CARTON FILLING AND sEALiNG MACHINE Be it known that I, GILBERT F. HELSON,

a subject of the King of Great Britain, but having declared my intentions of becoming a citizen of the United States, residing at .Bay Side, in the county of Queens and State of New York, have invented an Improvement in Carton Filling and Sealing Machines, of which the following isa specification.

My invention relates to machines for fillmeans for holding the cartonsand carrying them in the same plane over thebed of the machine; to provide means for first folding and sealing the bottoms of the cartons while being carried forward; to provide means for filling the cartons after their bottoms have been folded and sealed; to provide means for foldin and sealing the tops of the filled cartons, and to provide means for discharging the completed packages from the holders and delivering the same to an attendant for packing.

The details of the invention \are hereinafter particularly described, and illustrated in the accompanying drawings,'forming a part hereof, in which.

These two bars are each rigidly secured to the vertical members 13.

tending the entire length of.their straight as C the hopper cut-off l a plan of thedriving mechap I I In the facing surfaces of the respective bars, there is a longitudinal groove 17, ex-'.

sidep'ortions, the outer wall of the groove 'being, removed upon the semi-circular ends to permit ofthe free passage of the guide plates hereinafter described. 18, -den0tes a sprock t chain, to the outer side of" which are connected at equally spaced intervals, vertical ide plates .19, in any suitable manner, pre erably by means of short arms 20, and rivets 21.

its center is a hub 76, having an integral carton pass off the plate 67, and approach the plate 69, the front end flap of the carton contacts with thetapered end of the plate 69, r by which it is folded inward of the carton, and at the same moment the lower rear end flap of the carton is also folded inward by 75 and having an upper support secured to the-bar 14'. Keyed to the shaft 74, at about projection or lug 7 7 Surrounding the shaft 4, between the hub 76, and the bearing block 75 is a spiral spring 78, one endof which is secured to the stationary bearing 7 5, the other end being secured to said hub. 79, denotes another bifurcated lug secured tothe top of the bed 10, in which is pivotally secured one end ofa link 80, the other end of said link being pivotally. connected to one end of a longer link 81, which at its other end is pivotally connected to the arm 71.: I

82, is a connection rod between the lug 77, on the hub 76, and the link 80, having a pivotal connection with each of these members. 83, is an arm extending at right angles from the shaft 74, one end being keyed to said shaft at its top. A wheel 84, is attached to the free end of the arm 83, by a pivot pin 85. The wheel 84, comes into contact with the rear surface of a passing carton holder, which ,forces the wheel away from the holder, thereby giving the shaft 74, a partial rotation, contracting the spring 78 and by means of the connection rod 82,

l .and links 80 and 81, the folder arm 71 is drawn up into a vertical position, during which movement its head strikes the lower rear end flap of the carton contained in the holder, folding it inwardly. The forward end of the head of the arm 71 is preferably rounded, so that it will not injure the flap when striking it and'will bear uponits surface smoothly. As soon as the wheel 84, loses contact-with the carton holder, the compression on the spring 78, is released thereby allowing it to expand which throws the kicker or folder arm 71, back to its normal position, until the next carton holder contacts with the wheel .84, when the arm 71, will againbe operated-as before, Whichaction is repeated so long as the machine. is being operated. The details of this mecha-' nism is most clearly illustrated in Fig. 4 of the accompanying drawings.

As the carton holder advances, the two folded lower end flaps of the carton contained therein, ride u on the plate '69, as do also the two lower side flaps, but in conse- .bed 10.

quence of the broadened width of the plate 69, to therear of its tapered end, these two side flaps are spread outwardly "into horizontal position while passing over the upper surface of said plate.

Adjacent the rear end of the spreadbr plate 69, there is a glue roller 86, mounted upon a transverse shaft 87, journaled inbea'rings 88, secured to the top of the side walls of a glue receptacle 89, which is seated upon and secured to the bed 10, in any suitable manner.

Upon the inner end of the is fixed a sprocket90.

91, is another transverse shaft in vertical alinement with the shaft 87, upon which shaft 87, there there is fixed a sprocket 92, inthe same i alinement with thesprocket 90. A chain belt 93, passes over and connects these two pulleys. The shaft 91 is journaled in bear--- ings .94 secured to the underside of the 95, is another transverse shaft spaced from and parallel with the shaft 91,. on the same plane and journaled in similar bearings 96. A sprocket chain 97, passes between the . shafts 91 and 95, and engages asprocket wheel keyed to each of said shafts.

98, is a sprocket wheel keyed to the shaft 95, and 99, is a similar wheel keyed to the shaft 53; a sprocket chain 100 passes over and engages these respective wheels. By means of these sprocket and chain connections the glue roller 86 is continuously r'evolved while the motor 41 is operated.

When the outwardly spread lower side flaps of the cartons reach the rear end of the spreader plate 69, they pass over the pe- I riphery of the glue roller 86, and receive a thin coating of lue upon theirunder surfaces. As these orizontally and outwardly spread side flaps pass olfth'e glue roller, they are engaged by a pair of folding members 101 and 102,}whichare so disposed w th relation to each other that one ofthe side flaps is first folded over upon the top ef the previously folded end flaps, to w ch t ad heres' by'its coating of glue, and then the opposite and remaining glued side flap is folded over upon the top of the first folded.

side flap, thus completely sealing the bottom of the empty carton. i

curved in such manner as to turn the side flaps over and press the same against the previously folded flaps.

These folding members 101 and 102, are

The member101 is supported by an up- 1 right 103, secured to the top of the bed 10,

bar 15, by screws 'or rivets 104.

To prevent any possibillty of while the member 102 is secured to the guide.

the cartons being pushed up in the holders, during the folding and sealing of the bottom flaps, I rovide acomparatively narrow fiat strip 05, which is secured along one edge to the top of the bar 15 by rivets or screws or in another suitable manner, and projects silightly over the side of said her for a predetermined distance. That end of this strip 5 nearest the approaching carton holders is bent slightly outward from the bar 15, and curved in such manner that its free end first contacts with the front top end flap of a carton and then with the innerside flap which it turns outward and guides under the strip 105, where such flap travels during the folding and sealing of the bottom flaps of the carton, after which said flap passes from under said strip and assumes a vertical. or nearly vertical position; it is not creased by said strip but merely held with suhici-ent top pressure to prevent the carton rising in the holder while the bottom flaps are being acted upon, and springs back to its first position, as does the end flap when released from the strip 105.

106 is an elongated plate, supported by the standards 10?, secured to the top of the bed 10. This plate is located adjacent to and in alinement with the folding members 101 and 102, so that when the cartons pass the side flap folders their folded and sealed bottoms ride upon said plate, from which they pass upon another support 108, which is supported from the bed 10, by upri hts 109..

T is member 198 extends along t e other side of the machine a greater distance, being curved to conform to the end curveguide bars i i and 15;, end is omposed of a flat strip in order 9 prevent interference with the working of he filling measuring mechanism at this r l i he machine, These supports 106 end lded and sealed bottoms of the e the thorough setting or dry paste or glue before the cartons pass off said support 108.

The movement of the star wheel 52 is so timed that at each time it comes to rest one of the carton holders 22 containing one of the cartons 66 with its bottom rieps. folded and sealed, has been brought directly under and in register with a funnel 110, contain.- ing a measured quantity of the filling rial which is discharged into such carton the next movement of the sprocket chain 18, carrying said filled carton past the til." funnel and bringing the next cert-on h. with its contained. carton register "v the machine is being operated, J

The details of the measuring and mechanism. will be next described,

111., denotes a hopper for holding the ding material 1152 to be supplied to the can tons. This hopper is supported at t e right hand end or" the machine, a predetermined distance above the bed 10', by and between two posts 113 the lower ends of which are bolted or otherwise fastened to the bed, one

said funnel, and so on continuousl newness adjacent each side at this end of the mechme. The upper ends of the posts 113,'are secured to the ends of the arms 114, projecting from the hopper at opposite sides, by bolts 115, i

116, indicates a vertical shaft supported at its upper portion in bearings within a sleeve 11?, to which is secured one end of a horizontal bar 118, the other end of which is secured to e yoke 119, connecting the posts 113. This shaft 11.6, also has a hearing beneath the bed 10, in. a bracketiQG, secured to the underside of the bed. 7

Keyed to the bottom end of the shaft 116, is e bevel gear 121 which meshes with a bevel gear 122 keyed to the longitudinal shaft 123, the ends of which are journcled in the hangers 12 i, and 125, secured to the underside of the bed. There is a bevel gear 126 keyed to the shaft 123, which meshes with s bevel gear 127, keyed upon the inner end of the transverse shaft 53. It will therefore be seen that the longitudinal shaft 123, will be continuously rotated while the motor is running, as will also the vertical shaft 116.

Upon the upper end of the shaft 116, is fixed e smell bevel gear 12?" which meshes with a similar gear 128, fixed upon one. end of a horizontal shaft 129 rotating in bearings 130, 131 supported by the member 132- at the top of the hopper 111 to which it is secured by rivets 133,

The member 132., has an integral horizontal arm 13%, extending to the center of the hopper 111, and is provided the end with a hole through which extends the upper end of a vertical shaft 135, fitted in a bearing 1%, and having secured to its lower end a plurality of agitator blades 13?) Upon the extreme upper end of the shaft 1%5 is keyed.

a smell bevel gear 138, which meshes with a similar gear 139 upon the other end of the horizontal shaft 129 it will be seen that the agitator shaft 135 end blades 13? will be continuously rotated during the retation of the vertical sheit 116 The hopper 111 is preferablytapered from top to bottom and at e certein distense from its bottom is provided with an integral. horizontal projection 140, which extends on one side in substsntislly recten guler form for e predetermined distance.

Bearing against the under surface oi the plate or projection 140, end of shape therewith another plate 142; two

plates being secured together around their outer edges by screws or bolts M 3 The plots 142 is provided in its upper surfsce with e longitudinal groove or recess 14%, within which is slidebly titted a shut oh" plate 1 5, there being a slot i l-6, in one side of the hopper 11.11. through which said shutoff plate pass. This shutoff plate is connected to one end of s rod 14?; which passes through en opening in the pistes and Bil members 141, arranged at either side of the 'plates 140 and 142, is an angle piece 149,

there being a vertical slot in the upright end portion of said angle piece through which the rod 147 passes. The other end of said rod extending through a hole in the upright support 150, the flanged lower end of which is bolted to the bed 10. There is a collar 151, keyed to the rod 147, and between this collar and the upright end of the angle piece 149, there is a spiral spring 152, surrounding the rod 147.

A stop nut 153 upon the rod 147 limits the movement of the rod between the-boss 148, and angle piece 149.

. Upon the extreme end of the rod 147 there is fixed a pair of jaws 154, between which a wheel 155 is pivotally secured by ,a pivot pin 156.

157, indicates a cam keyed to the vertical shaft 116, at ,a point in alinement with the rod 147.

This cam contacts with the wheel 155, each revolution of the shaft 116 compressing the spring 152, and pushing the cut-ofi plate 145 through the slot in the side of the hopper, thus shutting off the discharge of the filling material from the hopper, until the cam passes ofi the wheel when the shut-off plate is withdrawn from the hopper by the expansion of the spring 152, allowing the discharge of the filling material to proceed until again shut ofi 'by the contact of said cam with said wheel.

When the shut-off plate 145 is in the position shown in Figs. 1 and 12, it may be re tained in such position for any desired length of time, whether the machine is in operation or at rest, by means of the latch 158, one end of which is hinged or pivotally connected to the bar 118, and can be, swung down behind the collar 151 as illustrated in dotted lines, preventing any movement of the rod 147, while it is thus positioned.

1 159, is another upright having its flanged lower end bolted to the bed 10, and provided with a right angled to 160, extending to the upright 150, to which it is secure bolts or rivets 161 or in any suitable manner. There is a circular opening in the horizontal member 160, through whichthe vertical shaft 116 passes.

The extreme lower end of the hopper 111, is outwardly flared or flanged as at 162, (see Fig. 14), and is fitted within an interior annular gi'eoove 163, in' the top of a measur r 164, provided with ears or lugs ing cham 165 on its exterior.

This chamber 164 is and about midwav of its length; the lower portion is somewhat contracted, and provided with a screw thread on its exterior, which connects with aninteriorl'y threaded portion of. a

short tubular inember166.

Atthe lower end this tubularsecti on,

180, through which the vertical shaft 116 passes of said 7 w t racts,' pushing the cut-off plate 172,- back 'overithe top of the tube-168, and closing the the plate 169, bearin against the under surface of the plate 16 the two plates being secured together by bolts or screws 170, around their outer edges. c.

The plate 169, is provided in its upper surface with a longitudinal groove or recess 171 extending from the outer end of said plate to the interior of thetube 168.

Slidably fitted within this recess or groove is a cut-off plate 172, connected to a hub 173, upon one end of a horizontal rod 174. This rod passes through a vertical .slot in the upright 150, and has a bearing '175, in the upper end of a vertical member 176, secured to the upright 150, by a bolt 177, which passes through said vertical slot in the upright, said rod and bolt'beingcapable of vertical movement in such slot.

The end of the rod 174, projecting beyond the upright 150, is fastened to the vertical inner end 178 of a horizontal plate179, in which there is a central longitudinal slot passes. At the outer end of the plate 179, and extending downwardly from its underside, is connected a roller 181, by a pivot pin 182.

Surrounding the rod 174, between the bearing 175 and hub 173 and connected at its respective ends therewith, is a spiral spring183.

184, indicates a cam keyed to the vertical shaft 116, immediately beneath the plate 179, which cam contacts with the roller 181, ateach revolution of the shaft 116.

'llhe action of the cams 157, and 184', on the respective cut-oils are the reverse of each other, that is, when the cam 157, contacts with the wheel 155, it compresses the spring 152, and forces the cut-ofi' plate 145, into the hopper, shutting of the feed of filling material, and when said cam passes ofisaid wheel the spring'152 expands withdrawing rod 174 is drawn outwardly, the spring 183, i x

expanded and the cut-off plate 172, withdrawn from the tube 168, and when the cam roller, the spring 183, conbottom of the'tilhiilar member 166. 1 i Y The cams 157, and 184, are positioned upon the shaft 116, so that the respective shut-offs are operated alternately, that is, when the upper one is closed, the lower one is open, and when the lower one is closed, the upper one is open.

The details of the lower cut-off are most clearly shown in Fig. 13, of the drawings.

The vertical tube 168 extends into a cylinder 185, through a short tube 206, projecting at the top of the cylinder which is secured to the plate 169, and the lower open end of said tube is in alinement with the open top of the funnel 110, which funnel is located within said cylinder, being secured to one end of a lever 186, fulcrumed at 187, outside said cylinder, said lever passing through a vertical slot in that side of the cylinder, which slot is open at the bottom as is the bottom of the cylinder.

The other end of the lever 186, is pivotally connected to the upper end of a vertical rod 188, which is located within a tube 189, the bottom of which is secured to the top of the bed 10. I

Surrounding the rod 188, within the tube 189. is a spiral spring 190. The rod 188, extends through an opening in the bed, and its extreme lower end is bifurcated within which is secured a wheel 191, by a pivot pin 192.

193, indicates a cam keyed to the shaft 123, at a point in line with the lower end of the rod 188, which cam contacts with the wheel 191, as the shaft 123 is revolved, thereby forcing the rod 188, upward against the action of the spring 190, raising the outer end of the lever 186 and lowering the funnel 110, at the other end of the lever into the position shown in Fig. 1. As the cam 193, passes 06' the wheel 191, the spring 190 contracts, drawing the rod 188 downwardly, which elevates the funnel 110 a certain degree within the cylinder 185. This occurs while the earn 184: is acting upon the wheel 181, which withdraws the cut-off plate 172, from between the tubes 166 and 168, allowing a measured quantity of the filling material contained in the measuring chamber 164, to discharge into the funnel, the upper cut-off in the bottom of the hopper 111, being at the same time closed by the action of the cam 157, on the wheel 155. hen the cam 193 again contacts with the wheel 191, the funnel is lowered with its contents directly over the open top of one of the cartons 66, which at that moment has come to rest in such position, while the lower out- 011' has been closed, and the upper cut-ofi opened by the action of the respective cams 18 i and 157.

The quantity of filling material to be delivered into the cartons, isregulated by rotating the measuring chamber 164:, which may be readily done by hand, the lugs or enses ears 165, beingpreferably provided on the exterior of such chamber or facilitating this operation. By the rotation of the chamber 164, in one direction the tube 168, is drawn upward, and when said chamber is rotated in the reverse direction, said tube is lowered; such movements, of course, also either raise or lower the plates 167 and 169 with the cut-off plate 172, and parts connected therewith, the rod 17-1- and its bearing moving in the vertical slot in the upright 150, while the guidemembers 141 slide against the opposite sides of the plates 110 and 112. The roller 181, must be of such width that the can) 184, will contact with it at each revolution of the shaft 116, whether the lower cut-01f is in a raised or lowered position.

The continued intermittent motion of the sprocket chain 18 carries the carton holders containing the filled cartons to the other side of the machine with the sealed bottoms of the cartons still riding upon the supporting strip 108, which is extended on that side of the machine a distance to support the filled cartons while their top flaps are being folded and sealed.

194-, indicates another folder and spreader plate, similar to the plate 69, on the other side of the machine, as heretofore described. The plate 194, is secured to the top guide bar 15, in any suitable manner, and its tapered end in the direction of the approaching carton is preferably slightly curved upwardly so that the first top end flap of the carton with which it contacts is folded inwardly and downwardly under said plate, and as the carton advances its side flaps are spread outwardly by said plate at right angles to the vertical walls of the carton.-

As the carton holder passes beneath the plate 194, it comes into contact with a wheel 195, which bears upon the outer surface of the inner side wall of the carton.

This wheel is pivotally connected in a horizontal position to one end of a short arm 196, extending from a hub 197, keyed to the top of a vertical shaft 198, which is rotatable in an upper bearing secured to the rail 11, and has a bottom pivotal hearing at 199. That portion of the shaft 198, below the rail 14 is surrounded by a spiral spring 200, the lower end of which is secured to the bearing 199, and its upper end to the shaft.

The contact of the wheel 195, with a carton holder forces the wheel outward from the carton, thereby moving the arm 196, and partially rotating the shaft 198, against the action of the spring 200. Integral with the hub 197 there is another arm 201, extending at right angles to the arm 196 and of somewhat greater length than that arm.

202, is another vertical shaft spaced a certain distance from the shaft 198, its lower end being fixed at 203, upon the top of the bed 10, and its upper end fixed in a bracket 204 fastened to the rail 15, by a bolt 205.

207, is a kick lever, fulcrumed upon the shaft 202, the rear arm 208,- of said lever being pivotally connected to a link 209, the other end of said link being pivotally connected with the other end of the arm 201. The free end of the lever 207, is provided with a toe 210, the end of which is preferably rounded as shown. (See Fig. 8.)

At the same time that the folder and spreader plate 194,1-is folding inward one end flat, and spreading the two side flapsof a filled carton, the wheel 195, is in contact with one side of the carton holder containing said tilled carton, whereby through the action of the arms 196 and 201, and link 209, the kick-lever is swung into the position shown in broken lines in said Fig. 8, coming into contact with'the other end flap of said carton and folding it inward as 'illus-.

trated in broken lines in said Fig.

When the wheel 195 passes off said carton holder, the lever 207, is drawn back to its normal position shown in full lines in said Fig. 8, by the contraction of the sprin 200.

The outwardly spread side flaps o said filled carton pass from the rear end of the spreader plate 194, under a glue roller 211,

mounted upon a shaft 212, which is journaled in brackets 213, secured upon the top of the bed 10, by bolts 214. 215, denotes a glue reservoir, supported upon a bracket 216, secured to the brackets 213 by bolts 217.

. This glue reservoir has an open concave ously revolved while the machine is in o end adjacent the glue roller closes.

There is an adjustable bottom plate 218, fitted in the glue reservoir, the front edge of which plate is preferably beveled and is adapted to engage the surfer of-the glue roller, or to be adjusted to any desired de-.

and 222, similar to the folders 101 and 102,

on the opposite side of the machine and hereinbefore described, and act upon the side flaps at the top of the carton, in the same manner that the others act upon the side flaps at the bottom of the cartons, that is, these folders 221 and-222, are so disposed with relation to each other that one of,the

side flaps is first folded over upon thetop of glue roller 211, which the eyed upon the glue the previously folded end flaps to which it adheres by the glue it .received from the glue roller,'and thenthe opposite and remaining glued side flap is folded over upon the top of the first folded top side flap, thus completely sealing the top of the filled carton. These folders 221, and 222, are connected at one end to the top bar 15 of the guide frame.

The sealed cartons as they leave the folders 221 and 222, are carried under an elon gated fiat strip or plate 223, fastened along one edge to the topbar 15, by rivets or in anyv suitable manner. Thisplate holds down the last fold of the side flaps for a certain distance to assure the setting or drying of the glue. Adjacent that end of the plate 223, where the filled and sealed cartons pass from under it, the re is provided means for ejecting the filled and sealed cartons from their holders, whichwill next be described.
