Bramah's Planing Mae'finery. by meansof a greater or less quantity of the the end ot the shaft and the bottom of the step. This device I deem of great conse chinery where massy and heavy loaded up following manner ; that is to say the lower part of the shaft must be turned perfectly smooth and cylindrical to a height something pressed when in use. This part of the shalt I immerse or drop into a hollow cylinder which fits its circumference near enough to ted to prevent shake. This cylinder I call the shaft above mentioned so that when the point of the shaft rests upon the bottom of the cylinder the parallel or cylindrical part may be sometimes above the top as upper end of the step cylinder. In the upper end of this of a double cupped leather or other materials surrounding the cylindrical part of the shaft in such a way as will cause the junction is passed through it and immersed in the part below the stuffing box ; then the pump fluid may be between its points and the bot depressed to any required point at pleasure by the alternate injection or discharge of the fluid used exactly the same as performed by time all friction will be avoided except that of the stuffing box which will be comparative ly trifling to that which would result from the reeling of such a shaft on the bottom of the step in the usual way. Thus will be gained the properties above stated ; and in addition theret I thin k it may be inferred that pro tight such a- shalt thus buoyed up by and aud turning in a proper fluid may continue working for years or perhaps hundreds of proper to apply.
