You can find out more about old sewing machines by going to the website of the International Sewing Machine Collectors Society.
I have an old White Family Rotary machine #FR3084622.
Singer sewing machines date to 1851 when Isaac Merritt Singer started a sewing machine company.
Singer was convinced he could design a better sewing machine than the available models of that time.
In a modern sewing machine the fabric easily glides in and out of the machine without the inconvenience of needles and thimbles and other such tools used in hand sewing, automating the process of stitching and saving time.
