' sage AUTOMATIC RECORDER FOR TELEPHONE-MESSAGES.

To all whom it may concern Be it known that I, HAROLD GORDON STALKER, a citizen of the Dominion of Canada, residing at Na'van, in the county of Russell, Province of Ontario, Canada, have invented certain new and useful Improvements in Automatic Recorders for Telephone-Messages, of which the following is a specification.

This invention relates to certain new imrovements or attachments used in connection with telephones, and the objects and nature of the invention will be readily understood by those skilled in the art, in the light of the following explanation, of the accompanying drawings illustrating one of the constructions or arrangements, embodying the fundamental principles of my invention.

The particular object of the invention is to provide a means by which a telephone meswill be automatically recorded, should there not be any person at the telephone to receive the message. The arrangement comprises .a case which is attached. to a recording-instrument in any desired manner suitable to the particular style of recording-instrument on which my invention is attached. In the accompanying drawings I have shown my invention as attached to the body of one style of a: recording-instrument, but I do not wish to be limited, in any way, to using my recording-instrument. 1s hlnged invention in connection with this particular recording-instrument, as by slight changes it can be arranged to be'connected to any recording instrument without departing from the spirit and scope of'this invention. The case is provided with a lever, having'an arm protruding through the top of thecase and having two branch arms extending and fitting over the regulating buttons of the One end of the lever on the side of the case while the otherend is fitted so as to be attracted by an electric magnet. Also, connected with the lever is another arm branching off from the side. at right angles to the other arm, and having its outer end so arranged to fit under the arm holding a telephone-receiver of a telephone, which sits on ashelf attached to the side of the case.

Specification of lLetters Patent.

designates Patented Feb. 29, 1916.

Application filed February 15, 1914. Serial No. 8,408.

The invention further comprises an attachment to connect on to the poles of the telephone-receiver. The Wires from this attachment run inside the case, connecting with a magnet, having-an armature which causes a connection of another circuit, coming from the connection in the recording-instrument, which acts on the magnet attract- 1ng the lever mentioned above and causes the same to be attracted. When this lever is attracted down the two arms on the top of the case press the buttons controlling the recording-instrument and put it in motion, and the telephone-receiver is also raised by action of the other arm and thus will allow the message to pass from the telephone-receiver through the receiver of the recordinginstrument and recorded on the disk or cylinder of the same. As soon as central cuts the connection off, the receiver will be restored to its normal position and the arms at the top of the case will come up, and thus take the pressure off the buttons on the recording-instrument and causes it to stop.

The invention consists in certain novel features in connection and combinations and arrangements as more fully and particularly out and are referred to in the following specification by the same numeral.

Figure 1 is a perspective view of the invention as attached to a particular recording-instrument. Fig. 2 is a view of the invention,

looking down on it with the top taken off. Fig. 3 is a section view of the plug or attachment connecting to the telephone-receiver. Fig. 4 is a cross-sectional view of the magnet switch.- Fig. 5 is a section view of the lever.

Referring to the drawings, in detail, 6 generally a recording-instrument, having a plate 7 in which the various keys 8, for regulating the recording instrument work.-

9 is a case attached to the recording-instrument 6 in anv desired manner but herein shown attached bv the screws 10.

11 is. a lever attached and hinged to the low.it to protrude a slight distance above side of the case 9 at 12 and having its opposite end 13 so arranged that it will be attracted by-the electric magnet 11.

15 is an arm rising perpendicular, from the lever 11, for a distance sufficient to althe top of the case 9 and then it branches off in two directions to have its end fit over the buttons 8, that regulate the recording.- instrument 6.

16 is another arm of the fulcrum 11. hinged at 17 and being mounted 0n the fulcrum 18. Arm 16 extends through the opening 19 and has its outer end 20 so shaped to fit under the arm 21 of the telephonereceiver 22 of a telephone 23 which sits on the shelf 21' and kept in position by the clamps 25.

26 is a plug or attachment, having connecting members 27 and 27", which connects with the two poles of the telephonereceiver 22. The connecting member 27* is provided with a spring 28 which causes the connecting-members 27 and 27 'to clamp the poles of the telephone-receiver 22 securely.

29 is a small plug in the side of the attachment 26 used to open the connectingmembers 27 and 27 in clamping them on the poles of the telephone-receiver 22. \Vires 38 connect with the inner ends of the connecting members and the armature 30 and the electric magnet 31. Said armature 30 has one end so provided with a circuit closer 32 so arranged as to make the connection of the wires and 31. The wire 31 comes from the circuit of the recording-instrument and wire 33 connects with the electric magnet- 11.

36 is a wire coming from the circuit of the recording-instrument 6 and connects with the end of the lever 11.

37 is a spring attached to the top of the case 9 and to the lever 11, and'holding the saidlever up.

39 is a set of wires running from the wires 38 to the shutter window 40. This shutter is of the ordinary style operated by a small magnet and operates the sign 41.

Now it will be seen that when central connects any other telephone with the one "using my invention, she will cause an electric current to pass through the wires of the telephone-receiver, which will go through the attachment 26 along the wires 38 to the magnet 31 and cause armature 30 to be drawn to the magnet. Vhen the armature is attracted. it will cause the connection of the wires 33 and 34:. Xow these wires will I cause action of the magnet 14 and will draw the end 13 of the lever 11 down, thus also bringing the arms 15 which will press down the keys 8 of the recording-instrument and set the instrument in motion. Also. the hinged end of the arm 16 at 17 will be pressed down thus causing the end 20 to go up, and as the end 20 is fitted under the telephone-receiver arm 21 when the end goes up, it will also cause the telephone-receiver 22 to be carried up. Now the connections are all made and the message will pass through the telephone-receiver 22, through the recording-instruments receiver -12 and be recorded tn the disk of cylinder of the recording-instrument. It will also be seen that the current will pass through the wires 39 connected to the wires 38, and cause the sign to drop.

X ow it will be seen that as soon as central closes off the connection, the magnet 31 will lose its power and the armature will go back to its normal position, thus cutting off the connection of the wires 33 and 31 and causing the lever 11 to be brought back to 3 its normal position by aid of the spring 37. This will release the keys 8 andthe motion of the recordirig-instrument will stop.

All that is necessary for a business man to do when he is'going away from his oifice and he desires to attach the recording-device to his telephone, is to set the telephone on the shelf 21, with the base under the clamps 25 and the arm 16 under the arm 21 of the telephone. Also, attach the plug attachine'nt 26 to the poles of the receiver 'hen he comes back it will at once be visibeen any calls made while he was out and if there has been any, they will be recorded on the disk or cylinder of the recordinginstrument and can be taken from there in the usual manner.

Now it is evident that various changes and modifications might be resorted to without departing from the spirit and scope of this invention and hence I do not wish to limit myself to the exact disclosure hereof.

Having thus described my invention, What I claim to be new is In a combination, a case, attached .to a recording-instrument, said case being provided'with a lever hinged at one side of said case and having arms branching off from the said lever, one of the said arms branching off and protruding through the top of the said case, said arm then so shaped as to fit over the buttons thatregulate. the recording-instrument, the other said arm branching off from-the said lever and extending through one side of the said case, one end of said arm being hinged to said lever, the other end of said arm being fitted so as to fit under the arm of a telephonerece'iver, said arm being mounted on a'fulcrum inside of said case, a magnet in said case so situated as to attract one end of said lever, a circuit therefor, said lever having a spring connecting with the top of the case, said case being further provided with a reble by looking at the shutter 40, if there have lay and an attachment plug, said plug connecting the poles of the telephone-receiver to respective wires which connectwith said relays inside said case, the armature of said relay when attracted causing the closing of said electric circuit to cause the said magnet to act on said lever, said case being further providedwith a shelf On which to set the telephone, and a shutter on one side connected .With the relay armature and 0perated thereby. v

In testimony whereof I aifix my signature in the presenceof two Witnesses.
