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.
