Weighing about 1 kg (2 lb), the clockwork torch incorporates two improvements over the clockwork radio. First, the on/off switch mechanically halts the spring mechanism from operating. Secondly, internal energy storage in a small rechargeable battery keeps the torch shining while the spring is rewound.
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo , supplying electric current to an incandescent bulb or light-emitting diode .
A clockwork mechanism is often powered by a clockwork motor [4] consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until the stored ...
Trevor Graham Baylis CBE (13 May 1937 – 5 March 2018) was an English inventor best known for the wind-up radio.The radio, instead of relying on batteries or external electrical source, is powered by the user winding a crank.
The original Baygen clockwork radio with crank in winding position A windup radio or clockwork radio is a radio that is powered by human muscle power rather than batteries or the electrical grid. In the most common arrangement, an internal electric generator is run by a mainspring, which is wound by a hand crank on the case.
A mainspring is a spiral torsion spring of metal ribbon—commonly spring steel—used as a power source in mechanical watches, some clocks, and other clockwork mechanisms. Winding the timepiece, by turning a knob or key, stores energy in the mainspring by twisting the spiral tighter. The force of the mainspring then turns the clock's wheels as ...
Automata built for the sake of art, amusement, and simulation have been described since antiquity, in cases such as Heron of Alexandria designing clockwork birds during the Hellenistic Period. [2] Leonardo da Vinci is frequently credited with constructing a mechanical lion , which he presented to King Francois I in Lyon in 1515.
The Carcel lamp of 1800, which used a clockwork pump to allow the reservoir to sit beneath the burner, and Franchot's spring-driven Moderator lamp of 1836 avoided these problems. The same principle was also used for cooking and boiling water due to its 'affording much the strongest heat without smoke'.
