To all whom it may concern:

Be it known that ll, HARRY Y. ARMSTRONG, a citizenof the United States, and a resident of Elgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Gum-Wrapping Machines; and l do hereby declare that the following is a full, clear, and exact description thereof,-reference being had to the accompanying drawings, and to the characters of reference marked thereon, which forma part of this specification.

This invention relates to improvements in wrapping machines. v y The, machine herein illustrated has been designed for wrapping flat, thin articles, such as sticks ofgum," and in the-following description the features of construction and operation will be specifically referred to with respect to such a machine, although it will be u nderstood that "some ofthe features illustrated and described-may be employed for wrapping articles of other sizes and shapes. The machine shown is also designed to wrap articles with an inner and an outer wrapper, the inner wrapper being usually a thin, light paper, such as oil paper, and the outer wrapper a heavier paper on which is printed the label of the article. i

The machine herein shown is designed more specifically for. wrapping individual cakes, which are known as vending machine cakes, in which the outer wrapper is made only .of' sutlicient length to cover theinner wrapper but is not provided with end flaps to inclose the ends of the package.

Among the objects of the invention is to provide a compact and simple wrapping machine which is capable of being operated at a high speed to eiiiciently wrap articles, such as chewing gums, and the invention consists in the matters hereinafter set 'forth and more particularly pointed out in the appended claims.

In the drawings :Figure 1 is a partial side elevation, with parts broken away, of a wrapping machine embodying my invention. Fig. 2 is an enlarged side elevation of part of the machine shown in Fig. 1. Fig. 3 is a partial side elevation and partial central vertical section of the machine. Figs. 4 and 5 are horizontal sections on the lines 4-l and 5-43, respectively, of Fig. 2.-

Fig. 6 is a vertical section on the indirect line,66 of Fig. 2. Figs. 7 and 8 are detail vertical. sections on the lines 77 and 8 8,respectively, of Fig.2. 'Fig. 9 is a detall section taken on the line 9-9 of Fig. 4. Fig. 10 is a fragmentary detail of'the pri mary wrapper head and the parts associated therewith. Fig. 11 is a fragmentary perspective viewof the end folding mechanism for the inner'wrapper, located in advance of theprimary'wrapper head. Fig. 12 is a perspective view of the primary wrapper head separated from its cotiperating parts. Fig. 13 is a perspective view illustrating'the secondary wrapper head, a portion of the pasting mechanism and a portion of the tertiary folding slot. Figs. 14: and 15 are fragmenta'rysectional views of the secondary wrapper head and associated parts of the secondary and tertiary folding slots. Fig. 16 is ahorizontal section on the line 16-16 of Fig. 2. Fig. 17 is a horizontal section on the indirect line 1-717 of Fig. 2. Fig. 18 is a vertical section on the lihe 1818 of Fig. 2.

The machine is mounted on' a base or pedestal20 which carries upright webs or flanges 21, 2Lwhich support the wrapping mechanism and the bearings for the various operating shafts.

22 designates the main operating shaft of the machine mounted in bearings carried by the webs 21 at the front end of the machine a vertical hopper 26 suitably supported over the primary folding slot 28 formed between upper and lower plates 29, 30, respectively. The lowermost gum of the stack rests in the primary folding slot and the gums are ad? vanced through said slot from the lower end of the stack by means of the primary plunger 32 which reciprocates in the slot and through the lower end of the hopper. The said plunger 32 is attached to the upper end of and moves with a vertically arranged cross head 33 at the side of the machine which is apertured at vertically spaced points to fit over the reciprocabi'e rod 35 and guide rod 36. The head is attached to the reciprocable rod in any suitable manner. The guide rod 36 is mounted at its ends in bearings 37, 37 carried by the machine frame.

The actuating rod 35 slides in bearing in the "bearing members 38, 38 carried by the machine frame. The rod 35 is reciproeated by power derived from the main operating shaft 22, through the medium of the crank 39 on said shaft and a pitman or link 40 1 pivoted at-one end to said crank and at the other end to a head 42 attached to the forward end of the rod 35.

The gums are forced by the plunger 32 through the slot 28 into the alined pocket of an intermittently rotative wrapper'head 46 (Figs. 1, 2, 3, 10 and 12) arranged at the delivery end of the slot 28. Said primary wrapper head 46 is formed on or carried by one end of a rotating shaft 48 that is mount-j ed in a suitable bearing 49 on the adjacent web 21, as best shown in Figs. 4 and 10. Said wrapper head embraces a. central body portion having at its upperand lower sides hooksor flanges 50, 50 between which and:

the centralbody of the head are "formed the gum receiving pockets 45. Each'side of the head is centrally slotted to receive a spring pressed member 52 which is pivoted to the body and which extends over the pockets, and their free ends are pressed toward the bottom of the pockets byspri-ngs 54 so as to hold the gums in the pockets, as best shown in Figs. 3 and 12. Said primary wrapper head 46 is narrower than the'length of the gums, while the wrappers are longer" than the gums. The shaft 48 which carries theprimary wrapper head is formed at the side of the head with rectangular enlarge ments 63, 63 .to support the extended end flaps of the wrappers. The forked ends of the primary plunger extend over these en-' largements at the forward. limit of their throw and said enlargements are cut away at 64, 64 to permit the head to begin to rotate before the plunger clears the same in its retractive movements. The pocket 45 at the upper side of the head faces toward and is normally in line with the folding slot 28,

while the pocket at the lower side of the head faces oppositely to and is in linewith a secondary folding slot associated with the end flap folding mechanism. The latter slot is formed between upper and lower" plates 61,62, respectively. The

constitutes the floor of the slot 60, and ex.-

plate 62 by a suitable feeding and cutting .mechanism, designated by 65, which need not be here described. The upper wall 29 of the primary folding slot is notched at 66 to permit the cut wrappers to be fed-across the said slot'and into the path of the gums. The rear end of the lower-wall of the slot 28 is formed by a block 30 suitably attached tothe upper wall as by the screws 30 (Fig.

2) and between" said block and the wall 30 is formed aspace to receive the lower portions of the wrappers. The, cut wrappers are supported in this position by the stop or stops 67 carried b the block 30'. When the advance edge 0- the gum, urged for- "ward by'the plunger 32, strikes the inner ment is rearward with regard to the machine itself; that is, the gum magazine 26 is regarded as positioned at the front of the machine and the stacker 235 at the rear of the machine.

I may provide means for creasin the end flaps at their rear edges as they l eave the primary folding slot,- in the manner indicated at a in Fig. 10, so as to thereby tuck in the material of the .fiap and avoid too great fullness, or a-bunching effect of the wrapper, when the end flaps are folded against the sides offthe packages. This may be effected by providing the primary plunger at its lower margins with grooves 68 which open entirely to the forward ends of the plunger, and providing creaser plates 69, one at each side of the primary folding slot, attached to the wall of the slot in any suitable manner and adapted to extend toward-each other into the slot. As herein shown, the creaser plates 69 are carried by a bracket 69 attached to thejrear face of the block 30. The horizontal portion of the bracket is extended toward the wrapper head 46 to support the wrapper while being passed to said head. The said creaser plates areformed at their inner ends and at their forward sides with curved edges which are arrangedin line with and are adapted to cooperate with the grooves 68 of the plunger to crease the end flaps in the manner shown in Fig. 10.

After the partially wrapped gum has been thus delivered to the primary wrapper head 46 said head is .partially'rotated to bring the pocket carrying the same in linewith the secondary folding slot 60 and to bring the other pocket thereof in line with the primary folding slot 28 to receive another gum and wrapper in the next forward movement of the plunger 32. The said plunger 32 is notched at its-forward end. as indicated at 70 in Fig. 4, to snugly receive the gum r till so as to thereby'h'old the gum. laterally' provide the delivery end of the lower wall of the primary folding slot, formed by the block 30, with a. spring pressed dog '72, the rear end of which plays upwardly through the slot 7 3 formed in the said block, so that the free end of the dog is slightly above the lower wall of the slot. The dog yields downwardly against a spring 746 to permit a gum to pass by the same into an alined pocket of the primary wrapper .head, and after the gum has passed the dog it springs upwardly into a central notch formed in the plunger 32, so as to bring the free end of the'dog in front of the gum. The free end of the dog, I

at this time, constitutes a stop to prevent the gum being retracted with the plunger,

lWhen the gum and its wrapper have been delivered in alinement with the secondary folding slot 60, as most clearly shown in Figs. 3 and 7, the free side marginof the wrapper bears against a bar 78 arranged transversely across the end of the upper wall plate 61 of the secondary folding slot, and made of a length greater than that of the wrapper. The said bar is fastened to the wall plate 61 in any suitable manner, as by the screws 7 9 shown in Fig. 11. The free margin of the wrapper is thus held throughout its length in advance of the gum so that when the gum is advanced by the means hereinafter described, said margin is folded over the upper side of the gum to complete the side folding thereof. The said bar 78 is provided exterior to the secondary folding slot with down-turned ends .82 provided with inwardly turned parts 82 formed with oblique folding surfaces 83, the lower inner portions of which are substantially'in the plane of the upper surface of the bottom wall plate62 of the secondary folding slot. The down-turned portions 82 are spaced apart agdistance greater than the length of the inner wrapper, thus permitting the wrapper and gum to pass freely between the same. Fixed to the sides of thesaid lower wall plate, as by the screws'84, 84 are end folding plates 85, having upwardly facing oblique folding edges 86, 86, the lower or forward ends of which, at the forward ends of said plates, are substantially in the plane of the upper face of the lower wall of the secondary folding slot and the inner lower parts of the folding surfaces 83 of the bar 78, as best shown in Fig. 11. The upper wall plate 61 is narrower than the lower wall plate 62 between said folding plates 85 so as to thereby leave spaces 61f through which the upwardly. folded end flaps of the wrapper may pass, as shown in Fig. 8.

The sides of the upper wall plates of the secondary slot, abreast of-the folding plates 85, 85 are provided with creaser plates 61' which eiitend slightly below the level of the upper wall plate so asto crease the end flaps of the inner wrapper at the bases of said flapsand thereby facilitate the folding of the said'flaps upwardly about the package. The transverse bar 78 may be arranged at ,its inturned portions 82to bear against'one set of screws 8401? the folding plate 85, as best shown in Fig. 11,.so as to support the forward or receiving end of'the upper wall plate 61 on'said screws, and prevent said latterplate tilting upwardly at its rear end in a manner to tilt the forward end thereof downwardly which would result in obstructing or partially closing the receiving end of the secondary folding slot. 1

The upper wall plate 61 of the secondary folding slot is provided in advance of said folding plates '85 with recesses 8'? arranged at the sides of the longitudinal center of the plate, and these recesses have converging exterior side walls 88, 88 to constitute folding surfaces to fold'the upwardly extending end flaps of the wrapper downwardlyagainst the flat top side of the package as it progresses through said slot, The said recesses are arranged at their-forward inclined folding margins 88 substantially in the planesof the innerisides of the folding hill plates 85 so as to smoothly guide the wrapper end flaps from the folding plates onto the folding edges constituted by the converging recesswalls. The lower wall plate 62 of the secondary folding slot is formed in rear of the folding plates 85 with marginal upstanding ribs 89 on which the widened rear portion of the upper wall plate rests, thus forming in the lower wall plate between said ribs a depression for the package of gum and wrapper, as best shown in Fig. 9. The said oblique side walls of the recesses 87 taper gradually inwardly toward their rear ends overthe ribs 89 so as to form overhanging portions 90 to gradually bring the upstanding end flaps, shown inv Fig. 8, flat down on the" upper side of the package, as shown. in Fig. 9f 'ijz-The intermediate portion 90 of the top wall plate is narrower than the distance apart between the folded down wrapper ends so as not to interfere with the discharge of the package from the secondary folding slot. The said gum and wrapper are forced from the primary wrapper head and into the secondary folding slot by means of a secondary plunllhli the primaryplunger, it being shown as fixed to a ledge or flange 93 of the cross head 33.

The stroke of the plunger 91 is ofsuflicient length to carry the wrapped ums from the secondary folding slot into the slot 95 ofa secondary. wrapper head 96 which is mounted on or carried by a .shaft 97 that is rotatively mounted in suitable bearings 98'supported on the web 21; The slot 95 of said secondary. wrapper head is normally in line with the secondary folding slot.

space or recess to receive an outer wrapper 6, adapted to be fed into said space or recarried by the magazine. 106 is driven. from the shaft'99, by the mcess from the wrapper feed mechanism.

The wrapper vfeed mechanism embraces amagazine "98-, that is pivotally supported on a shaft.99 mounted in the frame of the termeshing beveled pinions 108, 109, as shown in-Figs. 1 and The construction described permits the forward end of the magazine and the roller carried thereby to be swung upwardly so as to carry the roller away from the wrapping mechanism beneath the roller. in its lower position by means of a split lug I 410 which depend therefrom at its inner side guide the wrappers from the roller to the in overlapping engagement with the lug 411 on the frame, and a clamp bolt 412 extends through. the split lug and, is screw-threaded to the lug 411. The split lug is clamped against the lug 410 bya shoulder 412' on the bolt. The said bolt is provided with a.

handle 413 bywhich it may be'turned into and out of clamping position.

The magazine is provided beneath the forward end thereof and in rear of the stripper roll with a guide member 110 to wrapper receiving recess below. j There also provided just in front of the upper end of the wrapper recess and in rear of the stripper roller a. guard 111, (Figs. 3 and, 11) which is herein shown as fixed to the rear end of the upper wall plate of the secondary folding-slot. jThis guard avoids tendency of the wrappers following the a stripper roller and insures accurate delivery of the outer wrappers into the wrapper receiving recess below.

jing plate 122 lies at the rec ing recess is inclosed by side walls 114, 114 and a curved front wall 115 which is formed on or carried by a bracket 116, and the wrapper rest or support is formed by a member 117 which is attached to and extends forwardly beneath the bracket 116.

As a further and separateimprovement, the secondary wrapper head is. formed at opposite sides of its slot or pocket, and

adjacent to the ends thereof, with curved horns 120, 120, the outer surfaces ofwhich are curved concentrically to the axis of 'rotation of 'the secondary wrapper head. These horns are notched at 121 to clear the finger '217 hereinafter described. The side walls of the wrapper receiving recess are curved at their upper sides to correspond to the exterior curvature of said horns and one of the horns, in the normal position of the wrapper head, lies in a position to constitute, in effect, a portion of the rear wall of the wrapper receiving recess, and serves to guide .the wrapper to the bottom or wrappersupport of the recess, as best shown in Figs. 3 and 14.

The pocket of the secondary wrapper head 96 is herein shown as made longer than the width of the gums which pass therethrough. \Vithin' saidpocket is located a floating plate 122, best shown in Figs. 3, 14 and 15, which is made of a width approximately one-half of the length of said pocket. Said plate is adapted to slide from one end to the other of the pocket, and is held in place and is guided in its sliding movement by means of a pin or stud 125 which. extends downwardly through an opening in one wall of the pocket to engage a plate is provided with a hand piece or projection 1.28 by which the plate may be removed when the guide stud is released there- In the operation of the secondary wrapper head and 'the secondary plunger to apply theoiiter wrapper to the packages wrapped with the inner wrapper, the floativing end of the pocket, when the wrapper head is in position to receive a package from the secondary folding slot, as shown in Fig. 3.

. When the package is delivered to the pocket its front edge engages the floating plateand pushes the same forwardly through the pocket. The movement of the plate under of the machine frame.

menace the influence of a following package also serves to push a preceding package ahead of the same out of the secondary wrapper head into the tertiary folding slot 130 arranged horizontally inline with the pocket. hen the packages are forced into the pocket of the secondary wrapper head they strike the outer Wrappers b and fold one side or margin about one side of the pack age. Thereafter the wrapper head is turned a partial rotation, in the direction indicated by thearrow in Fig. 14, to bring the end of the pocket which has just received a package adjacent to the tertiary folding from the pocket into the tertiary folding slot the said trailing margin of the wrapper is folded flat against the under side of the package to complete the folding of the outer wrapper. After the secondary. wrapper head has been given the one-half rotation in position to direct a partially wrapped package into the tertiary folding slot, the trailing edge or margin of the wrapper is brought to lie against a rearwardly 'facingi pasting surface 134 on an upstanding part 135 of a bracket 136 which projects laterally from and is carried by the webl21, as most clearly shown in Fig. 6. At this point the paste is applied to the forward surface of the wrapper margin, which constitutes, when the margin is folded against the package, its inner face, so that when the trailing margin of the wrapperis folded up against the package, the paste applied thereto causes the margin to adhere-to the-opposite or first foldingmargin-of the wrapper. I have herein shown a novelmechanism for applying the paste to the wrapper, which is made as follows: 1

137- designates a short shaft which ex"- tends from front to rear of the machine and is mounted at one end in the bracket 136 and at its other end in a bracket or bearing 138 Mounted on the front end of said shaft 137, in front of'the bracket 136, is a collar 140. Extending through said'collar and through the shaft is a rod 141, said rod extending beyond said collar to constitute a bearing for an axially apertured paste applying arm 142. Thesaid rod 141 is headed at its upper end to engage the outer end of the paste applying arm to hold it thereon, and is detachably' fixed in the collar 140 so that it may be endwise removed therefrom to'permit the re-' moval of the paste applying arm. Asherein shown, this attachment is efiected by means of a screw 145 which is screw-threaded'in the collar and engages at its inner end an annular socket in the rod 141. The said paste applying finger is provided at its outer or upper end with apaste applying projection 146 which is adapted to be swung past the pasting face 134 in contact with the margin of the wrapper lying against said face. The said paste applying finger 142 is provided at its inner end with a miter gear 150 which meshes with a fixed beveled annular rack 151 formed on the face of the bracket 136. With this construction, whenthe shaft 137 is rotated it serves, by reason of its connection with the paste applying finger, through the rod 141, to revolve said pasting finger about the axis of said shaft; the engagement of said gear on the paste applying finger with the annular rack 151 causes the said finger to simultaneously rotate about its own axis. The paste applying projection of said I finger is brought into contact with a paste bearing surface in onepart of its revolution to receive paste. and in anotherv part of its revolution is brought into contact with the wrapper (Fig. 3) so as to transfer the paste to the wrapper. From the construction described, it will be seen that the paste applying projection hasa rolling contact with the paste applying surface and ,the wrapper, as distinguished from the wiping contact. This construction possesses the important advantage of avoiding any tendency of the paste applying finger to shift or displace the wrapper when transferring the. paste thereto, such as would occur if the paste applying finger passed with a wiping contact across the face of the wrapper.

.The path of the projection of the paste applying finger'across the wrapper is. a

curved or arcuate path (Fig. 6). In order to avoid applying paste to the pasting face when no wrapper is present, I may provide said pasting face with a recess or depression 154 parallel to the path of the paste applying'projection ofisaid finger.

The means for transferring the paste to the paste applying finger comprises a rotative disk 156 located beneath the shaft 137 and having one face substantially in the lane ofthe pasting face. Said disk rotates in a body of fluid-paste contained in a paste pot 157, and is mounted to rotate on a shaft 158 which has suitable bearing in the wall of. the paste pot. The upper wall of-the paste pot is provided with an opening throughwhich the disk extends, and is pro-' vided also at one side of saidopening with a guard or hood 160 having a curved lip 161 Y which partiallffoverlaps the periphery of the dislc Sai 'f tjop wall is hinged at 163 to one side Wallof the paste pot so that the same may be swung upwardly-to charge the.

paste pot, and the swinging wall is locked in position by means of a swinging or hinged Said cam is provided with an external cam groove 221, and the slide 210 is provided with a downwardly projecting lug having a bearing roller 222 to engage into said cam groove. The said cam groove 221 is provided with a short straight portion 223 at one .part, (Fig. 16) which is thepart in which the lug lies .when the feed finger is in its forward position, so as to give to the finger and its slide a pause or dwell in this position. The groove may be formed with a like straight portion at the opposite side of the cam to givethe finger a slight pause in its rearmost position and thereby give time for the finger to rise into engagement with the package. The cam groove is so shaped as .to quickly advance the feed finger and retract it rapidly during the time the secondary wrapper head is passing through the portion indicated in Fig. 14.

In order to smooth or iron the ends of the package as they are forced into the tertiary folding slot, I may provide spring pressed members 226, 226 which are pivoted to the bars 195, at 227 with their forward ends extending slightly into the sides of the re-- ceiving end of the tertiary folding slot. The ends of the presser members are grooved to receive the ends ofthe package, as indicated in dotted lines inFig. 5 in full lines in Figs. 14 and. 15. The inner edges of the forward ends of the'said presser members are curved so as to flare away from each other and thereby facilitate the entrance of the package between them. The said presser members are held yieldingly in their innermost positions by springs 230, 230 that surround screw-threaded rods 231, 231 which extend through the presser members and into the bars 195, the springs being interposed between the presser members and the heads of said screws. The inward movemenaof said presser members is limited by engagement thereof with the bars 195, or otherwise. Said presser members are prop I: a i v vlded with lateral extensions or finger pieces 233, 233 by which they may be manipulated.

The completely wrapped packages arevdischarged from the end of the tertiary folding slot into and through an upwardly curved chute 235 of channel cross section suitably fixed to the machine frame and extending at its lower, receiving end adjacent to the level of the said slot. At the lower or receiving end of the chute and at the delivery end of the tertiary folding slot is located a rotative screw wheel or disk 236 which is carried by the upper end of the vertical shaft 184, before referred to (Figs.

turns in the direction indicated by the archute by hand or otherwise discharged therefrom.

The upper wall plate of the secondary folding slot is removably supported on the lower plate or parts thereof, and is held pressed onto its seat by means of a spring 'held, bifurcated presser member 240 which bears on a transverse member 241 fixed to the upper wall plate. Said presser member 240 is swingingly mounted. on a shaft 242 which extends laterally from a bearing 243 carried by the adjacent frame web 21. The

- said presser -member is normally pressed against said upper wall plate by means of a spring 245 (Fig. 3) attached to the frame and to a tail 246 of the presser member. The downward movement of said presser member is limited, when the top wall plate is re: moved, by means of a stop 248, attached to the shaft 242 on the side of the web 21 re mote from the presser member, said stop being adapted to engage a transverse. web 249, or other fixed part of the frame. The shaft is provided at its other end with a handlever 250 by which it may be manipulated to raise the presser member from the wall plate. The transverse member 241 is provided with a laterally extending hand piece 252 by which to remove the said top plate of the secondary folding slot, when the presser member is released.

Any suitable means may be employed for driving the shafts of various mechanisms, herein described. The primary and secondary wrapper heads are rotated in unison v at the same speed, and are shown in Fig. 1
