Back when I was young, people wore re-usable clothing. Because of the accumulation of environmental contaminants, a combination of solvents and surfactants was employed to transfer the contaminants from the clothing, back into the environment. A method was devised to utilize solar irradiation to increase the vapor pressure of the residual solvent, allowing it to disperse into the air we breath. In order to optimize this latter process, the treated clothing was suspended outdoors, and prevented from blowing away, by the use of a galvanized steel spring leveraged with two entrapped, slightly angled, wooden splints. This combination of spring and splints was generally known as a "clothespin," even though its design could be applied to holding other items in a fixed configuration: opened bag of frozen lima beans, breached potato chip bag, partially used poly-nylon bag of WLT tobacco leaf, binder of a bunched cigar, etc.
The coil of the spring functions as the lever fulcrum for each
wooden splint, while its two 90º appendages serve to apply
force to the splints, drawing them together. Two parallel
grooves at the narrow end of each splint provide improved
traction, minimizing the risk of fingertip displacement during
the application of compressive force on the assembled
device.

Springfield, Vermont, in 1853.)
