A machine of the above description has been lately invented by Franklin Fruit, of Jeffsrson City, Mo., who has taken measures to secure a patent. Barrel heads are formed of several pieces, and these often vary in thickness, hence causing some difficulties in the process of chucking. The inventor has I overcome this obstacle by using a chuck of apeculiar description. It is made of two circular discs with a series ot centres placed in a circular form. Each centre is provided with a spiral spring, so that it can yield to accommodate the different thickness of the wood. All persons engaged ;n this great branch, ot manufacture will imuerstand that the chuck can be employed in conjunction with the usual shaping and bevelling apparatus.
