TIE-PLATE.

Specification of Letters Patent.

Application filed. August 4,

Patented Oct. 13, 1914.

1913. Serial No. 782,987.

To all whom it may concern:

Be it known that I, lViLLrAM E. MILLER,

a citizen of the United States, residing at- .Palisadc, in the county of Eureka and State of Nevada, have lnvented a new and useful Tie-Plate, of which'the followlng 1s a SPGCl fication.

The present invention relates to improvements in railway tie plates, one object of the invention being the provision of a tie plate provided with two parallel tie embracing members, thelower edges of which are of relatively thickness so as not to cut into the tie and at the same time to be properly reinforced to prevent the ends of the plate turning up due to the weight of the rail and load'thereupon and to also prevent the tie plate from twisting and turning relatively to the tie.

A further object of the present invention is the provision of a metal tie plate which is readily constructed in a rolling mill and cut to the desired length.

A still further object of the invention is the provision of a tie. plate having tie embracing parallel members and upon the upper face of which is provided a rail abutment.

A still further object of the present invention is the provision of parallel grooves near the edges of the upper rail bearing surface of the plate which prevents the collection of moisture under the rail bases and provide for the desirable draining of the tie plate.

With 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. I

In the drawingsFigure 1 is a top plan view with the present tie plate as positioned upon a set of switch ties, with the rails spiked and fastened thereupon similar to when the common flat bar steel is used. Fig. 2 is a perspective view of the tie plate. Fig. 8 is a perspective view of the tie plate provided with the rail abutting projections.

Referring to the drawings, the numerals 1 and 2 designate the long and short frog tie as is the common practice.

and guard rail platesof the switch, as shown in Figjlf The tie plate 3 fora singler'ail is provided with ashoulder 4, as clearly shown in Fig. 3, pressed or rolled out of the center and acts in a similar manner to the abutment as shown in the tie plate in the patent to William E. Miller No. 781,218 dated January 31, 1905. This shoulder at is disposedto be placed upon the outside of the rail and upon certain of the ties, as clearly shown in Fig. 1. The two parallel tie embracing ribs 5 and 6 are formed integral with the tie'plate and thus with the'under side of the tie plate form a tie embracing member capable of withstanding a tremendous pressure, from above without the tendency to bend or curl up theends ofthe tie plate as'is'the case where corrugated or flat plates are employed and rest only upon" the upper surface of'the The lower end of the ribs 5 and 6 may be either square i or rounded but being in paralleland ex tended from the main body of the plate pro vldes the necessary reinforcement- WVith this form of tie plate, the ribs 5 and 6 constitute as before described, a reinforcing means to prevent the up bending or twisting of the plate, it having been found that the plate can be disposed tohave one end fit-' ting astride the end of one tie while the other end fits astride the end of another tie, I

the members or ribs 5 and 6 receiving a rail disposed upon the upper surface of the plate between the ends of both ties without any the plate. this character provides a reinforced tie plate which cannot possibly be bent transversely so that the rail bearing surface is moved out of its original plane.

To provide a means for increasing the rail bearing area of the tie plate and at the same time to reinforce the ribs 5 and 6 adjacent the junction thereof with the main body of the tie plate, the enlarged portion 8 is provided, the same extending throughout the length of the tie plate and as clearly illustrated in Fig. 1 constituting the main projecting portion beyond the respectivefaces of the ties when the plate is in position. Thus the ribs 5 and 6 prevent the curling or upturning of the ends of the plates while the reinforcements 8 prevent the outbending of the ribs and also increase the rail bearing the flat tie area. This feature in a plate of this char acter cannot be too greatly emphasized, for where a plate constructed of a channel iron is provided, the ribs which embrace the tie have a tendency to spread and consequently deflect the upper surface of the tie plate from the desired level plane.

In order to provide a means for preventing the collection of moisture below the rail base when positioned upon the tie plate, and as shown in either Figs. 2 and 3 and upon the upper surface of the tie plate, the two parallel grooves 7 are formed in the upper surface adjacent the edges and provide drainage grooves for the tie plate.

From the foregoing description, taken in connection with the drawings it is evident that with a tie plate constructed according to the presentinvention that is having fiat or rounded edges upon the tie embracing ribs 5 and 6, atie plate capable of withstanding a tremendous pressure is provided, one that will not have its ends curled due to the load pressure thereupon and which due to the embracing members will not twist or turn relatively to the tie. lVith this form of tie plate, the same will not rip at any point and especially where the point of pressure comes thereupon as is the fault with plates either provided with the knifed or spiked under side for engagement with the under surface of the tie. WVith this form of tie plate, the under surface of the main body of the plate is smooth and therefore does not cut into the upper surface to lac-crate the tie.

What is claimed is:

1. A tie plate, having two paralleled ribs depending at right angles from theedges of the plate for embracing the rail carrying portion of the tie, the upper surface of the plate being provided with moisture draining recesses, said recesses being alined with p the ribs to direct the collected moisture to each side of and away from the tie.

2. A tie plate, having two parallel depending ribs, the inner faces of which are at right angles to the under face of the plate while the outer face at the junction of the plate is projected longitudinally beyond the outer face of the ribs to form a reinforcement thereat, said ribs and the under side of the plate being disposed to embrace the tie, the upper surface of the plate at a point adjacent the approximate center line of the ribs being provided with two longitudinally disposed moisture draining recesses, said recesscs being open at their ends.

in testimony that I claim the foregoing as my I have hereto ai'li xed my signature in the presence of two witnesses.
