To a/ZZ wtont it' ritrty concern:

Be it known that I,FRANK C. KELLER, aA

citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and `useful Improvementsin BottleFilling Machines, of which the following is a specification, reference being had to the accompanying drawings,forminga part thereof.

The main objects'of my invention are to facilitate therbottling of carbonated or effervescing beverages or liquids, to avoid foaming and loss and deterioration of such liquids in the operation of bottling, to economize space, and generally to improve the construction and operation of apparatus of this class.

It consists in certain novel features in the construction and arrangementof component parts of the apparatus, as hereinafter particularly described,and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several ligures.

Figure l is a view, partly in side elevation and partly in vertical medial section, ot'a bottle-iilling machine embodying my invention. Fig. 2 is a side elevation and partial vertical section, on a greatly-enlarged scale, of a portion of the rotary reservoir and one of the bottle-holders. Fig. 3 is a horizontal section on the line 3 3, Fig. 2. Fig. isa vertical section on the line 4 4, Fig. 3; and Figs. 5 to 8, inclusive, are detail views ofthe mechanism for grasping and holding the neck of a bottle in position for filling, Fig. 5 being a horizontal section on the line 5 5,Fig.6, Fig. G a rearelevation and vertical section looking from the right with reference to Fig. 2, and Figs. 7 and S sections on the lines 7 7 and 8 S, respectively, Fig. 2.

A designates a floor-stand, which may be conveniently made in the form shown in Fig. l, with a ring ct at the upper end, in which is secured an,upwardly-extending tube ct and in line therewith a downwardly-extending tubular bearing a2, having a lateral liquidsupply connection B within the ring ct.

C isa closed reservoir, preferably of cylindrical form, for containing the liquid to be bottled and compressed air or gas above the liquid. It is provided on the underside with tral vertical axis.

ot the cup E.

bers, which are arranged side by side and a tubular stem D, which extends loosely through the tube ct of the door-stand and is supported at its lower end in the bearing a2 upon a packing-ring or washer. The boss on the lower end of said stem turns in the bearing The reservoir is thus firmly supported, but allowed to turn freely around its cen- Said reservoir is provided with a detachable cover C, recessed in the under side and formed on the upper side with a central upwardly-projecting tubular neck c. In the neck c is fitted an inverted cup E, having a perforated head at the upper end and an outwardly-extending flange at the lower end. e is a cap threaded upon the upper end of the cup for securing it in place in the neck c and for closing the upper end of said neck. A packing-'ring interposed between said cap and the upper end of the neck forms avgas-tight joint. p

F is a pipe-couplingand val ve-chamber centrally and loosely suspended from the head It is formed with two chamcornmunicate with each other. One of said chambers is open at its lower end and in it is secured the upper end of a tube G. The other chamber is formed at its lower end with a port and valve-seat and is provided at its upper open end with a screw cap or plugf. A valve H, contained in the latter chamber, normally closes said portand has a stem projecting downwardly through it. The lower end of the tube G is secured in one member g of a coupling located near the bottom of the reservoir C. In the lower end of the same coupling member is secured the upper end of a small tube I. To the other coupling member g is attached the upper end of a tube J, which extends downwardly therefrom inside of the tubular stem B and outside of the tube I throu gh the tubular bearing a2 into a chamthe bottom of the reservoir, into which the' lupper end of the stem D is screwed, is fitted tto turn in the upper end of the tube 0.',while with the supply connection L. In the chamber 7s is loosely tted a flanged sleeve 702, having an opening through the side and closed at its lower end. The lower end of said chamber k is closed by a gland k3, which rests in a socket in the upper end of a screw 764,

zo-and is provided with a central tubular stem m, open at both ends. The stem m is loosely fitted over a collar g2 on the upper end ofthe pipe G and the coupling member g and is adapted to move freely up and down thereon.

N is a tube attached at its lower end to the coupling member g and communicating through a passage therein with the upper end of the tube J. It extends upwardly from said coupling member close to and parallel with the stem m into the upper part of the bell M, where it opens. A weighted lever 0, fulcrumed to an arm on the lower end of the cup E, counterbalances the bell M.

P is a valve normally closing a waste-passage c in the cover of the reservoir C. It is engaged by one end of a lever P, fulcrumed to an arm on the lower end of the cup E and engaged at its other end by a groove or anges on the upper end of the tubular stem m.

The reservoir C is formed with a number of outwardly-projecting necks c2, in the outer ends of which are pivotally mounted bottleholders and siphons. Each of these siphons consists of a bent tubeQ and a nozzle Q. The tube Q, which is bentdownwardly at both ends, is formed or provided at its outer end with a recessed head q, in which is fitted a rubber or other suitable packing-ring for sealing the mouths of bottles held therein, and at itsinner end said tube is provided with a valve -chamber containing an upwardlyclosing winged valve q', the downwardly-projecting stem of which is loosely 4litted in a iianged sleeve q2, which is loosely fitted and movable endwise in said valve chamber. Said sleeve is provided for the purpose of eX- tendiug the intake end of the Siphon-tube close to the bottom of the reservoir C when said valve is opened. Each tube Q is formed or provided on opposite sides with trunnions fitted and adapted to turn in bearings in an internally screw threaded flanged ring c3, which is fitted over the outer end of one of the necks c2 on the reservoir C, as shown in detail in Figs. 3 and 4. The space between said tube and the neck through which it passes is closed by av flexible diaphragm Q3, of rubber or other suitable material. This diaphragm is secured around its inner edge to the tube Q between a shoulder and a ring threaded upon said tube, and at its outer edge it is clamped between the end of the neck c2 and the iianged ring c3 by means of an externally-threaded and winged ring c4, titted on the outside of said neck. By this means the siphons are made readily detachable Jfrom the reservoir for the purpose of cleansing, repair, or inspection. The nozzle Q passes through a central opening in the head g and the packing-ring contained therein and is secured in the outer end of the lower passage in the tube Q.

R is a valve normally closing a passage in each tube Q leading from the gas-space within the reservoir O into an annular space in the head q around the upper end of the nozzle Q. This valve is loosely held in a chamber which is formed in the outerend of the tube Q and closed by a screw-cap, aording easy access thereto. A lever r, fulcrurned in the gaspassage of the tube Q, engages at one end with the valve R and projects upwardly at the other end from said passage into the neck c2, with which it engages when the outer end of the si phon is depressed. To the lower end of an arm g4, on each of the heads q, is adjustably secured a bottle-rest S, adapted to support a bottle in proper position for filling on the adjacent nozzle Q. v

T T are jaws hinged together and movable vertically a limited distance upon a tube t, which is loosely guided and movable vertically in an opening in the arm Q4, approximately parallel with the nozzle Q' of each siphon, as shown in Figs. l, 2, and 6. These IOO jaws project from said tube outwardly on opposite sides of the nozzle and are adapted to grasp the neck of a bottle placed thereon, and when raised, as hereinafter explained,

to force the mouth of the bottle upwardlyV against the packing-ring in the associated head q, thus hermetically sealing the bottle while it is being filled. The tube t is provided on the back side with an upwardly-projecting wedge t, which is adapted when forced upwardly to pass between lugs t2 on the rear ends of the jaws, as shown in Figs. 2, 5, and 6, and thereby force the front ends of the jaws together against the neck of a bottle, at the same time moving them upward against the shoulder on the bottle-neck and forcing the mouth ot' the bottle against the packingring in the head q.

A lever U, fulcrumed to the lower endKV of the arm g4, is pivoted at its outer end to the lower end of a rod u., which passes upwardly through the tube t and is retained therein by a cross-pin u at its upper end. A spring u2, surrounding a reduced part of the rod u and bearing at its lower end against a shoulder thereon and at its upper end against a ring or shoulder in the upper end otsaid tube, constitutes, with said rod and tube, a

yielding connection between the lever U and the wedge t', whereby the closing of the jaws T and their upward movement may be arrested before the lever U reaches the limit of its movement, and allowance is made for variation in the bottles. The inner end of the lever U, which may be provided with an antifriction roller ug, bears against the camshaped rim of a ring V, which is threaded and vertically adjustable upon a cylindrical rim V on the bottom of the reservoir C. That part of the rim of the ring V with which the levers U en gage is so shaped that when a bottle placed on one of the nozzles Q against the associated rest S is pressed downward and inward the outer end of the lever U will be thrown upward, closing the jaws T against the neck of the bottle and moving them upward in engagem ent with the shoulder thereon until the mouth ofthe bottle is tightly pressed into the packing-ring in the head q.

To each arm q*L or lever U near its fulcrum is pivoted a lever W, which engages at its outer end with the jaws T, limiting their downward movement on'the tube t, and at its inner end with a part of the rim of ring V, which is concentric with the trunnions on which the bottle-holders and siphons swing. The thumb-screw s, by which the lever U is pivoted or fulcrumed to the arm q", may serve also as a clamping-screw for holding the bottle-rest S in adjusted position on the arm g4, as shown in Figs. 7 and 8. The opening in said rest, through which said screw passes, is transversely elongated to permit of the adjustment of said rest, which is pivotally connected by a pin or stud with the arm q* above said opening, the arm and rest being formed below said opening with interlocking teeth or projections.

My improved machine operates as follows: The pipe or hose leading out of the cask or receptacle containing the liquid to be bottled being attached to the liquid-supply connection B, and a pipe or hose leading from a reservoir containing compressed air or gas being attached to the connection L, the cock Z is opened and gas under pressure is allowed to pass through the chamber Zt and tubes .I and N into the gas-holding bell M and reservoir C, pressure in said reservoir and bell, which are now in open communication with each other, being the same and indicated by the manometer or gage X. (Shown in Fig. l.) The cock Z is then closed and the liquid to be bottled is admitted through the connection B and tubular stem D into the reservoir C. As it rises therein it immerses and seals the lower edge of the gas-holding bell M, as shown in Fig. l. The level to which the liquid rises in said reservoir is determined by the volume and pressure of gas contained in the bell orholder M, and these are regulated by means of the cocks Z and Z'. In practice the reservoir from which gas is supplied to the machine is also connected with the cask or receptacle containing the liquid to be bottled. If vthe cask or receptacle containing the liquid is placed at about the same level as the reservoir() of the bottling-machine, the same gas-pressure may be supplied vto it and to the bottling-machine; but if the liquid-receptacle is placed above the machine it is necessary to provide the connection between the gas-reservoir and the liquid-receptacle with a reducing-valve. In case the liquid does not rise in the reservoir C to the desired level,as indicated by a glass gage, (not shown,) part of the gas entrapped in the bell M is allowed to escape by opening the cock Z', thus reducing the pressure in said bell and allowing it to descend by reason of the greater gaspressure outside. The descent of the bell opens the waste-valve P and allows someof the gas con tained in the reservoir C to escape, thereby reducing the pressure outside of the bell and allowing it to resume its original position and said valve to close. The reduction in the'volume of gas contained in the reservoir C and bell M allows the liquid to rise therein. In case the liquid should rise too high the cock Z is opened, allowing more gas to pass into the bell M and increase the pressure therein. The bell is thus caused to rise and open the valve H, which admits gas into the reservoir outside of the bell through the tubes G and I and branch passage Z2, thus increasing the pressure outside of the bell and causing it to descend and the valve H to close. This increased pressure in the reservoir C,.both inside and outside of the bell M, causes the liquid-level to fall. Liquid and gas supply connections having been made and the level in the reservoir C adjusted, as above described, the operator, standing on one side of the machine, places a bottle on one of the nozzles Q against the associated rest S and turns it downward and inward, as shown at the right in Fig. 1. This operation opens the valve R, allowing gas to flow into the bottle around the nozzle Q' until the pressures in thebottle and reservoir are equalized. When the counter-pressure thus produced in the bottle, plus the weight of the valve q, is equal to or slightly greater than the pressure of the liquid, said valve, which was closed and held in that position by the unbalanced liquid-pressure, will be opened, allowing the liquid to flow through the siphon Q Q into the bottle by gravity. The gas-pressures in the bottle and reservoir being the same, there will be no foam or loss of liquid, no liberation of gas, and no deterioration of the liquid in consequence thereof. In starting the machine when the siphons are empty, each bottle when moved into position is suddenly pulled downward, the spring u2 permitting a sufficient movement of the bottle to draw enough liquid into the siphon to fill and start it. After the siphons are once filled they will remain so until the reservoir C is emptied. As each bottle is placed in position to be filled it is turned with the reservoir C to one side, another bottle is placed in position, and soon IOO IIO

IZO

until all the siphons are supplied with bottles. As the filled bottles return to the startingpoint they are turned upwardly and removed from the siphons and replaced by empty bottles. In theirpassage around the machine ample time is allowed for filling, so that the operator without change of position may remove fllled bottles with one hand while he supplies Itheir places with empty bottles with the other hand. Each bottle to be filled is placed by the operator on a nozzle Q and moved upwardly thereon until its mouth rests against the packing-ring in the head q, the jaws T being spread sufficiently to allow the shoulder on the neck to pass between them. The body of the bottle bearing against the support S is swung downwardly and inwardly, the initial movement thereof causing the cam-ring V to depress the inner end of the lever U and raise its outer end. This movement of the lever U forces the wedge t upwardly between the lugs t2 on the rear ends of the jaws, thereby closing the jaws against the neck of the bottle and then carrying them upward with it against the shoulder on the neck of the bottle. The mouth of the bottle is thus forced upwardly into the rhead q against the packing-ring therein, by which itis sealed. When the neck of the bottle is grasped by the jaws and its mouth is pressed against the packingring with sufficient force, the movement of the jaws and their actuating-wed ge is arrested and the spring a3 is compressed, permitting of the further movement of the lever U. The tension of said spring therefore determines the degree of force with which the jaws grasp the neck of the bottle and force :its mouth against the packing-ring, and the closing of the jaws, as well as their upward movement, will be arrested whenever, according to the size of the bottle-neck and the distance of the shoulder from the mouth thereof, which vary in different bottles, the resistance opposed to such movements of the jaws is suflicient to overcome the tension of said spring. The springs u2 are made of such strength or tension or are so adjusted that the jaws will not break or injure the bottles. The wedge is forced more or less between the lugs t2, according to the diameter of the neck of the bottle grasped by the jaws. The jaws are thus made self-adjusting within certain limits to accommodate the ordinary variation in the necks of bottles of any given size or of different sizes. After the mouth of the bottle is forced against the packing-ring in the head qsufliciently to seal it against the passage of gas the inner end of the lever r is carried by the continued inward and downward movement of the bot-- tle against the upper side of the neck c2, thereby raising its outer end and lifting the valve R from its seat, as shown at the right in Fig. l. Gas thereupon rushes from the upper part of reservoir C into the bottle until the pressure therein equals that in the reservoir. As soon as the pressure in the bottle is equal or nearly equal to that ofthe reservoir the valveI q falls away from its seat, allowing liquid to iiow from the lower part of said reservoir through the Siphon-tube Q and nozzle Q' into the bottle. The parts of the machine being so arranged and adjusted that the mouth of the bottle is at or near the level of the liquid within the reservoir C, the iiow of liquid from the reservoir into the bottle will .stop when the bottle is filled or nearly filled. The gas displaced by the liquid flowing into the bottle passes back through the annular space in the head q, around the nozzle Q', and through the passage in the upper part of the siphontube Q into the reservoir. Any material variation in the pressure or liquid-level within the reservoir O,which might otherwise result from variations produced by the operation of the machine in the volume of gas contained in the reservoir, is prevented by the automatic operation of the gas supply and waste valves H and P by the movable gas-containing bell M, as hereinbefore explained. When the bottle returns to the starting-point-after its passage around the machine,it is swung outwardly and upwardly and withdrawn from the nozzle Q'. The initial movement of the siphon in this direction releases the lever r and the valve R, which thereupon closes the gas-passage in the tube Q before the bottle is released by the jaws T and allowed to move away from the packing-ring in the head q. The further movement of the bottle carries the inner end of the lever U outward against the cam-ring V, thereby allowing'the jaws T to descend with the bottle until their movement is arrested by the lever W. The further outward and upward movement of the bottle withdraws the wedge t from the lugs t2, allowing the jaws T to open and release the bottle, which is then withdrawn from the noz'zle Q', leaving it in position to receive an empty bottle. The valve q', which may be closed or partially closed by the upper end of its stem entering the passage in the siphon when its inner end is turned down, as shown at the left in Fig. l, is instantly and completely closed and held closed by the unbalanced pressure on its under side as soon as the mouth of the filled bottle is released from the packing-ring in the head q until it is again unseated by the counter gas-pressure produced in another bottle, as above explained. A

The sleeves q2, extending the inner ends of the Siphon-tubes Q when they are lifted, as shown at the right in Fig. l, insure a supply of liquid to the siphons when the liquid-level in the reservoir is low and serve to remove nearly all the liquid from the reservoir whenever the operation of the machine is to be discontinued.

The machine is adjusted for bottles of different sizes by setting the rests S backward forlarger bottles or forward for smaller ones and by screwing the cam-ring V up or down. The latter adjustment simultaneously sets the IIO jaws T of all the bottle-holders and siphons, the raising of said ring lowering the jaws, while the lowering of the ring raises the jaws.

It will be observed that provision is made for easily and quickly gaining access to the various parts of the machine-as, for example, the siphons may be detached and removed by unscrewing the collars c3, and the valves l-I and P and the bell M may be reached by removing the cover C. This is of great importance for bottling beer and similar beverages in order that the machine may be frequently and thoroughly cleansed.

The machine is compact in form, occupying a very small-floor space, is easily and economically operated, and avoids waste and deterioration of the beverage or liquid to be bottled.

l do not wish to be understood as limiting myself to the exact details of construction herein shown and described, as they may be variously modiiied without materially affecting the operation of the machine or departing from the principle of my invention.
