RUSSEL G. WOODWAR-D, OF CHICAGO, ILLINOIS, ASSIGNOR- TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

EDGING-GUIDE FOR SEWING-MACHINES.

Application filed August 6, 1909.

To all 71']! out it may concern Be it known that 1, Russian G. \VoonwAnn, a "citizen of the United statesi'esiding at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Edging-Guides for Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in edging guides, and more especially guides for edgings which are provided with diagonally extending cross bars.

An object of the invention is to provide a guiding device which will spread out the edging and properly position the cross bars relative to one another, so that when the edging is fed to a stitch-forming mechanism, it may be properly secured to a fabric.

. A further object of the invention is to provide an edging guide which may" be used to direct an edging to the under face of a fabric, spreading out the edging and properly position the cross bars thereof.

A further object of the invention is to provide an edging guide which may be readily withdrawn from the position adja-- cent the stitching mechanism, so that the same may be thrnided with the edging.

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

In the drawings which show by Way of illustration, one embodiment of the invention,-

Figure 1 is a front view of the forward portion of a sewing machine having my improved edging guide attached thereto; Fig. 2is a transverse sectional view through the work support and edging guide, the feedoperating mechanism and loopermechanism being omitted for the sake of clearness; Fig. 3 is a plan view of a portion of the work support, showing the relation of the edging guide to the feed and the-stitching mechanism; Fig. 4 is a similar view with the cover plate for the edging guide removed; Fig. 5 is a view from the front of the edging guide, showing the saline detached from the machine; Fig. (5 is a top plan view of the edging guide, spreading the edging and positioning the Specification of Letters Patent.

cross bars; Fig. 7 is a detail, showing the position of the needles and the loopers 00- operating therewith; Fig. 8 is a detail, showing a section of the fabric with the edging stitched thereto.

The sewing machine, as herein illustrated, may be of any desired construction, and ,6,0 forms no part of the present invention.

1 have shown a work support 1, an overhanging arm 2, a needle bar 3 carrying nee dies at, 5 and 6. The needle bar is reciprocated in the usual manner by the needle lever 7. The presscr foot 8 is carried by the presser bar 9, and may be of any desired construction.

The work support 1 has the usual depending apron 10, and said work support is carried by the bed plate 11. The feed dog 12 may be of the ordinary four motion type, and is provided with fabric-engaging surfaces 13. An auxiliary feed dog 11, which has a dilferential movement relative to the main feed dog, may also be used, if desired. These .parts are of the usual construction, and will not need further description.

In making garments, it is often desired to provide the same along the edge or sometimes in the body thereof, with an edging which has cross bars underneath which a ribbon may be inserted, or through which a ribbon may be threaded. For example, in the necking of underwear, it is desirable to provide the neck portion ofthe garment with an edging of the above character. My

invention is directed to a guiding device which will guide an edging of this character to a stitching mechanism. It is sometimes desirable to stitch the edging on the under face of the garment, and it is also sometimes desirable to stitch the edging on the upper face of the garment. As herein illustrated, I have shown a guiding device for guiding an edging so that the same may be stitched to the under face of the garment. It willv be understood, however, that the edging guide may be disposed above the fabric and operate to guide an edging t0 the upper face of the fabric. Y

My improved edging guidecomprises spaced plates 15 and 16, which are held separated by spacing bars 17, 17.

As herein shown, the work support is cut away as at 19, to receive my edging guide.

The edging guide is pivotally mounted on a bracket 20, which is secured to the depending apron of the work support by suitable screws 21. A pivot bolt extends through ears bent up from the bracket 20, and the side members and 16 of the edging guide. The side members 15 and 16 are provided with inwardly projecting parts which extend to a point in front of and adjacent the needle slots 21 in the throat plate. The needle slots 21 are adapted to receive the needles 5 and 6, and the needle slot 25 receives the needle 4:.

The inwardly projecting portions of the members 15 and 16 are provided with cross bars 26, J, 28, 29 and 30. The crossbar 26 on its upper face has an upwardly projecting curved portion 31, which terminates in recesses 32, The cross bar 527 has a similarly curved portion 33, which projects downwardly. The cross bars 28 and 30 have curved portions 31 projecting upwardly; while the cross bar 29 has a curved portion projecting downwardly.

The curved portion of the cross bar 28 is formed on a slightly larger radius than the curved portion of the cross bar '26, and the recesses 32, in which the curved portion terminates, are arranged slightly closer to 30 the side bars 15 and 16. The curved portlon of the cross bar 30 is formed on a slightly larger radius that the curved portion of the cross bar 28, and the recesses 32 of the cross bar 30 are still a little closer to the side mem- 35 bers 15 and 16.

The curvature of the cross bar 2 slightly greater than that of the cross bar 26, and sligthly less than that of the cross bar 28; while the curvature of the cross bar 29 :28, and slightly less than that of the cross bar 30.

The edging 3%, as shown in Fig. 8, comprises side portions 35 and diagonally arranged cross bars 35. In guiding this edging to the stitch-forming mechanism, it is led over the cross bar 26; underneath the cross bar 27 over the cross bar 28; under the cross bar 29 and over the cross bar 30, as shown in Fig. 2, so that as the edging is drawn through the guide, the same will be presented to the curved faces of the cross bars. This edging, as it comes from the roll is very much distorted, and drawn together. 55 As it passes over the cross bar 26, the curved portion will crowd the side parts 85 of the edging down into the recessesBQ, and separate slightly said side portions of the edging. The cross bars as they pass over the curved portions will also be put under ten sion, and will assume their proper position diagonally of the side portion of the edging.

As the edging continues over the varying curved surfaces and the varying width slots 35 32, it will be properly spread and the cross is slightly greater than that of the cross bar barswill be properly positioned,so that as the edging leaves the guiding device, it is properly shaped to be secured to the fabric.

A cover plate 37 is secured to the work support 1 by a slot and screw connection 38. This cover plate extends over the edging guide, and will serve as a rest on which to guide a body fabric, to which the edging to be stitched. Said cover plate may, if desired, be provided with an edge guide 30 for guiding the edge of the material.

As herein illustrated, I have shown my stitch-forming mechanism as provided with needles 5 and 6. These needles are so located that one edge of the edging will pass underncath the fabric between said needles, so that one of the needles will enter the edging and the other pass at one side thereof.

Cooperating with the needles 5 and (3 is a looped 40, which will lay cross threads -.1-l across the edge of the edging, as shown in Fig. 8. The needle 4 is so positioned as to pass through one of the side members ot' the edging, and a looper i2 cooperates there-- with to secure the edging to the fabric.

l/Vhen it is desired to thread the edging into the guide, the cover plate may be removed and the guide swung about its pivotal support 22, so that the edging may be readily inserted, after which the guide is swung back to its normal position and the cover plate replaced.

While I have shown my edging guide so disposed as to guide an edging to the under face of the fabric, it is evident, as above noted. that said edging guide may be supported above the work support and guide an edging to the upper face of the fabric.

The inwardly projecting side members 15 and 16 are gradually narrower as they approach the stitching point, thus forming a tapering lower face 23. The ends of the side members adjacent the stitching point are merely the width of the side bar 30. By this construction I have provided a clearance for the looper mechanism an am able to bring my edge guide very close to the stitching point- Having thus described my invention,
