IMPROVEMENT IN GATHERING MECHANISM Foe SEWlNG-MACHINES.

Specification forming part of LettersPatent No. 42,043, dated March 22, 1864.

To all whom it may concern:

Be it known that I, HENRY S. BROWN, of the city of New York and the State of New York, have invented anew and useful Improvement in the Gathering Mechanism of Sewing- Machines; and I do hereby declare that the following is a full and exact description of the construction, arrangement, and operation of thesame, reference being had to the accompanying drawing, and to the letters of reference marked thereon, making a part of this specification.

Before proceeding to particularly describe my invention, I will premise by saying that the mechanism heretofore used for gathering clothin such a position with reference to the stitching apparatus that the cloth shall be fed just past the needle before the cloth is gathcred, and beyond the needle left free from the pressure of the foot, so thatit can be gathered by the stitching apparatus while in the act of drawing up the loop or forming the stitch; and, secondly, in the employmentof asecondary or additional removable presscr-foot or shoe capable of being placed upon the presserfoot, so constructed and arranged as to be easily attached to or detached from an ordinary sewing-machine, so that when attached it renders the stitching apparatus capable of gathering in the manner hereinafter described, and when detached of sewing a plain scam in nngathe'red work.

To enable others skilled in the art to make I and use my invention, I will proceed to describe its construction, arrangement, and operation, reference being had to theaccompanyingdrawin g. v A, B, and (J are respectively the needle, presser-foot, and feeding device of an ordinary I sewing-machine.

D is the secondary or additional removable pres'ser-foot or removable rest to the presserfoot above mentioned. In this instance it isa piece of metal so formed as to exactly fill the presser-foot, and covering only a portionthereot say about half its lengthand is attached thereto by merely slipping it on and over the end of B; but, if desired, it may be fastened to B by means of a set-screw,the part D to be so constructed and arranged that its lower or bottom side will project below the bottom'of B and extend from the point (I to about the point b, as seen in the drawing; or B andD may be dispensed with as separate devices and a single presser-t'oot so constructed as to operate in like manner besnhstituted therefor. As the purpose of D is merely tochange the position of that portion of the feed mechanism which feeds the cloth in its relation to the position of the stitching apparatus, either of the foregoing modifications, as well as any other mechanical equivalents. may be used or employed for this purpose; but I prefer the arrangement shown in the drawing.

In operating my Improved gathering mechanism the cloth to be gathered is placed between the presser-foot or rest D and the feeder U in the same manner that it would be placed in an ordinary sewing-machine for sewing a plain nngnthered seam. When put in operation the'cloth is clamped between 0 and D and fed along past the needle a distance equal to the length of cloth which is desired to form asinglegather. Then theneedlepassesthrough the cloth, and in, the act of forming the stitch the thread draws that portion of the cloth which has been fed alongpast D, andlies loosely between C and B backward asufficient of the pull of the thread. The fullness of the gathers may be regulated by changing either the tension of the thread or the throw of the feeder, or both, if desired. Though the tensicn 'of the thread must depend to some extent on the nature of the fabric to be gathered, it must of course, under all circumstances, be sufficiently tight to draw the cloth backward, as described.

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

1.The making of gathers by the action of the needle and thread in the manner and by the devices herein described.

2. The gatheringofapiece of cloth and fastening the gathers in place by the action of the stitching apparatus of a sewing-machine when the feeding mechanism is arranged and 0peratedrelatively to the stitching apparatus substantially as herein described.

3. The presser-foct or rest D, or its equivalent, substantially as herein described, and for the purpose herein specified.

HENRY S. BROWN.
