of which the following is a specification.

This invention relates to rail-joints, or more particularly,v to railway-track joints and the object thereof i's to provide a boltless joint, the same consisting of a pair of corresponda slidably-connected plates partially ma e' to conform to the lower part i of the rail beneath the ball or head thereof `and adapted to rmly hold or contain between them two butt approaching or contacting ends of a pair of rails.

The details of my invention will be fully hereinafter described and the actual consistency thereof will be vduly referred to in the description of the construction and arrangement of the several parts and also particularly poi1- tedout in the claims.

In the sheet of drawings accompanying this description, Figure l is a perspective view of a rail-joint embodying my invention, one end of one of the rails being shown in section and the device appearing as in use; Fig. 2, a bottom plan view of Fig. l, but on a reduced scale and showing the two jointed rails broken olf at, either side thc joint; Fig; 3, a bottom plan view of one of the sections or members of the joint embodying4 my invention, taken on the-same scale as that seen in Fig. 2; Fig. 4, a view similar to Fig. 3, but of the companion section or member of the joint comprising my inven tion herein; Fig. 5, a longitudinal elevation showing the inner face of the section or member seen in Fig. 4, but on a larver scale; Fig. (i, an end elevation of one ot the sections or members seen in Fig. l; and Fig. 7, a view similar to Fig. 6, but of the other section or member of the joint. (Both Figs. 6 and 7 are end views of the two sections or members of the joint, taken at the fore end seen in Fig. 1.

In these views, indicates each one of a pair of ordinary railway-track rails being duly s aced, as customary, at their adjacent, a utting ends, as shown at 2.

3 indicates one of the sections or members of the joint-making device comprising my invention herein and 4 indicates a companion section or member of said device. These members are each composed of a base Specication of Letters Patent.

The upper edgeof the said limb rests under one sideg-of-ftlie head' or ball ofthe rail 'and the lowerportion of said limb is brought into. close contact with thev said flange of the base of the rail, the base of each section ormember of the jointlying in close Contact with the bottom of the properly support said rail.

The sections or members 3 and 4 arezeach provided with notches 3 and 4, respecary distances from the opposite ends of the mcn'ibers, for the engagement of the ordinary .spikes or other suitable devices for fas` teninfr the joint in place on 'the cross-ties.

pass into Iirm frictional lockiiig-engagement Due allowance is made in the construction of the two companion members 3 and 4 for the tight 4drawing toc'ither thereof in engagement over thee-:ribes of the rails to be jointed, so that there shall not be any undue movement of the rail ends in relation to eachother to become Ploose or to rattle in the joint or on the cross-ties.

It Will be' readily seen that a joint made of the companion members 3 and 4., such as herein shown and described.I needs no cross bolts, nuts or other like fittings that-'are adapted to become loose and displaced in the use thereof and that need constant care to prevent looseness in the joint and aecident occasioned ly the separation of the orvdinary form of fish-plates from the joint. The usual allowance'ot space between the rail ends is d uly provided for, in fact, there is no definite limit to the space allowed between the rail ends in the use ot my eompanion members 3 and 4, for the reason that. there are no bolts or holes in the web of the rails or in said members 3 and 4 to limitsuch allowance. The rails can thusl expand and cortraet without limit to suit varying tem peratures and, there being nqholes in the rail webs nor in said companion members 3 'and 4,V said rails and companion 'members are not weakened in any manner such as are the fish-plates and rails that are joined together with bolts in general use. In use the two companion member-s3 and 4 are compaetly h "el'd together over the abutting ends of the1 j rails to be joined, and the usual spikes driven into engagement with the notehesiu the edges ot said companion members prevent. any longitudinal or sidewise movement thereof, althoughIl the above named snug frictio'nal engagement or drive-tit and the engagement 'of the tongues and grooves of Said 'Companion members 53 and 4 are amply sufficient to prevent any movement, either side- Wise or longitudinal, even if any of such spikes should become loosened or withdrawn.

' An extra precaution against longitudinal movement of the companion members 3 and .V4 can be taken 1n theprovision of spikes lriven into the cross-ties at the opposite ends of the. bases of said companion members 3 and 4, but it 1s not likely that such precalition will be necessary except in unusual or extreme cases. Y

lt is obvious that my companion members used. This is an important pointin the use ot' in v invention herein' and renders it extremely u'ell adapted to emergencies.

"2. A rail-joint eomprising a pair ofcompanion members each havingr` a base portion and an angular upright limb por ion, each the full length thereof, adapted` to contiguously engage under andover the rail bases and against the rail Avebs, respectively, inwardlyj'irojeeting portions along part of sa id base portions, tongue or elevated: formations along said 'iiwardlyprojecting portions, grooves or guide-ways constructed parallel to said tongue-formations in said bases asa DALY.
