The invention consists in a prcsser foot which has a supporting shankon which are yicldingly mounted two main foot sections arranged side by side. Between these sections is a third yicldingly mounted section which is located wholly in rear of the needles so as to engage the enchained loops for chaining oil when fabric sot-Hons are passing underneath the presscr foot. The two main sections, in front of this intermediate chaining-01f section, meet in a line passing between the limits of the stitching mechanism which preferably includes spaced needles so that two fabric sections may have their edges abutted and joined by the stitching mechanism.

cfcrring more in detail to the drawings, the presscr foot consists of a supporting Fig. 4 is a top plan view of the prcsser shank 1 having a recess 2 formed therein for foot with the strip deflector turned to one receiving the prcsser bar 3.

e invention relates to new and useful improvements in a presser foot for sewing machines, and more particularly to a presser foot having a plurality of foot sections adapted to engage the fabric being stitched.

An object of the invention is to provide a presser foot havin a shank and main foot sections arranged side by side, which sections are so supported by the shank that one of said sections may move bodily vertically relative to the other, with an auxiliary foot section located inter into said main foot a similar view showing the extra sections, together with means Ipassing under the left hand oot; and

view, similar to Fig. 5, but

of the infor supporting said auxiliary foot section whereby the same may move bodily vertically relative to the main foot sections, said auxiliary foot section being so disposed as to engage the enehained thread 100 extending from a stitched article for c ainin olf when fabric sections are Passing bencati the front ends of the main oot sections of the prcsser foot.

A further object of the invention is to p vide a presser foot of the ab ve character with an auxiliafiy foot sectiot? which 1s located wholly i'h rear of the needles.

These and. other objects will in part be obvious and will in part be hereinafter more fully described.

In the drawings Figure 1 is a perspectiye view of a resscr foot embodying the invention and with the st?!) deflector thrown to one side;

Said foot section 5 is mount- Fig. 6 is a perspective view of the intered so as to move bodily vertically relative mediate ieldmg sections for engaging the to the supporting shank 1. Said section is enchained loops for chaining oif; formed with a standard 6, see Fig. 5, which the front end ofv freel slides in a recess 7 formed in the shun 1. 'At the upper end of the standard there is a head 8 which has a threaded connection with the standard 6. This head 8 is slightly larger than the standard 6 and is adapted to enga e a shoulder 9 formed in the upper end 0 the recess 7, to limit the downward movement of the section 5 of the presser foot. A spring 10 is secured to the shank 1 of the presser foot by a suitable screw 11 and this sprin bears on the upper end of the head 8 an resses the section downwardly until the liead engages the shoulder 9, when the presser foot is raised from the work support.

There is a main' foot section 12 which is also bodily movable vertically and yieldingly supported tion 12 is formed with an upwardly extending standard 13, see Fig. 5. This standard slides in a recess formed in the side face of the shank 1, and said standard is held in place by' a cap plate 14, which covers said recess and is secured to. the shank 1 by screws 15.

The standard 13 is slotted, as indicated in dotted lines in Fig. 5. and a screw 16 passing through the slot into the shank limits the downward movement of the foot section 12. A spring 17 is secured to the shank of the presser. foot bv a suitable screw and,

when the foot is lifted, this spring bears against the upper end of the standard-13, and when the foot is lifted it forces'the standard downwardly until the upper wall of the slot engages the screw 16. The n ward mo ement of each of the foot sccti 5 and 12 is limited by the respective foot section engaging the bottom of the shank 1. The downward movement of these sections is limited by the means above described when the presser foot as a whole is raised from the fabric.

The foot sections 5 and, 12 in the presentembodiment. of the invention are arranged side. by side and are conjointly prov'ilcd with needle slots 18 audit). The to. sections meet in a line passing throufrh these needle slots. Projeetinginto the needle slot 18 is a stitch .fingcr20. The greater portion of this stitch finger is carried by the. foot section 5. Proicetil-ig into the nee: lc slot 19 is a stitch finger 21 and practical ly the whole of this stitch finger is carried by the section 12. he foot section 5 in rear of the. tongue 20 iaatso provided with ,titwrv-ed projecting fingert 21" which overitijzis the meeting line between thp sections andffor'ms the rear wall of tlienaedle slot 18.

Intermediate the nmin foot sections Iiahd 12 is a yieldable gl't xiliary foot scctio 22. The-inner faces ,0 I the main foot secti he 5 and 12 are respectively formed withfyopposed recesses 23 and 2-1. see Fig. 2. and the intermediate or auxiliary foot section 22 is 12. Said shank 26 is cured to the shank screw 29, see Fig. 9, rests on the upper end by the shank 1. Said sec-' needle slots 18 and located in these opposed recesses. It will be clear from Figs. 2 and 9 of the drowin that this foot section 22 is located entir in rear of the needle slots 18 and 19 an therefore, entirely in rear of the needles. The foot section 22 has its front end tapered off at 25. This foot section is carried by a standard 26 which slides in the same recess as the standard 13 of the main foot section formed with a slot 27 through which the shank of the screw 16 passes, and this slot limits the downward movement of the section 22. A spring 28 seof the presser foot by a of'the shank 26 and normally forces the foot section 22 downwardly when the presser foot shank is raised. As shown in the drawings, the presser foot is especially adapted for a sewing machine having a cylindrical work support 30 and wherein the position of the presser foot and the feed 'is such that the materials being stitched are fed off the arm of the machine. A trimming mechanism including a stationary trimming blade 31 and a reciprocating blade 32 may opcrate upon the edges to be joined and in advance of the stitching mechanism. The sta tionary blade is carried by the presser foot and the movable blade operates in a recess 32' in the upper face of the presser foot. The trimmed ofl' stripis deflected to one side (tithe-stitching mechanism by a strip deflcct'or 33 which is preferably pivoted to the presser' foot so that it may be turned to one side to give access to the. needles for threadinan, This trimmer mechanism and the strip deflector form no part of the. present invention. a

With the presser foot constructed with 19. a stitching mechanism may be used having a pair of needles 34. 34, which enter the needle slot 18. and also'a pair of needles 35. 35, which enter the needle slot 19. The outer needles determine the limits of thestitching mechanism and the meeting edges of the foot tions 5 and 12 are located in a line pas nf: tween the limits of the stitching mechanism.

As shown in Figs. 10 and 11, the csser foot is espccinlly adapted for the of two fabric sections one of whiehas of a single thickness while the other is of a double thickness. as for cxtinple, in .the. stitching of a folded collaret c strip to the hodyportijon of an triucut.
