1'0 all whom it may concern:

Be it known that I, ALBERT DAY, a subject of the King of Great Britain and Ireland, residing at2l Hartley avenue, Leeds, in the county of York, England, have invented new and useful Improvements in or Relating to Machinery for Forming or Making Paper Bags, of which the following is aspecification.

This invention has reference to improvements in the machines described in the specification of Letters Patent of the United States granted to Charles Herbert Day and Albert Day on the twenty-ninth day of March 1904, No. 755754, for forming or making what are known as open bags. In the said specification means are described and shown for forming the bag from a roll of paper, and arranging the longitudinal edges of the'paper, out of which the bag is formed, to be folded over eachother at or about the center of the upper surface of the intermittently rotating former.

The objects of the present invention are to provide means for first, feeding one or more sheets of paper,which may, or may not, have been previously passed throu 'h a printing prcss,separately to the folding box or mold and iormer; second, arranging for the longitudinal fold of th bag be on one of the upperedges of the for .;1';' third, apparatus for holding the sheets of paper in position during the end creasing and folding operations; and fourth, supplyin the gum or paste or other adhesive materia to the end and other folds of the bag for re-' taining them in position. I attain these objects by mechanism illustrated in the accompanying drawings in which Figure 1. is' an end elevation of a rectangular. bag showing its end folds.

Like arts in all the views are marked with similar otters of reference.

The folds made in the bag by the machine described in the aforesaid specification are formed withan end chiefl in the'sha e of a rectangle, as shown at Fig. 1,--suc used for acketing dry soap,-in which the upper an lower projecting

portions

1, 2, of the bag are folded and pressed against the end of the former, then the two side pieces '3, 4-, which by the foregoing operations would have been made to assume a pointed or triangular shape, are niped or creased, and afterwards closed over t e end of the former.

In the machine described in the before mentionedspecification the paper was described as being drawn by rollers from one or more continuous rolls and after being out to length by an intermittently reciprocating knife was fed forward-to an. adjustable mold formed in the table of the machine. The piece of paper after being placed over the mold is carried down into the mold by intermittently reciprocating arms mounted upon a rising and falling shaft carried in bearings upon the framework. The piece of paper after an adhesive material has been apphed to the longitudinal seam of the bag and while in the mold is closed over formers made 1n two parts sliding u on one another and mounte upon the sal reciprocating arms.

Afterwards the end is folded, pressed, and

the adhesive material applied thereto before the bag leaves the former. The same series of operations take place for each former, there being a former mounted upon eachof the reciprocating arms.

In this invention the sheets of paper out of which the bags are formed, are fed separately to the machine instead of being cut from a roll as described inthc first named aforesaid specification. This enables the guillotine or knife for cutting the papers to size to be dispensed with.

a is the table of the machine mounted upon standards or framework 1). The table is provided-with openings for the passage of mechanism for operating the hereinafter described arts.

c is the folding box; (Z the paper receiving table; e the slide that conveys the pa er to the folding box f radial arms mounte upon a shaft f 1 which is caused to rise and fall bV a lever f and cam f mounted upon shaft F. On each of the radiating arms j is mounted a rectangular shaped bag-former, hereafter termed a former 9 made in two parts, one of which parts is fixed to the arm f. 1 1e two parts of the former are made in, say, the form of incline planes arranged so that the upper part of the former will slide upon the '.lower and fixed part, suitable dovetail or other guides or slides being formed therein or thereon for retaining them in the re uired position. The inner end of the up or s iding portion of each former g is provi ed w th a projecting rod f 2 in the inner end of which is mounted a runner f the periphery of which is retained in contact with a fixed cam f through which shaft f 1 slides,by a spring f. The arms 9 are intermittently rotated, say, a quarter of a revolution as hereafter described. h the wiper or front plate; i the cam shaft of the machine, and 1 one of the stays that connects portions of the framework together; 59 the driving shaft of the machine. 0. 1). fast and loose pulleys mounted upon the driving shaft. E a cam for operating the wiper h by means of lever 71 fulcrumed to the pendent bracket E fixed to the table a. F a counter shaft geared to the driving shaft .59 by spur gearing G. H. I. sprocket wheels mounted respectively upon shafts F, i, and connected together by endless chain J. K a vertical shaft geared by miter Wheels L with the shaft 2' at its lower end and having a crank M mounted upon its upper end for imparting an intermittent rotary motion to the shaftf and arms f by means of lever N, lpins N, U, and disk carrying pawl w rich engages with the vertical bars forming a ratchet wheel. 1 an eccentric mounted upon shaft 01 and connected by lever Q, rod R, and

links 5, for operating the slide 0.

All the above described parts may be of a similar construction to those described in the before named specification, and the moving parts may be operated in a similar manner as therein described.

.To feed the said sheets,--which may, or

may not, have printed matter upon them, to the folding box or mold, hereafter termed the folding box 0, the following apparatus or mechanism is employed, namely:-At or about a right angle to the slide 6 that conveys the paper to the folding box 0 of the machine is mounted and fixed on the framework of the machine, say, a pair of standards is. In the said standards are provided bearings for the reception of a air of guide rollers l, m. a The guide rollers m, are arranged to draw'a sheet of paper through them by friction, and one of them, say, the bottom roller, is arranged to apply the paste or gum, glue, or other adhesive rnucilage or material,all of which are hereafter termed and included in the term gum,to the aper as it is drawn through the rollers. T at is to say, the bottom roller m is not formed of one continuous diameter throughout, but is formed or built up in sections of two ormore diameters-as shown at Figs. 4 and 6and of different widths. The center ortion 9 is of the smallest diameter and of t iegreatest width. To the central portion 9 is fixed a metal gum piece or pad n of any suitable shape at its top,say, for example, but not necessarily so, with an upstanding portion in the form, as shown at Fig. 9, that is, with ends shaped somewhat like two Us placed with their bottom portions vertically to each other, but at a distance apart, and connected together by a strip 0 of suitable width,that will supply, say, the gum in position for holding the portions of the sides of the bag when folded together, as follows :The gum is applied to a sheet of paper out of which the fold 1 is produced so that when the fold 2 is turned over and pressed against the end of a former g and on to the fold 1, they are secured in position by the gum thereon in the shape described. The said gum pad a does not extend the full width of the sheet of paper. At each end of and at a distance from the ends of the center portion 9 of the bottom roller, is formed or fixed on the spindle p,the ends of which project beyond the roller,-that carries the center portion, a narrow friction or drawing portion 10 and 11. These last named portions 10, 11, are each larger in diameter than the center portion, but they are slightly above the up er edge 01' surface of the said gum piece n. he friction or drawing portions 10, 11, of the bottom roller are arranged, if so desired, but not necessarily so, to work in watertight compartments (not shown in the drawings), so as to prevent any gum adhering to their peripheries. Another portion 12,a gum or mucilage supplying portion,fo rmed at a distance from the friction or drawing portion 10 of the bottom roller, is provided, and

it is provided with a suitable recess 13 in its periphery. This last named portion is employed for supplying the gum in a narrow are snown at 3.

paper to the folding box 0.

stri to the paper along the portion forming the ongitudm'al scam ol' the bag when on the former g, and therefore at or about a right angle to that suppliedby the gum piece a for the end folds. The recess 13 in the periphery of the port ion 12 provides for the insertion of the sheet of paper, as well as preventing the strip of gum from extending the full length of the sheet of paper. Thesaid gum piece 72 and portion 12 are arranged. to work or rotate in one or more gum troughs g, 1", shown in dotted lines at Fig. 3. The said troughs are provided with one or more adjustable or other scrapers of ordinary construction for removing the surplus gum from it or them. The trough g, 7", may be water jacketed and provided with suitable gas or other heating apparatus for keeping the gum or n'iucilage in a liquid state.

The standards /r are provided with a flat horizontal portion .9 for receiving a pile of sheets of paper; and also with an incline 15 down which the sheets are fed separately to the rollers Z, or. ()n the incline t are provided one or more adjustable guides u so that each sheet of paper may be fed accurately to the said rollers and gum applying mechanism. and in front ofthe said rollers two hearings in the form of brackets '12 are fixed to the framework 7). In the said brackets o a spindle or short shaft w is mounted so as .to be capable of oscillating freely. On'the said spmdle'w a number of partly curved lifter brackets 92 aremountcd and fixed at convenient distances apart. Two of such brackets To each of the brackets so a long narrow strip of metal, or wood, or other material is fixed to form the fingers of an oscillating lifter grid 2 that receives the paper as it issues from between the rollers Z, or, and gum apparatus a. The oscillating grid conveys the paper as it issues from the rollers Z, or, to the slide 2 that works on the table d and in connection with the foldmg pox c. The lifter grid 2 is arranged durmg its oscillatin motion to turn the paper over so that when a shoe 31 of paper is deposited upon thesaid slide the gummed side u pcrmost. The action of the slide is Sllllllill to thatdescribed in the hereinbefore mentioned specification for conveying the The formers g are in a raised position when the sheet 31 of paper is laid over the top of the folding box.

The above described parts are arranged to be operated follows :The rollers Z, m', are so geared as to remain stationary, say, for

about three-fourths of a revolution of the driving or other convenient shaft of the machine, say, the cam shaft 'i, and during the remaining, say, one-fourth of the revolution of the said shaft tire rollers make a complete revolution for drawing in, gununing, and de- At a suitable distance front 14 is mounted one of a train of spur wheels 15 to a shaft or spindle or pin (a spindle 16 is shown at Fig. 4) carried in a suitable hearing or bearings 17 fixed to the framework. On the spindle 16 which carries one of'the spur wheels 15 mounted thereon, is a star wheel 18, or Geneva stop as it is sometimes called. The star wheel 18 is fixed t0 the said spur wheel, and it is provided with, say, four slotted arms, one of which is arranged to engage a runner or pin 19 on a disk 20 provided on one side thereof with a projecting rim or ring 21. The diameter of the rim or ring 21 is such that it fits the curves between each of the slotted arms of the star wheel. The disk 20 is mounted and fixed on a shaft 23 carried by brackets 24 fixed to the framework, and it receives motion from any rotating part of the machine, such as drivin'? or fixed (adjustably or otherwise) a spur-seg-" ment 29 which gears with a spur wheel 30 mounted and fixed upon the same spindle w that carries the grid finger lifter brackets 95. When a second sheet of paper, which is usually of a smaller size than the hereinbefore first mentioned sheet 31, is required to be used as, say, a lining for the bag, then it may be fed to the folding box 0 after the first sheet has been conveyed thereto by the hereinbefore mentioned slide e and placed upon the first sheet before the latter passes into the folding box, whereby the two sheets are folded together simultaneously. The mechanism for feeding the second sheet is arranged as follows :On the framework b and at or about a right angle-or in any other suitable position to the longitudinal length of the folding box a, is a small framework 32 (Figs. 10, 11, 12) provided with a small hopper 33 at its top into which a sheet of paper is deposited by hand, or by any other suitable means. In the framework 32 carrying the hopper a horizontal slide 34, working in suitable guides,is arranged to be intermittently reciprocated for carrying the second and slightly smaller sheet of paper over the folding box after the first sheet 31 has been conveyed thereto.

v said slide is also slotted or bifurcated at 36 and lug 43 to the said slide 34.

" attached a hingedfiap or lever 44 (Figs. 13,

The said slide is arranged to work immediately under the lower orifice of the hopper, and it is provided with a recess 35 at its 1111181 end for receiving the second sheet that requires to be conveyed to the folding box a. The said horizontal slide 34 may, when re-' quircd, be made to rise in its guidebut such is not shown in the drawingswhile the former is descending into the folding box to prevent gum adhering to the underpart of slide. The front or inner end of the to permit a former g passing into the folding box 0 and carrying the papers with it. An intermittent reciprocating motion is imparted to the said slide 34 from a barrel or other cam 37 ,mounted and fixed upon, say, the former cam shaft t',through a lever 38 mounted,so as to work freely, at its lower end on the pin 39 of a fixing 40 attached to one of the stay rods of the machine. The upper end of lever 38 is connected at its upper end by a link 41, pin 42,

When a sheet or piece of paper is folded into a bag with, say, the edges of its longitudinal fold (when on 'the"former g) at or near one of the edges of the said former, instead of at or about the center of the latter as in the hereinbefore mentioned specification, then in addition to holding it in position at one point by the wiper plates h, as in the aforesaid specification, to the arm f carrying the stationary portion of each former is 14, 15), for holding the folded edges of the paper securely in position. The said flap or lever 44 is suitably shaped and curved, as shown at Figs. 13 and 14, and it is mounted upon a pin 45 arranged to pass through lugs or projections 46 fixed to the arm f carrying the stationary portion of the former. To the underside of the flap or lever at its front end is fixed a piece of india-rubber 47 for enabling the flap or lever to bed itself to its work and also to tightly hold the folded portion in position. At or near the opposite end ofthe underside of the flap or lever 44 is provided an incline or cam piece 48. Projections 49, 50, are also provided respectively on each of the longitudinal edges of the flap or lever 44 at a suitable distance from its joint or hinge for purposes to be presently described. Upon the upper surface of each of the said projections the free end of spring 51. coiled round the pin 45 is made to work for retaining the [lap or lever in a closed position. The said flap or lever is operated for raising the same and causing it to turn upon its hinge,\ .'hen the former has been rotated into position for passing into the folding box 0 prior to the upstanding portions of the sheet or sheets being folded'over by their respective wipers,-by a vertical is fixed to the table a of the machine,-connected by a link 54, and fixing 55 to the end of a bell crank lever 56,'fulcrumed to a bracket 57vWl1iCl1 is fixed to the table.

The lower end of lever 56 has fixed to it a runner 60 which works against a cam 58 mounted say, upon the shaft 59. The lever is actuated by the cam for intermittently raising the pin 52 employed for operating the lever or flap. As the said vertical pin 52 is raised it is made to come in contact with the incline or cam piece 48 formed upon the underside of the flap or lever 44, and thereby raises the front end of the same. The operating cam 58 is so timed to act upon the bell crank lever 56 that the flap or lever will be allowed to descend upon thefolded paper as soon as the Wipers hhave folded the paper on the former. The arm f carrying the former g is then raised out of the folding box 0 and rotated for permitting the end of the bag to be folded. The flap or lever 44 is retained by the ends of spring 51 in a closed osition until the bag is ready to be removed rom the former. When the point at which the bag is to be removed from a former is reached, as the arm f carrying the former descends, the projection 50 on the flap or lever 44 is made to come in contact with a vertical pin 61 carried by a bracket 62 which is fixed to the table which raises theflap or lever for releasing its hold upon the bag. The intermittently reciprocating vertical pin 52 is arranged at or near the folding box 0 and the fixed pin 61' at the bag discharging point 93 as shown at Fig. 12. A separate flap or lever is provided for each former. The whole of the flaps or levers are operated upon by the

ins

52 and 61 as the folding box and bag ischarging points are respectively reached.

To fold the ortion of the sheet or sheets, what is termed the bag is being made on the former,but which is really the vertical seam of the bag when in use,and which according to this invention is folded a short distance over the edge of the fformerf the mechanism is arranged as follows :To the underside of the existing front wiper or folding plate 7L, which works in the guides 65, is connected, by a link 63, (Fig. 20) a closer plate 64, as shown at Figs. 20 to 22. The closer plate is formed at its center, in cross section, somewhat like an inverted letter L, and it is mounted on a pin 66 carried in bearings 67 attached to the guides 65 below the front wiper or folding plate It. The guides are fixed to the table a. The front portion of the closer plate 64 is made to extend the full length of the formers and to project each side of the guides 65 to which it is jointed. The link 63 is attached to a projection 69 formed at the back of the closer plate. ()n

pin 52,carried in suitable bearing 53 which the underside of, and at the required dissenate tance from the closer plate 64 is a projection bottom.

68 which extends the full length of the said plate. The said projection rests upon the upper'ejdge of the folding box cwhen the closer plate has been moved into position for foldingthe longitudinal seam, as shown at Fig. 20, for enabling a recess to be formed,

To supply thegum for securing the two side lugsifl, 4, to the bottom portion of the bag after the'top and bottom folds 1, 2 have been closed and the two side lugs have been creased and folded ready for closing, a bracket 72- (Figs. .23and 24) is fixed to the fram'eworkb. On the top of the bracket the gum box or pot-7 3 is mounted and fixed with or without aheating arrangement of any ordr nary'construction. The gum box of pot in ay, or may'not, be partially covered at the top. To one of' the brackets 74 to which the levers 75, 7 6,'-carrying the end wipers 77, 78,-are fulcrum'ed,asinall bracket or hearing 79 is fixed to which. a suitably shaped. double ended lever 80 is fulcrumed and arranged to work in a vertical position. The lever 80 is actuated at its lower end by a cam 8-1. mountedupon, say, the same shaft i-that carries the cams S2, 83,-for operating the end wiper lovers.- the end of each lever in contact with its operating cam. "The upper end of the lever 50 is connected by a link to a suitably sha 36d curved. and cranked lever 86 which is fulcrumcd to a fhring or arm 87 which is either formed on or attached to the bracket 7 2 which carries the gum box or ct 73. On the inner face of the'upper end of lever 86 are provided projections (Fig. 24) shapedsomewhat like the letter H for applying the gum inth'is shape to the end folds l, 2, of the bag. i The free or upper end of the lever 86 is so arranged that when it is tilted over by the double ended lever SO'rt will dip the gum box or potfo'r raisingthe required amount of guin-tllatds requlredto be "placed and dcpositedj by "it,-when" it isi'aisedfrom the gum b'om cn 'tothe folded portions 1, Zfcf the bag ilp'onthe end of the former.

To sccuretheend fold l-of'the bag properly closed and formed, below the bracket 90 carrying theend"foldcrlll'is provided and fixeda p'late'88f, shown at Ei sQ27to'29. Fronithe'side of'the plate'SS span of horns S9 is made to project both outwardly and upwardly.- The inner face of each of the horns 89 is made to taper downwardly, that is to say, the space be een l e inner faces of the two horns 89 larger at the top than at the A spring 84 is employed for keeping This tapering of the horns enables the l'clder'ill as it descends between the horns to crease and fold the paper to the required form for more perfectly folding as well as they may be arranged to operate in a similar 5 manner.

The action of the above named several parts is as follows :--"he sheet 31 of paper which forms the main portion of the bag is passed down incline t to the rollers Z, 'm, 5

where it is guinincd by the pad n and portion 12,on to the finger e by which it is turned over and carriei'l to the table (Z to be conveyed by the slide 6 to and over the folding box 0, but under the raised arms) and formers g. After the slide has been withdrawn and when a second paper lining is required this is placed in the hopper and falls into the recess 35 of the slotted sli le 34. The slotted slide conveys the second sheet over the fold- 5 ing box immediately after the first sheet 31' has been deposited. there by the slide 0. The

armsf are then caused to descend carrying with them one of the formers 51 through the slotted slide 34 into the folding box 0. At

the time the sheets of paper are carried dm 1 ii s the folding box, they are wrapped around. tnc underside and the two sides of the former with the paper projecting on each side above its upper surface. When the former has descended into the folding box 0 the vertical pin is caused to rise and fall for raising the front portion of the flap or lever 44 to permit of the upstanding portions of the sheets being folded on to the top of the former and acted upon by wiper plate 94 and closer plate 64. After the wiper plate 94 has been operated and while the closer plate 64 is still in contact with the folded sheets,

'tl e flap or lever 44 is allowed to descend for 1position .upon the lpglding' the paper in iormei until the end or'ming the bottom of the baghas'beencloscd. The "fornier is then m s'ed out'of the folding box and rotated to position-92 (Fig. 12') when it is again made for forniii'i fold l. The former is a ain 120. i to descend against the horns 89 and to be afterwards acted upon by the end folder 91 former, the free end of the flap or lever 44 is raised by the fixed pin 61 and the bag ejected from the former.
