The key to their short and long-handled cement tools was a handle attached with a simple swivel joint. The cast iron handle has stepped recess, and a large brass nut is machined to fit into it. The result is a joint that allows the handle to be secure while allowing movement, is easily removed, and is easily cleaned. Here are 2 articles about Arrowsmith's products in Municipal Journal & Engineer, 1910.
Arrowsmith Concrete Tool Co. was represented at the 1911 Chicago Cement Show by W.A. Scott, J.H. Jacobs, George M. Slingloff (1879-1949), and Ralph L. Sohn. The 2 patents for their tools were by Mr. Sohn (10 Jan. 1879 - 19 Oct. 1956). Mr. Sohn was a blacksmith in Arrowsmith and nearby Cheney's Grove, but his position with the tool company is unknown. He assigned his 1911 patent to Henry M. Scott and Ralph A. Scott, so it's possible that they were the company owners, but I have been unable to verify that.
