The guillotine is an engine for beheading people at one stroke. It was invented during the Middle Ages, and adopted with improvements by the National Assembly of France during the first revolution on the proposal of a Dr Joseph Guillotine who proposed its use to prevent unnecessary pain, and after whom it is named.
In this apparatus decapitation is effected by means of a steel blade loaded with a mass of lead, and sliding between two upright posts, grooved on their inner sides, the person's neck being confined in a circular opening between two planks, the upper one of which also slides up or down. The condemned is strapped to a board and rapidly moved up so as to place the neck of the condemned within the semi- circle of the lower plank, the other being raised for the purpose. On the right of the table is a large basket or trough of wicker-work for the reception of the body. Under the place where the head rests is a rectangular trough for its reception. The knife is fixed to the cap or lintel on the top of the posts by a claw in the form of a figure eight, the lower part of which opens as the upper- part closes. This claw is acted upon by a lever to which a cord is attached. When the head of the condemned is in position the cord is pulled, and by the action of the lever the knife falls, descending by the grooves of the upright posts and falling upon the neck of the condemned just behind the planks which keep the head in position. The scaffold which is surrounded by an open railing is raised two meters from the ground.
The name guillotine is also given to a type of knife used for cutting paper. Research Guillotine
