Abstract: 271,036. Egry Register Co., (Assignees of Jackson, P. A.). May 15, 1926, [Convention date]. Memorandum appliances; carbon papers, arrangements of.-In autographic registers having superposed sheets with holes therein at spaced intervals to co-operate with means for regulating the alignment, co-operating ejecting rollers 37, 56, Fig. 8, are mounted upon shafts 38, 44, the roller 37 being separated from rollers 39 at each end of its shaft by spaces 40 which receive aligning pins 41 on sleeves 57, 58 at each end of the roller 56. The pins 41 rest upon the top of the sheets during the feeding action and drop into the holes when the latter come beneath them, the feeding rollers being separated and rendered incperative at this stage by cams 59, 62 at the ends of the sleeves, which bear upon the lower rollers 39. The ends of the shaft 44 of the upper feed roller are mounted in two vertically slidable plates 71 which are pulled downwardly by springs 76 at their lower ends and may be cammed upwardly to insert the webs by a shaft 89 provided with flats engaging within slots 92, Fig. 3, in the plates. The upper roller shaft 44 is driven by a pinion 43 engaging a pinion 42 on the shaft 38, the latter being driven through pinions 45, 47, by a pinion 48 on the operating shaft 49. The operating handle is arranged to feed the sheets during a. single continuous movement which is limited by a spring-controlled abutment member pivoted on the side of the casing. The shelves 57, 58 are so mounted upon the shaft 44 that they can rotate independently of the central roller 56, and for this purpose their outer ends are recessed to receive helical springs 60, 64, Fig. 7, the inner ends of which are secured to the sleeves, the outer ends respectively being secured to the pinion 43 and a collar 65 at the other end of the shaft 44, Fingers 67, Fig. 14. secured near the ends of a shaft 46! are normally held either in engagement with the cams 59, 62 or in their path, by means of a tensioned spring 70 secured to the rear end of one of them, thereby controlling the rotation of the sleeves 57, 58 upon which the cams are fixed. The feeding rollers are separated to align the sheets in the writing position by turning the head 90 of a shaft 89, and the pins 41 are positioned vertically within the registering holes of the sheets. In this position the noses 68 of the retaining fingers 67 are in engagement with the cams. When the operating handle is turned a stud on the driving pinion 48 engages one of the fingers 67 and turns the shaft 46 so that the cams 59, 62 are released, and the sleeves 57, 58 turn with the shaft 44 until the ends of the pins rest upon the sheets as the latter are being ejected. The shaft 44 and the central roller 56 continue to turn, while the sleeves 57, 58 are held stationary by the pins contacting with the paper, thus increasing the tension upon the springs 60, 64 until a pair of rollers in the sheets coming beneath the pins allows the sleeves to turn and relieves the tension of the springs. The sleeves turn until the pins are in a vertical position, and simultaneously the cams on the sleeves operate to separate the feeding rollers, allowing the sheets to align upon the tapered pins. Carbon supply sheets are disposed within a casing 78 on a spindle 79 at one side of the machine, and are interleaved between the webs and held by a pivoted clamping bar along the other side of the casing. Web reels 34-36 are supported on spindle 19 within gearing notches 20 formed in plates 18 which are mounted on brackets 17 on the sides of the casing. The ends of the spindles are retained within their bearing notches by overhanging lips 29 formed by notches in the edges of plates 24 which are slidably mounted on the plates 18 and pulled rearwardly by a spring 30.
