Abstract
Abstract A mixing-metering device includes a pair of hoppers for supplying dissimilar free flowing granule materials through a pair of discharge openings to a collecting chamber. The collecting chamber includes two pairs of spaced filling openings with metering means arranged between the discharge and filling openings for simultaneously receiving metered amounts of the dissimilar materials from the discharge openings while simultaneously discharging metered amounts of the materials into the filling openings.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
A mixing-metering device for obtaining a homogeneous mixture of a plurality of materials comprising a first hopper for supplying a first free flowing granular material, a second hopper for supplying a second dissimilar free flowing granular material, a collecting chamber, said chamber having a first pair of spaced material filling openings, said first hopper having a material discharge opening disposed between said first pair of material filling openings, said chamber further having a second pair of spaced material filling openings, said second hopper having a material discharge opening disposed between said second pair of spaced material filling openings, and metering means between said discharge openings and said filling openings for simultaneously receiving metered amounts of the dissimilar materials from said discharge openings while discharging metered amounts of the dissimilar materials into said filling openings; in combination therewith, an injection molding machine, a mixture hopper communicating with said injection molding machine, and means for transporting the mixed materials from said collecting chamber to said mixture hopper.
Claim 2
Dependent Claim
165 words
A mixing-metering device for obtaining a homogeneous mixture of a plurality of materials comprising a first hopper for supplying a first free flowing granular material, a second hopper for supplying a second dissimilar free flowing granular material, a collecting chamber, said chamber having a first pair of spaced material filling openings, said first hopper having a material discharge opening disposed between said first pair of material filling openings, said chamber further having a second pair of spaced material filling openings, said second hopper having a material discharge opening disposed between said second pair of spaced material filling openings, and metering means between said discharge openings and said filling openings for simultaneously receiving metered amounts of the dissimilar materials from said discharge openings while discharging metered amounts of the dissimilar materials into said filling openings; in combination therewith, an injection molding machine, a mixture hopper communicating with said injection molding machine, and means for transporting the mixed materials from said collecting chamber to said mixture hopper.
Claim 3
Dependent Claim
36 words
A device as set forth in claim 1 wherein said metering means includes a slide plate having metering pockets for selective communication with said discharge and filling openings, and drive means for reciprocating said slide plate.
Claim 4
Dependent Claim
34 words
A device as set forth in claim 2 wherein said drive means is connected to said slide plate for causing uniform acceleration-deceleration-dwell on each stroke thereof to facilitate the accurate filling of said pockets.
Claim 5
Dependent Claim
70 words
A device as set forth in claim 3 wherein said drive means is connected to said slide plate in such a manner as to provide an overstroke of said pockets with respect to said discharge and filling openings. 5. A device as set forth in claim 4 wherein said drive means includes a rotatable disk, and a crank arm eccentrically connected to said disk and connected to said slide plate.
Claim 6
Dependent Claim
48 words
A device as set forth in claim 5 wherein said slide plate includes two pairs of said metering pockets, a connective channel being provided between the pockets of at least one of said pairs and being of sufficient size to accommodate the granular material and prevent shearing thereof.
Claim 7
Dependent Claim
47 words
A device as set forth in claim 6 wherein each discharge opening is disposed between its respective openings a distance of about one-half the distance between said filling openings, and the distance between its pair of metering pockets being about one-half the distance between said filling openings.
Claim 8
Dependent Claim
18 words
A device as set forth in claim 7 including means for adjusting the capacity of said metering pockets.
Claim 9
Dependent Claim
51 words
A device as set forth in claim 2 wherein said slide plate includes two pairs of said metering pockets, a connective channel being provided between the pockets of at least one of said pairs of metering pockets and being of sufficient size to accommodate the granular material and prevent shearing thereof.
Claim 10
Dependent Claim
47 words
A device as set forth in claim 9 wherein each discharge opening is disposed between its respective openings a distance of about one-half the distance between said filling openings, and the distances between its pair of metering pockets being about one-half the distance between said filling openings.
Claim 11
Dependent Claim
36 words
A device as set forth in claim 2 including regrind means for grinding waste material from said injection molding machine, and said regrind means communicating with said means for transporting the mixed materials from said chamber.
Claim 12
Dependent Claim
22 words
A device as set forth in claim 12 wherein said first hopper and said second hopper comprise compartMents in a single hopper.
Claim 13
Dependent Claim
25 words
A device as set forth in claim 12 including level indicating switch means in said material hopper for controlling the actuation of said slide plate.
Claim 14
Dependent Claim
141 words
A device as set forth in claim 13 wherein drive means is connected to said slide plate for causing uniform acceleration-deceleration dwell on each stroke thereof to facilitate the accurate filling of said pockets and to provide an overstroke of said pockets with respect to said filling and discharge openings, said drive means including a rotatable disk, a crank arm eccentrically connected to said disk and connected to said sliding plate, said pockets comprising two pairs of pockets for each discharge opening, a connective channel being provided between the pockets in one of the pairs and being of sufficient size to accommodate the materials therein and prevent shearing thereof, each discharge opening being located midway between its respective pair of filling openings, and the distance between each pair of pockets being about half the distance between its pair of filling openings.
Claim 15
Dependent Claim
49 words
A device as set forth in claim 14 wherein the capacity of each pocket in one of said pockets is about 10 times greater than the capacity of each pocket in the other pair of pockets, and means for varying the capacity of at least one pair of pockets.
