To all whom "it lnca/y concern:

Be it known that I, HERBERT G. LA SoR, a citizen of the United States, residing at New Haven, county of New Haven, and have invented certain new and useful Improvementsin Insetting Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the saine.

This invention relates to certain improvements in insetting mechanism.

It is desirable to use in connection with sheet folding machines constructions by which-one part-of the product of such mafolding will be placed within inset within the other ypartfofthe product. ==It has been proposed the successive pass between a pair nd :after the sheet has partly ment of oneof the rolls, the' moving roll acting to comb the ply next it away from the :other ply so as to open the sheet. When s-thus opened, the roll which had sheet thus opened was dropped onto a supof air was directed other reasons, this the air `blast lat the time it 'againstffthe folded sheet.

port. -Successive sheets were treated in the same manner, so as to assemble them'into a pack and after the desired number of sheets had beenaccumulated, the pack was discharged. The mechanism for accomplishing the insetting operation thus described was complicated and expensive, and for that and mechanism has not gone into general use, Another proposed method of accomplishing this insetting o aeration-involved the use of an air blast. n the mechanism referred to, the folded sheetswere dropped into a receiver, after which a blast against the edge of'the sheets, the idea being to thus force the sheets open. The use'of this air blast required that the-'sheets have a fold at right angles to what may be termed the final fold line, and further that this right angle fold face is delivered A This is so, because-should. it beattempted to direct an air blastfalgtinst the edges of a folded'prod- Auctvwhichpresented a nume-er of plies, the

Y air-'wouldabe liable to enter between .any of., shown, las theyv may be the plies, and therefore, might not separate the sheets into two\parts on the fold line. as required.' Further, it has been found that this air blast mechanism is not suitable for light paper or for sheets of large dimensions, and it also requires considerable time-for its operation, so that the output of the folding mechanism is reduced.

The present invention has forV its object to produce an improved insetting mechanism for folding machines which is positive in its action, thus being adapted for paper of all grades and sizes, is simple in its -construction, and can be operated at a rate of speed which adapts it for use on rapidly operating folding machines.

A further object. of the invention is to produce an improved insetting mechanism which operates against the'iat side of a folded product while ported on its fold line to shift the position 'of that. part of the product which lies on one side of the fold line with respect to that part of the product lying on the other side of the fold line, so that the mechanism is adapted to the opening of productsV folded in any way.

With these and other objects in view, the invention consists in certain constructions. and in -certain parts, improvements and combinations as will be hereinafter fully described 'and thenspecifically pointed out in the claims hereunto appended. f

Referring to the drawings---Figure 14 is a side elevation of one embodiment of the improved insetting mechanism, certain parts of the construction being shown in section. Fig. 2 is a front elevation of the construction shown in Fig. 1, certain parts.L being broken away and bei'ng shown in section. Figs. 3, 4, 5 and 6 are detailed views-,onI an enlarged scale, illustrating successive posidifferent stages of Figs. 7 and 8 are detail views also .on an enlarged scale of the construction.4

the product is sup-` illustrating a modified form It will be understood that the improved' insetting mechanism forms apart of onwill be applied to a folding machine. The frame of this machine is indicated at1, butthe folding elements of themachine are vnot of any 'suitablede- 95 .tions of the sheet opening mechanism 'during the insetting operation. i

scription. 'A pair of fold laying rolls, such ras are usually employed in such machines, are, however, illustrated at 2.

In machines constructed in accordancev with the invention, a support will be provided for, the folded sheet which is to be opened and into which the entire sheet is to be inset Z While the construction of this support may be varied, in the best constructions the support will operate to support the sheet on its fold line. In the particular construction illustrated, this support for the fold line of the sheet consists of a -plate 3, this plate being made movable so as to permit the discharge of the sheets after the insetting operation. While this plate may be mounted and supported in any desired manner, in the particular machine shown, nit is carried on brackets 4 which may be fast to the acker plate 5 where such plate, Vas is usua ,f is employed. 1n the-best constructions, furthermore, ai back support for the sheet will be employed which should be arranged so that the sheet as it rests on lthe fold line support 3 before'referred to may stand atan angle to the vertical. While the construction of this back support may be widely varied, it may conveniently consist of a plate provided with supporting ears 7 which embrace a rod 8 extending across the machine from 'side to side.

The sheetvopene'r employedmay be varied in construction and may be mounted and operated in various ways. In the particular construction illustrated in Figs. l to 6, this opener comprises a 'pair of rolls 9, each of these rolls being mounted in a fork 10, the stein 11 of which enters a socket formed in a lever 12. Provision maybe made for permitting the roll to yield after it has been, by mechanism which will be hereinafter described, brought into contact with the paper and this may best be eiiec'ted by l`a suitable spring.'y In the particular construction illustrated, this spring, marked 13, is located in the socket of the lever 12 and' behind the stem 11, provision being made for permitting the stem toanove, thus'placing thespring under compression, by slotting the stem, as shown at 14, the stem being held in the lever 12 by means of a pin 15 which passes through the slot 14.

As yhas been indicated, the operating?` Vmechanism for the opener may be varie widely in its construction. In Figs. 1 to 6,

this operating mechanism includes a carrier in the form of a square rocking bar 16, this bar being trunnioned, as indicated at 17, in

l'suitable lbearings in the machine frame.

This carrier 16 is provided with a pair of hangers 18 which serve to support a shaft 19. This shaft 19, in the particular machine shown in Figs. 1 lto 6, is surrounded by a long sleeve 20, this .sleeve being clamped from one side Aof the on the shaiby'nieans of a friction collar 21 of 'lsual construction. Depending from the sl eve 20 are a pair of arms 22, these arms icing secured to the sleeve by means of a split hub 23 of the usual type. These arms 22 serve to support the levers 12 which carry the opener rolls 9, the levers being pivoted on studs 24 carried bythe arms.- In the particular construction illustrated in Figs. 1 to 6, the ends of these levers 12 have pivoted to them ,links 25,'the pivots which connect the links and levers being marked 26. The other ends of these links 25 are pivoted at 27 to studs 28, these studs being provided with reduced threaded. ends 29 which are screwed into the shaft 19 before referredto. The sleeve 20 is provided with slots, indicated at 30,'to permit the sleeve and shaft to have independent movements as will be hereinafter described.

The mechanism so far described is first given a movement which is, in edect, a positioning movement by which the parts are brought into position Sto enable -the movenient-s of the opener to begin. This may be eiected in various ways, it being understood, of course, that the operating means willV vary in accordance with the particular mechanism in whichthe invent-ion is embodied. 1n the construction shown in Figs. 1 to 6, the end of the shaft 19 is provided ,with a slotted arm 31 to which is pivoted a connecting rod 32. The connection between the arm and the rod is effected, as is usual, by a bolt 33, this bolt being adjustable in the slot of the arm. At its other end, this connecting rod,

32 is pivoted to an arm 34, which is fast on a rock-shaft 35 mounted lin suitable bearings in the frame. This rock-shaft 35 has eX- tending from -it an operating arm 36 to which 1s pivoted, at 37, a cam rod 38. This cam rod is slotted at its outer end to embrace a ycam shaft 39 and is provided with a roll 40 working in a, cam 41 mounted on the shaift. With the mechanism so far deuscribed, it will be understood that the cam,

through the connectionsdescribed, will' rock the square carrier' bar 16 `and the parts mounted thereon.

Suitable devices which may be varied' Iwidely in construction are provided for defining the limits of this positioning movementof the bar 16 and the parts carried thereby. In the particular construction illustrated, the bar carries a pair of arms 42, these arms being tied together b a cross bar 43 which is adjustably connect to the arms by means of bolts 44. One of these arms 42 is provided with a pin 45, over which takes the. hooked end of a rod 46. This rod is threaded at its outer end and passes through a boss 47 pivoted on a lever 48, this lever being swung on a stud 49 projecting inward frame. The rod 46 is provided with two knurled nuts 50,l these nutsv being located on opposite sldes of the boss 47. It is apparentthat the limit of, movement given to the square bar v16 depends on the amount of movement which the lever 48 has. In the particular construction shown in Figs. l to 6, the amount of movement -of this lever 48 is controlled from the able bearings in the machine frame. This.

sov

packenplatefthe lower end of. this lever beT ing connected to-the packer plate by means" rock-shaft has an operating arm 61 to which is connected acam rod 62, the outer end of this rod embracing the cam-shaft 39 before referredgto and carrying acam roll 63 working in ajcam groove in a cam located just behind the cam 41 before described.,

In the particular folding mechanism which has been selected to illustrate the invention, two sheets are forwarded through the fold laying rolls simultaneously. It belng assumed that the machine is beginning .plate,. now takes place, this plate being trated. The position of the various parts its operation one of these sheets drops onto the supporting plate 3 and the other sheet drops on ,a supporting plate 64 which is located on-the left hand side of the machine as is lshown in Fig. 2. The movement of the various mechanisms, including the packer moved back, and the sheet which is resting in the plate 3 drops through onto the receiving table 65and goes to waste. The sheet which is resting on -the plate 64 is then caught between a pair of suitably operated rollers 66-67 and transferred from the plate 64 to the plate 3. The mechanism by whichthese rolls 66 and- 67 are operated is Yno part of the present invention and a description of the means for operating them would in no way conduce to an understanding of this invention. The operating mechanism for these rolls is, therefore, not illusofthe mechanism at the time the waste sheet and the subsequent inset product are being discharged from the plate 3 onto the receiving table 65 is indicated in Fig. 6. As the packer plate carrying the fold line supportizg plate 3 starts forward, the shaft 35 is Yrocked by its cam and cam rod. This,

through the connecting `rod 32 and the arm 33, causes the carrier-bar 16 to rock, moving the'sheet'opener mechanism toward the back supporting plate 6. The rocking movement of the b ar will be due not only to the connections from the shaft 35, however, but also to the pull exerted on the rod 46 by the packer plate which is movi-ng forward at this time. This movement of the bar 16 continues until` the packer plate reaches vlthe end of its vforward movement'. During `the time the. packer plate is moving the arm 48 is swinging onits stud 49. When the packer plate comes to rest, however, the movement of the har is. stopped through the agency of the rod 46 and the arm 42. The inward limit of'this movement which has heretofore been referred to as the positioning movement can be closely determined by the adjustment of the knurled nuts 50 on the bar 46. After the positioning movement has ceased, however, the shaft 35 continues itsl movement and this continued movement causes the shaft 19 to turn in its bearings. The movement of the shaft 19 causes the sleeve 20 which is frictioned to it to also turn, and this swings the arms 22 from the position shown in Fig. 3 to the posit-ion shown in Fig. 4. The extent of this movement of the arms should be accurately cletermined, 'and mechanism which may' be varied Widely in its construction isl provided for this purpose.

As shown in Figs. 1 to 6, the sleeve carries a stop block 68, this block having a split hub 69 which embraces the sleeve and is secured thereto by a bolt 70. This stop block coperates with a set screw 71 which is tapped through a plate 72 carried on .one of the brackets 1.8 before referred to as supporting the shaft 19. The screw is or may be locked in position by means of a lock nut 73. A stop plate 74 also mounted on a hanger 18 is provided which limits the movementof the sleeve in the opposite direction.

the opener rolls with the paper may be varied. i

The movement of the arms 22 from the position shown in Fig. 3 to the position shown in Fig. 4 brings the opener rolls 9 into contact with the folded sheet which as before described has been transferred from the plate 64 to the plate 3. Although the sleeve and arms have been brought to a stop by the stop block and the stop screw 71 as before describel, the shaft 19 continues its movement. This movement rocks the stud 2S from the positionshown in Fig. 4 to the position shown in Fig. 5 which movement through the link 25 rocks the lever arms 12 from the position shown in Fig. 4 to the position shown in Fig. 5. This movement `of the arms causes the rolls 9 to comb the outer ply of the folded sheet down and bends it out from the position shown in Fig. 4 to -'the position shown in Fig. 5, thus opening the sheet. While these sheet opening operations have been going By adjusting the position of the ,stop block 68 the point of engagement of on, a second pair of sheets, in the operation y of the machine shown, is coming through the fold laying rolls, and as the sheet on the plate 3 is opened, the sheet above it is dropped into it, thus being inset therein.

The opening mechanism through the various agencies described is now swung back into the position shown in Fig. 6, the

. packer plate at the same time retreating and sheet would be shifted under the action of the rolls. To prevent this, a sheety controller may be employed. While this controller may be varied in its construction, as shown, it comprises two shoes 7 5,-each of these shoes being mounted on the pivot 24 which supports the levers 12 on the arms 22. These shoes are or may be connected by hooks 76 to the bar 43 before described as connecting the arms 42. These hooks may be pivoted to the shoes -75 by pivots 77. As the arms 22 swing in from the position shown in Fig.

v'3 to the position shown in Fig. 4, the shoes 7 5 dropinto the position shown in Fig. 4 and prevent any outward movement of the sheet under the operation of the combing rolls at the fold line, as is clearly indicated in Fig. 5. It is apparent that by adjusting the position of the bar 43 on the arms 42 the amount of drop of the controller shoes may be adjusted. As the Acombing rolls move down from the position shown in Fig. 4 to that shown in Fig.l 5, the distance between the center on which the roll carrying levers swing and the plate 6 decreases owing to the angular position of the plate. The springs 13 before referred to, however, prevent the sheet from being nipped too severely between the rolls and the plate, these springs permitting the rolls to move backward.

Referring to the modification illustrated in Figs. 7 and 8, `the rolls 2, theA fold line supporting plate 3, the back supporting plate 6 and the squared carrier bar 16 and the arms 42 and the cross bar 43 are all constructed and arranged as in the construction just described. In this construction, the positioning movement of the mechanism is determined, as. in the prior constructiom/ by 4a rod 46 which hooks over a pin 45on the arm p 442, and itmay be connected to the packer -a shaft 83. This sisting of two combing rolls 84, these rolls being mounted on hubs which'are pinned or otherwise secured to the shaft. The outer end of this shaft 83 is provided with a ratchet wheel 86 with which coperates a spring pawl 87 this pawl being pivoted on a pawl carrying arm 88, the hub 89 of which is loosely mounted on the shaft. 83.

with a. stop 91 and also with a pin 92. A"'

pull spring 93 is connected to this pin and to a pin 94 on the pawl carrying arm 88,. The arms 80 and 81 are provided with rearl are pivoted the controller shoes 75 referred to in the preceding construction, the pivots of these shoes being marked 96. These shoes, as in the preceding construction, may be connected to the bar 43 vby hooks 76.

In the operation of this modification, as the packer plate starts to move forward, the rod 46 exerts a pull onthe arm 42. At the same time, the connecting rod` 32 exerts a pull on the pawl carrying arm 88, this arm 88 being connected to .the arm 82 by the spring 93. The' result is that under the in-y fluence of both the rods 46 and 32, the entire opening` mechanism moves forward, getting,

yasit has been heretofore referred to, its positioninpl movement. This movement stops just before the opener rolls 84 reach the paper, owing to the fact that the movement of the packer plate stops and therefore prevents any further movement oflthe arms 42. The rod 32, however, continues to move and under the influence of the spring 93 swings the arms 81 and 82 and the shaft 83 forward until therolls strike 'the paper. After this happens, the rod 32 continues its movement,

. but the shaft 83 can no longer-move toward the paper. lThe continued movement'of the rod 32, therefore,l operates to cause the pawl 87 operating on the ratchet 86 to turn the rolls, thus combing down the outer ply of the paper; When the combing movement is completed, the pawl carrying arm moves back until its upper. end strilres'the stop` 91, after which the entire opening mechanism swings back, the carrier bar 16 rocking in the reverse direction. In the modification just described, Fig. y2' illustrates the position gf the parts ju'st after the combing action is efmn.

tThroughout this specification, reference' has been made to the outer ply of the folded product. This term wil be under-- stood to mean that part of the product which lies on that side ofthe foldline which" -ward projections 95 and to these projections is next the Opening mechanism whether this i consists of a singleor a number of thicknesses ofpaper.
