Abstract
Abstract Fluid filling machine with novel control valving movable from closed to open condition when a container is in position to receive the filling fluid, the valving remaining closed if no container is present and in such event permitting bypass return flow of the filling fluid to its source. The valving is operated by a control lever which is movable from an inoperative to operative position by the container that is to be filled. The lever, in turn, in its operative position is moved to valve-open position by engagement of the lever with a cam in the path of travel of the container to initiate filling thereof and is subsequently movable to close the valve at completion of fill, the latter movement being effected either by sensing means responsive to level of fill in the container or a further cam in the event of failure of the sensing means. In intermediate stages of the fill, the lever can be manipulated to a controlled extent by additional cam means to control rate of flow during fill if desired. The valving is applicable to rotary or linear filling machines. Valving arrangements suitable for gravity and pressure filling are disclosed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
222 words
In a container filling machine, conveyor means for moving containers successively in a rotary path of travel for filling from a fill source, common means for delivering fill material from said source to each such container during its movement in said rotary path, including a plurality of spout means insertable respectively into successive containers entering said path, said spout means each being individually communicable with said delivery means, means for positioning containers successively while moving in said rotary path for insertion into each successively of one of said spout means, independent rotary valves between said fill material delivery means and each of said spout means, valve rotating means comprising stationary means in said rotary path and an independent valve rotating member for each valve movable with its valvE in said rotary path, each valve rotating member being separately movable and normally lying in a nonengageable inoperative condition relative to said stationary means, means requiring presence of a container in said rotary path with an inserted spout means to move said valve rotating member into operative engageable condition with said stationary means for then rotating said valve to shift said valve from closed condition to open condition to permit flow of fill material into said container, and additional means to rotate the valve to closed condition upon completion of fill of said container.
Claim 2
Dependent Claim
222 words
In a container filling machine, conveyor means for moving containers successively in a rotary path of travel for filling from a fill source, common means for delivering fill material from said source to each such container during its movement in said rotary path, including a plurality of spout means insertable respectively into successive containers entering said path, said spout means each being individually communicable with said delivery means, means for positioning containers successively while moving in said rotary path for insertion into each successively of one of said spout means, independent rotary valves between said fill material delivery means and each of said spout means, valve rotating means comprising stationary means in said rotary path and an independent valve rotating member for each valve movable with its valvE in said rotary path, each valve rotating member being separately movable and normally lying in a nonengageable inoperative condition relative to said stationary means, means requiring presence of a container in said rotary path with an inserted spout means to move said valve rotating member into operative engageable condition with said stationary means for then rotating said valve to shift said valve from closed condition to open condition to permit flow of fill material into said container, and additional means to rotate the valve to closed condition upon completion of fill of said container.
Claim 3
Dependent Claim
135 words
In a container filling machine according to claim 1, each said valve rotating member comprising a lever freely pivoted to a part of said rotary valve, said lever normally tending to lie in an oblique position relative to horizontal so that its shorter arm is nonengageable by said stationary means and its longer arm is nonengageable by said additional means, the said means requiring presence of a container in said path with an inserted spout means serving to turn said lever from its said oblique position to a position wherein its shorter and longer arms are respectively in engageable conditions with respect to said stationary means and said additional means in seratium during travel in said rotary path of each said lever and the said part of said valve to which it is freely pivoted.
Claim 4
Dependent Claim
79 words
In a container filling machine according to claim 2, wherein said stationary means and said additional means respectively comprise separate cam means, each independently and adjustably positionable as to their respective extents of projection into the rotary path of travel of the respective shorter and longer arms of each said lever, the extent respectively of such projections controlling respectively the amount of closing and opening rotation imparted to the respective valve to whose part said such lever is pivoted.
Claim 5
Dependent Claim
45 words
In a container filling machine according to claim 1, return flow means for fill material to its source and bypass in said valve means for interconnecting said means for delivering fill material and said return flow means when said valve is in its closed condition.
Claim 6
Dependent Claim
39 words
In a container filling machine according to claim 1, fill level detecting means and means controlled by said detecting means to rotate the valve to valve closing condition upon achievement of a selected extent of fill of the container.
Claim 7
Dependent Claim
21 words
In a container filling machine according to claim 5, overflow means for the container with which said detecting means is connected.
Claim 8
Dependent Claim
57 words
In a container filling machine according to claim 2, said part of said rotary valve including a body portion and said means serving to pivot said lever includes a slide member movable on said body portion by movement of a container to position to be filled to engage said lever and move it from its oblique position.
Claim 9
Dependent Claim
65 words
In a container filling machine according to claim 1, said rotary valve including a passageway having a part movable on rotation of said valve from closed condition to open condition with respect to said delivering means and vice versa, and said spout means communicating with said passageway for introduction into a container to be filled of fill material in the open condition of said valve.
