The present invention relates to a looping aeroplane swing and has for its prime object to provide a swing with mechanism operable by an occupant therein to put the swing in motion and to cause it to loop about the stationary shaft mounted in a stand.

Another very important object, of the invention resides inthe provision of a swing-of this nature which will afford considerable amusement, thrills, exercise of a healthy nature and which is of simple construction, inexpensive to manufacture, strong and durable, adjustable, and thoroughly eflicient and reliable in use and operation.

5 With the above and numerous other objects in, view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as Will be hereinafter more fully described and claimed. V I In the drawings: e

Referring to the drawings in detail, it will 1.

be seen that numeral 5 denotes a rectangular base frame from which rises a stand S. which supports at the top thereof-a pair of alined relatively spaced brackets B. Supported between the brackets B is a stationary shaft 19 that is secured in position through the medium ofU-bolts 40 and held against rotation by means of lugs 41 rising from the brackets ind engaging recesses provided in the shaft 9- Shaft 19 intermediate the ends thereof is provided with a crank 7 A connecting rod;

4 is pivotally connected at its upper end to r the crank 7 by acrank pin 18. The purpose of the connecting rod 4 will be hereinafter made manifest.

Y A pair of swing supports 6 provided at their'upper ends with saddles 5', the same being in the nature of plates secured to said ends of the support and provided with antie friction bearings 67. The aforementioned saddles 5 are mounted on the shaft 19 as shown between collars 68 that are adjustably engaged with said shaft, and fixed collars 69.

Eachof the swing supports 6 have diverging portions connected at their lower ends .to the fuselage of a swing structure simulating the structure of an aeroplane. A suitable propeller 43 is mounted on the front end of the fuselage.

QPP deslgnated by the'reference character 46, and adjacent the forward end of the fuselage, there is mounted on the frame bars brackets 48 in which is journalled a rock shaft 16.

Mounted on the rock shaft 16 is a sleeve49 that is keyed to the rock shaft through the medium of a suitable set screw 50.

Sleeve 49 is provided with a rocker arm 50 and the connecting rod 4 atits lower end is bifurcated and straddles the-free end of the arm 50. The bifurcated end of connecting arm 50 as suggested in Figure 3.

Sleeve '49 on oppositesides of the arm 50 is provided with a pair of arms 3, and the arms 3 of each pair of arms extend at substantially right angles to the rocker arm 50.

Each pair of arms 3 support between their rod '4 is pivotally engaged as at 63 with the osite'frame bars of the fuselage are free ends a guide rod '21 that is provided intermediate its endswith oppositely disposed trunnions 52 rockable in the extremities of.

the arms 3. p

Each of the rod guides 21has slidable therethrough a power rod 2. On each rod 2 adjacent the rear end ofthe guide 21'is slidably mounted a sleeve 22,and a coil spring 23 is disposed about the rod 2 and arranged between the sleeve 22 and a shoulder 54 provided by enlarging the rear end of the rod 2.

Rearwardly of the shaft 16 is mounted a, fixed transverse shaft 25 that has its ends sup-c ported in brackets supported on the frame members 46. On the shaft 25 is rockably mounted a pair of levers or sticks 1, there' alined with a selected one of a series of openf ,ings 57 provided on the rear of a rod 2, a bolt 58 engaging the alined openings 47 and 57 whereby to pivotally connect the free end of the power rod 2 with its control stick 1.

Each rod 2 adjacent its rear end has adjustable thereon a saddle 8 that is retained at the desired adjustment on the rod 2 through the medium of a bolt engageable with a selected one of a series of notches 56 provided on the rod 2.

Each saddle 8 has a stud 60.rising therefrom and a foot rest 15 is rockablyengaged with the stud and retain-ed in operative engagement with the stud through the medium of a suitable lock nut 26.

Each foot rest 15 is substantially T-shaped as suggested in Figure 10 and the cross head of the foot rest at its ends has flanges 61 and 62 depending therefrom, flange 62 being longer than the flange 61- and being capable .of engaging the rod 2 for limiting swinging movement of the foot-rest bar in one direction.

Preferably, the swing or car F is large enough to accommodate two occupants. For

40 the occupants, there is suitably provided in the swing, a seat 11, and the occupants of the swing when seated, may engage with their feet, the foot rests 15 and at the same time with their hands grip a stick 1 which will extend upwardly between the legs of each occupant.

In operation, preferably two persons occupy the swing as above suggested, and with their feet push on the foot rests 15 and with their hands gripping thesticks 1 pull the sticks toward them, with the result that there is exerted on each rod 2 a push and pull and obviously by continuously alternately pushing and pulling on the sticks 1, the swing will gather momentum as it swings back and forth. As the momentum increases, the swing will be caused to move in the arc of a circle about the fixed-shaft 19. The above operation is thought apparent from the fact that an occupant or occupants by pushing with the feet on the foot-rest bar 15, and pulling the lever '1 toward him'will, through the medium of the connection between the lever 1 and the shaft 16, causethe latter to rotate in an anti-clockwise direction or toward the left in Figure 3 causing the swing body or car to swing or move toward the left in Figure 3. The lever 1 is then swung in an opposite direction, causing a reverse rotation of shaft 16 resulting in a swinging of the swing body or car toward the right there being of course at this time no push being exerted by the feet on the rudder bar 15.

As a safety means, there is provided for the occupants of the car F a suitable safety belt 12 that may be buckled or otherwise secured at its ends to the sides of the fuselage,

with an intermediate portion of the belt passing through a guide loop 13 suitably anchored to the seat 11 for position between the occupants of the swing.

As is thought apparent, saddles 8, may be adjusted relative-to the power shafts 2, and the connections between the power shafts 2' and the sticks 1 may be also easily effected to accommodate either a grown person or a small child. Furthermore, the adjustments for oneperson may be made without disturbing the adjustments previously made on the otherside of the swing for the second occupant of the swing so that if desired both a grown person or adult and a child may occupy the swing at the same time without inconvenience to either.

Of course, the swing may be controlled by a single occupant, in which case, the controls are adjusted in the same position on both sides, and in which instance, the operator would then sit between the two sticks 1 and take one stick in each hand. The foot rests 15 are then swung to the dotted line positions shown in Figure 7 and the shank portions of the foot rests thus provide a rest for the feet a of the single occupant.

The power rods 2 being slidable relative to the guide sleeves 21 will prevent the sticks 1 with which said rods are-engaged, from being forced back to such an extent asmight injure the occupant or occupants.

The rods 2 being slidable, also relieves compression strain on the connecting rod 4,. Suitable means for maintaining the movable parts in a welllubricated condition are pro vided, the hood H of the swing being easily removable to gain access to such parts of the swing as may be located under the hood. There is also provided for each of the guides 21 a suitable lubricant device 24:.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
