Abstract: 642,555. Typewriters. HETLEVIK, B., and HAUGE, M. Jan. 17, 1948, No. 1502. [Class 100 (iv)] A front feed account card &c. shoot is supported by a system of arms connected to a frame which may be assembled to a standard typewriter carriage, the arms being'arranged to displace the shoot between a lowered position with its underside in register with the outlet from an apron below the platen roller and a raised position with its underside above and rearwardly of the apron outlet and close to the platen roller. As shown in Fig. 1 the shoot comprises two plates 7, each mounted on parallel links 8 clamped by thumb-screws (providing width adjustment) to rods 9 rotatable in end frames 4, the latter being detachably clipped to the side arms. of the usual paper holding bail 5 ; the shoot is raised by depression of a handle 13 on a rod 14 suitably coupled to one or both of the rods 9, and a connection (e.g. two links) between the latter and the usual line space lever 15 lowers the shoot, as the lever 15 is operated to move the carriage and/or turn the platen roller, until the upper links 8 rest on the rod 14, the arrangement being such that in this position the underside of the shoot is in register with the outlet of the apron 16. After the card has been dropped into the shoot and aligned by bringing the previous line of type into register with guide wires 11 in apertures 10, the shoot is raised and the links 8 constrain its underside to a path substantially concentric with the platen 3 but finally approaching closer thereto, whereby the card is curved backwards sufficiently to hold it steady even if the rolls 17 are withdrawn by the paper release lever. The rods 9, 14 may be telescoped or the clips between the frames 4 and the bail 5 may be variable, to accommodate different widths of machine. In a modification, Fig. 4, the shoot plates 8a are adjustable along a rod 9a rotatable at each end in a bearing on an arm 10a guided by pins 11a engaging arcuate slots 12a in a plate 4a carried by rods 13a, 14a ; depression of a handle on the rod 14a, to which are secured arms 17a carrying pins 18a engaging transverse slots 19a in the arms 10a, moves the shoot to its raised position in which it is retained by a projection on a spring-loaded L-shaped arm 21a engaging beneath one of the pins 11a ; the arm 21a may project backwards to engage a stop on the tabulator. rack, or forwards as shown for operation by the line space lever, to withdraw the projection from the pin 11a. Side members 5a detachably clipped to the paper holding bail 6a support the rod 13a and the whole assembly may be swung thereabout from an inoperative position to the operative position shown wherein the projecting ends of the rod 14a rest on pillars 16a on the carriage end frames ; alternatively an additional rod may extend between-the plates 4a having rolls which rest on the platen 3a. To prevent the card from catching in the apertures for the front feed rolls 27a normally provided in the apron 26a, these apertures may be omitted, and additional grippers in the form of spring tongues 28a, or rolls journalled in the apron, may be provided laterally of the shoot 8a.
