A spring to store energy; A mass to provide the impulse (a hammer) A release mechanism that releases the stored energy at a consistent point in the travel of the body; A provision to reset the device after actuation
After insertion, male strikers may be disengaged by twisting the inlet so as to activate a spring-release mechanism. The flat outlet ports ensure no injury if a patient or health-care worker should fall into the wall; a consideration when dealing with the mentally ill or those with neuro- or musculodegenerative disorders.
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
The spring release was used in the past almost universally on trailing-type ploughs with one to three or four bottoms. It is not practical on larger ploughs. When an obstruction is encountered, the spring release mechanism in the hitch permits the plough to uncouple from the tractor.
Some pullback motors, usually intended for racing in pairs, have used a catch and release mechanism to retain their springs. These may be wound separately, then launched together by releasing their spring triggers. Darda use such a mechanism for their Stop'n'Go motor. [4] This is pre-wound, then releases automatically when shunted from behind.
A coil spring is a mechanical device that is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded.
However, whereas the spring or the weight provided the motive power, the pendulum merely controlled the rate of release of that power via some escape mechanism (an escapement) at a regulated rate. The Smithsonian Institution has in its collection a clockwork monk, about 15 in (380 mm) high, possibly dating as early as 1560.
