The cam I (led with inwardly ex efiectively close tending ribs move back by gravity Fig. 2, and the operation is repeated as often as desired.

38 adjacent the sides of the opening in the casing and adapted to align the cam member in said opening thereby. Should the plunger with its sound chamber and valve tend to rotate in the casing and throw the arm 30 out of alignment with the cams 35 and 36, the projection 37 on the arm 30 may engage the ribs 38 and thus substantially prevent any such rotary movement of the plunger. The sound chamber is cut away or recessed at 39 in order to provide ample space to accommodate the valve arm 30. One of the cars 26 has an integral bent over portion 40 which acts as a stop to limit the opening movement of the valve 28. That is, the stop 40 carried on the sound chamber and plunger prevents the valve opening too wide and confines the movement of the arm 30 within suitable limits. The open end of the casing is shown covered with a perforated cap 41, through the perforations of which the sound is emitted.

In operation, with the parts as shown in Fig. 2, the plunger comprising the weighty member 8 and parts carried thereby will. slide down and descend in the casing by gravity. This causes the bellows 11 to gradually collapse and force the air therefrom through the reed pipe into the sound chamber. If the valve 28 is closed the escape of air will be so slow that the reed will not speak. When however, the plunger descends far enough for the cam 35 to engage the arm 30 and open the valve the reed will speak and utter a sound like ma for example, the termination or interruption of which sound is effected when the plunger descends to a point where the projection 37 slides off the cam 35 and the valve 28 drops under its own weight by gravity and closes the sound opening 24. When the plunger descends a slight distance 36 will engage the projection 37 on the arm 30 and again open the valve causing a sec ond but longer sound, like ma for example, to be heard. That is, the air in the bellows is compressed by weight of the fall ing. plunger the air is forced from the bellows through the reed pipe, and at those suc- 'cesslve times when the valve 28 is open the sound waves therereed will speak and the from will issue into the whence they pass through the sound opening 28 and out of the device through the apertures in the cover 41. The device is then turned upside down and the p'lungerwill to the position shown sound ch amber 23,

The device is compactly arranged so that it is conveniently inserted in the body of a doll and is operated by reversing the position of the doll.

Referring to Fig. 6 I there illustrate a modified method of'attaching the upper end of the bellows member 11 to the weighty 'pivotally mounted on the further the cam engage said arm to open the valve as iron head 8. In this form the depending circular flange on the member 8 is rabbeted or cut away at 42 forming a smaller circular flange of less diameter at 43. The flange 43 is provided with a peripheral groove and the upper end of the tubular bellows 11. is slipped over the flange 43 and firmly bound in the groove 44 by an encircling wire 45.

While I have thus described my improvements in great detail and with respect to preferred forms, I do not desire to be limited to such details and forms since many changes may be made and the improvements embodied in Widely different forms without departing from the spirit and scope thereof in their broader aspects. Hence I desire to cover all modifications and forms coming within the language or scope of any one or more of the appended claims.
