Abstract: 361,886. Weighing- apparatus. CU•NOUD, F. E., 104, Rue Bertrand de Goth, Bordeaux, Gironde, France. May 23, 1930, No. 15979. Convention date, May 23, 1929. Void [Published under Sect. 91 of the Acts]. [Class 143.] Printed records, apparatus for giving.-The invention relates to ticket printing and issuing mechanism for weighing-machines. The machine is operated by a downward movement of a handlever 99, Figs. 3 and 4, that is locked by a vibrating device described in Specification 339,165, [Class 143, Weighing-apparatus], until the weighing-mechanism has come to rest in balanced condition. The actuation of the handle effects in succession, the clamping of a rotatable plate 1 normally connected to the weighing-mechanism, the disconnection of the plate 1 from the weighing-mechanism, the positioning of three rigidly-connected stepped discs 31, 32, 33, Fig. 5, to correspond with the setting of the plate 1, the actuation of a device to ascertain that the position of the stepped discs corresponds to that of the pointer, the operation of printing- mechanism, Figs. 7, 9, 13, controlled by the stepped discs, and lastly, the removal of the brakes from the plate 1 and its reconnection to the weighing- mechanism. Setting-means. The plate 1, Figs. 1 to 4, is pivoted on a knife-edge 2 and is normally connected to a knife-edge 7 of the weighing-apparatus by an arm 6 extending from the knife-edge 7 into a stirrup 3 slidable in the plate 1, in the manner described in Specification 339,165. When the weighing- mechanism has come to rest in balanced condition a knob 101 in the handle of the lever 99 becomes operable to release the lever. Depression of the knob 101 also serves to rock a shaft 105 connected to a lower shaft 109 with the result that a pawl 20, Figs. 1 and 2, is tripped to allow a spring-loaded bar 15 to descend and apply brake blocks 8 to the grooved plate 1. As the bar 15 falls, a lug 22 thereon trips a pawl 21 to allow a second spring- loaded bar 16 to descend and thereby actuate a member 12 to raise the stirrup 3 and disconnect the plate 1 from the weighing-apparatus. A toothed sector 26, Fig. 3, meshing with a pinion 27 rigid with the stepped discs 31, 32, 33, is rotated into a position in which a stop 28 thereon abuts a balance weight 29 on the plate 1, being connected for this purpose to an arm 117 of the operating-lever 99 by means of a spring-loaded, lost-motion link 119. The impact between the stop 28 and weight 29 is reduced by a dashpot 34, the piston 136 of which is connected to the toothed sector. A fixed conical rod 134 co-operates with a hole in the piston to increase the damping effect as the sector rotates. The operating-lever 99 is provided with a full-stroke pawl 114 co - operating with a fixed arcuate rack 113 having end stops 115, 1151 to reverse the pawl. In addition, a catch 123 is pivoted to the rack to reverse the pawl 114 and thereby prevent a sufficient movement of the operating-handle 99 to actuate the printing-mechanism in the event of the deflections of the stepped discs and indicating pointer being unequal. For this purpose the catch 123 is operatively connected to the axially slidable spindle 127,Fig.4, of a disc 126 rotatable with the stepped discs. As the operating-lever is depressed, a pawl 120 thereon rotates the catch 123 and causes the disc 126 to move towards an index 128 rotatable with the indicating pointer. If the setting of the stepped discs is correct, pins 129 pass through holes 129<1> in the disc 126 and allow the catch 123 to swing into inoperative position, but if the pins abut the disc, the catch is retained in position to limit the movement of the operating-handle. The printing-mechanism is operated by a toothed sector 94 connected to the operating-handle through a lost-motion link 131. At the completion of an operation, the plate 1 is unclamped and reconnected to the weighing-mechanism by a slide 23, Figs. 1 and 2, carrying the pawls 20, 21, the slide being first depressed by the operating-lever to engage the pawls in their notches in the bars 15, 16, and then raised together with the bars by a spring 25. Printing-mechanism. The printing-mechanism is controlled by a shaft 69, Figs. 7 and 9, that receives one counterclockwise revolution from the sector 94 during each operation of the machine. At the beginning of a revolution a cam 70 on the shaft allows rack bars 44, controlling type-wheels 36, to move into abutment with the peripheries of the stepped discs 31, 32, 33 under the action of springs 73. Further rotation of the cam, through lever 75 and link 77, actuates a platen 68 to impress the ticket strip 80. Finally, after the strip has been fed by rolls 87, 88, the cam 70 operates a knife 93 to sever the ticket. The strip is fed by an arm 81, Fig. 9, rigid with the shaft 69 and carrying a pawl 82, the free end of which presses against the periphery of a fixed snail cam 83. A lug on the pawl is thus caused to engage one of four pins 85 on a gear 84, that is thereby rotated through a quarter of a revolution and through idler 86 actuates the feed-rollers 87, 88. The tickets are consecutively numbered by means controlled by the platen 68 and may each receive a similar imprint from the feed-rollers. Two or more tickets may be printed and issued during each machine operation. Means for printing a half-unit may be provided, such means comprising a printing sector 46, Fig. 13, set in accordance with the relative positions of the units rack-bar 44 and a slide 51. The slide is arranged parallel to the rack-bar and is connected thereto by a spring 53, the slide and bar being provided with superposed feelers 56, 57 to contact with the periphery of the stepped disc 33. According to the manner in which the feelers engage the steps on the disc, the slide is moved more or less relatively to the bar, and a slotted member 62, carried by levers 59 on the slide, is raised by the engagement of a pin 65 on one lever 59 with a slot in the rack bar. A pin 50, embraced by the slot 63 in the member 62, is carried bv a toothed sector 48 and through pinion 47 positions the type sector 46.
