The present invention relates to an "improved rail tie, which is especially, although notnecessarily designed for use i in. the construction of steelniine tracks, such as are i '5 employed in coal;niines and other zindustrlal The main purpose of the invention 13110 provide simple and inexpensiveallg metal 7 tie, such as will facilitate assembllng and 10 laying of tracks, and which is such as to hold the tracks in proper alignment under all conditions.

The invention is characterized by many important features. For instance, .it is made of one solid piece of steel, has a double strength wedge backing, embodies no clips,

nuts, bolts, rivets, or other fastening catches to work loose and includes no spikes or splice bars such as are ordinarily used. The 1nvention is advantageous, in that the work man needs nothing except regular tools to lay the track. The invention permits a jumper or extensionrail to be ;used, and keeps the track up to the face. It main- 5 tains the tracks in true gage, saves much head room, is very easyto handle, and thev track can be laidquickly. It can be'used time and time again.

The added wedge strength, and no clips, nuts and bolts or other fastenings increases the life of the ties in comparison to other steel ties ofthe same character. Inasmuch as the device is in one piece, no extra parts are required.

The invention will reduce operating and maintenance cost and is advantageous in that it can be employed with any sized steel rail, ranging from twelve to thirty pounds. Other features and advantages accompany the invention, and these will become apparent from the following detailed description x and drawings:

Figure 8 is a fragmentary detail sectional and elevatio'nal view, showing how ajumper or extension rail can be used, in order to keep the track up to the face.

i In carrying out the invention I employ a shaped in cross section. The opposite. ends 1 thereofr are directed upwardly," ,as at -2-,-' :to V

The curvature of 2 the hook, in each instance is such as to ac- 'commodate the curved sideitof a driven retaining Wedge 5. The opposite 'fa'ce 'ofthe wedge, however, is fiat, in. order to bear;

against the flat surface of the web of the" rail; As a-matter of fact, the wedge is shaped throughout'to conform to the surfaces of the tie and the rail.

hookand then being directed inwardly as at f 7, and terminating in a smallerbase, flange" engaging hook 8 This extension is of 'a' yielda'ble 'nature,}andit' is obvious that the, tighter the wedge is driven the firmer the clamping action of the hook 8.

referring to Figure 3,, 't will be ob served that the extension rail, in each in-: stance, :isclearly interposed between the'web of the main rail and the'hooked end of the special tie, the same beingheldin place by a relatively small wedge which is drivenin I betweenthe base flange of the complementa-l' I rail and the extension strap of the tiej. vIt

is of coursequite common to employ these' supplemental extension rails in practice, and 1' the only change requiredwhen used with the improved tie is the em loyment of smaller wedges. I

The invention 1s of such simple nature that the construction'and methodjof application and use is quite clear. For this reas son, a more lengthy description is believed], I

to be unnecessar Minor changes in'the size}. shape and proportion-s, comingwithin the scope of the inventionpclaimed, may beresortedvtp desired.
