The raising or lowering of the oscillating frame,together with its rails (i i), is effected by the wedges(j f) acting upon the transverse connecting pieces (/i A);aucl through the medium of the levers (A and [) androds ( n ) either end of the rails (i i) may be depressed,and made to meet and rest upon the permanent rails(a a) of the line.
On the carriage being received upon the rails (i i) ofthe oscillating frame, the oscillating frame must bebrought into the horizontal position by means of thewedges, and after the truck and its load are removed tothe desired line of rail, the carriage may then, by thesame means, be allowed to descend upon those rails ineither direction, as required.
In figs. 3 & 4, a, a, a is a section of rail on the main lineof way; b, is the girder upon which the rail is fixed;c, is a sliding beam, the top surface of which is planed,so that by the lever (7) and the wedge-shaped bearings(d), this sliding beam may be raised in contact with theunder and planed side of the girders (A), whereby the
platform is made rigid. When the platform is required tobe turned, the sliding beam is lowered by the lever (7),and the platform is left to turn upon the friction pulleys(e e), two of which are shown in fig. 5.
