RAILROAD-TIE AND RAIL-J'bINT.

I Specification of Letters Patent. Application filed July 8, 1901. Serial No. 382,627.

Patented Feb. 2, 1909.

To all whom it may concern:

Be it known that I, CHARLES JENKINS, a resident of Aspinwall, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Railroad-Ties and Rail-Joints; and I do hereby declare the followin to be a full, clear, and exact description t ereof.

This invention relates to railway track structures, and especially to a metallic tie and means for securing the rails thereto and also forming a joint for the meeting ends of.

ralls.

The invention comprises the construction of tie and rail supporting and clamping means hereinafter described and claimed.

In the accompanying drawings Figure 1 is a side viewof a portion of a railway track structure embodying the invention; Fig. 2 is a transverse section through the track on the line 22 Fig. 1; Fig. 3 isa similar view taken on the line 33 Fig. 1; Fig. 4 is a similar section taken on line 44 Fig. 1; Fig. 5 is a perspective view of one of the double ties; Fig. 6 is a similar view of one of the chairs used between double ties; Fig. 7 is a similar view of one of the single chairs; Fig. 8 is a similar view of a rail clamping member used at a rail joint; Fig. 9 is a similar view of the member used intermediate the rail joints; Fig. 10 is a perspective view of a single tie; and Fig. 11 is a similar view of the bottoms of the rails at the joint.

The cross ties embodying my invention are of inverted trough shape and are formed preferably of pressed plate metal. At the rail joints double inverted trough shaped ties '1 are used while intermediate the joints single ties 2 are used. Fig. 10 shows the single tie having the horizontal top portion 3, side portions 4 which are slightly inclined from the vertical, and outwardly projecting horizontal bottom portions or. flanges 5, while Fig. 5 shows thedouble tie used at joints, this having the same top, side and bottom ortions, with the intermediate horizonta bottom portion 6 joining the two trough shaped members. Since the side portions 4 are slightly inclined from the vertical and the tie is made of pressed re'-' silient metal, it will yield to some extent, so as to give largely the effect of a wooden tie and avoid the extreme rigidity of most metal ties, which is an objectionable feature. To reinforce and strengthen these yielding members it is preferred to connect the bottom flanges at one or more points between the rail seats, such as by means of a band or strap 7 provided with hooked ends embracing the flanges 5 of the tie, the drawing showing one such strap located at the central portion of the tie. This makes the tie ap roximately rigid or stifl at its center but eaves the bottom edges free underneath the rails so that it will spring or yield slightly under the impact of the train.

The tops of the tie are pressed down slightly as shown at 9 to form seats for the base of the rail, such depressed portions being of a depth'ap roximately equal to the thickness of the rai base. The means for securing the rail to the tie comprises a chair or chairs 10 and clamping members 11. The chairs are each formed of plates pressed to shape and are substantially inverted U- shape, with outwardly projecting horizontal flanges 12 resting upon and secured to the bottom flanges 5 or 6 of the tie, being shown as secured thereto by'means of rivets. If desired bolts may be used. The legs 13 of the chairs are provided about midway with horizontal flan es 14 which have upwardly projecting shou ders 15 at their edges. The ower portions of the legs flare outwardly slightly so as to make the chairs slightly yielding, or springy. The chairs used at the single ties, and at the outer sides of the double ties have plane tops as shown in Fig. 7, while those used betweenthe double ties have broad tops as shown in Fig. 6, with shoulders 16 at their side edges to embrace the edges of the rail base. They also have a rib 17 or boss on the upper face to take into holes or grooves 18 cut 1n the bottom of the rails, (Fig. 11) in order to prevent any lateral deflection of the ends of the rails at the joints. The chairs used between the members of the double ties have sloping side edges to fit into said space. Those used at the single ties need not contact with the rail base.

Theclamping members 11 are formed to embrace the edges of the rail base, having the portion 20 lying above the rail base and bearing against the web. of the rail and which may the rail base and having connected downzover the edge ofthe rail and projects 1' 2 into the depression 9 of the tie. The parts are secured in place by means of vertical bolts 25 passing through the horizontal flanges 14 of the vertical members of the chair and the horizontal flanges 23 of the clamping members, and horizontal bolts 26 connecting the vertical portions 22 of the two clamping members on the opposite sides of the rail and also passing through the upper part of the rail chair. The bolts 26 serve to draw the two clamping members on the opposite sides of the rail toward each other, thus tightly clamping the rail base and toreing the edges of the upper portions 20 of the clamps against the Web of the rail, while the bolts 25 passing through the horizontal flanges of the chair and clamping members hold the clamps against rising. The upwardly turned shoulders 15 on the rail chair largely relieve the bolts 25 of shearing strain. The bolts 25 and 26 have both right and left threads with two nuts 2 F which act to lock each other.

At the rail joints where the double ties are used there is a single chair used between the two members of the double tie, being secured to the bottom connecting portion 6 thereof,

and two chairs, one on either side of the tie,

and secured to the flanges 5. The ends 01" the middle chair are shaped to fit neatly against the vertical portions of the double tie and the top of the chair is flush with the rail seats so that the ends of the rails are sup ported on the chair. The clamping members in this case have the u )per portion 20 of sufficient length to extent over the entire double tie and have a vertical portion 22 extending down into the trough between the two members of the double tie, and one such portion at each side of the tie, being secured to the chairs in the manner described. At the single ties a rail chair 10 is placed on each side of the tie, being riveted to the flanges 5 at the opposite sides of the tie, and the clamping members 11 have a downwardly extending portion 22 on the op osite sides of the tie in the manner described with both forms of ties and clamping members the upper portion 20 embracing the base of the rail fits down into the depressed portion 9 of the tie.

The several parts of the track structure described can be easily and cheaply manufactured. No special shape of rails is required but any standard rail may be used. The two members of the chair and also the two members of the clamps can be readily made by die pressing, or forging, or castings may be used. The tie also can be conveniently made by die pressing, and all the parts can be readily assembled and when so assembled provide a track structure having a yielding ase similar to wooden ties and having the rails fastened to the ties in a very secure manner and also providing a joint for the rails without the necessity of using fish plates, or

lower edges of the trough intermediate the rail seats but leaving the edges free underneath the rails.
