The end of one'of these membersca-rri'esjthe bolt'31 "which extends through the forked end '32 of the ;other.member.and is provided with' an adjusting nut 33. By screwing in the nut 33,- the wedge members are moved 'over each other so that .their total thickness is. in-

'creased, thus moving the rail 4upward the desired amount. Clamping means areprovided in the form of the pairs of bolts '34 extendingthrough slots 35 in the clamping members and ,.through the flanges of the rail 4 and of the trackbeam 11. By the use aofthese devices, the track may be kept perfectly level at all times. i

Fig.8 shows a'modification of the track adjusting means inwhi'ch the circular wedges of Figs. (iand 7 are. replaced by the straight Wedges 36, 37 lying between the rails 4and track beamsllfl Bolts extending through the slot 38in the wedges and through the flanges of the rails and track beams serve to I lock the parts in adjusted position. Tables 5, 5 are locked tightly together as indicated in this figure, and a drain 'trough'39' is provided extending transverselyof the space 40 betweenthe cars in order toconduct away any abrasive which may penetrate between the ends of the cars, such trough discharging into the drain troughs 41 at the sides of the track. These troughs and the troughs 42 serve'to returnthe used abrasive which Theframework which supports themachines and tracks mayalso be utilized-as a I support for the rails 43, 43', which carry the inner ends'of'the cranes 44, 44, theother end I tion and removing them.
