Go another 15 minutes west of Lou in Syracuse to Jordan where I live. I have never heard of a lock company in the Central New York area, although I have seen many American padlocks.
Wikipedia mentions: "The earliest record of the wafer tumbler lock in the United States is the patent in 1868 by Philo Felter. Manufactured in Cazenovia, New York, it used a flat double-bitted key."
From this rootsweb page;
http://www.rootsweb.ancestry.com/~nymadiso/1899-14.htmThe American Lock Manufacturing Company, incorporated in 1875, with a capital of $25,000, purchased the business in that year of the American Lock Company, which had for several years manufactured a lock of new design in a machine shop near the Albany street bridge. In the same year a building occupied by Stephen Chaphe as a machine shop was purchased by the new company and fitted up for their business. In April, 1878, the business was sold to the Yale Lock Company and removed to Stamford, Conn.
