The McIntyre splicing sleeve was invented in the 1880s, but did not become popular with Central Maine Power Co. linemen until the 1920s.
The copper or aluminum sleeves used in the McIntyre splice provided more surface area than other methods, and subsequently more friction, to the splice when it was placed under tension. Wrapping one of the conductor strands at each end of the splice further secured the sleeve.
