Title: Improvements in carbon-paper feed devices for autographic registers and like writing and recording machines
IPC: B41L5/06
Filed: 1949-08-09
Abstract: 678,720. Feeding webs. LAMSON PARAGON SUPPLY CO., Ltd., and CASTLETON, A. E. Aug. 9, 1950 [Aug. 9, 1949], No. 20715/49. Class 100 (i). [Also in Group XV] Feelers and detectors.-An autographic register or like writing machine is provided with a signalling or warning device to indicate when the carbon roll is substantially exhausted, the means for actuating the device comprising a lever oscillated each time the register is operated, the extent of the oscillation being controlled in accordance with the diameter of the carbon roll so that when the supply is nearly exhausted the lever moves sufficiently to actuate the warning device. As shown, the spindle 4 of the carbon roll a is positioned in slots 5 in a casing 1 and the carbon paper b is drawn off by feed rollers 2. The free edge 8 of a pivoted plate 7 rests on the roll and carries a pin 9 supporting a pin 13 on one arm 10 of a bellcrank lever 10, 11, pivoted at 12, and oscillated at each operation of the register by a crank 21 on a shaft 22 carrying a disc 3 for feeding a form length of stationery at each operation. The arm 11 engages a pin 17 on a hammer 16 pivoted at 18 and biassed by a spring 19 towards a bell 20, so that the hammer 16 is oscillated by the lever 10, 11. The limitation of the movement of the arm 10 by the pin 9 prevents the hammer from striking the bell until the carbon roll is nearly exhausted and the pin 9 has dropped sufficiently to permit of the necessary extent of movement. A pin 14 on the arm 10 moves over a scale 15 to afford a visual indication of the amount of carbon paper remaining on the roll. Longitudinal tensioning.-The plate 7 also serves to maintain the carbon paper taut as it is drawn across the writing plate, undue strain on the paper being prevented due to the release of the pressure of the pin 13 on the pin 9 when the arm 10 is raised at each register operation.

Abstract: 405,893. Weighing - apparatus. TOLEDO SCALE MANUFACTURING CO., Monroe Street, Toledo, Ohio, U.S.A. July 27, 1933, No. 21122. Convention date, July 27, 1932. [Class 143.] Automatic-feed weighers ; indicating - mechanism.-The weighing- mechanism of a weighing-scale is adapted to vary the amount of light supplied to photo-electric means, the latter upon a diminution in the amount of light supplied thereto controlling one operation of mechanism, and upon a subsequent increase in the amount of light supplied thereto controlling a different operation of such mechanism. The material to be weighed flows from a supply shoot 85, Figs. 1 and 2, through funnels 84, 83 and electrically-operated main and dribble feed gates carried by a support 45, to a bag (not shown) supported on a commodity grid 14 and maintained in open and upright condition by a shoot 98. The commodity grid is carried by an equi-armed balance provided with a weight-plate 15 and connected to a pendulum resistant 28. An index 27 carried by the pendulum co-operates with a chart 30 having a zero indication 31, the chart and index being rendered visible to the operator by means of a mirror 86, Fig. 2. The index terminates in an enlargement 41, the lateral edges of which would, if extended, pass through the pivotal axis of the pendulum. The main and dribble feed gates 58, 57, Fig. 6, are opened by solenoids 52, 51 energized by depressing an electric push button, and the material flows into the bag until the leading edge of the enlargement 41 obscures a slit 361 through which light passes from a lamp 39, Fig. 4, to a photoelectric element 32. The resultant obscuration of the element causes the main feed gate to close and partially obstruct a part 48 of the feed shoot. A dribble feed continues until the trailing edge of the enlargement 41 passes the slit 361, when the photoelectric element is re-activated and causes the cut-off of the dribble feed. The feed gates are normally retained in closed position by springs and the travel of the main feed gate 58 is controlled by an adjustable stop to vary the rate of dribble feed. Compensating for material in suspension at cut-off. The photo-electric element 32, Fig. 4, and its illuminating lamp 39 are connected by an arm 37 and are adjustable as a unit about a vertical supporting rod 35 to enable the position of the slit 36<1> to be adjusted relative to the zero indication 31, Fig. 3, and thus compensate for the material in suspension at cut-off.
