A Brass-Handled Concrete Finishing Trowel

Concrete, Vol. 9, No. 2, Feb. 1909

Hayden Automatic Block Co. made a concrete finishing trowel with a removable brass or aluminum handle. This is the only finishing trowel I have seen with a brass handle. The aluminum option was dropped 1909-1910.

Hayden Automatic Block Machine Co., 112 West Broad St., Columbus, OH, also made concrete block machines and concrete mixers. The company was named for William B. Hayden (1839-1916), an inventor and manufacturer. In 1924 the Kent Machine Co. of Kent, OH, purchased the right, title, and interest in all patents, patterns, machinery, tools, and equipment of the Hayden Automatic Block Machine Co. 

Concrete, Vol. 10, No. 3, Mar. 1910, page 122
