III!!! [N VENTOR 27 20 406057 APZ/No (4 NJ a y B Patented June 28, 1932 mxrmmm AUGUST 1?. ARZINO, OF SAN JOSE, CALIFORNIA FILLING VALVE FOR SIRUPERS Application filed April 11, 1927.

This invention relates particularly to filling valves especially adapted to siruping machines used in the canning industry, and particularly to valves for this purpose 5 adapted, the object of which is to enter a displacement body into the can, to automatically provide for the requisite volume of sirup in the can, preparatory to introducing the can or cans into an exhaust'box.

An object of the invention is to provide a siruping means embodying a valve of simple construction, provided with means thereon to enter the can to be siruped, the said means being adjustable to regulate the amount of sirup to be supplied to the cans according to the size thereof, and a device which is readily and conveniently removable for cleansing or repairs.

A further object of the invention is to provide a siruping valvefor cans in which the volume of sirup to enter the can may be varied according to circumstances and any excess sirup returned to the source of supply, and also to provide a valve for siruping the cans that will be well ventilated and will avoid undue pressure upon the relatively solid contents of the cans while being filled.

Other objects of the invention are to provide a siruping valve that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general efliciency.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the inven tion in whatsoever form it may be embodied.

In the accompanying one sheet of drawing Fig. 1 represents a vertical sectional elevation of a siruping valve constructed in accordance with my invention.

Fig. 2 is an enlarged cross section taken through the siruping valve structure.

ient displacement member to enter the can to be filled.

Fig. 4 is a plan View of the top side of the displacement member shown in Fig. 3.

In the drawing accompanying this application, I have deemed it sufiicient to only illustrate a single siruping valve in connection with only so much of the conventional assembly of a siruping machine as may be necessary for an understanding of the filling 0 valve structure, it being apparent that the details of the siruping machine per so have no bearing on the present case, and may be of any desirable character. The construction of my siruping valve and the displacement member thereon, through which the sirup is entered into the cans to be filled, is such that the drip from the valve after the requisite volume of sirup has been supplied I to the cans is practically eliminated, and in addition any excess amount of sirup deliv ered into the can is returned to the source of the sirup supply, thereby conserving in the amount of sirup being used, and doing away with the sirup being spilled over the cans. It has also been a practice heretofore to make the siruping valves out of material that has no give or resiliency, and as a result it is not readily possible to get the same close fitting contact between the valve and so the cans to be filled as in a case where the filling valve is provided with a resilient displacement member capable of adjusting itself to the contour of the can to be filled. The solid and non-resilient type of siruping valve has a tendency to crush or squeeze the can contents which is disadvantageous in can ning such tender fruits as pears, peaches and the like.

In detail, the construction illustrated in the drawing comprises the sirup tank 1 of a siruping machine, into the bottom of which is screwed at 2 the outlet fitting 3, formed with a circular projection 4: thereon. The outlet H fitting 3 is a part of the siruping valve to be 9;; hereinafter described. The screw end 2 of the fitting 3 has an extension continuing into the siruping tank 1 which is provided with ports 5 therein through which the sirup from the tank 1 may flow into the interior of the fitting 3. The end of the fitting 3 within the tank 1 is provided with a threaded support 6 thereon in which an air-eXit-duct or sirup return pipe 7 is adapted to be adjustably mounted. The duct 7 extends centrally with in the fitting 3 so that the axis thereof is concentric with the axis of the circular end 4 of the fitting. A lock nut 8 is placed around the pipe? to bear against the support end 6 of the fitting 3 to locate the pipe 7 in any selected position to thereby varyrthe distance that the concave center of the disc gasket 23 will extend into the can to befille'chwhenthe center of said concave center is deflectedby the valve 17 The base 4 on-the fitting 3 is circular in contour and forms a slide bearing fora cylin- .drical valve sleeve 9. The 'valve sleeve 9 telescopes within the circular base -4;.1I1(IlilS .reciprocatable therein. The valvesleeve is adapted for vertical movement on the base .ofthe outlet fitting 3, and a tight joint-between the-valve sleeve-and circular base is effected by arolling gasket 10 interposed in .an annulargroove 11 cut around the valve sleeve 9. The valve sleeve 9 has abase flange 12 thereon which is provided with a periph- .eral. shoulder 13011 the peripheral edge thereof, said shoulder beingiparallelto theaxis .of the-sleeve 9. An annular shoulder 14 e tendsoutwardly from the underface of-the flange 12 to form a continuation of the valve sleeve :9. The shoulder 4-is tapered exteriorally at 15 toward the faceof the flange 12 whereby the diameter vofthe annular shoulder 1 1 is'greater at its outer edge than atthe point where said annular shoulder joins to the flange. The inner edge 16 of the shoulder14 is beveled to provide a valve seat.

The valve sleeve9 is adapted to be slidably-mounted in the outlet fitting-4 and held in place thereon by a mushroom valve 17 that .is screwed into engagement with a threaded end'18of-the pipe 7. "The valve has anedge beveled at 19 .to seat againstthe beveled edge 16 of .the annular shoulder 14. l have foundthat a metal tometal contact-between the valve and valve seat does not insure .theuniform tight seating to prevent sirup leakages that can be effected by arranging a rubber edging20 aroundt-he beveled .valve seat 16. The resilient edging 20 is pliant enough to insure a perfect seat between the valve and valve seat, and hence eliminate any leakage or wastage ofsirup.

In order to maintain the reciprocatable valvesleeveS) in contact with the valve 17, I provide an expansion spring '22 around the circular' base 4 on the outlet'fitting :3. The opposite ends of the expansion spring 22bear against the outlet fitting 3-andthe flange 112 on the valversleeve :to keep the movable -.valve seat in-contact with the-stationary valveaintil such timeas the-tension ofthespri-ng isovercome to unseat the valve :and valve seat.

A disc 23 of resilient material is provided to fit within the circumferential shoulder 13 around the base flange and said disc has a recess 24: therein that engages the tapered, annular shoulder 14 projecting centrally from the said base flange 12. The tapered annular shoulder 14 provides suflicient grip when engaged inwthe recess 24: inthe gasket disc 23 to hold said gasket in fixed placement on the under side of the base flange. The

bottom f-ace '25-of'the"disc 23 has an annular projection 26 formed integrally therewith and 'extendingcentrally therefrom, the bottom face27 of .theannular projection 26 being dish shaped, concaved or bell shaped. The projection 26 .is in contact with the bottom face of. themushroomvalve 17. An opening 27 .is provided through the. centerof the projection-26 to register with the opening-in the pipe 7. A plurality of openings.28-are.

arranged adj acent-the lower edge of the projection 26 to communicateethe interior of the recess .24 in the disc;gasket with the-outer peripheral edge .of-the; projection 26 formed on the-oppositezface of the discgasket.

The diameter of-theprojection 26 is:substantially thesameas the inside diameter of the cam into'which the sirup is to be-placed.

The can 30 to be filledwithsirup is arranged beneath the siruping valverand (the can is:

elevated into contact with the disc-gasket'23 whereby the annular projection 26 on .the

said gasket 23 enters intothecanto be'filled and the beadededge 31 otthecan rests against the:bottomface 25 ofthe disc -gasket 23. The

The -sirup from the tank -1 enters the outlet fittings 3 and isstopped from discharging by the seatingcontact'between the valve -17-and valve sleeve :9.

The can is timed to stay under the siruping valve so that only a proper amount of sirup will be discharged. Should an excessive amount of sirup enter the can the same can be returned to the sirup tank through the pipe 7. When the can is being filled with sirup, the bottom 32 of the annular projec- 'tion 26 on the disc gasket 23 is forced downward into the can a slight distance, as shown in Fig. 2. Fig. 1 shows the projection 26 in the inoperative position before the can is moved toward the mushroom valve 17. The area occupied by the gasket 23 in the can during the filling operation serves to displace from the can a sufficient amount of sirup that will thereafter permit the can to be sealed with the proper volume of contents therein. The position of the displacement space thus determines the volume of sirup supplied, and this volume may be varied by regulating the position of the pipe 7 and the valve 17 for varying the extent of the penetration of the center of the resilient projection 26 into the can. The distance that the annular shoulder 26 with the concave face 27 on the bottom thereof is projected into the can by the valve, thus regulates the amount of sirup which will be filled in the can, and insures that the can will not be filled to overflowing with sirup. The resilient shoulder 26 on the gasket disc meets the outer edges of the can and also the solid contents of the can. The en gagement is soft enough not to damage or bruise the contents of the can, and is resilient enough to give way under pressure. When the can is full of sirup it is dropped away from the filling valve, and the valve sleeve 9 automatically engages the stationary valve 17 to prevent the dischar e of sirup from the supply tank. After the can is lowered, there is no drip from the filling valve due to the esilientseating between the valve sleeve and valve.
