Elias Howe is famous because he invented the sewing machine and the lockstitch loop method.
Per the Wikipedia article on "lockstitch", the term single needle stitching, often found on dress shirt labels, refers to lockstitch. Most home sewing machines are lockstitch machines.

Elias Howe sued Isaac Singer for patent infringement over the invention of the sewing machine. Howe had patented a sewing machine design in 1846 that featured a lockstitch mechanism and an eye-pointed needle, while Singer's machine used a similar concept. Howe claimed that Singer's machine infringed on his patent, leading to a significant legal dispute in the 1850s. Ultimately, the case underscored the complexities of patent law in the rapidly evolving industrial era.
Elias Howe obtained the patent for the first sewing machine to use a lockstitch. He won a 6-year court case against Isaac Singer, and earned considerable royalties from Singer and others for having sold his invention. Elias went on to invent the zipper.
There are many more than two types of sewing machines, but the two most common are the Lockstitch and the Chainstitch. A chainstitch machine uses only one thread, which is looped around under the fabric and around itself, forming a "chain" under the fabric. A lockstitch machine uses two threads - one on top and one beneath the fabric being sewn. The upper thread is passed through the fabric by the needle and is looped around the bobbin, which contains another small spool of thread the bobbin thread "locks" with the needle thread, giving the lockstitch its name. Lockstitch looks the same on both sides of the fabric.Types of Sewing Machines Each machine makes a basic running stitch the same way, with two sources of thread. The top needle takes the thread down into the fabric. It is caught and looped via the bobbin apparatus and then pulled back up. The "feed dog" (a rough edged surface underneath the fabric) moves it along and the next stitch begins. Everything else is different.Mechanical Sewing MachinesA mechanical sewing machine is controlled by a rotary wheel. Any adjustment like the tension or the length or width of the stitch is made by moving a dial. These machines are very basic and tend to be less expensive than the other sewing machines. Electronic Sewing MachinesAn electronic machine differs in that there are some functions that can be accomplished by pushing a button. A machine can have a number of motors for various duties and they are run via electricity. Computerized Sewing MachinesAs sewing machines became more complex, more of these motors were added. A computer then coordinates all these functions. Think about a repetitive sequence of stitches being programmed, so you no longer have to replicate these movements over and over again.
The lockstitch is the stitch most sewing machines perform, which takes two threads. One thread passes through a needle (above the fabric), and the other comes from the bobbin (below the fabric). Each thread stays on the same side of the material being sewn. The sewing machine interlaces the two threads at each needle hole, by means of a bobbin driver.
