Be it known that I, LOUIS VOGEL, a citizen face of the inner strip is fitted flush with the of the United States, residing at \Vhitelaw, under part of the tread 2 of the rail, and the in the county of Manitowoc and State ofWislower projection 10, formed by the undercut 5 consin, have invented new and useful In at the base of the strip, bears upon the supprovements in Paving-Strips, of which the ports for the rail, such as ties or cross-beams following is a specification. or other means that may be employed.

When the strips are used on curves or crossings, additional bolt-holes will have to be formed in the rails at points intermediate the ends of the latter, and in such applications the strips will be given a contour corresponding to the rails. It is also proposed in some instances to use the pavingstrips for reinforcing or strengthening rails on trestle-work, such as bridges, and another material advantage which ensues from the use of the strips is that depressed joints will be obviated in the rail structure in View of the fact that such strips may be extend-ed across said joints and serve to hold the treads positively in flush position relatively to each other. Changes in the proportions and dimensions of the strips may also be resorted to without departing from the spirit of the invention.

Having thus fully described the invention,

what is claimed as new is 1. A paving-strip having a central enlargement, an undercut lower edge, an upper edge shaped to bear against the under side of a rail-tread, and a downwardly and outwardly inclined side, the strip gradually increasing in thickness toward its lower edge.

2. The combination with a track-rail, of paving-strips secured against the opposite sides thereof and closely fitting against the web under the tread and over the base-flange, the outer sides of the strips being inclined downwardly and outwardly to increase the thickness of the strips gradually toward the lower edges thereof.

3. A paviug'strip for a track-rail having an undercut lower edge and gradually increasing in thickness toward said edge.

4. A paving-strip for a track-rail gradually increasing in thickness toward its lower end and having a downwardly and outwardly inclined face.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS VOGEL.
