     BRIEF DESCRIPTION OF THE DRAWINGS 
     The features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The invention, together with further objects and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawings, in the several figures of which like reference numerals identify like elements and in which: 
     FIG. 1 sets forth a front perspective view of a doll constructed in accordance with the present invention; 
     FIG. 2 sets forth a partial front perspective view of the present invention doll having a pacifier received therein; and 
     FIG. 3 sets forth a partial section view of the operative mechanism within the present invention doll. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 sets forth a front perspective view of a doll constructed in accordance with the present invention and generally referenced by numeral 10. Doll 10 includes a body 11 preferably formed of a soft plush material and having a torso 12, a pair of arms 13 and 14 supporting hands 21 and 22. Torso 12 further supports legs 15 and 16. A head 25 is supported upon a neck support 41 and includes a mouth 30 having an aperture 31 formed therein. A socket switch 42 is supported within head 25 by conventional means (not shown). Socket 42 is operatively coupled to a connecting wire set 43. 
     In further accordance with the present invention, a movement and sound unit 40 is supported within torso 12 and is operatively coupled to socket 42 by connecting wires 43. A pressure sensitive start switch 23 is supported within hand 22 and coupled to unit 40 by a plurality of connecting wires 24. A pacifier 17 is supported by a tether 18 secured to arm 13 of doll 10. 
     In operation and by means set forth below in greater detail, the user presses start switch 23 causing unit 40 to begin producing a hiccupping sound and to begin raising and lowering neck support 41 to move head 25 in the direction indicated by arrow 26. The hiccupping will continue as the user endeavors to undertake activities which will cause doll 10 to cease its hiccupping. Thus, for example, the insertion of pacifier 17 through aperture 31 of mouth opens the switch within socket 42 terminating the hiccupping action and sound. Alternatively, an inertia switch 50 (seen in FIG. 3) responds to certain other movements such as patting the doll&#39;s back or lulling the doll to sleep in a cradle-like position. 
     FIG. 2 sets forth a partial perspective front view of doll 10 being held in a cradled position. Doll 10 includes a head 25, a body 11 having a torso 12 and an arm 13 supporting a hand 21. Head 25 defines a mouth portion 30 which receives a pacifier 17. In the configuration shown in FIG. 2, the user has quieted doll 10 and terminated the hiccupping sound and action by the insertion of pacifier 17 into mouth aperture 31 (seen in FIG. 1). 
     FIG. 3 sets forth a partially sectioned front view of the action feature mechanism of the present invention doll. A movement and sound unit 40 defines an internal channel 91 within which a slide housing 90 is supported. A pair of springs 93 and 94 couple slide housing 90 to a fixed bar 96 to provide a spring force urging slide housing 90 toward bar 96 forming the contracted position of slide housing 90 shown in solid-line representation. 
     Unit 40 further includes a sound circuit 60 having a printed circuit board 62 supporting a plurality of electronic components 63 together with an integrated circuit sound device 61. 
     Sound circuit 60 is fabricated in accordance with conventional fabrication techniques and utilizes an internal memory having stored audio data and a microprocessor having a stored instruction set to provide sound signal output. As is well understood by those skilled in the art, a variety of standard speech or sound circuits may be utilized in place of sound circuit 60. The essential characteristics of sound circuit 60 is the provision of appropriate signals to speaker 66 for audiblizing a predetermined speech message or sound combination each time switch 23 is activated. For example, a combination of a microprocessor, read only memory, speech synthesizer and audio output amplifier suitable for the functioning of circuit 60 is formed as a single integrated circuit chip device manufactured by Texas Instruments, Inc. under the device name TMS50C44. However, it will be understood that a variety of standard integrated circuit devices may be used for circuit 60. 
     A movement mechanism within unit 40 includes a motor 70 operatively coupled to one or more batteries (not shown). Motor 70 includes an output shaft 71 supporting a pulley 72. A pulley 74 is rotatably supported within unit 40 and includes a gear 75 joined thereto. A flexible belt 73 couples pulley 72 to pulley 74. Gear 75 engages a gear 76 having a smaller gear 77 which in turn engages a gear 78. It will be noted that gear 78 is supported upon a common shaft with gear 75 but is freely movable with respect to gear 75. Gear 78 further includes a smaller diameter gear 79. 
     A cam 81 is rotatably supported upon a shaft 83. Cam 81 is rotated by the engagement of gear 79 with gear 80 upon shaft 83 in the direction indicated by arrow 82. 
     A cam follower 95 is secured to slide housing 90 at its upper end and extends downwardly against cam 81. Thus, as cam 81 rotates, the high portions or lobes of cam 81 force follower 95 upwardly against the force of springs 93 and 94 raising the head portion of doll 10 in the above-described hiccupping motion shown in FIG. 1. Each time the low portion of cam 81 contacts follower 95, the force of springs 93 and 94 returns cam follower 95 and slide housing 90 to the lowered position. 
     Unit 40 further includes an inertia switch 50 operatively coupled to sound circuit 60 together with a start switch 23 coupled to circuit 60 by connecting wires 24. A pair of connecting wires 51 couple inertia switch 50 to circuit 60. 
     In operation, unit 40 initially rests in the compacted position shown in solid-line representation. When the user actuates start switch 23, motor 70 is energized rotating pulleys 71 and 74. The rotation of pulley 74 communicates rotating power to gear 79 through gears 76, 77 and 78. Gear 79 engages cam gear 80 causing cam 81 to rotate in the direction by arrow 82. This rotation drives cam follower 95 and slide housing 90 to the raised position shown in dashed-line after which cam 81 continues rotation allowing springs 93 and 94 to restore slide housing 90 to its lowered position. As cam 81 rotates rapidly, the up and down motion of head 25 resulting mimics the action of a child hiccupping. 
     The activation of unit 40 achieved by pressing start switch 23 also causes sound circuit 60 to output a hiccup-like sound. This process continues on a repeated basis until the user manages to stop it. The user may stop the hiccupping action by either manipulating the doll and petting it or the like which activates inertia switch 50 to deactivate motor 70 through circuit 60 or, alternatively, the user may insert pacifier 17 (seen in FIG. 1) into mouth aperture 31 and switch 42 to again disable motor 70. 
     What has been shown is a doll having a hiccupping feature in which a realistic head motion is imparted to the doll which closely mimics the hiccupping sound produced by the sound circuit therein. 
     While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
