Shipbuilding in iron and steel / a practical treatise . . he balanced rudder, while adding very greatly to theships manoeuvring power under steam, tends to destroy the shipsway when she is tacking, and causes her occasionally to miss details of the arrangements of the rudder of the Herculesare given in side view and sections in Fig. 198. The two parts ofthe rudder before and abaft the axis are separately built, and areconnected by pintles and braces, the braces being forged on theafter edge of the fore part and the pintles on the fore edge of theafter part. From the sketches it will be remarked that the forepart has its frame formed in one forging, while the after part hasits frame made up of a forging and a bent plate, with two verticalframes intermediate between the fore and after edges. The afterpart is sided uniformly throughout, but the fore part is tapered insiding, as shown in the sections, the reason for this difference beingthe same as has been given for a similar arrangement in the 256 Rtidders. Chap. XIII. rn PIAA/ Fig 193. Chap. XIII. Rudders. 257 Bellerophon, The heel of the rudder is steadied by the after endof the keel j)iece, and the lower pintle on the after piece of therudder passes through a brace welded to the frame of the forepiece, and through a hole in the keel piece. The after piece ofthe rudder is attached to a solid iron rudder head, very similarin form to that of the Bellerophon, its lower end being con-nected with the forged frame by hook-scarphs, as shown in the sideview in Fig. 198. The fore piece of the rudder is attached toa tubular rudder-head at the lower end of which there is formed anarm that clasps the upper part of the frame. The solid rudder-head attached to the after piece passes up through the tubularrudder-head, and its upper end is steadied by a socket, workedbelow the main deck, similar to that fitted in the side view of the rudder, &c., shows how the weight of therudder is taken inboard on
