Patent number: 4932602Abstract: 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.Type: GrantFiled: July 15, 1988Date of Patent: June 12, 1990Assignee: Scott Plastics Ltd.Inventor: Blayney J. Scott

Patent number: 4928464Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.Type: GrantFiled: April 21, 1987Date of Patent: May 29, 1990Assignee: Burlington Industries, Inc.Inventor: Elbert F. Morrison
