One objectv of the invention is to furnish a
toy of the character described having improved
means for ?ight of the propeller in a path aligned
with the handle of the device or at an angle
thereto, at will.
A particular object of the invention is to fur
nish a game of skill, Wherefore the toy includes
improved means. such that the angle of ?ight of

exempli?cation of the invention.

the propeller is partly controlled by the tension
exerted on a draw string that causes rotation of
the propeller.
Since the propeller is initially carried by a
rotary head which is subject to friction, the speed
of rotation varies with the tension of the draw
string subject to the effects of friction. Hence
the toy thus permits a degree of control of the 20

portion I6 and a lower headed end portion l-l.
Carried by the upper end of the element I5
is a bearing or tube l8. formed at its upper end
with a flat head it. Said bearing may have a
similar head 20 at its lower end, or such head
may be formed on an adjacent portion of the
element It. The bearing l8 may be rigidly se
cured to the latter as by press ?tting thereinto

The skill of the operator

FI‘he advantages of the invention as here out
lined are best realized when all of its features
and instrumentalities are combined, but useful
in Fig. 3; the rod is normally frictionally re
tained at that elevation. Initially, the pulley
2| is aligned with the handle but when the draw
string 22 is pulled to rotate the pulley, the ten
sion exerted causes the rod t5 to resiliently bend
or de?ect in the direction of the pull on the
draw string as shown in Fig. 3. Thus the axis
of the pulley and its propeller is inclined, and as
rotational speed increases, the propeller ?ies oil
into space at a like angle. The angle of ?ight
relative to the handle is determined by two fac
tors: the length of the section of the element
I5 which is external of the handle at the top
thereof, as at 26 and hence laterally unsup
at variable angles, the said stem portion com
prising a, bearing for the rotatable element where
by the latter is held against movement along
the member.

The draw string tension may be varied as be
tween a hard, steady pull or an extremely power
ful jerk which may achieve maximum ?ight. In
a cheap construction such as is used in a toy,
there is naturally a fair amount of friction at
the bearing surface and this will afford a meas
ure of retardation to permit the operator to
gauge the tension applied.
