- said tooth means on said second clip being positioned outwardly of said T-shaped head portion of said second clip bolt to maintain said T-shaped head portion of said second clip bolt in said second slot and said shank portion in said third opening;
- and a nut means on the upper end of said second clip bolt for maintaining said second clip thereon.
- 2. The bolted rail fastening system of claim 1 wherein said tooth means on said first clip protrudes inwardly from the inner end of said inner end portion and wherein said tooth means of said second clip protrudes outwardly from the lower end of said outer end portion thereof.
- 3. The bolted rail fastening system of claim 1, wherein said cross-tie is oriented generally perpendicularly to said rail, and wherein said first clip is offset in one direction from the longitudinal center of said cross-tie and wherein said second clip is offset in an opposite direction from the longitudinal center of said cross-tie, to produce a staggered orientation of the clips with the rail.
- 4. The bolted rail fastening system of claim 3, further comprising:
- a second rail having a base flange, supported on said cross-tie spaced-apart and parallel to said first rail;
- a second tie plate having an upper surface, and a bottom surface positioned on the cross-tie;
- said second tie plate having a central recessed area formed in the upper surface thereof for receiving the base flange of the second rail therein;
- said recessed area being defined by a longitudinally extending fourth pair of shoulders on said second tie plate, said second tie plate having a gauge side positioned inwardly of said recessed area and a field side positioned outwardly of said recessed area;
- said second tie plate having at least one opening formed therein adjacent each of the gauge and field sides thereof for receiving a fastening means extending downwardly therethrough into the cross-tie to secure said second tie plate to the cross-tie;
- said tie plate having a third generally rectangular-shaped opening formed therein extending downwardly therethrough between said recessed area and said gauge side, said third rectangular-shaped opening having its longitudinal axis parallel to the longitudinal axis of the second rail;
- said second tie plate having a third slot formed beneath its upper surface which communicates with the lower portion of said third rectangular-shaped opening and which extends therefrom towards said recessed area;
- said second tie plate having a fourth opening formed therein extending downwardly therethrough, from the upper surface thereof, adjacent said recessed area which communicates with said third slot to define a fifth pair of shoulders therebetween;
- a third clip bolt having a generally T-shaped head positioned in said third slot and a shank portion extending upwardly through said fourth opening, said T-shaped head being prevented from upward vertical movement by said fifth pair of shoulders;
- a third clip positioned on said third clip bolt and comprising an upper end portion having inner and outer ends, an outer end portion extending downwardly from the outer end of said upper end portion for engagement with the base flange of the second rail, an inner end portion extending downwardly from the inner end of said upper end portion, and a tooth means extending downwardly from the lower end of said inner end portion of said third clip into said third rectangular-shaped opening, said tooth means having a length substantially equal to the length of said third rectangular-shaped opening, said inner end portion having a length greater than said third rectangular-shaped opening to form wing portions in engagement with said second tie plate at opposite ends of said third rectangular-shaped opening;
- said tooth means being positioned inwardly of said T-shaped head portion of said third clip bolt to maintain said T-shaped head portion of said third clip bolt in said third slot and said shank portion in said fourth opening;
- a nut means on the upper end of said third clip bolt for maintaining said third clip thereon;
- said second tie plate having a fourth generally rectangular-shaped opening extending downwardly therethrough between said recessed area and said field side, said fourth rectangular-shaped opening having its longitudinal axis parallel to the longitudinal axis of the second rail;
- said second tie plate having a fourth slot formed beneath its upper surface which communicates with the lower portion of said fourth rectangular-shaped opening and which extends therefrom towards said recessed area;
- said second tie plate having a fifth opening formed therein extending downwardly therethrough, from the upper surface thereof which communicates with said fourth slot, to define a sixth pair of shoulders therebetween;
- a fourth clip bolt having a generally T-shaped head positioned in said fourth slot and a shank portion extending upwardly through said fifth opening, said T-shaped head of said fourth clip bolt being prevented from upward vertical movement by said pair of shoulders;
- a fourth clip positioned on said fourth clip bolt and comprising an upper end portion having inner and outer ends, an inner end portion extending downwardly from the inner end of said upper end portion of said fourth clip for engagement with the base flange of the second rail, an outer end portion extending downwardly from the outer end of said upper end portion, and a tooth means extending downwardly from the lower end of said outer end portion of said fourth clip into said fourth rectangular-shaped opening, said tooth means having a length substantially equal to the length of said fourth rectangular-shaped opening, said outer end portion having a length greater than said fourth rectangular-shaped opening to form wing portions in engagement with said second tie plate at opposite ends of said fourth rectangular-shaped opening;
- said tooth means on said second clip being positioned outwardly of said T-shaped head portion of said fourth clip bolt to maintain said T-shaped head portion of said fourth clip bolt in said fourth slot and said shank portion in said
- and a nut means on the upper end of said fourth clip bolt for maintaining said fourth clip thereon;
- said third clip being offset from the longitudinal center of said cross-tie and parallel to said first clip;
- said fourth clip being offset from the longitudinal center of the cross-tie and parallel to said second clip,
- whereby the third and fourth clips are staggered in reverse of said first and second clips on said cross-tie.
