SPECIFICATION forming part of Beissued Letters Patent in 10,300, date, April 3, issa Original No. 186,309, dated January 1; 1877. Application for reissue filed July 7,187.
To all whom it may concern V Be it known that I, LUTHER O. URQWELL, ofBoston, county of Suffolk; and Common:
wealth of Massachusetts, have invented Improvements in Paper-FoldingMatzhines, of
which the following is a specification.
This invention relates to mechanism for fold-,
ing and delivering paper,- and is.especially adapted tofold paper issuing from acylinder or a web-perfecting printing-machine. The paper passing through the printing-machine in a web or continuous-length from a roll, and
being taken by the folding mechanism, is
folded in a direction transverse to its length and cut, and is then folded in an opposite direction, ready for transmission through the mail,-or for other purposes.
' This invention consists in the combination, with a cylinder or carrier and a hinged or pivoted swingingiolding-blade, of astop or deflector to throw outward theedge of such folding-- blade to fold and direct apiece of paper into the bite of a pair of feeding-rollers in the combination, with fold-nipping mechanism and its carrier, of supplementcutters to sever the folded edge of the paper to produce half-sheets, as for supplements; in thecombination, with mechanism adapted to folda sheetin 'a line ".parallel with the axis of the-folding cylinder or carrier, of an adjustable folding-roller-carrying frame whichmay be thrown intoor out of operation when it' is desired to form a sec .ond fold in a once-folded paper; in a hinged or pivoted swinging folding-blade and a feeding device arranged to form a second fold in a sheetof paper; in combination with a guide, a

Fig. 11 is a sectional plan view, showing the devices for operating the movable jaws of theverticalioldingapparatus, and Fig. yr 12 is an-elevation of thesaine. In Figs.1-aud 2 thevertical' folding mechanism is shown as thrown out of conjoint action with the horizontal folding mechanism, whilein Figs. 3 and 4 the vertical folding mechanism is shown as 7 adjusted for co-operation with said horizontal folding mechanism. i
The rotating cylinders or carriers Aland B are mounted upon. shafts 31 4:1, that are supported in bearings provided on a frame, (J, of So any suitable construction adapted to properly sustain the working parts. The shaft 31, in this instance, is the driven shaft, and the cylinders A and B are connected and rotated in, unison by means of toothed wheels aud 40,8 mounted respectively upon their shafts 31 4 15.5 When the folding-machine is to be employed to fold newspapers or other printed sheets'issuing from a printing-machine, the cylinder A is placed at the deliveryendiof the print c log-machine, with its axis parallel with the: I axis of the printing-machine 'cylinders,'and
the-paper'passiug from the printing-machine is led onto said cylinder A and impaled onthe points or holding-pins '6, that project at opposite points from rods 22 through slots in the movable cutting-blades5. There are two oi these blades 5 hung on shafts '20 at opposite points in the cylinder A, their edges being preferably serrated, and each blade acts asoue' 1o member of acutting-mechanism, the other member thereof being a fly',.,7, two of which are pivoted to the cylinder B, so'a's to project coming into position to engage and impale the and thecutting-blade 5, through which they protrdde, are-in the positions they occupy im- .theactionofthe projecting edge of a my; 7,
dire carried in rock-arms 35, hung so as'to vimachine.) .These cams a point of coaction with aprojecting fly, 7, the
'The web of paper, prior to its being severed, is
stretched from nippin g-jaws 51- 53, with which ing-machineflhhsdieingimpaled by one set jcutting blade 5, and thus "divides it, leaving the pins 6. Assuming that the holding-pins 6 shown at the-right-ha nd' side of the cylinder Ai-n Figs. 2 and 3 have just entered the {paper web, the rotation of said cylinder in the direction ot'the arrow will carry the web (which 'in the practical. operation is already impaled der and layit over the fixed supporting-bar 39 fromits peripheral line.- In Figs. 2 and 3 one set of the holding-pins 6 are shown as just paper web (not shown) issuing from the printing-machine. The other set of these pins 6 'mediately after the web of paper is severed.
the cylinder B is provided,betwee u the cylin- .dersA B, over the latter, and back to the printof thepins ti; audit is severed transverselys0 as to detach a shf etfrom its leading end, by
which forces'it past the serrated edge of the the detached end of the web securely held upon and held by the. -holdin'g-pins 6 shown at the left-hand side of the cylinderlonto the cylin- 32, the fixed folding-blade 3 and the slackerbar 33. These slacker-bars 33, of which there are two, are fixed to opposite shafts, 34, that brute onthe rods 36, that fixedly support the folding-blades 3 in the heads of the cylinder A, which shafts 34 are provided with-projectlngends (see Figs. 1 and 5) that rest upon stationary cams 39, (one at each side of the 39 are provided with depressed parts, which allow the slacker-bar'seach to withdraw to its innermost position just as a folding-blade, 3, begins to enter be tween the nipping-jawshl 52.
,In order to fold a sheet or newspaper cen trally, each foldingdylade 3 is placed on the cylin'derA midway'between the two sets of holding-pins 6, which pins enter that portion or t prints sheet constituting its niargim. These holding-pins and folding-blades will be placed at such distances apart upon the cylinder as to hold and fold the paper 'at the desired places. In the present instance the cylinder A carries two sets of holding-pins 6, two movable cutting-blades 5, two supportingbars 32, two folding-blades 3, and two slacker-bars 33, and that the cylinder B carries a fly, 7, at opposite points of its circumference, and-that about equidistant therefrom, and at opposite -points,itis provided with sets of nipping-jaws 51 52. \Vhen, during the rotation of the cylinders A B, a cutting-blade, 5, reaches web of paper will besevered transversely, and the leading emLof-the'web-impaled on the holding-pins 6 will be held thereby and be carried on the surface of the cylinder A toward the lowest point of said cylinder. Dur-' ing this rotation of the cylinders a foldingblade, 3, comesopposite to a pair of open nipping-jaws, 51 52, and presses the paper overlaying it between said jaws, thus doubling or folding the paper transversely, a slacker-bar,
' 33, being simultaneously withdrawn to slacken or give up the necessary quantity of paper to constitute the fold, as in Fig. 4, The mov able nipping-jaw 52 is now closed towardjthe stationary nipping-jaw 51, and said nippingjaws grasp the fold firmly between them. -As these jaws fairly grasp the-said fold a rockarm, 24, fast on one end of the shaft. 20 of the So movable .cntting-blade 5, engages a tappet, 23, Fig; 4, projecting from the side frame, 0, and rocks saideutting blade outward to strip the leadin g end of pins 6. This cutting-blade is then quickly re- '85 stored to its normal position by means of a spring, 21, that is fixed atone end to the rod 22, and bears with its free end under an arm projecting from the shaft 20 of the blade. The
nipping=jaws 51 52 hold the folded portionof o the paper; but the free leading end thereof,
jnstdischarged fromthe holding-pins bythe movement of the cutting-blade, drops upon the, surface of a snpporting-plate,S7, (preferably composed of a sheet or strip of light spring Q metal.) the forward end of which plate guides such free end up to the surface of the cylinder B and away from a sheetholding mechanism, composed in this instance of a curved lip, 27; and a yielding roller, 28. Bgcarry'ing the paper by its fold, mores far enough n the direction of its arrowto bring a cutting-blade, 5, and a fly, 7, together the paper web is again severed, and the nippingjaws 51. 52'then hold a newspaper or sheet :05
both of which are held having two free ends, by the supporting plate 871r'p1ga'inst the s'mooth face-plate 55 of the cylinder B and lapped or laid evenly together.
Each fly 7 as illustrated, is at the ends of arms 42, projectingfrom a shaft, I 43, that is journaled in plates 44, which shaft has-connected with it at one end a spring, 4?, the tendency ofwhich is to'hold the fly against the rear edge of the face-plate 55. The shaft ri 5 43 has attached to it a rock-arm, 63, Figs. 1
and 4,'th"at, asthe cylinder B rotates, strikes a stop, 64, just as the two free ends of the newspaper or sheet, still held by their fold between the nipping-jaws 51 52, are passing berzo tween the fly? and the yielding roller 28 of thesheet-holding mechanism; and when the arm 63 engages the stop 64 thei'fiy-shaft is turned," (the cylinder continuing to move,) and the fly 7 g ential direction, asin Fig. 4, presses the free ends of the sheet down onto the roller 28, or on other folded sheetsor a pile of folded sheets there. As the fly after V. roller- 28, rises and rer 0 previously deposited having depressed th. leases the free'ends f the sheet, the said ends] are pressed upward by the roller 28 and caught and held betweenits surface-and thatef the. lip 27, saidroller 28' being hung in arms 60 6 1,
the paper off from the holding; J 1
When the cylinder m3 a plate-carrier 1 1 o thrown out away from the cylinderinwa tanr25 p on the end of its shaft 53, meets a stationary pivoted on a shaft, 62, which is seated upon a I full sheets into half-sheets there is arranged,
spring, 163, that is fast to it and bears upon the bed-plate of the frame 0. This holding mechanism thus operates to hold each sheet and arrest its onward movement, said sheet being released in proper time from the hold of the nipping-jaws51 At the opposite end of the fly-shat't 43 from that shown i.n Fig. lit is provided with a rock arm, 45, Figsi2 and 4, that, as the fly rises from the roller 28 and leaves the sheet, en-
gages a fixed cam,-46, and permits its axis to turn gradually under the action of its spring 43, and thus carry the fly into its normal position of resting upon the rear end of the faceplate 55, when it is again ready to act as a member of the cutting mechanism.
The operation of the mechanisms as thus far described will deposit sheets once folded in a pile, and their folded edges will be parallel or uniform, orsubstantially so, whereby they may be carried away in a pile, ready for rapid handfolding.
The sheet-nipping mechanism is composed ofa stationary jaw, 51, extending across the cylinder B, and ot a movable jaw, 52, carried at the ends of arms 18, projecting from a shaft,
53, and preferably faced with india-rubber or leather. Each movablejaw52 is moved awayfrom its companion-the stationary jaw 51- by means of a spiral spring, 54, coiled about and fastened at one end to the shaft 53, its other end being secured to an arm, 38, projecting from the rear of the face-plate 55. (See Figs. 2 and 5.) Thesejawsarethus normally held open, or in position to receive'a foldingblade between them. At the proper time for a nipping-jaw, 52, to close onto and grasp the fold of the paper presented by the foldingblade 3 a' rock-arm, 56, Figs. 1, 5, and 6, fast cam, 57, and is thereby rocked forward, so as to carry the jaw 52 toward the jaw 51','and thus grasp the fold of'the paper between them as the folding-blade 3 is withdrawn there from, Fig. 4. This rock-arm 56 bears upon the cam 57 as long as it is necessary toh'old the folded paper, and when the same is to be released the rock-arm passes off from the cam and permits the spring 54 to vibrate the movable jaw 52, and thus open said jaws.
This cam 57 is composed of two plates-an.
auxiliary movable plate, 1-, placed alongside its main fixed plate 0. The auxiliary plate 1 has a curved slot, through which passes the set-screw 26, that is tapped into the main plate 0 to hold the same stationary. The auxiliary plate 1 may be moved on the'shaft 41, and be fixedly adjusted by the screw 26 to increase the bearing-surface of said cam 57, and thus extend the time during which a rock-arm shall bear upon it to hold the jaws 51 52 in their closed position,
In case half-sheets or'su'pplements are to be delivereihitfis only necessary to set up the types to print half-sheets, and then cut and fold as has been described; but to divide the able nipping-jaw 52, is attached to the nipping,
cutting mechanism, a movable cam-segment,
37, is provided, This cam-segment is arranged,
to move laterally to and from the side frame, being properly guided by pins 115115, that slidejn the frame, and are properly moved by a driving-screw,'106, that is tapped through the cam-segment, and caused to turn without moving longitudinally by means of a holdingplate thatbears upon a shoulder of said screw. This cam-segment is shown in Fig.5 in its rearward position, where the arm 56 clears it, but may be moved inwardly into operative position, or so as to intercept the rock-arm 56 and force this'arm to pass over it, so as to increase its rocking movement, which greater movement of the rock-arm causes the shaft 53 to continue to move after the jaw 52 has'inet thejaw 51, and to carry with it the blade 16,
which is thus forced through the projecting folded edge of the paper nipped and held by thejaws 51 51-3, whereby the folded sheet is divided into two unfolded half-sheets,-which remain within the grasp of thejaws. The blade 16, in the structure shown in Fig. 6, is caused to make a shear out by means of an endwise movement given to it by inclined slots in the inner face of the outer plate of thejaw 52, into which the ends of the arms 98 protrude, said arms being loosely enough attached-to the shaft '53 to admit of slight movement.-
A modified form of supplement -cutter is shown at the upper portion of the cylinder B in'Fig. 2, and in detail in Fig. 7, where, in-' stead of using the jaw 51 as the cutting-edge, there is connected with said jaw a. spring cotting-blade, 108, wliich, being fixed at one end only, and extending diagonally across the edge of the cuttingblade 16, and being a spring-blade,prodnces a shearing cut when the blade 16 is. forced past it. The arms 56 are gslotted 114 to p'assthe endof the screw 106,1

This frame carries jonrnaled in 'its arms 2 -68 69 s an of horizontal folding-rollers, 6565,

This rotating folding-blade D is donblethat is, it is composed of a shaft, 3, armed with 'two folding-blades, 94, projecting .in opposite directions, whichblades are alternately'bron ght into position; v The shaft .9 of this rotating',folding blade,is supported "in I proper bearings, and provided with opposite rockrarms, 95, ada'pted' to be 'en gaged by tapp'et of a toothed wheel,93, that is fast on thelower "end of the shaft 80 of the vertical cylinder or carrier I.-
Holding-pins rections-nearthe lower end of the shaft, rest the rotating folding-blade D to its normal position after-each operation of it, thus completing its semi-revolution, the weight of the shaft 8 and the folding-blade being sufiicient tocause the holding-pins 96 to ride'down the inclined 'faces of the crown-cam 9?. The shaft 80 of the vertical folding-cylinder I has at its bottom end a bevel-gear wheel, 81, that is engaged by the bevel-wheel 82onthe shaft 83. This vertical folding-cylinder I is provided ping-jaws 17, that are held open by springs 1'9, and with hinged or pivoted tblding-blades- J5, that are held closed by springs 14',and pro-- vided witli'rock-ai'm's i, in like manner as are by the cylinder B, a stop or deflector, 9,be ing engaged bysnch rock-arm s, so as to throw'the said hinged or pivotedfolding-hlade 15 outward between folding-rollers 58 .59, mounted vertically in. stationar, bearings, whereby a once-cross-folded sheet.

When this foldingblade reaches the position shown in Fig. 9 it will leave said jaws, (the jaw 17 grasping the fold of the sheet,) whereupon its holding-pins 96, which in this movement-of the folding-blade have ridden up the inclines on one side of the crown-cam 97 and passed its highest points,
will, under the weight of the blade and its shaft, descend the opposite inclines of said crown-cam until they rest in the lowest (lepressions of said cam, thus completing a semirotation of said foldingblade and causing it to stand in the position shown in Figs. 2, 4, and 8, where it clears the path way of the sheet,
descending into the vertical guide until it is again rotated by the repetition of its folding operation. As the thrice-folded sheet is carried onward by the rotation of the vertical folding-cylinder it is drawn past vertically-arranged folding-rollers 58 59, which are revolved in unison by gear-wheels 91 92, that engage with the toothed wheel 93. Vhen the head of this sheet has passed a proper distance beyond the folding-rollers 58 59 the rock-arm i of-a vibrating folding-blade, 15, will engage the stop or deflector 9, and thus turn said blade outward to force the sheetnpon a fourth fold ing-line into the nip of the rollers 58 59, the rock arin 89 passing off from the cam 90 at the proper instant to allow the spring-seated movablenipping-jaw 17 to open and release the sheet. The springs 14 restore the foldingblades 15 to their normal positions against the rear ends of the jaws 17 after said blades pass out from between the rollers 5859. The sheet then passes through the rollers 58 69 and issues therefrom folded four times. In this instance such folded sheets are rapidly fed alternately into angularly-arranged packing-boxes 100, of proper dimensions to receive thcin.'. These packing 1 boxes are provided with packing arms 25, that are vibrated by a rocking shaft, 103, at the.lower end of which is a crank, 104, connected by a. link, 110, with an eccentric strap, 111, embracing an eccentric, 105, on the shaft 80 of the vertical cylinder. The folded sheets emerge from the folding-rollers 58 59 alternately on opposite sides of the vibrating packer 25, and are by its movements carried before it into one or the other of the packingboxes 100, being forced against movablepack-. ing-heads, as 101, that gradually'slide rearw'ard as the sheets accumulate. As each sheet is moved by this packer 25 into a box, 100, a stud, 12, projecting from its bottom member, 25, strikes the face of an inclined cam, 13, extending upward from a rock-arm, 113, fast to the lower end of a shaft, 102,1:0 which springflngers 11, having right-angled ends, are hung,
andmoves the arm 113, thus swinging said fingers outward, so as not toobstruct the passageway for the sheet being'delivered. As thm'vi brating packer retreats itsstnd 12 passes be: hindth'e cam 13of the spring-fingers,which then move forward and prevent the sheets mm crowding backward. Anointing mechanism:
the number of sheets delivered folded.
It will be seen by those conversant with mechanism that the mechanical details for operating the parts actively engaged to fold the paper anddeliver it, as described, can'be ya'ried without'departing from this invention,
as equivalently operating, connecting, and driving mechanisms. may be'employed.
The principal element-of the supplement- Lcutter is a. blade carried by a sheet nipping being connected with the shaft, so that the latter, with the blade, can move farther than the jaw. This feature of my'invention-could becarried-out by many difl'erent connecting and operating devices otherthan those shown,
which would bemere equivalents. So I do .not
limit'this feature of my'invention to the mech- 'anism shown.. The supplement-cutter might be placed in connection with the stationary jaw, and have mechanism arranged to operate it after the jaws have met and grasped the paper. Each fly? carried by the rotating cyl 'inder B may be thrown out and into co-operation with the roller 28 by other devices than those shown and described. The part 27 of the sheet-holding mechanism might be hinged and arranged to be moved backward as the. flyfi' presses the sheet downward, and then come forward over the ends of the sheet, like a hook, as the fly moves away. A spring bar or rod might take the place of the supportingplate 87. ,Although a fly operating to seize the rear ends of the sheets and aid inarrest ing them is described herein,'mechanismhaving such a mode of operation is not broadly claimed herein. v
