Moreover, in loading long lumber on {iats it will be seen that the section 5 of the staff may be raised from the section 1 and folded upon or adjacent to the platform of a fiat, whereby it may be brought instantly into service after the unloading of the long timber.

It is obvious, of course, that in use upon passenger coaches the section 5 could be formed or made in one piece with the basesection 1, thus making a practically rigid sta.

4. A sectional folding brake-staff, the main section being bifurcated at the top and provided with a pivot-pin, and the upper or handwheel section being iattened to fit the top of the main section and provided with a tapering slot engaging the pivot-pin of said main section.
