When the lever and cone are pressed forward the dogs ride up on the cone and press against the discs, thus forcing them together and making the entire case, drums and shaft revolve as one solid piece, thus giving the forward motion. With the lever in the middle the discs are free to revolve and no motion is transmitted. When the lever is drawn back the friction-band, H, is tightened on the drum and, being attached to boat or engine, the drum is thus prevented from turning while the motion is transmitted in a reverse direction through the spur-gears K. This is a powerful, strong and simple style of gear and is the form most widely used although practically every maker has some particular method of controlling the frictions or some special form of gears, but in general the principle is identical. OPERATION OF REVERSE GEARS The Baldridge Gear Company gives some valuable instructions regarding the installation and operation of their reversegear that are of interest to motor-boatmen. Excerpts are given because they apply to other gears as well. In the first place the user will find it economical to purchase a gear of sufficient capacity not only to handle the power developed by his motor, but also big enough to control the weight of hull and to handle the proper size propeller wheel with which his craft should be equipped for the class of service intended. A reverse gear of insufficient capacity is an expensive proposition in the long run regardless of its make or type. If the mechanism is not big enough for the outfit, the adjustments will have to be set up so tight as to make the operation of the controlling lever stiff and awkward and the whole outfit wil...
