Definitions

  • This invention relates to apparatus for making calls with rapidity in automatic telephony.
  • the present invention has for its object an apparatus of the kind above described which is characterized firstly in that to the rows of discs are substituted an equal number of solid cylinders provided around their circumference with lines of bosses arranged in steps according to length in a number equal to that of the call signals they are designed to compose or, in other words, to the number of groups of interruptions they are designed to produce, (say 60 lines of bosses for the first cylinder if there are 60 sta tions to supply and 100 lines of bosses for the number cylinders) these lines of bosses all begin ning at the same generatrix and comprising each a suitable number of bosses divided from one another by intervals of the same value each of a length suited to the letter or the digit which it must form.
  • Another feature of this invention consists in 55 theprovision for connecting every cylinder with the general movement of the apparatus of a gear mechanism combined with the bosses of the preceding cylinder in such a manner that the considered cylinder begins to move as soon as the last boss upon the preceding cylinder has 5 completed its operation.
  • the last boss of each line of bosses in every cylinder is provided at its end with a projection in the path of which a lever pivoted upon the frame of the corresponding short circuit switch is mounted, said lever being designed to actuate, when it is moved by said projection, the locking element of a pawl integral with the cylinder following the considered cylinder and thus allow said pawl to engage in a'rotary ratchet wheel designed for driving said cylinder, with the result that as soon as one cylinder has ended its operation-- without having completed its rotation-the fol lowing cylinder begins to turn and consequently there is no delay in the sending of the current interruptions in the line from one cylinder to the other.
  • Another feature of this invention consists in the arrangement of a contact for short circuiting 5 the microphone and: the receiver during the sending of current interruptions, one blade of said contact being engaged with a hook integral with a locking device of the general movement so that the unlocking stroke of said device causes through a pull upon said hook the closing of the contact, a mechanism provided at its end with a lever arm being placed in the path of the end projections of the last bosses upon the last cylinder, said mechanism when inoperative being 5 positioned under the aforesaid hook so that as soon as the last cylinder has ended its operation relatively to the corresponding short circuit switch, said arm lifts the hook and thus allows the blade to open the contact through the efiect of its elasticity, consequently putting again the microphone and the receiver incircuit.
  • FIGS. 1 and 2 are respectively a developed plan view illustrating respectively the cylinder designed to form the call signal of the station to be :connected and a cylinder designed to form a pair of digits, the indications upon said figure being in fact inscribed upon an index plate placed above the cylinders.
  • Fig. 3 is a plan view illustrating the general arrangement of the mechanism and of the cylinders (the short circuit switches being excepted).
  • Fig. 4. is a front elevation showing the driving gears diagrammatically.
  • Fig. 5 is a corresponding developed plan view.
  • Fig. 6 is an elevation of the mechanism used for the successive driving of the cylinders.
  • Fig. 7 is a corresponding part plan View.
  • Fig. 8 illustrates the locking mechanism of the movement, and driving mechanism of the interrupter used for short circuiting the microphone and the receiver.
  • Fig. 9 is a front view of a short circuit switch.
  • Fig. 10 is the diagram of the connections.
  • the apparatus shown (in Figs. 3, 4 and 5) comprises a clockwork motor IOI whose shaft I02 carries on the exterior a handle I03 and on its inner side a pinion I04.
  • the pinion I04 slides under apawl I05 integral with a main wheel I06 so that as soon as the handle has been released, it rises and the shaft I02 with the pinion I04 rotate in the opposite direction, the wheel I06 being drawn along in the rotary movement.
  • the wheel I06 drives a pinion I01 integral with a wheel I 08 which in its turn drives another pinion I09 secured upon a middle shaft H0.
  • the latter drives, by means of appropriate gears, another shaft III supporting a cam or interrupter I I2 arranged to open a contact I I3I I4 twice at every turn, the rotation of said cam being regulated by a speed regulator of any suitable kind II5.
  • the shaft I I0 is extended in order to constitute an axis of rotation for the middle cylinder of the hundreds H6 and it carries a wheel II1 which by the intermediary of pinions H8, H9 causes the rotation in the same direction of two other wheels I20, I2I with their shafts I22, I23 forming the axes of rotation for the cylinders II6 II6 of the call signal and of the units respectively.
  • the shafts I22, IIO, I23 carry ratchet wheels I36, I31, I38 which will rotate permanently as soon as the discs I24, I25, I26 are unlocked.
  • ratchet wheels I36, I31, I38 which will rotate permanently as soon as the discs I24, I25, I26 are unlocked.
  • the clockwork motor shaft I02 there is provided upon the clockwork motor shaft I02 a cam I39 whose projecting part I 39 pushes back the pawl I21 when the hand lever I03 is depressed and thus unlocks the whole system.
  • a pivoted pawl I44 I44, I48 designed to transmit the movements of the ratchet wheels I36, I31, I38 to said cylinders.
  • the tail I45 of the first pawl I44 is locked by the wall I46 of a lever I41 pivoted upon a stationary part I48 of the apparatus frame, so that the hook on the pawl is out of engagement with the ratchet wheel I 30.
  • the lever I421 is provided on the other hand with an arm I49 which when in the aforesaid inoperative position engages a notch I50 in cylinder II6 and locks the latter, and with a second arm I5I which may be moved second projection I39 of the cam I39 when the handle I03 which drives said cam through the shaft I02 is depressed.
  • the projection I 39 of the cam I39 which begins to 1'0- tate in the opposite direction as soon as the hand lever I03 is released is suitably shaped to free the arm I5I at about of its own return stroke, that is to say when the first cylinder has made a revolution in such a manner that the cylinder is again looked after a complete revolution.
  • the first one H6 (station call signal) comprises (Fig. 1) as many lines of bosses as there are telephone stations to supply. Considering that in the example which has been selected every station is designated by interval, the same as in the cylinder H6 In this case also all the first bosses start from the same generatrix I58.
  • Three runners I59 I592 I56 which may be brought above the selected line of bosses are slidingly mounted over the three cylinders. For this purpose said runners are provided with indexes I66 and guiding marks, directions (letters and numbers) being traced upon a horizontal plate I6I arranged at the top of the apparatus.
  • the runners are each provided with a short circuit switch consisting of two blades I62, I63, which frictionally engage twoblades I64, I65 and when inoperative are electrically connected together.
  • One of said blades is integral with an insulated finger I66 I66, I66, which when engaging the bosses of the corresponding rotary cylinder breaks the contact between these two blades.
  • the lever I61 of the first runner presses back a bar I66 integral with another lever I10 pivoted at I1I in such a manner that a pawl I12 carried by said lever I16 which was engaged in a notch I14 of the second cylinder II6 comes out of said notch and frees said cylinder, and that a boss I15 of the same lever I16 frees the tail I45 of pawl IN and allows the latter to engage the ratchet wheel I31 and consequently to cause the displacement of the cylinder I IIS It will therefore be seen that as soon as the last boss in a line in the first cylinder has come under the short circuit switch which co-operates with said cylinder, the second cylinder starts and begins its operation.
  • the hanging lever I61 of the second runner fills the same office, by similar means with regard tothe third cylinder so that the latter begins to rotate as soon as the second cylinder has ended its effective function.
  • a branch circuit passing through the contacts c--c (1-11 of the junction P is provided for short circuiting the microphone M and the receiver R, said branch circuit may be closed by means of a contact consisting of two blades of which the one I16 is divided from the other through the effect of an initial voltage (Fig. 8). in the required direction for producing the contact by means of a hook I18 pivoted at the end of the looking lever I29 of disc I26.
  • Said hook is pressed in the required locking direction by a spring I19 but may be raised by a finger I80 integral with a lever I6I pivoted at I82, integral itself with a bar I 83 which may be actuated by a lever I61 of the third runner I59.
  • each cylinder having an exterior surface provided with. a plurality of elongated embossings, a plurality of projecting members, a separate one of said projecting members being situated at an end of each of said embossings, a plurality of levers, each of said levers being adapted to be moved by some of said projecting members, a plurality of other levers, each of the second-mentioned levers being adapted to be moved by a separate one of the first-mentioned levers, mechanical clutching and disengaging means adapted to be actuated by the second-mentioned levers to cause one of said cylinders to begin its rotation as soon as the rotation of another one of said cylinders has been terminated, a plurality of switches, the number of said switches being equal to that of said cylinders, a separate one of the first-mentioned levers being pivotally mounted on'a separate one of said switches, and means
  • This blade I16 may be drawn
