OVEREDGE SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 736,199, dated August 11, 1903. Application filed July 25. 1902. SerialNo.116.980. (N0 model.)

To all whom it may concern.-

citizen of the United States Of America, residing in Providence, in the county of Providence and State of Rhode Island, have invented Improvements in Sewing-Machines, of which the following is a specification.

The object of my invention is to construct a sewing-machine for making automatically and with speed and economy an edging On lace, haircloth, or other open-work goods,

7 Be it known that I, STOCKTON BORTON, a

- such as to wholly prevent the appearance of whiskers on the finished edge of the goods and at the same time insure the secure attachment of the edging to the goods.

, In carrying out my present invention I use overseam orother overedge stitchingandpreferably employ cords to produce an edging embodying the invention formingthe subject of my Letters Patent No. 556,300, dated March 10, 1896, and in making edgingpf the patented construction I employ the combination of mechanism forming the subject of my Letters Patent No. 561,043, dated May 26,1896. Although I prefer to employ cords in making edgings on the machine of my present inven- 7 tion, I do not wish to .limit myself thereto.

By the term whiskers I'intend to designate the ends of the threads of the lace, haircloth, or other open-work goods which project beyond the cut edge of the goods and which have heretofore been liable to protrude between and beyond the overseaming-stitches "1. and the cords laid thereon. According to my present invention I provide means for brush- ,ing back and laying on each other (and, if desired, bending or folding under or over the edge of the goods) these out ends of the threads or whiskers as the goods are fed through the machine. This brushing device may be a simple edge-guide which is placed-between the needle and the trimmer, as I will describe.

In the accompanying drawings, Figure 1 is aplanview of one form of overseam sewing;

machine in which my invention may be employed. Figs. 2, 3, and 4 are detached views in plan, edge, and inverted plan of a form of presscr-foot which may be employed in carrying out my invention.

, Fig. 5 is a sectional view of a part of the machine, drawn to an enlarged scale, on the line 5 5, Fig. 6. Fig. 6' is a view looking in the direction of the arrow, Fig. 5. Fig. 7 is a view, on a still larger scale, of parts to illustrate my invention; and Fig. 8 is a view of a piece of hail-cloth or like open fabric in process of being edged.

I do not wish to restrict myself to the use of any particular construction of overedge sewing and trimming mechanism for the purpose of carrying out my invention; but I prefer to employ the overseaming and trimming machine for which patents were granted to myself and'Oharles II. Willcox April 5, 1892, Nos. 472,094 and 472,095. So much of the machine of said patents as is necessary to an understanding of mypresent invention is illustrated in the drawings. Thus A represents the bed-plate, e the needle-bar carrying the needle 10, and h is the looper. The presserfoot q is carried by a resser-bar 35, which is attached to or inone piece with a sleeve 36, secured to the shaft 'r, Fig. l.- Parallel with this shaft 1' is a shaft 8, carrying the vibrating arm 41, in the outer end of which is mounted the upper shear-blade 42 of the trimming device, the lower blade 90 being adj ustably fixed in the frame, Figs. 5 and 6.

The presser-foot q has in addition to the usual chaining-finger q a downwardly-projecting piece G underneath. A somewhat similar piece was employed in themachine of my Patent No. 561,043 as an eye for the lower cord to be fed to the underside of the edging, and I may employ this piece in part for a similar purpose here if I use such under cord in the edging; but I provide this piece G in the present instance for another purpose-namely, to serve as an edge-guide to bend or brush back the projecting ends of the whiskers or ends of the threads cut by the trimming device and before the goods reach the overedging devices in being fed through the machine. The cord-guiding notch in the piece G is best illustrated in the side view of the Presser-foot, Fig. 3, but the edge-guiding part of the piece G is best illustrated in the enlarged view, Fig. 7.' The goods being fed. by the feed-dog m, Figs. 1 and 5, through the machine in the direction of the arrows Fi s.

7 and 8, the edge will first .be trimmed by the shearing action of theblades 42 and 90, Fig.

' 7, and then the pr'ojecting cut ends or whiskers will be brushed back onto each other in the direction of the line of feed, and while in this condition the overedge-stitchforming devices will apply the overedgestitches around these brushed-back whiskers,

no and so not only prevent their protruding through and between the overedge-stitches, but also more securely hold the overedgestitchingin place on the edge of the goods whether cords such as was be used or not.

:5 It will be seen that the important feature is thatnot only shall the edgeguide G be located between the trimmer and the stitchforming mechanism in the direction of the feed, Fig. 6, but that the edge-guide G shall lie between the trimming-line and the sewingline, Figs, 5, v7, and 8.. In order to insure that this edge-guide'G shall always lie ina certain relation to the needle 10 and between the latter and the trimmer in the direction at -right angles to the feed, vI make the presserarm 36, which carries this guide, non-adjustable by aflixing to the shaft 7', Fig. 1,.a collar 0, which bears against the housing 37 and'keeps the-shaft r and the parts carried by it always as far to the left aspossible. By this means the adjusting thumb-screw 40 has its flange 420 bearing only against the trimmer only.

end of the shaft 5 to laterally. adjust the goods, whereby the overseamingmay be formed over and inclose these bent ends, substantially asdescribed.

2. The combination of overedge sewing mechanism and trimmer mechanism with .50 means between the trimmer and needle for bending back. inthe direction of the line of feed the cut ends of the threads of open-work goods, and means for laying a cord over said cut'and bent ends, whereby the overseaming maybe formedover and inclose the cord and bent ends, substantially as described.

' .In testimony whereof I have signed my name'to this specification in the presence of two subscribing witnesses.

STOCKTON BORTON.
