Application'flledJanuarj:29, 1918. semi No. 214.,350.

Tb dili'w hoin it my concern .Be' it known that I, ORVILLE M. KNOX; a- :citizen "of 1 the 'United States, .residing at.

Knoxboro -int-he county of Oneida and State f New Y0rk,, -ha-ve invented new and useful Improvements in Railway Cross-Ties, of. which the following is a specification.

This invention relates to the class of rail way cross-ties which are formed 'ofmetal,

and particularly to improvements in the type r of-tie shown in myprior Letters-Patent No. v 685,213,-dated October 22, 1901.

In my aforesaid patent I have shown a tie composed of a .top plate having downturne'd vertical end portions forminganchoring members, saidplate having a medial longitudinally extending web depending -centrall'y therefrom on the underside there- "cross. section and'p'rovided with transverse A of between said downturned ends of the plate,.thus forming a tie which is T-shape in "end anchoring po rtions'and a longitudinally extending central anchoring'portion.

The'prima'ry object of the present invention is to provide improved auxiliary means for strengthening and reinforcing the top plate on oppos'ite sides of the-longitudinally extending anchoring web, and for also reinforcing the do'wnturned end portions and at um same time providing additional means at the 'sides' of "the tie for more firmly and se curely; anchoring the same in the ballast.

A further object of the invention is to T provide supplementary reinforcing sand anchoring portions consisting of longitudinally extendin strips secured to the underside of the top plate adjacent tov the side edges thereof, and from end to end of said top plate between the vertical anchoring portions, sald strips being provided at intervalswlth depending anchoring spurs, whereby a tie of increased structural strength with greater anchoring efliciency is produced.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accom- P g ng, in which Figures 1, 2 and 3 are inverted perspective manufacturing the cross-tie, Fig. 3 also choring strips applied.

as set forth in my aforesaid Patent No.

685,213, I form a blank'(shown lof requisite length transversely from bar of rolled steel-or iron of T-shape in cross'sec tion, which bar may be of a length to form a plurality of said blanks therefrom. This blank is of a length exceeding that of the bed plate (Z of the cross-tie to'be formed,

orm ofbracing and an the'drawings) by cutting a section of ithe the. excess being nearly or quite equal to twice the depth of the vertical web a. a By means of fillings bb,'formed in the upper corners. of the sides of the web, said web' and bed plate are braced to maintain them transversely in their respective planes.

next removefrom each end of the webabout.

one-half of the aforesaid excessive length, which removal is ,readily accomplished by subjecting the end portio ns of the web to the 'shearlng or punching action of suitable dies in a press. The lines of cutting across the webare at right angles to-the bed plat-e d to'form vertical end walls on the web, the blank then presenting the appearance shown in Fig. 2 of the drawing. 1 next bend or depress the projecting ends cl d of the horizontal portion def the blank down'onto the vertical end facesvofthe web' a; as-shown in Fig. 3 of the drawing. Said depressed portions (Z' 03 thus form on the ends of the tie vertical 'abutments or anchoring members which arebraced'against inward pressure, and by their hold on the road bed they effectually prevent the cross-tie from being shifted endwise or laterally in-relat-ion to the track, and consequently maintain the track in line.

The top portion (Z constitutes the bed plate of the tie, which bed plate is maintained .in

v a uniform horizontal plane across'jthe entire width thereof to provide the cross-tiewith a bearmgqgf -max mum width-"and efiiciency upon theread bed and at the same time perhe dross-tie, and thus obviate the mit v free'esbfape of water from under the sides a) t liability -.'of entrapping water under the longitudinalside edges thereon; Each strip cross-:tie, such entrapped water tending to loosen the hold of the tie on the road bed. such entrapping of the water under the tie is als gu arded against by limiting the depth of th dwellsor abutments dd, so as to preven their projecting beneath the bottom of thewb! a. Furthermore, it will be observed thatthe horizontal bed plate (1, with the continuous single web a in the center thereof, afiords the most convenientaccess for thoroughly tampingthe", ballast under the tie from o posite sides thereof and unim y a thro c it the length of the tie.

. Inorder to more efiectually reinforceand brace the Plate I well as w sec'urea more reliable and eflicient hold upon the ballast, I provide. reinforcing or bracingstrips e, one-of saidstrips being 05 parallel with and adjacent to each of the i e, whi h may beof iron or steel, is secured to the plate d by'boltsor rivets e at eqnidistant points throughout the length thereof; whereb the longitudinal portions of the plate are materially strengthened and reinforcedand additional bracesare provided I to bear against the extremities of the Walls d d to prevent bending or deflection thereintervals with a row preferably V- haped and extend transversely of. a The strips e -are each provided at spaced or series of depending, ms or anchoring rejections f, extending wnwardl into t e plane of the lower e web a and end we These spurs or anchoring projections are of and" are cast integral with the strips 0,

but, if desired, asshown in Fig. 6, I may :provide reinforcing strips 0 having conical anchoring spurs -f- I riveted theretb, which construction may be integral therewith or used under some conditions of service. 7

It will also be evident that these strips will reinforce and strengthen the endwalls 03' ll. Itwill furthermore be evident that by the provision of the depending spurs upon the strips a more efiicient and reliable holding action of "the tie upon the ballast will be secured, and that, as these spurs are spaced a distance apart,

the free tamping of the ballast beneath the tie will be permitted, as well as the drain- The plate d is provided age on of all water.

with the squareor other angular openings 9 for the passage "of" bolts having similarly shaped heads and which fasten the rails to the tie. Y Havingthus fully described my invention,

A railway cross-tie comprising an oblong rectangularftie' plate, said plate having a vertical. web extending centrallyhnd Ion; the underside thereof, and aving downturned end portions resting against the ends of ,saidweb, reinforcing extending along the underside of the g3 terminallyagainst t e plate, and spaced reinforcing strips and extending transversely thereof.

In testimony whereof I aflix my signature. ORVILL I MARSHALL KNOX.
