The shifting of the jackets and weights from the molds on one conveyor system run to a contiguous conveyor system run is performed automatically by a swinging boom mechanism having a vertical lift mechanism on the outer end of the boom. An open clamp means attached to the lower end of the lift rod closes the clamp on the jacket and accompanying weight of a mold in which the molten metal has solidified. The closed clamp and its load is lifted clear of the mold, swung on the supporting post through an angle to an aligned position over a fresh mold approaching the metal pouring station, after which the jacket and weight, held in the clamp assembly, is lowered over the green mold, set or snugged down on the mold, and the clamp is then opened, raised, swung back over the first conveyor run, and the cycle repeated. The operation is synchronous with the step-by-step movement of the mold pallets on the conveyor.
An automatic handling machine for transferring objects, for example vehicle windows, from one location to another comprises a horizontal arm pivotally mounted at one end for movement about a vertical axis. The other end of the arm is provided with means, such as a suction cup, for gripping the objects. The pivotal mounting for the arm includes a slide which is translatable in a horizontal direction. A connecting rod is linked to the arm at a point intermediate the ends of the arm and is adapted to turn in a horizontal plane about a fixed axis.
An inner surface honing device for use in a honing machine which comprises a centrally bored work table rotatably provided on a main body, a work piece exchange table disposed in a position opposite to the work table, a main shaft having honing stones which extends into the work table from the lower part of the latter, and an rotatory arm disposed between the work table and the exchange table for clamping a work piece at one end while another work piece is honed at the other end. The work piece already honed is transferred onto the exchange table for removal while the work piece to be honed is positioned on the work table by mere rotation of the rotatory arm for efficient honing operation.
The apparatus defines at least two work stations, at one of which is disposed an abrading machine having an operating surface, and between which carrier means is reciprocally movable. Power actuated means on the carrier means selectively serves to raise and lower at least one work piece, to transfer the work piece from one work station to the other, and to forcibly urge the work piece against the operating surface.
Lifting apparatus which enables the lid of, for example a coke oven, to be removed during charging and then replaced has engagement means for the lid carried at the end of an arm. The arm is able to be raised and lowered and to be swung through an arc. The engagement means hook onto the lid or other object to be removed or replaced and the engagement means can oscillate at the end of the arm.
A rotating device for rotatably transferring yarn skeins or hanks from a first generally stationary support or carrier to a second generally movable support or carrier, the latter being substantially at the same level as the first support or carrier, comprises a vertical structure, carrying two slide guides parallel to the movement of the second support; thereon a carriage having a rotating head is movable and has a rotating frame with two slide bars integral therewith; a rod carrying slider moves forwardly and backwardly on the bars, and carries two skein-holder rods which are parallel to each other and can be moved toward and away from each other. Preferably, the rotational movement is given by a cylinder-piston assembly between the vertical structure and an eccentric location on the rotating frame.
