Said prior application Vdiscloses a machine wherein the succession f hooks is advanced edg'ewise and in a step by F step manner, With the rounded backs of the 0 boo is beneath, and the successive books car# ried ina succession of clamps connected in a train; but the present invention is not con# fined to use with suchtype of machine, since 'he book might be carried With it'slb'a'c'k above, U and by means other than a train-df 'clamps for the guidance and advancing movement of the books,'\vhich might in some cases be continus ons in character, although preferably intermittent as in said application. The present invention, like the prior application, is preferably automatic, but is not confined ,to an ap-V paratus wherein the preceding gluing and the succeeding backlining `operations are automatic, vsince the present invention Vis directed more especially to the headbanding step'.v

The general object of thev present invention is to improve the eificiencyand the accuracy.

of foperation in the application of headbands to round back or other books. A special vob# vject is to improve the devices handling the small headbands Y or strips and accurately alining or registering them to'each bo'o'kd-ur-T ing application thereto.

Referring first to certain `general parts;` eachlbookfclamp 10 may comprise a-front clampplate'll and aback clamp plate'i12, the successive clamps being hinged vor articu-latedrtog'ether ina Well-known mannerand guided on longitudinal elements generally indicated at 13. Each back clamp `plate may advance toward the rightiuea xd path; Each front'clamp* plateis; slidingly fittedr tothe back yplate by a spring pressed devicev 14, tending to hold 'the clamp plates pressed strongly upon the book B, but permittingV separation or frontwardy movement of the front plate-to receive and discharge the book.

As is usual in clamp train machines; each book 'B is preferably registered intli'e clar'rp by actual Contact With some partV of 'the clamp', for example-with thedevice 14, or by a-special positioning or gag-ing '15,',arl rangednear the're'ar' or left end of the-clamp; the clamps being movable' toward the' infastep by step manner, each' book beingy held in its clamp with its rear or left edge'Y This may be due to slight variations or lost.

in contact with the pin 15, and with its rounded back extending longitudinally inV the direction of book travel and projecting both plates of each clamp, and there iriayV be a' second pair'of `apertures 11i V spaced therefrom so that the pin caribe shifted from one pair of apertures Ato the other, according to` whether the machine is handling relatively short or long books; so that a short book may take a position somewhere near the iniddle of the clamp.

1n the drawings the d l carrying krelatively short books vB, their rear edgescontacting the pins 15 in the apertures 16, but other means mavv be employed for holding and advancing the books from po- -sition to position. lWhatevcr type or book holding or conveying means is employed there is a likelihood of the successive books coming occasionally to the. operating place orzstation in not exactly the correct position.`

motion in respect to. the travelof therbook advancing means to the headbanding posi, tion, or it may be due to accidental variation` of the position of each book in the'clanip or other'advancing means. Anyfsuch variation inl longitudinal position, even though relatively small in amount, may be highly objectionable in connection with the applica- ,tion of theheadbands to the books, as it is practically vital that each headband, being an ornamentalstrip or finish to each book back, shall be `correctly registered or positioned with relation to the topV and bottom ends of the book, that is, to the forward and "rearward ends of the book-.held and advanced in the manner disclosed. -With the present invention this requirement is met by a construction oflieadbanding mechanism wherein, during the pausey of each book, the

Vmechanism is caused toadjust itself 'to the book, through one or tvo feelers or contacterswhich detect and determine the position of one or both ends of each book, and thereupon control the headband applying devices or the headbands themselves so that the headbands will be positioned upon the books ,inv

the exactly correct locations desired, giving a uniform and satisfactory product. The drive of the conveyor or clamp train may be vcoordinatedwith the headbanding mechanism as in the prior application, through a main shaft 19, preferably continuously ro-v standards are brackets 21 giving support to annaxle 22 on which are mounted a pair of clamps are shown asV supply spools 23 carrying the headband sup- Y ply strip H. The standards extend up- V- shapeiior 'concave forming member 26 Vwhich presses a substantial portion or the entire length of the' headband upwardly firmlyV against the rounded book back, and a holder or suction member 27 in the formv of ahead or' narrow nozzle adapted to receive', and hold eachindividual headbandV during the movenient or lifting thereof to the book but preferablyzeasily yieldable as the shaper comes into action. The'combined

elements

26 and 27 are shown mounted on` a carriage 28 or 23a, the latter at'the right or forward end of the mechanism, the, two carriages being arranged `to rise and descend, also to swing inwardly and outwardly, that is, backwardly andfrontwardly, in unison, aswill be described. Each carriage is continued downwardly as an extension or armV 29 or 29:L i

these terminating in ahub 30 Vor 30@ botli mounted on an axle system arranged to rise and descend. f

The axle of thecarriagehubs30, may have the following special construction toV permit adjustments for varying book lengths. rllhe left hub 30 is mounted on a hollow axle part or sleeve 31, between collars 32 held by set screws 33, the lsleeve and collars being non- Vrotatable but the hub able to rock thereon, and` the hub beingV adjustable longitudinally byl loosening the set screws and resetting the collars according to the setting ofthe pin 15 in the book clamp. The hub 30L is confined between collars 32a pinned to an axle part 3ft which at its left end is extended, reduced and` threaded at 35, this extension passing through the hollow axle part 3l and having screw engagement therewith. Upon turning the

axle part

34, 35 it will adjust itself rightward or leftward and correspondingly vadjust the right carriage 28a.

j For conveniently adjusting thecarriage 28a to any desired position, according to the varying lengths of books, and at the same time making certainV other adjustments to' correspond, a threaded shaft 37 is shown, carrying a hand wheel 38 at its right end, and

turning in a bracket`39., The shaft may be engaged by a nut 40, thus shifted Vright and left to adjust the severing and feeding devices as will be described. The threads on the shaft4 37 may have the same pitch as those on the axle 35, and they may be connected to turn in unison as follows. On the shaft 37- is to and in turn connectedlby a sprocket Vchain 47 with a sprocket 48 which turns the axle partk 34. By this arrangement theturning. of the hand wheel 38 effects the adjustment.

of the hubk and carriage 28a, adapting the mechanism tothe length of the book. The rising and falling movements of the axle sys- 'tem 31-35 and the carriages will be laterA described. Y

Corresponding withv the threaded shaft 37 which shifts the nut 4() to adjust thefeeding and severing devices atth'e right, there isA shown at the left a threaded shaft 51 mounted in a b-racket 52 and having a head 53 by which it can be turned by wrench, the shaft engaging a nut 54 from which the severing and-feeding devices vtake their adjustment.

described. These two complementary adjustments at the left end are not made so conveniently as those eHected by the hand wheel 38 at the right end,or the reason that' .the

shift of thepin 15 in the clamp is rarely necessary, while various miscellaneous variations of book length may be wholly taken care Y of bythe adjustments at the right or forward end by the hand wheel 38 as described.

Returning to the applying device, :supported on each carriage, consisting of shaper and suction holder, the Shaper 26 is shown asa thin plate or bar, with itstop edgeconcave, and mounted on the carriage to rise and Jfall therewith, by the `following mounting. The sha-per plate is shown-as closely adjacent the outer side ofthe suctionrhead but mounted independently-on the carriage.

The lower end of the sh aper 26 is shown as enclosed between Va small upright fork 55 and the upper portion of a yoke 56, all three of them united by a shouldered bolt which holds the fork rigid with the yoke, but permit-sa slight lateral play of the shaper, limited however by a pin projecting from the shaper between the arms of the fork. The lower end of the yoke is rigidly bolted to the upper end of a plunger 57 having a frontwardly ex-l tended head overlyingv a horizontal portion of the carriage 28 and having an interior rod extending-within a recess in .the carriage, as'

seen in Fig. 3, with a strong compression spring58 confined below the plunger, tendlng to lift 1t relatively to the carriage, and

thus holding the'shaper in its operative posi-V tion, under the control of a limiting bolt 59. By this arrangement theshaper is made to rise and fall with the carriage, in a substantially rigid manner, but the strongspring 53 permits a slight downward yielding or cushioning without detracting from the effectiveness of the pressure on the headband, and the relation with the fork member 56 per- Thev manual adjustment of the left carriage28 is made by shifting the collars 32, as already mitting, a slight transverse play assisting the shaper to adapt itself to the curvature of the book, the fork also serving as a convenient means for confining and initially adjusting a suction opening or nozzle 60 for the headband, arranged at the top side of the holder, which has a horizontal extension or shank 61 constructed with an air channel62 leading to the suction opening.A The holder shank 61 is connected by a hollow pivot or stud 63'with the upper portion of the carriage 28, which is provided with extension side plates 64 to enclose the shank and. aiford bearing for the stud. Y

The suction nozzle 60 is for the purpose of holding securely each small headband during and after severance and up to the time of application to the book. As books may have varying thickness the nozzle opening is preferably adjustable in length and :tor this purpose a narrow slide 66 is arranged in a groove t at the top side of the holder, so that it can be adjusted more or less in or out and thus brings the headband to the book the book acts as a stop and on continued rise of the carriage the holder 27 yields relatively downward, while the concave shaper 26 continues to rise and to press the headband firmly into contact around the back of the book, the suction having ceased as the headband contacted the book. The holder spring 67 is of far lighter effect than the shaper spring 58, the function of the holder being completed when the headband meets the book, while the function oi the shaper is to afford strong pressure thereafter.

The suction action and control may be substantially asr follows. A pneumatic hose 72 is shown extending from each of the hollow studs 63 of the respective suction holders downwardly to a common pipe 73 which in turn is shown connected to a pipe 74 which extends toward the back of the mechanism and is connected by a pipe 75 with a control valve 76. The control valve may be substantially similar to that shown in said prior application at Figs. 12 and 13, comprising a sliding bar or horizontal'plate 77 having a suction passage open in one position and a relief passage open to the atmosphere in anconnect the vertical pipe 7 5 with a pipe' 80 leading to an air pump. l

rlhe stem 82 of the valve slide is indicated as being pressed backwardly, or to the right in Fig. 3, by a spring 83 acting upon the head 84 of the stem, `this head sliding in a fixed part and carrying a. cam roll 85 ybearing against the periphery of a cam 86 on the main shaft 19. ln the position shown in Fig. 3 the valve is thrust frontwardly and the suction is in effect, holding theA headband upon the holder. c

The various trains of connections are not shown in corresponding positions in the several hgures, but each train from the shaft cam to the terminal instrument is completely shown, andthe description gives the order or cycln of operation, so that one versedin the art can correctly design the operating cams and attach them to the main shaft in correct j relation.

The bodily lifting and lowering of the headband applying devices may be effected blade by the applierand headband in as follows. their extensions 29 and 20a with hubs 30 and 30a are supported in upright position on the horizontal axle system 31-34 already described. This is a floating axle mounted at the front or` swinging ends of lever arms 90 fulcrumed on the axle 45, which axle. may act as a rock shaft, having a rearwardly extending rock arm 91 carrying a follower or roll 92 bearing against a cani 93 on the main shaft 19. The axle part 31 is fixed against rotation in the left lever arm, being internally threaded and acting as a fixed nut for the threaded extension 35 of the axle part 34, which latter turns in the forked end of the right lever arm, and has a keyway by which the sprocket 48, between the fork ends, main` tains a sliding keyed engagement with the axle.

ln the position shown the front ends of the arms 90 are in downward position, the cam roll being in lifted position, and a spring 94 may be arranged at each side to hold the parts in this position, with the'roll pressed against the cam, and the cam being adapted upon further rotation, to force down the roll and thereby lift the front arms, the carriages and the headband applying devices, to place the headbands upon the exposed back of the book.

Preferably the applying devices, the Shaper and the holder, assume a back position during the reception and severing of headbands, but with the carriages shift or swing frontwardly therefrom during the rising motion to apply the headbands to the book. This permits the shearing type of severing device to be used, and avoids confiict with the front the lifting motion.

The following described device may be employed to cause' the frontward swinging of the carriages during their elevating moverEhe carriages 28 Vand .28a and ment. In a boss or enlargement formedY at the lower part of each carriage, at the top of the

extension arm

29 or 29, is mounted a bolt or stud 99 extending rearwardly, the rear Y end of each, 4bolt carrying a follower or roll100 adapted tok move along the surfaceofa fixed cam 101. Each of the cams .101"is ofY substantial width, as seen in Fig. 2 so as to cooperate with the follower inall :adjustments for book length, and each cam has a lower and an upper surface, Vwith a decided incline between them', so that in rising from the head` band receiving position the carriages andV and under a guard plate 105 and thence up-V wardly and rearwardly, each passing around an idler pulley 106 or 106a. The feeding devices at the forwardv and rearwardV ends are substantially duplicated, the former carry! ing similar reference numbers sometimes with the exponent a, and each set being adjustable independently and in a dierent manner from the other set. The construction of the forward set will be first described.

The idler 106a may constitute a guide pulley, with flanges, steering the headband strip correctly to the feed rolls, and itself adjust? able longitudinally for this purpose. The headband passes from the'guide pulley horizontally frontward between a lower feed roll 108a and an upper feed roll 109, The lower feed rolls may be mounted upon so as to turn with a shaft 110 and may adjustably Vslide thereon, while the upper feed rolls are mounted upon a shaft 111 on which they may slide. As shown in Fig. 3 the upper shaft 111 may be mounted on rock arms 112 having a fixed fulcrum 113 permitting the upper feed rolls to be lifted bodily at will for insertion of headband strip, gravity normally holdingv them down upon the lower rolls.

The rearward or left pair of

rolls

108, 109

are adapted to be adjustably shifted bodily along the direction of book travel by means of. the threaded shaft 51 manually rotatable to give an adjustment to correspond with the position of the rear end of the book determined by the position of the clamp pin l5. The connections for this adjustment may comprise grooved hubs 115 on the feed rolls,

with fingers 116 engaging them extending from the adjusting or knife carriage 137 to be described. y Y v Likewise the forward or right feed rolls 108% 109a are adapted to be bodily shiftable along the direction of book travel, by means of the threaded shaft 37 turned by the hand wheel 38, Whi ch also has'sprocket connections for readjusting lengthwise the position of the carriage and headband applying device. The connection by which the shaft 37 effects the adjustment ofthe forward feed rolls may comprise grooved hubs 115a on the feed rolls with fingers 116a enaging them, extending from the carriage137a tobe described.

In order to turn in unison the

two'feed shafts

110, 111 they are shown at the left end as provided With intermeshing gears 121, 122. By rotating the shaft 110 all `of the feed rolls are turned in unison. This actuation-,may be substantially asin said prior application, and briefly referred toras follows. Loose on the shaft 110 is indicated a gear 124 constituting one member of a roller clutch or one-way drive device, the other `member consisting of a 4clutch member 125 fast on the shaft 110. Below the toothed clutch member 124 is a horizontal rack 126 vreciplrocable to oscillate. the clutchrmember, thereby causing intermittent forward rotation of the shaft 110 and the four feed rollsf vThe parts thus far described are shown'in Fig. 2. The rack has a rearward extension 127 shown'in Fig. 3, this being moved forwardly andrearwardly. by an upright rock lever 128 fulcrunied on a rock shaft 129 which `cai-rieL-z also a cam arm 130 at the extremity of .which is a follower or roll 131 engaging a cam 132 on the main shaft 19. A spring 133 is `arranged to pull frontwardly on the rock lever 128 thereby holding the cam roll to the cam.

With this arrangement each rotation of the cam moves the rack 126backward and front-f ward by a predetermined extent, the backward'movement bythe cam operating to Arotate the feed shafts and rolls and thereby advance on to the appliers suicient strip to form new headbands, the return movement of the rack by the spring 133 being idle on 'account of the character of the drive clutch. "The'feed for the headband strips is to be timedv to be completed before suction is. applied to the holder and before the operation of the severing devices. Adjustment of the'extent of feed and length of headband may: be eected by a stop rod 134, seen in Figsy2^and 3, its threaded front end turning .in affixed nut or sleeve 135, so that by a suitable handle the rod may be adjusted, for example backwardly, or to the right in Fig. 3, so as to limit and shorten the frontward movement ofthe lever 128 and thereby; reduce the return' bands. n 1 Y r f .For theV purpose of. accurately alining or .140 and an upper blade141, preferably the lower blade being relatively fixed on the carriage, while theupper lblade swings downwardly to sever or shear the-headband. The

Aswinging blade is pivoted to the fixed blade by a pivot device 142 comprising spring means to maintain cooperating contact and pressure. The movable blades 141 have, each at its inner end, actuating pins 143, and these two pins are` shown as both engaged in the elongated horizontal greove 144 of a baror cutter .actuator 145. Y

The cutter actuator bar 145 is mounted atv the topend of a carrier or shank 146 slidable vertically in fixed guideways, thelower end of the sliding shank being curved backwardly'as seen in Fig. 3, and connected by links or shackles 147 with the front en'd of la lever 148=fulcrumed on a-iixed axle'149, the rear swinging end of the lever carrying a roll l15'() f engaged .on the periphery of a cam'151 on the main shaft 19.. The cam is shown as having elevated the roll an'd depressed the-carrier and actuator bar and thereby.` cut the headregistering each ofthe headbands with the disclosed. A.y movable registering device is employed, `the same having a feeler or contact part adapted to'be moved into contact Vwiththe endv of the book and so determine the lband upon the applier as they come. to applying position .j 4 A While the registering devices may take. different forms each of themisshown-as a lever 170, extending substantially vertically, and arranged Vwith a `fulcrum171 near itsmiddle by which it is adapted tomove to 'and from contactwith-the book. For example the registering Vlever may be mounted upon the'headband' applier carriage 28,` so that the lever will bodily rise and fall and swing frontward and back with theca'rriagel In this way the -lever'is broughtto position where it can make contact with the end of the book', such contact being effected by swinging about its ownl fulcrumina'plane parallel to that of the book.

u The operation may be as follows. As the two appliers under timed,v controlgmove'or rise with theV carriages 28, 28a, they bring the h-eadbands to the book, the-'headbands being held in position on the' applier bythe suction, which continues from before the severing until just an instant before or as the headband reaches the book. VThe camedge 176 of each registering lever, bearing on the roll 1-7 9 holds outward or retracted the upper end of the lever Luntil, asgthe carriages rise thel edges 176 ride off the rolls, after the feelers 172 have risen above the level of the book backnso that the leversare then released under timed control and allowed'to swing interins are to be similarly considered.

As a final result the headband Vis necessarily correctly applied to thebook, with its outer Yor beaded edge overlapping the end of the book backby the predetermined amount. Y

c In describingthe illustratedr embodiment i the carriages and headband appliers "have been referred to asbeing lifted or moving upward'lyl towardithe book; this however not beingintended as a limitation to the illustrated relation between the book and the apply,- fing mechanism, since the latter need not necessarily operate `frombeneath the book, but mightoperate-from a different direction, .so long as the vapplying action is infadirection toward the back of the book. @ther relative IThe registration feature hereof is applicable to any strip or component to be applied to a glued book-back, such ,as the baoklining which'follows the application of the head- Vbands, which must vbe correctly positioned lengthwise on the book back and which, as its applier brings it to the book may be registered at one or-both ends by a device lcomprising the feeler and theadjuster of the present invention ,operating to adjust the `component upon Vthe applierso that it will be appliedcorrect-V ly tothe book.
