Abstract: A feed control device for a drill press includes a case and a spindle unit extends perpendicularly through the case. The spindle unit includes a shank and a spindle which has a toothed portion formed to the outer periphery thereof. A depth detection unit is located beside the toothed portion. A driving unit is located at the rear end of the case and includes a motor and a belt which is connected between the motor and the shank. A feed unit includes a gear, a shaft and a feed handle. The shaft extends horizontally through the case and is perpendicular to the toothed portion. The feed handle is connected to the left end or the right end of the shaft of the feed unit so that right-handed or left-handed users can operate the feed handle. A control unit is electrically connected to the motor and the depth detection unit.

Abstract: A power transmitting structure for a band saw includes a first and a second shaft, and each of the two shafts has a plurality of gears engaged with each other so as to transmit a power of a motor with several sets of speed options. Each of the gears freely mounted to the second shaft has a notch defined in an inner periphery defining a central hole thereof. The second shaft has a third shaft movably received therein which is controlled by a control member connected to a knob. The third shaft has a pawl member pivotally disposed thereto in the second shaft which has a slot defined through a peripheral wall thereof so that the pawl member is selectably engaged with one of the notches. The second shaft has a toothed portion to engage with a rotating part to which a band saw member is connected.
