Abstract: 251,976. Goetzmann, J. May 11, 1925, [Convention date]. Multiple - indication apparatus. - An automatic weighing balance for indicating and recording the weight, the unit price, the total cost of the goods on the scale pan, and for recording the number of weighings and for indicating the total of the takings is provided with a scale beam fitted with a parallel motion or equivalent weighing system and having equal or unequal arms carrying goods and weights pans. and the beam is constituted at the weights-pan side by two parallel rods along which a poise weight may be traversed by a screw controlled by an electric motor adapted to be automatically started, stopped, and reversed; the screw is connected to a revolution counter adapted to indicate the weight, and the poise causes, at the limit of its travel in one direction, additional weights to be placed on the weights pan so as to permit the carrying out of the weighing operation by a reversal of the movement of the poise, the poise being returned to its zero position after the removal of the goods, the additional weights being lifted off the weights pan and the motor being stopped. The shaft 91, Fig. 1, of the weightindicating counter drives the total-cost indicating system through four gear boxes g<1> (one only shown). The driven shafts 118, 123, 125 and 128 of the four gear boxes may each be given various speeds according to the settings of the gear-box actuating forks. A set of keys is provided for setting the forks of each gear box, the complete bank of keys being shown in Fig. 24, each key being inscribed with its value in francs. The operative connections of one of these sets is shown in Fig. 22, the remaining sets being similarly arranged. The keys 139 - - 142 project from a wheel 137, and in effecting a setting operation the wheel is rotated by the appropriate key until the operator's finger comes against an abutment 144. A catch 145 engaging notches 146 holds the wheel in accurate position. The wheel rotates a face cam 133 through intermediate pinions 136 - - 134, and the face cam engages the arms of the actuating forks of the gear box and effects the correct setting of the gears. The gear boxes are coupled to one another through epicyclic trains 160, 165, 168, Fig. 1, so that the speeds transmitted through the gear boxes are added up, and the accumulated movement is transmitted to a shaft 171<1> which drives a revolution counter 171 indicating the total cost of the goods. A totalizing counter 213 adds up the various costs. The price per unit-weight is displayed upon an indicator 175 driven from the wheels 136, Fig. 22, through epicyclic trains. When the balance is in equilibrium, and has ceased to vibrate, the operator may zeroize the price indicator and cause the price keys 139 - - to return automatically to zero under spring action by depressing a contact button. The indications of weight, price and cost may be shown on both sides of the machine. In order to permit a supervisor to check the settings of the price keys from a distance, electrical contacts are arranged in the notches 146, Fig. 22, and form part of the circuit including a switch for actuation by the supervisor and a number of electromagnets actuating price-indicating discs corresponding to the price keys. A selection of indicating discs is thus displayed through apertures according to the setting of the price keys. The type wheels 91<1>, 171<11>, 175<11>, Fig. 29, are rotated in correspondence with the movements of the weight, price, and total cost indicators, and a further set of type wheels 191<1> are provided for printing the date and the number of the weighing. When the operator depresses the contact button to zeroize the price indicator, a rod 194 is drawn upwards by a solenoid 180, and the lower end of the rod actuates printing levers 196, 196<1> so as to make a duplicate record on two strips passing from rolls 190, 191. During the continued upward movement of the rod, projections 202, 208 thereon ,actuate first a ratchet device 207 to feed the strips forward and then cause a knife 210 to cut off the printed end of one strip and deliver it down a guide 193, the other strip being retained within the apparatus upon a roller 102. A series of press buttons 211 enable each salesman to print his own identification mark on the ticket.
