In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

The machine illustrated is a double machine, that is, a double set of mechanisms are provided so that two strips of paper are fed into the machine and the containers or receptacles are formed by two sets of mechanisms, but as these are substantial dupli- "paper and the paper feed rolls.

cates, only one set is illustrated. The, turret, however, and certain other features are common to both sets. r

The means for supporting the rolls; of paper and feeding them into the receptacle blank I forming and receptacle forming mechanism is shown. in coacting relation thereto in Fig. IV, Sheet 4, the blank forming and receptacle forming mechanisms be ing indicated conventionally.

For convenience I use the term paper in the specification and claims but I wish to be understood as usin the same in a broad sense and as incluc ing any suitable material, fibrous material or fabric, for forming the receptacles.

Stated generally my improved receptacle or container forming machine comprises means for supporting and feeding paper from a roll, means for forming body blanks or body strips from. the roll of paper, means for delivering the blanks to forming mandrels, and applying adhesive to the blanks as they are wound up in the mandrels, means for feeding container'bottoms so that the convolutely wound bodies are wound upon the same, means for applying adhesive to the bottom and crimping and upsetting the bodies on the bottoms, means for crimping the tops to receive the cover flanges, and means for ejecting the several operations being automatic.

I have for convenience in description designated as the front of themachine the end from which the strip of paper is fed thereto. The term is, however, more or less arbitrary. For clearness in illustration, I have, in various figures, shown parts removed from the machine and have shown the part or parts in connection with certain coacting parts in order that the details may be clearly understood. Many of these parts may, however, be greatly varied in structure, and I have shown the details thereof mainly for the purpose of clearly illustrating a structure which I have found practicable and to enable others to embody the invention in practical working structures.

Referring to the drawing, I provide a frame, designated generally by the numeral 1-see Fig. IV, Sheet 4, for the paper feed mechanism adapted to support the rolls of However, as details of this frame form no part of this invention they are not described herein.

I provide a separate frame 2 for the container blank forming and container forming mechanism, this frame being adapted to support various parts in their proper coacting.

relations. However, as the details of this frame form no part of my present invention, I do not describe the same herein. Referring to Fig. IV of the drawing, the rolls of paper 3 are mounted upon spindles 4', there being a spindle 4 at the front and rear ofthe frame 1 and the spindles. proj ecting to receive rolls on either end.

From the roll 3 the strip of paper 5 is passed between feed rolls 6 and 7 supported by the bearing pedestals 8. The paper passes to these feed rolls through a guide'9 mounted on the pivot 10 and provided with a counterbalance arm 11 having an adjustable Weight 12 thereon-see Figs. V and VI,

Sheet 4. This counterbalanced guide swings to accommodate the roll when mounted on either the front or rear spindles. The object of the pair of spindles is that a roll may be arranged on a spindle while the paper is being fed or drawn off from the roll on the other spindle, and when the roll on one spindle is exhausted its end is attached to the end of the paper on the other roll so that it is not necessary to thread up the machine.

The feed roll 6 is a driven feed roll, its

shaft 13 being provided v with a beveled gear 14 meshing with a gear 15 on the shaft 16 driven from the main mechanism of the machine as will be later described; The shaft 17 of-the feed rolls 7 is carried by floating bearings 18 held yieldingly downward by the coiled springs 19.

It is sometimes desirable, as for instance, when adjusting the paper or feeding up the machine, to raise the pressure rolls 18. To accomplish this I provide an adjustable support for the shaft 17 consisting of the hanger 20 engaged over the cross rod 21 at the upper ends of the bearing pedestals and having an arm 22 pivoted on its lower end at 23.

A wedge-shaped slide 24 is mounted on this arm, the slide being slotted at 25 to en gage a notch 26 in the hanger. The slide is secured in its adjusted position by means of the screw 27 engaging the slot 28 therein. A very slight adjustment is required of this slide to raise the rolls out of feeding engagement with the paper. 1 From the feed roll the paper passes through a steam chest 29. The steam connections for this chest are, however not illustrated. The paper is treated with'steam to render it more flexible, certain grades, however, do' not require this steam treatment. These parts are shown in detail in Figs. IV, IV and V, Sheet 4.

From the steam chest 29, the strip of paper passes through the guide'30see Fig. II, Sheet 2, Fig. IV, Sheet 4, and Figs. XVI

and XVII, Sheet 9to the cutters or blank forming dies-see also Fig. XVIII, Sheet 5, in which the relation of the strip to the dies is illustrated.

The dies or cutters are adapted to cut the strip of paper 5 into blanks or strips .of

converging or diagonally disposed cuts or slits 31. There are uncut portions 33 at each si e of-the holes 32 so that the paper is'still carried or fed along as a continuous strip after being operated upon by the dies or cutters.

By thus forming the slits the blanks are provided with tapered front ends and correspondingly recessed rear ends, the advantage of which will appear later.

The die 34 is mounted upon a fixed support 35 on the frame 2. The die 36 is mounted upon the movable die plate 37. The movable die plate 37 is mounted on a reciprocating carriage 38 supported in the ways 39. The carriage is operated through a pair of toggles 40 one member of each toggle being pivoted on the frame at 40" and the other being connected to the carriage or die plate. These toggles are connected by the link40' to the link 41 on the rock shaft 42. The shaft 42 is provided with an' arm 43 to which the link 44 is pivotally connected, the link being slotted at 45 to engage the camshaft 46 having a cam 47 thereon coacting with the roller ,48 so that as the cam revolves the die plate carriage is actuated.

he springs 49 connected to an arm 50 on the rock shaft 42 and to the frame return the carriage. The rock shaft is provided with a lever 51 so that the dies may be manipulated by hand. These parts and their relation to the machine are shown in Fig. II,

Sheet 2, Figs. XVI and XVII, Sheet 9, and

Fig. XVIII, Sheet 5. The driving connections for the cam shaft '46 will be pointed out later.

From the dies the. paper passes between the guides 52 over the rollers '53. These rollers are supported by brackets 54 for vertical adjustment. These brackets are supported by the screws 55 engaging slots 56- see Fig.- 11, Sheet 2 and Fig. XVI, Sheet 9. The length of the body forming strip may be varied by the adjustment of these rollers 53.

From these guide rollers 53 the paper passes under the guide roller 57 over the plate 58 which for convenience I designate as the clutch plate as it supports the paper as it is gripped by the clutch or holding member 59-see Fig. XXI, Sheet 10.

From the plate 58 the paper passes to the feed plate60 from which it passes to a mandrel 61. The mandrels are brought successively to position to receive the paper. The blanks are' completely severed from the main strip by the temporary stopping of the strip by means of the gripper 59 while the blank is being drawn forward which tears the paper at 33;

The paper is fed to the mandrels 61 by the feed rolls 62 and 63'see Fig. XXI,

Sheet 10. The feed roll 62 is an idler and. is disposed so that the bite of the rolls is in the horizontal plane of the plate 60. .The upper feed roll 63 is driven from the shaft 64 by a train of' gears 65. The opposite end of the shaft 64 is connected to theshaft 194 by a train of gears.65'see Fig. III. The driving connections for the shaft 194 will be described later.

The feed roll 63. and the driving gears The openings 32 in the paper are positioned so that they are brought into register :with the holes 69 in the plate 60 as the paper is'advanced. The strip of paper acts as a valve closing these holes 69 until the holes 32 are brought into register therewith when air is admitted to break the vacuum by which the gripper 59 is controlled or actuated, thereby severing the blanks at 33 as stated.

Theo-perating means for the gripper 59 comprlses the cylinder 70 having a plunger 71 therein, the plunger rod 72 of which is connected by the arm 73 to'. the rock shaft 74 on which the gripper 59 is mounted. The cylinder 70 is connected by the pipe 75 to a suitable suction or vacuum means.

A conduit 76 provided with a valve 77 connects the ports or openings 69 with this suction or vacuum pipe. The valve 77 is connected by the link 78 to an actuating lever 79 pivoted at 80 on-the bracket 81 mounted on the frame-see Fig. XXI, Sheet 10 and Fig. XIII Sheet 11.

This actuating lever 79 is actuated by a cam 82 on the shaft 83 and also actuates parts of the bottom feed mechanism. The driving connections for the shaft 83 will be hereinafter described. A spring 73' is attached to the arm 73 to return theplunger 71 to its outer position.

The winding orforming mandrels 61 are mounted upon the turret 84, there being, as stated, in the structure illustrated a set of mandrels on both sides of the turret. The turret is driven with a step by step movement to advance the mandrels successively.

toposition to receive the body blanks or strips of paper as has been described.

The turret and other parts are driven thereof when stopped, I provide a brake means consisting of the brake band 93 mounted at 94 on the bracket 95-see Fig. III, Sheet 3--the free ends of the band being connected to the lever 96 pivoted at 97 on the hanger 98see Figs. VII and,

XXVI, Sheet 5, the ends of the brake band being connected at opposite sides of the pivot.

This lever'96 is actuated by the cam 99, on the shaft 100 of the Geneva ear 88-.see Fig. IVII and Fig. XXVI, heet 5. A coiled spring 101 holds the lever-to the cam.

The spindles 102 of the mandrels 61 are supported in suitable bearings on the turret 84 and are provided with pinions 103 meshing with the gear 104 on the shaft 105 on which the turret 84 is rotatably mounted, see Figs, XXX to XXXIV, Sheet 13. The shaft 105 is provided witha gear 106 meshing with a gear 107 on the shaft 83.

The gear 107 is driven from the gear 108 on the shaft 100 which is driven from the driving pulley as has been described-sec Fig. VII, Sheet 5.

WVith this arrangement, the mandrels are continuously driven, the speed of the mandrels, however, being slackened during the advancingo-f the turret owing to the planetary relation of the spindle driving gears to the turret. This is of advantage in that the ends of the freshly wound blanks or body strips are not thrown off by the rapid rotation of the mandrels. P

The mandrels are adapted to be expanded and retracted during the container forming and removing operations and tobe subjected to a vacuum during part of the con-- tainer forming operation and to a position pressure during the removing operation. In general the structure shown-see details of Figs. XXX to XXXIV, Sheet 13- is substantially that shown in my Letters Patent No. 1,342,575 issued June 8, 1920, and consists of the spindle102 and a sleeve 109 mounted upon the spindle. A hinge block or fixed segment like body 110 is mountedupon the sleeve 109 by means of the screws 111.

A pair of segmental wings 112 are piV- oted to the fixed segment 110 at 113. The wing segments 112 are operated to expand and retract the mandrel by means of the wedge segment 114. This wedge segment is mounted for radial movement in the sleeve portion "109 and is actuated from'the slide ar 115 slidable in the way 116 out longitudinally in the spindle. The slide bar is connected to the Wedge member 114 by means of the links 117. f 1

With this arrangement as the slide is reciprocated the wedge member 114 is projected orretracted to expand or retract the wings 112. Springs 118 are provided to hold the wing members 112 normally in their collapsed position.

The'mandrels are expanded and retracted when in their proper positions bymeans of the fixed cam 119 which acts upon the lever 120 pivoted at 121 on theturret and forked provided for facilitating accurate adjust-v ment. A spring 127 holds the roller 128 of the lever against the cam 119.

. The fixed body portion 110 of the mandrel is provided with air openings 129 preferably disposed in a triangular relation as shown in Fig. XXXIV, Sheet 13, corresponding to the tapered front end of the body blanks or strips so that when the front end of a strip is projected over these holes by the feed means described, the suction draws and holds the end of the strip upon the mandrel.

The openings 129 communicate with the passage 130 in the mandrel spindles 102- see Fig. XXII, Sheet 13. The spindles are providedwith disks 131 having radial passages 132 therein and a peripheral passage 133 registering with thevpassage 134 in the heads 135 of the radially disposed conduits 136-see Figs. XXIX and XXIX, Sheet 12.

The conduits 136 are disposed radially within the turret and are connected to'a sleeve-like hub 137-see details of Figs. XXVII and XXVIII, Sheet 8, the shaft 105 being tubular-see also Fig. III, Sheet 3to receive the pipes 138 and 139, the pipe138 being the vacuum pipe and 139 the pressure pipe. The hub member 137 is mounted upon an annular valve member 140 having ports 141 and 142 therein registering with the pipes 138 and 139 respectively and with which the conduits 136 are'brought into. register as the turret revolves. The conduits being. connected to the suction pipe 38 when the mandrels are in receiving position and are cut off there-from as the mandrels are like head 146 on the swinging feed arm 147.

The arm 147 is mounted on the rock shaft 148 and-connected by the link 149 to an arm 150 on the rock shaft 151 which is provided with an arm 152 actuated by the cam 153 on the shaft 83-see figures last referred to.

The shaft 148 is tubular, and the arm 147 is provided with an air passage 154 indicated by the dotted lines in Fig. IX, Sheet 7, the purpose being to provide a suction or vacuum for holding the bottoms to the feed lead 146 during its stroke. This shaft 148 is connected by the pipe 155see Fig. I, Sheet 1to a suitable vacuum producing means. The air is controlled by a valve designated generally by the numeral 156see Fig. Iwhich is actuated by the swinging of the arm. The details of this valve are not illustrated as it is deemed suflicient to state that the valve is such that the passage is connected with a vacuum producing means during the swinging movement of the shifter plate 146.

. The bottoms are discharged from the bottom of the stack in the hopper one by one to the feeder 146. The hopper discharge mechanism consisting of the swinging discharge member 157 pivoted at 158see Fig. XIII, Sheet 8. This discharge member is provided with a segment 1'59 coacting with the rack 160. This rack is provided with a slide portion 161 mounted in supports 162 and connected by the'link 163 to the lever 7 9see Fig. XIII, Sheet 8, and Fig. XIII Sheet 11. i

Positioning stops 170 are provided to position the bottoms above the feed lead 146.

The operation of these feed members is prior to the winding of the body strip thereon so that the body is wound upon the bottoms.

The ends of the mandrelshave openings 171 therein communicating with the passage 130 so that the bottoms are subject to the vacuum to hold them in position and to pressure for ejecting the cartons-see Flg. XXII, Sheet 13-.

I will now describe the adhesive applying means which are arranged so that the adhesive is applied to the body blank or strip as it is wound upon the mandrel in forming the container body. The details of this ad hesive ap lying means are shown in Figs. XIV and V, Sheet 11. It comprises an ad hesive tank 172 arranged so that the mandrels are above it when they are in their body forming position. The adhesive is kept at the desired level in the tank 172 by means of the feed pipe 173 and the overflow pipe 174, the supply tank being shown at 175.

The adhesive applying roller 17 6 and its coacting adhesive feed roller 177 are mounted in a rocking frame 178 supported on the shaft 179 so that by rocking the frame the applying roller 176 is brought into and out of coacting' relation with the mandrel or the body blank as indicated by dotted lines in Fig. XV, Sheet 11.

The rollers 17 6 and 177 are provided with meshingv gears 180 connected by the gears 181 to the shaft 182 on which the frame 178 is mounted. This shaft is, provided with a sprocket wheel 183 connected by a sprocket chain 184 to a sprocket 185. 185 is connected by the shaft 186 and beveled gears 187 and 188 to a shaft 190. The shaft 190 is connected by the beveled gears 191 to a shaft 192 disposed cent-rally of the ma- The sprocket chine which shaft is connected by the beveled gears 193 to a shaft 194 extending across the machine from side to side. This shaft 194 is connected b the beveled gears 195-see Figs. I and I Sheets 1 and 2-to a shaft 196 having a beveled pinion 197 on its lower end meshing with a gear 198 on the face of the gear 1.08. The details are of importance mainly in showing a driving connection whereby the several operations are properly synchronized or timed.

The adhesive roller frame 178 is actuated to bring the applying roller 176 into and out of operative position by means of the arm 199 connected by the link 200 to an arm 201 "on the rock'shaft 202. This rock shaft has as an arm 203-see Fig. IIIto which the link or connecting rod 204 is connected, the other end of this connecting rod being slidably supported and provided with a roller 205 coacting with a-cam 206 on the cam shaft 46. A spring 207 connected to an arm 208 on the rock shaft 202 holds. the roller 205 against the cam.

With the parts thus arranged the adhesive applying roller is brought into operative position at the proper time to apply adhesive to the strip as it is rolled upon the mandrel and is shifted to inoperative position so that no adhesive is applied to the mandrels themselves. The rock shaft 202 is provided with a lever 202 by means'of which it may be actuated manually to hold the adhesive applying roller in operative position. A latch 202" mounted on an arm 202" on the rock shaft is provided for holdin the rock shaft in operative position. This Iatch'is adap ed to rest on the frame'as shown in Figs. I and II, or to be swung out of operative position when desired. 7

As the strip is wound upon the mandrels, it is engaged by the pressure or forming roller 209 and the several convolute windings are pressed together asthey are wound upon eral windings are firmly pressed together and are-drawn tightly one upon the other,"

the adhesive is not squeezed out.

The pressure roller is mounted to swing to and from operative relation to the mandrels as they are successively brought to forming position, the roller being, carried by a frame 210 pivoted on the shaft 194, the frame being provided with an arm 212 carrying the roller 213 coacting with a cam 215 on the cam shaft 46see .Fig. XXI, Sheet 10. The shaft 216 of the pressure roller 209 is connected by the beveled gears 217 toa shaft218 which in turn is connected by the beveled gears 219 to the shaft 194 on.which the frame 210 is pivoted. The adhesive applying roller preferably remains in operaative position so as to apply a complete coating of the adhesive to the outside of the body, an adhesive being used which will provide a glass like finish. When this is done I provide a wiper 219 positioned at the second slip of the turret-see Fig. XXI, Sheet 10. This wiper is supplied with a suitable solvent so that the adhesive is spread and smoothed to provide the finish.

As the formed containers are carried by the mandrels from this position, they are brought into the range of a drying blast of heated air from the blower nozzle 220-see Fig. II, Sheet 2, and Fig. XXI Sheet 12. This is of advantage in that it hastens or speeds the setting of the adhesive thus enabling the machine being speeded up. The air heating chamber is shown conventionally at 221 and the blower at 222-see Fig. II, Sheet 2, and Fig. IV, Sheet 4.

As stated, the body is wound upon the bottom and it is wound so that the end of the body projects beyond the bottom as shown in XXXV, Sheet 10, and F ig.

XXXVI, Sheet 12. During one of the periods of rest of the turret, the second period after the body is formed in the structure illustrated, the adhesive is applied to the bottom and to the portion: of the body projecting beyond the bottom. This adhesive is applied by an atomizing of blast Ineanssee Figs. XXXV, Sheet 10, and XXXVI, Sheet 12,comprising an air nozzle 223 connected by the pipe 224 to a valve 225 connected to a source of supply of air under pressure by the pipe 226. The adhesive supply pipe 227 is provided with a valve 228 controlling its nozzle 229. The air nozzle 223 and the adhesive nozzle 229 are arranged so that as-the air blows across the adhesive nozzle, the adhesive is atomized or sprayed onto the work. These nozzles are mounted on a slide 230 so that they may beadjusted to and from the work as the" turret is advanced. The slide 230 is actuated by a link 231 connected to an arm 232 on the valve stem 233 of the, valve'225..

See Fig. XXXVII, Sheet 10. The valve 233 is provided with a port 235 adapted to be brought into register with the port 236 in the supply pipe 226 upon which the valve is rotatably mounted The valve stem or rock shaft 233 is operated from a plunger rod or link 237 having the roller 238 traveling on a cam 239 on the shaft 83. A spring 240 is connected to the bracket 241 on the frame'and to the link or plunger rod 237.

The valve 228 is actuated by the plunger rod 242 from the cam 242. With this arrangement theair and adhesive are controlled so that when the mandrels are in proper position, the adhesive is sprayed-onto the bottom and the projecting portion of the body so that when the body is crimped or turned upon the bottom at a later stage it is retained by the adhesive. This takes place at alater step and the mechanism by which it is accomplished is detailed in Figs.

XXX viii, XXXIX and XL, Sheet 6. It

comprises the spinner head 243 mounted on the shaft 244, the shaft being connected by the belt 245 and suitable pulleys to the driving shaft 246 which in turn is provided with a pulley 247 driven from a belt 248 from a line shaft or other source of power.

The spinner head 243 is conformed to embrace the body and has a curved portion 249 adapted to turn the body retaining flange 250 upon the bottom as shown in Fig. XL,

Sheet 6. The shaft 244 besides being rotatably mounted is mounted for axial movement so that the spinner head is pushed upon the container as it is rotated.- This is accomplished by providing the shaft with a pair of collars 251 between which is a shifter member 252.

The shifter member 252 is actuated by a toggle consisting of pairs of links 253 and 254, the links 253 being connected to the shifter member 252 while the links 254 are connected to the bearing 255 at the outer end of the shaft. The yoke 256 is connected to a lever 257 urged in one direction by the spring 258 which is connected by the link 259 to a lever 260 pivoted at 261 on the frame and provided with a roller 262 coacting with the cam 263 on the shaft 83-'see Figs. XXXVII and XXXIX, Sheet 6, Fig.

I, Sheet 1, and "F ig. II, Sheet 2. a When the mandrel is in its bottom securing position as shown in Figs. XXXIX and -XL, Sheet 6, and prior to the completion of the spinning up from the bottom, the body is internally beaded at 263 just above the bottom, preventing the bottom being shoved up into the body, the bottom being held on the inner side by this internal bead and on the outer side by" the flange turned
