Abstract

Apparatus, devices, assemblies, systems and methods of using w spring clips over spikes for holding railroad tie spikes down to wood and concrete railroad ties and hold the spike heads to the rails. A first embodiment can use rail tie plates with box holders for holding end portions of a w shaped spring steel clip to press against cap heads of railroad tie spikes. A second embodiment can use a rail tie plates with vertical supports for horizontal bars over heads of railroad tie spikes. A third embodiment can use rail tie plates with vertical studs and upper threaded ends with flat plates attached by nuts over heads of rail road tie spikes, and with cotter pins locking the nuts in place. Additional embodiments include metal structures fastened, welded and/or forged to tie plates for allowing w shaped spring clips with mid portions that hold down heads on spikes to prevent the spikes from coming out.

Claims (46)

1. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure attached to the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the portion that covers the head portion of a railroad spike includes:

a plurality of w shaped spring clips.

2. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure attached to the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the at least one metal structure is welded to the upper surface of the tie plate.

3. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure attached to the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the at least one metal structure includes a box holder with an opening.

4. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure attached to the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the at least one metal structure includes metal structure with horizontal channel opening.

5. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure extending upward from sides of the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the portion that covers the head portion of a railroad spike includes:

a plurality of w shaped spring clips.

6. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure extending upward from sides of the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the at least one metal structure includes: a pair of metal brackets.

7. The railroad spike retention system of claim 6 , further comprising:

an elongated rod extending between the pair of metal brackets.

8. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having an top surface facing upward, and a bottom surface facing downward; and

at least one metal structure extending upward from sides of the upper surface of the tie plate having a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out, wherein the at least one metal structure includes: a pair of metal studs.

9. The railroad spike retention system of claim 8 , further comprising:

a metal plate extending between the pair of metal studs.

10. A railroad spike retention system for retaining spikes to rail ties, comprising:

a metal tie plate with a plurality of through-holes for railroad spikes, the metal tie plate having a top surface facing upward, and a bottom surface facing downward;

inverted L shape brackets attached to the upper surface of the tie plate; and

a member with a portion that covers a head portion of each railroad spike for preventing each railroad spike from coming out.

11. The railroad spike retention system of claim 10 , wherein the member with the portion that covers the head portion of a railroad spike includes:

a plurality of w shaped spring clips.

12. The railroad spike retention system of claim 10 , further comprising:

a horizontal plate attaching the inverted L shape brackets to the top surface of the tie plate.

13. The railroad spike retention system of claim 12 , wherein the horizontal plate is welded to the top surface of the tie plate.

14. The railroad spike retention system of claim 12 , wherein the horizontal plate is forged to the top surface of the tie plate.

15. The railroad spike retention system of claim 12 , further comprising:

studs extending upward from the top surface of the tie plate having upper threaded ends for attaching the horizontal plate to the tie plate.

16. The railroad spike retention system of claim 12 , further comprising:

studs extending upward from the top surface of the tie plate, the studs having upper ends forged to the horizontal plate.

17. A railroad spike retention system for retaining spikes to rail ties, comprising:

a base plate fixedly attached to a rail road tie plate; and

at least one w shaped spring clip, where said baseplate holds and locks said w shaped spring Clip in place, and a portion of the w shaped spring clip extends over a top portion of a railroad spike head.

18. The railroad spike retention system of claim 17 , wherein the at least one w shaped spring clip includes:

a plurality of w shaped spring clips.
