EDWARD L. FLINN, or FORESTVILLE, 'o'nro, ASSIGNOR or ONE-HALF TO ARTHUR o. HERZOG, or MADISONVILLE, OHIO.

TIE-PLATE;

To wZZ whom/it may concern Be it known that I, EnwAnnL. FLINN, a citizen of the United States, residing at For estville, in the countyof Hamilton and State Fig. 1; and Fig. 4, a perspective view, on an enlarged scale, of the tie-plate turned upside down.

The tie-plate proper is in the form of a fiat plate Ayhaving a shoulder B overlap ing one edge of the flange c of rail C. On t 1e other side the tie-plate is provided with o enings CL, located a ong the edge of the rai -fiange and through which spikes D are driven into tie d, with their heads engaging the gods of the rail-flange. Outside. of shoulder B the edge of the plate is provided with notches a, through which spikes E are driven, with their heads engaging the plate. The shoulder B is intended to be placed on the outside of the rail, in which case the outside fastening of the tie-plate is made by spikes E, which are driven for their [1111 available length, and thus afford a very secure fastening at the outside or" the tieplate, where there is the greatest strain. On its bottom the late is provided with blades or ribs F and ada ted to be pressed into the tie d. The outsi e blades F are made slightly wider than the inside blades and notches f and g,'formed in both sets of blades, the notches preferably extending partly through the blades, thereby leaving a strengthening-rib for the plate throughout the length of each blade.

tion the blades are pointed at their outer ends to form entering edges. Then they are gradually thickened to points f and 9, then they are narrowed to points f and g and then they are thickened or'fiared considerably at their juncture with the plate A.

In use it is intended that the tie-plates be placed upon the ties with rails in position and the blades pressed into the ties by passing rolling-stock over them." Then the plates are further secured by the spikes D and E. When the blades are pressed into the ties, portions of wood of the ties are forced and compressed into notches f and g and serve to securely lock the plate against endwise movement. expands into the concavities in the neck of the blade, and thus forms an anchoring-lock against removal of the plate. The notches g in blades G are staggered'or placed out of line with notches f in blades F, so that there shall be no cross-section of the plate not reinforced and stiffened by blades F or G.

I claim as my invention- 1. The combinationnf a tie-plate; an overlapping shoulder at one side adapted to engage the rail-flange; holes along the edge of the rail-flange at the other side adapted to receive spikes; notches in the edge of the plate outside the shoulder adapted to receive spikes, and notched blades upon the bottom of the plate adapted to enter the tie, substantially as specified.

As the blades enter the tie the wood 2. The combination of tie-plate A; open- I alinement with each other, substantially as specified.
