The Universal Stamping Machine Company sought patent protection in 1910 or shortly thereafter in the US, Canada, France, Austria and Switzerland. Additonal patents were obtained in later years as well. We have found the following Canadian patents. Clicking on the titles will reveal/conceal an extract from the periodical Canada Patent Record. (The files are large so may take some time to appear.) These are the published summaries --- the full text patents (before 1920) are not readily available.
