Fig. 15 is a plan view of the stock feeder shown in Fig. 14, certain parts being broken away to illustrate the construction more clearly.

As stated above, the instant invention is concerned with a machine for preparing and placing in a container a mixed charge in measured amounts of a plurality of stocks, some of which because of their expensive nature or the character of ingredient are selected to form a small part of the contents of the containers, and others of which because of their inexpensive nature or because they are desired in larger quantities are selected to form the bulk of the contents of the containers. Such invention will be described as it is embodied in a machine which is adapted especially for preparing a fruit cocktail in which ingredients such as marasehino cherries, grapes and pineapples are employed as the individual stocks and in which ingredients such as diced pears and peaches are employed as the bulk stock.

Generally, the machine comprises a filling unit having an endless series of receptacles, preferably in the form of pockets, with which are associated a plurality of individual stock feeders for dispensing measured amounts of the stocks contained therein into each receptacle, together with a stock mixer and feeder which receives bulk stock from an elevator unit and fills the receptacles from the stock contained therein.

All of the stock feeders are driven in synchronism with the series of receptacles, which also has synchronously related therewith during one part of its travel, an endless chain of containers, sucn as cans or the like, into which the receptacles are emptied during their travel and thereby made ready for subsequent refilling. All of the parts of the machine are adjustable to accommodate various size containers, as well as to vary the proportion of any stock in the charge for a container. I

The filling unit of the machine includes a frame for supporting the various parts of the machine, certain of which are supported adjustably to provide for accommodation of various sizes of containers, such as cans or the like. The frame includes base plate I (Fig. 2), supported by a plurality of legs 2, and having similar sets of pads 3 and 4, (Figs. 2 and 5) formed thereon to support parts of the machine which are not bodily adjustable. To provide an adjustable support for other parts of the machine,

base plate I has a plurality of internally threaded bosses 6 spaced about its periphery in which threaded Standards or posts 1 have threaded engagement, being locked in assembled upright position on plate I by respective nuts 8. Posts 'I are connected at the top by a vertically adjustable spider assembly including annular center plate 9 (Figs. 1 and 2) and radially disposed arms IIl which may have their inner ends secured to plate 9 as by welding, and their outer ends apertured to engage over reduced threaded ends I I of respective posts l. A pair of nuts I2 on each post end II are associated with each arm I to secure the spider assembly in its vertically adjusted position on posts l.

Associated with the above described frame, is a central spindle or standard which provides an axis of rotation for certain parts of the machine as well as serving to maintain such parts in assembled position on the frame. Central spindle or standard I6 (Fig. 2) is journalled by suitable bushings in central boss I'I of base plate I and extends upwardly therefrom through hub I8 of drive gear I9, hub 20 of plate 2I which supports the bulk stock mixer and feeder as well as the charge receiving receptacles, and through hub 22 of elevator unit mounting bracket 23. Spindle I6 is keyed to hub 20 of plate 2I which is mounted for vertical adjustment by split threaded end 24 thereof which has threaded engagement with hub I 8 and is locked in adjusted position thereon by clamping bolt 25. Hub I8 is supported by boss I'I of base plate I, so that relative adjustment of hubs I8 and 20 also causes spindle I6 to move in boss Il. Hubs I8 and 20 and spindle I6 are held in assembled adjusted position on base plate I by split collar 25 adjustably clamped on spindle I6 adjacent the lower end thereof by bolt 21 and nut 28, and engaging boss Il to maintain the parts in the selected adjusted relation. Nut 28 has handle 29 to facilitate adjustment of collar 26 on spindle I5.

The various parts of the machine mounted cn the frame, including the driving means, the charge receiving receptacles, the bulk stock mixer and feeder, the bulk stock elevating unit, the individual stock feeders, and the container or can feeding means, will now be described in detail. All elements of these parts which can come in contact with the stock are made preferably of non-corrosive metal, such as stainless steel.

Driving means The driving means of the filling unit includes a source of power and a central driving clement which can be driven at selected speeds from the source of power and from which a plurality of individual drives are taken to various parts of the filling unit which are driven in synchronism with each other.

The source of power comprises electric motor 4I, (Figs. 2 and 5) which is secured to pad 42 on one of supporting legs 2 for lateral adjustment by means of suitable bolts engaging horizontal slots 43, (Fig. in pad 42. Only one of slots 43 is illustrated. Motor 4I is connected by suitable reducing gears and shear pin 44 (Fig. 5) .with driving pinion 46 removably mounted on drive shaft 41 of the motor. Pinion 46 meshes with drive gear I9, which as described above is mounted on spindle I6.

Gear I9 comprises the main driving element of the lling unit and can be driven at selected speeds from motor 4I by selecting pinions 46 of 75 and the like, to provide for uninterrupted operation of all such machines. Usually, the machine will be operated at a higher speed with the smaller sizes of containers. The drive connections from gear I9 are described in connection with particular parts of the machine which are driven thereby.

Bulk stock hopper and charge receiving receptacles I'he charge receiving and transferring means includes a series of receptacles which are moved successively past the discharge openings of the various individual stock feeders and thereafter through a discharge area in the bulk stock hopper or mixing bowl and into registry with the containers, which for a part of the travel of the receptacles move in synchronism therewith as described hereinafter. Preferably the receptacles are in the form of open ended telescopic cylinders carried by the bulk stock hopper and having a closure element associated with the lower ends thereof during the fillingl phase of their travel to form pockets.

lReferring to Fig. 2, the bulk stock hopper 60 includes base 2| which is adjustably mounted on drive gear I9 for rotation therewith, as described above. 'I'he hopper is formed on base 2| by bottom wall 6|, and inner' and outer cylin- .

drical walls

62, 63, respectively, which are secured to base 2|, preferably by welding. Bottom Wall 6| and base 2| are provided adjacent their peripheries with a plurality of equally spaced apertures to mount the charge receiving recepy tacles, each of which has upper section 65 which may be secured at its upper, end by weldingto wall 6| and base 2l, and lower section 66 telescoped within the slotted lower end of yupper section 65 and held therein by clamp 61. By adjusting sections 65 and 66 telescopically, the amount-of stock delivered by the receptacles to the associated containers can be varied. Sections 65 and 66 are of a diameter slightlyless than the diameter of the largest container with which the machine can be used. To adapt the receptacles for use with containers of smaller size, an adapter is provided comprising telescopic sections 68, 69 (Fig. 3), which are fitted in upper section 65 with lower section 66 removed. Upper adapter section 68 is provided with vertically spaced annular flanges 10 which t'closely within section 65, upper flange 10 being positioned to continue the plane of bottom wall 6| of the hopper, while lower flange 'I0 is held in the slotted end of section 65 byclamp 61. Such an adapter may be provided for each size of container smaller than the largest size. The closure element for the receptacles comprises annular channel shaped element 1| mounted for vertical adjustment on posts 1. For this purpose,

elementl 1| has a plurality of slotted bosses 12,4

each boss512 being clamped on a post 1, between nuts 13 by a suitable bolt. By loosening the clamping bolts and turning nuts 13, the closure element can be adjusted vertically and spaced in close cooperative relation with the lower open end of section 66 to retain the charge in the receptacles during fllling thereof. Closure element 'II (Fig. 1) has elongated arcuate opening 'I4 to provide for discharge of the contents of the receptacles into the respective containers moving in synchronism therewith as described hereinafter.

Associated with the rotatable bulk stock hopper are a plurality of stationary elements which cooperate with the hopper to mix the bulk stock thoroughly and deliver it to a discharge area whileV keeping the bulk stock away from the filling area for the individual stock feeders. Certain of such elements divide the area dened by outer'wall 63 of the hopper into compartments for mixing and feeding the bulk stock, for feed-A ing the individual stocks, and for discharging the mixed charge from the receptacles. Arcuate wall or fence 8| (Figs. 1 and 2) is secured as by welding to arms I0 and depends therefrom to space its lower edge in close cooperative relation with bottom wall 6| of the hopper. In the embodiment shown, wall 8| extends for substantially adjacent the individual stock feeders to provide an annular space between wall 8| and outerv wall 63 of the hopper which is free of the bulk stock, and in which the individual stocks are fed into the receptacles. Levelling fence or wall 82 is mounted similarly to wall 8| and extends` from outer hopper wall 63 inwardly at A just above the end of opening 14 in closure element 1I, then arcuately to a point adjacent wall 8| from whence it bends outwardlyV at B into the space between walls 63 and 8| for a purpose later described. The annular space between Awall 82 and outer wall 63 provides a discharge area in the hopper free of any-stock to provide for discharge of the receptacle charges into the associated containers. The compartment defined by walls 8| and 82 and inner and

outer walls

62, 63 of the hopper, provides the bulk stock mixing, and feeding area, in which the bulk stock is deposited as later described. An annular segment of this area over closure element 1I between end A of wall 82 and the adjacent end of wall 8| forms the filling area for the receptacles as described hereinafter. I'

In order to provide for proper distribution and mixing of the bulk stock in the hopper, a plurality of adjustably mounted mixing and spreading members are associated with the hopper. Each member comprises a vertically disposed plate 86 (Figs. 1 and 2) having slotted horizontal flange 81 along its upper edge for engagement with one of arms I0 or one of arcuate supporting members 88 which may be welded or otherwise secured between arms I0 adjacent the filling area of the hopper. All of arms I0 and members 88 are provided with a plurality of apertures 89forming fastening stations to receive the fastening bolts 9| of plates 86. By proper adjustment of plates 86, the bulk stock in the hopper can be mixed thoroughly as the hopper rotates and thereafter moved into the filling area and into the receptacles.

It is to be noted that walls 8|, 82 and mixing and spreading members 86 are adjustable vertically with the framework comprising members 88 and arms I0 of the 'spider assembly to provide for cooperative relation thereof with hopper 60 in any vertically adjusted position thereof.

lsuitable vertical and transverse braces Bulk stock elevator unit The elevator unit includes a mixing and feeding disc which receives the bulk stock, such as diced pears and peaches or the like, and an elevator which receives the mixed stock from the disc and delivers it to the bulk stock hopper, common driving means being provided for the disc and the elevator. The discharge end of the elevator is mounted for rotation and for vertical adjustment on the filling unit of the machine so that it can be placed in the most convenient location to the user.

The mounting means for the discharge end of the elevator unit includes a framework comprising spaced channels |0| (Figs. 1 and 2) which are connected by suitable cross members including platform |02 for motor |03 and angles |04 (Fig. 2). To mount the frame work removably on mounting bracket 23, channels |0| are spaced apart to fit between ears |05 (Figs. 2 and 4) of bracket 23, while angles |04 (Fig. 2) fit on either side of bracket 23. To maintain the elevator unit in assembled position on bracket 23, angles |04 are apertured to receive bolt |06 which extends through recess |01 (Fig. 4) of bracket 23. As described previously, bracket 23 is supported for vertical adjustment by the engagement of hub 22 thereof with vertically adjustable hub 20 of plate 2|, and can rotate about spindle I6 when it is desired to vary the angular position of the elevator unit with respect to the filling unit.

The elevator proper is preferably in the form of an endless rubber belt ||0 (Figs. 1 and 2) which extends about suitable drums and a supporting frame therefor. The frame is comprised of spaced apart top angles having side plates ||2 secured thereto in overlapping relation with belt H0, and similarly spaced apart bottom angles H3, all of said angles III, ||3 having a flange positioned to support and guide belt ||0. At the discharge end of the elevator unit, respective side plates ||4 are secured to respective pairs of angles and ||3 as by welding and Support bearings H6 for shaft ||1 having drum ||8 secured thereon in any convenient manner. Similarly at the pickup end, side plates ||9 connect angles I, ||3 and are mounted on base plate I2| (Figs. 8 and 9) of the elevator unit. Intermediate their ends angles ||3 are connected by (not shown). Bearings |22 (Figs. 1 and 8) for shaft |23 of lower drum |24 are similar, and each bearing |22 is mounted for sliding movement in a slot |25 of a bracket |26 secured on the associated side plate H9. Adjusting screw |21 has threaded engagement with bracket |26 and engages the associated bearing |22 to provide for adjustment of the tension on belt ||0.

At the pick-up end of belt ||0 (Figs. 1 and 9), mixing and feeding disc |3| is provided to receive the bulk stock, perform a mixing operation thereon, and discharge it onto the belt. Disc |3| is mounted detachably on hub member |32 which is journalled on shaft |33 and engages boss |34 of bracket |35 in which shaft |33'is secured. Above disc |3|, guide members are provided for the stock in the form of extension |36 of one side plate H9, and plate |31 secured to extension |38 of the other side plate H9, suitable reinforcing angles |39 (Fig. 1) being provided for extensions |36, |38.

Common drive means isprovided for the elevator and the disc including electric motor |03 (Figs. 1 and 2) mounted on platform |02. Motor |03, through drive sprocket |42, chain |43 and driven sprocket |44 on drum shaft ||1. drives belt ||0 in the direction indicated by the arrows in Fig. 1. The drive for disc 3| is transmitted through belt ||0 to lower drum shaft |23 which carries sprocket |46 (Fig. 8). Sprocket |46 is engaged by chain |41 (Figs. 8 and 9) which extends over idler |48 on shaft |49, and sprocket |5| (Fig. 9) 0n shaft |52. Shaft |49 is adjustably mounted in suitable slots in side plates 9 to provide adjustment of the tension on chain |41. Shaft |52 is journalled in spaced bosses |53 of bracket |35 and carries bevel pinion |54 meshing with bevel gear |55 on hub member |32. The drive is such that disc |3| is rotated in a counterclockwise direction, as indicated by the arrow in Fig. 1, to carry any stock placed thereon between arcuate guide extension |36 and guide plate |31 and onto belt ||0. When the stock reaches the discharge end of belt ||0, it is discharged through funnel member |56 (Fig. 1) into the bulk stock hopper.

Stock feeder with adjustable pockets One form of stock feeder disclosed herein includes means operable in synchronism with the charge receiving receptacles for measuring and discharging a uniform amount of stock into each receptacle as a part of the charge carried thereby, such amount being adjustable to correspond to the size of can being filled or to vary the proportion of the stock for different charges. To obtain this end, a series of adjustable pockets are provided which register successively with the discharge opening through which the measured amounts of stock are discharged positively.

The stock feeder includes hopper |6| (Figs. 2 and 10) of sheet metal detachably mounted in an inclined position on bracket |62 (Figs. 2 and 5) which is secured to one of pads 4 of base plate by suitable fastening means. Hopper |6| comprises cylindrical side Wall |63 (Fig. 10), annular bottom wall |64, discharge spout |65 at the high side of the hopper, and drain pipe |66 at the low side of the hopper, all the parts being suitably secured together as by welding. The upper edge of side wall |63 is formed at an angle to the axis of the hopper with the longer length at the lower side of the hopper to provide stock receivingportion |66.

The endless series of measuring pockets are formed by cooperating parts of discs |12, |13 which are relatively adjustable to vary the size of the pockets. For this purpose, lower disc |13 (Figs. 10 and 11) has axially spaced concentric strips |86 secured to the bottom side thereof as by welding and having their lower edges spaced in close cooperative relation with bottom wall |64 of hopper |6i. Disc |13 is apertured at equally spaced intervals between strips |86, and at one end of each aperture, a depending plate |81 (Figs.

Drive means' is provided for moving the series of measuring pockets successively through the stock receiving portion of the hopper and past the discharge opening, means being provided to remove any surplus stock from the pockets and to positively force the measured amounts of stock through the discharge opening. The drive means includes gear |19 (Fig. 2) which meshes with and is driven from gear |95 on shaft |98 journalled in spaced bosses |91. |98 of bracket |62. At its lower end, shaft |96 carries spur gear |99 meshing with spur gear 200 on shaft 20| which is joumalled in boss 202 of bracket |62 and at its upper end carries spur gear 203 meshing with main drive gear I9. The above described drive train moves the series of measuring pockets in a clockwise direction as viewed in Fig. 1. Thus, the stock feeder is driven in synchronism with the drive for the charge receiving receptacles so that each measuring pocket of the stock feeder will register with the discharge opening at the proper time toplace its contents in one of the receptacles.

To insure the proper measured amount of stock in each pocket, brush-205 (Fig. 1) is removably clamped on side wall |63 of the hopper just ahead of the discharge opening of spout |65 so that any surplus stock carried by a measuring pocket is wiped off and returned to the stock receiving portion. To provide for complete discharge of the stock in each pocket, nozzle 206 (Figs. 2 and 10) is 4mounted in aligned relation with discharge spout |65 by bracket 201 on wall |63. Pipe 200 also connected to bracket 201 leads from a suitable source of fluid pressure to provide a pressure jet of fluid, such as air or steam, to force each measured amount of stock out of a measuring pocket, through spout |65 and funnel 209 (Fig. 2) into the associated receptacle. Funnel 209 is removably mounted on wall 8| and serves to center the discharged stock with respect to the receptacle. In order to obtain eicient transfer of the stock therethrough, both spout |65 and funnel 209 are prefrably provided with a rectangular cross section. The longer dimension of the rectangle is parallel to the path of a receptacle moving under the rectangular discharge opening of funnel 209 so that the greatest effective area of the receptacle is available to receive stock. For the same purpose, the lateral dimension of the opening is preferably made slightly smaller than the smallest diameter receptacle to cut off the side segments of the circular receptacle opening which register with the funnel for the shortest period of time. Preferably, the relatively timing of measuring pockets |89 and receptacles 65--66 is such that discharge from a pocket |89 occurs immediately after a receptacle has passed by funnel 209, so that stock in such pocket will fall onto wall 6| and into the leading side of the next receptacle, the stock on wall 6| being raked oif into such receptacle by funnel 209. This timing is desirable to prevent cutting of stock between funnel 209 and the trailing edge of the receptacle opening.

The left hand stock feeder |6|A as viewed in Fig. 1 is similar in construction and operation to that described, except that pockets, |89A are usuallyof a different size than pockets |89 for handling different stock. For example, the measuring pockets of one stock feeder may be adapted -for use with grapes. while those of the other stock feeder may be adapted for handling diced pineapple.

Stock feederv with counting and preparing means A stock feeder of special construction is provided to prepare and measure a class of stock of the type such as pitted cherries and the like, which are preferably sliced into halves before being discharged into the receptacles, a definite number of the cherries or the like being counted for each receptacle. Generally, the feeder includes a hopper having an endless series of counting pockets with -which a cutter is associated to cut the units of stock carried by the pockets before discharge thereof.

Hopper 2|0 (Figs. 1 and 14) y.is generally similar to hopper |6| described above and is mounted similarly by bracket 2|| secured ona pad 3 of base plate Bracket 2| is similar in construction to bracket |52 except as to certain details of construction referred to hereinafter.

The series of counting pockets are provided by equally spaced apart apertures 2|2 (Figs. 14 and 15) in enlarged rim 2|3 of disc 2|4 which forms the bottom of the hopper and is mounted on shaft 2|6 for rotation therewith. Disc 2|4 may be formed of brass or other suitable non-corrosive material. Apertured rim 2|3 has its bottom surface spaced in close cooperative relation with annular bottom wall 2|1 of the hopper, so that apertures 2 |2 form an endless series of pockets, the size of which is preferably selected to hold one unit only of the stock being handled.

A cutter is associated with the series of pockets for halving the units of stock carried in the pockets before discharge thereof from the hopper. Disc cutter 22| (Fig. 14) is secured on the reduced end of sleeve 222 between collars 223 by means of nut 224. Sleeve 222 is pinned on drive shaft 225 of electric motor 226 mounted by bracket 221 on hopper 2|0. Cutter 22| extends through suitable slots formed in hopper 2||J and plate 228 secured thereon and into annular slot 229 formed midway between the surfaces of rim 2|3 as pitted cherries, will roll as they are elevated by movement disc 2I4, and that such rolling takes place about the stem-blossom axis with substantially all units of stock. Consequently, such units are presented to cutter 22| in a position to be halved through the stem-blossom axis.

The number of units of stock which are halved and discharged into the charge receiving receptacles is counted by selective timing of the rotation of disc 2I4 and pockets 2I2 with respect to the receptacles, and for this purpose a plurality of selected speed drives for disc 2I4 from drive gear I9 is provided. Shaft 2I6 (Fig. 14) carrying disc 2I4 is rotated through

gears

236, 231 from shaft 238 having spur gear 239 (Fig. 5) at its lower end. Gear 239 is driven from drive gear I9 through gear 248, shaft 24|, gear 242 carried thereby, and removably mounted gear 243 meshing with

gears

242 and 239. Gear 243 (Fig. 6) is journalled on the lower end of shaft 244 above an end ange thereof, the reduced upper end of shaft 244 being adjustably positioned in slot 245 formed in boss 241 of bracket 2| I. Slot 245 is of less width than the lower end of shaft 244 so that nut 248 threaded on the upper end of shaft 244 serves to maintain the selected adjustment thereof. By selecting the pitch diameter of gear 242 and adjusting shaft 244 in slot 245 to obtain the proper engagement between the gears, the speed of disc 2I4 can be adjusted to deliver one or more halved units of stock to each receptacle as it passes under spout 23| and funnel 246 (Fig. 1) associated therewith.

From the above description, it is seen that the described form of stock feeder serves to both prepare and count the units discharged into each receptacle. It is to be noted that the slicing of the units is performed in the preferable manner along the stem-blossom axis.

Container feed The containers for receiving the mixed charge of stock from the receptacles are moved through the lling unit in synchronism with the movement of the receptacles by feeding means which is adjustable to accommodate different sizes of containers. The feeding means includes a detachable container feeding unit for delivering containers to the filling unit, which comprises a feed disc which conveys the containers through adjustable guide members to a timing screw from which the containers are delivered through a star wheel in timed relation to the container feed of the filling unit. Feed disc 25| (Figs. 5 and 7) is secured on hub 252 (Fig. 7) and annular pad 253 of gear 254 journalled on shaft 255, which is secured by a suitable set screw in boss 256 of bracket 2,51. Bracket 251 is mounted on one of pads 4 of base plate I in accordance with the most convenient location for disc 25|. Gear 254 is driven through gear 258 from drive gear I9, gear 258 being secured on shaft 259 journalled in boss 26| of bracket 251. Thus feed disc 25| (Figs. 5 and 7) is rotated in a counterclockwise direction to feed empty containers placed thereon between outer guide strip 262 which extends around part of the periphery of disc 25| and inner guide member 263 which may be made as a casting and secured on shaft 255 above disc 25|. Guide strip 262 (Fig. 5) has one end secured to gear housing 264 which is mounted on bracket 251 and a post 1, and has its other end secured to guide member 266 which is supported adjustably by suitable bolt and slot connections with spaced brackets 261 (Figs. 5 and 7) mounted on guide member 263. Such adjustment of guide member 266 provides for proper positioning thereof with respect to timing screw 268 having one end journalled in housing 264. and the other in guide member 263. Screw 268 is of conventional construction and is driven synchror'iously with drive gear I9 as later described to deliver containers successively to star wheel 269 on shaft 21| mounted in housing 264. Wheel 269 is driven through

gears

212, 213, 214, and 258 from gear I9. The above train of gears also serves, through shaft 21|, gears 216, 211 (Fig. 5) and bevel gears 218, 219, to drive timing screw 268. Thus, both screw 268 and star wheel 269 are driven synchronously from drive gear I9 to feed empty containers from disc 25| over plate 289 formed integrally with housing 264 below star wheel 269 and past arcuate guide 280A which may be formed integrally with plate 280 to the container feed proper of the filling unit. If desired, container feed disc 25|, bracket 251 and associated parts can be mounted on the second set of pads 4 illustrated in Fig. 5.

The container feeder of the mung unit is dr1v.

en in synchronism with the charge receiving receptacles, and moves the containers in vertical alignment therewith for a part of their travel to receive therefrom the mixed charge of stock. The container feed as shown is adapted especially for cans and includes disc 28| (Figs. 2 and 5) supported on drive gear I9 and turret 282 supported in spaced relation on disc 28|, both disc 28| and turret 282 being held in assembled position by cap screws 283 extending through suitable apertures in disc 28| and through respective slots 284 in turret 282 (Fig. 5) to provide for adjustment thereof for a purpose later described. Turret 282 has a series of recesses 286 (Figs. 2 and 5) equal in number to the number of receptacles and positioned to receive the containers from star wheel 269 and to center the containers under their associated receptacles to receive the charge therefrom, as shown in dotted lines in Fig. 2. To provide for accurate centering of the receptacles with any selected size of container, disc 28| and turret 282 are each provided with a plurality of aligning apertures 281 (Fig. 5) to cooperate with aligning pin 288. Apertures 281 in disc 28| are unequally spaced with respect to apertures 281 of turret 282 so that alignment of any selected pair of apertures 281 by pin 288 results in adjusting turret 282 for the can of corresponding size. As shown in Fig. 5, the four pairs of apertures 281 adjust turret 282 for 8 oz.. No. 1 Tall, No. 2, and No. 21/2 sizes of cans.

Guide members are associated with the container feeding turret to maintain the containers in the recesses thereof, the guide members being adjustable to cooperate with different sizes of containers. As each container is moved from plate 280 onto disc 28| and into a recess 286 of turret 282 it is guided by guide member 29| (Fig. 5) pivoted at one end on shaft 21| at one end and having a slotted extension adjacent the other end to provide an adjustable connection with the adjacent bracket 261. After the containers move beyond guide member 29|, they are maintained in recesses 286 of turret 282 by arcuate guide strip 292 which has an end pivoted to guide member 29|, and has its other end adjustably connected to a post 1 by slotted link 293 pivoted to strip 292 and adjustably connected by a clamping bolt with end 299 of a guide member 296. During the filling phase of their travel, the

containers are carried between inner guide member 295and outer guide member 296. Inner guide member 295 has an end pivoted about a post 1 and is connected adjustably by suitable fastening bolts to slotted fiange 291 of .bracket 298. Inner guide member 295 is curved adjacent such end to extend inwardly over turret 282 to move the filled cans off disc 28|. Outer guide member 296 has slotted end 299 adjustably connected to a post 1 and at its other end is pivoted on shaft 30| of discharge disc 302 which receives the filled containers from disc 28| and turret 282. Thus, both inner and

outer guide members

295 and 296 which cooperate with the containers while they are being filled and discharged from the llingunit are adjustable to cooperate with various sizes of containers.

Discharge disc 302 and shaft 30| are mounted Operation The operation of the filling unit in placing the mixed charge inthe receptacles will now be described. It will be understood that the bulk stock, such as diced pears and peaches, are fed into the bulk stock hopper which is revolving s0 that spreader blades 86 (Fig. 1) serve to work the stock back and forth to provide thorough mixing and to deliver the stock to the receptacles at the proper time. Also, individual stocks, such as grapes, pitted cherries, and diced pineapple, are placed in the hoppers of the respective stock feeders.

If desired a small amount of bulk stock can be first deposited in the receptacles, and this is effected by positioning the spreader blade 86A (Fig. 1) mounted adjacent the adjoining ends of walls 8|, 82 in the dotted line position thereof so that a small amount of bulk stock can' pas's through the opening between walls 8|, 82 and into the receptacles as they pass part B' of wall 82. If such action is not desired, spreader blade 86A is left in the full line position shown in Fig. 1 to close the opening between walls 8| and 82.

As each receptacle travels beyond part B of wall 82 in the direction of the arrows, such receptacle passes under discharge spout |65 of hopper |6| just after a measuring pocket |89 filled with the desired number of grapes is aligned with spout |65, so that the measured amount of grapes is blown through spout |65 and funnel 209 into the receptacle by the jet of steam or the like from nozzle 206. As pointed out previously, the timing is preferably such that the discharge from pocket |89 begins at about the time the opening of a receptacle passes beyond funnel 209.

Thereafter, such receptacle passes under dis-.

charge spout 23| and funnel 246 to receive the sliced cherry halves blown therethrough, the number of cherries placed therein being determined by the number of pockets 2|2 which pass over spout 23| while the receptacle is in registry with spout 23| through the associated funnel. Subsequently, such receptacle receives its meascontents into such container.

ured amount of diced pineapple from hopper |8|A asldescribed in connection with grape hopper |6 After the measured amounts of individual stock have been placed therein, the receptacle moves beyond wall 8|'into the bulk stock filling area where spreader blades 86 `work the bulk stock back and forth over the receptacle to complete the filling action. In the continued motion of^the receptacle, it passes under leveling wall 82 which removes any surplus bulk stock to finish the receptacle filling operation. Thereafter, such receptacle moves over aperture 14 of closure element 1| into registry with a container entrained in container feeding turret 282 and discharges its This cycle of operation is continuous in the series of receptacles, so that an endless series of cans are fed through the filling unit in synchronism with the receptacles by feed disc 25|, turret 282, and discharge disc 302.

As referred to in various parts of the description, the machine is adjustable to accommodate various sizes of containers and as shown in the drawings, the machine is conditioned to fill No. 21/2 size cans.

The various adjustments of the machine to accommodate a smaller size can includes the lowering of closure element 1| (Fig. 2),.bulk stock hopper 60, and the spider assembly including arms I0 so that the closure element will be positioned immediately above the cans 306 on disc 28|, and the receptacles with suitable adapter sections 68 and 69 in closl v cooperative relation with closure element 1|, and with `mixing and spreading plates 86 and walls 8|, 82 in close cooperative relation with bottom wall 6| of the hopper. Also turret 282 is adjusted to place aligning bolt 288 in the aligned apertures for the 8 oz. size can for example, and the various guide members are moved inwardly to confine the cans to the proper space. Also a drive gear 46 of the proper pitch diameter to obtain the desired number of filled cans per minute is selected and installed, as well as the proper drive gear 243 for stock fee'der'2l0 so that the desired number of sliced cherries will be deposited in the receptacle.

In addition, the measuring pockets |89 and |89a of stock feeders |5| and |5|a are adjusted to the desired size can. Thus the machine can be easily conditioned for operation with any size container within the range of sizes provided by the adjustments of the machine.
