Description:
Pliers formed from folded sheet metal with double thickness in the handles and jaws, single thickness at the pivot point, and central spacer disk.

The company's No.17 (Pat. Apl'd For) and No. 170 "gas burner pliers" used this patent.

Fence pliers incorporating a hammer poll and wire cutter on the portion shown as a central disk -- produced by the Bridgeport Manufacturing Company -- marked with this patent date -- match this patent's provisions and drawings. Three variants are shown as numbers 63, 64 and 65 in the "Collectors Guide For Fencing Tools" by Richard Smith and Richard Smith, Jr.

Two of the patentees are also listed as inventors of patent no. 672,654 - another sheet metal pliers.
