depicted in its normal position, is in anidlemode. the con-. stantly'rotating' camshaft 42 rotates the drive cam 34 clockwise; and the link 37 isdriven upward, as the high point 33 of the drive cam 34 approaches the uppermost point of its travel; exerting an upward force on the lever 22 pivotally'connected thereto. The lever 22 is restrained at one end 30 by'the coil spring 23, but the other end 32 is free and moves' upward, pivoting about the first fulcrum 15. After the high point 33 of the drive cam 34 passes the uppermost point of its travel, the

lever 22 is lowered to its normal-position. I

In a punch mode, the power means 28 is activated, retracting the latch 48. With the latch 48 retracted. the bellcrank 19 will be pivoted toward the end 32 of the lever 22 by the coil spring 29, thus moving the fulcrum 21 into effective position over the end 32 of the lever 22.

The constantly rotating camshaft 42 rotates the drive cam 34 clockwise; and the link 37 is driven upward, as the high point 33 of the drive cam 34- approaches the uppermost point of its travel, exerting an upward force on the lever 22 pivotally connected thereto. The lever is restrained at one end 32 by the retractable fulcrum 21. The other end is forced upward against the bias of the coil spring 23. carrying the punch 2 into agreement with the punch die -67 as the high point 33 of the drive cam 34 reaches the uppermost point of its travel. After the high point 33 of the drive (31111134 passes the uppermost point of its travel, the lever 22 is lowered to its normal position.

The constantly rotating camshaft 42. also rotates the reset cam 44 clockwise. The high point of this cam 44 lags the high point 33 of the drive cam 3-2 such that it reaches its uppermost point of travel after the high point 33 ofthc drive cam 34 has passed its uppermost point of travel. The action of the reset cam 44 pivots the tripedal lever 25 clockwise, causing the bellcrank reset stud 31 to pivot the bellcrank '19 clockwise, thus retracting the fulcrum 21 from its effective position relative to the end 32 of the lever 22. The arm 39 of the tripedal lever 25 also supplements the action of the coil spring 46 in restoring the latch 48 to its normal position. By the time the high point 33 of the drive cam 34 reaches its lowermost point of travel, the high point 43 of the reset cam 44 has passed its effective position with respect to the tripedal lever 25; and the bellcrank i9 is once again in its normal position, held away from the end 32 ofthc lever 22 by the retractable latch 48.

The function of the shackle 36 is to restrict the motion imparted to the lever 22 by the drive cam 3-3 at the pivotal point of connection of the link 37 to the lever 22 such that this point effectively reciprocates vertically.

With reference to FIGS. 3 and assuming the mechanism, depicted in its normal position, is in an idle mode. the con stantly rotating camshaft 98 rotates the drive cam 51 clockwise; and the link 57 is driven upward, as the high point of the drive cam 51 approaches the uppermost point of its travel, exerting an upward force on the second lever 72 pivotally connected thereto. The second lever 72 is restrained at one end by the weight of the first lever 64 pivotally connected thereto, but the other end 63 is free and moves up ward. Aftcr the high point 55 of the drive cam 51 passes the uppermost point of its travel, the second lever 72 is lowered to its normal position.

In a sensing mod, the power means 80 is activated, retracting the latch 90. With the latch 94) retracted, the bellcrank 88 will be pivoted toward the end 63 ofthe second lever 72 by the coil spring 94, thus moving the fulcrum 89 into effective position over the end 63 of the second lever '72.

The constantly rotating camshaft 58 rotates the drive cam 51 clockwise; and the link 57 is driven upward, as the high point 55 of the drive cam 51 approaches the uppermost point of its travel, exerting an upward force on the second lever 7.2 pivotally connected thereto. The second lever 7.2 is restrained at one end 63 by the retractable fulcrum iii". The other end 7 is forced upward, exerting an upward force on the first lever 6-4 pivotally connected thereto.

The first lever is restrained at one end 61 by the coil spring 32. The other end 59 is free and moves upward, providing the record medium in the processing station 50 contains a code hole, pivoting about the second fulcrum 66 and carrying the sensing pin 56 into agreement with the perforation 71 in the backup 6) as the high point 55 ofthe drive cam 51 reaches the uppermost point of its travel. After the high point 55 of the drive cam 51 passes the uppermost point of its travel, the first 64 and second 72 levers are lowered to their normal positions.

If the record medium in the processing station 50 does not contain a code hole, the sensing pin 56 will be prevented from moving upward: and the other end 61 of the first lever 64 will be forced upward against the bias ofthe coil spring 82, and thc movably yicldable second fulcrum 66 activating the control means 68 as the high point 55 of the drive cam 51 reaches the uppermost point of its travel. After the high point 55 of the drive cam 51 passes the uppermost point of its travel, the first 6% and second 72 levers are lowered to their normal positions.

The constantly rotating cam shaft 98 also rotates the reset cam 96 clockwise. The high point 95 of this cam 96 lags the high point 55 of the drive cam 51 such that it reaches its uppermost point oftravel after the high point 55 ofthe drive cam 51 has passed its uppermost point of travel. The action of the reset cam'96 pivots the tripedal lever 92 clockwise, causing the bellcrank reset stud 83 to pivot the bellcrank 88 clockwise. thus retracting the fulcrum 89 from its effective position relative to the end 63 of the second lever 72. The arm 91 of the tripedal lever 92 also supplements the action of the coil spring 87 in restoring the latch to its normal position. By the time the high point 55 of the drive cam 51 reaches its lowermost point of travel, the high point 95 of the reset cam 96 has passed its effective position with respect to the tripedal lever 92; and the bellcranl; 88 is once again in its normal position. held away from the end 63 of the second lever 72 by the retractable latch 90.

The function of the shackle 86 is to restrict the motion imparted to the second lever 72 by the drive cam 51 at the pivotal point of connection of the link 57 to the second lever 72 such that this point effectively reciprocates vertically.
