Abstract: 401,524. Autographic recorders. PFEIFFER, F. E., 2124, Malvern Avenue, Dayton, Ohio, U.S.A. Jan. 12, 1933, No. 1106. [Class 106 (i).] In an autographic recorder of the kind comprising means cooperating with the writing table of the recorder for aligning the strips of paper at previously formed creases therein, the writing table has a sharp edge near the rear end, feeding means pull the strips over the sharp edge and act during the whole cycle of operation of the recorder, and means is provided for alternately moving the strips forward against the edge during the pulling action so that the strips are aligned or re-aligned when their creases engage the edge, and change the angularity of movement of the strips around the sharp edge to permit continued movement of the strips due to the pull. The casing of the recorder carries several cross-bars 14, one of which pivotally supports a writing table 16 provided with a slot 18 which is sharpened along the front edge 19 for engaging creases in the paper 68. A presser-plate 19a extends over the slot 18 to retain the paper strips on the table at this point. A frame for guiding the paper strips at an acute angle to the sharp edge 19 is pivoted at the rear of the slot and consists of a cross rod 20 bent at the ends to engage bearing brackets on the under side of the table, and attached to the side arms 21 of the rod 20 is a second cross rod 24, both cross rods and the arms 21 forming a slot through which the strips of paper pass. The frame is spring-pressed towards the table 16 and is spaced therefrom by a block 25 attached to the rod 24. Attached to one of the side arms of the rod 20 is a link 29 which is pivoted to a slide plate 30 mounted in brackets on the under side of the table, and an abutment 32 on the plate 30 is adapted to be engaged by a finger 52 on a pivotally mounted toothed segment 50 to move the plate 30 and consequently the paper-guiding frame to the right. The paper strips are fed from a zig-zag folded stack through the slot in the paper-guiding frame and the slot 18, and over the table 16 by feed-rollers 35, 39 until a set of transverse creases or perforations arrive at the sharp edge 19 of the slot 18, when the lightly gripping feed-rollers slip over the strips. Further feed can only take place when the paper-guiding frame has been moved to the right so that the strips make an obtuse angle with the sharp edge 19. The feeding means comprises two discs 35 mounted on a shaft 33 rotatable by means of a handle, and a resiliently mounted roller 39 which is geared to the shaft 33. The discs 35 have serrated circumferences and the roller 39 is correspondingly serrated. The roller 39 is pivotally mounted at each end in a plate 41 which is slotted to slide vertically over studs 43 on the casing, and is resiliently attached to a fixed plate 45 by a bolt on which is retained a spring 48. Attached to the shaft 33 is a toothed segment 49 adapted to engage the toothed segment 50. As soon as the gear 49 passes out of engagement with the gear 50 the spring on the paper-strip guiding frame returns the latter and the gear 50 to their initial positions. A stop member is situated in the path of the operating handle to stop rotation at the end of each cycle of operation ; further rotation may be accomplished by pressing the stop inwardly against the action of a spring. Backward rotation of the shaft 33 is prevented by a spring-pressed pawl mounted on one of the rods 14. A cover 55 provided with. a writing aperture is pivotally mounted above the table 16 on one of the rods 14 adjacent the rear of the casing, and is provided with a housing 57 for the roller 39. Another cover 6 is provided with lugs 7 adapted to engage studs 5 on the casing when the cover is slid longitudinally of the casing ; the cover 6 has a lug 9 which engages a lock 8 in the closed position. Duplicate copies are stored in the front end of the casing, and are guided by a frame 10 pivoted to a plate 11 attached to the cover 6. Carbon paper placed transversely of the table 16 is supplied from a shaft situated in and extending beyond a housing on one side of the main casing. A washer on the shaft is spring- pressed into engagement with the roll of carbon paper. The end of the carbon paper is clamped to the opposite side of the casing by a pivoted and latch-retained plate. Specification 363,742 is referred to.
