ANTICREEPING JOINT;

"Application filed March 10, 1926.: :Serial No. 93,713.

1 This invention relates to "means for, preventing the rails of a railroad track from creeping on the ties. T

An important objectof the invention is top'rovide an improved.aanti-creeping device adapted to be firmly secured to the rails and to r project downwardly between successive ties to engage the sides thereof.

A further 'object'of the invention is to mprovide a combined railjoint and anticreeping device independent of ,anyattachment to the ties and including-Va base plate for the rail joint, formed so as to extend f downwardly between two successive ties for 15 engagement with the faces thereof.

In carrying out the invention provision may be madeof a joint of a length to be included between successive ties and at the bottom of each rail or rail section of a downward extension or anti-creep device firmly secured to the rail section and located between adjacent ties. Preferably, these devices are spaced from each other distances equal to about the lengths of rail sections.

The anti-creep device, as herein disclosed, forms part of a rail joint connection which includes a base plate under the ends of the rails and adapted to be included between two adjacent ties and from which the anticreep device extends downwardly between such adjacent ties for engagement therewith to prevent creeping of the rails relative to the ties.

Other features and advantages will hereinafter appear.

In the accompanying drawings:

Figure 1 is a transverse vertical section illustrating one embodiment of the invention. 7

Figure '2 is a side elevation of a railroad track showing anti-creep devices between adjacent ties.

Figure 3 is a perspective view showing the various elements of the combined rail joint and anti-creeping device separated from each other.

Referring more particularly to the draw 'ing, rail sections 5 are supported on ties 6, and are fastened thereto in the usual way by spikes 7 to form a railroad track 8. The rail sections 5 are secured to each other at their ends by connections 9, each of which includes a base'plate 10 having an upwardly and inwardly turned edge 11 to form a flange 12 and a recess 13 to receive one flange 14 of the rail section or sections 5, the flange 14 fitting closely into the recess 13. Each connection also includes plates 15 and 16 at oppositesides of the rails and held together with theF-ends of the rails thereb-etween by bolts: 17 passing through suitable openings in the plates 15 and 16 and the rails, and

nuts 18 threaded on the bolts. Theplate 15 has a flange 19 at its lower edge extending overthe rail flange 20 to the base 10 and is .secured to the baselO by bolts 21 and nuts 22,the bolts 21 passing through suitable v-openingsin the flange 1.9 and the base 10.

It will be seen that each rail joint is of such vlength as to lie between two successive ties and is adapted to fast-en the rail ends to gether without any connection with the ties such as by spikes.

To prevent creeping of the rail relatively to the ties which may be embedded inany suitable road bed (not shown), each base 10, of the rail joints 9, is provided with an anticreep device 23 projecting downwardly therefrom. Said anti-creep device may comprise a rib or extension 24 which may be integral with the base 10 and preferably is formed therewith in the process of rolling. The rib 24 preferably extends vertically downwardly between two adjacent ties in the road bed and by engagement with the ties prevents the rails from creping with respect to the ties. It should be understood that, although the rib 24 may be located at any position transversely of the base 10, it is preferably located so as to be directly under the rail ends. According to the present invention no dependence is placed upon spikes to prevent creeping.

The rail joint or connection indicated in general by the reference numeral 9 is such as to make a very strong connection and although located between ties is strong enough to prevent the depression of the rail ends.

This feature except in the combinations set out in the claims is not part of the present invention and is disclosed and claimed in my Patent No. 1,517,124 of November 25, 1924. Although the plates 15, 16 and 10, all of which are preferably of rolled steel, provide a very strong connection, it will be evident that the rib 24 serves to strengthen the plate 10 and consequently the connection for supporting the rail ends against downward deflection. It should be understood that,.instead of having a rib extending the length of the plate 10, within the scope of the invention, provision may be made of other means to engage the sides of adjacent ends of successive railsjindependently of the ties in the road bed, a joint base having an.

upwardly and inwardly extending flange 1 along one side forming a rail base recess and having a downwardly extending flange extending the length thereof and adapted for insertion between and having engagement with ad acent ties to prevent creep ng movement of the rails orjoint, and a joint plate having a flange adapted to extend over the bases of the rails'and offsetdownwardly to form an abutment for the rail bases and perforated to form bolt openings registerflange along one side forming'a rail'base ne-' tioned joint plate by bolts ing with holes in said joint base, and adapted as to be secured to the latter by bolts and nuts,
