Patented Dec. 16,Y 1930 CHARLES C. HOWARD, OF LOUISVILLE, KENTUCKY MEANS Eon AssEMBLING SHEETS ANDArPLYiNG ADHESIVE THEEETO Original application filed November 2.2, 1'928, Serial No. 321,216. Divided and this application filed September 20, 1929.

This application is a division of an application filed' by me November 22, 1928, Serial No. 321,216.

have heretofore producedl a book in which the several sheets or leaves are bound together in such a manner as to produce a book which will open flat, and in said book the several leaves are formed with tongues along their binding edges with the tongues of the in alternate leaves relatively staggered so that the application of adhesive across thefree ends of the tongues will cause the tongues on alternate leaves to be attached, relative transverse shifting of the leaves being prevented is by the tongues on one leaf passing through the spaces between the tongues on an adjacent leaf.V rIhe present invention provides means whereby the prepared leaves may be expeditiously assembled, receive adhesive and be rlhe invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being particularly pointed out in the appended claims.`

lu the operation of the machine shown in Figure 1, the sheetsI or leaves 1 are carried over a feed table 4 to. a cutting mechanism at 5V bythe action of which notches are cutin the advancing or forward edges of the sheets is a section on the line 5 5V of Vsection .on the line G-Sof Serial No. 394,006.

to form tongues 2, the tongues on the alternate sheets being staggered as will be understood by reference to Figure 8. From the cutting` mechanism, the leaves pass to folding mechanism at 6 where folds 3 are formed across the free ends of the tongues, the leaves being-presented to the folding elements in pairs so that the tongues on one leaf will be entered in the notches in the companion leaf. From the folding mechanism, the leaves are delivered through a guide to a pair of rollers 153 which rcrease or flatten the folds and feed the leaves to the assembling and glue-applying devices.

All the workingparts are driven by a motor 7, a belt 78 being trainedabout a pulley 17 on the motor shaft and a pulley 79 secured on a shaft 77 which is mounted on the lower portion of the frame of the machine.

The rollers 153V deliver the sheets onto feed belts 154 which are mounted upon suitable rollers or pulleys 15,5' and, in turn, deliver the sheets onto a table 156 which is so arranged that it will move downwardly as the number of sheet-s delivered thereto increases and will present the treated sheets to an open lower part of the supporting frame through which they may be withdrawn. This table is constructed with a reinforcing frame 157 on its under side and at the lower end of said reinforcing frame are guides 158 which slidably engage standards 159 forming4 part lof the supporting frame of the machine so that the'table will be guided and maintained in a stable condition in its movements. At the upper ends of the standards 159 is journaled `a shaft 160V`and uponsaid shaft at the ends ofthe same are secured sprockets 161 having chains 162 trained over the saine. Each chain has one end'attached to the platform 156 or its reinforcing'frame while the other end of the chain carries a weight 163, the weights counter-balancing the table and resisting downward movement of the same'so that it can only rnove downwardly at a rate correspending to the rate of increase of the weight of' the paper imposed thereon. TheV shaft 160 is also` equipped. with a ratchet wheel 164 and a pawl 165 is mounted upon the adjacent Standard 159 to engage said ratchet wheel. so

ceV

that, when the pawl is in active position, the shaft cannot be rotated under the influence of the weights 163. At one end of the shaft is also provided a hand wheel 166 whereby the shaft may be rotated to raise the table when a book has been removed therefrom and it is to be placed in position to receive the sheets for a second book. Slidably engaged with the upper portions of the standards 159 are runners or brackets 167 from which braces or hangers 168 depend to carry a frame 169 which extends across the width of the machine and has secured to its undeil side parallel longitudinally extending, presser bars 170 which project forwardly to points immediately adjacent the feed rollers 153 so that sheets carried from said rollers by the belts 154 will be caused to pass under the presser bars 170. The frame 169 is reciproated vertically by pitmen 171 pivoted at their upper ends to the ends of the frame and at their lower ends to crank disks 172 carried by a transverse shaft 17 3. The presser bars 170 are thereby alternately lifted so as to permit the passage of sheets thereunder and then brought down so as to bear upon the sheets and hold them in position to receive the `glue. Guide rails 174 are secured to the under side of the frame 169 and project rearwardly therefrom parallel with the presser bars 170 and in lateral relation thereto, and the front ends of these guide rails are curved outwardly so that the sheets will be readily Q.uided into the space between the rails, These rails are spaced apart a distance equal to the width of the sheets so that the sheets will be properly alined and in order that the sheets may be engaged by these rails and alined, even though they should be presented to the rails somewhat out of alinement, the rails are secured adjustably to a transverse reciprocatory bar 175 which is slidably mounted in bearings at the ends of the frame 169, a bar 175 being` provided at each end aortion of the frame and the inner ends of the bars being fitted within a coupling sleeve 176 which houses a spring' 177 tendina` to press the bars apart. The outer ends of the hars 175 are adapted to bear against the beveled upper ends of stationary cams 178 which are vertically adjustable upon stationary parts of the supportingframe so that as the frame. 169 is moved downwardly the bars 175 will be shifted laterally and the `uide rails or jonger plates 174 will be moved inwardly to properly center the sheets. Slidably mounted upon side members of the main supporting frame are bearings 179 carrying' a rock shaft 180 which extends across the fra-me above the feed belts 154 and the presser bars 170 as well as the jogger and guide rails 174. At points adjacent the presser bars and between the feeder belts, jogger arms 181 are secured to this shaft and project therefrom in such position that when the shaft is rocked these arms will impact against the rear ends of the sheets and will cause the same to be presented evenly to the glue-applying elements. The shaft 180 is reciprocated upon the frame members 182 through means which will be presently described and adjacent the bearings 179 has tappets 183 secured thereon, the tappets being` normally in an upstanding position. Secured to the frame bars 182 at the rear of the'shaft and its bearings are abutments 184 which are alined with the tappets 183 so that if the shaft be drawn rearwardly the tappets will be caused to impinge against the front ends of these abutments and thereby rocked, the shaft being consequently rocked in its bearings so that the j ogger arms 181 will be swung against the ends of the sheets. The bearings 179, as shown most clearly in Figure 6, are constructed with guide feet 185 on their under sides which slidably engage the frame members 182 and are constructed with toes 186 engaging in grooves formed in the sides of the frame members whereby the bearings will be held in place. r1`he shaft 180 is loose in the bearings 179 and secured upon the shaft at the ends thereof are brackets or blocks 187, in the lower ends of which are secured the front ends of pusher rods 188, said pusher rods extending' rearwardly and havingV their rear ends secured in eyes 189 carried by the lower ends of angle levers 190 'which are pivotally mounted upon the rearmost standards 191 of the main supporting frame. Normally these angle levers are in the position shown in Figures 1 and 2 and the shaft 180 is spaced forwardly from the abutments 84, then the angle levers 190, however, are rocked rearwardly, the rods 188 pull the shaft rearwardly so that t-he tappets 183 are caused to impinge against the abutments 184. and rock the shaft. As the return movement of the shaft 18() carries the tappets from the abut ments, the shaft is rocked in the opposite direction and the tappets again set in upright position by a torsion spring 380 coiled about the shaft with one end fixed thereto and its opposite end fixed to the adjacent bearings, as shown clearly in Figure 4.

It will be noted upon reference to Figures 1 and 2 that the forward edges of the angle levers 190 are of an ogee shape and that the long arms of the angle levers project appreciably forwardly from the standards 191, a spring 192 attached to the frame at one end and having its opposite end engaged with the respective angle lever yieldably holding it in the position shown. Slidably mounted upon each standard 191 is a block 193 in which is journaled a shaft 194 carrying the glue-applying knife 195 and equipped with rollers 196 each adapted to engage and ride on one of the angle levers 190. It will be seen naeaeei that, .when the block. 193 ismoueddownwardly, theirolleri` 19.6,.acting onA the. forward edge ofthe angle leve.1r190:wiljl; swing saidY lever rearwardly so that the shaft .will be drawn rearwardly and the described action accomplished. The glue knife 19,5 comprises a framesecured to the shaft 194 and extend` ing `longitudinally thereof, and a; blade properv 19:7" secured longitudinally to Vthe fname and: adapted in. one` position to engage the gluefcarrying belt 193 and in another position toA apply the glue. or other adhesive to the tongues of the sheets upon the table 156. .The pivotv of the angle lever is fitted in a block 199 which is secured to the adjacent standard 1911 and projects to the inner side thereof where it is formed into or provided with a rack 200 in the vertical plane'of a pinion 201 securedv upon Ythe shaft 19d! so` that as the shaft isvmoved vertically the pinion will be causedV to ride over the rack in mesh therewith and consequently, rock the shaft sol that the knife will be reversed. The. knife frame has extensions g 202 at its ends which at the respective; limits of movement are engaged in keepers 203` and 204` respeotivelywhereby the knife is caused to move in a true vertical plane in applying `the glue: to' the sheets` `orreceiving the glue frointhesupplying belt 198, Vertical movement is imparted to the knife shaft by pitmen 2051' having their upper ends pivotally mounted upon the ends of the shaft and,` their lower cnds attachedto cranksfor levers 206 which are secured to the end sl ofa transverse sh-at 207, sai'dj shaft l2077 having secured thereon a gear=208which meshes with a gear 209 onthe shaft 1733'. `The shaft 173 is .drivenby a chai-n 2110 train-edaround a sprocket onv saidl shaft and around? a sprocket on anV intermediate shaft-,which receives motion` through a belt from the shaft 77.A

Above the shaft' 1911, a transverse beam 212 isl secured upon the main supporting framel and projects laterally to oney side of the same, andi" the; glue pot or tank` 213' is suspended froml this beam byhangers 214. The glue-carrying belt 198r "passes over` a transfer rol=ler2-15 in the and is trained about Apulley-s or guide rollers 216' at the opposite ends of the beam. rlfhe guide ml-ley or roller 216 more remote from thel glue tank has its arg-le or shaft 217 extended* rearwardly and' upon therear end thereof is secured a friction pulleyf218 which normally enigagement with a friction pinion 219'" onl the shaft of a small motor 220,A this motor driving the glue-conveying belt but performing no other work. The motor 2,240 is carried by a shelf 221 which is secured to and rojects rearwardly? fromI a beam disposeA above and' at the 'rear-g of the beam 2112 and pivotally attached at its end more remotefrom-` the motor to the adjacent standard 19:1 while at its shelficarry-ing end it isv equipped withl a away. fromI the standard Carried by the sliding block 193 whichl is below the shelf 221 is a pusherv bar 225 which extends upwardly from said block and is arranged to impingeagainst an; abutment screw 226 mounted through the beam 222v so that, when the knife is raised. to. engage. the glue belt and take glue therefrom'lthe motor will be shifted; soithat the pinion 219: will be out of engagement with the pulley 218A and the belt will remainI at rest.

Carried by the standards 19.1 is a back stop 227 against which the sheets or leaves are caused to, abut by the action of the jpg ger arms 181. As shown most clearly in Figure 2, the keepers 203. and 204 are brack ets or plates secured' to. and projecting for#y wardly' from the standards 19:1 and having theirv front ends provided with flanges 228 which are turned inwardly and may be eX-V tended and turned forwardly. Said flanges are located in spaced: relationito thestandards so that theext'endedr ends of the knives will be caused to ride within the keepers and be guided. intoA proper engagement with the. glue belt or with the stacked sheets accordingly as the knife is at the upper or lower limit of its movement,

The feed.' belts 154i are'carried by drums or rollers 1155, the bearings for the forward drum or roller being mounted upon frame members 231 rising from the frame bars 8-1 and said members 231 carry frames: 232; in which the rollers 153 are mounted, while the shaft 233. carrying the rear `rollers. 155i is supported in arms 2341l secured tothe main sup.- porting frame and having a rack or plurality of notches 235: in its upper edge so, thatY by setting the shaft in selected notches the tension of the feedE belts.I may. be maintained. Thel shaft 2316 carrying the forward rollers or drums isequipped witll .a'pinion 237'meshwhich is mounted upon the frame between the. rolilers 153T and the folders. so: that, when theshaft 23,9 is` rotated, the feed belts 154: will be drivenin the proper direction. A sprocket pini-on 240lis secured upon: the shaft 239 and a` chain. 2111i train-ed about said pinionand about a pinion on the shaft 77 so that the gearing just described will be. driven fromV the last named: shaft.

It is. thought that the operationy ofthe apparatus wiilil be understood from: what has been said but it mayl be briefly summarized. The blank sheets or leaves are fed vin any convenient mannerv onto the initial feed'` belts which carry them to the cuttersand the cutters make notches in theV advancing ends of the sheets., the cutters and cooperating elements being manipulated so that theV tongues anldnotches in successive sheets will*V be "staggered".l The outY sheets are then carried t'o ing with. a gear'238:sec1,1red upon a shalt239 the folder mechanism and two sheets have the free ends or tips of their tongues folded and simultaneously with the folding action are caused to advance somewhat toward the glueapplying devices. The folds are flattened by the rollers which also feed the sheets onto the table 15G or the sheets already deposited on the table and the table gradually descends as the sheets are piled thereon, pressure to start the sheets downwardly being applied through the presser bars 170, and simultaneously with the engagement of the sheets by the presser bars 170 the glue knife is brought into contact with the sheets to apply glue to the upper surfaces of the folded tongues at the ends thereof. Each successive pair of sheets will be thereby pressed onto the sheet below it by the knife and the presser bars so that the tongues on alternate sheets will be joined together by the glue or other adhesive, and when a sufficient number of the sheets or leaves have been treated with the adhesive they are withdrawn from the table through the space between the standards 191 below the back stop 227 for the application of the backs and sides of the book cover. The apparatus operates very rapidly and produces a complete book ready to receive the cover very economically. No sewing of the books is necessary and while the leaves or sheets are joined only at their extreme ends they are very securely held together and the bound book will open flat and lie flat at any point.
