Serial No. 405031.

This invention relates to i ulp beaters, eX- tractors and cleaners and elongs particularly to unit machines for kindred purposes in the manufacture oi' paper.

An object of this invention is to construct as a unit not only a breaker beater, but also a settling trough and thickener, which will eliminate the elaborate systems such as are disclosed in certain patents of the United a@ States. In other words it is an object of thisinvention to .accomplish the same result in a single unit machine as is now ordinarily. attained by a series of individual units connected together. In some apparatus of the Els nature herein mentioned the settling troughs are one hundred to one hundred and fifty feet in length. The reason for making such troughs of that length, apparently extreme, is that when the beater is started up, say Monsa day morning, and the stock diluted to about one-half of one per cent to allow the heavy particles and materials such as sand, dirt and even paper clips and the like to settle out, the first ten feet of the settling trough collects substantially most of such foreign matter. After arun of about one day this first ten feet of the trough is completely iilled with this dirt, sludge and the like so that the stock coming into the trough simply passes over that accumulation and settles out further down the trough. By the end of the weeks runApractically no dirt is settled out in the first few feet of the trough, andy batlies are introduced at the cxtreme end of the trough to collect such unsettled4 materials.

By the construction and arrangement of parts as shown in this invention it is sought to provide an 'arrangement of battles or sand settling compartments provided with receptacles the bottom portions of which taper downwardly as set forth, andare furnished with removable bottoms of any selected tormation and operation. ltlormalls the bottoms ot the receptacles are open, ti e closures having been removed, and in this way the iirsttew sandvboxes collect usually the greater amount of refuse, which settles down through the open bottoms of the receptacles into fixe compartment below. As this heavier material 50 settles it displaces the lighter stock and water and eventually iills the compartments below the sand receptacles. When this condition of settlement is reached, the removable bottom of the receptacle or receptacles is reseated to close the open bottom, and the compartment below is then accessible for cleaning out the refuse collected in the compartment without shuttin the machine down, as the diluted stock will simply by-pass the com partment which is being cleaned out. It is a further object of this invention to equip each compartment with an easily removed or opened and closed watertight door, so that the operation of cleaning out the compartment may be accomplished as quickly `as practicable. Only one of the compartments need be cut out of service at any one time. It is intended that if necessary this cleaning procedure may be undertaken once or twice a day, and in this manner the undesirable eX- treme length of the settling trough can be obviated successfully.

It is also an object of this invention to combine as herein shown and described a long wire net covered cylinder mould similar to standard wet machine types for thickening the dilute stock, all off which can be built into the single unit machine; A pump is shown in this application and adapted tor drawing oli the wat-er trom the inside of the cylinder mould and returning the so-called white water back to the mixing chamber or into the beater tub where desired. The thickened stock leaves the mould by way' of a couch roll from which it is scraped oil and dis. charged to a chest or to other reiining equipment the same as is the common practice with wet machines.

The special construction and arrangement of the various parts of the unit machine comprising this invention are illustrated in the accompanying"drawings, of which Fig. l represents a side View partly in vertical section, and showing all parts assembled. Fig. 2 is a. vertical cross section of one of the settling compartments. and the tapering receptacle therein showing the removable bottom ot the receptacle, and the hook rod ordinarily cmployed to take the bottom out and to replace it. Fig. 3 is a vertical cross section of part of the mixing chamber showing the vertically extending director plate which is located in proximity to the beater roll, and illustrating also the gears, gear shaft and handwheel for moving the adjustable gate or slidel of the director plate. Fig. 4 is a top view of the parts set out in Fig. 1. Fig. 5 is a fragmentary vertical and longitudinal section transversely of the beater roll shaft, showing perforations in the 'up curve of the director plate, and setting out likewise a per'- orated beater plate beneath the beater roll covering a chamber opening into the mixing chamber. Fig. 6 is a fragmentary top view showing a screen arranged at the curve of the inner wall of the tub. Fig. 7 is a fragmentary vertical section to show the breaker roll provided with an extractor hood to receive pulprthrown off by the breaker roll of suiiicient ineness to pass the perforations. In Fig. 7 also is shown the slice partition exhibiting the openings or recesses therein and theplates for, controlling the extent of the open recesses in practice. In Fig. 7 is set t'orth also a representation of the pipe for conducting material Jfrom the -breaker roll extractor hood into the tub near the beater roll. Fig. 8 is a top view-of the parts shown.

in Fig. 7, Withthe hood extractor chamber shown in section. The pipe for conducting the fluent material from the extractor hood to the tub next to the beater roll is also illustrated inFig. 8. Fig. 9 is an end portion of the movable part of the slice partition, and sets out the adjustable plates which are used to control the size of the recesses in the plates, and the clamps-for securing the plates are indicated. Fig. 10 is a side view partly sectional showing a bladed auxiliary roll to take beaten stock From the beater roll.

Throughout the'drawings and description the same number is used to refer to the same part.

Considering the drawings, upon a suitable base 1 the tub 2 is erected and provided with a midfeather 3 of any chosen form and extent. A roll shaft 4 carries a beater roll 5 and a breaker roll 6, the beater roll being of larger diameter than the breaker roll. Ordinarily a. hood 7 coversl the rolls, and the rolls are combined in one as set forth. ,The breaker roll may be of standard construction with approximately twenty flybars, whereas the beater roll would be ot larger diameter with a greater number of bars spaced closer together,since it is not necessary to produce circulation by the beater roll. In proximity to the beater roll is an upwardly curving and extending plate, termed for the purposes o'f this description a director plate, since it directs the beaten stock upwardly to the opening 10 controlled by the sliding gate 11 actuated by suitable racks and gears l2 on cross shaft 13. revolved by handwhccl 14, as best shown in Fig. 8. The construction and of this arrangement is in practicetoholdback a considerable quantity Iot" the stock in the beater roll chamber by means of the adjustable opening marked 10, and only permit enough stock to pass into the mixing chamber 4 adjoining t-he plate 9 as would be required for the setproduction from the machine. The rest'of the stock would continue over the roll and under the roll upon the bed plate tor further treatment. As shown in Figs. 1 and 5 a doctor 15 directs the material thrown olf by the beater roll through the opening 10. It is believed to be within the purview of this invention to use any construction o t doctor device.

As delineated in Figs. 1, 4, 7 and 8 this invention includes a slice partition made up of a lower and fixed part 16, and an upper part 17 movable with respect tothe lower part, by means of the adjusting screws 18 and handwheel nuts 19 supported by the cross bars 20. As best illustrated 'in Figs. 7 and 9, the upper and movable part 17 of the slice partition has a number of openings 21, and the sizes of the openings are governed by the sliding plates 22 secured byl clamps or screw buttons 23. This invention is in no sense limited to the plates and the clamps for adjusting the open area of any recess 21, as those devices are susceptible of various modification.

In Figs. 4 and-8 is shown an ordinary backfall in proximity to the breaker roll 6.

Considering Figs. 1 and 4 there will be noted next rthe upwardly extending plate 9 a mixing chamber 25, into which the material from the beater roll is directly diverted, and

, the side of the chamber 25 oppositev the plate 9 is constituted by the vertical battle plate 26, of which there are a succession as set forth. The tops of the ballle plates 2G are below the top edge of the tub, and Jfrom the top of the tub walls intermediate baille plates 27 extend downwardly. The baile plates 26 and the outer wall ot' the tub with i s inner wall 2 comprise a series of compartments of which any number may be provided. In each compartment is a refuse receptacle 28 the sides of which taper downwardly, and each receptacle has an open bottom which may he closed-bya removable bottom plate 29, as best illustrated in Fig. 2, and the closure 29 is usually manipulated by means ot' a vhook rod 30-which is engaged and disengaged assenso i 3 is a couch or take-oli roll 39 adapted to take the thickened stock off the screen roll 38. The roll 39 is scraped by the doctor blade 40, and the thickened and cleaned stock is deposit-edfin the final chamber 41 shown in F ig. 4, from which dchemiberby way of the outlet pipe 42 the stock may be conducted to a chestor further refining machinery not shown. Towash olf the screen roll 38 externally, the spray head 43 of any desired construction and arrangement is introduced as shown in. Fig. 1. lt will be noted further in Fig. 1 that a connection 44 is in communication with the interior of the screen roll 38, and by Way of connection 44 the rotary pump 45 takes the water from the interior of the roll and forces the same past valve/46.

through the elevated pipe 47 into the mixing chamber 25, or elsewhere into the tub as may be desired. bviously, the flow of returned water in pipe 47 may bedivided and delivered at any points found to be advantageous inl a,l given operation.

lt is further believed to be within the scope of this invention to replace the relatively wide bed plate 8 set forth in Fig. 1 by a perforated bedy plate 49 adapted to pass beaten stock downwardly into la receiving box 50, which is in open communication with the mixing chamber 25. It is believed to be equally the right of this applicant to provide the inner wall 2 of the tub at the turn of the wall as shown in Fig. 6, with a screen 51 for the passage of stock suitably beaten. The curving and up-turning portion of the director plate 9 nea-r the roll 5 may be provided ivith a perforated portion 48 for passing beaten stock into the mixing chamber 25. Such additions are held by lthis applicant to be minor details, asl they are devices of well known structure and their operation and use is common knowledge in the industry to which this invention is designed to be applied. y

Considering Fig. 7 there will be noted adjacent to the beater roll 5 an adjustable doctor blade 52, which can be changed in position either to the right or left or up or down as mai-*be chosen. There may be also applied to he breaker roll 6 as set forth, an extractor' hood having a perforated face plate 54, and an internal spray pipev 55 to clean the perforated plate by Water spray. From the lower part ot the hood 53, pipe 5G conducts the fluent matter into the space between the slice partition 16 and the beater roll as set o ut also in Fig. 8.'

Considering Fig. 10, there will be noted in the place of the doctor blade, an auxiliary roll '57 on across shaft 58 whereby it may be rotated by means not shown but of any common elements, near the beater roll 5 and in like direction. The blades 59 of the auxiliary roll in passing near the blades of the beater roll take the material from the beater roll and throw the same against and through the curved screen 60 swept by blades 59 of the auxiliary roll and the screen is kept clear by the movement of those blades. Such portions of the material not passed through the screen 6 0 are carried by the beater roll over the top thereof and under the hood 7 to be again passed under the beater roll. It will be observed in Fig. 1 0 that the curved screen 6() is removably secured to the director plate 9 by the bolts 61., Any desired changing of the screen may thus be made.

In the operation of this invention, the stock beaten by the beater roll passes into the mixing chamber and into one after the other of the settling compartments described. The refuse materials are deposited in those compartments as previously explained, and they are cleaned out one at a time if need be and without interfering with the continuous running of the apparatus tor any length ot time.

The cleaned and thickened stock is taken out at the end of the series of settling compartments, and the Water therefrom returned to the mixing chamber or tub. 1

The heavier materials are broken up by the breaker roll, and the lighter portions in circulation pass between the slice partitions 16 and 17, or over the latter and through the diii'erent recesses 21 adjusted as required for a .given operation.
