BOG!! BINDING AND OVBING MACHINE.

Application :Illed larok B1, 1927. serial Io. 177,189.

This invention relates'to an improvement in bookbindin and covering machines.

An object n this invention is to provide a suitable means for scoring the back of the e book transversel so as to enable it to re ceive and hold tlie lue or a suitable adhesive which is app ied thereto. Various means have been suggested and tried for this urpose, but for one reason or another, each as been more or less unsatisfactory.

This and other objects have been accomplished by the present invention which consists essentially in a spiral cutter which 1s driven in timed relation to the speed of the chain car ing the books through the machine so t at when once the teeth of the cutter engage the back ofthe book they move forward at the same speed as the books themselves.

This invention is an improvement of the book binding and covering machine shown and described in the dpatent to Bredenberg No. 1,073,324, ante September 16, 1913, and adapted to used in conjunction therewith.

The invention is fully described in the following specification and shown.in the accompanying drawings, in which:

Fi re 1 is a artia side elevation of the Bre enberg boo binding and covering machine showmg the cutter applied thereto;

Fig. 2 is a top (plan view of the same;

Fig. 3 is an en elevation of the same;

Fig. 4 is an enlarged end view of the cutter vartly in section;

1g. 5 is a combined longitudinal section and side elevation of the same;

Fig. 6 is a partial enlarged detail of the lolgitudinal bar for supporting the cutter; 1g

7 is a partial perspective of a bbok showmg the transverse cutters therein' Fig. 8 is a top lan view of a modified form of rotary cut r; and

Fig. 9 is a side elevation of the same. The embodiment illustrated is a book bindin and coverinor machine having a main ame 10 to willich is attached, by means not shown, two parallelchannels 11 and 12 having facing uide uWa s adapted to receive rollers 13 and, 14 whic are Journalled on suitable pins which serve to connect the links 15, 16, etc., of a continuous chain. The mechanism for driving this chain is fully illustrated and described in the patent to Bredenberg mentioned above.

These links carry lates 17 which are movably secured to the inks 15, 16 by means of pms18 which pass'through bosses 20 on the chain and are pressed toward the links means of springs 21 on the pins 18.

echamsm 'not shown herein, but fully shown and described in the patent to Bredenberg, presses the pins 18 outwardly against the action of the compression sprin 21 so that the signatures necessary to m e one book may be drop ed into the ace between the link 15 an the plate 1 after which the pms 18 are released and the spring 21 forces the plate 17 in until it grips the unbound book A. During this time, however, care is taken that the bottoms of these signatures lie uniformly in a horizontal plane.

The binding of these signatures into a book is accomplished b cuttin oil the folded backs as bg a knie or b t e rotary cutter 36 of the redenberg pa t, leaving the book a bundle of separate sheets. These are secured together b gluin the whole much as in ma in a g ued ta let. As the strength of the boo depends upon the bond between glue and leaves, book manufacturers have sometimes tried cuttin vnotches across the backs to strengthen t bond. After gluing the cover (not shown) is folded about the whole and pressed in glace, the glue serving to hold all these s eets and cover together.

Various schemes and means have been devised for cutting or scoring the .backs of O0 these signatures and the present invention employs a simple and e ective means for accomplishing this purpose and which at the same time scores all the pages to a uniform de th, the scoring at the same time lyin su stantially directly across the back of t e book.

This scoring mechanlsm consists essentially of a s l irai cutter B which is mounted upon a sha 22, the latter being journaled in suitable bearin 23, 24 which in turn are carried upon a roc er-shaft 25 which 1s journaled in bearings 26 which are adjustably mounted on brackets 27 by means of bolts assin through parallel slots 28 therein. hese grackets 27 are journaled upon a shaft 29 which is carried by a member 30, which is secured tothe main frame 10.

A lever arm 31 is'secured to the shaft 25 and has an adjustin screw 32 fastened to one end of the main rame so that by ralsing and lowering the yend of the lever arm 31, the spiral cutter B may be moved away froid and toward the unbound book A whichis to be scored. The rot-ary cutter is driven from the mam shaft 33 by means of the gear train 34, 35, the sprockets 36, 37, 38 and 39. Thus 1t will be seen that these gears and sprockets increase in speed continuously so that the rotative speed of the shaft 22 is much greater.

than that of the main shaft 33, because of this increase in speed it is difficult to start the book making machine with this gearattached. I have accordingly provided the shaft 22 with a pulley 40 which is driven by means of a friction-belt 41 from a motor 42.

Thus the motor 42, which is started at the y journalled in a bracket 58. A bevel gear 59 l 1s 'keyed on the shaft 57 and mesheswith a gear 60 keyed on a shaft 61'which'is suitably journalled in a bracket 62. The brackets 58 and 62 being carried by the main frame, the f. shaft 61 is driven by a sprocket 63 and chain I same time as the book binding machine starts the relatively high speed shaft 22 an thus relieves the main shaft 33 of the load of bringing these high speed shafts up to their normal speed. y

The rotary cutter' B is provided wlth atoothed helical blade or rather a 'series of blades 43 which will later be described in de tail. The pitch of these blades is such and the shaft22 is so geared to the mechanism which drives the c blades advance at the same rate as the booksA.

It will now be observed `that the axis of the shaft 22 is set at a slight angle to the path of the books A, this angle being substantially the angle made by the spiral blades so that the books cross these blades substantially at right angles to the blades at f the points of contact.. In this Wa the grooves C in the back of the book A 1g. 7 extend at right angles across the back.

lt will be obvious that the book A as 1t approaches the spiral cutter B is well to one side of the axis of the cutter and that'as it advances it crosses the axis of the cutter.

Thus, where the book A is of a considerable thickness, the cutter teeth'vvill first engage only the nearest leaves of the book, but as it advances more and more of the leaves will be brought into contact with the spiral blades 43 with the result that when the bock isdriven all the way across, the grooves C will be found to be out to a uniform depth throughout. s The depth of this cut is regnlated by means oi the adjusting screw 32.

The rotary cutter B is preferably madeup of end plates 44 mounted upon a tube' 45 and having a series of notches46 (Fig. 4)' which are adapted to receive the notched endso 47 of the parallel bars 48. These bars in turn are provided with notches 49 varranged therein in spiral form so as te resprung ain 15, thatv the .spiral Luanco I ceive the toothedhelical blades 43. These blades are preferabl steel or the like whic tempered. These blades are annular in form stamped from sheet and are severed at 43 (Fig. 4) and are so that the end of one blade is secured 1n alignment with the end of the next blade by means of plates 50 or the like which 1 i are secured in place vby means of bolts or rivets 51.

The bars 48 are provided with tapped.

holes 52 which are adapted to receive adjusting screws 53. After adjustment, the bars are securely locked by meansof set-screws This rotary cutter may be vmade in the l form of a single pitch thread l'or it may be made double or triple pitch if so desired.

In Figs. 8 and 9 is shown a modified form of rotary cutterin which the cutter or saw 55 is wound spirally and secured in a plate.

56 which is carried `by a shaft 57 which is is then hardened and 4 ip l 64 in tuned relation to the speed of the chain v I 15 in the same way as the shaft 22so that the books A will move forward at the same rate as the cutter blade 55. ln this way, the cutter blade cuts a succession of notches in the back of the book as shown in Fig. 7.

Thus it will be' seenfthat a very simple form of cutter is provided which has no rei ciprocating parts and which will automatically keep in step with the advancing book f y geared to the mechanisml since it is positively which drives the'chain 15.

After the 'book passes thecutter,iglue is spread upon the'back by mechanism similar to that shown in the previously mentioned patent to Bredenberg afterwhichja cover is secured thereon in a well known manner.

While I have' shown and described butl a single embodiment of this invention, it is 'unbound books at intervals and hold them Vwith their back edges in alignment, and

tverse cutting means traveling at the same speed as the book `for cutting a series oi notches in the back @edges of said book it advances. I
