'10 all whom it may concern:

Be it known that l, Aximicw .\loiiiiisoi\',

a resident of Pittsburg, Allegheny county,

ful Tie-Plate for Railways, of which the following is a full, clear. and exact description,

drawings, forming part of this specification, in which-- Figure 1 is a bottom plan view of one form of tie-plate embodying my invention; Fig. 2 is a longitudinal section; Fig. 3 is an end view; and Fig. -l is an end view showing a modification.

My invention relates to tic-plates for railways of that class in which the plate is provided with longitudinal flanges at or near its lateral edges for the purpose of causing the the maximum load is sustained by the tieplate at or about the base of the shoulder 5,

i and by providing one of the transverse ribs 4 Pennsylvania, have invented a new amt useat either side thereof, these ribs will embed themselves equally in the tieand thus afford a maximum resistance to the lateral movereference being had to the accompanying late to adhere to the tie' and is desi 'ned to i provide a tie-plate of this character with means in connection with the longitudinal flanges for giving the tie-plate i'tstslzliit'fil against endwise movement on the tie.

The precise nature of my invention will be best understood by reference to the accom panying drawings, which will now be described, it being premised. however, that various changes may be made therein by those skilled in this art, without departing from the spirit and scope of my invention. as defined in the appended claims.

Referring to th se drawings, the numeral 2 entire width of the plate.

ment of the tie-plate.

As shown in figs. 1, 2 and3, the trans verse ribs 4 terminate at the inner sides of the longitudinal flanges 3. In the form of the invention shown in Fig. 4, however, these ribs are extended outside of the flanges 3, and thus extend substantially across the These cross ribs may. however, be of less length than the distance between the llangcs 31. and any suitable number of them may be provided. distributed at the desired points throughout the' length of the plate. l have found that these transverse ribs are particularly ell'cctive, when used in combination with the longitudinal adhesion flanges in the manner herein shown and described. for the reason that the llanges in penetrating the tie conipress and contine the tibers ot' the tie between them, thus insuring the putting of the libers in the best condition by increasing the density thereof to give the most etl'ective lateral resistance.

While l do not limit myselt'thereto, yet the I plate herein described is one that can be designates the plate, which is preferably a rolled plate, provided on its lower face adjacent each edge w th a deep adhesion llange 3.

Extending transversely of the plate are one or more transverse ribs 4, extending at substantially right angles to the longitudinal fla'nges 3, and which are adapted to embed themselves in the upper portion of the tie to ell'ectively prevent any endwise movement of the plate. The sides of these transverse flanges, as well as-thc lateral faces of the longitudinal llangcs 3, are preferably beveled, as shown, although they may be of any suitable cross section.

5 designates a transverse shoulder upon the upper face of the tie-plate, against which the outer edge of the rail bears.

' hi the form of my invention illustrated. two of the transverse ribs 4 are shown, one inside of the rail-bearing shoulder 5, and the other outside of such shoulder. While l do not limit myself to this arrangement, it is, however, a preferable one, for the reason that readily formed by rolling. so that it can be cheaply mamilzu-tured.

What I claim is;

l. A railway tie-plate having a deep adhesion lhuige iuljacent t each of its lateral edges, and a lateral resistance rib extending transversely of the plate at approximately right angles to the dire tion of the flanges, said rib being of less depth than the tlanges, substantially as described.

2. railway tie-plate having a longitudi nally extending deep adhesion llange, and a transversely extending lateral resistance rib of less depth than the llange, substantially as described.

It. A railway tie plate having longitudinally extending adhesion llanges ou'its under side, there being one ol such llanges adjacent to each edge of the plate but inset inwardlv 4. A railway tie gate having a deep adopposite sides of the shoulder, substantially hesion flange at eac of its lateral ed e p01- as described. lu. time, a, transverse mil bearing sho der on In testimony whereof, I have hereunto set its upper surfsce and two ieteml resistance my hand.
