ter-clockwise rotation of the shaft—beingfrom left to right, and the return stroke from right to left. Theaverage cutting velocity is the velocity of the crank pin multipliedby the stroke B1B2 and divided by the length of the arc A1CA2;and the average return velocity is the crank-pin velocity… … Fio. 182. is the point of intersection of PA, produced, with the perpendicular •through B to the line of stroke, and consequently, as in theordinary direct-acting mechanism, if a line through P be drawnperpendicularly to the stroke to meet BA produced, if necessary,in N, then PN will represent the…
