Abstract: A railway spike for connecting an associated metal member with an associated wood member includes a head including an annular flange and a standoff extending axially from the flange. An intermediate section extends axially from the standoff. At least one holding ring is disposed on the intermediate section. The at least one holding ring extends radially away from the intermediate section and is adapted to engage the associated wood member. A shank extends axially from the standoff. The shank includes a thread which is adapted to engage the associated wood member.

Abstract: The invention relates to a plastic screw plug (6) for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region (7) which preferably adjoins a plug crown (8) toward the bottom, and in the continuation of which stem region (7) has an outer thread (9) with which it can be turned out of or into the sleeper, and is provided with an inner thread (10) underneath the stem region (7) in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way.

Abstract: Concrete sleeper with fixing elements incorporated, insertable or inserted into a sleeper body for fixing rails, wherein the sleeper body of the concrete sleeper (1, 18) has at least four apertures for fixing elements per rail (5) to be fixed, the apertures being arranged in pairs to the left and right of the rail support area (2), the two apertures for fixing elements of one pair being arranged staggered in the longitudinal direction of the concrete sleeper (1, 18).

Abstract: An improved fastener for attaching metal to wood is particularly suited for use as a railroad spike for attaching a metal rail to a wooden tie. The improved spike is adapted for installation by either driving or screwing the spike into the tie. A plurality of flutes are adapted to engage with the tie, thereby preventing loosening of the spike. The spike may be used with or without a metal boss or fishplate to secure a metal rail to a wooden tie.

Abstract: A screw thread having a threadform including a ridge rising from root to crest with the crest having two peaks, separated by a trough the depth of which is less than the height of the ridge from root to crest. It has particular use as a screw for timber, and is especially suited to fixing railway rails to sleepers.

Abstract: An expanding sleeve device for fastening a rail to a crosstie comprising a headed bolt threaded into a tapered nut. Positioned between the head and nut is a sleeve having radially expandable pronged portions and a deformable collar. The tapered nut causes the pronged portions and sleeve to expand and fit securely in a hole in the crosstie.

Abstract: A railroad plate and connectable shim are disclosed for fastening railroad tracks over ground having a flat or raised topography in an economically feasible manner. The instant system provides a base plate with a sloping grooved channel for reception of the lower flange of a rail to be held in place in combination with a trapezoidal shim to insure the proper cant of the rail over the various topographical areas of the country. The instant base plate, trapezoidal shim, rail and railroad tie are all fastened via a set of screws which are angled or toed-in towards the center of gravity of the rail. Stepped washers, each possessing a thickened portion, are provided between the bottom of the screw head and the upper shoulder surface of the lower flanges, both inside and outside the central vertical portion of the rail. The washers are omitted in securing back assemblies to the ties where joints are formed between the ends of adjacent rails.

Abstract: The device comprises a support such as a railway tie defining a projecting shoulder on each side of a support table for the rail. An insulating clip has a body cooperating with the shoulder and a nose portion bearing against the flange of the rail. An elastically yieldable strip is superimposed on the clip and a fixing bolt extends through apertures in the clip body and the strip. The clip body has, on the side of the body remote from the nose portion, a heel portion which defines two surfaces which bear respectively against a lower support surface of the support and against the shoulder. The clip body defines in the center part an upper surface which is substantially parallel to the strip. Beyond a predetermined tightening force the additional force is transmitted to the support through the body and the heel portion of the clip.
