Abstract: 24,991. James, R. W., [Remington Typewriter Co.]. Nov. 3. Sheet feeding and guiding arrangements.-(1) The apron is supported at the rear solely by springs and at the front by means which guide the front outwards and downwards when the apron is released from the platen. In the arrangement shown, the apron 17 is slung at the rear on two springs 20, and is supported at the front by a cross-bar 12 which engages lugs 18 on the apron and is secured to arms 10, 11 pivoted in the end-plates 4 of the carriage. The springs are secured to a bar 21 on the carriage and normally hold the front of the apron against the platen 5. The apron is released by means of a band-lever 23, which is pivoted at 24 to the left end plate 4 and is provided with a flange 25 adapted to engage an arm 26 on the arm 10. When the hand-lever is pushed to the rear, the end of the flange engages the arm 26, and the cross-bar 12 is moved outwards and downwards against the tension of the springs 20 and the apron released. The face of the flange is concentric with the pivot 23 and engages the arm 26 when the apron is in the released position, the springs 20 then acting to hold the apron in the released position. (2) The paper-fingers each consist of a curved sheet-engaging finger 27 formed with a depending spring 28 and with a lateral arm formed at the ends with hook-parts 31, which are arranged at the rear of the cross-bar 12 and embrace about half its circumference. The spring engages part of the carriage 3 and presses the finger against the paper, the hooks 31 serving as a fulcrum. The fingers can be adjusted laterally and can be detached by pushing the hooks off the cross-bar. The finger may be made from a single sheet of metal. The fingers are released from the paper by operating the hand-lever 23. (3) The feed-rollers each consist of a rubber sleeve 47, Fig. 4, secured to a metal tube 46 which is of larger diameter than its axle 33 and is formed with reduced ends which bear on the axle. The axles are each formed with annular grooves resting in open slots in hangers 34 which are mounted independently in the following manner on a rockshaft 37 journaled in the end-plates 4. Each hanger is formed with apertured ears 35, 35<a> which engage the rock-shaft, the ears being connected by a web 36 formed with a slot 41 which engages a stud 42 on the rock shaft. The hanger is pressed towards the platen by means of a wire spring which is coiled round the rock-shaft and is arranged with its ends under the web 36 and with a middle loop 38 under a lug 40 on the bar 21. The hand-lever 23 is formed with a cam 44 adapted to engage an arm 43 on the rock-shaft, the arrangement being such that, when the hand-lever is moved to the rear, the rock-shaft is rotated and depresses all the I angers and carries all the feed-rollers away from the platen. The hand-lever is also formed with a dwell 45 adapted to hold the rock-shaft and consequently the feed - rollers in the released position. The pin-and-slot connexions between the hangers and the rock-shaft renders the hangers independent, but enables them to be moved simultaneously for release. The construction of the hangers and the feed-rollers facilitates assembling. Paper shelves.-The shelf 50 is secured to arms 51 which fit detachably in sockets formed by folded parts 53 of arms 52 on the bar 21 ; or sockets may be formed on the arms 51 to fit over the arms 52. Paper scales.-A scale-plate 14 is attached by screws 15 to ears 16 on the arms 10, 11.
