1 claim. (ci. 23S-assi anchor inthe fo'rm'of'a tie plate assembly for anchoring and Ebrairig `railroad rails, and to prevent spreading orV creeping" of "the rails.

vThe primary object of the .invention is the rprovision of a tie plate assembly ,that is composedV of a minimum number; of yparts which may be pressed or stamped to shape withfaility and low cost of production, and assembled with convenie'nce towproduce a mechanical structure that is safe and durable, and Whichniayreadily spectedand maintained-in perfect service condition.

The invention consists essentially in certain novel features of construction and combinations and arrangements of parts involving a deformable tie plate, which under the load of passing trafc, is caused to grip and lock a rail in its seat, and in other parts of the assembled structure, as will hereinafter be described and more specically set forth in the appended claim.

In the accompanying drawings we have illustrated one complete example of the physical embodiment of our invention, together with variations or modifications thereof, wherein the parts are combined and arranged according to modes we have devised for the practical application of the principles of our invention. It will however, be understood that changes and alterations may be made in these exemplifying drawings and mechanical structures, within the scope of our claim, without departing from the principles of the invention.

Figure 1 is a. view in elevation and broken away, showing a tie and spaced rails, and the spaced tie-plate assemblies connected or united by a tiestrap; and

Figure 2 is a top view of the structure in Fig. 1.

Figure 3 is an enlarged detail sectional View through a rail, with the deformable tie plate in initial position; and Figure 4 is a similar view with the jaws of the deformed tie plate automatically locked against the rail base, after passage of railway traffic.

Figure 5 is a detail sectional view at line 5--5 of Fig. 1, showing the use of a supporting shoe in the locked tie plate assembly, together with one end of the attached tie strap.

Figure 6 is a perspective View of a fulcrum-supporting shoe that may selectively be employed in the tie plate assembly.

Figure 7 is a View similar to1Fig. -5, -but omitting the shoeofFiglfd I'flfn or,A erthat th ygeneral arrangement-andrelation of {parts `may?readily" be understood we have illustrated in the4 drawings afconventional Cross-tie 'IL with, the, laterally spaced. falrged rails-MR.mauritesthsreen# blies are of course utilized The .tie rlaie'asse in pairs" *and the para pf.. the assembit-iie-.iritse Charge, legi ofrdsr that te? @qui ent maybe landscaping@ ecwlth'faelity .achat-.tee assemblies infringes intesfal .t amable 9? bendable rectangularfplate'flon t vupper sur-A face @which is ,entlassen ,cf ...paced ,transerslelyV exte'ding'angul'ar bosses Za'nd '3 that are designed to perform the functions of gripping jaws against the lateral edges of the rail base.

The pair of angular bosses form a seat for the rail base, and alongside of one of these bosses or gripping jaws the rail seat is fashioned with a transversely extending groove 4 in the upper face of the seat, or plate, and the usual spike holes are arranged in pairs to receive the fastening spikes 6 that enter and penetrate the tie.

In addition to the spike holes, groove, and bosses, the tie plate is fashioned with an upstanding lug 'l that is punched from a central point and near one end of the plate, and these features or elements of the plate are preferably stamped or pressed in a single operation of a suitable power machine or tool.

A pair of the tie plates, mounted upon a tie, may be connected or united by a metallic tie strap 8 that is punched with holes and spiked to the tie, and at its ends the strap is equipped with openings, loops, or sockets 9 which are slipped over and frictionally engage the upstanding lugs 1 of the tie plate. The socket-ends of the tie strap are slightly upset to engage over the inner end of each of the pair of tie-plates, and the strap is rmly secured to the tie by means of spikes to prevent spreading of the plates or creeping of the rails.

In some instances an interchangeable shoe l0 of generally rectangular shape, having a flat under side and a rounded upper face Il is utilized as a supporting fulcrum in connection With the deformable or bendable tie plate.

When used this metallic wedge-shaped shoe is slipped under the inner end of the plate, transversely of the upper face of the tie, and the shoe is solidly spiked to the tie. With the plate and the shoe in this position and with the inner end of the plate slightly elevated and resting upon the shoe, as in Fig. 3, the four pairs of spikes are driven home, thereby deforming or bending the plate along the line of the groove 4 to position of Fig. 4.

In the position of Fig. 4 the two parallel bosses 2 and 3 of the tie plate are gripping the opposite edges of the base of the rail R, the major portion of the plate resting iiat on the upper face of the tie, and the load imposed by passing traffic on the rails tends to enhance the grip of the bosses on the rail base.

In Fig. 5, where the shoe l is employed, the tie strap is anchored directly above the shoe on the lug "l of the plate, the major portion of the plate rests atly on the tie to which it is spiked, the shoe is spiked to the tie, and the up-sprung socket end of the tie strap is firmly held in engagement with the lug of the plate by a spike driven into the tie adjacent the socket end of the strap.

In the assembly of Fig. 7, the shoe is omitted, and the entire plate rests atly upon the tie to which it is firmly spiked, and the socket end of the tie strap is rmly spiked to the tie with the strap in rigid engagement with the lug of the plate.

From this description taken in connection with the drawings it will be apparent that the tie plate assembly of malleable metal includes coacting parts that adapt them for various purposes in railroad construction and maintenance, and the parts may be combined and installed with convenience, to insure safe and durable supports for the rails.

Having thus fully described our invention, what we claim as new and desire to secure by letters Patent is:

In a tie plate assembly for locking a pair of spaced parallel rails on a crosstie, a pair of plates supported on said crosstie, a plurality of bosses projecting from the upper surface of each of said plates and secured to the latter, said bosses defining jaws for gripping said rails, a lug projecting from the upper face of each of said plates, a tie strap extending between said pair of plates, there being a socket contiguous to each end of said tie strap for the reception of said lugs to thereby prevent lateral displacel ment of said rails, a plurality of spikes extending through said tie strap and through said plates and a shoe positioned under one side of each plate, inclining each plate, so that the rail bearing portion of each plate is bent into contact with said tie, when said spikes are driven into said tie, forcing the bosses into gripping relation with said rail.
