dep5 Posted December 16, 2012 Share Posted December 16, 2012 I have a pair of wiper motors with heart shaped covers and the newest patent # on them is 1849327. This Utility Patent was issued Mar 1932 so this means (for the wipersI have) assuming a conservative 9 month manufacturing lead time for engraving the new patent in tooling and the prototype and sample casting approval cycle followed by production, assembly and delivery, etc. I feel it is very unlikely that any heart wiper with this patent could have been shipped on a car built prior to Jan 1933Patent US1849327 - OP BUFFALO - Google Patents[TABLE]<thead>[TR][TH]IssueYear [/TH] [TH]FirstUtility [/TH] [TH]FirstDesign [/TH] [TH]FirstPlant [/TH] [TH]FirstReissue [/TH] [TH]FirstStatutoryInventionRegistration[/TH][/TR]</thead>[/TABLE][TABLE]<tbody>[TR][TD]1929[/TD][TD=align: right] 1696897[/TD][TD]D077347 [/TD][TD] [/TD][TD] RE17176 [/TD][TD] [/TD][/TR] [TR][TD] 1930[/TD][TD=align: right] 1742181[/TD][TD]D080254 [/TD][TD] [/TD][TD] RE17550 [/TD][TD] [/TD][/TR] [TR][TD] 1931[/TD][TD=align: right] 1787424[/TD][TD]D082966 [/TD][TD] PP00001 [/TD][TD] RE17917 [/TD][TD] [/TD][/TR] [TR][TD] 1932[/TD][TD=align: right] 1839190[/TD][TD]D085903 [/TD][TD] PP00006 [/TD][TD] RE18312 [/TD][TD] [/TD][/TR] [TR][TD] 1933[/TD][TD=align: right] 1892663[/TD][TD]D088847 [/TD][TD] PP00052 [/TD][TD] RE18705 [/TD][TD] [/TD][/TR] [TR][TD] 1934[/TD][TD=align: right] 1941449[/TD][TD]D091258 [/TD][TD] PP00085 [/TD][TD] RE19038 [/TD][TD] [/TD][/TR] [TR][TD] 1935[/TD][TD=align: right] 1985878[/TD][TD]D094179 [/TD][TD] PP00117 [/TD][TD] RE19409 [/TD][TD] [/TD][/TR]</tbody>[/TABLE]Do any of you have a 'heart' wiper with a patent number newer than 1849327 ?
