PATENT kMETAL MINE TIE.

To all 107mm t may concern.'

Be it known that I, JsTUs J. Ross, a-citizenl of' United States, residing at Huntington, in the county of Cabell and State of IVest Virginia, have invented certain new and useful Improvements in lifletal Mine Ties, of which the following is a full, clear, and exact description.

The invention relates to metal mine ties 1"," and one of'the objects of the invention is to provide a device of this character which is inexpensive in manufacture, and yet which possesses sufficient strength and durability 'to withstand theV severe usage to which it is subjectedj Another object' ofthe invention isto provide a tie which will securely clamp rails of various sizes without altering the gauge of the track.

material part of the present application is to provide a novel anchoringr means by which movement of the tie invany direction is prevented.

Further objects and advantagesk of the invention will be apparent from `the following detailed description whentaken inconnection with the accompanying drawings; in which, 30, Figure 1 is an elevational viewV ofthetie,

parts beingin section, and showing a section of a large railclamped in position, and also showing a small rail in dotted outline.

Figure 2 is a fragmentary plan view of the tie with a rail in position, an

Figure 3 is a detail perspective view of a portion of the tie with the anchoring means detached.

Referring to the drawings more in detail, numeral l indicates the body of the tie, which has a fiat top surface and downwardly extending flanges 2 on each side thereof; that is, the body of the tie has the cross-sectional shape of channel iron. These flanges possess a dual function, in that they add considerable strength to the tie and at the same time they act as an anchoring means to prevent any lateral movement of the tie.

The ends of the tie are turned upwardly and inwardly to form hook shaped ends as indicated by numeral 3; and wooden wedges 4C are inserted between the hooked ends and the rails to force the latter into place.

A novel form of clamping lug is indicated Another object of the invention forminga by numeraly 5. The specific `form of the clamping lug forms the subject-matter of a separate application, but its construction` and operation will be briefly described herein. In Figure l, I have shown in section relatively large rails clamped in position. and in dotted outline is shown a smallrail clamped in position. Rails are composed'of three parts, the head, the web, and the flange, and these partsare indicated by thenumer-l als 6, 7, and. 8, respectively'forthe large rails; andby. numerals 6', 77 and 8, respectively, for the small rails. The clamping lug 5 has a-flat portion-9 coinciding Vwitlithe flat surface of the tie, and an upwardlyinclined portion 10 for engaging the flange of the rail or the web of the rail as the casev may be, depending on the sizeof the rrail ein?y ployed. The clamping lug is prov-ided with: strengthening side flanges l1, and theA lug is.

preferably secured to the tie byy means of! rivets.

The clamping lug-5 is soL designed: that when it is employed with the largest rails commonly'used in minework, it will follow the contour of'thef rail iange or baseA 8, and thus exactlyA fix the positionl of the largest rails, as'clearly illustrated in'Figure'l. It will be noted, however, thatthe lug does not extend up to the web of the railwhen the larger rail is employed. If the inclinedfpo-rtion of the clamping lug lextendedl up to the web when large rails were employed, then it would be obvious that when smaller rails were employed the inclined portion would also strike the web and hold both the small and large rails in the same position, thus altering the gauge of the track. On the other hand, if the inclined portion was so designed that it was much shorter than illustrated herein, then when a small rail was used, its iiange would be forced under the lug until it contacted with the inclined portion at the point where the lug meets' the surface of the tie, and consequently there would be considerable variation in the gauge. The clamping lug is not so designed, however, and by an inspection of Figure 1 it will be seen that when a small rail is em-` ployed the web 7 abuts against the free end of the inclined member, and when a large rail is employed the web does not contact with the inclined member at all, but the flange of the larger rail contacts with the inclined member at the point where the lug meets the surface of the tie. By this construction the vertical center line of the'rail is moved only slightly `for different size rails, andtliis difference in position just about compensates' for the difference in width of the heads of different size rails, so that the gauge remains almost exactly the same. 1

As previously mentioned herein, the side flanges 2, 2, of the tie body, in addition to strengthening the tie, also serve as an anchoring meansto prevent lateral displacement.y One of the material features of the present invention is 4to provide additional means to prevent longitudinal displacement of the ities. Attached to the tie, preferably below each ofthe rails, is a. novel form of anchoring means, as indicated by numeral l2. rIhe anchoring means comprises a shortnietal strip having a flat surface 13 adapted to coincide with the bottomof the tie, and downwardly extending side flanges 14 adapted to dig into the ground or mine floor and prevent longitudinal movement of the tie. It will be noted that the flanges 14, 14; of the anchoring means are of greater length thanlthe flanges 2, 2 of the tie body, so that the flanges 14;, 14, will first dig into the mine floor, and will be followed by the flanges 2, 2. It will also be noted that the channel iron section constituting the longitudinal anchoring means is preferably yof a length equal to the distance between vthe flanges 2, 2 of the tie. It is apparent that if the member 12 extends from flange to flange of the tie, that it will be easily and securely held in place, for it is obvious that any rotation of the anchoring means would be impossible even ifonly one rivet should be employed. v v l vIt isbelieved that the construction and have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myself oi the scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention; allsuch I aim to include in the scope of the appended claims.

rHaving fully described the invention, what I claim as new and desire to secure by Letters Patent is: l

l. A metal cross tie, the body of said tie having the cross-sectional shape of channel iron, anchoring means attached to the bottom of the tie, said anchoring means having the cross-sectional shape of channel iron.

2. A metal cross tie, the body of said tie having the cross-sectional shape of lchannel iron, anchoring means attached to the bottom of the tie, said anchoring means having the cross-sectional shape of channel iron, and said anchoring means Vextending below the bottom of .said tie.

A .metal cross tie, longitudinally extending down-turned flanges on said tie, hooked ends formedon said tie, rail clamping lugs mounted on the tie, wooden wedges adapted to be inserted between the rails and i the hooked ends of the tie, anchoring means extending between the downturned flanges, said anchoring means having the cross-sectional shapeof channel iron and the downwardly extending flanges thereof beingl greater depth than the first-mentioned flanges and arranged substantially at right angles thereto.V 1
