Thefannular rotary distributing member 3V surrounds-.the .stationary top plate! 2 and isprmfidedr with an Y annular4 seriesoi1 down wardly directed openingslr located closely' adjacent to the periphery ot the plate 2.

The outer edge of the member 3 is prefer#V ably downwardly and inwardly inclinedand the inner edge of `the member 3 1s preferably :termed as an apron 16 adapted todirect liq-fl uid downwardly toward thecentral axis of the machine. An annular seriesl ofl can hooks 8 are located one adjacent to eachot-y the openings 15, the can hooks 8 and the member Bbeing secured to a common spider which is rigidly attachedto the upper"` eX- tremity ofthe driving sleeve 5. The sleeve 5 isirotatably. supported upon athrustbearing 25 secured to` the stationary rod 4', and is' rotatable about the rod 4 by means of -ar worm wheel 27 coacting witha worm 40'secured' to one end of thecounter-shaift lilith the elements thus arranged. it will be.

noted that as the top plate' 2-and spider 24 are vertically` adjusted,- the member 3'- and can hooks i 8 are simultaneously vertically adjusted.

The upper portion ofthe main frame 6 is provided with a curved can track orrunway 7 disposed below the pathV of `the openings 15 and of the hooks8. The inlet anfd dis-v charge ends of the runway 7 may beinclmed 1n order `to raise andlower .the cans 19 relatively to the openings 15.` Aserlesfot readily removable Y arc-.shaped can guides 23- are located above the Vrunwa 7 7andseiwe.teg`

The pan 12 may be provided with one or more drain openings 18 for discharging liquid to a suitable conductor. openings 17, apron 16 and drip catch pan 12 insure rapid and effective delivery ot excess liquid from the machine.V j

The machine yis supplied with empty cans 19 by means of a can guide 14 which is capable of depositing the empty cans 19 in succession upon a continuously revolving tapered feed drum 10. The revolving tapered feedv drum 10 is secured to the main driving shaft 30 which is rotatably support ed in bearings inthe main frame Gand the inner end ofwhich-isprovided with a bevel gear v29-which meshes'with abevel gear 39 secured to? the counter-shatt 28; The delivery en'dsofv the feeddrum lisqprovidet with a helical projectionl Srwhich is` capable of gently delivering thesuccessive canszin properly spaced relation against the successive advancing can hooks 8.

Thelled cans 19 are delivered 'from the machine by. means of automatic discharge mechanism 37 driven byworm gearing 38 associated with the counter-shaft 28. This discharge mechanism is oi well known con struct-ion and requires no detail description herein. The main driving shaft 30 which communicates motion through the countershaft 28 to the various movable elements ot the machine, is normally rotated automatically by means of motive power applied to the driving pulley 3l and from thence,

through a jaw clutch 32 to the shaft 30, but may be-interchangeably operated manually by means of a hand wheel llsecured to the outer extremity oi the shaft 30. The clutch 32 may be manipulated either from the feed sideofthe machine by direct movement ci thel clutch operatingl lever 42, or it may be manipulated 'from the discharge side ot the,

machine by indirect movement of the lever 42-through a lever 36 anda cross connection 34.

The material supply means disclosed in Figs. 1, 2 and 5, comprises a relatively large stationary hopper .9 located' adjacent to the periphery ofthe stationary top plate 2 and havinga lower discharge opening arranged directly above the movable openings 15 oi the member 3. rlhe hopper 9 is vertically adjustably supported upona bracket 21, ver tical adjustment of the hopper 9 being etfected by means of anA adjusting belt Q2. The lower portion of the hopper 9 is provided with a pair or" curved walls or ex tensions .33formed to guide-the material deliveredirom the' hopper inthe' general direction' otadvancement of the openings 15. Af downwardly extending ridge or projec-- tion 44 located adjacent to: theV discharge Opening et' tlieilioppeeQ serveses het; back rl-he drain for relatively large 'pieces of material.V .A horizontally pivoted flap 41 located between the extensionsv or walls 33 also serves to .check the flow of material from the hopper 9 in the direction of advancement of the openings 15. The lower extremity of the flap 41 is preferably curved as indicated in order to produce uniform distribution of the material, and the fiap 41 is preferably provided with an adjustable stop 43 for limiting the upward movement of the flap about its supporting piv ot.

The material supply means illustrated in Figs. 3 and 4 comprises a relatively large chute 45 upon which certain materials may be deposited in bulk. The material thus deposited upon the chute 45 may be drawn with suitable scraping implements or by hand upon the stationary top plate 2, from whence the material may be delivered to the cans 19 through thesuccessive openings 15.

During normal operation of the semi-automatic can filling machinedisclosed in Figs. 1, 2 and 5, the various movable elements of the` structure are simultaneously set in Inotion by applying power to the drive pulley 31 and by throwing in the jaw clutch 32.'

The empt cans 19 aredelivered by gravity` through t e supply chuteI orV guide 14i and are deposited by gravity upon the rotating can feed drum 10. The helical -projection 35 of the feed drum 10 `automatically de livers the successive emptycans 19 to the successive 'advancing can hooks 8. As the cans 19 engage the hooks 8, they are automatically positioned with their upper open ends directly below and in vertical lalinement with the openings 15 ofthe revolving member 3.V The successive cans 19'are then urged along the runway 7 vand guides 23 until theyreach the hopper 9 `whereuponmaterial from the hopper is automatically;A deliveredy by'V gravity through the openings 15 and into they subjacentfcans 19 substantially. filling .the

cans. Other material from the hopper '9i is urged past the flap 41 by means of the advancing member 3, the fiap 41 and projection 44 automatically1 serving to prevent excessive delivery of materialfrom the hopper 9. The material thus delivered `from the hopper 9 past the flap 41 and projection 44 is conveyed between theextensions 3 3 where the cans 19 are further'automatica-lly filledV with material. -As the cans 19 and the member 3 are urged beyond the ends of the extensions 33, those cans which have not been properly automatically filled, are completely filled by one. or more operators stationed about the periphery of the machine, these operators ordinarily removing rexcess material from one` or more of the overfilled cans 19 and utilizing such material to properly supply the underfilled cans. Inasmuch as the cans 19 must travel considerable, distance beyond the ends ofthe extensions 33 before ,Y

they are delivered from the machine,-the operators `have suiicient time to insure proper filling of all of the cans 19 even when the machine is being driven at maximum speed. The filled cans 19 are automatically discharged from the machine by means of the delivering mechanism 37 in a well known manner. `It will be obvious that the succesin quality to a hand packed grade. The operators are exposed to but a relatively small amount of moving structure and are'protected against injury by the stationary top plate 2 and by the stationary guards 20 secured to the can guides 23. These guards 20 also serve to prevent splashing of thev liquid over the attendants and upon the floor. Excess liquid from the material handled, is automatically and effectivelyy discharged from the machine by the openings 17, the apron 16 and the drip catch pan 12,`thereby preventing undesirable accumulation of liquid and drippings rupon the' machine frame and fioor. v Due to the fact that prac-` tically the entire filling operation is automatic, the machine may be operated at relatively high speed to produce maximum ca.- pacity. The projection 44 and flap 41 also serve to reduce the manual labor and to enhance the capacity of filling by automatically controlling thel discharge of material from the supply hopper 9. i 1

Practically all ofthe elements ofy themachine may 'be quickly and conveniently removed for inspection and cleaning. The hopper 9 and the elements associated. therewith may be'freely vertically.removed at any time. lThis is also true of the modified supply chute 45. The stationary central'top plate 2 may be removed by merely releasing theclamping nut from the upper` end of the rod 4. The sectional canguides 225 and the guards 20 attached thereto mayv also be bearing 25, sleeve 5, dan hooks 8V and member 3. The canV hooks 8, 'member 3v and can guards 23 may be readily removed and other elements substituted in order toV accommo.

CII

date cans 190i different sizes; Thel adjusting screw 22 permits ready vertical adjustment of the suppl)T hopper 9,V thus enabling adjustment ot all of the more important elements with extreme rapidity.

The driving mechanism is also ot eX- tremely simple and compact construction and is controllable from various places around the machine. Manual operation 'ofthe machine may be ei'iected by merely throwing out the jaw clutch 32and manipulating the hand wheel 11 and the mechanism may be quickly started and stopped when desired.

It should be understood that it is not desired to limit the invention to the exact details oi' construction and operation herein shown andv described, for various modi ications within the scope ofthe claims may occur to persons-skilled in the art'.

It is claimed and desiredfto secure by'Letters Patent i said plate and'having an inner downwardly directed apron, and a drip catch pan'below said openingsand said apron.
