and I do declare the following to be a full,

clear,-; and exact descfiption'of the invention;

such as will enable others skilled in the art to which it appertains to make and" use the same.

This invention relates to improvements in metal railway ties.

One object of the invention is to provide a metal railway tie having improved means for supporting the rails and means for fastening the same to a tie.

Another object is to provide a railway tie of this character which will be strong, durable and inexpensive in construction, reliable in operation and which will effectually prevent the rails from spreading or upsettin II ith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a side view of my improved tie, showing the rails thereon in vertical section; Fig. 2 is a top plan view of the same; Fig. 3 is a vertical cross section of the tie taken on the line 33 of Fig. 1. Fig. 4 is a similar view taken on the line 44 of Fig. 2; Fig. 5 is a detail perspective view of the lower side of one of the chairs or rail supporting plates of the tie.

My improved railway tie comprises a T- iron bar 1 of suit-able size and length. To the lower side of the bar 1 near each end or below the portions thereof with which the track rails 2 are engaged are secured rail supporting chairs 3 each of which comprises a plate having each end reinforced or increased in thickness on its lower side as shown at 4 and having in its upper side a longitudinal recess 5 corresponding in width to the width of the bar 1. In the plate 3 are also formed longitudinal centrally disposed slots 6 which are extended downwardly and form vertical recesses 7 in the reinforced ends at of the plate.

In the reinforced ends 4 of the Plate 3 on opposite sides of the recesses 7 are formed bolt holes 8 and in the ends of the bar 1 seasmg as eaare formed similarly ranged bolt holes" 9 which, when the plates 3* are'iri pla'ce on thetie'areadaptedto reg ister' with" the bolt holes 8 in the reinforced e'n'ds ofithepl'ate and with said registering bolt tales-n1 the tie l and plat'e's3' are en .gaged tie fastening bolts 10 whereby the .ends' of the tie are securely fastened to the lates*- or chairs 3. The bolt holes 9 in the tie or bar 1 are preferably square to receive the squared upper ends and heads of the bolts 10 whereby the latter are held against turning when the nuts 11 are screwed into the lower ends thereof.

In the plates 3 on opposite sides of the slot 6 therein and spaced a suitable distance apart are pairs of bolt holes 12 and in the tie or plate 3 and in position to register with the bolt holes 12 are corresponding bolt holes 13 which when the tie is fastened to the plates 3 coincide or register with said bolt holes 12. The bolt holes 12 and 13 in the plate 3 and tie are preferably of rectangular form or have fiat sides and with said alined bolt holes are engaged rail fas tening bolts 14. The bolts 14: have rail engaging heads 15 which correspond in shape to the shape of the heads of the usual form of rail fastening spikes or are provided with lips 16 which engage the base flanges of the rail as shown. The body of the bolts 15 which engage the bolt holes 12 and 13 in the plates 3 and tie are rectangularv or correspond in shape to the shape of said bolt holes with which they are engaged and thus prevent the bolts from turning when the nuts 17 thereof are screwed onto the cylindrical threaded lower ends of the bolts. If desired the chairs or plates 3 of the tie may be separated therefrom by means of cushioning plates or strips 18.0f any suitable resilient material arranged between the tie and the chairs or plates 3, as shown.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

A railway tie comprising a T-iron bar,

rail supporting bars secured to the lower sides of the tie below the points where the rails engage the latter, said bars comprising plates having their ends reinforced on their lower sides and each having in their upper sides a longitudinal recess corresponding in width to and adapted to receive the upper portions of the tie and hav ing a centrally disposed longitudinal slot adapted to receive the depending member or rib of the tie, said slot extending down and forming recesses in the reinforced ends of the chair, tie fastening bolts engaged with the tie and with the reinforced ends of the chairs whereby the tie is securely fastened to the chairs and rail fastening bolts engaged with the tie and with the adjacent parts of the chairs in position to fasten the rails to the tie, said bolts having heads adapted to engage the base flanges of the 20 JOHN GRIFFIN.
