13 Claims.

This invention relates to a talking machine and concerns itself with a structure that is adapted to be placed in the body of a doll for producing a talking doll. More specifically the invention concerns itself with a machine of this character which can be set in operation from without the body of the doll and which automatically stops when a record has been exhausted and which will elevate and return the stylus to its initial position without requiring any manu al manipulation.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying a preferred form of this drawings which illustrate invention, and in which similar reference numerals refer to similar features in the different views:

Figure 1 looking in In describing the invention with reference to the drawings, it will be noted is supported by a pair of side plates 1 plate 2 which bridges the side plates.

be observed that a shaft ring to Figure 3, it will that the mechanism and a top In refer- 3 is journalled for rotation'between the side plates 1. A spur gear 4 is keyed upon the shaft 3 adjacent one side plate. This gear 4 is adapted to be rotated by a reciprocating rack bar 5 which is slidably mounted in a guide casing 6 which may be secured or welded to the adjacent side wall 1.

A bearing strip '7 is preferab top of the housing face for the top of ciprocating movement.

the rack ly positioned in the to form a good bearing surbar 5 during its re- The front end of the guide casing 6 terminates in a downwardly extending flange 8 which form s a shoulder that is adapted to be engaged by a shoulder 9 (Figure 5) on the rack bar 5. It will be noted that the rack bar 5 terminates at its front end in a handle member of reduced portions whereby the shoulder 9 is formed. The handle portion of the rack bar embodies a knob with a collar 5a which is adapted to abut the front end of the casing whereby the reciprocating movements of the rack bar 5 is limited to a predetermined movement.

Reverting to Figure 3 again it will be observed that a hub member 10 is keyed upon the shaft 3. This hub member 10 has a ribbon spring 11 secured thereto and wound thereon with the free end thereof anchored to a rod 12 that connects the side walls 1. It might be mentioned that this ribbon spring serves as a spring motor for actuating the driving mechanism as will later more fully appear. The hub 10 of the spring motor terminates in a flanged ratchet wheel 13. Adjacent the ratchet wheel 13 there is a large spur gear 14 which is loosely journalled upon the shaft 3 and is provided with a pawl 15 that engages the ratchet wheel 13. A spring 16 normally urges the pawl 15 into engagement with the ratchet wheel 13. The large spur gear 14 which is driven from the spring motor through the instrumentality of the ratchet wheel 13 and pawl 15 is adapted for driving a small spur gear 17 keyed upon a shaft 18 which is journalled between one of the side walls 1 and an L-shaped bracket 19 which is secured to the same side wall.

A spur gear 20 is secured upon the shaft 18 and this gear 20 meshes with a pinion 21 secured upon a shaft 22 journalled between the side walls 1. The shaft 22 carries a gear 23 which in turn carries a small pinion 24 secured upon a governor shaft 25 upon which a suitable governor 26 is mounted.

Reverting again to Figure 3. it will be seen that a sleeve member 2'? is loosely journalled upon the shaft 3 adjacent the hub 10. This sleeve terminates in a pinion 28 which meshes with the spur gear 20 and is driven thereby relative to the shaft 3. The sleeve 2'? which may be termed a sleeve shaft carries a record drum or cylinder 29 upon which a suitable record 30 may be carried.

The manner of supporting the stylus that cooperates with the record will now be explained. It will be observed that a cylindrical rod 31 extends inwardly from one side wall 1. A U- shaped member 32 is journalled upon the rod 31 by means of a pair of bearing lugs 33 which extend in parallel relation from one leg of the U-shaped member. A hangar 3 1 which is provided with a pair of parallel arms terminating in pintle portions journalled in the arms of the U-shaped member 32 forms the stylus bar. The stylus bar 34 comprises a pair of forwardly extending arms 36 which approach each other at their outer ends and between the outer ends thereof, the holder 37 for the stylus pin 38 is pivotally mounted. In referring to Figure '7 which shows one of the arms 36 broken away, it will be noted that the holder 37'has a tail portion 37a which extends beyond the pivot 39 of the holder. This tail portion 37a extends between the two arms 35. A coil spring 40 connects the tail portion of the holder with an arm 41 extending outwardly from the U-shaped member 32. A vibration conducting wire or the like 42 also conmeets the tail of the holder 37 with a. diaphragm,

43 which is suitably mounted'in a head 34 supported upon the top plate 2 of the frame of the machine.

The mechanism for elevating the stylus bar and returning the same to 'mitial position as soon as a record has been played'will now be set forth.

With reference to Flgure'3 it Zwillbe observed that 25 acolla'r 45 is secured upon one end of the shaft 3 and this collar carries an arm 46 which termimates in a right angle portion 47'that extends over the peripheral face of the record drum. Re-

" ferring to Figure 4, it will be seen that the portion 47 is in the form of a channel that slopes inwardly. The aforementioned stylus bar 34has a depending lug 48 which is normally located in the path of movement of the arm portion When the spring motor iswoimdup by pushing the rack bar. 5 inwardly,'the shaft 3 will be rotated and will rotate the arm 46 into the position shown in Figure 7. When the rack bar 5 is released and the record cylinder is rotated through the instriunentality of the spring motor,

the shaft '3 will be rotated in a reverse direction until the arm 46 rotates to the position shown in Fig. 2, and this will occur when the stylus has traversed the'complete cylinder. At this point the inclined portion 47 of the arm will engage the lug 48 and elevate the stylus bar from the record cylinder, and as soon as this stylus bar is elevated, it will slide along the inclined face of the portion 47 to the opposite side of the a record cylinder, that is, to its initial starting posi tion. To prevent thestylus from dropping oif the outer edge of the record drum, astop lug 49 has been stamped from thecasing.

While it appears that the operation of the machine should be clearly understood from the foregoing description, a brief summary of the operation will be set forth. In its normal position, the motor is unwound and it is necessary to wind the spring 11 before it will operate. The spring motor is adapted to be wound up by pushing the rack bar 5 inwardly until the collar 5a strikes the casing, whereby theshaft 3 will be rotated for Winding up the spring 11, and the arm 46 will be rotated to its starting position as shown in Fig. 7. During this operation, the ratchet wheel 13 will ride idly over the pawl 15 without rotating the gear 14. However, as soon as the inward pressure upon the rack bar 5 is released the spring motor will operate the gear 14 through the instrumentality of the pawl l5 and ratchet 13. The gear 14 will rotate the shaft 18 which is geared to the governor shaft as previously set rotation.

stylus pin will of course gradually traverse the same, and the arm 46 will gradually rotate with the shaft 3 as it is rotated by spring 11 in a direction reverse to that required to Wind the same. Until it engages the lug 48 on the stylus bar and elevates the same and causes the same to slide over the sloping face on the angled portion 47 to its initial starting position. It will of course be understood that the U-shaped member 32 supports the stylus arm for rotatable and swinging movement in order that it may be actuated by the control arm 46 in the manner set forth. When the stylus has completely traversed the record cylinder the rack bar will of course have movedoutwardly until the shoulder 9 engages the shoulder 8 on the casing to prevent further It will therefore be obvious that the reverse rotation of the shaft 3 will return the rack bar 5 outwardly into position for again winding up the spring motor.
