Abstract
Abstract An apparatus for separating pigment containing cake from a vehicle such as water is disclosed. The apparatus comprises a skimmer which includes a reservoir for containing the cake containing vehicle and a continuous conveyor belt inclined upward from a surface of the cake containing vehicle. In a preferred embodiment a plurality of upward extending walls are attached to the conveyor belt for skimming the cake from the vehicle. An inclined wall is disposed parallel to a space below the belt to slidingly engage the outward extending walls as they move therepast. A lower portion of the inclined wall is positioned over the reservoir, and an upper portion of the inclined wall extends outward from the reservoir, with the lower portion of the inclined wall perforated to allow vehicle to drain from the cake into the reservoir thus separating the cake and the vehicle. A discharge opening formed at an upper end of the inclined wall allows the separated cake to be discharged into a receptacle for collection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
An apparatus for separating pigment containing cake from a vehicle comprising: a reservoir for holding the cake containing vehicle; a continuous conveyor belt supported within the reservoir inclined upward from a surface of the cake containing vehicle; at least one outward extending wall attached the belt including a pair of opposed ends and an outer edge, said outward extending wall engaging the cake containing vehicle at a lower end of the belt; an inclined wall supported within the reservoir disposed parallel to and spaced below the belt slidingly engaging the outer edge; a discharge opening formed at an upper end of the inclined wall; a pair of opposed vertical walls affixed the inclined wall; a pair of opposed vertical resilient walls attached the opposed ends slidingly engaging the opposed vertical walls; and wherein cake is collected from the vehicle at a lower end of the belt and moved along the inclined wall by the outward extending wall and discharged through the discharge opening.
Claim 2
Independent Claim
163 words
An apparatus for separating pigment containing cake from a vehicle comprising: a reservoir for holding the cake containing vehicle; a continuous conveyor belt supported within the reservoir inclined upward from a surface of the cake containing vehicle; at least one outward extending wall attached the belt including a pair of opposed ends and an outer edge, said outward extending wall engaging the cake containing vehicle at a lower end of the belt; an inclined wall supported within the reservoir disposed parallel to and spaced below the belt slidingly engaging the outer edge; a discharge opening formed at an upper end of the inclined wall; a pair of opposed vertical walls affixed the inclined wall; a pair of opposed vertical resilient walls attached the opposed ends slidingly engaging the opposed vertical walls; and wherein cake is collected from the vehicle at a lower end of the belt and moved along the inclined wall by the outward extending wall and discharged through the discharge opening.
Claim 3
Dependent Claim
46 words
The apparatus as defined in claim 1 further comprising: an upper portion of the inclined wall deployed above the cake containing vehicle; and a plurality of apertures formed in the portion of the inclined wall deployed above the vehicle for draining vehicle back to the reservoir.
Claim 4
Dependent Claim
44 words
The apparatus as defined in claim 2 further comprising a resilient wall attached the outer edge slidingly engaging the inclined wall; and the resilient wall projecting into the apertures to provide a wiping and cleaning of the apertures as the resilient wall moves therepast.
Claim 5
Dependent Claim
24 words
The apparatus as defined in claim 1 further comprising: a pair of opposed vertical walls affixed the inclined wall slidingly abutting the opposed ends.
Claim 6
Dependent Claim
