Latest Patents

One of Holtkamp's latest innovations is an advanced oven thermostat designed for self-cleaning ovens. This device employs a hydraulic sensing system featuring a wafer-like bellows, which adjusts its position via a face cam linked to the control shaft during the BAKE and BROIL modes. Notably, the bellows also regulates the temperature for the self-cleaning process without influencing the self-cleaning temperature set by the face cam. This invention includes three separate calibration adjustments to ensure accurate operating temperatures across different modes, as well as a bimetal ambient temperature compensator to account for environmental variations.

Another noteworthy patent is a push-to-turn thermal cycling switch aimed at regulating the wattage of a resistance-type surface heating unit in domestic electric cooking ranges. The switch innovatively cycles on and off based on the position of a bimetallic element, thereby adjusting the heating unit's duty cycle. The unique design includes a disc cam member mounted on a rotatable shaft, which features a detent mechanism for transitioning to the 'off' position. This invention simplifies machine assembly and decreases manufacturing complexities.

Career Highlights

Throughout his career, Holtkamp has worked with reputable companies such as White Consolidated Industries, Inc. and Robertshaw Controls Company. His tenure at these organizations allowed him to hone his skills and explore inventive solutions within the cooking appliance sector.
