| Post subject: | Patent Plates On Boilers |
I had a good look recently at an ALCO boiler plate that measured about 4" X 4 1/2" with a bunch of patents listed and their issue dates. What was the purpose of this plate? It seems to me that the patents were random and am not sure why ALCO would go to such an extreme to rivet a plate like this on a locomotive smoke box under the builders plate. Were the patents that important? Brian Hebert |

These are the titles to the respective numbers. Couple of these don't seem to make a lot of sense (and dates are wrong) 744400 (11/17/03) Locomotive Frame 773713 (11/1/04) Locomotive Engine 823482 (6/12/08) Locomotive Truck 838418 (10/12/09) Valve Mechanism for Turbines 833840 (5/2/11) "Type Writing Machine" - issued Oct. 23, 1906 882631 (5/10/11) "Fly Trap" Issued - March 24, 1908 1135732 (7/6/18) "Can Strengthening Means" issued April 13, 1915 Could you recheck the numbers on the plate for the last 3???? These are easily downloadable in *.pdf form by entering the numbers at http://patft.uspto.gov/netahtml/PTO/srchnum.htm (or Google patents should have these too) At least the first 4 sound relevant?
