This invention relates to railroad tie spikes, and in particular to apparatus, devices, assemblies, systems and methods of using clips over spikes for holding railroad tie spikes down to wood and concrete railroad ties and hold the spike heads to the rails.
Trains run on rails supported on cross ties formed of wood. The rails are commonly made of a steel, and have mounting flanges. The mounting flanges are adapted to rest on metallic bearing plates, generally referred to as tie plates or fishplates. The fishplates rest on the wooden ties, and spikes are used for securing rails to wooden ties. Spikes are often inserted in an opening or cavity in the fishplate and the spike shank is driven into the tie. The head of the spike is generally adapted to engage with the flange of the rail, thereby securing the rail to the tie. Alternatively, the tie plates or fish plates are equipped with a metal clip or boss that engages to the flange of the rail, and the head of the spike is adapted to engage with the fishplate to secure the rail to the tie. See for example, U.S. Pat. No. 457,584 to Goldie; U.S. Pat. No. 4,141,500 to Gragnani; U.S. Pat. No. 4,350,291 to Dobson; U.S. Pat. No. 4,461,422 to Harkus; U.S. Pat.

In this preferred embodiment, the plurality of spaced apart left metal structures 640 can include a first left metal structure 642 with side through-hole 643, second left metal structure 644 with side through-hole 645, third left metal structure 646 with side through-hole 647, and fourth left metal structure 648 with side through-hole 649. Each of the left metal structures 640 having angled channel openings substantially parallel with each other. The angle channel openings of each of the plurality of spaced apart left metal structures 640 having longitudinal axes substantially perpendicular to the first elongated ridge 612.
The w shaped spring clip 680 can include a first leg 682, with side through-hole 683, a bent mid portion 684, and a second leg 686 with side through-hole 687.
The installer can insert the legs 682, 686 of one spring clip 680 into the angled channel openings of a pair of metal structures 642, 644. Another spring clip 680 can have its' legs 682, 686 into the angled channel openings of a second pair of metal structures 646, 648.
The spring clips 680 can be locked to respective metal structures 642, 644 by one of the cotter pins 670 passing through a side through-hole 543 in a first left metal structure 542 and through a side through-hole 583 in the first leg 528 of the spring clip 580. Another one of the cotter pins 570 can be passed through a side through-hole 645 in a second left metal structure 644 and through a side through-hole 687 in a second leg 686 of the spring clip 680. Another spring clip 680 can be locked to a second pair of metal structures 646 and 648 with another pair of cotter pins 570 passing through adjacent through-holes 647683 and adjacent through-holes 649, 687.
A plurality of spaced apart right metal structures 660 can be fixed to the tie plate 610 adjacent to the second elongated ridge 616. The plurality of right metal structures 660 can be welded and/or forged to the metal tie plate 610.
In this preferred embodiment, the plurality of spaced apart right metal structures 660 can include a first right metal structure 662 with side through-hole 663, second right metal structure 664 with side through-hole 665, third right metal structure 666 with side through-hole 667, and fourth left metal structure 668 with side through-hole 669. Each of the right metal structures 660 having angled channel openings substantially parallel with each other. The angled channel openings of each of the plurality of spaced apart right metal structures 660 having longitudinal axes, substantially perpendicular to the second elongated ridge 616. Each of the plurality of right metal structures 660 can include a first right metal structure 662 with side through-hole 663, second right metal structure 664 with side through-hole 665, third right metal structure 666 with side through-hole 667 and fourth right metal structure 668 with side through-hole 669.
Another set of spring clips 680 can be locked into the angled channel openings of the plurality of right metal structures 660 with additional cotter pins 670 in a similar manner to the cotter pins 670 used with the left plurality of metal structures 640.
The bent midportions 684 of each spring clip 680 is pushed over a portion of each head of the spikes 602, 604 retaining the spikes 602, 604 in place.
Although the embodiments show the use of pins, such as cotter pins being used, other types of fasteners, such as but not limited to screws with or without nuts and washers, and the like can also be used.
While the above embodiments describe attaching base plates to tie plates, and attaching metal brackets and metal parts to metal tie plates by welding, other types of attachment techniques can be used, such as but not limited to mechanical attachments, and any other way of forming attachments, such as but not limited to forging, and the like.
The w spring clips can further be attached to mechanical structures shown and described in U.S. Pat. No. 5,520,330 to Brown et al., which is incorporated by reference.
While the embodiments show and describe retaining railroad spikes to rail ties, the embodiments can be used to retain railroad screw shaped spikes to rail ties.
Although fasteners, such as nuts and washers are shown and described, other types of fasteners can be used, such as but not limited to locking washers, and the like. Parts can be attached together by welding, forging, heating with and without hydraulic presses and the like.
While some embodiments reference using upwardly protruding studs with threaded ends for nuts to attach metal plates to the metal tie plate, other techniques can be used to fasten metal parts together.
For example, an upwardly protruding rod without a threaded end can be used where the rod is heated and a hydraulic press compresses the upper end forming a head attaching a horizontal plate to the tie plate. See for example,
The upwardly protruding rod can initially be a stud with a head on one end that is pushed up through holes in the tie plate, and the head of the stud can be welded to the undersurface of the tie plate. Afterward a horizontal plate can be attached to the tie plate as previously described.
This new railroad tie plate invention is very important to the safety of the railroad industry. Currently rail spikes are constantly coming out and with the constant pounding of the freight trains no method of keeping them in exists.
Lag screws are also prone to coming loose and this causes the rail gauge too separate causing train derailments.
A Global rail infrastructure company sees the value in this invention.
It could save countless lives and many millions of dollars in damage caused by train derailments.
