Abstract

Apparatus for intermittently dispensing fragile particulate material, such as sesame seeds through openings in a tube to spread material over an array of horizontally and vertically spaced rows and columns such as upper surfaces of buns in a pan. The dispensing apparatus comprises a hopper from which fragile particulate material is dispensed through a dispensing tube in which a mandrel driven by a variable speed motor is rotatably disposed. The mandrel has spaced spline teeth formed on its outer surface in dispensing sections separated by blocking collars spaced longitudinally of the mandrel such that rotation of the mandrel causes particulate material to be dispensed in parallel columns and such that intermittent rotation of the mandrel causes the columns to be divided to form rows. The major diameter of the spline teeth on the mandrel is less than the outside diameter of the blocking collars to provide an arcuate annular dispensing passage between the interval of the dispensing tube and the major diameter of the spline teeth in a range of 11/2 to 2 times the diameter of particles of material being dispensed.
