Abstract: 2990. Joy, D. G. Feb. 7. Typewriters ; copy-holders for typewriters.-Relates to a machine for printing weight, measure, money, &c. items and totals, and comprises series of type-wheels rotating on one axis and set by a single lever and disconnectible gearing, and an arrangement of parts so that the original copy, the dial for the setting-lever, and the printed matter are in the same plane of view and adjacent to each other. The items for a line are separately printed. Figs. 1 and 5 show a machine for printing gross and tare weight items and totals. The item-wheels 47<a>, 47<b>, 47<c>, 47<e>, 47<f>, 47<g> are loose on a shaft 66 rotated by means of gearing 26, 27 and a handle 1 working in a graduated slot. Each item-wheel carries an eccentric disk 73, Fig. 3, guided by pins and slots 51 and formed with a half-round and half-square hole for connexion with a squared part 50 of the shaft 66. The disk 73 is normally held raised by means of a rod 52 and spring 31, and is depressed by means of a lever 34. The several levels 34 are successively operated by means ( f spaced cams 42a, 42b, 42<c>, 42<e>, 42<f>, 42<g> on a sleeve 42 loose on a shaft 43 and rotated by a handle 13 on the sbaft 43 and pawl-and-ratchet gear 70, 702. The cams are so shaped and arranged that a halfstroke forward of the handle 13 throws the last item-wheel out of gear and brings the next itemwheel into gear Consequently, in operating the machine, the handle 13 is given a half stroke forwards, the handle 1 is moved forward to set the item-wheel, the handle 13 is moved full forwards and full backwards, and then the handle 1 is moved backwards to return the itemwheel to blank position. The slot for the handle 1 is notched, and the handle is provided with an indicator 2 fitted with a spring catch taking into the notches. The totalwheels 22<a>, 22<b>, 22<c>, 22e, 22<f>, 22<g>, 22h are arranged beside the item-wheels, and actuated by internal ratchet gears 24 and counter gear for reducing to proper denomination. The total-wheels are of sriialler diameter than the item-wheels, and the blanks of the item-wheels are accordingly of reduced diameter to allow of printing from the total-wheels as shown in Fig. 1. The total-wheels are normally locked by pins 52<1>, Fig. 3, on the rods 52. A type-wheel 47<h>, Fig. 5, for line numbering, is set by a wheel 71 on the cam-sleeve 42 and gear 72, 73. The paper is led from a roll 49 over rollers 17, 18, 16 in swinging arms 11 and out under an inspection opening 14 and over a tray 8. Tension is maintained by a spring roller or, as shown, weighted rollers 6. Line-spacing is effected by means of a toothed wheel 39, Fig. 3, on the roller 17 and a pawl 40 set in position to be ergaged by the wheel 39 by connexion with the lever 34 of the end item-wheel 47<g>. The arms 11 are connected by links 12 and crank disks 29 to the shaft 43. For printing totals, the pawl 70<2> is disengaged from the ratchet-wheel 70, and the roller arms 11 are shifted laterally by means of a sliding shaft 11<1> provided with a head 101 and retained by a key 100. An inking-roller 15 travelling over an adjustable pad 19 is actuated by connexions 28 with the disks 29. The copy is held by a roller 4 and a line-marking bar 7. Reference is made to Specification No. 2990A, A.D. 1906. (2) In the machine described in the Provisional Specification, the item-wheels are set by one or more levers or from a rotating dial through disconnectible gearing controlled by keys, one for each item wheel. There is an extra type-wheel for numbering and dating. A sliding paper carrier is actuated by a handle. The impression roller is provided with ratchet mechanism and a handle for line-spacing, and carries a line-counting dial. - The line-spacing mechanism may be actuated from the impression handle. A fixed inking roller or pad is used. The line-marking bar of the copy-holder may be automatically moved by a band attached to the shaft of the paper roller. The item-wheels are connected with separate counter dials for registering totals, and there may be gear for reduction to proper denominations. The counter dials may be connected with type-wheels for printing totals. The dial for setting the item-wheels may be in the form of a ring, and may be stopped at any desired point by pins, which may be worked by levers on a keyboard. The scale co-operating with the dial may be movable to follow the dial. A stop may be provided on the dial for use in setting successive identical numbers. The gross and tare wheels may rotate in opposite directions and connect into a common wheel to give net weights.
