The sewing-machine, of which a representation is now given, is about twelve inches square, and is driven by a wheel at the end of a main shaft which passes through the machine. The wheel can be driven either by the hand, foot, or steam-engine. From the top plate of the machine and at the side on which the wheel is placed, an arm rises to about ten inches and extends to the opposite or front side, in which arm is worked a lever which drives the vertical needle. This needle is attached to a sliding bar, worked by the arm. Underneath and below the plate of the machine is another needle of horizontal shape, which is fed by a bobbin or reel of thread also out of sight. Imagine the vertical needle as being threaded and supplied by a reel on the top of the arm, and the horizontal needle threaded as described, and the machine put in motion; the vertical needle would penetrate the cloth or other material, say half an inch below the surface, and, on being drawn back by the action of the machine, would leave a loop; when this loop is formed, and at the exact time, the horizontal needle enters it and holds the thread until the stitch is formed, when by a counter action it revolves back and throws the loop off and takes another. The machine is capable of stitching every part of any garment, except the buttons and button-holes, whether the work be light or heavy, coarse or fine; also for gaiters, boots, shoes, sacks, bags, sailcloths, tents, &c. &c. It is so simple in its construction and action that it may be worked by a child, and will sew a circle, curve, or turn a square corner, equally as well as a straight line. It is only twelve inches square, and is driven by the hand or foot. By the action of a screen in the machine, the stitch can be either lengthened or shortened, as may be desired. The machine feeds itself with both cloth and thread, and it is only necessary for the operator to guide the material to the needle to sew. It will with ease sew a yard per minute, stronger, more uniform, and consequently better than it is possible to be done by hand.
