Fig. 23 is a plan View of the packageafter the Wrapper has beencrimped and sealed;

Fig. 24 is a section online 24T-24 of Fig. 23. In Wrapping many articles it is desirable to seal the articles in a package which is airtight in Vorder to properly preserve the Wrapped article. WaXed or parafline paper is commonly used for providing an air-tight wrapping but in order to make the wrapping really tight itis necessary that there shallbe no. unsealed folds aording passage tothe interior of the wrapper.

In the present 'invention the wrapper is folded jbout the article with the edges overlapping on three sides of the article and extending face to face and the overlapping edges are then sealed together by the application ,of heat which partially melts the paraiiine and the melted paraiine is then chilled to completely seal the contacting faces of the wrapper. The Wrapper thus sealed-is illustrated in Figs. 23 and 24 ofthe drawings. i

l The projecting edges are then 'folded against A'the portion of the package containing the wrapped article. By sealing the edges of the wrapper while they project away'from'the karticle it is possible to effect the seal with-A portion out subjecting the article to the heat of thev sealing irons.v It is also possible to insu-e'4 uniform pressure against the portions of the wrapper to be sealed which cannot be done where it is attempted to seal the flaps against -the sides of the wrapped article. By way of illustration a machine is shown in the draw? 11m i ings for wrapping candy chewing gum briquettes, but it will be understood that the invention is not conned to a machine `for wrapping particular articles, but may be applied to wrapping a large variety of commodities.

In the drawings,the numeral designates the base or supporting frame for a wrapping machine having a driving pulley 31 which may be driven from any suitable source of power. The pulley 31 is connected by a belt \32 to a pulley 33 on a shaft 34 and the gearing 35 connects the shaft 34 with the main drive shaft 36. The drive shaft 36 may be provided with a handle 37 by means of which the machine can be operated by hand for inspection or other purposes, when desired.

At the top of the frame 30 is a hopper 38 in which the briquettes to be wrapped are placed. Suitable feed rollers and agitating mechanismV are provided at the base of the hopper 38 driven by a belt 39 extending upwardly from the shaft 34. The briquettes are directed from the hopper 3 8 into downwardly extending guideways 40 and 41 in which the 'edges of the briqucttes travel in grooves in guide bars 42, 43 and-44, as illustrated more clearly in Fig. 3. Positioned below the lower ends of the guideways 40 and 41 is an assembling wheel 45 having disc portions 46 and 47 differing in diameter so that the disc 46 pro-L jects radially beyond the disc 47 by anamount eqlrllllal to the length of one of the briquettes w ch are snown at 48 in Fig. 3.' The discs 46 and 47 are provided with radial grooves 49 and 50, respectively, into which the briquettes enter from the lower ends of the guideways 40 and 41. The grooves 49` and 50 extend inwardly to the same radial distance from the axis of the wheel 45, the depth of the groove in the disc 47 being equal t^ the length of one briquette, while the dept;L of the groove in the disc 46 is equal to the length of two bri- -quettes A circular groove 51 extends inwardly'from the outer lateral face of the disc 46 and a bracket 52 is mounted on the sup-v porting` frame 30 and provided with an ar- 'cuate fiange 53 which extends into the groove 51 and has its outer face Hush with the 'outer I periphery of the disc 47. It will be appar- .ent that the briquettes entering the groove 49 in the'disc 46 will be arrested by the flange 53 'so that asinV lebriquette will be admitted at one, time an will be. held by the flange 53 with,its inner. end in registration with the, briquette inthe groove 5() of Y outer end of the rIhewheel 45I intermittently rotated by 4"90 steps and between successive-rotations is brought to rest with the radial grooves in reg Iistr'a'tion with the guides 40 and 41. Each time the wheelcomesto .rest a pai-r of briquettes are deposited in the grooves registering with the guides40 and 41 and at the nextrtation the briquettes are brought to a position on a level with the axis of the assembling Vwheel and are arranged flat side down, as shown at the left in Fig. 4.v The wheel 45 may be rotated by any suitable driving mechanism, such as a lever 54 engaging a ratchet wheel 55 on the shaft 56 which supports the.

wheel 45. The lever 54 is oscillated by a rod 57 operated by a cam 58 on the main drive shaft36. The mechanism may be timed to impart a-.quarter of a rotation to the wheel- 45 for each revolution of the drive shaft 36. A receiving platform 59 is mounted on the frame 30 and has its upper surface disposed in registration with the lower `faces of the briquettcs 48 held in the slots 49 and 50 extend-v 2,'and oscillated about its pivot by a link 63y secured to an arm 64 which is pivoted at 65 on the frame 30 land provided with a cam roller 66 which engages a cam groove in a cam wheel 67 secured to the main drive shaft 36. The arm 61 is timed to oscillate during the pause in the rotation of the wheel 45 and the movement of the finger 60 brings the two briquettesinto alinement with each other and transfers them from the wheel 4 5 to the platform 59. A guide plate 68 is spaced above .the platform 59 and carries guide members 69 into which paper wrappers 70 are fed in a vertical position by any suitable paper feed mechanism, not shown. The briquettes 48 are moved forwardly on the platform 59 by the finger 60 until they pass the transverse. ning for the wrappers 70, asillu'stratedzin ig. 7. This will fold the upper and lower edges of the wrapper 70 backwardly againstthe top and bottom faces of the 'briquette's and draw alle., folded naps into-the opening between the y platform 59 and upper guide 68.. When the finger 60 is returned the briquette will be de he platform 59 is provided with and 7 2 over which the briquettes 48 aremoved posited in the opening between theplatform Vbythe iingerGO. .An arm 73 is pivoted at 74 on a horizontally extending arm 75which in turn I'is pivotally mounted at 76 'on the' frame 30and oscillated vertically by acam 77 on VVVthe shaft 36.-v The arm 73 is connected by a link 78 on the larm 64so that both vertical and horizontal movement is imparted to the arm 73. The arm 73 carries a pair of fingers 79 and 80 which are pivoted at81 on the vend'ofthe arm 73 and are spaced apart to register with the slots 71 and 72 in the plat- -form 59.- The fingers 7 9 andl 80 are resiliently held'b'ysprings 83 which tend'to rotate the top ends ofthe fin ers forwardly or to the right, as viewed in ig. 7. -The movement of the arm 73 projects the fingers 80 upwardly through the-slots 71 and 72 in the rear of the briquettes after the finger has been withdrawn, leaving the briquettes in the foremost position to which they are moved by the finger 60. Each of the fingers 79 and 80 is provided with a forwardly projecting noseiece 84 which enters between the baekwardly irected flaps of the wrapper and engages the rear edge of the briquet-te. Theiingers are then moved'forwardly and discharge the briquettes from the forward edge of the plat-` crimped at their ends bycrimpingplates 86, one at each side of the lturret 85. The crimping plates 86 are carried on'lever arms 87 which are piv'oted on a st-ud "shaft`88 pro-y jecting outwardly from the machine frame.

` rearwardly to engage thefolded edge of the vwrapper and press the folded portion backwardly between the end flaps, as indi' cated in Figs. 16 and 21. The rear contact edges of the crimping plates 86 are beveled,

as indicated at 92, tofacilitate the crimping action of the'plates on thel wrapper.

After the briquettes are positioned in the Docket of the turret and the ngers 80 and crimping plates 86 have been withdrawn; the briquettes will be carriedupwardly in the direction of the( arrow in Fig. 7 by rotation of the turret. It will be noted that the platform 59 projects beyond the upper guide member so that the briquettesneed, not be discharged entirely from the supporting plat-. lform to permit Athem to be lifted by rotation' pf the turret. `T he pockets in the turret are formed byv fixed contact members 93 and Aspringheld clamps Y94. VThe clamps 94 are shorter, than the members 93 and the members 93 may be -provided ,with recesses 95, as. shown in Fig. 9, to pass the'projecting end of the central supporting portion 96 of the supporting platform 59. When. theV bl'iquettes` areclamped bythe jaws 93 and 94, rotation of the turret wheel will'lift thev Etiquettes fromA the' support 59.

The shaft 86 which ca 'es the turret wheel 85 is driven by 'a Geneva. drive comprlsmg an al'm 9 7 mounted on- :r' shaft 98 and having a collar 99 for holding the driven member ystationary in its various stations. The driven member 100 is secured lto the shaft 86l and is provided with slots 101 for receiving a roller 102 on the arm 97 and with arcuate recesses 103 for engaging the collar 99. The 'collar 99 is provided with a cut-away portion `1.04 to permit thebifurcations forming the recesses 103 to pass the collar during rotation of the driven member by the roller 102. The shaft 98 is driven by a sprocket wheel 105 operated by a sprocket chain 106 which passes over a driving 'sprocket 107 on the main driveshaft 36. The sprockets 107 and 105 are of the same size so that the turret 85 is rotated one step ,l

for each rotation of theniain drive shaft 36. This brings a new pocket into registration with the supporting platform 59 for each pair of briquettes discharged from the platform. After the briquettes are lifted from the supporting platform 59y and transferred to the first station by the vturret 85, the turret rel mains stationaryA while the edges of the wrapper are sealed by a sealing clamp located adjacent the first station stop of the turret above the platform 59. This sealing clamp comp-rises a pair of jaws 108 and 109 shown in open position in Fig. 7 'and in closed position in Fig. 1 0. The j aw 109 is secured' to a collar 110 by a screw 111, as shown more clearly in Fig. 20. The-collar 110 is clamped to a shaft 112 by a cap screw-113. The jaw 108 is provided with lugs 114 atA opposite sides of the collar 110 which are journaled on the shaft 112. A gear segment 115 is also journaled on the shaft 112 and is cbnnected with the aw 108 by means of an arm 116 and a spring 117. The shaft 112 is journaled in the frame 30, as shown in Fig.' 6, and is provided with a gear segment 118 at one side o'f the frame-member 30 and a 122 which engages a plate 123 connected with the vjaw 1109 which permits yielding movement of .the jaw relative to the collar110. It

lis thus apparent that the jaw 109 is yieldingly connected'to the shaft 112 and that the'jaw y108 is yieldingly connectedto the gear seg.- ment journaled on the shaft 112.

A second shaft 124 is journaledin the frame .member 30 in spaced relation to the shaft 112 and is lprovided with a. gear. segment f 125 meshing with the gear segment 118.-. A gear 'msegment 126 is jouraialed on the shaft 124 at shaft 124 in a manner similar to the collar 110 on theshaft 112. AThe jaws 128 and 129 are L position in Fig. 10. A n idler segment 131 is journaled on a stud shaft 132 mounted on the frame 30.. The idler segment 131 has a suiciently wide face to mesh with the gear segments 119 and 126 and the segment 126 also meshes with the segment 115. An operating rod133 is pivoted to the segment 118 at 134 and is reciprocated lengthwise by means of a rocker arm 135 operated by a cam 136 on the main drive ,shaft 36. The operating rod 133 is provided with a spring 137 which permits yielding downward pressure to be exerted on the rod. lVhen the rod 133 is raised from the position shown in Fig. 10 to the position shown in Fig. 7, the shaft 112 will be rotated in a counter-clockwise direction and the shaft 124 will be rotated in a clockwise direction, as viewed in these figures. The aw 109 will move in unison with the shaft 112 and the jaw 129 will move in unison with the shaft 124. The movement of the jaw 129 will be more rapid than that of the jaw 109 because of the inequality of the radii of the gear segments 118 and 125. This will move the jaw 129 out of the way of the jaw 109 so that they will not interfere with eachother. During the upfwardmovement of the rod 133 the gear segment 119 will move the shaft 112 and will rotate the segment 131 in a clockwise direction.

Since thesegment 131 meshes with the seg-- ment 126 the segment 126 will move in a counter-clockwise direction to throw the jaw 128 upwardly to the open positionshown in Fig. 7. The segment 126 meshes with the segment 115 so that this segment will move'clockwise to throw the jaw 108 outwardly into the position shown in Fig. 7. In other words, both' sets of jaws are open during the upward movementof the rod 133 and by reverseactionare closed during the downward movement of the jaws. The cam for operating the rod`133 is shaped to close and open'the ja'ws during the pause ofthe turret, the jaws remaining open during thesmovement of the turret. h v

Each of the jaws 108, 109, 128 and 129 is provided with a recess 138 shown best in Figs. 19 and 20 for receiving the briquettes 48. Surrounding the recesses 138care gripping members 139 which clamp the projecting edges of the wrapper l70 and squeeze the edges together aboutlthejbricjuettes, as shown in i these figures. The clamping members 139 of the` jaws 108 and 109 are provided with heatingD elements 140 which are in the form of electrical resistance wires supplied with current from leads v141 which extend through the shaft 112. i

The projecting edges of the wrapper are squeezed together and at `the same time the wax orothermaterial with which the wrapper is treated is softened bythe heat of the ele ments 140 so that the edges of the wrapper are j sealed together, completelyl closing the vWrapper and forming an air-tight package, The

f flanges 1 folded fla At the time that the edges of the contact members 139 of the jaws 128 and 129 are not heated but act as chilling devices by means of which the melted wax is again hardened so that the flaps will not be separated by further manipulation.- The jaws 128 and 129 are referably provided with radiation fins 142 or dispersing the vheat from the jaws and keeping them cool. In this way the project- 'ing edgesof the wrapper are first heat-sealed together and thereafter chilled to insure that the sealed parts will remain together.

'After the wrapper has been sealed `and .cured to a shaft 146 adjacent the station at which the package is brought to rest is a creaser 147 having creasing flanges 148 at each end thereof for pressing the folded p0rtion of the wrapper against theends of the wrapped article. The flanges 148, as shown in Fig. 15, are` spaced apart an amount correspondingto the length of the package so that when the creaser is moved against the side of the package the flanges will extend adjacent the ends of the package andpress the folded flap to a positionagainst the end flaps.l The end flaps are later folded over the ends of the package and the creasing process is for the purpose of preventing vthe folded edge flap from bulging backwardly when the endlaps are folded over. The wiper holds the edge ap in folded position; as shown in Fig. 12,

.while'the creaser-147 rotates in a counterclockwise direction causing the creasing to approach and contact. with the flanges' 148 reach the center line of the package the turret begins its forward movement` P and the yturret and creaser travel together to carry-the package between the end. folders 149. The position of the package between the end folders v149 is shown more clearly in Fig.

13 and the creases formed bythe creasing flan es 148 are indicated at '150. Y

T e lfinal movement of thepackage by the turretcarries the package to a position diametrically opposite the first position. .In

this nal position the package is brought into alinement with an opening 151 between upper Y I' and lower guides 152 and 153, respectively. A pair of discharge fingers V154, one at each side of the turret, discharge'the package from the turret into the opening 151.' The upper guide 15,2 is'provided with tapered recesses 155, one at' each side of the guide, for receivmain drive shaft 36. 'The lingers 154 carry.

the package entirely through the opening 151 and discharge it into grippers 157 on a turret 158 secured toa shaftr 159. The shaft 159 is rotated in= unison with the shaft 86 by means of a gear 160 on the shaft 86 and an idler 161 on a stud shaft 162. '-Ihe shaft 146 is rotated by a chain of gears 163, Fig. 1, which are driven by a gear'on the shaft 164 whichcar-v y ries the uppermost sprocket 165 driven by the chain 10.6. An outer wrapper 166 is inter-v posed in a guide 167 extending transversely of the passage 151 and this outer wrapper is folded about the forward edge of the package 'as it passes through the opening 151. The 'Wrapper extends suiiiciently above the opening 151 so that the top flap of the wrapper will extend outwardly away from the package, as shown in Fig. 7. The rear face of the projectingflap is-treated with a small amount of adhesive material by a swinging arm 168 or other suitable pasting mechanism. The wrapper is discharged from the turret 158 by a pair' of ngers 169 into a passage 170 having a spring guide 171 at the top thereof. The

which folds the projectingflap backwardly against the edge of the passage and glues the flap in place, thus placing an outer wrapper about the sealed package. A magazine is provided a-t the end of the passage 170 and a rolower end of the magazine and raises the l packages into the magazine as they reach the end of the passage 17.0. The camdisc 174 is secured to a shaft 175 connected by spur gears to' a -.shaft. 176 which'l is provided with a sprocket 177 driven by the sprocket chain 106.

The lingers 169 are carried on arms 178 which are connected by links 179 to the arms 156 so that the arms 17 8l and thearms 156 are oscillated in unison with each other.

' The operation of the various partshas been explained. in connect-ion with` the decription of the parts so that a detailed descriptionv of the operation of the machine is thought t0 be unnecessary. Briquettes are 4deposited in the hopper' 84 andare automaticallywrapped in treated wrappers 'which are "sealed by pressing together the projecting edges of a wrapper, after which the edges are folded against the package and ai band or outer wrapper is placed in lposition to hold the folded edges in place. The briquettes are assembled in packages' of two briquettes each,
