FRANK JOSEF KAUFMANN, OF FULTONVILLE, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE SINGER MANUFACTURING COMPANY, A CORPORATION OF NEW JERSEY.

Patented March 10, 1908.

Application filed February 4, 1905, Serial No. 244,164. Renewed. January 11, 1907. Serial No. 351,903.

T all whom it may concern:

Be it known that I, FRANK JosEFKAUF- MANN, a citizen of the United States, and a resident of Fultonville, in the county of Montgomery and State of New York, have I invented a new and Improved Sewing-Machine Attachment, of which the following is a full, clear, and exact description.

The invention relates to an attachment for sewing machines, intended especially to facilitate sewing fourchettes on to gloves, and

for uniting other sections of fabric or othertheir proper juxtaposition during the sewing operation. 1

Hereinafter reference is to be had to the accompanying drawings which illustrate as anexample the preferred embodiment of my invention, in which drawings like characters of reference indicate like parts in the several views, and in which Figure 1 is a perspective view showing my invention in operation; Fig. 2 is a section taken essential y on the line 2-2 of Fig. 1; Fig. 3 is a section taken essentially-on the line 3-3 of Fig. 1; and Fig. 4 is a section taken essentially on the line 4-4 of Fig. 1.

The work plate 10 of the machine is formed with an opening 10 leading from the front edge of the work plate toward the feed dog and needle, and terminating as shown best in Fig. 4 in an upwardly inclined inner part or throat 1O leading gradually to the needle. In this opening 10 is adapted to lie a gage plate 11 which terminates, as shown best in Fig. 4,.in a tapered part overhanging the extremity 10 of the opening so as to leave a passage from beneath the gage plate, as the drawing shows. The gage late 11 is formed on its upper side slightly rig tward of the stitch line, with ashoulder 11", adapted to have the edge of one of the sections of material run against it, and serving to guide said section of material in its movement tothe needle. 10 indicates a continuation of the shoulder ]1 which is formed by a block fastened securely to the work plate 10. The gage plate 11 has a shank 11 which lies on top 0 the work plate 10, and is connected pins with a nut 21 engaged by a screw 22 hel thereto by a hinge 12, which permits the gage plate to be raised as indicated by the broken ines in Fig. 3. The pintle of said hinge 12 moves with the gage plate and carries a block 14 having angularly disposed flat faces 14 which coact with a spring 15 fastened to the work plate, and which serve to hold the gage plate yieldingly either in the active position shown in full lines in Fig. 2, or in the raised or inactive position in which the gage plate lies approximately perpendicular to the work plate. A tension member 16 is carried by the gage plate 11, through the medium of 17 which project loosely through the gage plate and have heads at their u per ends fitted in cavities in the gage p ate. This gage member or shoe 16 lies under the gage plate and is adapted to bear on the other section of fabric which passes under said plate, as will be fully set forth hereinafter. 16 indicates a spring for pressing the tension member into action.

On its under side the work plate is formed with two guides 18, .which extend transversely of the line of movement of the goods, and carry a slide 19 which has a reduced inner portion 19 adapted to extend under the opening 10 in the work plate, form a support for the second section of the material as it passes under the gage plate 11. 20 indicates a rib or bead which is formed or secured under the work plate adjacent to the hinge 12, and which is engaged on its under side by said reduced extension 19 of the slide 19. The slide 19 is also formed with a shoulder 19 which serves as a gage, and which upon the adjustment of the slide is moved toward or from the said rib or bead 20, thus increasing or diminishing the width of the passage under the gage plate 11. The slide 19 is further provided with a cavity 19 opposite the tension shoe 16 and adapted to receive the adjacent end of said shoe when the slide is moved to its extreme inward position. As the tension shoe 16 extends crosswise of the direction of feed and parallel with the direction of adjustment of the slide 19, it will be observed that the cavity 19 form's practically a notch in the shoulder 19 only slightly wider than the comparatively narrow shoe 16, the shoulder 19 being continuous excepting where cut away to provide such cavity. Said slide is fitted with any desired means for adjusting it, for examcp le, to

and to iio turn in a lug 23 depending from the work plate. By the operation of this screw 22 the slide may be moved in or out, and the width of the passage for the bottom section of material increased or diminished at w ill.

When using the machine for sewing fourchettes on to gloves, the material forming the glove proper is laid on the work plate and the fourchette is passed through the opening 10 and laid on the extension 19 of the slide 19, and the gage plate '11 is then thrown down so as to lie over the fourchette and under the glove proper. The edge of the glove to which the fourchette is to be joined is then run along the gage shoulder 11, and the slide 19 is properly adjusted to hold the corresponding edge of the fourchette engaged with the wall or bead 20. The fourchette passes under the tension shoe and thence up through the extension or throat 10 of the opening 10 under the glove, so that thetwo may be stitched together, as is indicated in Fig. 4.

In Figs. 1, 3 and 4 of the drawings a indicates the glove proper and b indicates the fourchette. The tension device or shoe 16 may be utilized to regulate the movement of the fourchette toward the stitch forming devices.

It is apparent that various other operations may be performed with the aid of my invention and that it is in no way limited to the specific use above described.

From the foregoing description, it will be seen that the under section or strip of material b passes to the needle through a channel or ideway below the upper face of the work-p ate having upon oneside the adjustable edge-guiding shoulder 19 and upon the opposite side the guiding edge of the rib or bead 20 with the slide-plate 19 forming its bottom, while -the gage-plate 11 disposed within the opening 10 forms a cover plate for such channel and also constitutes a movable section of the work-plate afiording a support for the upper section a of the material to which the strip 1) is to be united. It is evident that the essential part of the opening 10 is its forward or throat portion 10 through which the strip 1) is delivered to the stitch-forming mechanism, and that its extension to or toward the front edge of the work-plate, as illustrated in the accompanying drawings, is not material to the present invention, excepting in connection with the gage-plate forming the removable section 11 of the work-plate recited as a feature in certain of the appended claims. Various changes in the form, proportions and minor details of my invention may be resorted to without departing from the spirit and scope thereof; hence I consider myself entitled to all such variations as may lie within the terms of my claims.
