| 6 | Bar Feeding Device | US15605467 | 2017-05-25 | US20170259343A1 | 2017-09-14 | Karl-Heinz Schumacher |

| 7 | Bar Puller | US14201731 | 2014-03-07 | US20140255129A1 | 2014-09-11 | Daniel R. Kenner |
| In a bar puller, pins mount serrated rollers to pivoting arms, which are mounted by additional pins to a bar puller body. The body houses movable cups positioned to compress springs in response to pivoting motion of the pivoting arms. A cover retains the springs and cups in the body. In a manufacturing process where elongated stock material needs to be positioned automatically, such as in a CNC turning center, the bar puller manipulates the elongated material in the machine by holding it rigidly so that the bar puller can move the elongated material on the axis of elongation. This is accomplished by forcing the end effectors over the material, which separates the end effectors by pivoting the arms. The geometry of the pivoting arms causes interaction with the cups and springs to generate an opposing spring force to separate the end effectors. | ||||||

| A process and apparatus for centering accurately and speedy a workpiece on a magnet chuck mounted on a work spindle. A pair of action pads spaced away from one another comes into engagement with the workpiece attracted to the work spindle, thereby performing the centering operation. The action pads are mounted on a support plate that can freely turn on a fulcrum. As the fulcrum makes head towards a rotational center of the magnet chuck, the action pads comes into abutment in a rocking manner against the workpiece that is held at off-center relation in the chuck, thereby compensating the off-center relation to keep a center of the workpiece in alignment with the rotational center of the chuck. | ||||||

| A simple wire probe is positioned between work stations of a multi-spindle automatic screw machine so that, when the spindles of the machine are indexed, the probe is contacted by the distal end of a properly-sized workpiece and a signal is sent to a conventional programmable logic controller ("PLC"). At the initiation of each cyclical indexing of the machine's spindles, an electronic timing "window" is opened in the PLC and, so long as the signal is received from the probe while the timing window is open, the PLC permits the machine's cyclical operations to continue. If, however, no signal is received during the preset time interval, indicating a "short part", the PLC is programmed to stop the machine drive and to provide a sensible indication (e.g., a flashing light) to call to the attention of the machine operator. The location of the probe does not limit the normal use or operation of any tool at any work station of the machine. | ||||||

| 20 | Method of and apparatus for feeding nonround-section bars to screw machines | US709284 | 1976-07-28 | US4068545A | 1978-01-17 | Holger Scheler |
| A screw machine has a headstock provided with an openable and closable chuck rotatable at high speed and having a throughgoing aperture of cross-sectional shape complementary to that of a bar to be machined in the screw machine. A feed apparatus for this machine comprises means for detecting the rotational speed of the chuck and for generating a speed output when the rotational speed lies within a predetermined range. In addition, a pusher is provided which only advances the bar into the aperture of the chuck after generation of the output. This pusher is engageable with an abutment that is only displaced out of its way when the speed output is generated. Furthermore the apparatus generates a position output when the bar is properly in place and has a timer which withdraws the bar from the chuck if within a predetermined time limit after generation of the speed output the position output is not generated, indicating that the apparatus is unable to load the bar. | ||||||
