Beit known that l, CESARE lBarselaar, a' citizen of the -United States, residing at `My 'nvention relates to a method of and apparatus forV forming tapered orv conlcal. drinking cups and receptacles frompaper or like substances.
Some of the methods and maghinegy' ndwlflanknl'huyfarthef cupfhasA-lnfco fir* ise'lnng A1this type of receptacle form the blank into its inal'shape or conical form during the formative stages previous to the completion of the receptacle. This involves complicated mechanism for so doing, varying according to the original shape of the blank from which the cup is formed, and' generally requires a lar e blank to provide a wide space for the ahesive in order to obtain an instantaneous of the cup before place.
Heretofore it` has been the practice to form the cups or receptacles from paper previously vprepared with paraiiin` or wax, using the paraffin as the adhesive agent. Since the adhesive properties of the paran Ais limited and' easily eHected by tem erature, a larger blank was required 1n or er to propaper to fold several times about the blank. A
para n or wax it after formation, but the process has been found slow and expensive.
ln the invention herein'set forth, I have obviated among others the objections above pointed out in providing a method which involves several simple steps b which the v original blank is folded, seale and waterproofed, each ste contemplating a Working v ofthe blank -whi e ilat.
" 4rl`he v invention herein disclosed contem-l plates an economical use of the material from which the cupis formed aswell as a saving of timeduringfthe' formation of the l cups, both of which are important factors Attempts have been made to form a conaper cup from plain paper and tov .the machine.
in this class of invention in the commercial field.
The method contemplates the several steps by whicha blank is cut, or previously cut b ank is formed into the linished article and broadly consists in. obtaining a blank substantially in the form of a development of a cone, appl ing an adhesive to one edge thereof and o ding substantially ual of the blank one upon the ot er, the folddblankfto form a sealing strip,
-applying an adhesive to the sealing strip sealing the strip upon the blank, andapplyl ing a' waterproong agency to the ,formed petely formed in collapsed'iorm and may packed for shipment after drying or 1t..
may be opened to conical Aform to permit the drying-or partial drying 'of the Wateragncy. rlhe cup is thus completed of s ace and ease of packin pgrtions A ndmg packed in its conical form 'by .l
- 'll e apparatus by which 'ie several steps are accomplished comprises broadly several instrumentalities, 4 operating automatically and in a predetermined order and time,
' which receive a cutblank, or by preference cnt a blank from a supply of paper or like material, and feed the blank throughv the machine in a substantiall horizontal plane. During the pro ssion o the blank through the machine, t e several steps herein referred to are acpplished, the blank remaining'at durin thefwhile.. After the completion or fina forming ofthe {blank} it may be delivered from the machine while flat or presented to a mechanism which op erates to open the blank to a tapered or conical form, and delivers it for removal from 'elevation ofthe appa-4 removed Fig. 5 is an end view Yshowin. themechanism for opening the complete :blank .into

A hollow frame 1 lsubstantially rectangulai.` in shape forms the bed or base of the machine and by preference supports at oneend the material feeding and blank cutting mechanism. The material feeding is accom-v plished by carryingY a supply of material 2 preferably vin roll form upon a shaft 3, inbrackets 4 mounted onthe .frame 1 of the machine. The free end of the paper or material is carried upwardly and over a roller osition the blank assumes at the time of d ivery to the bend- 'able manner, the roller '7 being preferably under the pressure of suitable springs 10 to produce a proper tension upon the paper or material.
The paper is automatically and intermittently fed forward between the rolls 7 and 8, t'o the die or blank cutting mechanism hereafter described, and is accomplished by providing each of the rolls 7 and 8 with a gear 12. The gears 12 mesh and when rotated serve to revolve the rolls'in opposite directions. A 8 and mes es with a gear 15 rotatably secured to a ystud 16 on the frame 1. This gear 15 is intermittently moved throu h a artial revolution by means of a dog 1 whlch engages at times the teeth'of the gear and rotates the same. -The dog 17 is pivoted to a bell crank 18, movable onthe stud 16, and is so constructed that upon a movement in one direction it will engage the teeth of the gear 15 and revolve the same, and when moved in the opposite direction will bev disengaged from the teeth of the gear 15, and cease the rotation thereof. The bell-crank 18 land the dog 17 is oscillated by means of the link 20 connected by a pin 21 to a crank plate 22 fast to the continuously revolving drive-shaft 23.
The paper or material after passing l through the rolls 7 and 8 moves on to the die or blank cutting device where individual blanks are eriodically cut from the paper stock to substantially the shape shown in Figs. 7 and.v 22. The blank cutting device is of the usual type, one of the cutting members 24 being carried and raised and lowered b posts 25, slidabl mounted-in the frame 1.
e osts 25 at t eir lower ends are connecte by the crosshead 26 carrying a pin 27 to which is connected,y intermediate its ends, a lever 28 pivoted at one end as at 30 to a bracket on the main frame 1. 'Phe opposite end of the lever 28 carries a roller 31 which engages with and is periodically raised and ear 14 is connected to the roller and frame 1 acts to hold the roller 31 in coutact with the cam 32. i The stationary 'cutting member or anvil 34 of the blank cutting mechanism which is supported on the main frame 1 is transversely lbifurcatedas at 35 for the reception of the material Vand isl provided with an openin 36 in which themem- -ber 24 moves upward y and downwardly.
where it may readily receive the blank, see Figs.. 3, 16 and 17. 'A positive discharge of the blank from the blank cutting mechanism may be accomplished by providing the movable member 24 with a plunger 38 and operati f mechanism as shown in Figs.
16 and 17. e plunger 38 is located -within a recess in the bottom .of the memberV .24 when that ,memberis. in its uppermost l@ or raised position, see Fig. 17, and vis provided with an u wardly` projecting stem 41 which '.slides. 1n lthe member 24. 'The member 24 is provided with' a recess 42 in which'is located a portion of an Vexpansion i5 spring 43, the upper end of -which bears l against a collar 44 fast to the stem 41. Y The upper' end of the stem .41 is provided with a pin 45 which is engaged bythe slotted end -46 of alever 47 pivoted intermediate its ends as at 48 to a bracketv50 carried by the member @24. The end 51 of thelever 47 is en- `gaged at the pro er `time byv an adjustable .screw 52 carried' y the post 53 fast to the stationary member 34 onthe frame 1. The arrangement of the parts is such that immediately fglolviing*thecgittjnfg;of thegblank *"byftledown a mvementblnmbr 24, the end 51 of the lever. 47 vWill engagevthe screw 52 and operate the' plunger 38 to discharge the blank upon-the `support 3 7, see Fig. 16. Upon the .upward movement of the' member 24 the spring 43 acts to seat the plunger. in the recess 40. Accurate timing'of .the .operation of the plunger may be had by 55 adjusting the screw 52.
y 5 After the'cutting of the blank the surplus pa' er may be removed from the machine by `ro ers 53 and 54 which are located adjacent the -forward ,end of lthe blank cutting mechanism and extend transversely of the machine. The roller 53 is journaled in suitable bearingssu ported by the. main frame 1 and is rotated a sprocket wheel 55 connected thereto, w 'ch' is driven through a rugated .to` permit the blank to lie flat upon' the plate and, has one-of its edges 62 arranged at an angle to they other edges as shown in Figs. 4 and 7.' A shoulder`63 may be formed on the support to. assist inv maintaini the blank in pro erjposition thereon. The b ank 39 is' receive from the die-by the supporting plate in the position shown-.in Fig. 7 and' substantially one-'half ofl the blank projecting*beyondv the edge 62 of the' carrier 37 and out of contact with the plate. lt will be here noted (that it is not neceschain 56 by a sprocket wheel 57 connected to the roller 8. rlhe roller 54 has each'endsary that thepaper vor material be fed 'incassi and ecut into the desired blanks by mechanism forming a part of thisapparatus, although I have shown and described such a .mechanism Suitable blanks maybe cut and fed to the support 37 by'automatic de` vices independently of this apparatus'or prethe plate 37.v`
Following tho positioning oficio blookss upon the support vor carrier37 inthe manner just described, .the plate is moved for` gluing lwheel 65,' receiving alcoating of ad. hes'ive. The support 37 is fast to a slide 66 which is` guided and reciprocated horizonviously -cut blanksm'ay be fed by hand toy wardly (or to the left inv Fig.. 4) and a nartally in the mainframe 1.' To reciprocate. the slide oneend oa link. 67 isattached thereto as atv 68 and the other. end is pivotally connected as at 70 to one end.; of a lever 71', the 'op ositel end of which is pivoted as at 72 to t e main frame 1. Onej'end'of a p, itman 73 is pivoted'to the. lever' 71 asY at 7 i in which worksthe crank pin76`on the crank Aplate `77 fast ion thedriveshaft 23.
Thel slot'7 5 is elongated as-shown', in dotted4 .lines in Figure -1 so that-whenjthe slide is at the' extreme limit of its movement in both directions a period of rest will occur, pro-l vidingfsuliicient time for the" bending and folding element, hereinafter described, `to
operate. j
Subsequent t'o the gluing ofthe portion 39a the blank is moved further forward by lthe plate 37 and is transferred'to the plate or bed 78' fast to the frame 1. This is accomp-lished by a linger 80 which is raised slightly above the horizontal plane of the carrier 37 during its forward ltravel and is .lowered immediately in the rearA of the s4 and the other endis providedfwith. a` slot 5 blank upon the carrier after the latter has 'l come to rest and over the bed 7.8.' Upon thev return movement of the support 37 yto its blank and remove it from the carrier whereinitial positiontheinger acts to hold the.
i io
upon it is deposited on or transferred to the. i
. bed'v 78.- The finger 80 is fast to a transverse shaft '81 carried in suitable brackets 82 on the frame 1 and is raised by 'an arm 83,. one end of which is fast to the shaft 81 andthe of a lever 85, pivoted'intermediaterits .ends as at .86"to .the main frame, and the opposite end of the. lever carries a. roller'87 which is engaged `at the proper. time by a cam 88 revo vm 87 is eld to contact with the cam 88, and the linger V8O is normally depressed by the retractile s ring89. The bed 8 is provided with an angularly disposed edg 90 which is parallel with and -at times in a 'gnmexit with the edge 62 of the other end of which is connected to a vertical link 84. This link is connectedto one'end lao with the-drive shaft 23.l The roller support 37. A forming plate 91 is fast to and consequently reciprocates with the lslide 66 and is substantially the same shape as the bed 78, and has an angularly disposed edge 92, corresponding with the edge 90 of the bed 78. The longitudinal position of the :plaie 91 upon the slide 66 is such'that whenthe support is 'at its rearmost or blank receiving position, the plate 91 will beabo've and in` alignment but out of contactwith the bed 78, see Figs. 3 and 8. Aftervthe transfer of the blank'39 tothe bed 78 the support. 37 retreats to its original position to receive a new blank, where it will remain stationary for a short time owing to the slot and pin connection' 75-76 which producesl a lost motion of the mechanism.
Immediately after the forming plate 91 assumes its position in alignment with the bed 78, the blank is bent upwardly parallel with and along the edges 92 of the platev 91, see Figs. 3, 9 and 12. This isaccomplished by a bending and folding clement which consists of a bar 93 arranged across the path of travel of the blank and having its major portion closely approaching and parallel to the edge 92 of the forming plate 91. The bar 93 vis carried by the slide 59 which works in a guide on the frame 1, and receives a vertical reciprocating motion by means of the roller 69 on the slide working on a cam 79 fast to the drive shaft 23. The shape of the cam 79 is such that at the time 'the blank is deposited upon the bed 78 the bar 93 is at its lowermost position, a portion of the blank projecting beyondr the bed 78 and over the bar 93, see Figs. 8 and 11. transverse slot 95 is formed in the bar 93, see Figs. 3 and 10, and extends substantially throughout. its length..k This slot is so located and theshape of the cam79 is such 'that when the bar 93 is raised to bend the blank the slot 95 will'come to restfor a short interval in --alignment with vand adjacent the forming plate 91. The depth of the slot is such that the forming plate and the blank will readily pass therethrough as hereafter described. v
Following the positioning of the parts as shown in Figs. 3, 9 and 12 the blank is moved forward by the plate 91 through the slot 95 in the bar 93 and isbent substantially upon itself with the plate 91 between theformedhalves of the blank, the edge 39b of the blank contacting with and being sealed to the narrow portion 39 previously glued by the wheel 65, see Fig. 24.
u As the blank upon the forming plate 91 emerges from the slot 95, the sealed edges- 39e-39b andnow termed the sealing strip or portion 39, is engaged by suitable fingers 96 on the bar`93 which bend .the sealed strip 39c upwardly and at right angles to the remainder of the blank.-V After engagement. with the fingers 96, the strip 39 receives tassa a coatin of glue or proper adhesive from the whee 97.
Further forward movement of the forming plate 91 brings the sealed strip 39c of the blank beneath the beveled edge 98 of an arm 100, carried by the main frame 1, whereupon the sealing strip or portion is folded' upon and in contact with the body of the blank and sealed thereto, see Figs. 14 and. 26, the strip 39c having been previously glued by the wheel 97 as before described.
The forming plate 91 with the blank thereon continues its forward movementand comes to rest for a short time at the position shown in Fig. 15. As the forming plate 91 comes to rest, fingers 101 and 102 are lowered behind the blank 39 on the forming plate, and acts to remove the blank from the forming plate, upon its rearward or return movement', and transfer or deposit it upon plate 103 carried on the frame 1 of the machine. The lingers 101 and 102 are fast to a transverse shaft 104 carried in brackets 105 on the frame 1, and are operated by an varm 106 fast to the shaft 104. The arm 106 is connected by a link 107 and arm 108 to the shaft 81 previously described. Since the fingers 80 and 101 and 102 are connected by virtue of the link 107, it is ap-v parent that they will be actuated as a unit or together by the spring 8,9, cam 88, roller 87, lever 85, link 84, etc., as hereinbefore described. t
lt will be here noticed, see Fi 26, that as a result of the folding and seang of the .strip 59 that a portion 39d of the stri 39 projects slightly beyond the apex o the blank. Thisportion 39d is bent along the edge 39 of the blank following its transfer to the plate 103, by a finger 110 on one end of a lever 111 pivoted'intermediate its ends as at 112 and sup orted by the main frame 1. The opposite enti) of the lever contacts with a shoulder 113 formed on the bar 93,*and is loperated upon the raising and lowering of the slide 59 and its operating mechanism hereinbefore described. The upward movement of the slide through the shoulder 113 and lever 111 acts to de ress the finger 110 and upon the lowering o the slide the finger is raised through the retractile s which serves to hold the lever 111 1n contact with the shoulder 113. spring 114 may be attached to the lever-111 and the other end may be attached to a reservoir 127 as shown inFig. 3.
Following the bending of the portion 39 by the :linger 110 the blank is again moved forwardly and presented to-the rolls 115 and 116 hereinafter described. To accomplish this a feed roll 120 is adapted to contact at times with the blank and move it forwardly. The feed roll 120 is fast to a tatably carried in one end of an arm 117, the opposite end of y'which shaft 118, ro-` is supported One end of the on a transverse shaft 121.'- The end of the arm 117' carryingvthe-shaft 118 is provided with a split lug 122 and receives a screw 123 a which -isadapted to vcontact'vwith and be the proper transfer of the blank fro kdraw the rol raised and lowered bythe lever 111 hereinbefore described. 'The adjustment of the,
screw -123 should be such that when the finger 110 is raised the arm 117 and roll 120 thereon will be raised suiliciently to dnit t e forming plate 91 to the'plate 103 and when the finger islo'wered and bends the portion 39d ofi the blank as hereinbefore described, the roll 120 will lower into contact with the blank, see Fi 3. 'A spring 119 tends to 120 into contact with the blank. The roll 120- is rotated by means Vof a sprocket wheel-124 fasten the shaft 118 i, roll 120 during whichtime the ortion 39d of? which is driven'through the chain 125 by a,
sprocket wheel 126 on the shaft 121.
The blank havingl been fed forward by the the blank will have been folde 'into contact with the blank now passes between they horizontal rolls 115f and 116 and receives a coating of water-proofing material such as hot will bepressed and impregnated wit parain, wax, orl the like,l 'from the roller 116 vwhich is partially submerged in androtates in a reservoir-127 forthe waterproong mafteriaL The, reservoir is provided at its bottom"with a chamber 128 into which. a heating medium (hot water, steam, vheated gases or the like) maybe directed to maintain the'- waterproong'material in aheated'and liq- `uid condition.Y The roll 115 4is preferably under suitable spring' pressure so that the blank, when passing through the rollers 115 and 116 will not only be fed forwardl ,blilit t e waterproofing material, thereby ensuring a' water roof rece tacle. Any. improper seal- 'ing o `the glue portions ofthe blank will be minimizedif not-wholly'eliminated by fthe 'assa e'of the blank between the rolls.
e rol s 115 and 116 are rotated by means of a sprocket wheelyl, fast` on the drive shaft 23, which rotates b means of the chain 131, a toothed whee 132, connected to one endof the roll 1161 The opposite end of the roll 116 isconnected lto gear 133 which meshes with and drives a gear 134 fast to the shaft 121 on wliichthe vnpper roller 115 is carried.'
The -referre (gluing wheels and to operate in conjunction withand are fed' in an suitable manner by the reservoirs, 135 'an' `136, and are rotated by the shafts 137, 138, journaled in bearings on the frame 1. Thelshafts' 137 and v138 l are provided at k'their endswith sprocket wheels140,
141,l ,which are-connected -by the chain 142.
The shaft 1 38 'is provided with' e. secondv s rocket Wheel-143 which is drivenb'through t chain 144;.by ,a sprocket wheel 145 fast onV one end of a stub shaft 146 journaled. in'
Maasai 97 previously bearings on the frame 1Q A gear 147 fast on the opposite end of the shaft 146 meshes with and is driven by'a pinion 148 mounted.
for Irotation with the gear 133 and about the same axis.
After the blank is waterproofed and pressed it may be delivered from the ma chine in flat form or opened for final sha ing of the cup to prevent the adhesion of t e contacting sides of the ilat blank and for drying. in the latter case after the dat blank passes from between the rollers 115 and 116, it slides down the inclined plate or chute 15() and comes to rest in a vertical positionbetween the horizontal pins 151, be-` neath a conical former 155,. and over the rollers 152, see Figs.3and 5. The'pins 151` are carried in the upper horizontal bar 153 of. a, cross-head 154 andthe rollers 152 are secured to the upper ends of corresponding levers 156, norma 'drawn toward one another by the spring 157, and pivotally secured to a lower horizontal vbar 158 of the cross-head 154. i
. Followingthe deliveryof the flat blank to ins 151'the blank is-then opened to conical vorni for sha ing and drying. To this end the formed Il) formerv 15,5, carried by the `frame 1, byy the cross-head 154 which is slidably, mounted upon' the vertical standards 160, carried in brackets by the frame 1. with the formed blank thereon is raised and lowered by adink 161, one end of which is pivoted' as at 162 to the lower horizontal bar of which is'pivotally connected as at 163 to the arm 164 'of a bell crank 165.

be delivered to a conveyor or other suitable .mechanism for removing them from the. ma-
chine. A s y The bell-crank 165is pivotally mounted vas at 167 to'the frame 1 and its a'rm 168 projects upwardly 'and carries the roller 170 which contacts -with the cam 171 fast on the ydrive shaft 23. The shape of the cam 100 158 of the cross-head`154 and the other end 7 blank, folding t 171 should be such that when a blank has -been received by the pins 151 the cross-head will be raised gradually then quickly lowered to remove the blank or cup from the former and maintained in its lower position to await the receipt of the next blank from the rolls 115 and 116. The Weight of the cross-head 154 through the link 161' and bell-crank 165 holds the caln roller 170 against theI cam 171 and this weight may be partially counterbalanced by the Weight 172 carried by the bell-crank to one side' of its pivot 167.
The shaft 23 is continuously driven and this may be accomplished by the gear 173 fast thereon Which meshes with the pinion 174 fast o n a shaft 175 driven by an electric motor 176 or any other suitable means.
