Ambulatory doll

A motorized, self supporting ambulatory doll having pivoting foot or ankle, knee and hip joints with internal hidden parallelogram linkages driving the legs in a realistic articulation as the doll walks or jogs. In addition, the doll's torso, head and arms pivot in cooperation and synchronization with the movement of the legs to enhance the realism of the movement of the doll. Two speed operation of the doll provides for selective walking or jogging operation and electronic speech is coordinated with the selected speed.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates generally to ambulatory dolls and more particularly 
to mechanisms for articulating a motor driven doll for self supporting 
ambulatory movement in a realistic manner. 
2. Background Art 
Dolls with motor driven moveable legs for simulating walking are old in the 
art. Thus, for example, dolls or other characters with motor driven legs 
articulated for walking are shown in Paluck U.S. Pat. No. 1,684,287 issued 
Sep. 11, 1928; Ryan U.S. Pat. No. 3,243,916 issued Apr. 5, 1966; Ryan U.S. 
Pat. No. 3,267,607 issued Aug. 23, 1966; Ryan U.S. Pat. No. 3,267,608 
issued Aug. 23, 1966; Gardel et al. U.S. Pat. No. 3,421,258 issued Jan. 
14, 1969; Lindsay et al. U.S. Pat. No. 3,425,154 issued Feb. 4, 1969; Ryan 
U.S. Pat. No. 3,445,960 issued May 27, 1969; Robbins U.S. Pat. No. 
3,484,988 issued Dec. 23, 1969; Ceccon U.S. Pat. No. 3,604,147 issued Sep. 
14, 1971; Gardel et al. U.S. Pat. No. 3,609,909 issued Oct. 5, 1971; 
Terzian U.S. Pat. No. 4,878,874 issued Nov. 7, 1989 and copending Terzian 
et al. U.S. patent application Ser. No. 07/646,167 filed Jan. 25, 1991. 
In addition, there are prior art dolls with motor driven moveable legs 
articulated for other purposes, as for example, Douglas et al. U.S. Pat. 
No. 3,475,857 issued Nov. 4, 1969 for a doll supported in a sitting 
position on a moveable wheeled hobby horse transporter; Terzian et al. 
U.S. Pat. No. 4,467,555 issued Aug. 28, 1984 for a swimming doll and 
Terzian et al. U.S. Pat. No. 4,507,098 issued Mar. 26, 1985 for a roller 
skating doll. 
The prior art dolls or characters disclosed in each of Paluck U.S. Pat. No. 
1,684,287 and Terzian U.S. Pat. No. 4,878,874 require a wheeled supporting 
structure and the doll disclosed and claimed in copending Terzian et al. 
U.S. patent application Ser. No. 07/646,167 requires the user to support 
the doll by its hands and arms during the simulated walking. Considerable 
efforts have been expended to make a self-supporting ambulatory doll that 
moves in a realistic human manner and is stable during walking. Toward 
this purpose, the dolls disclosed in Ryan U.S. Pat. Nos. 3,267,608 and 
3,445,960 use an inner leg assembly in combination with an outer leg shell 
to provide a parallelogram action to keep each foot of the doll parallel 
to the surface on which the doll is walking. In addition, to also help 
achieve stable, realistic walking, the prior art dolls of Ryan U.S. Pat. 
Nos. 3,267,608 and 3,445,960 as well as of Ceccon U.S. Pat. No. 3,604,147 
provide a moveable member at the bottom of the foot. In the Ceccon patent, 
the lowermost surface contacting plate members, that is, the soles of the 
shoes, are spaced from the bottom of the feet by springs to enable the 
doll to advance step by step with a soft and elastic walking so that the 
doll looks like a walking baby. The movements of the human legs in any 
walking, jogging, or running action of course involve bending of the legs 
at the knee joints. While the doll supported upon a wheeled hobby horse in 
Douglas et al. U.S. Pat. No. 3,475,857, the doll supported by a wheeled 
frame in Paluck U.S. Pat. No. 1,684,287 and the doll supported by the 
child playing with it in copending Terzian et al. U.S. patent application 
Ser. No. 07/646,167 have hinged or pivoted knee joints, the self-supported 
walking dolls, do not have hinged knee joints. In addition to the 
movements of the legs themselves, coordinated movement of the torso, head 
and arms is also required in order to most realistically simulate human 
movement in a walking, jogging or running doll. There remains a need for a 
self-supporting ambulatory doll having motor driven legs which are 
themselves articulated for pivotal movement and which cooperate with other 
articulated portions of the doll to simulate walking or jogging in a 
realistic manner. 
SUMMARY OF THE INVENTION 
The present invention is concerned with providing a doll with motor driven 
articulated legs to cause the doll to walk or jog in a realistic manner. 
The foot or ankle, knee and hip joints are each pivoted and operated by 
linkages to produce a realistic articulation of each leg as the doll walks 
or jogs. In addition, the doll's torso, head and arms pivot in cooperation 
and synchronization with the movement of the legs to enhance the realism 
of the movement of the doll. Two speed operation of the doll provides for 
selective walking or jogging operation and electronic speech is 
coordinated with the selected speed.

DETAILED DESCRIPTION 
Referring now to the drawings in which like parts are designated by like 
reference numerals throughout the several views, FIG. 1 shows a doll 20 
having a torso 22 which includes an upper neck and shoulder end 24 and a 
lower pelvic and hip end 26. Disposed in the chest area of torso 22 are a 
series of apertures 28. Carried atop neck and shoulder end 24 of torso 22 
is a head 30. Conveniently, head 30 is provided with a mouth 31, nose 32, 
eyes 33 and hair 35. Doll 20 also includes a pair of right and left arms 
36R and 36L, respectively, carried by torso 22 adjacent neck and shoulder 
end 24. A pair of right and left legs designated generally 40R and 40L, 
respectively, each include a respective upper thigh portion 42R and 42L, 
an intermediate calf portion 44R and 44L and a lower foot or shoe portion 
46R and 46L. 
Torso 22, which is substantially hollow, is formed of a front shell part 48 
and a back shell part 50, as is best shown in FIG. 3. Apertures 28 are 
formed in and extend through front part 48. Included within torso 22 is a 
battery box 52 having an inner wall 53 and an upper wall 54. Battery box 
52 may be formed as part of back shell 50 and houses five 1.5 volt AA 
batteries 55. Access to battery box 52 is provided by a removeable cover 
56 in back shell part 50 of torso 22. Cover 56 includes a conventional 
resilient latch 57 to secure cover 56 to back part 50. 
Extending upwardly from top wall 54 of battery box 52 is an elongated 
mounting post 58 having an aperture 59 extending through the post 
generally transverse to its elongated direction. Extending inwardly from 
inner wall 53 of battery box 52, toward from torso shell 48, are a pair of 
laterally spaced apart, opposed channel members 62. Disposed above channel 
members 62, and also laterally spaced apart, are a pair of forwardly 
projecting abuttment members 64. Generally laterally centrally disposed on 
inner wall 53, and also extending forwardly, is a mounting boss 66. 
Each of front torso shell 48 and back torso shell 50 are conveniently 
formed with series of inwardly extending bosses for securing the two torso 
shells and for mounting various other parts. For ease of illustration, 
most of such bosses, the construction and use of which is known in the 
mechanical doll art, have been omitted. However, there is shown, adjacent 
the pelvic and hip area 26, an apertured boss 68 extending inwardly or 
forwardly from back shell 50 and an elongated boss 70 extending inwardly 
or rearwardly from front shell 48. Both of bosses 68 and 70 are generally 
centrally disposed with respect to the right and left side of the torso, 
and are substantially coaxially aligned. Apertured boss 68 has an internal 
wall 72 effectively dividing boss 68 into an inwardly facing bore 74 which 
receives the free end of boss 70 and outwardly directed bore 76 through 
which a securing bolt or screw 78 may be inserted through wall 72 and into 
boss 70. 
Carried within torso 22 is a gear box 80 that includes apertured pivotal 
mounting sleeve 82. The inner diameter of the aperture of sleeve 8 is 
sufficiently large to rotationally receive boss 70 to mount gear box 80 
within torso 22 for limited pivotal movement about the coincident axes of 
bosses 68 and 70. A DC motor 84 is carried by gear box 80 disposed 
generally below battery box 52. Motor 84 has an output shaft 86 to which 
output pinion 88 is secured for rotation with the output shaft. 
Gear box 80 has an aperture 90 in its forward face for receiving a press 
fit shaft 92. Also included in gear box 80 is an apertured boss 94 for 
receiving a press fit shaft 96 substantially parallel to shaft 92. Mounted 
for rotation on shaft 92 is an integral, coaxial gear 98 and pinion 100. 
Mounted for rotation about the axis of shaft 96 is an integral, coaxial 
gear 102 and pinion 104. Also mounted for rotation about the axis of shaft 
92 is an integral, coaxial gear 106 and face cam 108. As is best 
illustrated in FIG. 3, motor output pinion 88 is in driving engagement 
with gear 98. Pinion 100 is in turn in driving engagement with gear 102 
and pinion 104 is then in driving engagement with gear 106. Accordingly, 
face cam 108 is rotated by motor 88 at a slower speed through the speed 
reducing gear train 88, 98, 100, 102, 104 and 106. Face cam 108 includes a 
generally centrally disposed, somewhat triangularly shaped, socket 110. 
Formed around socket 110 is an irregularly shaped cam groove 112. Both 
socket 110 and cam groove 112 are laterally symmetrical about a diameter 
through face cam 108. 
Also mounted for rotation on shaft 92 is an eccentric 116 which has a 
somewhat triangularly shaped projection 118 that fits into and engages 
socket 110 in face cam 108. Projection 118 is on the rearward face of 
eccentric 116. On the forward face of eccentric 116 is an inner annular 
groove 120. Eccentric 116 is eccentrically mounted for rotation on shaft 
92. Extending inwardly from approximately the navel region of front torso 
shell 48 is a blind bore boss 124. One end of a pin 126 is press fit into 
blind bore boss 124. The free end of pin 126 fits into and engages annular 
groove 120 of eccentric 118. Thus motor 84 through gear train 88, 98, 100, 
102, 104 and 106 plus the engagement of projection 118 in socket 110 and 
pin 126 in annular groove 120, will cause limited side to side pivotal or 
rocking movement of torso 22 with respect to gear box 80 about the 
coincident axes of bosses 68 and 70. 
Extending laterally outwardly from gear box 80 are opposed, respective 
right and left, stub shafts 130R and 130L, respectively. 
Each of legs 40R and 40L are of similar construction. Accordingly, for ease 
of illustration, certain details of the same or mirror image parts are 
only shown and described with respect to one leg, it being understood that 
for each of the individual components expressly shown and/or discussed 
with respect to one of the legs, there is a corresponding component for 
the other leg. 
Upper thigh 42R comprises an outer thigh shell 140R and an inner thigh 
shell 142R. Extending inwardly from outer thigh shell 140 is a socket 144R 
which includes three, integrally formed generally equally spaced apart, 
apertured mounting bosses 145R. Also inwardly extending from outer thigh 
shell 140R is a boss 146R. Extending inwardly from inner thigh shell 142R 
is a boss 148R that aligns with boss 146R when mating thigh shells 140R 
and 142R are placed together. 
Intermediate calf portion 44R is similarly comprised of an outer shell 150R 
and an inner shell 152R. Adjacent the upper end of shell 150R is a 
recessed portion 154R from which extends an apertured boss 156R. Adjacent 
the lower end of outward calf shell 150R is an inwardly extending, 
generally semi-circular ledge 158R. Inner calf shell 152R has a recess 
160R adjacent its upper end and an apertured boss 162R that extends in 
toward the center of the doll. In addition, like calf shell 150R, calf 
152R also has a semi-circular ledge 164R extending into the inside of the 
calf portion. 
As is perhaps best shown with respect to left leg 40L in FIG. 2, when upper 
thigh shells 140L and 142L are assembled about assembled calf shells 150L 
and 152L, inwardly extending bosses 146L and 148L fit into the apertures 
of respective bosses 156L and 162L to serve as trunnions for pivotal 
mounting of intermediate calf portion 44L with respect to upper thigh 
portion 42L. 
Loosely fitting over the lower end of each of intermediate calf portions 
44R and 44L is a respective shoe 46R and 46L. As with the legs themselves, 
each of the shoes comprises an assembly that is similar to the other shoe. 
Thus, right shoe 46R has an upper shoe 166R, a lower shoe 168R and a 
surface contacting, generally high coefficient of friction, pad 170R. 
Spaced apart along a generally central longitudinal axis of lower shoe 168 
and projecting upwardly from the upper surface of lower shoe 168 are a 
pair of apertured bosses 172. Disposed adjacent the front atop the upper 
surface of lower shoe 168 is a bracket 174R having a pair of opposed 
laterally extending pins 178R. Preferably integrally formed with upper 
shoe 166R and projecting downwardly into the interior of the shoe adjacent 
its toe portion are a pair of spaced apart mounting brackets 180R. Each of 
brackets 180R has a notch adjacent its free end that fits over a 
respective one of the pins 178R. Accordingly, upper shoe 166R is connected 
to lower shoe 168R for pivotal movement of the upper shoe and lower shoe 
relative to other about a lateral axis adjacent the toe end. Pad 170R is 
secured to the underside of lower shoe 168R by a suitable, conventional 
adhesive or the like. 
Attached to lower shoe 168R by suitable, conventional threaded fasteners 
184 extending through apertured bosses 172R is a shoe hinge block 186R. As 
is perhaps best illustrated in FIG. 11, shoe hinge block 186R includes a 
pair of spaced apart, upwardly extending walls 188R and 190R. A pair of 
aligned apertures 192R extend through walls 188R and 190R as do a pair of 
aligned apertures 194R that are spaced apart from apertures 192R. 
Carried within leg 42R is a parallelogram linkage assembly comprising an 
inner elongated linkage member 198R and an outer elongated linkage member 
200R. Adjacent the upper end of inner linkage member 198R is a transverse 
bore 202R. Spaced forwardly from transverse bore 202R is an inwardly 
directed extension 204R and projecting forwardly from adjacent the 
innermost end of extension 204R a pin 206R. At the lower end of inner 
linkage member 198R is a transversely extending apertured boss 208R 
extending transversely to the general direction of elongation of linkage 
member 198R. Between its upper and lower ends, inner leg linkage 198R has 
a generally "Z" shaped body 210R with walls 211R and 212R defining a 
generally "Z" shaped channel 213R with a pair of spaced apart, generally 
parallel channel portions 214R and 215R connected by an intersecting 
intermediate channel portion 216R. 
Outer elongated linkage member 200R is also generally "Z" shaped and also 
has an extension 218R angling rearwardly adjacent its lower end. There is 
a transverse aperture 219R adjacent the free end of extension 218R. 
Adjacent the upper end of outer linkage member 200R, and more particularly 
adjacent the rearwardmost portion of the upper end is an transverse 
aperture 220R. Spaced forwardly of aperture 220R, but still adjacent the 
upper end of outer linkage member 200R is a slot 222R that is open at one 
end. The generally "Z" shaped body portion 224R of member 200R is both 
configured and dimensioned to fit, for limited up and down movement, 
within "Z" shaped channel 213R of inner linkage member 198R. Thus, body 
portion 224R has a pair of spaced apart, generally parallel portions 225R 
and 226R connected by an intersecting intermediate portion 228R. Each of 
portions 225R and 226R nest for sliding movement in a respective one of 
channel portions 214R and 215R of inner linkage member 198R. Intermediate 
portion 228R, which nests in intermediate channel portion 216R, is 
significantly narrower than channel portion 216R to allow for up and down 
movement of outer linkage member 200 with respect to inner linkage member 
198R. 
A right thigh plug 230R includes a central sleeve 232R and an annular 
flange 234R having three, generally equally spaced apart, apertures 235R 
extending through the flange. The portion of sleeve 232R projecting 
outwardly of flange 234R fits into and is received in socket 144R and each 
of mounting apertures 235R aligns with one of apertured mounting bosses 
145R. Accordingly, right thigh plug 230R may be secured to outer right 
thigh shell 140R by suitable fasteners 236 which are shown in FIG. 2 with 
respect to the left leg. 
Sleeve 232R, or more particularly, the portion projecting inwardly from 
flange 234R fits into and is received in bore 202R of inner leg linkage 
198R. Thus, inner leg linkage 198R is mounted for pivotal movement about 
the axis of sleeve 232R with respect to thigh 42R. Projecting inwardly 
from flange 234R is an integrally formed pin 238R, which is best shown in 
FIGS. 8 and 12. Pin 238R is disposed between two of the mounting apertures 
235 and fits into and is received in slot 222R of outer linkage member 
200R. Adjacent its upper end outer leg linkage 200R is mounted for pivotal 
movement with respect to gear box 80 on stub shaft 130R for rotation about 
stub shaft 130R which is rotationally received in aperture 220R. 
The lower end of outer linkage member 200R fits between spaced apart walls 
188R and 190R of shoe hinge block 186R and is mounted for pivotal movement 
with respect to the shoe hinge block. A pin 240 is press fit into aperture 
219R and is received for relative pivotal movement in each of aligned 
apertures 194R. Similarly transverse boss 208R of inner right linkage 
member 198R fits between the spaced apart walls 188R and 190R of shoe 
hinge block 186R and is also mounted for pivotal movement with respect to 
the shoe hinge block. A pin 242 is press fit into aperture 209R and is 
received for relative pivotal movement in each of aligned apertures 192R. 
Thus, with outer linkage member 200R partially nestably received in 
channel 213R of inner leg linkage 198R, the respective upper and lower 
ends of each of the inner and outer leg linkages are attached for pivotal 
movement with respect to gear box 80 and shoe hinge block 186R for 
separate but related pivotal movement. 
With the components of shoe 46R assembled and mounted through hinge block 
186R, to inner and outer linkage members 198R and 200R, respectively, each 
of inwardly directed ledges 158R and 164R are proximate but spaced from 
the outer faces of sides 188R and 190R to limit any side to side movement 
of shoe 46R with respect to the intermediate calf portion, as is best 
illustrated in FIG. 2 with respect to the left calf 44L and shoe 46L. When 
assembled, each of the shoes, or more particularly the bottom surfaces of 
pads 170R and 170L are slightly angled to be higher at their outer edges 
than they are at their inner edges. 
A cam follower link 250 has an aperture 252 that fits over boss 82 to mount 
link 250 on gear box 80 and permit relative pivotal movement of link 250 
with respect to gear box 80. Angling upwardly from aperture 252 is a 
finger 254 that has, at its upper free end, an inwardly projecting pin 256 
that is received in cam groove 112 of face cam 180. Thus, as face cam 108 
is rotated, cam follower link 250 will be driven in a predetermined 
oscillating pattern about the axis of bosses 82, 70 and 68. Extending 
inwardly from each lateral edge of cam follower link 250 is a open ended 
slot 256R and 256L. Each of slots 256R and 256L receives a respective one 
of pins 206R and 206L. Thus, as cam follower link 250 is driven in its 
predetermined oscillating pattern, the engagement of, for example, pin 
206R in its respective elongated open ended slot 256R will cause the 
respective inner linkage 198R to pivot about the axis of a thigh plug 
230R. Left leg 40L will be similarly driven in an alternating, generally 
one hundred eighty degrees out of phase, movement relative to right leg 
40R. 
As a result of the parallelogram action of inner and outer linkage members 
198R and 200R, respectively, as inner leg linkage 198R is moved upwardly, 
a shoe or foot 46R will advance forwardly substantially parallel to the 
surface on which doll 20 is supported. Because of the engagement between 
pin 238R and slot 222R of outer linkage member 200R, thigh plug 230R and 
hence assembled thigh shells 140R and 142R will be pivoted about the axis 
of the thigh plug. Forward and upward pivoting of leg 40R will result in 
pivotal movement of thigh 42R with respect to calf 44R in a manner similar 
to that of the relative pivotal movement of corresponding parts of the 
human leg. 
Mounted for pivotal movement with respect to torso 22 is a swing support 
bar 260 which includes a generally centrally disposed bore 262 that fits 
over boss 66 on back wall 53 of gear box 52. Thus, swing support bar 260 
is mounted for pivotal movement about the axis of boss 66. Disposed spaced 
laterally apart, approximately equidistant from bore 262, and projecting 
upwardly, are tabs 264. At its lateral ends, swing support bar 260 depends 
downwardly and then extends rearwardly to form levers 266R and 266L. 
Each of arms 36R and 36L have an arm mounting plug 270. Extending outwardly 
from the center of plug 270 is a radial finger 272 at the free end of 
which is an inwardly extending pin 274. Arm mounting plug 270 is inserted 
in an opening at the shoulder end of each of arms 36R and 36L and so 
engages the arms as to normally maintain frictional driving engagement 
between the plug and the arm. However, the engagement between each arm and 
its respective plug also permits relative rotational movement between the 
arm and the plug should an excessive force be applied to the arm by the 
child to avoid change to the driving mechanism within torso 22. 
Plug 270 has a annular groove 276 that permits rotational mounting of the 
plug, and of course the affixed arm, in an opening formed by the mating 
torso shells 48 and 50. The dimensions and relative coefficients of 
friction between the opening in the torso shells and the annular groove 
276 of the plug permit relatively free pivotal movement of the arms with 
respect to the torso generally about an axis extending from one side of 
the torso to the other side of the torso. As is perhaps best illustrated 
in FIG. 2 with respect to left arm 36L, lever 266L is disposed immediately 
above and in engagement with pin 274 such that pivotal movement of swing 
support bar 260 causing lever 266L to move downwardly will pivot arm 36L 
upwardly and forwardly. When bar 260 swings to the other side and lever 
266L moves upwardly, arm 36L will pivot back downwardly and rearwardly as 
a result of gravity. 
Fitting through an opening formed by the assembled front and back torso 
shells 48 and 50, respectively, adjacent upper neck and shoulder end 24, 
is a neck swing member 280 that fits over and is mounted upon upwardly 
extending mounting post 58. Neck swing member 280 has a pair of aligned 
transverse apertures 28 extending through it that align with aperture 59 
through mounting post 58. A pin 284 fits through aligned apertures 282 and 
5 with the pin being press fit in mounting post aperture 59 and received 
in each of apertures 282 for relative pivotal movement. Therefore, neck 
swing member 280 pivots about the axis of pin 284 relative to mounting 
post 58. Neck swing member 280 includes a forward, downwardly depending 
bar 286, the lower edge of which is proximate, or even in contact with the 
upper edges of tabs 264 on swing support bar 260. At its upper end, neck 
swing member 280 has a bifurcated barbed stem 288. Generally disposed 
between apertures 282 and bar 286 are a pair of spaced apart rotational 
stops 290. 
A neck plug 292 fits over neck swing member 280 and is retained against 
removal by bifurcated barbed stem 288 while being mounted for relative 
rotation about a generally vertical axis. On its bottom edge, neck plug 
292 is provided with a depending arcuate projection 294 that is disposed 
between stops 290 The arcuate length of projection 294 is less than the 
distance between stops 290 permitting limited rotational movement of neck 
plug 292 relative to neck swing member 280. Head 30 which is conveniently 
made of vinyl or the like and is relatively flexible is force fit over 
neck plug 292 and retained o neck plug 292 in frictional engagement for 
rotation with the neck plug. 
As torso 22 is pivoted or rocked from side to side with respect to gear box 
80 as a result of the rotation of motor 84 transmitted through the 
previously described drive mechanism, head 30 will also be caused, by the 
rocking movement of torso 22, to swing or rock from side to side. At the 
same time that head 30 rocks from side to side about the axis of pin 284, 
and as a result of the side to side rocking, head 30 will, because of its 
mounting for limited rotational movement, also rotate from side to side 
about a generally vertical axis as limited by projection 294 engaging 
stops 290. 
In addition to enhancing the overall articulation of the doll as it walks 
or jogs to more realistically simulate the motion of the human body, the 
side to side movement of the head assists in shifting the weight of the 
doll initially off of the forwardly moving leg and then back onto the 
moving leg as the bottom of the shoe contacts the surface on which the 
doll is walking. In addition, as head 30 rocks from side to side, 
depending bar 286 of neck swing member will contact tabs 264 of swing 
support bar 260 to pivot swing support bar 260 about the axis of boss 66. 
As previously described, the pivoting action of swing support bar 260 will 
drive the arms in a back and forth swinging movement in coordination with 
the movement of the legs to further enhance the realism of the 
articulation. 
As a variation, rather than using the side to side rocking movement of head 
30 to pivot swing support bar 260, a driving linkage (not shown) could be 
connected between swing support bar 260 and the previously described 
mechanism directly driving the pivoting of torso 22 and the articulated 
movement of legs 40R and 40L. 
Disposed immediately behind apertures 28 in the chest region of front torso 
shell 48 is a speaker 300 which fits into a recess formed by a circular, 
inwardly projecting rim 302 that is integrally formed with front torso 
shell 48. Speaker 300 is maintained in place within rim 302 by abuttment 
of the free ends of members 64 projecting from rear wall 53 of battery box 
52. Received in the opposed grooves of spaced apart channels 62 is a 
printed circuit board 304 of a type known in the talking doll art so that 
doll 20 may electronically speak various preselected phrases in a 
seemingly random manner. 
A multi-position switch 306 is mounted adjacent the upper back of the torso 
with an actuator 308 extending out through an opening provided in back 
torso shell 50 for access by the user. Through suitable wiring (not shown) 
switch 306, motor 84 and batteries 55 are connected in a conventional 
manner known to those skilled in the art to provide power. Two of 
batteries 55 are used to drive the speech electronics. Of the remaining 
three batteries, two are connected to the motor whenever switch 306 is 
turned on, while the third of the remaining three batteries is connected 
to provide additional power to the motor when the switch is in a 
particular on position. With the motor powered by two of batteries 55, 
doll 20 walks and when the addition power of the third battery is added, 
the motor rotates at a faster speed and doll 20 jogs. When switch 306 is 
in the "walk" position, the phrases spoken by the doll will relate to 
walking and when switch 306 is in the additional power, "jog" position, at 
least some of the spoken phrases will relate to the doll moving at a 
faster pace. 
While a particular embodiment of the present invention has been shown and 
described with one possible variation or modification, further variations 
and modifications will occur to those skilled in the art. It is intended 
in the appended claims to cover all such variations and modifications as 
fall within the true spirit and scope of the present invention.
