To all whom it ymay concern.:
Be it known that I, LANSING ,Onninnonm e `citizen of the United States, residing et New York city, in the county oi New York,
State of New York, have invented. certain This invention relates to what is known es v n zie zag stitch sewing machine,
The objects of the invention ere, first, to provide it machine of this class with two independent needle bars, having means for imN parting independent bodilynorizontel movement to thm in addition to the ineens which imparts the simultaneous ve r tical movement, and second, to provide in such e machine means for varying or adjusting the seid independent bodily horizontal movement of' the needle bers in order to vary the width. of the stitches and produce widely dii'l'ering patterns of stitches for ornamental and seeming purposes. These objects l accomplish hy the meclnmism illustrated in the eccompsi'iying dm ings, in which Figure 1 is :1y front elevation with the work plete broken away to show the looper sind feed meelninism; Fig. 2 is e. horizontal section on line 2-2 ol Fig. l; Fig. is o. flete-il enlergod horizon tel section of the inside needle her carrier, its exis and a portion ol' the con meeting rod; Fig. 4 is it transverse vertical sci-tion on lineAM-Jf ol` Fig. l, looking to the righi; Fig. 5 isnn end elevnlion of the heedend ol` the machine; l? ig. (i is :in enlarged perspeci'ivo of' the needle artnet ing mechenisnn.
remoif'ed from the machine freine with the needle bnr carrier separated ior cleernoss; ll ig. T is im enlarged detail perspective showing the connect ions between one oi the needle bor carriers and iis Connecting rod, Figs. 7' and 7b ere 'perspectives of other forms oi`-11eedle vibre-l ing com nieclmnism; ond 8 to 20 represent some of the many patterns ot stitches iormed'by this machine.
A desigmttes the bed of the machine freine, A the goose neck, A2 the head thereof, A the worl; plete, B the mein shaft, C the needle erm, C the connecting rod, which ectinttes the loopers D, and E is the eeddog, end E its rocker. These parts, together with the w presserv bar F, its foot Il and hiting com (I are ell shown `in the prior machines of the Union Special "ype end need not therefore be further described.
H, I, designate two independent horizontelly swinging needle ber carriers pivoted loosely on 'e common vertical exis H2 et the rear et the heed A2 by Ineens of epertured eers it 'i respectively, and extending forwardly et o posite sides or the presser foot bar F, to the ont of the heed A2, where they are provided with needle guiding eyes h t" in which the two needle bers H I ere reciprocated vertically from the needle arm C, to which they are pivotelly connected by Ineens of two links c c; a. screw c3 extending through e. slot c2 in the link c into the link c/ to allow the necesser-y independent oscillation of the links, while connecting them. f
The needle vibrating mechanism comprises e vertical shaft J mounted to vibrate or rock horizontally in e bearing A4 mounted on the goose neck standard, and provided at its lower end with a crank erm J having a swveled forked block J2, extending down into grooves 1f formed in the periphery of e cem wheel or disk K mounted on the mein shaft B. The com grooves 7c ere parallel and straight except et the switch 7c where they cross over ond impart the rocking movement to said crank shaft; the shaft being held stef tionery except when. the switch rocks it eltern etelylin opposite directions.
rihe upper end oi the rock shaft J is provided. with o transverse head heving'upper and lower connected curved slotted plates or bers J3, J4, in which are clamped odjustobiy the blocks j", to which the right hand ends of the two connecting' rods J", J0, are pivotcd. The lett .hemd lends of these rods J", J, :rre pivolnliy end adjustebly connected to lugs ft2, it, on the lfree edges of the needle ber cerriers li, l., so as. to vibrate the carriers and with them the two needles bodily in opposite directions et stated interwils. This adjustahle connection comprises eccentric adjustin blocks ja through which clamping screws j extend into the lugs i and h2 to bind seid blocks together. These blocks js are each provided with si linger piece j 1 by which they ine-y be turned upon. loosening the screws j". The rods Ji', L, ere each provided with a strep j which turns on the blocks jsend therefore when the screws are loosened the eccentric blocks or either of them may be ltermines rst, the amount of lateral throwto le and 18, Fig. 13 shows bar carriers H and I and brin their needle bars and needles into or out of line with each' other. The throw of these needle bar carriers is effected by adjusting the blocks js, f4 in the curvedA arms J 3, J 4.
By adjusting the eccentric blocks js and the blocks ja, 7'4 I am enabled to vary the pattern of the stitches as shown in Figs. S to 20. For instance, when the` needle bar carriers and the needle bars carried thereby are adjusted by the eccentric. adjusting blocks js to bring the needles in line with'each other, the stitch of one needle will follow in the path of the other and therefore cause one stitch to overlie the other as shown in Figs. 8, 12, 13 and 17 without regard to the adjustment of the block 7'3 j4. If, however, these eccentrics js are so adjusted as to bring the needle bars out of line from front to rear, then the lines of stitches will be more or less like those shown in Fi s.9,10,11,14,15,16,18, 19 and The a justment of the blocks 7'3, 7'4 debe given the needle bars and being independent of each other, one may be adjusted t0- Wards or from the axis 'of the slotted arms J3, J 4, a greater or less distance than the other and so one needle bar will be given a greater or less throw than the other and so the zig zag of its stitch will be greater or less than that of the other. Such differences in the zig zag being shown in Figs. 10, 11, 12, 13, the stitching where the needle bars are in line and one adjusting "tric adjusting blocks js.
block y`3 is on the dead center and so causing the needle to stitch on a straight line, While Fig. 14 shows over Fig. 13, the effect of changing the adjustment of one of the eccen- YVhen the adjusting blocksj, jt, are both at the same side of the aXis of the slotted arms J3, J4, the pointsof the stitches will eltend iii the same direction, as shown in Figs.,10, 11, 18 and 20,.but when said blocks are at opposite sides of said axis then the points of the stitches i 7ill project in Opposite directions, as shown in Figs. 8, 9, 12,
' 15, 16, 17 and 19.
:the'two lines of stitches interlock, would be j very desirable in vmaking abutting seams.
In Fig. 7a, cani K, a horizontally turning cam K4 provided in its upper face with a'y cam groove ,t4 into which extends a roller fc5 mounted on the crank arm J of the vertical needle bar carriers operating rock shaft J andthis cam K4 is secured to or formed on the upper face of a gear M j ournaled on the bed A and in mesh with a pinion M on the main shaft. This cam needle bars into and shaft, a needle I employ in lieu ofthe switch K4 is timed to rock the shaft J in like manner to the cam K before described ythe Asmall pinion M rotating twice to one rot'agion of the gear M.
In Fig. 7b, which shows my preferred form, the cam K5 is mounted on the upper face of the gear M and is strad dled by a forked crank arm Jlo, having a split at the base of its fork and there provided with a screw J to draw the arms of the fork together and take up vean Y Y these several cam mechanisms the parts are so timed and shaped that the needle bar carriersH, I, will be vibrated only when the needles are to be moved bodily in a lateral direction.
The loop taking and feed mechanisms coe operate with the needles in the same manner as in other Union Special machines.
