To to whom it may concern.-

Be it known that I, EMIL METZENAUR, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Can-Filling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

Myinvention relates to can-filling machines; and it consists of the novel construction, combination, and arrangement of parts hereinafter described and claimed.

My invention relates to that class of canfilling machines wherein a large number of cans are continuously filled with a powdered or finely-granulated product.

Figure l is a side elevation of my improved can-filling machine. detail sectional view taken approximately on the line 2 2 of Fig. 1. Figs. 3 and 4: are side elevations of rotating paddle-shafts made use of in my improved machine. Fig. 5 is an end elevation of one of these paddle-shafts. Fig. 6 is an enlarged transverse sectional view taken approximately on the line 6 6 of Fig. 1.

Fig. 7 is a vertical sectional View taken ap proximately on the line 7 7 of Fig. 6. Fig. 8 is a transverse sectional view taken approximately on the line 8 8 of Fig. 7.

In the construction of my improved machine an elongated box-framework 1 is constructed, from the center of which rises a rectangular chute 1. Along the top edge of the box 1 extends a rail 2, and immediately below said rails 2 and on the inner faces of the sides of the box 1 are the strips 3, the up: per outer corners of which are cut away, as indicated by 4:, in order to form a track, and immediately below said strips is arranged a plate 5, the same extending between the sides of the box 1 and from one end to the other thereof. Formed in saidplate 5 immediately below the chute 1 to the right-hand side thereof is a plurality of longitudinally-extending slots 6.

Secured to the inside faces of the side walls of the box 1 a short distance below the plate 5 are the rails 7, and extending downwardly from said rails 7 and toward the center of the box 1 are the inclined walls S,wl1ich, together With the bottom 9, form a hopper that extends from a point beneath the chute 1 to the right- Fig. 2'is an enlarged hand end of the box 1, and in the bottom of said hopper is arranged a spiral conveyer 10.

Shaft 11 is rotatably arranged in fixed bearings at the right-hand end of the box 1 in approximate horizontal alinement with the plate 5, and in the left-hand end of the box is rotatably arranged a similar shaft, the ends of the same being journaled in longitudinallyadjustable bearin gs 12. Arranged upon these shafts inside the box and adjacent the sides thereof are the sprocket-wheels 13, over which pass the sprocket-chains 1 1. These'sprocketchains 14 on the opposite sides of the box are connected at intervals by the transverse bars 15, and the upper portions of said chains ride in the tracks formed in the upper portions of the strips 3, while the lower portions of said chains ride upon the rails 7.

Normally occupying a groove 16, formed in the inside face of the right-hand one of the rails 2, is a longitudinally-extending bar 17, the same being arranged at a point belowthe chute 1, and said bar is laterally adjustable by means of the thumb-screws 18, the same passing through the right-hand rail 2 and engaging against said bar. The purpose and function of this bar will be hereinafter set forth. Arranged within the lower end of the chute 1 are three transversely-arranged hoppers 19, the same tapering toward their lower ends, and arranged in the extreme lower end of each of said hoppers is a transversely-extending shaft 20, the same beingprovided with a pair of oppositely arranged blades or paddles 21, each of said blades or paddles extending from the end of the body of said shaft 20 to the center thereof. Arranged upon each end of the outside pair. of these shafts 20 are the sprocket-wheels 22, and arranged upon the front end of the central one of said shafts 20 is a sprocket-wheel 23.

Extending transversely through the chute 1 and in the upper outer corners of the outer pair of hoppers 19 are the shafts 24, the same be ing provided with a plurality of alternatelyarranged oppositely-extending blades or paddles 25, and upon each end of each of said shafts 24: are fixed the sprocket-wheels 26.

Connecting the left-hand one of the sprocket-wheels 22 with the left handone of the sprocket-wheels 26 on thevfront of the machine as viewed in Fig. 1 is a sprocket-chain too function of these various sprocket-wheels and sprocket-chains is to impart the proper rotary motion to the paddle- shafts 20 and 24, which operate in the hoppers 19.

Arranged to operate longitudinally through the lower ends of the hoppers 19 is a cut-off plate 31, the same having a plurality of openings 32, arranged to coincide with the passages through the hoppers 19, said plate 31 being moved by a screw-rod 33, passing through a block 34, fixed upon a bar 35, that is arranged at the left-hand side of the chute 1. The object of this cut-off plate 31 is to regulate and cut off the flow of the product that is being canned through the lower ends of the hoppers 19.

Arranged upon each end of the chute 1 is a pair of transversely-extending bars 36, in the centers of which are positioned vertical guide-plates 37, in which guide-plates are arranged for vertical movement the blocks 38. Projecting laterally from the lower ends of the guide-plates 37 are blocks 39, through which pass hand-screws 40, the same engaging the blocks 38. Extending laterally from each of the blocks 38 are rods 41, the same being formed integral with the upperends of the vertically-arranged rods 42, the lower ends of which are connected by the transverse bars 43. These bars 43 occupy planes just beneath the lower ends of the hoppers 19 and are connected by the plurality of longitudinally-exten'dingbars 44. The objectof these longitudinally-extending bars 44 is to evenly distribute the material or product that is passing from the hoppers 19 into the cans that are being slowly moved along the plate 5. Standards 45 extend upwardly from the left-hand end of the machine,and journaled in suitable bearings fixed-to said standard is a pair of shafts 46 and 47. Fixed upon the shaft 47 is apulley 48, that is driven in any suitable manner, and arranged upon the outer end of said shaft 47 is a small sprocket-wheel 49, the same being connected by a sprocket-chain 50 with the sprocket-wheel 22 on the front end of the right-hand one of the shafts 20.

Arranged upon the shaft 46 is a pair of sprocket-wheels 51 and 52, the sprocket-wheel 51 being driven by a sprocket-chain 53, that passes around the small sprocket-wheel carried by the shaft 48, and passing around the smaller wheel 52 and a sprocket-wheel 54, fixed upon the end of the shaft 11,is a sprocketchain 55. The object of these rollers, shafts, sprocket-wheels, and sprocket-chains is to impart the proper rotary motion to the shaft 11, which drives the endless carrier, comprising the sprocket-chains l4 and bars 15, and also to impart the proper rotary motion to the hand of the chute 1 right-hand one of the paddle-shafts 20, from which the various other paddle-shafts are driven, by connections heretofore described.

The operation is as follows: Rotary motion is imparted to the shaft 47 by driving the beltwheel 48 in'any suitable manner, and thus r0- tary motion will in turn be imparted to the shaft 11 by means of the sprocket-chain 53, sprocketwheel 51, shaft 46, sprocket-wheel 52, sprocket-chain 55, and sprocket-wheel 54, which is located upon said shaft 11, and to the right-hand one of the shafts 20 by means of the sprocket-wheel 49, carried by the shaft 47, and sprocket-chain 50, which passes around said sprocket wheel 49 and around the sprocket-wheel 22, carried by said shaft 20. The remaining pair of shafts 20, together with the shafts 24, will be rotated, owing to the sprocket chains connecting the sprocket- Wheels carried by said shafts, and consequently the paddles carried by said shafts 20 will operate in the lower ends of the hoppers 19, and the paddles carried by the shafts 24 will operate in the upper ends of the outer pair of hoppers 19. The sprocketchains 14, connected by the transverse bars 15, forming an endless carrier, will be slowly operated owing to the difference in size between the sprocket-wheels 52 and 54, which sprocket-wheel 52 is much smaller than said sprocket-wheel 54, and the cans to be filled are placed in the spaces between the transverse bars 15 and upon the plate 5, said cans being thus positioned immediately to the left The longitudinallyextending bars 44 are adjusted by means of the hand-screws 40 until they occupy a plane just above the tops of the open cans, and as said cans are drawn along by the endless carrier to a position beneath the lower ends of the hoppers 19 the powder or pulverized product to be canned passes downwardly through the hoppers through the openings 32 in the cut-off plate, which has been moved so as to bring said openings into coincidence with the passage through said hoppers,and, finally,said product discharges through the lower ends of the hoppers between the bars 44 and into the cans. The rotating paddle shafts at the mouths of the hoppers 19 agitate the product as it is discharged into the cans and together with the longitudinally-extending bars 44 cause said product to be very evenly and uniformly distributed into said cans. The paddle-shafts 24 operate at the upper ends of the outer pair of hoppers 19, and thus prevent any clogging up of the product at the heads or upper ends of the hoppers. The overflow from the cans or the excess product that passes downwardly between said cans lodges upon the plate 5, and as it is scraped along by the slowly-moving cans it will enter and pass through the openings 6 in said plate and pass downwardly into the hopper, in which operates the spiral conveyer 10. .By said spiral conveyer it is moved to the righthand end of the machine, and from thence it is taken in any suitable manner and carried back to the upper end of the chute l. The cans after being filled are moved along the plate 5 until they pass from beneath the chute l where they are taken out of the machine, and the tops are then placed upon said cans, after which they are labeled and packed. Should there be any space between the row of cans adjacent the adjustable bar 17, said space may be taken up by manipulating the screws 18 to move said bar inwardly.. Thus said cans are prevented from moving laterallyduring the time they are passing beneath the mouths of the hoppers.

A can-filling machine of my improved construction possesses superior advantages in point of simplicity, durability, and general efficiency and can be used for filling cans with any finely-powdered or disintegrated product.
