Specification of Letters Patent.

Application filed November 27, 1907.

Serial No. 404,071.

To all whom it may concern:

Be it known that 1, JOHN WV. CALDER, a citizen of the Jnited States, residing at Parnassus, in the county of lVestmoreland and State of Pennsylvania, have invented or discovered new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to railway ties composed preferably of metallic structural shapes, such as Z-bars, and channels keyed together in pairs and preferably provided with rail fastenings of the type shown in. Patent, No. 82 8,3416, granted tome March 26, 1907.

Referring to the accompanying drawings, Figure 1 is a perspective of one of my improved tics, wherein I employ Z-bars; Fig. 2, a section of Fig. 1 on the line 22; Fig. 3, a cross-section of Fig. 2 on the line 83; Fig. 4, a perspective of the preferred form of a protector which may be used with my improved tie; Fig. 5, a perspective of a tie made of two channels with their flanges contiguous; Fig. 6, a perspective of a tie composed of a pair of channels placed back to back; Fig. 7, a cross-section of Fig. 5, the rail and fastening being shown Fig. 8, a cross-section of Fig. 6, the rail and fastenings being shown; Fig. 9, a perspective of the preferred form of key for locking the sections of my ties together; Fig. 10, a perspective of one form of rail fastener; and Fig. 11, a perspective of a liner which I prefer to use to take up wear or looseness.

Referring to Figs. 1 to 4:, 9, and 10, 1 represents apair of Z-bars having their lower flanges 2 horizontal and extending away from each other and their upper flanges 3 horizontal and extending toward each other and preferably contiguous. The bars 1 are provided with L-shaped slots 4;, arranged in pairs, one member of each pair being opposite the corresponding member in the respective bars. The L-shaped slots have a horizontal portion from which the vertical portion extends downwardly. I have shown the tie in Fig. 1 with two upper L-slots and three lower L-slots. The upper slots being preferably close to the flanges 3, and the lower slots are preferably close to the flanges 2, so as to brace and tie the bars 1 firmly together.

Keys 5 (Fig. 9) are inserted in the horizontal members of the pairs of L-slots 4. with the notches or slots 6 facing the vertical members of the slots 4:. These slots 6, of

which there are two in each key, are spaced apart to correspond with the distance between the vertical members of the Z-bars 1 and the width of the slots 6 equals the thickness of the said Z-bars. It is clear, then, that, when the keys 5 have been inserted in the slots 4 as described with the slots 6 opposite the said vertical members of the bars 1 the keys may be slid toward the vertical members of the L-slots 4L and then rotated a quarter revolution, so that the reduced portions of the keys will stand in the vertical members of the slots 4; with the tops of the notches 6 resting on the lower ends of the slots 4L. Thus placed, the keys cannot rotate back to a horizontal position and disconnect the bars 1 and they will prevent the said bars from independent lateral and longitudinal movements. The bars 1 may be readily taken apart by removing the keys 5 in an obvious manner.

The rails 7 are secured to the ties by means of the fasteners 8 which are similar to those shown in my said patent. The fasteners have depending lugs 9 which extend through slots 10 in the top of the tie and at opposite sides of the rails. The part of the fasteners 8 above the ties is wider than the slots 10 and rests on the upper face of the flanges 3, as shown on Figs. 1 and 3. The fasteners have projecting fingers or lugs 11 which pass over the rail flanges and preferably touch the web of the rail, as shown on Fig. 2. The edges of the rail flanges rest preferably against the shoulders 12 on the fasteners. The lugs 9 have the transverse slots 13, through which the keys or pins 141 pass, the ends of the keys or pins lying in the slots 15 in the bars 1, these slots being located with their upper walls substantially in the plane of the lower faces of the flanges 8, so that the keys will have a long support against the said flanges and thereby prevent the bending or breaking of the keys. The keys 14 may be held in place, as shown in my said patent, by the cotter pins 16.

Ballast is placed inside the ties, but preferably not in that portion provided with the fasteners 8. To keep the ballast out of this portion of the ties, I provide the protector shown on Fig. 4. This protector has the body 17 provided with the inturned flanges 18 spaced apart and proportioned to be slid over the flanges 2 of the ties. The central portion of the body 17 has at each end an upturned flange 19 and the lateral portions of the said body have at eachendth down-1 wardly bent flanges 20. Thebody 17 is sufliciently long to have the flanges 1 9.in elude between them the lugs 9 of a pair of fasteners S. The flanges l9 keep the ballast away from the keys 14 and the fasteners and the flanges 20 aid in preventing endwise movement of the protector and the tie, the protector being secured to the tie by means of the pinsfl2luin the holes 22 in the protector and the flanges 2. V

In Figs. 5 and 7, the construction is the same as in Fig. 1, except that the flanges 2 of Fig. 1 extend into contact with each other, the slots 10, being as shown in Fig. 1, out half in each, member of the tie.

In Figs. 6 and 8, the channels ;3, instead of having theirflanges facing each other as in Figs. 5 and 7, have their backs or vertical members arranged opposite or facing each other. Their backs are spaced apart suffi- 'ciently to receive between them the lugs 9 ofthe fasteners. The keys 5 and 14 are applied the same as in the two preceding forms of my invention. Slots 24 are cut in the upper, angles ofthe channels to receive the upper portionof the fasteners, as shown in Fig. 8, so that the fasteners may be held by the ends of the slots Qelfrom moving transversely ofthe rails. p I In case there is any looseness in the fit of the fasteners 8 in the slots 10 or 24, the liners 25 (Fig. 11) may be placed in the outer ends of the slots, as shown in Fig. 2. These liners are Z-shaped, the upper members resting on the tops of the ties, the middle or vertical members standing between the outer ends of the slot lOor 24c and the outer ends of the fasteners 8, and the lower member lying beneath the said fasteners. Thus, it will be seen that the liners will be firmly held in place as they cannot, owing to the said upper and lower members, fall or jump from their proper places. Liners of diflerent thicknesses are provided so that the exact amount of looseness may be taken up by the use of liners of the required thickness. I have extended the upper or wider portion of the fasteners well toward the outer ends thereof so as to prevent any torsional strain on the keys 14 and to give the fasteners a larger and longer base. The slots 10 are preferably in the edges of both the flanges 3.

.I do not restrict myself to the precise combinations and elements shown and described.

I claim 1. In a metallic railway tie, the combination of a pair of metallic angle bars, having therein opposite pairs of slots, keys extending through the pairs of slots and having therein notches to receive the walls of the said bars.
