Figure 19 is a plan view of the joint.

Referring particularly to Figures 1 through 5, the adjacent ends of two rails are indicated at 1, these rails having bolt holes 2 formed therein in the usual fashion. I

A fish plate 3 is formed with upper and lower fishing edges 4 and 5, respectively, these edges being received between the rail head and the bottom flange thereof in the usual manner. Apertures 6 are formed in one I end of the fish plate 3 to cooperate with the corresponding apertures 2 of'one of the rails.

operate with the corresponding apertures 2 in a rail to receive suitable bolts 8. These bolts are of standard "construction and are used interchangeablyv in connection with any of the holes described herein.

In the intermediate section of the fish plate,

an upwardly extending boss 9 is formed, the upper surface 10 of which is adapted to lie in the plane of the top of the rail head and thus form a continuation thereof. The boss is also extended inwardly, and formed with a face 11 which lies in the central vertical plane of the rail. In mounting the above described plate 3, the boss 9 is properly spaced with respect to the adjacentv circular aperture 6 to receive the rail end snuglybetween the edge of the shoulder 12 and the adjacent aperture. The fish plate is thus rigidly secured to the corresponding rail end and expands and contracts therewith. The other end of the plate is formed in such manner that the edge of the boss'13 is spaced a distance from the adjacent elongated aperture 7 equal to the distance betweenthe shoulder 12 and the adjacent aperture 6.

The joint is completed by providing a co operating fish plate 14 which is fornied'similarly to plate 3 and which has its elongated apertures 15 lying opposite the circular apertures 6 ofthe plate 3, thefcircular apertures 16 of'plate l4 lying opposite the elongated apertures 7 ofplate 3. The boss 17 of plate 14 thus is rigidly secured to the rail end to which the fish plate 3 is slidablysccured and its shoulder 18 thus snugly abuts its cooperating rail end. I The other shoulder 19 moves with respect to'the right hand rail as viewed inzFi 'ure 5 when ex ansion or contraction b 7 relative movement of the adjacent rail ends will be provided for by space afforded betwgen'the' shoulders and the respective rail en s.

In the construction shown in Figures 6, 7, 8, 9, 10 and 11, a fish plate 20 is formed with apertures in the manner similar to that described in connection with the plates 3 and 14. An upper boss 21 is formed on each plate and is provided with an upper surface 22 which conforms to the profile of the rail head the boss being formed with a face 23 which lies in the vertical central plane of the rail, in the manner described in connection with the face 11. A reinforcing portion 24 is also formed onthe plate and provided with downwardly depending boss 25, within which a bolt hole 26 is formed. The inner face 27 of the boss 'lies in the plane of face 23, a longitudinal groove 28 thusbeing provided between the upper and lower bosses. The cooperating fish plate is similarly formed and provided with a longitudinal groove and when the joint is assembled, a key 29, indicated in dot and dash lines in Figure 8, is

inserted in thecooperating grooves to cause the fish plates to be rigidly Inounted' agaifnst relative movement in a vertical plane." It will thus be seen that, should one of the bosses 21 of the fish plates receive the entire--'g.ravi- I tational load of a Wheel,- the key 29' willcause fish plates due to the gravitational stresses which are exerted upon the sloping faces 32 of the rails and the lowerfishing edges .5 of the plates. Since the bolt holes 26 are elongated, this bolt does notprevent the relative movement of the fishplatesiand thus the ex pansion and contraction of therails.

In the construction shown in Figure 12, the

fish plates are formed with interengaging tonguesland grooves which, in the form shown herein, include a longitudinal rib 33 7 formed upon theupwa'rdly extending boss $34 of one of the plates which ribiis adapted to be received; within a longitudinal groove 35,

formed within the upwardly extending boss 36 of the cooperating plate. The plate carry- 7 ing the boss 36 is likewise formed with'a lon V 'gitudinal tongue-or rib 37 which is received within a cooperating groove 38inthe plate which carries the boss 34, In this construction, thekey 29 is dispensed with and the .interen'gaging portions formed directly on the cooperating plates. 7 V From the foregoing, it will be seen thatthe cooperating fish plates are effectively inter connected to insure thecomplete distribution of stressesbetween the-plates and thus prevent llljlillOUS strains. from being impressed upon onlyone plate. The plates are furthermore effectively prevented from being separated by means of the bolt and as a result,

- a rail'connection is provided, the strength" of which -i-s fully preserved, at the same time afiording adequate provlslon for the expansion'an'd contraction of the rails.-

Referring. to Figures 13 to 16 the fishplate 101 hasa central upwardly projecting portion 102 which fits between the headset the rails to be-joinedJ In the'illustrati'on the fishpla te alsohas a downward projection 103 which entends below the lowerfishingsurfaces 104 of thefishplatea, The upperv extension102is-ofsuch a widththat it will not completely fill the gap betweenlthe rail ends to be :joinedbutwill allow a suitablespace for expansion; This upper extension is made of two widths. The thicker part 105" maybe approximately'two thirdsof the transverse width of the rail head to be used therewith, whilst the narrowerpart 106, .isapproximatelyone-third of, the width of the .said

rail head. The: part of greater, width 105 has thewidth of the rail head;

a corresponding part 107 of similar width thereto directly below it, but-the two parts 105 and 107 are-separated by a gap 108. Di- I rectlybelowxtheportionf106 is another portion 109' of similar'width thereto, but between "106" and 109 there is a projection 110 which, is of approximately the same width 1 i as the parts 105 and 107 In effect then the central portions 102and 103 of the fishplate 7 constitute a portion having a width which is substantially one-third of the width of the rail head and which has" thereon threeprojections, 105,-107 and 11 0' which project. inwardly from this surface. NVhen this fish plate is used :with a cooperating similarly cforn'ied f fish plate, the projections and grooves formed thereon interengage to. perunit relative axial movement without permit, ting relative vertical movement; j

The fishplates atone endhave' circular.

holes 111 which are a close fit for the fishbolts. The holes 112 at the other endsof the fishplates are slotted holes to permit relative axial movement of the plates. The fishplate I is so formed that when bolted-to a rail end,l V. the surface 113 shall make contact withthe end ofthe rail to whiclithatparticular fish plate is rigidly connected, owingto the bolts which .pass through and are a close fit inthe holes 111. The expansion gap is betwee'n the surfacelle and the rail endadj 'acentithereto.

It wi'll'b'e noted that the bolts whichisecure this :second' 'rail end to thefishplate pass through slotted'holes in this fishplate and accordingly' permit the .fishplate to moverelatively to that rail end tovtake up expansion contraction due totemperature variations.

.' A feature which will be clear from inspection-of Figure 18 is that thefishbolt's1-123 V 105 are moufntedyin such mannerthat their nuts 124 engage the fixediendsof the fish plates,

thus eliminating movement of the fish plates below such nuts. Thezparts of the fish plates which move have the heads 125 ofthe fish I boltsin contact therewith. This feature will be foundadvantageous since there is no tendency for thenuts to back awayfrom the plates if there is no movement of the fishplate surface against which-the nuts engage. To prevent the bolts fromturning whilcthe nuts are being tightened the fish plates above and below the'slotted holes 112 are provided with fins or ribs 126 which prevent the heads 125 of the'bolts'from turning.

From an inspection ofFigui'e 19, it will be seen .thati the above described construction providesthree expansion gaps, each substantially one third. of the widthof the rail'head, These. gaps are shownfat. 127,, 128, and 129.-
