SPECIFICATION forming part of Letters Patent No. 532,364, dated January s, 1 895. Application nea February 15,1894. sean No. 500,194. (No moda.)

struction, along with like facility and security of attachment of the rails.

In the accompanying drawings, I show in Figure 1 a perspective view of my invention as applied in practicef Fig. 2 is a transverse section of the same. Fig. 3 is a horizontal section. Fig. 4 is a vertical section on line 4-4 of Fig. 2. Fig. 5 is a perspective view ofthe device for fastening the bolts that clamp the rail in place.

The tie, A, is channeled or trough-like, bein formed with a flat base and vertical, parallel, side flanges, ct af. Nearv each end of the tie is located a rail-support, or chair, B, which has the same cross-section andheight as the tie, but is of less width, and inverted in position, so that its side flanges b, b, t closely against the flanges a, a, of the tie, as shown. 'Ihe chair is permanently and rigidly secured to the tie by means of rivets, c, which pass through the flanges, a., b, and are upset on the outersides of the respective parts. The flanges b, b, of the chair rest directly upon the base ofthe tie, A, and, the two being likewise riveted together and produced from wrought or rolled steel plates, it willvbe seen that the rail-support thus formed combines in an eminent degree the qualities of strength, rigidity and lightness of construction so desirable in this class of devices.

In practice, the tie and chair are riveted t0- gether before leaving the shop, so that they practically form and are shipped and handled as one integral article.,

The track rails, C, are laid flat upon the chairs, B, and clamped thereto by means of clamps D, D, which have a general resemblance in form to the ordinary railway spikethat is to say, they have a flanged head', CZ,

and a straight polygonal body, which fits in corresponding, coincident, vertical holes or openings,b, and, a', formed in the chair and tie, as shown. There are two such holes in the chair and tie, and they are preferably arranged diagonally opposite.

. Each clamping bolt, D, has a transverse notch, orkerf, d', in its inner side, the same being formed at such distance belowy the flanged head, cl, that when the body of the bolt is inserted in place, it is just below the flat top of' the chair, B, as shown best in Figs. 2 and 4. When the bolts, D, are inserted in place, their notches, d', Aface each other and are adapted to receive a fastening which is a dat, sliding plate, E. Such fastening is inserted through horizontal slots, b2, formed in the flanges, b, of the chair, at a point just above the flanges, a, of the tie.

By preference, I construct the bolt-fastener,

E, in wedge form, that is to say, slightly tapered from one end `to the other, so that it may be driven tightly and will take up any slack or wear of the flanges of the bolts, and thus always hold the latter tightly clamped upon the base flanges of the rail, C. For this purpose, the notches, d', in the bolts are made wide enough to accommodate the greatest thickness fof the fastener, E. j v

In laying a track, the combined ties and chairs having been properly laid upon a suitably prepared road-bed, the rails C, are laid on the chairs, B, and the clamping bolts, D, then inserted in the 4coincident holes b', ot', with their head flanges, d, turned inward, so that, when forced down to place, theV saidI Hanges overlap and bear upon the flanges, a2, of the rail, as shown. It will be noted, that the lower ends of the bolts project into or through theholes, 0.', in the base of the tie, and are thus always held vertical. The fastener, E, is then driven into place, and locks the clamp rmly upon the rail flanges, thus securing the rail firmly against lateral movement. To preventthewedgefastenerbeingac- (Figs. 3 and 5) with one or more slits near its side edges, thus forming tongues e, that may be easily bent or twisted laterally. When it is desired to remove the rails, C, for any purpose, the said tongue is turned backinto pareidentally displaced, I provide its thinner end allelisin with .the body of the fastener, and the latter then driven out of the chair, or else detached by leverage of a crow-bar, which is engaged with the shoulder, or lug, e', Fig. 1 formed on the head of the plate. Such lug may also serve as a stop to prevent the plate, E, being driven too far, in case the latter is not made Wedge-like or tapered.

For use on curves of greater or less radius, the ties and chairs Will be provided With boltholes located at proportional distances, and special clamping bolts will also be provided, which will have kerfs or notches located farther from the flanged heads than shown in the drawings in order to accommodate the rise of one side ot' the rails due to tilting the latter inward.

l. The improved tie and rail'fastening vcomposed of the channeled tie, the flanged inverted chair permanently secured thereto, and both provided with coincident bolt-holes and one of them with lateral' slots, as specified, the flanged and notched clamping bolts, and a detachable locking device adapted to engage said bolts, substantially as shown and described.

2. As an improved article of manufacture,

the metallic tie and chair, the'same being- 4with lateralslots and vertical bolt holes which are coincident with other bolt holes in the base of the tie, as shown and described.

3. The combination With the chair having vertical bolt-holes and lateral slots, of iianged and notched rail-clamping bolts and a fasten' ing device which is inserted in said slots and engages the notches in the bolts, as shown and described.

4. The combination with the tie and chair secured together, and the latter having bolt holes and lateral slots, of rail-clamping bolts having flanged heads andside notches, of a fastening Which is in the form of a thin, tapered'or'Wedge-shaped plate adapted to enter said slots and the lnotches in the bolts, and thereby lock the sa-me in place, as shown and described. l
