Abstract: A toy vehicle has a pair of gripping tongs spring-biased open and loosely housed in a recess preferably in the underside of a housing for the toy vehicle. A pair of spaced-apart cam surfaces are located in the recess for engaging the tong arms on opposite sides of their pivot, and a manually operable lever engages and moves the pivot deeper into the recess so the cam surfaces pivot the free ends of the tong arms together against the spring bias. The cam surfaces are preferably closer to the pivot than to the free ends of the tong arms, and the tong arms preferably have shoulders slidably engaging the cam surfaces during opening and closing movements.

Abstract: An object (baton, ball, wheel, or the like) which generates a signal (visual, audio, or the like) only when in rotation and when in rotation generates a continuous signal. A power source, a first switch which assumes its ON position in response to centrifugal force, a second switch which assumes its ON position in response to centrifugal force, and means for generating a signal, connected in series are carried in the object. The first and second switches are mounted so that both are ON when the object is in rotation about a first axis, but not when it is at rest. Third and fourth switches may be placed to be ON when the object is in rotation about second and third axes at right angles to said first axis and to each other. The switches may be closed by movement of a fluid or of sliding or rolling elements.

The fore legs may be formed integrally with this second part or they may be pivotally attached thereto. In a second embodiment of the invention, the first part of the model consists of the body and arms of the rider, together with the majority of the horse, while the other part of the model consists of the rider's legs, together with the shoulders of the horse.

Abstract: Game-of-skill toy having a main frame adapted to be rotated repeatedly in a 360.degree. arc by the user which includes one or more laterally projecting support points upon which normally removable small objects, e.g., discs, are balanced and maintained in place, initially by gravity, and, during rotation of the frame, by centrifugal force.

Abstract: A rocket toy has a unitary cylindrical body with outwardly projecting fins and a partition wall across the interior near the front end. A tapered cylindrical lip projecting from the body front end receives one of two nose cones. The first, a parachute-receiving nose cone, fits loosely on the tapered lip and is held in place during forward flight by the air resistance of a forwardly facing brake surface on the nose cone exterior. A parachute, furled within the nose cone, has cords attached by an elastic band to the rocket body. After launch, as the rocket toy slows down near the apex of its trajectory, the air resistance is insufficient to hold on the nose cone. The nose cone drops away, permitting the parachute to deploy. The second nose cone fits tightly on the tapered lip and remains in place throughout the entire flight. The rocket toy is launched by the compression of air within a pair of telescoped tubes, one of which is connected to the rocket body cylindrical rear end during launch.

Abstract: A thoracic drainage device including a container for receiving drainage fluid, and a drainage tube for connecting the pleural cavity of a patient to be drained to the container, the outlet end of the tube being disposed below the level of liquid in the container to provide a liquid seal. The container includes a gas outlet for connection with the atmosphere or to a source of vacuum, and an annular defoaming member in close surrounding relation with the drainage tube and in the flow path of gas flowing from the drainage tube to the gas outlet for minimizing foam.

Abstract: The musical toy consists of a body which contains a music box movement of the "left-right music movement" type that is normally operative to produce the desired melody in either direction of rotation of its drive shaft. The movement is fixed to the interior of the hollow body for rotation therewith and means are connected to the drive shaft to hold the shaft against rotation. As a result, when the body is rotated it turns the music movement with respect to the non-rotating drive shaft and produces the desired musical melody. The melody is produced regardless of the direction of rotation of the body of revolution.

Abstract: A wheeled toy which includes a frame portion in the form of a crown for grasping by a user and for manual manipulation of the toy over a support surface. A pair of drive wheels are journalled on the underside of the frame portion for rollingly supporting the frame portion for movement over a support surface in a generally straight line, with front and rear stabilizing wheels. An impeller is rotatably mounted on the crown-shaped frame structure and protrudes outwardly therefrom at the lower marginal periphery thereof in proximity to the support surface for engaging objects on the support surface as the toy is rolled thereover and propelling the objects away from the toy. The drive wheels are operatively connected to the impeller and protrude downwardly therefrom for rotating the impeller in response to rotation of the wheel means as the toy is rolled over the support surface.

Abstract: A inflation device adapted to admit compressed gas to the interior of a balloon, and to seal that interior against the atmosphere after inflation, is comprised of a pair of circular disks in parallel alignment and in spaced relationship with respect to one another. The disks are rigidly affixed to a central shank which extends beyond one of the disks. The shank extension is bored with a passage, sealed at the far end thereof, which communicates with the annular space between the disks, by means of a radial orifice. The tubular neck of the balloon is stretched over the sealing disks, with the shank extension protruding from the opening in the balloon sheath. Upon pressurizing the passage in the shank with air or other inflating medium, that portion of the balloon stretched between the two disks distends, and permits the medium to enter the internal volume of the gas bag around the periphery of the inner disk.

Abstract: In a children's peg top including a top body having a tip whereon it can spin, an axial recess is provided in the end of the top body remote from the tip. A magnetic element carried in such recess cooperates with a magnetic element on a spinner body so that the spinner body is separably held magnetically in the top body recess. One end of each of two cord lengths is connected to the spinner body. Such cord lengths can be twisted together and then caused to untwist by drawing their free ends apart thereby rotating the spinner and top bodies.
