As I understand this so far, the Bohn patent covered a hatch cover that allowed the hatch plug to be left open while still baring access to the ice bunker, while the Moore device is a permanently installed heater.
The important Bohn patent, created by John Ames (No. 625309) and sold to Bohn, was a "syphon" system of curved metal strips in the bulkhead between the ice tanks and the car interior, supposedly to assist air convection. There were also Bohn-patent details in the collapsible bulkheads used in some cars. The hatch cover, to me, is NOT the important Bohn device. I discussed this, and provided literature citations, in the PFE book.
