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.

Abstract: A workpiece transfer mechanism including a base having spaced parallel slides mounted in spaced parallel ways, bellcrank levers having their central portions pivotally mounted on the slides and having first portions pivotally mounting workpiece engaging members and having second portions connected by tie rods, with the force required to overcome the frictional engagement between the slides and the ways being greater than the force required to pivot the bellcrank levers, whereby the application of a unidirectional force to the tie rods will cause the workpiece engaging members to engage the workpiece prior to the time that the unidirectional force will cause the slides to move in the ways to transfer the workpiece from one position to another.

Abstract: A feeding arrangement for transporting material or work-pieces, with a pair of gripper bars moveable back and forth in the feed direction. The gripper bars extend along the transport path, and are moveable separately from one another, in the vertical direction and transversely to the feed direction. A cam drive has three cams on a common shaft, with each cam used for generating the gripper bar motions in one predetermined direction, particularly for transporting workpieces in presses with several fabricating stations following one another in the feed direction. A lifting frame having a cam follower operating in conjunction with a cam to generate vertical motions, is in contact with the gripper bars running in lengthwise guides and in cross rails on the lifting frame.

Abstract: A beam-type transfer mechanism for moving workpieces step by step along a row of stations. A pair of laterally spaced beams extend parallel to the row of stations, having opposed work holding fixtures cooperable to grip the workpieces. The beams are movable laterally toward and away from each other, vertically up and down and longitudinally in forward and rearward directions to simultaneously advance the workpieces one step at a time from station to station.

Abstract: A transfer device for progressively indexing workpieces between stations in a die mounted in a press. The transfer device, or transfer mechanism, is positioned along side the press bed. A work-gripping fingerbar is supported for transverse movement on a carriage which is slidably movable lengthwise of the press. The fingerbar moves in a rectangularly-shaped path derived from the combined shifting of the fingerbar on the carriage and shifting of the carriage lengthwise of the press. An axially shiftable rod extends lengthwise through the carriage and is axially reciprocated to produce the described motion of the fingerbar. The fingerbar is transversely shifted by a cam follower on the rod which engages a helical cam groove in a sleeve journalled within the carriage to rotate the sleeve as the rod is shifted relative to the carriage. Means which operatively connect the sleeve to the fingerbar for shifting the latter includes a yieldable coupling. A positive safety retract mechanism is also operatively connected to the fingerbar and is operative independently of the rod. The safety retract mechanism is positioned to be operated by the descending press ram should the usual drive arrangement fail to retract the fingerbar from between the closing halves of the die. The safety retract mechanism rotates a shaft which breaks the yieldable coupling to retract the fingerbar.

Abstract: A mechanism for transferring workpieces along a succession of equidistantly spaced work stations. The mechanism comprises a plurality of workpiece-engaging members carried by one or more bars, together with actuating means for moving the bars in a rectangular path to engage, transfer, and disengage the workpieces, and retract to their original positions. The actuating means comprises a reciprocable actuator which may be linked with the motion of a press, link and bell crank means connecting the actuator to the bars, and cam and cam follower means connected to the bell crank to create rectilinear motion of the work-engaging bars in response to the reciprocating motion of the actuator.
