I-IOSEA XV. LIBBEY, OF BOSTON, MASSACHUSETTS.
RAILROAD-TIE.
SPECIFICATION forming part of Letters Patent No. 430,780, dated June 24, 1890.
Application tiled June 22, 1889. Serial No. 315,182. (No model.)
To all whom it may con/cern:`
Be it known that I, HOSEA W. LIBREY, a citizen of the United States, residing at Boston, in the county of Suitolk and State of Massachusetts, have invented certain new and useful Improvements in Railroad-Ties, of which the following, taken in connection with the accompanying drawings, is a speciication.
The object of my invention is to produce a' combined chair and tie for street-railroads that will be strong, cheap, and durable, and in rails to be used therewith, whereby the rails when sunken can be Yraised to the required level without disturbing the chairs and tie; and the invention consists in the particular construction of the chairs and tie, hereinattei1 fully described, and pointed out in the claims.
Referring to the accompanying drawings, Figure l represents a perspective View of a combined chair and tie, showing the rails in position. Fig. 2 is a vertical cross-section of the same. Fig. 3 shows the ends of two adjacent rails with elongatedbolt-holes.
I make the chairs and tie of one piece of cast-iron.
A A represent the chairs, and-B the tie, arched and otl 'I' lform, all cast in one piece.
The chairs are provided on each side with Ilan a, which rest upon longitudinal stringers O and are secured thereto by spikes b.
D D are the rails, which may have any desired form of head and are provided with a central rib d. This rib is et the same thickness throughout its depth and tits into a groove or recess e, formed in the chairs, which groove is slightly deeper than the rib. The outer portion of the chair, that comes under the tread d? of the rail, is slightly higher than the inner portion, that comes under the iiange d', so as to provide a firm support for the tread d? and flange d of the rail. The rib of each rail is formed with vertical slots or bolt-holes g at each end and at suitable distances between, according to the distance it is desired to have the chairs apart, and through the walls of the chairs are provided round bolt-holes, each boltE passing through the walls of the chair and through a slot g in the rail. The object ot' having the holes in the rails elongated is that should the roadway settle the bolts E can be loosened and `the rails raised to make the track level without disturbing the chairs and tie. A block of hard wood or other packing being inserted in the groove e under the rib (Z will hold the rail at the desired height. The bolts E are then tightened up, and all will be secure.
Between the outer portion of the chair and flange o a rib may be cast in the center to give greater strength, or instead of a single rib in the center a small iiange might be formed at the two outer edges.
In Fig. l I vhave shown one chair supporting the ends of two ad,`acen t rails D D and the other chair as supporting the central portral portion ot a rail D and secured by two bolts; but one bolt only need be employed.
It will be seen that by this construction, the
tie and chairs being cast in one piece, a roadway can readily be constructed, and the gage will be the same throughout. The level of the rails can be maintained without materially disturbing the roadway, and the cost ot' constructing and maintaining the track will be comparatively small.
NVhat I claim as my invention isl. In street-railroad construction, chairs and tie all cast in one piece, the chairs having vertical parallel grooves and suitable bolt-holes, in combination with rails having a rib in which are formed vertical slots or elongated bolt-holes, the said rib fitting the groove in the chairs, which groove is somewhat deeper than the rib on the rail, whereby the rail can be adjusted, substantially as set'forth.
2. A rail for street-railroads, having a rib ot' equal thickness throughout and provided with elongated bolt-holes, in combination with a tie and chairs consisting of two chairs connected by an arched tie-bar of T form, all cast in one piece, each chair having a vertical parallel groove to receive the rib of the rail and provided with suitable bolt-holes, the outer portion ot' the chairs being higher than the inner portion, all substantially as and for the purposes set forth.
In testimony whereof I have signed my name to this speciiication, in the presence of two subscribing witnesses, on this 29th day of May, A. D. 188).
