  • a fastening screw 39 Mounted upon the bottom surface of the throat-plate 23 by ⁇ means of a fastening screw 39 is the shank 40 of the thread-guard having a reduced portion 4l and an active edge 4?.. The fastening screw 39 passes through an enlarged aperture 43 in the thread-guard thereby permitting the thread-guard to be adjusted lengthwise and sidewise of itself. As may be best seen in Figs.
  • the thread-guard is disposed inparallel relation with the throat-plate and the active edge 42 is spaced from the throat-plate andunderlies and extends across the elongated needle-aperture 38, in a direction transverse to the direction of feed.y Having the active portion 42 of the thread-guard spaced from the throatplate 23r prevents the cast-off needle-loop 50 from being caught between. the throat-plate and the thread-guard. ⁇
  • Figsf? and 8 illustrate a body material 44 having a line of loosely set-up single-thread chainstitches placed therein. It is to be noticed thatv in orderto provide the proper amount of elaspending from beneath the under surface of the material. l In Fig. 4 of thedrawings, the needle Il has just begun to riseand the beak 48 ofthe looper is about to enter the needle-thread loop 41 formed by the rising needle and it is also about to enter the loop 48 of thread previously expanded by the looper and detained at this time in the throat 46 thereof. Just prior to this time the loop 5I! ⁇ was cast off from the looper and it was drawn up through the needle-aperture by the combined actions of the take-up and feeding mechanisms.
  • the present thread-guard has been provided so that its active portion 42 will engage the loop 5l] as the work is being fed prior to the descent of the needle and wipe such loop upwardly and in a direction opposite to the direction ofv feed, thus removing the loop from the path of the looper.
  • the active portion 42 of the thread-guard is sustaining the loop 50 in its upwardly deected position and therefore the looper beak 48 cannot engage the same.
  • the feeding mechanism will shift the work past the needle-aperture to thus completely vdrawthe loop 50 up through the needleaperture.
  • thread-carrying needle means for reciprocating said needle, a rotary chain-stitch looper cooperating with said needle in the formation of stitches, needle-thread take-up means, a throatplate, means to feed the work over the throatplate, and a thread-guard disposed below said throat-plate, said thread-guard'being adapted tov engagevthe cast-01T needle-loopand to deflect saidy loop upwardly and in a direction opposite to the direction of feed.
  • said looper having yits loop-seizing movement in the direction ,of the feed ofthe work,v needlethread take-up means, a throat-plate having a needle-aperture, therein, and a thread-guard having its active portion underlying and extending across said needle-aperture at a point rearwardly of the needle-path, said thread-guard bev ing adapted to engage the cast-off needle-loop and to deiiect said loop upwardly and in a direction opposite to the direction of feed. 3.
