US PATENTS IN 1849

DESCRIPTIONS AND CLAIMS OF SEVERAL AMERICAN PATENTS ISSUED IN THE YEAR 1849

 

Sewing Machines. Machines of this kind, until within a few years, have attracted but little attention; but as they are coming into use and are found to answer an excellent purpose, the inventor is ingeniously exercising his skill to improve them. No less than "five patents" have been granted this year for sewing machines.

One of these is a re-issue (US RE 131) of a patent granted some years ago and need not be noticed.

Two of the others are much alike (US  6.099 and US 6.439), differing only in minor particulars. The cloth in each with its edge properly presented to the needle, is secured to a proper feeding apparatus. The needle is placed perpendicular to the cloth in a frame sliding back and forth for inserting and withdrawing it; the eye is near the point. On the opposite side of the cloth is a twisted hook which slides endwise in a direction nearly perpendicular to the needle; as the needle passes through, the thread is caught by the hook and drawn sidewise, forming a loop. When the needle again passes through the cloth, it passes through this loop also and the hook moves forward releasing the old loop and seizing the new thread, forms a new loop passing through the old one. This operation combined produces what is well known as the Tambour stitch.

In another of these machines (US 6.766), the thread is carried through the cloth by a bent needle, with the eye near the point. The shape of the needle leaves a space between it and the thread. A shuttle upon a circular way on the side of the cloth; opposite the needle has in it a bobbin of thread. This shuttle is sharp pointed and curved to adapt it to the way and as it moves around it passes through the opening between the needle and the thread and the needle is then withdrawn, leaving a loop of its own thread around the thread of the bobbin. This, if continued, will produce a seam. The shuttle is driven by two arms from the centre shaft with pins in their ends taking into perforations one in each end of the shuttle and whenever one of these pins approaches the thread of the needle it is raised out of the way and the shuttle is driven by the other.

There are other ingenious devices connected with the machines which I would gladly describe, but I am unable to devote further time to them.

Knitting Needles

My invention consists in the application of a latch or tongue "E" in connection with the hook of the needle. Sweeping freely back and forth upon the center pin "B". I construct my needle in the general form shown in the drawings, of steel or other suitable material and of different sizes according to the fineness of the work, the end at "A" to be mounted with composition as heretofore applied. The latch "E", is constructed in the general form, shown in the drawings, of steel or other suitable material and attached to the needle by a rivet or center pin "B" on which it freely forth; a longitudinal groove is cut in the edge of the needle from the point "B" toward "A" and "C", into which the latch falls in either position. The needle thus constructed is designed to work on the knitting frames heretofore in use

What I claim as my invention and desire to secure by Letters Patent, is:

The application of a latch or tongue applied to the hook of the needle and operated as herein described. March 28, 1848.

Chain-stitch, barbed needle.  

bent needle & hook, one thread, chain-stitch sewing machine

First American patent for a chainstitch machine and first Pressure Foot

Improvement in Sewing Machines. In the above machine we claim as our invention the combination of a needle a and a hook t1, as constructed and made to operate together substantially in the manner and for the purpose of sewing cloth, or any other material or materials capable of being sewed, as specified.

US 6.437                              Jotham  S.  Conant

 Chain-stitch

My improved machine forms or makes what is termed the “chain-stitch" sewing and effecting the same by the united actions of a hook and a needle, as does the machine well known as the “Morey machine", invented wholly or partially by Charles Morey, my machine being an improvement thereon.

I claim the stationary point u, (or any equivalent contrivance for supporting one end of the cloth) and moveable or adjustable clamping slider and point w, in combination with the line or series of points or wires r r r, &c., the whole being arranged and applied together, substantially in the manner and for the purpose as above specified.

US 6.439                                John  Bachelder

Chain-stitch

Two or more threads, continuous feeding device, horizontal table and overhanging arm.  

Bachelder did not manufacture machines, but his patent was sold to Singer.

Improvement in Sewing Machines. I do not intend to confine my invention to the use of an endless belt alone, as a revolving circular table or a cylinder maybe substituted therefor, the points being inserted in or made to project from the curved surface of either of them. What I claim as my invention or improvement, in the sewing machine, is the combination with the endless cloth holder of the curved bar or piece of metal v, for discharging the cloth from its points after being sewed, all as described.

US 6.613                                 James  La Dow

Pegging Machine

What I claim as my invention and desire to secure by letters patent, is the manner herein described of simultaneously punching one or more holes in the leather and driving pegs into others previously made, by means of the awls and punches, arranged as herein described or in any other substantially similar manner.

Second. The manner of supplying the pegs to be driven by the punches, by conveying them from the hopper in a channel which turns them from a horizontal to a vertical position, with the points downwards, ready to be driven into the holes punctured in the leather for their reception.

Third. The combination of the guide point "t", with the set screw "d", for regulating the distance of the pegs from each other and from the edge of the sole.

Fourth. The manner of raising the holder by means of a thumb lever, whether arranged and operating as herein described, or in any other substantially similar manner.

Fifth. The combination of the bent lever, connecting rod and pushers, for the purpose of driving the pegs out of the hopper into the channels which convey them to the punch holes.

And, generally, I wish it to be distinctly understood, that I do not intend to limit myself to the precise form and arrangement of parts herein described and claimed, but expressly reserve to myself the right to modify the same in any way that I may deem advisable, so that I do not change the essential character of the invention.

Lock-stitch, Shuttle Machine

Lock-stitch, shuttle rotating in a lateral annular race. Continuous feed by endless rotating baster-plate.

curved needle & shuttle, Rotary Sewing Machine

Improvements in Sewing Machines. Having thus described our improved sewing machine, we shall state our claims 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 invariably pass through the loop formed in the needle thread, all as herein above set forth. We also claim the pad or washer under the spring arms which carry the shuttle for keeping the filling thread straight, as herein before explained. Furthermore, we claim the arrangement of the wide spring c', c' and bent lever Spring f' f", operating as herein above 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 herein above 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 herein above set forth.
