FOLDING-MACHINE.

SPECIFICATION forming part of Letters Iatent No. 506,448, dated October 10, 1893.

Application filed July 6, 1891; Serial No. 398,534. (No model.)

To all whom it may concern.-

Be it known that I, WALTER SCOTT, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, haveinvented certain new and useful Improvements in Folding-Machines, of which the following is a specification.

My invention relates to paper folding machines, and consists of combinations of de' vices hereinafter described and more particularly pointed out in the claims concluding this specification.

In the accompanying drawings forming part ofthis specification, Figure 1 is an end elevation looking to the right in Fig. 2. Fig. 2 is a side elevation looking to the left in Fig. 1. Figs. 3 and 4 illustrate certain parts more in detail. Fig. 5 is a cross-section of the guide friction-fingers used to keep the sheets taut; full lines indicatingthe positions of the parts as the sheets enter between the fingers, and the broken lines showing the positions when the 'be fixed in the position shown in Fig. 1, (that is, separated from jaw 22 by a small open, space or groove, the lower edges of the two fingers grip the sheets, the same being exaggerated for clearness sake. Fig. 6 is a crosssection of Fig. 3 showing the arrangement of the parts, and Fig. 7 is a plan of the feeding tapes, paster and lifting rollers. v v

The printed sheets may be fed in by hand, or fed direct from a printing machine, such as thatshown, or from other machines, or they may be fed by other means.

In the construction shown, the sheets are perfected by the type cylinder T and impression cylinder I; the grippers 10 open, and throw-offs 11 direct the sheets onto guides 12, whence they are taken by tapes 13, 14, running about pulleys or rollers 15, 16, respectively. Tapes 14 carry the sheets under guide rods 17 which are supported in any suitable way, as by the bar 18 from which the stops 19 depend. Or the bars 17 may be supported in the frame work and have the stops 19 adjustably secured to them by set screws or otherwise.

I sometimes use a suitable device to apply paste to a central margin of the sheet. The device shown consists of a fountain 20 from which the-wheel 21, journaled in the sides of the fountain, takes paste and applies it to a central margin as the sheet is -run along over the same. Other paste supplying means may be used in lieu of the ouejde's'cribed. The

. a central margin.

next step is the cutting of the sheet S along For this purpose, 1 cmploy a reciprocating head provided with jaws for holding sheets while being cut and for holding the edges of the sheets after they are severed. Oo-acting with said head and jaws is a knife or cutter working between two yielding cushions whereby. the sheets are first clamped,then cut,and the edges grasped by the jaws or grippers, the knife simultane ously being withdrawn. In Fig. 1, I show a head H having two jaws 22, 23, of which I prefer to have one, as 22, fixed, and the other, as 23, movable. I accordingly show the jaw 23 as pivoted to the head H, it being forced vtoward and from jaw 22 by suitable means.

In the operation of this construction, the jaws 22, 23 are separated at the time the sheet is cut into two sheets as shown in Fig. 1, by dotted lines, and come together to grasp the upturned edges of such two sheets.

Instead ofbeing movable, the jaw 23 may being in the same horizontal leveL) and have a series of notches 24 cut throughit. A shaft 25, journaled in the head H, is provided with a series of grippers or jaws 26, one for each I notch 24. The grippers 26 are preferably narrower than the notches, and also do not extend downward to the plane of the lower edge of jaw 23. Shaft'25 has an arm 27 at one end by means of which it is operated at proper times, as hereinafter described. The jaw 23, when movable, may be carried by shaft and be operated thereby.

The shaft 25 is journaled in the ends of the head H, as at 28. One or more coiled springs 29,fast at one end to the head H and at the other end to the shaft 25 or to a collar 30 held in place thereon by a set screw 31, act to hold the grippers normally in notches 24. The arm 27 may have roller 32 on it to reduce friction in the operation of the machine.

The knife 42 is placed so that the sheets are fed in over it, and is carried by the head 43. The head has a slide block 44 at each end, which is guided by vertical ways 45,46 on the framework. For the purpose of giving the knife and head a rising and falling motion, I

employ any suitable mechanism. The mechanism shown consists of a toggle, cam, lever and connecting rod. The toggle 47 has one arm pivoted at 18 to the framework and the other pivotally connected to the head 43 at 4.9. Two toggles, one at each end of the head 43, may be used if desired, and both may be operated by one cam and lever, or each may haveitsowu operating mechanism. The toggle shown is operated by cam 50 on shaft 51, 1O lever 52, and rod 53 pivoted to lever '52 at 54 and to the toggle at the joint 55 of the latter. The cam 50 is shown as a closed cam, but it may be an open one and the lever 52 be held against it by a spring.

Knife 42 moves between two clamps, shown in Fig. 4. These clamps may be of rubber, or other yielding material or of the form shown wherein two (wooden) bars 56, 57, oneon each side of the knife 42, are mounted in a groove 20 or box 58 in the framework partly open on the upper side. Lips 59, 60 project inwardly from the sidesof this box and each engages a corresponding rabbet on one of the bars 56, 57 when the latter are forced up by springs, as 61, 62. The bars 56, 57are faced with rubber, or felt, or other suitable material. Such facing is shown at 63, 63. Springs 61, 62, may be placed in holes in the bars, which may extend nearly to the bottom of box 58.

The head II moves between guides 33, 3 1, there preferably being a pair of these guides at each end of the head. The guides 33, 3% shown in Fig.1 end at a short distance above the tapes 13, 14, so that the sheets may enter 5 without obstruction. At the other end of the head H, the guides may or may not end in this way. The head I-I may be reciprocated by any suitable means. I have shown cranks and rods 36, pivotally connected to crank pins 37 and to pins 38 on head H in Fig. 1. Or the rods 36 maybe pivotallyconnectedto wrists 39 on gear wheels 40 on shaft 41 as shown in Fig. 2. Shaft 41 is the driving shaft of the machine shown, and may be 5 driven itself by any suitable means.

The means for opening the jaw 23 or grippers 26 will now be described.

A lever 63, pivoted at 61 in the framework, carries a cam 65 at its upper end. The lower 56 end of the lever 63 is alongside of, or is forked and straddles, the rod 53 hereinbefore described in position to be operated by the collars 66, 67 on said rod 53 as the same moves back and forth. Other means for moving 5 lever 63 may beused if desired, but I prefer the means shown. The position of parts shown in Fig. 1 occurs during the descent of the head 11. It will be noticed that cam 65 has just opened jaw 23 or the grippers 26 as the 6 case may be. As head H continues to descend,

the jaws strike the sheet along a central margin thereof, carry it down against and bend it over the knife 12 and clamps 56, 57, as shown by dotted line, the paper being clamped 3; between the clamps and the jaws. The clamps yield to the pressure of the jaws, while the knife remains stationary. The sheet is the said sheets. head, it passes between the two series of severed by the knife and the freshly cut edges thereof are turned upwardly by the downward movement of the clamps and jaws. Rods 68, 69 between which the jaws pass, may be used to support the sheets at this time. While the sheet is being cut as described, roller 70 on lever 52 has reached the operating part 71, of cam 50 and lever 52 begins to operate toggle 47 by pushing it to the right in Fig. 1. This lowers knife 42 until it is below the top surfaces of or is sheathed between clamps 56, 57. Oollar 66 strikes lever 63 and moves the upper end thereof to the left in Fig. 1, whereupon springs 29 move jaw 23 to its normal position, whereby the upturned edges of the (now two) sheets are gripped between jaws 23, and 22. I sometimes use the following devices to keep the sheets having paste thereon clearof the tapes 14: As head moves the knife 42 downward, a pin 72 (on the head or one of its slide blocks) resting in the forked end of lever 73 pivoted at 74- on a shaft or on the frame, moves said lever 73 and raises the other end thereof, bringing the wheels 75 up against and lifting thesheet clear of the tapes. As many of these levers 73 and wheels 75 may be used as desired. As head H rises, the two sheets are drawn inward and upward by the jaws, the bars 76, 77 guiding and directing During the ascent of the guides or guide fingers 78 and 79, and when t it has about reached itsupper position (shown in dotted lines) it engages the upper arms 80,

81 of the shafts 82, 83 carrying these fingers and moves the fingers toward each other. By preference, the fingers on one side (as 78) are opposite the intervals between the fingers of theother side. By this construction, the sheets are frictionally held upafter the arm 27 has struck stationary cam 84! and jaw 23 been opened to release the sheets.

I sometimes apply paste to a central margin as above described. In such cases, when the sheets are lifted by head I'I, their central margins are brought in juxtaposition, with the paste between the sheets. After head H has lifted the sheets as described and as the movable jaw is opened, the folding blade 85 strikes the two sheets along their central margins and pushes the bight between foldding rollers 86, 87, and tapes 88, 89 passing about rollers 86, and 87 respectively. Tapes 88 pass about another roller or set of pulleys 90, and tapes 89 about roller or pulleys 91. These tapes carry the once folded sheetsaway to a suitable folding machine, as will be here inafter described.

Folding blade or creaser 85 may be a vibrating or a rotary or a reciprocating one as shown. Fig. 1 shows blade 85 as carried by a head 92 that movesbetween guides 93, 91. Head 92 is moved at proper times by any suitable means. I show a cam 95 on shaft 51, a lever 96 having roller 97 bearing on cam 95, and held thereagainst by a spring 98.

and at the other to the framework. As

shown, its tension may be adjusted, since they rod 99 is screw-threaded; nuts on each side of lug 100through which the rod passes serve. to adjust the tension of thespringby moving the red. A rod 101, jointed to lever 96 and head 92, completes the means for moving the head. Shaft 51 is driven from shaft 41 by means of suitable gearing, as spurs 40, 102, 103, 104.

Returning now to the sheets after they have been taken by tapes 88, 89, the sheets are delivered by tapes 88 and guide (which is shown double or V shaped for a purpose presently to appear) to the tapes 106 of the folding machine runningabout rollers 107, and guided by rollers 108. Suitable rods 109 keep the sheets from rising from tapes 106, which carry the sheets along over the folding rollers 110, 111. At the proper time, blade 112, vibrating or reciprocating, descends and forces the .bight of the sheets between folding rollers 110, 111; tapes 113 which pass aboutroller and pulleys or roller 1'14 carry the (now twice folded) sheets over folding rollers 115, 116. When the sheets are in proper position over these rollers, blade 117 descends and forces the bight between the rollers. The thrice folded sheet is now dropped into the packer hereinafter described, or otherwise delivered as may be desired.

The devices thus far described cut and fold or paste, cut and fold sheets of six or eight pages.

When cutting and folding asix page sheet on the machine shown, the sheet may extend only to the line 118. If, however, it is desired to have the margin of the two page sheet folded in with central margin of the four'page sheet, the sheet may extend to the point marked 119. This edge of the sheet may be sustained by rod 120, if desired.

If a four page sheet is to be fold,ed, it is run by the tapes 13, 14, orotherwise fed with its central margin over the creaser 121, which may be moved in any suitable way (such movementbeing well known) at the proper time to carry the bight of the sheet between rollers 122, 123. Tapes 124, running about roller 122 and roller 91, and tapes 125 running about roller 123 and roller 107, carry the sheet up to tapes 88 and 106, which carry it into the folding machine just described and is folded thereby.

All the tapes, folding rollers and pulleys arerun by any means ordinarily used for such purposes. The sheets are-fed toward the observer in Fig. 1. a

In the machine shown, the sheets, after being folded by rollers 115, 116, are packed to gether by the mechanism shown. This consists broadly of a receiver, shown as an openended trough, a slidable holder therein and. or pusher having a motion of The packer may be a board or preferably a series of slats, and I prefer to haveanti-friction rolls projecting beyond its working face. The receiver 126 is of trough-like shape, has both ends open, and its bottom is cut away or notched at one end, as

at 127, to allow of thepacker entering for the purposes to be described. The. holder or detent 128 can be slid along in the receiver, being held by friction only. The packer shown consists of slats 129, each slat being secured to two collars, one 130 on cranked shaft 131,.

the other 132 on cranked shaft 133. The collars 130, 132, hold the slats129 at some distance from the centers of shafts 131, 133, where the latter pass through the collars. The effect of this is that theline joining the centers of the circles described bythe ends of the slats does not coincide with the line joining the axes of motion of the cranked shafts, but lies to one side thereof, and in the case shown intersects the same when both are produced. This last is dueto the fact that the arms joining the slats with the shafts 131, 133 are of unequal length. The cranked shafts turn loosely in the collars, but the latterv have no motion endwise of the shafts.

The shafts are jourualed in the frameworkF as shown, and are connected together by theslats 129 and by a link 134 pivotally connected to a crank 135 preferably forming part of the gear 136 on shaft 131, and to crank 137 of, I

shaft 133. The cranks 135 and 137 are preferably at right angles to the cranked parts of these shafts that support collars 130 and 132.

From this itv will be seen that the slats 129 lie in a plane which always remains parallel to itself; thesame is true of each slat; this is.

called a motion of circumduetion in the books, It will be observed that the axes of motion of the shafts 131, 133, which are marked y,z,in Fig. 1, are to one side, while the receiver 126 is on the other side, of the path of the copies as delivered by rolls 115, 116. The trough 126 has curved guides 138 against which the lower ends of the folded'sheets impinge after they are fed downward by therollers 115, 116. The upper ends of the slats 129 come against the sheets at or near the top thereof as they fall, and by the time they impinge on, the guides 138, the slats bear against them from top to bottom. The curve of guides138 is that of the path of the lower edges of the folded copies or auy pointthereimwhich path is the resultant of two forces; one, the force impelling the copies downward,.the other,.the

slats at the same time they are slippingalong the faces thereof and down the guides until. stopped by coming against the bottom of the receiving trough, pushing the holder 128 andany sheets already held in the trough to the I right in Fig. 1.. The slats now move downward away from the sheets. The guides 138 give a rolling contact between the sheets and slats during the placing of the folded copies in the receiver and at the moment of separation, thereby avoiding possible rumpling of j porting the various parts for clearness, but it 1 may be of any ordinary character.

the sheets.

When anti-friction rolls as 139 are used, I prefer to journal them on the rear face of the slats in lugs or risers and to have their peripheries projectbeyond the face of the slats through slots therein.

The position of the slats at the momentof first contact with the folded sheetsis shown in dotted lines 140, and their position at the moment of last contact by dotted lines 141.

I may sometimes use a detent device to hold the tops of the sheets in the receiving trough 126 from falling over toward the slats. I show an arm or lever 142 for this purpose. The end of this arm rests behind the sheets, a stop 1'43 limiting its downward movement.

Arm 142 is carried by pin 144 in the framework at the left of Fig. 2 (but is not shown therein) and arm 145 extends downwardand at one side of the path of thesheets in position to bestruck and moved by pin or stud 146 on meet the cranks that carry theslats 129. This lifts the arm 142 in time for the sheets to be forced to the right (in Fig. 1) whereupon the arm drops in behind them as pin 146 slidesoff arm 145.

The shaft 130 is driven from shaft 41 by suitable means. I show gearsl47,1'48, 149 and 136 for this purpose.

While I have described jaws 22,23 as fixed, or one fixed and the other movable, itis obvious that both maybe movable if desired, and both be moved to open and close in the manner and for the purposes described.

In so far as certain features of my invention are concerned, the packing device may be omitted, and the sheets be folded and delivered in any usual way after being creased by the blade 85. The last named folding apparatus (creaser 85 and co-actin g rollers) may be replaced by other forms of folding apparatus without departing from my invention.

The holder 128 in the trough 126 is not essential, and may be dispensed with.

The fingers 78 and 79 are not essential to the operation of the machine, and may be dispensed with if desired.

In case it is desired to fold sheetsofnarrower pages than that shown, the machine can be readily adjusted for such purposes as fol- 1ows:-The head H lifts the sheets until arm 27 of shaft 25 is operated by cam 84. This cam is part of an adjustable plate, 150, which may be adjusted in any suitable way. It is shown as having two slots 151, 152, through which set screws 153, 154 pass into the framework. By adjusting this plate, the shaft 25 is operated, and thegrippers 26 opened sooner or later so as to bring the central margins opposite the creaser 85.

The sheets cease to until the sheets'are severed. ated differently if desired; thus, it may have rise when the grippers 26 open. In this way,

The tapes, creasers and rollers of thefolding apparatus are run by any suitablemeans commonly used for that purpose.

I have not shown the framework for sup- Knife 42 may have a serrated edge and it may have a vibrating instead of a sliding motion.

Bars 76, 77 may be fixed at one or both ends in the framework, while bar 69 (which is behind lever 63 in Fig. 1) is supported at one end. Bars 76, and 77 may be replaced by rollers, if desired, the two being equivalents for the present purposes.

I do not limit myself to the form of auxiliary mechanism shown and described herein for operating the jaw 23 or gripper 26, since 1 it may be replaced by other forms without departing from my invention.

The knife shown rests with itsedge above the cushions during the descent of the head It may be operits edge flush with or below the top of the cushions aud'be raised as the head approaches it and then be lowered asdescribed.

The movability of the knife 42 is not an essential feature of the present invention; the knife may be fixed and the grippingjaws will still grip the edges of the sheets and bring the two parts along side of each other in the manner described.

Inso far as the packer or pusher is con cerned it is immaterial whether a trough as 126, be used to receive the folded copies or whether they be carried away by delivery belts or otherwise.

The throw of head H may be made adjustable by suitable means to render the machine capable of folding sheets of different dimensions. To do this it is only necessary to lengthen or shorten the arm35, and to shorten or lengthen the rod 36, things within the knowledge of ordinary mechanics.

The cam 84 to open the gripping jaws is not essential since the sheets may be frictionally held with only snlticient force to lift them out and be pulled from between the jaws by the folding devices withoutthe opening of the jaws.

It will be observed that the open jaws on the head H form agroove which is both a cutting and a gripping groove.
