OSCILLATING CYLINDER LOCOMOTIVE.


This locomotive is the design of Mr. Henry F. Shaw, of Boston.

This engine has oscillating cylinders placed between the driving-wheels.
Fig. 2 represents a section of one of these cylinders, from which it
will be seen that each has two pistons and piston-rods, which are
connected directly to the crank-pins. His invention is described as
follows in his specification:

"Midway between each set of wheels, e and f, is located the oscillating
steam-cylinder, g, having its journals, g' and g", supported in the
stationary arm, h, which is secured in a suitable manner to the frame,
c. To each cylinder, g, is secured or cast in one piece therewith a
balanced vibratory beam or truss, i, as shown. Within the cylinder, g,
are two movable pistons, k and k', Fig. 2, provided with piston-rods, l
