Suction cups history and patents.


cupping suction cup

First Documented Usage of the Suction Cup


As far back as third century B.C., the suction cup was more important to the practice of medicine than the stethoscope is today. Suction cups made out of gourds, were attached to the skin and supposedly drew bad blood away from diseased organs to the surface of the body. The procedure, believed to have been invented by Hippocrates the first medical doctor, was called "cupping." It was used to cure a wide range of illnesses. [1]






Suction Cup Patents Date Back to the Mid-1800s


The first modern suction cup patents were issued by the United States Patent and Trademark Office during the 1860s.
TC Roche was awarded U.S. Patent No. 52,748 in 1866 for a "Photographic Developer Dipping Stick." The patent discloses a primitive suction cup meant for handling photographic plates during developing procedures.
In 1868 Orwell Needham patented a more refined suction cup design, U.S. Patent No. 82,629, calling his invention an "Atmospheric Knob." Its purpose was for general usage -as a handle and drawer opening means. [1]

Photographic Developer Dipping Stick Patented February 20, 1866 by T.C. Roche

A new and improved developing stick with a suction pad of India rubber at one end which can raise a glass plate or other material and hold it in the proper position for applying developing solution.

Adams patented suction cup
Suction Cup for Use in Windows, (Light Diffusing Rings) Patented August 13, 1991by William E. Adams (Adams Manufacturing)

Previously existing suction cups tended to focus light like a magnifying glass, resulting in scorched surfaces and colour fading. After years of extensive R&D and testing, Adams Manufacturing invented a groundbreaking new way to overcome this serious product limitation with suction cups using what they called Light Diffusing Rings. This trademarked technology eliminates the hot light focal points that are generated in intense sunlight—often causing damage to plastic, vinyl or textile interiors. To this day, Adams Manufacturing continues to integrate this cutting-edge technology into all of their suction cups. [5].
