curren sr -Tes rATENr OFFICE ormnnns H, AYARS, OF SALEM, New JERSEY, Assrenon ro Areas; MAQHINE COM- rANY, or SALEM; new JERSEY, A CORPORATION on NEW JERSEY CAN FILLr vG' MACHI E" Application filed r eh The present invention relates" to can'lhlling machines and particularly to thesupplying of measured quantities of liquid as juice'or An ob'ect of the 1nvent1onis to improve machines of the above character. Further objects are to provide,- in acan filling machine, an improvediefl'ective and sim ple arrangement whereby liquid may be sup,- plied to cans in measured quantities, and to provide a constructionvand arrangement of parts whereby the quantity of liquidfso de livered may be variedaccording to the requirements of the commodity being canned.v A 1 Further objects are to provide, a simple adjustment of the partsfor varying'the quanf tity of liquid to be delivered and'toprovide' associated therewith indicating means show} ing the quantity to be dispensed. j

I These objects are accomphshed by a. mm-i her having spaced pockets therein and mean's,

for controlling the supply v of: liquidcto said pockets at certain positions and means jcontrolling the discharge thereof to the cansat certain other positions. The liquid 'issu plied to the pockets by'submerging the poo eted member in a pan and providing means for admitting the liquid thereto at the said positions which are-located between the discharge positions. The 'panjis provided with spaced dischargeopenings between which and the pocketed member there is relative movement to bring said openings and pockets into'registrat-ion successively as thepan and pocketed member are given relative movement. I r

A. member is provided for control of the discharge of thepockets'through the openings in the pan which is adjustable. fordetermining the number of pockets discharging for each relative movement or cycle of move-' ments of the pan and pocketed'member. The

adjustment is accomplished by providing groups of aperturesyin the control member ranging from one in thefirst groupto a num'- ber corresponding to thetotal number ofdis charge openings in the pan and mounting the control member fortravel across the open ings in the pan; the openings in the control member being spaced so that when the first 'urin'g solids. .r Y i W Figure 5 lsfa v1ewofthe juice pan with- 1929, Serial No. 344,230.)

" Figure 6 is aviewsh'owing the under side of the juice pan-jandi showingthe grouping of the apertures in thecontrolmember and the relation thereof to the apertures in the juice pan. f s -Figures 2 to 6 inclusive show the parts as in the same relation namely, the second position of the apertures in the control ring with the various parts in position for discharge therethrougl p I Figure 7 is a fragmentary detail showing the manner of detachab'ly securing the control ring to the bottom of the juice pan.

Figure 8 1s a detail showing the overflow from the pan and the supplemental reservoir uring cups are integral and such part is connected with thelsha ft l-i which is rotatedby the driving shaft of the machine (not shown). Th'e lower sections ofthecups are telescoped with the upper sections and will naturallybe carried ajlongtherewith as they revolve also revolving the turret 15 with which the lower sections are integrally formed. 7 p

The juice pan isprovided with adischarge aperture 16 for the measuring cups and with a plurality of spaced openings as indicated at 17,18 and 19in Figure 5ofthe drawings. There maybe any number of thesevopenings according to the given situation. In the present 1llustrat1on, three of such openings are shown which will illustrate the prin ciples of the invention without limiting the o enin in the an.

applicantto any definite number.

Connected with the juice pan is a control member in the form of a ring 20 shown clearly in Figures 1 and6 having a plurality of groups of apertures 21, and 22and the single aperture 23, spaced to correspond to each preceding group of greater number that when the first aperture of the greatest group first opening in the next smaller group will beopened and whenthe third opening inthis largest group is brought into registration,

theuopenings corresponding to the first three positions will be opened and so on for any number of openings in the'pan.

Mounted within the pan and, as shown, forming a peripheral extension of the turret 15 is the juice measuring member provided with a plurality of pockets 24,25, 26, and 28,'one corresponding to each of the meas- The apertures are so positioned relative'to the apertures 1n the nring cups. This turret, as clearly shown in Figure 1, rests flush against the bottom of the pan and has a movement relative thereto and in the present instance, the turret is revoluble relative to the pan which latter is relatively stationary in its position. These pockets are so positioned that they are brought by the revolution of the turret successively into registration with the openings in the pan, the pockets being open both' on thetop and bottom sides thereof.

As will be observed by reference to Figure ,4 of the drawings, the pockets constitute apertures in the said peripheral extension about which are formed upstanding marginal ribs constituting a deeping thereof and located'between these pockets areribs 29 which are spaced from the marginal ribs to permit a free flow of the liquid from one side to the other of said pockets, beneath a stationary member actingas a cover member 30 for the pockets.

This cover member isin the form of aring to correspond with the path of travel of the pockets and the openings therein are positioned to lie bet-ween the various discharge openings in the pan. These openings are clearly illustrated in Figures 2 and 3 of the drawings and are designated bythe reference characters 31,132, 33, 3e and 35, the latter three constituting in effect one opening and being of greater extent than the others due to the greater space available therefor,;inasmuch'as' the discharge openings are located in a sector of acircle corresponding to substantially half of the .periphery at hand.

Thus it will be seen that as the pockets [revolve, theywill be refilled between each discharge opening that is free :to discharge under the regulation of the control ring 20. The ring 301s operatively mounted in any suitable manner as by cleats or brackets 36 secured both to thelringand to the juice .pan.

The mounting of the "control ring 20 is shown in Figures Gand 7 by meansof spring fingers '37 preferably .OfSPring material attached to the bosses 3 8 ,on the bottomot the pan by means of screws 39. Theztension .of these fingers on the control ring may be regulated by the set screws 40 located intermediate bosses 38 and the ring 20 as clearly shown in Figure 7 01? thedrawings.

The proper centering of the control .ring is accomplishedbyforming on the bottom side 7 of the pan an annular shoulder 41 as :shown inlFigures Land 7 otthe drawings, and the turning movement of this ring is accomplished by an arm d2 connected with and BX- tending radially from the ring to a position of convenience ,for the, operator of the :ma-

'chine. This arm or handle is provided with an indicating pointer 13 adapted to .benioved together with the turning movement of the ring over certain calibrations 4L4 formed on the side of the ju'ice pan. There is oneof these points for each position ofthe control ring relative to theopenings at each posi tion of the control ring, for bringing apertures thereof into registration with'one, two, three and so forth openings in the pan, the position for closing the apertures being short of the first of these calibrations and indicated by thezero designation as shown inFigure9. V

The juice'pan as shownin Figural of the drawings is located above the hoppers at for directing the material to the receptacles i6 on the receptacle moving. turret 47. These receptacles are fed onto this turret and remain thereon through "a partial revolution of the said turret when they are directed off and conveyed away in any suitable manner. In the meantime, a measured quantity ofmaterial has been deposited in each of the recep tacles together with the s itable number of measured quantities of juice or preserving fluid, the number of shots to each can being dependent upon the condition of the fruit or vegetable being canned and upon the netural guicinessof this commodity.

The discharge apertures in the juice panare therefore positioned so as to correspond with. the path of travel of cans on the turret and the arrangement of the control ring is such that the adjustment thereof to the. apertures in the pan may bemade by a Comparatively slight angular movement of the said ring. The jUlCQ-Pdll is provided with an overflow reservoir 48 separated from the main pan by the wall 49 which is depressed A slightly below the upper. plane of the wall number of openin s 50 and from thisreservoir a pipe 51 leadsto any suitable receptacle which may be provided carrying oil the surplus liquid from the juice pan. i Of course, the filling machine illustrated maybe modified and changedin various ways without departing from the invention herein set forth and hereafter claimed.
