Charles Yale Knight invented the sleeve valve engine, but he never built automobiles. An auto manufacturer who wanted to use the Knight engine had to incorporate the word Knight into the car's name.  Hence Falcon-Knight, Damlier-Knight, Sterns-Knight, Willys-Knight and so on. This picture shows the  combination of sleeves and connecting rods that make up one cylinder for a Knight engine.  Note ports in the sleeves.

View of intake and exhaust sleeve actuating rods and the camshaft, which is actually a miniature crankshaft.
A special jig had to be made to bore these tiny rods.
Note how small the rods really are.
The actuating rods and cam-crankshaft compared to a 7hp Economy connecting rod.
