ROUNDABOUT.

Application filed February To all whom it may concern:

Be it known that I, OSCAR F. OLsoN a citizen of the United States, residing at Bethlehem, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Roundabouts, of which the following is a specification.

This invention relates to amusement devices and particularly to devices for giving patrons a ride of a novel character.

The principal object is to provide a device of this nature in which a variety of different circular motions may be imparted to the passenger carrying car.

Another object is to produce a novel and efficient means for effecting these various motions automatically.

Another object is to produce a device of this nature which shall be simple of construction, comparatively inexpensive to manufacture, and highly efficient for the purpose for which it is intended.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is an elevation view of the improved amusement device- Figure 2'is a vertical sectional view of the same.

Figure 3 is a vertical sectional view taken at right angle to Figure 2.

Figure 1 is a bottom view of the carriage.

Figure 5 is a top view of the carriage.

Figure 6 is a sectional view through the car and carriage.

Like characters of reference refer to like parts in all views.

Referring in detail to the drawing, 10 represents a motor which maybe of any suitable type for the purpose and which effects operation of a shaft 11 carrying a mastergear 12 to which may be carried a plurality of wheels 13. Each of the wheels 13 is connected to identically similar devices, and only one of these connected devices is shown in the drawing, and as all are precisely alike only one is here described, although it is to be understood that it-is intended to drive several of these devices from a single motor source.

11, 1922. Serial No. 535,841.

A circular track is provided comprising an inner rail 14 and an outer rail 15 and upon these rails are mounted respective Wheels 16 and 17 carrying a cage structure which will presently be described. The inner wheel 16 is connected by ashaft 18 with the respective gear 13.

The cage structure comprises a pair of hubs 19 secured to the respective wheels 16 and 17 and supporting a plurality ofbars 20 which are curved so that said bars and hubs together form a globular cage, which rides upon the tracks 14: and 15 and is rotated by means of the shaft 18.

Inside this cage there are provided a pair of circular rails 21 whichare arranged parallel to each other, but at. an angle ,tothe axis of rotation of said globe which angle is other than a right angle, the preferred form being an angl of from 10 to 80 from the transverse plan of the axis of rotation of the cage. It will be seen that if a carriage is mounted on the tracks 21 and gravity keeps the same at the bottom of the cage, then upon rotation of the cage, the car will move in the direction of the axis of rotation back and forth a distance commensurate to the distance which the tracks are deflected from the transverse plan.

Such a carriage is provided and comprises a base plate 22 inside plates 23, the latter carrying bearings for a plurality of wheels 24 which ride on the upper surface of the tracks 21 and a plurality of guide wheels 25 which bear against the inner surfaces of tracks 21 so as to prevent the carriage from slipping from the rails. At the center of the base plate 22 there is provided astub shaft 2-6 which extends downwardly from the base plat and also upwardly therefrom. The downward extension of shaft 26 is mounted for rotation in a, bearing formed in a block 27 mounted slidably on a bail 28 which is pivotally mounted concentric with the axis of rotation of the globular cage.

A passenger car 29 is provided centrally of its bottom with a bearing into which the upwardly extending portion of shaft 26 extends. The car is also provided on its bottom with a ratchet wheel 30 whereby the car 29 may be rotated on the shaft 26 by means which will now be described.

Slidably engaging the bail 28 are channel shaped grips 31 and 32 which are connected upon respective slides 33 and 34 slidably neunted on I, the base 22 of the carriage. "The block 33 carries on its upper surface a spring pressed ratchet pawl 35..

Connected to the blecli: or slide 34 is an arm 36 which carries an arcuate rack 37 meshing With a pinion 38 carried by a bracket 39. rack 40 depending from a slide block ll mounted'inthe base plate 22. The slide block. 41 carries on its upper surface a spring pressed ratchet pawl 42, the pawls 35 and 42 both engaging the ratchet Wheel From the construction above described, it Will be seen that as the cage isro'tated by means of the motor asn ill be readily understood, the carriage Will ride along the tracks 21 and owing to the angular arrangeinent of saidtracks Will take a zigzag course moving outwardly during one-halt (if the rotation and inwardly during the other half of the rotation; This turns the carriage on the axis of shaft 26 and as the. channel shaped grips 31 and 32 are held constantly in engagement With the bail 28,

o the carriage Will move relatiigely to the slides aaa'nd 34; thereby bringing the ratchet pawls 35 and H 42 into operation on the ratchet Wheel 30, the pawl 85 taking effect as the carriage is moved inwardly, and the pawiie taking effect as the carriage moves outwardly. In this manner there is obtained the following motions: (1) rotation about the motor shaft on the tracks 14 and 15, (2) movement of the carriage from side to side in the basket rotary movement of the car about the axis 26. Besides, the cage revolving about the carriage and the car gives the effect to the passenger of "another movement.

' In order to obtain easy access to the car one of the barsao is provided With'a central joint 43 Which telescopes at one end overt reduced portion of the bar, and isprovided at the other end with a slide lock 44 whereby this section of the barinay be lo ':l ed in place. l r l Vllhile I have described What I deem to i he the most desirable embodiments of invention, it is obvious that many of the details may be varied without in any Way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the Whole of my [invention limited only by' the appended claims.
