Be-it known that w RICHARD Prerr, a

e subject of the German mperor, and WER- NER SUTER, a citizen of the Swiss Republic, residing at Zurich, in Switzerland, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following is a s ecificatio.

l This invention re ates to apparatus for filling bottles and other receptacles and comprises receptacle-'holders wh1ch are cariied by a horizontally rotatable frame and are' adapted to be lifted by meansl of a pressure fluid. y l i The object of the invention is that all operations for filling the receptacles, between the' moving thereof to the iill'er-heal und the depositing .thereof at the place of t'lelivery, are ,automatically performed, the control of the channels for the liquid and pressure fluid being' controlled by means of n singlel central' cock. By the rotation of the frame" these. channels are opened and closed as required'. t l

A further ob'c'ct of the present invention consists in a construction and arrangement whereby the supply ,and return of the prescotrolled by the said central cock. Two' linodifications of the invention are shown' in the accompanying drawing', in each of which the apparatus comprises' sixteen filling devices, but there may bein greater er" less 'number of these devices. The

sure 'u'id lifting the receptacles are also` 'apparatus shown in .Figures 1 to' 5 ifs' deslgned for working with compressed air as piessre Huid'.

Fig. l is a Vwfverticltl section of the cent''al cock, and shows in elevation two of 'the namely cn the left with s bottle f the bottle-lifting piston lowered.

Fig'. 8 isa horizontal section of the upper part of the filler'.

Fig. 9 shows in vertical section a modification for Working with water under pressure. Fig. 10 is` a cross-section on line 7--7 of Fig. 6.

Ih'the drawing, 1 represents appillar, to

uic upper end cf which the plug lci the central cock is fixed below a vessel 4 containing the liquid with which the bottles are'to be filled. The rotatable shell 3 of the cook is screwed to a rotatable pillarl and has :mns 5, which connect the shell' with valves in valve-boxes 6 for the liquid oW- ing to the filler-heads and air escaping from the bottles. y Each valve-box 6 has a filling pipe 28 and bottle-centering device 7.v

From the Vessel 4 channels 10 and 21 in the

plug

2 and 17 in the shell 3 lead, `respectively, directly to the bottle and tort-he valve-box 6. These channels serve for "the" supply of pressure fluid to the bottle and valve-box. In the latter the fluid opens valves Which allow liquid' to flow to the bottle and air to escape from the bottle. Liquid flows from the vessel 4 through channels24, 25 and 26 to one of the sixteen channels 27 in arms 5, and through one .of the vulves in the box 6 tothe pipe 28 and bottle.

Communicating w'i'ththe aioresaid channel' 17 is a channel 18 which divides into 'two' branch channels 1'9f and 20". The 'chalk' .nel y1li" leads to un annular channel 19b passing to the filler head 15 from which vthe fluid flows into the bottle. The channel 20 communicates with .a channel 21 (Fig. 6) one wall of which is formed by a vmembrane 22 dividing said chamber 21 from a cham- To this membrane is attached a metallic member 23b which is acted on by a spring' 23 at one side and hasfixed to its' other side pistons 24 and 25* ada ted to close the

channels

27 and 31, provi ed for the passage o'f the liquid und the exhausting nir respectively.

When the piston 24 is in its right hand position the li uid Hows from the channel 27 through a cumnel 27EL and pipe 28 in to the bottle'. The air expelled from the bottle vheilig filled flows' through a channel 2'9 to 'the channel 30 Vund thence to the chamber 100 4containing the piston 25. When the latter is moved to its right hand position the air flows through

channels

31, 32, 23, 22 and 33 to the ,vessel|4.

Above th-e movable filler head 1.5* is a 105 4l'zhli'n'r'lel 36 communicating with the atmosphere. When thebottle 1s under pressure, displacement of the 4filler head closes this channel. VVheu the pressure is relaxedthe said channel is opened by return of the 110 pressure fluid exhausts through said chan- .I so

one of the channels 12 inthe shell, and pipe 13 (left-hand side of Fig.v 1) to the cylinder 31. Rotation of the frame subsequently enables the pressure fluid to flow through ipe 13 .on the right-hand side to channels 12 and 14 (Fig. 2) and thence through

channels

15, 16 and 34 into the atmosphere.

Each of the sixteen fillers llls one bottle during each revolution of the frame, the operation of the apparatus being as follows; During rotation of t-he shell with the frame, the channel or groove 8 is in communication with a plurality of channels 12. Air flowing from the air-pump through 9, 11 and 8 flows through 12 and 13 to the cylinder 31,. successively lifts the bottle-holders `29 and bottles 28 by means of the pistons and piston-rods 30, and pressesl the bottles against the filler-heads. A channel 17 (Fig. 5) of. the shell 2 is then placed incommunication with channels' 21 and 10. Pressure fluid can then flow from the vessel.4 through 10, 21 and 17 to the bottle to be filled, and acts on the latteras previously explained. The latter are opened, and while liquid -flows into the bott-le through 24, 25, 26, 27 and 28, air flows from the bottle as .previously explained. Meanwhile communication between the-respective Achannels 17 and 21 (Fig. 5) has been broken, .so that the Aflow of pressure fluidjto the bottle being filled is cut 0H. The

bottle is filled, and the channel 1-7 isplaeed in communication with a channel 20 vof the plug 2, through which the pressure fluid the channel 17 and channels communicating therewlth canflow to channel 19, groove 18, pipe 35 and the atmosphere.- The valves I1n the box` 6 are then closed by the spring 23.- Continued. rotation of the shell brings l the filler shown on the left-hand side. of Fig.

1 to )the right hand position.. The pipe 13Y and ,channel 12' are placed in communication withth'e channel 14 in the plug, and the pressure fluid in cylinder 131 can ow through channels 15, 16 and pipe 34 to the atmosphere, so that the'` pistoncarrying the lilldbottle descends.

The air compressed by the pump is at considerably higher pressure than the pressure fluid in the vessel 4. The former has to' overcome the pressure of the latter, in addition to the weight of the-bottleand bottleholder.

In tlns modification also the .most essential feature is the control of the bottle-lifting fluid by means of the cent-ral cock which also controls the Y liquid for filling the bottles, and-the pressure fluid required for filling. The modifications shown do not exhaust the possibilities of the invention. Other means may be used for controlling all the parts by means of a central cock.

From the foregoing description it will be Y understood that the pressure fluid,'whicl1 may be Water or compressed air, acts on a piston in a cylinder located below the re- During each revolution of sure fluid to the pistonis `first opened, so that the fluid lifts the receptacleV and presses 1t against the filler-head. Then the said channel is closed, and finally, immediately after the closing, andduring the same revolution, the channel between the piston and central cock is placed in communication with an open channel of the cock, or with the pressure fluid reservoir, so that the fluid below the piston flows out of the cylinder and allows the filled receptacle to descend. Only a single device, the piston below the holder, is therefore required for pressing the recep- -tacle against the filler-head, inasmuch as the central cock, which may serve an indefinite number ofreceptacles, also controls Athe suply of pressure fluid to the lifting device.

y centralizing the control in this manner the workingof the apparatus is rendered very exact.
