MEANS FOR FASTENING RAILS T0 TIES.

Application filed September 13, 1916.

To all whom it may concern.

Be it known that I, Fnrrz BAunror-rrnn, a subject of the King of Prussia, German Empire, residing in Osnabriick, Germany, have invented a new and useful Improvement in Means for Fastening Rails to the Ties, of which the following is a specification.

With rails having tie-plates and fastening-plates on ties it is found to be unsatisfactory, in that the fastening-plates pressing on one end tight on the rail-fiange and on the other end against the inclined rib of the tie-plate are not in exactly horizontal position as soon as the smallest deviations from the correct shape are caused by faults in manufacturing or by wear. The fastening-plate does not touch the rail flange nor the rib of the tie-plate on a surface but on a line, whereby the wear rapidly increases. To make it clear, if the fastening-plate is sitting a little lower at the rail-flange than on the inclined rib of the tie-plate, the rib is touched by the fastening plate only at its lower edge; on the other hand, if the fastening-plate is lower at the inclined rib than on the rail-flange, the fastening-plate touches the rib only at its upper edge. F urthermore it is a disadvantage with tie-plates having an outer rail-flange overhanging portion, that the rail is usually not pressed down on the tie-plate by this overhanging portion on account of the inaccurateness of the manufacturing processes because the overhanging portion of the tie-plate must be made sufliciently highto permit the entering of the thickest rail-flange.

My invention will do away with all these troubles by giving not only to both sides of the rail-flange but also to the inclined rib as well as to the outer overhanging portion or rib and to both sides of the fasteningplate fiat contact surfaces inclined under a proper angle with easy means of adjusting and tightening up the plate. In this manner the play between the rail-flange and the lower surface of the outer overhanging rib is done away with, because the rail in tightening the fastening-plate at the inner rail-side by means of the pressing down screw is pressed and held tight at once on both sides by large surface contacts, without any possibility of the fastening-plate changing its horizontal or vertical position. The fact that large and close surface contacts are assured prevents practically any wear Specification of Letters Patent.

and therefore very rarely retightening of the screws is necessary.

In the accompanying drawings- Figure 1 is a side elevation of a tie plate for wooden ties embodying my invention and showing the rail in place, and in section.

Fig. '2 is a like view of a. tie-plate used in connection with metal ties.

Fig. 3 is a view similar to Fig. 1, showing the use of fillers for enabling the clamp ing of rails of the customary form.

Fig. a is a view similar to Fig. 1, showing a modification.

Fig. 5 is a like view, similar to Fig. 4, showing the use of two clamping plates.

Fig. 6 is a View similar to Fig. 5, in which the tie plate beneath the rail foot is entirely omitted.

Fig. 7 shows the structure of Fig. 6 used in connection with a wooden insert beneath the rail foot.

Fig. 8 is a view similar to Fig. 4-. of a tie plate for metal. ties.

Fig. 9shows a structure similar to Fig. 5, adapted for metal ties.

Fig. 10 shows a structure similar to Fig. 6, adapted for metal ties.

Fig. 11 shows a wooden insert under the rail foot used in connection with the structure illustrated in Fig. 10.

In'Fig. 1 a is the rail, 6 the tie-plate, 0 the fastening-plate, a?) the inclined side con tact surface between a and b, and in the same manner ac and be are the surfaces between a and c, and between Z) and c. The contact-surfaces ab and a0 are symmetrically inclined and have the angle which is customary with the inner inclined rib of the tie-plate.

'lhe'dotted lines show the symmetrical arrangement of the inclined side-surfaces. It is clear that the rail through this arrangement is simultaneously pressed vertically and horizontally into the seat, thus taking up all strains and shocks in all directions with the same security and thereby holding the rail-flange absolutely tight and preventing wear and tear. The important feature of the invention is that the angle must be exactly the same on the rail flanges as on the side ribs of the plates to insure perfect surface contacts. On the other hand all the troubles caused by inaccuracies of the thickness and of the width of the rail-flange, the height of the over-hanging rib at the outer end of the tie-plate, the width and thickness of the fastening-plate, the distance between the inner and outer ribs of the tie-plate are entirely eliminated. It is important in this invention that it is easy to make the angle of the inclined contact surfaces accurately but it is diificult if not commercially impossible to manufacture in large quantities parts of exactly the same dimensions as result of some parts, rails and so on, running at much lower temperatures through the rolling mill than others.

In Fig. 2 the steel-tie is indicated by s.

The construction shown in Fig. 3 is especially intended for rails of common shape alreadyin use on the track in order to make it possible to use the new system of fasten-- ing on old rails with rounded flange sides.

For this purpose pieces 6 must be inserted between the rail flange on one side and the outer rib of the tie-plate and between the rail-flange on the other side and the fastening plate. Of course, the construction of Figs. 1 and 2 is preferable.

In Figs. a to 11 some variations of the rail and fastening of Figs. 1 and 2 are shown, the main difference being that below the inclined contact surfaces at the side of the rail flange there are small Vertical surfaces. These vertical surfaces have the advantage that if two fastening plates (Z are used, one on each side of the rail, it is easier to mount the rail in line, as otherwise the fastening plate which is not yet screwed down could be lifted too high by the pres sure exerted by the other fastening plate.

Figs. 4 to 7 show the arrangement for wood ties, Figs. 8 to 11 for steel-ties. Figs. 4:, 5, 8 and 9 show constructions with iron tie-plates, while Figs. 6, 7 10 and 11 show constructions without iron tie-plates but with support pieces 9 on each side, each having the inclined side surface for the fastening plates (Z. The hooks i and 71:, Figs. 8 to 11, keep the tie-plates b or support'pieces g in position on the ties.

What I claim and desire to secure by Letters Patent is:

1. Means for fastening a rail to a tie by a tie-plate, having on one side of the rail an inclined rib, a fastening-plate between the rail and this inclined rib and at the other side of the rail a hooked rib, both side surtie-plate, in such manner, that the rail-flange is held tight vertically and horizontally.

2. Means for fastening a rail to a tie by a tieplate having on each sideof the rail an inclined rib, a fastening plate at each plate at each side of the rail between the rail and the inclined ribs, both side surfaces of the rail-flange and the contact side surfaces of the fastening plates engaging the rail being flat and inclined corresponding in angle to the flat and inclined contact surfaces between the fastening-plates'and the inclined ribs of the support-pieces, in such manner that the rail-flange is held tight vertically and horizontally.

4. In a rail fastening, two abutments between which the rail is adapted to rest, both having securing faces the upper portion of which forms an acute angle with the rail supporting surface and the lower portion of which is substantially perpendicular to said surface, and a wedge-shaped clamping member for cooperation with an edge of the rail foot and with an abutment, the operating faces of said member being substantially parallel on their lower portions.

5. The combination with a railway rail having beveled edges on its foot; of fastening members having correspondingly beveled edges.

6. The combination with a railway rail having beveled surfaces on the upper portion of the foot-edge and substantially vertical surfaces beneath the beveled surfaces; of fastening members having like beveled surfaces beneath which are surfaces substantially perpendicular to the rail supporting surface.

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