TO OPERATE THE EXTRACTOR. 



Fig. 1 shows the driving mechanism with 

 the cam-lever turned down in a horizontal 

 position. Fig. 2 shows this lever pushed ui> 

 to a vertical position, in which case the 

 cross-shaft and disc are crowded to the left 

 so that the disc is in contact with the paper 

 pullej' on the reel-shaft, thus causing the 

 reel to turn. There is only one adjustment 

 necessary, and that is the position of the 

 collar on the horizontal cross-shaft of the 

 extractor, which receives the thrust from 

 the spring when the cam-lever is in a verti- 

 cal position. Fig. 2 shows this collar and 

 the set-screw that must be loosened when 

 the position of the collar is changed. If

position, the tension is released automati- 

 cally by the shape of the cam to relieve 

 unnecessary strain on the bearings. A very 

 slight pressure on the i)art of the disc 

 against the i^aper wheel is sufficient to keep 

 the reel moving at high speed, when it is 

 once under motion; therefore the adjust- 

 able collar should not be located any closer 

 to the cam lever than is necessary to keep

this collar is too close to the cam-lever the 

 tension on the spring when the lever is in 

 the driving jDosition will be too great, caus- 

 ing an unnecessary strain on the bearing. 

 On the contrarj^, if the collar is too far 

 away from the lever there will not be 

 enough tension to drive the reel. 



It will be noted that the sliape of the 

 cam-lever is such that the greatest tension 

 on the spring (and conseciuently the great- 

 est thrust) occurs when the cam-lever has 

 been moved up about half way to the verti- 

 cal position. A little more tension is need- 

 ed at the start to get the reel speeded u]v, 

 but when the proper speed has been reached, 

 and the lever moved on over into the vertical 



the reel turning at full speed when the lever 

 is in a vertical position. When the adjust- 

 ment is correct the lever wnll turn up or 

 down easily, requiring verj' little effort. 



LOCATING THE MACHINERY AND TANK. 



Fig. 3 shows the arrangement of the 

 extractor, pump, engine, tank, etc., that we 

 r!Hommend. The outside door to the ex- 

 tractor room should be on the side nearest 

 the capping-melter or uncapping-tank, so 

 that the full supers will not have to be 

 carried about the room any more than i'* 

 absolutely necessary. All new belts will 

 stretch slightly at first, after they have beei' 

 run a short time. It is well not to locate 

 liie engine, i>ump, etc., too permanently at
