IMPROVEMENT IN BRAIDING-.ATTACHMENT SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same,

To all whom it may concern:A

Be it known that .T JMES M. LYON, of Watertown, in the county of Jefferson, and State of New York, have invented a new and valuable I mp'ovement in Braiders for ,Sewing-Machines; and I do hereby declare 'that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had tothe annexed drawings, making a part ofthis specication, and to the letters and tigures of reference marked thereon.

Figure l, of the drawings, isa top view ot my in.

My invention relatesto sewing-machines, and consists, mainly, in the construction and novel arrangement ot' devices, whereby, on any vertical or needlefeed sewing-machine, braid may be guided to and sewn to the under side of cloth, according to a pattern traced on its upper or visible side.

The letter A, ofthe drawings, designates the upper plate of the braider, usually made ot No. 25 gauge sheet-steel. This plate is square in shape, or nearly so, with rounded corners, and slightly convex, ib'rming a small table, over which the cloth, to which braid is being sewn, will easily glide.

In the centre of this plate is formed an oblong. slot or opening, a., tig. 4. The sides of this slot are parallel and straight; one end forinsan incline plane, a', tig. 5, and the other end has a small semicircular recess formed in it, a, tig. 5. This plate or tableA is riveted, or otherwise rmly secured, to the shank B, tig. 3. This shank is usually made of No. 18 gauge sheet-steel, and generally ofthe form shown in the drawings.

One end ofvthe'shank is slotted in the direction of its length, as at b.

Through this slota thumb-screw, C, works, fastening thefbraider rmly to the bed ot' the sewing-machine.

The shank B is curved or bent upward from each endtoward the centre, so that the action of the thumb'- opening, o, fig. 3, ot'- 'similar shape to the slot in the centre of plate A, but slightly narrower, so that when the -platcs A and B are fastened together, the slot e, being placed immediately below the wider slot-a, will show an edge, d, ou each side, forming a support or guide to the braid, while the needle is passing through it.-

In theedge of the shank B,a notch, @,is cut,being, as it were, a continuation of the slot o, but separated from it by the incline plane 11,011 which the braid slides up to the cloth.

The operation of the braider is as follows: The nppertensiou being made strong, and the lower tension easy, the braid is threaded from the underside of the braider, through the hole e, which isbetween the incline plane n'and'thc upper plate A, the end of thel braid being allowedI to pass over and back of the slot about one-half inch.

The braider is now attached to the machine, so that the slot in it will be directly over the slot in the needle-plate, and the needle will pass down through the' semicircular recess in the front end of the slot, without touching.

The tliuuib-screw is firmly screwed down. The ordinary hemmer-screw will answer every purpose. The shuttle-thread is drawn up, asin ordinary sewing. The cloth, marked on the wrong side, is placed on the braider, with the marked Side up, and the mark under the point of the needle. The presser-foot of' the machine is now lowered, and the sewing performed as usual.

The braid passes up over t-he inclined plane n, along the ledges d d, and, being sewn to the cloth, up over the inclined plane 7, in the direction indicated by the arrows.

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

' The braider, herein described, having table A, elas- Atic bent shank B, set-screw O, needle-hole a t opening into the oblong slot a c, provided with ledges d d, inclined plane 11., and openings 11, e, and e', all constructed and arranged to operate as specified.

In testimony that I claim the above, I have hereunto subscribed my name, in the presence ot" two witnesses.

JAMES- M. LYON.
