IMPROVEMENT IN RAILROAD-RAILS.

Like letters of reference indicate corresponding parts The advantages oi' this arrangement over those at in all the figures. rst mentioned are obvious.
Many attempts have been made to construct a rail l When the tread is welded to the base, the whole with au inferior base, and superior cap or tread, which railmust be thrown away when the thread is torn can be replaced when worn out, without discarding the out. And when the cap is combined with the hase base. loosely by sliding on, the rail is practically useless, One plan has been to use a steelface, welded to an owing to the irregular play of the tread and frequent iron base or body, and rolled with it. The great obbreakage and disarrangement, as has been abundantly jection to this, is that when the superior fsm is worn proved in practice. out, the whole rail must be discarded as useless, as By employing a separate and independent cap, the steel and iron caunotbe separated. rolled closely to the base, so as to adhere thereto, Another plan has been to employ aloose face or cap, form a. unit of the rail, and avoid all these diicnlsliding eudwise on the base, and secured by bolts so ties. as to be removable. The dimculty in this case is that Besides the above advantages, there are others, :is the parts are loose and rattling, are eas' y broken, and follows: do not form, as it were, an integral whole. If either the base or cap should break, and the My invention consists in combining the cap with other part remain entire, the rail would remain intact, the base, by rolling the two partitcgether, alter being by reason of the closeness and tenacity with which separately formed, so as to have a natural adhesion, they hold together; and as they are distinct and inwhich holds as firmly in place, under action, as the dependent parts, it is not probable they would break natural rail, but is still easily torn apart and replaced in the same place. when worn, whereby the same base is made available If a rail with a welded cap or face were to break, it
