Upright jerker

The upright jerker was an execution method and device intermittently used in the United States during the 19th and early 20th century. Intended to replace hangings, the upright jerker did not see widespread use.

As in a hanging, a cord would be wrapped around the neck of the condemned. However, rather than dropping down through a trapdoor, the condemned would be violently jerked into the air by means of a system of weights and pulleys. The objective of this execution method was to provide a swift death by breaking the condemned's neck.

Executions of this type took place in several U.S. states, notably Connecticut where amongst others the "Count of Gramercy Park", murderer and gang member Gerald Chapman was put to death by the method. The warden of the Connecticut State Prison at Wethersfield obtained US patent 541409 , issued on June 18, 1895. The upright jerker was never very efficient at breaking the condemned's neck and was withdrawn from use by the 1930s.

A version of the "upright jerker" is used for capital punishment in Iran. Iran uses a crane to jerk the noose upward violently.
