After the large pipe P supporting the vane is firmly braced to the roof, and before the vane is attached to the rod, the contact friction rollers 0 must be placed in position. This will be done by raising the vane rod sufficiently to enable the circuit closer coco and friction rollers G to be slipped on the lower end of the rod. Lower the rod to its former position, so that the upper friction rollers (which.are immediately below the vane) will rest upon the cap of the pipe.
