TIE-PLATE.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed. May 6, 1912. Serial No. 695,408.

To all whom it may concern Be it known that I, WILLIAM E. MILLER, a citizen of the United States, residing at Palisade, in the county of Eureka and State of Nevada, have invented a new and useful Tie-Plate, of which the following is a specilicat-ion.

This invention relates to improvements in tie plates, the primary object of the invention being the pro-vision of a tie plate especially adapted for use in connection with the main rail at curves and at switches, and consists primarily of a plate which embraces the tie and is extended the proper distance upon each side of the rail flange to provide the proper support for the rail flange and to prevent the cutting thereof into the tie and the consequent upsetting of the rail due to such wear.

A. further object of the present invention is the provision of a tie plate provided with a plurality of rail flange receiving ribs together with downwardly projecting parallel ribs, which coact as a reinforcing means for the plate to prevent the same being curved upwardly at the ends thereof due to the weight of the rail and the traiiic thereupon, said tie plate being further provided with means whereby rails of varying weight and flange width may be accommodated without the necessity of providing various sizes of tie plates for such use.

it-h the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a perspective view of the tie plate. Fig. 2 is a plan view of a switch with the tie plate in use.

Referring to the drawings, the numeral 1 designates the supporting plate or platform of the tie plate which as shown is provided with the longitudinal recesses 2 upon the upper face thereof which provide the min forcing and rail flange receiving ribs 3 and the depending parallel ribs or girders 4.

By this means the weight of the rail flange upon the tie plate is properly taken care of without the consequent upward bending of the extreme ends of the plate.

The tie plate is made of suflicient length to project the proper distance under the rail flange to prevent the cutting of the tie plate into the tie 5 and as each plate is provided with the parallel webs or girders 4, the plate will fit upon the tie as clearly shown in Fig. 2, and thus embrace the tie upon the upper surface and sides thereof to prevent any turning of the plate upon the tie and at the same time protecting the tie at the contact portions thereof.

Formed in the extreme end of the ribs 8 are the spike receiving apertures 6, which when the plate is properly positioned upon the tie permits the introduction of spikes therein'to retain the tie plate upon the tie to prevent any longitudinal movement of the plate relatively to the tie.

Formed in the ridges or ribs 3 are the re spective spike receiving apertures 9, 9 and 9 to receive a light rail or a narrow flanged rail, an intermediate rail, or the widest flange rail, thus making the tie plate a stock plate with means for accommodatng the various rails now employed. The spikes for engaging the inner flange of the rail are in serted through the respective apertures 9, 9 and 9 and pass into the tie thus properly supporting the rail in the usual manner. The tie plate in this instance, has the ridge 10 which is elevated above the plane of the ribs 8, and terminates in the apertured lug 11 so that the switch point 12 is permitted the desired movement thereupon and is properly supported.

By providing the flanges 4, which with the base 1, forms a receptacle to receive the tie, it is evident that the tie plates will not turn relatively to the tie and that the same will be properly positioned at all times thereupon, and by reason of the fact of the holding spike receiving apertures 6, the said tie plate is properly secured upon the tie against longitudinal movement. These tie plates may be made in varying lengths and by reason of the ribs 3 and the parallel girders at, the positioning of the rail flange upon the plate is so proportioned as not to cause the turning or bending up of the we treme ends of the plate and the usual distortion of the plate is now the case. It is evident that with this form of tie plate, that the tie and the rail supporting portion thereof will be fully protected and by reason of the length of the tie plate, the undue cutting of the tie due to the weight of the rail and traffic thereupon is prevented, and as before stated by reason of the longitudinal ribs 3, the supporting surface of the plate is reinforced so that the plate does not become distorted as would be the case if the surface were perfectly flat and no flanges were employed.

As carefully noted it will be seen that the portion of the tie plate at the junction of the parallel ribs 4 with the portion 1 of the tie plate is reinforced or enlarged as at 4, thus strengthening the tie plate so that the tendency of the tie to bulge or separate the plate is overcome, and rendering a rigid plate which may be properly seated or driven upon the tie previous to the spiking thereof in place.

What is claimed is A metal tie plate, having two parallel tie embracing flanges of equal depth and substantially the full length of the body of the plate, the rail engaging surface of the plate being provided with a plurality of reinforcing parallel rail holding ribs the full length of the plate and having their upper surfaces in the same facial plane, said tie plate being provided with apertures to receive spikes for securing the tie plate to the tie and the rail upon the tie plate and tie, the central rib at one end being provided with a switch point guiding abutment the facial plane of which is above the facial plane of the rib and further terminating in a limiting shoulder for the switch point.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
