The annexed engraving is a perspective view of an improved machine for mortising and boring the hubs of wheels, &c. The inventor is N. C. Travis, of Canistota, Madison Co., N. Y., who has taken measures to secure a patent for his improvements, which consist in giving a reciprocating motion to the mortising tool, and a rotary motion to the boring tool by the same tool stock. A is the bottom support of the machine and a a the posts; a hub is placed on the table below the mortising tool, R. This hub can be moved backwards and forwards on a slide by a screw working below: B is the driving axle, and C is the driving pulley which is kept continually revolving by a band from any prime motor; 0 is a clutch collar, and L is a disc on it to which is secured eccentrically a reciprocating arm, N, which is attached to a guide slide pin, b, and connected to the boss, 0. This collar is secured to the slide stock, K, by the screw, P"; R is the mortising tool or chisel, it is fastened.in the stock by a screw passing through the lower collar. Th clutch collar, O, which carries the eccentric plate, L, is made to gear with the shaft B, by a clutch on the other side, and not seen, but which gears the collar by simply sliding it horizontally inwards. The eccentric plate, L, will then revolve, and the arm, N, will receive an up and down motion at the top, which will give the stock, K, a vertical reciprocating motion, so as to make the tool, L, cut a mortise in the hub. This is the manner of working the mortising tool. It must be observed that the pinion, I, is loose like a collar around the shank of the stock, K, but it has a feather inside which gears into a slit in the upper part of the stock, when the upper spindle, H, receives a rotary motion. When it is desired to bore in the hub with an auger, the stock, K, must receive a rotary motion. This toolj R, is then replaced by an auger or bit, and the collar O, is thrown out of gear with the shaft, B, by the clutch spoken of before. The thumb screw, P, is also unscrewed, so that the stock, K, cannot be operated by a reciprocating motion through the plate. L, and arm, N. The band wheel, D, when the mortising operation is performing, is out of gear with the driving shaft, B, so that the pinion, J, is then stationary. To gi-ve the stock, K, a rotaiy motion, the band wheel, D, is geared to the shaft, B, by a clutch on the other side (not shown); this band gives motion to pulley, G, the horizontal spindle, H, and bevel wheel, I, which latter diives the pinion, J, and gives rotary motion to the stock, K, thereby making the tool bore out the hole in the hub. The pinion, J, rests in the stationary boss of the top plate of the frame; Q is a spring pressing on the head of the stock, and keeping it snug and free from vibration. Thus two motions are communicated to the stock,K, to actuate different tools and perform entirely dissimilar operations. This machins therefore combines the qualities of mortising and boring, the tool for the former operation having a reciprocating, and for the latter a rotary motion.
