The .main drive Motor l is connected for continuously operating shaft 2 having pulley 3 connecting drive belt a extending to pulley 5 on shaft 6 (Figs. 1, 2). This shaft 6 has xed therewith pinion 7 in mesh with gear 8 thereby providing continuous rotation for this gear 8. By treedie 2 having dried fulcrum l() on base 11 for housing 12, there may be through depressing treadle 2 a pulling down of rod 13 (Fig. d) Vagainst resistance of' spring le as coasting with collar 15. This roel 113 in auch downward movement is directed by bracket ld carried by the housing 12. This downward pull of the rod 13 and its head 17 to beclear of way 16 thereby permits spring 18 to thrust plunger 2o axially into the seat vacated by the head 12 to connect this gear 8 to companion clutch niember or collar 21 fast on shaft 22. There is thus provided one complete rotation for the shaft 22 at each depression of the treadle or lever il.

This shaft 22 extends through 4the housing 12 and at its remote end carries sprocket wheel 23 (Fig. 3) from which extends sprocket chain 24 as a speed reduction to sprocket wheel 25 fast with shaft 26 in the housingr 12 to give herein a four-to-one speed reduction ratel of rotation for the shaft 26. it accordingly follows that at each depression of the treadle 2, there may be a 88' travel of the shaft 26.

Blank set-up and end sealing collapsed blank 27, (Fig. 32), as a dat article received in compact form by the dairyinan, is opened up into'rectangular tube (Fig. 33) by the attendant at this end sealer machine. This attendant disposes this set up tubular blank 2'? to slide upon block 28 (Figs. 1, 5), with the attendant standing at operators station adjacent the treadle 9. This thrusting oi' the tubular blank on the block 28 is with the blank extension 28 down over the tube and the block end in position to have, as to the attendant, the position shown in Fig. 34. The attendant with this blank thrust down on the block 28, collapses similar opposing minor end flaps 30 toward each other over the block 28, thus disposing such in proximity to the end of the block 28. The attendant in thus directing these minor flaps 30 has such in that proximity to the block 28, that there is freedom to ride under non-rotary bar 31 mounted in brackets 32 on the housing 12. Y

Adhesive applying deoice Fixed to rotate with the gear 8 loose on the shaft 22 is sprocket wheel 33 (Figs. 2, 4) continuously -rotatable and connected by sprocket chain 34 with sprocket 35, fixed with gear 36 and loosely mounted on the rod or bar 31. This gear 36 is in mesh with pinion 37 (Figs. 1, 5, 6) fast o n shaft 38 carried by the brackets 32 to pivot on the rod 31. These brackets 32 are connected by plate 39 carrying pockets or glue pots 40 adjustable by screws 41 (Fig. 7) to vary their clearance as to adhesive or glue applying rolls 42 fast on the shaft 38. These rolls 42 are accordingly closures for the respective glue pots and, as rotating relatively thereto on their surface, carry a thin coat of adhesive. i

Shaft 26, as extending into the housing 12, carries fast therewith ange 43 (Fig. 5) connected by bolts 44 with ilange 45 fixed with sleeve 46 rotat'ably mounted on stub shaft 47 held by set screw 48 in'bracket '49 fixed with the' frame or' housing 12. It is thus seen that shaft 47 is nonrotary and provides a bearing for the sleeve 46. This sleeve 46, adjacent the bracket 49, carries collar 50 held by set screw 51 against rotation relatively to the sleeve 46. This collar 50 is accordingly angularly adjustable relatively to the .sleeve 46 and has fast therewith cam disk 52 having seats 53 (Fig. 2). Roller 54 rides on this disk 52 and is carried by extension 55 from a bracket 32. The extension 55 is of such length that normally the shaft 38 is positioned as the roller 54 is on the cam 52 to hold the rolls w clear of operative position. However, as the roller 54 rides into cam depression 53, the glue carrying rolls ti2 then swing radially, inward and are in operative position.

With the bloclr 22 approaching upper position, the operator may charge a tubular blank 27 on. the bloei; 28 with the minor flaps 38 directed over the end of the block 28. From this charging tion there is travel of the carried block 28 ninety degrees (96) for this block 28 is directed by arm. 56 connected (Figs. 5, 10) by bolts 5'? to theilangeo 43, e5. 1n this travel, wings 53 spread major dans 59, from radially extending position as to the shaft 23 and from parallel relation (Fig. 35i to spread relation (Fig. 36), against raised portions to (Figs. 5, 12,14) on members 61 having bearings or tubular openings 62 mounted on tubes 83 anchored by nuts 6a in spiders 65, 66. The

spider 65 is connected by bolts 67 with the sleeve ed (Fig. 5). The spider 66 is connected by set screw 88 with the shaft 26. It thus follows that these raised pads 6b travel angularly with the shaft 26, and the block 28 and in thistravel, at the position where the disk cam 52 has depression 53 register with roller 54, the glue rolls 42, by gravity, swing radially inward upon. rod 31, as an axis, to contact the flaps 59` on the radially outward side and thus coat such dem with the adhesive, due to the relative rotation of these rolls 42 as to the flaps 36.

Folding The block 28 is provided with stem 69 guided in tubular arm 56 (Fig. 5) and engaged by compression spring 70, the compression of which is determined by plunger 71 as acted upon by stationary cam 72 carried bythe non-rotary shaft 47. This stem 69 has fixed thereon collar 73 against which engages compression spring 74 in open-work region of the arm 56 abuts outer terminus 75 of open-work region in the arm 56, This spring 74 is stronger than the spring 70 and accordingly normally retains the block 28 retracted against the action of the cam 72, but on the operation of the cam 72 for outward thrust, there is such compression of the spring 70 as will locate this block in the desired radial position at the charging stage approximately ilush with the pads 66. i

In the travel from this charging position, clockwise, (Fig. 11) cam 72 has portion 76 hold the block 28 in this flush position until after the gluing means or rollers 42 have acted, then depression 77 in the cam 72 allows the head or block 28 to be retracted by the spring 74 radially inward.

This deects slightly outwardly both of the flaps to the block 28, for the member 61 carries pin 81 extending through slot 82 in the tube 63 (Fig. 14) there to be engaged by compression spring 83 normally thrusting a roller 78 or 79 against the cam 80 effective in its cooperation with said roller, to shift the member 61.

At the gluing stage, before the head 28 has withdrawn inward, cam portions 84 coact with rollers 78. 79, bringing the members 61 into proxunity to the mank tube on the mock 2s. .Past the' gluing operation, there is relee from this held position by cam portions 85, 86. 'I'he roller 78 from cam portion 85 travels on cam portion 87 toward and under a partially raised flap 59, thus effecting folding of such flap 59 over the pair of iiaps 30 (Fig. 9). As this operation is completed, cam portion 88 retracts this folder element or support 61 and cam portion 89 eoacts with roller 79 for thrusting companion member 61 toward the depressed block 28 to fold the second ap 59 over the. rst ilap 59 in thus completing the end closing sealing operation. 1

This roller 79 in coasting with cam portion 89, holds this second, and accordingly both of the naps 59 in the sealing position for converting this open end tubular blank into a one-end` sealed container.

At the peak position for the cam 87 in efecting folding of the first flap 59, .the roller 78 as loeating the support 61 in this folding position, is over the block 28, and cam portion 90 (Fig. 11) of the cam 72 thrusts this block 28 radially outward into compacting position, in supplementing the sealing action of the sllpPOl' 61 on the rst nap 59. Thereafter, cam portion 91 allows the block 28 to be depressed slightly during the period that the cam portion 88 is eective. At the region for the cam portion 89, this cam 72 has cam portion 92 as a holding means for snugly compacting the pair of major naps 59 against the folded minor naps 30 in the holding sealed during the travel back toward charging position, where this cam portion 92 terminates in cam portion 93 in releasing the block 28.

Eiector In the charging of the tubular blank on the block 28, the inward distance of the blank as to its extension 94 (Fig. 36) abut stop 95 (Figs. 8, 10, 13). This stop 95 is a set screw adjusted ledge carried by cross head 96 extending into slots 97 of the spiders 65, 66. This cross head 96 extending into slots 97 of the spiders 65, 66, terminally carries rollers 98, which, in the region from cam portion 93, along cam portion 99 (Fig. 11) of the cam 72, coact with guide 100, 101, (Figs. 10, 13) fixed with the housing 12, thus moving this ledge radially outward along the block 28 and thrusting the one end sealed container outward, radially oif the block 28, so that the operator may readily remove upwardly such completed container and supply in its stead a tube blank for a repetition of this cycle of operations in the four stages of this intermittent drive as herein, such stages being from the upper charging 90 clockwise (Fig. 10) to the first nap sealing as a rst stage; directly in passing therefrom there is the second major ap sealing as the second stage; and-third and fourth stages as the holding for allowing the glue or sealing means to set.

Coating mechanism The operator in taking the one-end-completed blank from the gluing mechanism, deposits such from the operators station near the treadle 9 in rectangular tubular pocket 102, open ended above and below. These pockets 102 are carried by endless belt 103 (Fig. 1). Each of these pockets 102 (rms. 1, 151s) im timer iufm-mds se ated by 4torsion spring 105 to limit the descent of one-end-cled blank 106thereinto. This endless conveyor 103 is shown as having a drying or hardening section for the glued or just-formed container as a time interval. This conveyor 103, as actuated in synchronism with the end gluing mechanism for shaft 26, is connected by coupling 107 with shaft 108 upon which is mounted bevel pinion 109 in mesh with bevel pinion 110 on vertical shaft 111 carrying spur g'ear 112 in mesh with intermediate gear 113 coacting with gear 114 fixed with roller 115 mounted on fixed' vertical shaft 116. This roller 115 is thev live roller for the conveyor 103, which conveyor 103, from the roller 115, passes about idler roller 111i7 on vertical Shaft 118.

This conveyor as conducting the containers 109 from about the roller 117 (Fig. 1) for a glue hardening or seasoning operation, brings these con..- tainers step by step to chute 119l1aving cam edge 120 coacting with the depending trigger 100 (in travel to the left, Fig 15) to shift such clear of closure position for the botom o1 the pocket 102 as coming into position at the chute 119. The container 106, thus drops closed end downward through the chute 119 (Fig. 17) into open wort: pocket 121 (Fig. 17) carried by arm 122 fast on the shaft 108. This device rotates step by step counter-clockwise in housing 123 having therebelow leakproofcoating bath chamber 12a herein shown as charged with molten paramn 125, the molten condition of which is maintained by hot water jacket 126 disposed in base 127 as carrying the housing 123. The arms 122, besides carrying the open work pockets 121, which pockets 121 have closed ends 128, areprovided with arms 129 having opposite extensions 130. These arms, laterally of the pockets 121, coact, from positioning the pocket adjacent the chute 119 as held by a pin 131, to partially tilting the pocket 121, as containing a container 106 in passing from each position.

Full orienting of the pocket is prevented by pin 132, so that, as the counter-clockwise movementl of the arm 122 continues, the pocket.12l is directed, with its closed end 128 upward, into the i therein loaded with a quantity of the paramn, 1

upward out of the bath. In this ascent, pin 13e engages the rod 130 and tilts the pocket 121 to orient the open end of the container downward for slopping out of the container` the scooped-up charge of the molten paraffin, for flowing back into the bath 124. 1n this ascent, through the open work closed end 128 of the pocket 121, spring is eifective yieldably for urging this parailln dipped or leak-proof-coated container 136 out of the pocket 121 upon chute 137 (Figs. 18, 19, 20, 21). Hot water circulation pipes 138, through bearings 139 and return bend 140 adjacent the chute 137 maintain a softening temperature for the leak-proofing substance, so that the coated container 136 asv striking the chute 137, 140, freely slides down such incline, to be deposited upon conveyor 141.

`ing has adhesive tendency and in order to avoid ilo 149 es the live or driving pulley for conveyor 141.

This conveyor ldLremote from the pulley 14:9, passes about pulley 150 corried by bracket 151 on the conveyor freine. This conveyor is soxzord-s ingly given a step hy step rotation in synchrowith the gluing mechanism as well as the costing mechenism.

Fast with the shsft 148 is gear wheel 152 in mesh with pinion 154i on sheft 155. This t 155 entends (Fig. 1) past the conveyor 1111 transversely and there carries arm 156 from which entends link 157 (Figs. 1, `21) to lever 158 having fixed fulcruxn 159. From this lever 158 extends link i to pin 161 es directed hy centrally countersunk rhomboidol com 162. From this pin 161 is spring extension 163 inwardly extending from beyond the link 160, duplicnte of which mechanism is on opposite sides of this upper reach of the conveyor 141.

1n the step by step rotation of the shaft 155, the pins 161 ride olong the outer sides of cams 162. These-pins then approach each other as directed by the inclined sides of the cam 162 towerd the shsft 1:18 (Fig. 1) end cause the yield= able arms 188 (Fig. Ii0) to engage the coated container 136 slightly above its center of grevity, ond thus in the cycle of rotation of `this shaft 155 with the pins 161 traveling swoy from the shaft 1de along the inner portions of cams 162 and directed by spring ngers 16d, grip this container 188 for hauling it oil the coating machine end wiping the bottom of such container across scraper wire 165 (Figs. 19, 20, 40).

it the cycle of the single complete operation of the rotation of the shaft 155 in its four-to-one speed-up relatively to the sheft 108, the pins 161 come to diverging portions of the cams 162 sind are clear of the springs 18d, thus causing the pins 161 to move outwardly from the conveyor 141, with the yieldable arms of springs 163 releasing the set-up costed container 136 on the conveyor belt 1111. This conveyor belt is o o length to the pulley 150 sumcient to allow the paraffin coating material to congeal. This conveyor lil in its return reach on the under side is contacted by wire scraper 166, adjacent hot water line 167 for removing any excess of the coating material so that such may be deposited in vessel 168 therebelow Thus the conveyor belt 141 is maintained clear of coating accumulation, so that the articles may not freeze thereto or be tilted in the shifting of the articles thereolong. The articles accordingly as traveling along the conveyor 141 come to chute 169- and there accumulate in receptacle 170 (Fig. 1). Charging and final closing From drive shaft 2, pulley 171 is connected by belt 172 to pulley 173 having speed reduction gearing connection 174 to gear 175 as continuously rotating and mounted on shaft 176 (Figs. 1, 22). At the second operators station, treadle 177 may be depressed to operate rod 178 and thus release clutch 179 similar to the clutclr at the gear 8. This permits the gear175 to operate the shaft 176 one complete rotation.

Bottle extension closure partial collapse Mounted on this shaft 176 is cam 180 (Figs. 22, 3l). cem coects with pair of spaced bers 181 as directed by guide 182 carried by cross bor 183 oi frame 18e, for descent against lthe, resistance of tension springs 195 carried from overhead her 188 mounted by the frame 184. These here 121 extend post the guide 182. Extensions 157, 188, ere fixed guides for guide rod 187' fired with cross-head 189, 190 (Figs. 26, 27, 28). These hors 181 extend respectively to links 191 connected to arms 192 of levers having iulcre`1o3 and extensions 19d therebelow. The cross-heed 199 lies, in opposing relation pivotal mountings 195 ond upwardly extending V- tongues 19d (Fig. 29) engaged by the inwardly disposed free ends oi' thev erms 194 of ongle levers 192, 19t. These pivotally mounted, upwerdly extending. il-tongues 196 have depending lorwled lower portions 197 tending normally to hold these tongues 196 in slightly diverging upward position from the pivotal mountings 195.

The operator et the station of the treadle 177 moy remove container 136 from the receiver 170 and place such on platform 198 (Figs. 1, 22) in position below the cross head 190 and abutting nger 199 on rod 200. The depression of the pedal or treadle 177 thus starting the shaft 176 for e. full rotstion, lowers this cross-head 190 into position to bring the tongues 196 in opposing relation adjacent opposite extension portions 201. Furthermore, rotation of' this shaft 176 brings cam portion 202 to coect with intermedlate rod 293, thus shifting such rod relatively to the hars 191 between which bers 181 the rod 203 is guided, so that there is e, rocking of the angle levers 192, 19d, to swing `the tongues 196 toward each other and thus re-establish the crease lines for folding in the end closure extensions, which lines have been given rigidity by the coating operation. The container entering element is indicated at 208', being secured to the lower end of rod 203, and this element cooperates with the v-tongues 19d in re-establishing the crease lines hy interiorly supporting the container wells. This ineens there is thus initiated a partial collapse extension 204 of the container 138.

The completion of the shaft rotation after this initiating of the extension collapse results in so disposing the cams 180, 202, that the shorter radius portion is downward and the springs 185 may eect recovery or ascent of the breaker device clear of the container 136 so that the attendent may grasp handle 205 and slide the rod 200 in bearings 206 to the right, thus shifting the ex tension re-established fold line container 136 clear from its position under the breaker to e. second position along the platform 198. As so disposed, the shaft 200 may be rocked to clear the nger 199 from the line of the platform 198 end the rod 200 shifted to the left to the initial position.

Filler The shaft 176 is shown as equipped with cam 207 (Figs. 22, 23) coacting with rod 208 as directed by guide 209. This rod 208 carries xed collar 210 against which acts spring 211 for urging cylinder 212 downward in reservoir 213 about tubular discharge tube 214. This cylinder 212 is equipped at its lower region with check valve 215 freely opening for flow of milk into the cylinder 214 and closing against outflow. A measured volume of milk is thus charged into the res- I nomma ervoir container 213 by way of pipe 214 for manitaining a level of such liquid therein. The ascent of this cylinder 212 lifts the measured quantity of liquid in the cylinder 212 and allows such to descend to be refllled with its major quantity of liquid in this filler for second charging operation.

The handle 205 is again given the single cycle of operation for shifting the charged container 136 from the lling station by the action of finger 216 similar to the finger' 199.

Coating melting ,for final scalino The shaft 176 carries cam 217 (Figs. 22, 24) effective to depress rod 213 as directed by guide 219. This rod 218 has xed thereon collar 220 with which coacts compression spring 221 normally holding this rod 213 elevated against the cam 217. This rod 218 in its lower region carries jacketed electric resistance energized by electric current connection thereto (not shown). 'li'his resistance provides heating element 222 as a warmer for softening the adhesive as coating the extension 4204i of the container 136. This softening or partial melting of the parailln coating on the container 136 brings about a condition so that the operator after this heater 222 has ascended, may again operate this rod 200 through the handle 205 for causing` finger 223, similar to the `finger 199, to shift from third station to fourth station on the `platform. 198. At this position vthere may be ilnal closing operation mechanically or,as herein disclosed, by the operator, and the operators action at this station is shown as in order. The extensions are thus brought into fully collapsed and primary sealing position (Fig. 42) with the softened paran creating adhesive condition so that vthe full closure'of the vessel is thus attained. From this fourth station the closed con'tainer may be abutted by finger 224 on the shaft 200 for shifting to a fifth station,or additional station. 4

A Final sealing closure The shaft 176 is provided with cam 225, herein shown as of general eccentric form (Figs. 22, 23). Coacting with this cam 225 is roller 226 on lever 227 having hired fulcrum 228. Depending arm of this lever 227 has rod 229 pivoted therefrom surrounded by compression spring 230 tending normally to tilt this lever to hold the roller 22d against the cam 225. This rod 229, as directed by the frame 184 through which it extends, terminates in toggle 231, upper link of which is mounted in bracket 232 carried by the frame 184. The lower link of this toggle is confinedv by bracket 233 with lever extension 234 therefrom in oppostion to abutment 235 carried by the frame 184.

This abutment 235 and extension 234 forma pair of opposing jaws which receive therebetween upwardly extending rib 236 of the collapsed extension or upper end closure for the bottle 136.

Accordingly, in the rotation of the cam 225, the

lever 227 is rocked against the resistance of spring 230 for effecting through the toggle 231 shifting of the movable jaw 234 toward the abutment 235 for squeezing the rib or tongue 236 therebetween in a final clamp holding. One of these Jaws, herein shown as the movable jaw 234, is provided with stitcher device or stapling machine for taking wire from spool 237 and by means of plunger 238 operated from mechanism movable relatively to the Jaw 234, eect stapling operation through the extensloni236` in forming stitch 239 (Fig. 43). I

This stapling orl wire stitching device may be of a general form, say as shown in Patent 1,1l3,879,

Craig, Oct. 13, 1914.

' l Uperation It is accordingly seen that hereunder there may be effected from the receiving of knockdown containers, the' preparation of such containers for sealing and sealing into the contain-h vers of a'. substance herein shown as fresh to be supplied to the intimate consumer.

treadle 9 for opening up the flat blank 27' into tubular form and thrusting such blanlr down upon the block 28, there to have end aps 59 glued and sealed thereagainst. Such container 106 is removed from the block 22 as another tube is charged thereon. The removed container is placed in pocket 102 of conveyor 103 conducted for a drying period and then automatically discharged into the coating machine, there to have par dipping, then conveyed by conveyor 141 into proximity to the station of the second operm ator, where the article may be in the maintained synchronism of the machines against excessive accumulation.

This operator may locate the completed milk bottle container in position for breaking of the coating rigidity to reestablish the initial creasing or end closure collapsing condition. The procession or sequence of these containers in these step by step operations brings this collapsed extension container into position for charging; then to have adhesive condition producing melting down of the coating; primary sealing of the ilnal end closure; then full or complete sealing; and even stitching, if such be desired, with the article as thus completely sealed and in the container shifted further along the platform 198 for deposit in cartons or other means of delivering to the place of storage or transit.
