Abstract: The present invention discloses a tapered braking device for electric winches which disposes a section of gear shaft, a section of core shaft, a wedge shape support, braking plates, an elastic element, a wedge shape piece A, a wedge shape piece B, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor can drive the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the friction faces of the wedge shape support and the wedge shape piece B and the braking plates so that the braking action stops. When the motor suddenly stops, a heavy load lifted by a tight wire rope reel provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction faces of the braking plates, so the braking effect is achieved quickly.

Abstract: The present invention discloses a plane braking device for electric winches and electric winch which disposes a section of hollow gear shaft, a section of core shaft, a fixing ring, a wedge shape support, a stopping piece, a braking plate, an elastic element, a wedge shape piece B, a wedge shape piece A, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor drives the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the adjacent braking plate and stopping piece between the braking clutch base and the wedge shape piece B, so that the braking effect disappears. When the motor stops suddenly, a heavy load lifted by a tight wire drum provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction planes of the braking plate and the stopping piece, so the plane braking effect is achieved quickly.

Abstract: The hoist device mainly contains a gear assembly and a ratchet braking assembly. The gear assembly mainly contains a chain wheel driven by a main axle running through the ratchet braking assembly which mainly contains a ratchet wheel sandwiched between a pair of brake rings. The ratchet wheel, controlled by stopping blocks, can only turn in one direction. At an end of the main axle, there is a hexagonal cylindrical sleeve so that either an ordinary wrench or a power tool can be used to turn the main axle. As the main axle is turned to lift an object, the ratchet wheel clamped by the brake rings is turned as well. When the main axle is turned to the other direction, the brake rings release the ratchet wheel so that it will not prevent the chain wheel to lower the object.

Abstract: A boat lift braking system includes a threaded shaft driven by the boat lift motor. A torsion tube disposed about the shaft carries an interiorly threaded nut that interengages the peripheral threads of the shaft. A rotor is mounted to the nut adjacent a brake pad that is supported by a ratchet component. A pawl mechanism cooperates with the ratchet component for limiting rotation of the ratchet component in a first direction and permitting rotation of the ratchet component about the shaft in a second direction. The torsion tube is connected through a reduction apparatus to the winder of the boat lift. When the lift is at rest, a torsion spring drives the torsion tube and rotor against the brake pad and the ratchet component interlocks with the pawl mechanism to hold the lift at a desired elevation. When the motor is driven to lower the lift, the shaft is driven within the torsion tube such that the rotor momentarily disengages the pad.

Abstract: A boat lift uses a one-way roller bearing in association with a friction disc clutch. A hand-wheel operator provides power input, though a motor may be substituted therefore. A gearing arrangement, a one-way roller bearing and friction clutch, a cable and cable reel for selectively providing tensile force, and a boat support such as a custom hull support or suitable adjustable or universal boat support round out the lift components. Novel couplings permit the handwheel to be rotated and translated axially.

The unwinding side of the engagement groove is formed at the fitting plane while the winding-up side thereof is formed on the inclined surface.

Abstract: In an electric chain hoist, there is a slipping clutch in the drive line which connects the electric motor to the chain sprocket, the slipping clutch acting as an overload safeguard. A holding brake is also provided to hold the drive line in the braked state when the motor is switched off. The brake exerts its braking action primarily on that part of the drive line which lies between the slipping clutch and the chain sprocket. To prevent the slipping clutch from entering the slipping state when the motor is switched on before the brake has been released to a sufficient extent, the brake is designed in such a way that it acts on both parts of the drive line.

Abstract: A chain hoist contains a slipping overload clutch in the drive line which connects the electric motor to the chain sprocket. This slipping clutch has two clutch halves which are in frictional engagement with one another and are preloaded into frictional engagement with one another by a spring. A holding brake is furthermore provided and this holding brake acts against the clutch disks so as to increase the frictional grip between the clutch disks in the applied state. This ensures that when the hoist is started and the disengagement of the brake is delayed, the slipping clutch does not enter the slipping state.

Abstract: A winch for retrieving and releasing rope or cable that is attached to a boat hoist or the like in order to lift or lower a boat located on the hoist. The release of the boat hoist to lower the boat into the water or the like is thus carried out safely and under controlled conditions.

Abstract: A function selector knob for selecting a free-chain function is provided with a selectively positioned bias dog which contacts a brake driving gear threadingly engaged on a pinion shaft, alternatively biasing the gear in a brake engaging or brake release direction as determined by an over center spring disposed between a selector knob and a pinion supported stop.

Abstract: A winch, for example, for winding in and paying out a cable attached to a person in a hazardous situation, for example underground, comprises a pair of axles mounted on a frame, one of the axles carrying the cable drum for rotation therewith. Two safety brakes are provided, one on each axle, and each including a cam actuated clutch so that rotation of the drum in the pay-out direction is only allowed when the axles are driven in the pay-out direction. A handle for driving the axles includes two hand grasp portions for different mechanical advantage. The handle can be located at two different positions on a drive sprocket on one of the axles or on a second drive sprocket freely rotatable on the first axle for different drive ratios.

Abstract: The apparatus spools a line carrying a weight for positioning a fishing lure at a desired depth in water for trolling. The apparatus has a motor which rotates a spool carrying the line supporting the weight. A brake automatically brakes the spool when the spool starts to unwind the line, which can occur when the motor is inoperative. Braking force on the spool can be finely adjusted to permit slipping and controlled unwinding, so that the line does not break should the weight become fouled or hung up on the bottom. Preferably, when winding up the weight, a clutch transmits torque between the motor and spool when the torque is below a slipping threshold torque. However, the clutch slips when the slipping threshold torque is exceeded and simultaneously generates an audible warning sound when slipping to protect the motor from overload if the weight becomes "hung up" when winding in. An alternative electrical circuit breaker can be substituted for the clutch to protect the motor.

Abstract: A fishing apparatus having a main frame comprising of a center post having a sprocket wheel rotatably mounted on its upper end. There is further provided a frame extending from the center post for housing a second sprocket wheel, the two sprockets interconnected via a continuous link chain, so that rotation imparted onto the main sprocket imparts rotation to the secondary sprocket. The secondary sprocket is rotated in unison to a reel member housing a quantity of fishing line to be reeled in and out depending on rotation of the sprocket wheel. There is further provided a braking frictionally braking to the reel upon movement of the chain in a certain direction. Likewise, upon slight movement of the chain in the second direction the secondary sprocket wheel becomes a free rolling wheel and will allow a line to be reel therefrom.

Abstract: This invention provides automatic fishing apparatus for trailing line fishing. The trailing line is supported on a reel which is adapted to be coupled or uncoupled with driving means to enable the line to be reeled in or let out. The selective coupling of the reel with the driving means is in response to variations in the line tension caused by a fish being hooked on the line.

Abstract: The present invention relates to an automatic motorized fishing reel which includes a frame and a spool rotatably coupled thereto for receiving and storing fishing line thereon. An electrical motor is coupled to the frame for rotating the spool in a direction for winding the fishing line onto the spool. The motor also induces a drag upon the rotation of the spool while the spool is unwinding. A clutch is operably interposed between the spool and the electrical motor for enabling the spool, when in a first condition, to rotate in the direction for unwinding the fishing line therefrom. When in a second condition the clutch provides positive engaging connection between the spool and the electrical motor for producing mutual corresponding rotation therebetween. The clutch switches between the first and second conditions responsive to a substantial torque differential exerted between the spool and the electrical motor.
