Tompson Lock - Patent 1808
I would be very interested in any articles, information or details of any books which would cover the subject of Tompson Locks. All I know is that they were more complicated than a Bramah at the time, in that they went up and then across 'on the horizon' to lock. His name was William Tompson and he applied for a Patent - No. 3188 - in 1808.
Thank you.
