Abstract: A system for sound generation and noise feedback is disclosed for attachment to a bicycle training wheel. The system includes a plurality of sound generators attachable by a means for fastening to a rotatable surface of the training wheel. As the sound generators rotate with the wheel, sound is generated in proportion to the speed of wheel rotation. The sound generation system further includes a sound generator attachable to the support frame of a bicycle wheel. A clapper is pivotably attachable proximal to the sound generator, for intermittent contact with the sound generator when the clapper is engaged by one or more projections connected to, and rotated by the wheel. The generation and feedback system further includes a light generator and an electrical circuit connected to the sound generator for intermittent generation of sound and light in proportion to the rotation of the training wheel.

Abstract: An accessory which produces distinct sounds in order to alert others of the presence of a bicycle. The accessory is formed of a housing, sound producing assemblies, and a mounting system. The mounting assembly may be clamped around left or right members of bicycle forks, frame, stays, or braces. Housing of the accessory will accommodate mechanical or electronic sound producing elements which are interchangeable and may be used individually or in combination. When installed and the bicycle is in motion, a variety of sounds may be produced depending on the configuration of the sound producing components.

Abstract: A railroad car-warning bell is centrally mounted on the hub of a wheel. Three opposed cylinder housings each contain a reciprocating ball which hits an end hammer to sound the bell when the wheel turns slowly up to speeds of nominally 15 mph. At higher speeds the balls are held against the end hammers, thereby automatically shutting off the bell to prevent noise pollution. The preferred embodiment has a single cylinder mounted along a diameter of the ringing bell. Three steel balls oscillate back and forth hitting a hammer at each end of the cylinder. A dampener may be used to adjust the ring of the bell.

Abstract: A wheel activated bicycle reflector attachment is rotated with and by the rotation of the bicycle wheel, reflecting a rotating or flashing pattern of light to oncoming traffic. The apparatus is adjustable to various size bicycles by means of a telecopic shaft and a pivoted bracket. A drive wheel, supported by the bracket, is rotated with and by rotation of the rear bicycle wheel and thus rotates reflectors connected to the drive wheel. The drive wheel axis of rotation is located rearwardly of the rear wheel axis of rotation to insure constant, positive engagement with the rear bicycle wheel.

Abstract: A noisemaker for bicycles and the like includes a housing having a shoulder and a resonator plate seated in the housing on the shoulder. The resonator plate is biased against the shoulder by a compressed spring. A resonator chamber extends from the shoulder, away from the housing. Use of a camming mechanism raises the resonator plate above the shoulder and releases same as it passes so that the resonator plate is urged back against the shoulder by the spring and a surface-engaging noise and air compression noise are directed into the resonator chamber to simulate the sound commonly associated with a vehicle engine.

Abstract: A vehicle movement warning device particularly designed to deter vehicle theft by emitting a loud clatter if the vehicle is moved without authorization. Advantageously, the device also deters vehicle movement by providing a frictional impediment to movement, without damage to the vehicle. The device includes a pair of waffle surfaces, the first waffle surface being mounting to a wheel for rotation with the wheel. A releasable shift mechanism mounts the second waffle surface to the vehicle in a position for selective shifting movement into and out of engagement with the wheel-mounted waffle surface. Preferably, the shift mechanism comprises a spring biasing the second waffle surface into engagement with the wheel-mounted waffle surface and a solenoid for withdrawing and holding the second waffle surface out of engagement with the wheel-mounted waffle surface.

The detector comprises a strip mountable to a hub of the vehicle and includes a pair of legs projecting outwardly beyond the plane of the tire side wall so as to be observable when the tire is viewed in a direction transversely of the rotary axis thereof. The legs carry a light reflecting substance so as to be visible at night. A fastener is provided which enables the strip to be mounted in a central hole of the vehicle hub. The legs are configured so as to be deformed in response to engagement with an annular wall of the wheel so as to assume a condition parallel to the rotary axis of the wheel.

Abstract: A pivotal crank is positioned with respect to the output cam of a torque limiter such that upon torque limiter operation the resulting translation of the cam pivots the crank. Attached to the crank is a flag arm which is normally retained by a spring clip. Pivotal motion of the crank causes disengagement of the flag arm from the spring clip thereby indicating torque limiter operation. The flag arm remains in the disengaged position, despite subsequent absence of limiter operation, until it is manually reset.

Abstract: The disclosure teaches a novel noise making accessory for vehicles having spoked wheels such as bicycles or the like, and, more specifically, teaches such a noise making accessory which is adjustable to produce different sounds. The accessory includes a plurality of fingers which can be selectively positioned to extend into the path of travel of the spokes of one of the wheels of the vehicle. As the fingers are of different sizes, different sounds will be produced when a different one or different ones of the fingers extend into the path of travel of the spokes. The spokes can be of different lengths, widths, thicknesses, or a combination of the above. The objective of the accessory is to produce a motor-like sound.
