567,628. Making bread. ALLEN, E. Aug. 26, 1943, No. 13933. [Class 28 (i)] A dough piece j, for example, for a cottage loaf &c., is notched by rows of serrated bars u and v, reciprocating vertically, while the dough is traversed along the rows and given a rotation so that in effect the dough is rolled against the bars, but as alternative bars move up and down, one bar counteracts the displacement push of the other. Each piece of dough is placed on one of a number of rotary supports i traversed by endless conveyer chains towards, along and away from the row of notchers u and v. A fixed rack n and a pinion imparts rotation to each support i when moving along the row. To prevent the dough from being pushed away, the conveyer can be set at a suitable inclination by screw jacks h which causes the table to pivot about f. A hand wheel z moves an abutment plate w towards or from the dough so that the depth of the notches made by the bars u and v is thereby adjustable. The notching bars move in grooves in this plate w, being reciprocated by cranks r. The notcher bars may be arranged inclined to form inclined notches.
