' PHoNoeR' PH SPEED-INDEX.

Specification of Letters Patent.

Patented J an. 30, 1906.

Application June 29, 1904. Serial NO- 214,598.

T at whom it may concern Be it known that I, PETER WEBER, a citizen of the United States, residing at 571 Park sirable practical requirement, since, as is well known, it is highly important that a phonographic musical record should be reproduped at the same surfacespe'ed at which the original master record was secured, and with present devices the determination of the proper speed is a matter of careful adjustment and with most users a question of mere guesswork.

My invention provides a very simple index by means of which the phonograph maybe adjusted at the desired speed without the necessity of any experimentalmanipulation.

'In order that the invention may be better 'understood,attention is directed to the accompanying drawings, forming a part of this specification, and in which- Figure 11s a sectional view of a part of the mechanism of an ordinary phonograph, showin the top plate, motor-frame, governingever, governing-disk, and adjustingscrew, with my present improvements applied thereto; and Fig. 2, a'top view looking. down on the adjusting-screw.

In both of the views corresponding parts are represented by the same reference numerals.

The top plate I carries the motor-frame 2 in the usual way. The high-speed-shaft of the spring-motor (not shown) drives the gov ernordisk 3, with which cooperates a pad 4 on the governing-lever 5. As the (sipeed of the motor increases, the governor isk 3 is drawn into engagement with the pad 4 until the friction developed tends to retard any further acceleration in the-speed and maintains the speed constant at a point determined by the position of the governing-lever. Engaging the governing-lever is adjusting screw 6, workin inthemotor-frame 2 and havin a milled ead 7, by which it may be .turne Theparts so far described are of the usual construction.

Mounted on the adjusting-screw 6 is a collar 8, car an index 9, which cooperates with a scale 10 on the top plate, A stop 11 is engaged by the index 9 to prevent the adjusting-screw from'bein turned more than a complete rotation, so at when the index 9 corresponds with any figure on the scale 10 the s eed of the motor will correspond,

to that gure. The collar 8 is adjustably mounted on the shank of the adjusting-screw 6 and secured in a position by a set-screw 12, so that theparts can be read usted from time to time to accommodate any-slight'wear of the pad 4'or any lost motion in the operating parts. i

' Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

1 The combination with the governor-disk, governing lever and adjustingscrew of a sprin -opera ted phonograph, of an index carried y the adjusting-screw and cooperating with a stationary scale, and means for preventing the adjustin -screw from being turned more than a complete revolution, substantially as set forth. r 2. In a phonograph or the like, and in combinatidn with the speed-adjusting screw, of a finger adjustably carried by the screw, and

a stop in the path of said finger.

This specification signed and witnessed this 28th day of June, 1904. I PETER WEBER.
