  • Patent number: 9918589
    Abstract: Provided is a food stir-frying machine that makes it possible to surely and smoothly rotate a stirrer while bringing the stirrer into elastic contact with the inner surface of a pan, and increase the durability of the stirrer. A stirring device has: a supporting member that supports a rotary shaft; a stirring frame that supports the supporting member through a horizontal shaft in a direction in which a stirrer is moved in or out of a pan; and a device frame that vertically swingably supports the stirring frame in order to evacuate the stirrer upward, and between the stirring frame and the supporting member, biasing means adapted to bias the supporting member toward the pan side so as to bring the stirrer into contact with the inner surface of the pan.

  • Patent number: 5042741
    Abstract: A reverse rotation preventing mechanism for a fishing spinning reel having a reel body, a rotor, and a main shaft, comprises a ratchet wheel mounted on the rotor within the forward recessed portion of the rotor, and a stop pawl selectively engaging with the ratchet wheel. The stop pawl is formed integrally with a shaft portion which passes through a wall of the reel body. The reverse rotation preventing mechanism also includes an operation member for controlling an engaging condition of the stop pawl with the ratchet wheel. The operation member is provided in the rear portion of the reel body.

  • Patent number: 4907759
    Abstract: A spinning reel assembly for use in fishing includes a spool shaft mounted to a spinning reel casing but movable rearwardly and forwardly, a spool for winding fishline on having an interior bore for receiving the spool shaft, and a plurality of drag plates secured within the bore, some of which may be integral with the spool. A drag adjustment knob is threaded onto the spool shaft for applying an axial force to the drag plates in order to brake the spool against rotation.

  • Patent number: 4807828
    Abstract: Herein disclosed is a fishing reel comprising a spool rotatably mounted on a reel frame, a non-magnetic conductor in a cover member of the reel frame and fixed to the spool, and a brake mechanism for producing an eddy current in the non-magnetic conductor to dampen the rotation of the spool. An adjuster is movably provided in the cover member for adjusting a dampening force of the spool when a fishing line is paid out from the spool. A dampening force adjusting dial for actuating the adjuster is mounted a rear upper portion of the cover member so that the operator's thumb is readily accessible to the adjusting dial. The fishing reel may comprise an indicating device for indicating the dampening force applied to the spool.

  • Patent number: 4778124
    Abstract: A spinning reel for fishing wherein the reciprocating spool has a rearward flange which is engaged with rollers supported on support rods which are attached to the surrounding rotor and bailing mechanism. In this manner, a fishing line is prevented from dropping behind and off of the reciprocating spool when either fishing line is wound onto or cast off of the spool.

  • Patent number: 4702430
    Abstract: A braking device for the spool of a fishing rod is disclosed which contains two separate braking adjustments. The first braking adjustment adjusts the coarse breaking force. The second braking adjustment adjusts a finer braking force. The embodiment discribed uses two springs to bias braking boards to friction boards, the two springs being adjustable separately. The first spring is adjustable by varying the linear displacement of an adjusting cylinder which is threaded into a portion of the fishing spool apparatus. A second adjusting mechanism uses a cam with a varying radius pending on the location of the cam. This varying radius is biased against a leaf spring, thus varying the displacement of the one end of the lead spring depending on the location of the variable cam.

  • Patent number: 4516348
    Abstract: An information system for trawler operation includes a radio link between the bridge or other vessel control station and each of a plurality of fishing devices on the vessel. Each fishing device has a radio transmitter that sends signals from which the vessel operator can determine for such fishing device, such variables as line speed, line tension, line payout and the like. Suitable sensing mechanisms are provided together with appropriate electrical circuitry.

  • Patent number: 4513925
    Abstract: A drag brake for a spinning reel includes a stack of friction disks accommodated in a cup. A member threadedly mounted in the cup adjusts the braking force through a resilient element. The brake adjusting member is stopped in its outward retracting movement by a transverse spring extending across and mounted by the cup. A knob is attached to the end of the brake adjusting member and has an internally corrugated skirt that surrounds the cup. The spring projects beyond the cup to engage the corrugations yieldingly to maintain the setting of the brake.
