RICHARD A. BERGER, OF NEW YORIQN, Y., ASSIGNOR OF ONE-HALF TO WESLEY S. BLOCK, OF SAME PLACE.

PACKAGE-WRAPPING MACHINE SPEGIFIGATION forming part of Letters Patent No. 643,621, dated February 20, 1906.

Application filed June 8, 1899. Serial No. 719,783. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD A. BERGER, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented new and useful Improvements in Package-Wrapping Machines, of which the following is a specification.

This invention relates to that class of package-wrapping machines which are designed to apply wrapping material to articles of merchandise, particularly that type of machine wherein each wrapper or wrapper-section has its end portions-folded or tucked in upon the article and over which end portions the wrapper is next folded longitudinally from the two opposite sides of the wrapper consecutively in such manner as to completely inclose the article and protect it from the injurious efiects of air and moisture.

The machine that is the subject of the present invention is intended specially for applying wrapping material to blocks or sticks of chewing-gumin one or more layers; but I wish it clearly understood that the invention is capable of being practicably and successfully used for applying wrapping material to various articles of merchandise-such as soap cakes, chocolate, and the likein such manner that the articles will be completely in closed by folding the wrapping material around the same and tucking in the end por- "tions and corners in such a way that every part of the article will be completely covered.

The chief object of my present invention is to provide novel means whereby the article to be inclosed within a wrapper is under perfect control of parts of the machine and cannot be displaced or shifted relatively to the wrapper from the time it is placed in proper relation to the latter and is completely inclosed thereby.

The invention also has for its object to provide new and improved means for placing the wrapping material above the article to be inclosed therein and subsequently reversing the position of the article and the wrapping material, so that the article is then above the wrapping materiahand in which position the wrapping material is acted upon by folding devices for folding the same to effectually inclose the article and protect it from the effects of the atmosphere.

The invention also has for its object to provide a new and improved package-wrapping machine wherein the wrapping material is drawn longitudinally, the article of merchandise to be inclosed by the wrapping material is positioned under the wrapping material, a section of the wrapping material is severed by cutting devices, and the article and the Wrapper are then carried to and placed in a folding box or chamber with the article uppermost, wherein the folding devices fold the wrapper to entirely inclose the article. I The invention also has for its object to provide a package-wrapping machine with wrapping material in the form of a web or webs wound on reels and with novel means for drawing the webs longitudinally the proper distance at regular intervals and place the wrapping material over the articles which are to be inclosed within Wrappers severed from the web or webs at regular intervals and which wrapping material is preferably combined with a binder that has been previously cut to the required shape and provided with adhesive material along one margin.

The invention also has for its object to provide a package-wrapping machine wherein the wrapping material proper is in the form of a web wound upon a reel, and the binder is preferably in the form of a piece of paper or other suitable material that is supplied to the machine in an already cut condition, but of less length than the wrapper proper to enable the ends of the wrapper to be properly folded and the binder to be applied around the article at the proper point to bind the article and wrapper in position.

The invention also has for its object to provide new and improved means for grasping and firmly holding the article and the wrapping material and binder while they are transmitted to the folding devices, in which the article is effectually prevented from being displaced relatively to the wrapper and the latter is properly folded to inclose the article.

The invention also has for its object to provide a package-wrapping machine with new and improved end-folding and longitudinallyfolding devices for folding in end portions of to be inclosed.

tion to be severed therefrom and to lie in a position above the article which is to be inclosed within the wrapper and its binder by folding devices.

The invention also has for its object to provide a new and improved package-wrapping machine by which chewing-gum and other articles of merchandise can be completely inclosed within wrapping material composed of waxed paper or waxed paper and tin-foil, about which a binder containing any desired advertising or printed matter is applied to secure the parts and obtain a neat, symmetrical, and secure package, whereby the necessity of manually wrapping such articles as chewing-gum is avoided and the packages of chewing-gum and like materials can be rapidly produced, whichwill present a nice appearance, as though wrapped and secured by hand.

The invention also has for its object to provide nipper mechanism by which it is possible to pull wrapping material in the form of one or more webs and a binder over the articles which are to be inclosed within wrappers, the nipper mechanism having varying ranges of movement for the purpose of adjusting the binder relatively to the part of the wrapping material that is to be folded in at its ends to entirely inclose the articles.

The invention also has for its object to provide a package-wrapping machine with wrapping material in the form of one or more webs and a binder that is to be supplied with adhesive along one edge, and novel mechanism for supplying the adhesive to the edge of the hinder or for moistening the adhesive that has been previously supplied thereto, so that when the article is subjected to the action of the folding mechanism the moistened adhesive edge of the binder is securely sealed and a perfect package is produced.

The invention also has for its object to provide a new and improved feed mechanism for advancing the wrapping material to place the leading edges of its several parts in position to be seized by nipping mechanism whereby the wrapping material is drawn longitudinally in proper relation to the article that is The invention also has for its object to provide a novel arrangement of wrapper-holding reels and drawing-01f mechanism in a package-wrapping machine.

The invention also has for a further object to provide a novel suction mechanism for turning downward the leading edge of an undermost wrapper in a stack of binders that are supplied to the machine in an already-cut condition.

The invention has for a further object to provide novel mechanism for actuating the shear-blades that cut the web of wrapping material at the required point for providing a wrapper of the desired length relatively to the length of the article and the binder and for holding down the web of wrapping material while it is being severed and until it is necessary to again feed the wrapping material forward.

The invention has for a further object to provide novel mechanism for operating the nipper devices that draw the wrapping material and binder into. position above the article to be wrapped.

The invention has for a further object to provide novel devices for feeding the article to be wrapped underneath the wrapping material.

It is a further object of the invention to provide a novel mechanism for gripping the article audits wrapping material and transferring it to suitable folding mechanism.

It is a further object of the invention to provide an improved folding-box and accompanying folding mechanism for tucking in the ends of the wrapping material and for longitudinally folding the wrapper and binder around the article and sealing the completed package.

It is another object of the invention to provide improved mechanism for consecutively conveying the completed packages from the folding mechanism and delivering them to carrier devices, by which they are discharged into a suitable receptacle.

The invention also has for its object to generally improve package-wrapping machines and to provide a machine of this character which will practically and successfully apply wrappers to articles of merchandise and fold in the ends and longitudinal portions of said wrappers in such manner as to entirely inclose the articles.

To accomplish these objects my invention involves the features of construction, the combinations or arrangements of parts, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which-- Figure 1 is a top plan View of my improved package-wrappin g machine, omitting the reel which carries the web of wrapping material and with some portions of the machine broken away.

In a package-wrapping machine of the general character herein described the articles 5 of merchandise to be wrapped-such as cakes of soap or piecesof chewing-gum, chocolate, or the like, in the form of blocks, sticks, or cakes-are stored in amagazine composed of vertically-channeled standards, (designated by the reference-numeral 1 in Figs. 1, 2, and 3.) These vertically-channeled standards 1 are erected a suitable distance apart and may have any desired height to' receive and accommodate any quantity of articles (desighated by the numeral 2, Fig. 2) that are superimposed one above another in a vertical column or stack. The channeled opposing faces of the standards 1 serve to receive the ends of the articles, so as to retain said artino cles in a column or stack and guide them in a downward direction for discharge from the magazine. At their lower open ends the standards 1 may be braced by arecessed and shouldered plate 3, through which they are I15 secured to a table 4, that is supported at a suitable point on the frame of the packagewrapping machine.

Beneath the table 4 there are guides 5, Fig.

3, for a feed-slide 6, Fig. 15, which is mov- 12o able forward and back for successively discharging the articles 2 from the magazine. This feed-slide 6 is provided at its front end with forwardly-projecting arms 7, having upturned flanges 8, the construction being such :25

that when the feed-slide 6 is moved rearward.-, and its arms 7 lie directly under the lower open end of the magazine, as shown in Figs. 1 and 3, a single article-as, for instance, a block of chewing-gum-will fall by gravity :30 upon said arms and lie between the front edge of the feed-slide and the upturned flanges 8 of the arms 7, so that if the feed-slide 6 be advanced or moved forward the article supported by said arms 7 will also be carried for ward and the solid portion of the feed-slide will move under the column or stack of articles and support the same until the article carried by the arms 7 is removed therefrom and the feed-slide is again moved rearward to again place the arms 7 directly under the lower open end of the magazine, whereupon another article will drop onto said arms. Obviously instead of feeding the articles singly from the magazine several could be discharged at once, superposed one on another, by thickening the feed-slide 6 and making the upturned flanges 8-of a correspondingly-increased height. In this case the several blocks or cakes discharged together would be subsequently inclosed in the same wrap per. Ordinarily, however, the articles will be discharged singly and be each separately wrapped, as hereinafter described.

The wrapping material in which the articles 2 are to be inclosed may be composed of three layers-namely, first, a layer 9 of thin waxed paper; second, a layer 10 of tin-foil, and, third, a binder 11, which in practice will bear on its outer side any desired advertising matter. The layers of waxed paper and tinfoil are coequal in dimensions, but the outside binder 11 is considerably shorter than the inner layers 9 and 10,composing the wrap per proper. At one side edge the binder 11 projects beyond one longitudinal edge of the waxed paper and tin-foil, and this projecting portion 12 of the binder 11 is provided on its under side with adhesive material. During the wrapping of the package this projecting adhesive margin, being properly moistened, is cemented down upon the previouslyfolded opposite longitudinal edge portion of said binder 11 for effectually sealing the package. The several layers composing the wrapper and binder are at first applied to the upper side of the article by causing the feedslide 6 to move said article into position beneath the wrapping material, and the said article and layers of wrapping material are then gripped together and reversed in positionthat is to say, they are turned upside downso that the cake or block of merchandise is uppermost, lying above the wrapper. In effecting this reversal of position the article 2 and the superposed wrapper and binder are transferred into a folding-box 13, Figs. 3, 12, 18, 19, 21, 23, and 24:, as will hereinafter appear. It was before remarked that the wrapper proper may be composed of waxed paper 9 and tin-foil 10, superposed one on the other. These wrapping materials are preferably in the form of webs, and as a means for carrying said webs of wrapping material any suitable reel or reels may be provided, as hereinafter described. In some cases, however, the web of tin-foil may be dispensed with, and, as generally illustrated in the drawings, I have shown the wrapper proper as composed only of waxed paper 9, with which a binder or label 11 is combined. The foldingbox 13 and coacting devices are so constructed, as hereinafter described, that as the article and its now underlying wrapper are pushed down into said folding-box the edge portions of the wrapper and binder are forced upward into a perpendicular position, as shown in Fig. 20, after which the end portions of the Wrapper are tucked in, as shown in Figs. 21 and 22. One longitudinal side of the wrapper, together with a corresponding portion of its binder, is then folded and pressed downward upon the article, and subsequently the opposite side is folded down, as indicated in Fig. 23, and the adhesive margin 12 is finally pressed down so as to cement the overlapping parts of the binder, thus producing the completely wrapped and sealed package, as shown in Fig. 26, wherein the article of merchandise is securelyinclosed and protected from atmospheric influences. It will be observed that in the completed package the binder 11 has a length that does not exceed the length of the wrapped article, and it is for this purpose that said binder is made of a length considerably less than the length of the layer or layers composing the wrapper proper. As the wrapper and binder are drawn into position in front of the magazine the feed-slide 6 at the lower open end of the magazine is moved forward and the article lying 011 the arms 7, between the front edge of said feed-slide and the upturned flanges 8, will be carried forward and placed beneath the wrapper, so that, the said wrapper actually lies above the article. The wrapper proper having been severed from its web and brought into properly-adj usted position with relation to the article and binder, the said article, wrapping material, and binder will be next transferred into the folding-box 13 by aswinging movement imparted through the medium of two gripping and transferring jaws 14c and 15, Figs. 3, 4:, 5, 6, and 17, that are carried by swinging yoke-frames 16 and 17, respectively. As clearlyshown in Fig. 17, the gripping-jaw 14 is made sectional to pass by the arms 7 of the feed-slide 6, Fig. 15, while the jaw 15 may be in the form of a solid bar or plate. The yoke-frame 16 of the sectional gripping-jaw 14 is formed with a sleeve 18, through which said yoke-frame is secured, by means of a key 19, Figs. 3 and 17, to a shaft 20, that is journaled in suitable hearings on the machine-frame and arranged about midway between the folding-box 13 and the point where the article of merchandise was fed to the under side of the wrapping material. To one end of this shaft there is secured a pinion 21, Figs. 1 and 17, which engages a segmental rack 22, Figs. 1, 2, 3, and 13. The yoke-frame 17 of the solid grippingjaW 15 is loosely mounted on the shaft 20 outside the yoke-frame 16 by means of sleeves 23, Fig. 17, on one of which there is formed or secured a pinion 2 1, meshing with a segmental rack 25, Figs. 1, 2, 3, and 13, both racks 22 and 25 having a pivoted support on a what may be called the 1 normal or open longitudinally-arranged shaft 26, as shown. The segmental racks 22and 25 are independently operated, as will hereinafter appear, and they swing back and forth in a direction from front to'rear of the machine. In

position of the gripping-jaws 14 and 15 (indicated by full lines in Figs. 1 and 3) the sectional jaw 14 lies toward and slightly below the level of the arms 7 on the feed-slide 6, and therefore when an article is discharged from the magazine as the wrapping material is drawn longitudinally into a position in front of said magazine the article is pushed under the wrapping material and is carried directly-above the sectional jaw 14 in readiness to be gripped. During this operation the other gripping-jaw 15 lies in the folding-box 13, and after the article and wrapper are brought into correct position above the jaw 14 the yoke-frame 17 is swung in the are of a circle and its jaw 15 leaves the foldingbox and cooperates with the jaw 14 to firmly grip and hold the article and its wrapper, after which the two jaws, gripping said article and wrapper, swing forward in unison in the arc of a circle, as indicated by dotted lines in Fig. 3, and the jaw 15 again enters the foldingbox 13 and descends therein, so that the article and wrapper are now reversed in position and the article will lie above the wrapper instead of under the same, as when it was first gripped by the two jaws. The sectional jaw 14 will then move back independent of the jaw 15 to the posit-ion shown in full lines,

Fig. 3, in readiness to take another article from the arms 7 of the feed-slide.

As shown, the wrapperproper is preferably employed in the form of a continuous web, as indicated by 9, Figs. 4, 5, and 6, from which sections of suitable length are severed by means of shear cutter-blades 27 and 28, operated at properly-timed intervals; but the binders 11 are preferably supplied to the machine in an already-cut condition and of a length and width corresponding to the dimensions of the article to be wrapped and sealed.

For the purpose of storing the binders 11 in the machine in readiness for immediate use there is provided a hopper 29, Figs. 1, 2, and 4, which is constructed with two parallel vertical walls arranged longitudinally of the machine and havinginwardly turned flanges 30, that are inclined from the perpendicular in such manner that the pile or stack of binder-blanks stored in said hopper will occupy a staggered position, as shown in Fig. 4. The bottom of the hopper 29 consists of a plate 31, having a hinged downwardly-swinging leaf 32 at the point where the binders 11 are to be successively discharged. This hopper 29 and its bottom plate 31 are supported on a table or plate 33 in such manner as to provide beneath the hopper a sufficient space for passage of the wrapper-web 9, from which the wrapper proper is to be severed by the cuttenblades 27 28 at the proper time. The hinged downwardly-swinging leaf 32 of the hopper-bottom is made hollow and provided in its upper face with a series of air-inlet holes 34, Figs. 1, 10, and 11, which are directly under the leading portion of the lowermost binder or label 11 in the hopper 29, so that by inducing a suction in the said hollow hinged leaf 32, at the same time swinging said leaf downward, the leading edge of the lowermost binder will be readily drawn or sucked away from the next binder above and be thus brought into position to be conveniently grasped by nipper-j aws,hereinafter described, at the same time that other nipper-jaws are made to grasp the leading edge of the wrapper-web 9 which is immediately below. Thus the hollow downwardly-swinging hinged leaf 32 constitutes, in effect, a pneumatic suctionnozzle for separating the lowermost binder or label from those piled above in the hopper 29, and by imparting a positive downward swinging movement to this hinged hollow leaf or nozzle at thesame time that suction is in duced therein the operation of separatingthe binders or labelsll singly and successively from the bottom of the pile will be accomplished with ease and certainty. It will be observed by reference to Figs. 4, 9, 10, and 11 that the leaf 32 istapered in transverse section and that its thickest portion is next to the plate 31, to which it is hinged in a line that coincides with the top edge of each of these parts, hinge-lugs 35 being arranged on the plate 31 and leaf 32 in such position that the pivotal axis of said leaf in its upper edge will be in line with the upper edge of the plate 31, which constitutes the bottom of the hopper. By this manner of hinging the nozzle-leaf 32 its downward swing will leave no gap between it and the edge of the plate 31 into which a label or binder 11 might be drawn. The hinged portion of the leaf 32 is beveled oif at 36, Figs. 10 and 11, and a corresponding bevel is provided on the edge of the plate 31 to afford ample clearance for the required downward swing of the leaf 32 at proper intervals. When the hinged leaf or nozzle 32 is in a raised position, its upper surface is substantially flush with the top of the plate 31, as in Fig. 9; but when the said leaf is swung down its top presents an incline to which the leading portion of a superposed binder or label 11 is drawn by suction and over which the label or binder may be readily withdrawn for its intended use. Oneend of the hinged leaf or suction-nozzle 32 is provided with a nipple 37 for attachment of a rubber tube 38, which connects with a suction air-pu mp 39, Figs. 1 and 2, through which suction is induced in said hinged leaf or nozzle at proper intervals. In the cylinder of the pump 39 there is a spring 40, Fig. 2, for forcing out a plunger 41, thereby causing suction in the hinged leaf or nozzle 32 for the purpose already explained. The plunger 41 is connected by a link 42 to one end of a twotoo IIO

armed lever 43, that is pivoted to the machine-frame and operated at intervals to compress the spring 40, as hereinafter explained. For the purpose of swinging the hinged leaf or suction-nozzle 32 there is provided a lever 44, Figs. 1, 2, and 9, one end of which is bifurcated to engage the nipple 37 on one end of said leaf or suction-nozzle. The other end of this lever 44 is secured to a rock-shaft 45, that is operated through mechanism hereinafter described. By reference to Figs. 1 and 4 it'will be observed that the lower edge of one of the inclined flanges 30 on the hopper 29 is formed with an everted lip 46, that is designed to positively direct one side edge of each binder or label 11 toward a gum ming or moistening disk 47 for the purpose of applying adhesive to the projecting margin 12 of said binder or label as it is withdrawn from the hopper 29 or for moistenin g adhesive material that may have been applied to the binders or labels before stacking them in the hopper. The gumming or moistening disk 47 is supplied through feed-disks 48 and 49 from a pan 50, Figs. 2 and 4, which may contain any suitable gumming or moistening liquid. The required rotation of the disks 47, 48, and 49 is effected through gearing that will be hereinafter described. In order to permit ready access of the nipper-jaws, pres-- mechanism by which the web or webs of wrapping material and the binder or label are drawn or pulled longitudinally into required position in front of the magazine and over the article to be Wrapped.

There are two pairs of nippers that are each composed of fiXed jaws 53 54 and movable jaws 55 56, Figs. 4 and 16. The fixed jaws 53 and 54 are rigid with the inner ends of horizontally-movable slides 57 58, that are guided in dovetail grooves on opposite sides of a fixed plate 59, forming an extension of the machineframe. One movable nipper-jaw 55 is pivoted, as at 60, to the inner end portion of the slide 57 and is articulated at one side of its pivot to one extremity of a lever 61, that is also pivoted or fulcrumed on said slide.

The outer ends of the levers 61 and 62 are provided with roller-studs 63, adapt-ed to travel in longitudinal gnideways 64 in opposite sides The movable jaw 56 of the other nippers may form of a bar 65, that is adapted to belifted and lowered for actuating the levers 61 and 62 in such manner as to close and open the nipperjaws, as required. On each slide 57 and 58 there is a stud 66, Fig. 16, for pivotal attachment of links 67, Figs. 1, 2, and 4, connecting with the upper ends of levers 68, which at their lower ends are pivoted on studs 69 in such manner that when said levers are Vibrated the slides 57 and 58 will be reciprocated, and consequently a corresponding reciprocation will be imparted to the nipper-jaws.

The vertically-movable bar 65, Figs. 1, 2, 4, and 16, is provided near its ends with depending studs or guide-pins 70, that are eX- tended downward through openings in the plate or bar 59 to connect with the ends of levers 71 and 72, that are fulcrumed at 73 and 74, respectively. At one side of their pivots these levers 71 and 72 are connected by intermeshing gear-teeth 75, as shown in Fig. 2, so that when the lever 72 is moved by oscillation of a lever-arm 76, which is rigid therewith, a corresponding movement will be imparted to the lever 71 through said gear-teeth. Between the depending pins or studs 70 and the pivots of the levers 71 72 there are arranged springs 77, Figs. 2 and 4, which bear down on said levers to cause them to draw on the pins 70, thus imparting a positive downward movement to the bar 65, whereby it acts on the levers 61 and 62 in such direction as to cause them to hold the nipper-jaws normally open. On oscillation of the lever-arm 76 in the proper direction, as hereinafter explained, the levers 71 and 72 will be made to act on the pins 70, so as to lift the bar 65, and thereby actuate the levers 61 and 62, so as to close the nipper-jaws onto the wrapping matcrial and hinder or label after said nipperjaws have been moved into position for grasping said wrapping material and binder. Thus if the bar be raised the nipper-jaws will be caused to close for the purpose of gripping the leading edges of the wrapping material and its binder to draw the same forward, and, conversely, if said bar 65 be lowered the Dipper-jaws will open and release the said wrapping material and binder or label. While the slides 57 and 58 are advancing the bar 65 is in its depressed position, and consequently the nippers are open to receive the leading ends of the Web 9 and binder or label 11, one pair of nippers being arranged to seize the end of the web -9 and the other pair to seize the binder 11, as indicated in Fig. 4, so soon as the said nippers have advanced the required distance. Just before the nippers have reached the position in which they are shown in Fig. 4 the hinged leaf or suctionnozzle 32 has been swung downward and suction has been induced therein, so as to draw down the leadingportion of the undermost binder 11 in the hopper 29, and when the nippers are farther advanced to gripping position the bar 65 will be raised and the movable nipper-jaws will thus be closed toward the i l l fixed jaws, thereby firmly grasping the wrapping material and binder. The slides 57 58 are next retract-ed, thereby drawing the wrapping material 9 and binder 11 into a position in front of the magazine and over the sectional gripping and transferring jaw 14, as shown in Fig. 5. When a sufficient quantity of the web 9 has been drawn in front of the magazine, the shear-blades 27 28 close, as shown in Fig. 5, and sever said web to produce a wrapper. Meanwhile an article2 is discharged from the magazine and carried by the feed slide-arms 7 into position above the jaw 14 and under thewrapping material, as shown in Fig. 6. In drawing the wrapperweb 9 and binder 11 in front of the magazine the nippers that pull the web 9 are caused to move somewhat more rapidly than the nippers which draw the binder 11, as indicated in Figs. 5 and 6, thereby adjusting the web 9 and binder 11 in such relative position that i the ends of the wrapper 9 will project beyond the ends of the article 2 and binder 11, while said article and binder will be coterminous. In other words, when the two pairs of nippers seize the leading ends of the web 9 and binder 11 and commence their outward strokes that pair of nippers 53 which seizes the web 9 will move slightly faster at the beginning than the pair of nippers 54 56 which seizes the binder 11, so that the web 9 is drawn ahead of the binder 11 for the purpose of obtaining a wrapper in which the inner layer or wrapper proper will be ofgreater length than the binder. After the wrapperweb 9 is severed by the shears 27 28 it continues to move ahead slightly faster than the binder 11 until the article 2, wrapper 9, and binder 11 are in properlyadjusted position.

In Fig. 6 the article 2 is represented as lying on the sectional gripping and transferring jaw 14 in readiness to be lifted away from the feed slide-arms 7, the wrapper9 and binder 11 are superposed above the article, one pair of nippers has placed the wrapper 9 in correct position relatively to the article, the other pair of nippers has drawn the binder 11 into position centrally over the wrapper 9, the shear-blades 27 28 are open, and the grippingjaw 15 is approaching the jaw 14 for the purpose of gripping the binder, wrapper, and article between the two jaws 14 15 and transferring them to the folding-box 13, as before explained. After the nippers have drawn the web 9 and hinder or label 11 longitudinally into position over the gripping-jaw 14 and the web 9 has been severed by the shear-blades 27 28 and until the nippers again advance to repeat the operation already described the portion of the web 9 which is connected with the reel should be held or pressed down in a fixed position upon the table 33 for the purpose of maintaining its leading end in accurate position to be seized by the nippers at the proper time for forming another wrapper. This holding down of the web 9 is efiected through the medium of a pressing-finger 78,

Figs. 1, 2, 4, 5, 6, 7, 27, and 28, that is extended over the web of wrapping material. The pressing-finger 78 is carried by a rockshaft 79, which is positively turned at properly-timed intervals, by means hereinafter explained, to raise and lower said finger in such manner that when the finger is lowcred, as shown in Figs. 4 and 6, it will press upon and hold the web 9, and when it is raised, as shown in Fig.5, it will release the said web and permit it to be moved longitudinally by the nippers, but will descend again as soon as the web 9 is severed. 13y reference to Fig. 7 it will be seen that the tail end of the upper shear-blade 27 has secured thereto, beyond the pivot of said blade, a stripping and supporting finger 80, which acts to strip the leading edge of the web 9 away from the lower shear-blade 27 when the cutter-blades open and to support the said leading end of the web, so that it willnot curl downward. There is a notch 81 in the upper edge of this finger 80 to permit access of the nipper-jaws that pull the wrapper-web. As shown in Fig. 1, a flat guide-finger 82 is preferably extended in a longitudinal direction part way in front of the magazine for the purpose of supporting that edge portion of the wrapper which is nearest the magazine, so that the article discharged from the magazine can be readily fed to its required position beneath the wrapper without striking against and bending or curling the wrapper edge. As soon as the nipper-jaws 53 55 and 54 56 have properly adjusted the wrapper 9 and binder 11 above the article 2, said jaws will have been retracted a sufficient distance to permit gripping of the article and wrapper by descent thereon of the gripping and transfer ring jaw 15, whereupon the bar will be depressed to open the nipper-jaws and release the wrapper and the binder or label. There is a pause in the retractile movement of the nippers just before the article and wrapper are grasped by the gripping and transferring jaws 14 15. Then the nipper-jaws open and the retractile movement of the nippers continues, the nipper-jaws 54 56 now moving faster than the jaws 53 55 until both pairs of nippers are in alinement and returned to their full retracted position, in which both pairs of nipper-jaws remain open in readiness for further operation. The nipper-jaws that grasp the binder 11 do not at any time come into the path of the swinging gripperjaw 15, and the nipper-jaws that pull the wrapper 9 are always out of the way before the jaws 14 and 15 grasp the article and its wrapping material. The article to be wrapped being firmly gripped together with the wrapping material and binder or label by the gripping and transferring jaws 14 and 15, as already described, these jaws now conjointly swing in the arc of a circle, as indicated by dotted lines in Fig. 3 and in the direction of the arrow there shown, thereby depositing the article, wrapping material, and

binder into the folding-box 13 in readiness for the operations of making the necessary folds in wrapping and sealing the package. The jaw 15 remains in the folding-box during the folding operation and the removal of the wrapped and sealed package, while the jaw 14 is quickly swung back to normal position in front of the magazine for subsequent transfer of an article and its wrapper and binder.

The folding-box and accompanying folders are particularly designed to so fold the wrapper 9 and binder 11 that the end portions of the inner layer or wrapper 9 will be creased, folded, and overlapped or tuckedin beneath the longitudinal folds of both the inner layer 9 and outer layer or binder 11 to secure aperfectly-wrapped package covered and protected at every point, corners and all, thereby effectually excluding air and moisture from the wrapped article.

As clearly shown in Fig. 18, the folding-box 13 has the form of an opentop rectangular receptacle comprising a front wall 83, a rear wall 84, and end walls85, with slots or openings in each. The end walls are provided with horizontal slots 86 for passage of laterally-movable end-folders 87, Figs. 12, 19, and 21, and the front wall 83 has a horizontal slot 88 for passage of the front longitudinal folder 89, Figs. 3, 23, and 24. The rear wall 84,

Fig. 18, is of less height than the front and end walls and is formed with a central cut away portion 90, having slotted end extensions 91 for passage of the rear longitudinal folder 92 and elastic roller 93, Figs. 3, 12, 23, and 24, the ends of the plate portion of said folder 92 being permitted to pass at the slotted openings 91, while the roller 93 on the edge of said plate will roll over the wall 84 and onto the article in the folding-box. The rear wall and the bottom of the box are provided with vertically-extended slots 94, Fig. 18, to accommodate the side arms of the yokeframe 17, by which the gripper-jaw 15 is carried. The four corners of the box are formed or provided with vertical finger-like extensions 95, having blunt upper extensions and approximately rectangular inner surfaces, as shown in Fig. 18. It is preferable to have the two vertical extensions 95 at the rear of the box of less height than the front ones, as shown, and the top edges of the end walls of the box are inclined downward from front to rear between said front and rear vertical extensions. On the frame of the machine at the ends of the folding-box 13 there are four diverging wings 96, Figs. 1 and 7, the top edges of which are inclined upwardly and outwardly from the several vertical extensions 95 at the corners of the box, as shown. Now as the article and its wrapper are carried over to the folding-box in a path that describes the arc of a circle the projecting portions of the wrapper 9 will be first presented flatwise to the said wings 96, that diverge outwardly and upwardly from the vershown.

tical finger-like extensions 95 at the corners of the box, and as the two gripping and transferring jaws 14 and 15 force the article 2, wrapper 9, and binder 11 into the folding-box 13 these wings 96 will gradually turn the projecting portions of the wrapper 9 upward along diagonal lines diverging from the corners of the box, and thus as acted on by the diverging wings 9b and vertical finger-like extensions 95 the corner portions of the wrapper 9 will first buckle or crimp and turn upward or inward, and then the inside corners and walls of the box 13 will turn the ends and longitudinal edge portions of the wrapper 9 upward, together with the longitudinal edge portions of the binder 11, in such manner that the form or shape of the wrapper and binder will become approximately or substantially as shown in Fig. 20. The endfolder blades 87 are now caused to advance and enter the slots 86 of the end walls of the box 13 to fold end portions of the wrapper 9 down upon the article, as shown in Figs. 21 and 22, whereby portions of the buckled or crimped wrapper-corners will overlap, as The end-folders 87 next retreat, and then the front longitudinal folder 89 is caused to enter the box 13 through the slot 88 and fold one longitudinal edge portion of the wrapper 9 and binder 11 over onto the article 2, as shown in Fig. 23. As the folder 89 retreats the rear longitudinal folder 92 advances and carries its roller 93 into the folding-box and over the article therein, so as to fold down the rear longitudinal edge portions of the wrapper and binder, as shown in Figs. 3, 12, and 23, thereby pressing down and securing that edge of the binder 11 which is supplied with adhesive. The completelywrapped and securely-sealed package now presents the appearance shown in Fig. 26. By first buckling or crimping and turning inward the cornerportions of the inner wrapper 9, as in Figs. 19 to 22, and subsequently folding in the ends and then the longitudinal side portions, as above described, the corners of the article, as well as all other parts thereof, are perfectly covered and protected to effectually prevent access of air or moisture. After the package is wrapped and sealed in the folding-box 13, as above described, and before the rear longitudinal folder 92 and attached roller 93 recede a sweeper-bar 97, Figs. 1, 3, 12, 23, 24, and 25, is carried rearward over the said folder 92 and roller 93, and then this folder and roller retreat. Now while the sweeper-bar 97 remains stationaryin its rearward position the gripping-jaw 15, lying'in the box 13, rises and then pauses, thus bringing the wrapped package up in front of sweeper-lugs 98, Figs.

2 and 24, on the under side of said sweeperbar. The sweeper-bar 97 then advances toward thefront of the machine,thereby drawing the completed package off from the grippingjaw 15, as shown in Fig. 24, and onto a table 99, over which it is further drawn by said Sweeper 97 t and beneath an elastic roller 100, where it is temporarily deposited until after the wrapping operation has been repeated on a succeeding article. The sweeper 97 then travels back and carries the lastwrapped article onto the table 99 and against the preceding package, so as to push the latter out from beneath the roller 100, and so on. In passing under this elastic roller 100 the package is subjected to a pressure that is just sufficient to make certain the secure sealing of the wrapper without subjecting the inclosed article to any injury.

The sweeper-bar 97 is attached to or formed on arms 101, thatare pivoted or trunnioned to lugs 102 on slide-arms 103, Figs. 3 and 25,

connected by a cross bar or bars 104 and supported in suitable guides beneath the table 99, on which the completed packages are first deposited. A spring 105, Figs. l,"7, and 25,

is connected with one of the arms 101 in such" manner as to hold the sweeper 97 down to its work.

The elastic pressure-roller 100 has a shaft 106, that is jonrnaled in bearings 107 on the machine-frame, and on this roller-shaft 106 are loosely mounted the arms 108 of a gravity presser-bar 109, Figs. 1 and 23, under which the completed packages are successively pushed. By means of this presser-bar 109 the completed packages are directed in succession into engagement with hooked projec tions 110 on the peripheral portions of a pair of carriers 111, Figs. 23 and 25, by which the said packages are successively deposited in edgewise position in or upon an elongated tray or trough 112, Figs. 23 and 25, for ultimate removal from the machine. The carriers 111 are preferablyin the form of plates secured to a rotatable shaft 113, mounted in the sides of the tray or trough 112 at its junction with the main frame of the machine, and, as shown in Figs. 23 and 25, the rear end of the tray-bottom and the overhanging front edge of the table 99 are each suitably cut away for passage of the rotatable carrierplates 111 and for convenient reception of the wrapped packages thereon. One of the carrier-plates 111 is provided with a number of laterally-projecting pins 114 to be successively pushed against by a pawl 115 on the cross-bar 104 of the slide-arms 103, by which the sweeper 97 is carried. The number of these pins 114 corresponds with the number of hooked projections 110 on each of the carriers 111, so that as each pin is pushed against by the pawl 115 the carriers will be thereby rotated a sufficient distance to receive a package from under the presser-bar 109, pushed along by the succeeding packages, and also to nearly or quite deposit a package in the tray 112, as shown in Fig. 23. A spring-detent 116 is provided on the tray or trough 112 to engage each pin 114 in such direction as to prevent backlash or reverse rotation of the carrier 111 when the sweeper 97 returns toward the folding-box. The periphery of each carrier 111 is provided with a series of flattened surfaces 117, that are each extended from the inner side of one hooked projection 110 to the outer side of the next hooked projection, the several hooked projections being turned rearward, as shown in Fig. 23. These flattened surfaces 117 receive the packages as pushed along successively from beneath the presser-bar 109, one package on the corresponding flattened surfaces of the two parallel carriers and each resting against corresponding hooked projections of said carriers. Consequently as the two carriers are rotated together step by step by the pawl 115 the packages will be deposited consecutively in or upon the tray or trough 112, as before stated. A guard 118, Fig. 25, is provided on the inner end of the tray 112 to prevent the deposited packages from falling over toward the shaft 113, to which the carriers 111 are secured. The completed packages are deposited edgewise, and for the purpose of maintaining them in this position a bar 119 is slidingly supported across the tray 112 for the forward package to bear against as the accumulated packages are advanced along the receiving tray or trough. One end of this bar or'sliding support 119 rests loosely upon the top of one side edge of the tray or trough 112, and the other end of said bar or support is slidingly hinged or pivoted on a rod 120, Fig. 25, supported along the opposite side of the tray, so that the bar 119 can slide along the tray as pushed forward by the accumulating line of packages or may be swung to one side when so desired. As the receiving tray or trough 112 becomes filled the packages can be removed and the slide or bar 119 be moved back toward the package-carriers.

It will now be convenient to proceed with description of the mechanism for actuating the several working parts of the machine that are immediately concerned in the wrapping of such articles as chewingum, chocolate, or the like and for discharging the completelywrapped packages from the wrapper folding and sealing devices already described.

At one end of the machine-frame there is a drive-shaft 121, mounted in suitable bearings and carrying a pinion 122, Fig. 2, meshing with a large spur-gear 123, Figs. 1, 2, and 3, on a counter-shaft 124, which transmits power through bevel-gearing 125 to a lineshaft 126, supported in suitable bearings along the front of the machine. 126 connects through bevel-gearing 127 with a shaft 128, having its bearings on the righthand end of the machine-frame, as shown in Fig. 1. The drive-shaft 121 may be provided with driving and clutch devices of any suitable character controlled through a lever 129, as may be required.

By reference to Figs. 1, 2, and 3 it will be seen that the rear end of the shaft 124 car- IIO The shaft ries a cam 130, the periphery of which is formed to act in such manner on aroller 131, Fig. 3, attached to the lever 43, Fig. 2, as to cause said lever to lift the air-pump plunger 41 against the action of the spring 40 and hold said plunger elevated until the open nipper-jaws 53 55 and 54 56 have nearly approached the point where they are to seize the wrapping material and its binder. A releasing portion 132 of the cam 130 then passes by the roller 131, and thus permits the lever 43 to yield under the strain exerted by the compressed spring 40, that now forces the pumpplunger 41 outward and so induces suction in the hinged nozzle 32, Figs. 1 and 4, which is immediately thrown downward by its lever 44, Figs. 1, 2, and 9, into the position shown in Fig. 4, and thus the lowermost binder 11 in the hopper 29 has its leading edge sucked downward into position to be readily grasped by one pair of nipper-jaws at the instant that the leading edge of the web 9 of wrapping material is seized by the other pair of nippers. When the nippers in moving backward have drawn a binder 11 and a suflicient quantity of the wrapper-web 9 outward in front of the magazine, as before explained, the shear-blades 27 and 28 close forcibly and sever the web 9 at the required point to give the necessary length of wrapper. The shearblades 27 and 28 are pivotally mounted on a common axis 133, Fig. 7. The upper shearblade 27 is constructed with a rearward-extended tailpiece 134, which is connected by a link 135 with one arm of a bell-crank 136, Figs. 2 and 8, fixed on a rock-shaft 137, that is suitably mounted on the machine-frame. The lower shear-blade 28 is connected by a link 138 with a crank-arm 139, that is also fixed to said rock-shaft. The upwardly-projecting arm of the bell-crank 136 is connected by a rod 140 with the upper end of a lever 141, which is pivoted at 142 to a portion of the machine-frame. This lever 141 supports a roller 143, that is in bearing contact with the periphery of the cam 144 on the shaft 124, that is actuated from the drive-shaft, as before explained. This cam 144 is arranged to act on the roller 143 to force the lever 141 in such direction as to maintain shear-blades 27 and 28 in a normal open position. When in this position, the lever 141 is locked by a latch 145, mounted thereon and engaging a catch 146 on the machine-frame. A spring 147 normally forces the latch 145 into engagement with said catch. On the cam 144 there is a laterally-projecting pin148, which at the proper time will strike one end of the latch 145, thereby disengaging its other end from said catch 146, and at this instant the spring 149, connected with the lower end of said lever 141, will forcibly act thereon in such manner as to cause it to pull on the rod 140, and thereby vibrate the bell-crank 136 in such manner as to cause the shear-blades 27 and 28 to sever the web 9 of wrapping material. In the periphery of the cam 144 there is a cut-away portion 150, which comes opposite the roller 143 when the catch 145 is tripped,

and thereby permits the spring 149 to vibrate the shear-actuating lever.

The levers 68, through which the nippers are reciprocated, each support a roller 151, engaged in cam-races 152 and 153 on opposite sides of a large cam-wheel 154 on the shaft 124, as shown in Figs. 1, 2, and 4. The camrace 152 is formed in a thickened or offsetting portion 152 of the cam-wheel. The cam-race 153 differs slightly in contour from the camrace 152, as indicated by dotted lines in Fig. 4, the purpose being to provide for a longer travel of the roller 151, engaged in this camrace 153, whereby in retracting the nippers the jaws 54 56, that pull the binder 11, will move less rapidly than the jaws 53 55, which draw the wrapper-web. Both cam-races 152 and 153 are so constructed as to provide for the necessary pauses in the operation of the nippers to conform with the requirements of the machine. The cam-wheel 154 has an enlarged peripheral portion 155 of suitable extent for acting at the proper time against a roller 156 on the end of the bell-crank lever 76, through which the bar is lifted to close the nipper-jaws onto the Wrapping material. After the wrapping material has been drawn in front of the magazine and the nippers retracted, the bell-crank lever 76 will be released by the reduced portion of the cam-wheel 154, and then the bar 65 will be forced down by the springs 77 to open the nipper-jaws and release the wrapping material. In the meantime the feed-slide 6 has moved an article outwardly from the lower part part of the magazine and beneath the wrapping material. This feed-slide 6 is connected by a link 157 with the upper end of a lever 158, that has its lower end pivoted at 159 to a portion of the machine-frame, as shown in Fig. 3. The lever 158 is connected by a rod or bar 160 with the upper end of a vibratory lever 161, the lower end of which is pivotally supported at 162 on thelowerportion of the machine-frame. The lever 161 carries a roller 163, engaged in a cam-race 164 of a cam 165, mounted on the shaft 126, Figs. 1 and 3.

The segmental racks 22 and 25 for operating the gripping-jaws 14 and 15 are actuated through bars orlinks 166 and 167, Fig. 13, that connect, respectively, with the upper ends of vibratory levers 168 and 169, having a pivotal support 162 at their lower ends. Each of these levers 168 and 169 supports a roller 171 and 172, engaged, respectively, in cam-races 173 and 174 in opposite sides of a cam-wheel 175 on the shaft 126, and these cam-races 173 and 174 are so formed that the gripping-jaw 14 will be independently operated to carry it into position to receive the article to be wrapped and the gripping-jaw 15 will be operated independently to bring it into position above the wrapping material, after which both jaws will operate in unison in transferring the article and its wrapper into the foldingbox. As the gripping-jaw 14 returns to the 176 are connected with each other through folding-levers 177 and 178 in such manner that said bars may be moved in unison. One of said bars 176 is connected, through a link 179, with the upper end of a vibratory lever 180, having a pivotal support 181 at its lower end. This vibratory lever 180 supports a roller 182, engaged in a cam-race 183 in a camwheel 184 on the'shaft 124, as shown in Figs. 1 and 12. 1

The front longitudinal folder 89 is secured to the upper portion of a vibratory frame 185, Figs. 3 and 14, the lower end of which has a pivotal support at 186 within the machineframe. This vibratory frame 185 connects by a link 187 with the upper end of a lever 188, having the pivotal support 162 at its lower end. The lever 188 supports a roller 189, engaged in a cam-race 190 in a cam-wheel 191 on the shaft 126.

The rear longitudinal folder 92 and its attached roller 93 are carried by the upper end of a vibratory frame 192,having a pivotal support 193 at its lower end. This vibratory frame 192 connects, by a link 194, with the upper end of a lever 195 on the pivotal support 162 and supports a roller 196, engaged in a cam-race 197 in one side of the cam-wheel 165, from which also the feed-slide 6 is actuated. After the rear longitudinal folder 92 and roller 93 have completed the folding and sealing of the package the sweeper-bar 97 is moved rearward, the rear longitudinal folder retreats,and the gripper-j aw 15 lifts the package in front of the lugs 98 on the sweeperbar. The sweeper-bar 97 then moves forward and conveys the package to and beneath the elastic roller 100, as before explained. This sweeper-bar 97 and also the pawl 115, Figs. 23 and 25, which actuates the carriers 111, are operated from a cam-wheel 198 on the shaft 126, Fig. 7. In one side of this cam-whcel198 there is a cam-race 199,engaging the roller 200 on a vibratory lever 201, having a pivotal support on the shaft 162, as shown in Fig. 7. The upper end of the vibratory lever 201 is connected, through a link 202, to one of the slidearms 103, on which said sweeper-bar 97 and pawl 115 are mounted.

When the nipper mechanism draws forward the wrapper-web 9 and binder 11 in front of the magazine, the-finger 78 rises and relieves the web 9 from pressure; but as soon as the shear'blades 27 and 28 sever the web'9 this finger 78 descends and holds the web 9, so that it cannot slip back. As before stated, the pressure-finger 78 is mounted on a rock-shaft 79, Figs. 1, 2, and 7. On this rock-shaft 79 is a crank-arm 203, which is connected, through a link or rod 204, Fig. 7, with the upper end of a vibratory lever 205, that supports a roller 206, engaged in a cam-race 207 in one side of the cam-wheel 198, before mentioned, and from which the pressure-finger 78 and the sweeper-arm 97 are both actuated at propertimed intervals.

On the shaft 128 is a spur-gear 208, which drives a train of gears 209 210 211 212 for rotating the paste-disk 47, hereinbefore described, to apply adhesive material to one edge of the binder 11 or to moisten adhesive that has been previously applied thereto. The shaft 128 also carries the cam-wheel 213, Fig. 9, having therein a cam-race 214, engaging a roller 215 on a lever 216, the upper end of which is secured to the rock-shaft 45, through which is actuated the lever-arm 44 for swinging downward the hinged suctionnozzle 32 when the suction-pump 39 is operated, as before explained, for the purpose of drawing down the leading edge of the lowermost binder in the stack of binders contained in the hopper 29. In the lever 216, Fig. 9, there is an elongated slot 217 for passage of a screw 218, which connects with a hanger 219, depending from the rock-shaft 45, and the lower portion of this hanger 219 is provided with laterally-projecting lugs 220 for supporting set-screws 221, that bear against opposite edges of said lever. By means of the screws 218 and 221 any required set or adjustment can be given to the lever 216 to vary the degree of movement to be imparted through the rock-shaft 45 to the lever 44,that actuates the hinged suction-nozzle.

As before remarked, the wrapping material may consist simply of the web 9 of waxed paper and the'binder 11, that also serves as a label, or a web of tin-foil 10 may be employed also in connection with the web 9 of waxed paper. When the twowebs 9 and 10 are employed together, there will be provided two reels 222 and 223, Figs. 27 and 28. These reels may be supported on a bar 224, projecting horizontally on one rear end portion of the machine-frame. It is preferable to pivot one end of this bar to the machine-frame, as at 225, Fig. 2, and to provide the bar with a circular slot 226 for passage of a screw 227, whereby the said bar can be easily adjusted to any required inclination, if desired. The web 9 of waxed paper is preferablyarranged on the outermost reel 222 and is drawn olf therefrom underneath the web 10 of tin-foil, which is supported on the innermost reel. The two webs 9 and 10 are passed together over one drawing-off roller 228 and beneath another drawing-off roller 229, Fig. 27, the journals or spindles of which rollers are supported in the opposite ends of a two-arm tilting frame 230, Fig. 28. This two-arm tilting frame 230 has a central pivotal support 231 in the bar 224, on which the reels 222 and 223 are mounted, and the said central support 231,

is connected, by means of a rigidly-attached
