  • Patent number: 4096731
    Abstract: A method and apparatus is provided for transferring articles between successive work stations at which working operations are effected. More particularly, the workpieces are transferred between the forming stations on a multistage forming press. On completion of a machining operation, a burst of the coolant/lubricant emulsion used in the forming press is fired at the workpiece from a propelling nozzle located near the forming station. The workpiece is thus propelled to the next station along a curved guideway which comprises a smooth, curved track bounded by guiderails. On arrival at the next station, the workpiece is guided into position by guide members and finally positioned exactly by means of a burst of the same coolant/lubricant emulsion fired from a positioning nozzle located near the station. Regulating mechanisms are provided to fire bursts of emulsion in time with the working stroke of the press.

  • Patent number: 4095707
    Abstract: A transfer mechanism for dumping the contents of a shipping drum into an open-topped mixing vessel has a rotatable frame spaced above the support surface on which the vessel and drum can be rolled about, the frame having an annular plate and hooks on one side of the plate for lifting and holding the vessel against that side of the plate and a fork on the opposite side of the plate for lifting and holding a drum against that opposite side of the plate. By first picking up the vessel, rotating the frame 180.degree. to turn the vessel upside down, picking up the drum, and rotating the frame to its original position with the drum upside down, the drum contents are transferred to the vessel through the annular plate in a confined manner. A suction chamber is mounted on the transfer mechanism to withdraw any remaining loose material or dust from the shipping drum before it is removed from the transfer mechanism.

  • Patent number: 4095752
    Abstract: A motorized shovel comprises a carriage which may be provided with wheels to enable it to negotiate the ground and is formed with an upright pole carrying an arm adapted to overhang the operator. The arm is swingable about a vertical axis to follow the movements of an operator and carries a pneumatic-motor-driven winch drum adapted to pay out and retract a cable depending from the free end of the arm. The cable is anchored to a shovel unit whose handle is provided with a handle bar adapted to be gripped by the operator. Controls on the handle bar regulate the operation of the winch and of a pneumatic vibrator interposed between the handle and the shovel blade. Flexible conduits run along the downwardly extending stretch of the cable to connect the pneumatic controls to the winch.

  • Patent number: 4094254
    Abstract: A lock for a railway hopper car gate in which a hopper outlet chute defines a discharge opening with a siding platelike gate operating in the opening. An undercarriage structure having a pair of spaced side frames supports the gate for sliding movement relative the opening. An elongated lock shaft extends between and projects through guide slots formed in both side frames with one of the side frames also being formed with a lock hole. A U-shaped handle is fixed to each end of the lock shaft with each handle having a return leg supported for transverse and pivoting movement relative the side frames. A latching shoulder is fixed to the elongated lock shaft and one of the guide slots is formed with a latching notch. Transverse movement of the lock shaft by operation of either handle effects an engagement of one of the handle return legs into the frame hole to thereby lock the gate.
