The Civil engineer and architect's journal, scientific and railway gazette . a very , diminished. PADDLE-WHEELS. Thomas Hint Bakber, of King-street, Cheapside, London, gen-tleman, for in machiiifry fur pr(ipi://iiiy vessels.—Granted October 7, 1847 ; Enrolled April 7, 1848. This invention consists of an arrangement or combination ofparts into paddle-wheels for propelling vessels. The external caseof the wheel is a cylinder, which is fixed to and revohes with thedriving-axle; and the floats are so arranged within the cylinder,as to be projected outwards when required to act, and are againwithdrawn into the cylinder as they go out of action ; such con-struction of paddle-wheel allowing it to be wholly immersed in thewater. To govern the action of the floats, the patentee prefers touse a cranked axis, one end of which enters into the main ordriving axle. On to the main-axle is placed a boss, to which armsare attached, for holding firmly the floats. The annexed diagram,which is a side-section of the paddle, will explain the manner in. which the floats are intended to act. The cylinder i, b, has asmany slits or openings through it as there are floats to the wheel;and within the cylinder are angular hollow vesselsy;/ which givebuoyancy to the wheel, aiul also serve for the purpose of oftering in-clined guiding surfaces to the floats as they are moved arms/t, A, are attached by pin-joints to the boss or collar onthe crank axis ; and to the ends of the arms the floats are to be floats i, i, i, are represented to be in action, whilst the othersare drawn within the cylinder. The patentee says, that althoughhe prefers to use a cranked axis for governing the action of thefloats or paddles, it will be evident to an engineer that an eccen-tric might be siibstituted and produce a like result ; and it willalso be evident that in place of having the floats or paddles whereonare arms or spokes governed or controlled liy a crank or
