Abstract Device for spreading butter or other viscous material uniformly across full width of dough sheet on belt conveyor, comprising a base removably mounted above conveyor with elongate, centrally disposed and laterally extending delivery slot therethrough, a casing removably attachable at lower end to the base and having an inlet at upper end, a labyrinth removably supported on the base within the casing, whereby removal of casing, labyrinth and base may readily be effected to facilitate cleaning the labyrinth being formed by a plurality of horizontal plates extending the full interior lateral length of the casing and spaced vertically from each other, with two apertures through the transverse centerline of the uppermost plate spaced on opposite sides of the inlet on centers one-fourth of the length of the plate from its ends, four slots spaced one-fourth the length of the plate from each other along both front and rear edges of the next lowermost or second plate, and eight apertures through transverse centerline of third plate spaced one-eighth the length of the plate from each other to provide uniform misaligned lateral spacing of all apertures and slots in the three upper plates, and a bottom plate narrower than the casing to insure equal distribution of material along doubly reversed paths between the center and the front and rear walls of the casing and successive plates from inlet to delivery slot, and a metering plate slidably mounted on the base for selective manual adjustment horizontally relative to the delivery slot to determine the rate of delivery of material therefrom.
A spreader for viscous material, comprising a base having an elongate and laterally extending delivery slot therethrough for depositing the viscous material, a casing removably attachable at its lower end to said base and having an inlet at its upper end for receiving the viscous material under pressure, and a labyrinth disposed within said casing between said inlet and said delivery slot for directing the flow of viscous material therethrough to distribute the same to said delivery slot uniformly over its full length, wherein said labyrinth comprises a plurality of horizontal plates extending the full interior lateral length of said casing and spaced vertically from each other.

A spreader for viscous material, comprising a base having an elongate and laterally extending delivery slot therethrough for depositing the viscous material, a casing removably attachable at its lower end to said base and having an inlet at its upper end for receiving the viscous material under pressure, and a labyrinth disposed within said casing between said inlet and said delivery slot for directing the flow of viscous material therethrough to distribute the same to said delivery slot uniformly over its full length, wherein said labyrinth comprises a plurality of horizontal plates extending the full interior lateral length of said casing and spaced vertically from each other.
Claim 3
Dependent Claim
40 words
A spreader according to claim 1, wherein each said horizontal plate defines vertical pathways therepast separated by imperforate areas and the total imperforate area of each successively lower plate is less than that of the next preceding plate above it.
Claim 4
Dependent Claim
30 words
A spreader according to claim 2, wherein said vertical pathways defined by each said plate are spaced in a front-to-rear direction relative to those defined by the plates adjacent thereto.
Claim 5
Dependent Claim
25 words
A spreader according to claim 3, wherein said vertical pathways defined by the uppermost said horizontal plate are spaced laterally relative to said casing inlet.
Claim 6
Dependent Claim
37 words
A spreader according to claim 4, wherein said vertical pathways defined by the next two of said plates below said uppermost plate are successively spaced laterally relative to each other and to those of said uppermost plate.
