An adjustable pin is fixed vertically above the axles and to the frame on each side of the boiler, and extends downward and through a vibrating bar, terminating on the upper surface of the multileaf spring. The fore and aft ends of the spring are connected to the boxes in which the wheel axles revolve. The boxes are made so that they swivel in the plumber blocks which receive them, by boring cylindrical recesses in the blocks. These blocks are secured to the vibrating bar so that the parallelism of the axles is undis- turbed. Cat. No. 251,274 Model of Locomotive Invented by G. H. NicoUs, 1848. TJ. S. Patent No. 5532.
