RAILROAD TRACK.

Application filed January 16, 1926. Serial No. 81,758.

This invention relates to means for removably securing railroad rails to metal ties and is a modification of, or improvement on the inventions of my prior patents, Re. 16,023 and 1.516,085, and of my Patents Nos. 1,589,790, granted June 22, 1926, and 1,585,964, granted May 25, 1926.

One of its objects is to provide an all metal track in which the rails are held to the ties with absolute security against displacement in vertical or horizontal directions without any drilling or cutting of the ties being required, and another object is to pro vide a retainer bar for use on such track, which is light in weight and consequently inexpensive, and which adapts itself to varying heights of the rail flange top surfaces and has certain other advantages.

There exists a demand in certain places for an all metal track which is positively immovable, that is to say, in which the rails cannot be displaced laterally in either direction and cannot lift from the ties even under the very severe loads to which they modern electric or steam locomotives. To meet this demand, I have modified the arrangement of securing means covered in my Patent No. 1,589,790, aforesaid, by reversing, on certain of the ties, the relative position of the permanently secured, or-

welded-on abutments and of the bolted-on retainer bars, so that one of the latter is located on the outside of the rail on an occasional tie, for example, one out of every three or four, the welded-on abutment being on the inside of the rail on those particular ties. On curves where the lateral thrust is all towards the outside rail, each tie will preferably have the permanent abutment on the outside, but on straight stretches of track, where there exists a tendency to displace the rail laterally in either direction, and where the wave action, induced in the rails by the wheels, sometimes tends to lift the rails from the ties, I obviate the possibility of any movement of the rails by the present arrangement.

In my Patent No. 1,516,085, I have disclosed and claimed a retainer bar having its ends bent around to form eyes for the securing bolts, said ends being given a slight spiral twist, whereby they act like lock washers to prevent loosening of the nuts,

The invention is illustrated in the acconi-,

panying drawing, in which,

Figure 1 is a plan view of a track equipped with the new arrangement of rail-securing means.

Figure 2 is a section of a rail secured to a tie by my improved retainer bar.

Figure 3 is an elevation looking towards the left side of Figure 2. I

Figure 4 is a plan view of the retainer bar.

Figure 5 is an end view of the same before it is clamped in place, and

Figure 6 is an elevation of said bar ready for use.

In these views, the ties 1, of rolled T-section, have the bulges 2 on the lower side of their heads, as in my Patent No. 1,516,085, aforesaid, and are preferably provided with anchoring and stabilizing angle-plates at their ends, indicated at 10 in Fig. 1 and which form the subject matter of an application filed December 28, 1925, Serial No. 78,061, as a division of Serial No. 34,021, now Patent No. 1,589,790, aforesaid.

The rails 9 laid on these ties, engage, on one or the other side, the abutments 3, which are welded, or otherwise permanently secured, to the ties, as indicated at 4, and which present a plane vertical face 5 to the edge of the rail flange. Opposite each of these permanent abutments, the rails are held to the ties by the retainer-bars 6, secured by the bolts 7, passed through holes 17 in the ends of the bars and having hook-shaped heads 8, engaging around said bulges 2, as in Patent 1,516,085. I will now describe the retainer bar in detail. It consists of a rolled section, of channel shape for the sake of lightness, with its inner leg 11, which engages the rail flange, slightly shorter than its outer leg 12, and with a central lateral. projection 13, having its lower surface inclined to fit over the rail flange, as shown in Figures 1 and 2. The end of the leg 12 is the only part of the bar which rests on the tie and constitutes a fulcrum about which the bar can swing, so that the projection 13 can accommodate itself to rail flanges of different heights. The bar could be solid instead of channel-shaped, in which case its lower surface would be inclined so as only to contact the tie at its outer corner, but this would make the bars unnecessarilyheavy and expensive.

In some cases I "form, as by hammering, a sharp prong or lip 14; in the center-of the bottom of the leg 12, as shown in Figs. 2, 3, 5 and (3, which can be driven into the tie to ensure against any displacement of the bar by side thrust on the rail. It will be obvious, however, that there is not much danger of such displacement, especially with thealternate arrangement of the retainers, shownin Fig. l, but said biting prong or lip forms an additional sateguardanddoes not add materially to the cost.

A diagonal or inclined saw-cut 15 is niade in'each end of the bar, running through to the adjacent bolt hole 17, and one of the portions thus severed is bent up, as at 16, to constitute a check-to prevent the nuts 18 from jarring :loose. In other words, .said bent up portions act like lock washers to resist unscrewing of tie nuts. Finally, the bar is given a slight longitudinal camber, as shown in Fig. 6, whereby, when it is clamped down by the bolts 7, it is caused to hug the tie very tightly and its springelike tendency to return to its original shapealso assists in holding the nuts against'turning.

'lVhile l have shown in v.Figure 1:two ties with the permanent abutment on theoutside and two with the same on the inside, it will be understood that the arrangement may be varied and that, usually, the .number of permanent abutments on the inside will be less than the number on the outside. Also, as far as this part of my invention is concerned, theremovable overlapping "tastener may beot any suitableconstruction.

Where I use the term welded in the foregoing and :in the claims, it :is to be understood as meaning permanently se cured.

Having thus described my invention, what I claim is:

l. .A railroad track, comprising .-1netal ties,

vertical faced abutments welded to some of the ties to engage the outside edge of the rail flange, similar abutments welded to the other ties to engage the inside edge of the rail flange, whereby at the same ends of successive ties-the abutments are staggered relativelyto each :other, retainer bars shaped to overlap the rail flange opposite each of said abutments, .and removable means to clamp said bars to .the ties.

2. A railroadtrack,comprising.metal ties, vertical-faced abutments welded thereto, so as to abut the ,rail fianges on the outside on certain ties .and so as ":to :abut the mail flanges on the insideonathe other'ties, where by at :the :same ends (it-successive ties the abutments are staggered relatively :to :each other, overlapping retainer bars to engage the rail flanges opposite some "abutments, and hookbolt-s engaging vsaid .ties :and passing through z'holesin said'bars :to secure (the latterito the ties.

3. :Means to secure rails *to ties, comprising-a bar of greater length .thansthe width of the *tie and having holes in its 8116.5, a central lateralgprojectionon said=.bar=to:overlap :the rail flange, said :bar ,being' so :shaped that it :rests on ithe tie at its :outer corner only, and .bolts -passed zthrough 1 said holes to securesthecbar to the tie, saidlbar'hatiingiupwardly projecting lips :integral with :the bar to;act as loek nuts.

4. Means ato secure zrails .to anetal zties, comprising "a ibar of inverted channel section with itsiouter legilonger than its inner leg, having :holes in :its ends ifor clamping bolts. and acentral la'teral projection to overlap the .rail flange, and'the lower edge of said outer :leg having .a :projection adapted :to

bite finto :the .tie.

In testimony whereof :I havehereunto set my hand.
