US 2.982 Benjamin W. Bean
Short thread, running stitch, ordinary hand needle, cloth crimped into ridges for passage over the needle
The nature of my invention consists in sewing what is commonly called the “running stitch’ by machinery, the stitch being produced by the combined actions of wheels and pinions in conjunction with a crooked needle.
What I claim as my invention and desire to secure by Letters Patent, is the herein described method of sewing by the combined action of the wheels and pinions forming the undulations or doubles, in connection with the crooked stationary needle, as is fully set forth in the drawings and specification.

US 3.389 George H. Corliss
"Sewing-Engine", Short thread. Similar to Greenough's
I shall claim:
1. The particular combination of mechanism by means of which the rectilinear and lateral movements of the awls are produced viz., the grooved plate e and rectangular lever "d1", in connection with the arm "z", applied to the awl-handle and groove in the standard between the guide-boxes of the awl-handle, the said awls being inserted in the bent arms "y" of their handles and the whole being otherwise arranged substantially as before specified.
2. The particular mechanism by means of which the peculiar movements of the needles are produced and by which they are introduced and drawn through the aperture made by the awls, viz., the needle-shafts "t1" "t1", the same operating, being constructed and actuated, substantially in the manner above described.
3. The peculiar combination of levers which is employed in the needle-shafts, viz., the finger-levers "z1" "z1" and transverse lever "a2", the same being constructed and operating in the manner hereinbefore set forth.
4. The peculiar method of forming stitches after the ends of the threads have been passed through the aperture made by the awls, viz., by confining said ends in a fixed position, as by the pliers "o2" and then drawing the threads out in a doubled form by means of the pulleys "w2", which are made capable of yielding to a given force, in the manner hereinbefore set forth and thus accommodate themselves to the varying lengths of the threads, being for this purpose attached to the tripping-levers "m3" and said tripping-levels being connected with the springs "n3" the whole being arranged and constructed, as above set forth and applied upon endless chains, or operated in substantially the same manner by mechanism of similar character.
5. Making the needle with recesses "h6" "i6" and depressions "a6" "b6" and one point of the needle below the other, as represented in Fig. 7, the same being for protecting the thread in direct proximity with the eye, as described.
6. The particular mechanism which prevents the entanglement of the threads during the progress of the sewing operation, viz., the vibrating levers "x3" "x3", the same being actuated in one direction by a weight or spring or both combined, while in a contrary direction they are actuated by means of the threads which are passing into the aperture and also by their own impetus, the said levers being provided at their front ends with guides and springs or elastic branches which enable them to fasten. themselves upon the threads which are passing out of the aperture and also permit the threads to extricate themselves from the levers at the proper juncture, the whole being arranged and constructed substantially as set forth in the above description. In testimony that the above is a correct specification of my said improvement, I have hereunto set my signature this 6th day of December, 1843.
