GUARD-RAIL STRUCTURE.

Specification of Letters Patent.

Patented J an. 25, 1910.

Application filed May 20, 1909. Serial No. 497,349.

To all whom "it may concern:

Be it known that I, GEORGE B. TAYLOR, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Guard-Rail Structures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a new guard rail and chair therefor adapted for use on railroads and especially under conditions wherein the guard rail acts not only as a safety device but also to receive the direct lateral thrust of the car wheels. Guard rails of this character are perhaps subject to the most severe usage on passenger railroads of large cities, such as subway roads and elevated roads, in which the curves are not only numerous but frequently very sharp.

The ordinary guard rail and chair, which approximately meet the requirements of ordinary long-distance steam railroads, fail utterly when applied to local transit roads, and the members of the guard structure, particularly the bolts by which the guard rail and main rail are tied together, are so frequently displaced and broken that their maintenance and replacement is a serious item of expense.

In my invention, one preferred form of which is shown in the drawings and hereinafter described, a guard rail structure is provided that is adapted to resist the strains and shocks incidental to its use under the most severe conditions and is also adapted to be adjusted from time to time to compensate for the wearing away of the head of the guard rail.

While the invention is more particularly designed for application to railroad. tracks having sharp curves and over which trains travel at frequent intervals, it is also adapted for general use, not only in curves, but also at frogs, crossings and switches.

In the drawings: Figure 1 is a plan view of the structure, partly broken away; Fig. 2 is a side view of the chair, showing the guard rail in section and the main rail in dotted lines; Fig. 3 is an end view of the structure; Fig. 4 is a longitudinal section through the chair; Fig. 5 is a detail perspective view of one of the clips.

a is the main rail and b the guard rail.

6 is the base plate of the chair.

cl, d, are webs spaced apart and extending upwardly from the base 0.

e, f are ribs connecting the webs cl, (Z.

9 is a jaw extending upwardly from the base 0 between the webs (Z, (Z.

The members 6, f, extend at an angle to the longitudinal extension of the guard rail and main rail and, together with the inwardly and upwardly projecting member of the jaw 9, form a pocket for the reception of the web of the guard rail and for a wedge h to hold the guard rail in place.

To hold the chair to the ties the following means are provided: The outer end of the base plate 0 is provided with a lip 2', between which and the outer flange of the main rail is inserted a clip is, which partly overhangs said flange and is of a peculiar construction to be hereinafter described. A screw-spike Z extends through the clip and through a slot in the base plate 0 into the tie m. At the inner end of the base-plate 0 a ridge 0 extends parallel to the guard rail and against which is abutted a clip it. Another screwspike Z extends through the clip a and through a slot in the base plate 0 into the tie m. A third clip 1" rests upon the base plate 0 adjacent to the inner flange of the main rail and partly overhangs said flange and is secured in position by a third screw spike Z extending through the clip 1" and through a slot in the base plate into the tie m.

The guard rail is preferably of a peculiar cross-section approximately like that shown in the drawings, its head having a flat lower face and an upper face sloping somewhat upwardly from its inner toward its outer portion so as to present a relatively thick outer portion to receive the thrust of the wheel flanges. The outer face of the guard rail head is somewhat inclined downwardly and outwardly toward the main rail and is also somewhat concaved from near its lower edge toward its upper edge. The web of the guard rail is substantially closer to the outer portion of the head than to the inner portion thereof. The inner face of the web extends vertically while its outer face is inclined downwardly and outwardly to correspond with the inclination of the inner face of the u wardly projecting member of the jaw g of the chair. The bottom of the guard rail web is preferably flat.

To apply the guard rail, a suitable number of chairs are first fastened in position 'bf' means of the clips, and screw-bolts hereinbefore mentioned. Then the guard rail is dropped into the chair pockets, the web of the guard rail being first inserted in the inner side of the pocket and then moved outwardly against the jaw g. The wedge 71 is then inserted between the guard rail web and the rib f of the chair and is driven in by a hammer until the guard-rail is firmly i I locked in its pocket. As shown, the wedge it has a flange 71 that extends into a recess formed in the rib. f, thereby preventing upward displacement of the wedge.

In the course oftime the outer face of the guard rail will be worn away by the car wheels and it will be desirable to move the same toward the main rail to compensate for the wear. The peculiar construction of the clips and n permits the whole chair to be adjusted toward the main rail without the necessity of new bolt holes in the ties. The specific construction of these clips will now be described.

The clip la may be described as a square shaped member having a central bolt-receiving orifice and provided with four lateral flanges, two of which, 70 and 70 extend outwardly from two adjacent sides of the clip in line with one face of the clip, while the other two of which, k and 70*, extend outwardly from the other two adjacent sides of the clip in line with the opposite face of the clip. These flanges are of four different widths. For example, they may vary in width from three-eighths to three-fourths of an inch. The clip is may also be described as a clip having its bolt-receiving hole eccentrically located with respect to its extreme dimensions and cut-away along its four edges to form flanges of varying width arranged as described.

When a new guard rail is to be applied, the clip is inserted so that the narrowest flange is abuts against the lip z of the base plate 0. In the particular arrangement of flanges shown, the widest flange 70* will then overhang the main rail flange. This adjusts the chair at its farthest distance from the main rail.

The inner clip a is simply a square plate having an eccentrically-located bolt-receiving hole. That is, the distance from the center of the hole to the four sides of the clip varies to correspond with the variations in the widths of the flanges of the clip 70. Assuming that the chair has been set at its farthest distance from the main rail as before described, the clip a is so placed that the side thereof mearest its bolt-receiving hole abuts against the ridge 0.

The central clip 1" need not be adjustable and comprises merely a plate having a flange adapted to overhang the inner flange of the main rail.

After the head of the guard-rail is worn away and it is desired to adjust it toward the main rail, the screw-spikes Z are first loosened and the chair slid toward the main rail a distance (say) of one-eighth of'an inch or more. Then the clip is is lifted and given a quarter turn so that its flange k abuts against the lip z of the base-plate 0 and its flange 73 overhangs the main rail flange. Then the chair is pushed or driven so that the lip z abuts tightly against the clip is. The clip a is then lifted and given a quarter turn. The bolts are then tightened. It will be understood that notwithstanding this adjustment of the clips, the position of the bolt holes in the clips relatively to the tie remains unchanged, so that the bolts need not be withdrawn from the holes in the tie. WVhen it is desired to again adjust the guard rail, the clip is is reversed so that its flange la abuts against the lip z of baseplate 0 and the flange 7c overhangs the main rail flange, while the clip a is given another quarter turn.

In place of the clip 7c, four clips may be employed, each similar in construction to the clip 1", but of different sizes, whereby the adjustments described may be effected by substituting one clip for another.

In the final adjustment, the clip is is given a quarter turn to bring its widest flange 70* against the lip z of the base plate 0, and its narrowest flange 70 over the main rail flange, while the clip 11 is given a final quarter turn to set it to its most forward position.

In the particular design shown, it is preferred to bevel off the corners of the clip a most remote from its bolt-receiving orifice to permit the clip to be turned between the webs (Z, cl, without wholly withdrawing the screw-bolts m from the ties.

Different expedients for holding the wedge h in position may be adopted. For ex ample, a series of holes 8 may be formed near the narrower end of the wedge and flared at one end, and in the hole nearest the web (Z, after the wedge is driven in place, may be inserted a pin or rivet t, which may be upset in the flared mouth of the hole.

A guard rail, supported and braced substantially as hereinbefore described, is well adapted to resist the most severe lateral thrust of the car-wheels. Both the guard rail and the main rail are entirely without bolt holes and there are no parts corresponding to the ordinary tie bolts that are likely to be ruptured under lateral strain.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
