  • My invention relates to improvements in machines or apparatus for automatically sorting, evaluating or accounting of records such as cards or strips of paper, and more specifically to control mechanisms for such machines.
  • the object of my invention is to provide an electrical control device for sorting, evaluating or accounting machines and apparatus of simplel construction and great reliability, which is applicable to all machines and apparatus equipped with feeler or selector lever contact devices or similar arrangements and which need not be directly controlled by the perforations or other symbols of the card.
  • This object is according to my invention attained by means of a contact drum or cylinder provided with rows of contacts distributed over its circumference, each row forming part of one of a plurality of normally open circuits which include contact brushes or other contact closing means, preferably arranged in a row, in con--v junction with contacting devices or switches controlled by the cards, each of such circuits being adapted to control the electrical driving or switch gear of the machines or apparatus, and arranged to be closed upon actuation of certain of the contacting devices when a card perforated in a predetermined manner is fed to the machine.
  • a separate contact drum with brushes or contact closing means is provided for each set of feeler levers coordinated to the combination values of a decade number, an identification value or the like, all the contact drums being connected in series through their end contacts.
  • the contacts in the rows located axially to the drum are thus combined into combinations controlled feeler lever contacting or switch devices belonging to them, each of which combinawith the card# tions is associated with a certain numerical value.
  • Fig. 3 a development with connection diagram of an arrangement with four contact drums for setting tens values formed'by combination values
  • a perforated card in its position on the guide plate of a sorting or evaluating machine in plan
  • Fig. 6 a section along line A--B oi Fig. 5 with the feeler lever contact arrangement.
  • I is the shell or cover of the contact drum 2, upon which are located, in rows and diiferentlylspaced, contact faces 3 in the form of salient plates. A number of these contacts are connected by leads 4 in the interior of the drum 2.
  • a row of contact brushes 5 parallel to the spindle 1 in such a manner, that they slide upon the contact faces 3 of the drum.
  • the contact brushes 5 are preferably rigidly mounted at the machine framing or any other stationary part 6, while the drum is adapted to revolve around its spindle 1.
  • a pointer 8 attached to the drum 2 and a stationary graduated disc 9 ⁇ any desired row of contacts may be brought in contact with the brushes 5.
  • each of-the feeler levers I2 located in a row below the guide I I for the perforated cards II) controls the central one of the three contact springs I4, I5, I6 by means of an insulated pin I3.
  • the central contact spring or switch I5 is ac-k cording to the position of the feeler lever I2 forced against the nose of the upper spring I4 or that of the lower spring I6. 'Ihe central spring I5 of the feeler lever contact arrangement located at the extreme left in Fig. 1 is connected to the positive pole and the contact brush l of the same drum at the extreme right to the winding I1 of any driving or control member of the sorting or evaluating machine. leads directly or through other driving or control members to the negative terminal of a source of current.
  • the feeler levers I2 are located in a row transverse to the travel direction of the card below the guide track II for the perforated card. For each vertical row of lthe card there is provided a feeler lever I2 with contact springs I4, I5, II.
  • may according to Figs. 1 and 2 be used by itself or, according to Figs. 3 and 4 in connection with contact drums of like kind or, as indicated by the dotted lines between Figs. 1 and 3 in connection with contact drums which diier from one another in regard to the number of the adjustable lvalues.
  • of Figs. 3 and 4 may, for instance, be employed for the groups of columns 22 to 25 of the card III in Fig. 5 and the contact drum 2 in Figs. 1 and 2 forthe groups of columns 26 of the card III.
  • my improved control apparatus is as follows: prior to the commencement of the sorting or evaluation of cards or strips of paper I0 punched with perforation symbols, one or more of the contact drums of the machine or apparatus are set for the values according to which the cards or strips of paper should be sorted or evaluated. If, for instance the cards are to be sorted out, according to the values punched only in the group of columns 26, which in the illustrated example contain the value 20 in perforation symbols, the contact drum 2, which is employed in the present case to control sorting, is set at 20 and the contact drums Ii to 2
  • the contact drum Il is set on the value 5, the drum I9 on the value'l, the drum 2Il on the value 4 and the drum 2
  • the third and fth feeler levers I2 of the contact drum arrangement 2 according to Fig. 1 pass through the perforation symbols 21 and 22 of the card III in Fig. 5 and cause the central From here a conductor4 springs Il to move into contact with the upper contact springs I4.
  • the central springs Il make contact with the upper contact springs I4, while in the contact arrangements apportioned to the remaining column values I, 2, l and I2 the central springs Il are in contact with the lower springs I0.
  • the horizontal row of contacts I on the drum 2 coordinated to the value 20 (see horizontal row 20 in Fis.
  • the contacts are so arranged and are so connected with each other directly or through the switch contacts I4, Il and II, that at the moment when the card I 0 is searched by the feeler levers, a circuit is closed from the positive pole (see upper left-hand corner of Fig. 1) across some of the feeler lever contact springs I4, Il, Il as well as through some of the brushes l and across the contacts I of the row corresponding with the value 20 in predetermined sequence, to the winding I 'I and thence to the negative pole.
  • the contacts 3 of the correspondingly numbered horizontal row of drum 2 are connected in series so as to close the circuit through the controlling element I1. This circuit will obviously be closed every time a card having the given value punched in columns 2t is fed to the machine.
  • the contact sets corresponding with the values I and 4 are in similar manner set at the contact drum I B, at the drum I9 the contact sets belonging to the values I and 2, at the drum 20 the contact set apportioned to the value 4 and at the drum 2
  • any desired number of sorts of cards may by means of the new control mechanism be picked out automatically from a large number of cards and sorted.
  • the feeding of the perforation values by the feeding levers I2 takes place in rows, it is possible to take up a plurality of values entered in different rows of the card of the same kind (for instance of the same account) in one operation, i. e. during a single passage of the respective card III through the machine, in its counting and calculating mechanism and to evaluate them, by adding up the values or entering the balance.
