J. J. ROSS METAL MINE TIE Patented Aug. 19, 1924.

UNITED STATES J'US'IUS J. ROSS, OF HUNTINGTON, WEST VIRGINIA.

METAL MINE TIE.

Application tiled Maro11'19, 1924. Serial No. 700,351.

To @ZZ/,whom it may concern:

Be it known that I, JUsTUs J. Ross, a citizen of United States, residing at Huntington, in the county of Cabell and State of `West Virginia, have invented certain new and useful Improvements inL Metal Mine Ties, of which the following is a full, clear, and exact description.

The invention relates to metal ties which are particularly adapted for motor haulage in mines, and one of the objects of the invention is to provide a tie of this character which is extremely simple in construction and inexpensive in manufacture, and yet which is highly efficient in supporting and securing rails of various weights and sizes.

Another object of the invention is to provide a metallic tie equipped with an extremely. simple device which can be instantly operated to securely grip rails of various sizes, or rails which are worn or rusted away, and which is so constructed that the gauge will remain the same though rails of different size are employed.

A. further object of the invention is to provide a tie embodying the above and other features, and in addition thereto is so constructed that it will be securely anchored to the ground, or mine licor, in such manner that longitudinal or lateral movement of the tie will be prevented.

Further objects and advantages of the invention will be apparent` from the following detailed description, when taken in connection with the accompanying drawings; in which,

Figure l is a longitudinal vertical sectional view of one end of the tie.

Figure 2 is a plan view of the tie; a portion of the rail cap being broken away.

Figure 3 is a longitudinal vertical sectional view of one end of the tie, showing clamped in position a rail of smaller size than that illustrated in Figurel: and

Figure Lt is a longitudinal vertical sectional view of a complete tie.

Referring to the drawings more in detail, numeral l indicates the body of the tie which has a flat top surface and downturned side flange 2; that is, the body of the tie in cross-section, has the shape of ordinary channel iron. The flanges 2 strengthen the tie and in addition they function as an anchoring means to prevent lateral movement of the ties. As a further anchoring means, particularly for preventing longitudinal movement of the tie., I provide short sections of channel steel or iron positioned between the flanges Q'and riveted to the top of the tie; the anchoring channels being indicated by numeral 3. The channels 3 are of sufficient length to extend the full distance between the

downturned flanges

2, 2, of the tie so that there is no possibility of the anchoring means becoming displaced from its position as shown in the drawings, for if there should be only one rivet employed, the

flanges

2, 2, would prevent the rotation of the anchoring channel 3. It is to be noted that the

Idownturned flanges

4, 4 of the anchoring channel 3 extends below the lower edges of theI

downturned flanges

2, 2, so it is apparent that all of the flanges will cut into the ground or mine floor and thus prevent n'iovement of the tie in any direction. They anchoring channels are positioned on the tie directly below the rails, so that the weight of the rails will tend to force them in the ground; and further they strengthen those particular portions oit' the tie which directly support the rails. e Numeral 5 indicates a clamping lug which has a flat portion 6 coinciding with the flat surface of the tie, and an upwardly inclined portion 7 for engaging the flange of therail or the web of the rail as the case may be, depending on the size of rail employed. The clamping Vlug is provided with strengthening side flanges S, and the lug is preferably secured to the tie by means of rivets. rIlhe peculiar design of this clamping lug` and its novel manner of functioning to secure rails of various sizes without varying the gauge, will now be described.

In Figure l is shown in vertical section a relatively large rail clamped in position and a small rail in dotted outline; in Figure 2 is shown a plan view of a relatively large rail in clamped position; and in Figure 3 is shown in vertical section a small rail in Aclamped position.` By reference to these figures. in connection with the following I brief description, the design and operation of the clamping lugs will be clearly understood. l

The conventional rail consists of the head, welo, and flange, indicated respectively by the

numerals

9, 10, and l1, for the larger rail; and 9', 10', and 11', for the smaller rail. The clamping lug 5 is so designed that when it is employed in'connection with the if the inclined portion 7 of lug 6 was so designed that it was much shorter than illustrated herein, then when a small rail was used, its flange would rbe-forced under the -V lug until it contacted with the inclined porinclined member 7 tion at the point where the lug meets the surface ofl the tie, and consequently there wouldv be considerable variation in the gauge. As' -clearly illustrated in Figure 3, however, the clamping lug is not so designed, and by an inspection of that Figure it will be seen that when asmall ail is employed the web 10 abuts against the free end of the y By this construction the vertical center line ofthe rail is moved only slightly for different size rails, and this difference yin position just about coinpensates for the difference in the width of the heads of different rails. so that the gauge remains almostfexactly the same. I have described,A the lug in connection with large rails and vsmall rails, and vit will be understood that rails of intermediate'sizes will assume intermediate positions; the gauge remaining almost identically the same for all sizesof rails.l V y The cam wedge, indicated generally by niuneral 12, which is employed to engage the rail, forces it into engagement with the clamping lugy and securelylo'cks the rail in position, will now bedescribed. The cam wedge 12.is preferably of a general semi-circular shape, and has a flat central portion 13 resting onthe flat surface of the tie; the cam Wedge being lpivotally Iattached to the tie by meansof a loose rivet 14, or by equivalent means. v` As clearly shown in the drawings, thev cam ,wedge is eccentrically mounted on the rivet 14.

Extending upwardly and outwardly from :the flat: portion 13 is a gripping flange 15. This flange is shapedto fit the contour of the rail flange," and the Ipeculiar shape Aof the gripping flange will be apparentfrom an inspectionof Figure 1. The flange, as shownA at the left of Figure 1 is of greater length.y and is spaced farther fromthe surface ofthe tie than is the case with the flange shown on the right of Figure l1.y The flange von the left of yFigure 1 designed to conform to the contour of the flange ofthe largest rail to be employed,'and the flange on therightof' Figure 1 is designed to .con-

-formv torthecon,tour of the fiauge'of the smallest-rail to be employed. The length of.

the flangel. andthe distanceit is-'s iaced t, c t l Ifrom the vtie' surface, are gradually 4decreased from the maximum shown on the left of Figure 1, to the minimum shown on theright of Figure 1; and, of course, intermediate portions of the gripping flange correspond with the contour of intermediate size rails.

It will be noted that the gripping flange of lthe cani wedge is designed to contact with` the rail flange and with the rail web, for all sizes of rails, kso that it will force the rail into engagement with the clamping lug and hold the rail in a rigid and unyielding manner. f

The curvature of the edgeof the flat portion 13,*that is, the curvature of 'the edge of the cani which engages the edge of the rail flange, is on a'gradually increasing curvature from the left of Figure 1 to the right of .Figure 1, to provide for engagement with the edges of rail flanges olf various widths; and the curvature of the outer edge of the cam wedge is Vsuch that the distance between this edge andthe edge of the flat portion of the cam gradually decreases from the left/to right of Figure 1 to take care of the more narrow rail flanges ot the smaller rails. As previously mentioned herein, the cam wedge is eccentrically mounted on the rivet 141. v i

From the foregoing description it will be seen that the cam wedge is an inexpensive and highly eliicient device for quickly and firmly clamping rails of various sizes; it being only necessary to strike the semi-circular cam'with a hammer o r other tool to roy tate it into clamping position on yany size rail. J1nd when this camwedge is employed `in'conjunction with the particular clamping lug described herein, it will be apparent that rails of various sizes may be used withl out varying the gauge. l.

In accordance `with the patent statutes, I have described what l now believe to be the best embodiment of the inventiombut I do not wish toy be understood thereby as 'limit'- ing myself or the scope of the invention,` as many changes and `modifications' may be made withoutvdeparting from the spirit of the invention; all such I aim to include in the scope of' the appended claims:

Having fully .described the invention, what :[claim as new and desire to vsecure by 'Letters Patent is: v Y Y 1. A metallic cross tie, a fixed clamping lug tor engaging one side of the rail lla-nge,

lll)
