15 Claims.

The invention relates generally to the art of packaging foodstuffs and primarily seeks to provide novel means for filling measured quantities of liquid, such as cottonseed or olive oil, into containers used in the packaging of tuna fish or the like.

In the packaging of tuna nsh or the like, it is customary to include in the packaged product a quantity of oil. The oil is delivered into the containers while they are moving along toward the product filling machine or While they are passing from the filling mechanisms toward the closing devices, and it will be obvious that a desirable oil dispensingv apparatus of the nature stated must include means for assuring cooperative timing of the dispensing means with the traveling containers, as well as means for accurately controlling the amount of oil to be deposited in each container. It is an object of the present invention to efciently supply the means stated.

Another object of the invention is to provide a novel oil dispensing apparatus of the character stated in which is included novel means for varying the amount of oil to be deposited in each container.

Another object of the invention is to provide a novel rotor structure, a plurality of valve units movable with the rotor structure and individually engageable with the containers in which the oil is to be deposited and which are actuated by container contact so that no oil will be discharged from a valve unit unless a container is engaged thereby.

Another object of the invention is to provide novel means for feeding oil to the traveling valve units to be dispensed thereby.

With the above and other objects in view that will hereinafter appear, the nature oi the invention will be more clearly understood by following the detailed description, the appended claims, and the several views illustrated in the 'accompanying drawings.

In the drawings:

Figure 1 is a fragmentary vertical cross section illustrating the invention.

Figure 2 is a vertical sectional view taken on the line 2-2 on Figure 1.

Figure 3 is a vertical sectional view taken on the line 3-3 on Figure 1 and illustrates one form of mechanism by which movement may be imparted to the valve rotor.

Figure 4 is a horizontal section taken on the line 4-4 on Figure 1.

Figure 5 is a central vertical section through one of the dispensing valve members looking toward the manifold rotor. l z' Figure 6 is a fragmentary end elevation illustrating the vertical adjustment-'of the' apparatus and comprising a downward extension--ofFigure l at th-e line A-.--A.'v f v ;.;f

In the drawings I have illustrated 1a feed bed over which containers 6 are fed in suitably spaced relation by the feed dogs1 projecting upwardly `from the feed chain or conveyor; which may bel driven in any suitable manner (not shown). z,

A supporting bracket 9 is securedvtoand ex:- tends laterallyfrom the bed, andthis bracket in- 'cludes a depending 'guide columnp'ortion il equipped with an" adjustable supportin'g'screw vI'I. The screw .forms an adjustable support for .the lower end portion l2 of a standard l3f'vertically adjustablysecured tothe bracket 9'through the medium of the slot and screw equipment generally designated I4. The ystandard carries a drive mechanism housing l5 and'includes a bearing for a drive shaft I6 vto which rotation is` imparted in any suitable manner (not shown) 'for-the purpose of driving the shaft intimed relation with the feed chain 8. .f f1 1 An oil reservoir supporting bracket vI'l` is re.- movably secured as at I8 upon the housin'g'l and includes bearing portionsl I9 in which are secured laterally projected tie rods v2|), the purpose for which will later become apparent. An oil reservoir 2| is removably secured as at 22 upon the bracket I1. f I j A rotor plate 23 closes the inner facecf the housing l5 'and is equipped with three bearing hubs 24 which are equidistantly spaced about the center of said plate. Each-bearing hub24 rotatablysupports a stub shaft 25, and it will be observed by reference to" Figure 1 of the'drawings that the stub shafts project from'the `inner ends of the'hubs. Eachl shaft 25`has a valve member generally designated 26 clamped thereon as at 21, and each valve member includes a depending hollow body portion 28 vrvand an oil delivery duct portion 29, the latter 'terminating in a bearing hub 30 which is axially 'aligned with the respective stub shaft 25. I

Each duct portion 29 delivers into the interior of the respective valve member which is yclosed at the top by a ceiling web 3| and at the bottom by a circular valve cup `32 whichl is preferably threadably mounted on the valve body as at 33 lso that it can be removed and replaced at will.

Each removable valve cup 32 is provided with a circular discharge throat 34 which' is normally closed by a'flanged valvev member 35 having a .of the yvalvelmember;bearing hubs 3.0.

Any suitable means may be employed for im- :j

. ege' stem 36 secured theretoas at 31.. Each stem projects upwardly from the valve member which it supports and passes through a gland 38` in the respective ceiling web. A spring 39 surrounds each valve Istem between the respective ceiling web and valve member A35 and serves to yieldably hold said valve member on its seat so as to normally prevent passage. of oil through the respective` discharge throat 34. The portion of each valve stem' extended above the respective' gland 38 isthreadedk as aty 40 and provided with a v knurled head 4l. The threaded portion 40 of each valve stem is threadable in a sleeve 42 forming a part of a yoke structure 43 connectedat .its ends with two plungers 44 slidable in bores '.45 formed in the respective valve body 28. Each set of plungers f 44 extends a distance below the respective valve discharge throat 34, and each `plunger comprising the set carries a container ange engaging-foot 4At their laterally extended lends, the tie rods .20 carry-a bearing bracket 47|; `Abearing member -48 is `removably"securedto depend from the V'bracket 4'I'and has an oil receiving chamber 49 formed-in one Send thereof and closed `by a remov-able cap 50 and to which oil is delivered by tgavitf'y through a pipe or.l duct 15| from the resiervoir 2l, :avr sut'ablecutoff valve 52 being connected vin 'said pipe.-

As has been previously stated, any suitable means for maintaining the perpendicular positions of the valve units may be employed, and another-mechanism suitable for imparting the desired movements to the individual stub shafts 25 is disclosed in U. S. Letters Patent to Warme & Blood 1,341,437 of May 25, 1920.

In operation, as the individual containers are moved along in spaced relation by the chain 8, 'either toward a packing machine into which tuna sh or similar products are to be filled into the cans, or from such a packing machine after packing has been accomplished, they will pass be-` neath-and between the rotor elements 23 and 54.A The rotor elements` are driven in timed relation with the passing containers, and as each container mounted at the lower ends of the plungers 44 of one of the valve units will engage the flange of theconta-iner and will be pushed upwardly by the moving container.v As the plungers are rpushed upwardly the respective valvemembers 35 will be Vunseated and oil will pour Out of the Valve discharge throat :334 into the containeras :long as the valve member remains unseated. The amount of roil to be filled Vinto individual containers will vary accordingv to the product and the size of the container. a

By utilizing the housing position adjusting .equipments H and |.4 the position ofthe valve units with respect to the feed rbed 5 .can be altered to accommodate rthe feeding :of cans :of different sizes or `for simultaneously altering the rduration of contact of all ofthe valve vunits with the individual containers soV as to vary *the amount of oil'dispensed thereinto. f

It will `also be obvious that by merelyadjusting the knurled heads 4I of the valvestems the positionsof the plungers 44 of the respective valve units can Abe altered so .as to alter theduration of contact of the individual unitsfwith .in-
