Unknown Engine…

Hi there

New to the forum and recently picked up an engine which I had hoped may be able to run a smaller launch 15’ or so.

It has two 2” cylinders with a stroke about 1.5-1.75”. The head appears to maybe be bronze? With brass pistons?

It’s about 15” tall x 10” wide and 7 deep.

It’s missing a few parts (mostly bolts), and the piping.

My plan is to restore it, polish and clean it up and tidy up any areas that need attention.

Any thoughts on a make/designer would be appreciated. It has a cross head piston attachment for a water pump by the looks of it.


Cheers
Markus

Hi Markus,

a very interesting engine.

You can built a pump unit with a condensate pump in the middle and a boiler feed pump a the right an a circulating pump at the left side. Or you split it to every crosshead.

I have calculated the dimensions of the boiler feed pump as follows:
Bore 8 mm
Stroke 44 mm

The length of the boat should be a bit longer 17 - 20'.

Best Wishes
Dietrich
