The 1915 Directory of Directors of the City of New York shows a Mr. Edwin Baltzley as President and Director, and a Mr. Louis Baltzley as Treasurer and Director of the L.E.B. Co., located at 115 Broadway, New York, NY (which according to the later Facebook post was relocated at some point.)(?)
The author of the Facebook post says the 47-piece "Multi-tool" was being sold from about 1912-1915.
I haven't found a patent number for the L.E.B. "Multi-tool" as of yet.
It's worth noting that Mssrs. Baltzley were each issued a number of patents, each under their own name, for a number of devices, among them egg-beaters, a sound-deadening device for typewriters, a "culinary beater", and a coin sorter, among others. The most lucrative, no doubt, being the patent issued to Louis (the son of Edwin) for his paper binding clip.
