Patent number: 6615455Abstract: A fiber opening device comprising a feed section opening into the fiber opening section. The opening section includes a cabinet with an inner chamber, a waste removal chamber and a fiber web removal unit. The inner chamber includes a doffing roll and a contaminant collecting area located above first and second opening rolls. A main roll is located beneath and between the opening rolls and a waste removal section and a fiber web removal section are located beneath the main roll. In operation, fibers delivered into the inner chamber are first acted on by primarily one of the opening rolls which creates a tumbling action in which contaminants are dislodged and deposited into the contaminant receiving area while other fibers are picked up by the second opening roll carried to and doffed onto the main roll forming a fiber web for delivery to the fiber web removal section.Type: GrantFiled: September 16, 2002Date of Patent: September 9, 2003Inventor: Akiva Pinto

Patent number: 6088881Abstract: An apparatus for separating foreign matter from fiber tufts includes an air duct in which fiber tufts are pneumatically conveyed into the system via a high speed air stream. The air duct provides an air stream that conveys the fiber tufts with trash on to a revolving cleaning cylinder having teeth to engage the fiber tufts at a velocity that is sufficient to prevent agglomeration of the fiber tufts on a cylinder. The fiber tufts and trash thereby engage a separating means without agglomeration of the fiber tufts. The fiber tufts and trash further engage a streamer plate and grid bars to separate the trash from the fiber tufts such that the clean fiber tufts are distributed to a lint flue. The apparatus may further include a perforated cylinder in close proximity with the revolving cleaning cylinder that allows air to flow there-through, but that prevents penetration of the perforated cylinder surface by the desired fiber tufts.Type: GrantFiled: September 29, 1998Date of Patent: July 18, 2000Assignee: Lummus CorporationInventors: Donald William Van Doorn, James Brown Hawkins

Patent number: 5890264Abstract: An aeromechanical individualizer for individualizing entities within a fiber sample includes a cylindrical rotating beater wheel, having a non-permeable cylindrical surface and having carding elements, such as pins or wire points, on the cylindrical surface. A cylindrical feed roller and feed plate supply the fiber sample to the beater wheel in the form of a beard at a first point along the rotational path thereof. A nozzle directs a gas flow across the feed plate and the beard such that fibers are dragged from the feed plate into engagement with the carding element. At a second point along the rotational path of the beater wheel there is a doffer for removing entities of the beater wheel. An enclosure surrounds the beater wheel and substantially prevents the ingress or egress of the gas except gas flow which enters via the nozzle at the first point and which exits at the second point.Type: GrantFiled: October 6, 1997Date of Patent: April 6, 1999Assignee: Premier Polytronics LimitedInventors: Frederick M. Shofner, Christopher K. Shofner

Patent number: 5414900Abstract: The present invention is drawn to fiber cleaning utilizing an alternating series of cleaning saw cylinders and doffing brush cylinders. The doffing brush cylinders transfer ginned fiber from an upstream cleaning saw cylinder to the next downstream cleaning saw cylinder in such a way that the flow of the fiber changes direction at the pinch point between the downstream cleaning saw cylinder and the doffing brush cylinder. Guiding means including control bars are provided to help guide the ginned fiber from the doffing brush cylinder to the next downstream cleaning saw cylinder at the pinch point. Flow deflecting means including air control bars are provided to deflect a substantial portion of the flow of entrained air from flowing around the doffing brush cylinder.Type: GrantFiled: February 15, 1994Date of Patent: May 16, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Marvis N.

Patent number: 5155886Abstract: An arcuate baffle wall is provided within a conventional lint cleaner forward of and horizontally registered with the front side of the saw cylinder of the lint cleaner. The upper and lower extremities of the baffle wall are generally horizontally registered with the upper and lower extremities of the saw cylinder and the baffle wall is spaced generally midway between the forward periphery of the saw cylinder and the front wall section of the lint cleaner to thereby define a venturi passage for air flow at appreciably increased velocity downward over the grid bars of the lint cleaner spaced about the forward peripheral portion of the saw cylinder. The venturi passage greatly increases the velocity of air flow past the grid bars and prevents the build up of cotton lint thereon to the extent that tangential outward displacement of dirt from the saw cylinder is blocked.Type: GrantFiled: July 11, 1991Date of Patent: October 20, 1992Assignee: Texoma Machine, Inc.Inventors: Kenneth D. Schrader, James A. Nichols

Patent number: 4601084Abstract: A means for adjusting the clearance between the grid plate assembly and the drum of an extractor of the type which separates trash from cotton lint as it passes through this clearance. The present means is easily and quickly installed on commercially-available extractors or new extractors and is fully operable from outside the housing of the extractor. The adjusting means comprises a pair of supports or brackets which are positioned on the outside of a side wall of the extractor housing. One of the brackets is fixed to the wall while the other bracket is connected to the grid plate assembly by a bolt that passes through an elongated slot in the wall. The two brackets are connected together by an adjustable member (e.g. all-thread bolt) having jam nuts thereon which, in turn, can be moved along the adjustable member to thereby allow the other bracket and, hence, the grid plate assembly to move either toward or away from the drum to change the clearance therebetween.Type: GrantFiled: June 13, 1985Date of Patent: July 22, 1986Inventor: Hurston B.

Patent number: 4505005Abstract: A grating composed of individual bars is provided for an opening roller serving for cleaning of fibers and provided with clothing. Each bar carries a guide element extending over its length and comprises a guide sheet, the spacing of which from the clothing is settable. For the purpose of adjustment, the guide element comprises a flat band portion which rests on a side surface of the bar, is shiftable substantially parallel to such side surface and is releasably secured to the bar. In known devices, setting of the spacing x of the guide sheet from the clothing is laborious because the accessibility to the position to be measured is difficult. In accordance with the invention this is avoided in that each guide element is additionally provided on the longitudinal side of the flat band portion directed away from the guide sheet with a band portion which is inclined with respect to the flat band portion, extends in the longitudinal direction of its bar and covers the back thereof.Type: GrantFiled: October 11, 1983Date of Patent: March 19, 1985Assignee: Rieter Machine Works LimitedInventor: Urs Staehli

Patent number: 4454631Abstract: An emergency actuator bar extends across an opening in the housing of a lint cleaner in a cotton gin. Actuator arms which hold the bar also normally hold a trip plate in the run position. However, a workman striking the emergency bar will remove a sear on one of the actuator arms from the trip plate to permit a spring to snap the trip plate into a stop position. When the trip plate moves to the stop position, it disconnects electrical power to a motor driving the machine. The trip plate movement also applies a brake which stops the machine.Type: GrantFiled: May 18, 1983Date of Patent: June 19, 1984Assignee: Horn and Gladden Lint Cleaner Co., Inc.Inventor: Robert C.
