This invention relates to filling apparatus with particular reference to liquids to be transferred to bottles, jars and other vessels.

In apparatus of this type, the liquid controlling valves are operated by a transmission mechanism producing an intermittent motion whereby the valves are alternately caused to open and close to allow for-time consumed in changing from filled to the next succeeding empty vessels.

The transmission mechanism preferably includes change speed gearing in continuous motion, whereby the length of the filling periods can be varied without materially affecting the time allowed for changing the vessels between the filling periods.

One of the objects is to provide apparatus for filling with regulated quantities. 7

Another object is inthe provision of an apparatus capable of filling a plurality of vessels simultaneously.

A further aim is to provide means whereby each nozzle intermittently partially fills the Y vessels, so that the same may be conveyed at a steady rate.

A still further characteristic is in the provision of means for applying heat, thus enabling the steady flow of thick or dense liquids.

These and other objects,'which will become apparent as the description progresses, are accomplished by the novel construction, combination and arrangement of parts, hereinafter described and illustrated in the accompanying drawings, forming an important component of this disclosure, and in Which Figure l is a partial side elevational, partial transverse sectional view taken on line 1-1 of Figure 2.

Figure 2 is a front elevational view of an embodiment of the invention, as disclosed herein.

In the drawing, the numeral 5 generally designates a rectangular base having bearings 6 spaced along the front edge thereof, in which is journalled a shaft 7.

Mounted on the shaft intermediate the bearings is a pair of spaced sprockets 8 connected by chains 9 with similar sprockets 1O '50 fixed on a sleeve ll'rotatable on a shaft 12 1927. Serial No. 172,959.

journalled in bearings 13 rising from the base 5.

Loose on the shaft 12 is a pair of sprocket wheels 14 connected by chains 15 with larger sprockets 16 fixed on a shaft 17 j ournalled in the lower bearings 18 of a support 19 suspended from the ceiling.

Looselymounted on the shaft 17 is a gear 20 and a pinion 21 meshing respectively with a pinion 22 and a gear'23 fixed on a shaft 24 journalled in the upper bearing 25 of the supports 19, the shaft 24 being positively driven by a mechanism (not shown) in a continuous motion.

Keyed on the shaft 17 and slidable thereon intermediate thegear 20 and pinion 21 is a disc 26 provided With a groove 27 in its peripheral surface, the groove being engageable with a pin 28 fixed in a lever 29 pivoted at 30.

'The disc26 is also provided with pins 31 on both sides selectively engageable with pins 32 and 33 respectively fixed on the adjacent surfaces of the gear 20 and pinion 21.

-Thus, by moving the lever 29 so that the pins 31 engage the pins 33, the gear 23 driving the pinion 21,-will' through the disc 26, drive the shaft 17 at high speed.

Also,'by moving the lever 29 so that the pins 31, engage the pins 32, the pinion 22 driving the gear 20, will, through the disc 26, drive the shaft 17 at low speed. s 7

Fixed on the shaft 17 intermediate the sprockets 16, are similar sprocketwheels 34 connected by chains 35 to like wheels 36 loosely mounted on the sleeve 11, the chains carrying at regular spaced intervals between them, a plurality of bars 37 adapted to engage lugs 38 formed 'on the sleeve intermediate the wheels 36.

Formed on the base 5 in the rear of the bearings 6, are corresponding bearings 38 in which is journalled a shaft 39.

Fixed on the shafts 7 and 39- are rolls 40 over which'is trained an endless conveyor belt 41, the same being further supported by a plurality, of rollers 42 journalled in side supports43, so that the weight of the containers- 44 carrying the receptacles 45 to be filled,

will be firmly sustained. v

Slidably keyed on the shaft 12 intermediate the bearings 13 and wheels 14, are discs 46 provided with grooves 4'? and pins 48 engage able with pins 49 on the outer faces of the wheels 14; the grooves 47 engaging pins 50 fixed on levers 51 pivoted at 52 to a cross-support 53 between the vertical supports 54. i

The shaft 12 extends outwardly, entering a casing 55 inwhich are t'anks 56, and below them are a pair of square chambers 57 at right angles each having a cylindrical'nozzle 58 extending downwardly 'from its inner open end, the tanks 56 being connected at their lower portions by pipes 59 to the inner ends of the chambers 57. I 7

The upper wall of ea'chchamber is lined with a rubber packing 60 and slidable inthe chambers are pistons 61 connected by links-62 to flat rectangular slides 63 movable over guide plates-64011 the lower central wall of the casing 55 intermediate tile nozzles 58, the plates beingrecessed to receive rubberpackings 65 between them and the casing wall and the pistons'are also recessed to receive rubber packings 66. v

The plates 64 are formed on cam brackets in which are operable cams 68 fixed on the shaft 12.

Passing over the casing 55 are substantially W-shaped pipes69 through which steam-is forced to ;keep the substance contained inthe tanksbG from becoming thick or dense, and by so doing prevent clogging of the appaatu Thus in operation, motion is transmitted from the drive shaft 2-24 to the shaft at either high speed or low speed depending upon the engagement of the disc clutch 26.

Throughthe bars 37 ofthefchain 35, lugs 38, wheels lO 'and chains 9, the conveyor belt 41 is actuated intermittently, although the machine drive is continuous. 7

Simultaneously, the shaft 12 is rotated,

through the chains 15, wheels l-4 and the discs 46 which action,throug-h the cams 68, actuates the pistons 61 so that when a container 45 is under the nozzle58 the piston61 moves toward that nozzle to force the liquid, from the tank56 to thechamber 57, into the container;and as the piston moves forward it closes thepipe 59 stopping the flowof-liquid. By this time the container 45 is filled and the conveyor moves it on-so that when the piston starts again, the next container 45 will be in a position beneath the nozzle.

Thus by thereciprocating motion of the pistons and the conveyor the containers are alternately filled and then carried away.

it may be seen that the quantity of the liquid allowed to flow may be regulated by the speed of the cams --68 and these in turn controlled bythe lever 29, V

Although the foregoing is descriptive of the preferred--embodiment of the invention, it will be apparent that-minor changes may be made in-its construction, without I the exopposed apportioning chambers therebelow,

valves movable in said chambers, looped brackets connecting said valves in paired relati'on,1a shaftrevoluble in said tank, cams on said shaft engaged in said brackets to reciprocate said-valves, and tubular connections between said chambers and tank controlled by said valves.

'2. An apparatus for supplying containers withliquid comprising a tank, a series of opposed apportioning chambers there'below, said chambers being rectangular in cross section, Valves connected in paired relation operative in said chambers, packings in the upper portions of said chambers to contact the upper surfaces of said valves, other packings carried in the lower surfaces of said valves to contact the lower portions of said chambers, a constantly rotating shaft passing longitudinally through said tank and cams :fixed on said shaft to cause said valves to move reciprocatively at regular intermittencies.

In testimony whereof I have signed my name to this specification.
