Definitions
- This operation is realized by different methods, one of which is the "packing" to which this invention is related.
- Packing consists in the introduction, with help of special shovels or injectors, of small grade ballast, or pea gravel, underneath the crossties being worked on, while the said crossties are kept in a raised position at the. desired elevation, by appropriate hoisting equipment such as lifting jacks for example.
- OMPI effects of tamping is that at each stroke, the equilibrated structure of the ballast mould around the crosstie is destroyed.
- the tamping operation must generally be completed by a vertical, vibratory compaction operation in order to rebuild a certain compaction and a certain stability of the ballast, at least in the area surrounding the crosstie, before the track is reopened to traffic.
- the present invention proposes a rail support characterized by the fact that it comprises at least one cavity-reser ⁇ voir serving as a container of small grade ballast or pea gravel to flow out of the reservoir and to be directed automatically underneath the rail support in proportion to the settlement of the underlaying ballast, under the combined effect of gravity and the amplitude of the vertical oscillations induced by the wheel sets of passing trains.
- the drawing at the appendix illustrates, as an example, one of the possible forms of the invention:
- Figure 1 is in plain view; figure 2 is the view in elevation of the section A-A through figure 1;
- figure 3 shows the section H-H of figure 1 in elevation; figure 4 shows the bottom face; figure 5 and 6 show the cross-sections B-B and C-C of fig. 2; figure 7 and 8 show the cross-sections D-D and E-E of fig. 3. Description of the Preferred Embodiments
- the rail support in this example is a concrete tie (1) with two rails
- This concrete tie (1) includes two cavities (4) opening on the surface of said tie (1), placed as close to the rails (2) and (3) as possible without interfering with their means of fastening.
- the bottom (5) of these two cavities is inclined from the most distant face (6) toward the face closest (7) to the rail.
- To this face (7) are connected two lateral conduits (8) and (8') . the orientation of which is parallel to that of the longitudinal axis of the tie (1), and the faces of which are biased toward the bottom face (9) with the openings
- the openings (10) and (10') are centered under the rails (2) and (3) and spaced transversally in such a proportion that the distance between two openings corresponds approximatively to two times the distance which separates them from the lateral faces (11) and (12) of the tie (1).
- the dimensions of the tie (1) are of course established with regard to the continuity of mechanical resistance through the cavities (4) and their conduits (8) and (8').
- the width of the bottom face (9) of the tie (1) is increased by the sum of the widths of the
- the "packing" operation of a railroad track built on crossties such as described above, is extremely simple. It is sufficient to fill the cavities (4) with small grade ballast or pea gravel. As soon as the track settlement becomes irregular, the packing process is initiated automatically by the oscillations induced by the wheel sets in motion, as mentioned before. In fact, as symbolized by the small arrows on figure 6, the particles of the small grade ballast or pea gravel contained in the cavity (4), by their weight have the tendency to flow underneath the bottom face (9) of the crosstie (1) onto the underlaying ballast.
- the outflow of small grade ballast or pea gravel is facilitated by the conical shape of the conduits (8) and (8') which, combined with the effect of the vertical oscillations of the tie, accelerates the outflow and hinders the backing or lock-up of the particles in the said conduits; but this particularity is not indispensable.
- the transverse symmetrical partitioning of the openings (10) and (10') on the bottom face (9) of the crosstie produces an equal distribution of the particles on either side of the opening if suc distribution is preferred; but this particularity is not indispensable either.
- the rail support fully pervades the objective striven for, given the fact that it provides all advantages of the so-called "packing" method in an economical, automatic mode, eliminating all of the time-consuming, expensive operations of the method which have been described above, and does so by recurring to the very same phenomenon which causes the settlement, to automatically correct and compensate its effects.
- the replenishing of the cavities with small grade ballast or pea gravel is the only exterior intervention, and the replenishing lends iself easily to mechan- isation, because the cavities can be designed to be very accessible, such as in the example shown above. Design changes can be realized without altering the applicability of the invention.
- a single cavity-reservoir for example, centered half-way between the two rails, can be connected with the bottom face of the tie underneath
- the rails by an unspecified number of conduits, the openings of these conduits leading to the bottom of the rail support being of variable length or width, according to the desired effect and the required size of the bearing surface.
- a removable cover can be installed to close each cavity.
- the openings can be placed in the upper part of the ends, or in the vertical faces of the crosstie sides.
- the concrete tie (1) given as an example of possible execution of the rail support is not limitative, and the invention is applicable to all other types of crossties, as well as to large surface slab sections and pads, provided these various elements function as rail supports and transmit and distribute dynamic loads.
- the cavity-reservoir may be attached to one or the other upper part of these crosssties.

Abstract
Une nouvelle traverse de chemin de fer (1) comprend une cavite (4) formant reservoir contenant du ballast de granulometrie fine ou du gravier fin, qui est automatiquement depose sous la traverse (1) en fonction du tassement du ballast sous-jacent. Le complement de ballast de granulometrie fine ou de gravier se depose automatiquement sous l'effet combine de la gravite et de l'oscillation d'amplitude verticale produite par les roues des trains qui passent.
