' To all whom it may concern Be it known that l, WILLIAM H. Sronrn, of Water-ville, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Apparatus for Disintegrating Fibrous Material; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and y invention relates to an improvement in apparatus for disintegrating fibrous material used in the manufacture of paper pulp, the object being to provide a target against which the stock is forcibly project ed, with a plurality of surfaces of different milling capacity, the target being adjustable whereby any one of said surfaces may be readily moved to a position to receive the discharge from a stock projecting nozzle.
With this object in view my invention parts and in the details of construction as will be more fully described and pointed out in the claims.
The accompanying drawing is a view in elevation of my improved target, alsoshowing the nozzles through which the stock is projected against the target. Paper stock intended for very thin paper must be treated difierently from that intended for heavy paper. It is also desirable to change the targets, where a change in the grade of ma terial is necessary, and again it may be desirable in order to shorten the process, to work the stock against one surface, say a plate having sharp pyramidal projections which'will quickly separate and divide the ers, and conclude the operation with a plate having a less roughened surface, as for instance sandstone or carborundum.
My present invention provides a target having a series of surfaces of different milling or disintegrating capacity, and it consists of a disk 1 provided with a peripheral flange 2, the disk being centrally secured to a shaft 3, by which it may be turned to present any one of the several disintegrating surfaces 4:, 5, 6 7, 8 and 9 to the pulp or stock streams which are forcibly ejected from the nozzles 10.
The disk 1, in the present instance carries the cutting blocks or surfaces, on one of its faces only, but it may have them on both faces in which event a second set of nozzles would be located to project the opposite face. Again horizontal with the nozzle same, or vertical with the nozzles at the side. The nozzles 10 are located at an inclination to the working face of the disk so that the stock will be projected tangentially against the milling surfaces of the several working sections of the disk.
7 be composed The Working sections ma of basalt or lava stone, one of carborundum; one of sandstone and several of metal or stone having serrated faces. In one, the serrations or ridges are shown extending in straight lines transversely across the section, in another the serrations are curved and in another the face of the plate is made up of a series of small pyramids. lf stone or composition sections such as sand stone,
the stock against the disk may be above or below basalt or carborundum be used, the surfaces may be either grooved or serrated, or left in their natural rough condition. The material used for the working section and the method employed for producing the roughened or serrated faces is unimportant, as the principal object is to provide the disk with-a series of working surfaces so as to provide for varying cutting or disintegrat ing capacity.
y first projecting the stock against a serrated plate the stock will be quickly disintegrated and by finishing up with a sandstone, lava or carborundum surface the stock will be more finely divided and the fibers as perfectly separated as they can be in the ordinary beater engines and in much less time and at but a fraction of the cost.
The nozzles 10 are connected to pipes leading to a pump which draws the stock from a vat in which the target is located. The nozzles are so located with relation to the disk that the stock will be projected against the roughened surfaces tangentially and then fall back into the tank, and is kept circulating through the tank, pump, and pipes against the target until it has been reduced to the desired degree of fineness. This contact of the stock with the roughened surfaces separates or pulls the fibers apart without seriously impairing the strength or reducing the length of the original fibers.
Instead of circulating or repassing the stogk through the vat, pump and nozzles until it has been reduced to the desired degree of fineness, it may after one contact with the target he passed on to a reducing llti engine or other apparatus employed in the paper making process.
The action of the roughened faces on the stock is to divide or separate the fibers without shortening them and this is What is meant by the term milling used in the specification and claims and actual use of the apparatus has proved beyond question, that stock can be prepared, by this apparatus for the paper making machines without any treatment whatsoever in the old style of beaters.
Having I claim as new and desire to secure by ters-Patent, is 1 1. In apparatus for disintegrating fibrous paper stock, the combination of a nozzle for discharging the stock, a target against which the stock is projected, the said target having a series of working sections on the same side thereof and of dilferent milling capacity, and means whereby the stock may be ischarged against any one of said sections.
2. In apparatus for disintegrating or dividing fibrous paper stock, a target against which the stock is projected, having a plurality of working sections on the same side thereof, the said sections being of different milling capacity, and the target being adjustableso as to bring any one of said sections into the plane of the ejected stock.
fully described my invention what Let- disintegrating or dividing fibrous paper stock, the combination of a nozzle through which the stock is ejected, and a movable target located to receive the discharge from the nozzle, the said target having a series of working surfaces of dilferent milling capacity.
4:. In apparatus for disintegratingand dividing fibrous paper stock, the combination of a nozzle through which the stock is ejected, and a disk mounted to rotate and provided with a plurality of Working surfaces of difierent milling capacity, any one of which may be brought into line With the nozzle to receive the discharge therefrom.
5. In apparatus for disintegrating and dividing fibrous paper stock, the combination of a nozzle through which the stock is ejected, and a disk centrally mounted to revolve, the said disk being provided with a plurality of surfaces arranged in a circle around the axis of the disk, the said surfaces 3. In apparatus for being of difierent material and of different milling capacity.
