. SPECIFICATION forming part of Letters Patent No. 423,586, dated March 18, 1890. Application filed July 24, 1889. Serial SO-318,489. (No model.)

To all whom it may concern."

Be it known that I, JOHN M. BAILEY, a citizen of theUnited States, residing at Goodson, in the county of Washington and Commonwealth of Virginia, have invented a new and useful Railway Cross-Tie, whereof the following specification, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to metallic cross-ties; and my object is to produce a tie which shall combine the desirable qualities of strength, durability, elasticity, lightness, and oh eapness.

The invention consists in the improved tie hereinafter described and claimed, and in the combination therewith of a chair, as also described and claimed.

In the drawings, wherein like letters of reference indicate like parts in the several figures, Figure 1 is a perspective view of a portion of a railway, two ties being shown in different positions with and without chairs. Fig. 2 is an end View of one form of the tie with a rail thereon. Fig. 3 is a similar view of the same form in a different position with a chair and rail. Fig. 4 is a sectional view on the dotted linezra: of Fig. 3. Figs. 5 and 6 are end views of slightly-modified forms of the tie. Figs. 7 and 8 are respectively a perspective and a central transverse sectional view of another form of the tie, and Fig. 9 is a transverse sectional view of still another form.

A and B indicate, respectively, the rails and the chairs, which may be of any preferred or usual form.

The tie O is formed from a plate or sheet of steel, preferably about one-fourth of an inch in thickness, which is rolled or bent longitudinally, as indicated at c 0' 0 &c., to form a series of approximate cylinders substantially parallel and adjacent one to another and arranged in substantially the same horizontal plane to form a broad bearing surface or surfaces for the rail or chair. The sheet may be of uniform thickness, or it may have the portion upon which the rail or chair will bear of a greater thickness, tapering to the normal thickness on either side, as indicated at c in Figs. 3 and 5 and at 0 in Fig. 2. 5

It will be found desirable in most cases, in order to secure greater firmness of the tie in cylinders. I prefer to bring the edge portions 0 of the sheet together, as shown in Figs. 2, 3, and 8; but when a broader bearingsurface for the rail or chair is required I may separate such edge portions 0 by a space, as shown in Fig. 5. In this case the sheet is formed with grooves c to receive the edges of the sheet and give greater firmness to the tie. I have shown the sheet as formed with such grooves; but this is not necessary in the form therein represented, as the bringing together of the edges gives sufficient firmness.

The tie may be used eitherside'up, as the convenience or the requirements of the particular use may dictate. When used in the position represented in Fig. 2, the rail-may be secured directly to the tie by clips a and bolts and nuts or rivets a, and when used in the position shown in Fig.3 a chair B may be secured to the tie by bolts or rivets b and the rail held to the chair by clips and bolts a a, as before. It will be observed that the tie represented in Fig. 5 may be used in an inverted position and a broad bearing-surface f for the rail be secured thereby without the interposition of a chair.

The specific form of tie thus far referred to, in which the middle portions of the sheet and the edges thereof when bent are perpendicular to each other and tangent to the circumference of the cylinders,-is employed when a bearing-surface of ordinary width is required.

In Figs. 6 and 9 I have shown two forms which may be given the tie when great width is desired. In the form shown in Fig. 6 the sheet is bent in S shape and the two partial cylinders closed in and the third formed by extending the sheet about itself, as. represented, the first edge 0 being received in a groove 0 and the second edge being secured to the body of the tie by a rivet Z). In the It will be seen that in Figs. 2, 3, and 8 form shown in Fig. 9 one cylinder is made by bending the sheet as represented at c and two others'by bending the outer portions of the sheet back upon themselves. The extreme edges 0 are again bent back in a line I with the top of thefirst cylinder to extend the bearing-surface.

By forming the tie from a single sheet of metal as a series of substantial cylinders I am enabled to take advantage of the well-known qualities of the cylinder to secure strength,

2. A cross-tie consisting of a sheet of metal bent or rolled to form two approximate cylinders substantially parallel and adjacent, having the middle portion of the sheet and the edges thereof perpendicular to each other and tangent to the circumference of the cylinders, substantially as shown and described.

3. A cross-tie consisting of a sheet of metal bent or rolled to form two approximate cylinders substantially parallel, having the middle portion of the sheet and the edges thereof perpendicular to each other and tangent to the circumference of the cylinders, and having the middle portion formed with grooves to receive the edges, substantially as shown and described.

4. A cross-tie consisting of a sheet of metal rolled or bent to form two approximate cylinders substantially parallel and adjacent, the said cylinders being made narrower and deeperlnear the middle portion of their length, substantially as shown and described.

5. The combination, with a cross-tie consisting of a sheet of metal rolled or bent to form a series of approximate cylinders substantially parallel and adjacent, of a chair secured to said tie, substantially as shown and described.
