ITIPQYEY I Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRIEDRICH WILHELM WEBER, 0F BOCHUM, GERMANY, ASSIGNOR TO THE FIRM VER-EINIGTE STAHLWERKE AKTIENGESELLSCHAFT, OF DUSSELDORF, GERMANY ARRANGEMENT FOR SECURING RAILWAY RAILS Application filed June 13, 1927, Serial No.

The invention has reference to an arrangement for securing or fastening rallway rails, in which the base or flange of the rail is clamped fast by means of preferably wedge shaped parts which engage with bridges firmly secured to, or integral with, the sleepers or tie plates.

The invention consists in an improvement of this method of rail fastening by which the stability and reliability of Working are cosiderably increased. For this purpose the invention comprises securing by suitable means the wedges engaged over the base or flange of the rail and under the bridges, so as to preclude the possibility of the wedges getting loose even when the tracks have been in service for a long time.

In the drawings:

1 is a vertical cross section taken along line AB of Fig. 3, Fig. 2 is a side elevation, and Fig. 3 is a plan of an embodiment of the invention.

Fig. 4 is a vertical cross section taken along line AB of Fig. 6, Fig. 5 is a side elevation, and Fig 6 is a plan of a modification of the invention.

Fig. 7 is a vertical cross section taken along line AB of Fig. 9, Fig. 8 is a side elevation, and Fig 9 is a plan of a further modifica-. tion of the invention.

Figures 1, 2 and 3 show a method of securing the rails to the sleepers by means of wooden wedges. In these figures, a designates a wedge-shaped means, hereafter called a securing wedge which is inserted under each ridge b, in the manner shown by the drawings.

The bridges Z) are portions of the base late, one near each outer side of the rail base, which are raised from the rest of the base plate. The bridges are preferably integral with the base plate but may, however, be former by fastening suitable members to the outer side of the base plate by any suitable means.

The securing wedges a engage the lower flange 0 of the rail and are preferably provided with an upward extension. Wooden wedges g, which preferably have a crosssection as shown in Fig. 1, are driven between 198,580, and in Germany June 1 5', 1926.

the inner face 6 of the upward extension of the securing wedge a and the web I) of the rail, and also engage the lower flange c of the rail. Inner face e of each securing wedge is preferably roughened to prevent any slipping of the wedge 9 after it has been driven into p ace.

Figures 4, 5 and 6 show an embodiment of the invention similar to that shown in Figures 1, 2 and 3 in that an element is inserted between the rail and each securing wedge, which element exerts an outward pressure against the securing wedge. I

In these figures, which show the method of securing the rails at the joints thereof, fish plates are provided as is customary at rail joints, but these fish plates h are so shaped that they engage the lower flange of the rail and the securing Wedges. When these fish plates are bolted to the rail in the ordinary manner, they exert an outward pressure against the securing wedges a, thus locking the securing wedges a under the bridges b. The fish plates h fit so snugly that drawing their middle portions together by means of the customary bolts the upper and lower edges thereof are forced out so that the corresponding contour of the bottom edge is firmly pressed against the top of the wedge. In'Figures 4, 5 and 6 the fish plates are shown as engaging the lower flange of the rail and the top of the rail, but it will be understood that these fish plates may also engage the web of the rail, so long as they exert a wedge effect against the securing wedges.

Figures 7, 8 and 9 discloses a further modification of the means for locking the securing wedges a under the bridges b of the base plate. In this construction a screw bolt 71 is inserted between the web d of the rail and 90 each of the securing wedges a, a suitable recess for the end of the screw bolt 71 being provided in the inner face of each securing wedge. A nut is is mounted on each of said screw bolts and is provided with a point )5 which engages a small recess in the web of the rail, so that the effective length of the screw bolt can be varied by suitable rotation of the nut is so as to lock the securing wedges a beneath the bridges b. The drawings show 100 Lil LII

a square recess in the inner face of each securing wedge 02 for the respective end of each screw bolt but, of course, any other suitable recess may be provided.

The outer end of each securing Wedge a preferably rests upon plates Z Which are Welded to the base plate, but these plates Z may be omitted and the outer end of each securing wedge permitted to rest directly upon the base plate as shown in Figures 1-9 inclusive.

It will be seen from all the figures that the bridges are located close to the edges of the flangeso of-the rail, and by this means applicant ensures against the lateral displacement of the rail, the said bridges acting as guides for the rails What I claim and desire to secure by Letters Patent of the United States is: 1. An arrangement for securing railway rails to base plates, comprising bridges rigid with the base plate and adjacent the flange of the rail to prevent lateral displacement thereof, Wedge-shaped means engaging the bridges and the lower flanges of the rail, and means engaging the rail and exerting a pressure against the said wedge-shaped means for securing the latter to the bridges. 2. An arrangement for securing railway rails to base plates, comprising bridges rigid with the base plate and adjacent the flanges of the rail to prevent lateral displacement thereof, wedge shaped means engaging the bridges and the lower flanges of the rail, and

' threaded means engaging the rail and exerting a pressure against thesaid Wedge shaped means for securing the latter to the bridges.

3. An arrangement for securing railway rails to base plates, comprising bridges rigid with the base plate and adjacent theflange of the rail to prevent lateral displacement thereof, wedge-shaped means engaging the bridges and the lower flanges of the rail, and a screw bolt between the web of the railand the wedge-shaped means adapted to be adjusted so as to exert a pressure against said wedge-shaped means,
