To all whomz't may concern:

Be it known that I,-E ow1n T. GREENFIELD, a citizen of the United States, and resident of Kiamesha, in the county of Sullivan and State of New York, have made a new and useful Invention in the Art of Manufacturing Paper Bottles orContaining Vessels, of which the followingis a specification.

My intention is directed to a novel method of manufacturing or constructing bottles or containing vessels for liquids generally, but part-icularlyfordairy products, as milk, cream, etc., and it has for its object,

to'construct-such a bottle or containing vesfisel from fibrous'materlal, such as paper, and in such-manner as to produce a bottle of great strength, minimum lightness and at-a minimum cost.

My invention contemplates especially the manufacture -of a bottle as disclosed in Unigd. States Patent No. 940,310, gra

to me Nov. 16th, 1909, which bottle is made from a tube of paper and is of such a nature that the throat and neck of the article possess great strength thereby adapting it to 'be'handled when being filled or transported illustrated and described a bot-tle.having the body portion of tubular -form and a 'fromplace' to place, as ordinary glass botties are handled, without damage or injury thereto. I

I In' the before-mentioned patent I have throat decreasing in diameter from the shoulder thereof to the neck which is of cylindrical .form, said throat and neck being provided with ribs in the nature of tapering box plaits giving thereto greater strength as the ,p'laits' approach the neck and mouth of the' bottle proper, said bottle being also provided with a cup bottom and a mouth ring of. like material, which parts are secured respectively to the bot-tomof the body and the mouth of the bottle proper by a concentric'bead, so that the entire bottle when completed resembles very closely existing types of glass bottles as to conformation or shape and possesses the qualification of being-equally. strong at the parts by which it is handled during. the'p'rocess of filling and in transportation.

In the present apphoatyongl have disclosed mechanism for constructing this bottle and. I will now describe the method of making it, through the agency of such mechanism,

reference beinghad to the accompanying rarefi d Feb. 6,1912.

structing the before-mentioned bottle,,illustrating" also the paper tube in position prepara tory to performing the method of shap-. mg the throat and neck of the bottle proper Fig. 2 is a plan 1 from the top drawings,

throat and forced into lines Fig. 1, this figure not being seen in Fig. 1. Fig. 3 1s a vertical sectional view taken through view as seen looking at .Fig.

upon the assumption that the neck forming parts have been the position shown .in dotted Fig. :2 on the line X- X, the two positions of the clamping-ring and clamping wedges toward the bottom ot the the clamping ring shown in" for use therewith being shown respectively in full lines and dotted lines; perspective view of the double ori duplex forming arms which the bottle, and then the turning down of the folds of the surplus material so as to form- -ribs or plaits which give increased strength to thosepart's. ,'F1g. 5 1s a plan view of the Fig. 4: is a successively effect the -f0l11121t10l1 ofthe throat and neck proper of a beading tool for securing thebottomof the part thereof, a similar tool of smaller di; mensions being provided, for performing bottle proper to the interior of the bottom the like function with relation to the mouth ring at the upper end of the neck of the bottle; a sectional view of the body of the bottle being shown in position while the act-ion of securing thebottom thereto is being eff fected; Fig. 6 is a sectional view taken through Fig. 5 and as seen looking thereat from the bottom toward the top of the drawings in the direction of the arrows,

butupon. the assumption that the operating beading lever is removed to its outer or inoperative a position; this view illustrating also the bottom ofthe bottle proper and the manner in'= which it is secured to the body thereof, to

gether with the means for detachably securmg it to a bench or table. Fig. 7 is a sectional view of the neck 'and' mouth of the completed bottle, which the mouth proper by a heading tool like that show'nin Figs-5 and 6.

' Referring now to the .drawings in detail illustratingthe manner in ring is secured to the neck I 10 and first to Figs. 1 to 4 inclusive, 1, 2 and. 3

represent respectively the body part, the throat part and the neck part of an interior forming mold having the eonforn'lation or shape of the interior of the bottle to be constructed, said .mold being two part in effect;

that is to say, split in the direction of its length to apoint approximating the neck' thereof so that the 'same may be spread at its bottom. 4 represents a tube made of paper or other fibrous material and having substantially the interior diameter of the exterior of the body part 1 of the mold. 5 represents the base or supporting part of the mold and 6 a wedge adapted to spread the bottom of the body part 1 thereof. 7, 7,

represent a plurality of forming arms which are provided at their bottoms with dowel pins 8,. 8, adapted to fit loosely in radially disposed holes in the base 5, there being two of these dowel pins and corresponding holes for each arm. These arms are curvilinear in cross section at the various parts of the .length thereofto conform to the exterior .curvilinearjsurface of the completed bottle.

9, 9, are curvilinear parts secured to the forming arms 7, 7, by screws, as shown and the structural arrangement of all of these interconnected parts is such that when in closed-position about the mold 1, 2 and 3,

they fitl'snuglyagainst the faces of all of the" parts thereof, as will be apparent on inspection ofFigsJl and 2. 10, 10 constitute similar curvilinear forming arms designedto complete the folding down of the ri s or box plaits after the first-named arms 7, 7 and the curvilinear-parts 9,.9 have, been.

drawn forward in the. manner shown in Fig. 2; 11, 11 are pins' pivotally securing the arms 1O, 10 to the arms 7, 7, each pair of arms 7, 10, thus constituting in effectone set of duplexforming arms. 12 is a clamping ring designedto apply the proper pressure to the upper ends of the arms 7, 7, during the first step of the method of the conformation of the bottle proper, and 13, 13 are hedges designed to complete the final step of the forming'method by forcing the curvilinear forming arms 10, 10 into their ultimate position, as will be described in conneetion with the mode of operation.

Referring now to Figs. and 6, I will describe the apparatus for completing the bot-- tle by securing the cup like bottom to thebottom of the body part of the bottle, and

.also for securing the mouthri-ng to the 16 represents the tube from which the bottle is to be constructed. 21 represents the male part of the bead forming tool having the same interior curvature as the groove and secured directly to an operating lever 22, pivoted at one end to the base 16 and provided with an operating handle 23 at the other end thereof. 24 represents a tubular cup which is constructed by forming the same in a heated die in a well known manner to those skilled in theart of forming boxes and like articles from paper under pressure in heated dies, said cup having the same exterior diameter as the inner diameter of the tube 4. 25

(see Fi g. 7) represents the neck of the completed bottleas formed in the molds above described, and 26 the mouth ring which isconstructed by heated dies, in the same man-Q ner as was the on 24, and is of such a nature that it may he slipped directly over the end of the neck so asto be secured thereto by a concentric head 27.

Having described the bottle proper and also the apparatus by which saidbottle is constructed, I will now proceed to describe the method of operation of forming the same.

Referring first to Figs. 1 to 4 inclusive, all of the parts of the mold proper, which are seen in Figs. 1 and 4, are first subjected to heat in a furnace to such an extent as will not burn the paper when the mold is being used. The interior mold is then inserted within the tube 4 until the-bottom thereof is flush \viththe lower end of said tube. The

wedge 6 then inserted in the bottom of the' interior mold and the parts as thus interconnected are dropped into the cylindrical opening in the bottom of the base or support 5, so that when the wedge 6 which now rests upon the bench or table is forced forward to its limit, the tube will be firmly secured between the mold and the inner wall of said base. In this position the four arms 7, 7, 7, 7, and curvilinear parts 9, 9, 9, 9 are forced forward by the clamping ring 12, as will be apparent on inspection of Fig. 2, the ring 12 being driven down to its lowest. position as seen in dotted lines Fig. 3. The parts 'are allowed to stand for an instant in this position until the paper sets between the parts 9, 9, 9 and the interior mold.

The operation so far described performs the. first-step of my novel method hereinaftor claimed, in that it molds or forms that partof the tube lying respectively under the curvilinear par-15 9, 9, 9, against the throatand neck parts of the interior forming mold, giving to the major portion" of this end of the paper tube ,the exact conformation or shape of well known types of bottles having cone-shaped throats and cylindrical necks. At. the same time. however, it. will he noted on examination of Fig. 2, there isa surplus of the paper which is squeezed out between i as. t e or t p e e d b h bo y the lateral edges of the curvilinear parts 9, 9, 9-into the corresponding spaces between the pivoted arms 7, 7, 7. This surplus of i'ateri'al is'in the nature of-a plurality of d ldin four Such being shown. The ring 12 *gmwjm ved andthe arms 7, 7,-released that the lateral edges of the curvilinear u'tsf9, Q9, ai e'lrelea'sed from behind the "'(ju-rved' exteirsi'ons-of the paper'seen in Fig. 2. 'lhe edge 6 is now temporarily released ur'sio as to pierinit the bottle as thus-far formed ffa-nd itsflsupporting mold to be rotated a fi-a'c tional part of a revolution so as to bring 'the'eitteriorcurvilinear portions of the folds 13f the surplus material which are to conr-F; stitute the plaitsdirectly opposite-the curtjil lhear parts 9, 9, 9, and the 'parts arc aginjforced'forward through the agency of end fof the neckto "the. lower end of the a Po t of ifihfif-"bottle ,proper. fThe' -f-ring 1-2- and wedges 1'3'..- 'are' 'now- 'removed landthe wedge GfWithdrayvnfi m' the bottom, of the interior m'old'iwhe'ii tl'ieibody'pai't thereof and v inf'co'mpletedFconditionand "ready 'for receivingf the ,'cup -bottom and a mouth ring to a be I applied thereto through: the agency ofthe tool "illustrated 5 40' of "the bottle is and 6,' Whichoperatiomwillnow be de-- scribed; Thej-tool illustrated in thesefigures of, the drawings is first heated to approximately the same temperaturea's-wasthe eni tire mold shown in :Fig. 1 and it isdet-ach ably secured to" a bench or table throu'ghfthe agency of the pins-18, 18,'extending throu h 't-he h'oles -17, 17', 17in the 'base'theieof: T e

- cup 24 is now inserted in the" interior ofithe bottom of'the bottle as thusfar formed withthe' bottom part up, and with theinner side thereof resting against the curvilinear art 19 of the'tool,'with-' the'bottom' propero jthe". bottleresting firmly on'the top s'ur faee of "the hase The operator then-takinghold of -the-=handle' 23 p i head is formed around-the bottom ation of; such edges converge from the: lower.

. I I of the lVGIi'QQ advances the heated male part 2lagainst the bottom thereof which effectually unites the same to the lower part of the body proper. This vpart of the operation constitutes a further step in the completion of the bottle in the sealing or securing of the bottom thereto. The mouth ring 26 is now slippedioverthe neck of the bottlin the manner shown in Fig. 7- and a concentric head 27 is formed therearound in the same manner as the like head was formed around the bottom and with a like tool of smaller dimensions. This operation just described constitutes the final step of the formation or shaping of the bottle and as thus formed it is subjected toa bath of molten paraffin o r'-an equivalent-waterproofing agent, which effectually seals all of the parts together and renders the bodyand throat parts thereofp'ractically transparent;

In the practice of the method hereinbefore described ofmanufacturing. bottles from fibrousmaterial, such as paper, various types of apparatus may be used in effecting such method; orthe samemay beudone by hand by first moistening all of thatpartlof the tube above the-shoulder of the body part 1, and forming the plaits or ribs by'manipulating the same by hand,v after which the folds of the surplus -material=cwhich .is to form said'plaits may be ironeddown with va: heated iron and this entire- -portion ofthebottle as I thus. constructed subjected to a sufficient ,dryinginfluence to cause "it to maintainits shape-onform. .Wh'le I: have -'-described the application of-heat-as one of the steps which constitute the method; bywhich; my I novelbottle 01:

containing vessel is formed,-I'donot-:limit myself to the ;use of heat inforniing the --e m leted bottle, although -such iagent is *pre, erably used; Nordoil' limit tmyselfto thesecuring of the cup Qtawithin the bottom of the body' part, or the m0ut-h-ring.26 to -the neck of the bottle, asvarious means of effecting this result-might be devised, ,the'

essential feature ofnovelty in-my invention lying in the method of operation by which a bottle is formed from a paper or analogous fibrous tube by compression in such manner as to. form strengthening'ribs or plaits between the shoulder ofthe bottle proper and the mouth-thereof, and also in securingto the opposite ends of a tube of ordinary bottle conformation as thus prepared .a bottom and a neck ring,;whieh-rin shall-constitutethe equivalent of the-usila 'eneck rin'g found in glass or other bottles, my invention being generie to a method of operation in the manner described,

Having thus described my invention what I claim and desire to secure by Letters Pat- ,ent of the United 'States-'is- 1. The described method of forming a bottle, consisting in first =constructing a tube of a sheet of paper, then subjectingoneend of such tube to pressure againsttheithroat and neck parts of a bottle-shaped forming mold so as to give to the same a throatand neck conformation of like form, with a plurality of folds of 'surplus'material located radially therearound; then folding the surplus material into plaits e xtendin in the direction'of the length of the mold by the application of further pressure; then securing a cup-shaped bottom to the-lower or open end of the body part by indenting a concentric bead between the two. parts through the agency of pressure,'and finally securing a strengthening ring to the outer end of the neck in the same manner,

2. The described method of forming a bottle from paper or like pliable material, consisting in (1) constructing a tube from a sheet thereof; (2) subjecting one end of such tube to compression about one end of a forming mold havlng a throat and neck until the paper pa-rtakes of the shape of the V mold and the surplus material is formed into folds .ra'dially disposed therearound; (3)

forming or shaping, said folds into boie -plaits by )ressure which plaits overlap the throat an neck as first formedand lie in the direction of the len th thereof; (4) securing a bottom of cup Form or shape to the bottom of .the tube byindenting a concentric bead between the two a enc of re'ssure' an 5 securin a b i 7 C:
