SPEEDING EXPERT McCALEB BUILDS NEW BURGLAR ALARM

NO WRITER ATTRIBUTED

Thomas S. McCaleb, instructor 19 Geographical exploration and formerly of trafile control fame, has switched his field this time to catch bookthieves instead of speeders.

His latest invention is an antenna arranged behind a stack of books in a shelf in such a way that electrical waves in a perfect state of balance, flow between the antenna and the bookcase.

When a person comes within two feet of any of the books the state of equilibrium is disturbed and a high frequency current is set up. This current produces a light signal which can be located in a janitor's office or in any other suitable room.

McCaleb sees possibilities for his new burglar alarm as a fool-roof device to protect safes and vaults but he has not yet experimented fully on the subject.
