John Adt & Son, Builders of Hardware Manufacturing Machinery , corner State and Mill River Streets, New Haven.—Connecticut is famous not only for the variety and volume of its manufactured articles, but also for producing the machinery for making the output of her numerous mills and factor1es—not only “making the things, but making the things that make them." The house of John Adt & Son is one of the principal enterprises of New Haven, devoted to the production of machinery for manufacturers’ uses. The industry was inaugurated by the senior member of the firm in 1869, and he in 1883 admitted his son, Mr. G. W. Adt, to an interest in the extensive business he had founded and developed.

      The machine works of Messrs. Adt & Son are located at corner of State and Mill River Streets, and comprise large building 40x100 feet in dimensions, and two stories in height. The plant is a valuable one, including fine improved machinery of latest designs and patterns operated by steam, and twenty five skilled workmen find constant employment in the establishment.

      The output comprises all kinds of machinery to order, a specialty being made of that used in wire working, hardware manufacturing, of which the firm turns out large quantities and in great variety. The firm’s facilities for supplying work of the most accurate and reliable character are unsurpassed, and designs and estimates are furnished, and orders promptly executed, satisfaction in every regard being uniformly guaranteed.

      Mr. John Adt is a German by birth, having been born at Ensheim, in Rhenish Bavaria, and is a veteran mechanical expert. His son was born at Waterbury, Conn., and has had large experience as a practical builder of machinery.

      Both are enterprising, reliable, progressive men of business and have well earned the gratifying success they have attained.
