Abstract
Abstract A mixer type device has a container for materials built in two parts, the upper part being rigid and mounted on a frame and the lower part being flexible. A stiff disc at the center of the flexible part has a wobbler attached to it driven by a motor mounted on the frame below the container. For discharging material from the container a section of the flexible lower part is releasably connected to the disc so that when disconnected the material will be discharged downwardly into a delivery chute. After discharge the section can be reconnected to the disc and the container then made ready to receive a new load of material which is put in at the top.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
An agitating device for aggregate type materials comprising a frame, a container constructed in two sections, a first of said sections being rigid and mounted on the frame, said rigid section having a feed opening at the upper side and a perimetrical rim at the lower side, a second of said sections being of flexible material having a rim anchored to the perimetrical rim of the first section and forming a flexible bottom for the container, said second section having a central rigid disc at the lowermost location, a wobble drive connected to said rigid disc, and discharge port means at the lower portion of said second section having a closed position during operation of said wobble drive and an open position when operation of the wobble drive is discontinueD whereby to discharge the contents of said container.
Claim 2
Dependent Claim
138 words
An agitating device for aggregate type materials comprising a frame, a container constructed in two sections, a first of said sections being rigid and mounted on the frame, said rigid section having a feed opening at the upper side and a perimetrical rim at the lower side, a second of said sections being of flexible material having a rim anchored to the perimetrical rim of the first section and forming a flexible bottom for the container, said second section having a central rigid disc at the lowermost location, a wobble drive connected to said rigid disc, and discharge port means at the lower portion of said second section having a closed position during operation of said wobble drive and an open position when operation of the wobble drive is discontinueD whereby to discharge the contents of said container.
Claim 3
Dependent Claim
27 words
An agitating device as in claim 1 wherein there is a motor on the frame and a drive shaft on the motor connected to said wobble drive.
Claim 4
Dependent Claim
34 words
An agitating device as in claim 1 wherein there is a discharge chute on the frame having a loading end beneath said discharge port means and an unloading end remote from said loading end.
Claim 5
Dependent Claim
85 words
An agitating device as in claim 1 wherein said discharge port means comprises a relatively stiff segment at the perimeter of said disc, releasable securing handles in operable engagement with said disc and said segment each having respective locked and unlocked position, and edge portion of said second section having a shape conforming to said segment and adapted to be releasable held in position closing said discharge port means and adapted to be released to open said discharge port means when said segment is released.
Claim 6
Dependent Claim
22 words
An agitating device as in claim 4 wherein the relatively stiff segment is attached to the flexible material of said second section.
Claim 7
Dependent Claim
37 words
An agitating device as in claim 1 wherein said discharge port means comprises at least one aperture through said disc and a closure rotatably mounted on said disc having open and closed positions relative to said aperture.
Claim 8
Dependent Claim
41 words
An agitating device as in claim 1 wherein said discharge port means comprises a plurality of apertures through said disc at circumferentially spaced locations and a closure rotatably mounted on an axis concentric with respect to the center of said disc.
Claim 9
Dependent Claim
26 words
An agitating device as in claim 7 wherein there is a discharge chute having an annular receiving portion at the upper end located beneath said apertures.
Claim 10
Dependent Claim
64 words
An agitating device as in claim 1 wherein said discharge port means comprises a plurality of apertures extending through said disc and circumferentially spaced around the center of said disc, and a closure extending over said apertures at the inner side of said disc, an outwardly extending stem on said closure and a central bore through said disc having said stem reciprocatably located therein.
Claim 11
Dependent Claim
31 words
