Scholler Manufacturing Co., Inc. (Buffalo, NY) - Incorporated June 6, 1917 by Charles J., Edward J. and Caroline Scholler. However, in 1914 the company was sued by Crescent Tool Company for patent infringement for "sector cutting saws." Here is a 1915 advertisement for the Scholler adjustable wrench, from the Cycle & Automobile Trade Journal. A google search produces images of "double end" adustables also marked with the Scholler name.
Charles J. Scholler may have come from Keystone Manufacturing Co. as his 1912 patent for a ratchet drill was assigned to Keystone.
