Title: Improvements in or relating to autographic recording apparatus
IPC: B41L5/08

Abstract: 431,189. Memorandum appliances. UNITED AUTOGRAPHIC REGISTER CO., 5000, South California Avenue, Chicago, U.S.A. Sept. 28, 1933, No 26777. Convention date, Sept. 29, 1932. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 3, 1934.] [Class 16] [See also Group XIX] The stationery strips of an autographic recorder are held in frictional engagement with each other by means such as a pair of opposed idle pressure rollers, whereby all the strips can be drawn over the platen by a pull exerted upon only one or some of the strips, the pressure means being disabled during the advancement of the strips by an initial feed device. In the embodiment shown in Figs. 1, 6 and 7, the folded strips are drawn by hand from a supply compartment A<1> over a platen A<3> and between pressure rolls 27, 29. A pivoted dividing plate E directs the lowermost strip into a storage compartment A<2>, while a ramp 36 on the plate deflects the leading edges of the upper strips into a position to be gripped by the hand. Severance of the upper strips is facilitated by a cutting edge 25b. Access to the storage compartment is obtained through a lid A<5> provided with a lock 11. Stripfeed is initiated by rocking a lever 18 rigid on a shaft 17, whereby pins 14 passing through holes in the strips are moved to the right to advance the strips. The pins are carried by leaf-springs 15 mounted on a slide 12 having a depending cam surface 13 for operative engagement by a roller 19<a> on an arm 19 of the shaft 17. A second arm 20 on the shaft operates a cam slide 21 to depress the pins at the end of the stroke and disengage them from the strips. Registration of the pins with the holes in the strips may be observed through apertures 25<a> in the casing. The lower roller 29 is carried by arms 30 rigid on a shaft 31 and is urged upwardly by springs to grip the strips. During the initial feed the pressure is relaxed by a counter-clockwise rocking of the shaft 31 that is provided for this purpose with a cam-shaped arm 33 engaged by a projection 34 on the slide 12. In the embodiment shown in Fig. 8, no record is retained in the machine, but a dividing plate and storage compartment could be applied thereto without changing the mechanism. The lower pressure roller 38 is carried by arms 39 rigid with a shaft 40 having an operating arm 40<a>. To initiate the feed of the strips a shaft 45 is manually rocked to the position shown wherein a stub shaft 54 co-operates with the arm to retract the rollers 38. The strips are advanced by spring-urged fingers 47 that are carried by the shaft and are controlled by arms 50<a> mounted on a rock-shaft 50 and adapted to engage flanges 47<a> on the pins. At the beginning of an operation the fingers engage the strips, the arms 50<a> being raised by the engagement of a part 53b of a cam 53 with an arm 50b on the rock-shaft and being held in raised position by a latch 52. At the end of the rocking movement, a part 53<c> of the cam trips the latch to allow the arms to fall and retract the fingers. The remainder of the feed is effected by pulling the strips manually as before. The Specification as open to inspection under Sect. 91 comprises also three modified embodiments of the invention. In the first embodiment shown in Fig. 13 (Cancelled), the initial feed of the strips is effected by telescopic fingers 66 carried by a shaft 63 freely mounted in arms 62<a> rockable about a fixed shaft 62. The shaft and fingers are normally maintained by a spring in the position shown in full lines and are actuated by a handle rigid with the shaft. A projection on the handle co-operates with a fixed cam-member to assist in moving the fingers forward in engagement with the strips and idly rearward. In the second embodiment shown in Fig. 16 (Cancelled), the initial-feed fingers 75 are carried by blade springs 75<a> projecting from arms 73 on an operating shaft 72. The fingers are maintained in engagement with the strips, during the forward rocking, by the engagement of a toothed bar 76 with the upper surface of a rack 78. As the bar passes the rack, it is shifted downwardly by a spring 79 to disengage the fingers, and returns beneath the rack. In the third embodiment shown in Fig. 21 (Cancelled), the initial feed and strippresser mechanisms are similar to those shown in Fig. 8. The record strip is guided into the storage compartment A<5> by a pivoted and weighted flap 17, return movement being prevented by teeth on the flap and on a guide plate 34. Folding of the strip is assisted by a U-shaped arm 65 pivoted on a shaft 66 and rocked upwardly at each operation by the abutment with a roller 69 thereon of an arm 68 on the operating shaft 40. Upward expansion of the stored pack is prevented, while the U-shaped arm is raised, by means of serrated members 70. A full-stroke device is applied to the operating shaft. This subject-matter does not appear in the Specification as accepted.
