Abstract
The specification and drawings disclose an apparatus for dispensing a fine dispersion of grease into the interior of baking pans. The disclosed apparatus comprises a continuous screen belt which moves above a conveyor on which the pans are traveling. Above one run of the belt is an air chamber from which high-velocity, short-duration air jets are directed downwardly through the screen. The air jets are laid out in a pattern generally corresponding to the shape of the interior of the baking pans. Additionally, a roller and hopper assembly is provided to apply a coating of grease to the mesh so that the air passing therethrough causes the grease to be dispersed into the pans.
Claims5
Apparatus for applying to a surface a relatively uniform layer or film of a relatively viscous fluid in a predetermined pattern, said apparatus comprising:
- a sheet of foraminous material having first and second opposed sides and an area greater than said predetermined pattern;
- first means for supporting said sheet with its first said facing and closely adjacent said surface;
- second means for saturating said sheet with said fluid;
- and,
- air discharge means mounted closely adjacent said second side of said sheet, said air discharge means including:
- a first plate member extending generally parallel to said sheet and having a multiplicity of small, closely-spaced openings extending therethrough and laid out in a pattern corresponding to said predetermined pattern and directed toward the second side of said sheet;
- a second plate member positioned generally parallel to and closely adjacent said first plate member on the side opposite said sheet, said second plate member having a multiplicity of relatively uniformly spaced perforations extending therethrough and directed toward said first plate member;
- air chamber means enclosing said second plate member;
- and,
- valve means for opening and closing said perforations to allow air from said air chamber means to pass through said first and second plates and discharge through said openings and through said sheet.
