Abstract
The moving means is for use in moving an operative member between an out-of-the-way position and an operative position by a movement having a linear component in a vertical direction and a rotary component about a vertical axis. A first shaft on which the operative member is mounted is movable vertically by a first piston and cylinder assembly and is in driving connection with a second shaft relative to which it can move vertically. A second piston and cylinder assembly is operable through a screw-threaded connection to cause its piston to rotate thereby rotating the second shaft and hence the first shaft about the vertical axis.
