TONGUE-RAIL FASTENING FOR RAILWAYS.
SPECIFICATION forming part of Letters Patent No.`655,444, datedAugust '7, 1900. Application filed J une 15, 1900. Serial No. 20,429. (No model.)
shall describe7 referring to the accom panying drawings.
Figure lis a plan, Fig. 2 is a longitudinal section on the line A B of Fig. 1, and Fig. 3 is a transverse section on the line C D of Fig. l, of part of a tramway-switch near the pivot of the tongue-rail.
a is the main rail; b, the end of the tonguerail; c, the guard-rail; d, the base-casting; e, the branchrail; f, the pivot of the tonguerail.
The base-casting d has slots g g', in which lies a key h in the position x 00, Fig. l, its one end being in the opening g of the basecasting. The pivot f of the tongue b is then inserted in the recess of the base-casting, and the key h is moved to the position x y and held by a key i, the key h beingthus driven into a slot 7c of the pivot f and lying with its one end in the opening g and its other end in the recess g under an overlapping part l of the base-casting d. In this way the tonguerail is prevented from rising.
The key t' being hard-driven into the basecasting, so that it is held by friction, effectually prevents the key 71 from being loosened, so that the tongue-rail cannot spring out of its position, and it is prevented from moving laterally by its strongpivot f in the recess of the base.
If the tongue-rail is to be changed, the key t by a lever applied to its gib mis withdrawn, and by means of a tool inserted at an opening fn the key 71, is moved from the position x y to the position a; :10,whe1eupon the tonguerail can be removed. As the pivot f and the recess for its reception are subjected to rapid wear owing to the lateral pressure of the wheel-flanges, it is of advantage to throw this Wear entirelyon the tongue-rail, which can be changed. For this purpose the rear part of the base-casting d is made of cast-steel and the sides of the pivot -recess are hardened, so that only the exchangeable tongue-rail becomes Worn.
The above-described construction allows of the removing and replacing of tonguerails and their fixing to be elfected without interfering with the roadway. The upper surface of the tongue-rail is very massive and strong, there being no bolt-holes through it, so that local hollowing is impossible. All parts of the fastening are keys, without any screwing or riveting, so that they can be easily loosened and replaced.
Having now particularlydescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is A 'fastening Afor a removable tramway ltongue-rail consisting of a cross-key engaged in a slot of the tongue-rail pivot, and having its ends held in aslot of the base-casting substantially as described.
In testimony whereof I have affixed my signature in presence of two witnesses.
PAUL KNITTEL.
