scams; '(Cl.112i--139) 4 This invention relates to an improved presser foot for sewing machines by means of which a hemcan be formed along one edge of a piece of cloth and one ormore cords or strings can be incorporated within the hem.

More specifically, it relates to a presser foot mechanism, adapted to take the place of the conventional presser foot on a sewing machine, and comprising a shield having a hole therethrough for the needle to penetrate, and having a member disposed below the shield provided with an eyelet or hole therethrough for the string, cord, and the like to pass. The ed e of the fabric is adapted to be folded around the eyelet member so that the hem will be formed with the string or cords therein. The eyelet member is pivoted so that when the presser bar of the sew ing machine is raised, the eyelet member will drop downwardly towards the bed plate Of the sewing machine so as to provide plenty of space between the shield and the eyelet member for the easy insertion of the strings through the eyelet in the eyelet member and also to facilitate the folding of the edge of the fabric therearound for the formation of the hem.

It is therefore an object of thi invention to provide a presser foot for sewing machines having a shield portion and having a pivoted eyelet member disposed below the shield portion, and around which the edge of a fabric is adapted to be folded prior to sewing the two layers of the fabric together to form a hem, said eyelet'memher having a, hole therethrough for the passage of cord, string, andthe like to be incorporated chine has a conventional head l2 having a vertically movable presser bar l3 and a vertically reciprocable needle bar M which is adapted to hold a needle l5. To the lower end of the presser bar l3, my invention is adapted to be secured. The invention comprises a top shield portion I6,

which is curved over and downwardlyas a1; l1.

This shield has an upstanding member l8, provided with a suitable slot 19 for the reception of asuitable screw or bolt 20, whereby the improved presser foot can be secured to the presser bar of the "machine. The shield l6 has an opening 2| through which, the needle is adapted to reciprocats in the sewing operation. In Figure 3, the

Figure 2 is an elevation looking at the front end of Figure 1, and omitting the bed plate;

Figure 3 is a top plan view of the attachment, omitting all portions of the sewing machine;

Figure 4 is an elevation looking at the rear side of Figure 1, but showing the needle in lowered needle opening 2| is shown somewhat closer to the cords in forming the hemthan in Figures 1 and 2. This is shown for the reason that the mechanism can be made as desired to provide the upstanding member I8 and opening 21 in any desired position in the shield to thus form the line of stitches any desired distance from the folded edge 32 of theiabric 21. Pivotally secured to the lower portion of the upstanding member is is an arm 22 which curves outwardly and around in front of the front edge of the shield I6, and hassecured thereto an eyelet member 23. The eyelet member has an eyelet 24 therethrough, through which suitable cords or strings 25 and 26 are adapted to be passed prior to a sewing operation. A piece of fabric 21 is adapted to be placed beneath the presser foot when the presser bar l3 has been raised upwardly, and this fabric is folded around the eyelet member 23, as shown in Figure 1. Then the presser bar I3 is lowered to sewing w position, and the machine is started to form a row of stitches 30 in the fabric to form the hem in the edge of the piece of fabric. It is seen by observing Figure 2 that when the presser bar I3 is raised vertically, that the eyelet member will fall downwardly toward the bed plate of the machine to provide additional space for the easy insertion of the fabric around the eyelet member 23, and also greater room is provided for inserting the strings 25 and 26 through eyelet 24.

Preferably the member 22 will rest against the top side of the shield l6 before the eyelet member touches the bed plate so as to thereby support the eyelet member a short distance above the bed plate when the presser bar i3 is in raised position, thus facilitating the insertion of the fabric 21 beneath the eyelet member and at the same time, enlarged space will be provided between the shield I6 andthe eyelet member 23 to permit the fabric to be brought up around the top of the eyelet member to a position as shown in Figure 1.

It is thus seen that I have provided a quickly attachable and detachable presser foot for sewing machines, which, on account of the pivoted eyelet member, provides easy access to the eyelet member and to the placing of the fabric beneath the shield and around the eyelet member prior to the sewing operation.

This invention can be employed in sewing continuous strips of material for the making of ordinary draw string tobacco bags, in which event the hem would be severed at the desired point to provide the desired width of tobacco bag, and

the draw strings would be pulled out through the severed portion to cut them to a longer length than the width of the piece of fabric from which the bag was made.

In the drawing and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. In a presser foot for a sewing machine having a presser bar for forming a hem in one edge of a fabric and incorporating in said hem one or more cords, comprising a substantially concavo-convex shield having its concave side facing the bed plate of the sewing machine and extending to a point in front of the needle bar and needle of the machine and having a hole therein for reception of the needle, said shield having a vertically disposed portion for attachment to the presser bar of the machine, said shield-having one edge extending downwardly in substantially vertical relation to the plane of the bed plate of the machine, an arm having its rear end pivoted for vertical swinging movement to the vertically disposed portion of the presser foot and extending forwardly and laterally of the shield and then inwardly towards the front edge of the shield, an eyelet member disposed beneath the front portion of the shield and being secured to the free end of the arm, said eyelet member having a hole therethrough extending from front to rear of the eyelet member for the passage of one or more cords, the fabric being adapted to be disposed below said eyelet member with one edge thereof folded over the top of the eyelet member so that a line of stitches formed by the needle of the sewing machine will secure the two layers of fabric together while the cord or cords are disposed between the fabric and the edge folded over the top of the eyelet member.

2. In a presser foot for a sewing machine having a presser bar and a vertically reciprocable needle for forming a line of stitches in a fabric, a shield extending forwardly from the Dresser bar and to a point in front of the needle, and having a hole therein through which the needle reciprocates, said shield having a concave lower surface, an arm pivotally secured at the rear of the shield on a horizontal pivot, and extending outwardly and forwardly and inwardly, an eyelet member secured to the free end of the arm and-disposed beneath thetforward edge of the shield for vertical swinging movement on said horizontal pivot, said eyelet member having a hole passing longitudinally therethrough for the passage of a cord, the fabric being adapted to be placed beneath the eyelet member and one edge folded on top of the eyelet member so that the line of stitches formed by the needle will pass through both plies of the fabric to incorporate the cord in a hem formed by the line of stitches.

3. In a sewing machine having a presser foot and a needle, said presser foot having inner and outer means for forming a hem in one edge of the fabric, the inner means around which the fabric is folded having a hole therethrough for the passage of a cord to be incorporated into the hem, the inner means being pivotally mounted on a horizontal pivot on the rear of the outer means for vertical movement independent of the outer means so that when the outer means of the presser foot is raised, the inner means will remain in lowered position to provide greater space between the two fold forming means for the insertion of the fabric around the inner means.
