IMPROVEMENT IN SEWING-MAC'HINESL Specification forming part ofLetters Patent No. 21,: 3 1. dated August 17. 1858.
To all whom, it may concern Be it known that I, TIMOTHY D. JACKSON, of the city, county, and State of New York, have invented anew and useful Improvement in Sewing-llIachines; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, figures, and letters of reference thereon, making part of this specification.
' making the tambour or chain stitch, such 1nachines being in general use.
In all machines of this character the great desideratum is to prevent the dropping of stitches and consequent injury to the seam arising therefrom.
To this end the nature of my invention consists in the employment and use of a thread guide so constructed and arranged that it may be operated entirely by the needle and a spring, and in combination with a hooked or barbed needleinsure the taking of every stitch, and thereby produce a simple andeffectual tambour-stitch sewing-machine.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
A represents a metallic frame, cast in a single piece, so as to form the arched arm, (mounted by the adjustable cloth-holding bar 13,) and so arranged that it may readily be clamped to a table by means of a screw, as plainly in- O is-the cloth-holder. D is the table for supporting the work. E is the spool supplying the thread. F is a spring having its fulcrum at t, and, operating by the screw h and cones j and k on the spoolspindle Z, produces the tension on the thread, as plainly shown in Fig. 1. G is the shaft,
having secured at one end a wheel, K, and
plate 0 (and which is adjusted to the material to be sewed by the set-screw J is secured, by a proper fulcrum at a, the thread-guide a, which is operated entirely by the hooked or barbed needle (Z and springs c and b, which are plainly shown in all the figures.
Operation: The cloth being adjusted to the table D by the cloth-holder G, and held firmly by the screw J, and motion being given the crank-shaft G in the direction of the arrow, Fig. 2, causes the needle (I to pierce the goods (the plate being slotted for this purpose) from below, and as it oscillates takes with unerr-ing certainty the thread which is passed through. the eye of the thread-guide 4, Figs. 1 and 2, and draws it in its return movement, being held to the hooked needle by the guide a until the needle leaves the goods, when the thread guide a, by the action of the springs c and 1), comes into position, and is held by the pin m in the cloth-holder for another stitch, and the needle returning through the loop thus formed into the cloth and repeating the operation produces sewing. The feeding of the material is effected by the oscillating of the needle during the formation of each stitch.
In the wheel M, which works the needlestock, there are a series of holes, 1 2 3, all being of different relative positions to the center, and to change the feed or length of stitch is only necessary to change the position of the needle-stock to or from the center of the wheel M, which is done by the screw f. The needle is secured in the stock by the set-screw c, and must be adjusted for thick and thin ma terial, so as to insure the taking of the thread for the stitch.
Having thus described my improved sewing-machine, I will state what I claim and desire to secure by Letters Patent.
I am aware that thread-guides are used in single-thread machines to convey the thread across the path of the needle, which receive their movements from mechanism other than l needleconstructed substantially as described, the needle, an example of which may be found whereby I am enabled to secure the taking of in the patent of O. L. Reynolds, May 14, 1850, every stitch and render a single-thread ma- I claim TIMOTHY D. JACKSON.
and I therefore disclaim all such; but i chine effectual, as set forth and specified.
