BEATER-ENGINE ROLL.
Application filed November 1, 192?. Serial No. 280,281.
lhis invention relates to beating engines for macerating paper stock and has special reference to the beater bar or knife, the object being to provide a beater bar by the use of which a more complete circulation and disintegration of the stock than has heretofore been possible will be attained. The invention is illustrated in the accomanying drawing and will be hereinafter ully described, the novel features being particularly pointed out in the appended claims. In the drawing, Figure 1 is a plan view of a beater roll having the present invention embodied therein;
Figure 2 is an end view-of a portion of the roll;
Figure 3 is a view showing two of the bars in elevation.
lhe beater roll is mounted in the tank or tub in the usual or any approved manner and consists of disks, one of which is indicated at 1, secured upon a central shaft 2, beater ,bars or knives 3 extending parallel with the shaft arid held to the disks by end 2 rings 4, and wedge blocks 5 driven between adjacent knives or bars to maintain them in fixed spaced relation. Generally the bars or knives 3 have their inner edges seated in recesses provided therefor in the edges of the several disks, and the end rings engage in notches 6 in the ends of the knives so that when the several parts are assembled the knives will be very firmly secured. In the outer edge of each knife' orbar, spaced notches or recesses 7 are formed and the bars are arranged so that the notches in adjacent bars are staggered, each notch in each bar being alined circumferentially of the roll witha lug or tooth 8 between two notches in 40 the adjacent bars. It will be noted, more particularly upon reference to Figure 3, that the opposite outer. corners of alternate bars are cutaway, as at -9, on lines corresponding to the contours of the notches 7 so that the staggered notch structure is car- HEISSUED ried to the extreme ends of the beater roll.
The beater roll is rotated in the tank in the usual manner to cause the bars to'successively impinge upon and work through the stock. The notches in the working edges of the bars act upon the stock so as to quickly disintegrate the same, the stock being torn or shredded and the tendency of the same to wrap around the roll being overcome. The bar embodying this invention creates a greatly increased suction through the stock so that'the latter circulates more rapidly and etliciently than with the devices now in use and the work is completed in less time and with less power than has heretofore been necessary.
While, for illustrative purposes, the invention has been shown embodied in singly spaced bars, the bars may be arranged in clusters, and it will be understood that the dimensions of the notches may be varied according to the characteristics of the stock to be treated. In practice, a plurality of interchangeable sets of bars will be provided so that, before starting work, the operator may apply to the, roll the bars best adapted to the particular stock which is to be treated.
Having' fully described my invention what I claim as new and desire to secure by Letters-Patent, is
1. A beater roll having circumferentially spaced beater knives provided with spaced notches in their working edges, the notches in adjacent knives being relatively staggered.
2. A beater roll having circumferentially spaced beater knives, the opposite outer corners of alternate knives being cut away and the knives having spaced notches in their working edges, the notches in adjacent knives being relatively staggered.
In testimony whereof, I have signed this specification.
ARTHUR M. MolEHILLIPS.
