CARLOS 'nonm, or women, ma roan, meson or one-ms mo .rosnrn A. warm AND onnnanr mo JOHN mum, or Locxron'r, new. max,

Be it known that I, Camel-Tonia, a citizen of the United States, residing at Lockort, in the county of Niagara and Statebf New York, have mvented anew and useful Improvement in Looping-Machines, of which the following is a specification.

This invention relates to a machine for applying loops to blanks, pamphlets, almanacs' &c., whereby the latter may be hung up and is a modification of the machine for which I obtained Letters Patent of the United States No. 593,218 on November 9, 1897.

In my former machine the blanks or pamphlets were fed automatically one ata time from a stack or pile to the devices which applied the loops-thereto and after theloops were thus applied the blanks or pamphlets were again stacked in. piles. By automatically feeding and stacking the pamphlets, the capacity of this machine was very great but the cost thereof restricted its use to printing or binding establishments having a very large output.

The object of the present invention is to provide .a machine of ,this character which applies the loops efliciently to the blanks or pamphlets but which requires the blanks to be fed by hand, anddoes not automatically stack the same, thus materially simplifying the construction of the machine and reducing the cost thereof, and placing the same within the reach of the smaller printers or binders.

In the accompanying drawings consisting of 4 sheets: Figure 1 IS a top plan view of my improved looping machine, the parts be-. ing shown in position for receiving a blank. Fig. 2 is a fragmentary topplan vlew thereof, partly in section, showing the position of the parts after the blank has been perforatedand carried to the loop applying mechanism.

7 To allwlwm it may concern." Fig. 11. Fig. 13 is a detached elevation of one of the cutter blades whereby the twine is severed.

Similar letters of reference indicate corresponding parts throughout the several views.

In its general organization, this machine consists of a main frame, means for perforatin the blank, means for supplying twine for ta loop and drawing the same through the perforation of the blank, means for t ing a knot in the loop and severing the same rom the suppl twine, and means which grip'the blank an carry the same successively to the perforating, tw ne applying and knotting devices.

The main frame of the machine may be of an suitable construction to support the movab e parts of this machine, that shown in the drawlngs consisting of front and rear longitudinal. walls, plates or bars A A, cross pieces a a connecting the front and rear walls at or near opposite ends thereof, and legs or. standards B B, upon which thewalls or plates are secured.

The blank gripping and carrying meclr anism may e variously constructed, that shown in the drawings being constructed as follows; C C represent a pair of upright rock arms which are arranged side by side wall and connected at their lower ends by a hub 0 which is pivoted by means of a horizontal longitudinal stud c on the main frame, so that these arms can swing in a vertical plane transversely of the machine.

These carrying armsare moved forwardlyby means of a cam 0 arranged on a horizontal main shaft D and engaging with a roller 03 which is mounted on arms al projecting forwardly from the' hub 0 of the carrying arms while the backward movement of. the arms is effected by means of a spring (I connected with the roller arm 05 and the rear wall of the frame, as shown in Figs. 1, 2 and 5. This cam is so constructed that it holds the blank carrier at rest momentarily in its rearmost position to permit of placing a blank in proper position thereon and perforatin the same, then moves the carrier fol-war ly and comes to rest momentarily in position to permit the twine to be drawn through the perforation of the blank. then tory to receiving another blank. At their upper ends the carrier arms are connected by a horizontal longitudinal bar E the front side of which serves as a gage against which the back longitudinal edge of the blank to be looped is placed in order to register the same properly relatively to the devices which apply the loop thereto. In front of this gage bar the carrier arms are provided with a supporting plate 6 which is curved concentrically with the pivot of said arms. This plate in addition to supporting the blank which is placed upon the same also serves as the lower aw of a gripper whereby the brlank is held in place on the carrier while being operated upon. The blank is held against this lower jaw by two upper jaws e e which are arranged side by side above the lower jaw and project through openings e formed in the adjacent part of the gage bar E. e represents a horizontal rock shaft or hub connecting the rear ends of the upper gripper jaws and pivoted horizontally on lugs projecting rearwardly from the gage bar so that the front ends of the upper gripper jaws move in a vertical plane toward and from the lower jaw. This rock shaft is turned in the direction for yieldingly holding the upper gripper jaws in contact with the lower jaw by means of a spring 6 surrounding said shaft and connected atone end with one of the upper jaws while its opposite end is connected with the adjacent part of the blank carrier, as represented in Figs. 1 and 6.

The upper gripper jaws are lifted from the lower jaw into an inoperative position to permit of introducing a blank between the jaws and discharging the same therefrom. The mechanism for this purpose, shown in Figs. 1 2 and 6, consists ofan elbow-shaped rock lever F pivoted on lugs projecting rearwardly from the front wallof the frame, a cam f arranged on the main shaft and engaging with a roller f on the upwardly projecting front arm of the elbow lever and an upright shifting or connecting rod f engaging its upper end with one of the up er gripper aws and pivotally connected zit its lower end with therear end of the rear arm of said elbow lever F. The

across or close to the axis of the carrier arms at the inner end of the stud a, so that the shifting rod f turns practically concentric with the carrying arms and permits of opening and closing the upper gripper jaws without interfering with the operating mechanism thereof. The gripper opening cam f is so constructed that it raises the upper gripper jaws from the lower gripper jaws whi e the carrier is in its rearmost position and ready to receive a blank, then the up er ripper jaws are permitted to descen un er the action of the spring 6'' for clamping the blank on the carrier. Theupper ripper jaws remain in this position and ho d the blank firmly in place during nearly the entire forward movement of the carrier during which time the blank is presented successively to the erforatmg, threading and knotting mechanism. When the carrier nearly reaches its foremost position the upper gripper jaws are elevated andrelease the blank which latter is thrown forwardly and then remain in this elevated position during the entire backward movement of the carrier and also during the period of restof the carrier upon reaching its rearmost position, which permits the next blank to be placed between the jaws of the carrier.

The device whereby the blank is perforated is best shown in Figs. 1, 2, 8, and 11 and is constructed as follows: 9 9 represent the cooperating punch and die of the perforator which are arranged adjacent to the left hand side of the blank carrier and a short distance forward of the registering face of the gage bar when the carrier is in its rearmost position. The die of the per-. forator preferably consists of a steel sleeve or bushing which is placed vertically in a seat formed in a bracket G projecting forwardly from the rear frame wall and the punch is arranged above this die and movable vertically into and out of the same. The punch is secured to a forwardly projecting arm 9 arranged at the upper end of a vertlcally movable slide g which is guided in a way g formed on the rear frame wall. The reciprocating movement of the punch carrying slide is produced by means of an elbow-shaped 'rock lever g pivoted on the front frame wall and having a horizontal bifurcated lower rear arm the members of which carry a roller 9 and one of which members is connected with the lower end of the punch slide and an upright bifurcated front arm which carries a roller 9 and cams g, g mounted onthe main shaft and engaging respectively with the rear and front rollers of the rock lever 9 The perforator cams 9 g are so constructed that when the salient part of one engages its respective roller for moving the elbow lever fere with the looping operation if the downin one direction, the other cam presents its" receding portion to its roller so as to avoid interference of these parts. By this means the punch is positively lowered and raised, whereby sticking of the punch in the blank after perforating the same is prevented, which would be liable to occur and interward or effective stroke of the punch were produced by a cam and the upward or re-' turn stroke were produced bya spring.

In order to prevent the blank after being perforated from rising with the punch, a stripping finger ye is provided. This finger has an opening through which the punch passes and is secured to the adjacent stationary part of the machinein such a position that its underside is arranged flush with or slightly below the lower end of the punch when the: latter is in its elevated position, as

shown in Fig. 8. If the blank tends to stick to the punch the same will be stripped off from the punch by the finger against which the blank is lifted and thus prevented from following the. punch to its uppermost position. After the blank has been thus perforated the same is moved-forward by the carrier one step andpresented to the threading devices which draw the loop twine through the perforation of the blank.

The mechanism whereby the twine is supplied and drawnthrough the perforation of the blank is best shown in Figs. 1, 8, 11 and 12 and is constructed as follows: H H

represent two rotary twine feeding disks or disks and serve as the bottom of a twine groove which is formed between the marginal portions of: these disks. These disks are arranged immediately in. front of the the front disk, so that its lower portion is. arranged comparatively close to thelowerportion of the front disk while its upper portion is separated considerable distance from the corresponding portion of the front disk. For this purpose, the rear twine feeding disk is journaled on a stationary bush--- ing' Ti sue-rounding the countershaft k and having its'aixis: oblique to the axis of said shaftgas shown in Fig. 12. The rear disk is compelled to turn with the front disk by means of pins h formed on the latter projecting into recesses in the former, as shown in Figs. 11 and 12. The twine IS supf-plied from any suitable source and directed part of by a guide It into the upperwide the groove hctween the feeding dis {5 and thence passes.rearwardly, downwardly and forwardly through the groove between the .marginal portions of these disks. As the latter rotate the tilted position of the rear disk relatively to the front disk causes" all of the peripheral parts of the disks to successively approach each other asthey movedownwardly and forwardly to the underside .of these disks, and then. separate again as they move upwardly and rearward'ly toward the upper part of these disks. By' this means the groove on the top of the disksis left wide open for the introduction of the twine and on the lower side thereof the groove is contracted causing the twine to be gripped between the opposing lower faces of the disks, whereb v all the parts of the disks are engaged with successive portions of the twine for feeding the same forward and then released therefrom to. permit of util iz ing' the twine thus supplied for drawing through the perforation of the blank and forming a loop thereon. h It" represent corresponding radial notches formed in the periphery of the twine feeding disks and extending across the flange between .the same so as to expose that portion of the twine extending from one side of the notches to the other. The main shaft and the parts mounted thereon make one complete rotation during each cycle of operations of the machine.v The twine feeding disks are caused to make one. rotation during each rotation of the main shaft by means of an angular connecting rod or bar h having its ends connected with ranks h 71. on themain shaft and the counter-shaft, while its intermediate portion is connected with aguide crank it on the main -frame, as shown in Fig. 9.

I represents a needle which engages with that portion of the twine which is exposed by' thenotches of the feeding disks and draws the advancing end of the twine out of engagement with the feeding disks and through the perforation of the blank. This needle is arranged below the "feeding disks and is" movable vertically in} a guide opening z formed in the bracket below the path The mechanism for raising of the blanks.

and lowering the needle shown in Figs. 1, Y

8 and 11, consists of a vertically movable cylindricalholder or slide '5 guided in the opening 2' and carryingthe needle at its upper end, anelbow-shaped rock lever 2' pivoted on lugs arranged on the front frame wall? and having its rear arm connected with the'lower' end of said holder, a cam 71 arranged on the main shaft and engaging with: a; roller 21 on the-depending front arm ofthe rock lever z" for lowering the needle, and a spring a" interposed-between the front arm of the rock leveri" and the main frame and operating to turn the rock lever in the direction for raising the needle holder. The parts are so timed that while the notches of the twine feedin disks are on the lower side thereof, the nee 1e rises and passes through the perforation of the blank which latter is in this position at this time and then engages its upper bevel end with the exposed part of the twine and deflects the same until the book "of the needle is above the twine when.

the latter again springs back to its normal pcsition underneath the hook of the needle. The needle after reaching its uppermost position immediately descends into the guide opening 21 and its hook draws the twine out of engagement from the feeding disks, thence through the opening'of the blank andthen into the up er portion of the guideway z' in the bracket or the needle holder. In its elevated position the hook of the needle projects laterally so as to properly deflect the twine-in the feeding disks during its upward stroke and engage with the twine during its downward stroke. After the twine has been thus drawn through'the perforation of the blank, the latter is carried forwardly another step from the threading position to the position shown inFig. 11 in which it remains at rest a sufiicient time to permit the knotting' device to 7 effect its operations. While the blank is thus carried forwardly by the gripper, the twine is drawn partly off from the hook of the needle and partly off from the feeding disks and a forwardly extending loop is formed which extends from the threading device to the blank. The two strands of this loop in being drawn sharply over that portion of the bracket G between the needle guide opening 2' and the rear side of the bracket would be apt to out each other if permitted to rest one upon the other. This undesirable relation of the two strands would occur if-the hook of the needle were permitted to remain continuously in the laterally projecting position which it must necessarily occupy to engage the twine in the feeding disks. Means are therefore providedv for causing the two forwardly orin the direction which theblank moves, as shown in Fig. 11, whereb the loose end'of the twine is deflected su ficiently so that the other strand of the loop which is still connected with the supply twine" will 'not rest upon the same. Themeans shown in thedrawing for turning the the bills.

needle and cause its hook to project laterally in anelevated position but to pro ect forwardly in its depressed position conslsts of a pin 7' secured to the bracket and proknotter mechanism which are formed respectively on the inner and outer telescoping knotter shafts K K". These shafts are arranged horizontally and lengthwise of the machine so that the two strands of the loop'upon being carried forwardly by the blank are laid into the bight or mouth of both bills, as shown in Fig. 2. After the two twine strands of the loop have been thus laid into the mouth of said knotter bills, the latter begin a forward rotation and at the a same time those portions of the twine strands between the knotter bills and the blank are pushed underneath theknotter bills by means of a hook shaped deflector L. This deflector hook is arranged on the back side of the strands of twine while the same are laid into the mouth of the knotter bills, as shown in Fig. 2. Vhile the knotter bills are effecting the first portion of their forward rotary movement and the deflector hook is moved forwardly, that portion of the twine strands between the knotter bills and the blank is deflected laterally and underneath the knotter bills, as shown inFig. 3, in order to enable the points of the knotter bills to make a turn or twist in the strands. After the front ends of the knotter bills have passed around the strands and have nearly made a complete turn or twist in the same, the bills are separated by moving the inner bill and its shaft backwardly, thereby causing the knotter bills during the last portion of their forward rotary movement to straddle the twine strands immediately in rear ofthetwist, as shown in Fig. 4. The knotter bills having now been placed astride of the two strands in the manner described,

the bills are again closed by moving the inner bill forwardl together with its shaft,

whereby the tralling end of both twine strands of the loop are firmly grasped by After the trailing ends of 7 the twine strands have been thus gripped, said strands are severed in rear of the twist, and then the knotter bills are rotated in a reverse direction causing the severed ends of thetwo strands to be drawn backwardly teases through the twist the strand, producing. a knot which reliably connects the same an completes the loop. While the knotter bills are effectingthe last portion oftheirreturn movement, the carrier begins its forward movement so asto draw on the loop and cause the knot to be tightened. This pull of the blank upon the loop while its ends are still held by the knotter billsis only momentary as the knotter bills are separated immediately after such pull in order to release the loop. The mechanism foi' thus rotating or oscillating the outer shaft of the knotter is bestshown in .Fig. 7 and consists of a gear pinion m which is secured to the outer knotter shaft between the bearings in which the same is journaled,ia gea-r segment M meshing with said pinion,'a rock arm m carrying said segment and pivoted on.

the rear wall of the main frame, a spring m operating to turn said gear segment in the direction for moving the knotter bills backwardly, and a cam wa secured to the main shaft and engaging with a roller m. on the segment carrying arm 'for turning the latter in the direction for moving the knotter bills forwardl The inner shaft of the knotter is com el ed to turn with the outer shaft but is ree to move len"thwis'e thereof by means of one or more sp ines n. The len thwise movement of the inner knotter sha t is effectedby means of a rock lever N pivoted at its lower end on the front wall of the frame and having a fork at its upper end which engages with a grooved collar n? at the rear end of the inner knotter shaft, a cam n arranged on the main shaft and-engaging with a roller n onthe knotter rock lever or moving the inner knotter shaft in the direction for opening the knotter bills, and a spring a connecting the said rock lever with a stationary part of the machineand o 'eratingtoturn the same in the direction or movin the inner knotter shaft forwardly and-c osing the'bills;

In additionto movin .the deflector hook laterally relatively to t e direction of the twine loop, it is also desirable to move the same to some extent across the'end of the knotter bills in order to reliably retain the twine in engagement with the underside of said bills while producing a twist in the same. For this purpose the deflector hook is mounted on a plate or'bar 0 which is pivoted at opposite ends on a pair of like cranks 0 0 which arejournaled vertically in bearings arranged on the bracket G; One

' of these cranks, preferably the outermost one p is provided with an actuating arm 0- which is connected by a link or'rod 0 with theupp'e'r end of a vertically'swingmg rock arm or'lever 0 which is pivoted at itsj lower e frame. This lip-Q right rockdev'er, as shown inFig; 8,.is moved end on the rear wall 0ft rearward-1y in the direction for eausin the deflectorfhook to draw the strandso the twineloop laterally aroundthe knotter bills by means of a cam P arranged on the main blade is secured to the front end of a verti-' cally. swinging rock arm Q, which is secured at its" rear end to a horizontal rock shaft 9 journale'd in the adjacent part of the bracket G. The rock arm Q, is arranged on one side of the path of the twine and its blade pro j-ects laterally from the front end of said arm so that upon rocking this arm the blade will cross said path. The rock shaft g is oscillated by means of a link or connecting rod R connected at its upper end with a rearwardly projecting rock arm r on the rock shaft 9 an elbow-shaped rock lever S pivoted on the front wall of the main frame and havin its rear ,arrn- ,connected with the lower. en of the link R, cam 3 arranged on the main shaft and engagin with a roller 8 on the front arm of the el owleverS, and a spring s. which moves saidelbow lever in a direction opposite to that which it receives from the cam 8 I y ile the loop of twine is being drawn from the threading device over the knotter and the deflector,- it is also drawn over the upper blade of the cutter; Afterthe twine has been thus drawn into a loop, the upper cutter rises and deflects the twine above-the same out of the path of theupper cutter blade by means of the beveled upper side t of this blade. .When this cutter reaches the upperlimit' of its stroke; its lower cutting -edge clears the twine loopand the latter by its resilience springs underneath this edge so that the upper cutter blade which immediately thereafter again descends, presses the trailingiends of the two loop strands against; the lower cutter blade. The two blades remain in this relative position for gripping the two twine strands between them without however cutting the strands'during the time that the knotter bills and the defiector are moving forwardly for producin a twist in the loop and obtaining contro offthe rear end of the loop strands, but after the knotter bills have obtained control of the loop strahds'in rear of the twist'then the. upper cutter blade completes its downward movement'a'iid seversithetwo strands so as train the operation of tying the knot to lib completed and the blank with theloop attached thereto to be carried away, In order to permit of thus grasping and holding the strands of the loop temporarily between the cutter blades without cutting them, the upper cutter blade is yieldingly connect ed with its actuating mechanism. This yielding connection is preferably effected by connectingthe upper end of the link or connectingrod R with the rock arm 1- in the following manner :-U represents a hollow coupling block which is pivoted to the rear end of the rock arm 2' by a pin u passing through a longitudinal slot 14 in the block. V represents a head formed at the upper end of the connecting rod R and arranged in said block. This head is yieldingly held against a shoulder 1) at the lower end of the coupling blocks a spring w is arranged on the block and bears at its ends against the pivot pin a and head V as shown in Fig. 10. The operation of the cutter cam s and the spring a is such that the upper cutter blade is quickly raised past the twine and then lowered upon the twine which is between the same and the lower cutter, in which last-mentioned position the spring a is slightly strained so as to produce a yielding pressure of the upper blade against the twine resting upon the I lower blade but when the loop strands are within the control of the knotter bills the continued upward movement of the connecting rod R under the action of the cutter cam s exhausts the tension of the spring W and produces practically a rigid connection 2 between the same and the upper cutter blade.

whereby the last portion 'of the downward movement of the upper cutter blade is effected positively and results in severing the twine strands between the blades.

In order to. avoid clogging the machine with waste twine when the same is running without blanks being fed to the same, a clearing hook or finger a; is provided on the lower plate or gripper of the carrier which takes the place of a blank and thus removes the twine loops formed by the machine.

In the drawings the working parts of the machine are exposed but in practice these parts are inclosed by a curved cover and an end gage 1 is mounted on the cover to facilitate registering the blanks as shown by dotted lines y in Fig. 6.

In my present machine the loops can be applied to the blank at any part along its edge rendering it possible to apply hanging loops at the center of show cards and the like in which respect this machine is superior to thatshown in my former patent which latter was capable of applying loops only to the corners ofthe blanks.

If desired, the main shaft may be driven directly from the source of power but it is preferable to drive the same from a driving shaft Z journaled lengthwise in the lower part of the frame andprovided at one endwith a driving pulley Z and at its opposite end with a pinion Z which meshes with .a gear wheel Z on the adjacent end of the main shaft.
