The present-invention relates to paperpul heaters, such asare employed in pape'r mal i ingmills; and its oh-jec't is, gener'ally,to provide an improved machine of that character; and more particularly, to provide an improved construction and combination of parts in such a machine ;-and'fu-rther, toprovide such a constructionwherein plastic or concretebottoms are combined with vertical in walls of metal or wood in formingthe-circuitous pulp-channel of the machine; and further,.to provide such a channel-in which the radii of the turns thereof are increased and the cross-sectional. dimensions of successiveportionsof such channel are so correlated witheach otherIand with the verticalinclination of their bottoms thateconomy of space is efiected and the fi0w..:ofthepaper pulp through said channel is made uniform; and further, to thus" construct said channel and its successive portions and turns that lodgment of'the paper pulp therein is eliminated or minimized. 7
These and any other andmore specific objects hereinafter appearing are attainedby,
and the invention finds preferable. embodiment in, the structure hereinafterparticularly describedrvin ,thebodyof this specification and illustrated by Itheaccompanying drawings, in which: c a
Figure l is a top plan view of a paper-pulp beater; r Figure 2 is a side elevational viewthereof; Figure 3 is a transverse.sectionaliview of the same taken on a vertical plane corre-' sponding to line 3-3 of F iguresl and 2;
Figure 4 is a transverse sectionalfview of the sametaken on a vertical plane corresponding to line 44: of Figures J1 and V2; to Figure 5 is a longitudinal sectional view of a portion of said machine taken on 'a-vertical plane corresponding to" line ;5 5 of Figure 1 and i Fi gureG is a longitudinal sectional view of a portion of the same taken on a vertical plane corresponding to line 6- 6 ofF-igure 1. In these drawings abeating machine of the Horne type, such as is employed in paper making mills is shown, comprising a circuit- 5 ous channel designated generally 1, and at one endof the machine a rotatable beater roll 2 of common form having a shaft 8', which roll extends downwardly into the channel and, coop eratingwith the member or bed plate 4 in the bottom of the channel, servesto break up the paper pulpinto small portions andas sists in the maceration thereof, and also causes the macerated pulp to flow along the channel in the direction of the arrowsshown therein,'by ra'ising the pulp over the top of Q the roll from the lower portion 5 of the channel to and into thehigher upper end of portion 6 of the channel whose bottom-7" inclines downwardly toward said portion 5 adjacent the turn 8 of the channel. The pulp mass is thus given a circuitous movement through the channel. The bearings 9 in which the rolls shaft 3 turns may be raised or loweredrelativelyto the'member 4 by well known means indicated in the drawings and for purposes well understood in the art. a
In machines of this character considerable difficulty is encountered inmovin'gthe entire mass of pulpthrough the channel, owing to a tendency of portions ofthe pulp to lodge along the sides of the channel particularly. at turns thereof. This difficulty arises from the fact that in such machines generally, changes in direction offlow are efiecte'd by angular deviations in the channels since-the 3 walls of the channels are inthe main flat'sur faces with intervening angles rather than non-angular curved surfaces which wouldinsure easierand more gradualchanges in path of flow; and also from the fact that the cross- 5 sectional dimensions of certain po-rtionsof the channel are not sowellrelated to such dimensions ofother portions; and also to the fact that the vertical inclination; of the bot tomsof such portions are not properly correlated. W 1 i V i To properly correlate the' cross-sectional dimensions of the various portions of the channel and the vertical inclination of their bottoms'is therefore one of the principal objects of this invention. Y It will be understood thatthe pulp mass having beenraised by theroll2 overthe top thereof to enter the upper endof channel portion 6, the mass will flow along said portion (whose bottom 7 is considerably inclined downwardly) more rapidly than the .mass
will flow along the channel portion 5 (when tion 6 maybe considerably lessjthan' that of portion 5, and yet an equal amount of pulp will pass through each of the channels said portions in the same lengthof time." It will also be understood that by dividing the entire width of the machineinto suchtwoportions 5 and 6 of properly related width, the horizontal space occupied by the entire machine may be economized. ,'.It is therefore an important feature of this invention that, ina' beating machine of giveniwidth,the mid: feather or. partition 11 between-portion 6 (whose bottom 7 has the greater vertical inclination) and portion 5 (whose bottom 10 is relatively of less vertical inclination) is so located that said portion 6 vis narrower than said portion 5, as well shown in Figure 1.
Moreover, by thus locating the mid-feather nearer to thevertical wall 12 of the machine and farther from its opposite vertical wall 18, the portion 5 of the channel adjacent the r0- tatable roll 2 is-made more nearly straight than it could be if the mid-feather 11 were locatednearerthe wall 13 of the machine. This is apparent in Figure 1, where the channels turn 14 (through which the pulp passes from channel portion 5 to the rotatable roll 2) is at one side defined by curve 15 in the vertical wall 16 (a continuation of the mid feather), such curve being not so abrupt (or of such short radius) aswould be necessary if the mid-feather were nearer the wall 13 of themachine and the channel portion 5 therefore narrower. I c In formingthe pulp channel of this machine, plastic (concrete) parts are advantageously combined with metallic or wooden parts. As particularly well shown in, the cross-sectional views (Figures 3,. 4, 5 and 6) thebottom of the channel, except for that cross part 17 of portion Gthroug-h which'part] the pulp (after being raised by the rotatable roll 2) passes, is made of plastic'material cement and the forms between which it is poured are the vertical walls of the machine,
including the mid-feather or partition wall 11.. These walls may be wooden or metallic plates as shown. Thus,-in making the body of this machine (i. 'e. the pulp channelfthereof) it is only'necessary to frame the vertical walls (as the metallic plates shown) and pour the concrete-between them, shaping the bottoms of the channel portions to the proper inclination, and desirably forming curved corners at their sides as illustrated. However,
these vertical walls of the channel may, of
course, be; made .of concrete aswell as the.-
b t m 0nd portion and having less cross-sectional dimensions than the'second portion and a bottom longitudinally inclined from the horizontal at a greater angle than is the bottom of the second portion, the cross-sectional d menslons of sand port ons belng so related to each other and to said: angle of inclination that. a-givenamount of pulp will flow ina given time through said portions respective; ly, and at-beater what one end of. the ma chine forraising the pulpvover said roll from the second portion to the first portion. ,j

In a paper-pulp beating machine, a chain nel for 'fiowing the pulp therethrough having, a mid-feather dividing the channel into successivejportions, the firstv portion venting into the second portion-and having -a.bottom longitudinally, inclined downwardly there intov at a greater angle from the horizontal than the bottom of the secondportion' in- 7 clines downwardly, the mid-feather divi d ing the channel into a horizontally widersecond portion and a; horizontally. narrower.

In testimony whereof I. have hereunto set my hand at Grand Rapids, Michigan, this 'llth day of August, 1929.
