OSCAR ARNOLD, OF NEUSTADT, NEAR COBUIiG, GERMANY.

PHONOGRAPH.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed July 28, 1906. Serial No. 328,230.

To all whom it may concern:

Be it known that I, OSCAR ARNOLD, a sub- 'ect of the Emperor of Germany, residing at eustadt, near Cobur Germany, have invented certain new and useful Im rovements in Phonographs, of which the fo owing is a full, clear, and exact description.

This invention relates to improvements in honographs and has to do more particuarly with improved devices for 0 crating the recorder or reproducer support a roast of the record and also to improvements in braking mechanism adapted for use in connection with such machines. .One of the objects of the invention is to providemeans for moving the recorder sup port abreast of the record and to so construct said means as to obtain automatic return of the record or reproducer sup ort to an initial position after the record has been reproduced or recorded, as the case may be, for the purposes of reproducing or recording a new record. I

A .further' object is to provide improved braking mechanism for automatically arresting and permanently braking the recorder or reproducer support and the driving mechanism at a predetermined point in the operation thereof.

The invention will be more fully described .in connection with the accompanying drawing and will bemore particularly pointed out and ascertained in and by the appended claims.

In the drawing the figure is a view in elevation of a machine embodying the main features of my invention.

Like characters of reference designate similar arts throughout the drawing.

e invention will now be described in detail in connection with the specific form illustrated but it will be understood thatthe invention is not to be limited to such specific showing except for such limitations as the claims import.

As shown the mechanism is mounted upon a suitable base a rovided with a su port 1) adapted to form a caring for a recor holder spindle 0 upon which latter is mounted the record support or holder d. In the specific showing made the device of my invention is appslied to machines having 0 lindrical recbut'its application is not imited to this or class of machines. The .record holder (1 is driven by means which as shown consists of a train of gears connected with a source of power, said train comprising a gear f meshing with a ear f and communicatlngtherethrough by gears f 2 and f 3 with a source of power which is indicated at 10 and which may consist of-the usual clock spring. A main shaft or driving member f is provided and is adapted to be driven in one direction for operating parts hereinafter to be described and reversely operated for restorin said parts to an initial position. To this en said shaft may be provided with lugs or pins f 5 adapted to be engaged by a windin crank. A suitable governor a may be provided and as shown said governor is mounted upon a shaft n, having a hearing at one end 11 in a suitable stationary part and at its other end in a pendent support 2 secured to the base a.

A sheave m is provided on the record holder b and a pulley n onthe shaft n over which is trained a belt m which constitutes the specific means herein shown for o eratively connecting the governor with the record holder. Said shaft 11. carries a braking disk or member 1 adapted to be engaged by means for normally or permanently maintaining the device in a position of rest, which means as shown, consists of a spring brake o secured at one end to the support 2 and engaging at its free end the braking disk 1 An adjusting screw 0 having threaded engagement with the support 2 is ada ted for engagement with the s ring 0 to eit er hold the latter permanent y out of engagement with the disk 1 or permit it to permanently engage the same.

A support is is provided and adapted for attachment with either a recorder'or reproducer and is provided with means 42 for the reception of a horn or a speaking trumpet.

Said su pport 7c is adapt to be operated abreast of the record to carry the recorder or reproducer across the face of thesame and is operatively related with the driving means in such a manner that when the latter is operating to eiiect a reproduction or recording of a record the support is moved from an initial 'osition in one direction until the record has been reproduced or recorded and when the driving means is reversely operated the support is automatically restored to aninitial position. I

c As shown the shaft f is provided with a holder driven from said train, a g

provided with a brake disk and driv', n rom Y "e nor said record holder, an automatic braking de-" vice comprising a spring mounted brake shoe adapted for engagement with said disk and a slidably mounted support, a spring brake-for said supcport, a nut carried bv' said wprm and provide with a pin adapted to engage said automatic brake sup ort, a transmitter support mounted on said nut, and means for throwing said automatic brakin device o'ut of engagement with said brake disk.

4. A talking machine comprising in combination, a spring barrel, a shaft therefor provided on one end with projections adapted to be engaged by a winding crank and having a worm formed on its op osite end, a ear train driven from said sha t, a record ho der driven from said train, a governor driven from said record holder and provided with a brake disk, a braking device comprising a brake shoe ada ted for engagement with said disk and aslida 'bly mounted support, a brake for said su port, a nut carried by said worm and rovi ed with afpin adapted to engage said rake support to throw said shoe into engagement with said disk, atransmitter support mounted on said nut, and means for throwing said braking device out'of engagement with said disk.

5, A talking machine comprising in combination, a spring barrel, a shaft therefor provided on one end with rojections ada ted to be engaged by a winding crank and aving a worm formed on its opposite end, a gear train driven from said shaft, a record holder driven from said train, a governor driven from said record holder andprovided with a brake disk, a braking device comprising a brake shoe adapted for engagement with saiddisk and a slidably mounted support, a brake for said support, a nut carried y said worm and provided with a pin adapted to engage said brake support to throw said shoe into engagement with said disk, and a transmitter support mounted on said nut. 6. A talking machine comprising in combination, a winding shaft provided on one end with a worm, means for drivin said shaft, a gear train driven from said s aft, a record holder driven from said train, a governor driven from saidrecord holder and provided with a brake disk, a braking device co- 0 crat ng with said disk, means for holding t e braking device in a non-operating position, a transmitter support actuated by said Worm and engaging said braking device to throw the same into an operating position, and means for throwing said braking device into a non-operatin position.

7.-A talking mac me comprisin in com-- bination, a main shaft provided wit a Worm, means for driving said shaft, a gear train driven from said shaft, arecord holder driving from said train, a governor driven from sald record holder provided with a brake disk, a brakin device cooperating with said disk, yielding y acting frictional means for holding said braking device in a non-operating osition, and a transmitter support 0 erate by said worm and engaging said bra ing device, to throw the same into an operating position.

8. A talking machine comprising incombination, a main shaft provided with a worm, means for driving said shaft, a record holder operatively connected with said shaft, a governor driven from said record holder and provided with abrake disk, a braking device cooperating with said disk, a transmitter support operated by said worm and engaging said braking device to throw the sameinto an operating position, manually operable means for disengaging said braking device frgmsaid disk, and frictionally ac'tingmeans fo rimaintaining said braking device in its disengaged position. h
