drive pin; it will act to disconnect the drive pin from the drive bar. Also the interrupt mechanism will control the connection of the drive pin and drive bar. The maximum number of power strokes are one-half the number of rotary cycles of the rotary driven member. The interrupt mechanism includes a linkage for sensing workpiece engagement and operator actuation of the tool, each of which are required to produce a single power stroke.
