  • Another object of the present invention is a printed circuit for the above combination, this circuit being quasiuniversal, that is capable of being adapted to each particular application by very slight modifications of its essential constitution while conserving its external contour and the general disposition.

  • studs are intended for the function of autoor selfrotation. Following stud 9, the circle is occupied by the ground area 30 which is connected to the output lug 31, intended for connection to ground. Between the different aforementioned studs (which will be referred to as rest studs), or between an extreme stud and the ground area, there are disposed intermediate studs such as 32, which will be referred to as work studs. These work studs are generally inactive, that is they are not connected to any electrical circuit, and they serve only to protect the insulating board 50 against the friction of the brush which would otherwise impair the insulation because of the sparks. However, only one of the work studs,
  • stud 33 located at 180 with respect to the work stud 34 that follows the rest stud 9 and precedes the ground area 30, is connected through a printed connection to the output lug 35 and is intended to function as a decade transfer stud, for purposes of transferring a pulse onto another analogous printed circuit.
  • This work stud 33 is located between two inactive studs 36, 37 that separate this work stud, on the one hand from the rest stud 20, and on the other, from the ground area 30.
  • a hole 44 is provided for the passage of the shaft of the ratchet wheel, to be described more fully hereinafter, which carries the brush, the arms of this brush sliding on the different studs or areas described above.
  • the brush 45 which is shown in FIG. 2, comprises four arms 46, 47, 48, 49, mutually shifted by 90.
  • This brush 45 is elastic and is made either from metal or plastic material, and the side thereof facing the board 50, is metallized.
  • the brush 45 is carried by the ratchet wheel 51 preferably also made from plastic material, which is shown in FIG. 3, representing a transverse cross section of the board 50.

  • Supported by the paddle is an armature of soft iron 56, intended to be attracted by the magnetic core of the coil 57, represented in dash lines.
  • the paddle 52 comprises a shaft 58 which is mobile in a bearing fixed to the housing of the device.
  • the armature 56 When the coil 57 is energized, the armature 56 is attracted thereto, and the paddle 52 slopes downward, turning on the shaft 58 in the clockwise direction. The tongue piece 55 then pushes or rotates the wheel 51 which advances by one step in the direction of the arrow. At this moment the arms of the brush 45 pass from a rest stud to a work stud of the printed circuit 50.
  • the armature 56 Upon de-energization of the coil 57, the armature 56 is released and the paddle comes back to the upper position under the action of the return spring 53.
  • the paddle 54 then pushes the wheel 51 in the same direction as previously, and the arms of the brush 45 pass from a work stud to the following rest stud.
  • the advancing of the wheel 51 is consequently effected in two stages, the first at the receipt of the pulse and the second upon cessation of the pulse.
  • the shaft 58 is placed laterally and the system of the tongue pieces 54, 55 operates with a double dissymmetrical release, the tongue piece 55 being at the extremity of a longer lever-arm than the tongue piece 54.

  • the box 60 is realized in such a manner that the different elements are fixed in their correct positions while the necessary pressure is exerted on the coil 57 against the board 50.
  • the wall opposite the board 50 supports the shaft bearings of the paddle 52 and the ratchet wheel 51.
  • FIG. 7 represents in perspective the obtained assembly, which forms an interchangeable unit or module. Placing such modules side by side and connecting them mechanically and electrically by suitable connections between the lugs of the boards 50 permits to achieve any desired multi-digit counter of which a few application examples will now be described.
  • This counter is supposed to be limited to three decimal digits, and for its realization three modules such as that of FIG. 7 are utilized. These modules are schematically represented in FIG. 8 by their printed circuits 50, 50', 50" intended for counting units, tens and hundreds, respectively, and interconnected as shown. These circuits are identical to that of FIG. 1 to which reference should be made for more details.
  • the indicator tube 61 is connected, in each module, to the studs 0 to 9 and 38.
  • the terminals 39 are connected to one pole - ⁇ -B of the power supply source of the tubes, the other pole of this source being connected to ground.
  • the terminals 31 are connected to ground.
  • the terminals 42 are connected to one pole +A of the power supply source of the coils 57, the other pole of this source being connected to ground.
  • the terminal 35 of the module of units 50 is connected to the terminal 43 of the module of tens 50', and likewise the terminal 35 0f the latter is connected to the terminal 43 of the module of hundreds 50".
  • the terminal 43 of the module of units 50 is connected to a pulse source, represented symbolically by a ground break switch 63, controlled by a cam wheel 64 in such a way that the terminal 43 of the module 50 is intermittently grounded.
  • This device operates as follows:
  • the coil 57 of the module 50 is energized by the circuit 42- 40-57-41-43, and the arm advances by one step passing from one rest stud to another.
  • the circuit of the indicator tube is consequently closed by one of the studs 0 to 9, the arms 46 and 48 or49, the area 30 and the ground terminal 31.
  • the successive numerals are indicated by the tube 61.
  • the arm 48 leaves the ground area 30 and passes during the first stage onto the work stud 33. But the arm 49 remains on the area 30 so that the ground is connected to the terminal 43 of the module 50' through the terminal 31 of module 50, the area 30, the arms 49 and 48, the stud 33 of the terminal 35 of the same module.
  • the module 50' which functions as a decade of tens, consequently begins to operates like the module 50 under the incidence of pulses.
  • the arm 48 leaves the stud 33, thus indicating the end of the pulse transmitted onto the module 50' where one of the brush arms then settles on one of the rest studs 0 to 9.
  • the arm 47 of the module 50 settles on the stud 0, this figure being then displayed by the tube.
  • At each quarter of a turn of the ratchet wheel there is a cyclical permutation between the functions of the different arms 46, 47, 48, 49, that is 40 pulses are counted during one turn of the wheel.
  • Resetting the counter to zero is effected by the use of the self-rotation studs 20 to 28. Indeed, when a module displays a numeral other than 0, the arm 47 rests on one of the studs 20 to 28 which are consequently grounded through the arms 47 and 48 or 49, the area 30 and the terminal 31. Pushing then the button 62 connects the ground to the terminals 43 of all the modules through the terminals 29 and the contacts of the switch 62.
  • the brushes of all the modules which are not at zero start advancing and owing to the two-stage advancing mechanism described above the ground circuit is alternately switched on and off so that while the button 62 is depressed, the coils 57 receive a series of pulses which cause the corresponding brushes to advance until the arm 47 settles on the stud causing the display of the corresponding numeral. At that moment the arm 48 settles on an inactive stud ahead of the stud 20 so that the circuit of the self-rotation studs 20 to 28 is cut off and the device stops at zero.
  • FIG. 9 represents a second example of application of the invention, namely to making clocks. Supposing that one wants to make a clock limited to the indication of minutes, use will be made of four modules whose printed circuits 65, 66, 67, 68 will be in their general form of the type of FIG. 1 with certain minor modifications dictated by the adaptation to the contemplated application.
  • the circuit 65 will work as a decade like the circuits 50, 50', 50" of the counter, but the self-rotation studs 20 to 28 have been removed therefrom since there is no need of resetting to zero in clocks.
  • the place of these studs is occupied by an extension of the ground area 30, and the transfer stud 33 has been advanced by 90 with respect to the circuit 50, that is it has been placed directly in front of the stud 0.
  • the circuit 66 intended to count the tens of minutes, has been additionally modified with respect to the circuit 65 in that the studs 0 to are the only ones connected to the corresponding cathodes of the indicator tube, while the studs 6, 7, 8, 9 are interconnected with each other and directly connected by a printed connection to the area 41.
  • This circuit is consequently a truncated decade in which the studs not utilized for the display will have the function of automatic self-rotation.
  • the circuit 67 has undergone additional modifications with respect to the circuit 65.
  • the ground area 30 has been cut into three sectors 69, 70, 71. Between the sectors 69 and 70, at 90 with respect to the studs 4, 5, 6, 7, 8, 9, is inserted a series of six interconnected plots or terminals 74 to 79, connected by a printed connection to an output lug 72. Between the sectors 70 and 71, at 180 with respect to the work stud located between the studs 3 and -4, is inserted a second transfer stud 73.
  • circuit 68 is modified as follows:
  • the cathode 0 of the indicator tube is connected to a small area 80 that occupies the position of the studs 0 and 1.
  • the cathode 1 is connected to another small area 81 occupying the position of the studs 2 and 3.
  • the cathode 2 is connected to the stud 4.
  • the stud 5 is left unconnected.

  • the ground area 30 has been cut into four sectors 82, 83, '84, 85.
  • a transfer stud '86 is inserted between the sectors 83 and 84 at 180 with respect to the work stud located between the studs 4 and 5.
  • a second transfer stud '87 is inserted at 90 with respect to the stud '86 between the sectors 82 and 83.
  • An empty work stud, at 180 with respect to the stud 8 7, is left between the sectors 84 and 85.
  • the studs 86 and 87 are connected to the terminal lugs 88 and 89, respectively.
  • the lug 88 is connected to the lug 43 of the module 67, and the lug 89 is connected to the lug 72 of the module 67.
  • the other connections leading to ground and to the supply sources +A and +B are the same as in FIG. 8.
  • an optional direct connection between the stud 43 on each module and the ground is established through the buttons which are intended for resetting the clock.
  • the module 65 working as a counter of minute units, is controlled once in a minute by a pulse supplied by the device 64 which symbolizes any mechanical or electrical clock mechanism. It functions like a decade which has been described in detail in connection with FIG. 8 so that these explanations need not be repeated.
  • the tube of this module displays cyclically the numerals 0 to 9.
  • the passage of an arm 46 or 47, or 48, or 49 onto the stud 33 releases a pulse on the terminal '43 of the module 66 which functions as a counter of tens of minutes. These tens are counted like in the ordinary decade until the number 5 is displayed by the tube, but thereafter, during the following pulse, the arm 46 passes onto the self-rotation stud 6, and the device starts advancing automatically by the same mechanism that has been explained in connection with resetting to zero the decades of FIG. 8 through the studs 20 to 28. After four steps forwards, the arm 47 reaches the stud 0, and the indicator tube consequently passes fro-m 5 to 0. Previously, the passage of the arm 47 onto the stud 33 releases a pulse on the terminal 43 of the module 67 which functions as a counter of hour units.
  • this module functions as an ordinary complete decade such as the module 65, except that the transfer pulse is transmitted onto the module 68 not only at the passage of the numeral 9 to the numeral 0 through the stud 33, but also at each passage of the numeral 3 to the numeral 4 through the stud 73.
  • one arm of the brush passes on the studs 74 to 79, but without incidence on the functioning of the module because these studs are connected through the terminals 72 to 89 to the stud 87 of the module 68, which stud 87 is connected to nothing during that period (from 0 to 20 hours).
  • one arm of the brush for example 46
  • the tube of the module 68 displays 0.
  • the pulse received at the passage from 3 to 4 hr. by the stud 73 of the module 67 causes the module 68 to advance, but the same arm then remains always on the same area 80, because this area covers two studs.
  • the pulse received by the stud 33 of the module 67 causes the arm 46 to pass onto the area 81, and the tube displays the numeral 1. This numeral is maintained from 10 hr. to 19 hr. 59 min. because the pulse received at the passage from 13 to 14 hr.

  • the arm 49 onto the stud 87
  • the arm 48 onto the stud 86
  • the arm 47 settles in the interval between the sectors 84 and 85.

  • the studs 74 to 79 function consequently by self-rotation through the mechanism that has been described previously, and the module 67 effects six steps forward until the arm 47 comes onto the stud causing the display of the corresponding numeral.
  • the module 67 transmits through the stud 33 to the module 68 a pulse that causes the arm 46 to pass onto the stud 6, and the arms 47, 48, 49 onto the ground sectors 85, 84, 83.
  • the studs 6 to 9 function by self-rotation until, after 4 steps forward, the arm 47 comes onto the stud 0, causing the display of the corresponding tube.
  • buttons 90 If one wants to reset the clock, for example after an interruption of the supply of the electrical masterpendulum, use is made of the buttons 90 by actuating them by pulses. Each pulse feeds individually the motor coil of the concerned module and causes it to advance by one step until the desired numeral is displayed.
  • a third example of application of the invention is concerned with a preselection counter, that is a counter on which a desired numeral is displayed and the counter is allowed to count the pulses.

  • the arm 47 arrives onto the stud 25, connected to the stud 4 of the keyboard 104, the stud 25 is found empty, and the device stops while the number 4 is displayed on the tube 61.
  • the device continues advancing stepby-step. After four pulses, the arm 46 leaves the stud 1 while the arm 49 leaves the area 102 and settles on the stud 33.
