Context

Country: Unknown
State/Province: Unknown
Period: This device used c. 1940- 1945.
Canada: Part of a large collection of medical artifacts, archival material & trade literature transferred to CSTM in 2002 from the former History of Medicine Museum, Toronto, ON. Designed and made by Dr. D. Revell of army telephone wire and 5,700 Ohm resistors. Used in 3 Canadian field operating rooms in WWII which had canvas floors which were statigenic. [Refs. 4 & 6]
Function: To equalize the electrical potential of all connected objects without producing sparks.
Technical: Designed and made by Dr. D. Revell of army telephone wire and 5,700 Ohm resistors. Horton's intercoupler, after which this device was modelled, was introduced into the U.S.A. in the late 1930's. It's main feature is the high resistances in leads between people and objects in the O.R. which allow the rapid disappearance of frictional charges. The disadvantage is the wires dangling in the O.R. going from the patient, surgeon, anaesthetist and anaesthetic trolley. [Ref. 4]
Area Notes: Unknown

Finish: Red and black synthetic covering over metal wire; black synthetic radio tube base has tar plug: silver metal chain attached to both sides of one edge of tube; brass (?) band links covered wires together; copper (?) ground wire.
