PAIVIPHLETeCOVERNG MACHINE.

To all whom it may concern:

Be it know'n that I, PETER PAoHTnn, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a` certain new and useful Improvement in Pamphlet-Covering Machines, of which the following is a description. i

My invention relates to a machine for attaching the paper or other flexible covers to la book or pamphlet, and has for its object the provision of a single machine whereby vthe covers will not only be secured to4 the back of the book or pamphlet but also to the sides for a predetermined distance, thereby providing the book or pamphlet with a cover more irmly secured in place than is `the case with the method of machines at present in 7 use, .and at the same 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 objectof the invention is to Aprovide a machine that rwill not only be automatic in its operationand will permit of its adaptation to books or pamphlets of varying` sizes; but will be continuous in .its operation.y thereby giving it greater capacity ithan that of the. machines now employed` which operate intermittently; finthermore, my improved machine does not possess the serious objections found in the intermittent type of machines at present employed towit the jar and vibration caused by the frequent startingand stopping,` of such type of machine, which is not only a wear and tear on the machineitself but also on the struc-ture in which it is loc-ated,a.lso creat-ing considerable noise.

To the attainment of the objects and advantages referred to this invention consists in the novctmachine combinations, mechanisms and devices herein illustrated or described;

Application for reissue Itravel of the pamphlets or other books, and

vthe mechanisms Awhich operate upon the bool; specihcallybeing progressive in their action, and preferably of, a rotary nat-ure,

so that not only interruptions of .pamphlet travel are avoided, 'but valso the need of bodily'7 reciprocating the several mechanisms. ln its complete aspect the machine of this invention comprises the following mechanisms: The first mechanism is a` conveyer hy which a succession, of pamphlets are held, guided and Carried or advanced with a continuous and `preferably steady travel from the book infeedingl point throughout the several operations to the dclivery; specilically .this comprises a guiding racewa)l together with an endless device or chain having,` ju'ttingamt pamphlet-engaging' members which properly determine the longitudinal position or spacing,` of the successive pamphlets.y which advance in a vertical plane with their backs exposed down wa-rdl y.

The next mechanism is one for iautomatically feeding' or introducing the successive pamphlets one at a time into their proper positions in the traveling' conveyor, preferably byan infeeding' movement at an angle or i The ne'vt nuchanism is an automatic adhesive applying means larrangcal to operate progressively to appl),T glue to the. backs of the books znlvancina` in the conveyor; specifically this comprises glue rollers beneath the conveyor arrangei to apply glue not merely to the'bacli. but to the rear margins of the opposite sides of the pamphlet, a recess inthe roller serving to restrict the adhesive to pre-arranged points. The next mechanism comprises a device of a rotary nature in the form of a transversetv to the direction' Aof conveyer travel.

Coperating with thls rotary cylinder' Vdevice is a cove`r-supply .support and means' for automatically sepaprogressive operation from the infeeding tov -which latter has associated with it a machine.

.The presence or absence of the pamphlet controls the operativeness or inoperative ness of the feeding mechanism, so that no cover will be supplied when there is no pamphlet. The next mechanism is for bending, pressing or breaking the two opposite sides of the cover against the sides of the pamphlet. This mechanism is located ad#V jacent the conveyerand has portions which advance in unison with phlet while acting on the two-sides ofthe cover. Preferably this mechanism is ofa rotarynatu-re so as to progressively effect the breaking during the continuous advance of the pamphlet and cover after the uniting ofthe two by theprevious mechanism. The final mechanism is a delivery at the end of the conveyercomprising a suitable receptacle for the completed ip amphlfets. These combined mechanisms give continuous and the delivery, Ithus attaining to the fullest extent the objects before mentioned.

The advantages of my invention will more fully appear from the detailed description of the drawings of a machine embodyingr my invention and` which specification.

at one end uplonwhich is. supponted `the -feed-box or hopper A, which is preferably' mounted above the bed-plate ortop of .the machine. This hopper contains the unbound books or pamphlets'to'be covered, which are to be fed from the bottomby means of a belt-or provided at predetermined points with lugsA or projections a. The belt a, takes about rollers or pulleys b, lf; the one roller, for cXa-mpleroller b, receiving power by means of a pulley or belt, chain orV other suitable mechanism, from drive-shaft shaft in turn" is driven by be`lt from the power-shaft. Drive-shaft B maybe used to supply lpower to the different parts ofv the machine in any of the Well known ways The bound lbooks are placed in the hopper or feed-box A with their backs or bound edges presented in the direction of travel of belt e, so that as lug or projection a catches or takes against the lowest book, it will be carried by belt or chain a beneath roller c and dropped down between guides d, d, onto the bed or book race-plate C (see Fig. 5), `where it passes between rollers e, c, which may be driven in any suitable manner as for examplebysprocket-chains f which take about sprocket wheels g, g", either one 4 or both of said wheels being driven in any suitable manner. The rollers c, maybe mounted as shown in Figs. 5 .and 6 with their -endsheld bythe pillows or blocks c em; the position of the latter being controlled by the screws e4 and er' ,whichI take through the frame of the machine and .into or against the pillovvse4 em.' In addition to the action of-the rollers to carry the b oo'ks or pamphlets forward along the bed or raceY i plate, the chains f may also be provided with small lugs or fingers f', arranged on the 105 points, to ,take against the rear edge of the book and compel These lugs or lingers may be so arranged as to permit of their readyadjustment at any point on the chain so as to accoimnodate books or pamphlets of dii'erent'lengths. T/hc 'books are held between the chain and rollers and fed along until they have received the cover, when they i will be held between the blades or guide. rods li, L, and angularly arranged' rollers until they reach the packer or receiving tray D, at the end of the machine, see Fig'. 1. -As the book travels along between ,the rollers e, and the chain f, its sides neartheback-edge comev between the small horizontally arranged rollers vf, which take against the glueor wheels E, E, which are suitably mounted and 'revolve in the glue or pastebox E lnountedfbeneath the bed or book-'race plate C; the glue or paste box E 4 may be of any suitableconstructon,(see Figs. l and v5). i f

The disks or rWheels E, E,.are"suitably mounted on a shaft F, which niay be driven secured to the sides of the book;

.would not extend over every in any well known manner as for example by providing shaft F with bevel gear F' meshing with bevel-gear G, mounted on the drive-shaft B, (seelfigs. 2 and 5). Rollersi are of a thickness to correspond with the desired extent yto which the covers are to be this extent preferably being just sufficient 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 theirbacks -into contact with glue or paste-applying wheel or disk H, which also revolves in glue or pastesbox E, or a separate box if desired, being suitably mounted on shaft H', which may be geared up to shaft B as shown in Fig. 2; it being necessary with this glue wheel and shaft to have ysaine revolve in a direction with the travel of the books as is true with the horizontally disposed rollers i, which is accomplished for example by the bevel gearing at I see Fig. 2. As 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 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 ttor4 that reason I prefer to provide the glue applying wheel or disk H with depressions orA cut-out portions as shown at j (Fig. ill so that the ends of the back will not receive glue.

It is quite important in this class of inachinery 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. l therefore have the mechanism so timed, that the books will be. fed for 'iard so as to have the forward edge come over one of the dcpressions y' and travel at the same speed as wheel H, while the other depression y' will come beneath the forward edgeol: the next succeeding book. The book having been supplied with glue or paste on its sides and back, continues in its travel past wheel H and onto belt In, which may he provided with narrow transverse strips or progections J, or any other suitable means kmay be provided. so thatfthe entire glued back edge will not come in contact with the 1 .echanism and impede its operation. l t

As shown in the drawings, (see Fig;

as showi.; in f dotted Belt 7c, together with vrollcover-applving cylinder J, which is mounted on shaft K, which is gea-red to main driveshaft B at l (see Fig. 2). As an exemplification of my invention, cylinder J is shown of such diameter that but half a revolution will be necessary to apply a cover to a book, and therefore l have shown cylinder J provided with two sets of spring controlled .gripping-lingers m at diametrically opposite poi-nts as clearly shown in Figs. 3 and 8. These grippers m may be of a well known construction and are tripped by any well known type of tripping.mechanism as at P, consisting of a pin or lug on the frame of the machine wliicli engages between the bifincations of the member m, 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. 1 and (l. The plate L may be provided4 with screw- .threaded 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 n, the gearing being mounted 'on shafts which are driven by a chain or belt from inain driveshaft l5; rod M being shown as driven by shaft M `with its bevel-gearing, this shaft in turn being driven by rod M (see Fig. 4). The purpose of this automatic vertical inoven'ient ot support-plate li is to keep the top sheet of the superimposed sheets within reach ot' grilipcrs m. Suitably mounted on the frame of the machine and near the edge of the pile of sheets beneath the cylinder J, ,is a pneumatic sheetdit't'ing mechanism coniprising one or more suctioncups o preferably mounted on` a tube or rod extending transversely ot' thc sheet-lift. 'lhis tube or rod may extend or bc secured between rocker-arms ',l/ (there being preferably one arm at each side of the machine) which arms are actuated b v connecting link p, which link is connected with and actuated by rocker-arm (I, pivotally secured at q' to the frame of the machine. This arni (l is rocked by the action of cani l', mounted on the'shaft K, against roller-x7" secured to arm y. In order to permit of any necessary adjustment, the connection between connecting link p' and arni f] is preferably shown as a` slot and pin connection. sce Fig. S. The cain 'J' is so arranged on the shaft. to which *cylinder l is secured, lthat the sheet-lifting mechanism or cups will be pressed onto the sheet or cover-lift L on the cylinder' are will lOO

, the bifurcations per reaches'the edge Ytip of ,to the frame .14 holds up arm p, V1' has turned to the lift the sheet-lifting mechanism with the edge of the top sheet just before the gr1p' of the paper. `The gripper in the meantime has been tripped by any suitable `tripping mechanism as for example that shown at P, which forces the the gripping fingers away from the cyl,- mder against the action of the spring which controls the gripners, and holds it open until it is passing over the edge of the sheet, when the fingers will be released by the tripping mechanism and through .the action -`of the spring suddenly snap down onto the paper l edge and draw the top sheet 0H' the pile and from beneath the idlers Q, which tend to break the sheets and holdthem firmly until the grippcrs carry them onto the cylinder J. The cylinder J is preferably of such size that the portion of the periphery of the lcylinder between the gripping mechanisms is sufficiently large t0 accommodate a lsheet and gpermit the same` to lie flat against the surface.

he pneumatic sheet-lifting cups'may be controlled by the action of what may be termed ar detector arranged along the I path of the book or pamphlet to be covered,

and in advance of the cover-applying mecl anism. The particular type of Ldetectorf illustrated comprises the arm i) pivoted at' l() and connected at-its one or long end with` rod 11, which connects with bell-crank lever 12, connected with rod l-see Fig. The lower end of this rod 13 is preferably bifurcated. Arm 14 may have one end pivoted of the machine as at 15 (sec the other end takes between and is pivotally secured in place. The arm 14 takes beneath the extended portion of one oi' the arms p-as shown'in Figs. 3 and alt-'and is adapted to control the action of the arm p and thereby the operation of the sheet-lifting mechanism. The bell-crank lever 12 is provided Witha lug 16-sce Fig. 3to which is secured spring 17, whose other end is secured to the frame of the machine. The tendency of spring 17 is to pull on lug 1G and thereby rock lever 12 toward the right in Fig. 3, which will pull' rod 11 and with it arm 9 into the normal position shownin Fig. 2,' with the free" end extending into the path or race-way along which the pamphlets to be covered must travel. It is apparent from the foregoing description that if for -any reason a` pamphlet should not have been fed to the race-wav during the operation of the Fig. n while machine, arm 9 will remain mits normal position extending `into the race Way, through the action of spring 17 on lever 12, holding up rod 13 and with it arm 14; arm so 'that even though c am position where it would allow armV p and suction-eup o to drop, they the tendencyof the cannot drop down and lift the to sheet of the superimposed sheets on coverlft L.

The cylinder` forces the sheet picked up against the backedge of the book which has been supplied with glue or paste. Extending over the cylinder and taking slightly below the immediate top as to extend into a plane just below the plane in which the back of the book travels, are the blades or cover-lifting members IQ", which are twisted or' formed with a flat surface presented upward as shown in Fig. 2. he ends flare outward from each other as shown in this figure, and gradually converge of the cylinder, so

with the flat surface orfaces assuming a vertical position to take against the sides of thebook. It is sides of the book and held in a vertical position, while the book and cover travel forward and passfover the grooved rollers s, s, which tend to more firmly force the cover near the back that has been provided with glue or other adhesive substance.

Located along the path of the books at any suitable point intermediate 0f the cover# less likely to pull away from the .book or` evident that the cover 4will thus be gradually lifted against the the pami where it s on the back of the book and also press the f same against'that portion of the book sides pamphlet at the point where' it is glued.

lIt 1s apparent that the construction of the scoring mechanism may be thought that the form selected is aboutthe simplest in connection with the type of ma? chine illustrated.

R, are sets 'of rollers'A ranged at an angle as shown for the purpose hereinafter set forth. The rollers 'may be 'adjustably arranged t0 accommodate books of different thickness and may be also yield-4 inglyheld to provide for slight variations in thickness. As the books pass 'between these rollers they arenotfmly carried for- Ward toward thepacker or but are also put under an even pressure to preferably arreceiving tray D,

altered, but itis insure the thorough setting of the glue or paste; and'twith throllers inclinedas shown,

cover to buckle is prevented by reason ofthe mannerin which the pressure is\applied. The books 1,25 `continue in a constantnovement from'the time they are fed from hopper A, throughthe action lcated adjacent to backs and sides for of belts,

means, until they have been covered and dechains and rollers', or other suitable livered in the packer 0r receiving tray D, thus providing a continuous chine free from any vibrations or jars caused by the frequent stops necessary in the intermittently acting machines at present in use; and the devices s, R and l@ act to effectively fold, bend or break the covers against the sides of the pamphlet.

The packer D may be of any suitable design and might be'made to travel along a screw-rod S, which may have a constant or intermittent motion 1n accord with the speed D of the machine; the packer moving along on rollers in the Yrun-way or frame T secured to the side of the machine. Should Ithe shaft or rod S travel too fast, the packer may be disengaged and moved backward by lifting the weighted screw -threaded follower or arm U, as is evident from the construction shown in Fig. 7. It is apparent from that ligure that the packer will be slightly shifted so as to present an unobstructed portion for the next succeeding boolr.

lith my invention a machine is provided which will be continuous in its operation; the books being fed forward. glued, and pr vided with covers, which are also folded up against the book-sides, and the bool( 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.
