BOTTLE-FILLE?, VALVE.

Application sied July 27,1923- To all whom t may concern:

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

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

rl`he usual construction of such apparatus includes a reservoir from which depends one or more discharge tubes, cach 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 vent tube, ordinarily provided for the escape of air from the bottle being filled, is adjustably controllable to vary the rate of How of the escaping air, and thereby vary the rate of flow of the iniiowing milk or cream suitably to the variable conditions or temperature and consistency of the liquid so that the formation of froth may be minimized.

Another object is to provide means associated with the vent tube for its maintenance in centralized position within the discharge tube so that the valve member carried on the lower end of the vent tube is assured of being opened with a uniform orifice and is tightly seated when closed.

A further object is to provide means for rendering inoperative, when desirable, certain of the valves in the filling apparatus, and permit their being raised by Contact with the bottles, as in normal operation, but without discharging milk into the bottles.

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.

1n 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. 8 is a similar view including the valve cap for rendering the Serial No. 654,087.

valve inoperative. Fig. 4C is a sectional plan view taken on the plane of the line 1-1 in Fig. 3. Figs. 5 and 6 represent respectively the vent tube controlling device and the removable cap for rendering the valve inoperative.

Referring to the drawings, the numeral 1 indicates a fragmentary portion of the bottom wall of the reservoir in a bottle filling apparatus. A guide ring 2 is positioned in an opening through the bottom wall 1, and is preferably secured in position by a flared portion 3 projecting over the reservoir wall and a collar a threaded on the guide ring in abutment with the underside of the wall.

Slidably supported within the guide ring 2 is a discharge tube 5 extending a substantial distance below the guide ring. A yielding annular bottle closure 6, preferably rubber, is removably mounted on the lower end of the tube 5 and abu'ts a collar 7 fixed on the tube. A bell member 8, supported on the collar 7, forms a canopy about the lower end of the discharge tube to prevent lateral spray from an imperfect seal between a damaged bottle and the closure 6.

Positioned centrally within and in spaced relation to the discharge tube 5 is a vent tube 9 extending upwardly into the reservoir to a height above the level of the contained milk or other liquid. The vent tube 9 is supported by a removable spring clip 10 embracing the tube below a collar 11 fixed upon the tube and resting upon the clip. The clip 10 is provided with tapered extensions 12 on its lower edges which engage with self-centering effect the tapered mouth 13 of the guide ring 3, and thereby maintain the vent tube in central position when the valve is closed. Further extensions 14: are also provided on the clip 10 which are proportioned to enter the upper end 'of the discharge tube 5, when the latter is raised in the operation of the valve, and which serve to retain the vent tube in central position after the clip has been raised from its seat within the tapered mouth of the guide ring. Similar extensions may be formed on the upper edges of the clip so that the latter is reversible in position.

The lower end of the vent tube 9 carries an annular valve member 15 projecting outwardly of the discharge tube 5` and of sufiicient diameter to effect a closure of the lower terminal opening of the discharge tube g Leser/se When in abutment with the tube end.
