vided on the external surface of the body in
parallelism with and between the ribs 23, all for
a purpose to be described in the operation of
the invention, which is as follows:
When the body i0 is manually rolled on a sur
face so as to rotate in the direction of the arrow
26 and be guided in a straight path by the ribs 23,
the weighted member 2| maintains its depending
vertical position. The clutch formed by the pawl
10 24 and lugs 25 causes the disks IT to be held by
the weighted member against rotation with the
body. As the springs l3 and I4 are secured to. ‘
the frame H and thus rotate with the body, the '
effective result will be the twisting of the parallel '
15 stretches of each of the cords l6 so as to shorten
movement of the body on a surface is initiated;
means co-acting with the ?rst means to render
the latter inactive when the body is reversely
rotated in rolling it on a surface, whereby to
enable the body to be rolled as a free ball; and 5
means on the body for indicating the direction
of rotation of the body necessary for the ?rst
means to be active in returning the body as
aforestated.
4. A returnable toy ball comprising a rollable 10
body; a weighted member mounted in the body
to;constantly tend to maintain its position irre
spective of rotational movement of the body
about a predetermined axis; means in the body
operatively associated with the latter and mem 15
ber to store energy in the body as the latter
the lengths of the respective cords. The ends
of the spring I3 will thus be drawn towards each
rotates about said axis during rolling of the body
other or ?exed so as to load the spring in response
on a ‘surface, and to expend the energy in re
to the rolling movement of the body on the versely rolling the body when the rolling motion
20 surface.
when the rolling movement of the bodyin the
direction of the arrow 26 ceases, the springs in
tending to expand, will untwist the cords l6 and
thereby reversely roll the body so that the ball
25 will return to the location on the surface from
which motion was manually imparted to the ball.
With the ball at rest, rolling of the ball on a
surface in a direction reverse to that of the arrow
25 will render the clutch inactive, as the pawl 24
will merely click or slip by the lugs 25. The disks
_l'! will, therefore, not be held against rotation
by the weighted member maintaining its position,
with the result that the ‘cords IE will remain un
twisted and the body roll as a free ball.
5..A returnable toy ball comprising a rollable
body; a weighted member mounted‘in the body
to constantly tend to maintain its position irre
spective of rotational movement of the body
about a predetermined axis; means in the body
operatively associated with the latter and mem 30
ber to store energy in the body as the latter
rotates about said axis during rolling of the
body on a surface, and to expend the energy in
reversely rolling the body when the rolling mo
tion ?rst imparted to the body ceases; and a uni
with which an e?lcient return mechanism is asso
member and ?rst means to render the latter in
active to store energy when the'body is reversely
rotated about said axis, whereby to enable the
body to be rolled as a free ball.

6. A returnable toy ball comprising a rollable
body; a weighted member mounted in the body
to constantly tend to maintain its position irre
spective of rotational movement of the body
about a predetermined axis; a spring in the body;
and an operative connection between said mem
as desired, thereby increasing the play value of
40: the ball, while permitting the latter to be tossed,
bounced or otherwise handled, in play.
As shown in Figure ‘2, a suitable ?exible ‘rubber
?ap valve 21 is cemented to the internal surface
of the wall of the body ID to control a port 28
therein. In orderto prevent ‘excessive deforma
tion of the body when bounced, it is desirable to
place the body under slight pressure by in?ation
ber and spring byewhich the latter is caused to
be loaded as ‘the body rotates about said axis
during rolling of the body on a surface, for
operation of the spring in reversely rolling the
body when the rolling motion ?rst imparted to
the latter ceases.

7. 'A returnable toy ball comprising a rollable
path when rolledjon a surface; means co-acting
withthe body to store energy in response to rota
tive movement of the body in one direction when
body; a weighted member mounted in the body
to constantly tend to maintain its position irre
spective of rotational movement of the body
the body is rolled on the surface,’ and operable
to reversely roll the body by expending the energy
when the rolling movement ?rst imparted to the
body; and cords operatively connecting said
- body ceases; and means by which the ?rst means
is rendered inactive to ‘store energy in the body
when reversely rotated in rolling the body on a
surface, whereby to enable the body to be rolled as
a free ball.
2. A returnable toy ball comprising a rollable
35
directional clutch operatively connecting said
thereof through the port '28, the valve 21 auto
matically closing the 'port under the action of
internal pressure upon the valve.
What is claimed is:
i
1. A returnable toy ball comprising a rollable
about a predetermined‘ axis‘; a spring in the
member and spring, and adapted to be twisted to
load the spring as the body rotates about said 60
axis during rolling of, the body on a surface, for
operation of the spring in reversely rolling the
body by untwisting the cords when the rolling
to enable the body to be ‘rolled as a free ball.- ‘
motion ?rst imparted to the body ceases.
8. A returnable toy ball comprising a hollow, 65
rollable body; a bowed spring ?xed between its
ends in the body; a weighted member in the
body; and means for suspending said member
freely in order that the member will tend to
maintain its position irrespective of rotation of
the body about a predetermined axis; said
means including spaced pairs of cords connected
3. A returnable toy‘ball comprising a rollable
body; means co—acting with the body to rollably
return the latter to a-location from which rolling
at one of their ends to the free ends of the
spring, and at the other of their ends to the
member so as to become twisted and .?ex‘ the
body; means cc-actin'g with the body to reliably
return the latter to a location from which rolling
movement of ‘the body on a'surface is initiated;
and means co-acting with the first means to
render the latter inactive when the body is re
versely rotated in rolling it on a surface, whereby
a
be rolled as a free ball.
From the foregoing description, it will be mani
fest that‘ the invention provides a novel toy ball
ciated in a manner to enable its use or non-use

?rst imparted to the body ceases; and means by 20
which the ?rst means is rendered inactive to
store energy when the body is reversely rotated
about said axis, whereby to enable the body to

spring in response to rotation of the body about
said axis during rolling of the body on a sur
face, whereby to store energy in the spring,
which, is expended to untwist the cords and re
versely roll the body when motion of the latter
as ?rst rolled, ceases.
ing spaced pairs of cords connected at one of
their ends to the free ends of the spring, and at
the other of their ends to the member so as to
become twisted and ?ex the spring in response
to rotation‘ of the body about said axis during
rolling of the body on the surface, whereby to
store energy in the spring, which is expended to
untwist the cords and reversely roll the body
9. A returnable vtoy ball comprising a hollow,
rollable body; a bowed spring ?xed between its
ends in the body; a weighted member in the when motion of the latter as ?rst rolled, ceases;
and a unidirectional clutch interposed between 10

in order that the member will tend to maintain said member and the cords to enable the body
its position irrespective of'rotation of the body
about a predetermined axis; said means includ
