Abstract
Abstract Known pumping supply system consists of supply vat having in its bottom section twin lateral delivery screws extending to a discharge outlet in an end wall and which are rotated in opposite directions. The discharge outlet is flow connected to the intake of a delivery pump. The present improvement adds thereto a pair of oppositely rotated, laterally extending and transversely spaced, flow-directing feeders mounted in the vat relatively closely above the delivery screws. Each feeder has a driven shaft on which is mounted along diametrically opposite sides thereof a pair of sets of a plurality of substantially radially extending and rather closely spaced paddles. These sets of paddles of one feeder shaft are rotated by its shaft out of radial angular phase with those of the other feeder shaft. These rotating feeders cooperatively force the viscous material down into the lateral trough-shaped receiving throat between the delivery screws. This improvement also includes a delivery and return conduit which is flow connected between the discharge opening of the delivery pump and an upper portion of the vat. Between the delivery pump and a terminal portion of this return conduit there is flow connected to the latter one or more supply branch lines to supply the pumped material to one or more use receiving stations. Each branch line may have connected therein a flow rate controlling pump.

Claim 5
Dependent Claim
334 words
A pumping supply system for delivering at ambient temperature highly viscous and butter-like paste material at a relatively uniform rate of flow and substantially free of air voids comprising, in combination; 1. a supply vat defining a supply chamber having a lateral bottom section provided at one end with a laterally directed outlet; 2. delivery pumping means having its intake flow connected to the vat outlet; 3. a pair of oppositely rotated and laterally extending driven delivery screws in the bottom section of said vat chamber extending in closely spaced general parallelism to said vat outlet which define therebetween a lateral trough-shaped receiving throat; 4. a pair of oppositely rotated, laterally extending and transversely spaced, flow-directing feeders mounted in said vat chamber bottom section relatively closely above said delivery screws, each comprising a driven lateral shaft carrying along its length and fixed thereto a plurality of substantially radially extending paddles; and 5. means to drive said feeder shafts in opposite certain directions that cause said paddles on each of said feeder shafts to swing forward toward the other feeder shaft and downward through the transverse space intervening said feeders cooperatively to cause the latter to force the paste material down into the trough-shaped receiving throat between said screws; 6. said delivery pumping means having its discharge opening connected to delivery conduit means leading to use receiving means which demands less than the maximum delivery rate capacity of the delivery pumping means and said delivery conduit means, the latter having a terminal section defining a flow path back to said supply vat for return to the latter of the excess above the demand of the use receiving means; and 7. said use receiving means comprising a plurality of separate use receiving stations with a plurality of supply branch lines connected to said delivery conduit means between the delivery pumping means and the terminal return section with each branch line leading to one of said stations, each branch line including a separate flow rate controllinG pump.
