JULIUS HARRIS, F LIVERPOOL, ENGLAND, ASSIGNOR EMERY,

SOUND RECORDING AND REPRODUCI NG MACHINE.

To altwhom it may concern;

Be it known that I, JULIUS HARRIS, a sub;

'ject of the Kingof England, residing at more easily worked and at thesame time the mechanism is simple,'inexpensi ve, and eife'c tive, and capable of giving uniform and reliable results records, and in playing them.

, This invention will be described with the aid of theaccompanying drawings, which I illus'tr'atean auto-muslcal instrument of the character herein'referred .to, and in which "the improvements hereunderare comprised.

In these drawings, Figure 1 is a plan of one part, and Fig. 1 a plan of the other part of the improved mechanism, and Fig. 2 is an elevation partly in section of the improved mechanism. Figs. 3,4, and 5 are details hereinafter described, and Fig. 6 shows a part of the hand actuating means,

1, generally designates a rocking frame; 2 is a spindle on which the record table 3 is mounted; 4 is a pivoted spindle on which the frame 1 is mounted and about which it rocks; and 5 is the usual springmotor which is wound up by the movementof the frame.

The frame 1 has connected with it a lever 6., which is hereinafter nected with the spring motor 5 by a chain 7, one end, of which is connected up with the frame itself, and the other with the case 8of thespring motor 5'; while one end of the spring is'connected to the case, and the other with an arbor 9, which has fixed on it a toothed pawl wheel 10, which isheld against rotation in one direction by the pawls 11.

The frame 1 carries gearing by which motion is imparted to thercords disk and the or effects, both in the taking of actuated hand in the manner described; and the frame is con I Specification of Letters Patent. Application filed September 2, 1909., Serial No.

mechanism connected with the same through a fixed curved rack 13, which is attached to the carrier bed 14 of the machine, and held stationary thereon. This rack serves to operate the gearing carried by the frame 1, through a part of the said gearing engaging with such rack and being caused to travel over it by the'spring motor 5 which is connected with the frame 1 by the chain 7.

The gearing carried by the frame com-. prises a tooth wheel 15 which engages with the curved rack 13, and as the frame is moved by the spring motor 5' through the chain 7, the tooth wheel 15 is rotated by the teeth of the curved rack 13, and the spindle 16 of the tooth wheel also rotated, and such rotation of'the spindle 16 bevel wheel 20 through ratchet wheel 19 fixed to the spindle 16 and a spring pressed pawl 18 attached to the wheel 20, and which engages with the teeth of the-said ratchet wheel 1.).

The ratchet wheel pawl 18 are provided for the purpose of enabling thespring motor 5 being wound without operating the gearing, that is, when the framel is rocked on its spindle 4 away from the spring motor 5 the gearing carried by the frame is freed that is. the spindle 16 and ratchet wheel 19, rotate freely owing to the pawl 18 slipping over the teeth of-the ratchet wheel. p The rotation of the bevel wheel 20 transmits motion to the bevel pinion 21, andspindle 22, and the spindle 22 rotates the spiral tooth 'wheel 23, and a worm 24 on the record disk table spindle 2; thus motion is imparted to the said toothed wheels and spiral and worin gearing, by causing the tooth wheel 15 to move over and in engagement with the stationary rack 13 by the spring motor 5,

the medium of a and the record is rotated at the required speed, which is regulated as next described. The speed of rotation of the disk and its is transmitted to the 19 and spring pressed spindle 2 is regulated by the governor device 12 more particularly shown in Fig. 3.

This device is of the well known characterand is driven through the tooth wheel 25 mounted on the record table spindle 2, and a tooth pinion 26 gearing therewith and mounted on the spindle of the governor 'de' lower end which acts directly upon a pin 32 attached to the outer end of the lever 29. The end 28 of the lever 29 is normally pulled away from the disk'27 by the spring 33, attached at one end to the lever 30, and

at the other end to a part of the casing, and when the end 28 is-to be moved toward the disk, the nut 31 is screwed farther on to the screw threaded end of the spindle 4, and

rocks the lever 29 about its ivot 30 in such.

a manner as to move the en 28 of the lever toward the disk 27. The end 28 serves as a braking device for the disk 27, that is, when -the disk 27 is pulled downwardly by the weighted spring armsof the governor, the disk bears against the end 28, and the speed of rotation is checked or reduced thereby.

The end of the lever 29, may have an antifriction roller or ball upon it, which works in connection with 'the under side of the disk 27.

The sound box is mounted on gimbals as shown in Figs. 4 and 5, to give lateral play or movement and the proper adJustment and the needle will be pressed onto the record disk 10 by gravity, or by a. slight spring.

The gimbals consist of an inner ring 38, to which the sound box tube 37 is connected by pins 39; and the ring 38 has pins 40 on it, which are mounted in the outer ring 41 directly connected with the trumpet tube 42, which will be fixed or stationary, and is without a sound arm. .By this arrangement, it will be noted that the sound box 35 will have lateral play as wellas vertical play, and the needle is free to follow the impressions of the disk readily and accurately.

With regard to the spring 5, this may be of a single type, or consist of two or more laminae or springs.

The whole apparatus and parts described are mounted upon a suitable box, table or base 45; and the actuating lever 6 is preferably operated by a hand crank lever 46 on the outside of the box, which is connected up with the lever 6 through a spindle 47,

a drum or wheel 48 upon it, and a chain 49 which wraps around the drum. By moving this lever 46, say about half a revolution, the frame 1 will be completely moved from its terminal position to the starting position, that is, it will be fully set, so that upon remeans for regulating lease; the eompleteaction of the mechanism and record table will follow.

The winding of the motor spring, and the setting of the instrument generall is effected by rocking or moving the me or part carrying the spindle on which. the record table is mounted, away" from the spring motor; and when this-frame is released, the spring which has been wound up returns or moves backthe frame, and drives through the said toothed and other gearing and the stationaryrack, the record spindle and record disk.

As the frameand gear are moved or actuated by .the spring motor the disk will be moved relatively to the style or needle of the sound box; and the record will traverse therefor under the style or needle.

What is claimed is 1. In a sound reproducing or recording machine, a power motor, a recorddisk table,

and a movable record table carrying part,

. having a flexible connection with the motor,

whereby the latter is wound up when said part is moved in one direction, and said part is moved in the opposite directlon by the motor when the latter is released;

2. In a sound reproducing" and recording machine; the combination of a spring motor; a fixed toothed rack, a rockable ,frame on which are mounted a table for carryin the record, a spindle connected with the tab e, a governor device, and gearing for transmitting motion to the spindle including a toothed wheel which engages withthe fixed rack, and a ratchet device; flexible means connecting the frame with the spring motor; and means for moving the frame away from the spring motor.

3. In a sound reproducing and recording machine; the combination of a spring motor; a fixed curved toothed rack; a rockable frame on which are mounted a record carrying table fitted with'a spindle, a governor device, and gearing connected with the said spindle and which includes a ratchet device and a toothed wheel which engages with the fixed curved rack; a chain connecting the ,frame to the spring motor; means for rocking the frame away from the motor; and

the braking action of the governor device.

4. A sound reproducing and recording machine, comprising a spring motor; a stationary curved rack; a rockable frame comprising a record carrying table-fitted with a spindle, a spring governor device,-having a braking disk, and gearin which includes a ratchetdevice and a booted wheel Which engages with the curved rack; 21. chain connecting the frame to the spring motor; a hand actuated means for rocking the frame away. from the spring motor; a spring ac- Copies of this patent-may be obtained for five cents each, by

tuated braking lever having means for regulating the position of the-lever relatively to the braking disk of the governor; a sound box; and means for supporting the sound box over the record table including gimbals which enable the sound box to move both vertically and horizontally, and comprise concentrically disposed rings fitted With horizontally and vertically disposed pins and bearings,

In testimony whereof I afiix my-signature presence of two Witnesses.
