IBEATING AND REFINING ENGINE.
' Application filed June 3,
To (412 whom z't'may concern 7 Be it known that I, THOMAS HENRY NASH, a subject of the King of Great Britain and Ireland, and residing at Garland Hill, St. Pauls Gray, in the county of Kent, England,
I have invented certain new and useful Imgiving a continuous flow at the outlet.
l-Ieretofore, with certain types of hollanders or beating engines, a roll is placed at one side of a deflecting plate. It has been observed that provided the stuff is entered at a point close to the said plate, its
path through the beater is that of a more or less well defined stream, gradually progress- :ing toward the outermost part of the roll.
in the present invention advantage is taken of this tendency to formstreams, inasmuch as the entry of the stuff to the beating engine is regulated for this passage under and reen ry to the roll so that a defined number of passages under the roll is assured over the width of the roll. 7 By multiplying the number of rolls a definite number of beatings can" be arranged to take place. Apart from the added etficiency which such a construction provides, any such'system gives advantage in treating different types of pulp according to the required amount of treatment peculiar to each class of stuff treated.
Now, according to the present invention, hereafter more particularly described, the rolls are arranged in multiple succession within a common trough andso arranged that the stuff is fed forward by the said rolls in a gradual upward path, allowing it after passing under the furthermost roll to be returned automatically by gravity in defined streams to the first of the series for re-treatment.
The invention also comprises an arrangement for increasing or decreasing at will the width of the stream of stuff issuing from the feed plate in order to increase or decrease the number of times the stuff is to Specification of Letters Patent.

1919. Serial No. 301,420.
pass under the rollers as more fully explain-ed hereinafter.
Bythe use of the invention a large saving in power and time is effected and the stuff more eiiiciently beaten by not mixing stuff that has partly or fully been beaten with stuff which has not passed under the rolls.
'The invention will now be described with reference to the accompanying drawings in which Figure l is a sectional elevation of a beating engine constructed according to the invention and Fig. is a plan of Fig. 1.
r In the drawings, 1 indicates two containers of usual form for mixing the stuff or pulp. which is fed by gravity down. a
pipe 2 opening into an inclined feed plate 3 of the beating engine, the containers being so arranged as tQgIVG' a constant feed. The
beater comprises sides l and bottom 5 of concrete, the sides carrying adjustable bearings 6 for the spindles 7 of a number or beater rolls 8, four being illustrated but this number may be increasedor decreased ac cording to the output which it is desired the engine'shouldhave. Each spindle also carries a driving pulley 13. I
The bottom 5 of the engine is stepped and the rolls 8 are also disposed in upwardly stepped relationship to one another so that a suflicient head ofstuff will be maintained to return the stuff after each passage through the rolls; The stuff passes toward the openings 10, 10 10 of a number of 'returripipes 11 passing beneath the bottom 5 and delivering the stuff throughopenings 12, 12, 12 onto the feed plate 3. An outlet: pipe 14 conveysthe beaten stuff to the usual stuff chest of a paper making machine.
The feed plate'3 is provided with a number of' defiectors' 15, one being provided he tween each opening 12 and one for the pipe 2. These deflectors comprise a number of flat plates hinged at 16' and'operated by a rod 17 connecting all the deflectors and provided with an operating handle 18. A sluice or gate can be used to obtain the same result.
In the operation of the invention stuff or 011 to the feed plate through the opening 1%, this operation beingrepeated automatically so that with the particular arrangement illustrated the stuff returns five times beneath each roll and finally passes away through the pipe 1 If it is desired to pass the stuff under the rolls a greater number of times, the deflectors 15 can be moved for example to the position indicated in dotted lines in Fig. 2 thereby narrowing the stream of stuff which passes from the feed plate to the rolls. At the same time the inlet valve should be partly closedto give the necessary width of flow of material.
' As soon as the stufi commences to pass away through the outlet 14:, the whole bottom 5 of the engine will be covered by a mass of stuff moving toward the left, the whole consisting of a number of streams each of which has passed through the rolls a predetermined. number of times.
In this manner the whole of the stuff is very thoroughly beaten and its quality will be uniform throughout as no part of the stuff receives any more or less treatment than any other part.
The bearings6 of the rolls 8 may in practice be arranged in vertical adjustment so that any of the rolls may be raised to inoperative position in accordance with the requirements of various materials under treatment. I
I claim 1. A continuous beating and refining engine for pulp, stuff and the like, for use in the manufacture of paper including aseries of beating rolls, means for causing said stuff to pass through said rolls, and means for causing said stuff to be returned and refed through said rolls at a different point along the width of the bed of the engine any predetermined number of times.
2. A continuous beating and refining engine for pulp, stuff and the like for use in the manufacture of paper including a series of beating rolls mounted in upwardly stepped relationship, an upwardly stepped bed, a feed plate, means for returning stufl to the feed plate after each passage through said rolls and means for varying the width of the stream of stuff passing from said feed plate in accordance with the number of times the stuff is to pass through said rolls.
3. A continuous beating and refining engine for pulp, stuff and the like for use in the manufacture of paper, including a series of beating rolls mounted in upwardly stepped relationship, an upwardly stepped bed, a feed plate, means for returning stuff to said feed plate after each passage through said rolls, a plurality of openings in said feed plate and an adjustable deflector adjacent each of said openings for varying the width of the stream of stuff passing from said feed plate in accordance with the number of times the stuff is to pass through said rolls.
4. A continuous beating and refining engine for pulp, stufl and the like for use in the manufacture of paper, including a series of beating rolls mounted in upwardly stepped relationship, an upwardly stepped bed, a feed plate, a plurality of pipes disposed beneath said bed, means whereby the stuff after each passage through said rolls is caused to return through said pipes, a plurality of openings in said feed plate c011- nected to said pipes and an adjustable deflector adjacent each of said openings for varying the width of the stream of stuff passing from said feed plate in accordance with the number of times the stuff is to pass through said rolls.
5. A continuous beating and refining engine for pulp, stuff and the like for use in the manufacture of paper, including a series of beating rolls mounted in upwardly stepped relationship, an upwardly stepped bed, a feed plate, a plurality of pipes disposed beneath said bed, means whereby the stuff after each passage through said rolls is caused to return through said pipes, a plurality of openings in said feed plate connected to said pipes'and means for varying the width of the streams of stuff issuing from said openings in accordance with the number of times the stufi is to pass through said rolls.
6. A continuous beating and refining engine for pulp, stuff and the like for use in the manufacture of paper, including a series of beatingrolls, means for supporting said rolls in the sides of said engine, a feed plate, pipes passing beneath said bed to return stuff to openingsin said feed plate after each passage through said rolls and means for varying the width of the stream of stuff issuing through said openings in accordance with the number of times the stuff is to pass, through said rolls.
7. A continuous beating and refining engine for pulp, stuff and the like for use in the manufacture of paper, including a series of beating rolls, means for causing stuff to pass any predetermined number of times through said'rolls and means for varying the width of the stream of stuff in accordance with the number of times the stuff is to pass through said rolls.
In testimony whereof I afliX my signature in presence of two witnesses.
