Claim 1
Independent Claim
191 words
In a high speed vacuum syruper for containers having a bowl carrying filling fluid, a plurality of filling valves mounted on the bottom of said bowl, each filling valve having a valve element that rotates about a vertical axis, means for rotating said bowl and filling valves about a common vertical axis, means for moving a container into and out of engagement with each filling valve, and a control means for manipulating each filling valve in a repeating sequence through closed, vacuum, fill and vent positions, the improvement wherein said control means comprises: a pair of horizontally displaced upper and lower cam followers connected to each valve element, the upper cam follower of each pair being rotatable in a common horizontal first path, the lower cam follower of each pair being rotatable in a common horizontal second path displaced from said first path; and a control camming means comprising a pair of horizontally displaced upper and lower cam tracks, said upper cam track being engagable by said upper cam followers and said lower cam track being engagable with said lower cam followers as said bowl rotates about the common vertical axis.

In a high speed vacuum syruper for containers having a bowl carrying filling fluid, a plurality of filling valves mounted on the bottom of said bowl, each filling valve having a valve element that rotates about a vertical axis, means for rotating said bowl and filling valves about a common vertical axis, means for moving a container into and out of engagement with each filling valve, and a control means for manipulating each filling valve in a repeating sequence through closed, vacuum, fill and vent positions, the improvement wherein said control means comprises: a pair of horizontally displaced upper and lower cam followers connected to each valve element, the upper cam follower of each pair being rotatable in a common horizontal first path, the lower cam follower of each pair being rotatable in a common horizontal second path displaced from said first path; and a control camming means comprising a pair of horizontally displaced upper and lower cam tracks, said upper cam track being engagable by said upper cam followers and said lower cam track being engagable with said lower cam followers as said bowl rotates about the common vertical axis.
Claim 3
Dependent Claim
32 words
The high speed vacuum syruper of claim 1 and further comprising a switching cam for initiating a sequence of operating each valve element but only if a container is present for filling.
Claim 4
Dependent Claim
48 words
The high speed vacuum syruper of claim 2, said switching cam being located in the horizontal path of one cam follower of each pair and cooperatively active therewith to selectively rotate the valve elements into one of two positions as the one cam follower engages said switching cam.
Claim 5
Dependent Claim
68 words
The high speed vacuum syruper of claims 1, 2, or 3 wherein each valve element is centrally pivoted upon a valve seat, each valve element having a stem that extends upwardly out of the bowl; means journaling each valve stem from said bowl; and a crank arm secured to each valve stem, a pair of horizontally displaced upper and lower cam followers being mounted to each crank arm.
