ANTICREEPER FOR RAILWAY RAILS Filed June 25, 1930 2 Sheets-Sheet 1 March 31, 1931. DELLWQ' ANTICREEPER FOR RAILWAY RAILS Figed June 25, 1930 2 Sheets-Sheet 2 Patented Mar. 31, 1 931 UNITED STATES JOHN DELLWO, or FOREST LAKE, MINNESOTA ANTICREEPER FOR RAILS Application filed June 25,

This invention relates to a device for preventing railway rails from creeping.

It is an object of the invention to provide a device of this character which can be ap- F plied readily to a rail and, when properly secured thereto, will'bear against one side of an adjacent tie so that any tendency of the rail to creep or move longitudinally will be offset by the pressure of the device against in the tie.

Another object is to provide a device of porting the head of the rail, and for preventing the device from shifting relative to the rail.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention or herein disclosed may be made within the scope of what is claimed without departing-from the spirit of the invention.

In the accompanying drawings the preferred forms of the invention have been shown,

In said drawings a Figure 1 is a section through a rail having the anti-creeping device attached thereto.

at and- C respectively. This base has its underlying portion 2 increased in thickness toward one end so as to provide an extensive abutment '8 adapted to bear against; one sideof a tie T. A set screw 4 extends 55 into the bas'eat' a. point where it Will engage the upper surface of flange A close to the webB." A-brace 5 can be made integral with the so This braceis so shaped and proportioned as to fit snugly against the web Band the bottom of head C so as to constitute a' support for the head.- r

If desirechtheouter surface of the underlyingportion of the device can he waved or corrugated as indicated at 6 in Figure 3, and the brace 7 can be similarly shaped. I In this way metal is added in the form of ribs which materially strengthens the device and adapts it for heavier use. In the structure shown in Figures 3 and 4 the lower edge of the under.- .lying portions leading to the abutment 8 is also waved. Thus this portion will better engage the ballast between the ties and assist in holding the device against creeping. It is not essential that the bracebe made waved or corrugated. Instead it can be rounded from side to side as shown at 9 in Figure 5 or can be made fiat as shown at 10 in Figure 6. Furthermore, instead of providing a single set screw 4, two of these screws can be em loyed as shown at 11 in Figure 5.

In Figure the base 12 has been shown merging along curved lines into a relatively light brace 13, but it is to be understood that under some conditionsthe brace can be eliminated entirely as shown for example in Figure 8 wherein the base14= has its inner side bearing laga'inst web B which is exposed above the iase. V Inthe structures illustrated in Figures 5 and 6 the underlying portions 15 are provided with pronounced ribs 16 at the sides thereof which, with the waved lower edge 17 insures anintimate connection between the device and the ballast portions of which will be seated in thechannels 18 formed between the In every instance the underlying portion of the device includes an abutment for bearing against one face of the adjacent tie.

By providing braces extending to the head of the rail there is no danger of the device rocking and creeping laterally relative to the rail, because any lateral pressure due to side tilting of the rail will be transmitted to the brace and the attachment Will thus move bodily with the rail during such tilting or m lateral distortion.

What is claimed is V An anti-creeping attachment for railway rails including a base adapted to straddle and lit snugly upon a base flange of a rail, said 5 base having a depending underlying portion increasing in size toward one end to constltute a tie-engaging abutment, means carried by the base for gripping the base flange of the engaged rail, and a brace integral with 3n the base for hearing snugly against the web and head of the engaged rail, the brace and base being of equal length and there being depressions in the underlying portion of the base and in the brace for the reception of 3:. ballast, the depressions in the brace being extended from the top to the bottom thereof, and the depressions in the underlying portion being extended transversely thereof.

In testimony that I claim the foregoing as an my own, I have hereto afixed my signature.

JOHN DELLWO.
