The upper part of plates is formed as an arc, in the lower part of plates wavy grooves are made having crests and troughs, and it is smoothly connected to the lower surface of the side part and the mount is a frame made of a plate with corners welded to its bottom and reinforcing ribs, which is disposed longitudinally and has on the end surface of plates grooves for connecting to the drum of rattler. |
