To all whom it may concern Be it known that we,JAMr.s D. REIFSNYDER and GEORGE H. FATH, citizens of the United States, residing in Philadelphia and State ,of Pennsylvania, have invented new and useful Improvements in Machines for Forming Sealed Wrapped Packages, of whichl the following isa specification.

rl`his invention relates to machines for applying wrappers to-packages for theV purpose of forming what are known as sealed wrapped packages, and is an improvement on that type of box covering machines set forth in Letters Patent granted to Philip S. Smith, No. 691,329, dated January 14, 1902., and No.` 778,805, dated December 27, 1904, and is an adaptation of machines of this class for the special purpose set forth.

The lobject of this-invention is to provide a machine for foldirdlg and sealing a wrapper around packaged materials especially such j and' sealed against the four vertical sides of materials as are packed boxes.

Theipackage and the cover coated with an adhesive fand applied to one wall of the package are fed into the machine and, passing therethrough, thex wrapper is iirst folded K the package, afterwhich the projecting upwrapper secured to the bottom of the box do not cover the entire bottom, but extend present machine it standing ends of said wrapper are turned overand secured to the remaining side of the package, which in the case of a box is preferably the bottom, said turned over ends l sealing theV cover to the box and closing thel space between the cover and box against entrance of foreign matter. The ends of the thereover only sujiiciently far to secure ,atight seal? -An important feature 'of the invention.J

resides in the presser block or plunger by means of which the package is pushed' through the folding mechanism. In the presser block 'of the same area as the package tobe covered inorder that the final Yturned "v over ends of the wrapper may be.

pressed against the upper surfaceof the package in order'to secure a' perfect adhesion of these ends to the package. It is also necessary to have a presser block of less area than the package for the purposeof Specification of Letterslatent.

holding the package in position while the i -throughout itsrange of movement andremains in contact with the package until ready for ejection from the machine. The

larger presser block is connected yieldingly to the smaller pressery block and is moved thereby `simultaneously a. certain distance, after which it pauses for a predetermined time while the ends ofthe wrapperare being folded over upon the package, and then completes its movement, pressing said ends tightly against the upper surface of said package. v

Another important feature of the invenv tion is a gage for positioning packages fed to the machine absolutely in line with the presser blocks or plungers, said gage being movable with the plungers through a por- -tion of their travel, or until the package has been securely gripped between the pluggers and adepressible platen pressing respectively against Itheupper and-lower faces of the package.

y A further feature of the invention is directed to a mechanism for removing packages from the machine after the covering operation has been completed. This mechanism is in the nature of a slowly' moving pusher, positively actuated at the completion of each wrapping operation, and, after ,ejecting the package, is automatically returned by a quick movement to normal position before the next wrapping operation takes place.

With'thesemand other objects in view the invention consists of a novel combination and arrangement of parts hereinafter described 'and illustrated in the accompanying drawings, in which- Figure 1 is a side-elevation of the machine from the front, Y-poxrtions being shown 1n section to more clearly illustrate the inven'f tion. Fig. 2 is an end lelevation partly in section as seen from the left of Fig. 1. Fig. 3 isa rear elevationof the upper portion of the machine, illustrating more clearly certain features of the invention. Fig. 3 is a. detailview in plan showing how the tuck-in lingers fold the projecting ends lof the wrapper over 'the upper side kof the package. Figs. 4 and 5 are views similar to Fig. 3,

showing the parts there illustrated in dilferent positions. Fig. 6 is a horizontal sectional view on the line 6-6 Fig. 5. Fig. 7 is a plan view of the wrapper blank. Figs. l8v to 13 are detail views of portions of the wrapper mechanism showing by progressive stages the manner in which a wrapper isfolded and secured about a package. Fig; 14 is a perspective view of a sealed wrapped package. Fig. 15 is a dtail sectional view -of a portion of the wrapper -folding mecha-l nism. Fig. 16 is an elevation' partly in sec-' tion of the' package ejecting mechanism; Fig. 17 is a plan view partly in section of the same mechanism.

Similar reference characters are used throughout .all the figures to Iindicate like' arts. P Referring first to Fig. 7, A is the wrapper as a'fwhole made substantially of the form shown, on thecentral part a ofwhich the package is placed after the upper surface of the wrapper has been completelycovered with an adhesive. j a1, a are flaps projecting from opposite sides of the part a, of which! the flaps a1 are turnedup by the first 'folding operation against corresponding sides the upper surface of the same. vThe side ofthe package in which position side laps a2 thereon will project beyond the other sides of the ypackage and end laps a3 above laps/jai are next folded around the corners of the package against the'sides thereof,

- wrapper therefor are carriedj during the after which the flaps a4 are folded againstl said sides and cover the endlaps a?. F roni= -the flaps a4 Aendlaps a5 project upwardly .above thei package, and in connection with the end laps a3, are foldedv over the upper sideof said package to completevthe wrap ing and sealing thereof. A

Mounted 'upon legs 20 which rise from the floor is a table 21', having-an opening 22 in its center, through which. projects the wrapper folding mechanism, and also, through which the package ,and the course of the wrapping operation. v.Rising from the top of the table at the right side thereof is a vertical standard 23 from which anarm or bracket y24 projects toward the centerline of-the machine. Secured to said arm or bracket is an upright plate 25 provided on `its front with -two vertical guides v26 between which` is mounted a slide 27, on-

the lower end of 'whichis fixed a pusher block or plunger 28 movableyin a vertical line through theopening 22 inthe `tablef2`1 by means of a counterbalanced lever 29 -ful-f crumed at 30 on an arm 31 projecting out from the standard 23. The free end of the lever-29 is pivoted to a link 32, adjustable -driven thereby is a worm wheel 40 keyed on the lower end of an upright shaft 41 stepped in a.y bearing supported on the plate35, said shaft extending vertically behind the standard 23 ynd above the same and turning inl suitable bearings on the standard. -Onl the upper end ofthe shaftI 41 is a drum 42 in the periphery of which are twocam grooves 43, 44, that extend entirely around said Y drum, the lower ca`m 43 actuating the lever f` 29 by means of a'studior roller45carried by.,

said lever.

On the lateral sides of the slide 27 at the ably mounted afrod 47, said rod extending vertically through .suitable openings in the plate 35 to a suitable point above said plate where they are connectedv by a cross head 48.v

The lower endsof the rods 47 are joined tobottom are lugs 446, 'in each ofiwhiclr is slidgether by'a plate 49 to which is removably l connecteda second pusher block or plunger 50 larger than the-pusher block 28 and pro-.

with a recess or 'depression 51 in its side into' which said pusher blcck 28 vide und enters, and when` so entered the under surfaces of the .two pusher blocks lie in the Asame plane, as clearly 'shown in Figs. 1, 2

and 8 of the drawings. The pusher blocks 28 and 5are jmade to be easily removable from .'theparts by which'they are carried'.

for the reason that the machine being adapted to operate on packages of different sizes the blocks must be changed to suit the packfages, block 5,0 having the same dimensions as the upper surface of the package, while block 28 is somewhatsmaller in eachv dimension.- Movement is imparted to thelarger pusher block 50 from the slide 27 by means of a resilient or yielding connection therebetween,'which in the present instanceI` is in theform of a coiled spring 52. connected at one end to4 a pin- 53projecting from said slide 27, and at the other end toa pin 54- -secured in -thefcross head 48 connecting theA rods 47 at their upper ends.

.. Rotation vof the cam drum 426m the direcv tion indicated bythe arrow will cause the lever 29 to swing downwardly and move the `slide 27 and the pusher block or plunger 28/ thereon through the table 21. 'llhe larger pusher block or plunger 50 will move simul- V taneously therewith because ot theconneotion 52 between the parts, until at a certain point in the movement of said plungers, the larger plungerL 50will be temporarily arrested but the smaller plunger 28 will continue its movement until it has reached itslowest limit, to be followed .later by the plunger 50. The two will then be returned together to their uppermost position indicatedsin Fig. l.

Slidableverticallyin ears 55 projecting laterally from the right and leftsides of the plate are rods 56 connected at their upper endsby a plate-57 whichl extends behind the slidel 27 at a. point between the top of the plate 25 and the cross head 48; The lower ends of the rods 56 are secured in the end of a U-shaped frame or bar 58 that curves rearwardly behind the rods 47, and the .sliding Stem 27 in order to clear the same, said frame l or barbeing connected by means of a link 59.

' toone end of a lever 60 pivotally mounted on the arm or bracket 24 intermediate its.-

ends and having at its opposite end a pin or rollerV 61 extending into the upper cam groove 44 on the drum'42. The lever 60 is' rocked in a vertical direction when tlie cam drum 42 rotates, vand through the link 59 raises and lowers the frame or bar 58. Near plungers 28 and 50 in their descent have reached the predetermined point heretofore mentioned, the lower end of the pin 63.will

contact with the plate 62, thus 'preyenting' v further descent ofthe plunger 50.

At the proper time, however, the lever is further depressed by the cam groove 44 and releases the pin 63, permitting the plunger 5,0 under its own weight andthe resiliency of spring 52 to finish its travel with .a quick Sudden movement for a purpose hereinafter' set forth. v

Fixed in uw ends ef the ufshapea flame' or bar 58 and projecting to the right-and Aleft thereof in a horizontal din'ection and 'preferably in line, are two arms 64 upon each of which isadjustably mounteda coller which may be moved longitudinally on said'arm.v Each collar 65 supports :a finger 66, adjustable inal direction at right angles teV the axis of the arms 64. each linger at its rear .end is fa downwardly projecting angle shaped gagelplate (3T-,which in the normal position olf the parte shown in Fig. l, projects below the under surfaces ofthe plungers 28 and 50. These gage plates lie close to the rear corners of the pusher block or plunger 50, as shown in Fig. 6, and serve as aguide to position the box or package B that is to be wrapped, relatively to the plungers when inserted in the machine.

Secured to the plate 35 whichv sustains the to slide in la vertical direction'a hollow steml 7() on the upper end of which is secured a platen 71 that serves as a Support for the wrapper and the article to be wrapped during its passage through the wrapping mechanism. The platen is held above the plane of the table 2l by yielding pressure, in the 4bracket 7 9,

present instance a spiral sprungv 72 within the hollow stem serves the purpose. When the plungers 28 and50 and the frame 58 with the gage plates or'ngers 67 descend with the wrapper and. the article to be wrapped, said article and wrapper engage the platen, and are vheld by and between said platen `and the plungers during their progr'ess through the 'folding mechanism, the spring 72 returning the platen and the wrapped package to initial position after the wrapping operation has been completed. The folding mechanism employed in this chine is 'in the main, substantially the same as. that shown in the hereinbefore menbearings for the worin shaft 37 is a support tioned patents granted to Philip S. Smith, f

and therefore, will be referred to here only in general terms.

0n the top of held lates or slides 74 adjustable to and fronr e center of the opening 22 in the table, said plates being held in adjusted position by set screws 75. .The inner end of each plate 74 supports a roller 76,' the ends of which'aremolmtedin bearings on the elilids of4 arms 77 projecting upwardly from t e 77 is a brush 7 8 above the roller 7 6 and sub stanti'ally as long as said roller. Depending from each plate 74 below the arm 77 is a provided with beringsv which support a sliding frame 80, the inner end of which frame has fixed thereon a bar 81 extending at right angles to theline of movement of said frame. On leach bar 8l 'are' two sleeves 82 on each of which is 'mounted a yielding side Ilap tuck-in-finger the table 2l at the trent i and rear thereof, are `guides 73 in which are plates 74. 'Also mounted on each arm Each frame 80 with its two tuck-in depen fingers 83 is moved toward and away from threeQ-armedxlever 84 pivcted on a bracket o if!! M. th@ lill@ lltibl@ 12.4 .the center of the machine by means of a y -21 at its rear, and actuated by a cam groove 85 in a drum 86 'fixed on the vertical shaft 41 that carries the drum 42. One of the arms 84a is provided vwith a pin or roller engaging the cam-groove 85, th'e other arms 84b are connectedl .by links 86a with downwardly projecting arms 87 on cross shafts 88 one at the front andthe other at the rear of the machine. An upwardly extending arm 89 oneach shaft is connected by a link 90 one to the frame 80 at the front of the machine,

and the other to the like 'frame at the, rear ofthe machine. 1When the three-armed lever y84 .is rocked, theN frames 80 moves simultaneously to and from the center of the machine, and movable with eacli frame are the two side lap tuck-in fingers 83 mounted thereon.

On the right and left sidesof the table l are plates 91 mounted in guides 92 in a manner similar to the plates 74, and carrying at their inner ends rollers 93,-in va plane below .the rollers 76 and at right angles to said rollers. Depending from the inner ends of the plates 91 are brackets 94 similar to the brackets 79 but shorter.y In each bracket 79 and 94 vis mounted a horizontal sliding frame 95 to the inner end of which is fixed horizontal end-tuck-in fingers-96, the four fingers lying in the same horizontal plane. Just below each frame v95 is a second horif zontal sliding frame 97 each supporting on its inner end a presser `block 98 from the exterior side of -which projects a lug 99. Mounted to rock in each bracket 79, 94 adjacent the lug 99 is a rocking cam 100 to which is fixed'a short arm 101 by means of which said foam is actuated 'to advance' the frame 97 with the presser blocks 98, arl-dV through the medium of a link 102 pvoted to said arm and` to the adjacent horizontal sliding frame 95, the end-tuck.-in finger 96 107 with one ofthe short arms 101. Movement is imparted to the sleeve'103 by a cam groove 108 in the drum 86 actuating one end of a rocking lever 109 pivoted intermediate its ends upon an arm- 110 extending from the bearing support 68, the'other end of said lever being connected by a link 111 with the sleeve 103..

In the operation of the machine', the lv vorm 39 is rotated continuously and through its connection 'toj the worm wheel 40 imparts continuous rotation to the vertical shat't 41v and the cam drums 4Q and 8 6 thereon. At each. rotation ofthe drums, when they ar- 'rive at the position shown in Fig..1, a pack-V age B which in the-present instance is a box` made ot' palper board -filledf-with merchandise,'and closed with a cover thatv projects over the'box and extends to the bottom thereof.. This box with its bottom uppermost and a blank A adhering to the top of' the cover is placed by an attendant against thev `under side vof plungers 28, 50, and against the'gage plates 67, which latter exactly positipnthe box relatively to the plungers. As thus placed the flaps a1, a4, of the wrapperproject laterally from the box as shown in Figs. l, 2 and 8. Rotation of the cam\drum. 42 now causes the levers 29 and 60 to swing downwardly, simultaneously depressing the plungers and the gage fingers, the latter maintaining the box in position against said 'plungers during its passage to theplaten 71.

As soon as the box and the wrapperhave reached or nearly reached the platen, the

gage fingers 67 will pause, the plungers however continue their downward movement and press the box and wrapper against the platento hold them securely inv position against movement during their passage throughthe wrappingmechanism.' The approach of a box and its wrapper to the platen brings the tfwo'fiaps a1 of the wrapper into contact with lthe brushes 78, which turnup said flaps against corresponding sides' of the box. The plungers, box, wrapper,- and platen now move downwardly together, the flaps all previously turned up by the brushes are by the rollers 76 pressed against the' sides of'said bx into close contact therewith to causethe adhesion of said'ilaps, see

Fig. 9. "As soon as'the box and wrapper have passed belowv the rollers 76 theqdown- -ward movement is arrested momentarily,

during whichv pause the slidingframes 80 are moved inwardlywith their tuck-in finucovered' sides of the box, as in Figs. 3 and 10. Upon withdrawal 'of the frames 80, the downward movement of the box continues. The two flaps a4 now encounter the rollers 93, by means of which said flaps are turned see Fig.,11. Passing the rollers `93 the plunger, partly wrappedbox and platennow reach their lowest position, see dotted lines Eig. 1; Here the boxis gripped by the presserblocks 90 which advance simultaneously toward thebox and, pressing on th'e four sides the full,I width thereof from the upper surface oi bottom of the box a greater gers 83 to fold the side laps a2 against 'the up against the remaining vertical sides oi the-box and over the turned-1n side laps a2,

or lesser distance down therefrom, insure a firm adhesion of the wrapper flapsto the box walls.. Afterpassing threlower rollers 93 manana l but before arriving at the lowermost position the 'downward movement of the plunger ing the tuck-in ingers96 and the frames 97 with the presser blocks 98, toward the bon,

is arrested, the smaller plunger 28 however, continues to push the b ox and platen down, the plunger holding the box on the platen against the tension of the spring 72. The stoppage of the plunger 20 is for an instant only and is brought about. by the lever which has previously moved upward av predetermined distance and there held duringthe downward movement of the plunger. At the proper time, the pin 63 on the cross head 48 encounters the plate 62 on said lever 60 and preventsurther movement ot the plunger 50 so long as the lever 60 continues in a fixed position, see Fig. d. rl`he stoppage of the plunger 50 is 'to permit the end laps a, 0L5 of the wrapper to be folded over the ,upper surface or bottom ot the box B. This `folding is accomplished by means of the endtuck-in fingers 96, alll tour of which move inwardly at the saine time when the sleeve 103 is' elevated by the cam drum 86 and lever 109. lWhen said sleeve is lifted it raises the pins 106, and-through the connections heretotore described, slide thefraines carryturning the end flaps thereover and grippin'g the box. For the purpose ot insuring the proper folding of the end laps a3, a5, it is ,desirable that two of them, as a5, be turned before the other two a3, so that the latter mayoverlie the former as in lFig. 111. This will prevent interference ot the laps and secure a smooth tight sealing at all times. 'lo cause the earlier folding ot two ot said laps the tuck-in lingers 96' which operate thereon may bemade wider so as to engage said laps sooner, or the short arms 101 by which they are advanced may have a diderent leverage in order' to advance earlier. After the tuck-in lingers have turned the end Haps a3, a?, over the upper surface or fbottomof'thebox, see Fig. 12,.they stop torA an instant during which arrest the lever 60 again descends, thus releasing the pin 63 and the plunger 50, which latter through its weight and the tension of spring 52 drops upon the ngers 96, seelig. 13. alter which saidingers withdraw, permitting the plunger 50 to descend uponthe endl laps and press them against the upper surface ot theV box, sealing them tightly thereto and covering thespace between the-box and the edge of its closure. rl`he presser blocks'nowv re lease the box, the plungers are raised by the upward movement of lever 29, and the seal.

wrapped box is lifted by the plunger through the tension ofthe' spring 72 into position to be immediately' discharged onto a run-way 112. y

'lhe wrapped packages may' 'herernoted from the platen 71 manually, or by a pusher 113 operated automatically by verteerd `slide in a bearing 116 on the standard 23.V

@n one side of the rod is a rack 117 with which engages a gear wheel 118 turning ou'ashort upright shaft A119 hired at its lower end in a bracket, 'and surrounded by a coiled spring 120, one end of which is at tached to the shaft support and the other end to a. pinion 121 rotatable with the gear wheel 11d. 'llhe pinion 121 is driven by al gear wheel 122, on one side oli which is a pinion 123 with which a short toothed segment 121 mountedqon the vertical shatt l1 123, reacts and returns ithe plunger head 11e f Wto its inactive position, the shock ot the quick return being prevented by a dash pot 125 into which the head 11d enters. lnY order that the pinion 123 may always be in position tor the segment 12d to engage therewith without the respective teeth clashing, a. positive stop is provided to .insure the return of the plunger always to the same position. rll`his stop is in the torna ot a pawl 126 pivoted to a fixed part ot the Atrame and held by a spring against the plunger rod 115, a tooth 127 on said pawl engaging a notch 128 in the rod when the pusherfhead 1141 has been retracted by the spring into its rearmost position.

Yllhe pusher head moves slowly for the purpose ot ejecting the sealed wrapped package, as distinguished from known types ol spring impelled or shooting plungers, such movement being desirable because the bon or other envelop is a hlled bos and has more or less weight, depending on the nature ot its contents, and` therefore the iner tia of this weighted package must be overcome by a comparatively slow movement ot the eiector, otherwise the latter it moved rapidly is liable to break through the wall ot the package and spoil the same. 'lhe return movement ol the pusher head may be as rapid fas desired and tor this reason-the reo spring 120 is provided as a simple, e`tli eient,

and rapid motor tor-, retracting the pusher. The piangere; 28jf`a7nd 50 together have three unetions inthe-operation ot' the maoil 'which `ie to slamp tho les wrapped package, the combination withv package-and wrapper upon the platen and hold it`thereon during its passage through the Wrapper applying mechanism; the second is -to push -the package and the platen through said mechanism, and the third is to assist certain devices to fold and seal the end laps of the wrapper over the upper surface of' the, package, the last function being performed by the plunger 50 while the plunger 28 maintains the package in position. plunger are substantially the same as the upper surface of the package so as to bear. upon the inturned laps of the wrapper, while the plunger. 28 though suiiiciently large to bear upon said upper surface of the package, and hold the same stationary against the tension of the spring 72- without breaking through the package, during the separation of the plungers, is small to permit the end laps of the wrapper being turned in and sealed without coming into contact with said plunger.
