.- A1iplication flled Nov ber s, 192s.v s riai noanaese- The general object of the invention is to,

6 provide a rotary ;amu"sement" device including a plurality of suspended swings whlch, not only swing outward from their points of suspension, but also travel outwardly and upwardly together withtheir points of suspension under the influence of centrifugal force, thus giving the occupa'nts'of theswing a novel and exciting thrill.

A'more particular object is to provide an attachment which may be attached to the 'endsof the radial arms of an amusement device of the rotary swing type, by means of which attachment additional swings may be suspended between the conventional swings of the device, so that such additional swings may, not only swing outwardly from their points of suspension, but also may swing outwardly and upwardly together with their points of suspension under the influence of centrifugal force.

V Other objects and advantages will appear hereinafter as the description progresses.

The invention is illustrated in the annexed drawing which forms a part of this specification and in which, i

Fig. 1 is a perspective of a rotary swing of the captive aeroplane type embodying my invention. 7 r Fig. 2is a side elevation of my attachment shown attached to the outer end of a radial arm of a rotaryswing. V

Fig. 3is a transverse vertical section taken on line 33 of Fig. 2. 7

Corresponding reference characters designate the same parts in all the figures.

In Fig. 1 I have illustrated a rotary swing of the conventional type, comprising a tower structure 1, a vertical shaft 2, extending upwardly through the top of said tower and journaled in a bearing 3'in the upper end 15 of the tower, a spider 4 comprising a hub 5 and a plurality of arms 6 extending radially from said hub which hub is secured on the shaft 2 and rests upon the bearing 3, anda plurality of swings 7,. inthe form-of aeroplanes, suspended from the ends of the arms 6'by means-of cables8, each of said swings being suspended by a pair of said cables between a pair of adjacent arms.

My invention includes a track bar 10,

formed with a vertical securing flange 11 at 16 as pivots.

13. at its innerand outer ends respectively,

a; roller 14" mounted: to travel onsaid track, ashackle 15 vertically suspended at its upper end from -aj shaft'l6-on;;wh;ich said roller is ournaled, an, eye; 17: swivelly connected :at

18, to the lower end of said shackle below saidtrack bar,a pair of cables 19 and 20 suspended at their upper ends from the eye 17 andaswing 21 in the form of an aeroplane suspended from the lower ends of said cables.

The securing flange 11 is secured by bolts -22to the head 23 on the outer end of a spider arm 6, and the track bar 10 extends outwardly and upwardly at an anglefrom said securing flange. .The stops 12 and 13 extend upwardly from the track 10. The track 10 is T-shape in cross section, its verticalflange 24 extendingupwardly from its transverse flange 25 which serves to reinforce the track.

The roller 14 rests upon the upper edge of the vertical flange 2 1 of the track 10 and said roller is formed with flanges 26 and 27 at its sides ."respectively, which flanges depend below the upper edge of the, track flange 24 over the sides respectively of said flange to prevent the roller running oil the track. The shackle 15 extends downwardly past opposite sides of the track 10 and under the track asshownin Fig. 3. A swing 21' suspended from a rollerl i'on a tracklO is Iswings 7.

. When the swing is rotated all the swings 7 and 21 swing outwardly under centrifugal force from their points of suspension, the swings 21 swinging from the roller shafts As the speed of rotation of the swing increases the rollers 14 travel outwardly on the tracks 10 until arrested by the stop 13. 'The swings 21, thus not only swing. outwardly from their points of suspension,

but travel bodily outward together with their points of suspension under the influence of a supercentrifugal force, giving the occupants of the swings a novel and exciting thrill.

While'my invention is shown attached to a conventional swing it is not restricted to such use. The invention may be constructed in a device by itself and without the swings 7 its inner end and witharcuate stops 12 and It is obvious that variation and modifications of the invention maybe made without departing from the spirit of the invention.

Having thus described my invention, I claim: a a a I 1. In eombinationwith a rotary swing; ineludin a rotary arm with aheadonits outer en a track bar formed with a flange on its inner end and with stops, one at. its

outer end and another nearits inner end, said flange being bolted to said head with the track bar extending outwardly from said arm, a roller mounted totravel on said track bar between said stops, a swing, and means for suspendlng sa1d swing from sald roller.

2. In combination with a rotary swing including a rotary arm, a track bar formed with a stop at its outer end and a stop at its inner end, means for seeuringsaid track bar at its inner end to the outer end of said ro- RICHARD GARVEY.
