To effect a movement ofthe heel I gage radially. of the block, the shaft 120 is rotated'by means of the pin-'and-slot con struction illustrated in Figs. 6 and 7 A plunger122 is adapted to slide within the shaft' 12Q but is normallylocked against 1e; tative" movement by meansof a pin 124*ex tending through 'a'noblique slot126 of the shaft and contacting with the Walls of a 1011-- gitndinal slot" 128 in the collar 130 which is mounted onthejshaft 120. Consequently, longitudinal movement ofthe plunger-122 and pin 1243vvillcause rotation of the shaft 120 andm ovement" of gage'28 by reason of the contact ofthe pin with the Walls of theoblique' slot 126.

Movement of the screw 131 eife'cts a row tation of the sleeve 114 to adjust the gage '1 towardor awav from the surface of th'e block. To provide for convenientad ustment of i the heel gageizs to various lengths of blanks,
afle'v er (132 is arranged for" actuating the V plunger 122 by means of a rock-shaft13t a forked member'- 136yengaging a' grooved collar 138ontheendof theIplLmger.

i it isnecessary that'thef gages 26 and the heel gage 28 beretract'ed from engagement vvith the "blank 1011 11116 die" block 225'early in he 'jflhe mechanism for retracting the ga'ge 28 originaljposition;
of the arm 152. Rotation of the collar 130 in-ia clockwise direction causes a similarrotation ofthe 124,: and since longitudinal movement of the plunger 122 is prevented by the latch device 14:O142,' the shaft 120 is rotated to retract the gage 28. As rotation of the'collar 130 continues, a pin 154 on a bell-crank 156Will be engaged in a recess 15 8 in the, flange of the collar130 causing rotation of the bell-crank'156. Sincethe latter is secured to the sleeve 114 by means of the bolt 160, rotation" of the hell-crank causes rotation of the sleeve" 114, and gage 28 is'rotated' awa yfrom theusurface of the die block! The gage is held "in it's rotated position during "the dieing-out operation by means of'a spring latch "162 Whichfengages a lug 164' on the bell-crank 156. a After an operationof the die, the roll 146 reaches the low portion 166 of the cam l l lsand a spring 168depresses the link150 causing rotation of the collar 130in' a counter 'clockwisedirectionwith theresult that the gage 28 isextended nearly itswholelengthout of its supporting member 112. Upon further: depression thexlink 150 contactswithsa plate 170 at 'tached to the latch 162, tripping thelatch and permitting a spring 172m rotate the bell-crank1156 which causes rotationiof vth'e [sleeve lltand of the gage28', Whileinits ex tended position,back towardvthe*dieblock;
On'stillfurther rotation ofthe cam 14 4:, the
