 mm nm AUTOMATIC STACKING MACHINE FOR BARS AND THE LIKE This is a division of application Ser. No. 337,649, filed Mar. 2, I973.  
  This invention relates, as indicated. to an automatic stacking machine for bars and the like.  
  A primary object of the invention is to provide a machine of the character described having means for automatically accumulating single bars into a compact row or charge of such bars, to facilitate further handling of the bars.  
  Another object of the invention is to provide a machine of the character described embodying precharge carriages for transferring the charges onto a set of power-driven chains and against a set of stops for further compacting.  
  A further object of the invention is to provide a machine of the character described embodying stacking carriages for transferring the charges onto stacking cradles, in which the charges are stacked to form bundles which are strapped for shipment or storage.  
  A still further object of the invention is to provide a machine of the character described having magnetic turnover arms for transferring certain charges to the stacking cradles.  
  Other objects and advantages hydraulically my invention will be apparent during the course of the following description.  
  In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,  
  FIG. I is a plan view of the automatic stacker, with portions thereof at the right end of the machine omitted, due to limitations of space;  
  FIG. 2 is a fragmentary plan view, on a slight enlarged scale, showing several lateral chain transfers, precharge carriages, stacking carriages, and drives therefore;  
  FIG. 3 is a view similar to FIG. 2, but on a somewhat larger scale, showing one of the precharge carriages and one of the stacking carriages;  
  FIG. 4 is a side elevational view of the parts shown in FIG. 3, as viewed from the lower end of FIG. 3;  
  FIG. 5 is a side elevational view, on an enlarged scale, as viewed in the direction indicated by the line 5-5 of FIG. 3, of the stacking carriage, in extended position;  
  FIG. 6 is a fragmentary cross-sectional view, taken on the line 6-6 of FIG. 5;  
  FIG. 7 is a fragmentary bottom plan view, of the stacking carriage, as viewed in the direction indicated by the line 7-7 of FIG. 5;  
  FIG. 8 is a side elevational view, on an enlarged scale. as viewed in the direction indicated by the line 8-8 of FIG. 3, of the precharge carriage, in fully extended position;  
  FIG. 9 is a side elevational view showing the powered lateral chain transfer and magnetic turnover arm;  
  FIG. 10 is a side elevational view showing the fixed stop, disappearing stop, and power positioning stop;  
  FIG. 11 is a fragmentary cross-sectional view,talten on the line 11-11 of FIG. 10;  
  FIG. 12 is a fragmentary cross-sectional view, taken on the line 12-12 of FIG. 10;  
  FIG. I3 is a fragmentary cross-sectional view,.taken on the line 13-13 of FIG. 10;  
  FIG. 14 is a fragmentary side elevational view, as viewed in the direction indicated by the line 14-14 of FIG. 13;  
  FIG. I5 is a fragmentary cross-sectional view, taken on the line 15-15 of FIG. 10;  
  FIG. I6 is a fragmentary cross-sectional view, taken on the line 16- I6 of FIG. I0;  
  FIG. I7 is a fragmentary cross-sectional view, taken on the line 17-17 of FIG. I0;  
  FIG. 18 is a fragmentary cross-sectional view, taken on the line 18-18 of FIG. I0;  
  FIG. 19 is a fragmentary cross-sectional view, taken on the line I9-I9 of FIG. 22;  
  FIG. 20 is an elevational view, as indicated by the line 20-20 in FIG. I9;  
  FIG. 21 is a fragmentary cross-sectional view, taken on the line 2l-2I of FIG. I9;  
  FIG. 22 is a top plan view, showing one of the magnetic turnover arms;  
  FIG. 23 is an elevational view, showing the power stacking cradles, as viewed in the direction indicated by the line 23-23 in FIG. I;  
  FIG. 24 is a top plan view of the power stacking cradles, shown in FIG. 23;  
  FIG. 25 is a cross-sectional view, taken on the line 25-25 of FIG. 24;  
  FIG. 26 is a top plan view of the parts shown in FIG. 25;  
  FIG. 27 is a fragmentary view showing the shape sensor device in elevated or raised position;  
  FIG. 28 is an end elevational view of the shape sensor device in its lowered position;  
  FIG. 29 is a side elevational view of the stabililzer arm assembly;  
  FIG. 30 is an end elevational view of the stabilizer arm assembly;  
 FIG. 3I is an end elevational view of the disc brake;  
 FIG. 32 is a side elevational view of the disc brake;  
  FIG. 33 is a fragmentary elevational view of the adjustable side roll synchronizing shaft, as viewed in the direction indicated by the line 33-33 in FIG. 24, with portions broken away to show some of the driving elements;  
  FIG. 34 is a cross-sectional view, taken on the line 34-34 of FIG. 33; a

  FIG. 36 is a cross-sectional view, taken on the line 36-36 of FIG. 35;  
  FIG. 37 is an end elevational view of the tamping device, and  
 FIG. 38 is a side elevational view of the tamping device.  
  For convenience in understanding the invention, the stacker comprises various units or components, which may be generally described as lateral chain transfers,  
 precharge carriages, stacking carriages, turnover arms,  
 stacking cradles, fixed stops, disappearing stops, and power positioning stops. These, as well as several other components, will be separately described.
