It is customary in laying rails, to provide a space between the oppositely disposedend faces of the lengths of the rails inline, sufficient to permit of the free longitudinal expans ion of the respective connected lengths of'the rails due to increase of temperature, and thus to avoid deformation of the rails consequent derailment of the rolling sa k.

In practice, the spaces thus left between the ends o f the lengths of the rails permit of the fiexureof the ends of the rails'in' the passage over them of rolling stock, reason of the weight of the latter, whereby as the wheels leave the end ofone rail, the

adjacent end of the other rail in line is d sposed' at a slightly higher le'vel, whereby undesirableshocksare imparted to the rolling .stOckQwhich result in inconvenience to passengers and disadvantages the maintename of the rolling stock and the permanent way. I

t' is one of the objects of the invention to avoid these disadvantages by means that are equally applicable to railway rails and tramway rails. 1

A d n to the nv a eny an nterm diate member is applied between adjacent lengths of rail in line, and serves to connect them, and this intermediate member is provided with a part of a shape corresponding to the head of the rails to extend over the space between the ends of the rails in line, so that thus, on a wheel passing from the end of one rail, itbecomes supported on the in-. termediate member, and on leaving the intermediate member, it then passes to and is supported by the adjacent rail.

The said intermediate member is'mounted and connected in such manner that the flexure of the adjacent rail ends cannot take place independently, and thus the adjacent rail ends under load are not momentarily disposed at different levels, and thus resulting shocks are avoided. Moreover, the move ment of the wheels from rail to rail and over the jointing member, is smooth and does not cause vibration.

r The invention is illustrated by way of example, in the accompanying drawing applied to a connection between two adjacent lengths of a railway rail in line.

Figure 1 is a perspective View of the intermediate member ready to be mounted between two lengths of rails in line,.provided as illustrated in perspective view in Figure 2.

Figure 5 is a plan view showing the cornplet e d connection of the ends of two adjacent rails in line and showing the intermediate member disposed upon and between the opposite ends of the" lengths of rail, while Figure 4 is a side View opposite to that-at which the intermediate member is applied.

As illustrated in the accompanying drawing, the rails land 2 disposed in line, have their heads partially removed to forinrecessed parts 13 and 4 by which two inclined faces are thus formed extending from the inner side of the rail heads downwardly to the outer side, andby which also adjacent end faces are formed which are inclined out wa rdly fromthe innervside" of the rail heads 7 to the outerside thereof, whereby the angle indieated at 5 in Figure 3 between theinclined end faces is obtuse, 1' I -The' intermediate -meinber, Figure 1, is provided with a part 7 which is complementary to the recesses formed in the heads of i the adj acentlengths of rail that is to 'saythe intermediate member is providedwithan -inclined bottom face which is adapted te'lie upon the inclinedfaces ofthe recessed parts 3 and 4 and with inclinedend faces that are adapted to lie in contact with the end faces of'the said recessed parts, so thatwhen the intermediate members is applied in position, it completely fills the recesses, and its upper surface 8 forms a continuation to the upper part of the normal section of the head of the connected rails, so that thus, on the intermediate member being set into position, the part 7 forms, with the adjacent rail heads of normal section at 9 and 10, a substantially continuous rail head and surface upon which the wheels of the rolling stock mayv roll, and in which, instead of, the usual butt jointing space 6 being exposed on the top of the rail head, a joint 11, 12, 13 and 14 is formed that extends from one side of the "rail to the other, in the manner indicated in Figure 3.

The intermediate member, Figure 1, in addition to the part 7 integrally formed with it, is provided with a lower mounting plate 15 having holes'16, 17, 18, 19 therein,

' by which it is adapted to be fixed by means of bolts 20, 21, 22, 23 to the web of the rail" in position beneath the normal head thereof. This mounting plate, at its lower edge, is applied against the feet 34, 35 of the respective adjacent rail lengths, in such manner; that the ends of'the lengths are not free in their movements of fiexture. If it be supposed that the rolling stock passes from left to right by reference to Figure 3, the wheel which is supported upon the whole width 24 of the rail head, by reason of the acute angle 25 and its opposite angle 26, gradually loses the support of the rail 1 and gradually acquires support upon the part 7 of the intermediate member until the line 27 is attained, whence it gradually loses support from the part 7 of the intermediate member and radually acquires support upon the rail 2 y reason of theacute angle formed at 28 and the opposite acute angle formed at 29 i between the adjacent parts of the head section 7 of the intermediate part and the normal sectionof the head of the rail.

It will be understood that the superficial profile of the upper part of the intermediate member may correspond to the normal profile of the head of the adjacent rail sections in order to avoid irregularities, and in order to ensure smooth running over the joint between the ends of the rail lengths. It will thus be understood that the passage of rolling stock over the rail joints is imperceptible and without shock or vibration, since the usual transverse joint is replaced by a joint havin a broken confi uration which a proaches the longitudinal axis of the rail,

and which does not permit of the independentflexure of the connected rail ends:

The intermediate member as hereinbefore described, is.mounted by means of bolts 20, 21, 22, 23 in applying on the opposite side ofthe rail, an ordinary fish plate 36 corresponding to the plate 15 and adapted, as is I the plate 15, to engage on the feet of the respective rails and the rail heads, and the rails are provided with corresponding holes or slots 80, 31, 32, 33 for the passage of these bolts.

I claim 2- A joint for rails comprising in combina-' inner side of the rail head to the outer side thereof and to form a corresponding end face to extend transversely and outwardly .from the inner side of the respective rail head to the outer side thereof, and an in termediate joining member having a head part whose profile corresponds to that of the head of the said rail lengths and of a form adapted to fit within the cavity constituted of the oppositely disposed recessed parts formed in the heads of the rail ends, the said head part of the joining member having inclined ends and an inclined under face and the said oining member being adapted to be secured to the adjacent ends of the rail lengths whereby the rail head part of the saidjoining member is maintained in position within the said cavity and in contact with the inclined faces thereof, substantially as hereinbefore described.
