Connecticut Telephone and Electric Co telephone


Above, design for a telephone (for a small apartment or office building presumably) by Joseph O. Cadieux for Connecticut Telephone and Electric Co. (letters patent no. 1,181,947; 2 May 1916). For more information, see the listing below.


"This fast growing manufacturing concern... is the result of the small start made by E. C. Wilcox in 1893. In 1894, B. L. Lawton entered into partnership with Mr. Wilcox... In 1902 the business of the firm had so increased that they were warranted in purchasing the present factory... and on March 1, 1903, were incorporated with a capital stock of $36,000, but which, by another act of the legislature, has since been inceased to $45,000... The high quality of their product, which comprises telephones, telephone switch-boards, and electrical supplies, has placed them in the position of the largest manufacturers of their goods in this section of the country... They make everything in their line from the raw material to the finished product... " [Excerpt from A century of Meriden (1906). See entry below.]

The new phone is designed to eliminate the common annoyance and embarrassment which is frequently caused to apartment dwellers when callers ’miss’ the door-opening signal.

"... Connecticut Telephone & Electric Company of Meriden exhibited its new private line radio telephone system equipment at the Eastern States Exposition. Called the Fleetway and is a two-way mobile radio, operated on UHF. The FCC recently allocated a large portion of the UHF frequencies for public use, making it possible for any citizen over 18 years old to obtain a license for the operation of mobile radio equipment.

Among those who can now obtain licenses in the new band are doctors, salesmen, newspaper reporters and photographers, appliance service men, delivery fleets, factories, construction companies, and many others.

Contelco’s new Fleetway is built on an exclusive, patented circuit design called the "Lister" circuit. The new circuit makes possible, for the first time in mobile radio, true frequency modulation. The number of components needed are also substantially reduced, resulting in less maintenance and lower up-keep costs." (Excerpt from above.)
