ALVA C. DINKEY, 0F PITTSBURG, PENNSYLVANIA.

METALLIC TIE.

To all whom it may concern.

Be it known that I, ALVA G. DINKEY, a resident of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Metallic Ties, of which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view showing a railway cross-tie having the rails of a railway track secured thereto, and constructed in accordance with my invention; and Fig. 2 is a sectional end elevation on a larger scale of the tie shown in Fig. 1.

My invention relates to metallic crossties used in the construction of the tracks of a railway and the object of the invention is to provide a strong and durable metal tie in which a broad substantial base or bearing surface is presented to the road bed and in which the metal is distributed so as to afford the maximum strength with the minimum amount of material. To that end, the invention consists in constructing a hollow metal tie having a flat top or rail bearing surface connected by substantially vertical walls with oppositely projecting flanges with the flanges extending on opposite sides of each of the side walls and forming the base of the tie.

In the drawings, 2. represents a rolled metal cross-tie having track rails 3, secured thereto. In the rail fastening shown, metal clips 4 are employed which are bolted in place to secure the rails to the tie, the clips being held in place by means of the securing bolts 5, suitable bolt holes being provided in the tie for this purpose. The manner of securing the rails may be varied, however, and any approved securing means may be employed for use with my improved tie.

The rail bearing surface 6 is preferably formed integral with vertically extending side walls 7 and the lower edges of the side walls are provided with oppositely projecting flanges 8, 8 The side walls 7, together with the top surface 6 and the inwardly projecting flanges 8*, form a hollow rectangular inclosure, while the flanges 8 project outwardlybeyond the side walls 7 so as to increase the width of the tie and in this way provide a wider bearing surface for the tie on the road bed of the railway track.

In the construction of the tie, I first form Specification of Letters Patent.

Serial No. 454,880.

a rolled metal shape which is substantially the same in cross-section as the commercial I-beam, in which the web portion connects oppositely projecting flanges which are located on the opposite edges of the web. The blank is then subjected to a bending operation in which the web is bent so as to form three sides of the rectangular inclosure, the flange portions 8 together with the three sides formed by the web portion, forming the four sides of the rectangle. The flange portions 8 project outwardly beyond the width of the tie defined by the substantially vertical sides 7 and in this way increase the width of the base of the tie.

In some cases, it may be found desirable to make the thickness of the top side 6 greater or less than that of the side wall 7, this change in thickness being effected during the rolling operation.

The advantages of my invention will be apparent to those skilled in the art. The tie can be easily and cheaply formed and when formed in the manner shown, a metallic cross-tie is provided having great strength with a minimum amount of material. The oppositely projecting flange portions pro vide a wide base and afford a large bearing surface on the ballast or road bed. The longitudinal opening through the tie permits of the rail-securing means being easily and quickly applied.

The ties are durable and may be formed in multiple lengths and afterward cut to the desired size. The opening through the tie may be filled with plastic or other material when desired or may be partly filled.

Modifications in the construction of the tie may be made within the scope of my invention. The vertical height of the tie relative to the width may be chan ed, the width of part of the flanges relatively to the other flanges may be varied and other changes may be made.

I claim A substantially U-shaped cross-tie of rolled metal,having rolled flanges projecting in opposite directions from each leg of the tie at substantially right angles thereto and in the same plane with one another, the top of the tie being flat to support rails, the inner flanges coming into close mutual proximity, which flanges, together with the top and legs, form a hollow substantially rectangular tie closed throughout its length arcuate bend, and a fillet between each leg and the top of the tie at the interior of the tie, substantially as described. 10 In testimony whereof, I have hereunto set my hand.
