Abstract: A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

Abstract: The invention relates to a power tool, in particular a hand power tool (1), comprising an electric drive motor (2) which may be operated by means of a motor switch element (8) and a gearbox (3) driven by the drive motor (2), with a first and at least one second speed. According to the invention, the motor switch element (8) is coupled to the gearbox (3) such that the same can be switched from the second speed to the first speed by means of the motor switch element (8).

Abstract: An apparatus for automatically binding reinforcing rods including a case having a predetermined shape at which reinforcing rods are forwardly attached, a binding-wire supplying device formed at a rear part of the case, a binding-wire feeding device for advancing the binding-wire, a rotary binding-wire guiding device, a binding-wire cutting device, and a binding-wire twisting device.

Abstract: A hand tool capable of wrapping and unwrapping wires on terminals is provided with a an electrically-insulating drive housing or adaptor and coupling which insulate the bit, and sleeve if present, and driver from the housing and the gear train thereby protecting the user in case of accidental contact between the housing and an active electrical source while the tool is being used. The coupling tightly couples together divided drive shaft portions to maintain the electrical isolation.

Abstract: A torso exercise machine includes a frame designed to rest upon a floor surface; a seat pivotally mounted on the frame; at least one handlebar pivotally mounted on the frame; and a link pivotally interconnected between the seat and the handlebar. The link constrains the seat and the handlebar to pivot in opposite directions relative to the frame. A resistance device may be interconnected between the handlebar and the frame to resist pivoting of the handlebar and the seat toward one another.

Abstract: A tool capable of wrapping and unwrapping wires on terminals is provided with a quick-release mechanism to allow rapid and simple replacements of bits and sleeves used for the wrapping and unwrapping functions. This feature uses a bit driver comprising a camming surface that cooperates with a collet having a tapered split end for holding the bit and sleeve loosely or a gripping relationship for driving the bit. A novel bit/sleeve combination is capable of wrapping wires on terminals when rotated in one direction and unwrapping wires from terminals when rotated in the opposite direction. The tool also features a motor reversing switch for allowing the tool to be used both for wrapping and for unwrapping wires, with the reversing switch located in a protected region at the rear of the tool to prevent accidental activation. The same tool housing can also be used for fabricating both battery operated as well as AC operated tools.

Abstract: An improved wire wrap tool having a motor, a power supply and a power circuit, the improvement comprising means for shielding the motor in a manner that prevents the tool from emitting undesired amounts of electromagnetic interference and means for damping transient voltage spikes in the power circuit.

Abstract: A drive unit for a power tool has a motor driven output gear rotatable about an output axis, a rotatable carrier plate, and a plurality of idler gears rotatably mounted on pins affixed to the carrier plate such that the gears engage the periphery of the output gear. The unit includes a drive shaft supported at one end by the carrier plate, and a non-rotatable ring gear floatingly mounted for engagement with the idler gears, whereby rotation of the output gear is coupled to the drive shaft, and hence to the tool bit, through the carrier plate and the carrier plate is urged toward rotational alignment with the axis of the output gear through the action of rotational forces.

Abstract: A fence wire winder for twisting together two strands of wire includes a single-piece handle member with a clearance aperture disposed in one end and a generally cylindrical spindle member extending through this clearance aperture. Secured to this spindle member is a knurled ratchet wheel and secured to the handle member is an engaging, spring-loaded pawl. The action of the pawl relative to the knurled ratchet wheel permits the handle member to be locked to the spindle member so that the two members turn together in a first direction of rotation while in the reverse direction of rotation, the handle member freely moves relative to the spindle member which remains stationary. The spindle member is retained in position by the knurled ratchet wheel on one side and a washer and retaining thimble arrangement on the opposite side. Disposed within the spindle member and extending therethrough is a longitudinal clearance channel for receipt of a first strand of wire.

Abstract: A wire wrapping tool (10) includes a gun (20), a bit (24) for cutting, stripping and wrapping a wire (21), a sleeve (25) for receiving the bit and a wire softening device (26). The device (26) includes a pair of opposed rollers (28,30) for softening the wire (21) pulled therethrough.

Abstract: A winding and cutting device for winding a wire on a connection pin of electrical components, and for the purpose of cutting off the excess remaining wire in one work cycle. A stationary sleeve is provided with a rotatable mandrel which has a central bore which is open at least in the direction of its one front face into which the pin is inserted during winding and which has, at least in the winding area, a diameter corresponding at least to the winding diameter. The sleeve and the mandrel have a slanted slot which is open at least in the direction of the one front face and which is aligned relative to the bore.

Abstract: In a hand-held power tool (10) for wrapping conductor around an electrical terminal, a drive means (14, 34 and 42) is selectively engaged with a clutch (58) mounted on a drive shaft (44) journaled within index means (62) in axial arrangement within a case (12). The drive means (14, 34 and 42) and index means (62) are secured to the case (12) by means of circular tongue and groove structure of radially stepped configuration. Resilient ring members (60) are frictionally engaged between the drive means (14, 34 and 42) and the drive shaft (44) to provide for gradual arrest of the drive means after disengagement of the clutch means (58) and stoppage of the drive shaft by the index means (62). A trigger (22) within the case (12) controls actuation of the drive means (14, 34 and 42) and engagement of the clutch means (58) therewith.

Abstract: An electrical tool, especially for hand use, which can function to strip the insulation from electrical wire, wrap the stripped end about a terminal, and unwrap the stripped end to remove the wire from the terminal is described. The wrapping and unwrapping bits extend from opposite ends of a common handle, on which the stripper is mounted. Features include novel wrapping and unwrapping bits, and the stripper construction.
