i present-invention has reference to *a track construction for-mlnes, and-my ;pr1- ma-ry ObJ'fiCl? is the construction and arrangelrnent of parts wherebythera-i'ls in a mine amay be ektended by the employment of supplemental rails without interferin pernianent'rai-ls,ofthe track. o I v A further object-"is the p rovisionin a construction of this type of means for efi'ectiveg with the -1o' ly end-{securely clamping the main rails on the ties, a nd such means ibe'ingl also utilized fifor supporting extension rails which are -ro- *tated to ari-gh-t angle withrespect to the main=--ra ilsrso that {the wheels, oft-he mine cars eaiitravelf-ofl' of the main railsand onto the-fwebs 'dfithe extensionrails when thetrack is to be temporarily extended, regardless of pro-j ections of the ends-ofthemainrai-ls.

To the, attainment A of {the foregoing and other' ob'jects which willpresent themselves as the nature of :the inventionfi's better nnderstood, the improvement-also resides in certain"-other novel features of construction, combination and operative association of parts, a satisfactory embodiment of which -is-disclosed y the accompanying drawings.

the tie andfholding two "positions. 3

Figure -8 is a sectional view approximately on the'line 8."8 of Figure .7.

As the description progresses it will be noted that either the-main rails .or the extension rails may be easily, quickly .and'secure'ly clamped to-theties. I

JThe ties are of the :usual channeled metal the clamp in either offits members and are indicated by the numeral l. @n each of'the'ties, adjacent to :the ends thereof there are fixed transversely arranged blocks 2. For the sake of convenience I-will refer to these blocks as filler blocks. The blocks have their inner faces straight and are 65 notched'in a line with the lower edges, asindieated by thenumeral 3. The upper walls provided by these notches are inclined, and the notches are designed to normally receive ofthe track. The second edge of the base flange 4 of the rails 5 is adapted to be engagedbythe notched ends6 ofplates 7 which 'I will refer to as clips. As-stated, the'bloc'ks '2 are firmly riveted to the ties but the plates "7 are pivotally secured to the said ties,ras;i-n-

dicated by the numerals 8. Suitable means, suchas either fi-Xed or removable pivots 9,

hold the Clipsloiigitudihally on the ties and $0 the lips '6 thereof in firm engagement with :the-inner base flanges-of (the rails 5.

Except for the inner straight face, the spacer blocks -2 (which are of a length corresponding approximately With that of the Width of :the :tie) have their upper and outer faces shaped to correspond with the shape of the fishing spacevof a raihand Whenthe track -iszto be extended, such rails indicated by'the inumera'l '10 and arranged right-angularly with respect to :the rails .5, and having their heads received in the outer fishingspaces of the said rails5, rest upon the blocks 2 and-have-one of the edges of their base fianges resting on the :tie. l Irn this instance thepivot pins -9 for the clips areiremoved andthe cl ips are'swung'toa position reverse to that previously described. :By reference to the drawings it will be seen that the pivotBisdisposedcloseto 'thera'il engaging ilip *6 of *the clip 7, and by reference especially to Figure 4 of the drawings it will be seen that when the clip is reversed the sec- 0nd and non-notched end of the clip will be Figures 1, 2, 3 and 4 'of the drawings, to be brought over the upper edge of the base flange of the extension rail 10. The pivot 8 and the pivot 12 are each preferably inthe nature of doubleheaded rivets and the base 13 of the ,swingable base flange engaging clamp for the rail'10 is held in such engagement by a removable pin 16.

i Obviously in lieu of the locking pins 9 and 16, of theblocks orclips7 and the base flanges of thevangle clamps may be in the natureof lugs orstubs movable into depressions in the upper face of the tie, and when the swingable clamp 14 is not employed and the same is arranged transversely of the tie, as disclosed by Figure 5 of the drawings, either the vpin 16 or the lugs are again brought into engagement with the tie to hold the said clamps in such position.

By reference to Figure 1 of the drawings it will beseen that the extension rails may-be.

connected to the permanent rails regardless of the dlfference between the projectlng ends of the said main rails. The construction is extremely simple and may be easily operated to firmly secure both the main and the extension rails on the ties and will permit of the easy and quick removal of such rails from the ties While I have herein set forth a satisfactory embodiment of my improved device, my features of Invent on are capable of extended application and, therefore, I do notwish to I be restricted to the precise details herein set forth and, therefore, holdmyself entitled to 1. Ina mine track, metal ties upon which fixed rails rest, notched blocks fixed on the ties for receiving the inner base flanges of the rails in the notches thereof and the webs of the rails being disposed away fromthe notched edges of the blocks, plates comprising rail engaging clips having, one of their edges notched to receive the outer base flanges of the rails therein and being pivoted to the ties in close proximity to said notches, the blocks designed to provide rests for the webs of extension rails,'when the latter are turned to a right angle and arranged thereover, the heads of the extension rails, when so positioned being receivedin'the fishing spaces of the fixed rails, clamps on the ties forengaging with the base flanges ofthe extension rails for holding the same on the blocks, and'said clips when turned on their pivots end for end dey signed to provide rests for the heads ofthe extension rails atthe portions thereof received on the ties beyond the ends of the fixed rails.

2. In a mine track, metal ties uponwhich fixed rails rest, notched blocks fixed on the ties'for receiving the inner base flanges of rails in the notches thereof and having their inner edges spaced away from the'webs of the rails, plateslcomprising rail engaging clips having one of their edges notched to; receive t we outer baseflanges 'of the rails therein and being pivoted to the ties in. close proximity to said notches, the bloeksdesigned to provide rests for the webs of extension rails, when the latter are turned to a right angle and arranged a V thereover, the heads. of the etxension rails,

make such changes therefrom as fairly fall within-the scope of what Iclaim.

While I have-referred to the holding means for the clamps and clips as being in the nature of removable pins, it will be apparent and as disclosed by Figures 7 and 8 of the drawings that the baseof either the clamp or clip maybe formed with a depending teats17 and the top of thetieisformedwith depressions r for sockets v18 to receive the teats therein;

IVith this arrangement it will be necessary I that an impact of force, such as a blow from a hammer, be directed against one'side of the clamp or clipfor moving the same toeither of its operative positions or for holdingthe same outofoperative position.

Having described the invention, I'claim
