pearn engines
« on: 07 August, 2015, 08:01:04 pm »
These two engines form part of our steam collection. They were made by Frank Pearn and distributed by Smellie and Co. according to the brass plate.
What application would they have? I'm thinking maybe they would be steam pumps?? I am writing a descriptive label for them - any help appreciated.
Tried to post pics with no success.

Am I right when I say that in Tasmania ,somewhere there is I am sure " Pearns Steam World'' ,a museum . Some of our Tassie members would know . I know someone here in WA that a very large Pearns triple throw water pump and I think there may be a Pearns steam pump here in my town ......I amsure I have a  photo of it ................I'll try and find it.

Hi...... most likely use as boiler feed water pump , had a similar Vauxhall pump on my traction engine years ago.

Thanks Martyn. Could you explain (in layman's terms) how it was used? Did it feed water to the boiler of a large portable Ruston Proctor or similar? If so, from where did it derive its power? Was it actually attached to the larger engine?

These pumps were more commonly used to feed water to fixed boiler installations. The pump would be wall mounted with the fly wheel at the bottom. They are powered by steam from the boiler which is feed to the steam cylinder at the top of the pump. A rod from the piston in the steam cylinder runs down to the piston in the water cylinder at the lower end of the pump. Another rod runs to the flywheel forcing it to rotate as the piston rod descends and rises. An eccentric on the flywheel shaft operates the valve to the steam cylinder which slides up and down allowing steam to flow to one side of the steam piston then the other maintaining the reciprocating action.
Hope that makes sense of it!
there is a picture of a nicely restored one here http://prestonservices.co.uk/item/f-pearn-vertical-banjo-type-rotative-boiler-feed-pump/

I could have told you all that mate! I'm doing one up as we speak, I just washed the oil off my hands after fitting some gland packing.

Hello F Pearn and Co were a very big engineering Co in Manchester in the NW of the UK - and specialised in many types of engines and pumps (steam) over 100 years ago - and they exported, as did many British engineering companies during this time worldwide TK

There is a lot of background information here:
