Abstract: A machine for cutting damaged ends off of rolls of wound sheet material includes a saw that moves in a circular motion about the circumference of one end of the roll of material. The circular motion of the saw is coupled with a movement of the saw radially inward toward the center of the axis of the circular movement. The roll is thereby cut in ever increasing depths about its circumference. The machine is mounted on a portable hydraulic lift and controlled by a remote controller positioned a safe distance away from the saw. The machine and the roll of material can be more easily aligned through the use of an alignment track.

Abstract: An underwater treadmill device is provided and includes a drive roller and an idler roller engaging opposite ends of a treadmill belt. A hydraulic motor is directly coupled to the drive roller for imparting rotary motion to the drive roller and the treadmill belt. The hydraulic motor is driven by a remotely located pump and electrical motor. The electrical motor drives the pump and thereby controls the speed of the hydraulic motor. The speed of the electrical motor may be controlled by a remote control unit which transmits signals in the electromagnetic spectrum. The idler roller does not include any bearings as a substantially frictionless portion rotates about another portion.

Abstract: A material handling system includes a depalletizer comprising a tower frame and a tilt bed which extends into the tower frame and is tilted to a predetermined angle. A lift bed raises a loaded pallet to the level of an exit conveyor. A back dam is disposed opposite the exit conveyor and is movably mounted to the frame to exert a stop against a layer of articles to be removed. An endless collector belt is mounted to the tower frame and simultaneously rotates and moves between a position adjacent the exit conveyor and a position adjacent the back dam to remove the entire layer of articles.

Abstract: A roller conveyor is provided with a rotating turning wheel disposed along one side of the conveyor and engaging and turning products as the products are moved along the conveyor. The rotating wheel is provided with a conically-shaped upper surface having a lower edged disposed below the level of the plane of the conveyor. An adjustable guide bar directs products to an area of the wheel displaced from the outer edge of the wheel by a selected distance. As the product engages the wheel, a portion of the product is raised to facilitate turning of the product and a force extending in the direction of travel is applied to the product in the area of contact with the wheel. The wheel is mounted on a vertically extending shaft further having a drive disc mounted thereon. A drive wheel mounted on a horizontally extending shaft rotates the drive disc. A pulley mounted on the horizontal shaft is driven by the conveyor roller drive belt.

Abstract: A pneumatically actuated lubricant pump wherein air is forced into the cylinder through a passage extending longitudinally through the piston rod. The rod is part of a piston assembly reciprocably mounted within a pump housing. The air passage extends from a lateral rod entrance through the rod and through the piston head. Air is forced into and released from the air cylinder through the passageway. In an alternative double-action embodiment, a second air flow passage extends through the pump housing alone directly to the air cylinder permitting compressed air to be alternately supplied to the opposite sides of the piston head.

Abstract: A conveyor comprises parallel side frames provided with a plurality of apertures and C-shaped cross members provided with apertures in the side walls disposed in juxtaposition to apertures in the side frames. The cross member apertures are each defined by a flat inner wall. The cross members are fastened to the side frames by means of hook-bolts having a hook portion extending through the side wall apertures and a shaft extending to a juxtaposed aperture in the side frame and provided with a nut and washer to secure the bolt in the side frame. The hook portion of the bolt is provided with a flat surface extending a substantial distance across the inner surface of the hook portion of the bolt to provide a load bearing contact area with the inner wall of the side member aperture. The cross members have tabs extending outwardly from each end which are inserted into complementary apertures in the side frames. The resulting bolted conveyor frame construction ensures frame alignment under heavy loads.

Abstract: A roller conveyor for aligning and separating material placed on the conveyor comprises a frame having side walls connected by crossmembers and a plurality of rollers mounted between the side walls. The frame further comprises a pair of supplemental side walls disposed between the parallel side walls to define an opening in which is disposed an aligner/separator assembly. The aligner/separator assembly comprises two frame mounted counter-rotating rollers driven by a motor. The counter-rotating rollers extend at a predetermined angle above the plane of the conveyor. The counter-rotating rollers rotate in the direction of the corresponding side wall and any unit contacting one of the rollers is laterally translated in the direction of the corresponding side wall. The counter-rotating rollers serve to separate adjacent units and to align the units with respect to the counter-rotating rollers.

A back dam is disposed opposite the exit conveyor and is movably mounted to the frame to exert a force against a layer of articles to be removed. A collector roller is mounted to the tower frame and moves between a position adjacent the exit conveyor and a position adjacent the back dam to assist in the removal of any articles remaining after the force has been applied by the back dam.

Abstract: A conveyor trolley and chain cleaner which straddles the conveyor track and drives a pair of askew mounted brushes in counter directions while urging the brushes toward resilient contact with track chain and parts moving thereon. The motor and drive means are tensioned and provide overload slippage.

Abstract: A liquid handling system for filling tanks, such as tank trucks, particularly suitable for handling volatile fluids, employing a fill conduit and an emergency shutoff valve located at the upper end of the fill conduit. The emergency valve employs an annular, normally open, valve element axially displaceable to a shutoff position upon the liquid level within the tank reaching a predetermined maximum depth. Valve element operation is regulated by a control piston subjected to subatmospheric pressures produced by liquid flow through the valve and upon the liquid level reaching a predetermined depth the control piston is actuated to cause the valve element to terminate fluid flow. The emergency shutoff valve may be employed in conjunction with a variable rate flow valve connected in series therewith to produce a versatile tank filling system.
