N.,*C`zechoslovakia> Application May 23, 1936, Serial No. 81,342 In Czechoslovakia July 23, 1934 ‘ 6 Claims. (Cl. 23S-219) This invention is for improvements in or re In the drawings, lating to joint connections of permanent way Figure 1 represents rails. Rail joint connections are kno-wn comprising, 5 for insertion in the joint, a transversely movable wedge-shaped member which is kept in contin uous contact with the ends of the rails on either side of the joint by spring urging means, the wedge-shaped member being formed at at least 10 one end with a substantially vertically disposed wedging surface arranged slidingly to abut a cor respondingly shaped and disposed wedging sur* face on the adjacent rail end. The invention relates to rail joint connections 15 of this class (hereinafter referred to as the class specified) and comprises an improved construc tion as will hereinafter appear. The invention consists in the provision of a rail joint connection of the class above speci 20 iied comprising in combination with the wedge a horizontal section through the rail joint connection taken along the line of the connecting bolts which connect the parts of the joint together; 5 Figure 2 is a plan View of the connection; Figure 3 is a side elevation partly in section of the connection; Figures 4, 5 and 6 are respectively cross-sec tions through the connection on the section lines 10 IV--IV, V-V and VI-VI of Figure l, these iig ures and the preceding Figures 1 to 3 showing the parts of the invention according to one of the embodiments thereof; Figures '7, 8 and 9 are respectively a horizontal 1» sectionjplan view and elevation similar to Fig ures 1, 2- and 3, but showing the parts of the invention according to the second embodiment thereof, and -Figure 10 is a cross-section through the con shaped member of the connection, a supporting nection on the line X-X of FigureV 8. 20 member therefor arranged to be inserted be Referring first to the embodiment of the in tween the rail ends on either side of the joint, vention shown in Figures l to 6, the- two rails a sleeper plate, means to aiiîx the supporting on either side _respectively of the joint are cut 25 member to the sleeper plate, the sleeper plate out at the joint in wedge-shape on two verti~ .t being common to both the supporting member cal planes symmetrical to each other. The ends at at least one end thereof and the adjacent .|, 2 of the rails rest on a common supporting rail end, and fish plates for connecting the sup plate 3 ñxed on the sleepers and on which they porting member to the rail ends. are fixed at a certain distance from each other. According to a preferred form of the inven 30 The intermediate space between the two rail ends o tion, the supporting member for the wedge l, 2 is ñlled up, leaving expansion gaps, by a shaped member is a bar of inverted-T section wedge-shaped bar 4 of inverted-T section rest which is clamped down by its ñanges on to the ing by its flanges upon the face of the support sleeper plate. It is frequently the case that in parts of the ing plate 3. -The web of this bar 4 is thicker track rails of unequal length abut together. In than the webs of the rails and is provided with ~ longitudinally extending ribs. The bar 4 is firm this case the heat expansions and contractions ly connectedby rivets or bolts 5 with ñsh plates on the two sides of the joint are unequal.. The shorter rail does not vary its length to the same 6, which are also formed with longitudinally ex extent for a given temperature variation as the tending ribs as shown and which by these >ribs engage the ribs of the web of .the bar il. The 40 longer rail. To meet this diñiculty, the inven 40 tion includes the provision of a false rail and fish plates 6 embrace by their outer ends the rail ends l, 2 and are so connected therewith between the rail end proper and the wedge shaped member, which false rail end is rigidly by bolts 'l that the rails'on- either side of the joint can expand and contract under the ac 4 connected to the rail endproper and carries the tion of heat. 45 wedging surface, the rail end proper being cut The top of the web of the bar 4 is cut trans perpendicularly to the longitudinal axis of the versely in dove-tailed formas sho-wn in Figure rail and the angle of the wedging surfaces on the 3 and forms a guide for a wedge-shaped member false rail end and the adjacent end of the wedge 5 shaped member being of a magnitude to suit 8 which is provided on its narrower edge with a downwardly directed arm 9. Two bolts I0, which 50 the length of rail on that side of the joint. are drawn through the two fish plates 6 and The invention will now be further described with reference to the accompanying drawings through the web» of the bar 4, pass through this arm 9. On these bolts are arranged springs Il which illustrate two preferred embodiments by which bear by one of their ends on the outer 55 Way of example. fish plates 6 and with the other end on the inner 55 2 2,085,885 surface of the vertical arm 9 of the wedge shaped member 8.

A rail joint connection as speciñed in claim The difference between the two embodiments con sists in this, that the rails are not cut off obliquely but at right angles to their longitudinal axis. The cut preferably follows in a zigzag line (in 15 elevation) in such manner that the rail end 20 Y 2.

A rail joint connection of the class herein ' ~ The second embodiment of the inventionris particularly adapted for those parts of the track where the rails on either sicle of the joint are of unequal length. It isV to be understood, how ever, that it is not limited to this case. , As previously indicated herein, in the case re 40 ferred to where the> rails on either side of the joint are of >unequal length and in consequence the heat expansions and contractions on the two sides of the joint are unequal, it is necessary to suit the angle of the wedging surfaces at the two ends respectively of the wedge-shaped member to the respective lengthsof the rails. Thus, the wedging surface adjacent the shorter rail would have an angle somewhatY greater than that adja cent the longer rail, so as to enablethe wedging surfaces onthe Wedge-shaped member correctly to rest on the corresponding wedging surfaces of the false rail ends. The wedge form, therefore, of the false rail ends should be suited, as stated, to the lengths of the rails to which they are respectively connected. described »comprising obliquely cut rail ends, a wedge shaped member, a support for said wedge shaped member inserted between the rail ends, means securing said wedge-shaped member resil iently to said sup-port, a dove-tailed transverse groove cut in the top of said support with its 404 walls lying in planes perpendicular to the vertical longitudinal plane of the rails, a correspondingly dove-tailed transverse guide element on the lower surface of the Wedge member and forming part thereof, a sleeper plate being common to both said support, at at least one end thereof, and the adjacent rail end, means to aiiìx said support to said> sleeper plate, and ñsh plates to connect said support to said raillends. ` ' 6.
