Lindsay's Cutting Nipper (1883 write-up) - (FLICKR)
|
|
Description: |
| The key feature of the patent is the "elbowed lever" handles which provide compound leverage to to working jaws. The cutter jaw form includes a "stop" to prevent the jaws from cutting into each other.
Corresponding British patent GB-187304113 was registered Dec. 13, 1873.
Lindsay's subsequent patent 147,850 modified the design to have one side placed against a flat surface. [Neither patent includes a "return spring" to open the jaws.]
An 1883 American Machinist "new product write-up" shows a form with a "return spring," and names a Chicago firm as maker. "LINDSEY'S (sic) NIPPERS" appear in early 1890s hardware catalogs, and at least one form was made by Peck, Stow & Wilcox Co. in the late 1890s. A pliers marked LINDSAY'S PAT'D with this date and April 24, 1883 (i.e. patent no. 276,417) is known, but the manufacturer has not been identified. The form of "return spring" appearing in these nippers and pliers may be a clue to their manufacturer(s).
