I started looking for the patents listed by date on Domestic slide plates. This led to finding other Domestic patents plus some by Standard and one by King that appear on Domestic machines. The following chart shows the patents I found with some summary information. If you can help me fill in the DNF (Did Not Find) blanks, please contact me!
Multiple models have the same patents so I made numbered groups.The key to which machines are in which group is at the bottom of the chart.You will need to view this huge image on a full size screen. Click to view full size
