I did some restoration work on an antique pump that I showed in an earlier post. As mentioned, I think it could be a bilge pump for a small craft, activated by wave action rocking the boat to make the weighted pendulum operate the diaphragm pump. In addition to the “Columbian” logo plate, it’s stamped with “PAT. APP. FOR” on one of the bronze castings. I did a bit of searching but haven’t yet found a patent for it, and I’m wondering if it was ever patented.
I took it apart, cleaned it, chemically restored the patina, and mounted it on a piece of oak. After cleaning the ball-check valves, I found that it still pumps water, although the rubber pump diaphragm has stiffened up over the years and needs to be replaced. As far as I can tell, the pump is all original. I still haven't been able to find another one like it. If anyone has more information about it, let me know.
