i a This invention relates to'ti'e plates, rails,

and rail anchors,"for use in' railway track construction; More particularly the invention relates to tie plates andrails s ecially constructedjto have cooperative inter ocking relation, whereby the rail may be prevented from creeping withrespect to the plate:

- An object of the-invention is to provide an improvedtieplate which will be interlocked with aspec'ial rail baseto prevent "creeping. "A'further object is to provide a special rail base having abutments adapted to cooperate'with a tie plate and/ or retaining spikes to prevent creeping of the rail.

3 As is well known by those familiar withtrack construction,there is a tendency of rails to creep along the track in the direction of the travel of trains passing thereover. This creepage has many objectionable results, and it is customary to prevent it by the application of-anchors to the rails. Usually the anchors heretofore used are in the form of spring clamps applied to the rails in such position that they Wlll abut against adjacent x ties.

sult only by slippage of the anchor on the Thereaftercreepage of the rail can rerail, by movement rof the tie, or by cutting into the tie of the rail anchor. These devices 7 v are quite expenslve in themselves, and they areexpensive to apply and maintain.

It is the custom in track construction to lay the rail on a tie plate positioned on top of a Wooden tie embedded in the track ballast.

Sometimes rails are laid on the ties without the ties,

plates. spikes or screws adapted to fasten them to I of the rail on the plate.

plate and rail base whereby there may be pro- .vided aninterlock between the rail and plate and usually they have a retaining rib or ribs adapted to prevent lateral slippage The present invention has for its principal 7 object a cooperative construction of a tie.

surfaces are provided on the under side of the rail and on the upper side of that portion of the plate on which the rail seats; Fig. 4 shows a modification in which the side corrugations of Fig. 1 and the bottom corrugations of Fig. 3 are both used; and Fig. 5 shows aperspective view of the underside of a rail having projections and recesses on both sides and bottom of the base.

The preferred form of my invention is shown in Fig. 1, wherein a rail 'R is shown seated 1n a special tie plate P. It will be understood that this plate is normally positioned longitudinally upon a conventional wooden tie T, and spiked or otherwise fastened thereto. The tie plate has an intermediate recessed rail seating portion 1, with either a level or sloping base,'and perforated end portions 2 and 3. Holes 4, 5, 6, 7, 8, and

9 are provided in the portions 2 and 3 to receive spikes, screws, or other attaching members, according to whether the tie is of wood, concrete, composition, metal, etc.

' The shoulders bounding the recessed portion 1 are formed with undulating or verti-' cally corrugated walls 10 and 11 having re- .cesses 12 and projections 13.

The particular size and shape of the proections and recesses 12 and 13 may be widely varied. They may be comparatively large and of truearcuate shape, as shown in Fig. '1, or they may be reduced to quite small angular serrated projections and recesses, or

any intermediate shape. The tie plates are punched to receive The spike holes'5, 6, 7, and 9 are preferably positioned so that the shanks ofthe spikes passing therethrough will be positioned near the extremity of one of the projections 13.

The rail R cooperatin with this special tie plate has the vertical edges of its base flanges corrugated to form recesses 15 and projections-16 complementary to those in the tie'plate shoulders. "Consequently when the plate is placed-on a tie and the rail positioned thereon as shown in Fig. 1, and the plate fastened tothetie by spikes or other means, the rail will be securely fastened to the tie plate and prevented from movement; relative thereto in any direction. The interlocking "recesses and projections 12 and l3on' the plate, and the cooperating complementary projections and recesses and 16 on the rail form a positive interlock so that the rail can recess across the face thereof, the bottom of the recess being divided into alternate ribs and recesses, and a rail adapted to seat upon 7 the said plate in said rail-receiving recess rails and plates at every tie the creeping and having recesses and ribs adapted to co- 7 p v tendency is distributed over the entire track, operate andinterlock withthe said ribs and l and no; undne-st raih is put upo n 'any particu- 'recesses of the :tieplate, whereby to form a lartie, as in the present practice, wherein positive interlock between the rail and tie 1'0 anchors are applied at intervals spaced sevplate. v g eral tiesapartL- i 2.
