Lacey, Lodi, Calif., assignor to Coast Machinery Company, Lodi, Cali?, a co-part~ nership Application January 11, 1937, Serial No. 119,902 15 Claims. This invention relates to can ?lling machines, my principal object being to- provide a machine for‘ the purpose by means of which measured quantities of produce of di?erent kinds (such as 5.‘ different fruits to form fruit cocktail) may be transferred from a hopper unit into cans without any manual attention being necessary other than keeping the hoppers ?lled. By means of this machine all the cans are ?lled to the same extent and all contain the same percentages of different ingredients. While the machine is particularly designed to thus supply different ingredients to the cans, it can be used, if desired, and without change to ?ll cans with one ingredient only. Another object is to provide an automatically functioning device to tamp certain kinds of pro duce into the receptacles of the machine as said receptacles pass under the hopper. This feature is of particular use in connection with sliced 2o ‘peaches and the like which have a tendency to (01. 226—100) straight, form a continuous unbroken surface. The boards are relatively short so that they can pass about the sprocket wheels without forming unyielding straight surfaces of any great length. The wheels 3 are driven at a. slow speed by any suitable means in such a direction that the upper runs of the chains move upwardly or in the direc tion of the wheels 3. The boards along the upper run of the chains form the bottom of a produce hopper 6 which 10 is divided by a transverse partition '1 into a pair of compartments 8 and 9, the compartment 8 being relatively small and being at the low or initial end of the hopper. » ‘ Secured in and projecting at right angles from the outer faces of alternate boards are cylindrical receptacles H], the bottoms of which are formed by plungers, and which have the same capacity as the cans into which the contents of the recep- ' tacles are to be discharged. Each plunger is. 20 jam against each other and not properly ?ll the - connected to a yoke l2 which slides in guideways receptacle. !3 on the sides of the corresponding receptacle. A further object of the invention is to produce The yoke is arranged so that the plunger may a simple and inexpensive device and yet one move from the bottom of the receptacle to a which will be exceedingly effective for the pur~ position ?ush with the outer surface of the pose for which it is designed. boards. Movement of the various yokes and These objects I accomplish by means of such plungers is controlled by rollers M on the sides of structure and relative arrangement of parts as the yokes riding in endless cam tracks l5. ’ These - will fully appear by a perusal of the following as or specification and claims. In the drawings similar characters of reference indicate corresponding parts in the several views: Figure l is a side view of my improved machine partly in section. Figure 2 is a fragmentary longitudinal section of the machine showing the hopper unit and the upper row of receiving receptacles. Figure 3 is a fragmentary transverse section on the line 3—3 of Fig. 2. ~10 ' Figure 4 is a similar view showing‘ a modi?ed form of hopper‘ and metering device. Referring now more particularly to the char acters of reference on the drawings, the machine comprises a suitable frame I on which are mount 45 ed transversely spaced pairs of longitudinally spaced sprocket wheels 2 and 3. These wheels are of different sizes, the wheels 3 being consider ably greater in size and disposed relative to the l DC wheels 2 so that their lower edges lie in a common horizontal plane as shown; the upper edges of . the wheels 3 being thus correspondingly higher than the upper edges of the wheels 2. Taut chains 4 pass about the sprocket wheels and support boards or plates 5 which extend 55 therebetween and which, when the chains are tracks are arranged so that the plungers are at the bottom of the receptacles as the latter pass under the hopper and are at the outer ends of the said receptacles when the latter are inverted and pass along the lower horizontal run of the chains. Said run of the chains is above and par— allel to a conventional can conveyor l6 moving at the same speed as the chains and receptacles and on which the cans ll are disposed; said cans being spaced the same as the receptacles and being disposed in registering relation therewith. - gs 0 Interposed in the hopper compartment 8, clos ing the same just above the boards 5 is a rotary metering device l8 having a series of circumfer entially extending pockets E9, the width and length of which at the periphery of said device 45 being no greater than the diameter of a recep tacle ID. This device is disposed so that when one pocket is open to and receiving from the hopper compartment, another one is discharging into» a receptacle. The device is intermittently rotated an arcuate amount equal to the distance between adjacent pockets in timed relation to the movement of the receptacles by 2. spoke mem ber 21] connected to the axial shaft 2! of the device outwardly of the hopper, said spokes being 55 2 2,111,071 successively engaged by pins 22 projecting at in tervals from one of the chains. The size of the pockets is such that each only holds enough produce to partially ?ll a recep tacle, the receptacles being subsequently ?lled to capacity by the produce contained in the main hopper compartment 9, which produce is freely open to‘ the boards 5 and the receptacles depend ing therefrom. Due to the upward slope of the 10 bottom of the hopper (as formed by the boards 5) the produce tends to remain at the lower end of the hopper, so that the likelihood of any conges tion of the produce at the upper end of the hop per is avoided. However in order to prevent pos 15 sible excessive ?lling of the receptacles such as would tend to cause a congestion of produce as the receptacles pass under the upper end of the hopper, I mount a transversely extending brush 23 in the hopper adjacent its upper end. This is 20 positioned to sweep across the top of the recep tacles and dislodge any excess produce therefrom, so that said receptacles pass from under the hopper in a properly ?lled condition. To prevent the produce spillingout from the receptacles as 25 the latter are moved about the sprocket wheels 3 to an inverted position, a guard plate extends from the hopper about and close to the boards 5 concentric with the wheels 3. To lightly tamp down the produce dropping 30 into the receptacles from the main hopper com partment 9 I provide a rotary device comprising a plurality of spokes 25 radiating from a verti cally movable transverse shaft 26 and having en~ larged rounded heads 21 adapted to enter the 35 receptacles for a certain portion of their depth. The end portions of the shaft extend through vertical slots S in supporting brackets B mount ed at the sides of the hopper, so that the shaft can move up and down acertain distance with out restraint. These heads are arcuately spaced the same as the spacing between the receptacles and the device is rotated by the engagement of said heads with successive receptacles. The weight of the device (which may be added to by any suitable means if necessary) is sufficient to exert the desiredtamping pressure on the pro duce in the receptacles, and if the produce is sufficiently dense without tamping the shift lifts of itself so that the heads do not enter the recep~ 50 tacles to unduly compress the produce. The metering device and hopper compartment 3 as shown in Fig. 3 is intended to meter only one kind of produce. If two metered ingredients in small quantities are desired as is sometimes the case, the compartment 8 is divided by a longitu dinal partition 28 into a pair of transverse com partments 8a, and the pockets of the metering device I80. are each divided into a pair of smaller transversely separated pockets Ilia as shown in Fig. 4. From the foregoing description it will be read they have passed beyond the hopper; there being means to support cans in position to directly re ceive produce from the inverted receptacles. 2. A structure as in claim 1 with a brush in the hopper adjacent the end thereof toward 10 which the receptacles are moving to sweep over the tops of the receptacles passing thereunder. 3.
