fffo il aC/ione, 'it may concern s B it known that ALBERT ALFRED- a, a citizen of the United States, and lent of the city of Baltimore, in the 1 ci' iilaryland, have invented a certain and useful Means for Bottling G'aseous ouids; and I do hereby declare that the following specification, taken in connection -with, the dravifings furnished and forming a part of the saine, is a clear, true, and comilcte description of the several features of my invention.

@ne object my present invention is to o control the venting of gas from the bot- ',le in relation to the supplying of the 'irafious liquid that the pressure will rise i he filling chamber and bottle just bethe bottleiis closed, so that the bottle be capped With a gaseous pressure the ein eipial to that at the supply font.

notlier ohject of my invention is to provide such means for venting air and gas from the bottle or other receptacle as will secure a rapid ill.

Another object is to provide means for venting :from points at diiferent heights in the bottle to get diiterent filling levels.

My present invention relates to the type of bottling machine disclosed in Letters Patent of the United States #1,012,984, granted to me December 2G, 1911, and like in said prior invention the present one, as to sonic of its features, may be carried into effect hy a machine which embodies only the elements which form a single bottling mechanism, the invention, however', being capable of embodiment in a machine of multiple form in which a plurality of sets oi such elements or bottling mechanisms are included.

I rihe frame of the machines embodying the invention may be of any suitable construction. In the particular machine selected to disclose the invention, the frame includes a main plate A; end plates, one of which is shown at A; a foot plate A2; two vertical posts, one being shown at A3, and a head l plate A4.

` A machine embodying the invention in its best form will have its Working parts lomver driven, and While the means for transmitting power to the -Working elements may be varied Within Wide limits, in the particular machine illustrated Vthe transmis-l sion is by a main shaft B carryingjcams ior imparting some or the movements, and

an upper counte?1 shaft B2 connected' with the main shaft by a sprocket chain B', the said shaft B2 ing other movements as will hereinafter appear. Y j j i Each set of bottling mechanism, Whether the invention he embodied in a machine 'of single or multiplev form, will include a bot-i tle presenting de yice, and While this device carrying means for impart?v indicated generall yat C, 'together with` its operating mechanism, may be varied widely it herein of substantially .the same form as that illus- -trated' in my prior patent above referred in construction, I have shown to, the said bottle presenting device being slidahle vertically insuitable -bearings `with which it has a splined connection to prevent turning, and being actuated from the main shalftby a 4Cain Cu. and a yoke lever, the llatv ter bearing on a llock nut()2 which is adjustable on the lower screw-threaded stem of the bottle presenting device. By. 4this mechanism the bottle presenting vdevice is given a reciprocating movement vertically'` to present the bottles tothe filling mechanism andto the cappingmea'ns hereinafter 'referred to.- 'lhe immediate support for the bottleforming a part''ofthe lbottle pre'- vsenting device may be offvarious forms, but

in the particular ,machin'c 'asliovvnV ll employn a=yielding header top@3 upon which the bottle rests.

Machines embodying .the invention will include suitable means for sup liquid to the bottles to be filled, lw'hicg means may be of Widely dierent construction. In the form of the invention `herein disclosed the liquid supplying devices-delivers the liquid to be bottled through a filling chamber G, the bottle, prior to the '.delivery of the liquidfhaving beenlpresented to thelilling chamber by the bottle v'presenting device.

In bottling machines itis frequently de sirable t0 bottle-combinations of different ln'nds oi liquid,v Ivsuch, iiorinsftance, as

charged and still liquids, thelatter being? a iavoring extractv known as syrup When, as in the machine shown, carbonated- Water having a'` iiavoring 'extract added `.thereto is to be? bottled, orv When, for any ableount. orfcarbonatingv machine.. The

other? source illustrated is the ysyrup -pump F which is representative of any suitable lform of device for supplying the syrup. The discharge of liquid, as carbonated Wavter, through the .duct F2 may be controlled by a variety 'of means. ln the particular construction shown' this consists' of a valve E pressed upwardlyupon its seat by a suitable spring, said valve having an upwardly extending stem projecting above its housing. When syrup is to be used in bottling, the discharge thereof intothe conduit .F2 may take' place from the pump F iny any suitable manner, as, for instance/by Way of' passages and check valves suchfas shown in the Patent #1012984, above mentioned.

'In bottling liquids under pressure, the r lling chamber should be tightly 'closed when the bottle has been placed in com munication with. the interiois` o .the ysaid chamber. The means for doing t is may 'be ried by a ring varied in orm.- ln the construction. illus# trated this means includes a gasket Gr car- G2 movable` vertically and suspendel from the filling head by a pintle shown in Figs; l0 and 1l. While the operating means for this gasket and ring may be varied Within Wide limits, in the construction illustrated, a yoke lever H. is employed `pivotally' mounted on thel housing of the filling head, the, arms of said lever operating against the under side of lugs projectingv from the ring G2, all as set forth in the above mentioned patent. The yoke lever H isv operated by a rod H2 from cams H on the shaft B, as shown in Figs. l andS. When the yoke lever s swung upwardly, the ring G2 with the gasket G is also moved upwardly, causing the gasket to be contracted for making tight packing contact with the bottle. When the gasket ring is.

dropped, the normal annular evening in the gasket is somewhat larger than the diameter 'of a capped bottle, to allovvthe bottle which has been filled and capped to be lowered and removed. l v

As in thevpa'te'nt above referred to, I pre fer to control the supplying of the liquid or liquids to the filling chamber by the presence of the bottle in propor position for filling.v `Various means may be used for this purpose. One embodiment of a bottlecontrolled -liquid supply mechanism may consist,' as in the particular construction illustrated, of a lever D pivotally mounted -on the bottle .presenting device C?, and

spring pressed, as shown in` Fig. 3a, said lever, near -its iulcrum, having gear teeth meshingfvvith elongatedteeth on a vertically v "reciprocating actuator rod D', which is op-f erated from a cam D2 on the main shaft B,

`for instance, as in 'the patent 'above vmentioned. The actuator rod D. in the partiv cular construction illustrated is fprovided With a tappet E for depressing and opening the Water valve, and also atappet arm l?" arranged at a different angle from the tappet Ef and above the same. The actuator rod, While in constant reciprocation, may be said to be normally inoperativein that so long as no bottle is present on the bottle. presenting device C3 rfor jlling, the tappets on the actuator will ,not strike the Water valve stem or engage'the piston of the syrup pump, but. when a bottle is placed on the bottle presenting device /the' lever D Will'bepressed back,'the actuator rod Will be rotated, and the -tappets thereon brought into proper position to engage the stem. of the Water valve E and the piston of the syrup pump F, so that on the downward movement of .the rodY liquid Afrom these ,two sources-Will-be delivered to the duct F2 to flovrinto the lling chamber, by the downwardly inclined port of Figli?.

in machines including; the best embodi.

. of which, acting on'the iiange of the cap.

ments of my invention, means will be provided for applying closures to the filled bottles and these, preferably, will be adapted to apply metal sealing caps such, for instance, as caps of the well known crown cork type. ll/hile the closure applying means may be of a variety of formsand will, of course, vary according to the character of the closure employed, in the particular machine illustrated the closure applying mechanism includes a cap applying tool I located at the top of the filling chamber. This tool is tapered upwardly on its interior, and in the best construction it has associated therewith a capping plunger I backed by a spring I2, which bears on the flange I3, holding the same normally in gastight contact with the tp of the filling chamber. The functionr of this capping plunger, when such is used, is to apply pressure to the top of the cap, thereby forcing the cork disk or other packing usually contained in the cap firmly against the bottle lip before or near the beginning of the cap applying operation, which consists in bending the flange of the cap inward so as to lock it torthe bottle, this bending and locking resulting from forcing the bottle head with the cap thereon upwardly into the tapered throat'of the tool I, the tapered walls bend it downwardly and inwardly, as is well known. The4 closures may be supplied to the bottles to be capped in various ways, but preferably they will be fed automatically into the filling chamber and positioned on the bottle heads. The cap supplying means. when such are employed, may vary widely in construction. In the particular construction illustrated, the caps will be held in a mass within a. hopper L supported from the upper shaft B2 and having a chute extending down therefrom, as in the patent above referred to. The hopper is provided with any suitable agitator for keeping the caps in free condition for feeding down the chute, The hopper, with the chute, can have oscillating movement about the shaft 152'," and as a forni of connection, representative of any which might be used. for moving the chute to and from the filling' chamber, I show links L2 and L3, the former being connected with the gasket controlling'lever H to be operated simultaneously therewith. lVhile the placing of the caps into the filling head may be accomplished in various ways, in the best construction the discharge of the caps into the filling head takes place through a cap port K in the side of the head. the lower end of the chute, for this purpose. being advanced, as shown in dottedrlines in Fig. 10, to register Awith the cap-port. lVhere. as in the v)articular machine illustrated, the bot.

tlcs are to be iilled with liquid under gaseous pressure and then capped by introducing the caps through a. cap port, means are pro- ,..vided for sealing the filling chamber gas tight at the cap port, and while such scaling means may assume vvariousfornis, in the particular machine illustrated a pad block K is employed to seal the cap port I( after the cap has been introduced, to be engaged with the bottles. The means for operating this pad block may vary within wide limits. In the particular construction shown it is mounted on Vthe gasket controlling lever LII so that as this is raised to cause the contrae` tion of the gasket to make a gas-tight contact with the bottle, the pad block will be forced to its seat around the cap port to seal the saine gas tight. As the pad block is 'moved to seal the cap port, the cap chute is retracted to the position shown in Figs. l0 and 11. As, however, in the particular machine shown, the construction and operation of these parts is the same as in the patent above referred to, it is not necessary to describe them more at length herein. While the cap may be assembled with the bottle in various ways, in the particular construction shown I employ a cap finger K2 for' this purpose. The cap, when introduced into the cap port. is supported to one side of the axis of the filling chamber, as indicated in Fig'. l0, its position being determined by abutments marked h2 in the patent above referred to, against which the edge of'the cap bears. The cap linger K2 is spring pressed, as in the said patent, and when the pad block is in position to seal the cap port the said finger bears upon the edge of the cap, as shown in Fig. l0. filled it is thrust upwardly within the filling chamber from the position of Fig. 10 to that of Fig. ll. In'lits upward course its lip strikes the cap and tilts it up .sufficiently to free it from the retaining abutments, whereupon it will be thrust into position ovei the head of the bottle by the spring-pressed cap finger, and it will then be car'ried up against i the capping tool I.

lVith a gravity cap feed, when such is used, as in the particular form of machine illustrated, means are provided for holding the caps in the chute when it is retracted 'l'rcni the cap port. lVhilc a variety of forms of devices for this purpose may be provided. in the particular machine shown a spring pin L is'employed. said pin being carried by an extension of the lever or link Lg. ll'hen the chute is advanced into registration with the cap port, this pinis lifted to allow the lowermost cap, under thc weight of the column of caps in the chute, to enter the cap port and assume the position shown in Fig. l0. against the abutments, and to one side of the center line of the filling cliainber.- Then the cap chute is retracted,

plunger I and to the capping the spring pin L engages the cap, which is After the bottle iscated that in machines which are toinclude any or all of the groups of mechanism, the" construction thereof may assumeaJwidevmf rietyof forms, those chosen to illustrate' these parts of my invention being represen- A tative ofany suitable'forms ywhich may vbe used. fIwill nowV refer to means `of venting', .the gas and air from the bottle.

u In bottling charged or carbonated'liquids,

the i11ing-chamber,as above described, vis

, provided with means for .effecting a gastight closure thereof, leaving the interior of the bottle, however, iny free communication with the said filling chamber. When. this isY done, it is usual ito provide a venting'eonduit ,or passage to allow the escapieJ of the air which is driven outof the; bottle by thel entrance of the liquid thereinto. Machines Vso embodying the invention in its best form' will be provided with sucliventing conduit,

and in the best constructions embodying the invention this venting conduit will be open during the time the liquid is entering the receptacle and will be closedbefore the valve which controls the inflow c oufluit is closed. A construction in which the venting conduit remains open as above stated and is-closed before theinlet valve for the inflow con? duit is closed possesses a marked advantage. The air in the receptacle to be filled is al lowed to escape freely and rapidly during the flow of the liquid into the receptacle, so that thereis noY back pressure on the enter'- ing current' of liquid. When, however, the desired amountofliquid has ventered the receptaclevthe shutting off. or closing of the venting conduit establishes .a gas pressure in vthe filling chamber and receptacle which-l checks the inflow of the liquid, and the pressure in the receptacle` will `become equalized with the pressure in the carbonator or source from which the liquid is obtained, so

that at the' time the inlet valve is closed and prior to the closure applying operation, a v

pressure of ga's .will have been established in the receptacle vwhich is equal to the gas pressure in the carbonator. In bottling carbonated liquids it is desirable to'utilizethe yf'ull pressure of the carbonator and also to obtain the desired pressure of gas in the receptacle. I n constructions in which the inlet valve is. closed before'the venting or snif-ting as' itis sometimes called is completed, there is almostv invariably a loss of gas in the receptacle.A 'In order,- therefore, to obtain 'thedesired pressure in the receptacle', it-is necessary, in such machines, to employ a vhigher pressure in the carbonator than it is `desired ultimately to obtain in the receptacle, the AeXtra amount of gas in the carbonator` beinglwasted.

meats@ .closingfof the-venting conduit fpriorf-I lto the' closing-of the inliqw conduit may be. f varied-within vvideflimits.` the particular `Lconstruction illustrated, there is' employed a Vventing tube M, Figs. 2,015,7,8 and 9, having ports M5 and having at itslower end a small escape port leading in to the interior of they ltube.. In a machine employing av capping plunger I preferably locate the vent tube` within said plunger with its stemvM projecting above the shank I4 of the same. Be-

low 'the union of the stem and tube, vin the particular construction chosen to'illustrate 'this part of my invention, a collar M2 is fixed on the tube against which a spring'l 3.* bears, the upper end of the spring abutting against a head screwed into theA shank I4 of the capping plunger. This spring is under light tension and merely causes the .tube to slide downwardly after it has been lifted, and enables. the ytube to yield shouldv its lower end strike an obstruction. The eX- treme'low position of the tube in relation to termined in various ways. As one means for. this purpose the collar M2 may be employed which rests/upon a seat in the capping plunger, as shown in Fig. 2, adjacent which a lateral port is Vprovided in the capping plunger for the passage of air incidentvto the vertical movements of the collar 4within the cylindrical space of the capping plunger. Means may be provided, variable within wide limits as to construction, for'var'iably limiting the downward movement of the tube so that` its lower end .may occupy variousheights in relation' to the bottle to -de-A termine the line of fill. In'the particular [construction shown, and as representative of any means which may be usedpforthe purpose, 'I show a collar Mi on the stein of 'the ftube above the tubular shank of-the capping plunger, a thumb screw in the collar enabling it to be locked to the tube Stemat i differentpoints thereon, recesses being indicated in the tube stem at various points in Fig. 6. vBy'this construction, or any othery suitable constructionl devised for thejfpurpose, provision is made l,for locating the lower end of'fthe vent tube. at different 115" heights in relationy to the .bottle trated in Figs Q,''TLand-S. The vent tube itself may as jillusbefvariously con#` structed, but in the particular`construction;v shown I employ a tube screw threaded interf2() `nished"to`secure variations in theventing 12.5

water is delivered, and so holds it back inits duct; the water valve being still open, the vent tube is promptly lifted, and made inoperative, the bottle head and neel; is at the' same time forced into the chamber until .the bottle releases the cap at the cap port and Acarries it up into compressing contact with the capplunger, thus initially, by the packing in the cap, tightly closing the bottle ju'st before, or about at, the time the water valve closes and absolutely cuts oil' the liquid. The bottle is thus initially closed at a time when its contents. are under a gaseous pressure equal to or greater than that at which the charged water is delivered to 'the chamber. The continued upward movement of the bottle causes the capping tool to lock the cap to'the bottle, as shown in Fig. l1, and the lifting of the cap plunger by the bottle enables the gas to .cscapefrom the chamber into the waste pipe which, at all times, receives the air, gas an'd any 'little'liquid vented through the tube. The retirement of the vent tube is closely followed by the entering bottle head and necl, which, in bulk, occupies much more space in the chamber`than the tube didthus' tending to increase the pressure'in the chain'- ber and bottle up to the moment the cap plunger is lifted after first `having tightly closed the bottle by compressing the cap packing. s

lt will be observed that my invention permits initial venting, z'. e., while the bottleis in course of filling, up through the capping tool and capping plunger, and axially in relation to the filling chamber and bottle, and furthermore, it will be observed that the vent tube, in one aspect, forms a -valve located above the capping .tool and withinthe housing, said valve being'seated in the capping plungeryand controlling an outlet passage or passages leading therefrom into the housing and thence to the out,- side. This provides a compact and Asimple construction in which the functions of the well known parts, such as the capping tool,
