The machine hereinafter described, as one embodiment of my invention, is adapted to Wrap a row of substantially flat circular disks, such as hard candies or the like, as illustrated in Fig. 21 or, with but slight change, to wrap a plurality of rectangular articles as shown in Fig. 22, a thin rectangular bar as shown in Fig. 23, or a plurality of rectangular bars as shown in Fig. 24. The machine will first be particularly described as adapted for wrapping the circular disks or candies illustrated in Fig. 21.

As it is very desirable to thoroughly protect certain varieties of candy that may be wrapped by the machine from atmospheric moisture, the machine has, in the present instance, been designed to wind a waxed paper wrapper twice around the peripheral surface of a row of candies with peripheral portions of the wrapper overlapping, and with the ends of the wrapper projecting a distance beyond the ends of the row. The projecting end portions of the wrapper are closed over the ends of the row by first bending inwardly or crimping the projecting ends on two opposite sides thereof, as shown in Figs. 29 and 30, flattening the projecting ends as shown in Fig. 31, bending downwardly the projecting ends as shown in Fig. 32, laying the downwardly bent ends over against a. side of the package as shown in Fig. 33, and by securing the bent over ends of the wrapper against the side of the package by heat sealing or by the application of a band or label.

Referring to the drawings the right and left frames, designated by the numerals 2 and 4 respectively, provide bearings for the various cam shafts and a support for the table 6 bolted thereto. Bolted to the upper face of the table is an upright frame 8 carrying a magazine for holding the candies, a roll of wrapping material, wrapper feeding mechanism, a pair of shear knives and a support for the candies in the magazine.

As shown in Figs. 1, 4 and 5, the magazine comprises, in the present instance, three seamless steel tubes In, brazed or soldered in vertical position to the support bar I2, secured to the bracket l3, which is bolted to the frame 8. The tubes l8 have diameters slightly larger than the diameters of the candies and have slots or openings 44 cut in their outer faces to facilitate charging the magazine with the candies. As the tubes ll! are open at their lower as well as their upper ends, a plate or shelf l6, fastened to the bracket l8, bolted to the frame 8, provides a support for the candies in the said tubes.

The bracket 8 is provided at its upper end with a bearing for the stud shaft on which is mounted for rotary movement the spool 22 carrying the roll of wrapping material 24. The spool and roll are prevented from over-running by any suitable friction device 25 engaging the spool. The web of wrapping material 21 is drawn from the roll and passed downwardly over a. suitable guide roll 26 and between the feed rolls 28 and 38. The feed roll 28 has one end of its shaft journaled in the frame 8 and the other in the bracket 32, rigidly secured on the ends of the

stud shafts

34 and 36, the opposite ends of which are rigidly secured in the frame 8. The feed roll is journaled in the

arms

38 and 40 mounted for swinging motion on the stud shaft 36. The upper ends of the

arms

38 and 40 are provided with bearings for the rock shaft 42 to which are rigidly secured the hand-operated levers 44. The links 48 are pivotally connected at one end mid-way of levers 44, and at the other end are pivotally connected to the bell cranks 50, pivotally mounted on the stud 52 secured in the frame 8, and the stud 54 secured in the bracket 32. Coiled springs 58 tend to turn the bell cranks 50 in a counter-clockwise direction, viewing Figs. 2b and 4. With this construction, when either of the hand operated levers 44 is swung downwardly into the position shown, the links 48 are positioned below the pivotal bearings of rock shaft 42, which permit the springs 58 to act through the bell cranks 50, links 48 and levers 44 to turn the

arms

38 and 48 in a direction to press the movable roll 30 toward the other roll 28. A laterally projecting pin 60 on each of the levers 44 enters a notch on the under side of the links 48 to lock the links and levers together in the position shown. The feed rolls may be separated by merely swinging upwardly either of the hand-operated levers 44.

The shaft of the roll 28 projects through the frame 8 and has secured to its projecting end the pinion 62, as best shown in Figs. 6 and 7. The shaft of the feed roll 3!] projects a considerable distance beyond the supporting arm 40, passing behind the frame 8, so that a pinion 64 secured to its outer end is in line with the pinion 62. These pinions are smaller in diameter than the diameters of the feed rolls, so that when the feed rolls are engaged the teeth of the pinions do not touch. The

stud shafts

34 and 36 project a distance through the frame 8 and have their projecting ends turned to a smaller diameter to provide bearings for the idler gears 66 and 68.

The brackets I3 and I8 Figs. 1 and 2b, provide bearings for the rack I0, which is given vertically reciprocating motion by the links 12, bell crank 14 mounted on the shaft 15, cam roll 16 and cam 18 secured to the shaft 88. A gear 82, Figs, 6 and 7, secured to one end of the shaft 84 meshes with the rack 10, and is thereby rotated alternately in opposite directions, one full revolution. To the other end of the shaft 84 is secured an arm 86 carrying a stud 88 on which is mounted a pawl 90. A gear 92, meshing with the idler gear 68, is mounted loosely on the shaft 84 and is riveted to the ratchet 94. This ratchet has a single tooth or notch adapted to be engaged by the pawl 98, and it will be evident from an inspection of Figs. 6 and 7, that as the rack 10 moves upwardly the pawl 98 will engage the ratchet 94 and cause it to make one full revolution in a clockwise direction, viewing Fig. 7. This rotary motion of the ratchet is transmitted through the

gears

92, 88 and 66 and

pinions

62 and 64 to the feed rolls 28 and 30, causing them to make one full revolution in a direction to feed the web of wrapping material downwardly. The diameters of the feed rolls are such that at one revolution they feed just enough wrapping material for one wrapper. It will be evident that as the rack 18 moves downwardly the pawl 90 will ride on the ratchet 94 without imparting motion thereto. As the web of wrapping material is fed downwardly it is guided between the blade 96, and shear knife 98, by the guide bars I08 and I02, secured in vertical position in the support bars I04 and I86, secured to the bracket I08 which is bolted to the frame 8.

The stationary shear blade 96 is rigidly secured to the bracket I88. The co-operating blade or knife 98 (Figs. 1, 4 and '7) extends through an opening 99 in the frame 8 and is secured to the epe ts;

:providedwith: two look nuts II3. --A-spring II4 coiled=about the-threaded portions of the pivot vpin andi'having its-lower end resting onthe #bracket II5, and its upper end pressing against the under side of the 'lowerlock nut-urges the pivot: pin I18 and consequently the shear knife :98 upwardly, and causes the knife to press closely against'the shear blade 96.

To the righthand end: of the shear knife 98 is attached a'roll H6 engaged by the forked lever H8 secured to one ,-.end-=of the ro'ckshaft I having bearings in the bracket I22. "To theother endof the rock shaft '.?:I2!I. is secured an arm I24 provided at its lower ae'ndwith acam roll I26 working in a groove in 0a 'cam I28'secured to the shaft 88. The cam I28,

: acting through the connections above mentioned,

:givesoperative-motion to the knife '98 to shear I -a=secti0n of wrapping material-from the web after thecorrect length of'web has been fed gdownwardly by the feed rolls 28 and 38. the-cutting off movement of the shear knife'98,

During 1 the upper end 0f a screw I30 rides on an inclined surface I32 on the lower end of the bearing block 4:35. secured to: the bracket I31, so as to tend to wcauseclearance at the right hand end ofthe 1'blades, thus permitting cutting pressure at the left hand endof the blades.

Bolted to: the upper face of the table 6 are I two parallel frames I34 and I36, shown in Figs.

These frames provide bear- Toizone end of the shaft" I38 is rigidly secured 'th'e head casting I 4|] having four projections or rlugsi I42.

'-To each of theselugs are'bolted the ends of two over-hanging bars I44and I46, spaced .apartby the-blocks I48.

Yieldably' connected to each ofthe bars I44 are three short bars or plates I50. isEbestshown in Fig; 9.

The'manner of attaching these plates Four shouldered studs .I5I.:are riveted. to each ofthe plates I50, each .of the studs having a tapped hole in its upper endto receive thebutton head screw I52. Springs I54 tend to push'the'plates I56 away from the rbars I44,- and toward the bars I46, the movement of the :platesI58 being limited bythe heads of the screws I52 whereby the plates I and bars I146 are spaced a suitable distance apart to provide between them channels I'for the articles to be wrapped and'their wrappers. The head casting-I40, andthe above mentioned parts carried thereby, constitute the first wrapper winding -mechanism, which is designated in the drawings by the letter A,=Figs. 21), l, 8 and 9. For conven- -ience,-this and similar mechanisms willbe hereinafterreferred to simply as wrapping heads. The right hand end of the shaft I38 projects -a short.:-distance outwardly beyond the frame I36 and ha5krigidlysecured thereto a four slotted Genevalwheel I56, with the slots facing the frame 436. :Directly below the shaft I38 is another shaft: I-SB haVing-bearings in. the frames I34 and I36. To the outer end of this shaft is rigidly secured a miter gear I60 meshing withthe miter gear I62-rigidly-securedto the shaft I64. To the shaft I58, between-the miter gear I GU an'd the frame :;I,36 is. rigidly, securedra: Gene'vatdriver and locking member I66, provided with a roll I68 adapted to" enter the slots in the Geneva wheel.

It will thus be seen that each time the shaft I64 makes one complete revolution the head I40 is :moved through-90 in the direction indicated by the arrow in, Fig. 9. It will further be seen that the head moves intermittently, with periods of restbetween the periods of movement. The

wrapping heads B, C andD, carried by shafts I10,

I12 and I14 respectively,-are identical withhead A except that these heads have a single pressed plate I16, instead of three plates I59 as in head A. The driving members for these heads are also identical with the driving members for the head A, they-are driven in the same direction and have thesame periods of motion and rest.

To thefront end of the table 6 is bolted a bracket I18, providing bearings for the slide I to the upper side of which is fastened the pusher plate I82.' Thi's'slide is given reciprocating mo- 2 tion' longitudinally of the machine by the cam I 34 through the connections comprisingthe lever I86 pivotally mounted on the bracket I88, the cam roll I90; and the link I92 connecting the upper end of thelever I86 to a bracket I84 fastened to the underside of the slide.

'Bolted to the upper left hand side of the table 5 are three brackets I96, I98 and 288. brackets provide bearings for the slide bar 292,

which is given reciprocating motion longitudinally of the machine by the cam 2B4, rigidly secured to the shaft 206. This shaft has rigidly secured to its right hand end a miter gear 288, meshing with the miter gear 2H)," rigidly secured to the shaftZ I2. The connectionsthrough which the earn 204 actuatesthe slide bar 282 comprise thecamroll 2il,"the lever 2H5 pivotally mounted on the frame 4, the link 2I8, connecting the up per end of the-lever'2I8 to the block 220 rigidly secured to the slide 282. The slide bar has rigidly s'ecured thereto-a plurality-of pusher bars or fingers 222,224. 226, 228, 230, 232, 234 and 236, the function of which is to push the partly formed packages from one wrapping head or other rotary mechanism into the next.

Figs. l and 5 show the first wrapping head A, the Webof wrapping material 21, the shear knife 98 and'the pusher plate I82 in their relativepositions as the pusher plate is just starting to push the lowermost row of candies from beneath the three stacks in the magazine, into a channel I55 of the wrapping head. The movements of the parts are so timed that as the row of candies reaches the web of wrapping material a section of the material is cut on by the knife and carried movement by the lower ends of the tubes, and 1 when the pusher plate is returned to starting position the stacks will drop down on the supporting plate I6. Due to the thickness of :the walls of the tubes IiL'the stacks of candies there in are spaced somewhat apart. Before wrapping a row of candies it is desirable to bring the can'- -dies together-with their edges touching. Fol-this purpose, the pusher plate I82, Figs. Sand 5a, is

made with flaring sides I83,:which cause the two end candies-ma row to be pushed laterally toward These the middle candy as shown in Fig. 5a. The bar I81 fastened to the bracket l8 prevents upward. displacement of the candies as they are pushed. from the magazine to the wrapping head.

The shear blade and its co-operating knife arelocated at such a distance from the plane of thepath of the candies that when the candies and. wrapper are pushed into a channel I55 of the: Wrapping head the wrapper will cover three sides. of the row of candies as shown in Fig. 25, with, sufficient unused wrapper material 238 projecting out of the channel to make two complete wraps. around the candies. After a row of candles and.

their wrapper have been pushed into a channel.

of the wrapping head A at station K, as shown in Fig. 4, the head rotates through an angle of 90, carrying the partly formed package to station L, the feed rolls feed downwardly sufficientwrapper material 21 for another wrapper and. the pusher plate is returned to the starting position, these movements occurring synchronously- It will be observed that when a row of candies has been pushed into a channel of the wrapping head A and the head rotated to bring the row tothe station L, the open mouth of the channel faces downwardly. It is necessary, therefore, toprovide means to prevent the candies from falling out of the channel while the channel is at, or is moving to or away from this station. The spring pressed plates I59, Figs. 8 and 9, serve thispurpose. Each plate being independently spring pressed, and being of such size as to cover one candy only, each candy in a row is held securely in place, even when there is a considerable varia tion in the thickness of the individual candies, These plates serve further to cause the wrapper to be tightly drawn around the row of candles as the row is pushed into a channel I55.

It will be observed that when a row of candiesand their wrapper have been carried from the station K to the station M by two successive ro-- tary movements of the wrapping head A, the un wound portion 238 of the wrapper hangs downwardly across the mouth of the channel I55, ccn-- taining the row, and that this channel is in align-- ment with a similarchannel in the head B. Itwill be seen, therefore, that when the slide bar 202 is moved rearwardly by the cam 204 the pusher finger 222 will push the candies and their wrapper from the channel in the head A into thechannel in the head B. This results in the wrapper being wound around two more sides of therow of candies as shown in Fig. 26. As shown in Fig. 26 the wrapper has been wound one full turn around the row of candies. and as the row is. moved, by two successive rotary movements of the head B, from the station M to the station P, Fig. 12, the candies and wrapper are prevented from falling out of the channel containing them by the single spring pressed plate I16, which is of sufficient length to bear on all of the candies in the row.

At the station P, the partly formed package that has just been described as having arrived at that station, is pushed by the finger 224 from its channel in the head B, to a similar channel in the head C, causing the wrapper to be further wound about the row of candies as shown in Fig. 27. When the head C has carried the package to the station Q, the finger 226 pushes it into a channel in the head D, completing the winding of the wrapper about the candies-as shown in Fig. 28.

Referring to Fig. 11, it will be observed that the

pusher fingers

226 and 228 have cut out portions 239leaving rearwardly extending portions 240 and 1242 which are V shaped in cross section, as shown :in Fig. 12. The object of forming these portions in this manner is to cause them to bend inwardly -or crimp the projecting ends of the wrapper as .shown in Fig. 11. As the pusher finger 226 pushes .a package from the head C to the. head D, the projecting ends of the wrapper are crimped on the .front side of the package. When the package is .moved by the head D to the station R the crimped .side of the wrapper will face rearwardly so that when the package is pushed by the finger 228 from the head D to the head E the wrapper on the .;rearward side of the package will be crimped correspondingly, as shown in Fig. 29.

After a wrapper has been fully wound about a :row of candies and the projecting ends of the wrapper crimped as shown in Figs. 29 and 30, it is required to close the projecting ends of the wrapper as shown in Fig. '33. This is done by first flattening the projecting ends of the wrapper as shown in Fig. 31, then bending the flattened end portions downwardly as shown in Fig. 32 and :finally, by turning over the flattened end portions against the side of the package as shown in Fig. 33. The mechanism for effecting these operations, which may be designated as wrapping head IE, will now be described.

Referring to Figs. 2b, 3, 14, 14a and 15, the head casting 244, the shaft 245 on which it is secured, the gears and Geneva members for driving this shaft are exactly the same as corresponding parts of the first wrapping mechanism designated by the letter A, except that the bevel gear 241, rigidly secured to the shaft I64, is located at the left of :its mating gear as viewed in Fig. 3. The object of this arrangement, of the gears is to drive the head E in a counter-clockwise direction as viewed in Fig. 14 To each of the four lugs 246 of the head casting 244 are bolted offset bars 248, to the offset ends of which are secured by screws, thin plates 258. Also bolted to the lugs 246 and spaced from the bars 248 by spacers 252, are four other offset bars 254 corresponding in shape to the bars 248. The offset ends of these bars carry spring pressed plates 256, secured to the offset ends of the bars in exactly the same manner as the spring pressed plates in wrapping heads B, C and D. As in the wrapping heads already described, the

plates

250 and 256 are spaced apart to provide between them a package receiving channel 251. To frame I34 is bolted a bracket 258 to which is bolted a bar 260. To this bar is bolted two blocks 262 provided at their lower ends with hinge pins 264. Mounted on these pins, for swinging action, are two blocks'266 having riveted thereto two semi-circular plates 268. To the outside of these plates, at their forward ends, are riveted two blocks 216, having their lower faces in about the same plane as the lower faces of the spring pressed plates 256, when the head E is dwelling to receive a package from the head D. The two semi-circular plates 268 are spaced apart a distance approximately equal to the length of a row of candies. This distance may, however, be regulated by the adjusting screws 212, carried by the bar 260 and engaging the pins 214 driven into the blocks 266. A coiled spring 216 connecting the two blocks 266 tends to draw the two semicircular plates 268 towards each other and cause them to bear with yieldable pressure against the ends of a package as will be more fully described.

A forked member 218 is rigidly secured to the upper end of the vertically reciprocating rod 280 connected by the link 282 to the bell crank 284 provided at its lower end with a cam roll 286.

. side ofv the package as shown in Fig. 28.

' rigidly secured to the shaft 206.

, wise direction as shownin Fig. 14.

The roll 286 works in a groove in the cam 288, The upper ends of the forks of the member 218 have fiat smooth surfaces corresponding in size to the underside of the blocks 2T8 riveted to the forward ends of the semi-circular plates 268. When a partly formed package, as shown in Figs. 29 and 30, is

, 210. The cam 283 then moves the forked member downwardly out of engagement with the blocks 2'") and the head E is rotated in a counter clock- It will be apparent that as the head E rotates in the direction shown the projecting ends of the wrapper will be bent downwardly by the plates 2G8, which'being yieldably spaced, cause the wrapper to be bent on lines coinciding with the ends offthe row of candies. i

When a package has been carried by the head E. to the station S the bent over end portions of the wrapper 292 will project upwardly as shown by dot and dash lines in Fig. 14. It is next required to bend the upwardly projecting portions down againstthe side of thepackage, and the mechanism for accomplishing this'will now be described. The bell cranks 29A mounted for rocking motion on the brackets 285 have secured totheir upper ends thin plates 296 as best shown in Figs. 14 and 14a. These plates 2% are adapted when the upper arms of the bell cranks 294 are moved towards each other, to tuck the upwardly projecting ends of the wrapper 292 over against the side of the package. The bell cranks 294 are given rocking motion through the link 298, Fig. 2a, bell crank 259 pivotally mounted.

when the row was pushed from the channel in the wrapping head C to a channel in the wrapping head D, and that the peripherally overlapping portions of the wrapper are on the under- It will be apparent, therefore, that when the pack-v age has been carried by the head D to the station R, Fig. 12, the overlappingperipheral portions of the wrapper will be on the upper side of the package, and that when the package has been carried by the head E from the station R to the station 5, Fig. 4, and the projecting end portions turned over against the side of the package as described, they will be turned over against the side of the package opposite the overlapping peripheral portions of the wrapper. This is desirable in order to draw the overlap ping peripheral portions tightly together where they are bent over the ends of the package. When articles are wrapped in this manner and the bent over projecting ends of the wrapper secured against the side of the package, Very good protection is afforded the'wrapped articles even without heat sealing the package.

It will be obvious that'in some cases it may be desirable to wrap an article or articles in a wrapper of waxed paper, or other material having a waxed surface, and seal the bent over ends articles to be wrapped. v In such cases awrapper of either waxed or Lin-waxed material maybe used, and the bent over ends of the wrapper secured against the side of the package by the application of a band or label. The machine has, therefore, been provided withrneans where-iv articles may be wrapped in either manner. The said means comprise a heater for'melting the wax of the wrapper when a waxed Wrapper is used, mechanism forholding the package under pressure while the melted wax is, cooling, and

a device for wrapping a band or label, about the package with the ends of the labeloverlapping and glued or pasted together. As the machine is constructed and operated, packages will pass through the heating and labeling de-;.'

vices regardless of whether or not the heating device is supplied with heat or thelabeling device with labela It is therefore possible to wrap articles in the manner described, heat seal'the packages, and pass-the sealedv packages through the labeling device, applying or not applying a label as may be desired. It is also possibleto pass the packages through the heatingid'evice w' hout applying heat thereto, and then' apply a band or label as theypass through the label-l.

A shaft journaled in the frameslSdfand 5355, has rigidly secured to its right hand end viewed in Fig. 1.3) the head casting',342

having four lugs Sti l. To each oi'these lugs are bolted overhanging bars 3%, spaced slightly away from the lugs by thenonheat conducting washers 348. Riveted to the bars 346, 'butspaced therefrom by the blocks 358, are plates 352. TOI' each of the plates Mtand 352, aresecuredby screws 354, flat electrical heating elements 356, each having a terminal a at one endand another b at the opposite end. The object of spacing apart the bars 346 and the plates 352 is to.

provide between them package receiving pockets 358. their inner ends, the object of which is toq' provide abutments 366 to limit the distance a package can be pushed into a pocket. essary because, in this instance, thep cketsare made wider than the thickness of a package, and

do not frictionally engage the sides thereofias such frictional engagement would t'endto displace, rearwardly, the turned over ends of the.

Thefheating device rot-ates intermittently and ma coun continuously through the heating elements '356 While they are moving as well as while they are dwelling. To accomplish this the followingde scribed connections are provided. To the'frame I34 is bolted a bracket 352 bored for'two'fibre bushes 3'64.
