. Referring particularly. to Figs. 1, 2, and-3,

a represents a frame at one end of the signature-gathering machine; a', a bracket mounta, a plate-support for a group of signatures; ail-a sucker device for bending down the lowerinost signatures one at a time; a, a swing-- ing gripper-arm adapted. to engage the lowermest bent-down signature and remove.

short shaft a in bearings 'also formed as part At one end of the.

of athis bracket-support. short shaft all is'a sprocket (L12, and there is a second sprocket als in line with the sprocket (L12, thelatter upon the power-shaft b, said sprockets being connected by a chain, the power and rotation being communicated by the shaft b through the sprockets a and al1-2 andthe intervening parts described to the `-sprocket or chain wheel a7 for driving the conveyer-chain ay and its pins. This powershaft l; is provided with a couplingb, receiving and secured to a smaller prolongation of said power-shaft, also carrying a referenceletter b. The signature-guiding trough c, Figs. 1 and 2, is at its left-hand end connected to, and it forms a prolongation of the signature-trough a5 and extends, as shown in Fig. 2, 'to the reciprocating wire-stitching devices. Moving along through this trough c and in a guide c7 is a conveyer-chain c, with pins, which at one end passes around the pulley c2, having suitable bearings, and at its other end around a sprocket c3, secured to the upper end of a vertical shaft c, aldo in suitable bearings. At the lower end of the shaft c4 there is a worm-wheel c5, occupying al horizontal position and meshing with a worm-wheel' c on an auxiliary shaft e, horizontally placed vand in suitable bearizgs in the bedfframe el of the wire-stitsbingi devices. Conveyer-chains a and c are so timed in their movements with respect to each other that as a pin upon the chain a6A passes away from the completed book of signatures a pin upon the chain .cis in position to take said book of signatures and convey the same from the trough a/5 to the trough c. f

The power-'shaft b- 's provided with a ,sprockete (see Fig; 4) .and said-auxiliary shaftye with a sprocket e2, a chain ealpassing i' i around said sprockets, so as to communicate' the power and rotation from theshaft b to the shaft e and fromthe shaft e, through the worm-wheels' c5 c, to the shaft c4 and and progress the superimposed piles ofsignatures or'sheets from the si nature-gathering machine to the reciprocating wire-stitching devices.

signature-trou.ghe5 at the end of the gathering-machine, and the trough ccontinues this inclination; but, as illustrated in Figs. 1-2 to 1 Y 15, inclusive, this 'trough c is so bent as 1t 8o progresses in length that the piles of signatures or sheets are graduallyturned from an inclined into an almost vertical position. In factQ'they do come into a vertical position, as

shown in Fig.- 5, at the place Where the Wire 85 stitching or stapling is performed, and in this position the stitched signatures rest upon their folded-back edges, and I provide in connection'with the signature-guiding trough c guide bars or racks v v" in vpairs coming at 9ov opposite sides ofthe signatures and conforming to the curve of the. trough c, so that the signatures or sheets in their movementrest alike on said bars or racksand on the trough.

The bed-frame d of the reciprocating wirei stitching devices is shown particularly in Figs, 2', 3, and 4. a It is provided at opposite. edges with parallell bracket-slideways" d d2. These are in the form of grooves, preferably with enlarged ends, so that oil may be iilled i oo into the ends more orless to be taken up at each movement by the parts sliding therein.' y f The reciprocating frame of thevwire-stitching devices essentially comprises the round parallel bars-ff, the cross-'barsjfQ formed to re 1o 5 ceive said parallel bars and-.onA their under portions to fit and. move in the slideways d d2 of the bed. At one end f2 is a iix'ed cross-bar with apertures to receive the pms of the spools of wiresf. sent parallel fixed cross-bars at right angles to the parallel bars f f and through which said bars pass, the said cross-bars being pinned to the bars f f, and thus securely held, so

that the parts are obliged to move together.

h h represent movable cross -bars, and h2 a movable presser-bar, said bars being parallel with each other and with the bars g, g', and g? and at right` angles to the barsff, through which said bars f f pass. helical spring secured at one end to the bed and at the other end to the under side of a bar m.

Upon the left-hand end of the auxiliary shaft e thereis a bevel-gear b2, which meshes. 12 '5 with avbevel-gear b3 on a verticalshaft' b4 in bearings secured to the bed of themachine. At the upper end of this shaft b4 thereisa crank bf", (see Figs. 2 and 3,). and a link b is at'one'end secured to the free end of/rgov' sprocket .c3 to move the conveyer-chain c Fig. lion the dotted line of 7'5 Fig. 1 showsthe general inclination of the4 gr gli and y? I'Gple- 1,10'

h4 represents a.r2o

This is an idle shaft, upon the respective ends of which are cranks t, and links i2 are at one end connected to the cranksv i and at their other ends to one parallel bar f. By these devices--that is, by the bevel-gears b2 b3, shaft b, crank b5, and link b-a reciprocating movement is imparted to the wire stitching or stapling devices upon the bed-frame d, the series of fixed cross-bars and movable cross-bars and the parts associated therewith upon the parallel bars f f sliding across the bed in the slideways d d, these parts being compelled to move-in unison and with an even true reciprocation, because of the cranks fi and the links i2, which with thev shaft i engage and control the respective ends of the reciprocating frame and compel the even movement thereof, during which movement the slide-bars fj" inthe slide- Ways d d2 gather oil from the end pockets, so

as to insure the full lubrication of the slide-l Ways during the movement.

Upon the fixed cross-bar g there are series of straightening-rollers 2 2, between which the wires from the spools f3f4 pass and are straightened in their movement. One or more of these rollers is adjustable for increasing the tension or pressure'on the wire. This roller is illustrated in Figs. 9 and 10, in which 3 is the pin assing down into the cross-bar g and provldedwith a hub 4 and with a contracted neck between the hub andv the pin placed eccentric to the laxis of the pin. The hub 4 is provided with a handle 5, by which the hub, neck, and pin are turned Vinthe socket in the cross-bar g so as to bring the roller 2 nearer toor take the same farther from the rollers associated therewith, so as to vary the applied pressure. On the fast cross-bar g there are holdback gripping devices for the wire, each of which vcomprises an inclined face-block 6 anda straight face-block 7, the faces of which are separated a` distance agreeing substantially with the diameter of th roller 8. A coil-spring 9 has two free ends, one of. which is fastened to the inclined face-block 6 by a screw and the other to the bearing-pin of the roller 9, and the wire passes between the1 straight faceblock and the roller, and the function of the roller is to grip the wire against the flat face- 'block and prevent any return or back movement of t ewire which might o'ccur with the return movement of other parts hereinafter described. y

On the movable cross-bar h there are wiregripping devices substantially the same as those just described upon the cross-bar gthat is, there are inclined face-blocks l0, straight face-blocks 1 1 rollers 12, and springs,A

The shaft i is 13 with the wire passing between the straight face-blocks and the rollers, and the function of these latter devices is vto grip' the wire with a forward movement of the lmovable cross-bar h so as to com el the wires to feed with the cross-bar an Ato pull the same through between the straighteningr-ollers 2 and through between the straight faceblocks 7 and rollers 8. Upon the movable cross-bar h there are guide-blocks 14 for the wires and through which the wires pass, and

.these guide-blocks also serve as supports and y places of attachment for the plunger-bars n n.'

The movable cross-bar h is madey with offset ends, in whichare secured stems 15, threaded near their ends where they pass through the ends of the movable cross-bar h, and nuts 16 are upon the threaded ends of said'stems adapted for adjustment as hereinafter described. The fixed cross-bar g is provided with stems 17, which passthrough the movable cross-bar h/ and on which stems there are lock-nuts 18, the said stems and lock-nuts limitin the movement-in one direction of the mova le cross-bars h h.

I em loy two bell-crank levers k 7c. (See especia ly Figs. 3 and 4.) These levers are ivoted to the under side of the fixed crossar 'g, and to the short ends of said bell-crank levers are pivotally connected links Z Z, the other ends of Isaid links being pivotally connected to the under side of the movable cross-bar h. The long ends of the bellcrank levers 7c c are pivotally connected to a bar m beneath the movable cross-bar h', the right-hand end of which bar m is of increased width, (see Fig. 3,) and I provide a plate 19, secured to the bed-frame d of the machine and rovided with a roller 20, against which uring the movements of the devices the broadened yend of the bar m is adapted to strike and in its arrested position and with the reciprocatin movement of the arts hereinbefore descri ed to swing the bel -crank levers 7c 7c and impart a movement to the movable cross-bars 7L h longitudinally of the parallel bars ff and with said movement to draw along the wires by virtue of the grip of the rollers 2 a distance predetermined by the position occupied by the nuts 16 on the stems 15, the movement being shorter or longer, according to the position of the said nuts.

The plunger-bars n n, secured upon Vthe movable cross-bar h by the guide-blocks 14, pass through between guides 21 22 on the fixed cross-bar g. This fixed cross-bar g is grooved longitudinally to receive the cutter-bars o', upon Whichare adjustably ositioned cutters o 0, which can be set and lield in position by the clamping-screws, shown especially in connection therewith in Figs. 6 and 7. Pivotally'mounted upon the upper surface of the fixed cross-bar g/ are rocker- bars 02, 23 being the pivots ofthe lrocker-bars. These rocker-bars are of the peculiar form shown in Fig'. 3, with jaws to receive the pins 24 in the cutter-bars o, .said rocker-bars being connected for opposite movement by a link 25, whose ends are pivotally connected to said rocker-bars. The pin 23 of thev left-hand rocker-bar, as it ap# pears in Fig. 3, passes completely dwn 1o through the fixed cross-barvg, and on the lower end thereofthere is secured an arm 26, whose free'end bears against a portion of a bar.27, which isxed at a convenient pointv to the bed-frame d of the machine. Fig.

i5 -8 shows a portion of this bar 27, whicl'i'is provided with a notch and a recessed portion, the free end of the bar 26 traveling along the recessed portion with a part of the movement v off-the reciprocatingdevices and engaging zo the notch of said bar, so as to swingth'e cutter-bars o from the position of the cutterbar in'Fig. 7 lto the'position ofthe cutter-bar in 6,'and in so doing to cut off the wire to form the staple Vand simultaneously turn ver the cutend. of the wireY at right angles 'to the portion of the wire that isalready within the guide-blocks rrz. As the cutters o sever the wires and continue their movement they turn the ends cut 3o ofi" against the die-blocks r1", the same being at right angles, as just stated, to the portions of the wires that are already in the .guideblocks` r r2. These die-blocks 11 r (see es- )pecially Figs. 5 and 6) ar'e 'narrow and are 3 5 ada ted for vertical movement between# the gui e-blocks r r2 i'n'waysthat are formed in the fixed cross-bar g. -Tlie lower portions of these die-blocks 1* i" are reducedand are each rovided with a helical's'pring 28v 4o between isks 29 andy 30v see Fig. 5,) and the lower ends of said die-blocks are provided with an elongated 'slot receiving the' pins which connecty said die-blocksto the'-V cranks r3. These cranks raare on a shaft 0"4, 4S .the bearingsof which (seeFig. 5) ext d toward and are secured to the fixe-d. crossbar g. L At one end of the shaft l1A there is a crank-arm T5 and link r6, (seeFigs. 3 and 4,) the free end of the link being pivotally .connected to the movable cross-bar h', from which it will be apparent that when this crossbarhf is moved alongthe'parallel bars f f, as hereinbefore describedL that-the connection therewith of said link r". and crank-arm rf will rock the shaft v4, `swinging the crank 13' and drawing down'the die-blocks#| r. lThis movement is to be timed with the movement ofthe plunger-bars fri/ n', so that. after'tli'e wires are cut and the staplesV formed bybending the ends against said dieeblocks Vand the presser-bars bear 'against the ends of the v` staples to force the same intol the superintposed signaturesor sheets Vthat the diefblocks draw down as the presser-bars move forward,

the staples sliding up overtheinclined upper vable along the cross-bar t3 with' th with a roller 38, running on thev peribearing-'surface ofa cam 39, secure .onthe forming the essential functionof assisting in the staple is pushed for-ward.

Within or just beneath the movable crossbar h2 is placed abar s, provided'with notches ends? ofv the `dieblocks, said die-blocks per .j

to receive the rollers s, which rollers arepivoted to the said cross-bar h2, and I providev .dogs s2, also pivoted to the under side of the movable cross-bar h2' and coming between the facexof the bar s' opposite the notched face and the surface of the superimposed signatures or sheets as they rest in the guideway against a fence I providea post s-cl on the frame of the machine, against which with the reoiprocation of the parts the righthand'end of thebars strikes and which-when arrested ,is-moved `longitudinally `to a suffinotches receiving the rollers and bring the doing toswing the dogs s2. As' these dogs are'. swung with thetimed movement of the parts they come against the ends of the wire staples protrudingfrom the signatures of the 852.; cient extent to throw thevbar out of the.

`rollers onto the flat face of the bar and in so magazine and the movement of the dogs bends these protruding ends` down fiat and .tight against the outer surface of the outerf most signature of the magazine, clenchin-g the same firmly in position and in-so doing binding or wire-st1tching the magazine.

t t. are toggle-bars pivotally vconnected to the shaft t?, the ends' of which are in bearings on the cross slide-bar f. toggle-bars is .made to a toggleshaft 32 and shaft`f33 is in bearings in the movable-crossvbar h2, and to said shaft is connected a link 34, extending downward in the machine.

Thelend of` the link.34 connected "to "the in lthe frame of the machine. The upper ends of the cranks 35 are connected by a crossnotched to receive said cross-bar and is movcatory movement'of the parts.` n

The joint of the -the'freev ends of the toggle-bars are connected ato a shaft 33, to which they are keyed. This cranks 35,secui'ed-to ashaft 3 6 in bearings 'n e recipro Acrank 37, fast on the haft 36, (see 4,).l

hery or auxiliary shaft 'e ,and withfthe rotation of this` auxiliary shaft e and thecamf39 the..`

roller 38and crank 37 swing the-'shaft 36'and i2 bars h2. This movement fromfthe position of the partsshown in Figi 4 straightens-the r toggle-bars, and as one endof the toggle-bars is fastened to the cross-bars f it follows that the straightening of the toggles must move the cross-bar h2, and this movement is t0- ward the receptacle for the superimposed signatures or sheets to be bound, and the action of said parts is to come in contact with the back surface of the signatures or sheets and press the same tightly against the fence w, and this pressure is exerted coincident with the movement of forcing the wire staples I through the superimposed signatures or sheets, and the pressure is maintained in the timed movement of the parts until the righthand end of the bar s strikes the post s3 and swings the dogs s2 to overturn and clench the staples in position.'l The spring 31, at one end secured to the cross-bar h2 and at the other end to the bar s, serves to return the bar s to the initial position shown in Fig. 3 when this pressure is released and the dogs s2 are free therefrom.

I provide a threaded bar 40, at one end secured in a boss on the upper surface of one slide-bar f', and this threaded bar passes through the fixed cross-bar g2 and is provided with nuts 41 thereon at opposite sides of the cross-bar g2 in order that the adjustment of the wire-stitching devices may be provided to accommodate pamphlets or magazines of different thicknesses-that is, of different numbers of signatures and sheets-this adjustment being mainly apparent at the art shown particularly in Fig. 5, because W Aere the pamphlet or magazine is of a less number of sheets and the parts are adjusted the loose cross-bar h2 would then be brought nearer to the cross-bar g, thus reducing the space between the fence 'w and the adjacent and opposite' face of the cross-bar h2, and where a larger pamphlet is to be provided for the adjustment in the other direction will take the fence w away from the face of the cross-bar h2.

I provide and have shown in Figs. 2 and 4 a trough u, supported at one end by a bracket 42 on the side ofthe machine and at the other end by a post 43, secured to the Hoor. This trough in cross-sectin is of broadened -V form and is so laced that the superimposed signatures or sfieets as stitched by the reciprocating stitching mechanism are delivered directly from the machine into the trough. I have shown and prefer to employ a reciprocating finger-bar u and packer-plate fw* secured thereto, moving through. the trough and actuated by a link ua, at one end pivoted to the finger-bar andv at the other end to va flywheel u2 on the end of the axle-shaft e. This device with the movement of this auxiliary shaft feeds the pamphlets or magazines along through the trough tomake way for others that are coming from the stitching mechanism. A

I have shown in Figs. 3 and 17 studs 45 on the fixed cross-bar g in proximity to the series gaged by the conveyer-chain c with pins and moved along the signature -guiding trough c, their inclination being pro 4ressively increased toward the vertical, as s own in Figs.v l 1 to 1 5. As they reach the reciprocating Wire stitching .or stapling -devices they come into vertical position, as shown in Fig. 5, between vthe fence w and the movable cross-bar h2.V

Pressure is applied not only to hold but to consolidate t e signatures and sheets by the toggle-bars t t', which are in pairs and which are actuated, as hereinbefore described, by l the link 34 traveling along the cross-bar t3 at the upper ends of the cranks 35, the cranks being fast upon a shaft 36 and actuated by lthe crank 37, roller 38, and cam 39 upon the Z auxiliary shaft e.

This movement of the link 34 on the bar t3 permits of the reciprocation of the wire-stitching devices and at the same time makes possible the action of the mechanism-that is, the toggle bars-for gripping and at the same time holdingl the superimposed signatures and sheets. hereinbefore described, the wire-stitching devices are reciprocated by the auxiliary shaft e, by bevel-wheels revolving the shaft b4, and by the crank b5 and link bs, the movement being insured and steadied by the shaft t', cranks ft, and links i2, the feeding movement bein effected vby the bell-crank levers k k', whic are pivoted to the fixed cross-bar g, the links Z, connected to their short ends and pivoted to the movable cross-bar h', and the bar m, pivoted to the long ends of the bellcrank levers coming against the fixed stop or roller K20. y

for preventing back movement have also die-blocks r 1", the staples thereafter being4 forced by. said plunger-bars through the guide-blocks r r2 and through the superimposed signatures or sheets and clenched on the opposite side by the dogs s2 being actuated by the bar s when the same strikes the post sa. As the reciprocating wire-stitching devices come to the right hand of Fig. 3 and at each movement thereof in said direction a book is delivered into the trough u. These reciprocating devices are returned to an initial 'osition likewise by the shaft b4, crank b5, and ink b, and in said return movement the spring h4, acting upon the bar m, returns the bell-cranlr'llever devices (shown in Fig. 16) to i an initial position in which the wires while held by the gripping devices 6, 7, 8, and 9 are rengaged by the gripping devices 1011, 12, and 13 for a new hold on the wire, and the bar 27, acting upon the arm 26 and the parts hereinbefore described and connected there`- with, serves to return to an initial position the cutters ready to repeat the operations hereinbefore described. f

While I have shown in the drawing two lwires and devices acting thereon to form them into staples, it may be remarked that the devices of'my improvement are equallyv applicable for any number of associated devices, so that the signatures and sheets forming a book may he connected by two or more staples, as desired.

The fixed cross-bar g is recessed at us in its upper face (see Figs. 3, 4, and 17) to receive cotton waste and oil. The wires. as they -pass from the reelsf 3 f1 take u p su'licient oil A as they pass through or comein contact with the cotton-waste Vto lubricate the same and the parts through and between which the wires pass.
