Canadian Patents Issued, 18 March 1893

Introduction

1893 was a time of significant technological and industrial advancements. It was also an exciting time for inventors. Many new inventions and innovations were made in fields such as transportation, communication, and manufacturing. The Canadian government was also making efforts to support the growth of Canadian industry, which included the promotion of Canadian inventors and their inventions. Many Canadian inventors and entrepreneurs were creating new businesses and filing patents in various fields, such as agriculture, construction, mechanics, and electrical engineering. Previously, in 1891, the Canadian government established the Patent Office which was responsible for granting patents and promoting the interests of Canadian inventors. The patents listed here are some of the earliest Canadian patents ever registered.

It is worth noting that while it was an exciting time for Canadian inventors, it was also a challenging one. There were limited opportunities for Canadian inventors to commercialize their inventions, as many of the large markets were dominated by foreign companies. Additionally, the Canadian economy during this time was heavily dependent on the export of natural resources and raw materials, which made it difficult for new technologies and industries to establish themselves. This period was an exciting time for Canadian inventors but it was also a challenging one as they were facing some obstacles in commercializing their inventions.

Patents issued this week

They cover a wide range of different inventions and industries, from compasses for ships to foot rasps for horses to mail cancelling machines. Out of the patents listed on the page, here are three that would be of most interest to the modern reader:

• Patent 42323 Flooring and other lumber — This patent would be of interest to modern readers because it describes a new method of treating and preserving wood to make it more durable and resistant to decay. The patent outlines a process of impregnating wood with various chemical solutions and then heating it to a high temperature to create a hard and durable surface. This method is still used today in the production of pressure-treated lumber.
• Patent 42327 Apparatus for raising and lowering Incandescent Electric Lamps — This patent would be of interest to modern readers because it describes an early method of adjusting the height of electric lamps using a simple pulley system. While this may seem like a minor innovation, it was an important step towards making electric lighting more practical and efficient in homes and businesses.
• Patent 42338 Process of obtaining Bromine from natural brine — This patent would be of interest to modern readers because it describes a process for extracting bromine from natural brine, which is still used today. The patent outlines a method of mixing the brine with chlorine gas and then distilling the resulting solution to extract pure bromine. Bromine is an important industrial chemical that is used in a variety of applications, including pharmaceuticals, pesticides, and flame retardants.
