_Transmission._--The driving shaft, _k_, revolves in a pillow block, K, cast in a piece with the frame, B. It is usually actuated by a special motor, and carries a fly-wheel (not shown in the figure for want of space). It receives in addition a cog-wheel, L, which transmits its motion to the decorticating cylinder through, the intermedium of a large wooden-toothed gear wheel, L'. The shaft, _a_, whose diameter is 228 mm., actuates in its turn, through the pinions, M' and M, the pitch pinion, N, upon whose prolonged hub is keyed the pinion, M. This latter is mounted loosely upon the intermediate axle, _m_. Motion is transmitted to the driving shaft, _h_, of the endless chain, I, by an ordinary pitch chain, through a gearing which is shown in Fig. 12. The pitch pinion, N', is cast in a piece with a hollow friction cone, N squared, which is mounted loosely upon the shaft, _h_, and to which corresponds a second friction cone, O. This latter is connected by a key to a socket, _o_, upon which it slides, and which is itself keyed to the shaft, _h_. The hub of the cone, O, is connected by a ring with a bronze nut, _p_, mounted at the threaded end of the shaft, _h_, and carrying a hand-wheel, P. It is only necessary to turn this latter in one direction or the other in order to throw the two cones into or out of gear. If we allow that the motor has a velocity of 70 revolutions per minute, the decorticating cylinder will run at the rate of 50, and the sugar-cane will move forward at the rate of 12 meters per minute. This new machine is a very simple and powerful one. The decortication is effected with wonderful rapidity, and the canes, opened throughout their entire length and at all points of their circumference, leave the apparatus in a state that allows of no doubt as to what the result of the pressure will be that they have to undergo. There is no tearing, no trituration, no loss of juice, but merely a simple preparation for a rational pressure effected under most favorable conditions. The apparatus, which is made in several sizes, has already received numerous applications in Martinique, Trinidad, Cuba, Antigua, St. Domingo, Peru, Australia, the Mauritius Islands, and Brazil.--_Publication Industrielle._ * * * * * MOVING A BRIDGE.
