Abstract: 627,415. Selective embossing machines. REMINGTON RAND, Inc. Feb. 19, 1947, No. 4872. Convention date, March 7, 1946. [Class 100 (iv)] An embossing machine comprises means for feeding and serving perforated record cards, a number of pairs of co-operating dies mounted in rows in differentially settable members movable into a stamping position under the control of a record card, and an operating device for actuating all the selected pairs of dies in the stamping position. The machine comprises a hopper 28, Fig. 1, from which record cards are fed into a sensing pin box 21 reciprocated from a main shaft 18 and a translator unit 104 set by the sensing unit to displace appropriate stops 111 controlling the sliding position of a series of slides 131 to position one of a number of pairs of male and female dies 194, 195 carried by each slide 131 between an anvil 183 and a power hammer 174. The hammer is operated by a link movement 175-179, Fig. 2, from an eccentric 181-2 on a shaft 164 carrying a flywheel 165 and one revolution clutch, and driven by a motor 166. Sensing pins 23 in the box 21, Fig. 1, penetrate holes in the record card and are locked by a slide 24 actuated from the frame of the machine and thereby raise set pins 41 in a box.42 which are locked in rows by slides 46. The machine is adapted to emboss in consecutive operations the information contained in two zones of a record card in two different positions on the plate. For this purpose, a card being sensed is held stationary during two vertical movements of the box 21. The pins in each row corresponding to the upper zone are locked by one slide 46 during one vertical movement and those corresponding to the lower zone by another slide 46 during the next vertical movement. These slides have staggered end formations, Fig. 20, which are respectively engaged by paddles 53, 54 actuated by cams shaped with two diametrically opposite raised portions 57 rotated in steps of 90 degrees, the projections 57 operating paddles 53 being spaced 90 degrees from those operating the paddles 54. The shaft 51 carrying the cams is actuated from the reciprocating movement of the sensing box 21. Thus the information contained in the upper zone controls the first setting of the dies 194, 195 and that in the lower zone controls the second setting. The plate to be embossed is moved during the two settings so as to separate the two sets of information. The translator unit 104 comprises pins 107 which are engaged by the raised pins 41 and through Bowden wire connections 103, raise pins 106, which raise the corresponding stops 111 into operative positions. Each pin 106 is connected to two pins 107 corresponding to the upper and lower zones of the card. Each stop 111 corresponds to an odd number index position, and the intermediate positions are obtained by the raising of the " nine " stop in association with one of the other stops. The " nine stop can move to the right into a recess 116, Fig. 15, and permits the other stop raised also to move to set the slide 131 to the intermediate position. The stops are restored by a bail 118 operated by a lever mechanism displaced by a projection on a disc on the main shaft 18. Slides 131 move under the influence of springs 137 until a shoulder 132 engages the raised stop 111, after being released by a bail 141 reciprocated on horizontal slide rods 144 by links 146 attached to a lever 147 on shaft 148 oscillated by a lever and pitman driven round a D-shaped eccentric guideway by a lever pivoted on a disc fast on the main shaft 18. The blank plates are fed transversely from a receptacle 221 by a pair of feed blocks 226, 227 reciprocated by link mechanism 231-234 attached to a shaft 235 driven from bevel gears from the rocking shaft 148. The second embossing position of the plates is obtained by sliding the plate-carrying frame 197 on pins 199, Fig. 14, by a lever 201 operated on alternative quarter cycles of a ratchetrotated shaft 205 by a cam 206. The ratchet is rotated by a pawl and the plate reciprocated by a lever 214 connected to a lever 215 on the rocking shaft 148. During the second embossing, a trip stop 243, Fig. 7, connecting the lower feed block 227 to upper block 226, is withdrawn by a lever operated by a Bowden wire 245 connected to a lever 258 operated on alternate positions of a double striking cam on the shaft 205 so that only block 227 is advanced and no plate 196 is fed. On the next cycle, stop 243 is raised and a plate is fed, shunting the embossed plate into a collecting box 252. Specification 555,823, [Group XIX], is referred to.
