Abstract: A steerable roller skate of the shoe skate variety has an elongated one-piece sole plate in the form of an open topped dish with a bottom wall, a side wall and a continuous rim, outturned along the long sides thereof and, in the preferred form, rising from the toe end toward the heel end to join with a heel-less shoe sole uninterruptedly around the sole. A pair of support shaft bosses extend upwardly from the bottom wall, each with an open-ended vertical passage and each crowned with a lip around the passage defining a non-circular socket to receive the head of a bolt-shaft. The underside of the bottom wall has a pair of bearing tongue seats formed in it. Neither the shaft bosses nor the seats have a reentrant surface with respect to the adjacent surfaces of the bottom wall.

Abstract: In a steerable roller skate a one-piece sole plate has a bottom wall, with a pair of support shaft bosses in the bottom wall, each with an open-ended vertical passage. An elongated steel shape having internally threaded bolt-receiving spuds spaced along its length complementarily to the bosses is positioned to be coaxial with the boss openings. Shaft bolts, for mounting wheel trucks, extend through the boss passages and into threaded engagement with the spuds. The underside of the sole plate has a pair of bearing tongue seats formed in it. Neither the shaft bosses nor the seats have a reentrant surface with respect to the adjacent surfaces of the underside of the sole plate.

Abstract: A floatable toy (e.g., a toy boat) having two hulls, a frame spanning the hulls, and a container for holding a supply of water above the level of the water on which the toy floats. A discharge outlet is connected to the container at its bottom and extends downwardly below the surface of the water. A nozzle opening is provided at the bottom of the discharge outlet so as to discharge a jet of water in a generally horizontal direction thereby to impart thrust on the floatable toy. The container and the discharge outlet are rotatable relative to the frame spanning the hulls about a generally vertical axis so as to enable the toy to be steered.

Abstract: A toy driving simulator has a body in the form of a vehicle, e.g., automobile, boat, snowmobile, tank or spaceship, within which is a selectively driven belt upon which a path or paths to be followed and obstacles to be avoided are depicted. A miniature vehicle to be steered is connected to be moved laterally with respect to the belt by a manipulatable steering device. The path-displaying surface of the belt and the miniature vehicle are viewable in a mirror that is generally, but not necessarily, in the form of the inside surface of a simulated windshield.

Abstract: An illusion toy has an upper compartment in which a figure with sword or wand in hand appears to strike through a solid neck, and a lower compartment in which the mechanism for rotating the sword or wand is housed. The upper compartment has a cover on it with a hole to receive the neck. The neck has a head on its outer end, which, larger than the hole, remains on the outside of the cover. The neck can be withdrawn through the hole, and remounted at will. The mechanism includes a shaft that carries on its upper end the wand or sword, a pinion or the lower end of the shaft that is turned by an arcuate segment rack, and a spring biased overcenter mechanism to flip the sword or wand through more than 270.degree., in response to the manipulation of a handle, at such a rapid rate that the sword or wand appears to traverse an arc through the neck instead of moving in the opposite direction.

Abstract: A kaleidoscope is provided having an object enclosure containing a multiplicity of pattern producing objects mounted to one end of a tubular body member. The mounting method employed permits object enclosure rotation in two directions about the body member. Preferably, the object enclosure includes a first wall arranged in a spherical shape encompassing a chamber. A second wall is concentrically arranged with respect to the spherical shape interiorly of the chamber. The first and second walls delimit at least one compartment for the pattern producing objects. The chamber volume inboard of the second wall is visually unobstructed to permit observation along a line of sight therethrough. Consequently, two compartment segments on opposite sides of the object enclosure may be viewed simultaneously. The first wall of the object enclosure has a material thickness having first and second outboard surfaces on opposite sides thereof. One of the first and second outboard surfaces has a plurality of facets formed in it.

Abstract: A device for indicating the presence and distance required to clear a velocipede is provided which is attached easily to the velocipede, for example, a bicycle, on a frame member or a luggage carrier, the luggage carrier being mounted to a suitable structural member of the bicycle. The device includes indicating means and means for providing a storage position for the indicating means. The indicating means may be displayed on either or both sides of the bicycle. The indicating means is designed to be spring mounted to a support member attached to the bicycle frame, or to the end of a standard bicycle luggage carrier on bicycles so equipped.

Abstract: In a wheeled toy having a frame and a wheel mounted for rotation with respect to the frame, two fixed resonators are mounted on the frame symmetrically on either side of a boss projecting from the frame, the resonators having a supporting platform, and a clopper is provided, including a pair of percussion units, a bridging piece between the percussion units and pawls projecting outboard of each of the percussion units, the percussion units engaging the supporting platforms of the resonators, and the bridging piece spanning between and being wedged between the surfaces and a facing surface of the boss, and a multiplicity of spaced trip means are carried by the wheel and positioned to engage both of the pawls when the wheel is rotating.
