RAIL-TIE.

SPECIFICATION forming part of Letters latent No. 790,658, dated May 28, 1905.

Application filed January'l, 1905. SerialvNo. 241,419.

To /LZZ whom t 711/003/ concern.-

' material.

The kprincipal objects of the invention are to provide means secured in the tie for effectively holding the rail, for preventing the swinging of the rail on the tie, or vice versa, for strengthening the tie, and at the same time for permiting the tie to be readily placed in the roadbe Further objects of the invention will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view showing a portion of a pair of rails and a tie embodying a preferred form of my invention. Eig. 2 is a plan view thereof, partly broken away, and one rail being removed. Fig. 3 is a. sectional View on the line 3 3 of Eig. 2. Fig. 4 is a sectional view similar to Fig. 3 of another form of my invention, and Fig. 5 is a sectional view on the line 5 5 of Fig. 4.

The tie 10 is formed of concrete or other plastic materiaLwith a pair of slots or depressions 11 on the upper surface. These slots extend across the tie and are preferably of aV depth equal to the depth of the edge of the iiange of the rail to be used with the tie., They are also of a width equal to the width of the flange of the rail, and it is intended that the rail shall seat in these depressions. It will be seen that by this construction the sluing of the tie and spreading of therails are prevented and the two parts are effectively secured together against any angular or other motion with respect to each other.

The tie is preferably provided with a plurality of strenghening-bars 12, embedded in the tie in the act of molding and located with their upper surfaces at the bottom of the depression 11. These strengthening-bars preferably have bent ends 13 for more securely holding them in position. It will be readily understood that they can be applied to thel tie at other distances from the surface than that shown.

Located under each of the depressions 11 is a stirrup 14, provided with inwardly-projecting'feet 15 in the lower part of the tie. rlhe top of each stirrup is located on the plane of of the top of the tie and has a depression 16 extending to the bottom of the depression 11.

n When the rails are applied to the ties, they will rest in the depressions in the ties and stirrups and also, preferably, on the upper surfaces of the strengthening-bars. The stirrups are provided with perforations, through which bolts or screws 17 pass into the tie. The bolts can be threaded into the stirrups, or nuts 17a can be embedded in the concrete for their reception. These bolts aredesigned for holding clamps 18. The clamps are located with their lower surfaces upon lthe top of the tie and stirrup and also bearing upon the top of the flange of the rail. The bolts pass through the clamps and in an obvious manner secure them to the stirrups. The depressions 11 are provided with notches 19 for receiving the stirrups. Eyes 2O are provided for assisting in manipulating the tie and putting it into or out of place. A

In the form shown in Figs. 4 and 5 the 'stirrup 14L has outwardly-projecting feet 15L and is sunk below the surface of the tie throughout. The clamps 18 have only one bolt 17 and rest on the top of the tie. The other parts are the same as shown in the preceding views.

It will be seen that the rails are securely clamped in position on the stirrups and that they are effectively held against motion in all directions; also, that the tie is strong and unyielding in nature, although the rails can be readily loosened from it and the tie withdrawn from the road-bed without presenting any obstruction to its removal. It' will be observed also that the weight applied to the rail will be transmitted through the stirrup in two directions and will be supported by IOO the under side of the top of the stirrup and also by the feet, so that the area which supports the weight will be greatly increased by my invention. Furthermore,the entire weight of the rail is not supported by the stirrup, for it bears upon the concrete and tie-rods 12 upon both sides of the stirrup.

The stirrups and strengthening-rods are preferably formed of wrought-iron; but it will be understood that my invention is not limited to this material. The tie is molded in any desired manner; but I prefer to place the iask face downward with a bottom board. Across the bottom board, at the points where the rail-seats are to be located, a thin block or patternis placed. The stirrups are theninserted and the concrete or other plastic material poured in and tamped in the usual way.

While I have illustrated and described preferred forms of my invention, it will be readily understood that it is capable of embodiment in many other forms and that it is not limited to those shown.

Having thus described my invention, I claim as new and desire to secure by Letters PatentH 1. A rail-tie composed in the main of plastic material and having a stirrup embedded therein the stirrup having an upper surface located below the upper surface of the tie for the reception of the lower surface of a rail, a pair of clamps adapted to rest upon the top of the tie and on the top of the flange of the rail, and means for securing each clamp tothe stirrup.

2. A rail-tie composed in the main of plastic material and having a depression across the face thereof1 equal in depth to the depth of a flange of a rail to be applied to the tie, and having a stirrup embedded therein, an upper surface of the stirrup being located Hush with the lower surface of said depression.

3. A rail-tie composed in the main of plastic material and having a depression across the face thereof equal in depth to the Width of a Harige of a rail to be applied to the tie and having a stirrup embedded therein, an upper surface of the stirrup being located flush with the lower surface of said depression, a pair of clamps adapted to rest on the top of the tie on each side of a rail and on the top ol the flange of the rail, and means for securing each clamp to the stirrup.

4r. A rail-tie composed in the main of plastic material and having` a depression across the face thereof equal in depth to the width of a iiange of a rail to be applied to the tie and having' a stirrup embedded therein, part of the upper surface of the stirrup being located flush with the upper surface of the tie and having a depression located liush with the lower surface of said depression in the tie, a pair of clamps adapted to rest on the top of the tie and stirrup on cach side of a rail and on the top of the liange of the rail, means for securing each clamp to the stirrup, and a plurality of longitudinal streugtllening-hars enibedded in the material of the tie, their upper surfaces being in the same plane as the top of said stirrup.

5. A rail-tie composed in the main of plastic material. having a pair of depressions across its top, each being of the width and depth of the iiange of a rail and being located the same distance apart as the two rails of the track, a stirrup longitudinally embedded in thc tie under each of these depressionsand each having a portion of its upper surface coincident with the lower surface of one of the depressions, the depressions being provided with notches extending outwardly to receive the stirrups, a pair of clamps for each stirrup, said clamps resting on the top of the tie and on the flanges of the rails, and a bolt for each clamp passing through the clamp.

In testimony whereofl I have signed my name to this specification in the presence of two subscribing witnesses.
