SPECIFYCATION forming part 0f Letters Patent No. 643,623, dated February 20, 1900. Application filed January 5, 1898. Renewed Tune 28, 1899. Serial No. 722,188. (N l- To aZZ whom it may concern.-

Beit 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 certain new and useful Improvements in Package-Wrapping Machines, of which the following is a full, clear, and exact specification.

In an application for Letters Patent filed by me of even date herewith, Serial No. 722,187, I describe and show a package-wrapping machine wherein chewing-gum, soap cakes, or other articles of merchandise to be inclosed by wrappers are stored in a magazine and are discharged therefrom at timed intervals beneath a web or webs of wrapping material drawn or moved longitudinally by nippers, the web or webs being severed at a definite time to provide a wrapper, which is adjusted over an article discharged from the magazine and supported beneath the Wrapping material. The article and wrapper are then gripped by two swinging jaws, which transfer them from a point directly in front of the magazine to a folding-box, where the wrapper is folded and sealed to entirely inclose and protect the article, after which the wrapped package is removed from the folding-box and deposited at. a suitable point or delivered to a receiver 0 chute.

The chief objects of the present invention are to simplify the machine disclosed in my application above referred to; to materially reduce the number of mechanical parts composing the machine; to provide novel, simple, and efficient means for wrapping chocolate, soap cakes, and other articles of merchandise; to provide folding devices by which a wrapper-body is folded over upon the upper side of the article and its folded extremities are overlaid by a binder which completes the inelosure of the article and effectually holds and prevents the end portions of the wrapper-body from unfolding; to provide a new and improved folding-box; to provide novel and effective means for removing the wrapped packages from the folding-box and depositing them at a point desired or upon a receiver or conveyer-chute, and, finally, to generally improve package-wrapping machines, whereby a wrapper applied to an article has its end portions underlying a binder which is sealed by adhesive material for the purpose of effectually securing the wrapper proper and affording means for receiving the name of the manufacturer or any advertising matter that it may be desired to place upon such binder.

To accomplish all 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 plan View of my improved package wrapping machine, omitting the reels which carry the webs of wrapping material, but indicating a part of the latter by dotted lines. Fig. 2 is a rear side elevation showing the reel which carries the binder-web. Fig. 3 is a detail transverse sectional view taken directly at one side of the shear-blades, Fig. 1. Fig. 4 is a detail longitudinal sectional View showing the nippers nearly in the act of seizing the webs of wrapping material. Fig. 5 is a diagram showing the manner in Which one pair of nippers moves ahead or faster than the other pair to shift the wrapper-bodyor Waxed paper longitudinallya greater distance than the binder. Fig, 6 is a similar View indicating the manner in which the wrapperbody and the binder after being severed from the webs are relatively adjusted so that the ends of the wrapper-body project considerably beyond the ends of the binder. Fig. 7 is a detail transverse sectional View taken centrally through the magazine and thegripping and transferring jaws, Fig. 1. Fig. 8 is a detail longitudinal sectional view through the folding-box looking toward the front of the machine and showing the right-angular end folders spread apart preparatory to approaching each other. Fig. 9 is a detail View of the horizontally-vibrating arm or sweeper by which the wrapped packages are successively moved or swept from the folding-box onto a receiver or conveyor-chute. Fig. 10 is a detail View of the rack by which the vibratory sweeper-arm is actuated. Fig. 11 is a detail elevation showing the two reels which carry the Webs of wrapping material and the moistening-disk by which the adhesive margin of the binder-web is moistened. Fig. 12

is a detail view to more clearly illustrate the moistening-disk and the plates between which the two webs of wrapping material pass. Fig. 13 is a detail longitudinal sectional view taken on the line 13 13, Fig. 12, showing the web-supporting disk and the two plates between which the webs of wrapping material pass. Fig. 14 is a similar view taken on the line 14 14, Fig. 12, indicating the manner in which the moistening-disk is raised and lowered. Fig. 15 is a detail perspective view of the two pairs of nippers and their longitudinally-movable carrying-slides. Fig. 1G is a detail perspective view of the feed-slide by which the articles of merchandise are successively discharged from the magazine at timed intervals. Fig. 17 is a sectional plan view showing the two gripping and transferring jaws by which the article and the binder and Wrapper-body are transferred from a point directlyin front of the magazine to the folding-box. Figs. 18 and 19 are detail views of cams and vibrating levers which will be hereinafter explained. Fig. 20 is a detail view taken longitudinally through the folding-box and showing the two right-angular folders in position to approach each other for folding the ends of the waxed paper or wrapper-body down upon the upper side of the article. Fig. 21 is a detail perspective view of the wrapper-body, the binder, and the article as they stand in the foldingbox in Fig. 20. Fig. 22 is a view similar to Fig. 20, showing the position of the right-angular folders when they have moved toward each other and folded the ends of the waxed paper or wrapper-body down upon the end portions of the article. Fig. 23 is a detail perspective view of the hinder, the wrapperbody, and the articles as they stand in the folding-box in Fig. 22. Fig. 24 is a detail view showing the pressing-roller advancing for the purpose of pressing upon and securing the adhesive longitudinal margin of the binder. Fig. 25 is a detail perspective view of the binder, the wrapper-body, and the article in the position they occupy in the folding-box in Fig. 24. Fig. 26 is a detail transverse sectional view showing the completelywrapped article slightly raised in the foldingbox and being discharged therefrom by the horizontally-vibrating sweeper-arm, and Fig. 27 is a detail perspective View of the wrapped package indicated in Fig. 2

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, in which- The numerals 8 indicate perpendicular standards which constitute a magazine in which the articles of merchandise are stored in a vertical column or stack. The standards are channeled to receive the ends of the articles and to retain them in proper position and guide the same downward. The standards may be of any desired height to receive and accommodate any quantity of articles which are to be iuclosed within wrappers.

The lower open ends of the standards are sustained by suitable plates 9 or otherwise, under which a feed-slide 10, Figs. 1, '7, and 16, is movable back and forth for successively discharging the articles from the magazine. The feed-slide is constructed at its front end with forwardly-projecting arms 12,having upturned flanges 13 at their extremities, in such manner that when the feed-slide is moved rearward and the arms 12 lie under the lower open ends of the standards a single articleas, for instance, a piece of chocolate, a soap cake, or any other article of merchandise will fall by gravity upon the arms and lie between the front edge of the feed-slide and the flanges 13, whereas if the feed-slide be advanced or moved forward the article carried by the arms 12 will be moved forward and the solid part of the feed-slide will pass beneath the column or stack of articles and sustain the same until the article carried by the arms is removed therefrom, and the feed-slide is again moved rearward to place its arms directly under the lower open ends of the -magazine-standards, whereupon the operation before described will be repeated. The feed-slide is movable directly above a table 14, and at the right-hand side of this table is another table, as at 15, running 1ongitudinally of the machine and over which the wrapping material is moved longitudinally. In the present example of my invention the machine is designed more particularly to wrap chocolate, soap cakes, and other articles by placing waxed paper or a wrapperbody longitudinally around the article and then applying over this wrapper-body a binder which will overlap and hold down the folded end portions of the wrapper-body. The wrapping material is in the form of two webs, one of which is a paper-binder web, while the other is a web of waxed paper, with its leading end lying beneath the binder-web upon the table 15. The binder-web is of a width considerably greater than the width of the web of waxed paper, and one longitudinal projecting edge of the binder-web is provided on its under side with adhesive for finally securing the binder in position upon the article. Near the magazine and above the inner end of the table 15, over which the webs move, are located two web flattening and guiding plates 16 and 17. The narrow waxed-paper web passes under the lower plate 16 through a guide-groove in the table 15, while the binder-web passes between the two plates 16 and 17. The plates may be constructed with elastic fingers 18, which press downward toward the table 15 and serve to hold the two webs in such manner that their leading ends will be properly maintained in correct position to be seized by the longitudinally-movable nippers hereinafter explained.

A cutter for severing the webs into wrapper-sections each of which is composed of a waxed-paper wrapper body and binder is located directly at the left-hand side of the web flattening and guiding plates 16 and 17, or, in other words, the cutter is located between these plates and the magazine. This cutter, as in my application before referred to, is composed of two pivoted shear- blades 19 and 20, operated at timed intervals, as will hereinafter appear, so that when the leading ends of the webs have been drawn longitudinally in front of the magazine a distance sufficient to provide the material necessary for a complete wrapper the shear-blades quickly close and smoothly sever the webs. As the webs are drawn longitudinally in front of the magazine the feed-slide 10 is moved forward and an article lying on the arms 12 will be carried forward and placed beneath the wrapper-body, and therefore the complete wrapper lies above the article, and this article and the wrapper will stand in such position that they may be carried to a folding-box through the medium of two gripping and transferring jaws 21 and 22, Figs. 1, 3, 7, and 17, forming, respectively, fixed parts of yoke- frames 23 and 24. The yoke-frame 24 of the grippingjaw 22 is sleeved or loosely mounted upon a short longitudinal shaft 25, arranged in suitable bearings in parallel plates running from front to rear of the machine, at or about the center thereof, one portion of this yokeframe being rigid with a pinion 26. This pinion is loose on one end of the shaft 25, and on this shaft is a sleeve 27, secured thereto. The yoke-frame 23 of the gripping-jaw 21 forms part of the sleeve 27, fastened to the shaft 25, which latter is provided at one end with an attached pinion 28. The pinion 26 of the yoke-frame 24 engages a segmental rack 29, while the pinion 28, secured to the shaft 25, engages a segmental rack 30. The segmental racks are independently operated,

as will be hereinafter explained, and they swing back and forth in a direction from frontto rear of the machine. In what may be termed the normal position of the gripping- jaws 21 and 22 the jaw 21 lies nearly flush with or slightly below the inner end of the table 14, which is under'the magazine, and therefore when an article is discharged from the magazine by the feed-slide 10 as the paper webs are drawn longitudinally into a position in front of the magazine the article is pushed under the two webs and is placed directly over the jaw 21.. During this time the gripping-jaw 22 lies in the folding-box, and after the binder, the wrapper-body, and the article are in correct position over the jaw 21 the yoke-frame 24 is swung in the arc of a circle and its jaw 22 leaves the foldingbox and cooperates with the jaw 21 to firmly grip and hold the article, the binder, and the wrapper-body, after which the two jaws, gripping the article and the binder and wrapperbody, swing forward in unison in the arc of a circle and the jaw 22 enters the folding-box, whereby the article, the wrapper-body, and binder are reversed in their position or turned upside down, and the article will lie above instead of under the binder and wrapperbody. The jaw 21 will then move back independently of the jaw 22 to the position first mentionedto wit, substantially flush with or slightly below the inner end of the table 14.

The folding-box is in the form of an opentop rectangular receptacle having vertical front, rear, and end walls.

The gripping-jaw 22 is in the form of a plate substantially coextensive with the interior of the folding-box and is provided with an opening 22, as seen in Figs. 1 and 17, designed to receive the rear wall of the foldingbox, whereby the jaw is adapted to enter said box.

I will now proceed to describe the nipper mechanism by which the Webs are drawn or pulled longitudinally into a position in front of the magazine and over the article to be wrapped. There are two pairs of nippers, composed of fixed jaws 31 and movable jaws 32 and 33, as best seen in Figs. 1, 4, and 15. The fixed jaws are carried by the inner ends of horizontally-movable slides 34, and to the inner end portion of one slide the nipper-jaw 33 is pivoted, as at 35, and is articulated at one side of its pivot to one extremity of a lever 36. The movable jaw 32 of the other nippers may form a rigid part of a lever 37, pivoted, as at 38. The reason for the difierences in the construction of the two nipper-jaws is that the nipper-jaw 33 closes upward against a fixed jaw, while the nipper-jaw 32 closes downward against a fixed jaw. The outer ends of the levers 36 and 37 are provided with roller-studs, as at 39, adapted to travel in longitudinal guideways, as at 40, in opposite sides of a bar 41, which is pivoted at its outer end, as at 42, to a fixed part 43 of the ma-' chine-frame. The slides 34 are dovetailed to opposite sides of a fixed horizontal plate 44, forming an extension of the machine-frame, and these slides are pivotally connected by links, as at 45, with the upper ends of vibrating levers 46, which at their lower ends are mounted on a fixed shaft or stud 47 in such manner that when the levers 46 are reciprocated the slides and nipper-jaws are correspondingly reciprocated. The bar 41 is adapted to be raised and lowered by a vertical rod 48, connected therewith at its upper end, so that if the bar 41 be raised by elevating the rod 48 the levers 36 and 37 will be so actuated as to close the pivoted nipper-jaws 32 and 33 for the purpose of gripping the leading ends of the webs of wrapping material, and, conversely, if the bar 41 be lowered the levers 36 and 37 will cause the pivoted nipper-jaws to open and release the leading ends of the Webs. The cams and connections for operating the vibrating levers 46 and the vertical rod 48 at timed intervals will be hereinafter explained in the description pertaining to the camshafts and driving devices of the machine.

In Figs. 1, 4, 5, 6, and 11 the leading end portions of the paper webs are indicated by the numerals 49 and 50, the web 49 being the binder-web and the web 50 the waxed paper. These webs are carried by rotatable reels 50 and 50, supported in any suitable manner by a part of the frame of the machine. Then the slides 34: are advanced, the bar 41 is depressed and the nippers are opened to seize and grip the leading ends of the two webs, one pair of nippers being arranged to seize the binder-web 49 and the other pair to seize the waxed-paper web 50, which, as before stated, is of a width considerably less than the width of the binder-web. When the nippers are in position to grip the ends of the webs, the bar 41 is raised and the nipper-jaws close against the fixed jaws, after which the slides 34: by their connection with the vibrating levers 46 are retracted or commence to move outwardly, thereby drawing or pulling the webs between the web flattening and guiding plates 16 and 17 into a position in front of the magazine and over the grippingjaw 21. As the webs are drawn longitudinally in front of the magazine an article is discharged therefrom and placed over the jaw 21 under the webs. XVhen the requisite quantity of wrapping material has been drawn bythe nippers into a position in front of the magazine, there is a pause in the longitudinal motion of the nippers, and at this instant the shear- blades 19 and 20 quickly close and sever the webs to produce a wrapper composed of a wrapper proper and a binder. (See Fig. 5.) Immediately thereafter the nippers again move a limited extent in an outward direction to shift the wrapper-body in correct position relatively to jaw 21, and then there is a pause in the motion of the pair of nippers which seizes the waxed paper or wrapper-body,while the nippers which seize the binder continue their outward motion and adjust the binder into such position that the waxed paper or wrapper-body projects from opposite ends thereof, as in Fig. 6. In other words, as the nippers recede and pull the webs longitudinally the nippers which grip the waxed paper move ahead or slightly faster than the nippers which grip the binder-web until the requisite quantity of wrapping material is drawn 1ongitudinally, whereupon there is a pause in the motion of both pairs of nippers, and the quick-acting shear-blades sever the webs, after which the two pairs of nippers continue the receding motion; but now the pair of nippers which grip the binder web move ahead or slightly faster than the nippers which grip the waxed paper, whereby the binder is shifted on the waxed paper into such position that the latter extends from opposite ends of the binder to provide the material necessary to be folded down upon the upper side of the article.

In Fig. 5 the shear-blades have just severed the webs to produce a wrapper comprising a wrapper-body and a binder. It will be seen that one pair of nippers has drawn the waxed paper slightly beyond one end of the binder.

The two pairs of nippers then shift the complete wrapper centrally over the grippingjaw 21, which is the jaw over which the artiole is placed by the feed-slide 10. In Fig. 6 the article is represented as lying upon the jaw 21, the waxed-paper wrapper-body is located above the article, the binder has been shifted into correct position centrally over the wrapper-body,the shear-blades are opened, and the gripping-jaw 22 is approaching the jaw 21 to grip the complete wrapper and the article preparatory to transferring them to the folding-box. As before stated,the binderweb is wider than the waxed-paper web, and one longitudinal margin of the binder-web is provided with adhesive to cement or secure the wrapped package. The adhesive margin requires to be moistened, so that it can be subsequently pressed down and secured, which is effected as the web travels toward the shearblades through the medium of a rotary moistening-disk 51, Figs. 11, 12, 13, and let, supplied with moistening liquid from a tank 52 by disks 53 and 54,-, the latter dipping into the water in the tank and supplying liquid to the disk 53, which in turn supplies the moistening-disk 51. The disk 51 is adapted to press against the adhesive margin of the binderweb, and these disks are mounted on shafts having pinions geared together and positively driven by a pinion 55, rotated by a gear-wheel 56, which is operated, as will hereinafter appear. The moistening-roller is adapted to be raised at regular intervals to press against the adhesive margin of the binder-web, as will be explained at the proper time.

I will now proceed to describe the folding devices which cooperate with the folding-box to wrap the package. The folding-box is of the same dimensions substantially as the article which is to be wrapped, and the rightangnlar end-folders 57, Figs. 8, 20, and 22,

extend approximately at right angles from the upper ends of two vibrating arms 58, pivoted at their lower ends to the base of the machine. The two end-folders 57 are adapted to move toward each other, Fig. 22, to fold the end portions of the waxed paper down upon the upper side of the article lying in the folding-box, it being understood that the gripping-jaws have previously placed the article and the complete wrapper in the foldingbox and that the walls of the latter have turned the waxed paper and the longitudinal edges of the binder to a perpendicular position or nearly so, as will be best understood by reference to Figs. 20 and 21. The arms 58 are moved toward and from each other by the means which will be hereinafter explained. After the end portions of the waxed-paper wrapper-body have been folded down upon the upper side of the article of merchandise one longitudinal edge of the binder is folded down upon the end portions of the Waxed paper through the medium of a front longitudinal folder 59, Figs. 24 and 26, and subsequently the opposite longitudinal side of front to rear of the machine.

the binder is folded down, and its adhesive margin is secured through the medium of a rear folder 60, composed of an elastic pressing-roller mounted in the right-angular up per end of a vibrating arm 61. The front folder 59 is also mounted upon a vibrating arm 62, and these two arms are pivoted at their lower ends to the base-frame,so that they can swing back and forth in a direction from The specific means for swinging these arms will be hereinafter set forth in detail. The front folder 59 commences to move rearward as the end-folders 57 approach each other, and subsequently when the elastic pressing or folder roller is rolling over the adhesive margin of the binder the front folder 59 moves forward out of the path of the elastic roller to enable the latter to complete its work. The pressing or folder roller then recedes or moves rearward, and the completely-wrapped package will lie in the foldlng-box upon the gripping-jaw 22. It is now essential to remove the wrapped package from the folding-box, and this is accomplished through the medium of a horizontally oscillating or vibrating sweeper-arm 63, secured to the upper end of a vertically-arranged rock shaft 64, actuated by devices hereinafter explained. The first motion of this sweeperarm after the package has been wrapped and the folders have moved away from the folding-box is to move rearward over the package and out of the path of the same. At this instant the gripping-jaw 22 slowly rises and then pauses in its motion (see Fig. 26) to place the wrapped package substantially on a level with a receiver or conveyer chute 65. The sweeper-arm now swings forward and sweeps the wrapped package from the gripping-jaw 22 onto the receiver or conveyer chute. The sweeper-arm then pauses in its motion for a subsequent operation and to place it out of the path of the gripping-jaw 22 as the same swings rearward to cooperate with the jaw 21 to grip another article and a wrapper. The receiver or conveyer chute may be horizontally arranged, so that the wrapped packages will be moved along the same, or the chute may be inclined to deliver the wrapped packages into a suitable receptacle.

I will now proceed to describe in detail the mechanical devices for positively actuating the working parts hereinbefore set forth. I adopt this order of description in that I believe that the construction and operation of the entire machine will be better understood.

A longitudinal line-shaft 66, Figs. 1, 2, 3, and 7, is arranged in suitable bearings at the front of the machine and at one end carries a miter-gear 67, meshing into a miter-gear 68 on a transverse primary counter-shaft 69. The line-shaft 66 at the front of the machine is provided at one end with a gear-wheel 70, of comparatively large diameter, driven by a pinion 71 on the inner end of a main driveshaft 72, journaled in a suitable sleeve-bearing 73. This drive-shaft is provided at its outer end with a loose pulley 73, designed to be driven by a belt connection with a powershaft; but obviously it can be operated manually, if desired. The main drive-shaft 72 is provided with a clutch-section 74, designed to be operated by a suitable clutch-lever, (not necessary to illustrate,) so that it can be thrown into and out of engagement with a clutch-section 75 on the pulley 73 to lock the latter to or unlock it from the drive-shaft, whereby the machine may be started and stopped whenever required.

The feed-slide 10, by which the articles are discharged at timed intervals from the magazine, is pivotally connected by a link 10 or otherwise with the upper end of a vibrating lever 76, Figs. 3 and 7. This lever is connected by the rod 77 with a vibrating cam-actu ated lever 78, pivoted at its lower end on a short shaft 79, mounted in bearings at the front of the base of the machine: The lever 78 is swung back and forth at timed intervals through the medium of a suitably-constructed cam 80, mounted on the front line-shaft 66. The lever 78 carries a roller-stud engaging the cam, and the latter is so constructed as to advance the feed-slide 10 as the webs are drawn longitudinally in front of the magazine for the purpose of placing the article which is to be wrapped beneath the wrapping material and over the gripping-jaw 21. After the jaw 22 is swung rearward and cooperates with the jaw 21 to seize the article and the wrapper and the article is raised from the arms 12- of the feed-slide the latter is given its back stroke by the cam to place the arms in a position directly beneath the lower ends of the channeled magazine-standards 8, whereupon another article will be deposited by gravity upon the arms and lie between the front edge of the feed-slide and the upturned flanges 13 of the arms.

As before explained, the webs are severed by the two shear- blades 19 and 20 after the webs have been drawn longitudinally a distance sufficient to provide the material necessary for a complete wrapper. The pivoted end of the lower shear-blade 20 is provided with an attached fender-finger 20, Fig. 3, which moves in unison with said shear-blade. When the shear-blade 20 moves down, the finger 20 also moves slightly down and serves to prevent the leading end of the binder-web curling up in proximity to the pivoted points of the shear-blades. This finger may also serve to strip the leading end of the binderweb from the shear-blade 19, near the pivotal end of the latter, as said shear-blades rise. The shear-blades are automatically opened and closed at timed intervals, as I will now explain. The shear-blades, Figs. 1, 2, and 3, are pivotally mounted upon a common axis 81. The upper shear-blade 19 is constructed with a tailpiece 82, connected by a link 83 with one arm of a bell-crank lever 84, fixed on a rock-shaft 85, arranged in a suitable bearing. The lower shear-blade 20 is connected by a link 86 with acrank-arm 87, fixed to the rock-shaft 85, the construction being such that when the bellcrank lever is rocked the shear-blades are opened and closed. The upwardl y-projectin g arm of the bell-crank lever 84 is connected by a rod 88 with the upper end of a lever-arm 89, pivoted at its lower end, as at 90, and having near its upper end a lateral roller-stud 91, acted upon by a cam 92 on the rear end of the counter-shaft 69. The lever-arm 89 carries a trip-dog 93, pivoted intermediate its ends thereto and having one end provided with a hook 9i and the other end lying in the path of a laterally-projecting trip-pin 95 on the cam 92. The lever-arm 89 is drawn toward the cam 92 by a suitable spring and normally, as when the shear-blades are completely opened, the hook 94 of the trip-dog 93 engages and is held by a fixed stop-lug 97. The hooked end of the trip-dog 93 is pressed downward into engagement with the stop-lug by a suitable spring. The periphery of the cam 92 is constructed with a recessed or cutaway portion, so that during the rotation of the cam, when the lateral trip-pin 95 acts upon one end of the trip-dog 93 to raise the hook 94 at the engagement with the stop-lug 97, the spring 96 pulls the lever-arm 89 toward the cam, and, as the cut-away portion of the cam will at this time register with the rollerstud 91, the latter can pass into the recessed or cut-away portion of the cam and the swinging action of the lever-arm will pull the conmeeting-rod 88, swing the bell-crank lever 8t, and turn the rock-shaft 85 in the direction necessary to raise the links 83 and 86, thereby quickly closing the shear-blades to sever the webs and produce a complete wrapper. As the cam 92 continues to rotate the rollerstud 91 will ride upon the eccentric part of the periphery of the cam and force the leverarm 89 in a direction away from the cam, so that the shear-blades are opened, the spring 96 is stretched, and the hooked end of the trip-dog 93 is caused to engage the stop-lug 97, thereby holding the shear-blades in their open position for a subsequent operation, as before set forth. The shear-blades can be more or less slowly opened, and when opened they are held in this position a sufficient length of time for the folding operation to be com pleted and the two webs to be drawn longitudinally in front of the magazine a distance suflicient to produce a complete wrapper.

The yoke-frames 23 and 24-, Figs. 1, 7, and 17, which carrythe gripping and transferring jaws 21 and 22, by which the article and the complete wrapper are gripped and transferred from a point directlyin frontof the magazine to the folding-box, are operated at timed intervals through the medium of devices which I will now explain. The segmental racks 29 and 30, Figs. 1, 3, and 7, form parts of the upper ends of swinging arms 99 and 100,pivoted at their lower ends upon a stud or shaft 101. The rack-arm 99 is connected bya link 102 with a vibratory arm 103, mounted at its lower end on the short horizontal shaft 79. This vibratory arm engages a cam-raceway in one side of a cam 104, mounted on the front line-shaft66. The rack-arm 100 is connected by a link 105 with a vibratory arm 106, also mounted at its lower end 011 the short horizontal shaft 79. The arm 106 engages a camracewayin one side of the cam 107. The camraceways of the cams 104 and 107 are of such construction that during their rotation they cause the rack- arms 99 and 100 to move back and forth for rotating the pinions 26 and 28.

If the gripping and transferring jaw 22 lies in the folding-box, as in Figs. 1 and 7, and the jaw 21 is in proximity to the table 14: and the main drive-shaft is operated to turn the primary counter-shaft, and thereby correspondingly turn the front line-shaft, and also assuming that the webs have been drawn 1ongitudinally over an article placed above the jaw 21, the rack-arm 99 will be drawn toward the front of the machine by the action of the cam on the lever-arm 103, thereby turning the pinion 26 in the direction necessary to swing the yoke-frame 24: away from the folding-box rearward to cause its jaw 22 to cooperate with the jaw 21 to grip and hold the article and the wrapper. After this occurs the two rackarms 99 and 100 will be moved in unison toward the rear of the machine, and consequently both pinions 26 and 28 will be rotated in unison in the direction required to swing both gripping-jaws forward while holding the article and the wrapper and cause the jaw 22 to enter the folding-box. The rack-arm 99 will then remain stationary; but the cam 107 will act upon the lever-arm 106, which is conv nected with the rack-arm 100, and swing the same forward, whereby the gripping and transferring jaw 21 will be swung rearward independently of the jaw 22 and placed in proper relation to the table 14, while the gripping-jaw 22 remains in the folding-box until after the completion of the folding operation. During the folding operation and while the nippers are advanced and retracted to draw or pull the two webs longitudinally in front of the magazine both rack- arms 99 and 100 remain motionless. The same order of procedure occurs after each package that is wrapped. The gripping of the article and wrapper and their transfer by the grippingjaws while held in fixed relation to one another from a point near the magazine to the folding-box near the front of the machine effectually prevent displacement of the article and wrapper relatively to one another, and therefore all packages will be correctly wrapped alike. The lever-arms 46, by which the slides 34 of the nipper mechanism are actuated, have link connections 108 and 109 with the lever-arms 110 and 112, mounted at their lower ends 011 a shaft or stud 113 and engaged with suitable cam-raceways in opposite sides of a cam 114. The cam-raceways are of such construction as to produce the particular motion of the nippers hereinbefore explained. During the time the gripping and transferring jaws 21 and 22 are moving the slide-bars 34 and the nippers remain motionless, except that as the jaw 21. approaches the table 14 the rear lever-arm 110 is acted upon by the cam-raceway of the cam 114, so that the rear slide 34 commences to advance and places its nippers in alinement with or in correct position relatively to the nippers of the front slide 34. Both the slides then advance in unison, and as they approach the leading ends of the webs, Fig. 4, the pivoted bar 41 is lowered for the purpose of opening the nipperjaws. The bar 41, as before stated, is connected with the upper end of the rod 48 and at its lower end is pivoted to a crank-arm 115 of a rock-shaft 116, having a second crank-arm 117, acted upon by the'peripheral portion of a cam 118. The cam is so constructed that at timed intervals the crank-arm 117 will be operated to turn the rock-shaft 116, and thereby pull the bar 41 downward to open the nipper-jaws, while at other times the part-s will be operated to raise the bar 41 to close the nipper-jaws. The nipper-jaws are closed immediately after they pass into posit-ion to seize the leading ends of the webs, at which instant the bar 41 is raised, thus closing the nippers. WVhen this occurs, the cam-raceways in the sides of the cam 114 commence to act upon the lever-arms 110 and 112 to move them in the direction necessary to impart the retracting motion to the slides 34, so that the webs will be drawn longitudinally in front of the magazine and over an article placed or being placed above the grippingjaw 21. As the nippers are retracted the slide carrying the nippers which grip the waxed paper move slightly faster than the slide-bar carrying the nippers which grip the binderweb for the purpose of drawing the leading end of the waxed paper considerably ahead of the leading end of the binder-web. After the requisite quantity of the two webs has been drawn in front of the magazine the shear-blades sever the webs, during which time there is a pause in the longitudinal motion of both pairs of nippers to afford time for the cutting action of the shear-blades. Subsequently the nippers which grip the binder are further retracted and the binder is shifted along from the position indicated in Fig. 5 to the position indicated in Fig. 6, where it is centrally placed relatively to the binder and the waxed paper in such manner that the latter projects at opposite endsbeyond the end of the binder. The gripping and transferring jaw 22 now moves out of the folding-box onto the wrapper and article and they are gripped by the two jaws, as before explained. The nippers are then further retracted to move them out of the path of the article and wrapper,whereupon the gripping and transferring jaws swing forward and place the article and the complete wrapper in the folding-box, as I have hereinbefore described. As before stated, the longitudinal edge of the binder-web projects in front of the web of waxed paper, and this projecting edge is provided with adhesive moistened by the moistening-disk 51. The shaft of the moistening-disk is geared to the shafts of the disks 53 and 54, as before explained, and this gearing is driven by the drive-pinion 55, op erated by the gear-wheel 56. This gear-wheel is mounted on the inner end of a secondary counter-shaft 119, geared to the front lineshaft 66 by miter-gears 120 and 121. The frame or support 122 of the disks 51, 53, and 54 is susceptible of rocking vertically on the shaft of the disk 54 as a center, so that this frame can be raised to move the moisteningdisk 51 into contact with the adhesive margin ofthe binder-web. The frame 122 is raised and lowered at regular intervals through the medium of a link connection 123 with one end of a rocking lever 124, the other end of which is connected with another rocking lever 125, act-ed upon by a part of the cam 118, so that at regular intervals, or rather as the webs are being moved longitudinally, the rocking levers are actuated to raise the frame 122, and thus press the moistening-disk more or less firmly in contact with the adhesive margin of the traveling binder-web.

I have previously explained that the webs are pressed downward by the elastic fingers 18, and preferably the leading end of the web of waxed paper is made to rest upon two looselyjournaled disks or wheels 18 by which such leading end is supported,while it is susceptible of being easily moved longitudinally. The pivoted vibrating arms 58 are swung toward and from each other by rod connections 126 and 127,wit-h vibratory leverarms 128 and 129 engaged with and actuated at proper timed intervals by cam-raceways in the opposite sides of a cam 130 on the primary counter-shaft 69. During one part of the rotation of the cam the vibrating arms 58 are swung toward each other, and consequently the right-angular end-folders 57 are moved toward each other over the ends of the folding-box to fold the end-folders of the waxed paper down upon the upper side of the article. D urin g another part of the rotation of the cam 130 the arms 58 are moved away from each other and the right-angular folders are retracted in a direction away from the ends of the folding-box and out of the path of the front and rear longitudinal folders 59 and 60. The vibrating arms 61,0n which the folder-roller is mounted, is connected bya link 131 with a vibrating lever-arm 132, mounted at its lower end on the shaft 79 and acted upon by part of a cam 133 on the front line-shaft 66. The

vibrating arm 62, which carries the right-angular front folder 59, is connected by a link 134 with the upper end of a lever 135, pivoted intermediate its ends at 136 and acted upon at its lower end by a part of the cam 107. The parts of the cams 107 and 133 which act upon the levers 132 and 135 are so constructed that the front longitudinal folder 59 will first advance, and subsequently the rear folder-roller 60 will advance, and when it about reaches the edge of the right-angular folder 59 the latter will be moved forward, so that the folder-roller 60 can roll over the binder and effectually seal its adhesive margin. The receding motion of the folder 59 is effected or facilitated by the lever 61 of the folder-roller 60, acting upon one end of an adjustable screw-pin 137, projecting from the arm 62, which carriers the front folder 50, and therefore it is only necessary for the cam-raceway which operates the lever 135 to positively move this lever in the direction necessary to move the folder 59 over the folding-box to produce the first longitudinal fold of the binder. After the package is wrapped and its adhesive margin is secured, the sweeperarm 63 moves rearward, so that it will be placed in a position in rear of the wrapped article. At this instant the rack which operates the yoke-frame carrying the grippingjaw 22 will cause the latter to slightly rise and then pause, Fig. 26, the purpose of this being to lift the wrapped package approximately on a level with the receiver or conveyerchute G5. The sweeper-arm is now made to move forward, so that it sweeps the wrapped article from the jaw 22 onto the receiver or conveyerchute. The sweeper-arm 63 is vibrated in a horizontal plane at proper-timed intervals by rocking its perpendicular shaft 64:, which is effected through the medium of a toothed part 138 on the shaft engaged with a horizontal rack 139, which at regular intervals is moved back and forth for the purpose of rocking the shaft 64. The rack 139 is provided with a lateral pin 1&0, Figs. 1 and 10, connected by a rod 141 with a pendent arm 142, pivoted at its upper end, as at 143, Fig. 3, and acted on at its lower end bya cam-racewayin one side of the cam 104. At proper timed intervals the cam 104 moves the rack-bar 139 rearward and then pauses, by which means the sweeperarm 63 is moved rearward and is placed in rear of the wrapped article, where it remains motionless fora limited time. After the grippin g-jaw 22 slightly rises and then pauses, as before stated, the rack-bar is moved forward and the sweeperarm is horizontally moved forward to sweep the wrapped article from the jaw 22 onto the receiver or conveyer-chute.

An important part of the present invention resides in the means whereby the end portions of the waxed paper or wrapper-body proper are folded over a considerable distance upon the upper side of the article in the foldingbox and the binder is folded down upon the folded end portions of the waxed paper or wrapper-body proper, thereby overlying and efiectually securing such end portions and producing a very securely-wrapped package.

Inasmuch as any person skilled in the art can construct cams suitable to effect the m ovements of the working parts hereiubefore explained, it is not deemed essential to explain in detail the exact contour of the cams illustrated, and it is not to be understood that the present invention is confined to any particular form of cams, as it is only essential that they be properly constructed to move the working parts at timed intervals, as will be well understood by any person skilled in the art.
