M ETALLIC RAILROAD-TIE.

SPECIFICATION-'forming part 0f Letters Patent N0. 633,673, dated September 26, 1899.

Y Application filed April 6, 1899. Serial No. 711,916- (No model-l To all wil/0711, it 77mg/ concern:

Be it known that l, JAMES B. WALKER, a citizen of the United States, residing at'Rush Springs in the Chickasaw Nation, Indian Territory, have inventedV certain new and useful Improvements in Metallic Railroad- Ties; and I do 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.

The :invention has relation to metallic railroad-ties; and the objectis to provide a tie of this character which will be simple of construction, comparatively inexpensive of production, and practically indestructible.

A further object is to provide simple and effective means for connecting the rail to the tie, whereby the same will be prevented separating or moving out of alinement.

To these ends the invention consists in cerof parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a perspective view of my improved railroadtie. Fig. 2 is a top plan View of a portion of the tie, showing the chair. Fig. 3 is a det-ail perspective View of one member of the chair removed, and Fig. 4 is a similar view of the other member of the chair removed. Fig. 5 is a longitudinal sectional view through the tie, rail, and chair. Fig. 6 is a similar View of a modification. Y

In the drawings, l denotes a metallic railroad-tie, preferably hollow and cast in one piece, although itisv evident that the base of the tie may be separate from the body portion and secured thereto by riveting, as shown in the drawings.

2 denotes the chairs of the tie. Each chair' consists of two sections a l). The section d is a fiat plate having downwardly-projecting arms 3,' which embracethe sides of the tie, and an upwardly-projecting knee 4, adapted to abut against the base of the rail. The sec- .5 to secure the parts in position.

cross-piece ZJ' being provided with a knee Z22, Which acts inl conjunction with the knee of the other section of the chair to hold the rail 5o in position. The ends of the cross-piece b have extensions c, adapted to fit between the sides of the tie and the downturned arms of the section d and to receive a through-bolt 6 denotes a second bolt which passes 5 through holes in the opposite ends of the arms c and through the tie to fasten the cross-bar b down firmly against the base a, of the chair, thus distributing the strain incident to pass- 6o ing trains between both bolts, and thereby materially increasing the life of the chair.

The construction shown in Fig. G is especially designed for curves. In this construction I extend the knee b2 upwardly a greater 65 distance than the knee 4 and against the tread of the rail to receive the side thrust of the rail incident to the train rounding a curve.

It will of course be understood that various changes in the form, proportion, and the 7o minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what 75 is claimed, and desired to be secured by Letters Patent, isv l. The combination with a tie,of a chair consisting of two sections, one section formed of a plate having downwardly-projecting per- 8o torated ears and a rail-engaging knee, and the other section having horizontally-projecting arms and a rail-engaging knee, and bolts, one of which passes through the overlapping ends of 'the arms and ears and the 85 tie, and the other of which passes through the arms at their inner ends and through the tie, substantially as and for the purpose `set forth.

2. The combination with 'a hollow metallic 9o tie, of a chair consisting of two sections, one section formed of a plate having downwardlyprojecting perforated ears and a rail-engaging knee, and the other section having horizontaHy-projeeting arms and at rail-engaging In testimony whereof I have hereunto set knee, and bolts, one of which passes through luy hund in presence of two subserbiug witthe overlapping ends of the arms and ears messes.

und rthe tie, and the other of which passes through the arms at theirl inner ends and Vinuesses: through the tie, substantially as and for the O. O. BURT,
