Home selai mesin are designed for one person to sew individual items while using a single stitch type at a time. In a modern selai mesin, the process of stitching has been automated so that the fabric easily glides in and out of the machine without the inconvenience of needles, thimbles and other tools used in hand sewing. Early selai mesin were powered by either constantly turning a handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced.

After a lengthy stay in England trying to attract interest in his machine, he returned to America to find various people infringing his patent, among them Isaac Merritt Singer. He eventually won a case for patent infringement in 1854 and was awarded the right to claim royalties from the manufacturers using ideas covered by his patent, including Singer.
Singer had seen a rotary sewing machine being repaired in a Boston shop. As an engineer, he thought it was clumsy and decided to design a better one. The machine he devised used a falling shuttle instead of a rotary one; the needle was mounted vertically and included a presser foot to hold the cloth in place.

When Howe learned of Singer’s machine he took him to court, where Howe won and Singer was forced to pay a lump sum for all machines already produced.

They created the first hire-purchase arrangement to allow people to buy their machines through payments over time.
