RAIL AND RAIL-TIE PLATE.

Specification of Letters Patent.

Application filed April 6, 1911.

Patented Oct. 3, 1911. Serial No. 619,429.

To all whom it may concerns Be it known that I,\HARRY E. HAIGHT, citizen of the United States, residing at Marshfield, in the county of Wood and State of Wisconsin, have invented certain new and useful Improvements in Rails and Rail- Tie' Plates, of which' the following is a specification.

This invention has relation to rail tie plates, and has for its object to provide a plate of simple structure adapted to receive the base flange of the rail .and hold the same against tilting or ca-nting, and at he same time is provided with means for engaging the under face of the base flange of the rail to prevent the rail and track from creeping.

On all heavy trunk lines where the traffic on the rails is in one direction, considerable difliculty' is experienced in keeping the track. from creeping in the direction with the traflic, or in the direction in which the rolling stock movesover'the track, and it is the aim of the present invention to provide means for effectually supporting the rail and at the same time eliminating the creeping of the track and the disadvantages incident thereto.

With these objects in view, the structure includes a tie plate having a roughened under surface adapted to bear against the upper surface of the tie, said plate being provided with a flange adapted to bear upon the upper surface of the base flange of the rail to prevent the same from tilting or canting. The said plate is also provided with serrations which extend transversely with relation to the long dimensions of the rail and at the point where the rail bears upon the plate it isprovided with serrations which plate with a rail resting thereon; Fig. ,2 is' a side elevationof a portion of a rail, showing" the plate in section; Fig. 3 is an end view of a rail, showing the plate in section; Fig. 4 is an under perspective view of the plate.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawingsby the same reference characters.

The tie plate consists of a base port-ion 1 whlch 18 provided upon its under side with ribs 2 and which is provided at its inner end with a flange 3 adapted to overlap the base flange of the rail, indicated at 4. The plate is provided at opposite'sides of the rail with spike apertures 5, and the base portion 1 of the said plate is provided upon its upper side with serrations 6 which extend transversely acrossthe rail 4 under the base flange thereof. The rail 4 is provided upon the under side of its base flange with a series of serrations, indicated at 7, and when the rail is in position-upon the plate the serratlons upon the base flange thereof engage the serrations upon theupper surface of the plate, and one side portion of the base flange of the rail is inserted under the flange 3 of the plate. Spikes are then driven down into the tie through the apertures 5 and the spikes upon the one side of the rail have their heads bearing against the outer portion of the flange of the rail, while the heads of the spikes at the other side of the rail bear directly against the top of the plate 1. Therefore it will be seen that the rail cannot creep longitudinally for the reason that the serrations 7 at the under side of the base flange engage the serrations (5 and the rail cannot move laterally for the reason that the spikes at the one side of the rail have'their heads bearing directly against the base flange thereof. Also the rails cannot tilt or cant for the reason that the other spikes hold the plate 1 tight down against the upper surface of the tie. Also the plate 1 cannot move in any direction with relation to the tie for the reason that the spikes through the plate at both sides of the rail hold the plate down firmly against the tie and embed the ribs at the under side of the plate into the grain of the wood of the tie.

, Having thus described the invention, what is claimed as new is:

1. In combination with a rail havingof the rail adapted to engage the serrations upon the upper side of the plate, and spikes passed through the plate at the opposite sides of the rail, the spikes at one side having their heads in direct contact with the base flange of the rail and the spikes at the other side having their heads in direct contact with the top of the plate. 4

2. In combination with a rail having upon the under side of its base flange serrations, a tie plate provided upon its upper side with serrations which extend transversely under the rail and which engage the serrations provided under the. base thereof, said plate having a flange spaced from the base portion thereof and which lies over and in close contact with the baseof the rail, said plate having at its one side a spike perforation which extends from the top of the flange to the base of the plate and into which a spike may be inserted with its head bearing directly against the top of the plate, the plate having at its other side a spike perforation extending from the upper to the lower surface of the base and through which a spike may be inserted with its head bearing directly against the base flange of the rail, said plate also having upon its -un-.
