This invention relates to a heater roll and is designed -more particularly for useas a part of a beater engineof the type commonly employed in the preparation of paper pulp cured about'the peripheral edges thereof a.
1 and the like. prise a plurality ofsupporting members 1'07:
Such beater rolls usually comtatable about acoiirmon axis and havingiseseries of bar's usually oalledfly .bars,= 'which cooperate with-a fixed bed plate-Q The'roll and bed plateare mountedin atank inavhi'ch' the. pulp stock, or material fro n vvhich the pulp is to be formedfls floated in water the arrangement being such that the liquid and stock will circulate through the tank andbe-v tween thebeater roll and the bed plate wh'ere the stock willflbe comminutedlg With this type of beater roll diflicultyi has been lexperi enced in :properlysecuring theflybars :tothe supporting memberss One :method; of acf' 'complishing this has been to provide the several fly bars with lugsor parts projectingbeyond the respective.- supportlng; members at the ends-of the roll and to :shrinkw-ahmetal ring about these pro-jectingwparts This method of mounting :thebarsis objectionable. for several reasons." For example, it.-is:cliifi' 'cult to assemble thebarsabout thesupporting menibers and retain the same in thelr proper positions prior :to and during the shrinking of the ring thereonlf Fuiztherpif' the ring breaks all the bars arezreleasedh One object of the presenttiiiventionisto provide a device of this character having means whereby the bars may beuquickly andeasily'attaehed thereto.' a.
further object-of the invention is to provide. such a device in whichthe fly bars may be mounted thereon'either individually or in pairs, ,th'us avoiding the necessity of assembling all the ba s about thei'support:
ing members before any'f of the bars are fastened, and also permittir ig the removalv of a single baror -a pair of barsi'without i the necessity vofremovingany other ba rL, T1

In thesesdrawings lxhave illustrated on embodimentofmy invention .and'haveshown the same as embodiedin the roll\or ,.drum of IE abeatingiengine. It willbe understood.- that this particular construction has been chosen for theqourposes of illustrationorily and thatxtherinvention may take various forms and may-the used in connectionwithmachines 1 ofr varionskindsh -i r v 1 'In 'theflpartic'ular embodiment :here illustrated'the beater roll. comprises a plurality of supportingxmembers .or spiders, these supporting members being here shown in the 75 term of disks 51 rigidly mounted on aeshaft '2 which may be mounted and rotatedlin any suitable manner. that form here shown the beater roll hasibut two Isnpportingmemhers, I these being arranged at the respective ends of the roll. a :Rigidly securedto 'the'two supportingmembers or disks landextending lengthwiseaof the beater troll are a series of attaching membersior bars 8'whichare'spaced one :from the other and the outer :portions' of which project'rbeyond the peripheries; of the supporting members. These vattachingbars may be secured to the supporting members inany suitable manner'but, in the present nstance, each supporting member .is provlded 1n:1ts perlphery.

Inthe construction vhere shown; the, attaching bars are inserted kin the "slots with a driving: fit
and no other fastening means are necessary.
Mounted on the respective attaching bars are fly bars 5 which may be secured thereto in any suitable manner and which usually extend for the full length of the beater roll. In the present instance, the fly bars are arranged in pairs, the two fly bars of each pair being secured to the same attaching bar. Preferably the fly bars of each pair, which are arranged on opposite sides of the attaching bar, are rigidly secured thereto by means of a pin 6 which is driven through openings 7 in the fly bars and an opening 8 in the attaching bar, the fly bars may rest upon the peripheral surfaces of the supporting members, thereby relieving the pins of a substantial portion of the stresses to which they would be otherwise subjected. The fly bars have the inner portions of those surfaces adjacent to the attaching bars inclined to conform to the inclination of the corresponding surfaces of the attaching bar and have their outer surfaces flat, so that when secured to the attaching bar each fly bar'will extend substantially radially with relation to the beater roll.
The attaching bars are so arranged that adjacent pairs of fly bars will be spaced one from the other, and arranged between the adjacent fly bars of adj acent pairs of fly bars are filler strips 9 which serve to close the spaces between the fly bars and to brace the latter one against the other. Preferably these filler strips are of wood and are fitted snugly into the spaces between the adjacent fly bars while dry and when immersed in the liquid in the tank of the beater engine they will swell so as to exert lateral pressureon the fly bars and press the same snugly against the attaching bars, this swelling also being suflicient to retain the filler strips in position, although other fastening means may be provided if desired. 7
