Specification of Letters Patent.

Application filed September 1, 1916. Serial No. 118,025.

To all whom it may concern:

Be it known that I, LEWIS Corinna citizen of the United States of America, and a resident of Chicago, county of Cook and State of Illinois, have invented certain new and useful Improvements in Phonographs, of which the following is a specification.

This invention relates to phonographs' suitably arranged for use in toys and other devices, such as cigar cutters, clocks, dolls, savings banks, etc.

The objects of the invention are to provide simplified and improved means for starting, stopping and governing the speed of devices of this class; to provide improved means for automatically disengaging the 7 tion.

Fig. 8 is a sectional detail taken on the line 8-8 of Fig. 2, and shows part of the starting and stopping spring lever.

This invention provides simplified and improved devices in the structure of small phonographs whereby the same may be pro.- duced at low cost, but still permit of a great number of operations thereof without any appreciable deterioration of'the mechanism.

Power is supplied to the device by means of a small clock mechanism incorporated therein and comprising gears 1 to 6 inclusive, connecting a spring motor 7 with a rotatable record'support 8. The record sup port 8 is fixed to a sleeve 9 surrounding a winding spindle 10 journaled therein. The

rotating. the gear and servesto drive the winding of the spring. The outer end of the spring 7 is secured to a tie rod 12 Fig. 3. For the purposeoflimit- 'ing the winding of spring '7, spindle 10 carries fast an arm 13 in position to engage a fixed stop pin 14, Fig. 6.

' The starting and stopping and the speed of the device are controlled through a governor 15. The latter comprises a spindle 16 to which are secured pinion 17 and arm 18.

The pinion 17 receives motion from the gear 5 with which it meshes, at such speed as to cause the small weights 19 of the'governor to becomeeifective in shifting a disk 20 slidable on spindle 16 into engagement with pad 21, against the. action of spring 22 surrounding the spindle. The weights 19 are supported in balanced relation by the pivoted links 23 connecting arm 18 with disk 20. Longi- .with more or less pressure, and

tudinaltlfiaist of spindle 16. is prevented by springs 24 hearing against the ends of the spindle and supported byathe frame plate 25 and bracket 26 on frame plate, 27.

The sound reproducing disk 28 is mounted in the sound box 29 supported on frame plate 27. The disk or diaphragm 28 has attached centrally thereto a wire 31 connecting itto a pivoted stylus arm 3 2,'the latter being provided with a jewel tip 33 for engagement with record surfaces. The stylus arm 32 is pivoted to an ear 34 of a swinging arm 35 which in turn is pivoted on a fixedpost 36. I

Arm 35 is made of spring steelor some other resilient material to afford the required pressure between the stylus and record and still permit the stylus arm to be rocked clear of the record without necessitating an extra pivot or universal joint. lateral extension 35.1 coacting with a restoring cam member 37 on an oscillating shaft 38. When shaft 38 is rocked, the swinging arm is restored to normal position, after being driven along the record surface by engagement therewith.
