This patent covers a power feed mechanism where the drill spindle is moved manually until it reaches a pre-set position, whereupon the power feed engages and advances the drill forward.
This patent covers advances created by the inventor while he was working for Grant Sipp of Sipp Machine Company. He had been hired expressly to design a sensitive drill. The patent is not assigned to Sipp or his company, and so not surprisingly, a lawsuit resulted. There was no written agreement as to who owned the intellectual property created during Mr. Widmer's employment. The court ruled, in a split decision, that Sipp owned most of the ideas, but those related to planetary gearing were "not a mere ancillary improvement on the regular machines of the company" and remained with the inventor. |
