This form of engine is essentially the Charter already described, but made by the H. W. Caldwell Son & Co., of 129 West Washington street, Chicago. The Mr. Charter of the Caldwell-Charter Co. is a son of Mr. John Charter, the designer of the original (Sterling) Charter engine. Hence the similarity of both form and detail that may be noted by a comparison of the cuts. The Caldwell-Charter has the same general make-up, the same cog-driven poppet valves, tube ignition, governing by omission of charges, and Otto cycle as the Charter engine proper, and like it is largely used on gasoline.
In sizes, however, it is made somewhat larger, or up to 65 Act. H. P. Redesigned by Mr. J. A. Charter, in 1891, it was put on the market in '92, and over 100 engines, aggregating 800 or 900 H. P., are already in use.
Cassier.s Magazine for April, '93, gives a detailed description of this make of the Charter engine. There is no connection whatever between the Sterling makers and the Chicago concern. |
