chine-Lubricating,` Devices,. of which the following is a specification, re'terence being had therein to the accompanying' drawings.
This invention 'relates'ito anV improvement needle; and it is designed more particularly for employment in machines adapted to Sew heavy or coarse material of such nature that 'considerable friction is created by the pas- Sage ot the needle therethrough. ln such machines it is desirable to maintain a filmo't lubricant between the 'surface of the needle-blade and Vthe material during the scivin'g operations; and ltheprese'nt invention is desig'i'iedlto conduct a measured quantity of lubricant to' theneedle" and to distributie 'such lubricant over the surface thereof Without attention on the part of the sewing' inachine operator, other than the maintenance o'. a supply of lubricant in a suitablereservoir mounted upon the traine ol the machine.
with a. tubular conduit which conducts the lubricant to an annular chamber formed in a bushing mounted within the head of the sewing machine `=traine. The bushino' serves as a lower bearing` v4tor the reciprocating needlebar, und the'latter 'forms the inner Wall of the annular chamber. The needleba'rsisborediout axially to vforni a conduit ttor the lubricant, and is provided with an aperture or port, which, duriiig'tlie reciproeation ot said needle-bar, comes into and out ot register with the tubular conduit leading' :trom the reservoir. Thus the lubricant is permitted to loiv 'from the reservoir into the needle-bar at intermittent periods duringl the reeiprocation ot the latter, The lower end of the needle-bar is prov'uled with a. needle shank cavity, is threaded and 'formed lwith a slit, to provide a clamping;` member for the'needle-shanlr, its coaeting member being a clamping init. The lubricant passes through the axial cavity or conlower end o't eaid bai; thence tliii'ong'h the slit in the latter which extends above `the shank et the rllhe devicecomprises a reservoir provided l l l needle, and thence over the beveled clamping; nut to the needle-bar ln the accompanying; dra wings.y liin'ure l is a .side elevation ofthe device as applied to a Singer machine ilor sewing bags, the iframe of such machine being shown in dotted lines. lfig'. 2 is an end elevation par tiallzy .iu'section' showing' the needle-har in its extreme lower positioin the needle-bar port being' closed. Fig. 3 is a detail vieiv in section showing the needle-bar in an intcrniediate position", the needle-bar port being open. Fig. l a detail vieu' in section showing the needle-liar' in its extreme upper position, the needle-bnr port heini; claalied.. Fin'. is a-delta'il View of the lower portion ot the needlevbar showing" vone olf the lubri- :ant ducts from which the lubricant passes to the needle.
As herein represented1 the device is applied to a sewing` machine in which reciprocating movenients are imparted to the neeK dle-bar l byfdi'iving-Qhaft through the' crank-arm 'lfand link said dl'vine'rhlmlft being mounted within the overhanging arm lB ol airframe A. .Uponthe over-hanging arm B .is mounted a lubricant reserroir'. which may be ot any suitable form. ln this instance the reservoir is provided with downwardly extending' lugs or ileet .3* havin;` openings tor the passage ot screws G by. which the reservoir is overlianginel arm B.. The loiver Yall of the :reservoir isprovided with an opening' to receive tubular conduit 7 by which the lubricant is conducted to -an annular chamber 8X ilorined in a bushingn 8 mounted Within the head C of overhangjing arial?) ot the trame.
The bushing' S serves as the lower bearingr member lor the reciprocating needle-bar l7 and the. needle-bar forms the inner Wall oit Said lubricant chamber SX. It willl be `seen that annular chamber SX serves to distribute luln'icant around the outer tace of the needie-bain and thus to lubriczlte said bar in its movements Within bushing` S.
rllhe needle-bar is bored out axially, to provide a' cavity or 'conduit 1X into which the secured to the lubricant is permitted to loW when the needlf'f--bar port 9 comes into register with annular chamber 8X and tubular conduit 7.'
ln 'the present instai'ice the port v9 is so located as to come into register with the 'tubu lar conduit T tor :i briet1 period both during the riee andv the descent oit the needlefbar,`
-' bricant'williowfrom the ducts to Ylubri- -cate-the threadin addition to the needle.
l .The -cavity or conduit 1X^of the needle-barv Y lateral opening l2 passes through the lubri-` l5- 13 and'needle-bar port 9 are so proportioned such case the'lubricant as it graduallypasses 'from the needle-bar through ducts 13 is re-lv placed bythe iiow of lubricant from reser- -a lateraljopening or slit ,12 Which extends j through .the 'needle-bar. The needle-cavity `or ystop lxis provided against which the vided at opposite sides of. the. needle-bar 'tiif'ely proportioned thatneedle-bar cavity lX `storing a supply ot lubricant said port being closed when the needle i'sl Withdrawn from the Work.
1 registers-with a reducedlubricant passage 10 iormedvln said bar, which passagecornmuni'cates with a needle-cavity 11 andWith 'slightly' greater in diameter than lubricant passage 10 so that an annular shoulder shank end of the needle abuts when it is clamped in the needle-bar.V inasmuch as cant passage 10 at a point slightly above shoulder 11X, two lubricant ducts 13 are pro` through which the lubricant` .passes to beveled clamping-nut 14 which serves to secure the shank ofthe needle 15 Within n eedle cavity 11.
In the present instance the lubricant duct-s in Vsize that lcavity 1 of the needle-bar acts merely as a vconduit for the lubricant. However, said ducts and port may be so relainay serve as an auxiliary reservoir. In
voir 5 through port '9, as will be understood Without furtherexplanation. It-Will also' be understood that the ducts 13 and port 9 may be smproportio'n'ed that sufhcient lu.-
The lubricant reservoir may be of any desired.' form and located lat any' suitable point,
it being necessary only to provide means'for l preliminary to' itspassage into the needle-ba 'Having thus'set forth thelnature oftheinvention, what I claim herein is 1.]In a lubricating device orsewing machines, a lubricant receptacle, a lubricant two` subscribing Witnesses.
2. In a lubricating device for sewing ma` l' chines, a lubricant 'recept-acle, a' lubricant conduit leading from said receptacle and inhiding a chambered needle-bar, a needle leading, from the needle-bari to said needle,
and means including said needle-bar forvv .controlling the iowro lubricant through said conduit'. v
3. In a'lubricating device for sewing -inachines, a lubricant receptacle, ia needle-bar, a conduit adapted -to conduct lubricant from said receptacle vto the needle-bar, a chamber formed insaid needle-bar,l a port entering said chamber and intermittently registering with said conduit during the reciprocation of the-`needlebar,'and a lubricant duct leading `frcm'said chamber toa needle supported -by said needle-bar.A
f 4. In aV lubricating" device. for sewingmachines, a frame and a lubricant receptacle supported thereby, a needle-bar and a bear-y ing member therefor, a chamber formed in said needle-bar, a port entering said chamber, a 'lubricant conduitleading from Athe receptacle' an annular 'chamber formed in said bearing'member and communicating with said conduit, and a lubricant duct lead.-
carried by said needle-bane lubricant duct ing from the chamber formed in said needlebar to a needle supported by said bar.
