16 Claims. (Cl. 226-109) This invention relates to filler-valves and mechanism for actuating such valves for use more particularlyY in connection with apparatus for filling containers having open tops and is an improvement upon such valves and mechanism disclosed in United States Letters Patent No. 2,592,846 granted to me on April 15, 1952.
While the general principle of the filler-valve and of its actuating mechanism, as disclosed in said patent, are employed in the present improvement, the construction of the filler-valve `body and the valve element, itself, have been materially modified and vsimplified resulting in an improved manner of operation.
The prime object of the present invention, therefore, is to provide. a new and improved construction of fillervalves of the kind referred to wherein the filler-valve and its actuating7 mechanism has less parts, is materially faster in its filling operation, requires less maintenance, is cheaper to manufacture, and is easier' to adjust and clean than heretofore.
Another object of the present invention is to provide a simple, positive and effective means on a 'filler-valve that will make a tight seal 'between it and the container, being filled, to prevent leakage therefrom and overiilling thereof during the filling operation, even should the ange or rim at the open end of the container be bent or deformed or if the container is tilted on its support under the fillervalve.
A further object of the invention is to provide a fillervalve with a valve element and vent tube that is free floating, within limits, to allow for over-travel of the fillervalve body to open said valve element whose opening and closing movements are controlled by the movement of the filler-valve body alone.
The objects of the present invention are attained, broadly, by constructing the valve body of two communicating sections positioned and mounted to have a relative axial movement and yieldably maintained against said movement in a normal position, when the filler-valve is in a non-filling position, said sections being sealed 'together to prevent leakage of the filling material and of air therebetween. The upper of saidvsections is actuated periodically to lower the valve-body into iilling position with a container, to be filled, -and to raise the valve-body out of filling position after said filling, the lower section being provided with a valve-seat at its lower end which is closed by a valve element normally biased upwardly to its closed position and positively opened against its bias by the relative axial movement of said valve-body sections toward each other. The lower section of the valve-body carries a sealing head having an annular sealing member of relative soft rubber or yieldable rubberlike material, the outerperiphery of said sealing member having an upstanding lateral flange projecting therefrom and axially thereof -so that, when .thevsealing member is mounted in its retaining head, there isa space between the body portion of said annular sealing member and the opposing surface of the head into which space the body portion of the sealing member yields, under .the pressure of the sealing head on the top rim of the can, and molds Patented Sept. 4, 1956 itself over and around the rim of the container filling-in alll unevennesses of the rim, such `as caused by a bent the improvement of this invention and shown in connection with portions of a conventional container support and filler tank or reservoir, the filler-valve and its actuating parts being shown in the positions normally occupied before a filling operation has begun;
Figure 2 is a viewnsimilar to Fig. l showing the parts in the positions occupied, when the filler-valve assembly and a container are in contacting relation, but prior to operationof the valve element for admitting owable filling material from the tank into the container;
Figure 3 Vis a viewsimilar to Fig. 2 but showing the valve element lopen for admitting filling material from the tank into the container; and
Figure 4 is an elevation of the sealing member of a form as used in filling small (6 oz.) cans.
The filler-valve of the present invention may be used in connection with filling machines of various kinds for filling containers, and the like, with various kinds of flowable materials, particularly liquids.
Referring in'detail to the drawings, in Vwhich like characters lof reference refer to similar and like parts, A denotes a bottom portion of a toroidal reservoir or tank positioned above a support or table B'for holding one or more containers C about to be filled from said tank by a fillervalve D. A plurality of the filler-valves D may be deployed about and carried by the bottom of the tank to provide a plurality fof filling stations over a plurality of containers on the table B. The tank A, support B and filler-valve D may turn around a -central column, not shown, in the manner of a turret, and, since the turret type of filling machine is generally known in the art, no detailed illustration of such machines are shown other than those shown in the drawings. Of course, it is understood that one or more of said filler-valves D may be employed in other arrangements or devices to meet other requirements. Y
The present invention resides more particularly in the construction and operation of the filler-valve D itself, and the means thereon for making 'a sealing contact with the container, to be filled, during theiillng-operation.
The filler-valve D comprises two'tubular communicating body sections 10 and 11, which may be designated, for convenience, as the upper lsection and the lower section, respectively. These valve-body sections, particularly the lower section 11, arepreferably, but not necessarily, cylindrical `depending upon the shape or type of the container C to be filled and are connected together at their adjacent ends by a liquid-proof means that permits relatively endwise or 'axial movement of said body sections 10 and 11. The presently preferred manner of accomplishing this is shown in the drawings ask having the lower end'of the upper section 10 reduced, as at 12, and extending for -a distance into and spaced from the upper end of the lowersection 11, said lower end of the upper section 10 and the upper end of the lower section 1'1 being connected by aflexible diaphragm or wall 13, which may be of rubber vor other suitable plastic or flexible material, .arranged 'to span the space between .said adjacent Vends 'of said sections.
The connection between the flexible wall 13 and the said ends of said sections may be accomplished in any convenient way but, in order to provide for quick disconnection as for cleaning lor renewal of parts, it is preferred that the inner and outer marginal edge portions of the exible wall 13l be releasably clamped `to said adjacent'ends of said sections 10 and 11. To this end, said marginal portions of the exible wall 13 are sandwiched between roughed or ridged washer rings 13e' and positioned on shoulders a and 11a formed on said sections, respectively, and clamped into position by rings 10b and 11b threaded onto the adjacent ends of said sections, the roughed or ridged surfaces of said washer rings being pressed into the marginsof said wall 13 to grip the same thus forming effectivelly sealed fluid-tight joints. The arrangement of the parts is to be such as to allow the sections 10 and 11 to have sufficient relative endwise or axial movement as will presently appear.
The valve-body sections'10 and 11 are biased to move axially away from each other. This may be accomplished by a helical compression spring 14 interposed therebetween, preferably, exteriorly thereof.
The upper end of the upperl valve-body section 10 is externally threaded to receive an end cap 15 having a centrally disposed outwardly extending tubular guidestem 16 projecting therefrom and having one or more ports 15a therein.
The lower valve-body section 11 has the inner surface of its side wall downwardly converging, as at 11C, to a discharge port 17, the circular wall of said port being flared or chamfered downwardly and outwardly to provide a circular beveled valve-seat 18 exterior of the section 11 for cooperation with the circular head of the valve member 19 having a complementally beveled edge 18a.
The valve member 19 is preferably of rubber or rubber-like material and is-centrally disposed and carried on the lower end of a hollow stem or tube 20 which ends through the valve-body sections 10 and 11 and through and beyond the guide-stem 16, the hollow valve stem 20 also serving as a vent tube as will later appear. The valve member 19 is normally biased to closed position on its seat 1S and this may be done by the provision of a helical compression spring 21 surrounding the valve stem at a point above the guide-stem 16, one end bearing against the outer end 162L of the guide-stem 16 and the other end bearing against a collar 22 adjustable on the valve stem 20. Another collar 23 is fixedly adjustable on the valve stem 20 and positioned thereon within the section 10 to form an abutment engageable by the under or inner surface of the end cap 15. The collar 23 is normally spaced from the cap-15, as shown in Figure 1, so as notto be contacted thereby until the filler-valve D has been brought down into sealing contact with the open end of an'underlying can or container C which arrests further downward movement of the lower valve-body section 11; then, upon further downward movement of the upper section 10 against the compression of the spring 14, the cap 15 abuts the collar 23, as shown in Figure 3 and moves the valve-stem 20 against the bias of the spring 21, which causes the valve member 19 thereon to move downwardly ofl` its seat 18 and open the discharge port 17.
The lower valve-body section 11 is provided with a sealing-head S for making a sealing contact with the open upper end of the container C and may be in the form of a rigid annular disc 24 surrounding and radially extending from the lower valve-body section 11 and slidably adjustable thereon in directions axially thereof. The disc 24 forms a backing for a yieldably compressible sealing-ring or gasket 25 disposed on the outer or downwardly facing surface thereof to engage and seal the top rim of the container C during the filling operation. The disc 24 is held rigid in its adjusted position on the section 11 by a split clamping band 26 also surrounding the section 11 and having a clamping screw 26a through its 4 split ends and being secured to the inner or top face of the disc 24 by screw 27.
Containers C fed to a filling machine occasionally are slightly tilted on the supporting table B or have the flange f at their open end bent or distorted causing an imperfect sealing contact with the sealing head of the filler-valves. Cans, that have their rim portion severely bent, are, of course, picked off the feed-line before they reach the ller; but some less severely bent are not readily detectable and proceed into the ller machine, and, in the past, have resulted in leakage, over-filling and spillage of the filling material as well as other inconveniences in line-production. It has been found that a rubber sealing ring or gasket 25 of the shape shown in the drawings permits those tilted cans or those having bent flanges or rims, that come into the filler-machine, to be properly sealed and overcome the drawbacks just mentioned.
The sealing-ring 25 comprises an outer annular part a that is positioned against the outer downwardly facing marginal surface of the rigid disc 24 and is retained thereon by a downwardly projecting rim flange 24a carried on the disc 24, said ange 24a having its free edge portion inturned to provide a retaining lip 24b extending under the part a of the sealing ring 25. The annular part a of the sealing ring has an integral inner marginal extension b, of less thickness than that of part a, projecting planarly from approximately the lower half of the inner edge of the part a so as to provide a space s between it and the opposing surface of the backing disc 24, thus the inner marginal extension b forms a selfsustaining yieldably resilient and freely movable ap. When a can C is brought into sealing engagement with the soft yieldable resilient sealing ring 25 (Fig. 2), the flange f on the rim of the can will, or should, contact the part b of 'the soft yieldable resilient sealing ring 25 slightly inward of its juncture with its part a; and further dewnward movement of the sealing head S compresses the relatively thin extension part b up into the space s, thus causing the flexible part b adjacent the part a to deform over and around the entire rim of the can compensating for any unevenness of the rim and filling any voids caused by distortion, bending and canting of said rim and thus making a tight seal between said rim and the sealing-ring 25.
In order to properly effect the sealing action just described, cans of different sizes will require sealing-rings 25 of different sizes, wherein the size or area of the parts a and b will vary; and, to this end, it is suggested that the following table may employed:
6 oz. l2 oz. 18 oz 46 oz can can can can Inches Inches Inches Inches Exterior diameter of Part aA 4% 4% 5 5 Interior diameter of Part a 2% 3%; 33t 4% Thickness of Part a 41 d Efo Va Interior diameter of Part b... 1%6 lflie 21%5 2K5/1e Thickness of Part IJ t l l a 1% e While the above table has been found satisfactory for cylindrical containers now commonly in use, it is to be understood that the above table is merely suggestive. The sealing-ring shown in Figs. l, 2 and 3 is that employed with cans designed to contain 46 ounces of liquid, while Fig. 4 shows a sealing ring for use in filling cans designed to contain 6 ounces of liquid.
The helical compression spring 14 surrounding the valve-body sections 10 and 11, at their adjacent connected ends, is preferably interposed ybetween the bears against the split clamping band 26 on the section 11 and an abutment flange 28 projecting outwardly from the section 10 above its reduced portion 12.
Filler valves D of this invention may be carried in a rcircular series by the tank A and mounted thereon for relative vertical movement. To this end, and as shown,
each filler valve may be mounted in an opening 29 formed in the bottom of the tank A and connected by a exible annular diaphragm or wall 30, which may be of rubber or other `suitable plastic or exible material, arranged to span the space between the body of the llervalve D and the wall of the opening 29. The underside of the opening 29 is counter-bored to provide a shoulder 29a and the upper valve-body section 10 is provided with a shoulder under the rim edge portion of its end cap 15. The marginal portions of the flexible wall 30 are placedupon the shoulders 10c and 29e, respectively, and are clamped in place by the rim portion of the cap and by a ring 31 threaded into the counterbored portion of the opening 29, respectively, suitably roughened, ribbed and ridged ring washers 15bv and 31a being interposed between the marginal portions of the wall 30 to press into and grip the same.
The filler-valve D is guided in its vertical movement and held against lateral movement by a guide arm 32 disposed within the tank A and detachably secured to the bottom wall thereof adjacent the opening 29 therein by a screw 33. The arm 32, preferably, is inclined upwardly and has its free end formed with a guide opening 32a centrally disposed over the opening 29 and into which the guidestem 16 on cap 15 extends with a sliding lit. The upper end of the valve-stem projects upward through the tank A above the liquid level therein and, thus, provides a vent tube for the escape of air from the container C during the filling operation.
The filler valve D is lowered into and raised from filling position with an underlying container C on supporting table B by means of an actuating lever 34 pivoted, at 35, on a bracket 36v secured by screws 37 to the bottom side of the tank A. The lever 34 is provided at its inner end with a cam follower roller 3S co-operable with the cam track E usually supported on a center supporting column, not shown. The outer end of the lever 34 is forked to provide upper and lower bifurcated portions 39 and 40 spaced vertically with respect to each other. Also, pivoted on the bracket 36, as at 41, is a valve-body operating lever 42 comprising two arms 43-43 spaced horizontally and connected by a cross-strap 44 adjacent the pivot end of said lever 42 and positioned to lie between the bifurcated portions of lever 34 to provide an abutment adapted to be alternately engaged thereby on its opposite sides, the spacing of the bifurcations 39 and 40 being such that, when the cross-strap 44 is engaged by the bifurcation, the other is out of contact therewith and spaced therefrom for a distance. The lower bifurcation 40 is provided with an adjustable contact abutment 40av to engage the cross-strap 44 and a similar adjustable contact abutment 44st is carried by the cross-strap to contact the upper bifurcation 39. The adjustable abutments 4t)a and 44a may be conveniently provided in the form of set-screws, threaded in the parts as shown, and held in their adjusted positions by jam nuts n. The arms 43-43 extend to opposite sides of the valve-body upper section 10 and are `suitably-slotted at 45-45 to receive gudgeon pins 46-46 fast with the body section 10, suitable means 47 being provided to releasably maintain the arm 43 and pins 46 against accidental disconnection.
When the lever 34 is rocked counter-clockwise (as viewed in Figs. l, 2 and 3) motion is transmitted from lever 34 to lever 42 to move the filler-valve D, as a whole, downwardly by its upper bifurcation 39 contacting the adjustable abutment screw 44a threaded through the crossstrap 44 which rotates the lever 42 anti-clockwise on its pivot to bring the sealing-head into engagement with the top of the container C as shown in Fig. 2. At this point further downward movement of the lower valve-body section 11 is substantially retarded by the contact of the sealing-head with the rim of the container; and as the movement of the levers 34 and 42 continues, the upper valve-body section 10 moves downwardly relative to section 11 and against the bias of the compression spring 14.
This continuing downward movement of the upper valve` body section 10 for a distance of about 3/16 inch, and the compression of the compression spring 14, exerts pressureA which causes the rim of the can to embed itself into the sealing-ring 25, in the manner above stated, thus, arresting further downward movement of the section 11 and establishing a firm sealing engagement. However, at this point in the continued downward movement of the upper valve-body section 10 by the action of the levers 34 and 42, the under-surface of the end-cap 15 engages the abutment collar 23 on the valve-stem 20 (because of the shortened distance between the end cap 15 and the port 17) and moves the valve-stem downwardly against its bias 21, causing the valve 10 to open downwardly ot its seat 18 to the position shown in Fig. 3. In its open position, the conical valve member 19 coacts with its seat 18 to provide a downwardly Haring annular detlector for the filling liquid, flowing from the tank A through the discharge port 17, directing it downwardly `and divergingly so as to llow toward and along the side walls of the container C. Air displaced from the container by the inowing liquid will escape through the vent passage 20a in the valve-stem 20, either to the atmosphere` or to a source of vacuum.
After a predetermined lapse of time, the cam-follower 38 will have arrived at a position on the cam track E as to cause they actuating lever 34 to be rocked clockwise (as viewed in Figs. l, 2 and 3) out of contact with the contact abutment 44a so as, rst, to relieve the compression on spring 14 and allow it to move the valve-body section 10 upwardly instantaneously relative to the lower valve-body section 11 which, together with the spring 21, causes the valve member 19 to return immediately to its normal or closed position on its seat 18. Continued clockwise movement of the lever 34 then causes the adjustable abutment screw 40a, carried by the lower bifurcation 40, to contact the underside of the cross-strap 44 and move the lever 42 upwardly about its pivot to lift the filler-valve D, as a whole, upwardly to the position shown in Fig. l, thus breaking the sealing contact of the valve D' with the can and allowing the same to be passed on to a can closing machine.
It will be observed that the sealing-head S is adapted to be adjusted vertically with respect to the bottom end of the valvebody section 11 for varying the extent to which the lower end of said section extends into a container C, thus controlling the volume of liquid deposited into the container.
It will also be observed that the provision of the adjustable abutments 40a and 44a permit adjustments to be made in determining the timing and amount of positive movement transmitted from thek actuating lever 34 to the filler-valve D.
The filler-valve D and its mode of operation, in accordance with the present improvements, increases the rapidity of the filling operation and renders the assembly, as a whole, much cheaper to manufacture because of the simplicity and less number of its parts than heretofore and is much easier to disassemble for cleaning purposes, thus 'fullling the objects of this invention.

A filler valve for filling containers, comprising a valve-body having a discharge port therein and adapted to be brought into and out of engagement with a container to be iilled; and a sealing means on an annular surface of the valve-body, that opposes a container during a filling operation, for making a fluid seal contact with the rim of the container; said sealing means comprising a yieldably resilient cushion material carried by said surface and surrounding said port and positioned to be brought into engagement with the rim of the container, said cushion material being formed to provide a thick outer marginal area in abutting contact with said surface and to provide thinner inner marginal area spaced from said surface, the outer faces of said outer and inner marginal areas of said cushion material being planarly extensive and being dimensioned to have the rim of a container, to be iilled, contact said thinner area thereof near its juncture with said thicker marginal area and move said thinner area in said space toward said surface and bend the same at its juncture with the thicker area around the rim edge of the container, when the valve-body and the container are pressed together.
13. A ller-valve for iilling containers, comprising a valve-body having a discharge port therein, a sealing means carried by and surrounding the valve-body and said port to contact the rim of the container, said sealing means including a rigid retainer member having a surface that opposes the rim of the container, a yieldably resilient annular gasket of rubber-like material having a thickened outer marginal area thereabout ttedly disposed on said surface of the retainer ring and having a thinner marginal area extending inwardly from an inner edge of the thickened area and spaced from said surface of the retainerring, said gasket being dimensioned to have the rim of the container, with which it engages, contact said thinner area thereof near its juncture with the thicker marginal area.
14. A sealing means for use with sealing-heads of iillervalve, wherein the sealing-head includes a retainer ring for supporting said sealing means; said sealing means comprising a yieldably resilient annular gasket of rubber-like material having a thick outer marginal area thereabout adapted to be iittedly positioned in retainer ring in abutting relation therewith and having a thinner inner marginal area planarly extensive with and extending inwardly from one edge of the inner circumference of said thicker area to provide a freely movable flap, said gasket being dirnensioned so that, when the rim of a container con- 10 tacts said ap near its juncture With the thicker marginal area, said flap bends against the thicker area and over the rim of the container to fill the voids or unevennesses in said rim.
15. The subject-matter of claim 6, wherein the said means for moving the valve-body in opposite directions includes an abutment member operatively connected with the said first valve-body section and an oscillatory actuated member having spaced parts arranged on opposite sides oi said abutment member to alternately and positively contact and disengage said abutment member in opposite directions of movement of said oscillatory member to reciprocate said valve-body sections; and adjustable contact elements between said abutment member and said spaced parts of the oscillatory member, whereby the timing and amount of positive movement transmitted from said oscillatory member to said valve-body section may be controlled.
16. The subject-matter of claim 6 wherein the said means for moving the valve-body in opposite directions includes an actuated lever having a bifurcated end, a valvebody operating lever having one of its ends connected to the said first section of said valve-body and having the other of its ends pivotally mounted, said valve-body operating lever having a part positioned between the bifurcations of said actuated lever to be contacted by one of said bifurcations alternately in each different direction of movement of said actuated lever, the spacing between said bifurcations being such that when said part of the valvebody lever is contacted by one bifurcation, the other bifurcation is spaced considerably from said part, and adjustable contact elements between and carried by said part and said bifurcations thereby to control the timing and amount of positive movement transmitted from said actuated lever to said first section of the valve-body.
