A PDF of US patent 3,263,485 is available here: http://www.pat2pdf.org/patents/pat3263485.pdf . The Google Patents version is not that great.

The application number or serial number (Ser. No.) is 341,349 as shown on the second page of the patent publication.

The patent has 6 claims - 3 independent claims and 3 dependent claims.

It was filed January 30, 1964, issued August 2, 1966, and is now expired.


The application no. is: US19640341349 19640130 There are 6 claims.

  • This answer would be better if it described the method used to obtain the application number.
