The invention relates to rail oints. It has for its principal objects the provision of an improved jointof. the over-lapping type which eliminates the pounding characteris tic of the standard butt joint in which the line of joinder is at Tight angles to the lojngir tudinal center line of the ra l. The pur ose' q is to provide a joint of this ty'pe,'(1) w 'ch can be made at areasonable cost either by.

- standard joint, (3) which, can be used with standard, angle or splice bars, in which weakening of the web due to longitudinal splitting of the web of the rail is avoided, and in which a centralizing eifectis secured,

tending to keep the rail ends in alignment,

while at the same timeatfloiding any tendency of the wheel flanges to catch and ride up on the rail; One embodiment of the invention is illustrated 'in the 1 accompanying draw- I ings, whereilig'.

Figure 1 isa plan view of the joint withv out the angle or splice barsj Fig. 2 is a bottom plan View. F ig. 3 is a side elevation.

And Fig. 4 is a section on the line IV IV of Fig. 3, but with the splice or angle bars applied in order to show the type of bar pref- 39 erably used.

. Referring to the drawings, 1 and 2 are the ends of abutting rails. The'two rail ends 3 and'4 forming approximately a 60 degree V whose apexlies ust at the side of the web 6. The line 5 preferably departs about 20 degrees from a right angle with the longiof contact entends only through the rail The one rail end is thus provided shaped wedge ofthe other rail end fits. T he rail ends are secured together by any desired form of splice or angle bars7, 7 preferably of the cross section shown in Fig. 4, held ,by the usual bolts 8 extending through the holes 9, 9, two only of which are shown.

The ends of the'rails may be easily brought to the V-shape shown by sawing-along the lines Land 5 or may be formed at the rollsawing, or by the use of dies at the'mill," 'While the rail is red-hot, (2). which-has all. the elements of'strengthand safety of the" ingiihill while the rails are red hot by the use of suitable dies i -=.The inside of the rails which the flanges of thewheels engage is the one having the t5 soith'at' there is no moretendency of the eel to catch and ride up on the rails than acase in the standard butt joint in which "cut or'line of division-is at right angles to gthe'cjenterline of the rails. The slight angle giveiii'the cut 5 tendsIto centralize the two .railsi and' also to prevent relative. lateral ement between the rail ends, as such endsv mustnecessarlly move away from each other man endwise direction in order to permit of such; movement. When the ends are held,

(therefore, bythe splice bars, the rail endsa're much more I secure against relative lateral movement than .1s the case with the ordinary butt jointcon'struction.

Since the contactbetween the ends of the rails in the head followsthe line v3, there is I no opportunity for the Wheels to pound as they pass from one rail end to the next, so that the. wear and tear upon the rolling stock and rails is substantially reduced as compared 'With. a standard rail joint. At the same time thetongue at 1 0 (Fig. 1) is'unob# jectionable, since it is on the outside of the rail where 'it' is free from-the action of'the wheel flanges, which would tend to catch on the tongue, if it were located on the inner sideof the rail head. meet along the three lines 3, 4L and 5, the lines The joint-has-somewhat greater strength than the standard oint; can be made at only v joint; and has substantiallyincreasedWeartudinal center llIlQ'Of the ralls and this line ingqualities, due to the 'lack of pounding presentin the regularjoint and to the fact that the .V-interlock, with 'its centralizing tendency, relieves the splice bars and bolts of aconsiderablefdegree of strain. Other advantages of the structure willbe readily apparent to those skilled in the art. While the angle between. the lines 3 and 4 is preferably 7 about 60 degrees and that between the lines 3 and 5 is about degrees, it will be understood that the invention is not limited to these particular anglesas they may be varied with- I00 in reasonable limits and still give a oint having the utility heretofore pointed out.

lVhat I claim is: y

1. In a device of the class described, two abutting rails, one of which has a V-recess at its end with the side Walls thereof upright, and with the apex of the V terminating at the inner side of the web of the rail, and the other of which has a wedge at its end fitting said recess, the heads of the two ends at the apex of the Von the inner sides of the rails having their contacting surfaces lying at an an le approaching a right angle with respect to t 1e longitudinal center line of the rails.

I 2. In a device of the class described, two abutting rails, one of whichvhas a V-recess at its end with the side walls thereof upright, and with the apex of the V terminating at the inner side of the web of the rail, and the other of which has a Wedge at its end fitting said recess, the heads of the two ends at the apex of the V on the inner sides of the rails, having their contacting surfaces lying at an angle to the opposite side of the V-recess approximating a right an le. v

3. In a device of the class described, two abutting rails, one of which has a V-recess at its end with the sides thereof upright and approaching each other at an angle of approximately 60 degrees and with the apex of the V terminatin at the inner side of the web of the rail, and t e other of which has a wedge at its end fitting'said recess, the end of the wedge 1 which terminates in the head of the rail lying at an angle approximating degrees to the longitudinal center line of the rail and en ag ing a similarly inclined surface at the en of the V-recess.

In testimony whereof, I have hereunto subscribed my name this 30th day of November,

JOHN w..-BREWER.
