'OVERSEAMING MACHINE.

"Application filed May l To all whom may 0072667471.

Be it known tha-t -1, JESSE JVHEAIYEL eitizen of the United States, residing at Nyaek, in the county 'of Roekland, State of New York, have invented eertain new and useful improvements in Overseaining Maehines, of which the followingis a deserip'tion, refe'ren'ce being had to "the accompanying drawi'ng and to the figures of re ference ni'a rked thereon.

The invention relates to new and *useftil improvements in over-seaming m aeh-ines, and more particularly to an over seaming machine ha ving a horizontally disposed needle for over-seaming fabric sections placed in a 'ver tie'al posit-ion.

object of 'the invention is to provide a inaehine "of "the above type with i'nea'ns for turning over the-edge portions of the fabric sections so that the ever-seaming stitches will stitch down said over turned portions.

A further object *of the invention is to provide'a machine of the abovety'pe wherein the edge portions are bothiturned over on to one faceof the fabric sections.

A still further I object of the invention is toprovide a machine of-the "abovetype with a supporting ineans over which the edge portions inay'he turned, and means for turning "the edge portions over the supporting inea ns, said supporting and turning ineans being disposed so "that the over seai'ning stitches will encircle the overturned edge 'p'or'tions er the fabi ie sections nstill ftir th'e'r" ohject of the nwentien ie to provide 'a inachine Ofthe ahoiie t'ype ith a sti'te'h finger which is located above 'the edge supporting and turnin 'p'ortions.

A still tur ther "obj eot of the invention is to provide a niaohine of the ah'ovetype with nieans for uncurling the edge portions'of'the fabric seetions prior to the feeding \(it the same to the edge supporting and turning devices.

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

In "the drawings which show by wayof illustration one embodiment of the invention Figure l is a side view of a portion'o'f a machine ei'nhodyingniy im rovements FigJQis a front view ofthesanIe;

Fig. 3 is a view partly in seetion and partly in plan showing-the feed cups a portion et the stitch fin'ger, the needle and the looper, the edge turning devices, and the uneu'rling devices ia'nd their relation to 'ieach other;

Fig. is .a View showing :partly in section and partly in plan, the needle and "the looper, the i uncurling devices, and the edge supporting end turning devices, and

Fig. 5 is a perspective View showing two "fabric sections and the devices for supporting and turning the edge portions ,of the fabric 'seetions.

The machine to whioh my i'nvention is applied is of the type known inthe artas a cup-deed machine, and I prefer to use a niztehine such as disclosed -"in"'the Fpatent "granted to Lansing Duderdo'nk, September -5, 11-916, No. l,l97g055,to whichjp'atent re-fer- Sene'e I may he had'ifor a :more thorough disiclosu re lot the over-seaming mechanism.

.The ma'ohi'ne is especially adapted for uniting the edge portions of chiffon hose or the like. Thehose are preferably knit 011 a circularknittingmachine, and are then split :in order to tacilitate the ap'plying-ot e1n broiclery thereto, after which the split, portions of 'the hose-"areic-onnected by =a seam. 'The present niachine is provided with means for uncurling these edge portions and directing the same to ithe stitching in'ech- 'anisnrwith the edge j por' tions side by "side and in Vertical fpositio'n. Between the 1111- ourlingf'devieje's a'ndithe isti tching meeha nism, Li's :ifinprevedp-inea'nepier turnin f;t'lie -edge ortionsr o'f' the if seeti'o'ns; Theseidevieeseons t t: herover whieh the ed e 'pot tfdns" on to 'lone' faeeotonefofthe fahri seetions. :A iturning member is i also provided for fol'd- 'i'n'g'over oriturning over said edge I portions. llhe supporting and turning means for the :edge portions of'the fabric sections is 'below the sheen finger and so i disposed relative to the needle that the oversea'ining "mechanism places "the over-seaming stitches about "the inturined portions. My improved. means can therefore be used for stitching these light mat rials and with an over seam of the usual width without any liability of: the stitches pulling out.

Referring unore in "detail to the drawings, '1 have shown my invention as-ap'plied to a sewing *ina'e'hine lraving a machine frame work 1 "carrying a bracket 2 in which is mounted an intermittently rotatable shattcarrying a feed wheel 0. The machine is also provided with a bracket i in which. is mounted a rotatable shaft carrying afeed wheel 5. These feed wheels 3 and 5 cooperate in feeding the material to the stitching mechanism, said material being held in a vertical position while it is being stitched by said feed wheels. The stitching mechanism includes a needle 6 and a thread carrying looper T. The looper is of the well known type used on cup-feed machines and is preierably operated by a mechanism such as disclosed in the O-nderdonk patent above referred to. The looper therefore mo es in to the needle thread loop on one side of the fabric sections and then across to the other side of the fabric sections where it is so positioned that. the needle will enter the looper thread loop, and then forms an overseani about the edges of the fabric sections. In 5 of the drawings, the two fabric sections to be united are indicated at and The needle threads are indicated at a and. the looper threads at Z. The two fabric sections 7 and f first pass through an uncurling device which consists of a central plate 8, on one side of which is an uncurling member 9 and on the other side of wl 'ch is an uncurling member 10. The uncurling member 9 is pivoted at 11 and a spring 12 normally presses the same against the central plate 8. 13 is limiting stop for the uncurling member 9. The uncurling member is pivoted at 1st and a spring 15 normally forces said uncurling member against the plate 8, and a stop 16 is provided for said uncurling member 10. As clearly shown in Fig. 41, the two fabric sections f and 7 pass between the respective uncurling members and the plate 8 and thus the edges are uncurled, as they approach the stitching mechanism. Rigidly secured to the uncurling member 9 is a supporting finger or. rod 1'1 Said supporting finger is provided with a loop portion 18 adapted to receive a screw 19 whereby said supporting finger is secured to the uncurling member 9. Said supporting finger extends forwardly and its extreme forward end 20 is parallel with the line of feed and of such a height that the edge portions of the fabric sections may be turned over said supporting finger. The edge portions are turned over said supporting finger by means of a rod 21. This rod 21 has a loop portion 22 and a screw 23 passing through said loop portion 22 secures the same to the uncurling member 10. The rod 21 is provided with a bent portion 23 at its forward end which extends over the supporting finger 1.7 and is so shaped and disposed relative to said supporting finger as to roll or turn the two edge portions of the fabric sections 7 and 7" over the supporting finger 17, as clearly shown in Figures a and 5. These supporting and turning devices are located beneath the stitch linger 24 over which the over-seaming stitches are formed, and they are also located between the needle path and the uncurling devices, and are furthermore so disposed relative to the feed wheels that the turned over edge portions will be encircled by the overseaming stitches. The needle passes through the fabric sections ad- .jacent the edges of the turned over edge of the parts may be made without departing I;

from the spirit of the invention as set forth in the appended claims.
