drawn against the roll by a light coiled spring ll holding the strip against the cir- 'r lilli i'l'iintlkll surface of the roll of paper. From the roll 5 the band of paper is passed h- We. feed rollers 12 and 13 which are re- ;ly mounted below it. One of these 1"4 l2 in stationary bearings and is d by a chain or band 14 from a shaft 5: x driven by suitable means from the f: nuztion shaft 16 of the machine. 'T h arings of the other roller 13 are free to more tmrard the drive roller 12 against which it is pressed by light springs 17.

From the feed rollers the paper passes downward between, the cutting kni-es 18 and 19 and arross a fence plate 25, the depth of whuh plate below the plane of the knife substa n1 iailv corresponds to the Width of the paper. The imiwable knife blade 19 is ag -rm toward the other to effect the cut by a quick movement cam 20 on the shaft 15, {em- Fig 2) acting through the intervention of a lrrer 21 pirotally mounted at 22. This movement is made against the resistance of 0 spring 33 which returns the knife. Betw en the feed rollers and the knife blade the paper passes between oppositely concaved guards which provide accommodation for the mnlinumlsl) fed paper Whilethe knife is elating "l he ieiaie plate 325 has a slightly tapered right angled fold 26 bent in it across its llliilliilgl'ill, into which the cut square of paper 5* is pressed by a blade 27 to impose ih first fold. as indicated by m and shown in Fig. 1'. This first fold blade is secured, as shown in lfigs. 2 and 4, to a base member whi h is slidable in guides 29. The blade is proforma] into the fold 26 of the fence by a. quirk action cam 30 on the shaft 16 acting: through the intervention of'a lever til pivoted at 32 and connected to the slidable base nienil er SBQL and withdrawn from the fold by 'a spring 3-1. wilhdrawal of the blade require tq-fbe quicklyperformed, that the blade maybe 01111 of the way of the nextsquare of papegl-ao it is delivered from the feed rollers. 5

The blade 36 by wh ch the quarter fold a, as illustrated in Fig. 8 is imposed is eudwise, projected into the slot 35, is earrierl length-- wise of that slot to the location 37, and is endwise uithdrawn at that place by the following means: Each hlatle fi l is seenred on a stud 3P5 projeeting from the: center of a square (lie lJlUCk 35), the square sides of which are respectively"parallel and at right angles to the leading edge of the blade se cured to it and has a square neck ill the faces of which are disposed diagonally to the square of the die. The hlade is secured. on the stud by a nut and is retained with its leading edge parallel to one side of the die by a steady pin--ll lilting a eonesponih ing aperture in the blade. A series ol these (lies With their blades 36 attached, are mounted in a rectangular slideway l2 whieh is horizontally disposed parallel to the plane of the slot 35. The corners of this slid ivray are square 50 that the dies may travel along its sides and ends and maintain the leading edges of the blades always parallel. The dies are moved along the slideua by an endless chain 4; taking around eorner sheaves ll rotatably mounted in the supporting frame beneath the slideway. ()ne of these sheaves 44 is a sprmket wheel and mounted on a shaft 46 which is; driven by bevel gears 47 from a shaft IS driven by a rhain or hand 49 from the lirsl motion shalt ll? of the machine.

Each die 39 with its blade tlll is moved along the reetang'ula r slidrwav hv a member 50, see, Figs. 12 and lil. whirh is wrured to a link of the chain and is bent around the outer edge of the slidewa v to rnggnjie the after rorner of the square nerl; ll) of the die For convenience ol' ronsiruelion this lllt'illlrl' fill ma be made in two pier-es. as show n.

At this phn-e an angular noteh I of .ipproxinniteiv thirty degrees is remored from the rover plate and base plate of the slot 35. the axis ol the angle forming a forty-live degree angle with the line 01 travel, or with the end ol' the slot.

Pivotally mounted at 3-; and El below the plane of the slot 35 triangular blades 55 and 513 are mounted to move across the triangular noteh ST in planes that are parallel lo that of $3 The pivot pins fill and ."il of these lilades have short levers ST and h seenred on then] and the ends of these levers are connected by rods 59 to the ends of levers no mounted on pirot pins til. the other ends of whieh levers are aeted upon in parallel planes by quirk nmveinenl rains l3! seeured on the first motion shall ll. By this merlp auisn: the triangular blades are. one a little in adrunre of the olheix moved aeross the notch JJT below the plane of the slot J55.

ln alineinent with the axis of the angular nolrh 3T a ineniher I35 is mounted in a slidewa on to move axially into and out of the triangular notrh I37, and in the outer end of the slidahle member (if) a presser plate 67 is hing d at 65, the free'end of whi h presser plate is shaped to eontorni to the triangular n l h ll. The slidahle member 433 is projerled into and withdrawn from the noteh ll? h v a lever Tl pivoted at 1'2 and eonneeted by a York or slotted end to a pin T3 in the front end of the slidahle inendler (35. This h-ver 71 has a small roller on a pin T hwhirh roller proiwls into the fare groove of a rain r51! seenred on a shalt T l whieh is driven by a lloolts joint T5 from a shaft T whieh again is driven at the required rate of speed In a rhain TT from the first motion shaft lfl. "l'he g -roove ol the ram llll has a eourentrie portion that will allord the press-er plate 37 a period oi rest, while it is within the notr'h HT and the triangular blades 55 and 56 are l ohlin the opposite l'ol'liel's ol' the ([Hzll'tll' l'oldeil serviellr over it.

The hinged presser plate 37 has an adiuslahl'e r-ipring'Tl'w' whieh tends to hold it in the plane of its movement, and it is lifted against the resislanee of this spring to the angular position, as shown in Fig. 5 by a roll r on the end of a short lever T pivoted at h to the slidahhmember 671, the lower end of whim-h lever projects downward so that at the outward limit of the movement of the slillable member it engages a corner of the frame of the ma hine, as shown in full lines in Fig, 5, to lift the presser plate. The pivot is so arranged in relation to th contact of the roller on the lever on tluunderside of the presser plate that the plankis stably supported until the lever is forcibly thrown down by the lower end oi the le er engaging a PI'UJQCtiOH 81 at the inner limit of the presscr plutes movement. When the quarter folded serviette has reached the lo cation of the notch 31 and the blade 3" which folded and carried it there is withdrawn, the resser )late 67, angled upwnnl, as shown by the full lines, is projected into the notch 37 the lower end of the lever 7! engages the projection 81 and is thrown down, and the presser plate drops under the action of its spring 78 and its own weight 'onto the quarter folded serviette and presses it below the lever of the triangular blades and 56 folding the corners upward, as shown by the arrows in Fig. 9. 'lhese blades .55 and 56 are then moved across the notch 37 and fold the corner pieces over the cen tral portion, as in Fig. 10. The presser plate is then withdrawn and the operation of folding is completed.

Just below the level of the plane of more ment of the triangular blades and 5t; :1 light spring 83 projects outward lmyond each side of the notch 37 below which springs the preer plate (37 presses the Folded ser iette so that they are prevented from rising to interfere with the succeeding serviettes. The folded shviettes are pressed by the succeeding ones into a chute 82 which islcu'rved upward to deliver them where they may be bound in bundles for packing.

Although specifically described as impos ing the folds illustrated in Figs. 7, 8, 9 and 10 the mechanism may be arranged to told them differently if so required. Thus the first fold, instead of being parallel to the sides of'the squareof paper, may be dingo nal therewith and the second fold at right on les to the first.

,do not desire to confined to the exact nsti'uction of the machine or of the mecha- 'nisrn 'for operating the several folding;

blades, or other moving parts, but claim ad y flmreans described for imposing the required folds one paper serviette.
