Abstract: 108,336. Triple Record Co., and Browning, W. H. July 5, 1916. Autographic cash recorders; full-stroke mechanism.-Relates to autographic recording and similar apparatus of the kind in which one or more record bands or strips are fed step by step by needles adapted to pierce the strip and consists chiefly in the provision of means for holding and preventing movement of the strip between successive feed movements. As shown applied to a machine provided with three strips, two of which are adapted to have portions torn off while the third is rewound to provide a permanent record, the strips 1, 2, 3 are unwound from spools 6, 5, 4 and pass under an opening in a cover plate 20, the strips 1, 2 being led out of the machine above a hinged part 90 of the cover plate while the strip 3 is rewound by any suitable means, such as that described in Specification 108,337, [Class 100 (i), Feeding and delivering webs &c.], on to a spool 21. The spools 4, 5, 6 are carried at one end in the frame of the machine and at the other in sliding brackets 7, 8, 9 held in normal position by stops 10 on a spring-pressed rod 11 engaging recesses 12 in the brackets. The strips are tensioned by pivoted brake plates 14, 15 resting on the spools 4, 6 and by spring-pressed plates 17, 22 engaging the spools 5, 21. One or more feed needles 52 are carried by a horizontal part 69 of a bar 61 vertically slidable in a bracket 50 secured to a needle feed slide 38 which is reciprocated on a guide bar 40 by means of a main slide 29 reciprocated by a slotted arm 27 on an operating-shaft 24 actuated by a hand-lever or by an electric or other motor. In the movement of the slide 29 to the right, an inclined member 63 upon it first engages a pin 62 on the needle bar 61 to raise the needle and cause it to penetrate the strips 1, 2, 3. A flat spring is arranged to cause the bar 61 to move stiffly. Further movement of the slide 29 brings the upper end of a lever 42 pivoted upon it into engagement with a lug 41 on the feed slide 38 carrying this slide forward to feed the strip until its movement is arrested by a stop 45 on the guide bar 40. Further movement of the slide 29 causes the lever 42 to turn about its pivot against the action of a spring 43, and during this further movement, a lug 66 on the slide 29 strikes one arm of a bell-crank lever 65 pivoted on the feed slide 38, so as to depress the other arm which embraces the pin 62 so as to withdraw the needle 52 from the strips. When the slide 29 is returned, the feed slide 38 is also retracted by means of a bar 47 freely mounted on the operating shaft 24 and pressed by spring 48 against a lug 49 on the slide 38. The return movement of the slide 38 is limited by a stop 46 on the guide rod 40. The needle 52 is guided in a tubular stud 51 secured to the bracket 50 projecting through a slot 53, Fig. 2, in a lever 54 into a slot 55 in the table 56. The lever 54 is mounted on a pivot 57 carrying a second lever 58 adapted to hold the strips down on to the needle and provided with a knife edge 59 on which the projecting parts of the strips 1, 2 may be torn off. The lever 58 is provided with a slot 60 through which the needle projects when raised. The str.ps are held between successive feed movements by one or more retaining needles 68 which are caused to pierce the strips just before the feed needle 52 is withdrawn. A wedge 82 is also caused to raise a plate 85 to grip the strips between itself and the cover plate 20<a>. The needles 68 are carried by a horizontal part 70 of a vertical slide 71 provided with a pin 72 embraced by one arm of a three armed lever 73, one of the other arms of which carries a pin 75, and the remaining arm engaging behind a pin 77 on a slide 78 which is moved to the right to raise the needles 68 by the engagement of a lug 79 on the slide 29 with a pin 80 on the slide 78 just before the needle 52 is withdrawn. The wedge 82 is simultaneously moved to the right by means of its depending pin 84 which is located between two pins 83 on the slide 78. The needles 68 are withdrawn and the slide 78 returned at the beginning of the movement of the slide 29 to the right by the engagement of the inclined member 63 with the pin 75. The needles 68 may be dispensed with, the wedge device being used alone. As shown, the pin 62 of the needle bar 61 engages the arm of the lever 73 and is only indirectly raised by the inclined member 63. The inclined member 63 is pivoted to the slide 29 to allow it to clear the pin 75 on the return of the slide. To prevent straining of the strips by the feed needle 52, the strips are unwound from. the spools by a looper 19 on a pivoted arm 87 which is moved in one direction by a pin 88 on the slide 29 and is returned by a spring 89. The projecting parts 67 of the strips 1, 2 are raised at the end of the return stroke of the slide 29 by means of the pivoted cover plate 90 which is tilted by a tappet lever 91 operated by a pin 44 on the slide. An ink ribbon is arranged between the strips 2 and 3, and tho strip 2 is made of transparent or semitransparent material. To ensure full strokes of the slide 29 in both directions, it is provided with a pivoted pawl 35 adapted to engage with either of two ratchet racks 33, 34 according to the direction in which the slide is moving. A spring-pressed pivoted switch plate 36 is provided to transfer the pawl from one rack to the other.
