Leslie Brothers contracted with Cooke Locomotive & Machine Works in Paterson to do the actual construction.
Jull later sold his design rights to Leslie Brothers, who formed the Rotary Steam Shovel Manufacturing Company in Paterson, New Jersey. During the winter of 1883–84, Jull contracted with the Leslie Brothers of Toronto to build a full-size prototype that proved successful. Orange Jull of Orangeville, Ontario, expanded on Elliot's design, building working models he tested with sand. He never built a working model or prototype.
The rotary was invented in Toronto, Canada, by dentist J.W. A rotary snowplow from the Oregon Short Line on display at the Mid Continent Railway Museum in North Freedom, WI.
