Rotary Take Up for Sewing Machine

My invention has for its object to provide a take-up device especially adapted for use with machines running at high rates of speed and my invention consists of a take-up device in which the take-up function is performed by a rotary traveling shoulder, on which the needle thread is held by a retaining-bar until the bob bin-loop has been drawn up, the stitch tightened and sufficient thread drawn from the spool for a new stitch and in which, when the device is used for machines running at very high speeds, a preliminary drawing of the thread is effected, all as fully set forth hereinafter and as illustrated in the accompanying drawings.

Button-Hole Sewing Machine

The object of my invention is to provide a simple and effective mechanism for automatically barring button-holes after they have been otherwise completely finished by the stitch forming mechanism of a button-hole sewing machine. To this end I mount the guiding button for the work-clamp on a slide which is at the proper moment automatically thrown into action, so as to reciprocate the said work clamp across the line of feed and in opposition to the lateral reciprocating movement of the needle-bar of the machine and thus form a bar across the end of the otherwise finished button-hole to fully complete the same.

...I do not wish to be understood as claiming, broadly, an automatic mechanism for reciprocating the cloth-clamp of a button-hole sewing machine across the line of the feeding movement of said clamp for the purpose of barring button-holes which have been other wise completed, as I am aware that such an invention is shown by the application of Charles S. Jordan, No. 170,486, filed July 2, 1885; but in Jordan's machine the work-plate which supports the cloth-clamp and which carries the button for guiding the latter is made movable and is reciprocated to give the clamp the proper barring movements, while in my machine the work-plate is stationary, but the guiding-button is movable independently of said plate...

Button-Hole Sewing Machine

The object of my invention is to provide a simple and effective mechanism for automatically barring the ends of eyelet button-holes which have been otherwise finished by a button-hole sewing machine and for automatically stopping the machine when the barring operation is completed, or, if desired, for stop ping the machine when a button-hole is worked without barring the same. In the drawings, is a sectional elevation of a "Singer" button-hole sewing machine embodying my invention...

... the work-clamp is guided, said button being thus movable to and fro in a direction transverse to the feeding movement of the work-clamp, as described in Letters Patent US 360.433, dated April 5, 1887, application,Serial No. 195.900, filed March 20, 1886, the slotted plate R being stationary, as is usual.

Thread-Drawing Devices for Sewing Machine

My invention consists of the combination, with a sewing machine, of a device for positively seizing, gripping and feeding forward the thread and in the combination of such a device with the wax-pot and stripper and with the gripper of a wax-thread sewing machine, as fully set forth hereinafter, so as to relieve the other parts of the machine from the irregular strains resulting in drawing the thread from the wax-pot or bobbin to secure a uniform placing of the lock and a more even and regular stitch than would otherwise result. My invention further consists in the particular construction of the thread-feeding device.
