摘要： An embroidery machine includes a base and an arm connected to an upright column post on the base. A needle bar is movably connected to the arm and a needle frame is connected to a distal end of the needle bar. A needle unit is connected to the needle frame and removably extends through the holes in a needle plate on a top of the base. An alignment device is connected between the needle bar and the needle frame so that the needle frame can be connected to the needle bar by a guidance of the alignment device.

摘要： A main needle holder is disposed above a needle plate, and has a screw portion for fitting a needle bar. A sub needle holder is fitted to the main needle holder by a set screw so as to be adjustable in position. Fitting position of the sub needle holder to the main needle holder is changed when loosening the screw, so that the interval of the plural needle is widened or narrowed in the longitudinal direction. Plural needles are individually fitted to the needle holders, and penetrate through a needle hole of the needle plate when descending. The fitting position of the sub needle holder to the main needle holder is changed by a longitudinal slit formed linearly on the main needle holder, and the cloth penetration lines by at least two needles of plural needles can be mutually set along in a narrow width.
摘要翻译： 主针架设置在针板的上方，具有用于安装针杆的螺纹部。 副针架通过固定螺钉装配到主针架上，以便可调节位置。 当松开螺钉时，子针架的配合位置变化到主针架，使得多个针的间隔在纵向上变宽或变窄。 多针单独装配到针架上，并在下降时穿过针板的针孔。 通过在主针保持架上直线形成的纵向狭缝来改变副针保持架到主针架的装配位置，并且可以通过至少两根针的多针的布线贯穿线沿狭窄的宽度相互设定。

摘要： A thread consumption detecting apparatus includes an axial supporting shaft, a detector lever, a torsional spring, a proximity sensor, and a central processing unit (CPU). The detector lever includes an intermediate portion, a loop-shaped thread-contact end, and a base end. The intermediate portion is fitted idly around the supporting shaft so that the detector lever can swing. The thread-contact end is disposed so as to pass a thread outside the loop-shaped portion. The base end is detected by the proximity sensor. A swinging stroke of the detector lever is disposed so as to interfere with a thread-transfer-route variation range resulting from a fluctuation in tension of the thread. The torsional spring urges the detector lever in one swinging direction. The proximity sensor detects the base end on approach when the detector lever is swung by the tension of the thread. The CPU judges whether the thread is consumed or not in accordance with a signal output from the proximity sensor.

摘要： A device for holding a sewing needle which has a cylindrical shank, an arcuate portion, and a flat wall portion, in a needle bar which has a longitudinally extending receiving groove with a flat interior receiving wall comprising a locking member. The locking member has a longitudinally extending bridge part with outwardly extending arms engageable around at least a portion of the circumference of the needle bar. The arms include an upper abutment arm extending outwardly of said bridge portion into the needle bar groove and defining a stop against which the top of the needle bar is engageable. The construction includes a lower abutment arm extending outwardly from the bridge engageable with an arcuate end over the arcuate portion of the shank so as to hold the flat portion of the shank of the needle on the flat interior receiving wall of the groove.

摘要： A sewing machine having a mechanism for operatively disengaging a needle from a needlebar when the needle hits an impenetrable object. The needle is provided with a transverse slot which normally engages the end of a movable pin which pin holds the needle in fixed relation to the needlebar. An adjustable spring in turn tensions the pin to a preselected position whereby excessive forces on the needle occasioned by hitting an impenetrable object overcomes the force exerted by the spring on the pin thereby allowing operative disengagement of the needle from the needlebar.
