rails upon the ties and prevent spreading thereof.

A further object of the invention resides in the provision of a pivotally mounted retaining plate, and. means for locking the plate upon the rail tie against movement, such locking means also automatically'forcing the plate into its lookingposition with relation to the rail.

Still another object of the invention" is to provide improved means for mounting the rail fastening members upon the ties whereby a substantially continuousunbrokenisurface for the tie is provided.

A'still further object of the invention is to provide a retaining plate rotatably mounted upon the tie, said plate beingsubstant-ially rectangular in form and having its ends eccentrically disposed, the tie having under-cut grooves thereon to receive the ends of the retaining plate and limit the rotative movement of the plate in one direction, and additional means disposed through the retaining plate and the tie to force said plate into looking engagement with the rail.

With the above and other objects in View, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a detail perspective view of a portion of a tie having my improved retaining means thereon showing the same en- 7 gaged with the rail; Fig. 2 is a longitudinal section through the tie plate, one end there of being shown in elevation; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4

3 is a top plan view of'one end of the tie showing the retaining plate in inoperative position; and Fig. 5 is a detail perspective view of the retaining or fastening plate.

Referring in detail to "the drawing 5 designates the tie plate preferably constructed of steel and formed with a'central longit-udlnal depending anchoring web 6 which is gdipted to be firmly embedded in the track The upper surface of the tie plate ad-.

jacent each of its endsi has formed thereon the transversely disposed guide flanges 7 which are provided in-their opposed edges with the underrcut grooves or recesses 8. As my improved retaining or fastening means'is of the sameconstruction for each of the rails of atrack, only one of the same will be referred to in the following description.

A substantially rectangular retaining plate 9 is arranged upon the tie plate 5 between the guide flanges 7, and this retaining plate is of a width equal to that of the tie plate upon which itis rotatably secured by means of the rivet 10. The upper surface of the retaining plate 9 has formed sides of its pivot 10, a rail engaging lug 11 which is spaced from the upper surface of the retaining plate and is adapted for engagement over the edge of the base flange F of the rail R as clearly shown in Fig. 2. The ends of the retaining plate 9 are curved in eccentric relation to the pivotal point of said plate and each of said ends has a camlike flange 12 formed thereon and co-eXtensive therewith. These flanges gradually increase in thickness from one edge of the retaining plate to the other and are. adapted to be received in the under-cut grooves of the guide flanges 7 formed upon the tie plate, said latter flanges also increasing in thickness from one edge of the tie plate to the. other.. The longitudinally increasing thickness of the flanges 12 causes a proportionate decrease in the depth of the grooves 8. It will thus be-seen that when the retaining plate is rotated upon its pivot from the position shown in full lines in Fig. 4 to a position in parallel relation with the tie plate, the flanges 12 on the .ends ofthe tie plate move into the grooves 8 provided by the guide flanges'on theftie plate .and the upper surfaces of the flanges 12 frictionally engage with the upper walls of said under-cut grooves, such frictional, contact gradually increasing, until, when the plate is in its operative position as shown in Fig. 1 the same extends-throughout the entire extent of the flanges 12 and the grooves 8. This action prevents any rattling or loosening of the thereon at opposite ends and on opposite retaining plate in the movement of a train upon the rails, and also relieves the pivot 10 of strain.

In order to securely lock the retaining plate in its operative position and simultaneously force the flanges on the ends thereof into closer frictional engagement with the walls of the grooves 8 and also engage the lugs 11 firmly against the edges of the rail base, I provide a split key or spike 1a which is of the ordinary form commonly used for spiking railroad rails upon ties, but is constructed of a softer metal than the tie plate 5. This tie plate 5 is provided between the guide flanges 7 therein and at one side of the pivot 10 with a rectangular opening 15. The lower end of this opening is flared or widened as indicated at 15 in Fig. 3 and the opposite sides thereof are integrally connected by means of a rib 16 of substantially triangular-shape in cross section, the apex of said rib being upwardly disposed and substantially equal to a knife edge in keenness so as to open or spread the split portion of the spike. \Vith the rectangular opening 15 in the tie plate, a similar opening 17 which is centrally formed in one end of the retaining plate 9 is adapted to aline. Theseopenings receive the spike 14 which is forcibly driven into the same by means of a sledge or other suitable implement. As before stated, this spike is formed from comparatively soft metal and when the same strikes the sharpened apex of the triangular shaped rib 16 in the opening 15 of the tie plate, the spike is split longitudinally, and such split portion of the spike binds against the walls of the flared lower end of the opening 15 thereby securely locking the spike in position in said openings. The spike 14: is pro vided with the usual head 14: so that it may be readily withdrawn when desired. The plate 9 is moved into position upon the tie plate by hand until the flanges on the end thereof bind against the walls of the grooves or recesses 8. The retaining plate is not, however, in parallel relation to the tie plate as shown in Fig. 1 nor is the opening 17 in said plate in full register with the opening 15 in the tie plate, although the lugs 11 are in contact with the edges of the base flange. of the rail. The openings 17 and 15 are sufficiently alined to permit of the insertion of the spike so that its lower end will engage upon the edge of the rib 16. As this spike is driven into position, it tends to force the retaining plate farther in the direction of the arrow in Fig. 4: to effect the closer engagement of the flanges on the ends of said plate with the walls of the under-cut grooves 8 as heretofore noted, and thus cause an absolute lock of said retatining plate upon the tie. This additional movement of the retaining plate further causes the rail base enwith the base flanges, and thus prevent any longitudinal creeping or lateral spreading movement of the rails.

' i From the above description taken in connection with the accompanying drawings, it is thought that the construction and operation of the invention will be apparent.

The device is extremely simple, may be easily and quickly fixed in its locking position in engagement with the rail and elimihates the use of bolts and the necessity of handling a large number of tools in applying the fastener. As but two primary elements are employed in the construction of the device, it will be obvious that the fastener or retainer can be produced at a very low cost owing to the fact that these elements are of extremely simple form. Moreover, the device is extremely effective and provides an absolute lock, the retaining plates being immovable under all conditions when they have once been properly assembled in locking engagement with the rail flanges. Owing to the peculiar manner of mounting these rotatable retaining plates, the pivots upon which they are arranged are relieved of all unnecessary strains so that a maximum of durability is obtained.

It will of course be obvious that the tie plate 5 can be of any desired thickness or constructed of other material than steel and that if desired the anchoring flange 6 may also be eliminated. The same is true of the retaining plates.

A further and very important result of my invention resides in the fact that there are practically no abrupt-1y projecting parts upon the upper surface of the tie plate on which snow and ice can find lodgment, thus obviating the liability of breakage of any of the essential parts through expansion caused by the formation of ice thereon.

WVhile I have shown and described the preferred construction and arrangement of the various elements, it will be understood that the device is susceptible of considerable modification without departing from the essential feature or sacrificing any of the advantages thereof.
