SPECIFICATION forming part of Letters Patent No. 747,047, dated December 15, 1903.

Application filed January 9, 1908. $erial No. 138,426. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN I/V. DARLEY, Jr., a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Means for Securing Buttons to Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in means for attaching buttons to leather, skins, or woven fabrics; and it consists in certain novel features that will be hereinafter described and claimed.

Reference is bad to the accompanyingdrawings, in which the same parts are indicated by the same characters throughout the several views.

Figure 1 shows four stages of sewing the button on a fabric. Fig. 2 is a plan view of a series of buttons secured to a fabric before the ends of the threads have been out. In the two foregoing figures three separate threads are used. In Fig. 3 is shown the use of two threads only, the sewing-thread being looped on the bottom of the fabric in the manner of the well-known chain-stitch.

A represents the fabric on which the button is to be sewed.

B, B, B and B represent buttons.

0 represents the sewing-thread, carried by the needle. carried by the shuttle, and E represents the winding-thread, which is applied after the button has been sewed on the fabric.

The numeral 1 in Fig.1 indicates the sewing-thread after it has been looped twice once through each hole of the button B and after the shuttle-thread has been put through each loop. The parts are shown diagrammatically with the loops spread out, so as to secure clearness in thedrawings. The numeral 2 denotes a further stage in which the sewing-thread and the shuttle-thread have been looped several times. The numeral 3 indicates a third stage, in which the sewing on of the button has been completed and the winding-thread has been applied, and mu moral at shows a further stage, in which the operation is completed, in which the ends of D represents the shuttle-thread,

the winding-thread have been knotted and all the loose ends of the three threads have been snipped off. In practice all of these operations are completed while the button is in the machine and before another button is applied.

In Fig. 2 are shown four buttons, each of which has reached the stage indicated by the numeral 3 in Fig. 1. This figure shows the winding-thread and the shuttle-thread eX- tending from button to button, which is the case when all of the given series of buttons have been applied to the fabric. The winding-thread is then out between the buttons and the ends knotted together, as before stated, while the shuttle-thread is also out between the buttons, and then the free ends of all three of the threads are cut close to the buttons, the latter then furnishing the finished appearance indicated by the numeral 4 in Fig. 1.

Itwill thus be seen that I show means for attaching buttons to fabrics by means of three separate threads-one thread (which I call the sewing-thread) passing through the button and the fabric, the other thread (which I call the shuttle-thread) engaging in the loops of the sewing-thread at the back of the fabric, and the third thread (which I call the winding-thread) winding around the neck of the button. This winding-t1] read is tightly wound on, and it is not out until the fabric is removed from the machine, at which time the free ends are tied together, so that there is no tendency to unwind.

It will be obvious that instead of having a sewing-thread and a shuttle-thread I may use a single thread in combination with the winding-thread, the sewingthread being looped on itself under the fabric, as in the case of the well-known chain-stitch machine. This is shown in Fig. 3, where the numeral 2 indicates diagrammatically the sewing-thread looped to form a chain-stitch and the numeral 3 shows the button after the sewingthread has been cut and after the ends of the winding-thread have been out, but before they have been knotted. The finished prodnot will be of the same form as indicated by the numeral 4 in Fig. 1.

By spacing the button from the fabric any desired length of neck for the button may be secured, this neck being protected and stiffened by the subsequent winding.

In the claims I use the term fabric to indicate any article or material to which a button may be applied.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. As a new article of manufacture a button spaced from said fabric, a thread passed through said button and said fabric in such a way as to form aneck of thread between said button and said fabric, means for securing the thread to said fabric, and separate winding-thread wound around said neck of thread and having its ends fastened together, substantially as described.

2. As a new article of manufacture, a cloth or like fabric, a button spaced from said fabric, and means for securing said button to said fabric by a neck of thread, said means including three independent threads, one. thread passed through the fabric and the eyes of the button, a second thread at the back of the fabric engaged with the first thread, and a third thread wound around the first-named thread between the fabric and the button and having its two ends secured
