This is a vastly
expanded successor to Dr. Pearson’s earlier Guide to American Brace
Patents 1829–1910. Not only are many newly discovered patents
included, but these are now cross-indexed and illustrated and, for
the first time, the author provides an indication of their rarity.
Over 500 brace patents are listed alphabetically by patentee name
and chronologically by date and patent number. There is a third index
that lists patents by type of brace in four major categories: brace
ratchet patents, corner brace patents, brace wrench patents, and brace
combination tool patents. An invaluable reference for anyone having
an interest in these fascinating examples of American ingenuity.
192 pages.
