Original 1921 electrical trade vintage magazine ad for the ELECTRICAL DEVELOPMENT & MACHINE COMPANY. Main office and plant were located in Philadelphia, PA.

Manufacturers of Franklin Devices.  'You can install the Franklin and forget it'

The longheaded engineer watches out for any little thing that may interrupt the service, and then prevents it. For continuity is vital. A break in service due to a faulty pothead, disconnecting switch or busbar insulator usually means a shutdown. And the shutdown costs far more than the apparatus that caused it. The thing to do, therefore, is to buy the pothead, disconnecting switch or insulator that will not break down. Buy for quality; for safety. 'Install the Franklin and forget it'.

Safety to the plant and employees saves money. Continuity of service means full paying dividends. 'Franklin' equipment guarantees against all trouble at these points. Every 'Franklin' device is safer in a very definite way that you should know.
