Adjustable pier railroad house assembly having dual adjustment capabilities

摘要

An adjustable pier assembly for use with a railroad control house includes a frame member, a movable sleeve having a pair of flanges rigidly attached to an extending sidewardly therefrom, and a pair of fine adjustment threaded members having associated hardware. By adjusting an initial adjustment bolt, an initial "rough" height adjustment is provided between the pier and the sleeve. A final fine adjustment is then provided between the sleeve and the frame of the apparatus by adjusting the location of the fine adjustment nuts which combine to capture the flanges along the lengths of their respective fine adjustment bolts. When four adjustment pier assemblies are used on four corresponding corners of a railway control equipment house, quick initial setup followed by fine leveling adjustment in two axes is readily provided.
