RAILROAD-TIE.

Specification of Letters Patent.

Application filed June '7, 1910.

Patented Oct. 18, 1910.

Serial No. 565,463.

1'0 all whom it may concern:

Be it known that I, JoHN TIEINONEN, a citizen of the United States, residing at Brush Prairie, in the county of Clarke, State of Washington, have invented certain new and useful Improvements in Railroad- Ties; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railroad ties, and particularly that type constructed of sheet metal. 7

The object of the invention resides in the production of a railroad tie of the character named which will be simple in construction, durable and efficient in use, and comparatively inexpensive to produce.

A further object of the invention resides in the production of a gib and key adapted for use in connection with the tie for firmly securing the rails thereto. I

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and described.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views; and in which,

Figure l is a side elevation of a railroad tie constructed in accordance with the invention, a pair of rails being shown securedthereto; Fig. 2, a section on the line 22 of Fig. 1; Fig. 3, a cross section of the tie showing the shape of the top section thereof before the latter is bent into interlocking engagement with the bottom section; Fig. 4, a top view of a fragment of a tie with the rail removed and the gib and key in the position they would occupy when in position to lock the rail in place; Fig. 5, a section on the line 55 of Fig. l; Fig. 6, a detail perspective view of the sections comprising the cross braces of the tie prior to securing said sections together; Fig. 7 a detail perspective view of a fragment of a tie showing the application of the cross braces to the interior of same; and, Fig. 8, a detail view of the metal blank from which one of the sections of the cross brace is constructed.

Referring to the drawings, the tie is shown as constructed of a base section A and a top section B. The base section A is formed of a piece of sheet metal bent so as to form upwardly diverging sides 10 and 11, the free ends of which are bent inwardly as at 12 and .13 respectively to form a substantial support for the top section B of the tie. Said top section when applied upon the free edges of the sides 10 and 11 is of trough shape formation and comprises depending parallel portions 1 1 and 15 which are bent inwardly so as to be disposed contiguous on the sides 10 and 11 respectively and thus lock the sections A and B together. The top section B is provided on its upper face with spaced grooves 16 and 17 which form seats for the base of the rails 18 and 19 respectively. Apertures 20 extend through the top of the section B on each side of the grooves 16 and 17 and have mounted therein gibs 21, said gibs having their shanks of such shape as to be capable of rotation within said apertures for a purpose that will be presently apparent. The lower end of the gib 21 is provided with a projecting lip 22, while the upper end thereof is provided with a projecting lip 23. By this construction it will be apparent that when the gib is rotated in the aperture 20 to the position shown in Figs. 4: and 5 the lip 22 will engage the under face of the top section B, while the lip 23 will overlie the base of the rail and thus securely lock the rail to the tie. In order to prevent rotation of the gib 21 after the same has been moved into interlocking engagement with the rail and tie a wedging key 24 is driven in the recess 20 at one side of the gib and is of such shape as to eflectually prevent rotation of the gib when thus inserted in the recess 20.

Disposed within the tie formed of the sections A and B at spaced intervals are the cross braces C which are formed of metal plates 25 and 26 having a shape substantially the same as the cross section of the tie. The edges of the sections 25 and 26 are bent laterally in opposite directions to form flanges 27 and 28 respectively which are disposed against the side of the section A and the inwardly bent portion of said section. Corresponding apertures 29 and 30 are formed in the plates 25 and 26 respectively and a rivet or bolt 31 extending through said apertures 29 and 30 serve to secure the plates 25 and 26 together and'thus complete the cross braces. These cross braces may be secured to the sides 10 and 11 by rivets 32 although such connection between the cross braces and the sides is not absolutely essential.

What is claimed is:

1. A railroad tie comprising a base section constructed of a piece of sheet metal bent to form upwardly diverging sides and a top member disposed upon and between the free edges of said sides and having its terminals bent downwardly and extending contiguous to the respective sides of said base member.

2. A railroad tie comprising a base section constructed of a piece of sheet metal bent to form upwardly diverging sides and a top member disposed upon and between the free edges of said sides and having its terminals bent downwardly and extending contiguous to the respective sides of said base member and having transverse grooves formed in the 1tjop face thereof for the reception of the rail ase.

3. A railroad tie comprising a base section constructed of a piece of sheet metal bent to form upwardly diver ing sides, a top member disposed upon an between the free edges of said sides and having its terminals bent downwardly and extending contiguous to the respective sides of said base member and cross braces disposed at intervals within the assembled tie, each of said cross braces being formed of a pair of connected metal plates having a shape corresponding to the cross section of the tie and their edges oppositely bent to form flanges.

In testimony whereof, I a'flix my signature, in presence of two witnesses.

JOHN HEINONEN.
