Application filed August 31, 1921. Serial No. {197,088.

To all whom it may concern:

e it known that I, ORVILLE M. KNOX, a citizen of the United States, residing at Knoxboro, in the county of Oneida and State of New York,-have invented certain new and useful Improvements in Railway Crossties, of which the following is a specification. V

This invention relates to metal railway cross-ties, and has for its object to improve the type of ties shown and described in my earlier Patents Nos. 685,213, of October 22, 1901, and 1,274,897, of August 6, 1918,

Both of my former patents show generally a flat rectangular top-plate havingdownturned end-portions, which practically close the opposite ends of the ties, and are relied upon mainly for preventing endwise creeping of the ties, and a central depending longitudinally arranged web. The later patent shows similar reinforcing strips, which are provided with depending V- shaped spurs, which co-operate in a limited way with the end-portions for anchoring the ties.

The'present invention has for its particuthereby greatly lessen the labor and cost of manufacture, by eliminating the down turned end-portions, which have been found to seriously interfere with the proper and effectual draining of the ties, and to provide a metal tie of the class, whose opposite ends are open and unobstructed. And a further object is to provide a number of relatively broad depending rectangular and transversely arranged lugs or spurs, which are disposed at regular intervals alongthe opposite lateral edges of the tie, for more effectually anchoring thetie throughout its length in the ballast or other support.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing, in which- Figure l is a top-plan view of thecom- -plete tie. Fig. 2 is a side elevation of the same. Fig. 3 is a bottom plan viewof the tie. Fig. 4 is an end elevation of the main body of the tie. Fig. 5 is a vertical crossseetion' taken on line 55 of Fig. 2. And :Fig. .6 is a detached lug-supporting strips.

. I ,In the drawing, 2 represents the normally edge view of one of the flat rectangular top-plate ofthe tie, which is perforated at 2 for securing the rail-supporting parts (not shown), and 2 represents a central longitudinally extending web which depends from the bottom or blade, side of the late 2, and whose length is substantlally t e same as the said plate. 33

represent similar metal reinforcing strips,

which are mounted at the opposite lateral under edgesof the plate 2, and which are rigidly held in place by rivets 3* which pass through corresponding perforations in the plate and strips. The strips 3-3 erably substantially the same length as the late 2, and from the underside of each strip .epend similar transversely registerlng lugs or spurs 3, all of which may be of the same size, but are preferably formed rectangular, so as to present a large number of relatively broad surfaces to the ballast or under-filling (not shown), in which the tie is embedded, for preventing the endwise creeping of the tie. The opposite ends of the tie are preferably open and free from any obstructions which might prevent the free and ready draining of the ballast beneath the tie.

Patented- Apr. 25, 192 2. a

are pref- By providing a large number of the relatlvely broad square-formed lugs 3", as shown, greater and more efficient anchorage is afforded; and 'by'disposing' said lugs at frequent intervals .along' the underside of the body2, greatly increases the anchorage, i

which in the present case is distributed more evenly throughout the length of the body 2, and tends to hold the tie immovably embedded in the ballast or filling.

The size, shape and frequency of the anchor lugs 3 are material features in the present case. By their provision, I am able to entirely eliminate the depending end-po I tions of my former patents, which notonly" reduces the amount of material and the cost of manufacture, but the more important functions of said end-portions are, entirely 7 taken care of bythe said-said lugs.

By omitting the depending end-portions referred to and disposing the principal 'anchoring-fmeans intermediate the endsof the plate 2-, farther removed from the usual,

adjacent sloping margins of the, road-bed effectually prevents the endwise creeping. of

the tie and the consequent loosening and crumbling'of the ballast and its relatively soft earthy support, V

Having thus described my invention, What I claim, is-

A railway cross-tie comprising, in its entirety, a T-sectionedobody having a deep,

' V 5 depending'web, a pair of narroW reinforcing strips rigidly secured to the horizontal portion of the body on opposite sides of the Web ORVILLE M. KNOX;v
