RAILROAD-TRACK CONSTRUCTION.

Application filed May 22, 191

To all whom it may concern:

Be it known that I, VVILLIAM H. MORGAN, resident of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Railroad- Track Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in railroad track construction, the object being to provide means for so supporting the rails that the load will be distributed over a series of ties, thereby permitting the use of smaller rails than can be safely used on a track in which the rails are supported at intervals on the ties.

With this object in view my invention consists in the parts and combination of parts as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of a section of a track embodying my invention; Fig. 2 is a view in vertical section through a rail and its. supporting girder and showing the supporting means for the latter; Fig. 3 is a view similar to Fig. 2, showing the rail insulated from the tie; Fig. 4- is an end view and Fig. 5 a side view of the construction shown in Fig. 2 applied to a wood tie; Fig. 6 is a view of a section of a tie showing the rail supporting chair and rail locking clips; Figs. 7 and 8 are views of the rail locking clip and Figs. 9 and 10 are views oi modifications.

1 represents the tie, preferably made of steel, I-shape in cross section, and provided with a base flange 2 wider than the top flange 3, the said base flange being preterably inclined downwardly as. shown in Fig. 1 so as to form a housing under, or within which, the ballast will pack when tamped. Secured to the top flange of the tie, are the chairs, each of which is composed of two sections 4 as shown in Fig. 6. These chairs are preferably made of sheet steel pressed or stamped into shape, and each comprises an upright member 5 terminating at its top in a shoulder 6, and upwardly projecting flange 7, the free upper edge of which latter is turned inwardly toward the rail, and a base member 8, all of said parts being in tegral. Each chair section is strengthened and reinforced by the rib or brace 9, which Specification of Letters Patent.

latter is stamped or pressed out from the upright base member and shoulder, and er;- tends from adjacent the outer edge of the base member to approximately the outer edge of the shoulder, and operates to pre vent any outward deliection or collapsing of the chairs under any stress to which they may be subjected. The base member of each section of the chair is provided at its side edges with the flanges 10 which are bent around under the top flanges 8 of the tie, and lock the parts or sections 01 the chair in place. If desired the two sections of a chair may rest on a plate 11, as shown in 4L and 5. This plate has upturned flanged ends 12, which engage the outer edges of the base member of the chair sections and operate to prevent the possibility of any separation of the sections. When used on a metal tie, the parts including the plate will be locked to the tie by the flanges 10 of the chair section engaging the top flange of the tie, and when secured to a wood tie, as in Figs. 4 and 5, they will be secured by spikes or screws l2 passing through the base plates and plate 11 and into the tie.

The girders or stringers 13 are preferably old steel rails, placed head down be tween the upright members 5 of the chair, with their base flanges resting on the look ing clips 14 seated. on the shoulders 8 of the chair. Any other form of girder, will however answer the purpose, but I prefer old rails, on account not only of their cheapness, but also because of the superior metal of which they are made. T he girders or stringers 13 are suspended between the sections of the chairs, clear of the ties and support the rails throughout the length of the latter, except possibly at switches, and are arranged to break joints with the rails, so that a joint in the rails, and a joint in the girders will not come between the same ties. The ends of the girders are connected by fish plates 15 and the ends of the rails are also connected by fish plates, and they are both secured to the chairs by the locking clips 14-. The clips are approximately as long as the tops of the chairs, and each is approximately U-shape, the lower member being longer than the upper member. and provided centrally with a tongue 15 integral therewith, the portion of the lower member of the clip which forms in effect a continuation of the tongue, being depressed below said lower member so as to form a projection, which, entering the recess in the shoulder 6 formed by stamping or pressing out the rib or brace 9, operates to lock the clip in place against endwise movement. The free ends of the tongues 15, extend downward between the two members of the chair and bear with a spring pressure against the opposite sides of the web of the girders 18, which operates to not only hold the tongue 15 within the recess formed by stamping up rib or brace 9 from shoulder 6, and lock the clip against endwise displacement, but it also holds the clip solidly against the top flange of the girder with the upper member or lip of the clip over the base flange of the rail. The upper free ends of the flanges 7 of the chair sections, are curved inwardly to slightly overhang the clip, so that when the clips are in place they are positively held against vertical. displacement. The upper members of the clips overhang the base flanges of the rails without contacting with the same, thus leaving the rails and girders loosely seated on the lower members of the clips, and free to move lengthwise without opposition, and also free to move vertically a limited distance. The only pressure to which a rail is subjected other than downward, is an outward one,

' which is taken care of by the side flanges 7 of the chair, hence there is theoretically, no tendency of the rails to tip, but as the ends of the clips overhang the base flanges of the rails, and are only removed therefrom a limited distance, tipping to anything like a dangerous extent will be absolutely prevented by the overhanging members of the clips.

The clips are struck up from sheet steel, and are inserted endwise, or in the direction of the length of the rails, and preferably after the girders and rails have been placed on the chairs, and each is provided on its inner face in the plane of the base flange of the rail, with a series of projections 17, the projections on one clip being greater than those on its companion clip, so that by removing and reversing their positions the rail can be adjusted or moved toward the other rail of the track to compensate for wear. In the construction shown in Fig. 2, the larger projections 17 are at the left, or at the inner side of the rail. If now the inner face of the head of the rail should wear sufiiciently to affect the gage of the track or necessitate re-adjustment of the rails, it can be readily and quickly done'by removing the clips and placing those with the longer projections at the outer side of the rail, thus shifting the rail a distance approximately equal to the difference in the length of the projections. It will be readily seen that this same result can be accomplished by providing one clip only of each pair with projections.

With the construction above described, the load is distributed equally on and between a series of ties, and does not fall wholly on the ties in the vertical plane of the load, and by using old rails, instead of built up girders, all objections to riveted structure is avoided. By supporting the rails on suspended girders, a lighter rail can do the work of a much heavier rail that is supported only at intervals, so that with my improvement much smaller rails can be safely used with the heavy rolling stock that is now rapidly coming into use, and which could not possibly be used if they were supported only at intervals. By the use of girders or stringers in conjunction with cross ties, I distribute the rolling load uniformly over the cross ties; considerably reduce the pressure per square foot between the ties and ballast and also reduce the cost of maintaining the road bed owing to the fact that less retamping will be required. Again the construction is absolutely clear of external projections which could be engaged and knocked off by the wheels in the event of a derailment, and by changing the shape of the cross sectional area of the clips, rails of all sizes and weights may be used without disturbing the chair, ties or ballast. \Vhen it is necessary to insulate the rails from the ties, it may be done as shown in Fig. 3 by inserting insulating material 18 between the clip, and the shoulder and flange supporting the latter, or the insulating material may be inserted between the tie and chair sections as shown in Fig. 9. Again the improvement may be used with metal ties of the hollow variety, by simply passing the side flanges 10 of the chair sections through slots in the top of the tie and then bending the flanges up against the under face of the top as shown in Fig. 10.

It is'evident that many slight changes might be resorted to in the relative arrange ment of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to restrict myself to the exact construction and arrangement of parts shown and described but,

Having fully described my invention what I claim as new and desire to secure by LettersPatent, is
