Definitions

  • This application concerns a construction of a special spring attachment for locking railtracks.
  • attachments which are positioned between the base of the track and one or more units which lock it to the sleeper: usually such attachments tend to feature various arched shapes with one end relating to a unit locking on to the sleeper and the other interacting directly with the base of the track.
  • the main task of the subject of this application therefore is to eliminate the above problems complained of in known types, by devising an invention which allows use of a sprung interconnection between the base of a track and a sleeper so as to permit a resultant desired value of pressure on the base of the sleeper itself , good resistence to fatigue and yielding and good elasticity.
  • a further important aim is to bring about an invention which adds to the above characteristics a main feature of being able to be disconnected from the sleeper anchoring device.
  • a further important aim is to achieve an invention which adds to the above characteristics a feature of being able to be positioned quickly and easily between the base of the track and the sleeper anchoring device.
  • a spring attachment construction especially suited for locking track to railway lines, and is characterised by the fact that it consists of a single piece having a first and a second end set roughly on the same plane, the said first and second ends being removable and positionable within countershaped housings which can be machined on a ground anchor and/or sleeper and /or support device, the said first and second ends being connected by one or more arched zones which present one or more sections which interact with the said base of a track and with the said anchoring device.
  • the structure of the spring attachment appears particularly useful for locking the base 2 of a track 3 and a sleeper 4 via the interpositioning of and anchoring device consisting of a support 5 partially sinkable into the sleeper 4 itself.
  • the structure of the spring attachment consists of round metal rod made up in one single piece, which has one first end 6 and one second end 7 set roughly on the same resting plane, these same ends having the possibility of being parallel, divergent or convergent to each other.
  • Such first and second ends also provide a terminal wall, indicated by numbers 8a and 8b, facing the same direction.
  • the spring attachment 1 presents a roughly specular shape with respect to a plane passing through the existing space between the first and second ends.
  • the construction has, opposite the terminal walls 8a and 8b, a first zone, indicated with numbers 9a and 9b, arched in the opposite direction to the adjacent end, which is set on a sloping plane to form an acute angle with respect to the resting planes of the said first and second ends.
  • the first zones 9a and 9b are connected correspondingly to a second zone, indicated with numbers 10a and 10b, slightly arched with the concave part facing the seating plane of the first and second ends, these same presenting an essentially parallel development to the first and second ends themselves.
  • the second zones 10a and 10b also lie roughly on the same parallel plane to that of the said first and second ends.
  • the lower surface of the second zone 10a is flattened 11 to interact with the base 2 of the track 3 through positioning between one or more small plates 12 preferably in a plastic material.
  • the second zones 10a and 10b appear therefore connected by a third zone, indicated with the number 13, which presents an essentially arched U-shape, whose wings 14a and 14b lie on a sloping plane with respect to the resting planes of the first and second ends.
  • the slope of such wings 14a and 14b defines, starting from the resting plane of the first and second ends, an obtuse angle, the anticlockwise rotation being a positive consideration.
  • the connecting base 15 between the wings 14a and 14b projects beyond the resting plane of the terminal walls 8a and 8b of the first and second ends, the said base 15 preferably having an arched shape.
  • Support 5 to which the spring attachment 1 can be coupled has a head 16 which has a projecting leg 17 with provision of contouring 18 for optimum sinkage correspondingly in the sleeper 4, usually made of concrete.
  • the head 16 there are machined housings one 19 and two 20, set in parallel to each other and correspondingly to the same resting plane and with a slightly higher cross section to that of first end 6 and second end 7.
  • the axial disposition of the first and second housings is such as to enable setting about parallel to the longitudinal axis of track 3, so as to set the first housing 19 adjacent to the base 2 of the same track.
  • the height of such appendage 21 with respect to the sleeper 4 is such as to allow, once the spring attachment construction is connected to support 5, preloading of second zone 10a.
  • the use of the invention is therefore as follows: once the supports 5 have been sunk in register in the sleeper 4, at an opportune distance one from the other or at a distance from the base 2 of the track 3 so as to allow the ideal positioning over the latter of the second zone 10a, the first end 6 and the second end 7 on the spring attachment 1 can then be inserted respectively in register with the first housing 19 and the second housing 20 machined on head 16.
  • a plate 12 can be positioned to advantage between the part of the second zone 10a which has a flattened part and the base 2 of the track 3.
  • the whole brings about a greater pressure on the base 2 of the track 3, with respect to known types of attachment and with rodding of equal section and through the range.
  • This improved condition wholly due to the special shape of the construction, is also determined by the fact that several of its zones are in contact with the support 5 and the track 3 and therefore also by the contrast which is created between the first and second ends of the construction with the first and second housings respectively machined on the head 16 of the support 5.
  • figure 7 illustrates a second embodiment for a spring attachment construction 301 which still consists of a first end 306 and a second end 307 set roughly on the same plane.
  • first zone 309a which has an essentially 'U' shaped conformation lying on the same plane as the said first and second ends themselves.
  • Such first zone 309a has a shape such as to be positioned between the first end 306 and the second end 307.
  • the first zone 309a is therefore connected to a third zone 313 which also has an essentially 'U' shaped conformation with the wings lying on a sloping plane of an obtuse angle with respect to the lie of the first and second ends, such angle being positive with an anticlockwise direction of rotation.
  • the base 315 of the third zone 313 has the advantage that it projects beyond the terminal walls 308a and 308b of the first and second ends.
  • first zone 310a slightly arched with the concave side facing the direction of the base of the track, which is connected to the second end 307 via a sixth zone 325 which has an essentially 'U' shaped conformation and lies roughly on the same resting plane as the first end 306 and the second end 307.
  • Figure 8 illustrates a third embodiment of a spring attachment construction 201 which is still made of a first end 206 and a second end 207 set more or less parallel to each other on roughly the same plane.
  • first zone 209a which is essentially 'U' shaped lying on the same plane as the said first and second ends themselves.
  • This first zone 209a is so shaped as to be positioned between the first end 206 and the second end 207.
  • the first zone 209a is therefore connected to a third zone 213 which is also essentially 'U' shaped with the wings lying or a sloped plane of an obtuse angle with respect to that of the first and second ends, the angle being positive with an anticlockwise rotational direction.
  • the base 215 of the third zone 213 has the advantage of projecting beyond the terminal walls 208a and 208b of the first and second ends.
  • first zone 210a slightly arched with the concave side facing the direction of the base of the track, the same being followed by a fourth zone 222 which is 'U' shaped with the wings sloping in an acute angle with respect to the resting plane of the first and second ends, which angle is achieved by a positively considered anti-clockwise turn.
  • the fourth zone 222 is therefore directly interconnected to the second end 207.
  • Figure 9 illustrates a fourth embodiment for a spring attachment construction 101 in which the first and second ends 106 and 107 are set roughly on the same plane, this construction however having a different development.
  • This fourth zone 122 has a longitudinal extension such as to come over and go beyond the second end 107; on the other side of the second end 107 the construction has a fifth zone 123 having the same U shape as the third zone 113 with the base 124 dimensioned so as to set the first end 106 adjacent to the second end 107 roughly correspondingly to the median axis of the said third zone 113.
  • a fifth embodiment of a spring attachment construction 401 which is made up of metal rod having a first end 406 and a second end 407 where the second is positioned above the first: the conformation of these same is, in section, essentially overall eliptical and of even shape, with the prerequisite housing machined in the support.
  • a first zone 409a and 409b both arched in the opposite direction to the adjacent end.
  • the first zone 409a also has an arch radius which is lower than that of first zone 409b.
  • the construction has a second zone 410a and 410b which are appropriately and advantageously arched with the concave face towards the said sleeper, and which are themselves connected to a third zone 413 which is essentially 'U' shaped with the wings lying on a roughly sloping plane with respect to the sleeper beneath of an acute angle with anti-clockwise turn considered positive.
