To all whom it may concern:

Be it known that I, WILLIAM Giesen, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Open-Welt Guides, of which the following 'is av specification. l

This invention relates to 'attachments for sewing'machines and particularly to attachments for producing openwelt seams on garments.

Some of the objects of my im roveme'nt are, simplicity of construction, vEewness of parts, cheapness of manufacture, ease and rapidity of adjustment, ease of attachment,

, perspective view o ease of adjustment. for welt seams of differ- 'ent widths, accessibility, strength, and durability. These objects I attain by means of the device illustrated in the accompanying drawings in' which-- :Figure 1 is a pers ective View; Fig. 2, a the attachment-bar; Fig. 3, a. perspective view of the guide-foot; Fig. 4, a perspective view of the guide-shoe; Fig. 5, a detail sectional View; and, Fig. 6, a sectional view of an open welt.

Similar reference numerals refer to similar parts throughout the severalviews of the drawings.

The sewing machine head 1, and the bed: plate 2.,.may be of the conventional form. Likewise the foot 3, the needle 4, and the feed 5, may he of the f rm found on any of the sewing machines no 'in use. An attachnient bar 'is provided,-' having a slot at one end and u square tenon, ,adapted to attach to the head 1 of a sewing machine at the opposite end. The attachment may be accomplished by means of a screw 7.` A leg 9extends downward from bar 6, which supports at its lower endan integral guide-foot 8 and is 'provided witha square mortise v in its upper ond, adapted to slip over and fit the tenon of bar 6. The guide'foot 8 consists of a piece of sheet metal bent to form a 'right angle, having its free-end in a plane parallel with the base-plate 2 of the sewing machine. A guide-shoe 10 is provided, having a horizontal slot 11 formedin one of its ends, adapted to receive the horizontal porof the `plate and the shoe 10 toward or away `romffoot.v Shoel'ispivotally conn tel 'With plate- 13 at 16, and, plate 13 is garnet'.

in underneath to receive extension 12, so that the surfaces o shoe 1() and plate 13 It will be understood that the slot in bai' e allows adjustment of foot 8 vbackward and forward 1n relation to-the presserfoot 3.

` are Hush at the bottom and lie flat upon base- 'The adjustment permitted by slot 14 4ro- ,When the attachment is not in use, leg withdrawn from the tenor of bar 6, and ref placed in the positionshown by dotted lines in Fig. 1, and shoe l0 is' swung around out of the way in a horizontal plane as shown-by dotted lines in Fig. 1. When the attachment .fis in this condition the sewing machine may f be used for making the preliminary seams.

The'operation of my attachment will now be readily understood.' The bar 6 may he left upon the head of the sewing machine.I since it is not in the way for anyordinary operations. When the welt quired, shoe 10 is screwed down to bed-plate 2 and may be quickly adjusted by slot 14: for

guide is regrvides 1for making welts of different wi the" the width of the welt lto be" formed. .The

seam, having been previously formed on'the fabric, asshown at 18, is slipped into slot 1 1, the upper layer of the fabric is folded over -on the top of shoe 10, foot 8 is then slipped in between the layers of the fabric, againstv the seam 18, the mortise of leg 9 slipped on the tenon of bar 6, and the device is ready to operate. 'lfhe stitch 20 is made by the' sewing machine through the three layers of the fabric 17 ,l just as is done with hemmers 4and other ordinary attachments. When another seam is to be made, foot 8 and shoe 10 areswung outof the way as previously described, t-he seam may be made on thesewing machine in the usual way, and the welt nay be quickly formed by swinging back shoe 10 and foot 8 into position.

It will be understood that very little time' and labor lis necessary to put my attachment into and out of commission, and therefore it lis not necessary to make different. operations of the seams and the Wclts, where a great y deal lof this Work is done, ,but the seams and..

the operatori'once'. x

Havingl thus /described my intention I claiml; An chinos, comprising an attachment-bar adjustably attached to the head of a sewing machine, a guide-foot adjustably appliedto said attachment-bar, an adjustable guide-t shoe'ap`p1ied over said gnide-foot, an attachment-plate for said guide-shoe' adjustably attached to the hed-plate of `a sewing,` machine j i and pivotally connected with sald guideshoe.
