Jones plugs, or similar sorts of plugs

Clark Quackenbush for use in the radio industry..." I wonder about this, however. Quackenbush's name appears on US patent 2,422,982 (1947), but it deals with T- and L- UHF adapters. And his full name (on the patent) is "Edward Clarke Quackenbush"--not "Clark" as Amphenol would have it. However, the connector *was* pre-war. See patent 2,335,041, Bruno, 1942 "Right Angle Electric Connector". That is *definitely* a 239- type connector shown in the drawings, but no patent references are given. Does anyone have a very old SO/PL 239 with a patent number on it? As an aside, patent 477,951, Menger, 1892 shows what amounts ot a coaxial cable, but its purpose was for electrical distribution and no mention is made of RF applications (understandably). Frustrating--I know the patent for the thing has to be out there, but finding it isn't going to be easy. Maybe I should join the fray and offer my opinions of Microsoft products...it requires less thought and goes better with beer... --Chuck
