Electric connection mfr. machine - uses hydraulic or pneumatic piston to drive combs of contacts into multiple connection block for telephone circuits

摘要

The contact manufacturing machine includes a base (1) supporting an upright column (2). A horizontal plate (3) attached to the column holds a bar arranged to slide vertically. The lower end of the bar has a fitting to hold a contact carrying block. The bar has a toothed rack which engages a toothed wheel (7) whose spindle is rigidly attached to an operating lever (8). Above the plate is an hydraulic or pneumatic jack (9) coaxial with the bar for operating it. A horizontal carriage (12) sliding on rails (13) supports the board into which the contact carriers are to be fitted. The contacts themselves are cylindrical with two sections. A first small diameter section locates the contact when it is inserted while the second wider part provides a frictional grip.
