GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 529,417, dated November 20, 1894; Application filed March 16,1894. Serial No. 503,910. (No model.)

To all whom it may concern:

Be it known that I, PAUL SGHOEN, a citizen of the United States, residing at Glens Falls, in the county of Varren and State of New York, have invented certain new and useful Improvements in Guides for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

In joining the edges of two pieces of fabric, (as in sewing up the sides of a shirt) by alapseam known as a flat fell secured by two rows of stitches, it has heretofore been customary to use a presser-foot scroll hemmer of i5 ordinary construction made large enough to take in the two pieces of folded fabric. The scroll hem mer has been employed for this purpose instead of an ordinary lap-seam guide for the reason that when the part of the seam where a gusset was to be inserted was reached the lap-seam guide would be in the way, while the work about the gusset can be properly manipulated with the heinmer; but in the use of the scroll hemmer in making this lapseam there has been more or less difficulty in properly guiding the edges of the two pieces of fabric so that there would be just the right amount of fullness to make the edges lap properly, the edges having a tendency to run out laterally so that sometimes, unless great care was exercised by the operator, imperfect seams would be formed.

My invention has for its object to obviate the difficulty referred to by providing a guide, 5 of novel construction, by the use of which, in connection with a presser-foot scroll hemmer, perfect lap-seams can be readily and easily made, even when the sewing machine is run at a high rate of speed, without requiring special skill or care on the part of the operator. To this end I have constructed a guide comprising a vertical flange or rib the forward or inner part of which is turned over in the form of a scroll, said rib or flange being ar- 4 5 ranged in line about midway between the two needles of the machine and-in front of the presser-foot scroll hemmer.

In the accompanying drawings Figure 1 is a perspective view of a portion of a Singer two-needle machine with my invention applied thereto, and Fig. 2is a detail front end view of a part thereof. Figs. 3 and 4 are detail plan and side views, respectively, of the guide and the throat plate, and Fig. 5 is a cross section on line 55, Fig. 3. Fig. 6 is a diagram illustrative of the work to be performed by the use of my invention.

A denotes the head at the forward end of the bracket arm of the sewing machine.

B is the needle-bar carrying two needles b, b, and O is the presser bar to the lower end of which is attached the scroll-hemmer presserfoot 0, which is, or may be, of the well known construction heretofore in use, the said presser foot being, for clearness of illustration, shown slightly lifted from working position.

D is the work-plate of the machine supported by an arm or cylinder E in which are the shuttles, the shuttle drivers and the feeding mechanism.

Attached to the throat-plate D is my improved guide consisting of the basef from which rises the vertical rib or flangeg the forward orinner part of which is turned over in the form of a scroll h which slopes downward forwardly, the said vertical flange or rib g being in a line about midway between the two needles of the machine and about central in front of the scroll heininer. (See Fig. 2.) Forward of the scroll h on the basef and extending beneath the presser-foot scroll hernmer, to assist in guiding the work to the latter, is a small rib i which slopes downward forwardly.

In the use of my invention the two pieces of fabric m, 'y, (Fig. 6) are entered into the scroll hemmer in the usual manner, the piece a: being so arranged that its edge extends up beneath the scroll h of the guide. The piece y is so held that it overlies the said scroll which thus divides or separates the two pieces of fabric so that they can be easily adjusted with relation to each other. No special care need be taken in adjusting the edge of the 5 piece y excepting to draw it well over to the right, as any extra fullness of edge thereof will be properly taken care of by the scroll heniiner of the presser-foot c. As the machine is started the operator, by the pressure IOO of afinger against the flange g, holds the edge of the piece w against said flange and at the same time easily guides the edge of the piece y over the scroll it so that the goods are thus accurately directed to the presser-foot scroll hemmer and to the needles to form lines of stitches denoted by the dotted lines 2 through the lapped edges of the fabrics. Thus, without requiring special skill on the part of the operator, and with the exercise of no great care, lap-seams may, by the use of my invention, be readily formed.

Having thus described my invention, I

: claim and desire to secure by Letters Patent- 1. The combination with a two-needle sewing machine provided with a presser-foot scroll hemmer, of a guide, for use in making lap seams, said guide comprising a vertical rib or flange having its forward or inner part turned over into a downwardly and forwardly sloping scroll, and the said vertical rib or 20 flange being arranged in a line about midway between the two needles of the machine.

2. The combination with a two-needle sewing machine provided with a presser-foot scroll hemmer, of a guide consisting of the 25 base f having the Vertical flange 9 turned over to form the forwardly and downwardly sloping scroll it, said base having also the rib t in front of said scroll and extending beneath said scroll hem mer, said flange being placed 50 in a line about midway between the two needles of the machine.

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

PAUL SGHOEN. Witnesses:
