BOTTLEFILLINGy MACHINE.

Specification of Letters Patent.

Application filed June 13, 1907. Serial No. 378,866.

Patented Apr. 11, 1911.

To all whom, it may concern:

Be it known that I, MATHIAS JENSEN, a subject of the King of Denmark, residing in Copenhagen, Denmark, have invented a new and Improved Bottle-Filling Machine, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in machines for lling bottles, cans, or other containers with liquid or semi-liquid` substances, and more particularly to that type of machine in which a series of empty containers are continuously delivered to the machine, automatically filled in succession, and continuously delivered theref IOm. In a filling machine embodying all of the variousv features of my invention, the containers are conveyed along an endless belt to the machine and the latter operates to remove them from the belt, fill them in succession, and return them to the belt. The machine is so constructed that after filling each bottle, the liquid is removed from the bottle to a predetermined level below the mouth thereof, irrespective of slight variations in the height of successive bottles.

The invention consists in certain features of construction and combinations of parts 'hereinafter described and more `particularly pointed out in theclaims.

Reference is to be had to the accompanying drawings, formin a part of this specification, in which simllar characters of reference indicate corresponding parts in all the figures, and in which- Figure 1 is a front elevation of a machine constructed in accordance with my 4invention; Fig. 2 is a transverse section, portions thereof along the radial lines 0 to 5, inclusive, being taken in. planes indicated by the corresponding lines. in Fig. 4; Fig. 3 is adevelo ed elevation showing the entire circum -erence of the central rotatable portion; Fig. 4 isa vertical section through one of the filling devices; Fig. 5 is a transverse section through, the valve of one lillingdevice; Fig. 6 is a transverse section on the line ST6 of Fig. 4; Fig. 7 is a vertical section through a portion of the lling device 'and the float controller therefor; Fig. 8 is a transverse section on the line 8 8 of Fig. 7, and Fig. 9 is a View similar to Fig. 6, but showing the parts rendered inoperative by the absence of a bottle.4 4

chine illustrated in the accompanying drawings are supported in a main frame A, wlnch latter is in the form of a verticallydisposed cylinder having openings'in the I a base frame A1 and is secured thereto in A any suitable manner, as, for instance, by bolts or screws A2. The base frame is supported by suitable legs A3, and itserves to support a main drive shaft B, having on one end thereof a pulley B1 and on the opposite end thereof, a bevel latter meshes with a bevel gear Bcarried by a vertically-disposed shaft Bt.` Parallel to this shaft. VB4 is t-he main upright revolving shaft C, which carries the filling mechanism. The shaft is driven from the shaft B4L by suitable gearing, including a gear wheely Cl secured to the shaft C, adjacent its lower end and meshing with a pinionB5 carried by the shaft B4. The main upright shaft C is provided with a sleeve keyed thereto, which sleeve at its lower end is provided with outwardly-extending fingers or projections C2, constituting a spider for moving the bottles and above this spider are outwardly-extending flanges C3, C4 and C5, which may all be formed integral or may be formed of separate members rigidly secured together, and all rotatable with the shaft C. The sleeve, fian'ges and spider are preferably held from rotation by means of a key C, and there are held against vertical movement by means of a shoulder C7 adjacent the upper end of the shaft. These parts are supported at their lower ends by a nut C8, threaded on the shaft C below the top of the base frame A1, and the shaft itself and the parts carried thereby may be supported-vertically by any form of thrust bearing, as, for instance, a plate C".

My'invention is adaptable for use in filling any kind of container, butj the specific form illustrated is especially designed for filling bottles. The empty bottles are delivered to the machine by an endless belt W, having a portion thereof extending substantially tangentially of the machine and this same belt serves to convey the filled bottles from the machine. The belt is disposed upon approximately the samfe horizontal level as the upper surface of the base frame 4A1 and the spiders on both moving arms are gear B2, which disposed at such an elevation above the base frame'that the/bottles may be enga-ged by g said shaft. As the gear wheels C1 and D2v intermesh, the peripheral speeds of the spiders C2 and D will be substantially the same, and the arms are so disposed that the spider D will operate to engage with successive bottles on the belt and deliver them to the spaces intermediate the successive arms of the spider C2. For retransferring the bottles from the spider C2 to the belt at the delivery sideof the machine, I substantially duplicate the spider D2. This second transferring means includes a spider E, mounted on a shaft E1, which latter is driven by the engagement of thegear wheel C1 with a gear E2 adjacent the lower end of said shaft. In connection with the three spiders and the belt, I preferably employ suitable guides fpr maintaining the bottles in their proper positions. These include curved plates, bars, or strips, E3 for engaging with the outer sidesof the bottles and holding them in engagement with the spiders D and E while the bottles are being transferred, and a curved bar E4 for retaining the bottles bev tween the arms of the spider C2. The guides Es may extend along the outer edge of the belt and yadditional guides E may be disposed adjacent the inner edges of the belt to -form channels of which. the belt constitutes the bottoms. As both the spiders D and E are driven from the gear wheel C1 and the power is delivered directly to the latter, it will be evident that the parts passage F3 in alinement with the shaft C's always maintain a constant relative speed.

lThe bottles when delivered along the belt W may be carelessly placed thereon at varying distances apart, and ,it isy desirable that theirpositions be controlled and regulated as they approach the spider D, so that they will enter the proper recesses between the arms of said spider. this, Ifprovide bottle-spacing and controlling mechanism, including-a series of lingers or prongs L. Each of these lingers has its free end extending out over the belt W and into the path ofthe-bottles delivered along.

said belt. `The fingers are mounted on suit'- able pivot pins supported in a frame L1,

"and the fingers are normally held resiliently in the path of the bottles lby suitable springs L2 encircling said pivot pins. All of the fingers are connected together by a link L7, so that a movement of one nger insures a For accomplishing j movement of each and all of the fingers. The first fingerof the series is controlled by an arm L4, pivoted on-apin L5v in the frame L1 and rigid with an arm L extending into .the path of a series of pins L3 carried by. the gear wheel D2. The pins L are dis osed in such relationship to the arms o the lspider D, i, that each time an arm of the spider comes to the proper position, the tingers L are wlthdrawn and each bottle on the belt is permitted to advance one step and the lirst bo-ttle of the series will enterthe proper position in the spider and be delivered to the filling machine.

After the bottles leave the spider DV and are moved about the circular path by the spider C2, the filling mechanism comes into operation and delivers to each'bottle a measured quantity of liquid. The filling mechanism, as previously stated, is rotated with the main shaft C, andl there are as vmany separate filling mechanisms as there are spaces in the spider C2 to receive bottles. In the present instance, I employ eight separate filling mechanisms, and, therefore, all of the parts rotatable with the shaft C are provided eight times. A detail description of one of these filling mechanisms is thought to be suiicient, reference .being had particularly to Fig. 4. Above the shaft C and in vertical alinement with each of the several bottles carried bythe spider C2, I provide a. plurality of measuring chambers F, each preferably in the form ofl a cylinder and having valve-controlled communication with a' main supply pipe and with a delivery pipe to the bottle. These measuring chambers are preferably formed' in a separate member secured 'to the flange C5 by bolts F2, which flange forms a flooring or bottom for each ofthe measuring chambers and also for an annular chamber F1,disposed within the annular row of measuring chambers F. The annular chamber F1 is in open communication with a centrally-disposed' conduit or and rotatable therewith. At the upper end, the conduit F3 is connected to a general` supply pipe Fl, by means of an elbow F8, and t-he joint between the elbow and the conduit- Fs is rendered substantially liquid-tight by a packing F7. The pipe F4 contains a controlling valve FE and the elbow carries an air escape pipe F, through which'the air withinfthe annular chamber F1 and the connecting parts may escape while the machine is being vfilled for the first time.

Within each measuri'n'er chamber or cylinder F, there is 'mounte a vertically-movable piston G. Extending upwardly from. the piston is a piston rod G1 connected to a guide rod G2 Vextending substantially parallel toy the piston rod and adjacent the outer surfaceA of the cylinder. Intermediate its ends, the guide rod carries a roller G3 esame "andv the amount of liquid delivered to the measuring chamber and forced from Ithere to the bottle, is determined. The ,guide rod G2 has a horizontally-disposed portion extending from the piston-rod G1 to the main portion of the guide, and this-horizontallydisposed portion is slidable upon a rod G5,

which 'serves to prevent the guide rod from moving in 'other than a vertical direction. The rod G5 is supported at its upper end by an outwardly-extending bracket rG", carried by an annular iange G", secured to the member forming the several measuring chambers. This iian'ge may be held by bolts Gr8 and its central portion may constitute a gland or packing'about the central conduit F3. The ange G7, also preferably carries a small adjustable slide G9, adjacent the upperendof the cylinder -and adapted to engage withthe piston and serve as astop to limit the upward movement of the latter and prevent its displacement from the cylinder, as well as control the maximum quantity of liquid which can be forcedinto the measuring chamber.

-For controlling the inhausting and exhausting of the liquid, I provide a valve H, directly below each measuring chamber. The valve is holldw and provided with ports b, b, which may register with corresponding ports in the'bottom of the supply chamber F1 and .the measuring chamber F, when the valve is in one position, and Ahaving 'ports a, a, which may register with the -I'ggrt in the bottom ofthe measuring chamr and with the inlet end of the supply pipe .to the bottle, when the valve is in a. second position. The valve 4is radially disposed in respect to the main shaft C, and 'at the outer end of the valve'stem, I provide a collar 'terminating in two oppositelydisposed studs lor projections H1 and H2, by 'means of' which the collar andthe valve are 'rotated at the proper time: The main frame ofthe' machine carries two stationary studs or projections H3 and'H, so disposed that 'as the shaft C and the parts carried thereby rotate, the projections H1 will engage with the single projection I-I3 at one part 'of the circuit and rotate the valve in" one direction, and each projection H2 will l engage with the projection I-I4 at a different portion of thecircuit, to rotate the valve in the opposite direction. The two projectionsl H3 and I-I4 are at approximately diametric'al'ly opposite points on the machine, so 'that the valve will be moved twice, once in each direction during a vcomplete rotation of the shaft C. The projections H4 serve to turnt-he valve, to bring the ports 7), into operation and permit the measuring chamber to be filled, while the projection H3 serves to bring the ports a, a `into operation and permit the bottle to be lilled from the measuring chamber. When the ports b, b are in operation, the liquid delivered under pressure will enter the measuring chamber and raise the piston G into engagement with the stop G", where it will remain until the valve is again rotated.

v The liquid is conveyed'from the valve H to the bottle through a pipe formed of two telescoping sections, the lower section I being vertically movable, and the upper section I1 being rigid with the flanges CA1 4and C5. The lower or movable pipe section I carries a bracket I2, vertically adjustable in respect thereto and normally rigid therewith, and upon an outwardly-extending stud or pivot integral with the bracket is a roller I3. This roller engages with a fixed camway I4, which by` its engagement with the roller I3 controls the reciprocating move ment of the pipe I. To prevent rotation of the pipe I, I provide a stationary rod I5, along which the bracket VI2 may slide, but which serves to prevent rotation of the bracket about the pipe. At the lower end `of the stationary pipe section I1, a suitable packing I is employed, to prevent leakage between the two pipes, and at the lower end of the lower pipe section IT is .a valve I2, serving to close openings I in the sides of the pipe, and normally held over said openings by asuitable coil spring Is. The tension of the spring is such that, together with atmospheric pressure, it will close the lower end of the 'pipe as soon as the valve H is closed, and thus the liquid remaining in the pipe will be prevented from escaping after the bottle is removed.

Toinsure the proper positioning of the bottle mouth in regard to the pipe I, the flange C2 preferably carries a curved collar K, shown in section in Fig. 2. The main frame carries a guide K1 above the spider I) and so disposed as to force the bottle neck into the curved collar and retain it downwardly into the mouth of thebottle.

A In order to prevent the opening of the valve and the delivery of liquid in c'ase `no bottle should arrive along the belt in time to be received in the proper position in the spider C2, I provide mechanism controlled bv the presence of a bottle for throwing cer.- tain elements ofthe mechanism in operation only in case a bottle is in the proper position.

'This mechanism includes a depending plate or `bar M. hinged at its upper end to a bracket M1, rigidly secured to the main frame A at the entrance side thereof and at approximately the level of the flange C3, as indicated particularly in Fig.v 4. A vertically-disposed rod M2 is mounted intermediate the plate M and the frame and extends vmechanism will operate in its through' the bracket M1. This rod carries an arm M3, engaging .with the rear side of the plate M, and also carries a second varm M4 at its u per end. vThe arm M4 is connected by a linl; Mi to 'a plate M, which carries a portion of the camways G* and It, and the projection H3. The late is supported by two bell crank levers 47, each of which is fulcrumed on the main frame and has its opposite ends projecting through the frame and connected together by a link M8. A spiral spring M9 on the rod M2, servesto hold the plate M in the path of the bottles as they are moved along by the spider C2, and it also servesto hold the plate M closely adjacent the inner surface of the main frame A, as indicated in Fig. 9. This brings portions of the camways G4 and I* and the projection II3 out of thepath of the rollers '"Gr3 and I3 'and the valves, so that in case no bottle is in position inthe spider, the operating parts of the lling mechanism remain stationary during the rotation of the shaft C. When a bottle is in position, the plate M is moved outwardly and the parts are broughtl to the position indicated particularly in Figs. 4 and 6. Now, when 'the shaft C is rotated, the

proper sequence and the pipe I will be projected into the bott-le, the valve H will be rotated and the piston G will be forced downwardly to deliver the liquid.

The mechanism above described. serves to fill each and all ofthe bottles with the same quantity of liquid, said quantity being determined by the positions of the several stops G9. In lilling bottles withcertain kinds of liquid, it is desirable that the neck of the bottle should remain empty for a definite distance down from the mout-h, lrrespective of the height of the particular bottle.

As is well known, bottles 'of the same kind vary slightly in height, and in order to provide for this variation in height, and at the same ltimeleave an empty space of definite height in the neck of the bottle, I so construct the mechanism, as to deliver to each bottle a predetermined quantity of liquid which will be more than suiiicient to fill the bottle, and then to withdraw from the mouth of the bott-le a suiicient quantity of liquid to lower the level to a definite distance below the mouth of the bottle. For accomplishing this purpose, I provide the mechanism, a portion of which is illustrated particularly in Figs.l 7 and 8. The liange C3, adjacent each pipe I, carries afloat N, open at its lower end and -supported within a casing N1. The iloatis slightly smaller than the casing and is held concentric therewith by longi# tudinally-disposed ridges4 or anges N2, as

illustrated in Fig. 8. The upper end of the ioat carries a rod N3, extending through an opening in the upper end of the casing N1,

and a packing ring N* is provided which will engage with a Bange on the inner' surface of the top of the casing, to seal the latter substantially air-tight when the float is raised toits limiting` position.. The'bottle as it is filled is automatically raised into engagement with a packing ring N5, encircling the pipe I but spaced therefrom, and the interiors of the casing and ioat are both in open communication with the interior of the bottle througha. passage N6 and the annular passage between the pipe I and the packing ring N 5. The stem N3 of the floatl is provided with a spring N7, the j with the packing rings Nl5 during the time t-he last portion of the liquid is delivered to the bottle and a portion thereof withdrawn, I provide a lifter O, shown particularly in Fig. 3. This lifter is pivoted to two arms O1, 4O2, hinged to brackets O3, O",-carried by the frame A, and in connection with one of these is a spiral sprin O5, for raising the lifter and the bottle. ne end of the spring is connected to a rod O, provided with a nut O7, whereby the tension of the spring may be readily adjustable. The gear wheel C1 of the shaft carries a series of cams O9 on its under side and adjacent its eriphery and the lifter O carries a'roller (l lying in the path of thesecams. The spring O5 normally holds the lifter in raised position, but as each bottle approaches the lifter, the latter-is depressed by the engagemen of a cam O9 with the roller O8, so that the bottle may readily pass on to the lifter, whereupon the-lifter is immediately released, and the bottle raised upwardly into engagement with the packing ring N5. In order to retain the bottle in its ',raised position for a short time after it leaves the lifter and to accurately and yieldingly return it to its lowered position, I employ la light -bar O10, pressed upwardly by a coil spring O11 at the pivotal support of the bar. v

As different bottles have slight-ly diii'erent forms and no liquid can escape either from the bottle or past the float N, I so construct a portion of the camway G4, which forces downwardly the pistons in the several measuring chambers, that the piston when it reaches approximately the Y end of its stroke, will be resiliently operated. For accomplishing this, I provide the construction illustrated particularlyi'n` Fig. 3, which includes a vertically-movable bar I, having a camway section P1 at its lower end and substantially in alinement with the main portion of the camway G4. The bar P is mounted directly above the lifter O and is f so `supported upon two'f pivoted armsIv2 and P3 carried by the'- tramex A. One of these arms 1s connected to a spring P4, whereby the` camway section Pi is normally or'ced down- 5 ward-ly, and the 'opposite end. of this spring may be connected to ai rod P5, having a nut I6 to facilitate the adust-ment-of the tensionv After they neck of the bottle has been completely filled mechanism comes into opera tion or withdrawing acertain amount of 'liquidto lowerthe level to a predetermined distance below the mouth. This mechanism, as shown particularl in Fig. 4, includes a suction-'piston R, adjacent-each pipe I1 and vertiiza-lly movable with: a small c linder R1 carried by" the' ainge C5. Each piston is secured to a pistbn rod R2, and each piston rod' has a bracket R3, clamped thereto and carrying a roller R4. This roller may en- Gage with acamway R5, securedl to the main Irame A. The upper 'end of the` cylinder R1 is in open communication withthe upper end 'of' the pipe I1, and the camway 1s so disposed that the piston is drawn downwardl tdwithdraw liquid `from the'upp'er endg o .the pipe Il after the valve H is closed and while the' pipe I isbeing lifted out of the bottle.A ToA prevent rotationof the piston rod' R2, al guide rod R (see Fig. 2) is preferably ernployed, and is so disposed as to extend through a portion of the bracket R3. Each suction piston R is so constructed that it works' equally well in both directions, so that during thedownward movement of the piston, liquid is positively sucked out of the pipe I1, while upon the return movement 0T the piston', the. liquid vis positively'forced into said pipe. l

In Fig. 3, I haveillustra'teda developedexterior view of themachie with the casing removed, so' that `the course of the bottles and the steps in' the operation mary be more clearly disclosed. The machine is capable of receiving eight bottles at one time, but as there is always one space vacant at the en# trance side of the machine, the filling operation is carriedi on in seven steps or stages, numbered as I to VII, inclusivegwin Fig. 3.

in the position indicated on the line I4 of Fig. 3. The valve I-I is in suchl a position that the liquid isA entering the filling chamber and the piston G and the' roller G3 have moved to their upward limiting' position.

tated to the position indicated' on line II,

rIfhe bottle enters the machine with the parts The roller R4 immediately engages the camway R5,= to raise the piston R', and the roller I3 engages the camway I4t to lower the tube I into the bottle. When the.. parts have' rothe valve H is rotated by the engagement of the studI H3 with the projection H.1 and the' roller G3 comes into' engagement with the cain G4 preparatory to forcing the piston G downwardly. The pipe I continues its downward movement until the position indicated inf line III is reached, and the piston G and roller Gf conti-nue their downward movement until the position indicatedin line VI is reached. The pipe I rea/'chesiits lowermost position shortly after the valveI'I is closed and as the liquid enters the bottle the pipe is graduallywithdrawn untili thev entire operation is completed and the bottle reaches the position indicated on the line VII. The piston R remains stationary iii-'omv the time the valve H is opened to'llthe botv` tle until after theA valve isclosedl.' As soon` as the valve is closed, whichv takes plac'e when the bottle is in the osition' indicated o'n the line VI, the lifter comes into-operation to raise the bottle into; engagement with the. packing N and the piston` It is brought downward as the pipe is brought' upward,- so that a predetermined quantity 9 E of liquid is withdrawn -from the bottle;-

E'ach and all of the bottles as they are fed into the machine and-come to the position indicated on the line II, contact with. the

plateA M, which controls the operation of the T00 =successive steps. Incase any space in the spider C2 is leftv vacant by the' failurev oi Ethe bottle-delivering means, the plate swings inwardlyI and permits thev plate Ml* to swing outwardly against the wal-l of the casing;v This movement of the plate re--4 movessections ofthe canrvvays` G4 and: Il*

and the stop'Hf from. the path of the appreaching rollers and-'the projection Hl, respectively, so that said rollers passy directly 4through on tothe opposite side o'f the -cam-4 way and are unaffected by thelattr. ,TH-us,

the piston G, pipe I, and. valve H, ofthe corresponding space, remain inactive throughout the circui Having thus described my invention; I
