Early 20th century fraternal lodge initiation electric shock device used for hazing rituals, which were mild by today’s standards. This beastly device was probably constructed of canvas, filled with excelsior, and wired for mild electric shock. It was fitted with harnesses for four men to ride. The beast was controlled by the man in front. Whenever he wanted to turn on the “juice” he did so, to the surprise and displeasure of the the riders. The members of the lodge who were looking on knew all too well what kind pain they were feeling and where they were feeling it!
