Application filed January 28, 1913.

Specification of Letters Patent.

Patented Mar. 1.0, 191d. Serial No. 744,729.

To all whom it may concern Be it known that I, SIGMUND FRIEDMAN, a citizen oil the United States, and a resident of Gorgona, Canal Zone, Panama, have invented a new and Improved Rail-Tie, of which the following is a full, clear, and exact description.

My invention relates to improvements in railway ties, and means for securing the rails thereto, and the object thereof is to produce a tie which will be so shaped as to obviate all likelihood oi the tie moving or working out of place when it once cmbeddcd in the earth, and be provided with a suitable seat by means of which the devices which grip the rail can be firmly fastened in proper position.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of retierence indicate the same parts in all the views.

Figure l is a view of one end of my tie showing a rail in section fastened thereto; Fi 2 is a top plan of the part shown in lijig. 1; Fig. 3 is a. sectional view on the line 3 3 of Fig. 2; and Fig. 4.- is a perspective view ot one part of the rail chair which the tie carries to fasten the rail thereto.

The body of my improved tie 1 is preferably made of concrete and is given such a shape as to be trapezoidal in cross-section, with the narrower 't'ace serving as the bottom. The rail 2 rests upon the top of this tie at either end, and I em 'ihjiy a rein'lorcing netting 3 arranged in the term of a tube and extending substantially from one end of the tie to the other to make the tie stronger. The netting of course may extend only a part ot the length o'l. the tie, for example, along the middle thereof, or the section between the rails if desired.

The under side of the tie is made eoncave, as shown at t, this concave section ex tending between the rails and serving when the tie is embedded in the ground to prevent the body thereo't :li'rmn moving or working cndwisc. At the same time, the tapering side of the tie gives a greater bearing surface for tamping and facilitates the removal of the tie from the roadbed.

The ends ot the tie are provided with transverse recesses 5, and along the corners of these recesses extend undercut ribs (3, to provide a dovetailed fit for a cushioning block or wood filler 7. This wood tiller carries the rail chair 8. This rail chair is made up of a pair of rail braces 5), each ol which is cast on a base plate .10, these base plates resting upon the block T and being securely fastened to the same.

The base plates It) have inter-engaging edges and are bent down along the sides to form ribs ll having inturned projections 12 which pass under the wood tiller 7 and prevent the plates it) from getting out of position. The bottom of the reci-ss 5 dc pressed, as shown at 1; to provide the neces sary space between the bottom ot. this recess and the bottom of the block 7, as will be readily understood.

.l lach oil the plates 10 has a hole I l: in the flange 11, and a lug to adjacent the same. It also carries :1 lug 1(1, and the edge opposite the tlange 11 will be curved as shown at 17, to provide recesses and projections which give the inter-tilting engagement of the plates 10, above mentioned.

The plates 10 are titted together so as to cause their uneven edges to match, as shown in Fig. and are held in place on the wood tiller T by means of book bolts 18. These hook bolts have one end inserted into the holes ll, and will extend across the plates 10 inside the lugs 15 and pass through the perforated cars it). The ends o't these bolts will be threaded to receive nuts to lock the plates 10 together. The braces 9 will have holes l!) to allow the bolts to pass through them, i

The rail is held in place by means of rail braces 9, one of which cast upon each oi the plates 10, and which are shaped so as to engage the sides of the web 20 ot the rail beneath the top and hold it firmly against movement. It will be seen that the lugs 15 will prevent the movement of the adjacent end of the bolts '18 around the apertures lelas pivots, and thus the rail braces will be held tirn'ily against the rail.

The wood tiller is dove-tailed into the concrete tic, as stated above, and it may be driven out From either side \\'llt,1l('\"tl' it is necessary to replace it. lt does not bear for its whole length on the tie but only at its ends. This arrangement greatly increases the flexibility of support tor the rail chair and allows it to yield when the weight of a train passes over it.

The wire netting reinfla'ccment may be carried as far as the edge of the recess 5, and inverted U-shaped bars may be embedded in the tie at either end beyond the recesSes to take up the horizontal thrust along the rail when a train passes over it.

Preferably I construct the plates 10 with interlocking edges, so that the general direction of the recesses and projections on the edges 17 will not be parallel with the tie 2, but slightly diagonal with respect to the same. Consequently, when the plates 10 are drawn together by the hook bolts the plates 10 will not only be drawn to each other across the tie, but will move to some extent in a longitudinal direction, thus forcing the rail braces 9 firmly against the opposite sides of the web of the rail 20. To assist in obtaining this grip on the rail, the hook bolts are preferably placed at a slight angle.

By making the tie proper of concrete 1 secure an article which is practically indestructible. Furthermore, the wood filler offers a cushion for the rail and makes the tie more resilient than a solid wood tie, thus decreasing the wear on rolling stock and reducing the cost of operation.

All the parts that are subjected to stress can easily be replaced, and it will be observed that no part 01" the rail chair or any of its fastenings are embedded in the concrete. The rail chairs or any parts of the same may be removed or replaced without disturbing the rail or the tie either.

The construction of the rail chair distributes the pressure on the head of the rail over a large surface of the tie, this surface being considerably greater than the bottom of the base of the rail. The rail chair gives numerous advantages which are not obtained by means of spikes, as it offers a brace on the web of the rail and under the head thereof and prevents springing and breaking of the rail, due to excessive pressure on the side of the rail head. Furthermore, due to the braces 9, all creeping or spreading of the rails will be prevented.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. The combination of a tie having a recess in one end, a cushioning block secured in said recess, a pair of interengaging plates resting upon said block and having their sides bent over to engage the under side of the block, means for securing said plates together, and locking means carried by each of said plates to engage the sides of a rail and hold the same in position.

2. The combination of a rail having a re cess in its end, a cushioning block secured in said recess, a pair of plates having inter-engaging edges and having their sides bent over to engage the under face of the block to hold the same in place, a hook bolt secured to the side of each of said plates and extend ing across the same, lugs carried by said plates to receive the opposite ends of said bolts, means engaging said bolts to hold the same against displacement, and bracing members carried by each of said bolts to engage the sides of a rail beneath the top thereof to hold the same in position.

3. A rail chair, including a pair of companion members having interengaging edges, each 01" said members having a side flange which is adapted to lie flush with one side of a tie, and means for securing the members and retaining the same upon the tie.

4L. A rail chair, including a pair of companion rail-engaging members having interengaging edges, each of said members having a side flange which is adapted to be arranged against the side of a tie, inturned projections upon the flanges which enter the sides of the tie, and means for connecting the sections of the chair.

5. A rail chair including a pair of companion rail brace members, each formed of a casting, and each having interlocking inner edges, each of said members being provided with a side flange which is adapted to lie against one of the faces of the tie, means integrally formed with the side flanges for securing the same to the tie, and means for connecting the rail engaging portions of the chairs.

6. A rail chair including two interchangeable members each formed of a casting and each comprising a flat base having its outer edge flanged, the base being further formed with a rail brace member which includes spaced sides and a connecting member formed upon the inner edge of one of the said sides, each of the said base portions having its inner edge formed with recesses and projections which are adapted to interlock when the sections are assembled upon a tie, means upon the flanges for engaging with the sides of the tie, and means arranged between the sides of one of the rail engaging members and (Jo-acting with the flange of the co -acting member for removably connecting the sections.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. j
