A compact and easily assembled merry-go-round consists of a turntable supported at its periphery upon spaced inverted casters mounted on a frame bearing, on its underside and in verticle alinement with said casters, leveling devices. The turntable is fixed at its center to a vertical driven shaft rotatably mounted on the frame and coupled to an electric motor. Simulated animals pivotally carried by the turntable nutate as the turntable rotates through a cam follower relationsip with a sinusoidal...

Apparatus for imparting an undulating motion to an amusement car unit travelling in a circular path is disclosed which includes an upper rotary hub (28) and a lower track rail (D) both of which are carried concentric about a rotary axis (X). The track rail (D) is carried adjacent the ground and supports a carrier arm (C) having a generally L-shaped configuration with one arm (48) pivotably attached to the rotating hub (28). A second cantilevered arm (50) joins the pivotably connected arm (48) at...

Portable amusement device, commonly known as "Tilt-a-Whirl", characterized by a trailer forming operative and other parts of the device, including hoisting apparatus employed during assembly and disassembly. It is designed to stow the various parts on the trailer in compact manner to facilitate transportation thereof. After disconnecting the trailer from a tractor-type truck its frame is lowered to the ground, forming a rigid central support about which the device may rotate. An entrance compart...

The device for simulating longitudinal and transverse accelerations on a vehicle compartment has a first motion level for longitudinal displacement of the compartment and, placed on top of the former, a second motion level for transverse displacement of the compartment. To simplify the construction in the interests of low production costs and to allow large mechanical loads to be applied while keeping the height of the assembly low, a pair of bogies configured at a fixed longitudinal distance fr...

A plastic ski slide comprises a rigid reinforcing support of a wickerwork of metal rods, and plastic elements fixed to said reinforcing support. The plastic elements provided with flexible, projecting thin rods are fixed with clearance with respect to each other.

In a scraper excavating apparatus, the secondary lip comprises an apron skirt which is coextensive in width with, and is of sustantially similar curvature as, the apron of the scraper; guideways which are fastened at each side of the apron and which are operable to guide vertical travel of the skirt over the lower portion of the forward, exterior side of the apron; and a suitable actuator, such as cables, to selectively raise and lower the apron skirt with respect to the apron and to selectively...

An amusement device comprises a rider propelled rotatable riding device, such as a roundabout or merry-go-round, on which one or more riders propel themselves in a circular path. The device has two concentric vertically undulating tracks of different radii, such that they constitute inner and outer tracks. The undulations preferably are 180.degree. out of phase on the respective tracks. A rotatable structure is mounted for rotation concentrically with respect to the track, and carries a pair of ...

An amusement ride of the roundabout type with a plurality of radiating arms each having an inner end connected to a central support for vertical swinging movement and a passenger carrier at the outer end. The passenger carrier is supported from a circular pathway by a wheel and cushioning assembly with the pathway including a curved jump ramp, safety bridge and landing ramp to simulate the action of a ski jump and provide a pathway closely underlying the wheel of the passenger carrier but spaced...

An airfoil for an aircraft capable of both vertical and horizontal flight has a forward fixed part, a flap part constituting the rear portion, and an auxiliary lower surface part, or foreflap, which is pivoted along its front edge near the leading edge of the fixed part and normally has its rear edge close against the under side of the flap. When the aircraft is in vertical flight, the rear flap and the foreflap extend downward and, together with the fixed part, form a rounded and faired shape t...

A seat secured to one end of a horizontal beam whose opposite end is secured to a vertical support column for horizontal rotation of the seat in a circular path, with propelling means in the form of a ringlike track, arranged beneath the seat, and having a curved upper surface forming peaks and valleys and interconnecting ramp portions. A propulsion wheel rides upon the track and is rotatably connected to the lower end of a lever connected between its ends to a pivot on the seat, so that rearwar...
