Patent number: 4944647Abstract: A high capacity machine cuts the tops of plastic bottles and inverts the bottles for discharging their contents. Bottles are conveyed through the machine by a feed screw. At the cutting station means are provided for standing the bottles erect so that they engage a stationary knife just below the top for cutting off the caps. Guides downstream from the cutting station maintain the bottle in the screw and invert it underneath the screw for dumping. The cap is not completely severed but a minor portion of the circumference is left intact to serve as a hinge between the cut bottle and cap. The cap is kept more or less erect as the bottle is inverted to avoid interference with discharge of the contents. At the cutting station a support screw is rotated synchronously with the feed screw by interengaging teeth on the crests of the threads of the two screws.Type: GrantFiled: April 29, 1988Date of Patent: July 31, 1990Assignee: Alpha Therapeutic CorporationInventors: John C. Oleson, Steven K. Teske, Richard F. Iturzaeta, Erwin E. Langer

Patent number: 4875309Abstract: This relates to a disc cleaning machine wherein abrasives are thrown at a disc as it travels along a predetermined path and wherein the disc is rotated as it travels along that path. A principle feature of the machine is that discs are conveyed along a path by a pair of cooperating screw type conveyors while the discs are supported on a pair of support shafts which rotate and rotate the discs so as to ever changingly present surface portions of the discs to the abrasives. The workpieces are automatically fed into the machine by way of a notched feed wheel and at the end of the cleaning operation, the workpieces drop off of the support shafts and down a discharge chute so that the operation is automatic.Type: GrantFiled: December 17, 1987Date of Patent: October 24, 1989Assignee: Pangborn CorporationInventor: William W.

Patent number: 4865158Abstract: A vertical bale elevator to transfer bales of hay, straw or the like between the ground and a barn has an elongated frame with two opposing augers mounted on opposite sides of the frame. The frame contains a guide for the blades. The augers are mirror images of one another and rotate in opposite directions to force a bale upward and rearward within a frame. The guide is arranged to receive a bale in the bottom section and discharge the bale in the top section. The augers are powered by a single power source that can be reversed to move bales down the elevator rather than up. When operating in reverse, it is usually desirable to make changes to the guide. The middle sections are made in various lengths so that the total height of the elevator can be varied. With previous elevators, a chain rotates upward at a back and front of the elevator. These previous elevators are much more complex.Type: GrantFiled: February 3, 1988Date of Patent: September 12, 1989Inventors: Robert W. Checkly, Rudy B. Nielsen

Patent number: 4621971Abstract: A means for rotating tree trunks or equivalent into correct position regarding their curvature, prior to their feeding into a machine processing round timber. The means is primarily intended to be used as an ancillary in a timber feeding means which feeds the tree trunks into a processing machine, because branch stubs which have remained on the tree trunk may impede the turning of the tree in the feeding means. The means of the invention has been carried out in such manner that the means comprises one or several rotator pairs, each such pair being composed of two rotators provided with a helix and disposed in the tree trunk feeding means, and which in their operating position are elastically urged against the tree trunk and which are arranged to rotate with reference to each other so that the tree trunk therebetween rotates, forced by the helices, in the desired direction.Type: GrantFiled: April 23, 1985Date of Patent: November 11, 1986Inventor: Kauko Ratuio
