US PATENTS IN 1850

DESCRIPTIONS AND CLAIMS OF SEVERAL AMERICAN PATENTS ISSUED IN THE YEAR 1850

 

Knitting Machine. Patents have been granted for "a knitting machine", for improvements in the manufacture of rugs, folding cloth, shearing cloth, pressing hats and for other miscellaneous purposes.

Sewing Machines. No less than "seven patents" have been granted within the last year (1850) for improvements in sewing machines ; it is but a few years since these machines were introduced, but as they are found to be useful, inventive genius is already directed in no small degree towards them and important improvements may be expected. In one of these machines, the needle lies in a groove made in the face of a straight rack and is held in this position. A pinion works into this rack upon which the cloth is laid, the pinion being at the point of the needle. When the pinion is turned, it at once crimps and carries forward the cloth upon the needle and discharges the cloth by a reverse motion with the seam sewed. The eye of the needle is near its point. In another of these machines, the cloth is placed upon the plate of metal lying over an opening in the table and perforated for the passage of the needle. The needle is forced through the cloth and the plate, by appropriate machinery. The thread is placed under the plate upon a bobbin and when the needle is down, by an appropriate motion of parts in connection with the bobbin, the thread is thrown round the needle, which has a notch to hold it and is drawn through as the needle is withdrawn and forms a loop on the upper side. The cloth is then fed forward and the needle is again forced through the cloth and plate and through the last mentioned loop. The thread is again wound upon the hook of the needle and drawn up through the cloth and the loop through which the needle previously passed and by a continued repetition of these operations, the seam is perfected.

Several of these machines make the seam with "two threads", one of which passing through the eye of the needle (which is at its point), is at every stitch carried through the cloth, forming a loop on the opposite side. A shuttle having a thread passes through the loop and as the needle returns its thread, is drawn down upon the shuttle thread which prevents it from being drawn through. I cannot go fully into the details of these machines; they are adapted to various circumstances and make their seams by a variety of stitches.

US 7.296                             David  M.  Smith

Running stitch, short thread

Improvement in sewing machines. What therefore, I claim as my invention, is the herein before described disposition of the thread eye of the needle, (that is to say, the said eye, being placed near the point of the needle) in combination with the afore described manner of supporting the needle and applying it to the machinery which produces the corrugations or foldings of the cloth, not meaning to lay claim to the combination of a needle and gears or other analogous contrivances for producing sewing, as the same have heretofore been applied and used, but meaning only to claim my improvement as constructed and made to operate, substantially as above specified.

US 7.369                                 0.  L.  Reynolds                               

Chain-stitch

Improvements in sewing machines. What I claim as new in my invention and desire to secure by letters patent, is:

Firstly. The adaptation of the bearded needle (a) such as is used in knitting or stocking frames, in combination with the manner of closing the beard or hook thereof previous to drawing it back with the thread, to prevent the point tearing the cloth, by passing it through the hole (v), in the plate (t) in the manner substantially as herein described.

Secondly. The combination of the spring thread leader or guide V, the arched spring (k) and the friction roller (j) for the purpose of leading the thread under the point of the beard of the needle.

US 7.509                                 Joseph  Hollen

Knitting Machine

What I claim as my invention and desire to secure by letters patent, is:

First. The projecting and withdrawing the needles separately and singly, with their arrangement as described, by which I am enabled to knit closer work with stouter needles, substantially as described.

And secondly. In combination therewith, I claim the combination of the jack, the sinkers and depressers, substantially as described.

Thirdly. I claim the thread bearer (V) having an extended sideway motion to and fro at each stitch, by which it lays the thread across the needle at each stitch and returns with it to be ready for the next stitch.

Fourthly. I claim, the spring vice for regulating the supply of thread to the needle opened by the rod (w) substantially as described.

Fifthly. I claim the particular arrangement and combination of the several parts of the machine, by which their various motions are derived from a single crank and screw thread, substantially as described.

Chain-stitch

hooked needle, one thread, chain stitch sewing machine

Improvements in sewing machines. What I claim, is the hook Z, the surface a, the tube or holder s and thread carrier e, working, substantially as above described.

US  7.659                               John Bachelder

Chain-stitch

Improvements in sewing machines. My machine makes what is called the "chain stitch" that is to say, a loop within a loop a succession of loops. I do not claim to have invented the stitch. That was made by hand before the invention of any machinery for sewing and is also made by Morey & Johnson's (US 6.099) and Reynolds (see the above patent ) machines.

What I claim as my invention and desire to secure by letters patent, is the machinery herein described, for making the stitch, viz: the combinations of the hook v, the plier w and needle l, as constructed and made to operate together, substantially as described.

Lock-stitch, vibratory shuttle pointed at both ends, feed-bar

Vibrating Shuttle Machine

Improvements in sewing machines. What I claim as my invention and desire to secure by letters patent, is forming a stitch by each throw of the shuttle and corresponding motion of the needle; that is to say, making one stitch at each forward and another at each backward motion of the shuttle, this being effected by the needle, in combination with the shuttle, both constructed, arranged and operating as herein described, or in any other mode substantially the same.

Second. I claim the combination of the sliding bar Q, the plate r the feeding plate V, the spring W, the screw t, the lever R and the clamping plate T, for holding and feeding the cloth to the needle and regulating the length of the stitch, in the manner herein described or in any way substantially the same.

Improvement in Shuttle Motions in Looms

I claim the boxes P, P1, oscillating upon fixed points p, p1 and having the flat bar springs Q, Q1, attached to them, in combination with the chains c, c1 and the regulating screw d and nut e for giving a more free and easy motion to the picker staves and for the more effectually controlling and graduating the amount of pick.

Short thread-stitch and back stitch

Improvements in sewing machines. The object of my invention is to produce either what is generally termed “stitch and back stitch’ sewing, or ordinary stitching. 

What I claim as my invention, is the combination of two needles, two thread guides and a cloth holder, made to operate together substantially, in the manner and for the purpose as herein before set forth. And I also claim the improvement of making the needles with springs and applying mouth pieces or pressers to them and on each side of the flange of the base plate, the whole being substantially as above described.
