One of the notable industrial enterprises of Detroit which have given the city a place among the leading manufacturing centers of the world is that conducted by the corporation whose title initiates this paragraph. The company are the largest manufacturers of coin slot apparatus in the world, and the Detroit plant of the concern, at 1300-1340 Second avenue, is likewise the largest of all factories devoted to this line of manufacture. The gigantic enterprise is further conspicuous from the fact that it represents the concrete results of the technical skill, progressive ideas and energy of business men of the younger generation, —men whose fine initiative talent has enabled them to build up a magnificent industry within the space of comparatively few years. The enormous sales of the coin slot machines of the Caille Brothers Company testify lo the distinctive merits of the products and to the popular appreciation of the manifold devices of this line sent out by the concern into all sections of the civilized world.

The Caille Brothers Company was incorporated under the laws of the state of Michigan in 1901, and its operations are based on a capital stock of three hundred thousand dollars. Coin-controlling machines of fully eighty different types are manufactured and each is of the best mechanical construction, backed by the positive guaranty of the company. The annual output of the plant has now reached the enormous average of fully twelve thousand machines, all of which are protected by patents issued to the Caille brothers, who are the inventors of the various mechanical devices employed. The business had its inception in 1893, when the Caille Company was organized and began operations on a modest scale in the city of Saginaw, Michigan, where the headquarters were maintained until 1896, when A. Arthur Caille and Adolph A. Caille, the two interested principals, came to Detroit and here laid the foundation for the present enterprise controlled by their company. Both brothers are practical mechanics and specially skilled as artisans, and both have shown distinctive ability in the invention of mechanical devices. The original factory in Detroit was one of modest order and was located at the corner of Woodward and Baltimore avenues, from which location the removal was made to the corner of Second and Amsterdam avenues in 1904. At the latter and eligible location was created the fine, modern plant utilized by the company at the present time. The large buildings are substantially constructed of brick and stone, and the main building, one hundred and twenty by three hundred and fifty feet in dimensions, is three stories in height, not including the basement. The factory proper lies at the rear of the main building and is one story in height. In the prosecution of the various details of manufacture employment is given to an average force of three hundred persons, of whom fully seventy-five per cent, are skilled mechanics, and the average annual expenditure in wages and salaries aggregates two hundred and twenty-five thousand dollars. In capacity, output and extent of business controlled, the concern outranks all others of the kind in the world, and its value to Detroit is large, both in a direct and collateral way. It is not within the province of this article to enter into details concerning the products of this great industrial institution, but the literature issued by the company gives all information that can be asked in this regard. Agencies are maintained by the company in the leading cities of the United States, as well as in those of European countries and other foreign lands. The stock of the company is virtually controlled by the Caille brothers, of whom A. Arthur Caille is president and general manager, and Adolph A., vice-president and secretary. The former has the general supervision of the finance and sales departments of the business, and the latter has charge of the manufacturing and the directing of the general accounting and office affairs. Personal mention of the brothers is made on other pages of this volume.
