WILLARD I. LEWIS, OF WALPOLE, MASSACHUSETTS.

MACHINE FOR APPLYING FLY-LEAVES OR THE LIKE TO SIGNATURES OF BOOKS.

SPECIFICATION forming part of Letters Patent No. 774,726, dated November 8, 1904.

Application filed May 3, 1902. Serial No. 105,851. (No model.)

To ztZZ w/wm/ it may concern:

Be it known that I, WILLARD I. LEwIs, a citizen of the United States, residing at Walpole, in the county of Norfolk, State of -Massachusetts, have invented a certain new and useful Improvement in Machines for Applying Fly- Leaves and the Like to Signatures of Books, of which the following is a specification, reference being had therein to the accompanying drawings.

In the art of bookbinding one of the operations preliminary to assembling and securing together the signatures, &c., constituting the body of a book is to attach with the aid of cementitious material, such as glue or paste,

certain additional sheets to a portion of the said signatures. In some instances a single or unfolded sheet constituting a fly-l'eaf is united by one margin thereof to one face of each of the end signatures of a book, adjacent the inner or folded edge of the corresponding signature. Cuts and the like are united similarly to the appropriate signatures. In other instances a sheet which is folded upon itself at its middle is attached or united adjacent the fold thereof to the exterior of an end signature. Such a folded sheet is variously termed a fly-sheet or an end paper. In subsequently completing the binding operations one half of the said fly-sheet-or end paper is pasted to the inner surface of the adjacent side of the cover to constitute a lining therefor, while the other half constitutes one of the fly-leaves of the book. In the case of the first signature of a book the fly-leaf or fly-sheet or end paper is applied to the front of such signature. In the case of the last signature of a book the fly-leaf or fly-sheet or end paper is applied to the back of the same. In practiceacut or the like sometimesis attached to the front of a signature and sometimes to the back of a signature. Heretofore, so far as I am aware, the operation of attaching fly-leaves and the like to the end signatures and the like of books has been performed manually.

My invention has for its general object to provide an automatic machine of novel character by means of which single fly-leaves, folded or double fly-sheets or end papers, and

cuts, as well as other like parts of books, all of which for convenience of designation will be comprehended generically under the term fly-letves in the following description, may be attached to signatures of books or the like.

The invention consists in a machine for the said purpose, which I believe to be the first of its kind.

I will proceed to describe the invention with the aid of the accompanying drawings, in which latter I have illustrated the best form in which I have thus far embodied the same.

In the drawings, Figure 1 shows in side elevation a machine embodying the invention. Fig. 2 is an elevation of the side of the machine which is opposite to that shown in Fig. 1. Fig. 3 showsthe machine in plan,certain of the parts at the delivering end of the machine on the left-hand side in the said figure being omitted in order to show parts which otherwise would be hidden. Figs. 4 and 5 are sectional views on the order of diagrams, being intended more particularly to show the working relations of certain of the parts of the machine, many of the details being omitted, theplane of section being substantially as indicated by the dotted line 5 5, Fig. 8. Fig. 6 is a sectional detail showing chiefly the means of supporting the signatures and flyleaves when being united, the device for applying adhesive material to one edge of the signature, the backing-bar and its stop-pins,

and the clamping-bar. Fig. 6 is a sectional detail view designed chiefly to show the means of depressing the forward edge of the signature to place the glue-covered marginal portion of the same in contact with the fly-leaf. Fig. 7 is a view in side elevation, showing the same parts as Fig. 6 and certain other features adjacent the same. Fig. 8 is a view of a portion of the machine at the delivery end of the latter, partly in section on the vertical transverse plane indicated by the dotted line 8 8 in Fig. 5, showing chiefly the head-endregistering devices, which are termed hereinafter the side-jog devices. Fig. 9 is a view showing in plan the parts which are illustrated by Fig. 8, together withcertain immediately-adjoining parts, certain portions of I the latter being broken away in order to show features which otherwise would be hidden.

In my machine the signature and fly-leaf or other sheet which are to'be united to each other are fed into predetermined position in proper relation to each other. A line of glue or other suitable cementitious material is applied to the proper edge of one of the said parts, and the two parts having been properly presented with relation to each other they are subjected to compression to unite them and insure their adhesion to each other and then are discharged. The presentation of the signatures and leaves or sheets which are to be united thereto to the working parts by means of which the union is accomplished may be effected manually in some embodiments of the invention; but preferably 1 cmploy automatic feeding mechanism when convenient. lVhen folded fly-sheets are to be attached to the signatures, the said fly-sheets may be supplied to the machine in folded condition; but I prefer to provide the machine with automatic devices for folding the flysheets and conveying them to the place where they are attached to the signatures, and I have shown the machine provided with such folding and conveying devices.

Having reference to the drawings, the opposite side frames of the machine are designated a and a, respectively. Adriving-shaft is shown at Z), it having suitable fast and loose band-pulleys Z). Figs. 1 and 3. 1), Figs. 2 and 3, is a suitable hand-wheel or fly-wheel on said driving-shaft. From the driving-shaft Z) the variousmoving parts of the machine are actuated through suitable trains of motiontransmitting devices and connections.

The particular motion-transmitting devices and connections which are described hereinafter with reference to the drawings may be employed or not, as preferred. Specifically considered they do not constitute features of the invention.

The machine shown in the drawings is con structed to act to apply fly-leaves or the like to two signatures simultaneously, and accordingly some of the working parts are duplicated. In practice the machine may be built or arranged to operate upon one or more signatures at a time, as may be preferred.

I provide a suitable magazine or hopper for the reception of each stack or series of the signatures which are to have fly-leaves or the like applied thereto. At 0 0, &c., Figs. 1 to 5, are upright bars constituting the sides of each of the said magazines or hoppers, and into the inclosure constituted by each group of the said upright bars 0 0 a stack or pile of the signatures :0, Figs. 1, 2, and 3, is placed, 0, Figs i and 5, being the table on which the bottom signature rests.

The automatic mechanism for feeding the signatures (a from each magazine to the point in the machine at which the assembling of the signatures and fly-leaves is effected, when such mechanism is employed, may be of any suitable preferred construction in practice.

I have shown a convenient construction of feeding mechanism, which I will briefly describe as follows: For the purpose of separating the bottom signature from the pile of signatures above the same in each magazine in order that a pair of nippers pertaining to the feeding mechanism may properly engage with the said bottom signature preliminary to making the required transfer of the signature to the place at which it is to be united with the corresponding fly-leaf the said feeding mechanism is provided with a suction-cup (Z,(shown only in Fig. 1,) mounted at the free extremity of an arm d of a rock-shaft (Z the latter having another arm, (Z which is connected, by means of a rod (Z to a lever (Z which is pivoted at Z and actuated by means of a cam (Z Fig. l, on an auxiliary shaft 1, which is driven from driving-shaft 6 by means of a gear 2, fast on shaft 1 and meshing with a pinion 3, fast on shaft 6. By means of the cam (Z and described connections the cup is raised so as to press the same against the under surface of the bottom signature in the corresponding magazine and then is lowered, drawing down with it a short distance the forward (folded) edge of the said signature. For the purpose of exhausting the air from the suction-cup (Z in order to cause the bottom signature to adhere thereto 1 have shown in Fig. l the interior of the said cup connected by flexible tubing d with the cylinder d" of a suction-pump, the piston-rod (K of the said pum being connected with a lever (I the latter being mounted on a rock-shaft (Z having an arm cl, which is actuated in one direction to operate the piston of the said pump by means of a cam d on a second auxiliary shaft 4:, which is driven from the driving-shaft b by means of a gear 5, fast on shaft 4 and meshing with the pinion 3 on the shaft 1), the piston-rod and piston being acted upon in the opposite direction by a spring (Z The cam (Z oecasions the inward movement of the piston, while the spring is operative to occasion the outward movement thereof, by which the suction is occasioned. The rock-shaft (Z operates the piston-rod of the suction-pump (not shown) pertaining to the magazine at the other side of the machine by a similar arrangement of parts. To accommodate the swinging movement of the piston-rod al as it oscillates in unison with the curvilinear movements of the rocking arm (Z the pump-cylinder is pivoted, as at (Z to a suitable bracket (Z attached to the machineframe, this arrangement permitting it to swing in a vertical plane in unison with the piston rod. The bottom signature having been depressed below the level of the next succeeding one in the stack of signatures contained in the magazine or hopper, a separating-blade is interposed between the said bottom signature and the one next above. The separating-blades pertaining to the two magazines are shown in Figs. 1 and 2 at 6. Each thereof is mounted at the lower end of a depending arm 6. The two arms ee are fast upon a rock-shaft 0 which latter is journaled in the free extremities of arms 6 6 that are attached to a rock-shaft c journaled in suitable bearings which are provided at the tops of standards 6 0 located at opposite sides of the machine-frame. The rock-shaft e aforesaid, carrying the arms a e, is provided with operating connections comprising another arm, as e, a connectingrod e joining the same arm 6 with one arm of a bell-crank 0 Figs. 2 and 3, which is mounted pivotally upon a bracket, as a, at-

tached to the side frame a, the said bell-crank having also connected therewith a rod c which is in engagement with a cam e on auxiliary shaft 1. Movement transmitted from the said cam a through the connections described and acting with a tendency to swing the arm 0 upwardly will first .turn the rock-shaft 0 so as to swing each separator-blade in between the bottom signature, which has been separated and depressed, as aforesaid, and the signature next above the same. The swinging movement will continue until arrested by contact of the lower end of the arm a with the front guide-bar of the hopper or magazine. Thereafter the continued action of the cam 0 will operate to lift the assemblage e", 0 6 e, and e, causing the same to move around the axis of the rock-shaft at 9*. The upward movement of the separator-blades e 0' thereby produced acts to lift the stacks of signatures in, so as to relieve the bottom signature of each of the weight and pressure of those above the same, thereby facilitating the withdrawal of the bottom signature from beneath the stack in each magazine by the action of the signature-feeding nippers.

For the purpose of determining the position in which the separator-blades 6 shall stop after being withdrawn from beneath the stacks of signatures a: in the hoppers or magazines the rock-shaft is furnished with a projecting arm e Figs. 1 and 3, having applied thereto a set-screw a, that is adapted to engage with a suitable stopas, for example, a portion 6 of the adjacent standard 6 Fig. 1.

A pair of signature-feeding nipppers is provided for each magazine. Each pair comprises a fixed upper nipper-blade f and the movable lower nipper-bladef. The two pairs of nippers are carried by a movable carrier or frame g, to which latter movement to and fro, rearward and forward, is communicated for the purpose of carrying the nippers rearward into position to engage with the bottom signatures, which have been separated in the manner aforesaid from the signatures in the stacks above them, and of then carrying the nippers, with the signatures held thereby, forward to the place at which the said signatures are to. be delivered up to be combined with the flyleaves. For the purpose of actuating the said frame g'and communicating thereto its for-' ward and rearward movements I have herein shown the same mounted pivotally in the lower portion of the machine-frame, as upon a rock-shaft at g, Figs. 1 and 2, and connected by a rod, as g with a rotating crank, as g on the shaft 1'. For the purpose of moving the movable nipper-blade f of each pair of nippers toward and from the corresponding fixed nipper-blade f the said movable nipperblade f is mounted upon the lower end of the upright rod or pin the latter being mounted in a guide, as f, on the frame 9, in which guide it is capable of moving longitudinally. For the purpose of actuating the rods f f 2 of both pairs of nippers simultaneously I employ an operating-rockerf Figs. 1, 2, and 3, which is hung pivotally at f, Figs. 1 and 2, upon the movable frame g. One extremity of the said rocker has a fork or eye f for each rod f encircling the said rod between two collars or the like f f upon the said rod, aspring, as f, being interposed between the upper side of the fork or eye f and the upper collar f hen the rocker f is swung in a direction to carry its rear end downwardly, the fork or eye f by engaging with the lower collar f will move the lower nipper-bladef away from the upper nipperblade f, so as to open the nippers. hen the rockerf is swung in the reverse direction, it acts with a tendency tocompress the spring f and the said spring acting against the upper collar f transmits a yielding force to the rod whereby the lower nipper blade f is borne toward the upper nipper-blade f, thereby compressing the signature with yielding force between the two nipper-blades. The

rocker f is actuated by means of a rod f which at one extremity thereof is connected to a projection f of the rocker and at the other extremity thereof is joined to a radiusarm f Figs. 1 and 2, a second rod f extending from the said radius-arm to a lever f which last is pivoted at and actuated by means of a cam f", Fig. 2, on the auxiliary shaft 4:.

1n the working of the machine the frame g moves rearwardly to carry the nippers ff into their rearward position, the said nippers having been opened. The nippers are then permitted to close upon the lowermost signature in each magazine, the front edge of the latter having been separated from the piles above by the action of the separator-blades, as aforesaid. The frame Q then moves forwardly, the respective pairs of nippers carrying along with them the said signatures. Having been carried to their foremost position, the said hippers are opened, as in Fig. 5, so as to release the signatures, each of which falls fromthe nippers upon the upper Illusurface of an inclined table It, Figs. 4, 5, 6, 8, and 9. The incline of this table may in practice be such as to cause the signature to move by gravity down the same until the folded edge of the signature brings up against the stop-pins z 6 upon the bar 77. I usually prefer, however, to facilitate and insure the movement of the signature into position against the stop-pins t' by the employment of suitable means for advancing the signature after it has reached the table it. A variety of means may be employed for the purpose. Herein I have shown a rotatable roll it and endless feeding-tapes h", the said roll a being driven by suitable gearing hereinafter described. The signatures having been positioned against the stop-pins 2' t', a line of glue or other cementitious material is now applied to the lower face of each of the same closely adjacent the folded edge of the signature. The construction and mode of operation of the glue-applying device or paster may vary in practice. I have herein shown a construction which is of my owninvention and which for many reasons I prefer to employ. It consists of a dabbingstrip 7:; for each magazine. The two dabbingstrips 7c it are mounted upon a shaft k, the said shaft extending across the machine and being provided at its opposite ends with crank-arms Figs. 1, 2, 3, and 7 each crank-arm having a crank-pin 70 The centers of the said crankpins coincide with the acting edge of the dabbing-strips 71; it in distance radially from the axis of the shaft k. (See more especially Fig. 7.) The said crank-pins 7c are fitted in eyes at the free extremities of radius-arms is 7a, which last are hung upon pivots at 70 75", carried by brackets is is, fast to the machineframing. Upon the shaft it" is made fast a gear Figs. 1, 3, and 7, meshing with a pinion it' which is loosely mounted upon the shaft m of the glue-roll m, the said pinion it' having fast therewith the sprocket-wheel is, which is engaged by the sprocket-chain 70 the latter also passing around an actuating sprocket-gear 70 on the auxiliary shaft 1. The ratio between the sprocket-gear7c and the sprocket-pinion is is the inverse of the ratio between the pinion 7B8 and the gear 70 By means of links k In, Figs. 2, 3, and 7, extending from the shaft 7a to the shaft on, the gear 70 and the pinion 70 are held at all times in mesh, but with capacity on the part of the gear is and shaft it" to oscillate forwardly and rearwardly in an arc about the axis of the shaft m. The radius-arms Z5 75 by their engagement with the crank-pins [L3 confine the said crank-pins to substantially vertical movement in an arm described about the axes of the pivots if if as a center. The result in practice is that when the shaft is is rotated by means of the pinion F and gear k the acting faces of the glue-applying strips 70 7c are caused to make a nearlyvertical slightly-rolling contact with the surfaces of the gluerolls m m. The glue applying strips then turn over, and as they do so the acting faces thereof ascend, moving in a vertical arc concentric with the pivots k 76 until in ascending the said acting faces come uppermost and make a nearly vertical slightly-rolling contact with the signatures adjacent the folded edges of the latter, after which the glue-applying strips k 76 descend, turning over in their descent until they make similar contact again with the surfaces of the glue-rolls, after which they rise once more toward the next succeeding signature. The glue-rolls are mounted upon the shaft m, which latter is rotated by means of a gear m thereon. Figs. 2 and 3, meshing with agear m of equal diameter therewith on the shaft L of the glue-applying devices. The gluetroughs beneath the glue rolls m m are shown at n n.

For the purpose of furnishing a backing or support for the folded edge of the signature at the time at which the acting edge of the glue-applying device 76 is thrust against the signature in applying glue thereto the bar c" is depressed from the intermediate position which it occupies when the signature is first delivered against the stop-pins z' 7 into the position in which it is shown in Fig. 5. Hence by the rise of the glue-applying device the folded edge of the signature becomes compressed between the said device and the edge of the bar a, as in Fig. 6. There is a bar a for each side of the machine, each of the said bars being carried by swinging arms a One of the said arms a has connected with the axis thereof another arm, a, to which is joined a rod or bar a, that is in operative connection with a cam c, the cam for one side of the machine being on the auxiliary-shaft 1, while that for the other side of the machine is on the auxiliary shaft 4.

For the purpose of preventing the signature to which glue has been applied by the ascent of the glue-applying device 1 1; from adhering to the said device and being drawn down thereby in its descent means is provided for stripping the signature from the acting face of the glue-applying device. Thus a clamping-bar p is arranged above the table 71. (See Figs. 3, 6, and 7.) This bar is mounted on swinging arms, 1) p and normally is held lifted by a tension-spring 2 Fig. 7. When the bar t" is depressed, it makes contact with one of the arms p p, and thereby forces bar p down, so as to hold the signature clamped between the bar 1) and the table it, the signa ture being held clamped in this manner until the glue-applying strip k has completed a part of its descent and separated from the signature. In order to prevent a signature in be ing advanced toward the stop-pins idfrorn accidentally passing above the clamping-bar p, the latter bar is furnished with upwardly-inclined guides p Figs. 6 and 7 which act to deflect the forward edge of the signature be- I 0, and a spring 0", which is connected with neath the said bar 19. Glue having been applied to the signature resting against the stoppins z, the said signature is in readiness to have the fiy-leaf joined thereto. A shelf or table 0 is located a slight distance below the forward edge of the table it. This shelf or table 0 serves to support the fiy-leaf when the latter is advanced upon the same after the glue-applying strip is has been moved away from the signature. Prior to the said advance of the fly-leaf the bar 2" is raised a short distance. This relieves the pressure of the bar 19, by which the signature is clamped against the table it and by which also the forward edge of the table is held depressed slightly below its normal position. As the bar rises, therefore, the clamping-bar becomes elevated by the action of its spring 12 and the front edge of the table it rises also, lifting the glued portion of the signature slightly, so as to afford clearance for the front edge of the fly-leaf as it passes forward upon the shelf or table 0 Thereby contact of the front edge of the fly-leaf with the glue on the signature is avoided and the fly-leaf is not hindered from moving forward into proper position against the stop-pinsz' 2'. Feed-tapes 0 0 serve in the machine shown in the drawings to advance the fly-leaf into position. beneath the table it and over the table 0 with its front edge in contact with the stop-pins 2' c'. The said feedtapes 0 0 pass around a supporting and guide roll 0, which is located adjacent the table 0 and also around other supporting and guide rolls 0 0*, 0 and 0 in the rear part of the machine. For the purpose of driving the roll 0 and actuating the tapes 0 0 the roll 0 is provided with a sprocket-wheel 0 and a sprocket chain 0 passes around the said sprocket-wheel and around a sprocket-wheel 0 on the driving-shaft b. The fly-leaves which are to be fed by the tapes 0 0 are placed upon a table 0 at the rear of the machine and pass thence onto the horizontal relatively elevated rear portion of the feed-tapes. For the purpose of timing the feed of the successive flyleaves feed-gages of are employed. The said feed-gages being in their normal depressed position upon or adjacent the upper surface of the feed-tapes 0 0, afly-leaf is advanced by hand or otherwise until its front edge rests against the said feed-gages, which latter hold the flyleaf back until the feed-gages are lifted. The lifting of the feed-gages to permit of the forward movement of the fly-leaf with the feedtapes 0 0 is efiected periodically by suitable devices which are provided for the purpose. Herein the feed-gages'are carried by swinging arms which are attached to a rock-shaft 0 the latter having an arm 0, which is connected, by means of a rod 0 with one arm of abell-crank 0 which is acted upon by a cam 0 on the auxiliary shaft 4. The said cam 0 operates to cause the lifting of the feed-gages the rod 0, acts to depress the same.

Presserrolls 0 are provided at the rear of the feedgages o These rolls are mounted on arms 0 attached to a shaft 0 located above the feed-tapes 0 0. The said shaft 0 has an upwardly-extending arm 0, which is connected by a rod 0 with an upwardly-extending arm 0 fast on the shaft 0 of the feed-gages. Normally the presser-rolls 0 occupy a position in which they are raised slightly above the upper surface of the feed-tapes 0 0.

When, however, the feed-gages are raised so as to release the fly-leaf, the presser-rolls are lowered so as to press the iiy-leaf against the feed-tapes, thereby insuring that the fly-leaf shall be fed forward by the said feed-tapes. The guide and supporting rolls 0* 0 elevate the rear portions of the feed-tapes 0 0 slightly above the forward portions of the same, and the said feed-tapes pass down between the rolls 0 and 0. As the fly leaf, which is gripped between the presser-rolls 0 and the feed-tapes 0 0, is advanced its forward edge passes on horizontally beyond the rolls 0 and 0 onto a table 0 until it brings up against a stop-gage 0 For the purpose of folding or doubling the fly-leaf transversely upon itself automatically a folding-blade p is provided at each side of the machine. The two folding-blades p 1? are carried by arms 7f, which are attached. to a transversely-extending shaft 1), and the said shaft is operated by means of an arm p with which it is provided, the said arm 79 having connected therewith a rod or bar 19 which is in operative engagement with a cam 19 on the auxiliary shaft 4. By means of the cam and connections described the folding-blades are depressed at thcproper time upon the fly-leaves below the same, so as to press the middle of each fly-leaf into the bight of the rolls 0 0", whereby the flyleaves are fed forward and folded upon themselves in well-known manner. To assist in driving the rolls 0* and 0", a sprocket-chain 0 is passed around sprocket-wheels 0 and 0 upon the said rolls, and the rolls 0 and n are geared together, as at 0 0 Auxiliary presser-rolls 0 0 are provided in front of the presser-rolls 0 to hold the fly-leaf in con tact With the feed-tapes 0 0. A fly-leaf having been advanced upon the table 0 beneath the signature which rests upon the table it and the front edges of both the signature and the fly-leaf being in contact with the stop-pins 2' 2', the head ends of the same are brought into proper correspondence by means of the head end registering device, which I will now describe and which I have termed the side jog. The details of the head-end-iegistering or side-jog mechanism are shown in Figs. 4, 5, 8, and 9. The said details are mostly concealed from view in the elevations and are omitted from the other views to avoid complication. They are duplicated in the machine to correspond with the number of signatures being operated upon at one time. Having reference to Figs. 4, 5, 8, and 9, 1 designates a gage or plate for making contact with the head ends of the signature and flyleaf. This gage is mounted to move transversely within the machine and has attached thereto a rod 9. The said rod passes through a hole in a bracket (7 and is encircled by an expanding spiral spring g, which is compressed between the said bracket and a collar Q4, that is secured to the rod. For the purpose of moving the rod 9 and gage q laterally of the machine in a direction to compress the spring a lever q is provided, it being pivoted at q and having the upper arm thereof forked, as at 1 to engage with a pin (1*, carried by a collar which is secured to the shaft. The other arm of the said lever ([5 carries a roller Q10, which is acted against by the cam-face g of an arm 9, extending upward from the rock-shaft g, on which the frame or carrier g for the nippers is mounted. hen, therefore, the nipper carrying frame 1 is moved rearwardly in the machine, the camface Q11 acts against the lever 1f to move the rod q and gage q in a direction to compress the spring q. When the nipper-carrying frame returns to its forward position, the spring is permitted to act, and it moves the gage g in the opposite direction. The contact of the said gage in its movement with the head ends of the signature and of the fly-leaf below the same occasion a shift of these latter lengthwise in a direction extendingtrans- Versely of the machine, bringing the said head ends into proper position with relation to each other. The signature and fly-leaf having been adjusted into proper position, as just described, the forward edge of the signature is depressed slightly, so as to place the glue-covered marginal portion-of the face of the same in contact with the corresponding marginal portion of the opposing or proximate face of the fiy-leaf. For the purpose of effecting this depression the clamping-bar is caused to be forced downwardly upon the top of the sig nature again, so as to effect the required lowering of the same and of the front portion of the table 70. To this end the nipper-carrying frame 9 is provided at one side of the path of the signature and fly-leaf with a cam 9', which, in the movement of the said frame rearward for the purpose of enabling the nippers ff" to engage with the bottom signatures in the magazines, acts against the cam-shaped portions 12 Fig. 6, of one of the arms 1) of said bar 19. The pressure of the said bar 1) against the upper surface of the signature lying upon the table it bears the forward portion of the table A down bodily. Thereby the signature is carried into contact with the fiy-leaf below the same without displacement of the forward edges of the two relative to each other in consequence of the operation of .bringing them together.

For the purpose of causing the signature and fly-leaf to unite perfectly along the line on which the glue is applied to the signature the forward edges of the two are compressed tightly together. In the present instance I employ a pair of nippers s s at each side of the machine for the purpose of eifecting this compression. These nippers are carried by the frame or carrier 9 and are operated by the rocker f in manner substantially the same as the nippers ff, which transfer the signatures from the magazines to the tables h. The nipper-blade s is the fixed blade, while the nipper-blade s is the movable one, the latter having connected therewith the upright rod 8 moving through a guide on the frame g at and the upper portion of the said rod having fitted thereto the fork or eye 8 of the rocker Collars s s are secured to the said red at opposite sides of the fork or eye 8 and aspiral spring s encircles the rod between the fork or eye s and the lower collar 3, so as to cause the movable blade 8' to be moved with yielding force toward the nipper-blade s. The nippers s s are carried by the rearward movement of frame or carrier 9 into position to engage with the signature and fly leaf which have been brought together in manner aforesaid, and the said nippers having been closed upon the signature and fly-leaf, so as to effect the compression, the ensuing forward movement of the nipper-carrying frame causes the signature and fly-leaf together to be drawn forward from the tables 72. and 0 Just before the nippers s and s commence the discharge movement the blade 71, carrying the stop-pins '11, is caused to rise by the cam 77, so that the paper may pass out under the pins 7' a. (See Fig. 4.)

For the purpose of discharging the signature and attached fly-leaf from the nippers s s as the latter complete their forward movement a small rock-shaft tis mounted upon the nipper-carrying frame, it being provided with a series of downwardly-extending arms or wires 25 and also being provided at one end of the same with an arm t to coact with a cam i which is aflixed to a bracket 6" on the forward part of the machine-framing. When in the advancing movement of the frame g the arm 25 encounters the cam t the rock-shaft z. is turned so that the arms or wires t thereof push the signature rearwardly from between the nippers s s.

The roll It is driven from the roll 0 by means of the gears z 2 .2, Figs. 6 and 7 In order that the bar a may yield to accommodate the thickness of the signature when the glue-applying strip 7:; in its rise compresses the signature against the edge of the said bar, the cam 2", which actuates the said bar, is arranged to act to raise the bar, while the depression of the bar is effected by means of spring i connected with the rod or bar a, which engages with said cam. Thereby the strip after it has nearly turned over in its rise into position to contact with the signature. It will be apparent that the working edge of the dabbing-strip moves in a path which enables the forward edge of the support 0 for the fly-leaf to be extended into close proximity with the forward edge of the signature to which the fly-wheel is about to be attached. In other words, the path of the dabbing-strip is such as to enable the front edge of the supporting-table 0 for the fly-leaf to be located in position to sustain the fiy-leaf closely ad jacent to its front edge. This insures against displacement of the free forward edge of the fiy-leaf and enables the same to be properly applied to the signature.

While in the case of the illustrated embodiment of the invention I have explained the parts as operating to cause the glue or cementitious material to be applied to the signature preliminary to causing the fly-leaf or the like to become attached thereto, this is not necessary in all cases, and I also contemplate applying the glue or cementiti'ous material directly to the fly-leaf or the like.

The duplication of the working parts of the machine shown in the drawings enables me advantageously to utilize one set of the said parts for the attachment of fly-leaves to the fronts of those signatures with which such attachment is necessary and the other set thereof for the attachment of fly-leaves to the backs of those signatures with which the latter attachment is required. The simultaneous operation of the two sets of working parts enables the work of attaching fly-leaves to the fronts of one set of signatures to be performed concurrently with that of attaching fly-leaves to the backs of a second set of signatures. To these ends I simply place the two head-endregistering gages or side jogs q q in opposite relations with respect to the'supports at the opposite sides of the machine against which the signatures and fly-leaves rest while in process of being united to each other. This causes the gaging devices to operate in reverse relations with respect to the duplicate attaching or combining devices. In the illustrated machine the said head-end registering-gages or side jogs are located adjacent the middle of the width of the machine, one thereof being in position to act outwardly against the inwardly-directed"head ends of a signature and fly-leaf resting upon the supits head end toward the middle of the width of the machine, the front face of the same will be turned down in position to have the fly-leaf attached to such face, while in the case of the signature at the right-hand side of the machine, it having its back edge similarly presented to the pins 2' and its head end toward the middle of the width of the machine, the back face of the same will be presented downward to have the fly-leaf attached thereto.
