METALLIC TRACK-FASTENING.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed August 2, 1913. Serial No. 782,739.

To all whom it may concern:

Be it known that I, FRANK JAGER, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Track- F astenings, of which the following is a full, clear, and exact description.

This invention relates to metallic track fastenings.

One object of this invention is to provide an improved metallic track fastening which can be easily and cheaply made and which possesses sufficient inherent strength to withstand the strains to which it is subjected when in service. Another object is the provision of a track fastening which is adapted to be quickly placed in position on a tie, and which also permits the ready removal of the latter and the replacement of another tie whenever desired.

A further object is the provision of a metallic track fastening which is adapted to prevent buckling of the rail. A still further object is to provide a fastening of this character designed to reduce the mechanical wear of wooden ties and thereby lengthen the life of the latter.

These, together with such other objects as may hereinafter appear or are incident to my invention, I attain by means of a construction illustrated in preferred form in the accompanying drawings, wherein:

Figure 1 is a plan view of a tie, illustrating the application of one embodiment of my invention thereto; a fragmentary portion of the rail being shown in position at the right of the figure.

Figure 2 represents an end view of the tie and rail fastenings with the rail inside view, and Figure 3 is a sectional view taken through the fastening shown at the right of Figure 1.

Figure 4 is a front elevation thereof.

Figure 5 represents a view in perspective of my invention, and Figure 6 is a similar view but illustrating a modified form, and

Figure 7 is an enlarged drawing in perspective of the rail brace.

In the drawings the numeral 8 designates a conventional wood tie and 9 represents a rail adapted to be fastened on the tie at a point adjacent the end thereof. Interposed between the rail base 9 and the tie is a metallic tie plate or chair 10 of substantially inverted channel shape designed to straddle the tie, and which has its horizontal Web 10 received in a cut away portion or recess 11 formed in the upper face therein. When thus positioned the web is approximately flush with the upper surface of the tie, and the end flanges 10 depend downwardly to occupy a position opposite its sides.

In the practice of my invention, I provide a filler block 13 having inclined vertical sides 13 which is inserted between one of the flanges 10 and the adjacent side of the tie; or if desired two blocks may be used for each tie plate, each wedging between one end flange 10 and the side of the tie as in the manner indicated in Figure 2.

A very effective arrangement for securing the plate to the tie without splitting the latter, as is the case when spikes are employed, is to fasten the plate thereto by means of the transverse bolt or bolts 1st which pass through the side flanges and the body of the tie at a point sufficiently removed from the upper surface, the bolts being secured in position by the nuts 12.

The rail seats on the major portion of the tie plate, and in order to prevent rail dis placement or spreading, I provide the upstanding lugs 15 formed on the web of the plate as in Figure 6, or, preferably struck up from portions of the web lying in horizontal rail seating portions in such a man ner as to leave the bridging strip 16 as in Figure 5, which forms an integral part of the rail support. The lugs are preferably disposed in parallelism to each other, and so placed with respect to the rail base as to permit ready placing of the rail when being aid.

To prevent angular movement of the rail, which as previously stated seats between the rail base retaining lugs 15, I provide a rail brace member 17 which may be of the preferred conformation. This preferred form of brace, as clearly shown in Figures 2 and 3, rests between the rail and lug 15, and seats upon the rail base flange 9 to extend upwardly therefrom in supporting engagement with the rail head '9. The brace is provided with inclined lower and upper wedge faces conforming with and adapted to wedge between the inclined upper surfaces of the rail base and lower portion of the rail head, respectively, which converge toward the web of the rail. In order that it may wedge in tightly between the rail base and head, the inner face of the brace is substantially concave and is not in contact with the web of the rail, but is spaced away therefrom so as to permit the wedging fit above referred to.

Referring more particularly to Figure 3 it will be seen that a slot 20 is formed in the outer face of the brace and that an annular opening or recess 18. is provided in the vertical wall of the slot. Within the slot is inserted a nut 19 whose threaded opening is designed to be in alinement with the opening 18, and a bolt 21 passing through the lug 15 and nut 19 has its shank end received within the opening 18. In this manner the brace, nut, lug, and bolt when assembled all cooperate to hold the rail firmly down on its-seat. In tightening the bolt to obtain the wedging fit of the brace with respect to the rail base and head, the operating nut 19 cannot turn with the bolt as it is locked withinthe upper and lower brace walls of the slot against any movement which may becommunicated thereto, and further takes against the lug which to all intents and purposes acts as a stop for the nut. In practice, it might be considered advantageous to employ a spring nut lock between the head of the bolt and the lug to prevent the former working loose, and to permit further tightening of the bolt.

The filler block 13, inserted between the tie plate flange and the side of the tire, readily permits the withdrawal of a tie on uncoupling the bolts 14, for without it the operation of withdrawing the tie for replacement of a new one would be difficult, in that the end flanges would inevitably grip or scrape the sides of the tie. With the fastening in position, this'operation contemplates aslight lifting of the rail by the usual means, when the plate will at once clear the recess 11 formed in the upper face of the tie and the filler blocks may then be knocked out of place. In the modification illustrated in Figure 6,the railbase engaging lugs 15 are shown formed on the plate, and the end flanges 10 are adapted to be receivedin vertical recesses formed in the sides of the tie.

The device'is designed to be easily and cheaply manufactured, the tie plate itself being formed from comparatively cheap rolled iron of channel section; or again simply made from a metal blank having its ends bent down to form the end flanges 10 and the lugs 15 out and pressed up in practically a single operation.

I do not intend to restrict myself to the precisedetails'ofconstruction, nor'for example to the exact form of railbrace as shown, for it is obvious that variations thereof may be made without departing from the spirit and scope of the claims appended hereto. The essential features-elements and operation of the device, together G'opies of this patent may be obtained for with its simplicity and other advantages thereof, will be clearly apparent to those skilled in the art.

' Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the fol lowing:-

1. A fastening for flanged rails comprising a rail retaining lug disposed to one side of the rail base and extending upwardly therefrom, and a wedging brace disposed between the rail head and rail base, and provided with an inner face normally spaced away from the side of the rail and having a slot formed in its outer face, means to force the brace inwardly toward the rail consisting of a nut received in said slot and a bolt adapted to pass through the lug and the nut, substantially as described.

2. The combination with a rail, of a rail seat member having an abutment adjacent thereto, a recessed brace member interposed between the abutment and the rail and adapted to engage the rail, a nut in the re cess in the brace, and a bolt passing through the abutment and nut to engage the brace.

3. The combination of a rail, a rail seat member having an abutment adjacent thereto, a recessed brace member between the abutment and the rail, a nut non-rotatably held in the recess in the brace, and a'bolt passingthrough the abutment and nut and engaging the brace.

4.. In combination, a railway tie metallic chair having a body portion adapted to seat on the upper face of the tie and formed with side flanges depending from said body portion in a substantially parallel relation with the sides of'the tie, one of said side flanges being spaced away from the tie, and a filler block interposed and secured between the said side flange and the'side of'the tie, re moval of which permits the endwise withdrawal of the tie out, of contact with the said side flanges. p

'5. In combination, a railway tie metallic chair having a rail-seating body portion formed with side flanges depending therefrom in a substantially parallel relation with the sides of the tie, one of said side flanges beings Jaced away from the side of thetie, a filler lock interposed between the said side flanges and the'tie, and a transverse bolt passing through the flanges, filler block andtie, substantially as described and for the purpose set forth. 7 i In testimony" whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
