In laying our improved railway the chairs or cradles 0 rest in ballast only, and no sleeper or tie is necessary. In order, however, to secure more perfect and continued alignment, we prefer to rest the cradles or chairs 0 on blocks of metal or stone D, conforming to the external shape of the said cradle 0, (see Fig. 3;) or the chair 0 may be given an external shape similar to and in lieu of separate blocks D.

Te desire it to be understood that we do not confine our invention to a combined rail and stringer in which the upper surface or tread of the rail proper is of the specific conformation shown in the drawings, as the latter may be varied and any well-known form of street-rail-tread adopted in place of that shown, the essence of this part of our inven-- tionbeing the combination of such a rail with a stringer, consisting of inwardly-inclined concavo-convex sides made integral therewith and meeting at the base.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A combined street railway rail and stringer consisting of the rail proper or tread A, with longitudinal sides B B, formed integral therewith and of concavo-convex form, inclining" inwardly toward each other and meeting at the base, substantially as described.

2. A combined street railway rail and stringer consisting of the rail proper or tread A, with longitudinal sides B 13, formedintegral therewith and of concave-convex form, inclined inwardly toward each other and meeting at the base, in combination with a chair or cradle O, conforming on its interior to the external shape of the stringer, substantially as described.

8. A combined railway rail and stringer consisting of the rail proper with longitudinal sides formed integral therewith and inclined inwardly toward each other and meeting at the base, in combination with a chair or cradle conforming on its interior to the external shape of the stringer, and with tie-rods E E passing through the same and connecting the two sets of rail stringers and chairs forming the tramway, substantially as described.

In testimony whereof we have hereunto affixed our signatures this 28th day of March, A. D. 1891.
