.MARGARET -ANNA ELIZABETH LUHRS. or HOBOKEN, NEW JERSEY. FOLDING \ATTACHMENT FOR SEWING-NIAHINES.

Be it known that I, MARGARET ANNA ELIZA- BETH LUHRS, a citizen of the United States,

and a resident of Hoboken, in the county.

of Hudson and State of New Jersey, have invented certain new and useful Improvements in Folding'Attachments for Sewing- Machines for Making Bias Folds forA plicationto Ladies Dresses, of which the ollowing is aspecification.

My invention'relates to a sewing-machine attachment for the making of bias folds, rumples, ruches, and corded or uncorded ruflles.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my folder attached to a sewing-machine. Fig. 2 is a plan view of my improvement. Fig. 3 is a cross-section of a part thereof on line 3 of Fig. 2.- The art marked 1 on the drawings represents the bed-plate of the sewing-machine.

The part marked A is the folder, consisting.

of a strip of sheet metal or other material of the'proper size bent to form a flattened oval orifice a with overlapping edges a and a leaving the longitudinal slot 0;.

tened orifice is of a width corresponding with the width of the material after it is folded. l B is the connecting-plate to which the folder is attached, and this,connecting-plate- I is secured to the bed of the machine by a thumb-screw C, passing through the slide D of the connecting-plate into an opening (not shown) in the bed of the machine- The slide D is rovided with an elongated opening d, whic enables the folder to be adjusted transverse of the machine. The connectingplate B is cut away at b 12 5 leaving thelongitudinal strips b b, to which the slide D is attached by the overturned ends d d andwhich permits the connecting-plate B and of course the folder carried thereby to be adjusted transverse of the machine.

E is the head of the machine and carries the usual presser-foot F, needle-bar G, and needle 9.

When the attachment is securedto the machine, it may be adjusted by loosening the thumb-screw Q, when it can be moved transversely of the machine, and the plate B may Specification of Letters Patent; Application filed A ril 2 1905. Serial lie-257,987.

be moved longitudinally of the machine bymoving it in either direction when the strips b and b are free to move through the overturned ends d (Z of the slide D. When the attachment is properly adjusted, it is clamped in position by the screw 0; The material is placed in the folder by turning over the edge of the cloth and folding the cloth and passing -Without any marking or any special skill.

What I claim, and desire to secure by Letters Patent, is

1. A folding attachment for sewing-machines, consisting of a plate folded toform an open-edge flattened tube, one of the edges of said plate being straight and the other edge overlapping the straight edge leaving a slot between the two edges through which the material to be operatedon may be inserted, a plate extending from said tube, said plate be-v ing provided with strips, a slide connected to said strips and adapted to move longitudinally thereon, said slide havingan opening therein in a direction transverse to the strips, and adapted to receive a screw by which the attachment may be secured to the bed of a machine.

2. A folding attachment for sewing-ma chines consisting of a flattened tube one edge of which overlaps the other but with a longitudinal opening between through which the material is to be inserted, a plate secured to the tube, said plate having parallel 'strips, a
