Definitions

  • This invention is based upon the known fact that when Wood, hemp, flax, and other vegetable substances are heated in Water at a temperature at which it boils under a pressure of several atmospheres the gummy and coloring matters by which the fibers are held together are dissolved, or at least so much,
  • the invention consists in effecting the separation of the fibers of such substances by whippin g, beating, rubbing, grinding, or picking them while they are exposed to the action of water at such temperature and under such pressure as above mentioned.
  • a A are two upright trunks, of cylindrical or other form and of similar size, connected at their bottoms by a horizontal trunk B, which constitutes the casing of a mill, and at their -to a grinding or rubbing action.
  • This cone is secured firmly upon a central horizontal shaft E, which passes through stuffing-box bearings a a in the lower parts of the cylinders A A', and the said shaft has secured to it on opposite sides of the cone D two series of obliquely-arranged blunt-edged blades b b and b b', which operate as beaters for beating the substance under treatment, and also with a screw-like action to cause the substance to be fed from the trunk A to the mill B D, and from the said mill to the trunk A.
  • the portion of the shaft E which passes through the trunk A may be solid; but the portion which passes through the trunk A is hollow and is perforated at c c to communicate with the interior of a conical screen F, which is united with the shaft and grindingcone D.
  • the latter portion of the shaft is also perforated at d outside of the trunk A to communicate with the interior of a stationary box G, which surrounds the said shaft, and which should be packed around the shaft with a stuffing-box at each end.
  • This box is for the escape of Water from the apparatus, and has attached to it an escapepipe e.
  • This pipe e is surrounded by a jacketpipe f, through which fresh water is supplied to the apparatus, the said jacket having 4a pipe h leading from it to the bottom of the trunk.
  • This pipe h has connected with it a steam-pipe t' for the introduction to the apparatus of steam from a boiler suitably arranged.
  • the operation of the apparatus is conducted in the following manner:
  • the bonnet of. is removed and the trunks A A filled or partly filled with the substance to be treated, which, if it be wood, should be cut or split into sticks and free from knots.
  • the apparatus is then filled up with water through the pipes f h, the bonnet a* put on, and the water heated up to a temperature of from SOOo to 400 Fahrenheit by theintroduction through the pipes t' and h of steam at suitable pressure.. After the water has stood at this temperature fora few moments the gums will have been softened sufficiently, and rotary motion is coinmunicated to the shaft E to set the grindingcone D and beaters b b b b infoperation.
  • the beaters feed the substance under treatment to the grinding-cones D and carry them away therefrom, and While the beating and grinding proceed the said beaters produce a circulation of the whole of the Water and solid matters through the apparatus in the direction of the arrows shown in Fig. 1, causing all parts of the substances to be repeatedly subjected to the beating and grinding-operations.
  • the proper temperature in the apparatus is kept up by the continued introduction of steam at the pipes 'L' h, and while pure Water is allowed to flow in continuously through the pipes f h the Water charged With gums and coloringmatters is allowed to escape through the screen F, hollow shaft E, box G, and' pipe e, the screen being prevented from being choked up bythe fiber by the centrifugal force given to the latter by the rapid rotary motion of the screen and beaters.
  • This operation is continued until the Water escaping at e becomes nearly clear, when most ot' the guinmy and coloring matters will have been washed from the fibers. The heat carried off by the escaping Water will be to a great extent saved by the introduction of the incoming pure Water through the jacket-pipe f.
  • An apparatus operating in all essential respects the same as that described may be heated to raise the temperature of the Water to the desired degree by the direct application of iire to its exterior.
