RAIL FASTENING DEVICE AND GUARD Filed June 3, 1936 v 1-Et. if "f5 INVENToR.'

Patented Mar. 8, 1938 UNITED STATES PATENT oFFicE 1 Claim.

My present invention relates to improvements in rail fastening devices and guards and has for its object to provide simple means for securely fastening the rails to the sleepers or ties as well as securing the adjacent rail ends together and prevent spreading, also to provide guards for trains jumping the track.

One object of my invention is to provide such a fastening device where no cross bolts through the rails are necessary. vThis considerably cheapens the construction and prevents railroad wrecks caused by loosened bolts.

The construction is particularly suitable for rail fastenings at curves where great strain is caused in one direction. My invention, therefore, prevents creeping and spreading of the rails at such places and provides means for keeping the train on the road bed in case of the wheels leaving the track.

In the accompanying drawing my invention is illustrated and Figure 1 is a sectional, fragmentary, perspective View of a track with my improved rail fastening device;

Figure 2 is a transverse section and partly perspective View of the track with a device for preventing spreading;

Fig. 3 is a similar section showing a side guard for preventing the train from jumping off the rail and Fig. 4 shows a` detail of Fig. 3;

Fig. 5 a transverse section and partly perspective view showing a guard rail and Fig. 6 a detail thereof;

Fig. '7 is a section and part perspective view of a sleeper with rail and guard assembled;

Fig. 8 a detail of Fig. 7, and

Fig. 9 a perspective section of a brace for the guard rails of Figs. 5 and 7.

Like reference characters indicate similar parts in the different views in the drawing.

The construction in Figure l shows the rail foot 9 resting directly on the smooth face tie-plate 40 which is secured to the sleeper I l by bolts or spikes and held in position by the spurs 2i). The clamping plate M has an arm 42 with an upstanding iiange i3 which lies flat against the rail web 8 and reaches nearly up to the head I t in order to give a rm support to the rail. There is preferably provided a clamping plate 42 on each side of the rail so as to firmly secure the rail in transverse directions to both sides. Bolts i9 secure the clamping plates 4I to the tie-plate lill.

In Fig. 2 is shown a construction with a sleeper Il and tie-plate 40 with spurs 2i) for the rails I0 which however are provided with a combined (o1. zas-33s) holding down and distancey plate it. This nxes the distance between the rails and prevents their spreading. This plate consists of a middle portion which lies flat on top of the tie-plate til and is secured by boltslilto the latter; At each end the distance plate 44 has an upwardly bent abutment portion 45 which `follows the contour of the rail foot 9 and with its end abuts against the web 8 of the rail. This arrangement prevents the spreading of the rails.

In Figs. 3 and 4 a side guard is shown toprevent a train from jumping off the track in the event that the rail Ill should break. This guard comprises a steel plate 46 heldin an upright, slightly inclined position near the rail by means of braces @l bolted to the guard plate it and the tie-plate i which as before is attached to the sleeper Il.

In Figs. 5 and 9, are shown upright standards 52 serving the same purpose as the guard rail 46, namely to prevent serious accidents if the train should jump off the track. It consists of an upright portion 52 and a at foot portion 53 in the shape of an inverted T, the foot being secured on top of the already described tie-plate lill by means of clamps 48 and 49. In this case the tie-plate 4l) has a smooth top surface with no lugs (see Fig. 6). The clamp 38, which has a ilat faced foot resting directly on the smooth top surface of the tie-plate t0, also serves as a distance member for accurately locating the standard from the outer side of the rail I which is also held down thereby on that side. The other side of the rail foot is held down by the inclined arm 5l of the clamp 50.

Figs. 7 and 8 illustrate the construction with guard standards 52 between the rails of the track. In this case the outer portion of the foot of each rail is held down by clamps til, 5i while the inner portion of the foot of each rail is secured by a double clamp 62 of the same shape as clamp d8 serving both for the rail and the guard standard. The inner portion of the guard foot 53 is held in position by the clamps 63, 54, all clamps being preferably bolted down directly on the smooth top surface of the tie-plate lll by bolts i9.

Lastly,in Fig. 9 is shown the construction of a guard standard 52, 53 which in addition to the securing clamps 54, 55, of the same contour as the previously described clamps 53, 6d, is also supported by a reinforcing inclined brace 56, abutting at its inner end against the upright arm of the standard and with its foot portion is bolted both to the clamp 55 and to the tie-plate dill by bolts 5l. This construction is used where the "CII track is exposed to great strain. The brace 56 has substantially the shape of the letter Z with its end edges bent back to contact with the upright arm 52 of the guard standard on the one hand and with the top surface of the clamp 54 on the other hand. It will be evident that the brace 55 is intended as an addition to the construction shown in Figs. 5 and 7 if so desired and Without any change whatsoever in said construction.

A further use of the Z-shaped brace consists in the feature that the plate for the guard standard is secured to the tie-plate at a point adjacent to foot of the standard and also at the point of contact with the Z-shaped bracing member. Accordingly the latter overlies and protects the securing means at a point adjacent the foot of the standard.

It should be understood that the invention is not limited to the details of construction here shown and disclosed but that these may be varied Widely Without departing from the spirit of the yinvention as dened by the claim.

I claim:

In combination With the sleeper for a track, a rail, a rail fastening device comprising a tie-plate having a smooth top surface and provided with sleeper gripping elements on its bottom side, a

guard-standard in the shape of an inverted T and placed spacedly to one side of the rail, a clamp lling the space between the upright webs of the rail and the standard and engaging the adjacent foot portions thereof, said clamp having aat faced foot resting directly on the smooth top surface of said tie-plate, securing plates for the non-adjacent foot portions of the rail and the guard-standard, and a substantially Z-shaped bracing member for the guard-standard with its end edges bent to form flanges respectively contacting With the upright web of said standard and With the corresponding securing plate, the plate for the guard-standard being extended to underlie the foot of said Z-shaped bracing member, and means for securely fastening the clamp, the bracing member, and the securing plates to the tieplate, the plate for the guard-standard being secured to the tie-plate at a point adjacent the foot of the standard and also at the point of contact with the foot of the bracing member, whereby the bracing member overlies and protects the securing means at the point adjacent the foot of the standard.
