Lying:Withinnthenlower portion of the valveeasing 17 is a fixed sleeve 25'1having a top Wall 26 carrying a Central guide 27 for the depending stem 28 of a ball valve 29 that t v normally oecupiesthevalveseatlS end shuts Fig. 2 is a similar' view shoivingthe'parts ofil the flow of liquid.` Opposite sides of the sleeve *arev Yformed With openings 30 that register With` the openings 20, 21and 23, Yand the Walls of the sleeve between said opend when the latter is in its raised position (Fig. p

2). The short arm of this lever carries a counterweight 35, andthefree end of its long arm normally engages a shoulder .36 formed on a trigger member 37 that is pivoted at 38 between a pair of upstanding lugs 39` carried'by the movable sleeve 22; said trigger having an inwardly extending arm 40 from the free endof which is suspended a float l1 movable in and guided by the lower portion of the fixed sleeve member 25.

YThe normal position of the parts is as shown in Fig. l. When a bottle is raised into engagement with the lower end `of the movable sleeve 22'a11d the latter is raised to the extent permitted by the adjustable stop nut 24, the valve 29 is raised, as shown in Fig. 2, and the liquid flows into the bottle, the air in the latter finding a ready vent around the lower end of the valve casing and through the openings 23 and 20. rIhe stop 24, by adjustment up .or down, variesi the extent of opening of the valve and consequently'the rapidity of the flow. At this time the weight of the float il and arm 40 of the trigger is slightly but suiiiciently in excess of the'downward thrust of the open valve to maintain the parts in the relative positions shown in Fig. 2. `When the bottle has been lled to the required height, the raising of the ioat by the liquid in the bottle tilts the trigger, moving the supporting shoulder 36 thereof away. from the free end of the valve-supporting lever 34, whereupon the parts instantly assume the relative positions shown in Fig. 3 wherein the valve 29 is closed, and the flow of liquid to the bottle is shut off. As the bottle is withdrawn the movable sleeve 22 descends, lowering the i opening parts in a purely mechanical bottlellingvalve mechanism is a new result so far as we are aware,'andconstitutes an important feature of our present invention. ItV will also be observed that `the weight or thrust of the valve, when open, is applied through the lever 34 to the trigger 37 at a point Qn the opposite side ofthe pivotof the latter from the oat, thus tending to raise the latter. The fioat 1s, of course, heavy enough to resist this tendency (eX- Vcept when raised by the liquid in the bottle) but this arrangement makes practicable the use of a comparatively small iioat, and renders the mechanism very sensitive and uniform in its action, resulting in a uniform filling of the bottles served thereby.

While we have shown and described a particular form of mechanism for accomplishing the stated objects of the invention, it will bemanifest to those skilled in the art that the same may be modified in detail within the operative principle of the invention and without sacrificing any of the advantages secured thereby. We therefore do not limit the invention to the exact mechanism shown-and described, but include all equivalents thereof which come within the purview and spirit of the appended claims.

We claim: i l. In a bottle-filling device of the character described, the combination of a valve casing having a valve seat, a valve movable towardand from said seat, a Vvertically movacter described, the combination of a valveV easing having a valve seat, a valve movable toward and fromsaid seat, a vertically mov-` able sleeve on said valve casing adapted to be lifted by a bottle when brought into filling position, and a `float-controlled valveopening mechanism carried by said sleeve, said mechanism including normally engaged elements which operate to open said valve when said sleeve is raised, disengage under the action of the float and permit the valve to close when the liquid in the bottle reaches a predetermined height and automatically rengage eachother when said Vsleeve descends.
