' CAN-FILLING MACHINE.

Specification of Letters Patent. latented June 1922,

Application filed February 17, 1919. Serial Np. 277,398.

T 0 aZZ whom it may concern:

Be it known that I, AnNo SCHMIDT, a citizen of Germany (who has taken out his first papers as a citizen of the United States), residing at Hayward, in the county of Alameda, State of California, have invented a new and useful Can-Filling Machine, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same. I r

This invention relates to a machine for filling cans and its object is to produce a machine which will be capable of continuously tiliing cans as they pass through the machine and without stopping them during. I

' through the lug 24 and it IS operated by I,

surh movement.

Another object of the invention is to provide means whereby a measured quantity of the product may be placed into the tins and whereby such quantity may be varied as may be necessary for different sized receptaoles.

Another object of the invention is to provide a moving stream of the material being handled without the use of a movable nozzle.

Other objects of the invention will appear as the description proceeds.

Anembodiment of the inventionis shown in the drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there be modifications thereof.

Figure 1 is a side elevation partly in section of the complete machine,

Figure 2 is a view in elevation looking in the opposite direction from Figure 1,

Figure 3 is an end elevation of the complete machine,

Figure l is a plan view of the complete machine,

Figure 5 is a side elevation in section of a modified form of the feeding device in which two cans at a time are moved into position,

may end, which cross bars are secured in place a sprocket chain 11 which chain has/suit able flights 12 thereon to properly s'pace the cans as they pass through the machine. The shaft 8 is also provided with a hub 13 carry ing three

arms

14', 15, and 16 which position the cans with respect to the chain properly as they are placed upon the bed 1.

Near the center of the bed there is a flat.

post-17 which is provided with

vertical slots

18, 19 and 20. The two

slots

18 and 20 have cap s-rews 21 and 22 extending therethrough into the hopper frame 23. The hopper frame I which lug is for the purpose of adjusting the height of the hopper, a screw 25 being used for this purpose. The screw 25 extends means of a hand wheel 26 at its lower end.

Above the hopper frame there is the hopper 27 which terminates in a cylindrical shell 28 just in front of the hopper frame. This cylindrical shell is slotted at 29 and 30, the former slot being for the purpose of allowing material to pass into the measuring apparatus, and the latter for the purpose of discharging it therefrom.

has a lug 24 which extends into the slot 19,

Within the shell 28 there is another shell 2 32 which is provided with a pair of spiral I slots 33 and 34-, and which is divided into two compartments by means of the partition This shell has a cross bar 36 at each in the shell in any suitable manner and it has set screws 37 extending therethrough,

which screws have heads extending between two pair of

lugs

38 and 39 on shdable heads so, the object'being to adjust the sizes or the two chambers in the shell 32 as may be required for the given size receptacleto be filled. 5

The hopper frame has an arm '42 rigidly connected therewith which extends to and surrounds the vertical shaft 7. This arm also provides a bearing for a shaft 43 carry.-

ing a bevel gear 4:4: and a spur gear 45, the

latter in mesh with the ring gear 46 carried by one end'of the measuring shell 32.

The shaft. 7 has a feather way and drives a bevel gear d7 which is in mesh with the bevel gear 44; and as the hopper frame is raised or lowered the bevel gear 47 is raised or lowered.

The apparatus is driven from a pulley 48 on the horizontal shaft 6. The ratio of the gears is such that the cans will be moved into position under the spiral slots of the shell 32 just as said slots begin to discharge the material within the shell through the slot 30, and the cans will move along under said slots as the material is discharged therefrom until all of the material has been discharged therefrom at the opposite end of the slot 30.

In practice the hopper is filled with the material to be placed in the cans and as the compartments of the'shell 32 are filled when the slots are on the upper side of the shell the material will be discharged.therefrom through the slot 30 into the cans when said "shell turns 'to theopposite position and said cans will always be maintained under the main stream of material by the flights of the sprocket chain. The table 1 is slotted as indicated at 49 and the legs of the machine also support a shelf 50 upon which a suitable bucket 51 may be placed to collect whatever of the material may fall through the table 1 when it may happen that a can has not been placed in the proper position to be filled.

In the form 01" the invention shown in Figure 5 the outside shell is indicated at 60, the slots therein at 61 and 62, and the cans are arranged to be placed at 63 and 64 in such order as to be receiving material from two streams passing out'of the slots 65 and 66, oft-he revoluble shell 67.

In the form of the invention shown in Figure 6 the outer shell has the inlet slot 71 and outlet slot 72; while the revoluble shell 73 has a single continuous spiral slot 7%, the pitch of which is so arranged that three

cans

75, 76, and 77 will be filling at onetime.

Having thus described my invention, what I claimas new and desire to secure by Letters Patentof the United States is as tollows, express reservation being made of permissible modifications. I

1. A can filling machine comprising a hopper having an elongated slot, means to advance a series of cans longitudinally oi said slot below the same, a slotted cylinder revoluble in contact with said hopper the slotin said cylinder being formed to deliver a restricted stream of material from the hopper slot progressively along the same and into the cans as they pass thereunder.

2. A can filling machine comprising a ta ble, means to advance a series of cans thereover, a "feed hopper having an. elongated slot in its bottom underwhi'ch the cans pass, a spirally slotted cylinderrevoluble in contact with the feeding hopper whereby a restricted stream of material will be delivered from said elongated slot progressively along the same as the cans pass thereunder.

3. A. can filling machine comprising a table, means to move a series of cans along the table, a coding hopper having an elongated slot under which the cans move, means to adjust the feeding hopper vertically, a spirally slotted cylinder revoluble in contact with the bottom of the hopper for delivering a restricted stream of material progressively "from the slot in said teed hopper into the several cans as they travel under said hopper.

5. A can filling machine comprising a table, means to move a series of cans along the table in succession, a slotted teed hopper under which the cans pass, means to adjust the feed hopper vertically and a separate movable member in the bottom of the feed hopper having a slot inclinedto the hopper slot to deliver a measured stream of material into the cans as they successively pass under the feed hopper.

6. A can filling machine comprising the combination of a table ol means to move a series of cans along the same in succession, a feed hopper having an elongated slot in its bottom, revoluble double chambered cylinder in said hopper having a pair of spirally arranged slots, and means to rotate said cylinder so that the spiral slots cross the elongated slot immediately over the cans as they move under said elongated slot.

7. A can filling machine comprising a'table, a oonveyer to move a series of cans along the table in succession, a slotted "feed hopper under'which the cans move, a cylinder revoluble in the feed hopper and having two chambers with two spirally arranged slots, means to rotate said cylinder to deliver a stream of n'iaterial into each can as it passes under the feed hopper and means to adjust the size of the compartmei'its in said cylinder.

In testimony whereof I have hereunto set my hand this 31 day of January, A. D.

ARNO SCHMIDT.
