RAILROADRAIL A-ND CHAIR.

STPECIFICATION formingpart of Letters Patent No. 412,637, dated October 8, 1889. Application filed December 17, 1888. Serial No. 293,787. (No model.)

To all whom it may concern.-

, street-railroad rail and chair whereby the rail can be adjusted, when required, to level the 3 track without interfering with the sleepers or stringers; and the invention consists in constructing the rail with a central corrugated flange and a chair made in two parts and provided with corrugations to correspond to the corrugations of the flange, said flange being provided with slots through which pass the bolts for securin g the chair and rail together,

, so that when it is desired to raise the rail the bolt or bolts can be loosened, the rail raised to the required height, and the bolts again tightened up, so as to securely hold them together.

Referring to the accompanying drawings, Figure 1 is a perspective View representinga section of a rail and a chair embodying my invention. Fig. ,2 is a side view of a double chair to be used at the joints of the rails for connecting them together. Fig. 3 is a section through the rail and chair showing the rail partly raised. l

A represents a street-railroad rail of any desired form of tread and provided on its under side with a corrugated dependent flange B, provided at suitable intervals with vertical slots 12. The chair I make in two parts 0 C, the upper inner faces a, that are adjacent to the rails flange B, being corrugated to correspond with and fit the corrugations of the l flange ot' the rail, and are also provided with bolt-holes, and the lower portion a of the chair are turned out to form bearing-surfaces to rest upon the sleepers or stringers, to which they are secured by ordinary spikes or squareheaded bolts passing through oblong holes or slots (1, formed in the bearing part c.

To secure the rail and the chair together a bolt or bolts f are passed through the boltholes in the upper portion of the chair and through one of the slots '1) in the flange B of the rail.

It will be seen that by this construction of rail and chair that when they are bolted together they are as firm as if of one piece of metal, and should the road-bed sink the rail 7 can be raised up, as shown in Fig. 3, to the proper level without interfering with the sleepers or stringers and also without packing.

The object of-having the slots or oblong holes for the holding-bolts to pass through is that the rails can be readily adjusted to the required gage or the entire track shifted over a short distance without taking up and relaying the same.

What I claim as my invention is- 1. A railroad-rail provided with a corrugated flange having vertical slots at suitable intervals, substantially as and for the purposes set forth.

2. The rail A, provided with corrugated flange B, having vertical slots b, in combination with a chair formed in two parts 0 C, their upper inner faces 0 being corrugated to correspond with the flange of the rail, and their lower ends 0 provided with oblong holes or slots 01, substantially as shown and described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 22d day of November, A. D. 1888.

. I-IOSEA WI LIBBEY.
