Abstract: 474,986. Memorandum appliances. TENNANT, W. J. (United Autographic Register Co.) May 15, 1936, No. 13810. [Class 16] [Also in Group XIX] An autographic register comprises a casing provided with a platen, and an initial feed device comprising a stationary frame having forwardly and downwardly extending stationary guide means, a swinging frame pivotally mounted to oscillate in the stationary frame and having an actuating arm, register pins mounted on the swinging frame so as to be yieldingly urged upwardly against the stationary guide means, the pins being adapted to engage perforations in stationery resting on the device and advance the stationery from over the platen, and movable means adapted automatically to engage the pins, when swung to a forward depressed position, and hold them depressed on the return stroke. The register pins 58 which engage perforations in the stationery to register and feed the latter are carried by a swinging frame 48, Figs. 9 and 12, disposed between the sides of a fixed frame 40 and pivoted on a shaft 43, the pins being mounted in slots in a cross-bar 60 carried by the frame 48 and portions 56 struck out of the sides of the legs of that frame. The pins 58 have shoulders thereon which serve as abutments for springs 63, which urge the pins upwardly, and as stops which engage guide means comprising cam surfaces 45 on the fixed frame 40. The swing- ing frame 48 has an actuating arm 50 to which is attached a handle 51 whereby the frame and pins 58 can be moved forwardly against the action of spiral springs 73 on the shaft 43 until the portions 56 strike stops 72 in the frame 40. The pins are depressed during the forward movement by the cam surfaces 45 on the frame 40, so that the stationery is free, and during the return movement of the frame 48 the upper outer shoulders of the pins engage trigger members 66 which keep the pins depressed until they approach the normal upright position. The trigger members 66 are pivoted at one end to a fixed plate 41 and their free ends are urged by springs 69 into contact with the lateral edges of the pins 58, so that when the pins swing forwardly, the members 66 can move inwardly and over the outer upper shoulders of the pins. A latch member 47 mounted on the fixed frame 40 has a pair of hook members 74, Fig. 12, adapted to engage and hold the cross-bar 60 on the swinging frame 48 when the latter is in the normal upright position. A spring 75 urges the members 74 downwardly, but the rear portion of the frame 48 has a pair of cam arms 76 adapted to raise the members 74 into locking position. The cross-bar 60. is slack fit in the swinging frame 48 and is urged to one side of the slots in the latter by compression springs to constitute a lost-motion device which facilitates the latching and unlatching of the cross-bar. A presser-roll 53 (not shown) is mounted in the frame 48 to co-operate with a rib 38 on the cover of the casing to hold the stationery during writing operations. The casing A of the register, which forms the subject-matter of Specification 475,012, is preferably made of sheet aluminium and comprises a base 10, a platen 12 with rounded guide 13 for the stationery, and a partition 16 forming an upper supply compartment 14 and a receipt compartment 15. The compartment 15 may be provided with a removable tray, and the partition 16 is tapered downwardly at its rear and to facilitate feeding the stationery around the guide 13. An abutment 21 is adjustably secured in the compartment 14 by means of a screw 22 passing through a slot 20 in one of the side walls 18 of the casing. The opposite side wall has a shelf adapted to serve as a container for a roll of carbon strips. A skeleton cover A<1> pivoted at 25 has front, back, and side walls, and a leaf spring 32 secured to the rear wall 30 has at one end a latch 33 adapted to catch a projection from the base 10 and to be released by pressing a button 34, and at the other end is shaped to press the stationery against the platen 12. The front wall 26 of the cover A<1> has a delivery slot 36 provided with a tearing-edge, and a receipt-slip receiving slot 37.
