Description
June 16, 1953 c. SCHILLER GRAVfiY-ACTUATED MOVABLE DOLL Filed Aug. 30; 1951 2 Sheets-Sheet 1 ZA JA.
INVENTOR. CHARLES SCH/MEI? A T TOR/VE' Y June 16, 1953 g. SCHIELER GRAVITY-AGTUATED MOVABLE DOLL 2 Sheets-Sheet 2 Filed Aug. 30 1951 IN V EN TOR. CHARZ f3 SCH/L L E? A TTORNEY present invention may be installed. Bar II and bracket I2 constitute the framework which supports the mechanism of the invention. Bar II extends substantially longitudinally of the doll and it may reach from a point adjacent the top of the dolls head, referring to the cranial cavity, to a point adjacent the base of the spine. A portion I3 of bar I is bent at right angles to the bar to serve as a stop member for the weight hereinafter mentioned and a rubber band I4 is mounted on said bent portion I3 to serve as a bumper with respect to said weight. A pin I5 is affixed to the lower end of bar I I and a rubber tube I6 is mounted on said pin for the same purpose, namely, to serve as a bumper for the weight.
A cable 23 is attached at one end to one side of weight 25 by means of a screw 24 or other suitable fastening means and said cable is attached at its opposite end to the opposite side of the weight by means of screw 25. The cable is looped around a pulley 26 at one end of bar II and it is looped around a second pulley 27 at the opposite end of said bar. These two pulleys are mounted for retary movement, pulley 25 on shaft 28, and pulley 2! on shaft 23. The ends of these two shafts are supported by or journaled into annular bosses molded into the shell which comprises the head and torso of the doll. This is also true of all of the other shafts hereinafter mentioned. The
cable is also looped several times around a drum 36. Drum 36 is mounted on a shaft 3| which is normal to the longitudinal axis of bar II. This shaft is supported for rotary movement by that portion of bar I I which lies above bent portion I3 and by bracket I2 above mentioned. The drum is freely rotatable on the shaft and it will be understood from the arrangement of parts thus far described that when the weight is moved in one direction along bar II, the cable to which it is attached will cause the drum to rotate in a given direction, and when the weight is moved in the opposite direction along bar II, the cable will cause the drum to rotate in the opposite direction.
Fixedly mounted on shaft 3| is a ratchet wheel 33 and pivotally mounted on drum 36 is a pawl 34. This pawl is situated for engagement with the ratchet wheel and it moves in a planetary path circumferentially of the ratchet wheel when the drum rotates in response to the longitudinal movement of the weight. When the drum rotates in one direction, the pawl will have no effect upon the position of the ratchet wheel but when the drum rotates in the opposite direction, the pawl will engage the teeth of the ratchet wheel and cause said ratchet wheel to rotate with the drum. Other clutches may substitute for the ratchet.
A train of speed increasing gears is connected to shaft 3| and illustrating this train of gears is gear wheel 36 fixed to shaft 3| and pinion 3I fixed to shaft 36. Shaft 38 is rotatably supported by bar I I and bracket I2. Also affixed to shaft 38 is a fan 38 which serves as the governor of the mechanism herein described and claimed. It will be understood from this arrangement of parts that when weight 2|] moves in the direction of d scharge of energy, shaft 3| is caused to rotate and to drive shaft 58 through gears 36 and 3I. Shaft 38 will turn at a higher rate of speed than shaft SI and the fan will rotate at a speed corresponding to the speed of shaft 33. The fan blades will beat the air and resistance to rotation of the fan and all of the rotating parts connected to the fan will thereby result, enabling the fan to serve as a governor.
Fixedly mounted on shaft 3| are cams 46, 4 42 and 43 respectively. These cams actuate the movable parts of the doll through suitable cam followers and linkages. A cam follower 44 engages cam 46. Cam follower 4 9, is mounted on a rocker 46 which is supported by a pivot or shaft 47. The pivot is either fixed or journaled in the very structure which comprises the dolls head. This is also true of all of the other pivots or shafts to which the cam followers hereinafter mentioned are connected.
A weight 48 on rocker 46, tends to hold cam follower 44 in engagement with cam 40. Rocker 46 is connected to a rod 56 and said rod is attached to tongue 52 of the doll which is pivotally mounted on pivot 5|. When shaft 3| is caused to rotate by the driving means above described, cam
'66 will rotate with it and act upon cam follower #14 to cause the rocker to rock. Since the rocker is linked to rod 56, said rod will therebybe caused to oscillate and with it the tongue.
Cain follower is mounted on a second rocker 55 and said rocker is supported by shaft 56. A weight 51 on rocker 55 tends to hold cam follower 55 in engagement with cam 42 and hence said rocker will be caused to rock on shaft 56 when said cam rotates with shaft 3 I. Rocker 55 is connected by means of a link 58 and What may be described as a crank or torque arm 59 to a shaft 60. :This shaft is mounted for angular movement about its own longitudinal axis and it will be noted that said shaft 60 supports the eyelids 6| and 62 of the doll. Hence the rocking motion of rocker 55 will cause shaft 66 and eyelids El and 62 to oscillate.
A cam follower rides on cam 4| and it will 'be seen that said cam follower is supported by a third rocker 6E5. This rocker is mounted on shaft 56 and a weight 68 on said rocker tends to maintain cam follower 65 in engagement with cam 4|. Rocker 66 i connected by means of link "69 to a pivotally mounted bar I6 and said bar is connected by means of link II to a parallel pivotally mounted bar I2. Pivots or shafts I3 and I4 respectively support bars I0 and I2 and they also support eyeballs I5 and I6 of the doll. Oscillatory movement of rocker '66 will produce a corresponding oscillatory movement of bars 70 and I2 and of eyeballs I5 and I6.
A fourth cam follower 86 engages cam 43 and it will be seen that said cam follower is carried by a rocker tl. This rocker is mounted on pivot 82 and a weight 83 on said rocker acts to hold cam follower in engagement with cam 43. Rocker BI is attached to a diaphragm 84 by means of a link 85. This diaphragm forms part of a sound producing mechanism 66 of conventional design. When rocker 8| rocks by reason of the engagement of cam follower 80 with cam 43, the diaphragm 64 will produce currents of air which will cause the reed in said sound producing mechanism to vibrate and sound will thereby be produced.
A lever or rocker 90 mounted on shaft 9| projects into the path of weight 20 and when the weight engages said lever it causes the lever to tilt on its said shaft. A link 92 connects lever 90 to a crank arm 93 which is connected to a shaft 94. Secured to shaft 94 are the arms of the doll, only one of which, left arm 95, is shown. When lever 90 tilts in response to the action of weight 20 thereon, shaft 94 will be caused to turn on its longitudinal axis and the dolls arms will pivot upwardly.
The foregoing is illustrative of the broad principles of the invention and it will be understood that variations and modifications may be incorporated therein within the wide scope and broad spirit of the invention.
