IMPROVEMENT IN SEWING-MACHINES.

Specification forming part of Letters Patent No. 152,260, dated June 23, 1874 application filed December 3, 1873.

To all whom it may concern:

Be it known that I, MELZER G. TURNER, of Westborongh, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification:

The nature of my invention consists in combining, with the needle and hook of a strawsewing machine, of the kind for which a patent was granted to Sidney I. Turner August 24, 1869, No. 94,046, a new loop-holder, said loopholder consisting of two flat spring-plates moving across the paths of the needle and hook, one plate being at each side of the needle and hook at all times, each plate being provided with a point and an extension, the two points of the plates forming, together, a single point for taking the loop, while the two extensions of the plate form guides for the loop-holding point and insure its action.

Figure 1 is an elevation, showing the needle and hook in connection with my loopholder. Fig. 2 shows the loop-holder in plan. Fig. 3 shows the loop-holder and needle and hook in elevation, the parts being in the position assumed for casting off the loop by the loopholder.

B is an ordinary eye-pointed needle; 0, a hook-needle and Athe throat-plate--all made and arranged to operate as described in the specification of the patent above referred to. D, Fig. 1, and D D, Fig. 2, show the new loop-holder. This consists of two spring-plates, D and D, each of which is shaped as shown by D, Fig. 1. Each of these plates has a point, the two points E and E being combined, as shown by E E, Fig. 2, to form the single com pound point or loopholder and cast-off. These plates have extension-pieces F and F, Fig. 2, which serve as guides for the whole looper.

through the stock, dropping back to form the loop, which is caught on the looper, (not shown then the needle descends, and the hook O comes up through the stock and takes the loop (which is released from the looper) and carries it down through the stock and below the point E E of the loop-holder; now, the loop-holder passes forward and catches the loop, as shown at Fig. 3. The hook then passes up between the two plates D D, and leaves the loop upon the points E E, and then retreats to its lowest position, leaving the loop on the points E E. Now, the loop holder returns with the stock as it is fed along into such a position that the; needle B in its upward stroke passes through" The conthe loop which is held on the holder. tinned retreat of the loop-holder casts off the loop and leaves it on the needle B. This completes the operation of forming one stitch.

I claim as my invention- The combination of the needleB and hook O with the two hooked plates D D, arranged to operate as a loop-holder, substantially as described, and for the purpose set forth.
