This invention relates to improvements in temporary extensions for mine trackways.

The primary object of this invention is the provision of a practical type of temporary trackway extension, preferably used in mines where the trackway must be advanced slowly, as the wall of coal is removed, in-

cluding conventional lengths of rails of stock cross section which are inverted and connected' for slidable adjustment to the adjacent permanent rails of the trackway; special ties being used to brace the inverted tem-' porary track sections in a gauged andeiii- ClQIltrelation, with improved special he means to anchor'the temporary rails forslidable adjustment with respect to theends of permanent rails. I 1

Other objects and advantages of this in vention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a perspective view of the improved temporary track extension unit showing its relation to the end rails of a permanent track system.

Figure 2 is a view of the temporary track extension unit in a further adjusted position than that shown in Figure 1, and also showing, an improved type of car stop there- Figure 3 is a perspective view of a special tie used for detachable connection to inverted tracks, to hold a pair of the same in properly. gauged relation forwardly of the rails of the permanent track section.

Figure 4 is a perspective view of a special type of tie, showing clips used to hold the inverted temporary track extension rails to the permanently attached rails of a roadbed. Figure 5 is an enlarged fragmentary View, partly in section, showing the manner in which the anchor clips of the special tie of Figure 3 grip an invertedtemporary extension rail of the extension trackway system.

Figure 6 is a fragmentary view, partly in section, showing the relation in which the special tie of Figure 4 anchors theinverted temporary rails against the permanently attached rails of the'permanent trackway.

Figure 7 is a fragmentary view, partly 'in section, of the anchor clip and clamps at an end of special tie shown in Figure 4, the view 55. being taken substantiallyon the line 77 of Figure 5.

In the drawings, wherein for the purpose ofillustration is shown only a preferred embodiment of the invention, the letter A may 60. generally designate a permanent trackway, preferably of the mine type, whereon mine cars, or cutting or loading'machinery may pass, in approach to the coal wall which is being mined. In connection therewith the improved trackway extension unit B, of a temporary character, is used, in adjustably connected relation upon the rails of the permanent trackway A; being adjusted in the direction of the coal wall, as the coal is mined therefrom, for the purpose of facilitating approach of the cars and machinery thereto. i

lVithreferenceto the permanent trackway A, the same preferably comprises end rails 10 and 11, which are permanently attached on tie 11 of conventional character, which have usual clips l2-thereon, preferably at the inner and outer sides thereof, anchored to the base flanges at the inner and outer sides so of the web of the permanent rails 10 and 11, as can readily be understood. These ties 11 may be of the metal type, such as are usually employed in mines, and the use of the word permanent is restricted to the use that is applicable in connection with the laying of tracks inmines, where it is desired to provide a permanent trackway system, which is not permanent in the sense that the trackway and its details thereof cannot be removed, but is permanent in the sense that the rails and ties are used in their usual relation for transporting cars and other machinery thereover, and intended to remain in place until the supply of coal is depleted, or the trackway 95. is no longer of use. In this connection the extension unit B is used to designate an extension of the so-called permanent trackway system, which is temporary in character, inasmuch as it is used to adjust the trackway over the shortdistance between the ends of the permanent rails and 11 and the wall of 7 coal which is being mined or worked upon. Inasmuch as this distance is generally less thanthe length of conventional rail sections, the improved temporary trackway Bhas been foundvto efliciently fulfill all requirements under ractical conditions of use, I

In t e temporary 'trackway unit rail lengths and 16 are provided, which have exactly the same cross section-as the rail sections 10 and 11 above described as constituting part of the permanent trackway system, exceptthat they are inverted, In

other words,each of the rails 10, '11, 15' and 16 is provided with a foot portion 20,.aweb,

21,,and a head or ball'22, arranged according'tothe usual cross section of a car supmentioned,are inverted, and since they are porting rail; The foot 20 of coursehas the relatively thinfbaseflangesat each side of the foot and web .offthe adjacent rails, as

shown in Figure 6 of the drawings. The extension rails 15' and :16 lie at the outer sides of the permanent end rails 10 and 11, and it is to be noted that the feet .portionsorbases 201 ofitheinverted temporary rails '15,, and 16 lie close to the top surfaces of the heads of the permanent-rails 10 and 11,although in a'plan'ethereabove. Y i i I The extension unit 13' preferably includes the special tieand anchorclip constructions C for holding and-engaging the railexten: s'ions 15 and 'l6fto each other, forwardly beyondvthe ends of the permanent end rails 10 and 11. 'Each :tie, and anchor clip eon- .structi'on 'C preferably includes a metal tie body:10,although i-tmay be of other material if desired. .However,inasmuch as the device is principally used in mining, where all ties and rails'are placed more or less temporary,

' it ispreferredthat the metal type ofchannel tie body be used, such as shown at 10. It is not of unusual construction, except with reference to .the special anchor clips and clamps used thereon. At each end of the tie body 10 there is placed a permanently anchored or riveted holding or anchor clip rail and. the web of the invertedraih'along 30, and a pivoted locking lever or clamp 31.

. They are shaped and formed so as to engage the ball or headgof the inverted temporary the web preferably extending the height 1 thereof, almost to immediately adjacent the 1 base of, the inverted temporary rail,eand ref- 1 erence may be made to Figure 5 in this con- I nection. I

The anchor clips and 31 are so placed uponthe tie body 10 that the permanently attached clips 30 engage one of the tempor- V ary rails at the outer side and the other temporary rail atthe inner. side, andsiinilarly the pivoted anchor lever type of clips 31 engagethe extension rails, one of them at the inner side and the other at theiouterside. Asshown' for theti'es G of Figures 2 and 3,

the permanently attached clips 30 are placed to engage the temporary rail extensions 15 and 16at the inner and outer sides respectively, and the lever type of clips 31 engage the rail extensions 15 and 16 at the outer and inner sidesre spectively, I 1,, g

The anchor clips 30 alQjQf the type shown in Figures 5 and 7, each including a base portion 35of about the same width as the tie body,

10", and anchored thereto asrby a'pairof' rivets 36 and 37. The saidanchorjcli'ps 3Ov under sides of the normal head portion 22 of the invertedextension rail, and furthermore include theupwardly extendingweb engagingflangeor portion 39 adapted to extend throughout the major height of the rail web 21, for bracing and reinforcingthe inverted railin position. Thus, the-permanently ,at-- tached anchor clips each include. a body attached to the tie, and iportion 37 and 39 adapted tosnugly receive therein theinverted' ball or head'of the'rail and the web thereof. 7 Referring to the pivoted locking lever type of clip 31,'the same includes anjelongated' body 40, which is preferably narrowerethan the width of the'tiebody 10?, and anchored to one side of the medial axis of the tie body 10, by means of a rivet or other type of pivot connection42. This pivot connection 42 is pivoted eccentrically upon the body of the locking clip 31, to one side. of the medial center, line thereof, in orderto provide for a more efiicient rail attachment and detachment. 'jThis is bestshown in Figure 7 As shown in Figure 5'and elsewhere, the outer endof the body40 is upturned at 45 in acute angular relation, to-faoilitate engagement of a tool therewith for placing the pivoted anfurthermore includethe angleflangeportions 7 3T. adapted to engage thenormalj outenand.

chor clip in or out of rail engagement. 'At

its rail engaging end the anchor clip- 31 is provided with an upstanding normal web engaging shank or portion 47, which at the juncture with the body 40, is provided with an angled rail head or ball engaging portion 48, adapted to engage the sides and normal.

under-surface of the head 22fof the -rail, as shown in Figure 5 of the drawings; The web said web e ectivel-y throughout its height, and opposed to the web engaging portion 39 of theother anchor clip 30-. The web engag- 126 engaging shank 47: is of slightly less height thanthe hei ht of the Web 21, toengage the,

ing flange or shank 4,7 is convexly, arcuated at 50, at opposite corners thereof facing the web, to facilitate riding of engagement of the pivoted anchor clip 31 against the web of the rail, and to provide an efiicient connection, as can readily be understood. By making both of the corners 50 arcuate in this manner, it will be unnecessary to punch the body portion 40 at any particular side of its longitudinal axis, for receiving the pivot rivet or pin 42.

F romFigure 7 it will be noted that the pivoted anchor clip is placed upon the body 10 of the tie in such relation that one longitudinal edge thereof aligns with aside edge of the metal tie. r

' The arrangement of the anchor clips on the special tie C is shown in Figure 6, and for the rail extension 16 the permanently attached clip 30' engages at the outer side of said rail and the pivoted anchor clip 31 engages at the inner side or" said rail. Conversely, for the extension rail 15 the permanent anchor clip 30 engages at the inner side of said rail and the pivoted anchor clip or lever 31. engages at the outer side of said rail; the said clips engaging the inverted extension rails in the relation above described, and as is shown in Figure of the drawings.

As the extension rails 15 and 16 are slid along the permanent end rails and 11 of the trackway A, to extendthe rail system to the very wall from which coal is being mined, the special ties C are added, preferably on four-foot centers, as can be seen from Figures 1 and 2 of the drawings.

The special tie D shown in Figure a 01 the drawings is preferably applied to the rear ends of the extension rails and '16, where they overlap with the end rails 10 and 11 of the permanent traclzway system. This is shown in Figure 6 of the drawings, and the application is shown in the perspective views of Figures 1 and 2 of the drawings, wherein it is shown that this special tie D is applied to the overlapping permanent and extension rails just rearwardly of a permanent tie ll at the extreme ends of the end rails 10 and 11. As shown in Figure 6, the extension rails 15 and 16 are applied in inverted relation along the outer sides of the permanently placed rails 10 and 11, and at one end the tie body 10 of the tie construction D is applied with a permanently attached rail anchor clip 60, of the same nature and con struction as theanchor clips above described, having a plurality of rivets 61 which secure the same on the body 10 at one end of the tie, and having a relatively high web engaging shank 62 which engages throughout the height of the web 21 of the inverted rail 16, and at a juncture of the portion 62 with the body of the clip there is provided an angled head engaging portion 6- which engages the ball ot-the rail. No clips are provided for engaging the inner sides of either of the rails, but at its opposite end the tie body 10 is provided with a pivoted anchor clip or lever 66, which is eccentrically pivoted at 6? to the tie body 10 in the same relation as above described for the clip 31.

It possesses the same characteristics, having a tool enga shank 69 adapted to engage the web of the inverted rail substantially throughout the height thereof. It furthermore has the angled portion 70 adapted to engage the ball portion of the inverted rail; the same being convexel y arcuate at 72 to facilitate its placement, for loclrir g the rails together. It is readily observable that the improved special tie serves a very important function of preventing the rear ends of the extension rails from spreading with respect to the permanent end rails 10 and ll.

From the foregoing description of this invention it apparent that, an improved type of extension unit for track constructions has been provided, which will eliminate the usual expedients provided for track extensions, such as short rails and temporary wood rails, commonly called jumpers. Of course, while realizing that there have been suggested heretofore a number of rail extensions, such as by rearranging, and even inverting usual rai lengths, in the main they have been found unsatisfactory due to the manner in which they have been attached, and the spe' cial means for accomplishing such attachment. With the use of the special ties of my invention, 1 have provided an, improved track extension, 01 a temporary nature, which is extremely practical and recognizes all practical considerations in connection with the layin and extension of mine tracks. The device is one which may be readilyadjusted, easily applied, and quickly disconnected. It facilitates loading, saves time, and may be used to support cars to be loaded, loading mechanisms, and cutting mechanisms.

Various changes in the shape, siz and ar rangement of parts may be made to the form of invention vherein shown and described, without departing from the spirit of the in vention or the scope of the claims.
