SPECIFICATION forming part of Letters Patent No. 767,145, dated. August 9, 1904,

Application filed [.prl'. 27, 1904. Serial No. 205,195. (No model.)

T 0.7 lull/071a it may concern..-

Be it known that I, Join A. GUILER, a citizen of the United States, 1' siding at Connellsville, in the county of F 'ette and State of Pennsylvania, have inveij ed new and useful Improvements in Railroz i-Tics, of which the following is a specification.

My invention relates to improvements in metallic railroad-ties, the object thereof being to provide a hollow metallic tie provided with fastening means, whereby the rails may be securely fastened thereto, as well as providing the interior of said shell with an elastic memher composed of compressed cork to furnish acushioning means for a purpose hereinafterthe elastic member adapted to slidingly fit within the shell shown by Fig. 3. Fig. 5 is a detail showing the wedge member for clamping the rail-section to the tie.

Like numerals indicate like parts in the several figures.

6 designates a tubular metallic cross-tie rec tangular in cross-section and provided on its upper surface adjacent to its ends with railbearing recesses or sockets 7, arranged transversely thereof and in spaced parallelism. The walls 8 of these recesses are undercut or beveled, as shown, one of said walls being designed to contact withthe adjacent base-flange of the rail seated in said recess, and between the opposite base-flange of the rail and the other undercut wall is provided an intervening space designed for the reception of a railclamping wedge member 9, the length of which is substantially equal to that of the recess 7. The wedge member 9 is provided on one side throughout its length with a bevel-face 10 to correspond with that of the bevel of the abutting wall of the recess, and its opposite side is provided with a cut-away portion 11 to match and fit the contiguous face of the baseflange of the rail, as shown. From this construction and arrangement it will be seen that the rail is secured to the tie by an interlocking wedge member requiring only one spike 12 to prevent its displacement.

l3 designates an elastic memberof a size and shape to it flush within the shell or tie 6, and said member consists of compressed cork and when introduced in said shell is prevented from displacement by the spike 12, This elastic member serves primarily as a cushion when the shell or body portion of the tie is subject to the stress of compression under the load imposed by the rolling-stock passing thereover in that it tends to relieve any injurious action or strain of such compressing force, as well as aiding the reaction of the resilient shell in recovering its natural lines of structural adjustment upon the removal of the load, and thereby serves to prolong the life of said tic. The elastic member also serves to deaden the sound ordinarily occasioned by the passage of the rolling-stock over the metallic tie.

Having thus described my invention, what I desire to claim as new and useful is- 1. A cross-tie comprising a metallic shell, having rail-receiving recesses in its upper surface, an elastic member adapted to fit within said shell, 2. rail-clamping wedge for clamping a rail to the tie within the recesses and a spike for holding, respectively, from displacement, the said clamping wedge and elastic member, substantially as described.

2. As an article of manufacture, a cross-tie eomprisinga metallic shell, anda compressedcork member arranged to slidingly fit within said shell. 4

3. A metallic railroad-tie, having receivingrecesses on its top surface, adjacent to its outer ends, provided with undercut or beveled walls, in combination with a rail to engage one of said recesses, and clamping wedge members arranged to slide in the intervening space between one of the walls of said recesses and the contiguous base-flange of therail, and a spike for holding the said wedge member from displacement, as set forth.

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

JOHN A. GUILER. Witnesses:

H. A. GROW, R. W. CADDELL.
