Specification forming part of Letters Patent No. 124,196, dated March 5,1872.
SrizorrrcATIoN.
' l, GUs'rM/'E DEMAILLY, of Argenteuil, in the Empire ot' France, have. invented certain improvements in the mode ot' extracting the filaments ot' straw and the bark of the mulberry-tree, and converting the same into pulp for the manufacture ot' paper, ot' which the following is a spccilicatioiu' Nature and Objects ofthe Invention.
y to remove the coloring mat-ter produced by the etl'ect ofv the caustic lyc. In prelnlring the bark of the mulberry-tree, a simple water retting will snllice when the tree is not green 5 or, it'it is desired to accelerate the work, itmay be cut in lengths otl from eight to ten centimeters and boiled for a quarter of an hour in a soda--lye at one-halfa degree, when it may be withdrawn and passed to the machine for converting it into pulp.
Dscription ofthe Drawing.
Figure 1 is a vertical section of thc appa-- ratus employed. Fi g. 2 is a sectional end view ofthe same.
A is a groovcd cylinder, turning round its axis o, and `moves in a trough, B, formed of plates, also grooved, and whose circumference does not exceed thatot' the cylinder by lnorc than three centimeters, and leaving between them a space determined by the nature ot' the substance to bc treated, and the state to which it is to hc reduced. These plates arc maintained against the cylinder A by means' ot' india, rubbers (l, lxed by one ot' their extremities to al transverse shal't, u, l'urnished at its ends with pivots, receiving rollers, rolling on an inclined plane, p.- 'lhcse lndia rubbers embrace the whole ot' thc plates, and wind on a second transverse shaft,a, also rolling on an inclined plane, p', and are fixed by means circular crowns ot' sheet-iron, I), pierced with as many rectangular guides as there are plates.
These guides impart to the plates B a percussion motion, and prevent them rising one on the other. A space, which may vary from one to tive-tenths ot' a, millimeter, is made between the plates B and the cylinder A, according as it is desired to make paper-pulp, or simply to extract the filaments.
TENT OFFICE.
The
Having thus described tho parts ot the maA chine, I will now explain the modus operandi. The matter, having undergone the chemical process before mentioned, is spread on the endless cloth T, which leads it between the grooved cylinders M M, which latter distribute it uniformly to the machine, and force it t0 pass through the entrance r; -it is then drawn along by the grooved cylinder A, and reaches the tirst plate, which, yielding to the pressure, strikes the matter, which, continuing to arrive, is treated similarly by each blade in succession. From this it will be observed that the drawing movement ot'thc cylinder A,in conjunction with the striking of the plates, causes the separa-tion ofthe filaments uml the gunnny particles, destroys Ithe parcnchyma, which escapes through the interstices of' the grooved plates B, and effects a partial solution ot' the grim in the' water contained in the basin b. The matter leaves the machine by the opening N in the form otl filamentous rolls, and, falling on thc endless cloth T', is thence conducted to an agitator, where it isseparated, and is then ina condition to bc employed either in the formation ot' tissue, (in t-he case of the mulberry-l-mrk,) or t'or conversion into paper-pulp. ln reducing the straw aty once into pulp, the cylinderiscompletelysurrounded with grooved plates; in thiseasc thestraw f'alls through the interstices ot' thc plates intothc lower basin l), whence it has a continuous or intermittent flow. As regards the bark, 'at'ter having subments, itis subjected to a Claim. I claim as my invention- The rotary grooved cylinder with groovcd blades, the India rubbers for the distribution ot' pressure, the iron cheeks and guides to the groovedplates, and the chemical process for preparing the 'filaments before. submitting them to the machine, substantially as and for the purposes herein set forth.
