Description
WILLIAM NIERRIGK OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent No 105,354, dated July 12,1870.
Maom IMPROVEMENT IIN PREPARING PAPER PULP IOR PACKING- AND TRANSPORTATION.
The Scheme referred to in these Letters Patent and making part of the same,
I, WILLIAM H. MERRICK, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented anImprovementin Preparing Paper Pulp for Packing and Transportation, of which the following is a specification.
.chine, in order to facilitate the packing and transportation of the said pulp,
General Description.-
The manufacture of ,paper pulphas of late years becomeja speciality, and a separate business from that of converting pulp into paper, large quantities of pulp being transported from pulp-works to paper-makers in diiierent localities. In packing paper pulp for transportation it is important that it should be dry, or nearly so, and this drying has hitherto been eflected by the exposure of the pulp to air or 'to heat. In some cases the paper pulp, after bcing bleached, has been subjected to a machine for conversion into a thick sheet, which is rolled up for transportation,
In order to avoid the delay incurred by the ordinary process of drying pulp, or by converting it intosheets to be rolled up, I subject it, either before or after it is bleached, to the action of a centrifugal machine, such as is now generally used for drying clothes or draining sugar. The construction and operation of these machines are too well understood to need description or illustrative drawings. Before thc'pulp, however, can be subjected to a centrifugal machine, with good results, it is necessary that the fibres should be subdivided and held in suspension in water. Any suitable mixing ap pamtus may be employed for this purpose; an ordinary vat, for instance, with suitable stirring devices, may he used, the val: communicating, through a hole or spout, with the centrifugalmachine, so that the water holding the subdivided fibers in suspension may flow in a stream to the said machine, by which the water is rapidly discharged, leaving behind it a mass of dry or comparatively dry pulp, which can be at once packed for trmrsportation.
