TO ALL WHOM IT MAY concerts;

Be it known that we, E. A. Scenes and E. L. MILLER, both of Philadelphia, Pennsylvania, have invented an Improvement in Sewing Machines; and we do hereby declare the following to be a full, clear, and exact description of the-same, reference being had to the accompanying drawing,'a nd to the letters of reference marked" thereon. I

Our invention ccnsists in the arrangement and combination, described hereafter, of an inclined vibrating needle-arm, eye-pointed needle, and a vibrating loop-holder or carrier for making a button-hole stitch over the edges of fabrics. On reference to the accompanying drawing, which forms a part of this specification Figure 1 is aside view of suflicient of a sewing machine to illustrate our improvement.

Figure 2, the same, with the parts in difi'erent positions.

Figure 3, a front view and 7 Figures 5, and 6 illustrate the different modes of operating the loop-holder.

Similar letters refer to similar parts throughout the-several views.

A is the base of the machine, upon whiieh.is erected the standard B, and to the top of the latter is secured the work-plate G. E is the vneedle-arm,to the outer end of which is secured the ordinary eye-pointed needle n, the said needle-arm being placed at such an angle that it will carry the needle 11. in a diagonal path, coinciding with the line X X, fig. 3. Through the standard 13 passes a rod, a, upon the outer end of whieh'is a toothed pinion, e, gearing into teeth on the edge of a segment,.F, thellatter being hung to a pin, e, on the side of the standard B. To the lower end of the segment F is connecteda rod, D, which is actuated from any moving part of the'machine by suitable mechanism. To the inner end of the rod (1 is secured a curvedloop-holden b, ithrough eyes in which passes the under thread 3/, the upper thread x passing through the eye of the needle a.

who diiferent parts of the machine being in the position shown in fig. 1, (and in dotted lines, fig. 3,) and the cloth having been so placed upon the work-plate that the loop-holder b shall pass through the button-hole and in-fr0nt of the edge to be sewed, the machine is set in motion. The needle 11. descends, perforating the fabric near the edge to be sewed, until it reaches the limit of its downward movement, the loop-holder at the same time moving in the arc of a circlc through the button-hole from the position shown in fig. 1 to .that shown in fig. 2. As the needle it rises the loop-holder moves upwards, carrying the under thread through the loop of needle-thread, both holder and needle finally reaching the limit of their upward movement, as seen in fig. 1. As the needle 71 again begins its downward movement, and the loop-holder begins to recede, the thread at the side of the latter is looped suiliciently to allow the needle n to pass through it into the fabric, while the loop-holder, continuing its receding motion, draws thethread over the edge of the fabric and beneath the same. At the next movement the loop-holder carries the under thread through the loop of needle-thread at the side of the needle a, over the edge of thefabric to its first position, where the loop is again secured to the top of the fabric by the needle-thread as before. It will be observed on reference to fig. 3 that the needle,'in commencing its downward movement, passes the loop-holder on one side of the latter, and that as the needle approaches the limit of this movement it passes the loop-holder on the opposite side of'the same; in other words, the path traversed by the needle crosses that traversed by the loop-holder, and, consequently, as both needle and loopholder begin to rise, there is more certainty of the loop-holder passing through the loop of needle-thread, and both needle and loop-holder descend) of the needle passing through the loop of under thread than if their paths were parallel with each other. I

It will now be seen that the loop-carrier will convey loops of thread from the under side and, upwards across the edge of the fabric to be locked to the same by thenoedlc-thread, and that the stitch produced is precisely the same as the double-threaded stitch described in our patent of July 26, 1859,;reissucd February 9, 1864.

p In place of the rod D forimparting a vibrating .motion to the segment the latter may be operateddirectly from a rotary shaft, II, (fig. 5,) from the'cnd of which a pin, 7', projects and works in a slot, k, in the segment. in the upper edge of the lattqr are slots z',-into which project pins (1 from a disk on the outer end of the rod a so tiiat, aszthe' segment vibrates, the desired inofrement will be imparted to the loop holder. Instead of tile segment F a sliding-plate, G, may be used, 6,) the pins e on the end of the rod a projecting into slots-i on.

the upper. edge of the plate G. 1

We claim as 9111 invention, and desire t ovsecure by Letters I ?atent-- .The arrangement and combination, lierein described, of ,the inclined vibrating needle-arm E, its eye-pointed needle n, and the vibrating loop-holder or carrier 6, for the purpese specified. v
