John Sitton, of Columbus, Miss., has taken measures to secure a *tent for the above. This machine, which the inventor denominates the " Wheelwright's Assistant," - is intended to pertorm the various operations of baring the hub, forming the tenons and shoulders of the spokes, and also holing the felloes. An important improvement is in the use of two circular plates, one lying on the other, and capable of revolving. These plates serve for regulating the distances between the spokes, as the top one carriE! the hub while being bored, and the wheel when the tenons are being cut. This arrangement, when fixed for boring, 'c., is held in position by pins acted on by springs. The auger carriage moves back and forth on an adjustable way or bed, which can be fixed to suit different-sized wheels, the carriage is made to advance by means of a cord and weight, and is drawn rapidly back by operating a treadle. The tool for cutting the tenons and shoulders of the spokes is of a peculiar shape, and acts more perfectly than other tools, both for cutting and also regulating the depth of the tenons and also tor squaring the shoulders. An adjustable bench for boring the felloes upon, can be attached or removed as required, this is furnished with an arrangement for holding the latter, and is so contrived that the bench need not be shifted when the end ef the felloe is ta he bored, but merely a movable pin. In addition to all these improvements there is a neat mode of regulating the size of the wheels by an index plate properly fixed.
