Continental Motors Corporation

of Detroit, Michigan, USA
The Continental Motors Corporation of Detroit purchased the Burt-McCollum patents from Wallace (Glasgow)
About the time of the Great Depression, the company developed prototypes of the Single Sleeve-Valve engines for a range of applications, from cars to trains to airplanes; the company thought that production would be easier, and costs would be lower than its counterpart poppet valve engines. Due to the financial problems of Continental, this line of engines never entered production.
