ih all who/wit may concern:

Be it known that l, HENRY C. MILLER, a citizen of the United States, residing at Waterford, in the county of Saratoga and State of New York, have invented certain new and usetul Improvements inControl ling Mechanism, of which the following is a specification-i.

This invention relatesto improvements in talking-machines, and more particularly the governor and stopping mechanism.

The prime object of the invention "is to provide a governor for a talking machine. may he set, previous to the starting or .machine, to uniformly produce the selecrendered. archer object of the invention is to 'inpie and efiectual automatic stoppin the motor when the end .rcci 1d groove'is reached.

The invention also relates to the specific ails of construction and arrangement of ts, all of which will be. hereinafter referred to and particularly pointed out in the claims.

in the drawings: Figure 1 is a vertical section of a portion of a motor for a talking machine, with my improvements applied thereto. Fig. 2 is a plan view of the same with the record support removed. Fig. 3 is a vertical section illustrating a slightly difierent form of my invention. Fig. 4- is a detail plan view of the same. Fig. 5 is a similar view, showing the automatic stopping trip in normal position. Fig. 6 is a detail section of a slight modification.

The numeral l, indicates a frame from which depend hangers 2, supporting a shaft 3, carrying a motor 1, comprising a spring barrel 5, a worm gear (hand means for making the operation of winding the motor noiseless, the same being indicated at 7. Depending from'the frame 1, is a hanger 8, formed at its lower end with an opening 9, pin 10, the upper end of the latter being of conic-ail formation. The pin 10, is rigidly held in position by a set screw 11. Supported on the conical end of the pin 10,- is a vertically disposed shaft 12, extending above the casing, and provided at its upper end with atransverse slot- 13, below which are threads 14;

A sleeve 15, is mounted on the shaft 12, and is threaded at its'upper'en'd at 16; to en gage the thread 14, on

the shaft, and it. is

ialso provided with a worm 17, with which the worm gear 6, meshes. Mounted near the upper end of the sleeve is a plate 18, having an enlargedportion 19, to iorni' a counterbalance, and a reduced portion to receive a centrifugal weight 19, pivoted at 20. The plate l8-operates in an annular flange 21, extending upwardly from the frame 1, the interior surface serving as a track against which a friction strip 22, on the weight 19, contacts to retard the speed of the motor. Above the plate 18', and mounted on the sleeve 15, is a record support 22, formed with a cut out portion or way 23. Extending from the outside toward the center of the record support and across the cut out portion 23, is a pin 2-i, held in place by a collar 25. The pin is threaded to receive a threaded nut 26, designed to operate in the cutaway portion 23, and provided with a depending stud, to which is secured one end of a spring 27, connected at its other end to a pin or stud 28, projecting from the weight 19. The end of the pin 2%, extends beyond the periphery of the record support 22, where it is knurled to provide a finger grip for adjusting the tension of the spring to regulate the centrifugal movement of the weight 19. This part of the invention relates to the governing mechanism, and is constructed and arranged so as to make itncccssary to set the governor preceding the starting of the reproduction of a selection, and to thereby avoid irregularities in the piece being reproduced, so common with talking machines now in use. To increase the speed of the motor, the pin 24, is turned so as to move the nut 26, outwardly, which movement increases the tension of the spring 27, which obviously requires greater speed of the plate 18, to throw the weight out- -wardly in contact with thelfiange 21. To slow up the speed the pin 24, is turned in the opposite toward the center, which relieves tension on the spring 27, and thereby allows the weight 19f, to be thrown outwardly more readily.

A boss or braking'surface 40, '(Fig. 1) depends from the frame "l, which cooperates suitable Wearing. surface such as leather or the like being interposed between said two surfaces. This detail of construction isv the direction to feed the nut- 26,

with adisk 41, carried bythe sleeve 15, a-

means I employ for stopping the motor at a 118 determined point, which, is automatic; controlled hy a tripping device actuated hy the stylus.

A cap d2, having a centrally disposed the upper end of the vertical shaft 12, the cross bill engaging the slot 13. An arr-n tends outwardly from the cap and has pivoted to-it a lever -it%, having a stop 45, ed ved to contact with the arm on the can cause the two elements to move simult-L' ously at the proper time,

The cap 42, and lever l are turned in direction of the arrow A, Fig. l, to dotted line positions through the cross and slot connection which also turns .shaft 12 and through the screw threads .l and 16 feeds the sleeve 15, and the dislr all, downwardly away from. the boss 48-; 'T'l lever 44, is turned on its pivot until its end crosses the last end of the groove of t record 47. As the record is revolved it is the stylus 48, toward the shaft 12, and WE? the last groove is reached it contacts v the free end of the lever 44, and causes Y turn on its pivot until the stop 45, with the arms projecting from the cap shown in full lines in Fig. 4:. llHllllG this position of the parts is assumed th movement of the shaft 12, is retarded, hu"

being elevated by reason of the threads engaging the threads 14, until the disk c. contacts with the boss 40, which stops motor at the time the end of the record groove is reached.

The lever i l, can be set to accommodate records of any varying lengths, which make it possible to automatically stop the machine at the end of any size record.

In Fig. 3, l have shown a slightly dill-3rent form of my invention which only differs from that shown in Fig. 1, in minor de l of construction,however, the basis of 1:; operation is substantially the sazne. in this figure the shaft 50, does not more ve 'tically, but is formed with an internally threaded opening at its upper end, indicated 5i, and a threaded pin 52, is fitted in said open-- ing. The pin 52, is provided at its upper end with a slot 53, and a cap i2, suclras previously described cooperates with it. An opening 54, is formed in the counterwei ht 19, and the shaft 50, through which passes a sliding dog 55, the inner end oi which is of conical formation and is in the path o'lf movement of the conical end of the pin While its outer end is normally in contact with the inner edge of the Weight 19. this construction when the cap 492, is re volved it feeds the threaded pin 52, down-- wardly, causing its beveled end to force the (log 5 outwardly in contact with the weight, until the latter impinges the inner wall of the annular flange ill, thereby stopopening with a cross bar 43, is fitted over r or use ventiozs in ovei 101:, the operator lino d necessary to re re nlayin a selroove The record sueport 22, is opening 8, directly o W31 a co'onter-hnlence it and leads duct- 80,tot,lie sleeve 15, and e 1135, or duct oil dropped cavity to 2 sleeve worm and he lower out sleeve is n t :1 with passage down the outs the cup and ends of the pi permitting of l i at l claim 1. ln combination, e s having stationary ennui tor inciurlu he s:
