Abstract: A self-aligning quick connect coupling is disclosed for coupling two rods together having large diameter end portions with end surfaces in the form of spherical sectors. The coupling is formed in two halves threaded together and provides ample clearance for allowing the rods to be coupled together even though not axially aligned. The coupling halves are slotted to permit easy removal of the coupling halves from the rods when being uncoupled.

Abstract: A volume adjustment device for a filler is disclosed which simultaneously permits rough adjustment of a plurality of pistons within product cylinder and also permits fine volumetric tuning of each piston for precisely measuring predetermined volume of flowable product being discharged into containers or the like thus providing more accurate fill volumes and also minimizing fill volume differences between stations.

Abstract: A filler spool valve is disclosed having an open ended housing with an elongated cylindrical passage therethrough. A valve core having a plurality of evenly spaced arcuate and inline passages is reciprocated by a pneumatic cylinder connected thereto by a quick connect coupling to alternately cause a flowable product to flow along generally C-shaped passages, and thereafter linear passages, in the spool valve in response to reciprocation of the valve core. The valve core is easily removed from its housing for cleaning by opening a quick release coupling and manually pulling the core from the cylindrical housing.
