SPECIFICATION formingpart of Letters Patent, N o.658,919, dated October 2, 1900.

I Application filed September 19, 1899. Serial No. 731,629. i110 model.)

To all whm'n it may concern.-

Be it known thatI, MATTHIASKOCH, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Machines for Folding or Plaiting Paper; and I do hereby declare that the following is a in H, clear, and exact description of the same.

My invention relates particularly to machines for plaiting paper for carpet-lining, although it may be applied to advantage wherever paper or other easily-manipulated sheet material is to be folded or plaited.

The object of my invention is to provide a machine that will do a greater variety of work than machines heretofore used for this class of work, one that will have fewer parts, and

to turn out a better class of work than has been possible heretofore.

The invention may be said briefly to consist in mountinga pair of reciprocating blades to reciprocate in diagonallyintersecting planes, each of which intersects in turn a horizontal plane extending between a pair of feed-rollers, upon each one of which one of. said blades yieldingly impinges. A series of carrier-rolls equal in number to the thicknesses or layers it may be required that the finished lining consist of are mounted at the rear of the machine, each roll carrying a length of paper. A conveyer extends from these feed-rollers to an inclined table hinged at its rear end to the frame of the machine and resting at its forward end upon the receiver-roll, which receives and windsupon itself the folded paper. A roller extends transversely of the conveyer in a position to bear upon the folded paper as it is beingconveyed, and a series of strips having one-side coated with adhesive substance is fed between said roller and the work, with its adhesive side in contact with the latter. I also provide a measuring device for measuring the work as it passes through the machine. This measuring device consists of a measured and marked strip which passes from acarrier-roll to and beneath the last-mentioned roll and around the receiver-roll to a take-up roll.

Other novel features of construction are embodied in my invention; but for full coinprehension thereof and of the foregoing ret= erence must be had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts,

and wherein- Figure 1 is a left-hand side elevation of my Fig. 7, a detail plan view of one roll for carrying the paper to be plaited',.and Figs. Sand 59 are detail views of the receiver-roll. consequently be less complicated, and be able 5 The frame of my machine has at each side thereof a laterally-projecting wing-piece constituting tables I; and c, and the bolts that secure the tables in place extend through the tively. The trunnions of the upper and'lower feed-rolls h and 't', respectively, rest in the U-bearings f, and the outer ,or compressor bearing g.

rollsj and k of the conveyer-rest in the U- The upper feed-roll h is caused to bear yieldingly upon the workpassing between it and the lower roll by a helical spring l, while the upper com pres'sor-roll j is caused 1 to bear with uniform but adjustable pressure l upon the work by a set-screw m. A pair of small rolls e are mounted in the bearingplates in close proximity to the feed-rolls, and

a series of separate loops of wire n, independand the compressor-rollsjandit.

ent of one another, take over saidsmall rolls The upper lengths of the loops which take over the roll It and its corresponding small roll pass through perforationsin and run along a table '0, extending fromthe roll is to the feed-roll 'L, as shown particularly in Fig. 2. The bearing-plates have horizontal extensions, and the portion of said plates in rear of the feed-rolls h and t' are horizontal, and each has-a pair of horizontal bars 10, supported thereon a sufficient distance above the bearing platesand one another to provide horizontal guideways q and 1', respectively, for the cylindrical ca rrier-bars s and t of the upper and lower plaiting-knives .s and t, respectively. These planing-knives are each made up of a number of sections it, connected together at their forward ends by a cross-bar v and at their ends to their carrier-bars, and they are of sufficient length to project when in their foremost position to within a short distance of the vertical plane of the axes of the feed-rolls.

In order to form'a boX-plait, the plaitingknives m ust alternately come into sufficientlytight contact with the paper from which the lining is being formed to move said paper forward with them, the paper forward of the knives meanwhile being held by the feed-rolls against movement, and then each knife must move back out of the path of the other knife. The upper knife is caused to perform its function by means of a bell-crank lever 20, formed in one with a sleeve 00, secured bya set-screw rigidly upon the right-hand end, looking from the front of the carrier-rod .9. One arm of this bell-crank lever has a link 150, rigidly and adjustably connected at one end thereto by a bolt 2, while the other end thereof is yieldingly connected by a retractile helical spring 3 to a stationary part of the frame. A shaft 4 extends transversely from side to side of the machine and bears in the bearingplate 01. A large gear-wheel 5 is mounted rigidly upon the end of said shaft adjacent to and overlapping the lower arm of said bellcrank lever 10, which is tripped upon by an inwardly-projecting pin 6, carried on the inside face of said gear 5, near the periphery thereof, thereby causing the knife 8 to impinge upon the paper therebetween and the lower feed-roll.

In order to reciprocate the upper knife to and from the lower roll, an eccentric 7 is mounted rigidly upon the shaft 4 between the bearing-plates, and the collar of this eccentric is connected by a link 8, Fig. 4, to the lower end of a lever 9, mounted rigidly upon a shaft 10, which is in turn mounted at its ends in thes'aid bearing-plates, while a pair of singlearm levers 151 are also rigidly mounted upon said shaft 10, one near each end thereof, and

the upper ends of these levers are pivotally connected by links 12 to the carrier-bar s of the upper knife. It is obvious that the rotation of the shaft 4 will oscillate the lever 9 and through said lever rock the shaft 10, I which will in turn oscillate the levers 151 and through the link 12 reciprocate the upper knife 3.

The lower knife hasa reciprocal movement toward and from the feed-rolls, imparted thereto by the rotating shaft 4 through a gear 13, mounted rigidly upon said shaft and intermeshing with a gear 14, mounted rigidly upon one end of a stub-shaft 15, supported in a pillow-block 16, secured upon the top of the base. A crank 17 is mounted upon the other end of said stub-shaft and is connected by a link 18 to the lower end of a lever 19, mounted rigidly upon a shaft 20, rotatably supported in socket-bearings formed in the inside faces of said bearing-plates d. A single-arm lever 21 is also mounted at one end rigidly upon the shaft 20, and the upper end of this lever 21 and the upper end of the lever 19 are each connected by a short link 22 to the carrier-bar f of the lower knife 15. This lower knife is caused to impinge upon the paper between it and the upper feed-roll (alternately with the impingement of the knife .9 upon the lower feed-roll) by a cam 23, mounted upon the shaft 4 outside of the bearing-plate d and near the left-hand end thereof, looking from the front of the machine. This cam acts upon a block 24, formed in one with an arm 25, fulcrumed to the bearingplate, and causes it to at times assume a posit-ion to act as a cam to impart the required upward oscillatory movement to the knife through an antifriction-roller 26, mounted upon a stub-spindle 27, adjustably secured to the slotted outer end of an arm 28, through which slot the screw-threaded diminished inner end of said spindle takes and receives a nut 29 thereon. This arm 28 has its inner end increased in width, as at 30, to take over the end of the bar If, to which it is adjustably secured by a pair of set-screws 31, the latter adjustment being required to take up the wear between the cam 23 and block 24 and block 24 and the antifriction-roller 26, while the adjustment of the roller longitudinally of its carrying-arm 25 is to regulate the extent of movement of knife t in its upward swing upon the upper feed-roll, the extent of movement being of course increased or diminished according as the roller is adjusted toward or from the bar If.

I prefer to make the carpet-lining, as heretofore, from three independent sheets or lengths of paper, because in that way it is easier manipulated than when made from a single length of heavy-say three-plypaper, although, if desired, single or two or more lengths can be manipulated. In order to use three lengths, I mount three carrier- rolls 33, 34, and 35, respectively, in bearings upon a rearwardly-extending frame 36, bolted to the under side of the tables I) and c. The lengths of paper are taken from the carrier-rolls under a guiding-bar 37 and carried over a rod 38 (which keeps it from sagging) between the plaiting-knives to the feed-rolls.

To coat one side of several strips of paper with adhesive substance-paste, for instanceand attach said strips to the plaited paper to bind together and prevent the plaits spreading, I mount, preferably, four carrierrolls 54, each carrying a rolled length of paper in a strip upon a frame 56, secured rigidly to the front of the machine. These paper strips are taken from their carrier-rolls over a bar 57, mounted rigidly in a frame 58, bolted to the main frame of the machine, as at 59. This frame 58 has a diagonally upwardly projecting portion 6], in which are ICC supported a pair of rolls 62' for feeding the strips 55, these rolls being carried in bear ing-blocks 63, taking into the parallel sides of said frames, and the upper roll being caused to bear yieldingly upon said lower roll by means of an expansible coiled spring 64, bearing between each of the bearing-blocks 63 of said upper roll, and a cap 65., extending across the open upper end of each of said parallel sides. Ashaft 66, having four rollers 67 rigidly mounted thereon, bears in said frame 58, with the rollers 67 dipping into an adhesive compound, such as paste, carried in a dish 68. The strips are taken over these pasting-rollers, they may be termed, to and beneath a pressure-roller 69, resting in slots 70in the main frame of the machine, between the upper and lower lengths of the upper wire loops 'n of the conveyer, at which point said strips become attached to the plaited paper and travel along therewith through the compressor-rolls j and 10; An inclined table 72 is pivotally connected at its rear end on a line with the horizontal table of the conveyer and rests at its forward end upon a receiver-roller 73, mounted in the upwardly-turned forward ends of a pair of diagonal arms 74, bolted at their rear ends to the tops of the tables I) and c. This roller, which is of peculiar construction, as will be presently set forth, has a pulley 75 mounted rigidly upon one end thereof, as shown, and this pulley is operatively connected by a crossed belt 76 to a pulley 77, mounted rigidly upon the corresponding end of the shaft 4, while this latter shaft is driven by a main driving-shaft 78, bearing in a pillow-block 79, bolted to the table I), and having mounted thereon loose and tight pulleys 80 and 81 and a gear 82, intermeshing with the gear 5, mounted upon the adjacent end of the shaft 4. A liy-wheel 84 is mounted upon the end of said shaft 78 to cause the machine to, run evenly. The receiver-roller 73, above mentioned, is of wood, having an axial groove 85 and a pair of ferrules 86 and 87 on its ends, 86 having a socket 88in line with the groove 85, and 87 being tapped to receive a set-screw 89 for securing a small clamping-plate 90 over the adjacent end of the groove 85. The end of the completed lining is secured to this roll by a length of stiff Wire 91, which is inserted at one end in the socket 88 and stretched over the end of the lining and pressed into the groove 85, thus firmly fixing said end of the lining in said groove, where it is held against displacement by the clamping-plate 90. When the desired quantity of carpetlining-say fifty yardshas been completed and rolled upon the roller, the belt 76 is removed from the pulley 75, the roller lifted from its bearings, the screw 89, and with it the clampingplate 90, loosened, the wire withdrawn from the roller, and the roller from the rolled lining.

The tension of the belt 76 is regulated by means of a tension-sheave 120, carried by an arm 155, fulcrumed upon a stationary trunnion 122, upon which a ratchet-wheel 156 is rigidly mounted, the arm 155 carrying a spring-pawl to engage the ratchet-wheel and retain the arm and through it the tensionsheave in any position to which it may be moved.

The carrier-rolls at the rear of the machine are also of peculiarconstruction and provided with a pair of axially-bored conical bushings 92,which are forced into the ends of the axial opening of each rolled length of paper from which the lining is to be made. A rod 93 takes through these bushings, and the bushings are secured against displacement from the rolled paper by set-screws 94, taking through said bushings and bearing upon the rod 93, while the rod rests in the bearings, wherein it is held against longitudinal movement by a collar 95 at one end and a tensionwheel 96 at the other. This tension-wheel is in the form of a sheave, over which takes a cord 97, secured at one end to the floor of the building and weighted at its other end, as at 98.

The feeding of the paper is eifected, after it has been plaited, by means of an oval cam 100, eccentrically mounted upon the shaft 4 outside of a bearing-bracket 101, (in which it bears,) secured upon the table 0. This oval cam acts upon an antifriction-roller 153, mounted in the end of lever 102, fulcrumed upon a short shaft 103, mounted in a hearing 104, secured upon said table 0, this lever being, through its antifriction roller, kept yieldingly in contact with the cam 100 by a retractile coiled spring 105, connected at one end thereto and at its other end to an arm 154, bolted to the top of the table 0. A spring-pawl 106 is carried by this lever 102 in a position to engage and intermittently rotate a ratehet-wheel 107, mounted rigidly upon said stub-shaft 103, upon which is also mounted agear 108 and an oscillatory bracket, the gear being rigidly mounted, while the bracket is loose. This bracket is oscillatory only for purpose of adjustment and is in the form of a slotted quadrant 109, having a downwardly-projecting longitudinally-slotted arm 110. The bearing 104 is formed with an arm 111, transversely slotted to carry a bolt 112, which projects through the slot in the quadrant and has a tightening-nut 113 thereon, while a bolt 114 takes through the slot in arm and has a set-nut115 thereon and carries a gear-wheel 116, which intermeshes with the gear 108. The gear-wheel 116 in turn intermeshes with the lowerone of a pair of gear-wheels 117, mounted upon the main feed-rolls, the upper feed-roll having a gear 118 mounted atone end thereof outside of its gearl17, while intermediate the gears 118 and 117 a pulley 119 is mounted upon the upper roll and is connected by a belt 120 to a sheave mounted rigidly upon the upper conveyer. A gear-wheel 121 is mounted at the opposite side of the machine to that at whichsaid gears 117 and 118 are located upon the end of the shaft of the pasting-rollers and intermeshes with a gear-wheel 122, mounted rigidly upon the lower of the strip feed-rolls, on the opposite ends whereof a pair of intermeshing gear-wheels 123 are mounted.

The gear 118 fortransmitting rotary power from the feed-roll-operating gears to the rolls for feeding the adhesive strips is of greater diameter than the gear for operating the feedrolls in order to cause the main feed-rolls to travel at a less speed than the strip-feed rolls, and thereby cause the strip-feed rolls to feed a greater length of the binding-strip than that of the plaited paper fed by the main feedrolls. This has the effect of imparting a springy nature to the completed lining, while the oval cam is mounted eccentrically-that is to say, nearer one end thereof than the other,to cause the work to be fed a greater distance after the lower knife has acted than after the upper knife has acted. This is necessary for the reason that after the lower knife has acted the work must be fed a distance equal to one complete plait and the space between said plait and that next following, while after the upper knife acts the work must only be fed a distance equal to one complete plait.

In order to determine the output of the machine, I mount a rolled length of measured tape 125 upon a roller, mounted in turn in the end of a bracket-arm 126, secured to the frame 58, this tape being drawn from its roll by the rolls 63 for feeding the paper strips and is taken at one side of the pasting-rollers 67, over the edge of the dish (38, beneath roller 69,0ver receiving-roller 73,and beneath a guiding-roller 127 to a winding-rollerl28, mounted upon a shaft 129, which also has a sheave 130 mounted thereon and operatively connected bya belt 131 to a sheave 132, mounted upon the adjacent end of stub-shaft- 103.

The operation of my improved machine is, briefly, as follows: The ends of the lengths of paper from which the lining is to be made are first inserted between the feed-rolls, and the machine then is brought into motion by shipping the driving-belt from the loose to the tight pulley. Ihave found that the knives will not slip if each acts upon the paper at an angle greater than forty-five degrees relatively to the paper upon the roll. During a complete cycle of operation one of the knives say the upper-moves forward to within a short distance of the work and is then lowe-red into contact with the paper, causing it to bear upon the said roll and the knife by friction to grip the paper, the knife continuing in its forward movementpushing the paper forward and causing the portion between the knife and the feed-rolls to fold. The pin 6 upon the gear-wheel 5 having passed the lower arm of the bell-crank lever to, the spring 3 causes the knife to move out of the path of the lower knife. The work is then fed during the dead-centering of the eccentric 7 and crank 17 with their links, the upper knife having reached and simultaneously the lower commences to perform the functions just described with relation to the upper knife, except that the lower knife is caused to first push the paperalongthe surface of the upper feed-roll, and the pressure of the lower knife upon the upper feed-roll is caused by the antifriction-roller 26 of arm 28 running along the upper cam-face of the arm 25 and block 24:, and the pressure is relieved from the lower knife, and the latteris moved out of the path of the upper knife by the cam releasing the saidintermediate parts and allowing the knife to drop by gravitation.

In order to produce a springy carpet-lining, I cause the feed mechanism of the bindingstrips to feed a greater length than that of the complete lining fed from the plaitingknives by the main feed-rolls, as before mentioned. My reason for doing this is because the main feed-rolls must compress the plaits to feed them, and if alength of binding-strip were fed equal to the length of completed compressed lining said lining would be too fiat to have a springy nature. Feeding a greater length of binding-strip in proportion connects the plaits together after they have opened out to a certain extent, thus im parting a springy nature to the completed lining.

I have found that by constructing and operating a machine according to the foregoing the plaits will be made more uniform and that their uniformity will be retained, while by consulting the measuring-strips the length of the completed lining can at any time be ascertained at a glance.

An important feature of this invention is that by removing either of the knives a single plait can be formed, and by adjusting the feed plaits of any desired length can be formed.
