To (LZZ whom it may; con/007w..-

Be it known that I, PAUL SCHOEN, a citizen of the United States, residing at Glens Falls, in the county of Varren and State of NewYo1'k,l1ave invented certain new and useful Improvements in Bin din gAttachments for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide a binding attachment for sewing-machines of such construction that two pieces of work, one or both of which may have considerable fullness, may be joined together and a bind ing be sewed on to cover the raw edges thereof all at one operation,thus adapting a sewingmachine for use in sewing very full sleeves of ladies dresses, shirt-waists, -&c., to the waist proper, and simultaneously to apply a binding which will cover the raw edges, this work all being done by means of my invention at a single operation instead of requiring several operations, as heretofore.

In carrying my invention into effect I employ a binding-holder or binder of the usual construction and arrange the same on the work-plate of the machine at an obtuse angle or at nearly a right angle to the line of the feed, and I apply to the work or throat plate of the machine, closely adjacent to the needle, a binding-guid e having a simple concaved guiding-face, this binding-guide being comparativelyshort and having its concaved face in line with the feed of the work, or nearly so, said binding-guide being recessed into the throat-plate, so that the upper face of the lower limb of said guide is flush with the upper surface of the throat-plate, or approximately so. Between the binding-holder and binding-guide I preferably employ what I term a binding-guard, which assists in directing the binding from said holder to said guide. In connection with this binding-guide I employ a presser-foot, which is cut away or recessed on one side, so as not to interfere with the short bindingguide which is arranged mainly within the line of the presserfoot, said foot, however, having an extended upwardly-inclined toe which projects out in front of the binding-guide toward the operator, so as to permit of the passage beneath the said foot andinto the binding-guide of almost any amount of fullness of goods incidental to gathers, rnffles, &c. The feed-dog, which is employed in connection with this extended presser-foot and binding-guide, is a double one, having two serrated portions, one on each s'ide'of the needle of the machine, said feed-dog being partly rearward of the needle and being also extended out in front toward the operator as far as or farther than the extended toe of the presser-fooinso as to assist in forcing those portions of the Work having great fullness beneath the presserfoot.

In the accompanying drawings, Figure 1 is a perspective view of a portion of the workplate of a sewing-machine having my invention applied thereto. Fig. 2 is a plan View of the same with the presser-foot omitted. Fig. 3 is a front View, and Fig. 4 a side View, illustrative of my invention. Fig. 5 is a section on line 5 5 of Fig.2, and Fig. 6 shows the binding-guard and gage or edge-guide in perspective.

A denotes a scroll-shaped binding-holder of ordinary construction and which is of U- shaped tubular form at its delivery end, said binding-holder being provided with a shank a, by means of which it may be adjustably attached to the work-plate of the machine. This binding-holder is preferably arranged at an obtuse angle, or nearly at aright angle, to the line of movement of the work.

B denotes an open binding-guide arranged closely adjacent to the needle of the machine, and consisting simply of a slightly-flaring U shaped piece of metal, the lower limb of which is recessedinto the throat-plate b, so that the uppersurfaee of said lower limb is about flush with the upper surface of said throat-plate. The open binding-guide Bis so arranged that its U -shaped guiding-surface extends approximately in the line of the feed of the work.

C denotes the presser-foot, having a recess a, which receives the binding-guide B, the toe of the said presser-foot being upwardly inclined and extended forward toward the operator in front of the said binding-guide, so that any desired fullness of work can be fed in beneath the said presser-foot with its edge received by the binding-guide B and the doubled binding which passes through said guide and which is to be sewed onto the raw edges of the material simultaneously. with the operation of joining two parts of a garment together.

D denotes the feed-dog, which is a double one, the two portions of said dog being on opposite sides of the needle, said feed-dog extending not only rearwardly of the needle, but also well forward, so that its front end toward the operator is as far forward as the upwardly-inclined extended toe of the presserfoot.

Interposed between the binding-holder A and the binding-guide B, I preferably employ an open binding-guard E, which is carried by a shank e, attached to the throat-plate of the machine in such a manner that the lower edge of the said guard will be lifted slightly above the said throat-plate. I also preferably employ a gage or edge-guide f, consisting of an upturned lip or ledge forming part of a plate F, attached to the throat-plate of the machine beneath the shank e, carrying the binding-guard E.

In the operation of my invention the binding strip or tape is passed through the binding-holder A, and in so doing is folded into U shape in cross-section when delivered from the U-shaped tubular end of said holder, the binding passing in this form over the binding-guard E, which assists in directing it properly to the binding-guide B, where the binding is now reversed in form, so that what was the convex side of the folded binding in passing out of the delivery end of the binding-holder-A and over the binding-guard E becomes the concave side of the folded binding as the latter is passed through the binding-guide B, so that the work passing beneath the presser-foot is inclosed by the binding which moves forward to the needle with the work, the edge of the latter opposite to and rearward of the needle being held by the operator against the gage or edge-guide f as the work is fed forward. Owing to the fact that the binding-guard is so placed that its lower edge is slightly above the throat-plate the lower edge of the binding can extend slightly beneath the same as it passes forward to the binding-guide, and owing also to the fact that the latter is recessed slightly into the throatplate, so that the upper surface of its lower limb is about flush with the throat-plate, the lower edge of the binding can be easily guided beneath the edgev of the work, so that the binding will not fail to properly inclose both edges of the latter, there being no difiiculty in directing the upper edge of the binding properly with reference to the edge of the work.

Thus with the use of the several parts constituting my invention, arranged and operating as described, twoparts of a garment, one or both of which may be very full, owing to gathers therein, may be sewed together, and simultaneously with this operation a binding to cover the raw edges of the work may be applied to the garment-sections thus joined, thereby performing at one operation the work which has heretofore required several opera; tions.

Having thus described my invention, I

claim and desire to secure by Letters Patent- 1. In a sewing-machine binding apparatus, the combination with a throat-plate having a recess, of an open binding-guide arranged adjacent to the needle and having a U-shaped guiding-surface extending approximately in the line of the feed of the work, said guide being arranged in said recess with the upper surface of its lower limb flush with the upper surface of said throat-plate, 01 approximately so, a presser-foot having also an upwardly inclined toe portion extending forward of said guide, a binding-holder arranged at an angle to the said binding-guide, and serving to fold the binding before it passes to the latter, a feed-dog extended forward of said bindingguide and binding-holder beneath said toe portion of said presser-foot, and an open binding-guard interposed between the delivery end of the said binding-holder and the said bin cling-guide and slightly elevated above the work-plate.

2. In a sewing-machine binding apparatus, the combination with a bindingguide, of a presser-foot having a notch or recess at one side in which said binding-guide is arranged and having also an upwardlyrinclined toe portion extending forward of and directly in front of said guide, of a double feed-dog having two parts both of which extend forward of said binding-guide beneath the said toe portion of said presser-foot andon opposite sides of the line of the needle; whereby, owing to the combined operation of the said binding-guide and extended presser-foot and double feed-dog, two parts of a garment, one or both of which may be very full, and a bind} ing to cover the raw edges of the work, may all be simultaneously presented to the needle, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
