For some time the demand for these cas s has been such thattheir manufacturer, the Lyon Metallic Manufacturing been unable to supply the demand of its sales agent, the Elec-tric Service Supplies Company. Recently the manufacturing com-panys plant has been quadrupled in size and it is now stated thatorders for gear cases can be promptly filled. These sheet-steel gear cases have made such a successful rec-.

The Albert & J. M. Anderson Manufacturing Company, Boston,Mass., has perfected a mechanical time switch that embodiesmany points of superior merit.
