Patents

I would like to reproduce some of the Stanley mechanisms such as the water regulator, special valves, etc. Does anyone know what the patent numbers for any of these things are? Closest I have come to the Boiler Water Regulator is US1777645A, but the diagram isn't like the picture in the Stanley articles. Any ideas would be welcome. Thanks.

The finished product is rarely like the patent drawing.
The best way in my opinion is to borrow one with the understanding you intend to take it all apart and do drawings of each part. I have done this on many parts.
