SPECIFICATION forming part of Letters Patent No. 379,497, dated March 13. 1888.

7 Application filed September 1, 1887. Serial No. 248,435. (No model.)

To aZZ whom it may concern:

Be it known that we, ROBERT W. THoMsoN 10 This invention relates to the method of finishing and overseaming the bar-cord and thrum ends of button holes. The nature thereof will be fully described hereinafter,and

then specifically claimed. In the drawings, Figures 1, 2, 3, 4, 5, and 6 represent the successive steps followed in finishing button-holes by this method. Fig. 7 represents a button-hole piece when finished by this process.

It will be understood that in making button-holes by the ordinary button-hole-working machine the bar-cord is continued from one button-hole to the next succeeding one,and so on throughout the entire series, and that portion of the bar-cord which extends from one hole to the other is unattached and hangs more or less in the manner of a loop also, the thread employed for overseaming the barcord around the edges of the button-hole is out after the completion of each particular button-hole, and the ends of this thread are left hanging from the small end of the buttonhole, and it is the purpose of this invention to provide a method of gathering into line and overseaming these thread ends and bar-cord without penetrating to the face side of the but ton-hole piece.

To this end, in carrying the invention into effect upon a sewing -machine, we pass the needle provided with a single thread through the material on one side of the bar-cord and thrum ends and bring it out of the material on the opposite side of said bar cord and thrum ends. There we engage the needle- 5 thread with the shuttle-thread of the machine and draw the needle back to its original position. The two threads are interlocked and drawn into the material directly under the bar-cord and thrum ends, as'represented in the drawings. Next we pass the needle over the bar-cord and thrum ends and re-engage the needle thread with the shuttlethread and again draw the needle back to position. The material is then fed one step forward and the operation of the needle and engagement of said thread is repeated, and this operation is continued and the bar-cord and thrum ends are overlaid and tied down to the material by the threads crossing and recrossing over the same. We have devised a mechanism par ticularly adapted for finishing button-holes by this method, and have described the same in an application for Letters Patent of the United States therefor, filed August 27, 1887, No. 247,556, and to that application reference may be had for a description of the mechanism we prefer to employ in carrying out the work of finishing button-holes by the method herein described. It will be observed that the needle does not penetrate through to the face side of the buttonhole piece, and no stitching is apparent on that side of the ma terial.

We claim as our invention 1. The method of finishing and staying the bar cord and thrum ends of button -holes, which consists in passing a thread into the material on one side of the bar-cord and thrumlines and bringing it out of the material on the opposite side of the bar-cord and thrum line without penetrating through to the face side of the material, there engaging it with a second thread and drawing it back through the material, then passing it over the barcord and thrum-lines and again engaging it 85 with the second thread and drawing it back to the first position, and then moving the material forward and repeating the operation of engaging the two threads above and below the bareord and thrum-lines at each forward movement of the material until the whole of said bar-cord and thrum-lines is overlaid and tied down, substantially as described.
