APPARATUS roa FORMING .mp rinsEm'me RECEPTACLE-CLOSURES.

Be it .:lmown"that I, CHARLES FnANois diiimmsya citizen ofthe United States, re-

' J into cylindrical paper cmilk -orlother liquid or solid goods. illustration, the apparatus chosen is such as siding at Washingtom-in the District of Columbia, haveinvented [certain new and useful i Improvements I in Apparatus for Forming and Inserting Receptacle-Qlosures, ofwhich' the followingis a specification, reference being had therein to the accompanying drawing. 7

This invention relates to apparatus for insertingthem in reforming cup like closing disks and inserting them in flexible receptacles for conta ning or is adapted for cutting. disks from" paper stock-shaping or drawmgthem-to the form of shallow cups and forcing them directly bottles (by the action of a plunger which first co-acts with an annular die in drawing them into proper shape) without releasing them or giving and instantly releasin 40 than inusing metal.

them an opportunity to spring out of exact form given them .by the forming devices. it is essential that the the instant when insertion begins. Usually bottle bodies are presented automatically in rapid succession, each resting for aninStant to receive its closure and then moving on togive place to the next. Itapidity of opera- 'tion is practically indispensible in this particular art, and difliculty has been found in adjusting the bottle body to exact form and exact position during its momentary rest,

it before it is moved onward. It is also to e noted that the difliculties where paper is used are much greater Whatever the material, the difficulties are overcome in placing the bottle so near'the closure forming devices that the closure is-partly inserted before it is completely formed, and in pro-' viding simple bottle adjusting devices which are compelled to act synchronously with the inserting lunger, so that the bottle is necessarily 'he d prec sely'in form and position during the proper interval, and no longer, whatever the speed of operation.-

is-a side elevation, partly in section, of so much of the machine as is needed to illus-,

trate the construction and action of the novel devices. Fig. 2 is a section on the line 2-2, Fig. '1. Fig. 3 is a section on the line In these views, A, A represent uprights provided with vertical ways for a reciproeating cross-head B, C a support for an an--' nular cutting die plate D and a smaller concentric forming die E. The crosshead carries a plate F provided with a hollow cutting, plunger G adapted to cut plane disks Patented Apr. 5,1910,

H from paper stock I, placed u on the die D in an suitable manner. ithin the longer 4 reciprocates a difi'erently timed ornnng and inserting plunger J The bot- ,tle K to,-be closed is brought to rest below theplungers and is supported with its open end just below the die by any suitable device, for example, by a plate L of an intermittently moving feed chain, not otherwise shown. Centrally pivoted at M in the support C, upon opposite sides respectively,

of the bottle are adjustin jaws N, eachhaving its inner end adapte to fit one side or half of a cylindrical bottle of the size used. These jaws assume the position shown in dotted lines when the cutting plunger is in raised position, leaving the bottle free. to move bodily between them. Through the outwardly projecting end portion N of each jaw is passed a rod 0, and the end portions of each rod lie, respectively, in slots in the lower portions of bars 0', the upper ends of which are pivoted to the plate carried by the crosshead, as shownin slots Q. "The parts are so proportioned that when the cutting plunger nears thelower limit of its movement, the rods 0, lying then in the upper ends of the slots, are suddenly forced downward swingin the jaws to the positions shown in full lines. The bottle end is thus suddenly grasped, pressed into true cylindrical form and accurately held in registry with the plunger J, which instantly descends forming the disk into a cup and insertin' it in the bottle, the lower part. of the flange closure or cu bein inserted before the upper portion 0 the ange leaves the forming die. ,The lungers then rise, releasing the jaws which fall to initial position, the falling being accelerated if desired bysprings P.

, Obviously the action of the jaws or adjusters would be the same whether or not the inserted closures be cup-like, and it is also evident that they may be actuated difierently without departing from this part of my invention, so long as they are compelled to act synchronously with the insertin device. It is also plain that it is optional whether the bottles be circular in cross section if the jaws or adjusters correspond in form with the selected cross section; and indeed the jaws permit the use of certain noncylindrical forms not otherwise practically available. I

What I claim is: w

1. The combination with a reciprocating forming and inserting plunger, of an annular die adapted to co-act therewith in forming a closure, an alining support for a pliable receptacle, normally disengaged receptacle forming jaws arranged to grasp the end'of such receptacle and press it into shape and position near said ;'die, and automatic meansfor actuating said jaws as the plunger makes its inserting advance.

2. The combination with a reciprocating closure inserting plunger, of an annular coacting formin die fixed in the path of the plunger, an a ining support for a flexible bottle, jaws arranged to be moved into and out of position for pressing the open end of such bottle into exact conformity :with the shape of the closure to be inserted therein by the plunger, and means whereby the insertin advance of the plunger. moves said jaws into bottle-shaping position alongside said die, substantially asset forth.- 7

3. Inapparatus of the class described, the

combination withan annular forming die,

of a larger concentric cutting die above the same, a reciprocating formin and inserting lunger arranged to co-act wlth the forming 1e, a reciprocating sleeve-like cutting opposite sides thereof, and automatic means for compelling said jaws to seize and adjust theopen end of a receptacle upon said support an instant before insertion of the closure by the forming and inserting plunger. In testimony whereof I aflix my signature in presence of two witnesses.
