History of Bishop-Wisecarver
If you've ever bought a loaf of bread, a mattress or fertilizer for your garden, you've likely benefited from the ingenuity of Bud Wisecarver. For almost 80 years, Bud's life has been ruled by two main themes: Motion and innovation. Many businesses from a variety of industries have benefited from his company's products, which have been designed with one question in mind: How can this industry work more efficiently?
The following timeline outlines Bud's history of innovating products that help businesses run more smoothly — from manufacturing screw machine parts to patenting linear motion products.
In fall of 1950, Bud started W.R. Wisecarver & Company to manufacture truck accessories. While there, he was approached by windows, blinds and drapery manufacturer Levelor to rebuild their plant up to modern standards. The project took three years to complete. Efficiency had doubled, the linear footage produced considerably increased and the plant was running 24 hours a day with the same number of employees originally running six hours a day. And Bud was out of a job.
Bud began manufacturing screw machine parts and this endeavor attracted a new client, bread tray salesman Ray Bishop. Ray asked Bud to help him design an improved product to secure bread trays during transport. The result was Saf-T-Sta, a cargo bar that streamlined loading and unloading delivery trucks. He later built a specialized bread tray for Ray known as the Flo-Carri.
- 1962: A patent is issued for Saf-T-Sta. Later that year, Bud moves W.R. Wisecarver & Company from Cowell, Calif. to the nearby city of Pittsburg.

- 1968: Bishop-Wisecarver buys property in Pittsburg, where the company has stayed ever since. Out of frustration with current technologies, Bud begins toying with Vee wheels. He designs DualVee guide wheels while watching an Oakland Raiders football game. They remain the company's signature product. Bud also designs and builds the Radius Machine for box spring manufacturers the same year.
