RAIL JOINT.
' Application filed February 1925. Serial No; 252,844. a A
This invention relates to certain new and useful improvements in rail joints and particularly to a oint of the scarf type wherein the meeting rail ends are of twin formation and are capable of assembly by movement in either longitudinal or lateral directions.
With the above and other objects in view,
that willbecome apparent as thenature of the invention is better understood, the same consists in the novel form, combination and arrangement of-parts here nafter more fully described, shown in the accompanying drawing and claimed.
In the accompanying drawing, wherein like reference characters indicate corresponding parts throughout the several views, 7
, Figure 1 is a fragmentary top plan view showing a railroad track construction with the meeting rail ends equipped with the improved joint connection;
Figure 2 is a fragmentary side elevational View showing the meeting rail ends secured together by stud bolts with the usual fish plates and splice bars eliminated;
line 33 of- F igure 2 showing the overlap ping rail ends; v c
Figure 4 is a cross sectional view taken on line 44 of Figure 2 showing the lug ofone a rail end anchored to the adjacent rail end; and c Figure 5 is a fragmentary perspective view of one of the twin rail ends.
As shown in Figures 1 and 2, the rails 1 are supported upon cross ties 2, the meeting joined rail ends being of the scarf type with the overlapped portions'of the rail ends sup ported upon a cross tie and being secured together by bolts 3 extending through the overlapping web portions of the rail ends with the elimination ofv the usual 'fish plates and splice bars. ,c I c The meeting rail ends are of the scarf type and of twin construction, each rail end being longitudinally cut away upon one side there of on a vertical line midway the opposite sides of the'rail as clearly shown in Figures 3 and 5. The rail comprising the usual tread 4, web 5 and base flanges 6 has an end end thereof inIline with the tread section 4 Figure 3 is a cross-sectional View taken on y extension resulting from the cut away por-' and spaced below the upper face thereof to be received in a notch or recess formed'in the tread section 4: of the meeting rail end. The
tread section 4' of the rail; has a recess 8 formed in the end thereof adjacent the rail extension 'at'the lower side of the tread below the upper face thereof. Theseating of d the lug projections 7 in the recesses 8 is shown'niore clearly in Figures 2 and 4: and
when so disposed a screw bolt 9 is passed upwardly through an opening 10 formed in the lug 7 to be received in a threaded opening formed in the top wall of the. recess 8. As i 11 to eliminate the presence of abrupt shoulders or sharp corners at the meeting portions ofthe rail tread, to eliminate chipping and cracking of the abutting end faces. With the rail ends so engaged, relative vertical movement ofthe rail ends is prevented'by the projecting lugs 7 on one rail end engaging in the recess 8 on, theother rail end, the
overlapping web sections 5 being bolted together as at 3 while the rails including the scarf joint portions thereof are secured in any suitable manner to the cross ties 2.
the preferred embodiment of the present in While there is herein shown and described vention, it is nevertheless to be understood that m nor changes may be made therein without departing from the spirit. and scope of the inventionas claimed.
WV hat we claim as new is 1. In a rail joint of the scarf type, apair of meeting rail ends of twin construction assembled 'by either longitudinal or lateral movement, each rail end being cut away at one side upon a central vertical plane forming an end extension, interfitting connections betweenthe ends of the railextensions and adjacent rail ends, connecting bolts for the rail ends passing through the overlapped webportions of the rail extensions, the, interfitting' connections comprising a lug on the end of the rail extension and a recess in the end of the rail head facing the cut away side,
and screw bolts for anchoring the lugs in the recess. 1 c
2. In a rail joint of the scarf type, a pair of meeting rail ends of twin construction as- 'one' side upon a central vertical plane formweb portions of the rail extensions, the interfitting connections comprising a lug on the end of the rail extension and a recess inthe end of the rail head facing the cut away side,
screw bolts for anchoring the lugs in the re cess, and the end of the tread portion of the 10 rail extension and the end of the tread portion facing the cut away side being rounded to eliminate cracking of the meeting ends of the rails.
In testimony "whereof we aflix our signs.- 15 'tures.
