Application January 24, 1950, Serial No.1405277;
(oran-1) This inventionL relates to form-binding machines useful for the mechanical aligning, straightening, stacking` and fasteningtogether Vsheets of paper and the like, Whereinpre-selected single sheets-roughly arranged into desired groups (such as bookletV signatures; business form sets, lined tablets, etc.) may be brought into alignment with each other and boundtogether bythe application of adhesives.
Particularly in that portion of thebindingart devoted to the binding together setsalternately comprisedA of' printedf forms interleaved with carbon paper, many devicesv have been developed in which printing, perforating, punching and other voperations required; on` theprinted formhave beer accomplished on continuous web presses, and later interleaved on machines known as Collatorsf `to provide the carbon paper interleaving. In machines of this type., the various parts of the Web are bound toeachother by the application of aV continuous strip ofy adhesive applied between each part by rotary applicators. Registration, or the accurate positioning of each sheet of such sets With each other sheet, Aisobtained by punchingaccurately spaced holes along the edges of the Webs during the printing operation, and later using these holes as feed-ing means in thecollating machines, to prevent slippage and mislocation ofthe sheetswithrespect to each other. These guide holes are trimmed off prior tothe final?" cut-oit of the web intosingle sets. The disadvantages of' this method. include the necessity of a large paper Wastage, the requirement of relatively large quantities of any given specification, the high cost or the equipment, the limitation of the number ofparts to a set ofthe stati'ons or backstand capacity of the collators, and the diiculties encountered because of variable stretches and shrinkages of the paper stock after being punched, often causingvthe guide holes to become unequally spaced' to prevent their proper functioning as registration feeding means-and other diiiiculties.
These difhculties, and particularly the high cost in time and material in the preparation of the various rolls or webs of material tobe collated and bound, have caused the unending search by printers and binders over many recent years for a simple and easy means. of binding such sets of forms` prepared by ordinary sheet printing methods.
Several! machines have been devised to aid the sheet method of collating and binding. One of these, of the conveyortype, provides stations or locations for individual hand feeding of'sheets vby operators to a conveyor belt requiring one 45` Claims.

apply adhesive to eachsheet between` the feediing stations. The Agreat*disadvantage of this method andi machine is that: the failure to feed by any operator, orv the misplacement 'of any sheet, causesl the: entire operation to cease until the. error is corrected.V
Another type, known as Spob-Grluers consists of' a table to which anl operator hand-feeds' individual sheets to which adhesive is applied to each sheet between the feedingoperations'A by a series of ngers containing the adhesive. Whirlethis type of device isy used for the bindingv ofsets of two to five sheets par-ts, therequirement of feeding eaclir sheet separately makes the operation relatively lslow and costly where av greater number of parts'is required.
A fourth method of binding sets in very common use is known as Edge-Padding. Forms tobe bound by this. method are pre-collated to the desired 'set, joggeel to register, trimmed to size, stacked a glu-ing rack," hand-painted with adhesive, dried andy later sliced into individual sets'.
It will be seen from the foregoing description that the steps inall of the methods in common use for collecting and binding Setsf Signatures, Pads and the like, consist of means to gather such: groups in desired rotationand register and causing their various parts tov adhere to each other by the application of adhesives. In the/sheetq methods'described, it has been necessary toA locate the sheets in a position of registry or alignment, sheet by sheet, and' to apply the adhesive as a subsequent operation. In some instances, such as edge-padding, several subsequent operations have-been necessary.
It is an object of my invention to provide an improved and simpliiied form-binding machine structurewhich maybe keconomically manu-iactured from comparatively inexpensive parts but which will be of sturdy construction and will be reliable and elcient in operation over long periods of' time andv will require little attention an adjustment.
Another obj ect of my invention is to provide a machine into which may be fed a group of loose, diiierent, roughly-gathered sheets comprising a multisheet form or set, which will align, insideglue and discharge a single bound set; and a related object is to make provision for said machine to press and Wipe the adhering edges when necessary andtoy align the finished individual Another object of my invention is to provide a form-binding machine equipped with means to accurately align roughly-gathered sets of sheets, from two to fifty or more, and automatically to present and feed to an adhesive supplying mechanism the proper edge and surface of the sheets for automatic application of adhesive.
Another object of my invention is to provide a machine equipped with means of applying vadhesive simultaneously to the leading edges and adjacent inner surfaces of all sheets of a set vor the like which it is desired to bind.
Another object of my invention is ltofprovide for the Vdelivery of aligned and bound sets in finished aligned groups. Y
Another object of my invention is to provide for the automatic binding of predetermined numbers of sheets of different weights or characteristics (such as carbon paper and printed forms) interleaved as desired, the adhesive being inside the bound edges of the sheets.
Another object of my invention is to provide a form-binding machine of the foregoing type with means to grip and remove the boundv form a or group of sheets from the adhesive applying means; and a related object is to provide additional means to 4press and wipe the edges of the bound sheets to remove adhesive which may be clinging to them. if;
A still further object is to provide in a machine of the foregoing kind means to clean o regularly and automatically the .pressing and wiping means.
Other objects and advantages will become apparent as the invention is described in connection with the acompanying drawings.
My invention lies in my discovery that when individual sheets such as for making up any desired set are caused to align themselves withf: each other by the vibrations or motion of the 4o edges against a stop plate coated with adhesive, in the course of this aligning movement their desired edge and surface portions adjacent to the edgebecome coated with the adhesive. Fur-if; thermoreit was discovered that in such cases f5 Where it is advisable for purposes of avoiding adherance between sets'or groups or for other reasons to pre-coat the adhesive material and merely reactivate it by a solvent, heat or pres-1 sure in the manner above-described, the same result could be accomplished. The experiments with the above combination demonstrate that adhesives, or adhesive-activating agents applied as described, may be made to cause the variousf."`
sheets in the set to adhere to each other and that the adherence will occur at an instant when the desired edge rof each sheet is inexact alignment with the corresponding edge of each other sheet, this being the desired relation. K From the above it will be seen and from the following description and drawings it will become clear that my inventionfprovides a means 'for theautomatic and simultaneous application' of the necessary adhesive, adhesive activator or sol-.; vent or the like, to all of the sheets to be bound G5 during the aligning process, whether the number 0f sheets be two or many more, and whether the sheets be the same or different in quality or size. In describing the invention for simplicity of expression I refer to glue and gluing but it will be understood that I include thereby other liquid'adhesives,v adhesive solvents and activators, whether or not heat and pressure are also required as in the case of some plastic substance.

The invention as illustrated is supported by a suitable frame work comprised of angle irons but any other suitable frame work may be employed.
Generally speaking, the invention comprises several related mechanisms. First, there is a table or support upon which are placed the sheets which will comprise the individual unit or form and which are to be glued together at one edge. On this tablerthe sheets to comprise the form are vibrated or moved rapidly to align them with one another and are presented to the mechanism forl 'applyingxglue orA other adhesive, adhesive: activator or solventl or the like.
The second portion of the invention therefore comprises. the gluing mechanism or assembly.
vThis comprises the applicator or glue plate 50 and associ-ated parts which are supported from Ythe vertical posts 30 and 34.
After the sheets comprising the form are caused to adhere at their edge portions they are grasped by the third portion ofthe machine comprising thetake-off mechanism designated generally by the letter T.
(See Figs. 1 and 13.) The take-off vmechanism presents the form to the fourth-portion of the machine comprisingI the wiping mechanism. The wiping mechanism is designated generally by the letter W. (See Figs. 1, 13 and for details, Figs. 15 110420.)
Allof the foregoingl generally-described portions of the invention are related functionally in the following way: The sheets comprising the form are caused to adhere by the gluing mechanism and then are taken by the take-off mechanism to be presented to the wiping mechanism which gently presses together the glued edges and wipes off the edge any adherent tiny globules of glue. Hence the machine does notv complete its operations on the form; until after the wiping mechanism has functioned. Following that the form is discharged.
With the foregoing in mind the details of the several portions of the machine willnow be described.
The vibrating or jogging table 40 may be supported by means of S springs 42 from a stationary platform 4| located between and supported by the vertical posts 30., 3|, 33 andli. Structure of this sort is described and illustrated in my copending application S. N. 587,554, led April 10, 1945, entitled Jogging Machine. It will be understood, however, that. the present invention is not limited to the use of such jogging or vibrating means as is illustrated and describedinv that application, such structure being mentioned merely as an example of a suitable sort of vibrating means. Any means which brings the edges into alignment by sliding movement of the sheets over one another can be used.
Upon the fixed platform 4|. is mounted the driving motor 43 which through a pulley and vbelt drive operates the vibrating. means designated."-
generally by thev numeral 40 in Fig. 11. (See also Fig. 1.) Upon the vibrating table 4G may conveniently be arranged a rail or guiding edge 45 so that as the sheets of paper which are to comprise the individual form are tossed upon thel table 40, one edge of such sheets-will work its way over with abutment against and be guided by the railv 4,5. The table 410- is preferably tilted at a convenient angle so as to cause. the vibrating sheets to move toward the left-hand edge of the table as viewed in Fig. 1. /As the sheets are caused to move in this manner by the'vibration of the table, the forward' edge ofthe sheets (the left-.edge in Fig. 1') will abut a glueplate 50 which is located and, moves adjacent theforward edge of the` jogl.
ging table 4D.. In this manner the sheets are lined; up and ready for the application of thev adhesive, adhesive activator or solvent or the like to their forwardedges in the manner now to be f described.
The gluing assembly Referring to the form ofthe invention illustrated in Figs. 1 2,3, 4 and 6,'a gluev plate, preferably of metal,y ismounted insuch a way as to be lupon ahorizontal shaft' 69.
moved in 'a plane. perpendicular to. the; jogging table, 4'adjacent the tables forward edge.` The glueplate is pivotally supported on .upwardlyextending rods 5| and 52 which.; are f slidably mounted in guide. blocks or bearings..53V and 54 (Fig. 6) mounted upon the verticalposts 3l)` and 34. TheV glue plate. is caused to rise andlfallrby substantially vertical movement of the rods. 5|, 52. For this purpose on the top endof the. right rod. 5| (Fig. 2) a rectangular block55is secured. From the side of this block nearest the glue plate 5H there 'extends in a radial direction a headed pin 5S. To receive the headed pin 56 there is mounted fixedly upon the glue plate 50 adjacent the right end thereof a block 51 having an inverted U-shaped recess opening into the bottom thereof, the recess being undercut for the-head ofthe pin 56. By the described connectionY the glue -plate is mounted at its Vright end` pivotally and removably upon the rod 5|. l
At the left end the glue plate is mounted upon the rod 52 by a diiTerent pivotal connection. A block 58 is secured upon the rod 52 near its upper end and has a radiaLrecess to receive a pin 59 laterally extending from a short link 6|) which is secured to a block 5| xedly mounted upon the left' end of the glue plate 50. In order to guide the upper end of the rod 52 a breroller S3 is mounted axially upon the top rod. The roller may roll over the surface of a block '64 secured to the-upper end: of the glue plate 5B. It isy desirable that the roller be provided because of relative motion between the plate and the rod 52 as willY now appear from the following description-of the mechanism-for raisingand lowering theI glue plate.
Gn the mid-portion of the rod 5| there is radjustably secured another block 66 yto the inner side of which the upper end of a link 671` is pivotally connected. The'lower end of the'lin'k 61 has/apivotal connection with a crank 68 mounted The sha-ft -S'EI is driven by'a motorl (see Figs. 1 and 7) mounted upon a horizontal frame bar between the vertical frame posts 3'6 and 3|. A belt ll connects a' pulley on theY drive shaft of the motor-lil withv another pulley of a reduction `gear box 12. A drive gear T3 on the opposite side Yof a boX from the'pul'ley meshes with a similar spur gear 'M mounted upon the shaft 5S. In this manner the shaft Eiland the crank 63 are rotated.
In a similar manner at the. opposite end yof the shaft 'Se there is mounted a crank 'l5 having a pin connection'at its endwith thelower end' of a link bar 16. The upper end ofthe link bar l5 is connected pivotally with a blockl 'il adjustably mounted upon the mid-portion of the rod 52. V
The crank arm l5 islonger than the crank arm '53 with the result that when the shaft 69' rotates the left end (referring to Fig. 2) of the glue plate moves higher or has a longer path than the righthand. By reason of the unequal movement of the ends of the glue plate, the bottomv of the plate lies in a horizontal plane when; the plate is at its lowest point.; and when it is` at its lowest point the slot 82 is in register with the forward edges of the jogging table dal. When the plate is at its lowest point the bottom edge of ther glueplater is withina trough 3B, containing liquid adhesive or adhesive activator or the like and supported upon a horizontal frame member 8| connected between the vertical frame posts 39 and. 34. The lower edge of the glue plate, which lies within the trough is preferably serrated so that the liquid adhering thereto will drop off/at the. points' of as it rises.
'the serrations rather than running down toward the lowerend ofthe blade as the blade tilts From the foregoing it may now be seen that `as ythe immersed lower edge ofthe glue blade Eil rises,
it fwill rub over the forward edges of the sheets comprising the individual form F which are tov be glued. The glue plate tilts as it rises becausev of .the unequal movement of the ends of the plate asabove described. When the glue plate is in its highest position, its lower edge is parallel with the edge of the jogging table.
Y In order to remove or discharge the glued form, YI provide in the glue plate a slot 82.
This slot is at such an angle to the horizontal that the lower edge of the slot is in alignment with the edge of they vibrating table when or at approximately the` time that the glue blade is at its lowest point. Thus, the form F may move through the slot 82 under'the force of gravity after being glued. It may then be collected in a container or removed by hand but I prefer to remove it mechanically and present the glued edge to wiping means as will presently be described. With some glues and .under some circumstances it may possibly be unnecessary to wipe olf the glued edge since ordinarily only a minute and very small number of droplets of glue will occasionally adhere to the glued edge of the form; but for most purposes it is essential that every trace of glue be removed.
From the foregoing it will be apparent that the unequal or tilting movement of the rising blade is necessary practically becauserof the tilted condition of the vibrating table 40 when considered against the necessity for having the glue trough in a horizontal position. Since for practical purposes it is desirable only to have perhaps about aninch of the lower end of the glue blade immersed in the glue trough, elevation of the blade without. tilting is impractical if not inoperative because that would result in part of the edge of the forminot being glued.
In Figs. 8-12 I have shown another form of gluing mechanism. Here the jogging table and jogging mechanism and the mechanism for raisi ing and lowering the glue plate are as before.
However, the glue plate differs from the previously-described form in that a larger slot or opening is provided, the purpose of which will be explained.
Instead of the forward edge of the form abutting the glue plate during the jogging and alignment of the sheets comprising the form F, afgate or bar 8571s provided closely adjacent the forward edge of the jogging table'to hold the form upon the table during its alignment. The gate 85 is held slidably on extensions 39a: and 34.7: of the posts 30, 34 by bolts 86 and 81 extending laterally therefrom and passing through parallel short slots 88 adjacent the opposite ends of the gate 85. To fractionally hold the gate 85 in whatever position it is moved into, springs 89 are coiled about the shanks of the bolts and press the bar against the surface of the extension 38:1: and 34:13.
In the lower position of the gate 85 (wherein the top of the slots rest upon the bolts) the lower -edge' of the gate is adjacent but below the forward edge of the jogging table so that the gate holds the forms thereon. In the upper raised Yposition of the gate wherein the lower end of theA slots is next to the Shanks of the bolts 86, there is' a free space between the bottom edge of the gate 85 and the top of the jogging table 40'. Hence it is possible for the form to slide under the gate.
Since the elevation of the gate 85 leaves a gap between the surface of the glue plate and the forward edges of the jogging-table into which the form might slip, I provided a U-bentwire or equivalent means, depending from thelower edge of the gate 85 and having itsY mid-portion parallel to and in alignment with the edge of the jogging table when the gate 85 is elevated. Thus this wire will fill the gap between the surface of the glue plate and the jogging table and enable the form F to move into the opening 93 in the glue plate 50 at the proper time and in the desired manner.
In order to elevate the gate at the proper time, I provide a pin 9| on the lower portion of the glue plate and extending laterally so as to engage the bottom surface of the gate 85. This pin is so located that it will elevate the gate at or immediately prior to the time the glue-covered zone across the bottom edge of the glue plate comes into alignment with the top of the jogging table. YThus as the gate is elevated the forward edges of the sheets of the form move over into engagement with that portion of` the glue plate bearing the glue and the gluing takes place in the same manner as in the previously-described form.
As the operating mechanism for the glue plate continues, it starts to move the glue plate downwardly; but the gate remains elevated because of Y lposition to engage the top edge of the gate 85 as the glue plate descends. Thus the gate'is lowered into position for the sheets of the next form to ,be placed upon the jogging table and the operation completed.
The take-o1? mechanism In order to take away the glued form F asit passes through the slot 82 in the-glue blade`5|l and to present the glued edge to wiping means, I provide mechanism including gripping jaws to grasp the form just back of the glued edge so that the glued edge is free and can be presented to wiping means as will now be described. As the edge of the glued form passes through the slot 82, it is gripped between a pair of relatively movable jaws |00 and I0 extending transversely from side to side of the machine. The lower jaw |90 comprises a rod, either round or flat-topped, which may be rubber-covered or not, with its ends xedly mounted in oscillating parallel metal arms |82, |03 locatedon opposite sides of the machine. These arms are pivotally mounted at their bottom ends in such a way as to cause their oscillation in unison as will presently be described. The upper ends ofthe bars |02, |83 are bent as may be seen best in Fig. 6 to incline tle jawsfso as to vbe at Athe same angle as the .glue plate .slot 8:2 and jogging table edge when the jaws vrare .adjacent the slot and .ready .to grasp the edge of the form issuing therethrough.
'The upper jaws |10 .preferably comprise a sqfuanefrod'whose `ends are slidably mounted with.- in yslots |05 in the upper ends of thenoscillating arms |02, |03, the slots being just -above'fthe mounting Aof the lower jaw. AIn order `to move the upper jaw relative to fthe 'lower jaw, cast metal 'links ||2 Yare Iconnected with the ends of the upper jaw I I0 which `extends through the slot |105. VTo the :lower ends -of the links ||2` are pivotally connected one end of crank arms-|10 (as-may best be seen `in Fig. 5), the lother -end of the-crank 1N, being mounted rigidly upon a rock shaft H5 extending transversely .of the vmachine below the jaw members and journal'led rockably Within'fthe -arms |02, |03. In order to rock the shafti-IS, -a rocker arm ||.6 is secured upon the rocks/haft H5 extending radially theretromfhavingitsfree end Vconnected -pivotally to a longitudinally reciprocating connector bar f||"| which entends downwardly and atfits lower end l'has a slotted connection with a shaft |50. (See YFig. 13s) 'Ilhis reciprocating bar is not caused to move Albythe shaft |50 .but is -simply'guided Ithereby.
. In .order to move the-connector bar |121 inthe direction kof 'its length, a lroller ||18 bis provided extending from the side thereof .near its lower end imposition .to engage `with the upper surface of a-rockingllever |19. The rocking :lever vis .pivotailiy mounted upon a stationary stand at one 1end and at .its -otherpend `has a cam roller :|22 adapted to follow .a rotary cam |24 mounted upona transverse cam shaft |25.
,As the cam V|124 rotates the rocking lever |19 rocks up and down and .thus the connecting bar is Icaused tto move lengthwise up and down. i.
To assist gravity, a spring |2| may .be anchored at itsrfupperend to the connector bar and .at itsilower end v toene .of the fixed bearing supports |:2.2.:fo r the shaft |50. By lthis mechanismsthe upper jaw I l0 is caused to move toward and away from the lower jaw |100.
In .order to -stop .at just the .right place `the sliding of the for-m F :through the jaws L00, ||.0 after application of glue, .and in order .that `when the jaws `grip the :form .the gripping will take place at precisely .the right point, Iiproviide .curved stop fingers (see Figs. .5 and `l2) .of which .two or more may ,be mounted -on an oscillating shaft |3| pivotally mounted ,and .extending between the .arms |02, lr03. The location vof these fingers in position to stop the 'form 'F is illustrated in Fig. 12.
ATo move the fingers out of the way .as -the take-.off mechanism swings left v(Figs. 1 and -13), I provide (see Fig. 5) on an .extension of 'one end of Ythe ,shaft 13| -a crank 'arm |32 vwhich is rocked vby `a vconnecting link |33 .attached pivotal'ly at one of its ends to the crank. Near the other end of :the link |33 theffree-end of .an idling crank arm l|34 is pivotally connected, rthe lidling crank being pivotally Amounted Vona 2Din 2| 35 @prgjecting from a 4lateral Aboss. 43.6 4on the oscillating arm L02. of Athe llink |33 is a .cam roller |311 riding .onuthe underside of a stationary cam jtrack or -cambar |38 extending alongside of themachine -fromethe top of .the ventical fpostw;|'.32 to a'pointJ-bel'ow .the level of .the .glue reservoir v'(seeFigs. 1, 13 and 125)..'

1 from -theoperative position of Fig. 12 to the ini active position of Fig. 5, and vice versa on return movement.
As the take-off mechanism moves from the gluing mechanism toward the wiping mechanism, the angle of the paper relative to the horizontal changes. At the start, Athe angle is sub stantially the same as that of the jogging table, ordinarily about 30; at the wiping mechanism the angle is about 60.
in order to support the form as it moves from the gluing mechanism to the wiping mechanism there are provided a series of spaced parallel thin supporting rods, |00, extending lengthwise of the machine from a transversely located shaft -|4| pivotally mounted in ,bracket .L44 on thewiping mechanism frame. At each end of the shaft |44| there 1is `mounted a vcra-nk arm |42A urged-in a counter-clockwise direction *by a coiled tension spring |03 anchored to the frame of the wiping mechanism. The effort of the spring |43 exerted through the crank arm |40 upon the shaft "MI tends to move `the 'supporting rods |40 ina c ounter-clockwise direction. 'This tendency yis resistedV by the rods coming into engagement` With theV undersideof the lower jaw member |00 of the take-off Jmechanism. `As thev take-'offmechanism moves from the gluing mechanismtoward the *wiping mechanism, the rods" 440 arethus urged -to move 2in a counter-clockwise direction from the position substantially as illustrated in full lineSin'Fg.

For the purpose of holding the cam roller |52 against the periphery of its cam I5|, a tension spring |55 is connected with the cam arm |59 and is anchored to the frame of the machine.
As will hereinafter be more fully described, the wiping mechanism is driven from the driving means mounted upon the base plate B through the agency of a shaft |51 in alignment with the shaft |41, there being a bevel gear |58 upon the end of the shaft |51 meshing with the bevel gear |45. Upon the opposite end of the shaft |51 is a sprocket wheel connected by a chain |58 with a sprocket |59 on a common shaft |59s with a spur gear |98, to drive the wiping mechanism as will more fully appear. The shaft |51 is journalledV in bearings |510. mounted upon the base plate B. v
The wiping mechanism Mounted on top of the frame posts 32, 35 are end supporting brackets of substantially triangular shape, |60, |6|. Running transversely across the machine Vand supported in these brackets |60, |6| are parallel rods |63 and |64. The rod |63 is at a higher elevation and spaced lengthwise of the machine from the rod |64. Slidably mounted upon the rods |63, |64 are similar carriages/designated generally by the numerals |65, |85, since these carriages are alike except that the wiper elements which they carry face oppositely. Hence only one will need to be described. These carriages comprise a bottom plate |66 upon which are molded bosses |61 which are bored to receive the rods |63, |64, but one boss may have an open side, if desired, to facilitate assembly. A top plateV |68 isA secured to the carriage by screws |69 entering into the body of the bosses so that the top plate |68 is spaced from the bottom plate |66.'V Extending from the back side of the carriages |65, |85 are -bolts |65b and |8517 (see Fig. 20) for engagement by operating levers as will now be described.
In order to driveV the sliding carriages |65, |85, as lheretofore indicated, the chain |58 engages with a sprocket wheel |59 rotatably mounted upon a transverse upwardly-inclined supporting bar |9| extending between the supporting frame posts 32 and 35. The large spur gear |90, driven by sprocket wheel |59, meshes with a likel large spur gear |92 on a shaft |929` also mounted in the crossbar |9|.. Extending laterally from the face of the spur gears |90, |92 at a point near theirY peripheries are two bolts |93, the shanks of which extend through and slide within slots |94 of Vactuating bar or lever members |95, |96 pivoted at their lower ends upon spaced pins |91, |98 respectively, mounted in a lower cross bar |99 between frame posts 32, 35. At their upper ends the actuating bars |95, |96 have slots through which pass the pins |6517 and |8511y respectively. It will thus be seen that as the spur gears |90, |92 are caused to rotate in opposite directions, the actuating bars |95, |96 will move toward and away from each other causing the carriages |65, |85 to slide along the guide bars |63, |64 toward and away from each other.
The sliding carriages |65, |85 are inclined due to the location'of the guide bars |63, |64, so that the carriages face upwardly at an angle, as illustrated in Fig..1'1. Mounted in the upper face or top plate of the carriages is a pivotY pin such as 2|0 which is screwedj therein and has a smooth shank 'beneath a' hexagonal headY upon vwhich shankk are `pvotallyy mountedone on top of the other, a pair of similar wiper-supporting members 2|2, 2 I4. As illustratedl in Fig. 18 the member 2|2 is on top and the member 2|4 is beneath it. The shape of the wiper members may be seen best in Fig. 18 and may generally be described as comprising a substantially circular body portion from which projects, in a radial direction, an enlargement or arm 2 |211., the similar arm 2|4a of the member 2|4 extending in a diametrically opposite direction. Laterally extending downwardly from the arms 2|2a and 2|4a. are small abutment pins 2|2p and 2|4p in position to engage wiper-closing actuator bar members 222, 224 which are xedly mounted upon brackets220, 22| Which in turn are mounted on the guide rods |63 and |64. The closing bars 222, 224 are so placed as to cause clockwise and counter-clockwise rotation of the wiper carriers 2|4, 2|2 respectively (into the position A0f Fig. 18) when the pins 2 |411', 2 |2p engage the ends of closing bars.
Mounted upon an enlargement extending approximately at right angles to the arms 2|2a, 2|4a are the wiper elements 2|3, 2|5 which are preferably small metal blocks set into the carriers 2|2, 2| 4, at right angles thereto and having either rubber or hard tips thereon. Reversely bent arms 2|2, 2|4x extend from the enlarge- .ments 2|2, 2|4 and are connected by a tension spring 2|6 which is adapted to move across the axis of the pivot 2|0 as the members 2|2, 2|4 are rotated between closed position (Fig. 18) and open position (Fig. 15). Thus rotational movement is assisted by the spring 2|6 as the line of action of the spring crosses over the axis of the pivotV pin 2|0; and holds the two members 2|2, 2|4 with their wipers 2|3, 2|5 either closed (in engagement with opposite sides of the form F, Fig. 18) or open (as in Fig. 15).
The rotational movements of the wiper carriers in the carriage is in the opposite direction to that of the elements in the carriage |65 but the movement of the wiper elements 223, 225 together to grip the form F is the same in both carriages.
As the carriages |65, |85 move away from each other, they approach wiper-opening bar members 232, 234 and 23'2, 234' mounted upon brackets 236, 236' of any suitable form which are adjustably positioned at the desired places toward the opposite ends of the guide bars |63, |64.
The form is held stationary between the jaw members |00, |0 of the take-olf mechanism during movement of the wipers toward the sides of the machine. Hence the wipers perform a wiping action over the entire forward or glued edge of the form, the one pair of wipers 2|3, 2|5 wiping from about the middle to the left edge and the other pair of wipers 223, 225 wiping from the middle to the left. The slight pressure exerted by the Wiper elements upon the edge of the form as they are wiping across it, tends to improve the adhesion of the several sheets of the form while at the same time wiping off minute globules of glue which maybe presenten the edge.
From the foregoing it may be understood that as the carriages move toward the sides of the machine, the pins, for example, 2 |2p, 2|4p of the geraete 13 ing their travel so ythat Ythe form is therefore entirely free, for removal from the machine.
Since there may be a tendency for the glue to accumulate upon the wiper elements 2 |3, 2 l5, 223, 22 5, I provide between the pairs of opening bars 232,- 234 and 232', 234,vwipercleaning members mounted upon .brackets 236, 230. The cleaning members may be twisted metal bars 240 with sponge rubber tips 24|. This wiper cleaner is .so positioned that the tips 24| will tend to separate the wiper members 2|3, 2|.5 or 223, 2.25 as they come into contact with said tips, thus starting the opening movement of theA wiper elements which is continued by the engagement .of the opening b ars 232, 234,'for example, with lthe pins 2|2p, 2|4p. Since the opening movement ofthe Wiper carriers is accompanied by passage of the line of action of the spring 2|6 across the axis of the pivot 2|0, wiper carriers are held open (Fig. 15) by the action of the spring. p
In order t make certain that there may not be a portion at the center of the glued edge which is not wiped, I provide for overlapping of the paths of the wipers at the middle of the edge of the form. I locate the fixed `pivots |91, |08 of the actuating arms |95, |96 differently relatively to the pivots of the driving or spur gears |90, |92. By so locating these pivots one of these arms |95, |96 maybe caused to move the carriage which itactuates further than the "other, It makes no difference which of these carriages is moved further than the other as long as one carriage is carried a su'icient distance so that its wiper elements overlap the path of the wiper elements of -the other carriage. By so relating the gears |90, |92 relatively to one another that the radii, on which the sliding pins |93 are located, do not ever align but so that one is slightly in advance of the other, it is possible to cause one set of the wipers to engage the glued edge of the form F and start its return movement just prior to the engagement of the other wipers with the form.
Operation Assuming the gate 85 has just been lowered by the pin 92 on the glue plate, the glue plate will then have its bottom in the glue trough 80.' At this time the loosely-gathered sheets of the form F are dropped on the table 40 and by reason of its 'jogging action `are aligned against the guide rail and the gate 85. The cranks 68, on shaft'f) which control the rise and fall of the glue plate being in the arc at the bottom of their rotation give an interval when there is no significant amount of vertical movement of the plate while the gate is down. During this interval and also while the plate rises 4until its pin 9| elevates the gate, the aligning of the sheets takes place.
When the gate rises the sheets move forward into edge contact with the glue plate and almost immediately (or simultaneously, if desired) their edges'are rubbed with glue adhering to the 'bottom part of the blade. y
' vThe-gate 85 remains up'by reason of the frictional supports atlits'ends, illustrated in Fig. 10.
When the glue plate is descending and the gate is'still up (before the pin 92 hits the gate), the opening 93 in the plate permits the passage therethrough of the glued sheets of the form. At this stage the take-ofi mechanism is adjacent the glue plate (see Fig. 12) ready to receive the glued form issuing through the opening 93. As the gluededge ofthe form F moves through lthe opening 93, it passes through the open jaws |00, lfof the `take-'off mechanism and comes Ato rest against the stopngers |30.' Immediately-.thereupon the upper jaw |'|0 moves down toward the lower jaw clamping the form adjacent its edge.
in the take-off mechanism by reason of the downward -action of operating rod ,through .the action of cam |24 and cam rod ||9 as illustrated in Figs. 1, 5, 13. Immediately thereafter the ro- `tation of cam shaft |25 and its cam |5| causes rocking of the shaft and arms |02, |03 thereon through the action of the cam follower |52 and its arm |53. (See Figs. 1 and 14.)- Therocking of the arms |02, |03 is in a counterclockwise direction as the apparatus is viewed in Fig.. 1,. thus causing the take-off mechanism to move from the gluing mechanism over to the wiping mechanism W.
During this movement the cam roller |31 on link |33 of the take-off mechanism rolls upon the undersurface of thestationary cam rollery |38 causing the link |33 and crank arm |32 to rock the shaft |3| (see Fig. 5) to move vthestopiingers |30 out of the path of the `form F.
Also during the aforesaid movement ofthe take-off mechanism the supporting bars |40 upon which the form F is held, rock in a counterclockwise direction from approximately the full line to the dotted lineposition of Fig.,13 by reason of the ybias of spring |43 on the shaft |4| lupon.
travel, wiper-closing bars |22, |24 abut vthe rightv ends of the pins Yon theY wiper carriers (corre-v sponding to pins 2|'2p and 21417, Fig. 18). This abutment causes rotation in .a counter-clockwise direction of the wiper 223 which thereupon .closes with -a snap motion due to the action of the over! At the .time -or immediately upon the carriagev starting its movement toward the .outside of the machine, the wipers l2|.3, 215 on the left hand carriage |05 close upon lthe glued edge. .of the paper. Their path of wiping over the left half of the glued edge overlaps to a slight degreev the path of the right hand wipers v2.23,22.5so as.
to leave no intermediate unwiped area.
The wipers now being open, the-formgcan be removed by hand or by automatic mechanism as desired, or can .be allowed to drop into a basket or Ycontainer by gravity as the for-m slides voii .the supporting rods-|40 from the position illustrated in Fig. 13. been adjacent the wiping mechanism and during the operation of the wiping mechanism the gluing` mechanism has been operating through its-cycle as previously described. The rotation of the cam |5| will now cause the take-off mechanism to "return to ,the position adjacent the gluing mechanism wherein it will be ready to repeat, the operation just described. By tha-time the While the .take-off fmechanismjfha-s.

It is beueved that the. operation ofthe gluing.'
mechanism illustrated in Figs. 1 to 6 will beV clear fromthe description of the operation of the gluing mechanism of Figs. 8, 9 and 10. In the form of Figs. l tov6, the absence of-thegate 85 does not v alect fundamentallyL 'the essential functionlof the gluing. In the form of Figs. l to 6 the sheets of the form F are aligned and'maintainedn alignment. by their abutment against the face ofthe glue blade and by the guide rail on the table until the time that the bottom part of theV glue blade which carries the glue comes in contact With-the' forward'edge of the form. FromV that point the gluing action is precisely as in the form of Figs. 8, 9 and l0. The functioningof the'take-off mechanism is the same in each case. 'v
From-the foregoing it may be understood that the invention can be employed with sheets having a thin strip of dry glue or other inactiveadhesive onan-edge. The glue or adhesive'may be acti` vated bythe gluelblade dipping into a solvent or activator which by the mechanism described is thus introduced at the aligned edges of the sheets bearing the adhesive strip; with the result that adhesion may take place at the moment of exact alignment, as before.
'If thermo-plastic or thermal setting adhesive is used, the heat or pressure or both can be applied by the take-oft' mechanism jaws, in which event they may be heated electrically from within by hot Ywire heating elements (not visible) or otherwise suitably connected by electric wires 190W,` I IDW at the ends of the jaws |00, III) to a source of electric current.
' In some cases the cutting of the sheets which are to make up the form may not have been accurate so that the edge of the papers may have a slight curvature. To take care of that co-ndition I provide on the back of the gluing blade a. tensioning arrangement comprising a bar 50a. running across the mid-portion of the back of the blade.Y At each end it is screwed or bolted tothe blade but spaced therefrom by washers. Fixedly'mounted or welded on the plate near the mid-portion of the bar'there are one or two spaced bolts llb. The end of each screw passes through a bore in the bar. Through the bar transverse to each bore a slot is cut to receive a round thumb. Thus by turning the nut 501L so that it presses against one side or the other of the slot, the bladev may be compelled to take a slight concave or convex bend Yso as to conform exactly with the edges of the sheets comprlsing the form.
