6 Claims. (oi. est-ass) It is desirable to spike tie plates on railroad ties to gauge at a shop or other place equipped with jigs and tools for the purpose and to ship the ties thus prepared with the necessary rail clips 5 and bolts to the place where they are to be put in the track, leaving the track man the simplest possible job in fastening the rails to the ties.

For obvious reasons it is not desirable to insort the bolts before spiking the plates to the ties l and it is very objectionable to make holes in the ties for the bolt heads because that not only requires an additional operation but makes pockets for water to collect and promote rotting. 15 A great many expedients have been 0 ered to meet the situation. For examples, slots have been made through the plates or the shoulders or bore into which the bolts were to be inserted and some have made the walls of the slots in- 20 ciined and the bolt heads to correspond.

In many instances the slots have required a milling or other expensive machine operation that made .the cost prohibitive. In others the bolt heads were notsecurely fixed and the un- 25 avoidable movement of the tracks under trains made the fastening unreliable. What with one defect or another, the needs of the service have not been met.

The principal object of this invention is to ::0 provide a construction that can be had at low cost and will make a reliable rail fastening under modern high speed trains.

Figs. 16 and 17 are side elevation and inverted plan view, respectively, of the bolt lock shown in Figs. 13 and 14.

But these specific illustrations and the corresponding description are used for the purpose of 20 disclosure only and it is realized that the substance of the invention may be put in other forms. j

In the drawings the tie plate in isshown fixed to a wooden tie it by four screw spikes i2. Prefr erably the bottom it of the plate is plain and free from projections sometimes used to bite into the'wooden tie. On the top of the plate there are spaced shoulders it defining a rail seat i5 between them which is also preferably plain and fiat'to avoid concentrating stresses on the rail.

At each side of the rail seat and preferably beyond the shoulders M elongated bolts holes ilii are provided which extend entirely through the plate to permit the heads ll of bolts it to be insorted from the top after the plate has been spiked to the tie.

As shown in Figs. 3 and '7, which are inverted plan views, the tie plate is countersunk on the bottom at iii to provide seats for the bolt head 40 ii into which it can be turned by approximately one-quarter of a revolution.

The countersinks i9 extend from each end of the elongated hole It at one side only and stop short of the other end of the hole.

In this particular embodiment the walls of the countersunk portion lie on an arc struck from the center 20 for somewhat less than onequarter of a revolution. From there the countersunk portion is struck on a shorter radius from the center 2i to the intersection with the elongated opening at 22. v

This construction permits the bolt head to be inserted through the elongated hole l6 and then rotated to a pofltion at rightangles to the (ill major axis of that hole when it is stopped by shoulders 23. Naturally the shoulders 23 are so placed as to hold the bolt against rotation as the nut 24 is screwed on and set up.

The elongated opening I6 and the countersunk portions l9 are preferably formed by a punching operation, diagrammatically illustrated in Fig. 9, where a portion of the plate Ill is shown between the male and female dies 25 and 26 which have just formed the elongated holes l6 and the countersunk portions, displacing metal corresponding to the countersunk portions and forming flanges 21, constituting an integral protuberance, at the upper side of the tie plate and thereby preserving approximately the entire thickness of metal above the countersunk seat for the bolt head ll.

- In order to insure that the bolts will not work loose and unfasten under the movement of trains, it is desirable to lock the bolt heads ll against rotation from the countersunk'seats l9.

In the preferred form this is accomplished by a forked lock 28 havingfingers 29 adapted to be received within the elongated opening l ateach side of the bolt and thus lie in the path of the reverse rotation of the bolt head, as best appears in Figs. 5, 6 and 7.

The upper portion of the lock is bent over at 30 to lie alongside the bolt and under the rail clip 3|, as shown in Figs. 2 and 5. Obviously, as long as the nut 24 is on the bolt the clip will remain in place and the lock will remain in position to prevent rotation of the bolt head I1.

In an alternative form shown in Figs. 10, 11 and 12, the lock is formed as a depending finger 32 on the rail clip 33 and iscurved on one side to fit and practically fill the elongated opening I6 by the side of the bolt head ll, as best appears in Figs. and 11. In this form the lock can be made by a punching operation that first forms the hole 34 in the rail clip and then shapes the lock substantially as shown.

In the alternative form shown in Figs. 13 to 1'7, the lock is formed as part of a spring lock washer 35, depending

arms

36 and 31 being practically continuations of the ends of the lock washer, which is given a somewhat pear shape, as best seen in Fig. 1'7. This form has the advantage that a single part performs the function of locking the nut and locking the bolt, and saves handling. In order to bring the arm 31 within the compass of the elongated hole IS in the tie plate, the lock washer 35 is given a little excess of curvature at 38 (Figs. 16 and 17) Naturally, the rail clip 33 for use with this form of lock is provided with an elongated opening 40.

With the bolt lock shown in Figs. 1 to 12, the bolt is equipped with a familiar form of lock washer 4|.

The construction of tie plates shown permits the bolt hole and countersinking to be done by a single'punching operation at very low cost. The displacement of the metal by which the countersunk seats are made retains the full strength of the plate for cooperation with the head of the bolt. In addition, the flanges on the upper side assist in locating the rail clips.
