Definitions

  • the present invention relates to an improvement in barking drums of the type which consist of several substantially' hori 5 zontal V rotary-drum sections arranged e'nd toend; i
  • the barking operation takes place the cash- 1", the wetter the bark is, and it will of "course also be effected the speedier and better the greater the pressure between the logs is;
  • the present invention has for its pur pose to render it possible tofill the barking drums to a higher levelthanfhitherto pose ible, whereby several advantages areat tained amongst which arethat the wood is given more time in the barking drum and" thus becomes better soaked with water, and
  • the invention consists principally in that the drum sections, taken in the; direction from the inletend ofthe drum, lie' with their axes higher than the axes of'the" following drum sections or with their axes displ'aced to that side of the vertical plane through of a barking drum the sections of whichhave equal diameters, and'Fig. 2 is a diagrammatical end vieW of the drum.
  • Fig. 3 shows a longitudinal section of a barking drum the sections of which have unequal :diameters
  • Fig. 4 is a diagrammatical end view of said drum.
  • the laxisflA2 of the section 2,' and 5' also has itsaxis A1 displaced to the left of 'thegvertical plane- 1 through the axis A2 of ,thesection 2, that i is'to say on that side'of the vertical plane 6 .”
  • thefsection 1 lies with through said'axis A2011 which side the 'cir cumferences of the sections move; down- Wards, -as indicated by the arrow 10.
  • the varioussec- V tions are supported by chains 8 running over chain wheels 6 'onfshafts *7 and are also 'supported attheir ascending sides by' supporting rollers'9.
  • section in Figs. 1 and 2 higher than the preceding: section 4, and preferably also somewhat tothe left of the same, as shown.
  • a barking drum having an inlet end and an outlet end, the combination of several substantially. horizontal rotary drum sections arranged end to end, each drum section. having entirely open and unconstricted ends, the section nearest the inlet. end of a pair of adjacent drum sections having its axis located higher in the vertical direction than the axis of the other of said drum sections.
  • a barking drum having an inlet end and, an outlet end, the combination of severalsubstantiallyhorizontal rotary drum sections arranged end to end, the section nearest the inlet end of a pair of adjacent drum sections having its axis located higher in the vertical direction than the axis ofthe other of said drum sections and also displaced to that side of the vertical plane through the axis of said other drum, section on which side. the circumferences of the drum sections move downwards.
  • a barking drum having an inlet end and outlet end, the combination of several substantially horizontal rotary drum sections arranged end to end, the section nearest, the inlet end of a pair of'adjacent drum sections having its axis located higher than the axis 0t the other of said drum sections in the direction erpe ndicular to the slanting" level formed in the drum when rotated, andia drum section at the discharge end of the drum having its axis located higherthan the axis of the preceding drum section.
  • a barking drum having an inlet. end and, an. outlet end, the combination of sev eral substantially horizontalrotary drum sections arranged end to end, thev section nearest the inlet end of. a pair of adjacent drum sections having its. axis located higher than the axis of the other of said drumsections in. the direction perpendicular to the slanting level formed by the rolling'wood in the. drum when rotated, said drumsections being provided at their adjacent ends with exterior flanges adapted .tocover such portion of. the, end opening of one section as is not covered by the adjacent section.
  • abarking drum having'an inlet end andv an outlet end, the combination of several y the rolling wood substantially horizontal rotary drum sec--v tions arranged end. to. end, the. section nearest.- the inlet. end of. a pair of adjacent drum sections having its, axis. located higher in the vertical direction than the axis of the other of said drum sections, said drum sections. being provided at their adjacent ends 'with exterior flanges adapted, to coversuch portion: of the end opening or one section as is notcovered by the adjacent section.
