Abstract: A transfer apparatus designed so that workpiece transfer pins are fixed at predetermined intervals to a chain circulating along a frame. The pins horizontally project through a lateral surface of the frame and are also circulated in conjunction with the circulation of the chain so that apertured workpieces may be caught by the pins projecting through the frame and be conveyed along with the travel of the pins. Along the path of travel of the pins and at the necessary locations, there are disposed workpiece inlet, outlet, bypass and delivery devices. Other merits and details of the construction will be made clear.
Abstract: An apparatus is disclosed wherein annular articles conveyed one by one to a chute member are successively transferred to a rail member connected to the chute member until a predetermined number of articles are lined up thereon, whereupon a plurality of slender holders waiting their turn above the individual articles are lowered and then lifted in unison, whereby the holders pass through the apertures of the articles in their downward travel and in their upward travel they lift the articles in unison which are held in position as a result of projectable members installed at the front ends of the holders being projected in connection with the upward movement of the holders, the above operation being repeatedly carried out a plurality of times until each holder is loaded with a desired number of articles piled in a stack, the stacks of articles on the individual holders being then released in unison onto a table member, the latter being adapted to be inched each time it receives the stacks so that such articles
Abstract: There is disclosed a bobbin hanger comprising an upper assembly serving for attachment and aligning suspension, an intermediate assembly serving for constrained rotation and alignment, and a lower assembly serving for removable mounting and aligning suspension of a bobbin. Below the upper assembly, the intermediate assembly is suspended through a pivot having enlarged head portions at both ends thereof, and a dust-proof filter is incorporated between the upper and intermediate assemblies for prevention of entry of fly and dust.
