, TIE-PLATE.

Specification of Letters Iatent.

Patented Apr. 22,1913.

vision is made for preventing the same from.

creeping or moving sidewise upon the tie, such movement to be prevented by means of spurs so located and arranged upon the under side of the plate as to ofi'er a maximum resistance to the movement thereof.

A further object of my invention is to provide spurs so formed and arranged that they will readily and easily enter the tie, and with but little or no injury thereto.

With the above and other ends in view,

the invention consists in certain n'ovel fea-.

tures of construction as will be hereinafter fully described and pointed out in the claim. -In the accompanying drawings, Figure is a plan view of myimproved tie plate; Fig. 2 is a view showing the under side thereof; Fig. 3 is a view showing an end elevation thereof with a portion of a rail and securing spikes; and Fig. 4 is a view in side elevation of my improved tie plate as seen from a position to the left of Figs. 1 and 2.

Referring to the drawing, the reference I numeral 4 designates my improved tie plate as a Whole, the upper surface thereof being provided with side ridges 5, against which the outer edge of the base of the rail abuts when the plate is in place, as will be under-.-

stood from Fig. 3. The tie plate is provided with holes 6, through which fastening spikes pass into the tie beneath the plate, lugs 7 being provided at the outer sides .of the holes to afford support for the spikes as illustrated in Fig. 3. The under side of the late is provided with downwardly projectmg side spurs 8, these spurs being located beneath that portionof the late engaged by the side edges of the rail w en the latter is in place, to thereby strengthen the plate at the place where it is somewhat weakened by side edge. The spurs therefore strengthen.

the plate at the points where it is subjected to the greatest strain, and also at the points where is weakened by the holes through whichthe securing spikes pass.

The number of side spurs 8 employed is immaterial, and depends largely upon the service to which the plate is to be subject ed. In the drawings, I have illustrated three such spurs upon the outer side of the rail, and two upon the inner side, although it will be understood that the number thereof may be increased or decreased, as desired. These spurs extend transversely to the rail as shown, the outer ends 9 thereof being made square, or at right angles to the face of the plate, in order to thereby increase the resistance to outward movement of the plate when the same is ,in service.

In order to still further resist sidewise movement of the plate, I provide a downwardly projecting spur 10 u on the under side of the tie plate and deslgned to enter the tie. This spur is located between the side spurs 8, and preferably beneath the central web of the rail as shown in Fig. 3, so that the weight imposed thereon acts directly over said central spur to force it into the tie. The spur 10 is preferably of considerable length, and so arranged as to extend longitudinally of the rail.

The side spurs 8 will be seen to extend in the same direction as the grain of the wood of the tie, so that they will enter the latter with a minimum of injury thereto. The central spur 10, however, preferabl extends transversely to the aim of the tie, but being located beneath t e central portion of the plate, it follows that if any injury be done b it to the tie, it is localized, and at a conslderable distance from the side spurs.

Having thus described my invention, I claim and desire to secure by Letters Patent:-

A tie plate havingdownwardly projecting side spurs upon its under side located beneath that portion of the plate engagedby the'side edges of the base of the rail and extendingtransverse to the rail and part tral portion of the plate is unobstructed by Signed at Meadvi11e in the county of said. spurs 5 a centrally arranged down- Crawford and State of Pennsylvania this 10 wardly pro ecting spur extending 10ngitudi' 19th day of January A.
