planatory of a variety of paths which the toy may
be caused to follow.
Referring to the drawings, and more particu
larly to Figs. 1 through 9, the toy comprises a
vehicle body B normally running upon front
wheels F and rear wheels R. The vehicle is pro
pelled by a suitable motor such as the springmotor
M, which is preferably geared to one only of the
rear wheels R in order to assist turning of the toy.
10 The toy is‘further provided with a cross wheel W
point 30, and the inner end of which is secured
to a main stem or winding stem 32. Stem 32 is
preferably connected to axle 20 through an ap
propriate train of step-up gearing. In the pres
ent case, stem 32 carries a gear 34 meshing with
a pinion 36 mounted on an intermediate shaft
38 and turning with a gear 48 which in turn
meshes with a pinion 42 (Fig. 7) mounted directly
on rear axle 20.
The motor is wound by means
of a conventional key having a square hole di 10
preferably located intermediate the front and
_
mensioned

by a hole 44 in body M, as is best

‘.a suitable ratchet may be disposed between the
The movement of cross wheel W may be obtained
periodically in response to drive by the aforesaid
motor M, and the character of movement ob
tained may be controlled by a suitable manually
movable control member C.
.
The vehicle may run on the front and rear
wheels as shown in Fig. 1, and this may for conVenience be referred to as the “normal” opera
tion of the vehicle. When the cross wheel W is
25 depressed, the front wheels F are elevated slightly
from the running surface, and the toy then runs
on the cross wheel W and the rear wheels R, as
shown in Fig. 2, and this may, for convenience,
be referred to as the “turning” operation. It
30 should be understood, however, that the toy may
travel on either a straight or a curved path dur
ing its “normal” operation, this being so because
the front wheels may be ?xed in any one of a
plurality of angular or steering positions, as is
35 clearly indicated in Fig. 3 by the arrows A and B
marked on the top. The angle through which
the vehicle is turned when in the “turning”
position of Fig. 2,~may be varied‘by ‘?xing the
cross wheel W in one of a plurality of angles or
40 steering positions, indicated by the numerals I
and 4 marked on the bottom of' the toy, .as is
indicated in Fig, 3. By suitably positioning the
control member C, the cross‘ wheel W may be
caused to remain elevated “as in Fig. 1, or to re
main lowered as in Fig. 2, or to be periodically
lowered at short intervals, or ‘to be lowered at
short intervals and additionallyv lowered for a
longer time at longer intervals.
Considering the arrangement in greater detail’
50 the body of the toy is made up of .a bottom or
chassis plate l2 and a top 14. The radiator simu
lation l6 may be made of a separate piece of sheet
metal. The parts l4 and I6 are secured together
by appropriate tongue and slot connections and
55 together form an upwardly convexed cover or
housing which is secured to the bottom l2 by a
series of tongue and slot connections [8 extend
ing entirely about the periphery of the bottom, as
is best shown in Figs. 3 and 4. Inasmuch as the
60 operating mechanism of the toy is mounted en—
tirely upon the bottom or chassis. member I2, the
said mechanism is fully exposed when the upper
parts I 4 and I6 are removed, as shown in Figs. 4
through 9.
'
Referring now to these figures, the rear wheels
65
R are mounted on an axle 20. Only one wheel,
in this case the wheel 22,»is secured to axle 20,
the other wheel 24v being freely‘rotatable on the
axle. It will be noted that wheel 22 is the outside
wheel when the toy is turning on cross' wheel W
(this construction helps insure relatively sharp,‘
turning of the. vehicle) .
'
'
.
The motorM is here illustrated as a spring
motor comprising a main spring 26, the outer end
75 of which is secured to the motor frame 28 at the
motor and the wheels, and in the present case
pinion 36 has a hub which passes freely through.
gear 40 and which on the opposite side of gear
40 carries ratchet wheel 46. This ratchet wheel
cooperates with a dog 48 pivotally mounted on 20
gear 48. The parts are so faced that the ratchet
turns freely past‘the dog when the motor is be
ing wound, but carries the dog and gear 40 with
it when the motor is unwinding.
In order to limit the speed of the vehicle, the
motor may be provided with suitable governor
mechanism, and in the present case this em
ploys a special train of step-up gearing, the gear
40 meshing with .a pinion 50 which in turn drives
a gear 52 meshing with a pinion 54, which in turn
drives a gear 56 meshing with a pinion 53
mounted on the governor shaft 68. Shaft 60 car
ries an ‘eccentrically disposed weight 62 which
functions to limit the unwinding speed of the
motor. The operation of the toy may be con»
35
trolled by a stop lever 64, the lower end of which
is pivotally mounted on the motor frame, as
shown at 66 in Fig. 7, .and the intermediate part
of which may be moved toward or away from the
eccentric weight 62, as will be clear from inspec
tion of Figs. 4 and 7. The upper end of lever
64 projects through a suitable slot in the top of
the vehicle body, as is. clearly shown in Figs. 1
and 2. With lever 64 in the position shown in
Fig. 2, the'motor is freed for operation, whereas
with lever 64 in the position shown in Fig. 1, the
motor is locked. The eccentric weight 62 func
tions not only as a governor, but also as part of
the stop mechanism of the toy.
The front wheels F are mounted on an axle
68 journalled in ?anges ‘l8 and ‘(2 turned up
wardly from bottom plate I2. Flange 10 has
a hole receiving axle 68, as will be clear from
inspection of Fig. '7, while flange 12 is provided
with an elongated slot .14 best shown in Fig. 6.
Slot ‘M is enlarged at its ends to form detents 16
and 18 (see Fig. 6), and axle 68 is normally
pressed upwardly by a leaf spring 88, one end of
which is secured to plate [2 at 82, and the other
end 84 of which bears upwardly against carrier
86, the forward end of which receives axle 68. 60
The purpose of carrier 86 will be described sub
sequently, but for the present it may be observed
that the carrier is ?anged upwardly at its side
edges 88 and 90 and that flange 88 is apertured
to receive axle 68, as is best shown in Fig. '7, 65
while ?ange 90 is slotted at 92 to receive axle 68,
as is best shown in Fig. 6. Because of slot 92,.
there is no interference with steering oscillation
of the front axle as between the positions shown
in solid and broken lines in Fig. 3. Speci?cally,
in the present case the detent 16 is so located
that axle 68 is maintained at right angles to the
longitudinal axis of the vehicle; hence in the
position shown in Fig. 4, the toy runs on a straight
3
2,124,302
line.‘ When, however, the ‘axle is moved until
received in detent 18 (see Fig. 6), the front wheels
are shifted to the position shown in broken lines
in‘Fig; 3,.and the toy follows a curved path. The
wheels are readily shifted between the positions
‘designated- A and B in Fig. 3, by seizing and mov
ing, the same manually.

The cross wheel or turning wheel W is mounted
on, an axle 94, one end of which may,if desired,
be, prolonged to form a handle 96. The axleis
carried in‘ the side walls 98. and I00 of a suitable
U-shaped support I02, the top or closed. end, of
which is secured to carrier 86, as by the useof
tongue and slot connections I04. Wall 9,8,is pro,
115. vided with a hole receiving one end of axle 9.4,
while wall I00 is provided with an, elongated .slot

are. enlarged to form’ detents J08 and _| I0,.and'
axle 94, is normally urged upwardly by the lower
end‘ II2 of a wire spring theupper end‘ N4 of

ment the angular position of the v‘cross wheel W
is readily changed from that corresponding to the
center'lineIIB of Fig.,'3~to center line H8, in
25.? Fig. 3. In the present case, this is indicated
on. the toy itself by the numerals I and 4, the
handle 96 being movable to eitherofthe numerals.
With the handle 96 at numeral 4, the wheel W

provided with a camming pin‘ I30 adapted to bear
against an arm I32 thelower end of which is
pivoted on the motor frame at I34 and the upper
end of which is turned inwardly at I36 to dis

from ,a comparison of Figs. 7 and 9, that upon
rotation of gear 34 the camming pin I30 bears
downwardly against arm I32, the end I36 of which 25;
in turn depresses carrier 06 against the influence
of leaf spring I24, and thus lowers the cross
wheel into contact with the running surface.
This operation takes place regardless of the dis
position of cam I20. Inasmuch as there is a very 301
large step-up gear ratio between the winding stem
32. and the intermediate shaft 38, the interval
between the functioningv of cam I30 is very much
longer than the interval of the functioning of
cam I20. The duration ofthe lowering of the
crosswheel depends upon the radius of camming
element I30 together with the relative disposition
of the other parts of the mechanism, and we

With the control member C in the'position
shown in Figs. 3 and 4, that is, with the surface
I52 of intermediate radius in use, the cam fol
lower end I28 of carrier 86 is disposed beneath
cam I20, but the edge I38 of carrier 86 is not dis
posed beneath the inturned lug I36 of arm I32.
In this position the cam I20 functions, but the
cam element I30 is rendered inoperative. When
the control element is turned to bring the large
radius surface I54 against the cross wheel mount,
the carrier is moved to the broken line position
shown in Fig. 4, at which time the cam follower
end I28 is moved out of the path of cam I20 and
the latter is made inoperative. When, however,
15 the control element C is moved in opposite direc
tion to bring the smallest radius surface I50 into
use, the carrier 86 is moved counterclockwise
relative to the position shown in Fig. 4, thus
bringing the same to the position shown in Fig. 5,
20 at which time the edge I38 comes beneath in
turned lug I35 and both camming mechanisms
I20 and I30 are made operative.
The three positions of control member C are
indicated on the toy, as by the numerals I, 2
25 and 3 shown in Fig. 3, the said numerals being
used in cooperation with a suitable arrow or
pointer on the control member.
The control member C may be used for still
another function, namely to hold the cross wheel
30 W permanently in lowered position.
Referring
to Fig. 8, it will be seen that the side wall I00 is
notched near its upper end at I64. If the cross
wheel is drawn down from the elevated position
shown in solid lines to the lowered position shown
in broken lines, the notch I64 reaches the con
trol member 0 and by swinging the control mem
ber to the large radius position, that is, to the
numeral 3, the edge of the control member is
moved into recess I64 and thus locks the cross
40 wheel in lowered position. At this time the cross
wheel is preferably lowered somewhat more than
the amount which it is lowered by the camming
mechanisms I20 and I30, thus avoiding any pos
sibility of recess I64 reaching the control mem
ber during the periodical depressions of the cross
wheel under motor drive.
The cross wheel may
be locked in depressed position only by manually
moving the same to fully lowered position. With
the cross wheel locked in depressed position, it
may, of course, be moved to either of the angular
A leaf spring I84secured to the bottom of the
toy at I86 bears downwardly andrnormally holds
one or the other’ of the recesses on detent I82.
The ends of the T-shaped plate beneath the
ears I66 rest directly on the marginal or higher
level parts of the bottom I88 (Figs. 3 and '1) .
The motor frame carries an idle pinion I90 so
disposed that when the reverse arm I 10 is moved
from the forward position shown in Fig. '7 to a
rearward position in which notch I18 is disposed
on detent I82, the axle pinion 42 is disengaged
from gear 40 and engages pinion I90, which in
turn is constantly in mesh with gear 40. The
direction of rotation of axle 20 is thus reversed.
To shift from forward to reverse or vice versa, 15
it is merely necessary to‘ preliminarily lift the
arm I10, thus freeing the detent, and to there
upon slide the arm forwardly or rearwardly, the
forward position corresponding to forward drive
of the vehicle, and the rearward position corre
sponding to rearward drive of the vehicle.
It is believed that the construction and oper
ation of our improved toy vehicle, as well as the
many advantages thereof, will be apparent from
the foregoing detailed description. By way of 25
review, however, the operation may be described
with reference to the schematic diagrams shown
in Figs. 10 through 21 of the drawings. If the
front wheels F are disposed in position A in Fig.
3, and if the control member C is moved to posi 30
tion’3, thus making both camming mechanisms
inoperative, the toy simply runs on a straight line,
as shown in Fig. 21. If now the front wheels are
changed from the straight line position A to the
angular steering position B, the toy describes a 35
circle of large radius, as shown in Fig. 14. In
a practical case, this diameter may, for example,
be 48 inches.
1
If the cross wheel W is turned downwardly and
locked in depressed position by control member 40
C (the control member being in position 3 and the
steering position of the front wheels being im
material), the toy will be caused to turn on a
circle of small radius. If at this time the cross
wheel is in position 4 in Fig. 3, the toy will de
scribe a small circle as shown in Fig. 15, and if 45
the cross wheel is moved to position I of Fig. 3,
the toy will describe a somewhat larger circle, as
shown in Fig. 16. In a practical case these cir
cles are 22 inches and 32 inches in diameter, re
or steering positions, thus causing the toy to de

scribe either a small or medium sized circle, both
If the front wheels are left straight, that is,
in position A, and if the control member C is
moved to position 2, thus making the cam I20
operative, the toy will describe a ?gure made up
of straight lines and sharp turns. With the cross 55
wheel in position 4, the toy will run back and
of these circles, however, being substantially
smaller than what may be obtained by use of
the steering action of the front wheels.
In order to increase the number of actions
obtainable from the toy, and because some of
the more intricate movements of ‘the toy are even
more surprising and amusing when performed
with the toy running backwardly, we prefer to
equip the toy with reversing mechanism. Refer
forth repeatedly, this ?gure ‘being indicated by
Fig. 10. The length of the straight run relative
to the length of the sharp turn may be greater
than is shown in Fig. 10. This ?gure may, for 60
ring to Figs. 4 and 7, it will be seen that the rear
axle 20 is carried in ears I 66 turned upwardly
at the outer extremities of a T-shaped member
want of a better term, be referred to as an ellipse.
If the cross wheel W is moved from position 4 to
I68, the stem I10 of which projects outwardly
through the bottom of the toy at the rear end
than 180 degrees, the toy will describe a ?gure
such as that indicated in Fig. 11, this ?gure being
thereof. The manner in which the control arm
I10 extends out of the toy will be clear from in
spection of Figs. 1, 2 and 3 of the drawings. Fig.
70 '1 shows the manner in which the upwardly curved
bottom wall I12 is slotted at I14 to receive the
arm I10. The side edges of arm I10 are turned
downwardly or ?anged at I16, and these flanges
are notched to form spaced detent recesses I 18

I80 which ‘cooperate with a detent-lug I82.
50
position I, so that the turn is 90 degrees rather
substantially a square with rounded corners.
If the front wheels are changed from position
A to position B, the “normal” running of the toy
will be on a curve rather than a straight line. 70
This curve we prefer to make in a direction op
posite to that produced by a cross wheel. The
?gure described by the toy is then made up of a
series of curves, some of long radius and some of
short'radius. Forexample, with the cross wheel 75

inediateitheifront and rear wheels, mechanism for
periodically raising (‘and lowering the cross wheel
in position 4 so that the toy turns 180 degrees,
the toy-Iwill describe a‘ triangle with curved sides,
substantially as indicated in Fig‘. 12. If, how
in order tobr'ing the same into and out of contact
with the ‘running surface, and additional mecha
nism lfor’depressing‘the cross‘wheel at longer in
ever, thecross wheel is moved‘ to position I so
that the toy turns approximatelyQO degrees, the
vehicle will describe apolygon withcurved sides,
substantially the octagonal ?gure shown in Fig.

wheels, a driving motor geared to a rear wheel in
order ‘to propel the vehicle, a cross wheel inter
10 tion I, thereby making both camming mecha
nisms 120 and I30 effective, each of Figs. 10, 11,
12 and 13 will be reproduced with the additional
mediate the frontand rear wheels, mechanism for
periodically raising ‘and lowering the cross wheel
in-iorder to ‘bring the same into and out of con
surprise element of an unexpected sharp turn by
the vehicle at relatively long intervals. This is
15
tact ‘with the‘running surface, said mechanism
being driven'by the aforesaid motor, and means 115
whereby thecrosswheel may be locked in. de
schematically indicated by Figs. l'l'through 20.
In Fig. 17, for example, the ellipse has‘superposed
thereon a complete circle of movement it being
understood that in practice the toy runs back
and forth about the ellipse anumber of times
pressedposition.
20 before the unexpected circling of the toy takes
place.‘ It will also be understood that inasmuch
' as the circling of the toy may be ‘more than 360
degrees, the vehicle may thereafter describe‘ an
ellipse in a different direction than that previ
25 ously maintained.
To produce. this ?gure, the
front wheels are put in position A, the cross wheel
is put in position 4, and the control member is
put‘in position I.
,
Similarly, in Fig. 18 the toy describes a straight
30 sided polygon with rounded corners, and at rela
tively long intervals the operation is interrupted
by an ‘unexpected turning movement of the toy.
This ?gure is obtained with the parts as previ
ously described, but with the cross-wheel changed
35 from position 4 to position I.
‘
'
Figs. 19. and 20 will be understood from ‘the
foregoing. remarks, without additional detailed
comment, it being understood that "in 'all cases
the ?gures have been somewhat idealized for‘con
40 venience and’ that the axis of veach of the ?gures
‘ may be changed by the long interval turning
movement. To produce Fig. 19, the front wheels
are changed from position A tofp'osition B, and
the cross wheel is placedin position 4; while to‘
45 produce Fig/20, the cross wheel is placed in po
sition I.
‘
v
. In this way 12 ‘different courses may be ‘de
scribedby the toy,~and ‘by appropriate use of ‘the
reverse mechanism thesnumber of operations may
be increased to 24. The variety in operation ‘is
still .further increased by-reason of the difference
in traction on various running surfaces, such as
'a rough cement floor, a polished ?oor, etc., and
also \because in practical operation the toy'occa
sionally
encounters a wall or'other obstacle, and
55
is thus de?ected from its course.» Because of the
numerous variables involved, the operationuin a
practical case'is not readily discoverable to‘be a
speci?c geometric ?gure, and the paths such as
60 Figs. :13 and-20 apparently simulate the erratic
course of an'automobile operated by a novice
or an intoxicated driver.
The Zigzag-turning
movements of the toy ‘are highly amusing to
watch, and the amusement is enhanced when
the toy is operated in reverse.
It will be apparent ‘that while we have shown
anddescribed our invention in a preferred form,
many changes and modi?cations maybe made in
the structure disclosed without departing‘from
70 .the spirit of the invention de?ned in the follow
ing claims.
