Abstract: 268,295. Slezak, V. F. March 24, 1926, [Convention date]. Printed records, apparatus for giving.- A coin-controlled weighing machine prints and delivers a record of the weight of the person using the machine, and also of the date, the records being printed on a strip 39, Fig. 2, which is automatically fed forward, on each weighing operation, between printing wheels 18, 54 and a hammer 56 located below the wheels; the end portion of the strip is severed after printing, and while it is in the printing position, whereupon it falls down to a delivery aperture. A special coin shoot is provided to delay the fall of the coin from the receiving slot to the mechanism which it controls, sufficiently to enable the type-wheel which is set to the proper position by the movement of the weighing-platform, to come to rest before it functions. An " accordion folded " strip 39, Fig. 2, is stored in a holder 40, and passes round a feed-roller 41 past a severing-device, the free end portion of the strip lying between guides 53 beneath the type wheels 18, 54. The severing-mechanism comprises a fixed blade 42 and a movable blade 43 which is pivoted at 44, its end projecting through the main plate 15 of the framework into engagement with a lever 48, Fig. 3. This lever operates to raise the blade against the action of a spring 47, to sever the strip, as described below. A spring-controlled arm 51 holds the blade 43 in contact with a guide-plate 50. The operation of the machine is as follows. When the user steps on the platform (not shown), which is pivoted to a frame connected by a rod 37 to a cross-head 34 suspended by springs 36, Fig. 3, the type wheel 18 is set in accordance with the movement of the platform. The setting is determined by means of a cam 26, controlled bv the crosshead 34 and supporting a rack 23 which gears with a pinion on the spindle of the type wheel. The position of the cam can be adjusted as necessary by means of a screw connection of the rod 32 to the cross-head, and the shape of the cam can be corrected as required, by filing, without removal from the machine. In addition to the weightprinting wheel 18, manually-adjustable type wheels 54 are provided for printing the date. As the platform is depressed, relative movement between the platform and the frame to which it is pivoted causes a lever to be temporarily rocked and to lift a rod 106, which is attached to a weighted bar 79, the bar when lifted being held up by a catch 96, 98. The raising of this bar simultaneously effects three operations, viz. : (1) the strip 39 is fed forward by means of a pin 73 on the bar acting on pawl-and-ratchet mechanism 66 - - 70, Fig. 2 : (2) an inked ribbon 61 passing between the type and the strip 39 is moved forward by a pawl 65 on the bar actuating a ratchetwheel 64: (3) a coin shoot 11, Fig. 3, is so moved that a subsequently-inserted coin is directed into a shoot 12, down which it falls on to a lever 17. Its weight tilts this lever, and frees a lever 86 from a catch 85. Upon the relase of the lever 86 by the action of the coin, the lever is pulled upwards by a spring 88, and a pin 90 thereon lifts a bar 91. This turns a latch lever 77 out of engagement with a bell-crank lever 74 on the spindle 57 of the printing hammer 56, whereupon a spring 59, Fig. 2, in which power has been stored by the previous operation of the bar 79 (as explained below) causes the hammer to print the ticket. As the bar 91 moves upwards, it is forced laterally by the engagement of a part 93 with an inclined recess in the bar, thus releasing the pin 90 and allowing the lever 86 to rise further and lift the catch 96. The weighted bar 79 then drops and as it does so a pawl 100 thereon turns the lever 48 and raises the cutting blade 43, severing the printed ticket. The pawl 100 is tilted by a stop 105 after actuating the lever 48, thus allowing the spring 47 to reset the cutting-mechanism. Finally, the pin 73 on the bar 79 resets the lever 86 by depressing it into engagement with the catch 85; and a roller 81 carried by the bar 79 engages the bell-crank lever 74 on the spindle of the printing- hammer, turning it so that the spring 59 is extended in readiness for the next printing operation, the latch 77 again coming into action.
