Bait-known that .1, JOHN C. Lows, acitizen ofthe UnitedStates, residing at Minot,

inthe county QflVard' and State of North 'iDakotadhave invented certain new and useful '-'Improvements in Combined Phono-v graphs andTelephonea'of whi'ch'the follow- My inventiomrelates to improvements in combined 'phonographs and telephones.

a My. invention embodies the combination of a phonograph with a telephone, by means of which a telephone call is automatically answered by the machine at the station returns'tot'he starting position, and stops,

called, after which operation the machine and is in a condition to repeat, the opera-- tion, atevery subsequent call ofthe telephone. The invention enables the answering got the telephone calls automatically in the I; absence of anyone at the station called, by placing upon the machine; a phonograph record, having thereon-a desired message to bodying my invention, I

Figure-6 is an enlarged side elevation of the sound box, and associated elements. In the drawings, whereinfor the purpose of" illustrationis" shown a preferred 'embodiment of- Iny'invention, the numeral 10 designates abox or casing, within. which is mounted a motor, such as a springmotor or van electric motor, driving a train of gears 11. These gears are connected with a brake I disk 12,"rotating therewith. When the brake disk is held against rotation, the train of gears. do not rotate. I I Arranged above the casing 10 is a hori- 'zontal. rotatable cylinder 13, receiving its rotation from a shaft 14', having a pulley 15 rigidly mounted thereon. This pulley is drivenf by a lieltddengaging a pulley 17,

The shafts 18 and 19 are screw threaded throughout sub- ,stantially their entire length, asshown. Theshaft 18 receives its rotation from a gear 22, rigidly mounted thereon and this gear en gages a gear'23 r1'g1dly mounted upon the shaft 19, and it is thus seen that the shafts 'the guidesh-aft- 26 is a carriage 28, which cannot turn thereon, by virtue of a key 29, slidable in a :slot 30. The carriage 28 rigidly supports, an overhanging arm 31, carrying the diaphragm chamber or sound box 32.

The diaphragm chanibier' receives the usual diaphragm, having suitable connection with thestylus lever 33, which is vertically adj'usted and carries the stylus 34. The stylus lever is raised and lowered by means ,of a" bell-crank lever pivoted at 36, to abracket 37, rigidly secured to the arm 31. This bell-crank lever is connected with a link 38,

which is shiftedby means to next .de-'

scribed."

v The carriage 28 has a tubular extension or hub 39, rigidly secured thereto, and this tubu- I lar extension pivotally receives a collar 40 formed upon the central portion of a feed bar 41. Thisfeed .bar is provided at its ends a with curvedh'eads 4:2 and 43, having screw threaded recesses dfwhich engage the feed and reverse shafts 18 19, as shown. The collar 40 is provided in its top with a spring.

pressed bolt 45, for, insertion within reclearly shown in Figure5. An upstanding inverted ll-shaped frame 48 is rigid y mounted upon the feed bar ,41, and projects above the same, and is pivotally connected with the link 38, as shown at 49.

inagnet 50 arranged within the box 10, and

electro-magnet 50, and is retained in the normal position by a spring 52. The armature 51 Carries a spring pressed pawl 53, engaging a horizontally rotatable ratchet wheel 54, having teeth for more than onehalt' of its circumference, while the remainder is smooth. This ratchet wheel is rigidly mounted upon a vertical rotatable shaft 55, projecting above the box 10, and hav-' mg a horizontally arranged cam 56 rigidly mounted thereon. The ratchet wheel 54, Figure 4, -has a link 57, arranged there-beneath, and pivoted thereto, and this link is pivotally connected with a slide rod 58, op-- erat-ing'within a guide 59. The slide rod 58 carries a compressible brake shoe 60, to engage and disengage the brake disk 12.

The numeral 61 designates a stationary shifting'cam, arranged near one end of the shafts 18 and19, and 62 designates a second stationary shifting cam, arranged near the opposite end of the shafts 18 and 19. These cams have upper inclined faces 63. The

cams 61 and 62 are disposed upon opposite sides of the guide shaft 26, and the cam 61 is arranged in the path of travel of a spring pressed pin 64, carried by the feed arm 41, while the cam 62 is arranged in the path of travel of a spring pressed pin 65, carried by the feed arm 41. Thepins 64 and 65 are disposed, upon opposite sides of the tubular extension 39, as shown.

The carriage 28 is provided with a lateral extension 70, to which is pivoted a depending trip 71, having a knee joint therewith. This trip islfree to swing to the right, but is rigid with respect to swinging movement to the left, Figure 4.'

The numeral 72 designates the transmitter of a telephone of the. usual construction, and .a tube 73 is secured upon this transmitter and leads to the diaphragm casing 32.

. In Figure 6, the numeral 74 designates the hook of the telephone, which closes the talking circuit at the points 75, when the reciver is raised. The receiver may remain upon the hook, and wires 76 and 77 are connected across the points 75, and lead to stationary contacts 78 and 79, carried by the, arm 31, and insulated therefrom. It will be seen that the talking circuit will be closed, as if the receiver were raised, when.

the contacts 78 and 79 are electrically connected. These contacts are electrically connected by means of a swinging contact 80, movable into.and out of engagement therewith, and this swinging contact is rigidly mounted upon the rock shaft 36, pivoted in places upon the cylinder 13 a record containing the desired message, and the eleravages ments of the machine are in the position, as shown in Figure 1. The carriage 28 has been shifted to the left, to approach the end of the reverse travel, but the head 43 still engages the reverse screw 19. The brake element 60 now holds the brake disk 12 against rotation. When the ringing circuit is closed, magnet 50 is energized, and the armature 51 is oscillated, and the ratchet wheel 54 turned. This movement of the ratchet wheel withdraws the brake element from the brake disk 12, and themotor is set in action. The carriage 28 now completes its movement to the left, the pin 64 riding up the shifting cam 61, and this shifts the feed bar 41 upon its pivot, causing head 43 to disengage reverse screw 19, and head 42 to engage feed screw 18. When this occurs, link 38 is drawn rearwardly and the bell-crank lever 35 is swung downwardly,

ing circuit isclosed. The head 42-engaging the feed screw 18, causes the carriage 28 to travel to the right, in its feeding movement, until the pin 65 rides upon the shifting cam 62, at which time the feeding movement is stopped. The feed bar 41 is again shifted so that the head 42 disengages the screw 18 and the head 43 engages the screw 19. The reverse movement of the carriage will now occur, and the trip 71 will engage the cam 56, and turn the same in the direction of its arrow. This cam turns-the ratchet wheel 54, and by the time the carriage approaches the end of its reverse movement, the brake 'element 60 will engage the brake disk 12,

sorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:
