Patent number: 8973902Abstract: A power winch horizontal-pull clutch device provides dynamic forces from a power source and uses a deceleration device to retard the force transmission to a cable pulley for releasing and rewinding a steel cable on the cable pulley. A connecting slot is formed on a casing of the deceleration device. The deceleration device includes an outer ring body and at least one insert slot formed on an external surface. The power winch includes a clutch device for selectively fixing the connecting slot to the insert slot to transmit the dynamic force from the deceleration device to the cable pulley. The clutch device is a sealed assembly and a control handle is provided for making a horizontal movement to achieve the clutching effect and prevent water, dust or other foreign matters from entering into the clutch device, damaging components, causing failure or malfunction, or clamping an operator's hand or foreign matters.Type: GrantFiled: December 21, 2012Date of Patent: March 10, 2015Assignee: Comeup Industries Inc.Inventor: Shih Jyi Huang

Patent number: 8056883Abstract: A manual storage lift system for efficiently hoisting articles to a raised position for providing temporary or permanent storage for the articles. The manual storage lift system generally includes a drive unit including a mounting plate mounted on a vertical surface, a shaft rotatably connected to the mounting plate, a spool coaxially positioned along the shaft, wherein the spool rotates independently of the shaft, at least one elongated member wound upon the spool, a hand crank connected to the shaft for winding or unwinding the at least one elongated member upon the spool and a brake assembly mounted to the drive unit, wherein the brake assembly includes a torsion spring. A first force applied with the hand crank in a rotational direction upon the torsion spring lessens a tension of the torsion spring allowing the torsion spring and the spool to rotate.Type: GrantFiled: May 4, 2009Date of Patent: November 15, 2011Inventor: Scott Brockie

Patent number: 7878483Abstract: Ship's winch including a frame which can be attached to a vessel and on which the cable drum and the motor driving the cable drum are provided. Adjacent to the cable drum, a slipping clutch is provided and between slipping clutch and the motor, a freewheel mechanism is provided which works towards the frame. The slipping clutch is embodied not to transmit further load to the freewheel mechanism or motor, respectively, in case of a certain overload caused by tension in the towing cable. In addition, by positioning the freewheel mechanism/clutch in this manner, the motor output for pulling in a certain load under greatly varying stresses can be reduced.Type: GrantFiled: January 18, 2008Date of Patent: February 1, 2011Assignee: Machine & Lierenfabriek C. Kraaijeveld b.v.Inventor: Markus Van Der Laan

Patent number: 5842659Abstract: Lever actuator assembly includes the use of at least one clutch member for providing selective adjustment of the length or tension of a cable. The clutch member provides for a stationary position of a item such as a cable relative to the assembly housing absent any rotational force. Applying a rotational force in a selected manner results in an adjustment through movement of the clutch member relative to the housing. A disclosed embodiment is particularly useful for applications that require adjusting a relative length of a cable.Type: GrantFiled: October 24, 1997Date of Patent: December 1, 1998Assignee: McCord Winn Textron Inc.Inventors: James T. Ligon, Sr., Stephen P. Porter, Andrew L. Patrius, Jr.

Patent number: 4715583Abstract: A tensioning device for use with an endless traverse which is longitudinally adjustable in both directions responsive to a rotational drive. The rotational drive includes two driving gears which are each selectively coupled with a drive shaft so that when one of the driving gears is positively driven, the other driving gear is permitted to rotate freely. The traverse changes from one driving gear to the other by passing from between a pair of overlying side walls and over a flange. Elongation resulting from strain of the traverse is continuously led out of the system so that blocking or braking of the traverse is avoided. The tensioning device is especially suitable for the operation of strip curtains or conventional curtains, as well as for curtain systems with large and heavy traverses.Type: GrantFiled: February 8, 1985Date of Patent: December 29, 1987Assignee: K. Bratschi, Silent GlissInventor: Hans Grutzner

Patent number: 4447044Abstract: A control system for one or more hydraulically driven crane winch drums each having a hydraulically actuated clutch and a brake. Included is a negative braking mechanism having a brake cylinder of the single-acting, spring-return type for normally holding the brake applied by the force of the spring and releasing the brake on fluid pressure actuation. A mode selector valve selectively delivers hydraulic fluid under pressure from two separate sources to the clutch and the brake cylinder in order to condition the winch for a selected one of winching, brake-locking, and free-fall modes. The mode selector valve causes the negative braking mechanism to release the brake in the free-fall mode, so that a positive braking mechanism is also provided to permit the operator to arrest the free fall of the load, or the free running-out of the cable, in an exact position desired.Type: GrantFiled: May 26, 1981Date of Patent: May 8, 1984Assignee: Kabushiki Kaisha Komatsu SeisakushoInventor: Minoru Nakata
