2 Claims. 1

This invention relates to means for fastening railroad tracks to railroad ties, and more specifically to anchoring means for rails using anchor plates, and including some resilient elements for holding the rail down from each side on'the plate.

This application is a substitute for the application of the undersigned bearing number 725,619 filed January 31, 1947 and which has become abandoned.

The object of the present invention is to give of one form of anchoring means made in accordance with the present invention, having reference to the accompanying drawing, wherein:

Figure 1 is a sectional view of a rail mounted on an anchor plate, showing spikes and holddown means made in accordance with the present invention,

Figure 2 is a plan view of one form of anchor plate which may be used as a part of this invention,

Figure 3 is a sectional view thereof taken on the line 3-3 of Figure 2,

Figure 4 is a section taken on the line 4-4 of Figure 2,

Figure 5 is a section taken on the line 5-5 of Figure 1, and

Figure 6 is a plan view of one of the resilient holddown elements.

The anchor plate I is formed, as shown, with a groove 2'for the rail 3 to rest in, and having ridges 4 along the sides of this groove, the sides 5 of the plate beyond these ridges tapering down to the edges. Strips 6 are punched out in these sides and are oifset as shown to, form clamp hooks for resilient elements 1 formed, as shown, to hold down the rail 3 from each side when mounted in place.

The plate is punched out at 8 and 9 for spikes III and II respectively to anchor both the plate and the edges of-the rail to the tie (not shown), in the usual manner. Obviously, more than one of these spikes l 0 and I I may be used on each side of the rail, ifv desired.

2 These spikes are supplemented by the resilient elements i shaped as shown so that when mounted by slipping them under the clamp hooks 6, their ends l2 will bear with a predetermined resilient pressure on the opposite sides of the rail 3.

The width of the strips 6 and their ofl'set is such that a portion of the punched slots I3 will be cleared by the free ends it of the strips 6 to provide a passage for a spike l5 to be driven there through, the lip l6 thereof overlapping the end M of the strip 6 to draw it down firmly over the element I to keep it from working out, as well as furnishing additional anchorage for the plate I The plate I is provided with small sharp ridges I! for embedding in the surface of the tie (not shown) and preventing any tendency to slip sideways thereon.

The elements I further provide holddown forces closer to the center of gravity of the rail section and are thereby more efiective in cooperating with the spikes l0 and H to lessen the shock loads thereagainst, by promptly pushing the rail back into a central position after each shock, to be in a position to lessen the succeeding shock, there being normally a slight clearance between the ridges 4 and the edges of the rail 3 in groove 2. Thus the tendency for the spikes to loosen is greatly reduced, and the rail provides a cushioning efiect on cars rolled over it.

Obvious modifications in the form and arrangements of parts may be made without departing from the spirit and scope of the present invention, as defined in the appended claims.

What is claimed, is:

1. An anchoring plate for fixing rails on ties, comprising a groove slightly wider than the base of said rails, spike holes along the edges of said groove, oflset tongues punched upwardly along the sides of said plate'to form clamp hooks, resilient means for holding down said rails over their lower flanges and formed to fit under said clamp hooks, said tongues so shaped and ofiset as to causetheir free ends to clear the ends of their corresponding slot ends suiiiciently to permit a spike to be driven through said slot, with its lip turned toward the tongue so as to overlap it and draw it firmly down over said resilient holddown means to strengthen the clamping effect.

. 2. An anchoring plate for fixing rails on ties,
