AUTOMATIC RINGING MECHANISM FOR TELEPHENE SYSTEMS.
Specification of Letters Patent.
Patented Dec. t9, rare.
Application filed August 80, 1913. Serial No. 787,533.
To all whom it may concern Be it known that I, CARwrr'r E. MYERS, a citizen of the United States, and a resident of Ironton, in the county oflron and State of Missouri, have invented a new and useful Improvement in Automatic Ringing Mechanisms for Telephone Systems, of which the following is a specification.
My invention relates to improvement in automatic ringing mechanism for telephone systems, consisting in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide a ringing mechanism for telephone lines, which is automatic to this extent, that when a ringing key is pushed, the device will serve. to effect certain current connections, for the sending of an alternating current to the sub-station, to efl'ect the ringing of the signal. t I 1 A further object of my. invention is to i provide a device of the type described,
which dispenses, with the necessity of using a constantly rotating generator for the ringing current at the sub-station, or for using batteries to keep inoperation theordinary pole changers.
A further object of my'invention IS tO provide an automatic ringing device which is in operation only during the time that the ringing is being done, thereby economizing in current and power.
Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended clanns.
My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a diagrammatic view showing the circuitconnections, Fig. 2 is a side view of the vibrator, Fig. 3 is a lan View ofthe vibrator shown in Fig. 2, i'g. 4 is a face view of a relay, and Fig. 5 is a side view of the relay shown in Fig. 4.
Referring now to Figs. 2 and 3, I have shown therein a vibrator which consists of a base 40, upon which is mounted a standard 41 bearing the magnets G. The latter has an armature P which is disposed on the vibrator arm E, pivotally. mounted at K and bearing an adjustable weight S on one end. The opposite end of the vibrator E is provided with a contact K arranged to engage an adjustable contact screw K Secured to the armature P is an arm 1? bearscrew L and at the other to the armature P Secured to the vibrator arm is a cross member S, the ends of which-are slotted to permit the entrance of spring arms G and G. The former is carried by a bindingpost 31 borne by a support 31*, and the latter by a binding post 31 ona support 31 Each of the armsG and G is provided with a platinum contact near its central part. The platinum contact borne by the arm G is arranged to engage the terminals 5 and b of the contact screws B and Brespectively mounted on supports B", and B respectively, while the platinum contact on the upper arm G is arranged to engage the contacts 12 and b on the contact screws B and B", respectively which are carried on supports B and B similar to those shown at B and B It is obvious that when the arm E moves downwardly the lower contacts will be engaged, but when it moves upwardly the upper contacts will be engaged. Referring now particularly to Figs. 4 and 5, I have shown therein magnets F whose armature F is carried by an arm 3 pivotally mounted at G on a support G and provided with a contact-y arranged to'engage acontact y carried on a support G. The
system is that in ordinary use and constitutes- 1 no part of my invention, except in so far as it cooperates with the apparatus just described. The description of the rest of the system and of the arrangement for automatic ringing will best be understood by taking a specific example of the operation of the device. I Y
' Let us consider now Fig. 1. (1, represents a ringing key which, when ressed, serves to connect a circuit from the attery- X at the left of the figure, thiscircuit being as follows: from battery X over wire 3 to terminal R thence through wire 3, contact spring Gr, platinum point w, b (the contacts to and w being held against the upper contacts b and b by the tension of the spring 1L) wire 6, wire 6, coil F, wire 6, terminal lit, wire 1,
ringing key a, through the switch board cord a, plugging jack a and then through the line 1*, through the windings n of the subscribers station u, the1i back through the wire 2 to the plugging jack a cord a,to the ringing key a, thence through wire 2 to the terminal R, wire 5?, terminal I), contact w, arm G, wire 4:, relay R wire 4, to battery. The circuit just traced is called for purposes of convenience, circuit No. 1. At the instant that the ringing key a is pressed, which closes the circuit just described, the magnet F will be energized, thereby pulling down the armature F and closing the contacts 3 y. This causes current to flow from the vibrator battery X to the binding post R wire 8,contact 3 contact terminal y ,terminal 8 to vibrator standard K vibrator arm E, contact spring P, platinum points I, I, P, wire 10, to the windings-of the magnets C, wire 9, to terminal R and thenceto battery X. For convenience I have termed this circuit No. 2.
The energization of the magnets causes the armature p to be pulled downwardly,
but through the medium of the cross arm S which is carried by the vibrator arm E, contacts w and w are shifted from the upper contacts I) and b to the lower contacts 6 and 6 respectively. The shifting of these contacts causes the relay F to become deenergized, thereby breaking the circuit through the coil C. The adjustable screw.
K touches K on a spring 'K carried by the arm E. This closes the vibrator clrcuit again over thebattery X, binding post R wire v9, terminal K contactK, contact K, arm E, P contacts I, 1, wire 10, coil C, wire 9 binding post R At the instant that circuit No. 2 above described is closed, the movement of the armatacts to the upper, causes a change of ture P causes the breaking of the circuit of are involved and that when the vibrator arm E isup, current will flow in one direction,- and when it is down, it will How in another.
direction.
It will be seen that I have provided a device by means of which current is supplied to the terminals for ringing the si al to telephone the sub-station only at suc times as the ringin is actuall being done. At other times t e current 1s being conserved and this, as stated before, obviates the necesaaoesrs sity of. employing constantly rotating gen erators or batteries, which keep in operatlon the ordinary pole changers.
The device is simple in o eration and is not liable to easily get out 0 order.
