Abstract
6712. Grimaldi, M. May 5. Point - tongues, mounting of. - Railway and tramway point tongues 1 of the kind adapted to rock from side to side upon a longitudinal axis are made of substantially rectangular form and mounted in a groove 7 formed by the rails 3, 4. Lateral extensions 19 are formed on the tongues, the width of which vary so as to produce a rail slot of uniform width. The heel 14 of the tongue is tapered and rounded off, whereby a vehicle wheel is enabled to throw the tongue over to the correct position.
