ABSTRACT:
A bun marking machine is disclosed in which a formed heating member is brought into contact with a baked bun for marking the top of the baked bun with a distinctive pattern. The heated member in the disclosed bun marking machine is an electrically heated element supported in a detachable head. The heating element is formed into a selected shape and sheet metal bun branding patterns are attached thereto. During operation the element gets very hot and also heats the marking pattern hot enough to mark a baked bun when brought in contact therewith. Various detachable heads are provided having different marking patterns formed thereon. A bun holding slide is provided for holding and positioning the bun beneath the heated pattern. The detachable heating element head is attached to a support arm assembly which extends from the vertical portion of a support frame. The support arm includes a movable rod having the heating element connected for movement therewith which can be lowered so that the heated branding pattern contacts the bun and, after a selected period of time, forms a distinctive pattern thereon. When the movable portion of the support arm is lowered it activates a limit switch which starts a timer. After a set period of time has elapsed, the timer, through appropriate electrical interfaces, sets off a buzzer to indicate that the selected period of time has elapsed. The variable timer can be set to a desired time.
