Specificationof Letters Patent.
Application filed otobcr 21,1905. Serial No. 283.753-
Zfo .all whom 'itv my concern:
Be it known that I, vWILLIAM WILSON, a
citizen of the United States, residing at'Boston, in the county of Suiolk and Statev of Massachusetts,- have invented. certain new' andy usefull Improvements in Sewing-Machines; and I do hereby declare the followneedle ',erating uponthe work ad'acent to the nee or awl; and the object o theinvention-is to lmprove the' means by which such tools are lustment and security accompanying draw' mounted u on and secured' to the needle-bar or the fawlar with respect to facilityof adereinafter pointed out.
The inventionconsists in a` sewing-machine embodying ysubstantially the construction hereinafter described, and illustrated in the in Which- Figure 1 shows in e evation a portion of a 2 is an elevation of the needlear, and grooving-tool. tion of the grooving-too 'sewing-machine including the needle-bar provided with a needle and agroovin tool. Fig. v needle, 3 is 'a vertical sec- Fig.-4 is a'vertical section of the claming-sleeve. Fig. 5 is a vertical section of tllie upper art of the lnee-` dle-bar, and Fig. 6 is an e ovation of the growing-tool asseen from right to in 2. 1he invention, as shownin the drawin iser'nbodied in a ooving-tool securedto t e needle-bar; but 1t is equally adapted for use inconnectlon with other tools for operati adjacent to the needle or awl, such as stitc separating'or `finishing tools, and the tool may be secured to the awl-bar instead of the needle-bar. -.Th sewing-machine as a whole is not shown,` as it may be of any usual' or suitable form. t
-In the illustrated embodiment of the inm the frame 3 of the machine and carries a hooked needle 4 and a grooving-tool 5.
and in other respectsl vention the needle-bar 1' slides in a recess 2' ada ted toy operate in the manner described in t e atent to Wheeler, No. 446,398. The
needl'ear is provided with a reduced ex- .tremityll and a socket 6, in which the shank of the needle is held b aperin and splitting t e end of the needlear. vtrall perforated or the 4reception of the needle and provided with a tapered recess 9, Iwhich engages the tapered jaws?. A clamp- Patented Oct. 80, 1906.
e grOoving-tool 5 has a shank'8 cen- -grooving-tool is Of the form shown, and is jaws 7,. formed by ing-sleeve is provided withright and left hand threads which engage corresponding threads on the needle-bar 1 and theshank 8 of the grooving-tool, and the upper endof the sleeve 10 is squared for the convenient appli- -cation of a wrench in turning it. 1 `When the parts arein place, a partial turn .of the sleeve,
10 draws the shank 8 tightly against the jaws 7, thereby forcing the jaws against the needle-shank and simultaneously securing the needle -and the grooving-tool. Upon un.4
screwing the sleeve 10 slightly the needle may be removed 4or adjusted, and the tool 5 may b e turned to ad'ust its positionl or may behentirel y unscrewe and replacedwith an- Ot er. I
An important feature of the inve'ntion con-l sists in the fact that the diameter'of the sleeve 10 may-be made equal to that of the needle-bar, so as to form a continuation lthereof and permit the upper extremity Of the device to be drawn downl into the recess 2,' in
.which the needle-bar slides, as is necessary in the well-known Campbell straight-needle machine, there being no lateral prevent this. The shank of t e groovingtool is of ample dimensions toresist the' thrust of the tool against they work, and it is projection to securely xed'in place, being'tightl engaged t e taboth bythe clamping-sleeve and y pered extremity o the needle-bar. A si le operation serves to secure or loosen both t e needle andthe tool, and either of .these 'ma desired position indepen be turned .to the ently of the other. n
' Where in the claims the terms needle and needle-bar are used, these terms are not intended to preclude the-definition of the invention as vapplied to the. awland awl-bar,
to which the mvention `stances be applied.,
screw-threaded portions enga ingthe screwthreaded portions of the needle-bar and tool respective-ly and securing the tool on the needle-bar, substantially as described.
2. The combination, 1n a sewing-machine.,
.of a needle-bar, .a needle, .and a tool for operating upon the Work adjacent to the needle,v
and means for securing the needleand the tool. simultaneously on the needle-bar comprisingva rotatable sleeve forming .a continuaaving a screw- `threaded portion and a sleeve having two scribed.
,3; The combination, in a sewing-machine, of a needle-bar, provided with-.scwfthreads and with tapered needle-clamr ing jaws, a tool having ascrew-threadeds ank with a tapered recess, and -a sorew-threaded sleeve tion of the needle-bar, substantially as de- -shank and t e needle-bar so as to secure simultaneously the needle and the tool, substantially as described.
In testimony whereof I afiix in presence of two witnesses.
