To all whom it may concern:

Be it known that I, CHARLES S. ADAMS, a citizen of the United States, residing in the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Valves for Filling Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is directed to the provision of an improved form of valve for use in filling bottles with a liquid from a suitable receptacle. The invention is of special utility in valves for use in filling milk bottles, a plurality of the valves being located in the bottom of a receptacle for the milk in positions to coact with the open necks of a plurality of bottles supported in a suitable crate which is raised vertically to carry the necks of the bottles into enga ement with the valves.

alves for this use have heretofore been conmionly constructed consisting of two telescoping tubular members and a spring coiled about them to hold them normally extended, the lower end of the lower tubular member being adapted to be engaged by the neck of a milk bottle and raised thereby against the tension of the spring. In combination with these parts, an air tube is employed extending through the tubular members and provided with an enlargement at its lower end which coacts with the lower end of the lower tubular member to open and close the passage for the flow of the milk into a bottle. In valves of this char acter, various means have heretofore been devised for supporting the air tube. This tube should not be supported rigidly as sometimes its lower end is engaged by the neck of a bottle and the tube should therefore have a slight capacity for upward movement to guard against breaking the neck of the bottle. Also, the air tube should be supported in such a way that its support, or a portion thereof, may be readily withdrawn to permit the tube to be passed downwardly through the telescoping tubular members, as in this way'the parts of, the valve may be quickly detached one from anether-for-cleanin l r With view, it has been pro- Serial No. 193F201}.

posed heretofore to mount a supporting device detachably upon the upper end of the tubular members arranged to coact with a shoulder on the air tube to support the latter and provided with a side opening whereby it may be moved laterally with respect to the air tube and thus become detached from the latter. Such a detachable support for the air tube I have found to be open to very serious objection in that it may, and in use frequently does, become unseated, thus requiring either that the milk be drawn off from the reservoir to permit of reseating the support or that the operator reach into the milk and position the support. It will be understood that when the crate of bottles is raised mechanically 1nto coaction with the lower ends of the valves and the valves operated to open them, the parts of the valves are subjected to a severe jar which is frequently sufiicient to cause the unseating of a relatively light supporting member not securely fastened in position.

I have found that this objectionable characteristic of such valves as heretofore made may be avoided, and for this purpose have devised an improved construction wherein the parts are so constructed and arranged as to eliminate all danger of disarrangement of the parts during the operation of the apparatus. The improvement consists primarily in forming the major portion of the support, that is, the portion provided with an opening through which the milk flows from the reservoir into the valve, integral with one of the tubular members of the valve. This portion of the support for the air tube has a ring at its upper end provided with a central opening of a size sulficient to permit the upper portion of the air tube to pass therethrough. This ring constitutes the support for another ring having a central opening of less size, the central opening in this second ring being only of the size of the air tube proper so that the shoulder on the air tube will engage the second ring and be supported thereby. This second ring is open on one side so that it may be withdrawn from the air tube to permit the latter to move downwardly and thus be'ldisengaged from the other-parts-of the va ve.

. I have-illustrated the preferred embodimit it to be moved upwardly'by a bottle if ment of my invention in the accompanying drawings, in which Figure 1 is an elevation Of .the valve; Fig. '2is a central lon .ltudinal 'sectionthereof; Fig. .3 is a view o the upper membersof the valve with the support-I ing ring removed; and Fig. 4 is a transverse section online of Fig. 1.

Referring to these drawings,.the valve comprises two vertically dis osed concen-' tric telescoping tubular mem ers 5v and 6..

The tubular member 5 constitutes the frame memberof the valve and is provided with threads 7 adapted to coact with threads in an opening in the bottom of thereceptacle for the milk to secure the valve in position upon the receptacle. Below these threads is a flange Sadapted to'engagel the bottom of the receptacle and a polygonal .portion- 9 to which awrench may be applied to secure the framemember inposition or withdraw it therefrom. The tubular member 6 fits within the tubular member 5 and a spring 10 encircles thesefparts, this spring acting upon a fiangejll on the member 6 to force thelatter downwardly. ()n the lower end of the. tubular member 6 is a gasket 12 of J rubber or other suitable soft materiaL. The

air tube is. shown'at-13. On its lowerend itiis provided with an enlargement 14 in cluding a washer 15 Which- 1s. adapted to coact with the. lower end of the tubular member 6 to close and open the passage through the latter. The air tube has a 'cen m1 passage therethrough opening upon the sides of the conical enlargement. 14' and its functionis to permit the escape of air from a bottle upwardly. through the air tube as the milk flows I downwardly through the member 6'into thebottle. Q I

. The air tube 13 is so supported as to per the neck of the bottle engages the lower end of the tube. Also, itisxso supported as to permit of its detachment from the supporting means inwhich case the air tube maybe lowered through the tubular members 5 and q 6 and disengaged therefrom, whereupon; the parts 5, 6 and 10'may bedisengaged. In this vvto way, all of the parts of the valvemay be. quickly detachedfor cleaning.

Thefineans'for supporting the air tube 13 consists of parts extending upwardly from the tubular memberv 5'and formed integral therewith,- and. a detachablesupporting device seatedlxupon these parts. In the drawings, itwill besseen that thetubular member 5zwhich is adapted to-besecuredto the bottom of the reservoi'rfis extended up- .Wardly by struts or standards 16 which are formed integral with the tubular member 5.

Atthe vupper'end of these struts or standards I 16-is a ring 17 also formed as an integral part of. theztubu'lar member 5. -'Itwill be noted, particularly from Fig. 1, that below this 17 openings are provided between 3 the struts 16 leadingto the interior of the tubular member 5, and it is through these openings-that" the milk passes from the reservoir into the valve. The ring 17. has a central opening therethrough and theair tube 13 passes through this opening, but the opening is of substantially larger diameter than the diameter of the tube. This ring 17' formsa seat for a second ring .18. This ring 18 has a depending flange 19 such that when it is seated upon the ring 17, the flange 19 extends down along the periphery of thering 17 asubstantial amount and thus holds the ring 18 upon its seat upon the ring 17.so :securely as-to quite effectually guard against displacement of the detachable ring 18 by jarring of the parts. The ring 18 has a central opening therethrough which is of less size than the opening 1n the ring 17 it is large enough to receive the a1r tube 13 but is of less size than the enlargement or shoulderon the air tube. Also this ring 18 is" open on one side, that is, it 1s slotted to form a passage for the air tube 13 through the side of the ring to the central opening thereof. The shoulder upon the air tube is preferably provided by securing a supporting tube 20 to the upper end of the tube 13,' thelower end of this tube QO forming the shoulder and the tube extending'the passage for the air upwardly above the surface of the" liquid in the reservoir.

Fig. 1 shows the parts of the'valve in the positions which they normally occupy. When in this position, the parts are supportedwith such a' degree of rigidity that all danger of accidental detachment iseliminated. This is due primarily to the forma tion of the struts l6 and ring'17 as integral parts of the upper'tubular member 5. his also due to thefact that the ring 18, by rea} son of its flange 19, seats itself upon. the ring 17 very securely. If it be desired to disassemble theivalve, theair tube-'13 andthe member 6 are moved upwardly relatively to the member 5 against the tension of'spring 1 0 a slight amount, whereupon the ring 18 y a is raised from its seat and withdrawn I lateral movement from the air tubel3, as

shown in Fig. 3. The air tube may then be lowered, theshould'er at the lower end of the larger tube 20 passing through 'the ring 'l'i. and the tubularmembers 5 and 6.
