label: Description
content: The model represents a vertical steam engine with an oscillating cylinder, circular slide valve, and hollow cylinder trunnions for the admission and exhaust of steam. Steam is admitted to the center of the annular valve through the adjacent trunnion. The exhaust is conveyed from the valve seat around the cylinder in a hollow band cast on the cylinder for that purpose and leaves the engine through the opposite trunnion. The valve is driven by an eccentric on the shaft. The valve rod is provided with a cross head moving in a guide on the cylinder and oscillating with it. The eccentric rod carries a pin that slides in a curved slot in the cross head and produces an even motion of the valve thereby.
