' 4 Claims.

This invention relates generally to an amusement deviceI and particularly kto an airplanel amusement device.

The main object of this invention is the construction of an extraordinarily simple and efficient form of amusement. device, which will give the user thrills similar to those experienced in an airplane;

'I'he second object is to produce an amusement device in which a car can be swung in a circular orbit in a vertical plane, and in which a rotating movement can be imparted to the car on its longitudinal axis while traveling about in its circular orbit.

'I'he third object is to construct a device of the type referred to which is selectively usable in a manner to permit the car to be ilxed with relation to its supporting arm, or to revolve on the longitudinal axis of the car as may be desired. I accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawings, in which:

Fig. 1 is a front elevation of the device show ing same in a rotating position.

Fig, 2 is a view similar to Fig. 1 showing the position of the car at its tlrst quarter of a revolution of travel.

Fig. 3 is. a view similar to Fig. 2, but showing the car at` the halfway position, that is, at its uppermost position of travel.

Fig, 4 is a view similar to Fig. 3, but showing the car at the third quarter of travel.

Fig. 5 is a side elevation of the device showing the parts in the position corresponding with those shown in Fig. 1.

Fig. 6 is a section taken along the lines 3-8 in Fig. 5.

Fig. I is a section taken along the lines 1-1 40 in Fig. 6.

Similar numbers of references refer to similar parts throughout the several views.

Referring in detail to the drawings, there is shown a base' I0, which may be secured to a foundation in any convenient manner. From the base I0 rises the slightly inclined mast il through whose head I2 extends the horizontal, stationary. shaft I3 upon which the arm bifurcated i4 is revolvable. vAttached to the hub I5 of the arm i4 50 is a gear I 3 winch meshesV with the pinion I1 of the driving motor I3, which is controllable from the box I 3 on the upright 23.

Secured to the stationary shaft I3 is a beveled gear 2i, which is also stationary since it is secured to the shaft I3 by means of a pin 22, and

(ci. 21a-4 6) the shaft I3 is secured to the head I2 by means of a key 23.

The gear 2| meshes with the gear 24, which is Becured'on'the shaft 25, which Journals in the bearing 23. The shaft 2 3 has formed on the en d thereof a clutch jaw 21. In alignment with the bearing 23 is a bearing 28 on whose side facing the clutch jaw 21 is formed a slot 23. Journalling in the bearing 28 is a shaft 30 whose end 3| also vJournals in the clutch jaw 21. 4On the shaft 30 is slidably -keyed a clutch Jaw 32, which can be moved into engagement with either of the

members

21 or 28 by the forked arm 33, which is pivotally mounted on the pin 3l, and may be held in any desired position by means of the bolt 35, which passes through the slot 36. A hand lever 31 is formed integral with the forked armv 33, and facilitates the movement of-the clutch Jaw 32.

On the shaft 30 is also secured a bevel gear 33,l which meshes with a bevel gear 39 on the trun- 4nion 40 of the car 4I, whose opposite end is supported by a trunnion 42. 'Ihe trunnions 40 and l2 Journal in the outermost ends 43 of the arm i4. The arrangement of thev seats 44 in the car li may of course be varied greatly without departing from the spirit of this invention.

Attention is drawn to my copending application, Ser. No. 719,874, issued Jan. 8, 1935. as Patent 1,987,004 over which this device is an improvement.

The operation of the device is as follows: Assuming that it is desired to operate the device in the manner described in myfabove identiiled application, the operator moves7 the lever 31 so that the clutch jaw 32 will engage the slot 23, the bearing 28 thereby locking the

gears

33 and 39, and preventing the rotation of the car 4i with relation to the arm I4. If, however, the car 4I is to be rotated on its trunnions 4 0 and l2, the lever 31 is moved to the position shown in Fig. 6. In this event, the shaft 25 is enabled to rotate the car li at a speed which will hold the car 4i upright in its lowermost and uppermost positions as shown in Figs. 1 and 3, and to turn it to intermediate positions as shown in Figs. 2 and 4.

It will be observed that the arm Il is in the form of a triangle, of which the car 4| forms 50 the base, which naturally provides the greatest amount of rigidity for a given weight.

While the clutching mechanism has been shown adjacent to the car 4I, it is obvious that it can be placed nearthe upper end of the drive 55 without departing from the spirit of this invention.

I claim:

1. 11n an amusement device of class scribed the combination of an upright mast. a stationary, horizontal shaft disposed at the upper end oi' said mast, a bifurcated arm having its closed end revolvably attached to said stationary shaft, a prime mover Yfor revolving said arm in a vertical plane, a car revolvably mounted on a longitudinal axis between the bifurcated ends oi said arm. said axis lying within said vertical plane, a gear secured on said stationary shaft and a gear drive meshing with said stationary gear extending to said car whereby said car will bevrevolved at the same rate on its longitudinal axis that it is revolved in said vertical plane.

2. The device described in claim 1 in combination with clutch means adapted to render inoperative the gearing for rotating said car on its longitudinal axis and to lock said car against rotation with relation to said arm.

3. A device of the class described having an A-shaped frame revolvably mounted in a vertical plane with the vertex of said frame at the axis of rotation. both arms of said frame lying within said plane, a car rotatably mounted between the outermost ends ot said A-shaped frame along the longitudinal axis of the car, said car axis lying within the plane of rotation of said i'rame and normal to the radius of rotation of said frame together with gearing for rotating said car in a manner that it will be right side uppermost in vertically opposite positions and in reverse positions in horizontally opposite positions.

4. An amusement device having in combination an upright supporting standard. a horizontal shaft disposed at the upper end oi' said standard, an arm revolvably mounted on said shaft, a prime mover: for revolving said arm, a car mounted on an axis lying within the plane in which said arm swings and normal to the radius of said arm permitting said car to rotate on its longitudinal axis and means for selectively locking said car against rotation on its longitudinal axis, or causing same to be rotated thereon in a manner that said car will be upright in its uppermost and lowermost positions.
