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, mounted to the tower frame, extends over a slidable frame provided with a polygon shaped roller. The endless belt 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 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 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 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 load supporting conveyor having live rollers forming a load conveying path in which the rollers are driven by a chain having horizontally placed links and vertically positioned rollers with vertical axles that project upwardly toward the live rollers to be engaged by a flexible pad substantially aligned with the drive chain and an aperture pattern formed in the pad to establish a series of apertures that have a tight fit with certain ones of the vertical axle projections and a series of other apertures that have a loose fit with a like series of vertical axle projections.

Abstract: The invention herein is concerned with not only limiting the velocity of packages on a downwardly inclined conveyor trackway, but effecting a cyclically operable system of brake assemblies that not only brake the flow of packages down the trackway but effect reversal of groups of rollers in the trackway for short periods of time so that gaps are created between packages as they accumulate at the end of the trackway so that the pressure between packages is redudced so as not to damage the contents. The brake assemblies are distributed in adjacent series along the trackway and operate in association with different groups of rollers and in timed cycles so that packages are prevented from developing a free or unretarded flow under gravity influence.

Abstract: An endless chain having a tension and a relaxed non-tension run, and a lubricant delivery control including friction responsive elements to sense the friction condition between the chain and a part of a supporting track and respond on increasing friction to dispense lubricant into the non-tension chain run which is carried to the friction sensing element to eventually reduce the friction and allow the sensor to cut-off lubricant supply.

Abstract: A roller conveyor having a series of rollers forming a main path of travel for articles, a second series of rollers branching from the main series of rollers and forming a branch path of movement, mechanisms at the junction of the first and second series of rollers for selectively diverting articles to the second series of rollers in a predetermined manner, a flexible drive member having roller engaging passes for both the first and second series of rollers and idle passes out of roller engagement for simultaneously driving the first and second series of article supporting rollers, and a drive for said flexible means for effecting the simultaneous operation of the first and second series of rollers.

Abstract: This invention relates to a threaded pinch-bolt sleeve which is utilized in conjunction with an associated retaining nut to hold a replacement shock absorber within the cylindrical housing of a vehicular suspension system of the type commonly referred to as a MacPherson strut suspension system. The sleeve includes a generally cylindrical main body portion which is placed over the upper portion of the cylindrical housing. A pinch bolt attached to the outer side wall of the main body portion is tightened to secure the sleeve to the cylinder. The upper end of the sleeve is provided with either internal or external threads to receive a retaining nut to hold the replacement shock absorber in the associated cylindrical housing.

Abstract: A conveying device for transferring articles, such as pallets, between a first conveyor running in one direction and at one level and a second conveyor running in a right angular direction to the first conveyor and at a different level, wherein the article transfer is accomplished by a power operated mechanism which not only controls the movement of the article between the conveyors but also accomplishes the change in levels between the conveyors.

Abstract: Conveying apparatus having primary support means of low friction character such as roller means or low friction slide or runner means to carry the weight of articles to be moved from place to place, and endless drag means propelled along the primary support and provided with motion exciting means adapted to engage and propel the articles. When the articles are to be accumulated a stop is imposed on the lead articles and thereafter the exciter means propels successive articles into the accumulation area and in each instance the exciter means passes underneath the articles to follow the path of the endless drag means. The exciter means is constructed to be easily replaced as it is the principal part that takes wear, and the degree of frictional contact with the articles may be selected to match the weight of the articles so as to require the least power and generate the least accumulative pressure.
