I’d have to say the vault door I found must be a Farrel, it’s quite similar to the safe image you found. I assume that the right-hand wheel says “FARRELS PATENT”, there is just a bit of “T” in the image.
But I did not find a patent. However, I did find a patent for John Farrell, assigned to A. Farrell of Philadelphia, for a steering-wheel lock (US patent 1,470,823). Note the spelling difference. The company was part of the merger that led to Herring-Hall-Marvin.
The safe is interesting because it has a sort of compound hinge that allows the door to be closed in a direction parallel to the opening, much like a crane hinge and pressure system on large vault doors. Notice the handle on the top hinge. See US patent 153,348.
Thanks again for sharing your discovery.
