NVhile the 1 present I description employs relatively specific descriptive terms, such specific description should not be" construed as a -lnnitation-of the-scope of the present invention. Although ithe machine illus-. trated hereinis especially adapted to fill ,opentopped sanitary tin cans, the-term can should be construed as, designating any type or-form'of receptacle; The term filing is not intended to designate com-- plete filling only butjalso designatesa par tial filling of the receptacles. The machine described may be operated with both granular. material and a liquid, or with either of these substances alone, 'The features of-the Qpresent invention are applicable-to various types ofmaclnnes for automatically feeding I succesof .devices constructed in accordance therewith, may be had by referring to the drawlugs, accompanying and-forming a part of this specification in which like reference characters des gnate' the same or similar Fig. l -is a centralverticalsectionthrough' an improvedfinterchangeable automatic can filling machine. 1 v s I Fig. 2 is a"transversehorizontal section through .theimproved interchangeable automatic can filling machine, the section being.

The mam frame of the lnterchangeable automatic can filling inachincnompr ises a:

liquid supply and discharge pipes 26; re-

spectively. The upper portion ofthe side frames 17 also provides.v a support forthe stationaryvertical adjustable top plate (5 which forms a carrier for the pea or other granular material supply hopper 5. Lo-

cated directly beneath the stationary top plate'6 is an annular series of sevengranular material measuringpockets which: is rotatable about the central verti'cal axis ofthe machine and the successive pockets of which are successively communicable directly with the hopper 5 through-an opening in-the top plate 6. The granular material measuring pocl ets areformed in telescopic upper and lower members 7, 8' respectivelv; which may be relatively vertically adjusted in order to vary the volumes of the successive batches of granular material measured therein. The lower member 8 is slidable in direct engagement with a stationary cut-off plate '9'which rests directly upona circularrotary upper mixture measuring element 10 and is pro vided. with an opening for establishing di rect communication between the granular material measuring pockets and the mixture measuring pockets 30. The lowermeasuring member Sinay be drivingly direct connected with the upper mixture measuring element 10 by means of one or more drive pins 31'. The upper mixture measuring"element 10 rests directly upon one of a number ofintcrchangeable circular rotary intermediate mixture measuring elements 2, 3', l, these coacting elements being drivingly connected by means of one or more motion transmitting pins 32. The intern'iediate mixture measuring element 2, 3,4 rests directly upon a lower circular rotary mixture measuring element 11, these coacting elements being d'rivingly connected by means of one or more motion transmitting pins 33; v The superposedand interconnected mixture measuring elements are provided with vertically aimedopenings forming an annular series of seven mixture measuring, pockets of equal fixed capacities depending upon the particular intermediate measuring element 2, 3, 4 which is employed. V V, c g a The; lower rptar-y.'nrixtu-ree measuring element 11 is rotatably supported upon a stationary, cut-off plate 12 which is supported directly by the stationary upper cross frame 132 The cut-ofFpl ate'lQ is circular in form and is provided with liquid admission openings 38 con'iinunicating with a manifold 37 which in'turn communicates with the liquid. supply tank 28 through a control valve36 and the pipe 29. The cutoff-"plate 12 is also provided with a final discharge open ing for delivering measured quantities of mixture directly from-the successive -111 3J.S- uring pockets 30 to the successive cans 19 through the successive delivery chutes 1 4; The annular series'of delivery chutes 14 is supported directly by a rotary carrier 15 which embraces the vertical main shaft 21 and is rotatable witlrthis shaft. The sue ces'sive canslSJ-are-urged along a horizontal can supporting surface formedupon the stationary intermediate cross frame 18, by means of interchangeable can hooks 16, each machine preferably being provided with several sets ofcan hooks l6 and with several guides cooperablle withthecairhooksin order'to accommodatecans 1901? various stand.

ard sizes. The mechanism for delivering the successive cans 1'9 toand from the ma-' chine, and the guides'which cooperate with the can hooks 16', are clearly shown and described in Patent No; 1,460,198,, granted June 26', 1923. i v

The vertical main shaft 21 is rotatably mounted in bearings supported by the cross f'rames13, 18andha's its upper end detachably 'drivingly connectedwiththe lowermix-- turemeasuring element l l'by means of a removable driving head 34; 'Thelower portion of the shaft 21has a bevel gear 20 secured thereto; the gear 20 beingdrivingly connect ed withthe can hooks 16 andwith the chute carrier 15 bymeans o-f'a plurality of vertical ClTlVG rods as shown in Fig. 1. The horizontal main power shaft 23 is mounted in bearings supported by the cross frame 18 andone of'the side frames 17 and has a bevel pinion 22' attachedto an end thereof and meshing with the bevel gear 20'. A driving pulley 2 f carried by the power shaft Q-SVis d-rivingly connectable with the shaft 23' by means of a jaw clutch 27 whichis manipu lable automatically by means of safety stop mechanism, and manually by means of a l1and lever'25 which also functions to controla valve in the pipe 26, as shown and describedin copending; application Serial No. 435,835 filedJanuaryBL, 7921.

During normaloperation of thefillerand assuming the product handled to 'be peas and loo ' otherwise treated to complete the packingthrowntovvard the left as viewed in Fig. 1, the jaw'clutch 27 is thrown' into operative* position and the flow control valvein the pipe 26 is simultaneously opened, whereupon the horizontal power shaft 23, pinion 22, gear 20 and vertical main shaft 21'are rotatcd and brine is automatically {admitted to the supply tank 28 until'the ordinary float control in thetank 28 prevents further' admission of brine. The rotating shaft- 21 and gear 20 transmit their motion" to thecan hooks 16, chutes 14, mixture measuring pockets 30 and pea measuring members 7, 8. The can hoolrslG transport the successive cans 19 beneath the chutes 1 1. The peas are auto:

matically delivered from the supplyfhopper 5 through the't opplate ti to the successive measuring pockets inthe members 7, '8

from which the measured quantities" or batches of peas are delivered" through the cut-off plate 9 to the Successive mixture measuring pockets 30.-- After the successive measured batches of peas ha'vejbeeu deposited in the successive pockets -30,fbrine is automatically admitted to the pocketsBO from the manifold/37 through theopening 38, the brine thus admitted being under pres sure and percolating upvvardly through the voids in the'peas thereby filling the pocket-s30, v V

siredzto limit the invention tothe exact 'de:

with measured quantities of mixtureot' peas and brine. lVhen the filled measuring-pockets '30 advance to a position above-the" final discharge opening in thedovver cut-off plate 12, the measured batches; of mixture are delivered by gravity through the chutes 14 tothe successive cans19 located below the chutes. The cans thus filled are automatically delivered, from the machine in the usual manner and are subsequently capped and operation. It will thus be noted that' the machine automatically'and rapidly delivers to each of the successive cans19ofa series, accurately measured quantities of mixture of peas and brine.

The proportion of peas and brine comprismg each batch of mixture maybe readily varied by merely adjusting the volume-of the pea measuring pockets such adjustment being effected by shifting the upper member 7 vertically relatively to the lower member 8, adshowriand described in PatenflNo'. 1,460,198, grantedJune 26,1923. As thevol umes of the chambers 30for' a given size'of intermediate element 2, 3, 4, are fixed, variation of the measured quantities of peaswill,

naturally proportionately varythe quantities of brine in the final measured batches of mixture. Ifit'is desired to fill cans 19 of a different standard 7 size, :itl is necessary, only to substitute an intermediate element 3, 4'

corresponding to the size of the" cans. Which it is desired to fill, and to provide a set of canhooks 16 and'cooperating guide capable of properly coactingfwith the selected size of cans 19. Asthevarious elements of the 'machine which are adapted to be inter changed, are freely vertically removable and conveniently insertible,-the change in condition of operation of the machine may bereadily effected in a short period of time. As each machine is provided with several I sets of interchangeable measuring elements 2, 3,4, can hooks 16, and can guides, cans-19 of any desired capacity within the range of the interchangeable elements provided may befilled at Will. v v r i i From the foregoing description-it will be obvious nature mechanism isacapable of-au tomaticailly delivering to successive cans 19 ofa series travelling ata high riate-ofspeed,

accurately measured batchesof mixture of peas and brine. w The machine isadapted for convenient conversion. :for operation in filling cans 19 of differentstandard'sizes.
