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 8.282                   W. H. Akins  &  J. D. Felthousen 

Lock-stitch machine

Improvements in Sewing Machines. Having thus fully described our invention, 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.

Lock-stitch, feed-wheel, thread controller

Improvement in Sewing Machines. What I claim as my invention and desire to secure by letters patent, is giving to the shuttle an additional forward motion after it has been stopped, to close the loop, as described, for the purpose of drawing the stitch tight, when such additional motion is given at and in combination with the feed motion of the cloth in the reverse direction and the final upward motion of the needle, as described, so that the two threads shall be drawn tight at the same time, as described. I also claim controlling the thread during the downward motion of the needle by the combination of a friction pad, to prevent the slack above the cloth, with the eye on the needle carrier, for drawing back the thread, for the purposes and in the manner substantially as described. I also claim placing the bobbin from which the needle is supplied with thread on an adjustable arm attached to the frame, substantially as described, when this is combined with the carrying of the said thread through an eye or guide attached to and moving with, the needle carrier, as described, whereby any desired length of thread can be given for the formation of the loop without varying the range of motion of the needle, as described.

Lock-stitch, rotary hook, for carrying upper thread around bobbin containing under thread

Improvements in Sewing Machines. 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

Improvements in Sewing Machines

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.
