JOHN LUKASZEWSKI, OF CHICAGO, ILLINOIS.

'LUTOMA'IIC STARTER FOR PHONOGRAPHS.

Application filed February 24, ,1923. SeriaI No. 620,954.

To all whom it may concern: 1 Be it known that I, JOHN LUKASZEWSKI,

lowing is a specification.

This invention relates to certain new anduseful improvements in automatic starters for phonographs and includes a clock having an alarm mechanism associated with the brake lever or foot of the phonograph turn table for shifting the brake lever at the desired time to release the turn table and permit the playing of a record, the device being intended for use in lieu of the ordinary alarm of a clock mechanism.

With the above and other objects in view as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure l is a fragmentary front elevational view of a phonograph constructed in accordance with the present invention, the tone chamber of the phonogra h being provided with a hinged door t at carries a clock mechanism, r

Figure 2 is a top plan view of the phonegraph with the cover removed showing the brake arm in engagement with the turn table, the latter supporting a disk record with the tone arm and sound box resting thereon,

Figure 3 is a vertical sectional view of the upper end of the phonograph showing the clock supported on the hinged door of the tone chamber, the brake rod for the turn table, and the connections between the brake rod and winding key of the alarm mechanism for the clock.

Figure 4 is a detail horizontal sectional view with the brake rod illustrated by dotted lines in its shifted released position,

Figure 5 is a fragmentary detail view showing the block to which the lower inner end of the brake rod is attached with the block illustrated in its shifted position by dotted lines,

Figure 6 is a detail sectional view taken on line VI-VI of Fig. 5 showing the head nograp a tone chamber 2 adjacent the upper end i of the winding key for the alarm mechanism seated in the block to which the brake arm is attached, and

Figure 7 is a detail sectional view taken on line VII-VII of Fig. 6.

Referring more in detail to the accompanying drawings, there is illustrated a phoincluding a box or casing 1 having thereof, the front end of the tone chamber being provided with a horizontally swinging hinged door 3. The tone chamber is provided with the usual upper wall 4 above which a turn table 5 is rotatably supported, and with which turn table, a tone arm 6 is associated as shown in Fig. 2.

The mechanism for effecting the automatic starting of the turn table 5 includes a clock casing 7 having the front face thereof set in a cutaway portion 8 in the door 3 of the tone chamber, the clock casing 7 being carried .by the bracket 9 that is attached to the rear face of the door 3 adjacent the upper end thereof as clearly shown in Figs. 1 and 3. The clock casing contains the usual mechanism, the main spring thereof being wound by the key 10, the alarm mechanisnrbeing set by the he 11 and wound by the key that includes t e shank 12 and head 13 of the form best illustrated in Figs. 6 and 7.

A standard or bracket 14 is $11 ported upon the floor board 15 of the tone chamber 2, and rotatably supports at the upper end thereof a laterally positioned vertical plate 16, to the outer face of which a block 17 is secured as shown in Fig. 6. The outer face of the block 17 is provided with a socket 18 of a configuration corresponding to the head 13 of the alarm mechanism key, the head of the key being received in said socket when the door 3 of the tone chamber is closed.

The brake rod 19 for the turn table 5 is of angle formation as shown most clearly i Fig. 3, the inner lower end of the brake rod 19 being anchored as at 20 to the upper edge of the block 17, while the upper end of sand brake rod extends through an opening 2i lli me hani m of. the 1o k;1. e e 'U Q; letter ,{heingbodi'l movable with the door-,3, and

the alarm eing set by the key '11 in the usual manner. When the-door is moved to a closed position, the head 13 ofthegalarm is gverticallg positioned as shown in Figs. 6 and 7 an is received in the socket 18 formedin the outer, face ofthe block 7, the brake shoe 22 being normallymaintained in frictional contact with the peripheral edge a of the turn table b the-spring25 as shown in Figs. 3 and 4. n lieu of the soundin of the usual alarm mechanism of ,thfercloc case, the key head 18 is rotated at the time.

that the-alarm is Set, causinga partial ro-. tation of the block 17! and plate 16, the block 1'1 being interlocked withflthe key head 13- ,efi'ecting a sliding movement of the brake rod 19 as shown by dottedllines in Fig. 4 todisplace the brakeshoe 22 from engagement with the peripheral edge of the turn table 5; 1 and permit rotation thereof with a record ;;mounted thereon: asshown-in Fig. 2, rotary movement of thetalarm key being limited by, the. chain 26 attached 'at one end of the shank ;12 of the alarm keyandhaving the:

other end thereof attached .to the: eye bolt 27 carried by the rear face Ofythe lock casing 7. The play of the record may be read- .ily discontiniied by moving the door 3 to an open position to disengage the alarm. key from the block 17 and permit the spring 25 to shiftthe brake shoe 22 into engagement with the turn table.

While them is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is .1. In a phonograph attachment of the type described, a turn table having a brake rod associated therewith, a bin ed door carried by the phonograph, a c ock case ineluding alarm mechanism carried by the door, a rotatable block connected to the indoor, a brake rod carried by the bottom Wall ofsaid sound box and extending through an oseningi'ormed in the top wall of said soun -box to position its outer end in proximity to the periphery of the turn table,

-and means connectin the inner end of the brake rodwith the c ock alarm mechanism ,zforgi'eleasing the turn table when the alarm I mechanism is released.

3, In a honograph attachment of the type descri ed, ,-a phonograph, including a sound box, a turn table rotatably positioned thereabove, and a hinged door forclosing one Wall thereof, a clock casing including alarm mechanism carried by said door, a winding key for the alarm mechanism, a brake rod supported by the bottom wall of said sound box and projecting through an opening formed in the top wall for frictionally engaging the periphery of the turn table, means for connecting the inner end of the brake rod with said winding key when thesaid door is in its closed position, and a section of chain connected to the winding key and clock casing for limiting rotary movement of said key.

4 In a phonograph attachment of the Etype described, a phonograph including a sound box, a turn table rotatably mounted thereabove, and a hinged door for forming one end wall thereof, a clock casing includingalarm mechanism carried by said door, a winding key for said alarm mechanism,

a standard carried by the bottom wall of said sound box, a block rotatably supported by the upper end of said standard adapted for engaging said winding key when the door is in its closed position, and a brake rod carried by said block extending through an opening formed in the top wall of said sound box for frictionally engaging the peripher al edge of said turn table.

In testimony whereof I afiix my signature.

JOHN LUKASZEl/VSKI.
