CHRISTIAN ESSER, OF WIENER-NEUSTADT, AUSTRIA-HUNGARY, ASSIGNOh,
BY MESNE ASSIGNMENTS, TO PILGR'IM PAPER COMPANY YORK, N. Y., A CORPORATION OF MAINE.
Original application filed October 31, 1901. Serial No. 71,495.
To all whom, it may concern:
, Be it known that I, CHRISTIAN Essen, a citizen of the Empire of Germany, residing at Wiener-Neustadt, Lower Austria, Empire of Austria-Hungary, have invented a certain new and useful Method for the Production of I-Ialf-Stufl from Peat-Turf, of which the following is a specification.
My invention relates to certain new improvements in the method or process of reducing peat-turf to half-stuff; and it consists of the various steps and operations hereinafter more particularly described.
In order to thoroughly understand my in- IS vention, it should be understood that peatturf consists of partially-decayed vegetable growths-such mosses, ferns, grasses, and the like-which have died down and been submerged by the water of the bog wherein 2 the have been growing and that these vegetable growths are com osed of a fibrous skeleton or framework 0 cellulose embedded in and surrounded by softer vegetable matter. The cellulose or fibrous portion of the 2 5 plantis the part usually employed in the manufacture of the finished product. In the formation of peat these vegetable growths or I plants after being submerged for some time are attacked by the oxygen in the water, and decomposition gradually takes place, the
softer vegetable matters yielding to this attack first and the harder ii brous cellulose last. In its natural state, however, the cellulose consists of bundles or groups of fibers adher- 3: 'ing more or less strongly together, and these bundles must be reduced and the individual fiber separated before they can be used in the manufacture of paper or paper-board.
Some methods hitherto known for the pro- 40 duction of half stuilf-that is, the separation of the individual '[ibersare based on chemical treatment, and these give rise to the objection that the finer or individual fibers are destroyed or hopelessly injured if the action J, 5 of the process is allowed-to continue until the bundles or larger ones have been suflicicntly reduced, and in such a case it usually ha ens that during the further treatment (ii kali treatment) inmaking the half-stuff into aper the useless fine particles of cellulose tfius roduccd settle. and form an impervious ayer at the bottom of the sieve and are, moreover, incapable of felting owing to their mi- Specifieation of Letters Patent.
F HALF-STUFF FROM FEAT-TURF Patented Nov. 13, 1906 Divided and this applioation filed December 2,1901. saw (Specimens-l nuteness. Not only is the slu gish out-flow of the water thus produced the irect cause of the slow speed of the mill, but the article so produced is altogether of low qualityby reason of the faulty felting capacity of theseminute particles in the half-stuff.
It should of course be understood that in the natural production of peat the decompo sition which takes place is far from uniform, the smaller fibers or bundles of fibers offering less resistance to the decomposin action than the larger ones and are there ore rendered far more tender and susceptible of destruction or injury.
It is the object of my invention, therefore, to obtain the necessary reduction of fiber and the separation of the bundles thereof into their individual constituents without injury to the finer and more tender fibers and at the same time in a more satisfactory manner; and, broadly s' eaking, the invention consists in loosening t e fibers from each other by rubbing or other mechanical action, so that the bundles are disintegrated, while the finer articles are uninjured in any way, but are by the same operation provided with a rotective coating or retaining means, as wi be hereinafter more particularly described.
Various means may be used in carrying out my invention; but one machine which I have found well adapted for my purposes is that described in United States Letters Patent No. 690,363, issued to me on December 31, 1901, of which this application is a division, and wherein the bundles of fiber of the peatturf are reduced and separated by the action of reciprocating Stampers upon said peat, which is carried by a'tablc or platform constantly moving beneath the said stampers and at substantially right angles thereto, whereby a rubbing, tangential, or massaging action is produced, completely disintegrating the coarser fibers or bundles of fiber.
In practicing my invention ,the peat-turf, in its natural spongy moist condition as it comes from the bog 1s spread upon the table in a layer of the desired thickness, and the table is then started in motion. The reciproeating stampcrs are also u't in motion and strike the moving layer 0 peat, crushing the bundles of'cellulose and se mating the indi- The 111 the peat of course.
vidual fibers by rubbing t cm apart. softer vegetable matter ess. Thus the bundles of fiber are COIllpletelyreducod .and the individual fibers sep- ,arated, and allof the fibers thus obtained manicured-on coated withan envelop, of the gelatimius matter, which, by reason of its stickiness and adh rence, furnishes a means for in creasing;the l-etentiveness of the said. fibers, I, and, furthermore, increases their size, which to materially; aids in obtaining this result.
- The action of the staznpers on the peat-turf is soregulatedas only to crush the coarser particles or;. bundles of fiber which is be- :,tween the. faces of the Stampers and the table- 5- surface, while the fine particles and individuaLfibers. already segregated and which are already suitable for working into half stufi's are. protected by the thicker parts from the action ofthe Stampers, and thus remain unin- 0 jured. .By-this mechanical treatment of the peat-turfthetuseless and wasteful extraction of the weakerv and finer fibers; is sub' stan tialiy ,prevented,.and only those parts are reduced which .are;otherwise.unsuitable, while all ofthe fibers are provided with a protecting or .l'ctainin ,means which serves materially in .preventlng the fine particles from being washed away and lost :In this application .I have referred to the ,product of my .process-that is, the halls stuii'- -as being intended for use in. the manufaoture of paper or paperboard, and this is one of its prime pal uses; but it will be UI1(l(-31 stood that it may be employed to advantage .in the manufacture of various other pr'oduc ts,
, such as molded or pressed products, and 1 do not mean to limit myself to any partibular use to which the-'half stull' is to be'put.
