The Singer Corporation was first established with a mission to cater for domestic sewing machines. From 1851, the company has been synonymous with anything sewing. Over the years, it has gained popularity to be one of the leading service providers in the sewing industry putting out classic models like the Singer Model 15.
The company incorporated both creative innovation and practical designs when it came to sewing machines. This saw it produce the first practical sewing machine. It has also invented other features that have seen the sewing industry grow in leaps.
These include the first electric machine, first zigzag machine, first sewing application for mobile devices on the go and many others. Singer has used their brand to inspire sewists through embroidery, home décor and many more.
The Singer Model 15
Among the first sewing machine to be produced, was the Singer Model 15. It was mechanically altered in appearance from the original family machine. It initially came with a fiddle shaped table or a hard crank machine. The model also came with cabinets.
The model turned out to be one of the most successful in the industry for more than 100 years. During this period the model underwent several innovations to improve on its performance.
A notable feature of the model was the tension assembly. Instead of being at the front of the sewing machine, it was located in the faceplate. With the introduction of the model, it came with a new needle design. This was allocated the designation 15 by 1.
The needle design was essentially adopted in subsequent Singer sewing machines and other companies. Over the years, modifications have been done on this needle design. It is also found by the designation 130/705H or 2020.
The model did not have a separate removable bobbin case. This however changed with the innovation of Model 15-11. This new design has been in use ever since. Its bobbin case was loaded vertically and it allowed for adjustment of the thread tension.
The bobbin case was accessible below the slide plate or the machine itself if it came with cabinets or a treadle. The case has a hook that locks into a notch to secure it in place when sewing. The bobbins remain standard over the years.
