Abstract: 19,313. Harvey, J. B. Aug. 23. Stamp-applying.-Relates to the general construction of machines for cancelling and affixing stamps to insurance cards &c. These are placed on a table 1 and beneath an affixing- plunger 63, and the machine is operated by turning a crank-shaft 3. Duplicate cancelling and feeding devices may be arranged on each side of the plunger 63 so that stamps may be used from either of two spools 17, 140, the shaft 3 being moved axially and locked by a catch 134 to throw the requisite cams and wipers thereon into and out of operation with the cancelling and feeding devices. The following description of one set of cancelling and feeding devices serves for both sets. The stamp strip from the spool 17 is fed by rollers 35, 45 turned by friction or bevel wheels 37, 51, a shaft 49, and a friction or toothed wheel 53 turned bv a wiper 12 on the shaft 3. The lower roller 45 is adjustable by a screw 47. The stamps are cancelled by an ordinary device A adapted to be depressed against the action of a spring 61 by a cam 9 on the shaft 3. The end stamp is supported beneath the plunger 63 by rollers 82, Fig. 6, on a spring arm 78 hinged at 79<a> to the frame of the machine. When the plunger is depressed against the action of a spring 69 by a cam 7 on the shaft 3, it presses the stamp on to the rollers 82, the arm 78 being prevented from rocking by a stop 75 carried by a vertical slide 70. A piston 66 on a hollow rod 65, Fig. 9, carried by the plunger 63 slides within a cylinder 67. The stamp beneath the plunger prevents the passage of air through the aperture 66<a> and the rod 65 and a rarefaction of the air in the cylinder occurs and holds the stamp on the plunger until it is about to be affixed to the card, and the piston 66 then passes beneath holes 68 in the cylinder and air enters and releases the stamp. Meanwhile, a cam 8 on the shaft 3 allows a spring 76 to raise the slide 70 and the stop 75. The arm 78 is rocked against the action of a spring by the plunger 63 and a wet roller 80 carried by the arm damps the stamp, and one of two cutters 77 carried by the slide 70 severs the end stamp. While the stamp is being affixed, the card is supported by bars 112, 113 to which tapes 110, 111 are secured. These are wound around drums 101, 102 adapted to be turned by springs 109 connected to pulleys 96, 97. Tapes 93, 94 are wound around these pulleys at one end and are attached at the other end to rods 85, 86. Cams 10, 5 on the shaft 3 raise these rods and wind-up the springs 109, the drums 101, 102 being prevented from rotating by triggers 105 engaging stops 169 on them. When a card has been stamped, stops 103, 104 on the tapes 93, 94 rock the triggers 105 and release the drums 101, 102; the springs 109 then draw the bars 112, 113 apart against the action of a spring 126 and allow the stamped card to fall into a receptacle. The cards are positioned week-byweek by being placed in a frame 127 adjustable transversely by screws 128 and slots 129 in a frame 130 which is adjustable longitudinally on the table 1 by screws 132 and slots 131. According to a modification, the cards may be fed through the machine by rollers 150, 156, Fig. 10, rotated by a pulley 148 turned by a belt 149 and a pulley 143 turned by a crank 141 on the shaft 3 engaging radial ribs 142 on it. The cards are placed in a flexible band 168, Fig. 13, which is then folded as shown and placed on a plate 167 integral with a guide 162, Figs. 10 and 13. The rollers 150, 156 feed the band and the cards contained therein intermittently through the machine. The guide 162 is adjustable on the table 1 by screws 161, 166, and slots in a manner similar to that of the frame 127, Fig. 2.
