Specification of Letters Patent. Patentgd Egg, 1'? 19112, Application filed September 16, 1912. Serial No. 720,659.

To all whom, it may concern:

Be it known that I, James T. ANDREW, a citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain new and useful Improvements in Gross- 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.

My invention relates to improvements in railway ties and similar articles, and it consists in the constructions, combinations and arrangementsherein described and claimed.

An objectof my invention is to provide a strong and durable cross tie constructed of a plurality of sections of timber of less size than is at present available for ties, thereby providing'an inexpensive construction, in whichrelativel-y small timbers canbe efiiciently utilized.

A further object of my inyention is to provide an improved cross tie constructedof a plurality of sections of timber, and in which any section can be independently replacedby a new section, thereby enabling the tie to be repaired'and local defects or deteriorations removed without discarding the entire tie.

A further object of my invention is to provide an improved cross tie constructed of a plurality .of sections of timber securely clamped together, thereby providing an improved tie which can be thoroughly and uniformly' creosoted, vulcanized, or otherwise treated, by subjecting the several sections to the desired treatment before clamping them. together. v

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the sereral views :-Figure 1 is a perspective view, illustrating one embodiment of my invention; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary plan of one end of a tie showing a modified form of clamping washer; Fig. 4 is a section on the line 4.- 4t of Fig. 3; and Fig. 5 is a plan view of a section of track employing my improved tie.

Referring to the drawing, 1 indicates sections of timber extending longitudinally throughout the length of the tie, and abut ting along common vertical planes 2 and horizontal planes 3. The several longitudinally-extending sections 1 are firmly clamped'together by keepers 4 driven transversely into the abutting faces of said sec'- tions and engaging the outer faces of the latter. I have shown said keepers comprising bolts driven transversely through the tie along the vertical and horizontal abutting faces of the sections 1, and provided with washers 5 clamped firmly against the outer faces of said sections.

Figs. 3 and 4 illustrate a slight modification, in which oval or elongated clamping members 6 are substituted for the washers 5, foroverlapping the outer faces of the tie sections 1 to a greater extent. 'If desired, the washers 5 and clamping members 6 may be provided with sharp teeth or projections on their innerfaces for engaging the outer faces ofthe tie sections.

From the above description, it will be understood that my invention provides a strong and durable cross tie which can be inexpensively constructed of timber of less size than is at present available for ties, and in which any of the sections can be independently replacedby new sections for removing local defects without entire tie.

I claim 1. A cross tie comprising agroup of abut, ting, longitudinally-extending sections, and means for tying said sections together, comdiscarding the prising keepers driven transversely into the abutting faces of said sections.

2. A cross. tie comprising a group of abut ting, longitudinallyextending sections, and bolts driven transversely into the abutting faces of said sections and engaging the outer faces of the latter.

3. A cross tie comprising upper and lower pairs of longitudinally-extending sections abutting along common vertical and longitudinal planes, and means for tying said sections together, comprising keepers driven transversely into the vertical and horizontal abutting faces of said sections.

4. A cross tie comprising upper and lower In testimony whereof, I aflix my signa- -pan-s of longltudinally-extending sections ture, in presence of tWo Witnesses.
