DEVICE FOR PREVENTING THE CREEPING OF RAILS.
Sl-ECIFICAIION forming part of Letters Patent No. 716,207, dated December 6, 1902- Application filed August 15, 1902. Serial No. 119,719. (No model.)
To all whom it may concern..-
Beit known thatLHEINRIoH DoRPMiiLLER, royal traffic engineer of State railways, a-snbject of the King of Prussia,Emperor of Germany, residing at 36. Gasinostrasse,AiX-la- Ohapelle, int'he' Kingdom otPrussia, Empire rail-gibs, holding between them a doubletapered key abuttingaga'inst the base-plate of a rail-chair or any other means usedfor permanently uniting the rail with the sleepers, and in some cases in additionto this against1 the sleeper itself when the device is placed under the flange of the rail. If, however, it isdesirable to place the locking parts of the device upon the upper surface of the flange of the rail, then two wedges are employed, one at each side of the web of the rail, abutting against any of the means for permanently uniting the rail with the sleepers and bearing against the side of a gib placed in each of the loops of the clamp.
In the accompanying drawings, Figure 1 is an end View, Fig. 2 is a side view, and Fig. 3 is a view, of the device looking against the under side of the flange of the rail when the locking parts are placed under the rail. Fig. 4 is an end View, Fig. 5 is aside view, and Fig. 6 is a plan View, of the new device when said locking parts are placed upon the upper face of the flange of the rail.
This newdevice consists, chiefly, of a clamp a, gibs b, straddling said clamp, so as to be immovable endw ise, and a double-tapered wedge c placed between them, as most plainly shown in Fig. 3. After the gibs b have been put into place the clamp 19' isslid from the end of the rail 61 over the flange of the latter until it has nearly reached the place where it is intended to rest upon the flange of the rail, when the wedge c is placed into position, and then the clamp a placed where it is to remain for good and the clamp a given a blow sidewise, after which the ends of the loops 6 will rest upon the upper face and the top side of clamp almost touch the two edges f of the flange of therail, whereas the broader end of the wedge c is now abutting against a part of any of the means employed to secure the rail permanently to the sleepers as, for instance, the baseg of a rail-chair, as shown here by way of example. The creeping occurs in the direction of the moving train only and is supposed to take place in the direction of the arrows 72, Figs. 2 and 5. As the clamp ais secured. to the rail and the wedge c, abutting against a stationary part of the means, permanently uniting rail and sleeper and, in addition to this,
in some cases against the sleeper 1', too, as
indicated in Fig. 2, the tapered sides of the wedge 0 must of necessity forcibly engage the corresponding sides of the gibs b, and thus check thecreeping of the rail as soon as the rail shows an inclination for doing so. Hereby the enormous power developed by the -wedge will be resolved into two components acting at right angles to the direction in which the creeping takes place, as indicated by the arrows 7t and Z, Figs. 3 and 6, thus acting upon the gibs and pressing them sidewise and creating a high tension in the clamp, which tension will become all the greater the greaterthe efl'ort of the rail is to creep. Then, however, for any reasonswhatever itis desirable to place the device upon the upper face of the flange of the rail, then the wedge a must, so to speak, be divided and one-half of it placed to both sides of the web of the rail, whereas the gibs may retain their shape. This arrangement of parts is shown in Figs. 4 to 6, where the clamp a is provided with loops e, holding the gibs b. When now the clamp 01. has been slid over the flange of the rail, as described above, and the Wedges 0 been put in place, so as to bear against such parts as m n of the means uniting the rail with-the sleeper, the device will be ready to act at any moment the rail may show an inclination to creep.
It is evident that this device will work as well when the locking parts are placed under the flange of the rail as when placed upon it, the only condition being that the one end of the wedge in the one case and the ends of the wedges in the other case be placed against a part or parts of the means whereby the rail and sleeper are permanently united,'which among themselves again may differ in details, depending principally upon the nature of the sleepers-4.. 6., whether wooden or metallic sleepers. For the same reason it is obvious that it is of no consequence whether the sleepers used are solid or made hollow or have the shapes shown here or not, as these are only examples among others. As the wedges abut against the stationary parts of the means connecting said rail and sleepers or, in short, against the superstructure, the sleepers are compelled to take part in any creeping of the rail, and for the same reason it is possible to increase the resistance against creeping to the utmost by arranging such device near each sleeper, if necessary, thus compelling them all to take part in preventing suchcreeping. Ashiftingoftheclamplengthwise of the rail needs not to be feared, as the pressure exerted by the wedge would sooner destroy the clamp than shift'it. Should, however, it happen that here or there a device is getting loosened through the shaking of the rail caused by a moving train, it would with certainly get securely locked again by the next train creating in the rail an-inclination to creep.
I claim 1. A device for preventing the creeping of rails comprising a clamp embracing the flange of a rail, gibs placed between said flange of the rail and said clamp having each noses to prevent their leaving the clamp and an inclined working face, and a wedge or wedges bearing against said inclined working faces of said gibs and abutting with their free ends against a stationary part or parts of the sleepers of the railway.
2. A device for preventing the creeping of rails comprising a clamp embracing the flange of a rail, gibs placed between said flange of the rail and said clamp, having each noses to prevent their leaving the clamp and an inclined working face, and a wedge or wedges bearing against said inclined working faces of said gibs and abutting with their free ends against a stationary part or parts of the sleepers of the railway, in combination with the flange of a rail, sleeper, and means for permanently uniting said rail and said sleeper.
3. The combination with the flange of a rail and a sleeper of a clamp embracing the flange of said rail, gibs having inclined working faces held by said clamp and bearing with one side against the flange of the rail and with the opposite side against said clamp, a wedge or wedges bearing with their inclined faces against the working faces of said gibs and abutting against a part or parts of the means uniting said rail and said sleeper.
4:.- In a device for preventing the creeping of rails the combination of a clamp embracing the flange of the rail, gibs having inclined working faces held by said clamp and hearing against said flange, and a wedge or wedges abuttingagainsta part 01' parts of the sleepers of a railway and coacting with said gibs to prevent creeping of the rail.
5. In a device for preventing the creeping of rails the combination of a rail, a clamp embracing the foot of the rail, gibs straddling said clamp and having a wedge-shaped crosssection at right angles to the rail and another in a plane parallel to the flange thereof, a wedge or wedges cooperating with said gibs, a sleeper, and means for uniting said rail and said sleeper and serving said wedge or wedges as abutment.
6. In a device of the class described for preventing the creeping of rails, a gib having noses to prevent their leaving the clamp embracing the foot of the rail and having a wedge-shaped cross-section at right angles to the rail to bear against said clamp and the flange of the rail, and another wedge-shaped cross-section in a plane parallel to the flange of the rail for cooperating with awedge.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
