RAIL-FASTENING.

Specification of Letters Patent.

Application filed February 3, 1911.

Patented May 16, 1911. Serial No. 606,423.

To all whom 'it may concern;

Be it known that we, TINFIELD SCOTT BARRETT and Ho-MER C. BosTIAN, citizens of the United St-ates, residing at Milton, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Fasten ings, of which the following is a. specification.

This invention relates to an improvement in rail fastenings, and the object is to provide a housing which is connected to a metallictie, and in which means is received for holding and gripping a spike as it is driven into the housing, in fastening a rail upon the tie.

The invention consists in certain novel features of construction and combinations of parts which will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure l is a View in perspective of the tie, showing that side of the housing to which the covering is fitted; Fig. 2 is a transverse vertical section taken between the end of the housing and the box; Fig. 3 is a transverse vertical section of the box which contains the metal bars; Fig. 4L is a sectional view of another form of metal bar which might be used in the box; and Fig. 5 is a modified form of spike, showing spurs upon two diagonal corners.

A, represents a metallic tie which is preferably made of malleable iron, and formed near each end of the tie is a housing 1, l, one end of the housing having a door 2 which is connected to the housing by means o-f bolts 3. The filler box 4L is received within the housing, and is provided with a plurality of layers of bars 5, preferably made of steel. The bars are stacked in the box in layers one layer running in one direction and the next layer extending transverse-ly of the layer below it, and so on until the box is filled, the bars being mounted in the box on their edges, and being of a length to ex* tend across the box either longitudinally or transversely. The tie is provided with holes 6, 6, at each end, directly over the box and a sufficient dista-nce apart to permit of the rail being received between the parallel holes, there preferably being two holes on each side of the rail. Spikes 7 7, are driven through the holes 6, and into the box 4,'

where they wedge between the layers of bars y5. `The bars are compressed within the box upon the entrance of the spikes, and the compression of the bars will produce a frictional grip upon the spikes, causing them to be securely held within the box and prevented from being raised, due to the vibration of t-he rail.` In instances where the tie is used on a curve, it is advisable to notch or place spurs on the spikes, so that the edges of the bars will engage the notches or spurs and hold the spikes against being raised, there being a greater tendency to cause the spikes to be raised on a .curve than along a straight stretch of track. In Fig. 4 we have shown a form of bar which can be used, showing the edges beveled, as at 8, and in Fig. 5 we have disclosed a spurred or notched spike. In this invention it is advisable to use a pointed spike, so that there will be no interference in the driving of the spikes into the box between the layers of bars. i

From the foregoing it will be seen that when the spike is driven into the box, it will cause the bars of the dierent layers to be compressed, and the compression of the bars creates an engagement between the bars and spikes which produces a gripping upon the spike at different points throughout the length of the spike which is received in the box. Therefore, when all of the spikes are driven into the box, the bars will become so compressed that the grip which is obtained upon the spikes by the bars will be such that the spikes will be firmly and securely held within the box and prevented from being raised by any vibration of the rail.

The housings l1 prot-rude outwardly on each side of the tie beyond the central portion thereof and form a means for securely holding the tie in position, for the reason that the ballast is received between the housings located at each end of the tie and beneath the upper surface of the rail, so that the tie is firmly held in its position when set in the road bed and prevented from moving.

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

l. A rail fastening comprising a tie, a box carried by the tie, a plurality of layers of bars mounted in the box for enga-ging and holding the spikes in the box when the spikes are driven into the box for fastening a rail upon the tie.

2. A rail fastening comprising a tie, a box carried by the tie7 and a plurality of layers of bars received Within the box, each alternate layer of bars extending transversely of the adjacent layer, whereby a spike Will be securely held by the bars when driven into the box.

3. A rail fastening comprising a tie, a housing formed on the tie, a box received Within the housing, and a plurality of layers of bars received Within the box for griplping and holding a spike when driven through the tie and into the box in securing a rail upon the tie.

4. A rail fastening comprising a tie, housings formed at each end of the tie, a box received in t-he housing, a door connected to the housing for confining the box in the housing, and a plurality of layers of bars received in the box for engaging the spikes as they are driven into the box in securing a rail upon the tie.

In testimony whereof We aiix our signatures7 in the presence of tWo Witnesses.
