Oct. 17, 1961 P. PANDE-ROLFSEN RAILWAY RAIL SECURING MEANS Filed July 25, 1957 INVENTOR.
wmsml, 00L e mules Z0 A-rrok eve A 7 AM PER PANDE-ROLFSEN This invention relates to fastening members for anchoring a railway rail and to rail-fastening arrangements employing such members. I
v According to one aspect of the invention, there is provided a fastening member for anchoring a railway rail, comprising :a length of resilient metal of rod form which has a thickness of at least 1 centimetre and which is bent so asto have, progressing from one end of the length of metal: to the other, a first portion which constitutes a substantially straight leg, then a second portion in the form of a reverse bend, then a third portion extending generally in the direction of said one end, then a fourth portion which extends from the third portion, generally to that side thereof upon which said leg is disposed, and constitutes a reverse-bend having a radius of curvature much larger than that of the second portion, and finally a fifth portion extending in the general direction towards the junction between the first and second portions.
vAccording to another aspect of the invention there is provided, in combination, a railway rail, a flange at the base of the rail, a fixed anchorage member disposed adjacent the rail, portions of said anchorage member defining a passage which extends alongside the rail, parallel .to the length of the rail, and is closed at the top and open at least at 'one end, a fixed, unyielding surface which, as seen from the rail, is disposed outward of said passage, and a fastening member, according to the last foregoing paragraph, having the first portion thereof inserted in said one end of the passage and the third and fifth portions bearing one upon the top of the rail flange and the other upon said surface.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made to the accompanying drawing in which:
FIGURE 1 is a View, in elevation, of a railway rail and anchoring means therefor, the view being taken in the direction of the length of the rail,
FIGURE 2 is a plan view of the parts shown in FIG- URE l, and,
FIGURE 3 is a side view, as seen from the right, of FIGURE 2.
In the drawings, a rail 1 has a flange 2 which is seated between a pair of ribs 3 forming part of a base plate. The latter is secured to a sleeper (not shown), for example by means of screws or spikes passing through holes 5 in the base plate.
The base plate is made of sheet material and the ribs 3 are formed by bending the sheet material. It is apparent from the drawings that beneath the ribs 3 are formed passages 6 which are open at both ends and extend alongside the rail and parallel with the length of the rail.
Also illustrated are two identical fastening members, each consisting of a bent length of so-called rod iron which, as is well known, is preferably in fact steel. Each fastening member can be regarded as consisting of five portions which succeed one another along the length thereof. These five portions are:
(1) A first portion which constitutes a straight leg 7 extending from the end marked 10 in FIGURE 2 to about the position of the dotted line marked 11.
(2) A second portion which constitutes a reverse bend 12 extending from the end of the leg 7 (at about the line States P e t 3,064,716 C Patented Oct. 17, 1961 11) to about the position of the line marked 13 in FIG- adopted.
(3) A third portion 9 which extends generally in the direction of the end 10 of the leg 7, that is to say generally downwardly as seen in FIGURE 2 (on the righthand side of the rail). This third portion extends from about the position of the line marked 13 to about the position of the line marked 14. The portion 9 in the illustrated example appears, when viewed as in FIGURE 2, to be straight and parallel to the leg 7, but the illustrated degree of proximity to the truly straight condition and the truly parallel relationship is not essential.
(4) A fourth portion 15 which extends from about the position of the line marked 14 to about the position of the line marked 16. The portion 15 extends generally to that side of the portion 9 upon which the leg 7 is situated, that is to say it extends generally to the right (considering the fastening member shown to the right of the rail in FIGURE 2), as distinct from extending to the left or purely upwardly or downwardly. The portion 15, as is apparent from FIGURE 1, does in fact lead slightly upwardly and then downwardly, as it extends laterally from the portion 9, in order to leave adequate space between the part 15 and the leg 7 for the latter to be'fitted in the passage 6 in the manner to be described.
(5) A fifth portion 8 which extends in the general direction of the junction (line 11) between the leg 7 and the portion 12. This is not to be taken as meaning that the portion 8 must point directly to the line 11 but that the portion 8 extends generally upwardly when viewed as in FIGURE 2. In the illustrated example, when the portion 8 is viewed in plan, it appears to be straight and parallel to the leg 7, but the illustrated degree of proximity to the truly straight condition and the truly parallel relationship is not essential. The radius of curvature of the reverse-bend portion 15 is greater than that of the reverse-bend portion 12, with the result that, considering the right-hand half of FIGURE 2, the portion 15 crosses the leg 17 and the portion 8 is consequently to the right of the leg 7.
In assembling the illustrated parts, the leg 7 of one fastening member is inserted in one end of one of the passages 6 and the leg 7 of the other fastening member is inserted in the opposite end of the other passage 6 so that the free ends of the two legs 7 extend in opposite directions. The two fastening members are driven home by hammering at the portions 12, whereupon each portion 9 will bear upon the top of the flange 2 and each portion 8 will bear very firmly upon the top of the base plate, which affords a fixed, unyielding surface outward of the adjacent passage 6, as seen from the rail. The fastening member will act as a lever having its fulcrum extending along the axis of the leg 7 and it will be appreciated that both upward and longitudinal movement of the rail will be resisted.
Instead of adopting the illustrated construction, the base plate could be dispensed with and the ribs 3 and passages 6 could be formed in the sleeper itself. The passages 6, in all cases, must be closed at the top, that is to say it must be impossible for the legs 7 to move upwardly. The fastening members described above will be made from metal rod having a thickness or diameter of at least 1 centimetre.
I claim:
