Appiieation fue@ April 25, 1911. serial No. 623,315.

To all whom it may concern.'

Be it known that I, ALFRED BREDENBERG, a citizen of the United States, and a resident of Champlain, Clinton county, New York, have invented ceitain new and useful Improvements in Bookbinding-Machines, .of which the following is a specification.

The present invention relates inoie especially to book-binding machines and involves a transferring mechanism adapted to assist or render automatic certain operations of such binding machines; although the in- 1 veiition might be equally useful in various other kinds of machines.'

The invention has for an object to provide a means for successively transferring a series of objects, such as signature-groups,

^ from the delivery of a gathering mechanism into justified position within a series of clamps, for such binding or other operations as are to be performed upon the same; the gathering and binding mechanisms heilig thus operatively associated into a single book making machine; and other and more specific objects will appear hereinafter inthe following description or Will be obvious therefrom. The term sigiiature-gro-iip shall be used herein in al representative sense as including any analogous object consisting of assembled components designed finally to constitute a book or analogo-us article.

The invention consists in the novel parts, constructions, contrivances and combinations hereinafter sliown or described.

The accompanying drawings referred to inthe following description and foiniing a part hereof, illustrate one embodiment of the present invention, the same seiving in connect-ion with the description to explain the principles of the invention.

ln the drawings, Figure 1 is a front elevation` partly in section of parts of a book binding machine, including a transferring mechanism embodying the present improvements. Fig. 9. is a right-hand elevation partly in section taken substantially on the plane 2-2 of Fig. 1. Fig. 8 is a plan view of the mechanism seen-in Figs. 1 and 2. Fig. 4 is a front detail view of one of the coiitrivances shown in Figs. l, 2 and 3; Fig. 5 being a similar view of the same in a different stage of operation; and Fig. 6 being a right-hand view thereof.

The .present invention involves a book binding machine including 1n combination a signature gathering mechanism, a bindinggathering mechanism to the position (upright) in which it is moved into the clamp.

yThe term clamp is used in a sense to include equivalents.

More specifically looked at the invention includes the following features:

The transferring mechanism hereof comprises a distinct part which may be termed a holding member or holder, which is adapted to have the objects (signature-groups) fed into it one at a t-ime, combined with a moving member for moving or lifting each successive object from the holder into engagement with a clamp or the like.

According to another feature of the invention the holder is of such character as to receive each successive signature-group or lother objectflatwise and thereafter swing or tip upward into substantially upright position preparatory to a vertical (preferably ascending) movement of the object into a clamp or the like.

According to still another feature a mov- =ing or lifting member is contemplated which engages with the object inthe holder and moves bodily from the holder (upwardly or downwardly) toward the clamp, carrying the object thereto. According to still another feature is contemplated a. contrivance for shifting the olojects to the holder, comprising an arm or finger which reaches out for each successive object and draws it into pro-per position in lthe 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 to open and close a -clamp in harmony with the operations of the other parts of the mechanism.

As further features of the present invendicated as the object handled by t tion are justifying or registering stops serving to insure the accurate positioning of each objectl so that when it has been engaged inl the clamp for any desired subsequent operations, it will occupy the precise necesment that is illustrated in the drawings hereof, in'which a signature-grou Z is iniie mechanism. Some of the main portions of the machine, as to which per se no claim of novelty is herein directed, will first be described, and thereafter the novel mechanism illustrating the present invention will be set forth.' The machine has a frame A carried on a base A, and certain specific frame parts that coperate with the transferring mechanism will be hereinafter described in connection with the latter. .In the upper part of the frame is an upper guide B and lower guide B 'shown in the form of channels adapted to receive between them and guide carriers of any known design comprising clamps C, C', intended to hold a book, signature-group or other object to be treated. The said guides and carrier constitute a convenient and well-known means of successively presenting a series of signature-groups to the various instrumentalities comprised in a book binding machine; and for convenience there may be an extended series o-f carriers connected in a train and intended to move intermittently along the guides B, B', which lnay take the form of an endless track, as clearly seen in Fig. 3, so that each carrier or clamp on completing a cycle of operations will stand at position ready to repeat. The

guide is indicated in Fig. 3 as having a.

straight st-retch o-n either side of the machine and a curved connecting portion at either end. The arrow?) indicates the direction of travel of the carriers; and several carriers are indicated in dotted lines in addition to the one which is in cooperation with the transferring mechanism forming the particular subject of this invention. Thus C2 indicates a carrier-whose clamp has been opened to release a book that has completed its treatment; C3 and C4 indicate the succeeding positions in which the clamp has closed; The clamp C, C', shown in cop-.

eration with the present invention is indicated in open position. Vhen'a clamp has l been opened it is preferably closed by means of springs sufficiently powerful to hold the object firmly within 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 0, c which extend through apertures in the innerA 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. Atthe inner ends of stems c, 0 are heads c3, c3 adapted to be pressed upon by a means which will be hereinafter described, for the purpose of sliding the stems outwardly and opening up the clamp against the resistance of the springs o2 which subsequently close the clamp.

Portions of a gathering machine or mechanism are shown as illustrative of various mechanisms in conjunction with which the presentI invention might be employed, and such gathering mechanism will not be described in full detail as it. is the subjectof protection and description in another application filed by me April 28, 1911, Serial No. 623,872. 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'assembling books are caused to travel. Such a support D is indicated in Fig. 1, it being slotted and having a traveling chain or sprocket (Z projecting through such slot so as to stand above the support surface. The sprocket chain Z passes around a sprocket wheel Z2 mounted on a shaft which has another sprocket wheel engaged by a second sprocket chain Z3 which in turn engages sprocket wheel (Z4 mounted on the same shaft X as the bevel gear wheel hereinafter to be referred to, from which the sprocket chain (l obtains its motion. A flange (Z5 along the lower edge of the inclined .carrier or support D is contacted by each assembled book and keeps the same from falling from the support. Each pin (Z on reaching the sprocket wheel (Z2 passes downwardly out of the slot, and the accumulated signatures or assembled book in fro-nt of such pin is thereby delivered at the left end of the support D, which left end may therefore be designated a delivery support D.

Portions of the mechanism to which the present improvements more particularly redelivery support D before referred to, that is, so as to hold the assembled signatures substantially flat-wise; and 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 which is only incidental to the present invention, and insufficient in extent to change its character from what it would be if normally strictly horizont-al. 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 a 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 left edge with a flange or stop e3 preventing over travel of the object and serving to adjust it into 'proper registration for further action upon it. The holder E has a back plate or support e4 whose tting will be hereinafter described. At the inner lower edge of the holder is indicated a flange or stop e5 preventing the objects sliding off the inclined holder, and flange being in line with and forming substantially a continuation of flange d5 of the delivery support D.

' Havingthus identified the holder E, reference will now be made in order to thefollowing, namely: a cont-rivance which serves to reach out to the delivery support and draw each object upon the holder; a means of effecting certain movements of the holder E for cooperation with the means hereinafter in this paragraph mentioned; a means Ifor moving each object from the holder E into an open clamp; 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 o f a clamp in harmony with the other instrumentalities.

. The reaching out contrivance comprises a swinging arm F carrying a hand F on which is a nger f, these parts so located that the nger 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 f'which is fixed to the frame of the machine as indicated in dotted lines j in Figg, and is incapable" of rotation. The hand F is pivoted at f4 to the arms upper end so as'to be able to swing to a slight extent to permit the finger f to 'be moved out of and into the slot of the delivery support.

To swing the arm F may be employed a link f5 connected at one end to such arm and at the other end to a lever f6 turning about a fixed pivot 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 f6 is provided with a roller f adapted to engage the surface of a cam flo mounted upon a shaft X. By the rotation 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 finger f are controlled as follows. Mounted on the xed stud f3 and capable of turning thereon, is a sleeve f which is provided with a tightening device f by which any desired amount of friction between the sleeve and the shaft may be secured. The friction sleeve is held 'in place on the stud by two collars f2", f2 on outst-roke to swing downwardly out of such position. The connections between friction sleeve fu and the finger f comprise an arm fw secured to the sleeve f and having pivoted to its extremity a short link f whose other end is connected to one arm f15 of a two-arm lever in the nature of a bell crank, having a rotating stud f1 projecting from arm F, and whose other arm f in turn has pivoted to it a long link fm extending upwardly to where it is adjustably pivoted at f1.9 to the hand F that carries at its extremity the finger Fig. 4 represents the parts as having just reached the .end of the instroke, and they are about to return out- Wardly o-r to the right.` The friction of sleeve fn temporarily renders it substantially stationary with stud f3 so that through link f the movement Vto the right of arm F effects a slight oscillation of the bell crank fw, f, and a pulling down of the link f18 and consequently a lowering of the finger f out of the slot of thedelivery support. A stop f22 on arm F limits the bell cranks rotation in this direction, its rotation in the opposite direction being limited in a manner that will hereinafter appear. The swing'ofthe bell crank is insufficient to permit the friction sleeve and arm fla to remain stationary throughout the entire swing of arm F, and consequently at a certaln point the sleeve f commences to overcome reaching its book-engaging position. The finger f is not formed directly on the hand F but as seen in Fig. 6 is substantially offset therefrom, the hand and finger being connected by a roller f2s; this arrangementpermitting the finger to enter the slot of the delivery support, but preventing the hand from entering it, and the roller f2s serves as a stop coming into contact with the edge of the slottedsupport or a track f thereunder, and preventing the finger rising above the position seen in full lines in Fig. 4 and in dotted lines in Fig. 5. As soon as the roller f23 has been lifted with the finger sufficiently to contact the delivery support, the friction sleeve as before commences to revolve with respect to the stud f3. On the instroke the roller f23 will slide along immediately ybeneath the delivery support and maintain the finger f throughout suchstroke 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 before stated is normally in line with the support, and the inmotion is continued until the book is brought into contact with the stop e3 of the holder, at which time the book is in position to permit the operations of the instrumentalities hereinafter to be described.

The shaft X above referred vto may be considered a secondary shaft, the main shaft X being preferably the one to which power is applied for driving the mechanism of the present invention; and said 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 specified. The shaft X may receive motion from shaft X through a bevel gear :u on the latter engaging a bevel gear on the former.

There will now be described the means for swinging the holder E from the position in which it receives a book to the position in which the book is removed from it. Such swinging is substantially from the fiatwise to an upright positionl and such swinging correspondingly swings the book, enabling thc latter to be then vertically moved from the holder into a vertically arranged clamp or the like. In employing the words vertical, upright, etc., it is not done in an absolute sense, since approximate verticalness would obviously suffice and in any case it.

is the relative arrangement which is important. Fig. 2 shows the holder E in its substantially fiatwise position in full lines, and in dotted lines swung to a substantially upright 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 coperatmg withthe 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 g 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 wall 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 hereinafter appear. The frame part g of which the retaining wall G constitutes a part, is of substantial construction, flanged where desirable, and it forms the base or support for certain movable parts as willbe hereinafter described.

For 'swinging the holder E an axle z, may be employed, to which the holder E and its back plate e4 are suitably secured, and said axle at one end is provided with an arm h extending 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 yoke with a roller h4 bearing upon and actuated by a cam h5 mounted upon and rotating with the main shaft X; and said roller and yoke being guided through a swinging arm h6 pivoted at the upper end of a short f standard if and having an extension 71,8 acted upon by a spring it in such manner as to tend to retain the roller h4 in contact with the cam 71,5. The cam z is of such contour as to cause first the up-swinging of the holder E, followed by a pause sufficiently long to permit the removal of the book, followed by a down-swinging movement and a pause sufficiently long to enable a new book to be received on the holder.

The moving or lifting member which vertically shifts the book or other object from the holder E to a clamp, may for convenience consist of a plurality of members such as the twin members J, J, each having an outwardly projecting stud j, and working in harmony so as to constitute substantially a single contrivance. Each member J in addition to the projection j on which the book rests edgewise, may comprise a slide j', said slide conveniently located to the inside of'retaining wall G, and the projection y' extending on the outside thereof beneath 4the holder` E; there being a connection between the slide and projection, such connection consisting of a pin y'2 extending through the slot g or g2 in the retaining wall, and an upright link ja supporting the projection 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 50 tween holder E land wall G directly into the -correspondingly formed edges of the slide j. Thus by sliding the slide j upwardly and downwardly the studs y' are carried upwardly and downwardly in a corresponding manner and additionally are given lateral movements according to the inclined por? tions of slots g', g2.

To actuate the slides j', j2 to move upwardly and downwardly a link j may be pivoted to the rear of each slide and extended to where at its other end it is pivoted within the yoked end je' of a long lever j?, there being two identical levers j? as seen in Fig. 8, and each having its far end pivoted at js to a fixed part of the machine. A pair of links j pivotedw to intermediate portions of the respective levers j?, j?, extend downwardly and are connected by a rod j, to which rod is connected the lever jl", whose other end is pivoted at j to the central rib g3 of the frame part g. A pair of opposed rollers'j12 on lever jl" bear upon a corresponding pair of cams jm mounted on the same shaft X that carries cam h5, said cams j having such contour as to cause upward and downward movements of roller l7'12 with pauses between so that the lever j? and in consequence the slides j', y", will likewise move upwardly and downwardly with pauses at each end of their stroke.

The same shaft X operating the mechanism just described and also causing the swinging of the holder E, they will work in harmony, the' cams being so timed that 5 afterthe holder` has swung upwardly, the lifter then comes into play and from Fig.

2 it will be clearly seen that the studs j must push upwardly edgewise against the books and force them from thespace beopen clamps C, C', which is the function of the lifter.

following mechanism may conveniently be employed. Reference has already been made to slots g, g2 in the retaining wall G, and to thefact that a follower j connected to the stud y' engages such slots. It has also i been made to appear that the holder E has a"slot e, this receiving the outer extremity of one of the studs j, the other stud j being in va position beyond the holder E and not requiring a corresponding slot. Now all of the slots g', g2, e, while generallyvertical, are inclined at least at their upper ends as shown, and the inclinations of all of the slots are the same in position and extent. The result is that the studs y' on nearing the end of their upstroke 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. l and 3 tending to carry the book more than a sufiicient distance in that direction to insure the contact of the book with the stem c of the clamp', said stem forming a convenient stop for securing the proper adjustment of the book.

For opening and closing the clamp C, C, the following contrivance mayconveniently be employed in coperation with the previously described instrumentalities: A part or bar K is of such shape and so located as to contact with the inner ends of the spring encircled stems c, 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 attached to the upper end of an arm k which actuates it to move toward and from the clamp, and to steady the same the rod lc is secured at the side of the bar opposite to the clamp extending to -where it slides within slide-way or sleeve 7a2 pivoted between fixed frame parts 7c3, k3. Arm 7c is actuated from a shaft 7c* extending parallel to shaft X; and said shaft if* at another point on its length is provided with a second arm h5 extending downwardly to where at its lower end is a roller lo@ engaging and rolling upon the surface of a cam la" secured to'shaft X.. Said cam 7N is of a conf tour to cause the bar K to push the stems c, c and thereby open the clamprfollowedby a pause, after which the clamp is permitted to close, followed by a second pause to give opportunity for another and empty clamp to j be carried by the binding mechanism into position for receiving the succeeding signature-group.

The preferred operation of the above described parts will be as follows: Assuming a signature group to have been delivered on the support D by the gathering mechanism and assuming an empty clamp to have been presented in the position sho-wn7 the first action of the transfer mechanism willbe the reaching out by the arm and finger F, f, engaging the book on thedelivery support and drawing it inward until it rests upon the swinging holder E, the book Z 'being seen infthis position in Fig. 2. Theholder then swings from the vsubstantially atwise position shown to an upright position, its flange e5 keeping the signatures in lplace and the opposed retaining wall G serv-ing in cooperation with the holder E to keep each ceeding clanip lifter J then comes into play, its studs j contacting directly against the lower edge of the signature-group, and as said lifter rises the group is forced upwardly between holder and retaining wall, while the studs j are guided by the slots g', g2 in the retaining wall. The clamp C, C having previously been opened by the opener or bar K and said clamp standing upright directly above the space between the holder and retaining wall, the group is thereby caused to pass directly into the clamp between its walls C, C; and the upward movement is continued until the group reaches the proper predetermined height. During `the rise of the group the studs j engaging the inclined portions of slots g", g2, are caused to move laterally, swinging about their links js and thereby bodily carrying the group of signatures laterally or edgewise toward the right, Fig. l, until said group comes in `contact with the ystem c of the clampsuch stem serving as a stop insuring the accurate positioning of the group. The clamp opener K then withdraws causing the closing of the clamp by the action of the springs 02. This substan-` tially completes one cycle of operations, following which the lifter J and holder E return to their original posit-ions prior to the transfer of a succeeding signature-group from the gatherer delivery to the neXt sucy of the binding mechanism. The different cams referred to are so timed as tobring about the above described operations in the order named.

It will be seen that by' reason of the construction above shown land described, a transfer mechanism is provided which answers the objects and affords the aditantages of the invention as hereinbefore set forth; and other advantages will be appar-v ent to those skilled in the art.

It is to be understood that the invention in its broader aspects is not limitedto the precise construction shown nor to any particular construction by which the invention -has been or may be carried into effect since many changes may be made in the details of the parts without departing from'the main principles of the invention and without sacrificing its chief advantages.
