12 Claims.

This application is a division and continuation in part of my application Serial No. 757,687, now Patent No. 2,107,196, issued February 1, 1938.

This invention relates to amusement devices and has particular relation to devices wherein one or more passenger carriages are suspended by flexible means from an overhead support rotatable about a substantially vertical axis, in order that they may have swinging motions in vertical planes substantially radial of such vertical axis, superimposed upon their motion about the latter axis.

The present invention contemplates an improvement in such devices wherein the carriages are provided with airfoils controliable by passengers to effect oscillations or Swinging movements of the carriages in the aforementioned substantially vertical planes, during the time when the carriages are moving in circular paths about the substantially vertical axis of the support.

The airfoils are arranged in spaced relation and preferably offset in opposite directions from the center of gravity of the loaded carriages, and are connected for movement together by simple control means operable by passengers in the carriages. By such arrangement the longitudinal axes of the carriages may be maintained in tangential relations to their path of motion about the vertical axis of the support, regardless of the operated position of the airfoils. When the carriages are moving, gravity and centrifugal forces are constantly acting upon them, and a passenger in a carriage, by manipulation of the airfoil control means, may bring into play air pressures upon the airfoils which will either oppose the force of gravity and supplement the centrifugal force or supplement the force of graV- ity and oppose the centrifugal force. In this way the passenger may set up and amplify, or damp out, as he desires, oscillations of the carriage in a vertical plane which may be conceived as extending radially of and rotating about the upright axis of the overhead support, the carriage swinging about the connection to the support.

Due to practical limitations of speed, and of size of airfoils, sufiicient air forces cannot be exerted upon the latter to maintain the carriages in positions greatly different from those resulting from gravity and centrifugal forces, but by moving the airfoils between reversed operating positions at the terminal phases of oscillations of the carriages, swinging movements of large amplitude may be set up quickly in the carriages.

According to the present invention the desired combination of swinging action and motion in a circular path is obtained without appreciable twisting motions or oscillations of the carriages about axes vertical to them, which motions tend to twist the carriage supporting cables.

In order to further eliminate such twisting B motions the carriages are supported by suspension members which are spaced at their points of connection to the overhead support, and have connections to the carriage at points spaced widely longitudinally thereof. By this arrangel0 merit gravity and centrifugal force cooperate with the airfoils in maintaining the longitudinal axes of the carriages in substantially tangential relation to their paths of travel about the axis of rotation of the overhead support.

The airfoils and control means arranged according to the present invention are effectively and easily operated by passengers having no previous experience, and thereby afford to them thrill and enjoyment not available in devices of the same class but not constructed in accordance with the present invention.

These and other objects and advantages will become apparent from the following description of the typical embodiments of the invention shown in the accompanying drawing, wherein Figure 1 is a side elevation of the amusement apparatus embodying my invention. Figure 2 is a side view of one of the carriages, partly in section, showing the passenger control means associated therewith. Figure 3 is a horizontal section taken in the plane of line 33, Figure 2. Figure 4 is an enlarged view of one of the suspension hangers. Figure 5 is a top plan view of a modified form of one of the carriages. Figure 6 is a top plan view of a modified arrangement of the body air impinging elements.

Referring now to Figures 1-4, the numeral 8 indicates an upright mast having a revolving overhead support or frame preferably composed of upwardly extending radial arms 9 from which the passenger-carrying bodies or carriages are suspended so as to revolve therewith and, caused by centrifugal force, to be carried outwardly of the structure in the manner common to circle swings, The revolving overhead support may be mounted and driven in any well known manner, that shown in the drawing, by Way of example, consisting of a motor Ill and bevel gears II.

The passenger-carriages, which are suspended in suitable spaced relation about the overhead support 9, are indicated generally by the numeral 12. The carriages are suspended from the overhead support by cables I3 whose upper ends are connected to adjacent arms 9 and whose lower 55,

ends are looped, as indicated at E4, to engage midway of the top frame [2 of the carriage. To insure the carriages from turning bodily about, auxiliary cables [5 are connected at their upper ends to the cables l3 at a point approximately midway thereof, while their lower ends are connected to the top frame of the carriage. Cushion or shock-absorbing springs iii are interposed in the cable l5 so that a certain resiliency of carriage mounting is obtained. 7

The carriage I2 consists of a body portion I! having a seat [8 which may be designed to accommodate one or more passengers. At its front and rear ends the body H is provided with simultaneously-actuated, passenger-controlled means for producing a swaying or side swinging action of the carriage during its circular movement. Each of these means consists of airfoils or vanes I9, disposed centrally and vertically of the carriages and pivoted at 2! to upright posts 22 depending from the carriage frame member. 12*, as shown in Figure 2. This frame member is secured. to the floor of the carriage-body in any convenient manner, as by nuts 23 screwed to the free ends of the posts 2i, thus facilitating the ready dismemberment of the parts for shipping purposes; By preference the front vane IQ extends fore and aft of the pivot-post 2|. and is of substantially the same face area as the rear vane 20.

Means are provided under the sole control of the passenger in the carriage for simultaneously actuating, in a corresponding direction, the front and rear vanes to control the swinging movements of the respective carriages. The means for accomplishing these results preferably consists of a hand-wheel 24 mounted on a shaft 25 journaled in bearings 26 secured to the body I! of the carriage l2. Fixed to the shaft 25 is a pulley 21 about which is wound a cable 28 which passes outwardly and downwardly over idler pulleys 29 and is then connected to one end of a crank arm 30 fixed to the front vane 9 at its lower end. Connected to the other end of the arm 311 is a tie bar 3| extending rearwardly under the carriage and joined at its other end to a crank arm 32 secured to the lower end of the rear vane 20. It will be seen from the foregoing that the vanes or airfoils I9, 20 are simultaneously actuated in a corresponding direction whenever the handwheel 24 is actuated by the passenger to accordingly swing the carriage 12 either inwardly or outwardly or up or down from its normal riding position and thereby give the passenger the accompanying thrill of side-swinging or swaying the carriage out of its normal course defined by the revolving overhead support.

The swinging motion of the carriage may be greatly amplified by reversing the position of the airfoils at times corresponding with terminal phases of the oscillations, so that the air pressures may act upon the airfoils to supplement the rate of swinging motion previously set up.

If the control wheel is held stationary the oscillations will gradually be damped out by air resistance. They may be quickly damped out by reversing the position of the airfoils at the terminal phases of the oscillations to cause the forces acting upon the airfoils to resist the phase of motion which is to follow.

As will be apparent from Fig. 2, the airfoils l9 and 2B are so spaced in relation to their areas and the center of gravity of the carriage (when the latter is carrying passengers), that the air forces acting upon them will constitute parallel forces tending to move the carriage laterally, Without exerting any appreciable force tending to turn the carriage about an axis vertical to it.

The effective center of the total airfoil area (approximately at the point indicated at C in Fig. 2) is preferably in approximate alignment with the center of gravity of the carriage (when loaded with passengers) and a point midway between the two points of connection of the cables l3 to supporting arms 9, further reducing any tendency of the air forces acting on the airfoils to turn the carriage about an axis vertical to it.

In the modified form of the carriage shown in Figure 5, the seats 33 are arranged in tandem relation and the impinging members or vanes 34, 35 are disposed vertically in series or in the plane of the carriage and pivoted at 36 thereto for lateral swinging movement. Three of such vanes are disposed in parallel relation at each end of the carriage, the central vane 34 being joined by cross links 31 to the side vanes and foot levers 38 being provided at each seat station and connected by flexible members or cables 39 to lugs 40 radiating from the central vane. By this arrangement, when a foot lever is moved in one direction'or the other, the front and rear sets of vanes are simultaneously actuated in a corresponding direction to control the swinging movements of the carriage.

In Figure 6 the air impinging elements 4| are disposed at opposite sides of the body 42 in vertical planes and pivoted at 43 to swing vertically and simultaneously in response to actuating the foot lever 44, the latter being connected to said elements in substantially the same way as in 1.;
