Patent number: 5176249Abstract: Wire stock for connecting rods is run through the nip of a pair of obliquely toothed rolls having teeth which taper from one face of the roll towards the other, and have a larger radius at the tip than along the portions flanking the tip. The angle of obliqueness matches the angle that a turn of a spiral wire will traverse the connecting rod. Round wire stock for the single-faceted spiral wires is run through the nip of a pair of rolls one of which has a cylindrical surface (i.e., a flat longitudinal profile), and the other of which has a circumferential groove with a slightly larger diameter than the round wire stock. As the wire is flattened on one side, its curved side is broadened. As the resultingly single-faceted round wire is wound into flattened spiral form, it is spatially orientationally guided, so that the facet becomes located facing outwards.Type: GrantFiled: February 8, 1991Date of Patent: January 5, 1993Assignee: The Cambridge Wire Cloth CompanyInventors: Christopher D.

The gear wheel portions are arranged in a planet gear like manner with the first pulley being laterally displaceable between a retracted position out of engagement with said rack and an operative position in which it is engageable therewith and in driving engagement with said second pulley, the displacement of the first pulley being effected by means of a selectively operated actuator means.Type: GrantFiled: December 3, 1976Date of Patent: March 14, 1978Assignee: Kosan Crisplant A/SInventor: Ole Prydtz

Patent number: 4016971Abstract: A link chain which transports and compacts tobacco leaves in a tobacco shredding apparatus has a succession of neighboring metallic links each of which has a trailing end provided with a cylindrical male coupling portion extending into and turnable in a complementary socket at the leading end of the next-following link. The socket is formed at the inner side and the coupling portion is at the outer side of the respective link. Each outer side has a convex cylindrical surface at its front end, and such surface slides along a complementary concave cylindrical surface at the rear end of the outer side of the preceding link. Each link is further formed with a scraping edge which cleans the convex cylindrical surface of the next-following link. The convex cylindrical surface of each link bounds a portion of a recess which is formed in the outer side and is adjacent to the coupling portion of the respective link.Type: GrantFiled: February 27, 1975Date of Patent: April 12, 1977Assignee: Hauni-Werke Korber & Co., KGInventors: Werner Komossa, Werner Neustadt, Gerhard Tolasch

Patent number: 4000568Abstract: A bucket dredger has a bucket chain guided over a rocker, the buckets being pivotally interconnected by links of a length shorter than the length of the frame member of the buckets. Each link has an elongated opening with rounded ends in which the pivot pins of the chain are received, the pins associated with each link being pressed apart by rotation of a threaded spindle relative to a threaded socket. The bucket frames have lubricating channels surrounding the pins and sealed against the links.Type: GrantFiled: July 14, 1975Date of Patent: January 4, 1977Assignee: N.V.

Patent number: 3982671Abstract: A potato planter having a plurality of feed tubes attached to at least one central hopper and a plurality of trailing wheels which support the planter during turning is disclosed. The novel planter is further characterized by having a pair of outboard hoppers one each attached to the outer most hopper of the central hoppers (which may be one large hopper with separated bottom bins) and outboard of the main support wheels. The potato planter preferaby has three trailing wheels wherein a pair of adjacent wheels is interconnected hydraulically through hydraulic cylinders to cause said wheels to interact mutually in regard to the terrain. The planter preferably contains an agitator for the main hopper and a secondary feed hopper which has a vibrator attached thereto for feeding potatoes to the main conveyor which transports the potatoes upwardly from the feed hopper and then downwardly to the planting position.Type: GrantFiled: August 28, 1975Date of Patent: September 28, 1976Inventor: Robert B. Curl
