EDGE-GUIDE AND STITCH-FINGER F O BSEWING -M APHINES.

To all whom, it may concern: Be it known that I, RUSBEL G. Woo- WARD, a citizen of the United States, residing at lVaukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Edge-Guides and Stitch-Fingers for Sewing-Machines of which the following is a description, -re erence beinghad to the accompanying drawing and to the letters and figures of reference. marked thereon.

h'ly invention relates to improvements in sewing machines, and-has for its objects to provide an edge guide and stitch finger, which are simultaneously adjustable in a direction at an angle to the line of feed.

Myinvention consists in the novel parts o l and improvements hereinafter shown and described.

In the accompanying drawing :-Figure'1 shows in plan, a throat plate provided -with my edge guid'eand stitch finger, and also the relation of the same to the elements of an overedge stitching machine. Fig. 2 a side elevation of my improved edge guide and stitch finger. Fig. 3 is a sectional view.

taken on the line 3, 3 of the throat plate shown in Fig. -1.-Fig.- 4 shows in perspec-'- tive, a throat plate with my improvements attached thereto. E 3

in the drawings, the throat plate 1 is 'prorided with slots-2', 3, an d 4, through'which operates the feed dog to move-thepfabrio. 'lhe direction-of feed is longitudinal of the threat plate-*as-yiewed; in Fig 1. The threat plate is 'provided with-a recess 5, 1n

which is adjust-ably mounted a plate car-- rying an edge guide -7. 'Tliis plate is secured in its adjusted positions, by screws 8,;

S.- -As shownin the-drawings, the edge guide is torined;; integral with the adjustable plate. It--'\i'ill,}%lfj$veve1',,' be observed that said guidemay iie htta'chccl to thc'plate in A.

- anyother-manner.

In the presentembodiment-of my inven t'ron, the stitch-finger is formed by ta'p'ering the rearward portion of the edge guide,

that portion "extendingtoward the needle,

team in reality,- -'fthe-, edge guidej'and'stitch firf er form one continuous 'member .f- In orfer to support the .=rearwa1 t1'- end of theetlge guide and stitch fingenmore firmly, I,

- have provided 'a laterally extending lug 10,

which is seated in.a recess 11 inthe throat plate. Extending rearwardly from the lug .Iieedle,= whereb thaedge1of. the material is d Specification of Letters Ifatent. Patented Aug; 26,1913. Application filed December 6, 1906. Serial No. 846,573.

10, to a point adjacent the'rearward eiid of. the stitch finger is a ledge 12, which serves to support the outer edge of tlie fab'ric'at,

the point of sti'tchi'n The needle 1.14:. passes through the material and enters theo enin formed between the ledge 12 and t e wal 13 of the throat late. Coiiperating with said needle, are t e elements of an overedgestitch. mechanism, which as illustrated in the 'dra'win s, consists of a loop spreader 14, and a t read carrying looper 15. The loop spreader takes the loop from the needle beneath thefabric, c'arryin the same into the" path of vtnovenient o the thread carrying Iotiper :which passes through said needle loo and carries its own loop into thejpathof t "e descendihg needle,

thus-forming stitches around 'gtheedge of the fabric, and... over the stitch finger' 9. The

feed oi the fabric carries the stitches in the usual .inanner off the stitch finger. The

stitch finger as shown in the drawing, there-" 7 f ore, extends across the plane'o'f the fabricand serves-also .asfan' edge'guide; When it is desired to adjust the widt-h of th overctlg'e stitch,'- the screws" 8f are loosened and 1 the that by making the guide and'tongue of the throat. ,plate-'integral'f tliiit I; am able to properlycontrol the edgeof the; goods from the-front oigthe guide to 'thes't'itching point .or=;.where the? threads a'r'e'lapped over the edge of the goodsc lnasmuch as' the edge guide-extends well'to t-h'efro' t of the stitching point, the looseends of...' l rea'ils will be turned up and the cut-edge properly directed .-.t0 the stitching mechanism so that said :t; s increasing of the 0?.. ledge stitch. It will thus be seen edge will; be covered by tlie oi eredge stitches.

Having thusdescribed myinvention, what "I claim as new and desire tosccure hyLetter's Patent is -1.-'.The combination of a needle, awoi'lr idly carried; thereby, said edge guide am sup ort haying, teed slots ,tlierciu, 'a'nd a com 'ined-i edge 'guidBjJa'n'd Fs'titch'; finger rig.

guidediintil a e'r-the same ls-coi'ered with the stitches, said edgeguide having a work support having feed slots therein, and acomblned edge guide and stitch, finger rigidly carried thereby, said edge gui'de. and

stitch finger having an edge guiding portion extending rearwardly-vjto a point beyond the" needle, whereby the edge of the material is guided until after the same is covered with the's'titches, said edge guide having a work supporting-ledge projecting laterally therefrom toward the needle, the upper face of the ledge lying substantially in'the plane of the work support, whereby the edge of the material is supported and guided as it passes the needle,', and means-for adjusting-said edge guide and stitch finger relative to the needle.

3. In an overedge stitching machine, the

combination ofi. a throatplate, an edge guide, a stitch finger carried thereby, an

adjustable plate supporting said edge guide, and a supporting lug, extendin from .the

rearward end of'said'edge gui e and engaging the throat plate.

4:. An overedge stitching machine including in combination, a throat plate, a stitchcombination of a, throat plate, an edge guide, an adjustable plate supporting said edge guide, and a supporting lug, extending from the rearward end of said edge guide and engaging the throat plate.

in testimony whereof I afiiir my signature, in presence oftwo witnesses.
