Abstract: An improved gin saw stand for ginning seed cotton or reginning cotton seed is disclosed. The gin stand of this invention includes an inlet in the roll box allowing seed cotton or seed to be fed directly therein without the need for a huller front or its associated picker roller and huller ribs. A power driven paddle roller having a plurality of outwardly extending elongated paddles rotating in the opposite direction from the first gin saw cylinder is also placed within this roll box. The elongated paddles of this paddle roller are effective for independently turning the seed cotton and/or seeds accumulated in the roll box, consequently bringing them into contact with the gin saw cylinder where the lint may be gripped by the teeth of the saw. To control the rate of seed passage between the blades of the gin saw cylinder and their subsequent discharge from the gin stand, a power driven, seed metering roller is positioned adjacent to the saw cylinder and on the same side thereof as the ginning ribs.

Abstract: A gin stand heat detection apparatus which includes a pair of infrared thermocouples typically mounted on the main frame weldment of a gin assembly in facing relationship beside the saw cylinder assembly and the doffing roller, for monitoring the temperature of the saw blades and ginning ribs in the saw cylinder assembly. The infrared thermocouples are electrically connected to a control panel, which control panel is, in turn, typically connected to a conventional gin stand control panel. The infrared thermocouple control panel includes a visual alarm system for notifying an operator that a high temperature condition exists at any point along the saw blades and interspaced ginning ribs between the facing infrared thermocouples. The apparatus is also capable of automatically separating the saw blades and ginning ribs in case of a high temperature event.

Abstract: 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.

Abstract: Seed cotton is cleaned in a cotton gin by wiping it over grid bars having a large gap between them. In this manner more cotton per hour may be cleaned. Excessive seed cotton falling through the grid bars with the trash is reclaimed by saw cylinder reclaimers. The cotton with the least amount of trash has the trash from a preliminary reclaimer going to the saw cylinder receiving cotton with more trash. The seed cotton which has been reclaimed may be further cleaned by wiping it across a grid bar and thereafter reclaiming any cotton which might go through the grid bars of the reclamation wiper cleaner. By-passes are provided to by-pass the cleaner cotton that passes through grid bars into the main stream of cleaned cotton. Also, the cotton which is first reclaimed can be passed into the stream of clean cotton without further cleaning.

Abstract: A method of delinting cotton seed comprises the steps of passing the cotton seed through a saw delinter to remove a substantial portion of the lint, preferably at least 40%, therefrom, and thereafter passing the partially delinted seed through a brush delinter to remove substantially all of the remaining lint therefrom.In a preferred embodiment of the invention, the seed is passed through two saw delinting stages to remove more than about 40% in the first stage and up to about 20% or more in the second stage, whereby more than about 60% of the lint is removed in the two saw delinting stages. Subsequent passage of the seed through a brush delinter removes additional lint so that up to 97% of the lint is removed in the combination of the saw delinting and brush delinting steps. An optional further step of passing the seed through a flamer can be used to remove the remaining approximately 3% of the lint.

Abstract: A roller for the treatment of fiber masses for the textile industry has a sawtooth wire received in a rectangular cross section helical groove of a steel roll body and indented by a peening or indenting roller to provide, by plastic deformation of the foot portion, the outward forces which clamp the foot portion of the wire against the ribs flanking the groove of the roller body. As a consequence, the roller body as a whole is not deformed.

Abstract: Differential ginning is achieved by modifications to conventional saw-type ginning including, providing a saw gang including at least two saw sections each including at least one saw blade, conveying of material to be ginned (e.g. seed cotton) successively to each section, ginning of the material in each section so as to separate a portion of lint from the material, and separate removal of lint from each section. Thereby producing portions of lint, wherein the fiber qualities vary from portion to portion e.g. separating longer fibers from shorter fibers.

Abstract: A ginning point assembly for use in conjunction with a cotton gin rib comprising a rectangular mounting plate for removable attachment to rib, first and second opposed recesses formed in plate, a roller mounted in each of recesses for rotation at ginning point in a direction transverse to the longitudinal axis of rib to which the plate is attached, and a shield attached to said mounting plate above said rollers to prevent said debris or cotton from interfering with the rotation of the rollers.

Abstract: A cotton gin bar including a roller assembly comprising a pair of discs rotatably arranged on the upper portion of the bar at the ginning point, the discs being operative on opposing sides of the bar for detaching lint from the seed. Each roller disc is provided with an annular rib and the gin bar is provided with an annular groove in which the rib is received, thereby defining a rotatable seal. The rotatable seal restricts the passage of small particles such as grit and lint which interfere with operation of the annular bearing on which the roller disc is mounted.

Abstract: A method for training a gin saw assembly and a ginning rib assembly that have been removed from a cotton gin includes a telescoping stand on which the gin saw assembly, including its bearings is temporarily mounted. The apparatus includes an adjustable template with alignment marks with which the individual gin saw blades are manually aligned. The apparatus also includes mounting elements by means of which the ginning rib assembly can be mounted adjacent to the gin saw assembly after the gin saw blades have been trained. The telescoping stand is then extended so that the gin saw blades extend into narrow gaps between the individual ginning ribs in substantially the same relation thereto as when the gin saw assembly and ginning rib assembly are operating in the cotton gin. The individual ribs are then adjusted so that the gin saw blades are precisely centrally positioned in the gaps.
