Disc C is provided with half coupling, C ; whenit is intended to engage or disengage motion, the hand-wheel G must beturned (or lever can be used), which, by means of right and left screws *John A. Hafner, Pittsburg, Pa. FRICTION CLUTCH. 197 forces the V-shaped coulter wheels, F F, between the discs C and D, thusseparating them and permitting the centre disc, B, to revolve freely. Thisreleases the power and stops the discs D and C, so that the half couplingH can be engaged with the extension of the ha
