  • the essence of the invention resides in the feature of having only one group of analyzing brushes relating to a particular card field connected at a time to control the entries in the accumulator, and after analyzing this card field, a connection between the analyzing brushes for the next card field 1s established to control the entries designated by the second card field in said accumulator, so that after a successive number of such analyzing operations, corresponding in number to the card fields, the result of such analyzing operations is represented by the accumulator.
  • the device constructed according to the invention may be mechanically or electrically operated.
  • Fig. 1 is a perspective view of one form of the invention.

  • connection between the brushes 3 and the contact blocks 10 is such that the contact blocks 10 related to the brushes of one card field are arranged upon a generating line or element of the cylinder.
  • the lines of the cylindrical contact arrangement are thereby carried by the shaft 8 will contact with a formed by as many contact blocks 10 as there are columns in a card field, while upon a 011'- cumferential line as many contacts blocks 10 are provided as the perforated card hasfields, seven as shown by way of example in Fig. 2.
  • Each of the contact blocks 9 of the shaft 8 is, by means of a conductor 9 connected to one side of the related magnet171 of the accumulator 29 which, in the manner fully explained in Patent #1,617,088, controls the entries in the related elements 172 of the accumulator. Therefore, impulses are directed by conductors 9' to cause energization of such magnets 171, as the other sides of all magnets 171 are connected to the positive line side of battery B by a wire 171a and which common return wire 171a may be enclosed in the cable with the conductors 9', as shown in Fig. 1.
  • each accumulator wheel 17 2 is energized by electrical impulses as often as contact is established by means of the related brush 3 of the set which is in use entering a card hole.
  • Each of the brushes 3 of the set in use is, of course, as stated, in series connection with the related magnet 171 of the series.
  • each accumulator wheel is provided with a ratchet wheel 151 which is engaged by a pawl 161 connected to the armature of the associated electromagnet 171.
  • This pawl is suitably spring pressed to engage the ratchet wheel 151 and the usual retrograde preventing pivoted pawl 174 may be used to prevent backward turning of wheel 172.
  • the energization of magnet 171 causes the pawl 161 to be operated to such an extent that the ratchet wheel 151 is turned a distance of one tooth.
  • the transfer mechanism is fully explained in the British Patent #289,055 and as described briefly herein comprises a pawl 181 which is rocked clockwise when a wheel passes through zero thereby withdrawing its projection 182 from a projection 183 of a lever 184 which is thereby rocked so as to prepare a circuit to the next higher order -magnet to effect a transfer.
  • the brushes 3 and the contact blocks 10 carried by the cylinder may be plugged by employing any conventional plugging devices such as a plug So at the end of a conduc'tor 8' and a jack 8b which is electrically connected to the related one of the brushes 3.

  • One end of the spring 13 is secured to the shaft 8 and the other end to the casing 13 and the latter is held stationary with respect to shaft. 8.
  • This is preferably ell'ected by having integral ears 13a (Fig. 4) of the casing 13 receive a pair of stationary studs or rods 13?).
  • Each successive position of the shaft is maintained by a spring pressed pawl 14 cooperating with ratchet wheel 7.
  • Vhen the-magnet 19 is energized it rocks a double lever 17 pivoted by a rod 18.
  • Lever 17 carries two pins 16 and 15, the former disengaging pawl 14 from ratfhet wheel 7 and the latter disengaging paw 6' from ratchet wheel 7 and only when lever 17 is rocked.
  • pins 16 and 15 permit e11- gagement of pawls 14 and 6' with the ratchet wheel 7.
  • contact blocks 10 may be carried by a closed cylinder 7 so that after shaft 8 with the contact blocks 9 occupies its extreme rotated position it need not be returned to normal by a rotation in the opposite direction, but may be brought to the starting position by simply turning shaft '8 a step in the forward direction.
  • the conductors 9' between contact blocks 9 and magnets 171 of .the accumulator cannot, of course, be used as shown, and collector rings 9a are preferably provided on a cylinder which may constitute shaft 8.
  • contact blocks 9 are connected to collector rings Or; by conductors 9?) preferably within the cylinder which may constitute shaft 8. lVhen such a construction is employed the release mechanism comprising elements 15, 16, 17, 18, 19 are not necessary.
