Abstract: A feeder mechanism for feeding a sheet of metal to be blanked in a zigzag fashion in cooperation with a sheet of metal feeder mechanism of a press. A reversible D.C. motor is employed for reciprocating the sheet of metal in a direction at right angles to the sheet of metal feed direction of the press. The forward and reverse rotation and its cycle of the D.C. motor are controlled by a controller in synchronism with the feeding speed of the sheet of metal. The rotational motion of the D.C. motor is translated into a linear reciprocating motion of a die set by a rack and pinion mechanism. The rack is connected to the die set and is reciprocated in a direction at right angles to the sheet of metal feed direction of the press.

Abstract: An apparatus for manually shifting a transfer bar of a transfer press between a first or advanced position and a second or retreated position. The apparatus is mounted on a moving bolster and comprises a frame and a sliding member slidable between the first and second positions and carrying a transfer bar thereon. A lever is pivotally mounted at its base end to the frame and the leading end of the lever has a roller rotatably mounted thereto. The roller is adapted to move vertically guided by a guide member mounted to the under surface of the sliding member as the lever pivots on its base end. A spring is provided for helping the movements of the transfer bar between the first and second positions.

Abstract: A transfer press is disclosed including a bed, at least two slides, uprights and a crown. Driving means for the slides are accommodated within a plurality of driving chambers. Connecting rods are inserted within said uprights for tightly connecting said driving chambers with said bed. Each slide is actuated by a pair of connecting rods positioned diagonally adjacent to both ends thereof between forward and rearward members of the uprights for achieving uniform distribution of urging forces.

Abstract: The device for adjusting the lateral distance between a pair of parallel transfer bars of a transfer feeder for a transfer press comprises clutch means arranged in the driving means for driving toward and away a pair of slides slidably mounting thereon the transfer bars, respectively, so as to transfer work pieces to the succeeding working positions and separate driving means for driving the slides independently of the first mentioned driving means when the latter is disabled by the clutch means, so that the lateral distance is adjusted by driving the slides by the separate driving means while the first mentioned driving means is disabled. After disabling the separate driving means and the clutch means is engaged, the press is ready for operation with the newly adjusted lateral distance set between the slides and, hence, between the transfer bars. A set of limit switches are provided which cooperate with the driven member of the clutch means and operably connected to switching means of the clutch means and a clutch for the separate driving means so that the lateral distance between the slides can be automatically set by the actuation of the selected one of the limit switches which, when actuated by the driven member of the clutch means, actuates the switching means so as to engage the first mentioned clutch means while the clutch for the separate driving means is disabled after the clutch means has been disengaged and the slides have been driven by the separate driving means through the clutch.
