Specification of Lett-ers Patent.

Patented July 23, 19t?.

Application filed July 26, 1909. Serial No. 509,5?2.

the provision of a single machine wherebyV the covers will not only be secured tothe back of the book or pamphlet but also to the sides for v'a predetermined distance, thereby providing the book or pamphlet with a cover more lirmly secured in place than is the case .with themethod 'or machines at present in use, and at the same'v time having the covers take over the stitches or staples employed to bind the book or pamphlet, thus producing a very much neater appearing book or pamphlet.

A further object of the invention `is to provide a machine that will not only be automatic in its operation'and will permit of its adaptation to books or pamphlets of varying sizes; but will be continuous in its operation, thereby giving it greater capacity than that of the machines now employed, which operate intermittently g4 furthermore, my improved machine does not possess the serious objections found in the intermittent type o-f machines at present employed towit the jar and vibration caused by the frequentl start-ing and stopping of such type of machine` which is not only a Wear and tear on' the machine itself but also on the structure u in which it is located, also creating consid- 40 crable noise. The advantages of my invention will more l fully appear from the detailed description taken on -the line i-Lt of Fig.v 1 looking toward-theleft. Fig. 5 is a similar view taken on the-line 5-5 of Figl` l looking toward the left or feed-hopper 'end vof the machine.

Fig, `6 arerdetail views of adjusting mecli anism to provide for variations in the thick A i ness of books passing through the machine.

Fig. 7' is a detail in perspective to illustrate one method of stacking or shifting the covered books delivered vfrom the machine.

F ig. 8 is a detail view ofthe gripping and sheet-lifting mechanism. Fig.l 9 is a' detailview m perspective vof the detector or sheetlift controlling mechanism' shown at one end of the @over applyngcylrnder.- f-

The machine comprises any suitable frame upon which is supported the feed-box or hopper A, which is preferably. mounted above the bed-plate or top of the machine.

This hopper contains the unbound books or f pamphlets to be covered, which are vto be fed from the bottom by'A means of a beltfei` belts @,Which are provided. at predetermined points With lugs or projections a. The belt a, takes about rollers or pulleys b; the one roller, for examplevroller b, receiving power by means of a pulley. or belt, chain or otherx suitable mechanism, from drive-shaft` B, Which shaftin turn driven by belt from the power-shaft. Drive-'shaft B may be used to supply power tothe different partsl Thebound books are placed in the'.

of the machine m any of the well known ways; hopper or feed-box A with their backs or bound edges' presented in the direction fof travel 'of belt a, 'so' that as lug or project-ion a catches or takes against the lowest book, it Will be carried by belt or chainel beneath roller 0. and dropped down between guides (l, cl, ont-o the bed or book race-plate C (see Fig. 5), Where it passes between. rollers e, e, which may be driven in any suitable manner as for example by sprocket-chains fv Which take about sprocket wheels g, g, either oneor both of said wheels being` driven invany suitable manner. The rollers e, e may be mounted as shown in Figs.` 5 and 6 with ltheir ends held by the pillows or blocks c A cw; the position of the latter being controlled by the screws et and e5 which take through the frame of the `machine and into or against the pillows. e'e. In addition to the action of the rollers to carry the books or pamphlets forward along the bed or rapeplate, the chainsv f may also be provided with small lugs or lingers 1y f', varranged on the chainsr vat predetermined points, to takeagainst the rear edge of the book and compel it-s positive travel.

may be so arranged. as` to permit of their l ready adjustment at any point on the chain so as to accommodate books or pamphlets of dilferent lengths. rlhe books are held between the chain and rollers and fed along until they have. received the cover, when they willl be held between the blades or guiderods L, It', and angularly arranged rollers until they reach the packer or receiving tray D, at the end of the machine, see Fig. l. As

lthe book travels along between the rollers e,

and the chain f, its sides near the back-edge come between the small horizontally arranged rollers i', which take against the gluesupplying disks or wheels E, E, which are suitably mounted and revolve in the glue` Or paste boX E mounted beneath the bed or book-race plate C; the glue or paste box F/ may be of any suitable construction (see Figs. l and 5).

The disks or wheels E, E, are suitably mounted on a shaft F, which may be driven in any well known manner as for example by providing shaft F with bevel gear F meshing with bevel-gear G, mounted on the driveshaft B, (see Figs. 2 and 5). Rollers i.

are of a thicknessto correspond with the desired extent to which the covers are to be secured to the sides of the book; this extent preferably being'just suflicient. to cover the staples or stitches whereby the book is bound. The books or pamphlets continue traveling during this operation and are then brought with their backs into contact with glue or paste-applying wheel or disk H, which also revolves in glue or paste-box E', or a separate box if desired, being suitably mounted on shaftH, which may be geared up to shaft B as shown in Fig, 2; it being 'necessary with this glue wheel and shaft to have same revolve in a direction with the travel of the books as is true lwith the horizontally disposed rollers e', which is accomplished for example by the bevel gearing at .l see Fig. [is there are likely to be some inaccuracies in the length of the covers, that is the covers cut a trifle shorter than the size of the book or pamphlet, so that the cover would not extend over every part of the back, it is preferable not to have the entire surface of the backs provided with glue, which has a tendency to spread; and for that reason l prefer to provide the glue applying wheel er disk H with depressions or cut-out portions as shown at j (Fig. 3) so that the ends of the back will not receive glue. l

It is quite important in this class of machinery that the books be not provided with any glue where they are not to be covered, thus not only producing neater work, but also preventing interference with the proper working of the machine `resulting` from the" different parts becoming filled with glue. I

These lugs or lingers i therefore have the mechanism so timed, that the 'books will be fed forward so as to have the forward edge come over one of the depressions j and travel at the same speed a-S wheel H, while the other depression Will come beneath the forward edge of the next succeeding book. rlhe book having. been supplied with glue or paste on its sides and back, continues in its travel past wheel H and onto belt la, which may be provided with narrow transverse strips or projections 71:, or any other suitable means may be provided, so that the entire glued back edge will not come in contact with the mechanism and impede its operation.

As shown in the drawings, (see Fig. 3)

the rollers e do not extend entirely down to the bed or book-race plate, so that these rollers will not contact with that portion of the sides that have been supplied with glue. Belt is takes about wheels le which are actuated by chain c" taking about a gear mounted on shaft H', as shown in dotted lines in Fig. l. Belt 1, together with rollers e and chain f, will bring the books above cover-applying cylinder J, which is mounted on shaft K, which is geared to main driveshaft B at l (see Fig. 2). As an exemplification of my invention, cylinder J is shown of suoli diameter that but half a revolution will be necessary to apply a cover to a book, and therefore I have shown cylinder J provided with two sets of spring controlled grippingengers m at diainetrically opposite points as clearly shown in 3 and 8 These grippers m may be of a well known construct-ion and are tripped by any well known type of tripping mechanism as at P, consistingof a pin or lug on the frame of the machine which engages between the bifurcations of the member vii/Q' a detailed description of this feature need not be entered into. Mounted in close proximity to the cylinder J, is a sheet support-plate L, on which are piled the superimposed sheets which will constitute the covers for the books or pamphlets, as shown in Figs. l and 4. The plate L may be provided with screwthreaded extensions or ears through which the right and left screw-threaded rods M, M take, whereby the support-plate L with its superimposed sheets is automatically moved upward, rods M, M being turned through the action of gearing as at w, the gearing being mounted on shafts which are driven by a. chain or belt from main driveshaft B; rod M being shown as driven by shaft M with its bevebgearing, this shaft in turn being drivenv by rod M (see Fig. 4). The purpose of this automatic vertical movement of support-plate L is-to keep the top sheet of the superimposed sheets within reach of grippers m. Suitably mounted on the frame of the machine and near the edge gripper in the meantime has been tripped f Losanna of the pile of sheets beneath the cylinder is a pneumatic sheet-lifting mechanism comprising one or more suction-cups 0 preferably ,mounted on a tube or rod extending" transversely of the sheet-lift. This .tube or rod may extend or be secured between rocker-arms p (there being preferably one arm at each side of the machine) which arms are actuated by connecting link p', which 4link is connected with and actuated by rocker-arm g; pivotally secured atv 'g' to the frame of the machine. rlhis arm g 1s rocked by the action of cam r, mounted on the shaft K, against roller 7" secured to arm g. In order to permit of any necessary adjustment, the connection between .connecting "link p and arm g is preferably shown as a by any suitable tripping mechanism as for example that shown at P, which forces the tip of the gripping-linger away from the cylinder against the action of the spring which,

controls the grippers, and holds it open until it is passingfover the edge of the-sheet, when the lingers willbe released by the trip ing mechanism and through the action ofp the spring suddenly snap down ontothe paper edge and drawV the top sheet olf the pile and l from beneath the idlers Q, which tend to break the sheets and hold them firmly until the grippers carry theml onto the cylv inder J. The cylinder J is preferably of such size ythat the portion of the periphery of the cylinder between the gripping mechanisms is sufficiently large to accommodate a sheet and permit the same4 to lie dat against the surface. j

The pneumatic sheetlifting cups may be controlled by the action of what may be termed a detector arranged along the path of the book or pamphlet to be covered, and in advance of the cover-applying mechanism. v illustrated comprises the arm 9 pivoted' at 10 and connected at its one or long end with rod 11, which connects with bell-crank lever 12, connected with rod l-seeFig. 3. The lower end of this rod 13 is preferably bifurf cated. Arm 14 may have one end pivoted tothe frame of the machine as at 15 (see Fig. Li) while the. other end takes between the bifurcations and isy pivotally secured in place; The arm 14 takes beneath the eX- tended portion-of one oft-he arms p-as shown in Figs. 3 and l---and is adapted to The particular type of detector control the actionv of the arm 'p and thereby the operation of the. sheet-lifting mechanism. hebelhcranlt llever 12 is provided' with a lug lr6-'see Fig. -to which 'is -secured spring 17, whose other end is secured to the frame of the machine. rlhe tendency of spring 17 is to'pull on lng 16 and thereby rock lever l2 .toward the Aright in Fig. 3, which will pull rod ll and with it arm 9 into the normal position shown in Fig. 2,

with the .free end extending into the path or race-way-alongwhich the pamphlets to,

be covered must travel. It is' apparent' from the foregoing description that if for any reason a pamphlet should no-t have been fed to the race-way during the operation of the. machine, arm 9 will remain inits normal position. extending into the race way, throurghtheact-ion bf spring 17 Aon lever 12, holding up rod 13 and with it arm 14; 'arm 11i holds up arm p, so that even though cam r has turned to the positionwhere it would allow 'arm pand suction-cup o to drop, they cannot Adrop down and lift the top sheet of j '90 i The cylinder forces the sheet pickedv upl against the bach edge of the book which hasy the superimposed sheets-on cover-lift' L.

been supplied with glue'or paste. Extending over the cylinder and Jtakin'g' slightly below the vimmediate top ofthe cylinder, so

as. to extend into a plane just below the plane in which the bach of vthe book travels, are the blades or cover-lifting members t,

which are twisted or' formed with a flat surface presented upward as shown in- Fig. 2. The ends flare outward from eachother, as shown in this ligure, and gradually convergev with the dat surface or faces assuming a vertical position to take against the sides j of the book. lt is evident that the cover willrthus be gradually lifted against the sides ofthe book and held in a` vertical posi tion,` While the book and cover travel for-iward and pass 'over the grooved rollers s, s, which tend to more irmlyftorce the cover `on the-back of the bookand also press the samev against that portion offthe book sides near the 'back that has been provided with glue Ior other adhesive substance.

Located along the path of the boolrsy at any suitable point intermediatemf the cover' vapplying mechanism and the delivery end of These scorers 14 will crease or score' the cover just above or adjacent to the point where it is glued to the pamphlet, so' that, 1n opening less likely to pull away from the book or pamphlet at the point where 1t 1s glued.

' the pamphlet, the cover will'have a tendency A ,to fold along the crease or score and thus be It is apparent that the construction of the scoring mechanism may be altered, but it is thought t-hat the form selected is about the simplest in connection with the type of niachine illustrated.

R, R, are sets of rollers preferably arranged at an angle asshown for the purpose hereinafter set forth. The rollers may be adjustably arranged to accommodate books of different thickness and may be also yieldingly held to provide for slight variations in thickness. As the books pass between these rollers they are not only carried for- Ward toward the packer or receiving tray D, but are also put under an even pressure to insure the thorough sett-ing of the glue or paste; and with the rollers inclined as shown, the tendency of the cover to buckle is prevented by reason of the manner in which the pressure is applied. The books continue in a constant movement from the time they are fed from hopper A, through the action of belts, chains and rollers, or other suitable means, until they have been covered and delivered in the packer or receiving tray D, thus providing a continuous operating machine free from any vibrations or ars caused by the frequent stops necessary in the intermittently acting machines at present in use.

The packer l) may be of any suitable design and might be made to travel along a screw-rod S, which may have a constant or intermittent motionin accord with the speed of the machine; the packer moving along on rollers `in the run-way or frame T secured to the side ofthe machine. Should the shaft or rod S travel too fast, the packer may be disengaged and moved backward by lifting the weighted screw-threaded follower or described but arm U, as is evident from the construction shown in Fig. 7. It is apparent from that figure that the packer will be slightly shifted so as to present an unobstructed portion for the next. succeeding book.

lVith my invention a machine is provided which will be continuous in its operation; the books bcing.fed forward, glued, and provided with covers, which are also folded up against the book-sides, and the book with its cover put under pressure, without a break or stop in the operation of the machine, thus providing a machine of greater capacity than is true of those at present in use.y
