Abstract

328,674. Mallett, S. G. Jan. 30, 1929. Metal-sheet feeds.-A device for guiding a metal strip c so as to centre it with respect to punching dies a' comprises bell crank levers d' connected by a link d<4> and pressed inwardly by an adjustable spring f, the longer arms of the bell cranks carrying rollers e or pivoted shoes for pressing against the edge of the strip. The lever pivots are adjustable and are carried by a plate b which may be mounted above the strip. The levers are provided with flared ends to enable the strip to be entered, and with projections d<5> which engage fixed stops when no work is in position. The spring connection between the levers may consist of a pair of springs whose helices are interengaged and position by a central rod f<1>. The levers d<1> may be directly connected by a pin and slot or by any connection which ensures that both levers move together, but in opposite directions.
