graph, such as the usual recorder or "cutter I head, or the reproducer or pick-up, is securely locked in position when not in use, whereby the phonograph may be moved without danger of the needlg of the translating device damaging the recor Another object is to provide a mechanism of the class described wherein the control of the.

phonograph is effected without mechanical connections between the control devices and the phonograph motor, thereby permitting an ordinary phonograph motor and record table to be used, the control devices per se being mounted on the tone arm.

a A further object is to provide a device of the character described wherein the complete cycle of operations of the device is controlled from and by the movement of the sound record.

Other objects will be apparent from the following specification wherein, by way of illustration, is described a simple and' compact phonograph mechanism suitable for use as a telephone answering device. It will be apparent, however, that the inventon is not limited to such apparatus, but may be employed wherever suitable and where it is desired to operate the instrument cyclically,

relatively movable and, as will be more fully the grooving, as such arrangements are well understood; and

Figure 6 is a diagram or the circuit connections of the mechanism shown in Figures 1 to 4, inclusive, in combination with an ordinary telephone instrument.

In the co-pending application for patent, Serial Number 509,544, filed November 1, 1943, is described a phonograph-telephone combination wherein a phonograph supports a subscriber's telephone so as to answer the telephone in the subscriber's absence and deliver to the calling party any messageleft on the phonograph. The telephone instrument is removable from th'e phonograph cabinet on which it is supported. Such messages are seldom of more than thirty seconds duration.

' If the phonograph is physicallycombined with the telephone and the latter is of the portable variety, having a casing containing the ringer, switching mechanism et cetera, and supporting the usual handset, when the combined instrument is moved, the tone arm of the phonograph will be displaced from the record. This will destroy the sequence of operations or the phonograph, and the record thereon may be damaged. The present invention prevents this and permits the phonograph-telephone combination set to be used even it the telephone and phonograph are in the same portable casing or cabinet and physically connected together.

Referring to Figure 1, the numeral i 0 denotes a base plate carrying the support H to which is secured the rotatable tone arm I: by the usual means such as the pins l2 entering'a groove in the support.

. The arm is, by this means, free to swing laterally over the record and to be moved vertically toward and away from the record at any point The record and arm are, therefore,

explained herein, cooperate for a predetermined time when the device is in operaton.

The arm I3 carries a suitable translating device such as the usual reproducer H adapted, when the arm is raised and lowered, to respectively contact and vertically clear the record 15.

. The mounting and construction of these arms are well known and any suitable arrangement can be employed. I

' The record blank l5, as shown in Figure 5, may be about 4%" in diameter, and if so, the first grooving thereon may consist of a comparatively coarse lead. groove it which leads into the sound recording grooves I! which in this size record for a thirty second recording will be about V4 wide.-

The sound recording groove leads into a comparatively coarse end grooving II. The lead and end grooves l6 and I! may be omitted but are of advantage. In any event, the total lateral travel 01 the outer end of the tone arm l5, when in operation on any one recording, is but little more than 94;", and the travel at about the center 01 the arm where it is controlled is only about it".

The arm I! has formed therefrom two downwardly extending ears I9, 20 supporting the shaft 2| upon which is mounted the rollers 22, 23.

A stationary jaw 24 shaped as shown to extend over roller 22 is secured as shown at 21 to the armature 2! oi a relay or electro-magnet, the magnet coil 01' which is indicated at 28. A spring 29 causes the armature to assume'the position shown in Figure 3 and the Jaws 24, 2' then grip their associated rollers 22, 23 and hold the arm II in the up position with the needle of the translating device I4 out or contact with the record I 5. Thus, the arm is held firmly when the device is not in use and it can be moved about without displacing the arm or damaging the record.

Referring to Figure 6, a common batter telephone line circuit (or any communication circult) is shown at Ll L2 to which is connected any suitable communicating apparatus such as the telephone instrument shown within the dotted lines 30. This includes a ringer R having contacts 3| adapted to be closed when the ringer operates as described in U. S. Patent 2,332,359, dated October 19, 1943.

When the ringer operates and contacts 3| close. a circuit is established from current supply wire 32, through switch 42, conductor 33, contacts. ll, conductor 34, winding 28 of the relay. through normally closed switch contact 35 on the tone arm switch to current supply wire it. This causes the relay to close contacts 31 which short circuit contacts ll so that the relay is locked in circuit.

A circuit is also completed by contacts 31 through the phonograph motor a which now begins to operate to rotate the record It. At or about the same time contacts I! close, contacts 39 also close, connecting the translating device It across the telephone line. This device may be a transmitter button adapted to be acted upon to transmit the sound recording II on record ll.

When winding it attracts its armature 21, the, movable law 28 attached thereto drops toward the record, thereby releasing the rollers 22, 23 and arm l3 attached thereto so that the arm drops toward the record and the needle or the translatine device I enga es the lead groove It thereon and is guided thereby into the sound recording l1 and from there rims-into the end groove it. These grooves (orthe recording I! ifthe other grooves are not used) moved the arm I: from right-to lei't, Figure 4. At the end of this travel, the adjusting screw ll makes contact with the operating lever of the normally closed-switch II which opens its contacts. This opens the current upply circuit, as shown in Figure 6, and the circuit is broken through motor 88 and relay winding 28. The relay releases contacts :1 and 89, and the spring 29 moves the armature 21 to the position shown in Figures.

As armature 21 is movedbythe' springthe movable jaw 28, in rising with the armature, picks up the roller 23 and the arm II. The rollerrolls down the slope 4| on the jaw 2i and the arm ll moves back to the initial starting position above but out of contactwith the beginning of lead groove l6 and the device is ready for the next cycle of operations.

Several diflerent recordings spaced-apart can be made on record l5, and by shifting the plate It by means of clamp screws 43 in a manner obvious from the drawings, Figure 4, the arm l3 may be positioned to start in the lead groove It to repeat the recording at IT, or to start in' lead groove Itto repeat recording l1 and to repeat the selected recording as long as it is positioned to do so.

An ordinary acoustic pick-up phonograph may be used, with a spring wound motor and connected and operated as described in application Serial Number 518,346 dated January 15, 1944, the reproducer It being positioned to cause the reproduced sound to impinge upon the transmitter of the telephone.

In this arrangement the contacts 39 are unnecessary, the telephone hook switch H being mechanically raised by the operation of the phonograph when some is in operation, all as described in the co-pending application Serial Number 518,346 aforesaid.

The construction and arrangement of the contacts 31, 39 on the relay are not described in detaiias these can be or any desired construction, and one form is shown in Figures 1 to 4. Also, the contacts 15 may be any suitable form of switch adapted to be operated by the arm I3.

A recorder can be used at ll if a pre-grooved record is employed, and the device used for recording, the cyclic operation being same a scribed. j It will be observed that the cyclic operation of the device is brought about by the grooves on the record and the movement-thereof. These control the motion of arm I3 and the operaation oi the relay to restore the arm to starting position. Thus, all motor drivenmechanical devices and connections to motor 3! are eliminated, the motor merely driving the record II which may be of any type, a disc record being shown by way of illustration.

This invention enables a small phonograph to be mounted within the base of a portable telephone without materially increasing the heighth of the instrument. This is because of the small travel of the arm I! and the compact arrangement of the control relay mechanism therefor, said mechanism not only restoring the arm to starting position after each operation. but also controlling the necessary circuits to eil'ect the cyralila1 of operations when the device is answering a I It will be seen that the telephone can be used in the usual manner. and by opening switch 42 the phonograph is rendered inoperative, yet arm I3 is firmly held 01! the record.
