To all whom it 'may con/ccm:

Be it known that l, AnoLPn SCHNEIDER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in BottleFilling Machines, of which the following is a specification.

The present invention relates to a machine lor bottling carbonated waters`and other beverages which it is necessary to bottle under pressure; and the objects of the present invention are, to provide means whereby the placing of a bottle upon the bottle support will actuate the filling mechanism, so that in case the operator fails to place a bottle upon the support no actuation of the filling mechanism corresponding to this pan ticular support is possible: to provide a shiftable member 'which is adapted to be operated by the placing of a bottle on the support to bring it into position to contact and operate the valve mechanism for actuating the sealing head and filling tube into filling position; to provide means forautomatically retracting the sealing head and filling tube from engagement with the bottle after the table has been rotated a preflctermineddistance; to provide means for 'adjusting the position ot the shiftable member, so that the lowering and raising of the tilting tube 'and sealing head may occur at any time desired with respect to the rotation of the table upon which the bottles are su poi-ted; to provide means for automatically returning the shifta'ble member to normal.

position; to construct passageways from a valve for controlling a medium under ressure to raise and lower the sealing hea and filling tube; to locate a fixed head within the cylinder which will serve as a backing tor the medium under pressure to act against, to lower the sealing head and raise the piston; to provide a series of tubes interior of the cylinder for conducting the medium into the cylinder, to raise the piston and lower the sealing head; to provide a connection between the pistonv and the sealing head, whereby the upward movement of the piston will impart an upward movement to the sealing head; to provide means for automatically establishing communication be-4 tween the liquid in the tank and filling tube when the filling tube shall have descendedA a predetermined distance; to construct telescopin tubes which provide a. passageway throng the cylinder to permitair to flow from the tank to the bottle, or vice versa; to establish an equalization of pressure bctween the tank and the bottle; to construct a cap iipon the upper end of the cylinder, which is provided with passageways to conduct air` from the bottle into a passageway leading to the tank, said cap being also provided with a passageway to permit liquid to enter into the interior of. the cap from a passage exterior ofthe c vlinderleading from the tank to a member having a passage for liquid therein, located exterior' of the tank, for conducting liquid from the tank to a passageway leading to the filling tube; ,t0 provide valve mechanism which is carried by the cap, which will serve to control the passage of medium into and out of the cylinder for raising and lowering the sealing head, and which will .also control the passageway for air between the bottle and the tank; to utilize the sealing tube as a valve member for preventing passage of liquid thea-cinto before the tube has reached the proper position within the bottle; to provide means for automatically deflecting the bottle from the table onto a bottle chute; and to means for retracting said detiecting means and' locking it in inoperative position.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In certain bottledilling mechanism heretofore constructed it has been the practice to operate the filling mechanism at a predetermined period with respect to the rotation of the table upon which the bottles are carried. This operation of the filling m'echsb nism would take place irrespective of whether a bottle were in position beneath the filling mechanism or not; hence, 1f through inadvertance the operator should neglect to tion, the fi ling mechanism would descend and alwaste' of liquid Wonldensuc, owing to place the bottle in'proper posi-- the" absence of the bottle from its proper position.

In ,the structure o'f the present invention, the lacing of the bottle upon its su port on 4t e rotatable table moves a shi table member into position where it contacts valve .'mechanism and actuates the llng mecha-` nism; hence, if the bottle is not placed in position, the shiftable member is not moved and the valve mechanism is not actuated, so that no operation of the filling mechanism results and no waste of liquid occurs through the operation of the filling mechanism at times when a bottle is not in the propery position to receive the liquid. lt has also been the practice in bottle-filling mechanism to move the bottle up into position to contact the sealing head. This upward movement of the bottle in some insances caused the bottle to ti during the movement, hence it was not brought into register with the sealing head and no filling operation took place. It was furthermore necessary in devices operated on that prin- 4ciple to employ an air pump or some other suitable mechanism for raising the bottle, and to also employ mechanism for lowering the filling tube into the bottle. In the present structure, the bottle remains stationary and the filling tube and sealin head descend to meet the bottle; thus any anger of tipping the bottle is avoided; and, furthermore, the mechanism necessarily emloyed for raising the bottle is entirely elimmated, thus materially reducing the complexity of the machine and the cost of con- -structlon and operation.

In the drawings, Figure 1 is a front elevation of lthe completed machine; Fig. 2, a plan View; Fig. 3, a detail sectional eleva- .tion of the bottle support the shiftable member for actuating the Valve controlling the fillin mechanism, and the connection between ,t e bottle support and theshiftable member, and showing the shiftable member in tperative position; Fig. 4, View similar to ig. 3,'showing the shiftable member in non-operative position; Fig. 5, a'detail plan View showing the bottle support and the shoe which is contacted by the arm on the bottle support to operate the `sliittable member; Fig. 46, a` sectional elevation' of vthe cylinder and its interior mechanism, and showlng the piston and sealing head in raised position; Fig. 7, a View similar to Fig. 6, showing the sealing head in its lowered position and the cylinder and filling tube partially lowered; Fig. 8, a view similar to F ig. 7, showing the piston and filling Itube in its lowermostposition; Fig. 9, an

The device comprises a base 24, 'extending upwardly from which is a tubular support 25, upon which is mounted a table 26 and a tank 27. The construction of the tubular support 25 and the manner of connecting the same to the table and tank, as well as the manner of conducting pressure and liquid through the support, are all shown andidescribed in Letters Patent No. 863,884, issued to me August 20, 1907, and the table 26 is rotated by means of suitable mechanism 2S. Mounted upon the table 2G arc a plurality of bottle supports 29, each coinprising a member 30.0f shoe-like formation, which is provided along one side and at its rear with an upwardly extending wall 31, provided with a slot 32, the other side and the front of the support being unobstructed to -`permit ot' the passing of the bottle out therefrom and in thereto, as will be more fully hereinafter explained.

Resting above the lloor :lll of the bottle support is a plate Si; and positioned in the space l between the floor of the support and the lower edge of the support is an outwardly extending contact stem or arm 3G, which is pivoted at 37 and is formed with a head 3S adapted to project through a slotA 39 in the floor ot the support. As shown in Fig. 4, under normal conditions, the weight of the arm 36 will tend to holdV it in the downward position shown in Fig. 4, whereby the head will be projected through the slot 39 and raise the plate 34 somewhat above the 'floor 33; but when a bottle is placed upon tht` plate 34, it will be moved into the position shown in AFig. 3, and the head 38 will bc forced through the slot 35), thus swinging the outer end of the arm -lt into the osition shown in Fig. 3, Where it will stl-il e a contact and operate the shiftable member to actuate thc lillinf mechanisin. 'lhe operation, however, wil be moreV fully setv forth hereinafter.

Positioned adjacent to the structure is an upright post 40, which terminates at its upper end in outwardly extending, diverging arms 41. The arms 4l are adapted to receive a structure 4Q, which extends downwardlytherefrom and comprises an 4clongated stem or shank 3, with which are formed sleeves 44 and lt. which serve as a mounting and guide for the slidable rod 4G. 'lhc rod 46 has secured to its lower end a inder, as will be more fully hereinafter ex- Carried by tli'e sealing head 60 is a tube I63, which 1s in communication with a ceases shoe 47, which is provided with a sloping surface 48, and the sloping surface 48 hes within the path of travel of the arm 36 when said arm is raised to-the position shown in` Fig. 3. Hence, the arm will strike the sloping surface 48, and, since the arm is held 'in fixed position by the wei ht of the bottle, it will force the shoe 47 ownward, thus lowering the rodsit.

Attached to the upper end of the rod 4G is a link 49, which is attached to a finger 50 pivoted to the structure 4Q at l. the finger 50 forming in fact a shiftable member which is thrown by the movements of the rod 46 into and out of position to contact the valve and operate the filling mechanism. Secured to the rod 4G is a collar 52, interposed betweenY which and the Asleeve 45 is a spring 53 fe; forcing the rod .46 upward to normal position alltel-,the arm 36 has passed across the surface of the shoe 47. As shown in Figs. 3 and 4, the sleeve 45 is formed with a downwardly projecting lug 54, which serves as a hacking for the shoe 47, to prevent its swinging out of position during its upward and downward movements. l

Secured to the tank it? are a plurality of cylinders 55, each secured by means of stems 5610 the tank 27. rl`hc interior formation of the tank may be of the kind described and shown in my )ending application SerialNo. 560,111, filed iMay 9, 1909, or any other well known and suitable forni of structure. lo sitioned/upon the upper end of the cyl'ur der is a cap 5T. and upon the lower end of the cylinder is a cap 5H; and the stems 5G are formed integral with the cap and serve to connect the cylinders rigidly to the tank,.aud also serve for the conduction of air and liquid into the interior of the cyl- It will be understood that a, plurality ot' bottle supports are used and that a cylinder is positioned in vertical alinement with each bottle support; but since each of the bottle supports and cylinders and the 1iecha nism interior of the cylinders are alike in every respect, detailed description of ,but one bottle support and one cylinder is all` that is deemed necessary at this time. The cylinder has positioned in its interior an eularged tube 59. secured to the lower end of which'is a sealing head (i0, which is formed with a funnel-shaped mouth 61, positioned in which is a semi-circular ring of sealing.,r material 62. The general construction and arrangement of the centering guide, 62,f however, are well knownA in the art and deL' tailed description thereof is not deemed necessary in describing the present invention.

assage 64communicating with a chamber 65,

-members for a piston 76.'

in which is positioned a oat G6, and the chamber communicates at its opposite end with a passage G7, which is in communication with a passage (58 merging into the mouth 61. The tube G3 is adapted to telescope within a tube 69a, one end of which is secured within a fixed head 70, located in the interior of the enlarged tube 5S), but held against vertical movement with respect to said tube. The opposite end of the tube GQ is secured to the upper cap 57, and communicating with the upper end of the tube 6D 1s a passageway 70 which extends forward, as shown in Flg. 1Q, and thence upwardly to communicate with a passage 71 in a valve plug 72; and extending Within the cap 57 and above the valve plug 72 is a passageway 73, which extends parallel to the passage 70; and the passage 73 communicates with a passageway 74 in the stem 5G extending from the cap 57.

The passageway 74 communicates with the interior of the tank 27 and serves to conduct air from the bottle into the tank or out of the tank to the bottle, as the case may be, in order to secure an equalization of pressure between the tank and bottle. The air passes through the passage 74 into the assage 73, thence through the passage 71 o the valve member 72 when said valve member is in proper position to the

passages

71 and 73; and after passing through the passage 7l the air passes through the passage '70a and into the tube GSP; thence through the tube 63 into the passage (34 and through the chamber G5 into the passage G7 andthence through the passage (i8 into the bottle. '1 hus, when the valve 72 is turned into proper position, a Y free passage is established between the bottle and the interior of the tank for the conduction of air from the tank to the bottle, or from the bottle to the tank; and the Iloat is provided so that after the filling operation liquid will not be forced through the cl1arnber and up into the passages 64 and into the tube 63, the float rising when `liquid is forced into thechamber G7 and seating itself to dose the passage 64. 1

`Oppositcly disposed with respect Ito' the v tube 69 is a tube 75, which has one end secured to the fixed head TOand the other end secured to the cap 57, the two tubes 69 and 75 coperating to form a support for the head 70, and also coperating to form guide 'Ihe piston 76 is provided centrally thereof with a chamber 7, into which are entered the adjacent ends of an up er filling tube 78 and a lower fill-- Vmg tube 9; and positioned within the cham;

ber 77 is a plate 80, which is provided eentrally thereof with a depending tapered lug 81, which is adapted to enter into the upper` i end of the lower filling tube 79 and close the same, thus preventing the passa e of liquld from the upper to the lower gli tube at all tilnes save when the valve member 81 is unseated from the upper end of the lower filling tube 79. t

The plate 80 is' provided with oppositely disposed, downwardly depending stems 82, which extend below the lower edge of the piston and are adapted to Contact the fixed head when the piston has reached a. point adjacent its lowerniost position and unseat the valve meniber 8l in the manner shown in Fig. 19; and coil springs S3 are provided for returning the stems 82 to their normal position after the piston has been raisedyto draw the ends of the stems free of the fixed head 70. Thus, when the piston has descended toa point approximately its farthest position downward, the valve between the upper and lower filling tubes will become unseated, thus permitting liquid to low from the upper tube into the lower tube and thence into the bottle. In this manner, leakage of liquid is prevented and the flow thereof permitted onl)r at a time when the lower filling tube shall have been inserted in proper position within the bottle.

lositioned within the tube and secured within the eap 57 is a tube 84, which, as shown in Figs. (i, 7, S and t), is of a smaller diameter than the tube 75, wherebyv a space H5 is provided between the two tubes. The tubi` To is provided with openings 8G located adjacent to and 'above the fixed head 70. and the tube 8l extends through the fixed I head and is in connuunit-ation with the spare below said head. Hence, when pressure is admitted to the interior ot' the tube Set. it will pass down and enter into the spare below the fixed head 70, and will thus act against the upper surfaee S7 of the sealing head. to force the sealing 'head downward. At the same time that pressure is admitted to the tube 8l, pressure will be admitted to the .space 88 between the lower face `of the cap 57 and the upper face of the piston 7 6,

,.thusl forcing the piston downward 4simultaneously with the forcing of the sealing head downward. The sealing head will con'- tinue downward until the ring 62 is seated around the mouth ot' the bottle. This will nerve 'to cheek an)Y further desrent of the sealing head` but the piston will continue to :lt-.trend until the stems S2 Contact the fixed head It)` at which time the lower filling tube shall have entered into the bottle the primer distance to permit the flowing 0f liquid thereinto. l

Carried bj.' the tube 59, upon the upper Vend thereof', as shown more clearly in Eig.

7, is a hanged ring 89, which serves as a connection between the piston and sealing head, so that upward movement of the pistondraws the sealing head upward simultaneouslj,YAY therewith. lVhen an upward movement 'ofl the piston is desired, pressure is admitted into the space' 85 between the eeagaee the rap 5T; and the tube 90 is provided, ad-

jarent its lower end, with an opening 91', which is in roniniunieation with a passage 92 formed in the cap 57, which passage eornuiunieat'es with a tube J3 extending upon the outside ot the Cylinder, said tube being in Communication at its lower end with a passage 94 formed in the stein 56. The stem t' enters the tank Q7 at a point. so that the liquid contained in said. tank will flow through the passage ill and tube 93 into the passage 92, the foreing upward of the liquid in this manner heilig easiliv accomplished by reason of the pressure which is eonstantl)y ou the liquid in the tank.

l'he upper filling tube 78 also forms a closure to prevent the passage otl liquid through the opening 91 into the interior of the filling tube at all times save when the filling tube has been lowered to the proper position within the bottle. lVhen such positionhas been reached, the upper edge 95 of' the filling tube will be elear of the opening- 91, so that liquid can flow through said opening into the filling tube, and thence downward and through the chamber 77 in the piston` into the lower fillingl tube 79, and thence into the bottle. The filling tube itself thus serres as a valve to prevent the passage of liquid thereinto at all times, save the proper one. 4

lt of' course. evident that during the filling' operation there will be a column et liquid extending from the opening 91 to the bottom of the filling tube, but when the piston starts upon its upwai i movement the valve 8l will seat itself, thus cheeking the flow of liquid ilroni'the upper tube to the lower tube and trapping a certain amount of liquid in the upper tube. `Thus, the initial portion of the liquid entering the bottle will tall only from the chamber 77 to the lower end of the tube and will not. enter the bottle4 with the fviolent rush that would oeeur if it were to fall the whole distance through the upper and `lower filling tubes. ltnrtherniore, the liquid will not continue yto descend for any great length of time after the piston has started its upward movement.

str

.Pressure is admitted to the tube 84 and to the space 85,v between the tube Stland 75,

The passageways are controlled by the valve 72, which is provided in addition to the assage 71 with

passages

96 and 97, adapte by different manipulations of the valve to be brought into conununication with a supply port 98 and an exhaust port 99. Communi cation to the tube 84 is provided through the medium of a passage 100 communicating with a passage 101 adapted to be brought into communication with the supply port 98,

through the medium of the passage 96 when the valve is turned into the position shown in Fig. 15. Also. in communication with the passage 101 is a passageway 102 leading to the space between the bottom of the cap 5i' and th'e piston 76. valve is turned into the position shown in Fig. 15, pressure is admitted through the

passages

101 and 102 above the piston T0, to drive the piston downward. so t at pressure is admitted simultaneously to the tube 84 t0 drive the sealing head downward, and tothe space above the piston to drive the piston downward. iut when the valve has been moved to the position shown in Fig. 16, the the passageway 101 is brought into communieition with the exhaust` port 99 through the medium ot' the passage 96 in the valve in anber: and the passage 97 is then brought into couummieation with the supply port 08 and a passage 103. which communicates with the interior of the tube 75L-and thus pressure is admitted through the space between the tube T5 and tube 84. from whence it passes out through the openings 80 to act upon the lower t'aee of the piston and torce the pis ton upward.

.\s will be noted in Figs. 15 and 1.0, the valve is located to one side of the center of the c vlinder. and the passages enter into the c vlinder at a point approximately the eenter thereof'. Thus the valve is in a position where it does not in any way interfere with the passage of the filling tube up and down through the center ot' the ca p. 'l'he valve is provided with a stem 104. to which is at,- tached a wheel 105 comprised ot' a plurality ot' fingers ltlf: and these fingers are ada-pt,- ed to be contacted by the finger 50 when it` is raised into proper position by tho placing ot' a bottle upon the bottle support.

.\s shown in Fig. 1, the fingers or shiftalile members 50 and the mechanism for operating said fingers are placed upon either side ol' the post 10. one of the fingers ofthe pair ot' lingers serving to throw the valve into the position shown in Fig. l5 to admit. pressure to lower the sealing head and piston. and the other of said lingers serving to throw the valve into the position shown in Fig. lli. where pressure is admitted to raise the piston. .\\nd since each ofthe lingers 5U and the mechanism for operating the same are exactlyY alike in every partieular, a detailed description ot' but one is all that has Hence, when the been deemed necessary. The? supply port 98 may be connected in any suitable manner to a suitable source of pressure supply, as, for instance, an ordinary air pump; and this connection may be made through the interior of the tubular support 25, as is shown and described in Letters Patent. No. 863,884, granted to me August 20, 1907, or in any other suitable manner.

As shown in Figs. 22 and 24, a chute 106, eomprising an adjustable wall l107 and an arm 108, is provided with a. forked end 109 adapted v.to register with the slot 32 in the wall 31 of the bottle support. The arm 108 is hinged at 109,` and attached to said arm is a rod 110, which passes through a lug 111; and the lug is provided with a locking memberv 112 adapted to enter into recesses 113 in the rod 110. to hold the arm 108 in a restricted or extended position, where it is hrpught into and out; of the path of travel of te'bottle lying upon the bottle support: andthe chute 106 is held against rotation about the post 40 by means of a set screw 114. or other similar locking device.

lVhen the arm 108 is in the position Shown in Fig. 2Q, it will contact the bottle 115 resting upon the bottle support and force it against the wall 3l of the bottle support; and. as shown, this wall is positioned at an angle so that the bottle when caught between the arm and the wall will be'forced outward along the wall and onto the chute 100. since the support is rotating and the arm remains fixed. But when the arm is drawn back into the position shown in dotted lines in Fig. 22. it will then lie outy of the path of travel of the bottle upon Ythe support. so that the bottle will pass thereby and will not he forced onto the`chute 10G.

The operation will be understood from the foregoing. but briefly is as follows: 'hen a bottle is placed upon the plate 34, the plate is t'oreed downwardly, as shown in Fig. 3, swinging the arm liti upward into position where its path of travel will cause it to contact the sloping surface ttl of the shoe l?, thus depressing the shoe and drawing the rod 4t', downward. lowering the link lt), swinging the linger 50 upward into position to contact the wheel 105i, and operating the valve 7'2 into the 'position shown in Fig. lo. where pressure is admitted to the interior of the cyliudtepto lower they piston and si aling head; and-the sealing head continues itsl descent uuLil the ring 02 seats itself around the head ol the bottle, after which further descent of the sealing head is checked. The piston will continue, to move t downward until the. stems 82 contacty the lixed head. as shown in Fig. lf). When this point has been reached. the filling tube will be in the position shown in Fig. 8. where the top of the tube lies below the opening ttl, and liquid will enter from the passage 9i. into the upper filling tube 78. The contacting of the stems S2 with the head 70 will unseat the valve S1 and permit liquid sealing head to flow from the upper tube 78 into the lower tube 79 and thence into the bottle. The mechanism will remain in this osition until the table has been rotated suiiiciently to bring the arms 36 into engagement with the oppositely disposed shoe 4]', to depress said shoe and more the oppositely disposed finger 50 into position to actuate the valve into the position shown in Fig. 16, at which time pressure acting againstthe upper face ofthc piston and the upperface of the will be exhausted through the exhaust port 99; and the supply port 98.will be brought into comnmnication with the passage4 103 and pressure admitted to the space 85 between the tube 84.- and the tube 75,from whence it will pass through the opening 36 to act against the lower face of the piston and force the piston upward. And the piston, after moving upwarda predetermined distancc, will contact the flanged ring 89 `andr more the tube ,'59 upward, thus carrying the sealing head 60 upward until the flanged ring 89 contacts the cap 57, when the device will be in the position shown in Fig. 6, which is the normal position.

iVheu the valve 72l is turned into posit-ion to admit pressure to lower the piston andy the passage 71 will be brought sealing head,

with the

passages

73 and 70% into register 4thus establishing communication between the tube 69 and the passagei'fi, and permitting air to How, to equalize the pressure between the bottle and tank. And this equalization will be maintained until the valve 72 is turned into position to admit pressure to the cylinder to raise the filling tube, at which time the passage 71 in the valve will be brought out of colmmmieation with the

passages

73 and 70 and communication between the tanlr and the bottle broken. v

rFlic liquid which remains in the lower filling tube, after its retraction from the bottle, is held from iiowing out therefrom by the pressure of air upon the lowerend thereof, under the old and well known principle ot' sustaining a column otliquid within the tube by means oi' the air pressure on the lower cuchillo upper end, of' course, being liermctirally scali-d.

I claim:
