Abstract: 313,935. Cooke, A. B. Feb. 20, 1928. Autographic recorders. - In an autographic recorder in which a perforated record strip fed into a filing chamber is severed into slips which are impaled upon filing-pins, the pins are pivotally mounted and are oscillated to direct them through perforations at the forward end of the incoming slip, by controlling-means actuated by the stripfeeding mechanism. The pins enter the slip at the upper face thereof, so that the continued feeding of the slip causes it to be turned face downwardly in the filing chamber before it is severed from its strip. Three or more strips are drawn over the writing surface 2, Fig. 1, by mechanism comprising an upper roller 5 cooperating with a pair of rollers 6 mounted upon a shaft 7 provided with an operating-handle 10, Fig. 2. The rollers 6 may each consist of a pair of spaced discs 8 disposed opposite to a peripheral groove 9 in the roller 5, the distance between the grooves corresponding to the lateral distance between each pair of perforations in a slip, so that the slipping or relaxing of the grip of the feed rollers indicates when the length of one slip has been fed. A separating-edge 12 behind the feed-rollers guides the record strip into the filing chamber 13, and directs the other strips out of the machine. The lower edge 55 of the separator forms a cutting-edge against which the record strip is pulled by a pair of gripping members 15, 16 operated by a manual lever 17. The filing-pins 21 are carried upon a shaft 20 and are oscillated by means comprising an arm 32 pivoted at 31 and carrying an eccentrically journaled disc 46 which is adapted to engage a disc 47 on the driving-shaft 7, a vertically guided link 33 at the end of the arm 32 being thereby moved downwardly so that a lug 34 at its lower end engages a lever 26 pivoted on the shaft 20. A lug 29 on the lever 26 is normally held against an arm 22 secured on the shaft 20, and causes the filing pins to be moved away from the rollers 6. The eccentric disc 46 is normally held away from the disc 47 by a dog 51 which is pivoted on the shaft 14 carrying the lever 17 and is provided with a lug to engage a lug 44 on the pivoted arm 32. When the lever 17 is actuated to sever a record slip, an abutment thereon engages dog 51 and swings it anticlockwise, whereupon the discs 46, 47 engage. Subsequent rotation of the crank to feed fresh slips into the writing position causes the link 33 to be depressed to move the filing-pins away from the feeding-discs 6 and across the free end of the incoming record slip. Further rotation of the crank causes the lug 34 on link 33 to slip past the lug on the lever 26, whereupon a spring 23 connected to arm 22 pulls the filing- pins back again so that their curved ends enter the perforations of the record slip. When the arm 32 is depressed by the eccentric disc 46, the cutting-lever being then in its inoperative position, a spring 43 returns the dog 51 so that it engages the lug 44 on the return of the arm 32. The lever 17 for actuating the slip-severing mechanism forms an extension of an arm 42 which is pivoted on a shaft 14 and carries one member 15 of the pair of grippers, a spring 19 normally holding the arm 42 against a stop 54, with the member 15 clear of the tearing-edge 55. The co-operating gripper 16 is pivoted on a shaft 56 and normally held against a stop 53 by a spring 52. Upon depression of the lever 17 the gripper 15 is lifted and coacts with the member 16 causing the strip to be pulled against the cutting- edge 55 of the strip separator 12. Preferably the members 15, 16 have roughened edges to increase their grip on the strip, and the edge 55 is shaped so that tearing commences simultaneously at two points adjacent to the feeding-rollers 6.
