ShOOL-HGLDER FOR EMBROIDERY-MACHINES.

Specification of Letters Patent. Patented Mar. 15, 1910.

Application filed October 22, 1909. Serial No. 523,9 75.

To all. 711M991 it may concern:

Be it 'known that I, JACOB FREY, a citizen of Switzerland, residing at New York city, Bronx, county and State of New York, have invented new and useful .lmprovementsin Spool-Holders for Embrdidery-Machines, of which the following is a specification.

This invention relates. to a spool holder which is adapted to be mounted upon a reciprocative shaft of an embroidery machine, and is provided with a pl1::ality of spools, each having its own needle. The spools are designed to carry threads that differ in thickness, quality or color and thus, by turning the shaft in its bearings, threads of diffcrent characteristics may be presented to the work without removing the spools or rethreading the needles.

.In the accompanying drawing: Figure l is a front view of my improved spool holder, showing it mounted upon the shaft of an embroidery machine; 2 an end view of o a section on line-33, Fig. '2.

As is well known, an embroidery machine is provided with a large number of threadca-rrying needles mounted side by side upon a shaft which is adapted to receive reciprocative movement. The fabric to be embroidered is stretched upon a frame which is adapted to be shifted relatively to the neeles in accordance with the particular pat- "Earn to be produced. As the needles do not participate in the movement of the fabric, they will, upon being reciprocated, form the pattern desired As heretofore generally practiced, the spools supplying the needles were removed and replaced, and'the needles were re threaded whenever the quality, thickness or color of the embroidery thread was to be changed, thus entailing considerable labor and loss of time. By my invention this substitution of threads may be effected ..simultaneously for all the needles in a quick and simple manner and without necessitating the removal of any of the spools or the re-threading of the needles.

The drawing shows a single spool holder mounted upon a rcciproc'ative shaft 10 of the embroidery machine, but it is to be understood that in practice a large number of such holders are mounted side by side upon such shaft. The spool holder is composed of a tubular sleeve or head 11 encompassing shaft 10 and adapted to be firmly secured thereto by set screw 12 or otherwise. Sleeve i 11 is provided at one end with a plurality of 5 radially extending arms 13 to which are fulcrumed at 14 the spindles 15 0f the spools 16 which are rotatably mounted on said spire dles. The drawing shows four of such spools, each designed to carry a thread of different texture or color, but it is obvious that the number of such spools may be varied at pleasure. The free end of each spin die 15 is supported within an aperturcd spring. bearing 17 secured to sleeve 11 and which, on being swung outward, liberates spindle l5 and permits the latter to be turned on its pivot 14, so that spool 16 may be removed and replaced whenever neccs sary. The tension of'spool 16 may be regulated by means of a nut 18 mounted upon a threaded section bf spindle 15 and bearing against one end of a spring 19 coiled upon spindle 15, the other end of such spring engaging one of the heads of spool 10. Intermediate each pair of spools 16, there projects from sleeve 11 a rib needle or holder 20 bored, as at 21, for lhea'cccption of a radially extcnding needle. 22 which is clamped to its holder by screw 23. The thread 2+ from each spool passes to the eye of its respective needle, so that in this way each nccdle carries a thread possessing its own individuality. It is preferred to split sleeve 11 longitudinally, its two semi-circular halves being united by screws 25. By this construction each holder may be readily rcmovcd from shaft 10, for the urpose of pair and may be rc-fitted in position, with out interfering with any of the other holders. Shaft 10 carries a handle 26 and is rotatabl y mounted in swinging bearings 27, towhich it may be locked by a set screw In practice, the sleeves 11 are so positioned on shaft 10 that all those needles which carry the same quality of thread :24: are presented to the fabric. If it is desired to change the embroidery thread, screw 28 is slackened and shaft 10 is so turned by its handle 26, that the needles carrying the seafter which the shaft is rc-locked to its bearings. In this way the desired exchange of threads is effected in a simple, quick and citrlected threads are pointed toward the work,
