Definitions

  • the object of the present invention is to design an apparatus by the aid of which connections may readily be established by easily accomplished adjustments.
  • my apparatus comprises in general a plurality of disks, one for each telephone connection or call, to be made. These disks are mounted firmly on a rotary shaft, driven by electricity or by clockwork, or otherwise.
  • the peripheries of lthe disks are provided with offset portions, cams or teeth, the lengths'of certain offset portions and their consecutive vorder corresponding to the digits and denominations of the telephone call number, to which the disk belongs, which hereinafter I term call-disk.
  • a slide is arranged to move parallel to the shaft of the disk and carries a yielding ngeradapted to contact with raised portions on the periphery on any disk, to which the slide may be adjusted.
  • a contact make and break device arranged in the telephone line is connected with the said slide and adapted to be operated when the yielding iinger contacts with the portions of the periphery of the'disk, to which the slide is adjusted; means being provided for impressingsignals on the electric circuit of the by interrupting the current ow, corresponding in number to the size of the sector Jof the raised portion.
  • the contact make and break device is mounted on the slide and may be ⁇ so constructed andy oiset" portions of the peripheries the ,disk rotating the teeth contacting with the yielding finger on the slide will directly transmit movements to the movable part of the contact make and break l necessary rapidity the desired interruptions of current, corresponding to the digits in question.
  • a lsecond contact telephone line make and break device is arranged in the telephone line, operated by suitable means, for instance by a clockwork to rapidly open and close the contact device without cessation. Raised portions on the periphery of the call disks, be-
  • the slide provided with the lyielding finger that contacts with raised portions on the call disks, instead of being conk nected with a contact make and break device, which in a regular manner periodically opens and closes the circuit, maybe connected with the contact make and break device operated by the clockwork or the like for enabling continuous interruptions in such manner, that the said vyielding finger is directly connected with the normally fixed, but in this instance yielding or pivoted contact piece of this contact device to pull this contact piece aside, when the circuit is to remain closed.
  • the construction may either be so designed that the yielding or pivoted contact piece is normally in a closed position, when the yielding finger on the slidev is engaged by outwardly oifset or such raised portions on the call disk, which correspond to thedigits of the call numbers.
  • This construction may be so improved, that said yielding or pivoted-contact piece is normally in operating position, and that the portion of the periphery of the call disks, that are attributed tothe digits of the call numbers, are offset inwardly instead of outwardly, as in previously described Yconstructions, so that the portions intermediate those which belong to the digits or call numbers, are now raised portions to operate on the yielding finger of the slide to transmit movement to the yielding contact piece to turn it aside. In both these instances the raised portions on the call disk act. as cams.

  • the disks e are provided with a number of offsets on their peripheries corresponding in number to the digits necessary for determining the local calls; thus for instance Hamburg requires 6k digits or signs, and therefore the disks are divided into 6 sections, each section having one offset f.
  • the length of the offset corresponds to one of the signs or digits from 1-0, thus the offset for zero will have to correspond in length to ten units and the offset for the smallest number 1 will have to correspond in length to one unit, that is to say 1% of that of zero.
  • the call D3,2492 would require offsets in length equal to 4, 3, 2, 4, 9, 2 units. W'hen thus the slide h is adjusted to a certain disk the tongue m will contact with the divers offsets f with interruptions in. lengths of time corresponding to 4, 3, 2, 4, 9, and 2 units of time during one revolution of the disks e.

  • the lengths of the offsets on the disk ecorrespond to a number 02,1417, and therefore there will be on the rotation of the disk ein consecutive order' 3, 2, 1, 4, 1, 7 interruptions in the telephone line, by which the telephone connection will be completed in the usual manner.
  • means may be provided for continuously causing interruptions' in the telephone line and provide for securing contact in the line in another way at times, when no interruptions are wanted.
  • FIG. 1 4 The construction shown in Figs. 1 4 is designed to fulfill this requirement.
  • a second contact make and break device is arranged within the telephone line L.
  • This-second contact breaker as shown in the drawings consistsof two yielding arms n, on each of which a contact piece n is mounted.

  • a segment p is firmly mounted on the shaft o and made of insulating material and adapted to enter between the ends of the arm n to break contact between the Contact pieces n' on rotation of the shaft o.
  • the ratio of the worm o', the worm gear o2 and the intermediate gear o3 is such that the shaft o is driven at a considerable speedto continuously break and make between the Contact pieces n' in rapid succession.
  • the tongue m has a contact piece m forming part of the contact make and break device m and m2; the contact piece m2 being attached to the slide h by an insulated block m3, to which also' is fastened the tongue m and which by the angle piece h is rmly attached to the slide h.
  • the contact make and break device m continuously keeps the circuit in the line L closed, no matterfwhether the contact make and break device n, n is opened or closed.
  • the contact make and break device m', m2 will open the circuit at this place, and the contact-make and break device n, n will take the necessary effect to secure interruptions according to the lengths of the offsets f, that is to say, according to the digits and the'consecutive order corresponding to the number of the telephone call. 4
  • the shaft o is connected with a regulator consisting of spring arms p provided with weights p2 at their ends adapted to contact with a fixed ring p3, when the shaft ois driven at a certain speed, thus regulating the speed of the insulated segment p.
  • any desired number of disks e may be mounted on the shaft d corresponding to the number of telephone calls, for which the apparatus may be constructed.
  • 15 different telephone connections may be made by the apparatus.
  • plates or panels 1c may be arranged on which the different telephone connections may be indicated constituting a staggered visual indicator.
  • Pointers k2 may be attached to the slide h for facilitating correct adjustment to the call disks, to which the panels correspond, which in order to save space are arrangedr in staggered relation as shown.
  • 'I'he gearing of the clockwork b may be so designed that the pinion o3 is continuously rotated to 'secure continuous interruptions of current by the contact make and break device n', n, p, n, n', and the .shaft ⁇ d must be driven by the clockwork through a. friction clutch to secure rotation of the disks e only when the shaft d is released. This is secured by a ratchet Wheel d firmly mounted on the shaft d, and having-only onetooth d2 adapted to be engaged by the pawl d3.
  • pawl d3 is pivoted to a pin d0 and engaged opposite the pin d by a spring-premed nger rod d5 projecting Yout through the cover of the casing and provided with finger piece d6.
  • VThe pawl d3 may be provided with a prolongation d4 adapted to engage a finger o4, when no call is made, the telephone line being in such .case closed by the contact make and break device m', m2 to allow the speech to be transmitted.
  • the slide h Will be adjusted by the handle i to thedisk e provided with o'sets f of the requisite lengths corresponding to the number of the call, and the finger piece operated by dpushed downward tolrelease the ratchet wheel d and the finger d4, whereupon the clockwork b rotates the divers mechanisms described above to make the telephone connection in question.
