Definitions

  • the invention relates to a steel band for wooden railway sleepers, having two overlapping band parts, whereof one band part has a plurality of slots and the other band part has a plurality of stamped-out oblique noses, which engage the slots of the overlapping band part and thus lock the band parts under tension. Since, for various reasons, these stamped-out oblique noses have to be arranged comparatively close behind each other, these noses are comparatively short, so that while they lock the two band parts together under tension, they do not secure the two band parts adequately against being lifted off each other. This lifting off and hence complete loosening of the clamping band may occur on shrinkage of the sleeper or also even if the band is not tightened sufficiently.
  • the present invention is based on the problem of making possible a satisfactory firm connection of the two band parts while obviating a special toothed fastener, i.e., in a clamping band of the simple type mentioned at the beginning, which connection prevents with maximum certainty loosening and lifting of the two band parts off one another.
  • the end of the nose band part has a securing nose, which is longer than the locking noses and is arranged obliquely in the op posite direction to these noses, on overlapping passes through a slot of the slot band part and is made so long, that after bending over it prevents loosening and lifting off of the band parts.
  • this securing nose arranged at the end of the nose band part, in this bending over, is bent back on the slot band part, that is to say, the angle of bend formed when this nose is stamped out is diminished again, there occurs, in contrast to the above-mentioned securing nose, no overstressing, but on the contrary, a strengthening of the nose by the cold work in bending back, the bending stresses produced on stamping out this securing nose being diminished or eliminated.
  • This securing nose provided according to the invention, therefore produces a reliable connecting together or securing of the two band parts against loosening and lifting off.
  • this securing nose produces such displacement of the two band parts relative to each other that the locking noses are pressed still more firmly against the slot band part, and the effect of the locking noses is thus assisted.
  • this second securing nose may be bent over in the opposite direction to the first securing nose, bending back being effected as in the case of the first nose, that is to say, the angle of bend is diminished, so that in this bending over, no overstressing of the nose occurs, but on the contrary, strengthening thereof.
  • This second nose secures the end of the slot band part additionally against lifting off.
  • FIG. 1 shows diagrammatically the compression and hooping of a wooden railway sleeper by means of a clamping band
  • FIGS. 2 and 3 show in plan, respectively, the two band parts of the clamping band provided with slots and oblique noses
  • FIFIG. 4 shows the front view of the nose band part of FIG. 5 is a longitudinal section through the two band parts after overlapping
  • FIG. 6 shows the same longitudinal section of the band parts connected firmly together by bending over of the noses
  • FIG. 7 shows a part of FIG. 6 on a larger scale
  • FIG. 8 is a partial longitudinal section through the band parts of a prior clamping band.
  • FIG. 1 denotes a wooden railway sleeper and 2 a steel band placed around the sleeper.
  • This sleeper is compressed in known manner by means of a link chain 3 laid over the steel band and tightened in the direction of the arrow.
  • the band part 2a provided with oblique noses lies on the top of the sleeper, while the other band part 2b, provided with corresponding slots, assumes the inclined position shown.
  • the two band parts are overlapped, the oblique locking noses 4 of the band part 2a passing through the slots 5 of the band part 2b, as shown in FIG. 5.
  • a securing nose 6 is provided according to the invention on the end of nose band part 2a, which securing nose is longer than the locking noses 4 and is inclined in a direction opposite to them.
  • a second securing nose 7, which is inclined in the same direction as the locking noses 4, that is to say, in the opposite direction to the securing nose 6. This second securing nose 7 is so arranged that the locking noses 4 lie between the two securing noses 6 and 7.
  • a particularly favorable effect is obtained according to the invention with the use of pressing or striking rams if both the two securing noses 6 and 7 and the locking noses 4 are bent over and pressed down on to the slot band part 2b by means of a ram or a plurality of rams with such considerable force that, as shown in FIGS. 6 and 7, considerable deformation occurs both of the nose ends 6a, 7a, 4a and of the webs 9 of the slot band part 217 pressed by these nose ends.
  • the securing nose 6 is bent over by means of a pressing or striking ram, and then bending over of the second securing nose 7 and the locking noses 4 is then effected by means of one or more rams.
  • a single ram may be used for bending over and pressing all the noses 6, 7 and 4, the pressing face of said ram being arranged parallel to the overlapped parts 2a, 2b.
  • the strength of the connection is furthermore increased by the fact that the noses 4 are bent back opposite to their original angle of bend of about 60 (FIGS. 4 and according to FIGS. 6 and 7, so that therefore the bending stresses produced in stamping out the noses are diminished.
  • the noses 4, 4a are upset, so that cold working and hence higher strength of the noses is produced.
  • these webs 9 are then pressed down with the noses 4a, 6a, 7a, so that a powerful surface pressing extending over the entire area of the overlapped band parts 2a, 2b, and hence a high frictional force is produced.
  • FIGURES 6 and 7 show that by the bending over and deformation of the locking noses 4, the nose ends 4a are so deformed that they are pressed not only by an edge but rather by a surface 13 in the width b on the webs 9. Due to this overlapping of the locking noses in the width b therefore the locking noses also effectively prevent lifting off of the band part 2b, that is to say they support the securing function of the noses 6 and 7.
  • FIGURE 7 shows that due to the powerful pressure not only the noses 4a but also the webs 9 are deformed and are partly pressed into the openings 14 of the band part 2a, which have been formed by the stamping out of the noses 4.
  • This pressing of the webs 9 into the openings 14 has the advantageous effect that, in the absence of the tensile forces Z, loosening that is to say relative displacement of these band parts in the direction D is prevented by the fact that the pressed in webs 9 are pressed against the slot edges 15 of the band part 2a, that is to say they prevent this displacement and hence support the action of the securing nose 6a.
  • slots 16 with sharp corners are provided in the band part 2b.
  • This construction means a considerable weakening of band part 2b with regard to tensile strength.
  • slots 5 are provided which are adapted to the noses 4 tapered wedge-shaped in width, that is to say they are trapezoidal, so that the tensile-stressed cross section, weakened by these slots, is reinforced.
  • the tensile strength is also increased by the fact that the corners of these trapezoidal slots, at least however the corners 18 situated on the trapezoid base 17, are rounded so that the notch effect occurring under tensile stress is thereby eliminated.
  • the securing nose 19 shown in chain lines is bent in the direction B round the sharp edges 20 of the band part 2b into the final position 19a, which results in overstressing or fracture of this securing nose.
  • the clamping band according to the invention is not only suitable for hooping wooden railway sleepers but also for binding other wood parts such as for example trunks, beams or planks and the like. Such hooping is of particular advantage when fine wood is concerned.
  • a clamping structure for an object comprising:
  • a clamping band snugly encircling said object, said band having two overlapped parts which are secured togcther, one of said parts being remote from said object and having a series of spaced-apart slots therethrough separated by web portions, the other band part being disposed between said object and said one band part and having a series of spaced-apart, substantially identical locking noses projecting toward said one band part and inclined at similar angles toward one end of said other band part, said other band part also having a securing nose projecting toward said one band part and inclined in the opposite direction with respect to said locking noses, said securing nose being longer than said locking noses, said noses being stamped out of said other band part so that openings are formed in said other band part below said noses and said openings are separated by further Web portions, said noses projecting through said slots and the free end portions thereof being bent back toward said other band part so that they eXtend substantially parallel with said one band part and overlie and snugly engage the web portions of said one band part, the adjacent edges of the web portions
  • said web portions of said one band part partially overlying and snugly engaging the web portions of said other band part and the remainder thereof overlying said openings and being displaced downwardly into said openings so that the band parts are held against lateral shifting and against relative vertical movement with respect to each other.
  • a clamping structure according to claim 2 in which the securing nose is located at one end of the series of locking noses, and including a second securing nose located at the other end of the series of locking noses, said second securing nose being longer than said locking noses and being inclined in the same direction as said locking noses and being bent down into snug engagement with a web 2.
  • a clamping structure for an object such as a wooden railroad tie, comprising:
  • a clamping band snugly encircling said object, said band having two overlapped parts which are secured together, one of said parts being remote from said object and having a series of spaced-apart slots therethrough separated by web portions, the other band part being disposed between said object and said one band part and having a series of spaced-apart substantially identical locking noses projecting toward said one band part and inclined at similar angles toward one end 'of said other band part, said other band part also having a securing nose projecting toward said one band part and inclined in the opposite direction with respect to said locking noses, said securing nose being longer than said locking noses, said noses being stamped out of said other band part so that openings are formed in said other band part below said noses and said openings are separated by further web portions, said noses projecting through said slots and the free end portions thereof being bent back toward said other band part so that they overlie and snugly engage the web portions of said one band part and extend generally parallel with said portion of said one band part.
