  • Patent number: 4625365
    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.

  • Patent number: 4463479
    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.

  • Patent number: 4019225
    Abstract: Fibers enter a textile mill at bale breaking equipment where fibers are distributed onto an open conveyor, and possibly blended, for transmittal to processing machinery such as opening and cleaning equipment, picker equipment for forming a lap, carding equipment, and drawing, roving and spinning equipment. The fibers are carried on the open conveyor past a spray station including at least one nozzle for spraying a finely diffused liquid onto the surface of the fiber material carried on the conveyor. The liquid is an aqueous solution which consists of about 75% water and about 121/2% of animal or vegetable fats as an active compound which is converted ionic salt by reaction of the organic acids contained in the animal and vegetable fats with an amine and subsequently with an alkyl sulfate. After passing the spray station, the fiber material may be transmitted through pneumatic conveyor systems to the additional processing equipment which ultimately converts the fibers into yarn or thread.

  • Patent number: 4000536
    Abstract: A self-propelled machine includes a main housing supported on front and rear drive rollers and has an operator control handle extending from the rear. Front and rear elongated working brushes are driven in orbital movement in horizontal planes, with the front brush being positioned ahead of the front roller and the rear brush position behind the rear roller. A pressurized supply tank for the working solution includes agitating and aerating means for creating a foam, and includes an adjustable control gate for controlling the flow of foam through dispensing passages to the floor surfaces ahead of the front brush. The drive rollers act as squeegees. A collection system includes vacuum pickup nozzles adjacent each of the drive rollers for picking up material from the floor surface, which material is collected in a collection tank.
