ANSWERING AND RECORDING TELEPHONE.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed March 22, 1913. Serial No. 756,173.

To all whom it may concern:

Be it-known'that I, CARL J. GUSTAFSON, a citizen of the United States, resident of Aberdeen, Brown county, South Dakota, have invented certain new and useful Improvements in Answering and Recording Telephones, of which the following is a L specification.

My invention relates to that class of instruments for use in aresidence or oflice wherein provision is made for. repeating a certain predetermined message in answer to a call on the line and also recording any message which the person on the line may choose to dictate.

The object of my invention is to. simplify and improve answering and recording telephones of this type and provide a machine which will be positive in its action, will accurately repeat a certain message to the person. calling, and record several messages which from time to time may be dictated frpm the line when the user of the instrument is absent.

Other objects of the invention will appear from the following detailed description.

My invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of the specification, Figure 1 is a diagrammatic view, illustrating the various circuits embodied in my apparatus, Fig. 2 is a plain view of thetransmitting and recording devices, Fig. 3 is a transverse sectional view of the same, taken on the line y-y of Fig. 2, Fig. 4: is afront view illustrating the transmitter operating mechanism and the screw for returning thetransmitter to its normal position, Fig. 5 is a sectional view on the line :v-w of Fig. 4, Fig. 6 is a view similar to Fig. 5, showing the mechanism in operation for returning the transmitter to its normal position, Fig. 7 is a perspective view illustrating the mechanism for releasing the motor to o erate the transmitting and recording mec anism.

In the drawing, referring to Fig. 1, 2 represents a suitable casing, 1n which the apparatus is mounted. This apparatuscorresponds substantially to that used in an ordinary phonograph, with various additions and modifications to adapt it for the purposes of my invention. A plate 3-is mounted in this casing and provided with depending brackets 4 supporting a frame 5 wherein the operating spring is arranged. A shaft 6 is geared to this spring and is adapted. to receive a winding crank. The shaft of the drum is connected by suitable gearing 7 with a pulley 8 and a governor 9, all substantially as found in an ordinary phono-- graphic machine. The pulley 8 is connected by a driven belt 9 with a pulley 10 on a screw shaft 11 that is mounted in a frame 12 above the plate 3 and carries at one end a recording cylinder 13 which is adapted to record the message from the person on the line. This shaft 11 is connected through suitable gearing 14 with screw shafts 15 and 16, the frame carrying a recording cylinder 17 hearing the message which it is desired to repeat to the person on the line. A guide rod 18 is mounted on the frame 12 and provided with a carriage 19 adapted to support one end of a transmitter 20, the lower end of which is supported by a guide 21. An arm 22 is mounted on the carriage '19 and adapted to bear on the screw shaft 15 and be fed thereby with the carriage 19 and the transmitter lengthwise of the cylinder 17 the transmitter reproducing the message on the cylinder to the person on the line, as will hereinafter appear.

At the lower end of the arm 22 is a yoke 23 pivoted at 24: on saidarm and having a lower end that is adapted to engage the screw 16 which is mounted to revolve in the opposite direction from the screw 15. The yoke 23'has a pin 25 adapted to slide in a slot 26 in the lower portion of the arm and limited in its movement by the length of said slot, and a weight 27 is carried by. said yoke and is adapted to swing the yoke into engagement with the threads ofv the screw 16 when the arm 22 is raised sufficiently to allow the yoketo clear the top of the screw. (See Figs. 5. and 6.) This lifting of the arm is. accomplished by means of a pin 28 carried by a bracket 29 at the end of the screw 15, the engagement of the pin with the arm operating to liftthe said arm out of enagain when another call comes in. The mesrod 30 having a carriage 31 provided withan arm 32 which engages the threads. of the screw 11. A receiver 33 is connected with said carriage and is arranged to move over the cylinder 13 and record the message thereon that comes in over the line. This carriage 31 will be set in motion simultaneously with the carriage 19, and the receiver 33 will be in operation to receive and record the message on the cylinder 13 as soon as the person on the line begins to make a response to the message received from the cylinder 17.

'The operation of the motor is controlled by a brake device illustrated in detail in Fig. 7, consisting of a disk 34, a strap 35 connected through a crank device 36 with an arm 37 on arock shaft 38. A spring 39 is mounted on said rock shaft and normally tends to hold said shaft and the'mechanism controlling the strap 35 in their locking position. A pair of electro-magnets 40 is provided near the shaft 38 and an armature 41 is mounted on a rack bar 42 having its teeth in engagement with a pinion 43 on the shaft 38. When the electric circuit is closed through the magnets 40, the armature 41 will be attracted to move the bar 42 lengthwise and rock the shaft 38 a limited distance. The bar 42 has a guide 44' and a notch 45 adapted .to receive a rod 46 which is vertically slidable in. a guide 47 and is normally held in its raised position by a spring 48. This rod upon entering the notch 45 looks the rack bar 42 temporarily and prevents the release and return of the shaft 38 to its normal position until the mechanism has traveled a predetermined distance. This tripping of the rod 46 I prefer to accomplish by means of a lug 49 mounted on the periphery of the drum 5 in position to engage an arm 50 pivoted at one end and engaging at its other end the lower end ofthe rod 46. This lug may, of course, be placed in any'suitable position on the drum to properly time the operation of the rod 46 and the release of the rock shaft. The recordin cylinder is preferably of suitable length to adapt it for recording several messages which may be dictated to the machine in the absence of the operator, the length of each message depending upon the position of the tripping mechanism with respect to the rod 46. Obviously in the construction shown, the longer the travel of the actuating lug 49 before it trips the rod 46,. the greater the time of operation of the machine and the length of the message whichmay be recorded on the recording cylinder. An arm 51 is mounted on the shaft 38 in position to normally engage a switch W which, when the shaft is released, will close an electric circuit, as will hereinafter appear.

The operation of the mechanism heretofore described will be controlled through the energizing of the electro-magnets 40, and I will now describe in detail the various electric circuits which I employ in connection with the apparatus for the automatic sending and receiving of messages.

The bell circuit, or the one that is closed through the use of an instrument on the line, comprises the line wire A to the terminal B, the conductor C to call bell D and conductor E, from call bell back to terminal F and return line-wire G.

The relay circuit includes conductors A and C, conductor H and relay I and conductor J and conductors E and G.

The motor circuit includes relay I to switch L, (which is set to close the circuit when the operator leaves the ofiice and it is desired to have the instrument send and receive a message) from switch L to conductor M through battery N and conductor 0 to the electro-magnets 40 and return through conductor Q to relay I.

The transmitter circuit primary is through battery N, conductor R to transmitter S and through conductor T to post on switch hook U and conductor V to switch W, through switch VV to conductor X to switch hook post U and conductor Y to the primary coil in induction coil Z, and from thence through conductor Z to battery N.

The secondary transmitter circuit is through conductor A, terminal B and conductor B to the secondary winding of induction coil Z, thence'to conductors Y and X, switch W, conductor W to receiver S, and from thence through conductor T to condenser E, terminal F and line conductor G.'

The receiver circuit includes line wire A to terminal B and conductor B, to the secondary winding of induction coil Z and conductor Y, and conductor X to switch W, from thence through conductor W, receiver S, and conductor T to condenser E, terminal F and return line wire G. There is also provided in connection with the induction coil Z a generator Z of ordinary construction, usually found in connection with circuits of this description and which needs no detailed illustration or description herein, as I make no claim thereto.

In connection with the switch hook U I provide the usual receiver U by means of which the operator can use the instrument as a telephone in the usual way, the appa' 'circuit being closed at the switch hook U upon the removal of the receiver from its supporting hook. If the person having the apparatus in his ofiice or residence wishes to be absent for a time and there is no one to take or give a message to any one calling, he will set the switch L and if a person closes the bell circuit from somewhere on the line the magnets 40 will be energized through the circuits described and the mo-. tor released and the transmitter 20 will immediately begin to move over the cylinder 17 and the message thereon will be repeated to the line, such message usually stating that the person called is out-and requesting that the person calling give a message which may be repeated when the owner of the instrument returns. This being received by the person on the line, he will give his message, which will be recorded on the cylinder 13 'so that when the person called returns he may reproduce this message and understand that such and such a person called him and at the same time obtain a complete reproduction or the substance of the message to be communicated. Sometimes the person calling may communicate his complete message or may simply cause to have recorded on the cylinder 13 the fact that such and such a erson called and asking that the owner 0 the instru ment communicate with him upon returning to the ofiice.

The checking of movement of the operating mechanism may be timed or regulated to allow a long message from one person to be recorded, or a series of short messages from different persons calling the office during the absence of the person called.
