Patent number: 4582179Abstract: A speed governing mechanism is provided utilizing plano-centric gearing and centrifugal braking. An outer cylindrical member serves as a cable drum and is rotated by playing out of the cable. A central shaft is fixedly mounted for supporting the assembly. Plano-centric gearing within the outer cylindrical member turns an inner rotary member on the fixed shaft at an increased speed, while a centrifugal brake assembly is fixed on the inner member and has brake shoes that fly outwardly under centrifugal force to bear against an inner cylindrical reaction surface on the outer cylinder, and thereby to limit the speed of rotation of the outer cylinder. Guides are provided coacting with the brake shoes to cause them to move rearwardly relative to the direction of rotation, and thereby to provide a wedging action with the reaction surface.Type: GrantFiled: April 25, 1983Date of Patent: April 15, 1986Assignee: Wedgtrac CorporationInventor: Bertel S.

Patent number: 4580938Abstract: Apparatus for de-palletizing and de-bagging stacks of articles such as can ends is disclosed. The de-palletizing apparatus discharges single bags of articles in seriatim order to a tilt tray comprising part of the de-bagging apparatus. The tilt tray delivers the bagged articles to a movable vertically oriented de-bagger pocket at a first or loading station. Opposed clamps engage the bottom of the bag and a pin below the bag is forced upwardly, thereby pushing the articles in the bag upwardly so as to form a void within the bag at the bag bottom. The movable pocket is then swung past a slitter station, where the bag bottom is severed and discarded. The now-severed bag and articles move to a second or de-bagging station, the bottom clamps are released, and a second set of clamps gently engages the bag. These clamps are moved upwardly to push and drag the bag upwardly from the stack of articles. As the bag moves upwardly, it is engaged in the nip of opposed rollers and drawn off and discarded.Type: GrantFiled: October 12, 1983Date of Patent: April 8, 1986Assignee: Fleetwood Systems, Inc.Inventors: Wallace W. Mojden, Robert E. Darr

Patent number: 4579135Abstract: Disclosed is a valve for preventing fuel from flowing from the vent of an automobile fuel tank comprising a valve compartment and a float vertically movable in the valve compartment, said float having a longitudinal hole communicating with vent holes made in the ceiling of the flat body or in the seat of a head fixed to the ceiling of the float body, thereby allowing the vapor of the fuel to ascend through the longitudinal hole of the float body and fill the upper space defined by the inner surface of the valve compartment and the outer surface of the head of the float thus to maintain the same pressure in the upper space as in the fuel tank at all times. Thus, the float can descend immediately when the automobile returns from an inclined position to the horizontal position.Type: GrantFiled: June 13, 1984Date of Patent: April 1, 1986Assignees: Honda Giken Kogyo Kabushiki Kaisha, Nifco, Inc.Inventors: Yoshiyasu Sakata, Shigeru Kimura

Patent number: 4579823Abstract: A sterilization indicator device comprises a receptacle for containing a spore disc and a sealed ampule of culture medium. A closure is threaded onto the receptacle and cooperates with the receptacle to provide a passageway for the sterilization gases to reach the spore disc. Upon completion of the sterilization, the closure is threaded further onto the receptacle to fracture the ampule and cause the nutrient to come into contact with the spore disc. At the same time an indicator flag is moved from an initial position to a second position to indicate that the device has been activated. Also, a seal is provided between the closure and the receptacle to seal off the spore disc from exposure to ambient air during incubation of the spore strip.Type: GrantFiled: September 27, 1983Date of Patent: April 1, 1986Assignee: Ryder International CorporationInventor: Francis E.

Patent number: 4578935Abstract: An apparatus and a method for harvesting tobacco are disclosed. Tobacco stalks are cut on the afternoon of one day and are left to lie transversely of the tobacco field. The next day, a harvesting apparatus is moved through the field and includes an elevating conveyor on which the felled tobacco plants are loaded as by a person sitting in a low seat immediately forwardly of the conveyor. The conveyor and the seat comprise a part of a trailer pulled behind the tractor, and the trailer further includes behind the conveyor a platform on which workers may stand to remove tobacco plants from the conveyor and to impale them on conventional tobacco sticks. The tobacco plants, having been lying overnight in the field, are well wilted and of much reduced weight. A wagon is towed by the trailer in close proximity thereto, and when the sticks are loaded with tobacco they are tipped toward the wagon to a position where they may be picked up by a work person on the wagon for stacking of the sticks of tobacco on the wagon.Type: GrantFiled: July 5, 1983Date of Patent: April 1, 1986Inventor: Gerald T.

Patent number: 4577373Abstract: A button collet for a tufting button comprises a one piece resilient plastic body having a projecting stem that includes a shank and a hook for receiving a tufting loop. The stem has shoulders on its opposite sides in the region of juncture of the shank and the hook. When tension is applied to the loop the forces tending to open the hook are resisted by counter forces applied against the shoulders by the loop, thereby effectively increasing the tensile strength of the collet.Type: GrantFiled: November 8, 1984Date of Patent: March 25, 1986Assignee: Handy Button Machine CompanyInventor: E. Dan Bush
