William Wheatstone 1861 patent


Recommended Posts

Only just noticed mixture of brass and steel reed shoes. How are the reeds attached on the steel shoes?


I keep looking at these photos of the steel reed shoes and wondering how they did it. It looks like welding, but I don’t think they could do that in the 1860s? (at least not gas welding) However, if it was some sort of brazing, or solder, you’d surely see the difference in metal colour, and forge welding would surely have destroyed the slot? Better close-up photos might help as these are a bit blurred when you try to enlarge them.
