Original application filed June 2, 1920f$eria1 No. 386,023. *Divided. and this application filedfiune 5,
1922." Serial To all whom it may Concern.
it known that I, FRANK VV'. Lnv a citizen of the United States, residing at New v York city, inthe county of New York and ofSta-te of New York, have invented certain new and useful Improvements in a Feeding D eviee'tor lVrapping Machines, of which the following is aspecification.
This invention relatesugenerallyto maclnnery vtor wrapping packages 01' cigarettes andthedike and refers particularly to a teeding device by means of which wrappers or labels may be fed singly and SUCCGSSIVQlY from the bottom of ansuperposedpile and wrapped.
The present my co-pending 7 386,023, filediJune 2, 1920.
application is a The, principal objects of the invention are p to providenn improved mechanlsm of this with a ratchet and pawl device to intermit-.
tently advance a series of feeding-out conveyors in one direction only.
The invention is lowing specification and clearly set forth in the appended claims, and illustratively exemplified in the accompanying which Figure 1 is a top plan view of a wrapping machine showing the wrapper magazine and feeding-out conveyors; Figure 2 is an end elevational view ofthc mag-(v zine looking towards the feed mechanism and showing parts broken away to more clearly disclose the adjustable wrapper support at the delivery end of the wrapper teed; Figure 3 is a,sideelevational 'viewof .the magazine and feeding-out conveyor mechanism, parts being broken away toshow otherwise hidden mechanism; Figure 1 1s a broken side elevational' viewof the wrapper magazine; Figure 5 is a section'alview of the wrapper magazine and feeding-out conveyor on the lines;5-5 of Figure 4; and Figure 6 is a perspective view of a portion delivered at astation in the machine forsubw sequent folding about a bundle to be v v division of appl cation, Serial No.
I v folders 14: designed to turn in the overhangtully described in the foldrawings, 1n 7 boxes to" and past the different generally of a suitable Gencva 'nism operated through a gear train trom is ejected from m ditional folding instruments and delivered of the magazine supporting members showing the adjustable registeringarrangement.
f In Figure l of the drawing I have illustrated the general assemblyof a, wrapping machine substantially in accordance with my said priorapplication, such assembly consistingof a combination of related elements, by means of which articles such as Cigarettes or thelike are first bundled and thereafter each bundle is wrapped in a single cover or label.
:The articles to be wrapped inthis case cigarettes, are contained in a hopper A of any approved form, from. which two rows of cigarettesare ejected and subsequently arranged bynreans of well. known mechaansm nto a bundle 10, as indlcated in dotted lines injFigure 6.
The bundle thus formed. while held between guides; not-sh0vvn, is engaged by a plunger and advanced against a previously pos tioned wrapper 12. Continued movement of the plunger 11 and bundle 10 causes the wrapper to double over the forward end of the bundle and to carry the doubled wrapper into one ofa series of folding boxes 13.
' hefolding compartments mounted on an endless boxes consist of open ended con- veyor carrier B. and positioned to receive the packages advanced by the plunger. The compartments f are provided with corner ing portions of thedonblewrapper 12, as a preliminary step in completing the closure of the bundle 10.
The carrier or endless conveyor Bv is intermittently advanced to carry the folding folding in struments, by means of whichthe sides of the wrapper are folded intorp'lace. The
mechanismfor operating thefconreyor B but consists is not shown in the drawings;

from the machine at C.
Referring particularly to the magazine and feeding mechanism, shown in Figures 2 to 5 inclusive, 16 denotes a magazine from which the wrapper or labels are automatically fed by means of a feeding-out conveyor mechanism 17. The magazine comprises two parallel longitudinal walls 18 having downwardly projecting portions 19 at their delivery ends secured to the bed of the machine proper. The walls 18 are separated from each other the width of a wrapper 12 and at their opposite ends are secured to end walls 20. The rectangular frame thus formed is provided with a bottom plate 21 having a cut-out portion 22 adjacent the delivery end of the walls. Secured at their lower ends to the upper edges of the walls 18 and 20 are a plurality of upstanding guide pins 23, the opposite free ends of which project well above the walls so as to receive and support a pile of wrappers 12, shown particularly in Figures 3 and 5. The cut-out portion 22 of the bottom wall 21 extends well into the interior of the plate and is provided to receive the upper runs of a plurality of feeding-out friction belts 24, the said upper runs being on a plane slightly above the upper face of the plate, so as to engage the lowermost wrapper in the magazine. The belts 24 are supported on pulleys 25 which are carried by shafts 26 mounted in the opposite walls 18 and an intermittent feeding operation is provided by intermittently rotating these shafts in a feeding-out direction, i. e. towards the delivery end of the device.
This intermittent feeding movement is imparted to the shafts 26 from a reriproeating rack 27 slidably mounted in guides 28 on the outer face of one of the side walls 18 of the magazine and engaging with gears 29 carried by sleeves 30 loosely mounted on the shafts 26. The sleeves 30 are further provided with flanged disks 31, supporting spring pressed pawls 32 in engagement with ratohets 33 keyed to the ends of the shafts 26. The pawl and ratchet mechanism just referred to is arranged with respect to the pulleys 25 so as to operate the conveyor shafts 26 only in one direction, i. e. the feeding-out direction or toward the right in. Figure 4.
The wrappers as they are separated from the pile by the conveyor belts 24 are advanced by the latter to engage with a plurality of vertically disposed conveyor belts 34 supported at their upper portions by suitable pulleys 35, the latter being provided with hearing pins 36 journaled in the op posite walls 18. These conveyor belts 34 comprise two parallel sections, the outermost of which extends substantially above the horizontal plane at which the wrappers are advanced by the conveyor belts 24, so as to receive the said wrapper 12 and turn its forward end in a downwardly direction. The second section has its uppermost pulleys 35 disposed on a plane below the level of the path over which the advancing wrapper traverses, and as the belts of the two sections travel in opposite directions the wrapper having engaged the outermost belt is first led downwardly and then between the belts of the two sections. The belts of the vertical conveyors 34 may be constantly driven and extend down far enough to drop the wrappers accurately in a pair of guide channels 37 which project towards each other from the opposite faces of the projecting portions 19 of the walls 18, as shown in Figure 6. The lower ends of the guide channels 37 are provided with longitudinal slots 38 adapted to receive stop pins 39, the latter being adjustable therein and mounted in plates 40. The plates 40 are adjustably held closely adjacent the outside faces of the channel pieces 37 and are provided with slots 41 at their lower ends to receive the stems of thumb screws 42 adjustable in and carried by the channel guides 37.
Power is imparted to the feed belts 24 and 34 through a constantly driven train of gears 43 which receit e their power from shaft 44 through bevel gearing 45 and an upright shaft 46 connected by gearing with the main drive or power shaft 15. In the drawings I have illustrated this constant drive as being utilized to effect the reciprocating movement of the feeding-out rack 27; the connections for this purpose, as best shown in Figures 3 and 4, comprising a crank disk 47 driven by gears 48 from the upper pulley for the outermost section of the conveyors 34 and connected by a pivoted link 49 with the end of the rack 27. Vith this construction the rack 27 is continually reciprocated back and forth and through the rack andpawl arrangement previously described, the connection thus made will operate the wrapper-separating and feedingout devices only on the outward strokes of the rack.
The wrappers, after having descended with the bolts 34 are released and fall between the channel guides 37 wherethey are supported in upright position. They are then registered in front of the pockets of the folding boxes 13 by engagement with the adjustable stop pins The adjustability of these registeringdevices enables the feeding section of the machine to be adapted to different sizes or styles of wrappers or labels and the independent flCllU5t- 'ment of the two stops performs the impor tant function of permitting the wrappers to be tilted if necessary before being doubled about the packages so as to produce any desired effect.
Having fully described the several parts of my invention and set forth their general operation what I claim and desire to secure by Letters Patent is:
In a mechanism forfeeding individual blanks from a pile of blanks in the magazine of a wrapping machine, the combination with parallel shafts disposed transversely of said magazine and adjacent opposite ends thereof, a plurality of closely spaced pulleys fixed to said shafts, separator belts, said belts presenting a plurality of closely spaced independent supporting surfaces for said pulleys at the bottom of the magazin to receive the pile of blanks and to separate the lowermost blank from the pile, a toothed rack slidably mounted longitudinally of said magazine, a pawl and ratchet mechanism for each shaft for permitting rotation in one direction only, a pinion carried by each ratchet mechanism and in constant mesh with the teeth of said rack, and a reciprocating pitman connection pivotally connected at one end to said rack for intermittently advancing the conveyor.
In testimony whereof I aifix my signature. FRANK V. LEV.
