UNITED STATES EDWARD BENTON FRITZ, OF CHICAGO, ILLINOIS.

HYDRATING BEATING AND REFINING MACHINE.

Application filed November'20, 1924. Serial No. 751,051.

To all whom it may concern:

Be it known that I, iEDKVARD BENTON FR'IT'z, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a newv and useful Improvement in Hydrating Beating and Refining Machines, of which the following is a specification.

This invention relates to a class of machines which are adapted to reducing paper, rags, pulpand such other material as is used in paper making to a consistency and relation fitted'to prosecute the manufacture of paper or paper stock.' My objects are several, as will be shown by the description and claims; but my primary objects are economy-of space, economy of operation, economy of construction, economy of power, economy of time, maximum beating surface and gravity process.

In the paper making industry, in the preparation of the material for paper, there are several very important processes carried on,'the central workbeing carried on in what is commonly known to the art as a beater,. which almost universally consists of some form of a vat or receptacle in which the material is moved around in a course practically horizontal, and which said material in the course of its travel is made to pass through a constricted aperture at the point ,of which aperture a revolving rotor is horizontally functioned causing the mass to slowly passthrough the aperture and in,

passing to come into contact withbeating or brushing surfaces. In this process the mass moved and operated uponbeing more than 90% water-1s heavy, a .dead weight to lift and move, and the process is necessarily relatively slow-inyolving a large expenditure of power: the elements of impact, friction, resistance, and lift are practically at a maxi- "mum. In; most cases separate devices are usedto hydrate and primarily destroy the identity of the material before it enters the beater; and other devices are used to do the refining after it has been beaten in the beater. It is also well known to the-art that the devices referred to require a large .base area to accommodate them. In the device herein disclosed the whole process of hydrating, beating, and refining islaecomplished ready for the papermak ng' machine.

In applicants device-the base area is very small in comparison, the materiah in lts processmoves almost wholly by gravlty and Patent Number 1,528,201, and is based upon the fundamental principles in that application.

The accompanying drawings illustrate one form of my invention:

Fig. 1 is an elevation, with parts broken and cut away to show internal relations.

Fig. 2 is an opposite elevation practically through the center of Figure 1..

s Fig. 3 is a view of a rotor adjustment. d Fig. 4' is a perspective on edge ofa rotor isc.

Fig. 5 is an enlarged and somewhat exaggerated section of a rotor disc.

Fig. 6 is an inside edge view of a stationary disc, with a lower portion cross sectioned. 1

Fig. 7 is a diagrammatic view of the position and relation of th rotors and the discs.

As shown the mechanism. consists of four major parts viz: a primary disintegrating tank 10; a reservoir 11; a housing 14 containing heaters 19, beating rotors 20 and associated parts; and reservoir 13 with associated pump 25. 10 is a tank receptacle into which is delivered water and the mate- .voir 11 I provide one or more agitators 16 on shafts adapted to keep the mass from settling; leading from the reservoir 11 I provide a conduit 18 having an elongated opening or mouth wherethrough to discharge its contents into the upper chamber 12; I provide a housing 14 having therein a plurality of chambers 12 superimposed one upon the other and having similarly elongated openings 29 in each chamber communicating with the one adjacent; these chambers 12 extend horizontally and are circular. In each of said chambers 12 a power driven rotor 21 is functionally jour n aled. These rotors may be synchronized, but I preferably. so associate these rotors that they willtravel at different speeds. Be-

tween tank 10 and reservoir 11, and betweenreservoir 11 and upper chamber 12 I provide means of

communication

18 and 28,

with gates or yalves 27, for regulating the flow the entry into upper chamber 12 being an elongated mouth, the lowest of these chambers 12 has an openingto discharge its contents into a receptacle 13.

rotors consist of a shaft 21 and preferably assembled thereon a multiplicity of circular discs 20 having raised portions 23 thereon; these raised portions 23 on the discs 20 are designed tangentially for several purposes,

primarily they play the part of paddles in an overshot wheel and tend to assist in driv-- ing the rotors by the weight of the material falling thereon, and secondarily they tend to throw the material outwardly against the surfaces 22 on the discs 19; in this action the material is swished and brushed back ward and forward to accomplish a more perfect reducing of the same. The discs 20 are assembled alternating with the semidiscs 19 as shown in Fig. 7 I preferably make these surfaces withcorrugations, but they may be plain surfaces without departing from the principle 'set forth. The rotors are relatively thick at the centers and taper outwardly to their edges to function in conjunction with the opposite tapering'ofthe discs '19. I provide an adjusting means 24 in connection with the bearings of each of the rotors assembled on the shafts 21 whereby to accommodate the various grades of material and effect various degrees of refinement. The relation of the travel of the material and the direction of the rotors is indicated by arrows. In the drawings I show three rotors in a like number of chambers, but the number may be ultiplied without in any way departing f m the principle, the basic idea being the refinement of paper stock through a unitary process of superimposed chambers discharging one into the other whereby gravity plays the part of eliminating the raising or handling of process. I provide a pump 25 with an outlet '26 associated with the receptacle 13 for emptying the same or it may be used as shown to pump the material back into the reservoir 11 if it be desired to repeat the process, but this pump and its connections have no special limitation upon the applicants device. The

conduits

28 and 18 areof no specific form except as channels of communication between the designated parts. In the bottom of the tank 10 and the reservoir 11 I provide respectively raised portions at the discharge openings to prepassing into the tat'ors therein for the purpose of maintaining the consistency of the material on its course from the tanks 10 to the chambers 12. The material entering the u'pper chamber 12 falling upon the rotors is by these thrown outwardly against the surfaceof the discs which in turn tends to throwthe material back toward the center and "downward, in the process the fibers being brushed, hydrated and refined. The repetition of the process in adjacent lower chambers reduces it to the consistency desired. By having the speed of each lower rotor slightly increased over its next higher rotor accomplishes the taking of a mass from the rotor' above faster than a normal delivery. This device fully utilizes the economical a plication of gravityto the handling and re ning of paper stock; economizes power; increases producti0n; provides continuous operation, and secures progressive refinement. I

It will be evident that the principles here shown are subject-to various embodiments, and I am limited only by the scope of my claims.
