Treadle Sewing Machine Parts and Functions: Understand Them Now

What comes to mind when you think of a treadle sewing machine? Probably the sewing machine that your grandmother used for stitching clothes for the entire family; now that sewing machine is hidden somewhere in the attic collecting dust or maybe it’s now on sale at a shop that sells antique items.

 

Both of this could be true; your grandma’s old treadle sewing machine could either be hidden in your attic or it could be part of an antique shop. First introduced to the public by Isaac Singer in the 1850s, the treadle sewing machine became an instant hit. This was the first time the average woman could stitch clothes, curtain, and other fabric for your house and family in the comfort of her home. The treadle sewing machine was a truly remarkable invention.

How the Treadle Sewing Machine Works

A reminder of America’s industrial knowledge and might, a treadle sewing machine is a mechanically powered machine operated by pushing back and forth a foot pedal manually. Today, the treadle sewing machine is found at antique shops, in auction houses, at garage sales, and even in junk stores.

If you’ve never used the treadle sewing machine or seen anyone use it, then you may want to know how this classic sewing machine works. If that is the case, then you’re in luck; we are going to provide you with the details of how the treadle sewing machine works.

 

A large rubber belt is used to operate the treadle sewing machine; this belt stretches from the balance wheel to the bigfoot pedal at the lower side of the machine. Most treadle sewing machines do not have any feature for adjusting the stitch length. In other words, only a single straight stitch is possible with most treadle sewing machines. However, the most durable, delicate, and aesthetically pleasing stitches are produced by these sewing machines.

 

Unfortunately, treadle sewing machines have become a bit of folklore with the advent of electric-powered sewing machines; these machines are faster and more efficient than the treadle machines. Over the years, sewing technology developed and the electric-powered machines became increasingly advanced; this pushed the treadle sewing machines further into the background.

 

Today, people prefer to use electric-powered sewing machines over the treadle machines because they offer increased utility and many decorative stitches. However, treadle sewing machines have not completely faded into obscurity. Many people have preserved and maintained the treadle sewing machines or their parents, grandparents, and even great grandparents to this day.

 

Some of these sewing machines have a black head with gold decals and a cabinet with several drawers on each side. These drawers are used for storing sewing accessories such as needles, pins, thread, scissors, a tape measure, lubricating oil, and extra bobbins. Now that we have a basic idea of what a treadle sewing machine is and how it works, we can move onto the discussion on the treadle sewing machine parts and functions.

4. Bobbin Case

This is where the bobbin lies. The bobbin case not only holds the bobbin but it also provides the lower thread with tension. The needle wraps around the bobbin thread, as it is pulled around the case that holds the bobbin. Additionally, the needle thread is pulled up through the needle plate.
