MOTOR TO CONTROL AUTOMATICALLY A SUBSCRIBER/S TELEPHONE FOR VARIED SERVICE.

Specification of Letters Patent. Patented Sept. 19, 1916,

Application filed October 5, 1915. Serial No. 54,138.

To all whom it may concern:

Be it known that I, EDWIN V. M. BRnN- NAN, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Motors to Control Automatically a Subscribers Telephone for Varied Service, of which the following is a specification.

My invention relates to a motor to establish and control automatically a telephone circuit from a subscribers telephone through a central station with another telephone for intercommunication, recording a call, to light and extinguish lights at distant points by telephone connection, to register predetermined calls of different subscribers telephones on the operated telephone, as well as phonographically calls through the subscribers telephone actuated and controlled by the motor set in action by a rolling contact actuated by the clapper of a central station circuit bell to establish the circuit of the subscribers telephone through the central station with the telephone in which required connection is desired.

My invention in such connection relates to the general structural arrangement of the motor and accessories adapted to be brought into relation therewith and operated thereby and to the automatic operation of the motor for bringing the subscribers instrument into and out of circuit through the central station with the particular subscribers telephone desired for certain or all of the defined purposes.

The nature, scope and characteristic features of my present invention will be more fully'understood-from the following description taken in connection with the accompanying drawings, forming part hereof, in which Figure 1, is a diagrammatic View of a 2, is a front elevational View of the motor, showing the same in engagement with the receiver-arm of the subscribers telephone. Fig. 3, is a plan view of Fig. 2. Fig. 4;, is a vertical sectional view through the casing of the motor, showing the operating mechanism and registering device operated by the motor and a timing device' shown in broken section. Fig. 5, is a detail View of an adjustable cushioned saddle adapted to be brought up against the receiver-arm'of the telephone in lifting the same by the action of the motor. Fig. 6, is a view partly in section and partly in front elevation, a modified form, in this instance a double rolling contact arranged to be actuated either way by the clapper of a central station bell; and Fig. 7, is a transverse section on the line a", w, of Fig. 6, showing a means to angularly adjust the casing as the movable contacts shift with respect to each other and as operated by the vibrations of the bell clapper, for example in the manner as shown in Fig. 6.

Referring to the drawings a, represents the motor mounted in a casing a. The shaft a of the motor carries a pinion a meshing with a large gear-wheel a This gear-wheel carried on a cross-shaft a has fixed thereto a cam a, for controlling the up and down movements of a long leverarm a arranged lengthwise of the casing a and pivoted at one end in the said casing thereto and carrying at the free end thereof and beyond the said casing, a. padded saddle a adjustably supported in required position by means of a tightening nut a In the casing a, as shown in Fig. 4, is arranged an adjustable contact a so that by the lifting of the said lever-arm a, in a manner to be hereinafter more fully explained positive contact is established with said arm. In the casing a is also mounted any well known type of registering device a, the movement of the lever-arm a, shift ing the numeralsof the same, so that any call of the telephone may thus at once he observed through the opening in the face of the said device at the subscribers telephone. Mounted on the shaft o is a phonograph disk a", with .a reproducer a, and a horn a, which may be brought into the path of the transmitter b of the telephone, for example, as clearly shown in Figs. 2 and 3. This telephone is provided with a receiver 6 and forked arm 6 engaging the same which is adapted to be brought into contact with the cushioned saddle a, for placing the receiver thereby in a position to be automatically lifted by the motor a, in a manner to be hereinafter more fully explained.

c, is a lighting system, showing the generator 0 and a switch 0 with a chain 0 connected with one terminal of said switch, for operating the same. The chain 0 is adapted to engage a hook a, of the leverarm a", operated by the motor a, as clearly shown in Fig. 1.

The foregoing isone of the applications in which the motor a, can be employed in conjunction with a telephone system, to control automatically the making and breaking of connection between subscribers telephones through a central station exchange,

' not shown, and in which also the lighting and the extinguishing of lamps of a, plant can be controlled thereby at predetermined times by the use of the timing device d, controlled through the said motor a, by the operation of a subscribers telephone in circuit with said motor as will be hereinafter more fully explained.

Adjacent to the bell-box e, in the circuit of the central station exchange, not shown, is provideda clapper 6 for tapping the bell or bells e thereof, as clearly shown in Figs. 1 and 6. In close proximity to the clapper 6 is arranged pivotally supported, a tube 0 Fig. 1, with internal track-ways e, e, suitably insulated from the said tube for the reception of a ball or balls 0 as clearly shown in Figs. 1 and 6. The ball normally rests in one extremity of the tube, beyond the track-ways provided therein. The vibration of the clapper e drives the ball 6 from its normal position onto the trackway '6 e, to thereby establish a circuit by the lines 10, 11, from the source of energy 12 and line 13, to the positive contact a and by a branch line 14 to the timing device 11,

land by the line 15, to the lever-arm a and by the line 11 to the motor a, and by the line 16, to the binding post 03 of the said timing device d. The timing device (1, "consists of a series of 12 separate or distinct sectional insulated. cont-acts d as clearly illustrated in Fig. 1. This device is provided with plugs (Z in the series of sections d This timing device 'd, is provided with hands d d operatively controlled by a suitable clock-work mechanism, not shown. The arrangement of this timing device provided with the plugs LP, is such as that at predetermined different hours the subscribers telephone can be actuated to establish automatically through the central station exchange communication with some other subscribers telephone or telephones or failure to establish such connection and of that fact being known by the exposure of a certain numeral in the opening of said registering device a.

In establishing a circuit through the telephone, the exchange bell call is actuated to cause the clapper e and it in turn to drive the ball 6 onto the trackways 6, 6 of the adjustable tube 6 so as thereby to establish the circuit 10 and 11, and branches thereof, to and through the motor a, to cause it to be set inaction and in turn the longitudinal lever arm a, to be brought into engagement with the contact a, when the ball 0 by this time, will by gravity fall back into the extreme end of the tube 6 for example, into the position as shown in Fig. 1. The contact being established as just described, the motor continues to operate until the telephone receiver forked arm is lifted to establish intercommunication of such telephone through the exchange with any other particular subscribers telephone desired, or the fact it cannot be had by reason of being busy or not answering, which will be registered on the device a, through lifting of the said lever-arm a. It can be so arranged as shown, so that the phonograph by having recorded the call, will when the telephone is again operated call this particular number of the telephone that was desiredv or that could not be had and the fact given through the transmitter of said subscribers telephone. By placing the chain 0 in engagement with the hook a. of the lever-arm (1., and plugging in on the timing device d, the particular hour to light or extinguish a lamp or lamps of a distant lighting plant, in the automatic operation of the telephone receiver, by the motor a, can be readily accomplished. The plug being arranged in the branch circuit 14, from the source of energy for this purpose, as will be readily understood from Fig. 1.

The important feature of my said invention is to automatically connect up the receiver-arm of a telephone with a motor to enable when the oflice force is absent to permit a person to call that telephone and to have the call register or to phonographically record the same so that in again 0 erating the telephone the call will be t en given to the operator or through the registering device, the call noticeable by the change of numeral exposed through the face of the said device a. It can also be employed equally well for the switching in of the lamps of a distant lighting plant by the action of the said timing device operating in conjunction with the said motor to raise the receiver-arm so as to establish automatically the circuit at some predetermined hour' or moment of time. Each subscribers telephone it is to be understood must be provided with such a motor for the defined purpose.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is 1. In a motor of the character described,
