Appiieauon eigenaren e,

the present invention will undoubtedly prevent many accidents 4to trainswhich now take-place due to the spreading and Vcreeping of rails. Certain novel specific features vand combinations oit' parts will be fully set. out as the description proceedsherein, which go to make the present invention a valuableone for the purpose intended and above mentioned. I am aware that many devices of the kind under consideration have been invented, butit is thought that my invention presentsavery complete type of structure for'the purpose, possessing a result ofa combination of several features introduced therein', a practicaland commercial'utility not found in many of the similar devices at present used for alike purpose.

In the accompanying drawingsI forming part ofA this speciti'cation I have shown one complete example of the physical embodi- Vment ot my invention, with some slight` modifications, constructed according tothe vbest mode I have so-far' devised for'the 'practical application of the principles of my invention.

Figure 9 is a Vperspective view of a slightly modified form of' casting-similar to Figure 8 on line '10-1O of Figure 11 of a type of Yfasteningused at rail Joints.

i YFigure 11 is a plan view of Figure 10.

ln the drawings the numeral 1 indicates the ordinary l'-rail with the exception ot certain raised proiections 2, 3, 4C, 5, formed `preferably integralwiththeweb 12 ot said rail, the intention being to roll the rails with the raised projections, either in alternate positions such as showny at 4L, and 5, of Figure 5, or in opposed positions such as 2,- 3 iny l said Figure, as will bej explained below. v`The size of these Vprojections is clearly illustrated in Figures 1, 2 and 3 of the drawings.

The rail 1 is mounted in the shaped casting 6,- the vform otwhich is seen to advantage in Figure 6, having a base portion 7, preferably beveled on its lower tace 8, so as to act with the complementary shaped plate 9, as shown in Figurel. There are'also two upstanding legs'10,and 11 shaped as shown to Aconform on the shaped plate 6. rBetween the legs is .therecess 14C, adapted to accommodate there- 9 as' shown.

lThe shaped plate 9 is best illustrated in the Figure .7 of the drawings, and has a base i 20,having. a lower face 21, which in normal Figure 1 is a side elevation of. a portion positionas in Figure 1 isparallel with'the tie 1T and the upper tace 31 of said plate 9 isibeveled complementary to the beveled enable a firm grip to be taken on the flanges L 13,"and 22 o-t'herail 1, by the bent portions oi" the shaped plates and hold thera-il se".

and 27 may both be omitted, and the shoulder 24C on plate 9 is then placed in engagement with a channel formed in the tie itself.v

The lag-screws 2 3, 23, etc., it will be noted have preferably triangular heads, so that ,the same cannot-.be tampered with readlywhen an ordinary wrench-is used, thus obviating the likelihood of unauthorized persons loosening said 'lag-screws.- `The holes in Ywhich thelag-screws are placed Vare preferably bored holes of proper size, and said holes are preferably creosoted or' treated so that the bored threads of the same donot readily decay, and consequently the lag-screws hold into the tie firmly for a long period of time.

yThe bossed portions 2,3, etc., it is evident when in normal position engage ubetween the upstanding legs of the shaped plates Sand l9, and the rail l is .thus prevented from creeping longitudinallyalong the ties. As

before mentionedtlie raised projections on the rail may be either alternately positioned Vas 1l, and 5 or opposite ,each other as 2 and 3. l/Vhen in alternate position it is evident that the recesses 1 4 `and 28 `in the plates 6 and 9 are omitted to suit the conditionv and the upstanding legs 10, 1l, and 29, 30 .of

the plates 6 and 9-become continuous, and

adapted to fit against the web and ianges` of the rail l when there is no raised projection on the side of `the rail nearest to said plates respectively.

'This type of lanti-creeping and: anti-rail Vspreading fastening is adapted for use on straight tracks and on curved, but atten-v tion is called tothe fact that when `used on curves, the plate 6 is usually .placed on-the inner side of the curve, as the shaped plate 9, being in immediate contact with the tie, the rail is held more rigidly, and so makes the fastening as a whole more secure. It is also apparent that' in some cases it may `be vfound 'advantageous to use two or three ordinary spiked fastenings on" ties which `are placed intermediate of those ties which carry the type of fastening illustrated in the present invention, and in this way reduce the number of my fastenings rused "pe'r raillength. This reduces the number of raised bos'lses or projections 2, 3, etc., necessary per rai While' vI( have shown the raised .proj actions formed integral with the .rail web,`.andipreferably formed on the rail by rolling when therail is manufactured, it is also evident that the bosses or projections may be added. to old rails to accomplish the saine purpose, to wit to engage the upstanding legs l0, 1l, 29, 30 of the plates 6 and 9. ln the Figures 10 and 11 ofthe drawings is shown a device for use with my invention at the joints of rails. 32.indicates amodiication of plate 6, while 33 indicates a modification of plate 9. Theplate 32is used especially on curves for supporting the outside of the rail, while plate 33 is used as a mate tothe same 'on the inside or inner side of therail. vIt is evident that `the use of these plates obviates .the necessity ofbolts at they rail joints when .the type of fastening shown `in Figures i .and 2 is .used throughout the length of the rails, on the ties which support saidrails, other than those near the joint.
