: This invention relates to new and useful improvements in railwaytie plates.

' Y lappendedfclaims, and the, several views ,11-

It is'a well known fact that the available supply of tie timberhas been reduced to such an alarming extent that means must be provided for greatly enhancing the life of the wooden ties or some substitute 'tiemust be created. I

*It is also a well known fact that rails are generally secured to the'wooden tie through the medium of spikes which are driven into thetie at points immediately adjacentto the edges of theb'ase flanges of the rails, As a result of-these spikes being driven into the "wooden tie, the rain water and snow gravitate {into "the openings'aroundthe spikes and cause a rapid deteriorationof the tie to occur. As a result of the tie becoming dete- .riorated along and under the rails, the rails yery soon jbecome'loose and the track is rendered uneven, resulting in the early remotal of the afiected tie. 7

Among the several objects of my invention are. to provide a tie plate construction which will not-only cover the upper surface er the "entire tie but which will prevent water and snow from gravitating into the tie; to provide a tieplate in which-the rail fastening means donor; enter-the tie, together :wit-h means for fastening the :plate to the tie points. remote from thefrail fastening meansyand to provideatie'plate which is tremely simple in construction, is, therefore 'cheap to manufacture, durable operation, and will function to eliminate deterioration :ofthe tie by water or snow.

vVVith these and other objects view which" will more fully appear, "the -nature of the invention willfb e more clearly understood by following the description, the

lustrated the accompanying drawings. In the accompanyingdrawlngs:

Like reference numerals designate corresponding parts throughout the several ures' of the drawings.

Referring to th accompanying drawings, A indicates awooden tie and-B-B indicate the rails, each rail being of standard con stru'ctionand includin'g a head 5, web 6,

and base flanges 7-7. The rails '13 are seated upon the tie plates C(} which are positioned on the upper surface of the tie A.

Each tie plate C is formed from a single castingand includes a base 8 and depending side flanges-9-'9. The plates C are positioned on the tie so as to lap over the associated end, as indicated at 10 in Figures 1 sidesof theassociatedrail B and the dependng llanges 9 -9 extend downwardly along =the s1desof the tie A. The tie plates -G and 2. The tie plate C extends on opposite arespaced apart, and in order to protect the intermediate portion of the tie from exposure to the elements, I have provideda cover D whiclrmay be of sheet metal such asgal- -va'nized'iron or the like. This cover D extends under the inner edges of the tie plate C and is provided 'with depending side flanges 12l2 which extend downwardly "along the sides of the tie.

'Eac'htieplate Cis rigidly secured to the tie by means of lag screws 13 which are located at points remote from the adj acent rail 13. Each of these lag screws passes downwardly through an opening 14 formed in the base '8 of the tie plate and thence downwardl'y into the tie'forengagement with the latter; The upper surface of the base 8, around each'opening 14 ,is"formed with an angularrib 15 for engagement by the head 16 of the lag screw. The angular rib 15 forms a guard against the entrance of water into the opening 14 and the head 16 or" the screw by its engagementwith the angular rib 15, serves to further exclude water from entering said opening 14.

In order to securely fasten the associated vrail B to the tie plate C, I have formed the i 1 the tie plate.

base 8 of the plate with an integral lip 17 which engages one of the base flanges 7 of the rail; In order to firmly attach the other base flange 7 to the tie plate, I have provided a clamp 18 which is of inverted U-shaped construction. This clamp includes a top 19 depending legs 20-20 and fingers 21-21 which extend inwardly from the lower ends of thelegs 20 for respectively engaging the under edges of the depending flanges 9 9 of As shown in Figure 3, the

under edges of the flanges 99 of the tie plate are under-cut or beveled, and the fingers;21 -21 extend upwardly at the same anfingers 2121 andthe top 19 are disposed gl'es. The loweredges of the flanges 9-9 of the tie plate directly under the rail- B extend in a horizontal plane,- whereas the top 19 of the clamp extends inwardly in diverging relation. In other words, the

in diverging relation'so as to properly posi tion theiclamp onto the inclined upper face of thebase flange 7 of the rail. This diverging relation causes the clamp when slid into railengaging positionto have a wedging action so as to tightly en age the base flange of the [rail and secur ly retainthe latter in direct contact with the upper surface of the tie plate G.

operates to close the opening 22 against ingress of water. 7 a V v a In order to prevent the plate Cv from end- In order to secure the clamp 18 in position, Ihave provided the top 19 thereof with an opening 22 adjacent the outer edge thereof, and extending downwardly through, this opening is a bolt 23 having a threaded shank 24 for engaging'a corres ondingly threaded opening in the base 8 0 the tie plate. (It isto be observed that the lower endof'this bolt terminates above the under face of the tie plate, and consequentlyithis bolt doesnot enter or engage the wooden tie A.

Aniangular rib 25 is formed on the upper surface of the top 19 around the opening 22 for preventing the entrance of, waterinto said opening A lock washer 26, of i any suitable construction, is interposed between the rib 25 and the head of, the bolt 28: and serves not onlylto sccurelthe bolt against turning in the reverse. direction, but also co the ,wise movement onthe tie, I have provided the under surface, directly under the rail seat,

with one vor more transversely disposedribs 27, which readily project into the upper surface of thetie by the weight of a train 'passingover the rails;

From the foregoing, it will be observed that the meansfor fastening the rail to the tie is disposed intermediate the means for fastening the plate ,to the tie, and vconse- :quently there is no danger of injuring the tie directly under the rail.

- It is of course to be un without departing from the spirit and scope of my invention. -I claim 1. The combination with a woqden rail- Way tie, ofspaced tie plates supported onlthe tie andcovering the. end portions thereof,
