. Bulletin - United States National Museum. Science. Figure 48.—Hever's pocket sewing machine patent model, November 17, 1863. This patent model is one piece, and measures about two inches in height and two inches in length. It will stitch—but only coarse, loosely woven fabrics. As can be expected, a great deal of manual dexterity is required to compensate for the omission of mechanical parts. Heyer advertised patent rights for sale, but evidence of manufactured machines of this type has yet to be discovered. (Smithsonian photo 18115-D[a].)

Figure 49.—Heyer's machine as illustrated in Sci- eniifa American, July 30, 1864. The smallest and most original of all the attempts to simplify machine sewing, Heyer's machine, which made a chain- stitch, was constructed of a single strip of metal. The Scientific American stated: "It is simply a steel spring ingeniously bent and arranged and it is said to sew small articles very well. The whole affair can easily be carried in the coat ; One method of operation, vibrating with the linger, was illustrated. The machine could be operated also by holding it in the hand and pres- suring it between two fingers. Cloth was inserted at c, and the prongs of the spring feed / carried it along after each stitch. It was stated that the needle could be cut from the same strip of metal, but it was advised also that the needle could be made as a separate piece and attached. (Smith- sonian photo 48221.) %V.
