Saw cylinder assembly for a gin stand

Abstract

         8 . The saw cylinder assembly of  claim 6 , wherein the means for engaging with the driving source, on one end of the shaft of the asymmetrical driven shaft, is at least one drive keyway configured as a longitudinally-extending superficial groove on the one end of the shaft. 
     
     
         9 . A saw cylinder assembly for a saw-type gin stand comprising:
 a) a symmetrical driven shaft comprising (i) a shaft comprising two means for engaging a driving source, one on an end of the shaft and another on another end of the shaft, and (ii) two directional saw blade keyways, wherein each of the two directional saw blade keyways is an asymmetrical longitudinally-extending superficial groove on a central length of the shaft, between the two ends, the two superficial grooves positioned antipodal about the shaft; and   b) a plurality of directional circular saw blades each comprising (i) a central aperture comprising two directional keys and (ii) a plurality of saw teeth along an outer-periphery of each blade,   wherein the two directional keys are complementary in shape and position to the two superficial grooves of the driven shaft, for mating, and wherein the plurality of saw teeth have a preferred direction for function,   wherein, when assembled, the plurality of directional saw blades are mated with the driven shaft in only one orientation, and the plurality of saw teeth rotate about a common axis defined by the driven shaft, and   wherein the complementary shape and position of the two directional keys with the two superficial grooves preclude the saw cylinder assembly from being assembled with any of the plurality of saw teeth being orientated against the preferred direction for function.   
     
     
         10 .
