Abstract: A cylindrical portion of the tool or workpiece is rotatably supported by two pairs of spherical rollers rotatably carried by two pairs of holders mounted on first and second upright supports secured to a bed. The second support is adjustable to change the spacing between the supports. The holders have screw threads for adjusting the spacing between the rollers. Alternatively, separate feed screws are provided for the holders. A drive belt is looped around the workpiece and around a drive pulley rotatably mounted on a movable carriage biased by a spring to tighten the belt. A knob is provided to rotate the drive pulley. The flights of the belt are pinched toward each other by a pair of guide pulleys and by a pair of rollers adjacent the drive pulley, whereby the upper loop of the belt is kept open and close to the location of the workpiece when it is removed. The carriage may be latched in a belt-loosening position by a swingable latching arm.

Abstract: Successively finished drills or other tools are ejected from a chuck into successive angularly spaced openings in a rotary turret, mounted on a carriage with a power device for reciprocating the turret into and out of an unloading position. A ratchet wheel on the turret is indexed through successive detented positions by engagement of the ratchet wheel with a pawl, as an incident to the reciprocating movement. The pawl is mounted on a stationary pivot and is biased into the path of the reciprocating ratchet wheel.

Abstract: The disclosed machine comprises holding means for holding a drill or other similar tool to be ground, first and second drive means for producing translatory movement of the holding means along rectangularly related directions, third drive means for producing the rotation of the holding means, a plurality of grinding units including grinding motors and wheels for grinding the tool, respective additional drive means for causing feeding movement of the grinding motors to bring the wheels into grinding engagement with the tool, swivel means for swiveling the holding means to present the tool to the respective grinding units, a keyboard for entering numerical dimensional values and parameters for controlling the drive means, a TV tube for displaying the values and parameters, a memory for storing the values and parameters, means for bringing up a series of questionnaire pages on the TV tube to prompt the operator to enter all of the dimensional values and parameters to program the machine, the questionnaires havin

Abstract: A hopper payout for various coin denominations is disclosed having a hopper, a rotary pin wheel, removably secured shelf wheel, and delivery opening in which the pin wheel is suspended for rotation by means of rollers oriented at the periphery of the wheel on spaced centers. The shelf wheel is removable and replaceable with differing diameter shelf wheels to accommodate varying denominations of coins. A centrally disposed agitator is similarly removable and interchangeable. The knife which removes coins from the shelf wheel is pivotally mounted to accommodate varying diameters of the varying coin dimensions. A uniformly widening coin gutter is provided to reduce the tendency of the coins to jam and shingle, irrespective of denomination and size.
