The lugs and ribs, preferably are all pressed out simultaneously or irst one lug and one rib, both in one half of the tie, are pressed out simultaneously and then the tie is reversed in position to bring the other half near the pressing tools and then the other lug and the other rib are pressed out simultaneously.
BRIEF DESCRIPTION OF THE DRAWING
An example in accordance with the invention is described below with reference to the accompanying drawing, in which:-Figure 1 shows an end view of part of a railwayrail-and-fastening assembly, and Figure 2 shows a plan view of the same part of the assembly as Figure 1, and Figure 3 shows an end view of the complete assembly.
DETAILED DESCRIPTION OF THE DRAWING
Referring to Figures 1 and 2, the illustrated part of the assembly includes a rail tie 1 made of rolled sheet steel and in the conventional shape of a flat-bottomed trough inverted.
In each half of the length of the tie there is a projection in the form of a lug 2 which has been pressed out of the material of the top 3 of the tie (i.e. the base of the trough~. There is also in each half of the length of the tie a portion in the form of a rib 4 which has been pressed out of the material of the top of the tie. Each rib forms a horizontal passageway 5 closed at the top, open at both ends, and perpendicular to the length of the tie.
On each half of the length of the tie rests a rail 6, having a flange 7 at its bottom which stands on a support surface on the tie, the lug 2 in that half of the ,, ~.~1'7~
tie having~ proceeding from i-ts roo-t -to its -tip, firstly a par-t 2A ex-tending up -the edge o~ one side of the flange at an angle of more than 60 to the horizontal and then a part 2B which lies above and close to that side of the flange and extends upwardly at an angle of less than 30 to the horizontal. The passageway 5 in that half of the sleeper is beside the edge of -the flange on the other side of the flange and is parallel to the rail.
Two rail clips 8 are used -to hold -the rails to the tie, each having been made by bending a steel rod of circular cross-section, a substantially straight leg 8A of each clip being in a respective one of the passageways 5, a portion 8B of each clip bearing down-wardly on the flange of a respective one of the rails and a portion 8C of each clip bearing downwardly on a respective fixed surface 9 which, as seen from -the associated rail, is beyond the associated passageway 5, the surface 9 being part of the top of the sleeper.
The illustrated lug 2 is integral with the top of the tie and joined to it on one side of the a~ove-mentioned support surface and the illustrated rib 4 is on the opposite side of the support surface and is like--wise integral with the top of the tie. It projects higher than said support surface and locates that edge of the illustrated rail flange which is remote from the projection 2 and from the other railO
The illustrated tie can be used with a rail having a narrower flange, the left-hand edge of which, in contrast to what is shown in -the drawing, will not 80~
extend to the junction between the parts 2A and 2B of the projection 2.
Figure 3 shows the ends A and B of the tie and the two rails, two lugs, two ribs and two clips, in the one case with the prefix 1 ana in the other case with the pre-iX 2 before the reference numerals used in Figures 1 and 2.It is to be noted that the lugs 12 and 22 are between the ribs 14 and 24. They prevent the rails tipping so that the distance between the tops o~ the rails increases, i.e. the gauge of the railway track increases.

The lugs and ribs, preferably are all pressed out simultaneously or irst one lug and one rib, both in one half of the tie, are pressed out simultaneously and then the tie is reversed in position to bring the other half near the pressing tools and then the other lug and the other rib are pressed out simultaneously.
BRIEF DESCRIPTION OF THE DRAWING
An example in accordance with the invention is described below with reference to the accompanying drawing, in which:-Figure 1 shows an end view of part of a railwayrail-and-fastening assembly, and Figure 2 shows a plan view of the same part of the assembly as Figure 1, and Figure 3 shows an end view of the complete assembly.
DETAILED DESCRIPTION OF THE DRAWING
Referring to Figures 1 and 2, the illustrated part of the assembly includes a rail tie 1 made of rolled sheet steel and in the conventional shape of a flat-bottomed trough inverted.
In each half of the length of the tie there is a projection in the form of a lug 2 which has been pressed out of the material of the top 3 of the tie (i.e. the base of the trough~. There is also in each half of the length of the tie a portion in the form of a rib 4 which has been pressed out of the material of the top of the tie. Each rib forms a horizontal passageway 5 closed at the top, open at both ends, and perpendicular to the length of the tie.
On each half of the length of the tie rests a rail 6, having a flange 7 at its bottom which stands on a support surface on the tie, the lug 2 in that half of the ,, ~.~1'7~
tie having~ proceeding from i-ts roo-t -to its -tip, firstly a par-t 2A ex-tending up -the edge o~ one side of the flange at an angle of more than 60 to the horizontal and then a part 2B which lies above and close to that side of the flange and extends upwardly at an angle of less than 30 to the horizontal. The passageway 5 in that half of the sleeper is beside the edge of -the flange on the other side of the flange and is parallel to the rail.
Two rail clips 8 are used -to hold -the rails to the tie, each having been made by bending a steel rod of circular cross-section, a substantially straight leg 8A of each clip being in a respective one of the passageways 5, a portion 8B of each clip bearing down-wardly on the flange of a respective one of the rails and a portion 8C of each clip bearing downwardly on a respective fixed surface 9 which, as seen from -the associated rail, is beyond the associated passageway 5, the surface 9 being part of the top of the sleeper.
The illustrated lug 2 is integral with the top of the tie and joined to it on one side of the a~ove-mentioned support surface and the illustrated rib 4 is on the opposite side of the support surface and is like--wise integral with the top of the tie. It projects higher than said support surface and locates that edge of the illustrated rail flange which is remote from the projection 2 and from the other railO
The illustrated tie can be used with a rail having a narrower flange, the left-hand edge of which, in contrast to what is shown in -the drawing, will not 80~
extend to the junction between the parts 2A and 2B of the projection 2.
Figure 3 shows the ends A and B of the tie and the two rails, two lugs, two ribs and two clips, in the one case with the prefix 1 ana in the other case with the pre-iX 2 before the reference numerals used in Figures 1 and 2.It is to be noted that the lugs 12 and 22 are between the ribs 14 and 24. They prevent the rails tipping so that the distance between the tops o~ the rails increases, i.e. the gauge of the railway track increases.
