OLA]? LARSEN, OF FOR-T ATKINSON, WISCONSIN, ASSIGNOR TO THE CREAMERY PACK- AGE MFG, COMPANY, OF CHICAGO, ILLINOIS, A CORPQRATION OF'ILLINO'IS.

BOTTLE-FILLER VALVE.

T 0 all whom. it may concern:

Be it known that I, OLAF LARSEN, a citizen of the United States, residing at Fort Atkinson, in the county of Jefferson and the State of lVisconsin, have invented certain new and useful Improvements in Bottle-Filler Valves, of which the following is a specification.

The invention relates to the valves e1nployed in liquid container filling apparatus for controlling the discharge of liquid from a reservoir into the bottles or other containers and more particularly relates to such valves in apparatus adapted to the bottling of milk.

The usual construction of such apparatus includes a reservoir from which depend one or more discharge tubes, each having a terminal discharge orifice controlled by valve mechanism operable by contact with the bottle to be filled.

It is an object of this invention to provide a filler valve in which the opening and closing of the discharge orifice is accomplished positively so that any accumulation of thickened liquid or slight friction between the parts will not cause the valve to'adhere to its seat and fail to open, as often occurs when the opening operation is effected by gravity alone.

Another object is to provide a reversible valve seat, thereby enabling immediate repair without material loss of operating time in case of injury to the seat and conseql'ient leakage from the valve orifice.

Other objects and advantages will be apparent in the following description of a preferred embodiment of my invention which I have selected for illustration in the accompanying drawings.

In the drawings, Fig. 1 represents a vertical sectional view of a discharge tube and controlling valve mechanism in closed position. Fig. 2 is a similar view of the parts in open position. Fig. 3 is a planof the parts viewed from the interior of the supply reservoir. Fig. 4 is a horizontal sectional view taken on the plane of the line 44 in Fig. 1. Fig. 5 is a detailed view of the reversible seat member. Fig. 6 represents an operative assembly of the valve in filling apparatus.

Referring first to Fig. (3, the apparatus may be described generally. as comprising a reservoir 1 in the bottom of which are positioned dependent discharge tubes 2 communicating with the interior of the reservoir Referring now more specifically to the filler tube and valve construction as illustrated in Figs. 1 to 5, a guide ring 5 is positioned in an appropriate opening in the bottom wall of the reservoir, preferably having a flared portion fi extending over the reservoir wall, and secured in liquid tight attachment preferably by means of a collar 7 threaded on the guide ring in'abutment with the underside of the reservoir wall.

Supported within the guide ring 5, and in liquid tight sliding engagement therewith, is a tube 8 extending a substantial distance below the guide ring. The lower portion 9 of the tube 8 is of reduced outer diameter terminating upwardly in a shoulder 10. overlying the portion 9 of the tube 8 is a sleeve 11 in liquid tight slidable relation thereto and extending below the end of the tube. A yielding annular bottle closure 14:, preferably rubber, removablysurrounds the lower portion of the sleeve 11. and abuts a collar 12, fixed on the mid-portion of the sleeve 11. A bell member 13, supported on the collar 12, forms a canopy about the lower end of the sleeve 11 to prevent the lateral spray and loss of milk escaping ins 18 on its lower edges proportioned to fit the tapered mouth 19 of the guide ring 6, and thereby maintain the vent tube in cen tral position.

The lower end of the vent tube 15 carries an annular valve member 20 projecting outwardly of the sleeve 11 and of suflicient diameter to efiiect a closure of the lower terminal opening of the sleeve when in abutment with the sleeve end. Closure of the sleeve end opening or discharge orifice is normally maintained by a coiled spring 21 confined at its lower end by the sleeve collar 12 and the upper wall of the bell 13 and at its upper end by the collar 7. The spring tends to force the sleeve 11 into el'igageinent with the valve 20, and thereby draw down the vent tube 15 to the limit of engagement between the clip l6 and the guide ring 6, in which position the valve orifice is closed.

The upper surface of the valve 20 is preferably conical, the engaging end of the sleeve 11 being suitably shaped to form a seat therefor. The lower surface of the valve also may be tapered to facilitate the flow of passing liquid, and is preferably provided with an annular recess 21 about the terminal opening of the vent tube to prevent the premature back flow through the vent tube of liquid flowing over the valve,-and preventing the consequent interference with the discharge through the vent tube of the air being displaced from the bottle by the inflowing liquid. v

The upper end of the sleeve 11 also is shaped suitably to form a seat for the valve 20, and in case of injury to the opera tive lower end, the clip 16 may be removed from the vent tube, the latter withdrawn downwardly, and the sleeve 11 with its supported parts removed from the tube 8. By simply reversing the positions of the bell 13 and closure 14, the sleeve 11 may be reversably assembled on the tube 8-, provi l ing thereby a new seat for the valve.

Positioned on the vent tube 1-5 adj'z'lcent the valve member 20', are aseries of lined radial arms or vanes 22 extending proximately to the lower end'of the tube 8 and to the inner surface of the sleeve 11, the vanes "22 serving to assure the positive openingof the valve 20 and also to maintain the latter in central position relative to its sea-t.

lVh'en the parts are in normal position elfecting a closure the valve, the upper end of the sleeve 11 is spaced from the shoulder 10. Upon the lifting 'ei'igagement of a bottle with the closure riirg M, the sleeve 11 is lifted until it abuts the shoulder 10, and with the further rise of "the bottle the tube 8 is also carried upward through the guide ring 6. The lesser amount of friction between the sleeve 11 and the 'tu'be portion 9 than between the tube 8 and the guide ring 6, due to the smaller hoarii-ig area, assures the closing of the space be tween the end of the sleeve 11 and the shoulder 10 before the tube 8 is lifted. The relative movement of the sleeve in closing this space determines the extent of the opening of the discharge orifice. The further lift of the mechanism carries upward the clip 16 and maintains the vent tube and valve supported thereon in constant relation to the discharge tube. It will here be apparent that a uniform filling flow of liquid may be obtained Without variation due to slightly varying heights of the bottles.

If the valve 20 tends to adhere to its seat and rise with the sleeve 11, the vanes 22 immediately are engaged by the end of telescoping portions 9 of the tube 8, and with the initial movement of the sleeve 11 the valve is forced from its seat, thus assuring a positively and fully opened orifice during the filling operation.

It will now be apparent that I have provided a simple durable construction for the effective accomplishment of the purposes and objects set forth.
