Abstract: A walking spring device having two or more distinct walking springs. Each of the springs is initially located in parallel side-by-side relation, and has a first and a second longitudinal end. The second end of a first of the springs is rigidly connected to the first end of the adjacent spring. In use, the first end of the first spring is deflected to cause the spring to undergo the known "walking" motion to a lower level, such as an adjacent stair step. When the second end of the first spring is drawn to the next level, the rigid connection causes the first end of the second spring to also be drawn to the next level. This in turn causes the second spring to undergo the known "walking" motion. The second spring will then continue this motion to the next level yet, and then cause the first spring to follow. This alternating process is repeated through the length of the stairs.

Abstract: A yo-yo having a pair of rotation bodies spaced from each other by a shaft, with the shaft means having a string connected thereto. Mechanisms are provided between the shaft and the rotation bodies such that: the shaft is fixed with respect to the rotation bodies as the string is unwound and the yo-yo travels downward; the shaft my rotate with respect to the rotation bodies for a selected number of rotations when the string has been completely unwound; and the shaft is fixed with respect to the rotation bodies after completion of the selected number of rotations and may therefore rewind the string to return the yo-yo to the user's hand. This mechanism may take various forms, including gears, locking tines, and tape reels.

Abstract: A light socket having a standard contact and switch arrangement for standard operation with three-way incandescent light bulbs. In addition to the standard main switch, the socket also includes a secondary mode switch operatively connected to the appropriate terminals such that placing the mode switch in a first position will provide proper operational sequence with a three-way light bulb, while placing the mode switch in a second position will provide the proper operational sequence for a one-way light bulb. This mode switch may also be provided in an adapter which is formed to be received within the receptacle of a standard three-way light socket, and which also includes a standard receptacle for the receipt of the light bulb.

Abstract: A flying amusement device including first and second rotary elements separated by a hub. Each of the rotary elements includes a set of lift members which provide lift in a common direction when the device is rotated about the hub. A length of flexible line is connected to the hub and wound thereabout prior to use. The device is held in the user's hand with the free end of the flexible line connected to the user's throwing hand. The device is then thrown outwardly from the body of the user with a snapping motion of the wrist to impart rotation to the device. This rotation produces lift, and further rotation is imparted to the device due to the device unwinding from the flexible line as it travels away from the user. Upon fully unwinding the flexible line from the hub, the continued rotation of the device causes the flexible line to be rewound upon the hub, thus drawing the device back towards the user.
