Doorway

The way into the engine house is up a flight of steps to the first floor level. When you enter the engine house the centre of this level is taken up by the main cylinder and the controls for the engine (picture will follow). Go up a level and this is the cylinder head floor, head up one final set of stairs to the "bob" floor. The "bob" is the name the Cornish give to the beam (cos it bobs up and down) half of the beam is inside connected to the piston rod and parallel motion linkage and while the centre of the beam pivots on the "bob" wall of the engine house. The other half of the beam is outside connected to the pump rods or the winder depending on what type of engine it is.
