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, illustrated and 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
