WILLIAM E. OBRIEN AND EDWARD J. QUINN, OF KENOSHA, WISCONSIN.

RAILROAD-TIE.

Application led October 2,

To all whom t may concern:

Beit known that we, lVILLmMi E. OluinN and EDWARD J. QUINN, both citizens of the United States, and residents of Kenosha, in the county of Kenosha and State of lVisconsin, have invented a new and Improved Railroad-Tie, of which the following is a full, clear, and eXact description.

rlhis invention relates to reinforced concrete cross ties, and has reference more particularly to the class comprising a body formed by a plurality of longitudinal and transverse members embodied in concrete.

An object of the invention is to provide an inexpensive tie, simple, strong and durable in construction, which will form a solid support for the rail and oil'er proper resistance tothe variable stresses produced by the rolling stock and atmospheric conditions.

A further object of the invention is to provide a concrete reinforced tie adapted to receive a railway plate and lock, and rigidly maintain said plate with the rail on the surface of the tie.

A practical embodiment of the invention is disclosed in the structure illustrated in the accompanying drawings forming part of this specification, in which like characters of reference indicate corresponding parts in all the views, and in which- Figure l is a side elevation of an embodiment of our invention, partly in section, showing the reinforcing longitudinal and transverse members near the vertical surface of the tie; Fig. 2 is a plan view of the same, also partly in section, showing the rein4 forcing bars near the horizontal surface of the tie; Fig. 3 is a cross section on the line 3 3 in Fig. l; Fig. 4 is a cross section on the line 4 4 in Fig. l; and Fig. 5 is an elevation of a Vertical supporting link.

Before proceeding to a more detailed description of our invention it will be understood that a cross section of the t-ie may be of any desired shape.

Referring` more particularly to the drawings, 10 are longitudinal parallel and horizontal bars, properly spaced, each diagonally opposite pair of these bars being supported by the diagonal cross bars 11, provided with an eye 12 at each end, and in which the longitudinal bars l0 are secured. By means of these eyes 12 the bars 10 are clamped to the diagonally crossing bars 1l. The vertically opposite pair of longitudinal bars l0 are inclosed and clamped in vertical links 13,

placed nlidway between two consecutive diagonal crossing pair of hars Ill, whereby a series of alternate diagonally crossing bars 'll and vertical links 1,3 is provided on the longitudinal horizontal bars '1.0.

The concrete 14; embodying the body and forming the tie is provided on its upper surface and. near each end with a recess l5, having two side surfaces 1G converging toward each other, and into which the lock of the supporting plate projects. Near the recess 15 two orifices 1T are provided, by means of which the rail supporting plate is fastened. Ihe recesses l5 are prismatoidal in form and in longitiulinal vertical section form a trapezoid, as can be easily seen in Fig. 2.

It is a well known fact that in a railroad bed there are always pockets formed under the ties that must be due to atmospheric conditions, and also to different elements constituting' the ballast that forms the bed, and to give to the tie sullicient elasticity to withstand these compound ilexures produced by the pockets and rolling stock the longitudinal bars l0 are intended. lVhile the diagonally crossing bars will transmit the pressure produced by the weight of the roll ing stock to all parts of thc tie, the vertical links 13 will increase the crushing resistance at the edges, and with the longitudinal and crossing bars form a homogeneously resisting body.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:-

l. A device of the class described, comprising a plurality of longitudinal parallel and horizontal bars, and an alternate plurality of crossing and vertical bars supporting said longitudinal bars in a predetermined position, the whole embodied in concrete to form a tie.

2. A device of the class described, comprising a plurality of longitudinal parallel and horizontal bars forming a rectangle in cross section, substantially diagonal crossing bars having clamping means at each end and clamping each diagonally opposite longitudinal bar, and vertical llnks clamping each pair of vertically disposed longitudinal bars, the whole embodied in concrete to form a tie.

3. A device of the class described, comprising a plurality of longitudinal parallel and horizontal bars forming a rectangle in cross section, alternately-disposed substanour names to this specification in the presence of two subscribing Witnesses. y
