INVENTOR WILLIAM HENRY MORGAN, or ALLrANcE, OHIO.

RAILROAD-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed April 1, 1912. Serial No. 687,729.

To all whom it may concern:

Be it known that I, \VILLIAM H. MORGAN, a citizen of theUnited States, residing at Alliance, in the county of Starkand State of Ohio, have invented Certain new and useful Improvements in Railroad-Track Construction; 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 an improvement in railroad track construction, and is designed particularly as an improvement on the construction disclosed in the application for patent filed by A. C. Shand, May 17, 1912, Serial No. 697,927.

In, the application above referred to, the rails are supported on metal stringers extending longitudinally of the rails, and on straight ties located intermediate the stringers and projecting at the ends beyond the latter. Such construction is admirably adapted for steam roads where the trafiic is light, and for street railroads, and is comparatively inexpensive in its construction. The principal objection to it, is, that, as the rails have but limited bearing on the cross ties, which are the sole means of lateral support and between the rails,-there is a tendency for the ties to turn or pivot more or less under an unequal longitudinal creeping movement of the rails, and the object of my invention is to provide means for holding the track square and the rails at proper %Vith this object in view my invention consists in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in plan of a section of a track embodying my invention and Fig. 2 is a view in section on the line A-B of Fig. 1.

VVith this object in view my invention consists in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in plan of a section of a track embodying my invention and Fig. 2 is a view in section on the line A-B of Fig. 1.

My improved track is composed of a series of cross ties 1, and stringers 2, located intermediate the cross ties and extending approximately from one cross tie to the other, and supporting the rails between said ties. These cross ties and stringers, are preferably made of old and discarded railroad rails, but may if desired be made from new material, and are both substantially I- shape in cross section, the base flanges 3 being wider than the top flanges 4, and preferably inclined downwardly, or concaved on the underside so as to form a housing, un der, or within which, the ballast-will pack when tamped. The cross ties, instead of being straight as in the application above referred to, are Zshape as shown, the parallel side members 5, extending in the dlrection of the length of the rails and constituting supports for the latter. These side supports of the Z-shaped ties are considerably longer than the width of the straight tie, hence they form elongated bearings to which the rails may be rigidly secured and when so arranged, there can be nopossible movement of the rails that could destroy the alinement or the gage of the track. 4

The rails are supported on chairs 6 which latter are provided with dependin flanges 7 overlapping the opposite sides 0 the top flange of the stringer and top flanges of the parallel members of the tie, and with upwardly projecting flanges 8 which engage the side edges of the base flange of the rail, and the rails are secured on the chairs by the spring clips 9 which latter engage ribs 10 on the armor plates 11, under the top flange 4 of the stringers and ties, and bear at their upper ends against the base flanges of the rails, the said plates 11 bein held against outward displacement by t e depending flanges 7 of the chairs 6.

As s own in Fig. 2, insulating material 12 is interposed between the stringers and ties, and the chairs, and between the armor plates 11 and the top flanges of the stringers and ties. When the ties and stringers are made of old rails, the base flanges of the rails form the top flanges of the stringers and ties, and the heads of the rails which are flattened out and arched, form the base flanges of the stringers and ties. For street railways and for steam roads over which the traffic is comparatively light, the stringers would preferably be the length of an ordinary rail; for heavier trafiic the distance between the ties could be shortened up.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In railroad track construction, the combination of rails, Z-shaped ties the parallel members of which form the rail supports,and straight stringers supporting the rails intermediate said ties, the said ties and stringers being substantially I-shape in cross section. v

2. In railroad track construction, the combination of rails, Z-shaped ties the parallel members of which form the rail supports, and straightstringers supporting the rails intermediate said ties. a

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
