Sewing Machines. The conception and improvements in these machines belong exclusively to this country and we are indebted solely to American ingenuity for their present perfection.

"Seven patents" have been granted for improvements in these machines. One was for the introduction of a stop motion, which, when the thread gives out or breaks, stops the feed. Two others were improvements in the feed motion. In one of these, the position of the lower needle is regulated by the thickness of the cloth, so that they will with certainty pass through the loops alternately formed on each side of the cloth. In another of these machines, the feed motion is controlled by the length of the stitch. The bars carrying the needles are held against one side of the guides through which they pass by a spring. This guide is sufficiently wide to allow the bar to vibrate the width of the longest stitch required. The turning of this guide varies the length of the stitch. The cloth is drawn forward by a weight; as one needle is withdrawn, the weight carries the needle (with its bar) that is left in the cloth forward, until the bar is arrested by the guide; this gives the length of stitch to the opposite needle. In another, a revolving hook, in the cavity of which is placed the shuttle, supplies the place of the second needle or the vibratory shuttle.

"Four patents" were granted for improvements in knitting machines. One of these was for a stop motion, similar to that used in spinning frames. In another, a rotary machine, a patent was granted for giving the cloth-beam a rotary motion, the same as the needles, in order to avoid twisting the fabric.

Looms. "Twenty one patents" have been granted for improvements in looms. Three of these were for improvements in the pincers and pile-wires for pile fabrics. Another was for communicating a positive motion to the shuttle boxes, pattern-wheel and jacquard apparatus, by means of a star-wheel, which not only gives motion to the parts, but holds them firmly when required. Another patent was for improvement in jacquard cards. A very ingenious loom was patented, embracing several improvements such as moving the shuttle-boxes, operating the needles by forked marches and stop motions for arresting the loom when the weft-thread breaks, or when the shuttle is in the wrong box. A vibratory roller temple was patented. This temple, when the lay beats up, recedes a distance equal to the yielding of the cloth and, on the backward motion of the lay, follows up the reed with the cloth and holds the web near the cloth-making point. I will close this report with a notice of a foreign loom, patented. This invention consists in a peculiar and ingenious mode of raising the loops of such fabrics as Brussels carpets without the use of pile wires. The mode by which this is done is by partially beating up certain picks of the weft-threads as they are woven into the warps; that is, leaving a space between two of the picks, or shoots of weft and then throwing in a number of close shoots and, after that has been done, driving the whole of these successive shoots firmly up on the foundation warps to the previously-formed work, by which means the terry parts of the work, occupying the space between the open picks, will be puckered into loops on the surface of the fabric and form the raised portion of the warp. In effecting the above object it is necessary to loosen such portions of the warp as are necessary to form the loops and also to tighten the ground warps, whilst the lay is beating up the weft, to make fast or secure the loop. The mechanism by which this is accomplished is too complicated to explain without the aid of drawings. The importance and general usefulness of the machines embraced in this class are worthy of a more extended notice given to them; but the necessary brevity of these reports will not admit of it.

US 8.773                               William  Henson

Improvement in Knitting Looms

Having now described the construction and operation of my improved knitting loom, I disclaim the invention of warp-machines; also the invention of needles, guides, sinkers, presser and the actuating cams or cut wheels for racking the guide bar; the same having been used prior to my invention. But what I do claim and desire to secure by letters patent, is:

First. I claim the relative motions of the needles, hooks and presser, as combined to form the looped or knitted fabric, in combination with the stops or guards on the hook bar, to prevent the presser from coming in contact with the hooks; the whole being constructed and arranged substantially as herein set forth.

Second. I claim the combination of mechanism for regulating the take-up motion, according to the quantity of fabric formed, without varying the tension of the fabric, substantially as described.

US 9.139                                  Charles  Miller

Improvement in Sewing Machines

Two threads, one of which is passed through the cloth in the form of a loop and the other carried by a shuttle through the said loop, making a stitch similar to what is termed in hand sewing "the back stitch".

Having fully described my invention, what I claim as new and desire to secure by letters patent, is:

First. The stopping or prevention of the operation of the feed, substantially as herein described, when the thread breaks, or is otherwise prevented from forming a loop by attaching the stud q, or its equivalent, through which the feed lever U, is operated upon by the feeding cam to a lever V, the said lever V, being subject to be operated upon in such a manner as to withdraw the said stud or equivalent, from the operation of the cam by a sliding piece W, attached to the picker f, which drives the shuttle forward for filling the said sliding piece, requiring to be caught and moved by every loop to prevent its operation on the said lever V.

Second. Sewing or making the "back stitch" by folding or bending the cloth or material over the edge of a guide-plate 6, or any other suitable edge and passing each loop through the cloth or material on each side of the said bend and each succeeding loop through in advance of the preceding one and half way between the two preceding perforations, substantially as herein set forth.

US 9.380                             John  G.  Bradeen                                 

Short thread, running stitch

The same kinds of stitches or sewing, as that of Frederick R. Robinson, for which Patent US 7.824 was granted on December 10, 1850.

I claim as my improvement the two rotating draft-hooks, (or their equivalents,) separate from the needles, in combination with the two needles and two thread guides, made to operate together, substantially as specified. And I claim the improvement of so constructing and operating the needles and thread-guides, that each needle, directly after passing into and through the cloth, shall pass through the thread guide, which is on that side of the cloth opposite to the side of it in which the needle first enters, meaning to claim the arrangement of each needle and its thread guide respectively on opposite sides of the cloth, they being constructed and operated in the manner specified. In F. R. Robinson's machine, they are arranged and made to operate on the same side of the cloth. And I also claim the combination of the rocking thread-lifter or its equivalent, with the needle and presser; the said thread-lifter being operated, as described, by the thread-guide lever or any other proper means.

*********************************************************

US 9.435                                 Daniel  Tainter

Improvement in Rotary Knitting Machines

I do not claim the combining one or more draft rollers and a take up roller or drum in one frame, which, when put in rotation, shall carry them simultaneously around with it, so as to draw forward and wind up a rope or cord, or like manufacture, formed of strands twisted together; nor do I claim the application of a take-up roller or mechanism, as used on either a common warp or flat braid knitting machine. What I claim as my invention is to so combine a draft and take-up roller and mechanism for revolving it, with a rotary series or set of needles and other mechanism of the above mentioned peculiar kind for knitting, that such draft roller shall rotate simultaneously or with the same velocity with such series of needles, so as to prevent the longitudinal rows of stitches from being produced in helical lines and the evil consequences resulting to the fabric therefrom. I also claim the arrangement of the draft and take up mechanism, in connexion with the knitting mechanism, supported by two separate frames, A, T and also their connexion with the mechanism for producing an equal and simultaneous rotation of these frames. A, T, all substantially as described, whereby there shall not only be no connexion between the frames, A, T, to extend through the fabric, but no projection from the frame, A, to come in contact with the presser, stitch wheels and cam bar, or their respective supports, during the simultaneous and equal rotations of both or either of the said frames, A, T.
