This invention relates to amusement devices.
It is an object of this invention to provide an
amusement device suitable for use on playgrounds
_
or in amusement parks..

flange whereby` it may-be bolted‘or otherwise se
cured to any desired platform. At its upper end,
the standard i terminates in a flange 3, upon
which is supported the base flange 5 of the stub
shaft il. Supported on the upper side of the base
flange is the bearing plate 6. The bolts 'i ex
tend through suitable apertures in the flange 3,

plate 5, and are provided with nuts 8, whereby
the members are rigidly and clampingly secured î.

,
These and other objects and advantages will
appear from. the following description taken in
connection with the drawing.
In the drawing:
Y
Figure 1 is an elevational View 'of the amuse
ment device of this invention, with thevweight
supporting members of two arms broken away;
Figure 2 is an elevational View, in section, of
45 the head construction of the device with the ra
dial arms thereof broken away; and
Figure 3 is an enlarged fragmentary view il
lustrative of the attachment of the weight sup
y 50
porting members to the radial arms.
Referring to the drawing in detail, and with
" .55
of the standard I may beprovided with a suitable
f.
nient within the lower sleeve i2.
‘
The upper sleeve i6 is similar tc the lower sleeve
l2 and is provided at its lower end with the rig
idly attached bevel gear i5 which is secured
thereto in the same manner in which the gear l 3
is secured to the lower sleeve i2 and Whichgear 40
,l5 is adapted to mesh with the“ gear it, as illus
trated> in Figure 2. Roller bearing members It
are disposed between the `upper portion ¿lb of the
.stub shaft ê and the inner wall of the sleeve lli
in the same manner in which they are disposed 45
between the lower portion 4a of the stub shaft i
and the inner wall of the lower sleeve i2. At
its upper end, the upper sleeve i6 is provided with
a screw-threaded cap il for protection from the
elements.
'
The lower sleeve i2 and the upper sleeve le are
I is adapted to be vertically disposed with its - each provided with a like number of radial arms.
As shown, four arms are provided on each sleeve,
lower end imbedded in the ground 2 or in con
crete, or the like cast thereabout. The lower end but it is, of course, to be understood that any suit
50
reference particularly to Figure l, the standard
able and desired number may be provided for.4 55

each. Each arm, as shown, comprises an upper
arm member I8 having its inner end welded or
otherwise rigidly secured to the supporting sleeve
and a lower arm member I9 having its inner end
secured in like manner to the sleeve at a point
substantially spaced below the point of attach
ment of the upper arm member I8 to the sleeve.
The upper arm member I8 has its outer end
welded or otherwise rigidly secured to the lower
arm member I9 at a point adjacent its end, as
shown in Figure l. The upper and lower arm
members I8 and I9 are preferably angle members
of V-section.
As shown particularly in Figure 3, the upper
15 and lower arm members I8 and I9 are provided
adjacent their connected end portions with
aligned apertures adapted to receive the eyebolt
20 disposed therethrough and provided at its up
per end with a nut 2|. Below the apertures, a
spacer member 22 of triangular section is dis
posed and cooperates with the nut 2I to secure
the eyebolt 2i! rigidly in position. Due to this
construction, it is possible to eliminate all other
means of attachment of the outer ends of the
25 upper and lower arm members I8 and I9, al
though it is preferred by us that Such members
be rigidly secured together, as by welding.
Adapted to engage the eye of each eyebolt 2l! is a
hook member 23a which has its lower end rigidly
30 secured, as by welding, to the pipe member 23
which has rigidly secured to the lower end
thereof a sheet metal stirrup 24. As shown in
Figure 3, the stirrups are each secured to their
supporting pipes 23 by means of pins 25 having
35 their ends upset, although, as will be most clearly
understood, the stirrups may be welded to the
lower ends of the pipes 23.
As shown in Figure l, each lower arm is dis
posed a substantial distance to one side of the
40 corresponding upper arm, in such manner that
an operator or rider may stand in the stirrups of
the adjacent pipes 23 and grasp with each hand
one end of the pipe 23. The pipes 23 are al1 of
equal length. If the rider places his feet in the
45 stirrups shown at the left of Figure l, the left
foot will be disposed substantially higher than the
right foot. If the rlder’s full weight is then
shifted to the higher left foot, the upper arm will
be drawn down` toward the lower arm at that
50 point, so that the sleeves I2 and I6 will be re
volved about the stub shaft 4 for substantially 180
degrees, at which point the left foot of the rider
will be lower than the right foot. If the weight
is then shifted from the left foot to the higher
55 right foot, the sleeves I2 and I6 will be again
revolved through 180 degrees and the rider will
have returned to his original position and the
leithand- stirrup 24 will be substantially above
the righthand stirrup 24, as seen at the left of
60 Figure l.
Due to the provision of the antifriction means
in the operating head of the device, the swing or
amusement device may be operated by a single
rider of very slight Weight, such as a small child.
65 The number of arms provided on each of the
sleeves l2 and I6 may be varied as desired and,
where the device is made substantially large, it
may, of course, be desired that a substantial
number of arms be provided. However, due to
70 the simplicity of the design, the device may be
made substantially small and only a pair, for
instance, of arms provided on each sleeve. vThe
device may be operated by a single rider or pas
senger or by any number, up to and including the
75 number of arms provided on each sleeve I 6.
While each of the arms has been shown and
described as provided with a stirrup for sup
porting the weight of the rider, it is, of course,
to be understood that suitable manually engage
able members may be provided at suitable dis
tance from the ground, whereby the passenger
may suspend himself from these members by
grasping them with his hands and shifting his
weight successively from one hand to the other.
This arrangement is particularly desirable for
the exercising and development of certain arm,
shoulder and back muscles, and also the develop
ment of the chest, the abdomen and muscles of
the arms and legs.
It will be understood that the above-described 15
structure is merely illustrative of the manner in
which the principles of our invention may be
utilized, and that we desire to comprehend within
ourinvention such modifications as come within
the scope of the claims and the invention.
