T 0 all whom "it may concem': 1

Be it known that I, Janus R. JOHNSON, a

citizen of the United States, residing atv Milltown. in the county of Berrien and State of Georgia. have invented a new and useful Railroad-Joint, of which the following is a specification.

This invention relates to rail joints and its object is to provide improved means whereby two .rails can be securely held together. without the necessity of utilizing bolts such as commonly employed.

Another object is to provide a novel form of fish plate having improved means for holding it in place, said means being formed integral with the rail and cooperating with removable means engaging the base flanges of the rails, all of said means being such as to permit the necessary expansion and contraction of the metal.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts herematter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, Figure 1 is a side elevation of a rail joint embodying the present improvement. Fig. 2 is a section on line .'\B of Fig. 1. Fig.- 3 is a perspective view of one end portion of a rail embodying the present improvement. Fig. 4 is a perspective view of a portion of a fish plate. Fig. 5 is a vertical section on the line CD of Fig. 1. Fig. 6 is a perspective view of one of the locking blocks. I

Referring to the figures by characters of reference, 1 designates the rails to be held together, each of these rails being provided at each end with lon itudinally extending ribs 2 formed upon the lower face of the head 3 of the rail, said ribs being spaced from the webs 4 and having lugs 5 interposed between the web and the ribs, said lugs being preferably disposed in pairs as shownparticularly in Figs. 1 and 3. A slot 6 is formed in each base flan e of the rail and adjacent each end thereo this slot beingdesigned to receive a block 7 having an upstanding tapered lug 8 thereon. A notch 9 is formed in each base flange for the purpose hereinafter stated. The fish plates 10 used in connection with the rails have notches or recesses 11 in their upper edges, each edge being of such thickness as to be I readily inserted between the web 4 and one of the ribs 2, the notches being arranged to receive the lugs 5 when the fish plate is inserted back of the rib. The base 12' of the fish plate is designed to rest on the base flange of the rail, and has a slot 13 therein into which the lug 8 projects, the length of the slot being slightly greater than that of the lug so as to permit the necessary expansion and contraction of the metal. A notch 14 is formed within the edge of the base 12 and is designed to register with the notch 9 so as to receive a spike 15 utilized for securing the rail. and the fish plate in position.

The notches or recesses 11 are preferably slightly longer than the lugs 5 'so as to permit a slight play and not interfere with the expansion and contraction of the rails.

In assembling the parts herein described i the rails are placed with their ends together and the fish plates 10 are then inserted be tween the ribs 2 and the web 4 so as to cause the lugs 5 to project into the notches or recesses 11. The bases of the fish plates are then moved on to the base flanges ,of the rails and by lifting the rails the locking blocks 7 can be inserted into the slots 6 from beneath the rails. Lugs 8 will thus be forced upward into the slots 13 registering with the slots 6 and afterthe rails have been lowered it becomes impossible to remove the blocks 7 therefrom. As long as the lugs 8 project into the slots 13 the fish plates are properly held and cannot be detached, the only way in which this detachment can be effected being by lifting the rails a sufiicient distance to permit the blocks 7 to be forced downward and out of the openings 6. After the various parts have been assembled in the manner described the rails are secured to the ties in the usual manner, certain of the spikes being driven through the notches 14 and 9,80 as to securely hold the rails to the ties at the points where the fish plates are located.

It will be seen that a joint such as herein described serves to securely hold, the rails together without the necessity of utilizing bolts or similar fastening devices and there are no parts which can work loose and thus permit accidental disconnection of the rails.

Various changes can of course be made m the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the inventio tion of the lugs,

What is claimed is 1. In a rail joint, the combination with abutting rails having depending longitudinally extending ribs upon the head thereo1 and spaced from the web and lugs interosed between the ribsand the web, of sh late insertible between the ribs and the web and having notches for the recepthere being registering apertures between the base flanges of the rails and the bases of the fish plates, and means held from vertical movement within the said apertures by the bases of the fish lates for holding'said bases upon the base anges.

2. In a rail joint, the combination with abutting rails having depending longitudinally ext-ending ribs upon the heads thereof and spaced from the webs, and lugs inter-- and webs, of fish plates disposed between the ribs and web posed between the ribs and having recesses for the reception of the lugs, there being registering apertures within the base flanges of the rail'and the bases of the fish plates, and a locking-block mounted within each aperture in the basefianges and each lapped and retained by the base of a fish plate, said blocks having projecting portions extending into the apertures in'the bases of the fish plates.

3. A rail joint consisting of abutting railshaving longitudinally extending ribs upon the head thereof and spaced from the rail webs, there being lugs interposed between the ribs and webs and an aperture within each base flange of each rail and a fish plate fish plate,

vture 1n the presence of two insertible between each rib and the Webs of the'rails,

said fish plate having recesses for the reception of the lugs, said-fish plate having apertures in the base thereof 'registering with the adjoining apertures in the base flanges and a locking block reinovably mounted within each base flange and lapped and held by the base of a fish plate, each block having an integral projection extending into the adjoining aperture in the fish plate.

4.'A rail joint including abutting rails having lon 'tudinally extending ribs upon the lower aces of the heads thereof and spaced from the webs, there being lugs inter osed between the ribs and webs, each rail aving an aperture in each base flange there of, fish plates insertible between the ribs and Webs and having recesses for the reception of the lugs, there being apertures in the base portions of the fish plates and registering with the correspondi apertures in thebase flanges, a locking bloc removably mounted within each aperture in the rails and lapped and held in the aperture by the base of a each block having a projection extending'into the adjoining aperture in the base of a fish plate; r In testimony that I claim the foregoing as my own, I have hereto afiixed my signawitnesses.
