To all whom it may concern.'

Be it known'that I, SAMUEL M. Humaines, a citizen of' the United States, residing in Haddontield, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Filling Machines, whereof the following is a speciication, reference being had to the accompanying drawings.

My invention relates to iilling` machines and apparatus for charging bottles or other containers,'my aim bein to secure rapid, accurate and economica operation, large capacity, simplicity and ruggedness of construction, durability and freedom lfrom derangement. 'The invention is of special advantage for the bottling of fluent materials or liquids such as milk, and l have herelnafter described and illustrated in detail the best embodment of the invention at present known to me with special reference to this application. How the above and o ther advantages can be secured in connection with the invention will appear from the description of the embodiment in uestion.

Fig. XI, is a fragmentary sectional view of one of the measuring vessels with a liner inserted to reduce its capacity.

Referring, first, to Figs. l, Il, and III, it will be seen that provision is made for feeding bottles through the machine in progressive succession, by means of a circular rotary table 2 mounted to revolve about a hollow post or standard 3 on the mainframe 4. The bottles handled by the rotary table4 2 are conveyed thereto and therefrom by means of

conveyor belts

5 and 6, shown as arranged in parallelism, and are guided by fixed lateral guards 7 suitably mounted on the supports 8 underlying the belts. To facilitate lling ofthe bottles as presently hereinafter described, provision is made for allocating them to definite positions or stations on the table 2 and maintaining them there, as by engagement means comprisin a double annular rack 9, of channel-shape cross-section, whose dange members have a number of peripheral semi-circular` or U- shaped notches 10 closely conformin to the forms of the bottles to be handle lt is preferable not to trust solely to the curved ends of the guides 7 and the pressure of that behind it for edecting transfer of each bottle between the table 2 and the

conveyors

5 and 6; and l have, therefore, provided for this purpose additional means in the form of double rotary star-wheels 11 and 12 operating in step or in phase with the movement of the stations on the table 2. The star-wheel 11 tolls the bottles 1 ed to the stations in a deiinite and positive manner as said stations come into correspondence with the conve or 5, and the star-wheel 12 performs a slmilar function in reference to the conveyor 6 and the discharge of the bottles from the table. Trouble from jammin of the bottles at the star-wheels may be o viated by lexible or yielding construction o the free inner guide ends 13 and 14, which extend between the star-wheel disks and between the flanges of the bottlev rack 9. As shown, the end section 13 of the guide for the approaching bottles is made as a separate piece, pivoted at 15 and yieldingly held in position by a leaf-spring 16 attached to the adjacent fixed guide member 7. The curved end 17 of the outer guide 7 insures proper pocketing of the bottles 1 in the rack 9 when lilling begins, as described hereinafter. When it is desired to\stop the progress of bottles to the table 2, a` stop or gate sustain the bottles as they are transferred between the belts and the table.

` To sec-ure the most rapid and economicall operation, the filling o f each bottle 1 should begin as soon as practicable after the bottle reaches its station on the filling table 2, and

the fioat-valve 27 ma ress of the bottles,-accordin to the preferred mode of operation out med above,-

be set to maintain the reservoir supply leve below the bottom wall or ioor of the tank overhang 22, -provision being vmade for periodically delivering the milk to replenish the vessels 30 as required. Elevation and delivery of the milk to the overhang 22 and the vessels 30 may be accomplished by means of a rotary bucket lifter`3l (see also Fig. IV), that dips into the milk to fill its buckets. This bucket should end 'ust before it is removed frorn\ Wheel 31 is carried by an inclined revolving the table.- his involves troducing the desired fi ling1 or char e (whethersuch as to fill the bott e complete y or not) in correspondence 'with the normal advance of the bottle through the machine. .In order, however, to insure against over-l .filling or wastage, etc., in case the progress of the bottles should be delayed by any occurrence out of the normal (such as a failure or slowing down of the machine drive, for example), I prefer not to rely solely on coincidence of the filling time with the time it takes for a bottle to complete its progress through the machine, but to provide for measuring or premeasuring the filling charge independently of such abnormally delayed progress. I prefer, also, to employ filling means moving with each bottle in its travel through the machine- Still referring to Figs. I, II, and III, it`

will be seen that on the illing table 2 there is a tank structure 20 which comprises a main lower annular reservoir portion 21 surrounding the hollow axial standard 3, and carrying the bottle rack 9 on its outer Wt'all, and an enlarged outwardly projecting upper portion or extension 22 overhanging the bottle stations on the outer edge of the table. The reservoir 21 contains a convenient Working supply of milk, which is delivered thereto by a supply pipe 23 eX- tending through the tank cover 24, which is mounted on la ring 25 supported from the machine frame 4 by bracket standards 26. A constant level of the working supply in the reservoir 21 is maintained by a floatvalve 27 controlling the discharge from the supply pipe 23. The Whole tank structure 2O revolves, of course. with the table 2.

The bottle-filling means moving with the bottles 1 is associated with the tank overhang 22, and comprises a plurality of externally shouldered conical-bottomed vessels 30 each set into the floor of the overhang directly over a bottle station with their open tops or mouths exposed through or above the overhang floor, so as to serve as outlets for delivering milkfrom said overhanging tank extension 22 to the bottles 1 at the stations 9 therebeneath. With a view to the measuring o of the bottle charges independently of abnormally delayed progrogressively inshaft 32 mounted in bracket bearings 33 at the top of the standard 3, so as to revolve in a xed position about an inclined axis. The scoop buckets 34 fill while immersed, move in step or in phase with the movement of the vessels 30 as they rise above the overhang vfloor and the vessels 30, and begin to spill freely about as they come over the latter, so as to discharge their contents into the respective vessels that are moving in coincidence and in approximate parallelism with them while they are in the upper part of their owm ath.

In genera I prefer not to rely on exact admeasurement or premeasuring of the bottle charge by the delivery from theV buckets 34 to the vessels 30, but to make the bucket capacity somewhat excessive and to make the vessels 30 of capacity just equal to the desired charge,-as a pint, a quart, etc.,`so as to serve as accurate premeasures. This not only tends to insure full charges and greater accuracy and economy, but-facilitates variation of the charges by changing the vessels and altering the speed adjustment'of the machine. lThe surplus milk overflows the upstanding open ends of the vessels 30 and drains back into the reservoir 21 over the apron formed about the bucket mouths by the inclined ioor of the overhang 22. Thus the overhanging Hoor or apron serves as a means of returning all excess milk to the reservoir 21 quickly and without danger of spilling.

The vessels 30 deliver into the bottles 1 beneath them through outlets in the form of discharge nipples 35 Which are controlled by -conical-ended valve members 36 (see Figs. I and V) hung on link-rods 37 which freely permit 4self-centering of the valves in the nipple seats. Swirling of the discharging milk and consequent entrainment of air therewith are prevented by means of vanes or fins 38 adjacent the outlet openings, projecting radially from the valve members 36. (See Figs. V and VI.) Each valve linkage 37 is connected to a control mechanism which is mounted on a bracket piece 39 attached to an angle iron 40 with which the upper edge of the tank structure 20 is reinforced. This control mechanism includes (see Fi I, II, V, VII andVIII) an externally shouldered I ,leasoi sleeve member 41 seated in a hole in the bracket 39 (lar e enou h to permit the valve 36 to be passedgthroug it), and adjustably secured by a set-screw 42; a member 43, turnnble in the sleeve 41, to which the linkage 37 is directly attached; and an olperatin mechanism for the member 43 whic I sha1 resently describe. The sleeve member 41 as in its upper end notches or recesses 44 with rather steeply inclined cam-faces 45; and the member 43 has at its upper end projections 46 with inclined cam-faces 47 corresponding to the cam-faces 45, and co-operatin with them, when the member 43 is turne one way or the other, to raise or lower the member 43 and thus open or close the filling valve 36,-the parts 41 and 43 thus constituting a vertically-actingy crown cam mechanism for operating the valve 36. When the member 43 1s once ully raised, its projections 46 Tide on the upper end of the sleeve. 41, and the valve 36 1s thus securely and positively held or locked open.

'lhe operating mechanism for the member 43 comprises a slotted crank-arm 49 secured on its upper end and an actuating lever or control member 50 fulcrumed on a stud 51 on the bracket piece 39 and having at one end an upstanding pin 52 which engages in the slot of the crank-arm 49. Rocking of the control lever 50 to a suitable extent will, therefore, either close the valve, or open it and secure it open,according to whether the outer end of said lever 50 is shifted in the direction of the clockwise rotation of the table 2 (Fig. H), or in the reverse direction. When the arm 49 is shifted horizontally one way or the other, it also moves up or down, as the case may be.

llt is, of course, preferable that the milk valves 36 be opened and closed automatically, and that they be not opened at all unless bottles 1 are actually beneath them. As shown in Fig. Il, there is mounted adjacent the path of movement ofl the control operating mechanism and the members 50 an actuating member or device 55 in the form of a claw or dog fulcrumed about a ost 56, supporting a stationary bracket 57.

he outer ends of the control lever 50 have notches with inclined faces 58 adapted to engage securely with the hook or` claw tooth of the dog 55 when the latter is in proper position, as indicated in dotted lines in Fig. Il. Just above the bracket 57 is one arm of a bell-crank lever 60 whose shaft extends down through said bracket to the other arm 61. The arm 60 has a pin and slot connection 62 with the rear end of the dog 55, while the arm 61 normally extends into the path of the bottles at such a point as always to be actuated by wiping contact with the bottle whose control lever 50 must next pass or encounter the dog 55. By these means, therefore, the presence of a bottle 1 to be filled controls and brings about the shifting of the dog 55 into engaging position and the actuation of the correspondin control member 50 to .open the valve 36 an supply milk to the bottle. As the claw tooth of the do 55 is moving each control member 50, it ri es against the inclined outer end 63 of the associated bracket piece 39 and is thereby thrown out of engagement after fully opening and securin the valve. By this means, the actuating og member 55 is automatically retracted into inactive position after each actuation of a control member thereby; so that if there be no bottle at the next station, the corresponding filling` means will not be brought into action.

The curved free end 17 of the outer guide 7 serves to restore the bottles to their proper seating in the station rack 9 if they should be slightly displaced by the wiping crankarm 61.

As shown in Fig. Il, closin of the valves 36 is brought about just be orethe corresponding bottles reach the tabledischargng or unloading star-wheel 12, by engagement of a stationary stop arm 65, supported from the machine frame 4 adjacent the path of movement of the control operating mechanism, with the actuating 4crank arm 49 itself. When the crank arm 49 is thus turned Sulliciently to let the inclined cam faces 47 of the projections 46 of the member 43 come upon the stationary inclined cam faces 45, the crank arm 49 descends out of engagement with the stop arm 65,--gravity aiding this descent and finally carrying the arm 49 down an amply suiiicient distance. rlhis not only closes the valves 36 preparatory to refilling of the vessels 30, but also restores the control member 50 to position to be again actuated by the dog member 55.

Thus the replenishment of the vessels 30 is effected by means quite independent of that by which the bottles 1 are filled from said vessels,-although, of course, both of these operations are dependent on the continued operation of the machine by the drive shaft 81. Such independence allows the vessels to be always .replenished and ready to till bottles at each revolution of the table 2, whenever bottles are present at the filling stations, while, at the same time, it allows the actual deliver vof filling to the bottles to be made depen ent on their resence.

As shown in Figs. IX and the ordinary milk bottle has in its mouth a shoulder which serves as a seat for the usual paper p disk cap or stopper closure. lt is undesirable that the milk in the bottle should stand above this seat 70, since such a condition leads to sloppy and unsi htly capping. Commercial milk bottles, owever, vary somewhat in ca acity, so that to insure against bad resu ts in capping it is necessary -to bring the milk level to a definite ment with the bottle mouths, -downward,

movement being limited by a stop 770 on the bracket. One end of this tube 74 extends thereinto, while its other end constitutes a substantially vertically moving suction noz-v -zle with curved or arc-shaped gauge-fins 77 adapted to control the action of the nozzle through engagement with the bottle-mouth, so as to remove any excess of milk. The gauged nozzle`77 overlies the path of the bottles 1, in position to engage and wlpe over them as they pass it under the impulsion of the star-wheel 12. A suction or aspirating action is produced on the injectorprinciple, by a blast of air from a nozzle 78 connected by a tube 79 to any suitable source of air Pressure. p

Referring, now, to Figs., I, II, and III, once more, it will be seen thatpower to operate the machine is received by a pulley 80 on a main shaft 81 journalled in bearings on the main frame J4. The table 2 is rotated by means of a large gear 82 secured beneath it and meshing with a inion 83 at the u from the shaft 81 through worm gearing 85. The donveyor belt 5 is driven by a roll 86 which, in turn, is driven through a sprocket chain drive 87. from a short horizontal shaft 88 itself driven from the shaft 81 through bevel gearing 89, see Figs. I and III. The drive of the conveyor belt 6 does not appear on the drawing and requires no description, since this belt 6 need not (like the belt 5) operate with any particular speed relation to the bottle handling parts of the machine proper,all that is required of it being to carry away the filled bottles 1 from the machine. The star-wheels 11 and 12 are belted together by a chain drive 90, and the upright shaft 91 of the wheel 11 is driven directly ,from the shaft 81 through bevel gearing 92.

The inclined shaft 32 of the elevator bucket wheel 31 is driven through bevel gearing 93 from a vertical shaft 94 that exten s up through the center of the standard- 3, and is itself driven from the shaft 81 through worm gearing 95. A gutter 96 beneath the edge of the table 2 serves to carry olf any dri pings of spilt milk.

gince in the machineA shown the table 2 l has thirty-six bottle stations and the wheel 31 has nine buckets, the wheel 31 should per end of a vertical sha t 84 driven make three revolutions for each'revolution of the table. For filling quart bottles, the latter may run as fast as two revolutions a minute, `iving an output of seventy-two bottles fil ed every minute.

For pint bottles, the capacity of the vessels 30 may be diminished to pint size by insertion of liners 100, as indicated in Fi XI, to serve as displacement means for this purpose.

It will be seen that in the operation of the machine, the su ply of milk to the series of revolving vesse s 30 is effected within their orbit and that of the bottles 11, which are carried around with them in their movement, and the return of milk to the supply in the reservoir 21 likewise takes place within the orbit of vessels and bottles. Under all conditions Aof capacity variation `of the vessels 30, definitely excessive amounts of milk may be delivered to the successive vessels, so as to assure complete filling and overflow in every instance.
