LEONARD FOUTE, OF lPARAISO, CANAL ZONE.v

PHONOGRAPH-MOTOR-WINDING DEVICE.

To all fwaomjt 'may concern:

Be it known that I, LEONARD Foo'rn, a citizen of the United States, and a resident of Paraiso, Canal Zone, have invented a new and Improved Phonograph-h/lotor-/Vinding Device, of which the following is a full,

` clear, and exact description.

This invention relates to phonographs, and relates more particularly to means for winding the motor which drives the recordcarrying turn-table.

The invention has for its general objects to provide an improved means for winding the motor through the medium of the tone arm which carries the reprodueer, whereby the swinging of the tone arm back and forth while the reproducer is in raised position will wind the motor through suitable mechanism between the tone arm and the usual winding shaft of the motor, such mechanism including a ratchet device whereby the tone arm is free to move inwardly from the periphery to the center of the record during the playing of the music, and 'also including a friction .clutch which yields -when the .motor is fully wound and' before the tone arm is brought back to its extreme position.

For a more complete understanding of the invention, reference is to be had to the accompanying drawings, which illustrate one embodiment of the invention7 and where- 1n similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of a phonograph of the disk type with the improvements applied thereto; Fig. 2 is a horizontal sectional view taken through a plane to show the motor and the operating connections between the motor shaft and the tone arm; Fig. 3 is an enlarged sectional view showing e gearing and ratchetconncctions between the tone arm and the shaft intermediate such tone arm and motor shaft; Fig. 4 is an enlarged sectional view on the line H, Fig. 2, to show the yielding clutch device for the motor; and Fig. 5- is a sectional view on the line 5-5, Fig. 4.

eferring to the drawings, 1 phonograph cabinet case, rying turn-table, arm, and 5 the designates a 2 the record-car- 3 the reproducer, et the tone amplifying horn which is connected in the usual manner with the vertical or axle portion 6 of the tone arm, which axle portion is disposed in the neck 7 Vof the horn, as shown in Fig. 3. The usual spring motor 8 connected through the Specification of Letters Patent. Application filed October 26,1915. Serial No.

worin gearing 9 with the shaft 10 of the turn-table 2. The motor has a shaft l1 made in two sections a and o, and keyed to the section (i is a sleeve l2 forming an element of a clutch, the other element being a split spring sleeve 13 having an external key 14 engaged: in a keyway l5 in the cylindrical section 1G of the beveled gear 17 which is keyed to the shaft section b.' The shaft section o may have its end 18, Fig. 2, so shaped as to be engaged with an operating crank` which is inserted through an opening 19 in the side of the casing, whereby the motor can be wound by hand. .The clutch device .formed by the elements A12' and. 13 forms a yielding connection between the two sections of the shaft so that the motor springs cannot bewound too tight. The use of an operating crank for winding the motor is intended only in case of emergency, as the motor isintended to be Wound by the movement of the tone arm Any suitable-operating means may be employed between the tone 'arm and the gear 17 to rotate the latter for winding the motor, but in theA present instance a secondary shaft 20 extends from the tone arm to the motor and has on one end a beveled gear 21 which meshes with the beveled gear 17, and the opposite end of the shaft 20 has a beveled gear which meshes with a. beveled gear 23 in the form of a ring loosely mounted on an annular bearing flange or equivalent part 24: carried by the vertical portion (i of the tone arm, as shown in Fig. 3. This gear 23 has ratchet teeth with which coperatie pawls 26 'pivoted on the vertical portion (i of the tone arm. These ratchets permitfthe tonearm to move freely the tone arm while the record is playing. That is to say, the arm Ican move freely from the right to the left 'as the needle travels from the periphery ytoward the centen` of the record, but in moving the arm in the opposite direction ratchet teeth to positively connect the tone arm with the motor, whereby'the latter is wound. Thev tone arm can be swung back andy forth tl'irough its full range of movement for the purpose of fully winding the motor. The tone arm is preferably provided with a handle 2T, Fig. l, so that the tone arm can be swung back and forth, the reproducer being of course thrown up and back to its raised position so as to be out of the way of the record 'or
