Downton pump

The Downton pump is type of positive displacement pump patented in 1825 by Jonathan Downton, a British shipwright.[1] It was typically used on ships.[2]

Downton pump operated by sailors

The design of the Downton pump sought to create a more constant flow of pumped liquid, and a steadier load-state on the pump, by increasing the number of buckets operating in the pump. These buckets were actuated by means of a rotating crankshaft and connecting rods, which caused the buckets to reciprocate up and down, with each feeding the next with liquid.[3] Hebert (1836) contains a description and cut-away illustration of an early Downton pump.[4]

Power source

The power source for the pump could be either mechanical or human, with human-powered Downton pumps being operated by means of a capstan.

gollark: Excitingly, the new potatOS thing actually incorporates a lisp interpreter for some reason I forgot.
gollark: Slightly.
gollark: I had to update some URLs.
gollark: Exciting news: PotatOS has been updated. This will be rolling out globally soon. None can escape.
gollark: No activity whatsoever. Is the owner of this even online?
