TIE PLATE.

Application filed 4 m 24, 1928. Serial No. 272,522.

This invention relates to rail fastenings, and embodies an improved tie-plate and spike for attaching a rail to a tie.

The object of the invention is to provide 5 an improved anti-creeping plate and fastening, which will prevent movement of the plate with respect to the tie and also prevent movement of the rail with respect to the plate.

u A further object of the invention is to provide an improved tie plate having the ad vantages referred to and which maybe produced at a relatively low cost.

These and other objects are effected by 5 providing a plate having a lip which overlaps one edge of the rail base, and by providing a wedge shaped lock engaging the other edge of the railbase, fastened by a spike which when driven through the plate and into 3' the tie will hold the lock which presses against the opposite edge of the rail base and so forces the base tightly against the lip whereby creeping is prevented; and no special rail structure is necessary.

One form of the invent-ion is illustrated in the accompanying drawings in which Fig. 1 is a perspective view of the device in use. Fig. 2 a top plan of the tie plate and rail base. Fig. 3 is a section on the line 3--3 of Fig. 2,

In the drawings, the rail is indicated at 6, of the usual form. The tie-plate is indicated at 7 and its top surface is preferably tilted at a slight angle where the rail seats upon it.

The bottom of the plate has a series of cross ribs 8 with intervening depressions 9, the

ribs being raised from the bottom face of the plate so as to bite into the tie and prevent the plate shifting.

Atthe side of the tie-plate opposite the lip an abutment 13 is provided, projecting upwardly from the surface of the plate, and

' preferably cast integral therewith. The in ner face of this abutment or lug, that is the face 14 next to the rail base, is at an angle to place against accidental removal.

the line of the rail, and has at the top a i 15 projecting inwardly. A Wedge 16 is driven between this abutment and the edge.

of the rail base, and this wedge has on its inrail base is engaged. The top face of the ner side a groove 17 'n which the edge of the plate is stepped down or recessed slightly, as indicated at 18, to permit the inner edge of the wedge to engage under the edge of the rail;

base. The smaller end of the wedge is formed with an offset or shoulder 19, andafter the wedge is driven in a spike 20 is driven behind this shoulder, through a prepared spike hole in the plate, and so locks the wedge in Thespike must first be removed before the wedge can be driven out. The ordinary spike may be. driven through the spike hole 21.

The wedge by its action jams the rail base against the lip 10 and looks it against creep ing and so binds the rail and tie-plate together as to form a rigid fastening which cannot become loose under any ordinaryconditions.

The lateral thrust against the rail base, due to the wedge, is superior in its holding effect to the action of ordinary spikes which often become loose in the tie and exert nosuch thereon adapted to overlap one edge ofa rail base, and having an upstanding abutment opposite the lip, a wedge fitting between said abutment and the opposite edge of the rail base and adapted to clamp the saidbase against said lip, thesmallend of the wedge projecting beyond said abutment and having a shoulder, and a spike driven through the plate, between and in contact with said shoulder and the abutment, to prevent withdrawal of the wedge.
