ance of spring-l6 the rod 42 is actuated downwardly so as to close' the transverse bore 3? and to bring the opening 41- into alinement with" the bore 38. Pressure will be admitted through bore 38, tubular portion 43, bore 37. and tube 23 to the cylinder 7 to more piston 8 and lift the latch. The lever 33 is then swung to one side or the other, as it may be desired to more the reverse lever 1. so that pressure is directed,

into one or the other tubes-2i or 25 through ducts 40 and into one end of cylinder 16 to more piston 17, while the other end of the cylinder is drained through the other tube and duct ll. Then by releasing lever 45 the rod 42 resumes its original position so as to release the pressure intcylindor T and the spring-latclri' rvseats itself, the cylinder draining through exposed bore 38;

Having thus described my invention, what I claim is 1. A valve for controlling motors co1nprising a casing. inlet and exhaust ports in the sides of said casing and on difi'erent planes, tubes tapped into the sides ot'said casing, a tube tapped into the end of the I g, a piston revolublv mounted in the ca 1g, the piston formed with a longitudinal central bore and lateral bores on the same planes as the inlet and exhaust ports,
