' SPECIFICATION forming part of Letters as n leleese, dated may 5, 1885 Application filed February 16, 1885. v (No model.)
To all whom it may concern.-
Be it known that I, FRANK X. BLACK, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Paper- Inlp Screens, of which the following is a specification.
This invention pertains to those machines used in connection with paper-making machines, and known by avariety of names, such as paperpulp screens, pulp-dressing machines, knotters, and jogs. The office of such machines is to dress the pulp by straining it and extracting the surplus water from it. These machines consist, essentially, of what may be called a vertical vibrating sieve, formed, generally, of a vat provided with a bottom with fine slit-like perforations, and fitted with mechanism to impart rapid vertical vibrations to it.
My invention relates particularly to the arrangement of parts for securing a rapid vertical vibration of adj ustable degree of the'entire straining-surface uniformly and without violent shock or noise.
My improvements will be understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a paper-pulp screen embodying my improvement; Fig. 2, an end elevation of the same; Fig. 3, an elevation of the shifting eccentric; Fig. 4, a diametrical section'of the same, and Fig. 5 an elevation of the same shown as provided with mechanism for shifting the eccentric while the machine is in motion.
In the drawings, A represents the frame of the machine; 13, the vat having the usual outlet and rigidly secured to the frame; 0, a pair of vertical yokes disposed one at each side of the machine and adapted for vertical reciprocation; D, guides secured to the frame and engaging parallel guide 7 surfaces upon the yokes, and serving to guide the reciprocating yokes into movements of true perpendicularity; E, the straining-vat provided with the usual straining-bottom and rigidly securedto the top of the yokes, being supported by such yokes and adapted to partake of their vertical reciprocations unimpeded by other supports;
F, a shaft disposed across the machine below the vat and journaled in bearings mounted in the frame; G, a pair of adjustable eccentrics secured to the shaft one at each side of the eccentrics and wrists disposed in the yokes g above the plane of the eccentrics.
The straining-vat E, with its attached yokes, reciprocates in truly vertical lines as governed by the guiding-surface of the yokes. The reciprocations are imparted to the yokes through the eccentrics and eccentric-rods, the entire weight of the straining-vat, with its contents, the yokes, and the eccentric-rods being contin uously borne by the eccentrics, the weight of the reciprocating parts serving to keep the eccentric-straps into actual contact with the eccentrics at all points in their revolution. The rise and fall of the reciprocating parts is thus produced without shock or noise; As the eccentrics are not called upon to exert a downward force upon the eccentric-rods, no lower strap upon the eccentric-rods is necessary.
In Fig. 1 I show the eccentricstraps as terminating below in lubricating-boxes swept by the lower periphery of the eccentrics. The eccentric-rods are shown as provided with screw and lock-nut devices for adjusting their lengths, thus bringing the two sides of the straining-vat to the same level. The shaft is to be provided with the usual belt-pulley or driving-gear, and, if desired, with a fiy-wheel. As
this shaft is never relieved from the downward pressure due to the parts reciprocated by it, it lies quietly in the lower portion of its boxes.
In Figs. 3 and 4. is shown enlarged one of the shifting eccentrics. The hub I is keyed to the shaft, and the eccentric G is fitted to this hub by means of a dovetail, so as to slide transversely across the shaft, the bore of the eccentric being larger than the shaft, so as to permit of this crosswise motion. The eccentrio is provided with two oppositely-disposed set-screws arranged in the plane of the cross- Wise motion, and by means of these set-screws the stroke of the eccentric may be adjusted. The reciprocation of the two sides of the straining-vat may thus be adjusted to the same degree of motion, or otherwise, if desired. Other forms of eccentric-adjusting devices may be employed such, for instance, as is illustrated in Fig. 5, in which, instead of set-screws, a.
pair of levers actuated by a sliding cone, J, serves to shift'the eccentric. Such a device serves for adjusting the eccentrics while the machine is in motion, and, if desired, the rod K,which shifts the cone J, may engage the cones of both eccentrics, and thereby provide for the simultaneous adjustment of both eccentrics While the machine is in a motion.
I claim as my invention The combination of a frame, a vat secured thereto, a shaft journalcd across the frame, a pair of adj ustable eccentrics secured upon said shaft one at each side of the machine, a pair of reciprocating yokes or equivalent verticallyguided parts disposed one at each side of the machine, vertical guides secured to the frame and engaged by the yokes, a straining-vat secured to the top of the yokes and supported solely thereby, and eccentric-rods engaging the eccentrics and wrists in the yoke, substantially as and for the purpose set forth.
