Sighn 1: object : chair
The idea of the electrc chair was first thought of by a man called Alfred P. Southwick as an alternative to hanging, he developed the idea of using electric current as a method of execution when he saw an entoxicated man die after touching an exposed terminal on a live generator.
since the first execution of william kemmler in august 1890 the electric chair has become an infamous symbol of the death penalty, it is reported that kemmlers blood vesseles ruptured under his skin and bled and his body caught on fire.
Thomas edison one of the people who helped southwick develop his idea further.
the electrocution of Leon Czolgosz for the assassination of president McKinley, october 29 1901.
First, the system should contain three (3) electrodes. The head should be fitted with a tightly fitting cap containing an electrode with a saline solution moistened sponge. It is through this electrode that the current is introduced. Second, each ankle should be tightly fitted with an electrode, causing the current to divide and guaranteeing passage through the complete trunk of the subjects body. Use of one (1) ankle electrode (instead of two ) will almost always ensure a longer and more difficult electrocution. These two (2) ankle electrodes are the return path of the current. Contact should be enhanced by using saline salve or a sponge moistened with a saline solution at each of the ankle connections. It is of the utmost importance that good circuit continuity, with a minimum amount of resistance, be maintained at the electrode contacts. Further, a minimum of 2000 volts ac must be maintained, after voltage drop, to guarantee permanent disruption of the functioning of the autonomic nervous system. Voltages lower than 2000 volts ac, at saturation, cannot guarantee heart death and are, thus, not adequate for electrocution, in that they may cause unnecessary trauma to the subject prior to death. Failure to adhere to these basic requirements could result in pain to the subject and failure to achieve heart death, leaving a brain dead subject in the chair.

The Electric Chair
The electric chair consists of an oaken chair with an adjustable backrest, inherent leg electrodes, a leather and sponge helmet with electrode, a drip pan, a plexiglass seat and a non-incremental restraint system. It is covered with a high gloss epoxy paint similar to that which is used in the space program. It is connected to the power supply via one military type connector. This chair was fabricated in part with wood from Tennessee's original electric chair.
The ankle electrodes, which are fabricated onto the leg stock, are turned of solid brass. They accommodate a #6 conductor and are paralleled to ground.
The helmet consists of an outer helmet of leather and an inner helmet of copper mesh and sponge. It will disassemble for repair and the electrode will accommodate a #6 conductor.
The chair design includes a removable drip pan. The straps are of nylon aircraft construction and consist of two (2) ankle straps, two (2) wrist straps and one (1) cross-the- chest harness, all with quick release fasteners. All fasteners comprising the restraints are non-incremental, enabling a tighter fit.
The entire system, because of its modular design, may be installed by non-technical people in several hours and is fully field repairable
