vice for the purpose of predetermining the velocity or rate, of speed at which said part or parts shall revolve.

It further consists of other novel details of construction, all as will be hereinafter fully set fort v Figure 1 represents a side elevation of a portion of a phonograph or like device, showing my time indicator in position. Fig. 2 represents a plan view of the adjusting screw, a portion of the head being broken away. Fig. 3 represents a side elevation of a portion of thedevice shown in Fig. 1, with a different form of screw employed. Fig. 4 represents a plan view of some of the parts shovm in Fig. 3. Fig. 5 represents a partial side elevation and partial sectional View, show ing a form of screw that may be employed. Fig. 6 represents a plan view thereof, showing a portion of the head of the said screw broken away. Fig. 7 represents a front elevation, showing the manner of mounting the scale.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings. ings, I have shown adevice for indicating the speed at which the revoluble parts of a phonograph or a like device are to rotate in order to give the desired speed to the reproducing parts.

It will be evident that certain changes may be made in the construction shown which will come within the scope of my invention and I do not, therefore, desire to be limited in every instance to the exact construction shown.

1 designates a bed plate of the machine, to which is suitably attached, the hangers or bearings 2 carrying the governor 3.

In suitable connection with the governor 3 is a lever 4, which is pivotally mounted at a suitable stationary point and has connected therewith, a spring 5 'tending to move the In the drawsameupwards, it being understood that the proper movement of'the lever 4 acts upon the governor 3 to cause the same to rotate in a slower and faster manner as desired.

In threaded engagement with a suitable portion of the device is aset screw 6, which bears upon the end of the lever 4 for adjusting the-position of the same, said set.

screw having a disk or head 8, and a thumb piece 7 thereon, it being understood that as the set screw 6 is rotated it will move up- I wards or downwards in its support and will cause the free end of the lever to be moved in a corresponding direction and thus control the governor. j

-9 designatesa plate or scale which is provided with a slot 10 and has the graduations 11 thereon suitably numbered or provided with'indicators in order that readings may be made therefrom. I

11 designates ears suitably connected in the present instance with the bed plate. 1 adjacent the set screw 6, it being noted that the scale or plate 9 is adapted to be carried on said ears and that a'set screw 12 passing through said ears and the slot 10 in the plate is adapted to lock the same in proper position, it being understood that by reason of this construction, the scale or late can be raised or lowered to a desired a justed position. By reason of the position of the scale, the disk 8 will register in its movement with the various graduations of the scale, so that the position of said setscrew and of the lever 4 can be positively determined and {llUSd .the speed 'of the phonographs reguate I Upon the upper face of the disk 8, I may provide graduations or a scale 13, so that the position of the set screw ca be made-in an accurate manner and to any egree of fineness. It will be understood that the scale or plate -9 can be adjusted depending upon the phonograph or the like to which it is applied,

after which the readings can be made as a collar 15 from which projects the yoke 16,

the arms of said yoke being adapted to seat or receive the scale'or plate 9, so that the' ice may be accurately taken.

lever, a set screw co-acting'with said lever.

to adjust the same, a disk on said set screw, graduations on said disk and a scale adjacent said screw having graduations thereon from -,which readings may be taken depending u on the osition of the disk.

2. In a evice o the character described, a

lever, a set screw directly engaging and coacting with-said lever, a graduated member carried by said set screw, a scale independent of and coacting with said graduated member "and havinggraduations thereon with which said member registers whereby the speed of the device can be determined and means for adjusting said scale parallel with said set screw.

- 3. In a device of tlie character described, a

lever, a set screw having its end resting directly upon and co-acting with said lever,

a disk on said set screw, a head on said set screw above said disk and of smaller diameter, and a scale adjustably mounted adjacent said disk from which readings can be taken directly by said disk.

4. In a device of the char cterdescribed, a lever, a set screw co-acting with said lever, a

plate having graduations thereon, ears suit-- ably supported, and means for adjustably connecting said scale with said ears whereby said scale can be adjusted with respect to the mechanism.

5. In a device of the character described, a i

lever, a set scre'wcoacting with said lever, a yoke carried by said set screw and a scale adjustably mounted adjacent said set screw and seated in said yoke.

6. In a device of the character described, a

' lever, a bodily movable set screw independent of and bearing on said lever to adjust the position thereof, a thumb piece or head on said set screw, an indicating member carried by said set screw and a' scale mounted in proximity to and parallel with said set screw and at right angles to said indicating member.
