All of these patent items have a link to a PDF of the original patent. The Canadian patent PDFs tend to be quite large and may take a long time to load.
I have appended letter indicators to each patent to help in identifying the source of the patent data. These identifiers are not a "real" part of the number. I did this so that I can intermix the numbers with patents assigned to other manufactures and then sort them together and get a single combined list of patents in numerical/date order while being able to indicate the source of the data.
Please note that the major sites that I downloaded data from have more useful data and I recommend connecting to their sites to get the best idea of these patents.I have obtained this collection of patent data from several locations. To indicate which patent set that this information came from, I have appended an identifying letter:
https://patents.google.com/patent/USxxxxx" with the "
xxxxx" replaced with the patent number you want more information about.
In many of the referenced patents there is little of interest to someone trying to learn something about saws and the tools that are used to maintain them. This is because I copied the works of others and decided against editing their choices of patents to include here.
There are 4 "fake" patent numbers which I assigned to very early patents that were listed by the "Saw Set Collector's Resource" that indicated these patents were issued "before patent numbers started".
In many places in the Atkins patent set, inventor Poindexter is referenced, while the patent does not specifically say that the patent was assigned to Atkins. It is assumed that the patent was assigned to Atkins since he had worked for several years for E. C. Atkins & Co. His employment at the time of this patent is unknown.
As I find further patent information, I will append a "M" to the patent number to indicate that this is from a "Miscellaneous" source.
There are several cases where the same patent is referred to more than once. As I find these, I will delete the extra references.
I made an attempt to read the actual PDF of the patent to get much of my information. I discovered that the title on the first page did not always accurately describe the patent. I chose not to carefully read each patent and just used the patent's name as it was on the first page.
In reading the patents it was a surprise that there were no dimensions on the drawings.
I have numbered each patent entry. Some browsers do not display this number in a reasonable manner. However most do.
