  • Patent number: 6719275
    Abstract: A drive assembly (22) for a policy (26) comprises a first pulley (26) having a cable (20) passing around part of the pulley circumference. Three relatively small pulleys (30, 32, 34) are mounted on the assembly body (24) and a belt (36) extends around the pulleys. The belt (36) is driven and two of the small pulleys (30, 34) are located on a chord of the first pulley (26) such that tension in the belt (36) tends to bias the belt (36) to bear against the cable (20) as it passes around a portion of the circumference of the first pulley (26) located between the two small pulleys (30, 34). In a further embodiment, a convex support surface (70; 86) is formed by a belt (62) or rollers (92), rather than by the pulley (26). In another embodiment an assembly (150) may be used to drive a ground engaging wheel (164) of an aircraft or vehicle, rather than a pulley wheel (26).

  • Patent number: 6702217
    Abstract: A recording tape cartridge used with a drive device that includes a pull-out member connectable at an end of a recording tape accommodated in the recording tape cartridge to pull out the recording tape. The recording tape cartridge comprises the recording tape, a case for accommodating a single reel wound with the recording tape and a leader member fixed at the end of the recording tape and having claw members that connect to the pull-out member when the recording tape is being pulled out. The claw member engages with a circulating groove formed at the pull-out member by the pull-out member being pressed against the leader member, and the claw member disengages from the circulating groove by a subsequent pressing, thereby allowing the end of the recording tape to be joined to and released from the pull-out member.

  • Patent number: 6655619
    Abstract: Reciprocating mechanism for a spinning-reel, which reciprocates the spool in response to rotation of the rotor, has a worm, a slider, an intermediate gear, a first guide shaft, and a second guide shaft. Crisscrossing helical grooves are formed in the outer circumference of worm, which is rotatively supported by the reel unit. Slider, which is coupled to the spool, has an engagement pin that engages helical grooves, and a slider body that has a mounting hole that pivotably supports engagement pin such that engagement pin engages helical grooves from radial outside of worm. Intermediate gear transmits rotation of rotor to worm. First and second guide shafts guide slider in the direction of spool shaft. First guide shaft is disposed on a side of engagement member opposite the side closer to worm. With the present invention, it is possible to reduce the size of reciprocating mechanism.

  • Patent number: 6651916
    Abstract: Spinning-reel bail-tripping mechanism is a device for returning bail arm from line-releasing posture to line-retrieving posture as rotor rotates in line-retrieving direction. Bail-tripping mechanism includes shifting member that shifts front-to-rear as bail arm pivots; toggle-spring mechanism that urges and toggles bail arm to between the two postures; switching portion, and restraining mechanism. Switching portion comes into contact with the rear end of shifting member and shifts shifting member toward a first position. Restraining means restrains bail arm from returning into line-retrieving posture when bail arm is in line-releasing posture. Restraining means also releases restraint before the rear end of shifting member reaches the peak edge of first inclined face of switching portion as rotor rotates in line-retrieving direction while bail arm is in line-releasing posture.

  • Patent number: 6651960
    Abstract: A frame assembly that fits into the hitch receiver box found on many trucks. It has reinforced vertical plate attached to the outer end of an accessory tube. The vertical plate has a series of lugs attached to the top sides of the plate. A pulley is mounted below the lugs. The lugs hold the bottom of a standard car jack, which has a lift plate and is operated by a handle. Wire rope is attached to an eye in the lift plate. The wire rope passes around the pulley. The winch works by placing a jack in the lugs and attaching the wire rope to the eye. The other end of the wire rope is secured to an anchor chain that is secured to a substantial object, such as a tree. As the jack is operated, it pulls on the wire rope, which moves a vehicle.
