" NEEDLE HOLDER FQR snwrne M'AcinnEs Application filed March 2i? The present invention relates to a needle holder for sewing machines of the'two or multiple needletype and has for its primary object to provide, in a'manner as hereinafter 75 set forth, a holder of this character embody-\- ing; as novel .construction, combination and arrangement of 1 parts through "the *IIlBdllllIl of which the needles may be independently and selectively; shifted to tion when desired a I a i 'Another very important object of the in vention' is to provide a needle holder for sew-- ing machines embodying novel means for re-, leasably securing the needles inoperative or inoperative position.

I v Inuse; the needles 'lOare secured in opera- Y 'tiveposition: by engaging the detents 13 in the lowermost sockets 14. When it isdesired to shift one ofthe needles to inoperative po- V sition,the detenty13 of the slide 6 in which; i said one'needle is mounted is withdrawn from i the lowermost-socket through the'medium of its respective bell'crank lever 17 and the slide is raised throughithe mediumof-the bracket 11 mounted thereon; until the detent engages in the uppermost socket 14.1, Thus,

the slide is secured in raised position; A stop screw 201s threaded into the lower end of:

the head portion 3, the head of saidscrew 20 projecting into the slideways 4 and constitut: ing a stop for arresting the downward movement of the slides 6. v 5 It is believed that the many advantages of a needle holder for sewing machines constructed in accordance with the presentinvention Will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall Within the scope of the inven-i tion as claimed. It is further understood that the device may be adapted to accommodate any desired number of needles. What is claimed is 1 A needle holder for sewing machines comprising a supporting member attachable tothe sewing machine and having a plurality of slideways therein, slides adjustably mounted in the slideways, said slides having sockets therein for the reception of the nee'dles',/the

inner walls of the slideWays having vertical ly spaced sockets therein, the opposed walls ofthe slideways having-grooves therein, ribs on the slides engaged in the grooves, brackets mounted on the slides, common means for securing the brackets and the needles on the s slides, spring-pressed detents slidably mounted in the slides and engageable selectively in the socketsforreleasably securing the needles in operative or inoperative position, said dejtents including reduced portions, and bifurcated bell crank levers pivotallymounted on the brackets and operatively engaged with the detents for disengaging said detents from the sockets, the bifurcations of the bell crank 40 levers straddling the reduced portions of the detents. 1 V In testimony whereof I afiix mysignature 1 FIORINDO BASSO.
