` 9 Claims. (Cl. 272 39 This invention relates to an amusement device and more particularlyto a combination merry-go-round and Ferris wheel, and is a continuation in-part of U. S. Patent No. 2,728,574, issued December 27, 1955. i

It is an object of this invention to provide an improved means for rotating the wheel assembly of a combination merry-go-round and Ferris wheel selectively about a vertical axis and about a horizontal axis.

Another object' of this invention is" to provide a combination merry-go-round and Ferris wheel which employs a simplified means for converting the'merry-go-round to a Ferris wheel, and vice-versa.

Another object of this invention is to provide a combnation merry-go-round and Ferris wheel which utilizes a toggle actionfor converting the merry-go-round to a Ferris wheel and vice-versa.

Another object of this nvention is to provide a cornbination merry go-round and Ferris wheel which utilizes a pivoted A-frameassembly for converting the merrygo-round to a Ferris wheel, and vice-versa.

A further object of this inventio n is to provide a combination merry-go-round and Ferris wheel having an improved means for looking the seats in an uprigh't poSition for either a mer y-goround or a Ferris wheel.

Further objects and advantages of the invention will be apparent from' the following description taken in conjunction witlrthe drawings, wherein:

Referring now to` thedrawings in more detail, a base 10, of any suitable structure, but preferably an open frame member to reduce the weight of the amusement device, supports a pivoted A-frame assembly`11 and' a winch 12 adapted to operate the A-frame assembly. An L-shaped support column 13, comprising an upper leg 14 and a lower leg 15, is pivoted at the lower end of leg 15 to the A-frame assembly 11. A wheel assembly 16 is journaled to rotate on the upper end of the leg 14. A motor 17 is stationarily mounted on the upper leg 14 of thef olumn 13 and operatively connected to rotate the Patented Dec, 17, 1 957 "i cc :g: wheel assembly l. Seats 18 arejournaled inlthe outer periphery of the wheel assembly 16 by means of seat support members 19 and are also adapted to pivot to uprightpositon when the wheel assembly isin either horizontal or vertical position.

The A-frame assembly 11 comprisesa pairof

parallel brackets

20 and 21 fixed to the base 10. A pair-of braces o r

struts

22 and 23 are pivoted attheir lower ends to brackets 20and 21, respectively by pins -24 and 25.' The upper endsof,` the

struts

22 and 23 converge toward one another and are pvotally attached to lower leg 15 of the support column at 26. A second pair of

struts

27 and 28 of' shorter length than

struts

22 and 23 are pivotally attached attheir lower ends to

brackets

20 and 21, respectively, by.pins, only pin 29 appeal-ing in the drawings. The upper, ends of the

struts

27 and 28 likewise converge and are pivoted at 30 to the lowerleg 15 of support column 13,vb elow the pivotal connection 26 in Ferris wheel position. A keeper 55 is provided to alignleg 15 and

struts

27 and 28 inthe same vertical plane when the amusement device assumes a Ferris wheel position. Keeper 55 isa ,U-shaped bar, as best dsclosed in Fig. 7, which is fixed to the lower leg 15 below pivot 30. Keeper ss is adapted to abut against the

stmts

27 and 28 in vertical Ferris wheel position to restrain further pivotal movement. One end of a cable 31 is attached at the free end of the leg1 5 and is wound around the shaft 32 of winch ,12.7 The shaft 32 is rotated by means of the handle 33through worm 34 and worm wheel 35.

The'wheel assembly 16 comprises a rim 36, spokes 37 and hub 38. Thehub 38 is coaxially journaled onthe upper leg 14 of the support column 13. The motor 17 is preferably mounted upon leg 14, the plane of the motor base being perpendcular to lower leg 15. The wheel assembly 16 is driven by motor 17 through motor sprocket 39, chain 40' and hub sprocket 41.- The spokes 37 of the wheel assembly 16 are preferably slightly inclined to the vertical in merry-go-round position toreduce` the weight and strain and to better support the wheel assembly.

In merry-go-round position, the A-frame, asesmbly` 11 is collapsed upon the base 10 and the

struts

22,23, 27, and 28 lie in the same horizontal plane with leg 15 of support column 13, and the leg 14 provides a vertical axis about which rotates the, wheel, assembly 16. If the amusement device is Operating as.a merry-go-round, as dsclosed in Fig. 1, and it is desired to convert the` device to a Ferris wheel, ,handle 33 is turned to wind cable` 31 around shaft 32.015 the winchrlz. As the cable 31 is wound around the shaft32, the struts` and column begin` to unfold and .assume the position of Fig. 6. ,TheA-frame assembly 11 and the support column 13 are pivoted to each other at 26 and 30 to produce a complex toggle action.. As the cable 31 continues to wind around the shaft 32, the amusement device will assume the position of Figs. 2 and 3, where it may be operated as a Ferris wheel. For reconversion to a merry-go-round, thecable 31 is unwound until the device assumes the position of Fig. 1 again.

The structure of seat support members 19 best disa closed in Figs. 4 and 5. A spindle 42 is journaled in rim 36 by'means of roller bearings 43, or any other suitable typebearings. The., spindle 42 is retained in its bearings. by an ienlarged portion-or cap 44 integral with the spindle and located on the inside of the wheel rim 36. On the outside of the rim 36, a collar 45 is secured to the spindle 42 by means of a pin 46. Welded to the collar 45 is a socket 47 having an opening in one side in alignment with the collar to receive the fiattened end 48 of the spindle 42. The end 48 of the spindle is fiattened for a purpose later to be described,

The socket 47 is a tubular member within which slides a socket arm 49. One end of a seat arm 50 is pivotally attached to one end of the socket arm 49 by means of pin 51. The other end of seat arm 50 supports seat 18. One or more spring latches 52, preferably two, may be mounted on the outside of socket 47 and are urged into engagement with apertures 53 in socket 47 and into slot 54 of socket arm 49, when the amusement device assumes the Ferris wheel position as disclosed in Fig. 4.

In Ferris wheel position, socket arm 49 and seat arm 50 are pivoted into coaxial alignment and raised until the spring latches 52 engage the slot 54 and the pivoted end of the seat arm 50 is within the socket 47. In this position, pivotal movement between socket arm 49 and seat arm 50 is prevented and the seat 18 is locked to the seat support member 19. The seat support member 19, however, is free to rotate in the bearings 43 in rim 36 to maintain the seats 18 in a constant upright position as the wheel assembly rotates as a Ferris wheel.

When the amusement device is converted into a merrygo-round, the spring latch 52 is released manually to disengage the slot 54. The socket arm 49 slides through the socket 47 until the end of the slot 54 at the free end of the socket arm 49 engages the flat end of the spindle 48. In this position, the seat arm 50 and the pivot pin 51 are completely outside the socket 47, and the seat arm is free to pivot until it is perpendicular to the socket arm, when the rim 36 is in a horizontal position as disclosed in Figs. 1 and 5. The seat 18 will thus assume an upright position for a merry-go-round.

The entire structure of the amusement device is designed for complete portability, strength, safety, simplicity of operation, and rapid convertibility from a merry-go-round to a Ferris wheel and vice-versa.

It will be apparent to those skilled in the art that various changes may be made in the invention, without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended clains.
