Patented May 29, 1951 UNITED STT-ES PATENT Y OFFICE AALIQUU) FILLEB/ n Frank- D. Chapmamlerlin, Y Application Alprilr, 19465,` Serial No. 65?.:30? n This invention relatesin general to improvements in commodity measuring and dispensing devices, and relates morespecically to improvements in machines for automatically pre-measuring and' for delivering measured batches -of liquid to a succession of receptacles travelling along a denite path.

The primary object off'my invention is topro--v vide an improved receptacle Vlling machine which is operable at any ldesired speed to-deliver accurately pre-measuredbatches of fluent commodity such as liquid to a travelling series of cups or cans without waste. l

Many different types of receptacle orfcanfll-y ing machines for delivering pre-,measured batches of diverse commodities to successive cup-shaped containers advancing along `deiinite paths, have heretofore been proposed and used commercially; andlwhile some ofthese. previous fillers arequite satisfactory so far as Iaccuracyoi performance is concerned, mostof them are relatively complicated and operableA onlyvat rather slow speed especially when handlingl'liquids. In the most reliable and accurateliquid ,fillers now in ruse, the receptacles are causedto .traverse annular or irregular paths while receivingthe pre-measured batches of commodity fand thereafter untilthey are delivered. from the Imachine, and When the. liquid laden containers are thus revolved about an axis or irregularly advanced beyond a denite speed, some of the productspills over the brim of each receptacle and considerable waste results especially when the batches are of considerable volume. Then too,. it. wasimpossible with these prior fillers, to accurately adjust theA deliveries so as to properlyv cooperate with straight line high speed can conveyors. j

It is therefore a more specific object of the present invention to provide an improvedliquid ller adapted to operate at `high, speedrwithout zoclaims. (c1. 22e-104) `1 l shaped lreceptacles such as open-topped cans, and-Which fpositively'favoids delivery of batches when-there` are no cans in position to receive the same' .,r-V -;VY Y

A Still another specific object of my invention is -to providev an vimproved can lling assemblage all parts tof-which are readily accessible for inspection andmay beV dismantled for cleaning, which may, f-be n conveniently assembled, and wherein Vthe accurate'.premeasurement of the batches or: charges may be safely. effected while themachineis inxoperation.KV v l. An additionalspecific objectiof this invention is to'provide animproved liquid batch measuring and delivering unit adapted Kto be readily applied tofand operatedin conjunction with machines for automatically lling. cans or other receptacles with mixturespffliquids and Asolids-wherein the ingredients- .mustf be accurately proportioned.

While the invention has been shown rather diagrammatically as being advantageously applicable to an automatic liquid ller for a succession of open-topped sanitary cans, it is not my desire or intent to unnecessarily restrict the utility of the device by virtue of this specific and limited embodiment, and itis definitely contemplated to apply the improved liquid batch measuring and dispensing unit to machines for delivering mixed liquid and other materials in the form of successive charges to diverse receptacles and other zones of utilization.

Referring to the drawings, the typical liquid ller shown therein, comprises in general a liquid supply basin or tank 1 mounted upon normally fixed frames 8 which are adjustable along a supporting base 9 by means of positioning and clamping screws I; a rotor II having therein an annular series of radial spaces or measuring pockets I2 revolvable within the tank 1, and being provided with a supporting and propelling spider and hub assemblage I4 keyed to a lower driving shaft I5 which is journalled in end bearings I6, I1 xedly associated with the opposite end walls of the tank 1; a stationary arcuate or segmental ange I8 extending centrally within the rotor II coaxial with the shaft I5 from the tank end wall I9 which is provided with an upper outlet opening 20, the flange I8 sealing the inner ends of a limited number of the pockets I2; a normally fixed annular closure or ring 22 embracing the rotor II so as to seal the outer ends of all of the pockets I2 except for a spill slot or liquid return opening 23, the ring 22 having an annular series of peripheral teeth 24 and being journalled for rotary adjustment about the shaft I5 within a circular groove 25 and also being held in place by local clips 26; a ring adjusting pinion 21 meshing with the teeth 24 andbeing secured to an auxiliary shaft 28 mounted in bearings on the tank wall I9 and in a bracket 30 located within the tank 1, the shaft 28 being adjustably rotatable with the aid of a crank 3|; an annular series of radially disposed revolving funnels 32 mounted upon an upper power shaft 33 byY means of a spider and hub 34, and being communicable over a spout 35 secured to the wall I9 with the liquid batch discharge opening 28; la ap valve 36 pivotally suspended from the tank wall I9 and normally sealing the opening 20 but being periodi` cally movable to uncover the liquid discharge opening so as to deliver measured batches of material into the successive funnels 32; and mechanism for driving the shafts I5, 33 and for periodically opening the valve 36.

The tank 1 should be of ample capacity to meet requirements and may be kept supplied with liquid 38 such as brine or syrup, from any suitable source and in any vconvenient manner, and the major portion of this tank may be formed of sheet metal while the upright end wall I9 should be formed rigid and of durable suitable material, see Figs. 1 and 3. A conventional straight-line receptacle conveyor 39 is preferably supported adjacent to the tank wall I9 beneath the path .of revolution of the funnels 32, and this conveyor 39 is adapted to travel horizontally and at high speed upon a carrier plate 40 mounted upon brackets 4I, see Figs. 1 and 5. The conveyor 39 is provided with propelling lugs or projections 42 which are spaced apart uniform distances equal to the distances between the discharge ends of the successive funnels 32, and which are adapted standard straight line conveyor 39, the two sections of the base 9 are also provided with jack screws I0 as shown.

Thevconveyor 39 may be operated in any suitable manner to constantly advance the cans 43 atany desired speed, and the funnels 32 and rotor II should be timed to operate or revolve at corresponding speeds. rLhe upper driving shaft 33 which carries the funnels 32 is journalled for rotation in bearings 46, 41 associated with the end walls of the tank 1, and this shaft 33 may be driven at the proper speed by means of a chain drive 48 or the like associated with the end ofthe shaft remote from the funnels 32. Rotary motion is transmitted from the upper power shaft 33 to the lower rotor driving shaft I5 by means of gears 58, 5I keyed to these shafts respectively, in order to simultaneously revolve the rotor II and the funnels 32 in the directions indicated by the arrows during normal operation of the machine, see Figs. 3, 4 and 5. The auxiliary shaft 28 should be rotatable for purposes of adjusting the ring 22 only, and should not be affected by the continued rotation of the shafts 33, I5; and when the shaft 28 is rotated with the aid of the crank 3| and pinion 21, the spill opening 23 may be raised or lowered to vary the quantity of liquid 38 confined in each pocket I2 when it reaches the nal discharge opening 20.

While the ap valve A36 for periodically opening and sealing the liquid batch discharge opening 20 in the tank wall I9 may not be necessary in cases where it is desired to have the funnels 32 deliver successive measured charges of liquid without interruption; it is preferable to provide such a shut-off valve 36 when delivering measured batches of liquid 38 to a succession of receptacles or cans 43, in order to prevent waste oficommodity in the event that no receptacle is in position to receive a liquid charge. A simple but highly effective no-can no-ll mechanism for controlling the flap valve 36 is shown in Figs. l, 2 and 5, and comprises an upright slide 52 guided for vertical reciprocation by lower and upper guideways 53, 54 respectively, carried by the rigid tank wall I9; an elongated can engaging or contact bar 55 carried by one arm of a bell crank lever `56 which ispivotally suspended from the wall I9 and the other arm of which coacts with a pair of lugs 51 secured to the medial portion of the slide 52; a pair of toggle links 59, 60 pivotally connected by a pin 6I and swingably attached respectively by means of other pins, to the valve 36 and to a bracket 62 carried by the fixed wall I9, the central toggle pin 6I being connected to the upper.- end of the slide 52 by means of an adjustable link 64; and a tension spring 63 coacting with thelower extremity of the slide 52 andV tending-,to constantly pull the slide downwardly and to thereby close the flap valve 36. While the valve 36, toggle links 59, 68, bracket 62, and link64 are disposed within and normally concealed by the annular funnel rotor, this rotor is provided with a central outer opening 65 through which the link 64 is accessiblehfor the purpose of varying its length so as to insure prop--l er closing of the valve 36 and proper disposition of the can contacting bar 55.

During normal operation of the improved liquid ller, after the various parts have been properly constructed and assembled, suitable adjustments of the tank 1, rotor II, and funnels 32 relative to the conveyor 39 with the aid of the adjusting screws l0, I and base 9, and proper adjustment of the length of the link 64 in order to insure closing of the valve- 36 and correct disposition of the actuating'bar 55, should rst be made before the machine is 'set in motion. The supply tank 'I should also be provided with an abundance of the liquid 38 whereupon power may be applied to the sprocket 48 and to the conveyor 39, and successive cans 43 should be applied to the transporting lugs 42 of the conveyor; thus causing the measuring rotor II to revolve about the flange I8 and within the volume varying ring 22, and also causing the annular series of funnels32 to simultaneously revolve in timed relation to the advancing cans 43 As the measuring rotor II revolves and the lower open pockets I2 thereof become immersed within the liquid bath, the successive revolving pockets become completely filled with liquid 38 as illustrated in Figs. 1 and 2. The successive liquid filled pockets are sealed by the flangev I3 as they rise from within the supply basin, and when they reach the spill opening 23 of the sealing ring,22, a definite amount of liquid 38 is returned from each pocket I2 through the opening 23 to the tank 1. Successive equal batches of liquid 38 are thus accurately measured, and the pre-measured batches are subsequently carried into open communication with the upper batch discharge opening 20. If the valve 36 is opened when the measured batches reach the opening 20, the successive charges will be discharged into the successive revolving funnels 32; but if the valve 36 remains closed, the premeasured batches will remain confined within" the pockets I2 until they are returned to the supply liquid 33 within the tank 1.

The actual volumes of the vsuccessive measured batches depends upon the elevation of the spill opening 23, and as this opening is lowered by rotary adjustment of the sealing ring 22, the volume of each charge lwill diminish. This action is clearly exemplified in Figs. 3 and/fl, from which it will be apparent that lowering the opening 23 will reduce the batch volume, whereas raising this opening 23 `will increase the volume of eachk batch. Such variation may be readily effected while the machine is operating, by merely revolving the ring 22 with the aid of the pinion 21 and hand crank 3l, and when the desired adjustment has been effected each of the successive batches will have exactly the same volume.

When successive receptaclessuch as tin cans 43 are being supplied with batches of liquid 38, the successive cans are caused to gradually engage the valve of actuating bar 55, and as each can 43 advances along this swingable bar, it causes the bell-crank 56 to lift the slide 52 in opposition to the action of the tension spring 63. Each of these upward movements of 'the' bar 52 causes the toggle links 59, 60 to be pulled out of alinement or at an angle to eachother as clearly shown in Fig. 2, thus opening the valve 36 and permitting the'adjac'ent measured' batch of liquid 38 to escape from its conning' 755 construction, nor to thevprecisemode of use,`

pocket I2 through the opening 20 and through' the adjacent funnel 32 to the can 43 disposed beneath the funnel outlet. However, if the can series is interrupted for any reason, and no can f 43 is brought in` contactwith the valve actuating bar 55, then the valve 36 will remain sealed, and no discharge of liquid will take place. In this manner, waste of material due to the absence of a can 43, is positively prevented, and since the cans 43 are constantly travelling in a straight line and their motion is not interrupted during delivery of a batch thereto, no spillage of liquid over the upper brims of the cans will occur. After each delivery of a batch to a can 43, the spring 63 quickly becomes effective to restore the bar to the position shown in Fig. l, and to simultaneously close the valve 36.

From the foregoing detailed description it will be apparent that my present invention provides an extremely simple, compact and durable liquid batch dispensing unit, which may be operated at high speeds to deliver accurately pre-measured batches of liquid to a succession of containers 4or zones of utilization. The improved batch measuring rotor II and the sealing ring 22 cooperating therewith, may be quickly and effectively adjusted to accurately vary the volumes of the successive batches measured, and such adjustment may be readily effected while the machine is operating at high speed. The simplified no-can no-ll mechanism eliminates possible waste of liquid due to the interruption ofl the can series, and the liquid which is spilled fromleach pocket l2 during measuring of the charges, is returned directly to the tank thus positively eliminating waste of material. By virtue of the fact that the cans 43 constantly travel in a straight line and do not have their motion arrested when the liquid is being deposited therein, this improved filler may be operated at considerably higher speeds than was possible with prior liquid measuring and dispensing machines,

and while the various parts of the mechanism are amply protected during normal operation, they are still readily accessible for adjustment, inspection, and cleaning. The. provision of means for causing the improved iiller to ac-v curately cooperate with standard straight-line' high speed can conveyors 39, and to also co-g operate with cans 43 of different heights and diameters, is an important feature of my present invention, and such adjustments may be quickly and effectively accomplished by merely manipulating the screws I0, I0 and without Vin any manner disturbing the can conveyor 39.`

The adjusting screws I0 servey to bodily shift the funnel series along the conveyor 39 so as to linsure proper cooperation of the funnel outlets with cans 43 of different diameters, whileythe `jack screws I0' serve to bodily shift the funnel series toward oraway from the conveyor so as` to likewise insure proper cooperation of the funnels 32 with cans of dierent heights,

thus adapting the filler for cooperation with re;

ceptacles of various sizes. The improved liquid iiller'may obviously be manufactured at moderate cost, and occupies very little space considering its capacity, and the liquid filling unit is well adapted to be associated with machines 'for' measuring and delivering successive charges each comprising a mixture of liquid and other materials. y
