EMBROIDERING-MACHINE.
Specication of Letters Patent.
Patented Aug. 16. A1910.
Application led Hay 4, 1909. SeraI'No. 583,916.
To all whom it may concern:
Be it known that l, Pi es ZND, a citizen of the Republic of Switzerland, residing at Gossau, near St. Gallen, Switzerland, have invented certain new and useful Improvements in Eiiihroidering-Machines; and I do hereby declare the following to be :i full, clear, and exact description of the invent-ion, Such :is will enable others skilled in the art to which it appertnins to make and use the same. reference being had to the accompanying drawings, and to letters or ligures of reference marked thereon, which form a part of this specification.
For the purpose of einhroidering with two or more differently colored yarns. -or with yarns of different strength :ind quality, shuttle machines have heen constructed each needle-bar of which has at least two rows of needles each capable of being'advanced to the piece of work and of being brought into oront of action as required.
T he disadvantage of such machines is that in bringing the one row of needles into the operative position the needles of this row come between the needles of the other row,
`which necessitates shifting of the work each time before the needles can ooiiinience to operate; furthermore a. separate shuttle is requisite for the needle of each row.
My invention relates to improvements in this type of machine, which l construct, in such manner that the rows of needles more simultaneously, so that when the one row is brought out of operation the other row is advanced into action; and the needles of thelatter row are slid exactly into that position which the needles of the former row occupied prior to their beim; retracted, only. a single shuttle being thus required for the needle of both rows. v
One Yorin of construction of the invention is'iiliistiatcd in the accompanying drawing, in whicli- Figure 1 is an elevation of a needle-bar of a shuttle cinbroidering machine having two rows of needles. F ig. 2 is a plan thereof', with the one needle row in the working position Fig. il is a like View with the other needle row in thc workingl position. Fig. 4 is a section on the line A-B of Fig. 2, and Fig. 5 is a section on the line C-D of Fig'. 2..ilwso two last. figurer; being drawn to a larger scale than the preceding ones.
l is the needle-hai' of a shuttle embroider- .ing machine, on which the needle niechan isms are. mounted, of which several can he arranged adjacent to each other along the needle-har. l'lach needle-mechaiiisni consists otl two superpoeed rails 2, 3, which can he slid up to the piece of work at s. Each rail 2, 3 carries a row of einbroidcringneedles 4. In the drawing only one coxnplete needle- inechanisin 2, 3 and a fragment of a second' one are illustrated. Each needle is secured to a project-ing tongue 2', 3 of the rails 2. 3 respectively, and the tongue: .2 ot' the rail 2 at the plat-e5 where the needles are fixed present elevated shoulders while the tongues: El' of the rail 3 present pendent shoulders G; these shoulders 5, 6 serve, as will he hereinafter explained, to limit the extent of inotionof the needle-rails.
For the purpose'of shifting the rails 2, 3 there, is employed a double-armed lever. pivoted to the needle-har l :ind whose divergent limbs 7.1% are furnished with longitudinal slots, in which there engage the pins 1) projecting from the rails 3. The rails 2. :i are also furnished with slots il, M iuclincd in o iposiie directions. The two rails are guided by means of pins 13. each of which passes through two super-porci'. slots ll. l2 and is screwed into thc needlehar l (Fig. 5). For tho purpose of lixing the rails 2. Il after the;Y have heen shifted, knohbed pins li are provided. `which cnn he inserted into holes 15. or lt in the two rails 2. Il respectively and into a hole. 17 in the needle-bar l.
in Fig. :2 the row of needles of the rail arranged for -inhroidering for instance with red thread. is lshown in the working position` while the row of needles of the rail 3 is ont of operation. that is to say retracted. the needle-points protruding but slightly heyond the front edge of the needlei har. lt' now it is desired to bring the needlerow of the rail 2 out of action and advance into the operative position the needle-row of the rail il. arranged for instance for embroiderin; f with white thread. the pins H must be \\'ithdr:iwn from the holes l5, 17 and the lover T. 9 must -hc turned in the direction o thc arrow (Fig. 2). The rail 3 will in this :'aiuicr hc shifted in the direction of thev slots l2. and at the saine time the rail 2 slid iii the direction of the slots ll, so that the needle-row of the rail IS will arrive in t-hc working position, while the nee/.llc-
i-nw ot' the rail 2 will recede ont or operl tion into the exact. operative position vaation. lirst needle-row (rail 2li will occupy exactlj, that position which the, other needle-row rail :2) has just. vacated. rVlie needle-row of the rail Il can now be tixed by insertion ot the pins 14 in the superposted holes l and 1T.
lf the needle-row ot' the rail 2 is. to he again advanced into the working positionv and the needle-row of the rail 3 retracted from the operative position. the pins 1-l lnnst be again withdrawn Jfrom the holes' lo, lT-and the lever S turned in the opposite direction to that shown by the arrow in Fig. :5. This will cause shifting of the rails in opposite directions to that above mentioned, the rail 3 with the needle-row being retracted and the needle-row of the rail 2 advanced into the working position. that is,
`into that. position which the needle-row ot the rail 3 has just vacated. The needlero\\' of the rail 2 must then he fixed in its. working position bj.' insertion of the pins H into the superposed holes l5. 17. That rail 2 or 3 which is retracted will butt with its shoulder 5 or (i respectively against that part of the other rail (which is in its operative position) that lies between two tongues f2 or 3', the extent of motion being thns restricted.
lfach of the other needle-meelianisms disposed on the needle-bar can he operated in the saine manner as that above described.
Vtith the new invention it will he seen that the einhroidery-frame has not to be. shifted on change of the needle-ro\\'s. and moreover one and the saine shuttle serres for the needle of both rows.
Having now particularly described and ascertainzal the nature of the said invention and in what manner the same is to he performed, l declare that what- I claim is:
l. In a shuttle embroidering machine, in combination.v a. needle-har, two snperposed sliding rails supported by the bar and each presenting a row of needles and. obliquely located slots, the slots of the one rail being directed in contrary direction to the slots of the other rail, pins projecting from the har, each pin engaging in a slot in each rail, and means for advancing the one rail toward the work while. simultaneously 'rctracting the other rail from said work, whereby the one needle-row can be brought in oblique, direcln this manner it. is obvious that the scribed.
cated by the other needle-row, substantially as described.
2. In a shuttle en'ibroidering machine, in combination, a. needle-bar, two superposed sliding rails supported by the bar and each presenting a row of needles and obliquely located slots, the slots of the one rail being directed in contrary direction t those of the other rail, pins projecting from the bar, each pin engaging in a slot in each rail, a double-armed lever pivoted to the bar and having slot-ted arms, and a pin project-ing from each rail and engaged by the one slotted arm, whereby on turning the lever the one can be. advanced toward the work while the other rail is simultaneously retracted from said work, substantially as de- 3. ln a shuttle emhroidering machine, in combination, a. needle-bar, two superposed sliding rails supported by the bar, and each presenting a row of needlesand obliquel)7 located slots, the slots of the one rail running in contrary direction to the slots of the other rail, pins projecting from the bar, each pin engaging in a slot; in each rail, Qmeans for advancing the one rail toward the Work while simultaneously retracting the other rail from said work, and means presented by each rail projecting into the path of travel of the other rail and limiting the extent of motion of the rail, substantially as described.
