US 8.294 Isaac Merritt Singer
Shuttle-carrier, thread controller, feed-cloth
My present invention is of improvements on a machine heretofore invented by me and for which an application is now pending.
The first part of my present invention relates to the method of carrying the shuttle;
The second part of my present invention relates to the method of drawing the stitch by the shuttle;
The third part of my invention relates to the method of controlling the thread during the downward motion of the needle by means of a friction-pad, which makes a slight pressure on the thread as the needle descends.
The fourth part of my present invention consists in placing the friction-bobbin, from which the thread is drawn by the needle, or an adjustable arm attached to the frame, so that its angle, relatively to the guide on the needle-carrier through which the thread passes, can be changed at will, so that by changing the position of the arm the motion of the needle-carrier will draw out more or less thread, as may be required.
And the last part of my invention relates to the method of feeding the cloth during the operation of sewing to determine the length of the stitches.

US 34.906 Isaac Merritt Singer
Sewing Machine
What I claim as my invention and desire to secure by Letters. Patent, is:
1. The combination of the feed-bar of a sewing machine with a cam (for causing the feeding-surface to reciprocate in one direction) and with inclined blocks, (that will cause it to reciprocate in a direction crosswise to the first,) the combination being such that the feeding surface can be caused to move either longitudinally or transversely to the support of the material, according to the guide which is employed to regulate the direction of the feed.
2. The combination of the feed-bar of a sewing machine with mechanism for raising it and lowering it, that is constructed in parts which are adjustable, so as to vary the distance to which the feeding-surface is protruded above the support of the work.
3. The combination of the same feed-bar with mechanism for moving it either longitudinally or transversely to the support of the material and also with adjustable mechanism for varying the protrusion of its feeding-surface.

US 40.209 James Bolton
Presser foot of Sewing Machine
I claim:
1. The combination of the legs of the frame of a presser-foot (which are grooved to hold a removable foot-plate) with the stem thereof by means of upright connections, so that the junction of the two sides of the frame is above the level of the foot-plate, substantially as set forth.
2. The combination of the first part of my invention with an adjusting-screw, substantially grooved frame; but as set forth.

Button Hole Sewing Machine
My invention relates to improved mechanism for forming the stitch in button-hole sewing machines and it consists in an improved construction of the stitch-forming mechanism, as hereinafter more fully described and specified...
... My improvements are designed to be at tached to the well-known "Singer" button hole sewing machine, in place of the stitch forming mechanism ordinarily used thereon.
