The invention relates to improvements in ap
paratus for play and sport in which a movable
carrier for one'or more persons is suspended by
ropes or belts winding and unwinding them
5 selves alternately on wheels connected with one

10 in the U. S. Patent No. 1,991,459.
The invention has for its object to provide de
vices of this class having mechanical or manual
means for winding directly or indirectly the belts
supporting the carrier on their respective wheels,
15 until the carrier has reached’its highest position
0r any desired height, whereupon the elements
`driving the shaft of the flywheel 'and the wheels
carrying the winding means are disconnected,
permitting said carrier to descend by its own
20 weight and making it ascend again as the belts
wind themselves in a contrary direction ‘on the
wheels continuing to rotate incident to the
momentum of the rotating flywheel, such vertical
reciprocating movements of the carrierV being
25 continued until brought to a stop by inertia of the
ñywheel, `or by braking.
It is another object of the invention to 'provide
means to permit a free and uniform play of the
belts supporting the carrier at their point of
30 connection to their Wheels, so asto reduce to a

rier may be removed. >To _the remaining upper
bar may bel attached some gymnastical appara
tus, such as the rings 65 shown in Figure 4, in
order to execute gymnastic exercises during the
reciprocating movements of the carrier.
In the apparatus illustrated in Figure 8, use is
made of pedals for effecting the initial ascent of
the carrier. In this apparatus, two vertical sup
ports 66 duly braced carry at their upper ends a
horizontal shaft 61 provided on'one end with a,
iiywheel 68 with its corresponding brake 69 and
towards the center with two conical gears 18 and
two flanged wheels 1| connected to the belts 12.
The gears 18 engage other conical gears 13 se
cured to the upper ends of vertical bars 14 pro
vided with longitudinal slots 15 and slidably supported in upper brackets 16 fastened to the sup»
ports 66 and lower brackets 11 mounted on the
base of the apparatus. The lower-extremities of
the bars 14 rest on the ends of centrally pivoted
levers 18 and 18a, one of which (18a) is provided
20 with a sidewardly extending pinv 19, whilst the
other lever 18, with its extremity bent downward
in form of a Z, catches from below the opposite
lever 18a carrying the pin 19, as shown in Figures
9 and 10. The pin 19 is detained by a catch 88
pushed forward by a spring 8 I, whereby the levers
18 and 18EL are maintained in the position shown
in Figure 8 with their 'outer ends raised and sup
porting the bars 14 in a position in- which their
upper gears 13 engage the gears 18 of the shaft 61.
Slidably mounted on the bars 14 are the tubes
82 united by transverse tubes 83 providing a car
rier frame suspended from the lower ends of the
belts 12. On the lower tube 83a’re mounted the
seats 84 and below this tube,*sustained in the
Ci: Ul center by a support 85, are mounted the pedals
86, the ends of which carry the worm wheels 81
engaging other Worm wheels 88 mounted loosely
on the bars 14, below the tubes 82. The worm
wheels 88 engage with an inwardly extending p-in
40 the slots 15 of the bars 14, so as to transmit their
rotation to them, enabling at the same- time said
worm wheels to ascend and descend along the
bars 14. The two sets of worm wheels 81 and 88
are housed in casings 89 fixed to the tubes 82
45 and shown in dotted lines in Figure 8.
As the persons occupying the seats 84 move
the pedals 88, the worm wheels 88 are rotated and
communicate their rotation to the bars 14 as
described. The gears 13 connected to said bars
rotate the gears 18 and consequently the shaft
81, the flywheel 68 and the wheels 1|, whereby
the belts 12 are wound on said wheels 1| and raise
the carrier 82--83 with the persons sitting on it.
As this carrier reaches its highest desired posi
:à Si tion, an arm 98 extending from the upper part
of said carrier strikes a stop 9i on a rope 92 at
tached with its upper end to a spring 93 suspend
ed from the bracket 18, and with its lower end
to the outer extremity of the lever 94, the op
posite extremity of which, pushed upwardly by a
spring 95 stronger than the spring 93, engages
from above the pin 19 of the lever 18a. As the
rope 92 is pulled upward by the arm 98 strik
ing the stop 9|, it pulls down the opposite end
~65 of the lever 94 and this end first slides down
along the inclined surface of the upper part of
the catch 88 (Figure 1l), disengaging the pin
19, and immediately afterwards bears against
an inclined projecting surface 88a provided trans
versally on said catch and pushes the latter back
ward, freeing the pin 19 from engagement with
said catch. The weight of the bars 14 on the
ends of the levers 18 and 18a depresses these
levers (Figure 9) and as the bars 14 descend,
75 their gears 13 are disengaged from the gears 18.
The carrier 82--83 then slides down along the
bars 14 without the pedals being moved and con
tinues its vertical reciprocating movements until
stopped by inertia. Shook absorbers in form of
springs 96 supported on the lower brackets. 11
and surrounding the bars 18 receive the impact of.
the carrier in case of rupture of one or both
belts 12. '
For returning the levers 'i8 and 'i8a to their
former positions, with the bars 14 raised and the 10
gears 18 and 13 engaged, the rope 92 is pulled
upward. whereby the inner extremity of the lever
94, being in the position shown in Figure .l0 after
having returned from the position of Figure 9,
engages the pin 18 and pushes it down, together
with the levers 18 and 18a, until said pin is caught
again under the catch 88.
For applying the brake 69 to the flywheel 68
during the reciprocating motions of the carrier
S32-_83, another rope 91 has been provided, con 20
nected with said brake 89 and passing between a
set of three rollers 98 extending from a casing 99
attachedv to one of the tubes 82, the braking
effect being obtained by shortening said rope 91
through displacement of the middle roller by 25
suitable means |88 against the fixed rollers.
‘In Figure l2 has been shown a device by means
of which the belts. supporting the carriers in all
of the embodiments shown may be lengthened or
shortened. It is advisable, for instance, to dis 30
pose of a reserve length of belt in case it should
break vat its point of attachment to its corre
sponding wheel, where it is most likely to wear
out. The device consists of a short length of
tube I8! loosely mounted on the bar to which 35
the lower extremity of the belt is attached, and
provided with means such as collars, screws etc.
to secure it rigidly to said bar. Around this outer
tube |8| is placed and clamped a collar |82
formed of two parts and having an opening at 40
its center within which a certain length of the
belt is wound around the tube |8i, this belt pass
ing afterwards alternately `through a series of
slots provided in an extension formed on one
part of the collar l82 and being pressed against 45
one of the solid parts of said extension by a
transversal metal strip l 84 attached by screws |85.
A preferred mode of fastening to their respec
tive wheels all of the belts supporting the car
riers is shown applied to the wheels 52 of Figure 50
4., in which is shown the end of the belt riveted
to a bent metal strip through which passes a
bolt |81 crossing the wheel. Back of this bolt
there is a recess in the cylindrical middle portion
|86 of the wheel, on which the belt is wound, so 55
that as the direction of rotation of the wheel is
reversed, the end of the belt may freely turn on
its bolt without being bent at this place.
Obviously, changes in the details of construc
tion may be made without departing from the 60
spirit of the invention, and therefore I do not
wish to limit myself to the specific constructions
shown and described.
