Peake Engines No.2 stationary steam engine

Serial No 8

Peake No.2 is a limited edition of engines of distinctive design, this being serial number 8. It follows on from the No,1 and, likewise, the main engine frame is an ornate casting. Unlike the No.1, the base is also a heavy casting, hexagonal in shape. It is large compared with most of Ben's creations.

The single acting fixed cylinder is 1/2" diameter and 5/8" stroke. It is mounted vertically on the base. Like the No.1, the small end of the connecting rod is inside the piston, as is common practice in internal combustion engines but unusual in steam engines. This enables the con rod to be a single piece without the need for a cross head. It has a simple cylindrical valve mounted remote from the cylinder, on the other side of the frame. It is controlled by a fixed eccentric on the crankshaft. The main bearing is fitted with an oil cup with an ornate cap. The flywheel is a heavy machined casting 3 1/2" diameter, with ornate S shaped spokes. A small pulley is mounted adjacently on the crankshaft.

The instructions supplied with the engine state that the main bearing should be libricated with thick steam oil and the piston with thiner SAE30. This is the converse of usual steam practice and I'm not sure if it is a misprint.
