US 7.945 John Pepper
Knitting Machine
Having thus described the construction and operation of my improved machine, I claim as my invention the following new improvements:
My first improvement consists in the manner of producing the upward and downward motion, as above described, of the lead sinkers and the jack sinkers, so far as they move simultaneously and I claim the half jack U, vibrating on the comb-bar P and connected with the sinker frame and with the movable cross bar 28 and springs 29, for the purpose of depressing the tail-ends of the jacks and thereby raising their forward ends with the jacks' sinkers, as aforesaid. 1 also claim the movable cross bar 28, containing the springs 29, connected as aforesaid and for the purposes aforesaid.
My second improvement consists in the manner of producing the backward and forward motion of the jack and lead sinkers, as above described and
I claim the cams 7, in combination with the cross-bar 60, with the projections thereon; the hanging bars S, vibrating on pivots; the comb bar P and the half jacks U, connected with the sinker frame, as aforesaid and for the purposes aforesaid.
My third improvement consists in the manner of moving the carrier-needle and slur knob, as aforesaid and
I claim the combination of the cam V and the shoe and shoe-plate, for the purposes aforesaid.
I also claim the combination of the cam V, with the shoe 5; the movable shoe plate f; the chains h and l; the semi-circles and hubs, or wheel and hub; the bar W, connected with the slur carriage and the slur-knob Q and the horizontal bar X; the carriage q, connected with the carrier-needle, q2 for the purposes aforesaid.
My fourth improvement consists in the manner of moving the ribbed work attachment and producing the ribbed stitch, simultaneously with the plain stitch, without the machine slide and with one presser, as above described and
I claim the combination of the cams 9, with the levers 18, connected with the frame 17 and with the ribbed needle bar 16, for the purposes aforesaid; also, the same in combination with the presser r, connected, moved and operating as aforesaid and for the purposes aforesaid.

US 8.163 Rufus Ellis
Knitting Machine
What I claim as my improvement is the arrangement of the needles in the plane of the endless belt, instead of at right angles to it, in combination with the arrangement of the driving pinion 6
and the projecting joints x, x, x &c, of the links of the belt, on the outside of the belt; the belt being supported and the whole being applied to the stitch hook, yarn guide and presser and
made to operate together and with the work hanging on the inside of the belt, substantially as hereinbefore specified.

US 8.172 John Pepper
Knitting Machine
What I claim as my invention and desire to secure by letters patent:
First. Is a sinker, to be used in machines for knitting, so constructed as to form the loops upon the needles used in knitting two separate fabrics at the same time and at one operation and of sufficient weight to draw the requisite quantity of yarn from the supply to form the loops required.
Second. Is a slur, to be used in knitting machines, so constructed as to let each sinker drop to the falling bar and draw the requisite quantity of yarn from the supply to form the loop, or loops, between the needles, before it allows the succeeding sinker to drop and act upon the yarn.
Third. Is a falling bar, so constructed that the slurs and slur boxes, traverse upon it, instead of traversing a separate bar.
Fourth. Is the combination of the sinkers, stop bars, combs and needles that traverse, so arranged as to knit two separate fabrics at the same time with one and the same set of sinkers and slur.
Fifth. I do not intend to limit myself to the precise construction described in the foregoing specifications, but to use such forms of construction as will answer the purpose intended.

US 8.262 J. H. Barsantee
Knitting Machine
Having thus described my improvements, what I claim as new therein and desire to secure by letters patent, is:
First. The sliding, independent yarn carriers, each governing an independent thread for each needle, substantially in the manner and for the purpose as described.
Second. I claim operating the yarn carriers simultaneously by means of the conical ring (U') working in the inclined slit in the carriers, substantially as set forth.

US 8.282 W. H. Akins & J. D. Felthousen
Sewing Machine
... what we claim therein as sew and desire to secure by letters patent, is: First. The combination and arrangement of the pitman, driving-bar, shuttle and adjustable set screw, for the purpose of allowing the pitman a continuous motion, whilst the shuttle-bar and shuttle is momentarily stopped, to allow the needle to draw up the stitch, as herein described and represented . Second. We claim bringing up the needle with a sudden jerk, after the stitch is formed, for the purpose of tightening up the stitch, after the manner of hand-sewing and adjusting the same to any thickness of material to be sewn.

US 8.294 Isaac Merritt Singer
Shuttle-carrier, thread controller, feed-wheel
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.

Sewing Machine
What I claim as my invention and desire to secure by letters patent, is: First. The combination of the rotating hook, to extend the loop on one thread, with a reciprocating bobbin, to carry the other thread through the loop so extended, for the purpose of interlacing the two threads together, whether the parts be severally arranged and operated as herein set forth, or in any other way substantially the same. Second. The hollow mandrel, constructed substantially as herein set forth, with a groove on its periphery, to give a reciprocating motion to the bobbin, a segmental screw thread, to feed the cloth forward as the sewing progresses and a hook and groove on its extremity, to form loops on the needle thread, in combination with a reciprocating bobbin; the whole arranged and operating substantially as herein set forth.

US RE188 Sherburne C. Blodget & John A. Lerow
Sewing Machine
Improvements in Sewing Machines. Having thus fully described our improved sewing machine, we shall state our claim as follows:
What we claim as our invention and desire to have secured to us by letters patent in the above-described rotary sewing machine, is arranging the shuttle which carries the filling thread so that it shall revolve horizontally in a circular shuttle-race, said shuttle being constructed with a curved front and pointed nose, which shall travel in a circular guiding groove sunk below the bottom of said race, so that the shuttle shall inwardly pass through the loop formed in the needle thread; all as hereinabove set forth.
We also claim the pad or washer under the spring arms which carry the shuttle for keeping the filling thread straight, as hereinbefore explained. Furthermore, we claim the combination of the wide spring c1, c1 and the bent lever-spring f1, f1, operating as hereinabove described, or any contrivance substantially equivalent thereto, for relaxing the needle thread when the loop is to be formed and holding it rigidly when each stitch is to be tightened, as hereinabove set forth.
We also claim the converging nipper springs through which the needle, &c, passes to keep the thread up and prevent the needle from splitting or breaking it, as hereinabove set forth.
We also claim the combination and arrangement of the spring arms q1, q1, q1, q1, with the cam ledge, s1, s1 or any other means essentially the same, for the purpose of disconnecting, alternately, said arms from the shuttle, for the purpose of allowing the shuttle to pass through the loop, as herein described and represented.
