1,400,228 that a spreading or contractinu movement of the blades 20 can take place - ,without involving any endwise movement of either drlim section on the. shaft, - which is impossible -where the blades' or flanues are directly mounted on the inner - or proximate ends of the drum sections. On t-he in-ner face of the disk 19 is a, shallow circular recess 23, and On the corresponding face of the disk 18 is 10 a, circular protuberance or boss 24 that spans the space between the inner edges of t-he blades 20 and forms a, bottom wall for the annular space or channel between said blades, for a purpose hereinafter expl,,tined., 15 251 26 ancl '/-)7 designate three rollers grouped arouiid ,tnd disposed parallel . with - the drum, and having their gudgeons journaled in suit,,ible bearings in tlie side-frame members 10 aiid 1 1. On a rod or shaft 28 20 mouinted in and bet-ween the side-frame members tbove the drum are loosely mounted a pair of roller sections 2(), between the xima'Le ends of which is also loosely pro mounted on the sbaft 28 ,t cutter dislc 30 25 more particularly herein,,tfter described. Pivoted -It 31 (Fig. 1) to: the outer sides of the side-fr,,tme members 10 and 11 is ,i swingino, frame comprising parallel uprioht bars 32 and a cross-connecti-lig bar 33, ancl 30 in the upper end of 'uhis fran-ie are journ,iled thegtidge6iis of another roller 34. Trained around the rollers 29, 255 2q, 27 and 34 and the m,@ijor portion of the circumference of the drum secti6ns a-@:e t series of endless 35 bookin(T belts herein showii as six in -num-@ oreater 6r less n mber may ber although a @, u be employed, said belts being desioiiated by 35. Thepivotedframe32,33,andtheroller arried there34 and portion of the belts 35 c 40 by ire usually, iii machines 6f this type, desio-nated as the apron of the machine. The @several belts 35 ar6 individually tensioned by -independent tensioning devices most cle,,trlv show-ILi in Fip,,s. 2 and 4 and each 45 COI]aprisino, a leier 36 pivoted on a rod 3.7 mouiited in ,ind bet-ween the upper rear corners of the side-frtmes 10 and 11, the forrdly projecting ,.rm of the lever , carryin wa, 9 a roller 38 engauiiig beneath the upper or 50 olit@er@ lap of th@'belt, and the rearwardlv projecling ariii of the lever carry@iiig a suspeilded weight 39 adjustable toward and from the pii,ot of the lever b37 notches 40 engra,geable -vvit-h the hool@ed stem 39' of tl-io 55 wei(yht 39. By this means all slack in the beICs iscop-tini-iously t-.ken iip, and the inner or drum-enpanin(, la-o of each belt is allowed to, expaiid under proper tension as the book is btiilt up between the belts and the surface 60 of the drum. The cutter disk 30 is preferably of polygoTil I form in@,,)eriphefil outline, ,is shown in 2, and its peripheral portion lies betiveeii the drum bl-,Ldes ot fl,,tnges 20 so as to 00 @ffect a shearing a6tion with the latte-r on opposite sides of the stem of the leaf. The cutter disk is rotated wholly by the frictioii of the blades 20 thereon, tnd ihe periphery of I the disk is preferably , chaniielecl or grooved, as sho@vn ' Figs. 1 and 4, to give 70 in it a guiding action-@on the stem and caLis(@, the latter to track properly with the, cutting mechanism. It will be @bserved by re.'Lerencle to Figy. 2 that the cutter disk 30 is so locat6d in advtnc-e of the nip of the bookiD.-l' 75 belts and drum tb,,tt th6 severing of the stem t,,ikes place before the portions of the leaf on either side of the etitter have passed ip-to the grip of the belts and drlim. This I regard as an important featlire' of the present 80 invention, since, by avoiding the, tr,,t--q verse stretching of the leaf by the inner belts over the projecting drum blade@s or flanges before cutting, I avoid-the ru-ottire and tearing of the le,,tf that frdq-Liently occurs ui@cler such 85 conditions. The drum - blades or,@ flanges 20 are uiiiormly spaced. apart against the action of the springs 21 and 22 by three spacing rollers 41 ' best shown in Fig. 2; oiie of whicli 90 is loose on the driving shaft, hereinafter referred to, tnother is loose on tlie belt roIlLer 27 and the third is loose on I cross-rod 42 di@ectly over the drum. These spacing rollers, th'@ peripheral portions of which eiiter 95 betwee'n the blades 20, are of stibstanti,,tlly the same thielmess as the clitter disk 30. Keyed on one of 'the tie-rods 12 of the Mach . ine frai-ne is t:sleeve 43 havin- ,t flattened upper side, on @ -which is mounted a 100 device f r ejecting th sever cl t6i7,ls fr 0 e e, s o.-n betiveen the drtim fl,,ino;es@20. This. stemejector, which is best shown iii the r(red detail 'ews Fios 5 a d 7 vi n is t generallv scissors.-IiIi:e device, comprising a pair o-L 105 overlappino- bl,,td-_s 44 and 45 moiinted by a pivot-screw 46 on the sleeve 43 and provided with rearwardly extending handles 44' -nfl 45' resi3ectiVelv, connectecl-- by a @IL-el)-s;,Ie spring 47. The forward end -,)ortio@is oL the 110 blades 44 and 45 etiter the pa6e ioetwe.n the drum flanges 20 and at t,heir en,-Is rest on the periphery of the disk boss -or prot-Liberanc(,, 24 whicl@ forms the bottom wall of the annular chann-@l @formed by saicl fl,.tnges. This 115 bottom wall limits the deptli to v,,Iiieh the severed stems can enter bel6-w the pe,-i-phery of the drum, and as each stem, dilri-Lag the turnin(r movement of the drtim, e.,-icounters the ejector blades or fip-o-ers 44 and '5 ' it is 120 directed outwirdly by and over the lptter, 00 falling to the fl r or into a slli-t,,ibl-@ receiv,-,r in rear of tl-ie machi-Tie.

When books of the requirecl size have thus been built up, i 0 the machine is stopped, the apron is unlocked by manipulatidg the turn-button 55 to reti@act the locking bolts 151, the apron is swu:ncr outwardly to the dotted line position sb-ow@ in Fig. @, and by a sliaht baclcward i 6 tlirnin" movement of the dru-m the booked leaves, mty be readily -withdrawn from the -Lront of the machiiie. I have- fo-Lind that by cutting the stem in advanc-. of the point at - which tl-ie leaf is 20 gripped and dra-wn into tl-ie machine, the tr,,ti,isverse stretching of the leaf by the iniiei,mosl@- belts, v@nd the coiisequent cia,-nger of tearing the same, are avoided, so that the suem emerges clean and with practically no 25 'k v-aste leaf adhering thereto. The polygonal form of ctitting disli:, driven by friction corit,,tct with the drum bl,,tdes effects a more per-Lect shear clit than a circular disk, although fair results are obtainable with the latter. 30 The cuttii-ig effect is improved by means 6f the spteing r6llers 41 bet-ween the drum blftdes, since these spacing rollers maintain the outer edges of the drum blades in perfect p,,trallelism throLigl-.iout, and insure a close shetring ,tetion bet-ween the co6perating edues of @uhe d;-sk -,nd the blides. The stem ejec-tor ro' o-illi, ef@ic-tently performs its main flinction of e:ecting the stem, but it also, @bliroiigh its scraping action on the inner faces 40 of@ the clrum bl,,icles IKeeps the latter clean and ;-'ree from accumulations of gum. The m,,t-@idrel or core 24, by sp,,Lnning the space bet-we-In the inner edcres of the @nnLilar blades 20, prevents the stems from lodging and ae45 cumulatiii in the space bet-ween the dr-Lim - re th sections.
