Abstract: 285,803. Autographic Register Co., (Assignees of Carroll, H. W.). Feb. 21, 1927, [Convention date]. Memorandum appliances.-In manifolding-machines of the type provided with feeding means to draw superposed strips or webs from a zig-zag pile, one or more strips being issued from the machine and a record strip being retained within a. compartment, the record compartment is provided with a pivotally suspended plate or the like which is adapted to engage the record strip when it does not refold properly into its original zig-zag formation, thereby causing the strip to pile up against it into a number of folds until the device yields and the strip drops into the required condition. The sheets are fed in known manner from a supply compartment S, Fig. 1, by co-operating feed-rollers 10, 11, the roller 11 being supported within a housing 19 by brackets 12 which are pulled downwardly by springs 13 at their lower ends to retain the feed-rollers in engagement. The strips are drawn forward over a platen or supporting surface 18, and the issue strips 16 are separated from the record strip 17 by a separator 30 which is interposed between them before they engage the feed-rollers, the strips 16 subsequently passing out through an aperture 20 formed between the cover 23 of the record compartment 24 and a tearing-off bar 21 provided at the lower end of the housing 19. The separator 30, Fig. 5, comprises a thin hard metal blade or plate provided at its forward end with trunnions 31 for pivotally mounting it within holes in the brackets 12 supporting the roller 11, the trunnions and their receiving holes being so disposed that the separator lies in the plane of the bight of the rollers 10, 11. The separator extends forwardly and prevents the issue strips from entering the record compartment, and is provided with cut-out areas 33 to receive the portions of the feedrollers which co-operate to feed the strips. If the record strip fails to fold accurately along its fold lines, due for example to a variation in the quality of the paper or in the depth of the perforations at the fold lines, the strip is held up by the plate 34 which is hinged at 35 to the cover 23 of the record compartment and engages the web so that it folds normally along its predetermined lines of fold 38, 40, Fig. 1. The irregularly folded strip is folded zig-zag into a pile which, on account of it.s weight, assumes a curvilinear configuration between the plate 34 and a rear plate 42, until the weight is sufficient to cause the plate 34 to swing outwardly and allow the pile to drop, whereupon it assumes its correct form. The plate 34 may be suspended from a slotted plate 62 which is secured by a screw 60 to enable its position relatively to the feed-rollers to be varied in order to predetermine the thickness of the pile that accumulates on it. The plate may also be biassed by springs. To assist the folding of the record strip a deflector 48 extends upwardly from the back plate 42 of the record compartment and curves rearwardly towards the feed-rollers 10, portions being cut out from the edge of the deflector to receive the rollers 10 and form fingers 49 to receive and guide the record strip. A deflector plate 55 secured to the hinged front end of the top plate 23 facilitates the guiding of the record strip. Specifications 196,291 and 236,580 are referred to.
