✅ SOLVED PLEASE help with Patent # I.D. on Cuff-Links...

[tokenhead]

Hello EVERYBODY!!!,
I got these cufflink's some time ago and was looking for a makers mark to get an idea on age.
I have searched U.S.Patent #'s with NO luck...Maybe they are NOT American made!??! Anyway's i found PAT 19507 on the inside,I have posted pics but could not get a really clear pic but it read's as said PAT 19507 and when i search that some contraption came up.I was close at one point but was not able to figure "Advanced" search out so ANY help,Point in right direction,Etc. Will be greatly appreciated!!!
These are NOT "fine" jewlery as the blue end-caps are plastic...I'm thinking 1940's-50's...
P.S. After seeing pics they are no good!!! Can not see marking,But it is known what it is-PAT 19507
