HEIGHT ADJUSTABLE CONNECTION OF A RAIL. To A TIE Filed June 9, 1953 2 Sheets-Sheet 2 INVENTOR. Graral KR/ijflE/tQA/W HEIGHT ADJUSTABLE CONNECTION OF A RAIL TO A TIE Gerard Krabbendam, Zeist, Netherlands Application June 9, 1953, Serial No. 360,553
2 Claims. (Cl. 238-281) The invention relates to a connection adjustable in the height of a rail on a bearing member, such as a crosstie, by means of a wedge arranged between the bearing member and the rail. These wedges serve to adjust the rail accurately in the height, so that it is not necessary any more to introduce material under the sleeper. The unequal depression of the ties is a result of the unequal formation of the ballast-bed. In consequence of the compression of this ballast-bed a rather hard under-layer is obtained, which would be disturbed when new material is brought underneath. If now by the unequal depression a tie comes to lie loose, it is only necessary to strike against the Wedge, in order to press the tie again firmly on the ballast-bed. These wedges have the drawback that they can easily be loosened by vibration because they are clamped on the inclined wedge face, giving rise to a lateral component, which loosens the wedge. It has been endeavoured to remove this objection by using a stepped member instead of a wedge, but in so doing an accurate control is not possible, since one has to depend on the height of the steps.
The purpose of the invention is to remove these drawbacks and to provide a wedge which is not released by vibration during the trafiic and in which it is possible to adjust the rail at any desired level.
According to the invention this is attained in that the wedge can be fixed in any desired position by clamping at least a part of the side faces. According to the invention it is possible as well to provide the wedge along the side faces with an inclined surface, arotmd which a claw of the connecting device of the rail engages, which claw again provides the lateral clamping. In this case the claw can be provided with one or more teeth engaging teeth provided along the side face of the wedge.
The invention will be elucidated by the drawing by means of two embodiments.
Fig. 1 is a first embodiment in cross-section of a connection of a rail according to the invention;
Fig. 2 is a plan view of same;
Fig. 3 is a side view in perspective of a second embodiment of a connection according to the invention.
The connection has a base plate 1 on the tie 2. The base plate 1 possesses four upright parts 3, 4, and 6; the parts 3 and 4 are situated at one side of the rail 7 and the parts 5 and 6 at the other side of same. These protruding parts fix the plate of the foot of the rail 7 in the horizontal plane and at the same time form rectangular to same the guides for the wedge 8. The wedge has the angle which at horizontal track the upper face of the head of the rail makes with a horizontal plane.
By striking the wedge further underneath the rail a ited States Patent 0 ice loose cross-tie becomes portable without being dug out at the lower side and applying an excess of material. The connection of the rail 7 is furthermore carried out by two clamping plates 9 in which a recess is provided and which at the one side bear on the foot of the rail and at the other side directly or indirectly on the wedge. These clamping plates are pressed down by means of two clamping bolts 10 which are screwed into bridgepieces 11, the bolts bearing in the recesses of the clamping plates. The bridge-pieces 11 are connected with the upright parts 3, 4, 5 and 6.
It desired, these parts are arranged interchangeably. The wedge 8 is locked against receding by screwing-on a bolt 12 which passes through two slits in wings of the parts 5 and 6. The wings are so connected that they are pressed toward the wedge. In this way the wedge is locked at the side face by friction of the wings against the parallel side faces of the wedge.
In Fig. 3 the bolts 10 are arranged in loose bridgepieces 14, which with their ends extend into apertures of the upright parts 13. These parts may be U-profiles which are welded to the plate 1 or in the case that concrete cross-ties are applied, are embedded in the concrete. The clamping plates 15 are provided with a U-like part which clamps a chamfiered side 16 of the wedge 8.
The inclination of this chamfered face 6 is such that there is a question of a lateral clamping. Also these U-like parts having the shape of a claw may be provided with teeth engaging indentations 17, along side face of the wedge. Now it is not necessary any more to apply separate wings, since with this embodiment the clamping plates provide for the lateral clamping.
I claim:
1. Height adjustable connection of a rail to a bearing member, comprising: a wedge member located between the bearing member and the rail, said wedge member having longitudinally extending upper and lower surfaces inclined relative to each other and having a pair of longitudinally extending side surfaces, portions of said upper and lower surfaces of the Wedge member being engaged with said rail and said bearing member respectively, and clamping means securing the wedge member in its position, said clamping means being engaged with portions of said longitudinally extending side surfaces of said wedge member.
2. In a height adjustable connection of a rail to a bearing member as claimed in claim 1, each of said side surfaces of the wedge member being chamfered at its upper portion so as to form longitudinally extending chamfered surfaces, and said clamping means being in engagement with portions of said chamfered surfaces.
