of the tie member, for the purpose hereinafter described.

On each tie member 25 is positioned a passenger carrier 30 which can rotate about the tie members 25 as an axis. Each car is held in place on its tie member by means of brackets 3E having a depending flange 32 forming a slot into which the tie member 25 fits. These brackets are attached to the under side of the car and are located adjacent each end of the car, fitting snugly over the tie member 25 betweenv the collars 26, the collars preventing the cars from sliding longitudinally. The slot formed by the bracket and ilange 32 is preferably curved to t the f contour of the tie member 25. The tie member is positively held within the bracket by means of a pin 33. On its outer edge the car 30 is provided vvith a single bracket 34 to which is attached a freely rotating wheel 35 riding on the second circular track I1. The car is thus supported at three points; namely, the bracket 34,-

and the two brackets 3l.

In Fig. 6 is shown an alternative form of arrangement of the two tracks. In this form the sweeps 22 ride on the outer track 5t. A bracket 55 (corresponding to bracket 3l) is located toward the center of each end of the underside of the passenger carrier 313. These are held in place on tie member 2.5 by means of pins and collars in a fashion similar to that shown in Fig. 2. Although the center of gravity ofthe passenger carrier 3l) is thus somewhat inward of bracket 55, the effect of centrifugal force during the operation of the device is to cause most of the weight of the passenger `carrier 3Q to rest on the brackets 55.

The inner track in this case is designed to prevent movement in either direction. A wheel 54 on a bracket 53 rides between the two flanges 53 of the track'5l.

Referring again to Fig. l,`the passenger carriers may be driven in two groups, one group associated through its sweeps with freely rotating member 2l and the second gro-up associated through its sweeps 22 with a second member 4|, also freely rotating around shaft 2B. Member 2l is provided with two vextending arms 38 through holes in which. the shaft 2li extends. Member 4l is provided with a single arm 42 fitting between arms 38 and also provided with a hole In this way `the'two members 2! and Il! can rotate independently of each other. within the limits that the passenger carriers fill of thetwo groups do not collide with each other.

By the arrangement hereinafter described, the two groups of passenger carriers are driven at different rates of speed. The group of cars at the bottom of the inclined circle will travel at a higher rate of speed than those at the top. Due to the fact that the carriers yare constantly traveling around the circle, each of the two groups will alternately travel the fastest, so that the average speed of the two groups is the same. Thus neither group will ever collide with the other group, provided the diierence in speed at the top and at the bottom is properly chosen. In this arrangement, in order to provide for the greater centrifugal force at the bottom than at the top of the inclined circle, the passenger carriers are maintained at a greater angle to the horizontal at the bottom than at the top, as clearly shown in Fig. 1.

The two groups of carriers are driven at different rates of speed by a special form of clutch located between the driving mechanism and the driven mechanism. The driving mechanism comprises a member 43 also freely rotatable on shaft 20. Rigidlyattached to this member are radially extending spokes 44, attached at their outer ends to a circumferential member or wheel 45. Depending from the under side of wheel 45 are a plurality of hooks 46 provided with V- shaped notches in which ride a driving cable 4l. The driving cable is driven by any suitable sort of prime mover (not sho-wn). The outer surface of the wheel l5 frictionally engages with shoes 48 which in turn are attached, in the manner hereinafter described, to the sweeps 22.

To each sweep 22 is attached a bracket 49 provided with a cross-arm 50. At each end of the cross-arm 53 there is attached a link 5i, extending parallel to each other and each attached at its opposite end to the shoe 48. Also attached to the shoe 48 is a light tension spring 52 extending to the cross-arm 50 of the neXt adjacent sweep. The links 5I are of such a length that, when there is frictional Contact between wheel 45 and shoe 48, links 5l will extend at an angle therefrom. The direction of this angle is such that the sweeps 22 are always in advance of their corresponding shoes Ml. This is shown in Fig. 5, where the direction of rotation is indicated by an arrow.

In operation, initial contact between the shoe i8 and the wheel 45 is secured by means of the spring 52. As the sweeps and carriers are moved on the upward side of the circle this contact tends to become more secure, due to the weight of the sweeps and carriers, which exert a moment of force inwardly against the wheel 45. This position can be visualized by turning the drawing (Fig. 5) one-quarter turn counterclockwise, so that the left-hand margin of the page becomes the bottom. As the sweeps and carriers approach and reach the downward side of the circle (visualized by turning the drawing, Fig. 5, one-quarter turn clockwise, so that the right-hand margin of -the page becomes the bottom), the weight of sweeps and carriers .no longer remains effective. In this position, in fact, the weight of the sweeps and carriers, together with centrifugal force, pulls shoe 48 away from wheel 45 against the slight tension of the spring 52. Thus the carriers and sweeps are allowed to travel faster than wheel 45 until their maximum speed is attained at the bottom of the circle. As the sweeps and carriers travel on the upward side and the speed of sweeps and carriers drops to that of wheel 45, contact between shoe 48 and wheel 45 is again established, and the cycle is repeated.

It has been found that the most practical arrangement with this variable speed travel is to have the carriers in two groups. A single group, however, can be operated equally well, although the full benefits of the device will not be realized thus. In addition, more than two groups can be accommodated provided the apparatus is constructed on a suiciently large scale.

As many other modications obviously may be made, the invention is not intended to be limited said passenger carrier is at all times at an angle inwardly inclined to thelvertical.
