To all whom it may concern: Y Be it known. that I, ALFRED BREDENBERG, a citizen of the United States, and a resident f Champlain, Clinton county, New York, have invented certain. new and useful Improvements in Bookbinding-Machines, of which the following is a specification.

The present invention relates more espe cially to bookbinding machines operating on the trim-and-glue system, and involves a transferring mechanism adapted to assist or render automatic. certain operations of such binding machines; although features of the invention might be equally useful in various 16 other kinds of binding machines.

The invention has for an object to provide a means for successively transferring a series of objects to be bound, such as signaturegroups, from the deliveryv of a gathering 20 mechanism into justified position within o series of clamps, foi such binding or other opera-tions asare to be per'formed upon the same; the gathering and binding mecha nisms being thus operatively associated into a single book making machine; and other and more specific objects will appear heref inafter in the following description or will Abe obvious therefrom;

The terni signature-group shall be used 80 herein in a representative sense as including any analogous object consistin of assembled components, such as a pi e of single Sheets, designed finally to constitute a book 01-,analogous article, such as a pad. My'

$5 automatic combined gathering and binding machine, however, isadapted to operate not merely upon sin le sheets, or onceffolded sheets, or leaflets,V ut the regular commercial si ature, which I will refer toas a multi- 40 fo d? signature, in which the printed sheet'I is folded at least twice, and usually three ory more times, resulting in two,l vfouigor more folds at the back, with fourlofnlmore sheets and eight 0r more pages in signature.'

.My prior Patent 1,177,600 ,shows-:almacenanism adapted to gather and automatically deliver a procession of groups ofl loosely assembled multifold signatures, and my prior Patent 1,073,324 shows a procession of 5o clamps, and devices ada 'to b1n d together eachroup of mu tifoldlgnatures, na/melv,jby t systemofltrnming oil the lds to "expose every individual Sheet,v K-

and then gluing together the back edges of*v all of the sheets, and then usually reinforcing them by applying a backing over the glued edges. The present invention in one aspect is a completely automatic book main ing apparatus, in which are operatively united the essential features of gathering.

and binding mechanisms such as those of my said two prior patents.

y Mechanisms are Well known, and l do not make claim to the same, wherein groups 'of signatures or sheets'issuing from a gathering, collating or assembling mechanism are "wire stitched, that is, secured together by staples, While under compression, the book in some cases being held stationary and in others kept in motion, the stapling devices in the latter lcase being either rotated. or iev` ciprocat-ed, so as to driveethe staples during the forward book 'movementg while trarily to all of these lthe present invention pertains more particularly' to the very diil'en' ent kind of book manufacture which. yieids a flexible book, namely, by what may be specifically described as the triin-and-glue system.

` IV believe that in 4the presentinvention l am the rstto produ a completely automatic gathering and binding apparatus in which multifold signatures may be gathered and delivered in a procession of groups, and thereafter conveyed forwardly under secure clamping pressure, and with back edges protruding past! a device for trimming ofi' the back folds, and thereafter a device for applying glue to lthe trimmed'bacli edges, andA usually a subsequent device for applying a backing or cover to the glued edge, before` the settingl of the glue and discharge of the bound book.

The present invention consists in the novel arts, constructions, contrivances and comvbinations hereinafter shown or described.

Dcsaptio'n of thawing/s.

The accompanying drawings referred to in the following description and forminga part hereof, illustrate one embodiment of the present invention, the sameserving in connection withv the descriptign to explain the principles of the inventiotia1 In the dra-Win s, Figure 1 is a front elevation partly in tion ,of parts of a book bindingvmachine,V including a` transferring mechanism embodying the present improvements. Fig. 2 is a rightliand elevation partly in section taken substantially on the plane 2--2 of`Fig 1. of themechanism seen in Figs. yl and 2.

Fig-'4 is a front detail view of one of the contrivances shown in Figs; l, 2 and 3; Fig. 5 being a similar view of the same in a different stage of operation; Fig. 6 being a righthand view thereof.

Enumeration of features. c

The present invention involves a book binding machine including in combination a signature gathering mechanism,` a binding mechanism comprising a clamp, and means` intermediate said gathering and binding mechanisms for transferring each object (signature-group) from the delivery of the gathering mechanism to said clamp; each of the objects being during its transfer, in the preferred embodiment, swung from the fiat- Wise position in which it is delivered by the gathering mechanism to the position (upright) in which it is moved into the clamp. The terni clamp is used in a sense to include equivalents.

Especially the invention is directed tothe successive automatic gathering, clamping,

trimming and gluing of the books, to give -iso ' includes the following features:

flexible binding. v

Also, an important feature is that the path of transfer or infeed to theclampv is a rising path, so that the book approaches the clamp at a substantial angle to the clamp travel, and is thereby accurately introduced into the clamp, clamp operation. More specifically looked at the invention The `transferring mechanism hereof comprises a distinctpart which may be termed a holding member or holder which is adapt ed Ito have the objects (signature-groups) fed into it one at a time, combined with a moving member for moving or lifting cachv vsuccessive object from the holder into enga ement with a clamp or the like.

ccording to another feature of the in-' vention the holder is of such character as to receive each successive signature-group or other object iatwise and thereafter swing or tip upward into substantially upright position pre aratory to a vertical (preferably ascendlng clamp or the like.r

According to still another 'feature a movi ing orliftin member is contemplated which engages wit the Vobject in the holder. and moves bodily from the holder (upwardly or downwardly) `.tow-ard theclamp, carrying th'e object thereto.

According to still another feature is con` templated acontrivance for shifting the oball in properl time with theniovementl of the object into a r jects to the holder, comprising an arm or finger which reaches out foreach succestion in the holder this contrivance shown as cooperating with the delivery of a gathering mechanism.

According to still another feature is contemplated a certain clamp-operating con-` trivance which serves toiopen and close a clamp in harmony with thiJ operations of the other parts of the mechanism.

As further features of the presentinvensive object and 'draws it into proper posi- Y "tion are justifying or registering stops: serving to insure the accurate positioning of each object so that, when it has been engaged in the clamp for any desired subsequent operations, it will occupyY the. precise neces' sary position.

Each of the features of this invention above referred to is thought to be novel in itself and also wheniemployed in conjunction with the others or other of said-features. v The above and other features of the invention will` be more particularly set forth in the following detail description ofy one instance or embodiment.

Reference will now be made to the em- 'l bodimelit that is illustrated in` the drawings, hereof, in whiclia signature-group Z is indicated as' the object handled bythe mechanism.

General parte of machine. l

Some of the main portions of the machine, as to which per se no claim of -novelty isA herein directed, will first be de.-

`scribed, andthereafter the novel mechanism illustra-ting the .present invention will be set forth. The machine has a frame A carried on a base A', and certain specific frame parts that coperateI with the Vtransferring mechanisin willlbe hereinafter described in connection with-the latter.

Binding mechanism,

The binding mechanism maybe mounted on the frame and base A, A, separate from the gathering mechanism, which mayhave an independent frame and base, so that my complete apparatus consists of two units connected by a transferring conveyer.

I n the upper part of the frame isan upper guide B and lower guide B shown in the vform of channels adapted to receive, between them and guide a carrier of any known design comprising clamps C,- Cf, intended t0 hold a book, signature-group or other object#v to betreated. The said guides and carrier( constitute a convenient and well-known means of successively presenting a Series of signature-groups to the various instrumen-1 talities comprised in a book f `binding machine; and for convenience there may be l-n extended series or procession of clamps .con-

either side of the machine and a curved connecting portion at either end. The arrow b indicates the direction of travel of the carrier; and several clamps are indicated in Fig. 3vin dotted lines in addition to the one which is in coperation' with the transferring .mechanism forming the particular lbject of this invention. Thus C2 indicates a carrier clamp which has been opened to release a book that has completed itstreatment; C3 and C indicate the succeedingr positions in which the clamp has closed. The clamp C, C', shown in coperation with the present invention, is indicated in open position. When a clamp has been opened .it is preferably closed by means 'of springs sutliciently powerful to lllold the object firmly Wit-hin the clamp during the book binding, covering or other operations which may be performed.' Connected to the outer clamp part C for this purpose are a pair of rods or stems' c, c', which vextend through apertures in the inner clamp 'part and are encompassed by helical springs c2 having considerable length so as to secure substantial uniformity of pressure for varying thicknesses of objects. At-.the inner ends of stems t', c', are heads c3, 03, adapted to be`pressed upon by a means which Will be hereinafter described, for the purpose of sliding the stems outwardly and opening'up vthe cla-mp against the resistance of the springs c2 which subsequently close the clamp. J

The above will be seen to be'a substantial description of the binding mechanism `of my prior atent 1,073,324, the nature and operations of which may be ascertained by reference to the prior patent. After entering thev clamp C at the eeding-in position, eachsignature-group is carried advancingly around the horizontal, circuit shown and pastthe several devices for Vperforming operations on the group. The clamp C is shown of the t 7pe of my Patent 1,073,324 and very: power ul in that the opposed plates are drawn together with a para lel movement through front and rear guide studs. Each cla-mp takes a group of unfas'tened, signyatures'from, so as to dis-- engage, the transferlgneans, and holds the same with the signature back folds free or protruding to permit the trimming and other. operations: Thel several clamps are guided and advanced to move past, that is, to end beyond, the trimming and other devicesjso as 'to' carry the books from one Operation to another,'the `clamps thus con-` `atituting a seriesor procession, moving' 1n fore be designated a delivery support D',

an endless circuit, forwardlyfonly, rather than to andffro along a linear path".

Get/lenny l Portions of a gathering machine or mechanism are shown as illustrative of various mechanisms in conjunction with lwhich the present invention might be employed, and such gathering mechanism will not be described in full detail as it is the subject of protection ,and description invanother application filed by me, April 28, 1911, Serial No. 623,872, which has since resultedk in my aforesaid Patent 1,177,600. A gathering mechanism is one which from supplies of signatures or the like selects one of each' variety and assembles them into a signature group, the actual assemblage being performed if desired upon a support or carrier along which the assembled books are caused vto travel. Such a support D is indicated in Fig. 1, it being slotted and having a traveling chain or sprocket d projecting through such slot, so as to stand above the support surface.

The support and' chain extend through the gathering mechanism and are continued soA outwardly considerably beyond the point Where the completed group issues from the machine, this being for the purpose of conveying the group from the delivery point and transferring it toward the binding mechanism clamp.. vThe sprocket chain d passes around a sprocket wheel d2 mounted on a shaft whichv has another sprocket wheel engaged by a second sprocket chain cl3, which in turn engages sprocket wheel d4, mounted on the same shaft X as the bevel gear Wheel hereinafter to b'e referred to, from which the sprocket chain d obtains its motion. A flange Il along the lower edge of tlie inclined carrier or support D is contacted by each assembled book and keeps the same from talling from the support.` Each pin d on reach? ing the sprocket Wheel Z2 passes downwardly out ofthe slot, and the accumulated signatures or assembled book in front of such pin isj thereby delivered at the left end of the support D, which left end may there-v Portions of'thef mechanism to which the present improvements more particularly relate, will -now be described.

v l Group tmfrwfew'mg means. I I will first generally describe the operation 'of transferring the successive .groups from vthe gatherer to the clamp. The ldelivery of along toward the'binding mechanism. Fr'om\ this point the outer continuations ofthe suip-` 4 group toward the delivery support D', and,

port D and the chain d serve to conveyifthe as' will be explained,..the conveying is then taken up by a reaching-outcontrivance F,

which pulls forwardly the group upon a" holder E,H the holder then` swinging the group upright, and a lifting member J then conveying the group directly intothe clamp. Each group, therefore, is transferred from the gathering machine delivery to theA clamp by conveying means comprising four parts, the extensions of the supportkk and `traveling chain, the reaching-out contrivance, the

Swinging holder, and the liftingmember;

and during the transfer is swung vfrom flatwise to upright; but I do not limit myself to such 'particular means of transferring the successive groups from the gatherer' into the clamp. Having described the extending support and chain' D, d, I will describe theY remainder of the transfer means.

.Group holder. i

' Attention is rst directed to the member E, which is adapted to have the signaturegroups or other objects successively fed to it prior to their being moved therefrom to a clamp or the like; and said member E may for convenience be termed 4afholder, since it receives and holds each object intermediate the two described movements of the latter. The holder E is arranged in line with the delivery support D before referredto, that is, 'so as to hold the'assembled signatures substantially atwiserand as seen in full lines in Fig. 2, the holder E and consequently the delivery support are not exactly horizontal but substantially inclined .for a purpose Iwhich is only incidental to the pres-4 ent invention, and insufficient in extent to change its character from what it would be if normally strictly horizontal. The holder E is seen in Fig. l in dotted lines, and it is clearly seen in Fig. 3 in plan view to consist of a platen actually shown as divided by Va slot e into a main portion e and a smaller portion e2, the slot being inclined at least at its upper end and serving a purpose which Will'hereinafter appear. The objects having to be` fed upon the holder E from right to left, it is. provided at its leftedge with a flange or stop preventing overtravel of the object and serving to adjust it into proper registration for further action upon it. The holder E has a backv plate or support e?, whose fitting will be hereinafter tlescribedf At the inner-lower' edge of the holder is indicated a flange or stop e preventing the objects sliding off the inclined holderfsaid flange being in line with and forming substantially a continuation of flange .d5 of the delivery support D.

Having'thus identified the holder E, ref erence -will now be made in order to the following, namely: a contriv'ance which serves to reach out to the delivery support and draw each object upon 'the holder; a means'of efectingcertain movements ofthe holder E for cooperation with the means hereinafter in this paragraph mentioned; a

means for ymoving each' object from the` holder E into an open-clamp;l a means'for causing each object upon entering the clamp to move laterally or in its own plane for purposes ,of adjustment to certain stops; and a means for causing the opening and closing of a clamp in harmony with the other instrumentalities.

Reaching-Out contrioances.

The reaching-out contrivance comprises a swinging arm FY carrying a hand F on which is a finger f, these parts so located that the finger is capable of extending up through the slot of the delivery support D behind a signature-group or book for drawing the same forwardly on to .the holder E.

The arm F is secured to a' sleeve f2 loose.

upon a stud f3, which is fixed" to the-frame of the machine, as indicated in dotted linesy in Fig. 3,' and is incapable of rotation. The

- hand F is pivoted at f* to the arms upper end so as to be able to swing to a slight ex# tent to permit the finfrer f to be moved out of and into the slot of, the delivery support.

To swing the arm F there may be em.

ployed a link f5 connected at one end to such arm and at the -other end to a lever f" turning about a fixed ivot f7. The link f5 is provided with a spring f8 tending to pull it and the arm F to the right, Figs. 1, 4, and 5, and the'lever j is provided with a roller 7' adapted to engage the surface of a cam f1 mounted upon a shaft X; By the rotatiol'i of said shaft the lever f and arm. F are oscillated to and from the positions seen in Figs. 4. and 5 respectively, and during such oscillation the movements of hand F and linger f are controlled as follows.

Mounted on the fixed stud f3 and capable of.

turning thereon, is a sleeve f which is provided with a tightening device fm by which,V

any desired amountof friction between the sleeve and the shaft maybe secured. The friction sleeve is held in place on the stud by two collars f2, f2, on the latter, and between one of said collars and aycap f at the end is heldi the `oscillating sleeve f2 that carries arm F. V

The. friction sleeve f constitutes part of the mechanical. movement for causing the .finger f on each instroke to pass into book engaging position in the slot and on each outstrokc to swing downwardly out of such position. The connections lbetween friction 4.

sleeve fu and the finger f vcomprise an arm f secured to the sleeve f and having pi'voted to its extremity a short link f, whose other .end is connected to one arm f of a two-arm lever in the nature of a bell v14a-isa crank, having a rotating stud fw projecting from arm F, and whose other arm f in turn has pivoted to it a long link j1g extending upwardly to where 'it is adjustably pivoted at f1 to the hand F that carries at its'extremity the finger f. Fig. l represents the parts as having just reached the end of the instroke, and they are about to return outwardly or to the right.' The friction of sleeve f1? temporarily renders it substantially stationary with stud f3, Se that through link f the `movement to the right of arm F effects a slight oscillation of the bell crank f1, f1?, and a pulling down of the link 7 and consequently a lowering of the finger y' out of the slot of the delivery support. A stop f on arm F limits the hell cranks rotation in this directiontits rotation in the opposite direction being limited in a manner that will hereinafter appear. The swing of the bell crank is in sufiicient to permit the friction sleeve and arm. f to remain stationary throughout the entire swing of arm F, and consequently at 4a certain point the sleeve f commences to overcome its friction and it thereafter revolves with other swinging parts until the position of Fig. 5 is attained, 'this being the limit of the outstroke. Thereafter on the returnmovement of the parts the friction of sleeve f again takes effect to hold said sleeve and arm temporarily, this having the elect of actu, .ring the bell crank to rotate toward the right in Fig. to a considerable degree, and indeed until stopped by the .dh A finger f hing its book-engaging vposition. 'll e i r f is not forme-d directly on,

vthe hand Q'L-'"zb.1in, as seen in Fig. o, is substantially offset therefrom, the hand and finger being connected by a roller f2s; this arrangement permitting the finger to enter the slot of the deliverysupport, butpreventing the hand from entering it, and the roller f2s serves as a stop coming into contact with tl e edge of the slotted support or a. track f2* thereunder, and preventing the linger rising above-the 'position seen in full lines in Fig 4 and in dotted lines inFig. 5. As soon as the roller f23 has been lifted with the fingersuliiciently to contact the delivery support, the friction sleeve as before commences to revolve with respect to the stud l f3. 0n the instroke the roller fi"3 will slide along immediately beneath the delivery support and maintain the finger f throughout such` stroke in proper book-engaging position.

By the described operations of the reaching-out contrivance a book or other object on the delivery support is reached-out for and slid inwardly from said support into the holder, which, as beforetated, is normally in line with the support, and the inmotion is continued until the book is brought mit the operations of the instrumentalities hereinafter to be described.'

The shaft X above referred to may be considered a secondary shaft, the main shaft X being preferably theY one to which power is applied for driving the mechanism ofthe present invention; andsaid shaft X may be considered as a single machine part taking the form of a shaft and having connections to the several instrumentalities referred to for the purpose of driving all of them in harmony with each other` or in the manner herein specilied. The shaft X may receive motion from shaft X through a bevel gear n2 on the latter engaging a bevel gear ze on the former.

Group swinging means.

There will now be described the means for swinging the holder E from the position in which it receivesfa book to the position in whiclrthe book is removed fromiit. Such swinging is substantially from the flatwise to an upright position, and such swinging correspondingly swings the book, enabling the latter to be then vertically moved from the holder into a vertically arranged clamp or the like. In employing the words vertical7 upright, etc., it is not done in an absolute sense, since approximate verticalness would obviously suliice, and in any case it is the f relative arrangement which is important. Fig. 2 shows the holder E in its substantially flatwise position in full lines, and in dotted lines swung to a substantiallyupright position, in which latter position in order to hold the book or signatures the holder is brought face to face with an upright retaining part G, said retaining part cooperating with the holder when the latter is first swung upwardly, and thereafter during the vertical movement .of the book out of engagement with the holder and into engagement. with a clamp. Said retaining part is preferably a fixed part and may constitute a portion of a frame member q which is extended downwardly and is secured to the base A at its lower portion and to the guide B at its upper portion. The retaining part or wall4 G is slotted at g2 and g, such slots being generally vertical, but their upper parts at least being inclined for a purpose that will hereinafterappear. The frame part g, ofl

which the retainin wall G constitutes a part, is of substantial construction, flanged where desirable, and it :forms therbase or support for' certain movable parts,` as will be hereinafter described.'

For swinging the holder Ean axle h may be employed, to which the holder E and its back plate ejfaresuitabl secured, and said. axle at one end is provi ed with an amhf arm' extendingv to where at its extremity it is pivoted to a link h2, which link at its other end is yoked at h3 and provided within said yokev with a roller h* bearing uponand actuated by a cam h5., mounted upon and rotating with the main shaft X; and said `roller and oke are guided through a swinging Il, pivoted at the upper end of a short standard hl and having an extension hs acted upon by a spring hg in` such manner as to tend to retain the roller h4 in contact with the cam h5. The cam h5 is of such contour as to cause first the up-swinging ofV the holder E, followed by a pause suiliciently long to permit the lremoval of the book followed by a down-swinging movement and a pause rsufficiently long to enable a new book'to be received on the holder,

Group lifting means.

The moving or lifting memberv which vertically shifts the book or 4other object j from the holder E to a clamp, may for con veniencey consist of a plurality of n'iembers such as the twin members J, J, each having an outwardly projecting stud j, and working in harmony so as to constitutev substantially a single contrivance. Eachyinember J in addition-to the projection 7' on which thebook rests edgewise, may comprise a slide j', said slide conveniently located to the inside of retaining wall Gr, and the projection j extending on the outside thereof beneath the holder E; there beinga connection between the slide and projection, such connection consisting of a pin jg extending through the slot g or g2 in the retaining wall, andan Aupright link j supporting the projection y at 'its upper end in such a way as to permit lateral play of the latter, so .that it may accommodate itself to the varying positions of the slot as the lifting member moves upwardly and downwardly. The upper end ofeach link 7'3 is provided with a follower j, projecting rearwardly into the slot g or g2 to compel the stud or projection j to conform in its `movements l with the shape of the slot.

To guide the lifter J in its4 upward and Adownward movements, slideways may be provided consisting for convenience of a pair of upright plates j, i4, secured on the inner side of thewall G, as seen in Fig. l, each plate j* being undercut to receive the correspondingly Aformed edges of the slide 'j'. Thus by sliding the slide jf upwardly and downwardly the studs j are carried up-y wardly and downwardly in a `corresponding manner and additionally are given lateral` movements according to the inclined portions of slots g', g. L

To actuate the slides j', jg, to movupwardly and downwardly a' link Tj may. bp, pivoted to the rear of each slide and extendbook.

lA pair of links j pivoted to intermediate portions of the respective levers j, j?, ex tend downwardly and are connected by .a

rod jl", to whiclrrod islconnected the lever ji", whose other end is pivoted at j to the central rib g3 of the frame part g. A pair of yopposed rollers jlz on lever jl bear upon a corresponding pair of cams `ila-mounted on the same shaft X that carries cam h5, said cams jl having such contour as to cause upward and downward movements of roller j with pauses between, so that the .lever j? and in consequence' the slides j', j',

will likewise move upwardly and down'- wardly with pauses at eachend of their stroke. 1

The same shaft X operating the mechanism just described and alsocausing the swing-y sok ing of the holder E, they will work in har mony, the cams being so timed' that after the holder has swung upwardly, the lifter then comes into play and from Fig. 2 Vit will be clearly seen that the studs j must push upwardly edgewise aga-inst the books and `force them from the space between holder E and wall G directly into the `openv clamp C, C', which is-the function ofthe lifter.

Group registering mea-ns. In order to cause the proper registry o r in a position beyond the holder E, and not requiring a corresponding slot. Now all of the slots g', g2, e, while generally vertical,

are inclined at leastat their upper ends, as

shown, andthe inclinations of all of the slots are the saine in position and extent. The result is that the studs j on nearing the end of their 11p-stroke and at a. time when the book is substantially in position within the clamp, are caused to be swung laterally or to the right in Figs. 1 and 3, tending to carry the book more than a sufficient distance in that direction to insure the contact of the book with the stem c of the clamp, said stem forn'iing a convenient stop for securing the proper adjustment of the ,Clamp closing means, For opening and closing the clamp C, C'.

to justify each book within the clamp, the 10Q the .following contrivance may conveniently be employed in cooperation .with the previously described instrumentalities: A part or bar K is of such shape and so located as to contactwith the inner ends of the spring encircled stems o, c', to which the movable clamp member C is secured. Bar K causes the opening of the clamp by pushing upon said stems and causes the closing by withdrawing to permit the springs c2 to'operate. The rod K is shown attachedl to the upper end of an arm. Ic, which actuates it to move to'ward and from the clamp, andV to steady the same the rod is is secured at the side of the bar opposite to the clamp extending to where it slides within a slideway/'or sleeve k2 pivoted between fixed frame parts .703, la. Arm lc is actuated from a shaft/7c* eX- tending parallel to shaft X; and said shaft Vk at another point on its length is provided with a second arm lc extending downwardly to where at its lower end is a roller le engaging and rolling upon the surface of a cam lc secured to shaft X. Said cam kis of a contour to cause the bar K to push the stems c, c', and thereby open the clamp, followed' by a pause, after which the clamp is permitted to close, followed by a second pause to give opportunity for another and empty clamp to be carried by the binding mechanism into position for receiving the succeeding signature-group.

Operation. The preferred operation of the above described arts will be as follows: Assum-l ing a signature-group to 'have been completed and advanced beyond the delivery end of the gatherin mechanism, and thus partially transferre and delivered on the x support D by the chain (l, and assuming an empty clamp to have been presented in the position shown, the action .of the transfer mechanism will. be the reaching out by the arm and linger F, f, engaging the book on the delivery support and drawing it inward until its rests upon the'swinging holder E, the book Z being seen in this position in Fig.

2. The holder then swings from the sublto stantially flatwise position shown to an upright position, its' flange e5 keeping the signatures in place and the opposed retaining wall G serving in cooperation with the holder E to keep each signature-group substantially upright. The .lifter J then comes linto play, its studs y" contacting directly against the lower edge of the signaturegroup, and 'as said lifter rises the group is orced upwardly between 'the'holder and retaining Wall, while the studs j are guided by the slots g, g2, in the ,retaining wall. The clamp C, CVhaving previouslyr been opened by the opener or bar K and said;-` clamp standing `upright' directly above the' bindin p the stem c ott' the clamp, such stein serving as a stop insuring the accurate positioning of the group. The clamp opener K then withdraws, causing the closing ot' the clamp by the action of the springs c'-. This substantially completes one cycle of operations, following which the lifter J and holder E return to their original positions prior to the transfer of a succeeding signaturegroup from the gatherer delivery to the next succeeding clamp of the binding mechanism.

The different cams referredto are so timed as to bring about the above described operations in the order named. A
