METAL RAILWAY B LIKE SLEEPER, AND BAIL ATTACHIHENT THERETO.

Application filed November 2, 1922. Serial No. 598,681.

To azz whom it may concern.

Be it known that I, Louis MICK, a subject of the King of the Belgians, residing at Tilleur-lez-Liege, Belgium, have invented cer tain new and useful Improvements in Metal Railway or like Sleepers and Rail Attach-- ments Thereto, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to railroad ties and has for its object to provide an improved railroad tie of metal and simplified devices for attaching the rail thereto, characterized by the complete absence of the necessity for any holes or perforations in the metal tie or in the supporting plate or chair, andalso by the absence of bolts, spikes or thelike, for effecting the connection of the rail to the sleeper. The invention has also for object to construct the supporting plate or chair in two parts, in order to permit an assembly which is rapid, economical and possessed of the required conditions of solidity and security.

The invention consists in the construction and combination of parts, as hereafter described, by Way of example, with reference to the accompanying drawings in which Figure 1 represents a section of the rail, the tie and the devices for fastening the rail upon the tie, the section being taken on line AB, Figure 3.

Figure 2 is a cross section of the tie on line C-D, Figure 1.

Figure 3 shows a part view in plan of the rail and tie, as well as the fastening devices.

Figure at is a part sectional elevation lengthwise of the tie, on line EF, Figure 5, showing only a single rail fixed to the tie.

Figure '5 is a part view in plan of the extremities of the tie upon which only a single rail is fixed. I

Referring to these figures, the metal tie 1 of inverted U or like section includes two or more longitudinal walls or ribs 7 formed upon its upper face and spaced one from the other in such a way as to form between them a space or gap 9 of suitable width, as will be hereafter described. The middle portion of the tie is provided with a longitudinal groove or trough 8 extending approximately the full length of the tie.

These walls or ribs 7 are discontinuous at the rail seats, ending at these points in undercut faces 11.

The supporting chair plates comprise on the one hand wings orlugs 12 and 13 partly covering the edges of the upper face of the base or flat bottom of the rail and on the other hand projections 6 forming at their middle portions tenons which fit in the space 9 of the tie l and engage at their ex tremital edges 10 which are of dovetail section, under the extremities or beaks 11 of the walls or ribs 7, correspondingly undercut or profiled as above set forth.

Lastly a retaining device such as a key 4 of suitable cross section, preferably tapering, is engaged in the space formed between the edge of the rail base and the corresponding similarly tapered face of the gap formed by the wing'or lug 12 of the supporting chair 2,

overhanging the base of the rail 5.

Between the supporting chair-plates 2 and 3 there is left a space 15.

From the foregoing description it will be understood that the assembly is effected as follows. Upon the tie 1 there is placed at the assembly point a chair-plate 2 of which the tenon 6 is engaged in the space 9, and the edges 10 under the correspondingly profiled faces 11 of the walls or ribs 7, this engagement being produced by a movement imparted to the plate 2 in the longitudinal direction of the tie. The chair-plate 3 can be placed in position in like manner, because when'the assembly is effected, see Figure 1, a clearance space 15 exists between the internal edges of the plates 2 and 3. The rail can then be introduced perpendicularly to the tie, the edges of the base engaging under the parts 12 and 13 of the chair-plates 2 and 3, and the key or retainer 4: afterwards in-' sert'ed in place. After this key has been introduced and suitably driven into position, as shown in Figure 4, the end 14: of the key 4: is slightly bent up as shown in Figure 3, to prevent it being dislodged. It will be observed from Figure 1 that the overhanging lug 12 of the chair plate 2 is high enough with respect to the lug 13 of plate 3 to permit the rail to be placed in the chair plates Without the necessity of canting said rail.

, hand edge, looking'at Fig. 1, of its base flange clears lug 13; the railmay then be lowered until it rests upon the plates 2 and 3 and finally moved horizontally to the right into the position shown in this view. Another way of placing the rail in the chair plates without canting the rail is to place both plates 2 and 3 in inclined position so that the space between the lugs 12 and 13 is wider than-the base flange of the rail, whereupon the rail may be lowered between the lugs and then the whole lowered to horizontal position, the lugs closing in over the edg'es'of the-base flange. V a

As wear or slack takes place at the key, it is taken up by again driving in the key and correspondingly bending up the part 14.

This last operation can. be easily effected by alever or any other suitable instrument.

It follows from the above description that the tie with its connection tow the rail, forms a rigid whole, advantageously resisting transverse, longitudinal and upward strains on the rail. By reason of the \vedging of the rail in the lugs 12 and 1301": the chairplates 2 and 3, these latter tend to separate and this causes a tightening of the faces 10 and 11 preventing transverse movements of the rail; relative longitudinal movements between the railandv the chair-plates 2 and 3 are prevented by the tenons 6, engaged in the ap 9 in the tie. V

Tie lifting of the rail resulting from an upward pull is prevented by the, lugs 12 and 13 of the plates 2. and 3, which being engaged under the faces of the dovetail ends 1 11 of the ribs 7, can yield only if a closing together of the plates 2 and 3 be possible; this, however, cannot take place, the width of the base of the rail and the thickness of the key or retainer 4 preventingthose parts 2 and 3' from closing together. 7

The advantages of the improved arrange- .ment are easily seen from the foregoing.

It Will be clear that no holes or perforations of any kind are required in any one of the parts, and that there are no bolts, spikes or otherdevices as hitherto employed, while the rapidity .and security of. the assembly will be .obvious.

Having thus described' my invention what I claim is:-' r 7 a V 1. In a railroad tie, the combination of spaced ribs extending longitudinally of the u per surface of the tie, adapted to rest upon the. upper surface of the tie, tenons upon said chair-plates, said chair-plates tenons fitting between said ribs, interengaging surfaces upon said ribs. and chairplates maintained in engagement by separation of said chair-plates, and means for securing the rails to said chair-plates, said securing means tending toseparatesaid chair-plates. V

2. In a railroad tie, the combination of spaced ribs extending longitudinally ofthe upper surface of'the tie said ribs being discontinuous at the rail seats, chair-plates adapted to rest upon the upper surface of the tie at the rail seats','tenonsupon said chair-plates, said tenons fitting between said ribs, inclined surfaces upon said chairplates, correspondingly undercut surfaces on said ribs at their. ends adjacent the rail seats and means for securing the rails to;

said chair-plates, saidsecuring means tendmg to separate said chair-plates and to maintain said inclined surfaces in engage,

ment with said undercut surfaces.

3. In a railroad tie, the combination, of spaced ribs extending longitudinally ofthe upper surface of the tie, said ribs being discontinuous at each of the points of attachment for the rails, chair-plates adapted to rest upon the upper surface of the tie at each of said points. of attachment, a tenon upon each of said chair-plates,v adapted to fit between'said ribs, interengaging surfaces upon each chair-plate and the adjacent ends of said ribs, and means for securing a rail to-the chair-plates located at each assembly,

point, said securing means including hooked fiangesoverhanging the edges of the rail base'and a, retaining device adapted to be driven between one'of said flanges and the corresponding edge of the rail, said interengaging surfaces being. maintained in engagement by the separation of the chaira tenon upon-each: ofsaid separable sections,

said tenons fitting between said ribs, and means for securing the rails to saidfchairs,

said securing means serving to separate thesections of said chairs. h
