T 0 all whom it may concern:

Be it known that}. l'VAIPEN M. a citizen of the United dent of Chicago. in the count State of Illinois having invents new anduset'ul Improvements in Tie Plates. do herebv declare that .l

as following is a full, clear, and exact desmiption of the same.

,My invention relates torailway tie plates and its object is to provide new and improved means for utilizing the same plates for rails having bases or different sizes.

The invention consists of the matters hereinafter described and then pointed out in the claims.

In the drawings, Fig. l is a cross-sectional view of a plate and an associated rail hav ing a relatively small base with the spikes in the outer ends of the spikediv and the, spike-plugs between the spikes and rail-base, illustrating a practical embodiment ot' my invention Fig. 2 is a similar View with a rail having a relatively wider and thicker base;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 1; and

Fig. 4c is a detail sectional view on the line H of Fig. 2.

In the drawings the reference letter represents the head, B the base and G the web of the rail.

The tie plate consists of the bod;.' 5 prc vided near one side with the spike-holes ti. and near its other side with spike holes 7.. Both sets of spike holes are elongated in the cross-sectional line of the plate; the distance between the inner ends of the opposite sets of holes is substantially the width of the narrowest rail-base B with which the plates are to be associated. The spikes S for the holes pass through their outer portions, and spike-plugs 9 of various widths according to the width of the rail base, are inserted be tween the spikes and the rail-base to hold the rail in position on the plate; the distance between the outer ends 01"? the opposite sets of holes is equal to the width overall of the widest rail base and the opposite plugs and spikes.

The spike-plugs 9 are individual pieces of metal adapted to be inserted in the otherwise unoccupied portions of the elongated spike holes and are of sufficient cross-sectional area to fill up the gap that otherwise would exist n filed March 5, 1921, Serial No. 4-93)? Renewed. tiarch 10, 1924.

between the ra l-base and spike, being made of different widths in this respect so that such gaps of varying widths may be filled according as the size of the rail-base ma vary. For illustr tion, Fig. 1 shows a relatively small rail whose base is substantially as wide as the distance between the inner ends or" the opposite spike holes, and 2 shows a relatively wider rail-base that may extend more or less over the inner ends of one or both sets of the holes, and the plugs in the holes of Fig. 1 are wider than the plugs in the holes of Fig. 2; in other words, wider rail-bases extend more or loss over the inner ends of the holes. and the plugs are correspondingly proportioned in width to fill the gaps.

The spike-plugs interlock with the plate. The plugs are inserted into the spike-holes from below, and are provided along their lateral edges at their lower ends with flanges 10, which interlock the plugs and plate and preferably fit in correspondingly countersunk seats 11 in the lateral walls of the lower ends of the spike-holes. The plugs are provided at their upper ends with inwardly directed wings 12, which overlie the rail-base when the spikes are driven to place into the tie 13. The plugs interlock the rail and base when the parts are assembled; the rail cannot move up or tilt on the plate even it the spikes are loosened, because it the spikes become loose or pump under the strains to which they are subjected by the trai'iic on the rail the plug remains in its original and intended position as it is locked under the plate, and the rail remains in its corresponding position on the plate .as it is interlocked between the plug and plate. In short, the plugs interlock with the plates by their flanges co-operating with the lower ends of the hole and the rails are locked to the plates by the wings of the plugs, these parts thus forming a unitary structure, which can be employed on the ordinary ties and without any preliminary preparation or cutting of the latter, and any tendency of the spikes to pump or work loose does not affect this unitary relation as the flanges retain. the plugs in position they prevent them from rising under the stress or friction of a pumping spike and the co-operation of the flanges with their seats prevents the plug from turning when the spike is loos in using the plugs they are placed in the sectional area of the plate.

' spike-holes and the rail base is positioned.

on theplate; and the spikes are then driven into'the'underlying tie 13 and crowd the plugs against the rail-base and force their wings upon 'its upper face. 'By arranging the elongated holes so that the distance between the inner ends of the opposite sets corresponds to the minimum width of railbase and the distance between their outer ends exceeds the maximum width of railbase sufficiently to insert the plugs and spikes the same plates maybe used for rails having wide or narrow bases, and in either case both sides of the rail-base are interlocked with the plate by the plugs so that the effective surface or hearing of the rail on the tie to resist its tilting in either direction is expanded to equal the entire cross- Also, the rail is held on both sides against creeping in either direction as any longitudinal movement of the rail tends to turn the plug and so causes one or the other of its corners according tothe direction of the creep of the rail to wedge against the edge of the rail-base more or less to resist this movement. If desired the face of the plugs bearing on the rail-base may be provided with aconcavity 1% .to present anti-creeping edges 15 to the rail-base, one of which will bite into the rail-base more or less according to the direction of the tendency of the rails to creep. The edges 15 may be case-hardened to a high-temper to form cutting surfaces. The lower surfaces of the plugs may be provided with ribs 16 to engage the tie andresist the creeping tendency of the rail.

The plugs are made to co-operate with rail-bases of different thicknesses or heights by varying the distance between the lower face of .the wing and the upper faces of the flanges. Thus, as shown in Fig. l with a relatively thin rail-base the flanges of the plugs are set nearer the wing, and as shown in Fig. 2 with a relatively thicker rail base the flanges are set farther away from the wing.
