Patent number: 4831908Abstract: An improved package wind cutter utilizes a specially configured guide hook carried on the periphery of a reduced diameter winder dome to eliminate the need for a pressure roller mounted internally of the winder dome, thereby simplifying the manufacture, operation and maintenance of the apparatus and appreciably improving the strand distribution characteristics of the cutter as the relative speed of the cutter reel and winder dome are varied. The improved guide hook passes the strand from the dome to the reel with minimum separation from both the reel and the remaining pressure roller.Type: GrantFiled: January 23, 1987Date of Patent: May 23, 1989Assignee: Lummus Industries, Inc.Inventor: Fredrick A.

Patent number: 4779309Abstract: A roller gin capable of producing lint substantially free of linter fibers utilizes a wall construction to prevent the seed from contacting the ginning roll, a ginning slot in the wall through which an airflow draws the fibers. A ginning roll adjacent the slot on the opposite side of the wall grasps the fibers along a nip point formed between the roll and wall proximal the slot and urges the fibers along a path on one side of the wall while the seeds are urged along a divergent path on the other side of the wall.Type: GrantFiled: June 26, 1987Date of Patent: October 25, 1988Assignee: Lummus Industries, Inc.Inventor: Donald W. Van Doorn

Patent number: 4771665Abstract: A blade quality monitor for use with cutter reels having specifically identifiable blades utilize a sensor to detect the position of a physical anomaly on the reel. Additional sensors sense the force at the interface between the cutter reel, the material wrapped thereon and the associated pressure roller. The position of the physical anomaly is correlated with the sensed force to determine the magnitude thereof at each blade which is indicative of the condition of the blade with respect to sharpness or intactness.Type: GrantFiled: August 28, 1987Date of Patent: September 20, 1988Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4610575Abstract: Disclosed is an apparatus for removing small quantities of fiber or like material from a plurality of bales of the same arranged in rows. The apparatus comprises angularly arranged conduits, one end of which is maintained in sealing relation to another and mechanism for moving up and down one of the conduits for removing the fiber from the bales. Improved sealing means for the mechanism comprises generally flat strips of material spanning and sealing slots in the upper surfaces of the conduits together with means to run under the strip of material without losing the seal. One of such mechanisms seals the two conduits together and the other such mechanism carries the actual pickup mechanism and seals it to the conduit up and down which it reciprocates. All of the mechanisms are under control of an operator who walks up and down the aisles between the rows of bales.Type: GrantFiled: July 5, 1984Date of Patent: September 9, 1986Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4463669Abstract: A system for segregating and baling textile wastes supplied from a plurality of separate sources embodies a plurality of filling stations which receive the wastes from the separate sources. An upwardly opening portable waste receiving bin is mounted within each filling station with the lower end of each bin carrying a detachable bottom platen. A transfer mechanism moves each bin selectively, back and forth between its filling station and a compression station where the wastes are compressed within the bin. Actuator units in the compression station disconnect the bin from its platen and raise the bin to an upper position about a movable ram to thus expose the bale for final bale out.Type: GrantFiled: July 18, 1983Date of Patent: August 7, 1984Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4458381Abstract: A cotton ginning system embodying a lint cleaner in which the batt of cotton delivered to the lint cleaner is maintained at an optimum thickness even though the rate of ginning varies. The batt thickness is maintained by correlating the same with the rate of feed of seed cotton to the system. Controls are provided to assure that the batt remains at optimum thickness, and such optimum thickness is assured by sensing the rate of input of seed cotton to the system.Type: GrantFiled: January 3, 1983Date of Patent: July 10, 1984Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4369681Abstract: An inside-out cutter for material such as tow in which there is a single pressure roller, which roller has an outside diameter larger than one-half the inside diameter described by the cutting edges of the blades. The large diameter of such roller provides a gradual rather than an abrupt entrance-way for the fiber between the roller and the blades. The apparatus further is constructed to permit the movement of the pressure roller to be moved from a fiber cutting relation to the blades to a more centered position for removal of the roller from the apparatus, as when changing blades or the like.Type: GrantFiled: November 19, 1980Date of Patent: January 25, 1983Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4262390Abstract: Disclosed is an improved ginning system incorporating a roller gin and a feeder for the same. Means is provided for presenting the cotton to the roller gin substantially one lock at a time. Incorporated in the gin is means to move the ginning roller into and out of ginning relation to the ginning knife, and means is provided in the system to cause the ginning roller to move out of ginning relation to the knife whenever there is less than a predetermined amount of seed cotton in the feeder.Type: GrantFiled: May 21, 1979Date of Patent: April 21, 1981Assignee: Lummus Industries, Inc.Inventors: Robert R.

Patent number: 4261399Abstract: Disclosed is apparatus for cutting piling, trees and the like, provided with means permitting the apparatus to be placed about a pile or the like by moving it generally normal to the longitudinal axis of the pile. Specifically, the apparatus comprises longitudinal frame members carrying at one end a driven blade and at the other end a stationary blade or anvil. The stationary blade is mounted on an end cross member, one end of which is pivotally secured to one of the longitudinal frame members and the other end of which is adapted for locking to the other of the members. By pivoting the end member carrying the stationary blade upwardly or out of the general plane of the frame, the device may be opened up so that it may be slipped about a piling or tree, without having to be lowered thereabout as has heretofore been required.Type: GrantFiled: May 24, 1979Date of Patent: April 14, 1981Assignee: Lummus Industries, Inc.Inventors: James B.

Patent number: 4249850Abstract: A self-powered vehicle especially adapted for handling modules of cotton comprising a single frame which serves not only as a chassis frame for the vehicle, but also serves as a conveyor frame. Apparatus is associated with one set of wheels, either the front or rear set, to raise and lower the frame relative to that set of wheels, thus to place one end of the frame closely adjacent the ground or to a pallet on which the module rests. Apparatus also is provided to drive the vehicle and the conveyor in opposite directions whereby the module may be loaded onto the conveyor without substantial translatory movement of the module. Further details include sensors effective to limit downward movement of the loading and unloading end of the frame; and a control cab mounted immediately adjacent the loading and unloading end of the frame and displaced laterally therefrom.Type: GrantFiled: May 30, 1978Date of Patent: February 10, 1981Assignee: Lummus Industries, Inc.Inventors: Donald W.

Patent number: 4215607Abstract: The application discloses an assembly comprising an elongated knife in association with a heating unit together with means to mount the assembly so as substantially to eliminate all warping or other distortion of the knife due to heat. Specifically, the knife is mounted directly against the sheath of an electric resistance type heating unit. The heating unit and knife are mounted from a supporting frame in such fashion that they may expand or "grow" axially, thus substantially to eliminate distortion of the heating unit and knife. Also associated with the supporting framework for the heating unit and knife is means slightly to tension the sheet to be cut on either side of the knife, while the cutting takes place, thus to prevent after-cutting contact of the sheet edges with the knife.Type: GrantFiled: May 22, 1978Date of Patent: August 5, 1980Assignee: Lummus Industries, Inc.Inventors: Wilber G.
