of radiating arms 10, which may be of anyt
suitable form, as for example that shown
better by Fig. 2. .
These arms 10 in my preferred sample
5 construction comprise a pair of companion
pieces 11 and 12 (see Fig. 2) which are
spread at their inner ends and provide in-
turned portions 13 and 14 which are piv-
otally mounted in lugs 15 and 16 forming
10 part of the hub. At their outer ends, these
pieces 11 and 12 run parallel and are spaced
apart, this being conventionally done by
means of a block 17 and the end 18 of the
vane supporting rod.
15 The radial arms carry an interlocking
device at their outermost extremities. That
is to say, a plate 19 having side wings 20,
and an intermediate aperture 21 is secured
to the outermost extremity of each of the
20 radiating arms in such manner that the re-
cess 21 will lie between the parallel extreme
ends of the members 11 and 12 forming
part of the radiating arms. It is to be noted
that the side wings 20 turn upwardly, as
25 shown more clearly by Fig. 1, the purpose
being to enable the end of a spring to ride
under either of these wings and snap into
engagement within the recess 21. This,
however, will be more clearly apparent pres-
30 ently.
Links 22 are pivotally connected at their
ends between the parallel extremities of the
companion members of the radiating arms.
See in this connection Fig. 1. It will be
35 perceived that this device affords a yield-
ing arrangement for the framework com-
posed of the connecting links 22, the radi-
ating arms and the extensible vertical shaft.
The vanes are preferably mounted to
40 swing on the links 22, and to that end, I may
provide a tubular member 23 to which the
vanes are affixed by means of the brace mem-
bers 25. This construction forms a hinge,
so to speak, for the vanes, and as will be
45 seen, the vanes project inwardly toward the
extensible shaft and are maintained in ver-
tical position by their mountings.
I have resorted to a peculiar means of re-
stricting the movement of the vanes with
50 respect to the rest of the apparatus. Thus,
I have arranged a spring 26 so as to inter-
vene between the vanes 24 and the radiat-
ing arms. As will be seen more clearly by
referring to Fig. 2, this spring 26 has its
55 end 27 interned and seated within one of
the vane braces 25 in such manner as to
form an interlocking joint. This inter-
locking is permanent in the ordinary use of
my invention. After coiling around the
60 sleeve 23, the spring turns upwardly, as in-
dicated at 28,. and this upturned portion is
arranged to snap into engagement with the
seat 21. from the above description, it will
be noted that the vanes are flexibly mounted
65 by virtue of their. spring connection withthe radiating arms, and in consequence, these
vanes are enabled to spring under the con-
joint influence of the wind and the springs
into their most effective positions, as illus-
trated by Fig. 2.. 70
In case the wind should be very violent,
the speed of rotation of my apparatus will
not become excessive, for the outer features
of my apparatus will tend to move out-
wardly under the influence of centrifugal 75
force, with the result that the end hubs 8
and 9 will be brought together, thus tilt-
ing upwardly the extremities of the radiat-
ing arms, so as to release the springs 28 from
their engagement within the recess 21. .8
This having been done, they will be freed
and will no longer be effective under the in-
fluence of the wind, and the excessive move-
ment of the apparatus will not occur. So
soon as the movement has diminished and 85
has become entirely normal, the ends of the
springs will again become engaged in the
recesses and the vanes will be brought into
effective position once more.
It will thus be perceived that I have suc- go
ceeded in achieving the several objects and
ends in view, and that my invention is note-
worthy for a characteristic simplicity and
effectiveness of action. Furthermore, the
few parts of which my device is composed 95
are none of an involved individual design,
but on the contrary, are of such nature as
enables them to be made with the greatest
of facility by the various appliances com-
mon to shops. 100
Inasmuch as the special features of this
invention could be very readily modified in
form and utilized in many seemingly differ-
ent constructions, I desire the foregoing dis-
closures to be regarded in an illustrative, 105
rather than in a limiting sense, and I also
desire it to be understood that the language
of the following claims is to be interpreted
as covering the generic and specific features
of this invention and all statements of the iio
scope thereof, which form the aspect of the
prior art,_ might be said to fall therebe-
tween.
I claim:
1. A device of the nature disclosed com- 115
prising in combination, an upright extensi-
ble shaft, an upper and lower series of arms
radiating from the upper and lower ends of
said shaft, a series of vanes normally in op-
erative position pivotally carried by the 120
outer ends of said arms, means interposed
between said vanes and said arms to restrict
the swing of said vanes, and means enabling
said means to become inoperative under ex-
cessive speeds. 125
2. A device of the nature disclosed com-
prising in combination, an upright exten-
sible shaft, a, spring arranged to maintain
said shaft in extended condition, an adjust-
able means for positively limiting the ex- 130
