SEWING-MACHINE.

SPEGIFIATION-forming part of Letters Patent No. 288,008, dated November 6, 1883.

Y Application filed February 20, 1883. (No model.)

` county of Philadelphia and State of Pennsyl- Vania, have invented certain new and useful ioA Improvements in Sewing-Machines; and we do hereby declare the following to be afull, clear, and exact description of the invention, reference being had tothe accompanying drawings, which form partof this speciticatiomin which- Figure l is a perspective view of our improvement; Figs. 2 land 3, a plan view and section, respectively, of part-s ofthe same.

Our invention has relation to a sewing-Inachine for sewing together two or three or more strands of round cord to produce a flat braid, and has for its object the provision of means whereby the separate strands of cord are held in position one above the other below the needie, so that the latter will penetrate all of the cords at onestroke, securing them together and forming a flat braid. y

It has for its further object the provision of means whereby cords of diderent sizes, or Inore or less cords of any desired size, may be held in position below and operated upon by the needle to forni a braid of more or less width or thickness.

A still further object of our inventiomwhich is applicable to other uses than those above described, is theprovision of a novel arrangement of feed mechanism whereby a device for guiding or manipulating the material to be 0perated upon may be placed directly beneath the needlebar and without interfering or coming in Contact with said feed mechanism, the arrangement being such. that the manipulating or guiding device may be removed and replaced by another of different construction, or adjusted in any desired manner, without regard to or change of the feed mechanism.

Our invention consists in two upright guideplates having slotted lateral extensions and a top plate covering or partially covering the space between the guide-plates, and secured thereto by a screw and pins, so as to be readily removable therefrom, the wholebeing secured to thecloth-plate of a sewing-machine ofthe .of said guide.

needle-bar, in such manner as to sustain and guide a number oi' round cords, which, being sewed together by the needle and thread, will form a fancy braid,

It further consists in arranging the feed mechanism in front of, behind, or to either side of the needle at such distance that it will be out of contact with such guiding device, and will be altogether disconnected therefrom, and yet will perform its proper functions as well as when placedin the usual position below the needle. A Referring to the accompanying drawings, in which we lhave shown our invention as applied to a sewing-machine of a well-known form, A represents the cloth-plate, B the needle-arm, and G the needle-bar, having the needle c at its end and the usual devices for securing the needle in place at the end of the bar.

D is the presser-foot bar, having a presserfoot, d, secured at its end, the presser-foot, however, being turned away from the needle,

ordinary construction, immediately below the,s

or in the opposite direction from that in which it has hitherto been placed.

E represents the feedplate, which occupies a position immediately beneath the pressenfoot, and works through a slot, c, in the cloth-plate, in the usual manner.

rlhe cord guiding and sustaining mechanism has a position below the needle and in front of the presser-foot, its rear end being within a short distance of the latter, and the needle nf'orking through a hole or slot in the top plate This guide consists of two plates or blocks, H H', having laterally-extend ing flanges h h, provided with slots It It h2 h2, through which pass screws h3 hf, which screw into holes in the cloth-plate, and serve to secure the blocks H H in position thereupon, leaving aspace, H2, between them. rlhe guideblocks H H have their inside corners rounded off, as shownatii, so as to permit of the readyY lwhich they are placed, and by substituting therefor plates of different thickness we increase or diminish the depth of the space H2 between the plates, so as to accommodate cords of greater or less size o'r more or less number.

K represents a cap-plate,whichis placed upon the top of the guide-blocks H H and the plates I I, the heads of the screws k 7a fitting in holes k/ 7c in plate K, the latter being held down upon the guide by the large screw K2 at one corner.

It will be seen that by reason of the slots in the lateral flanges of the guide-blocks the latter may be adjusted toward one another, so as to accommodate cords of different thickness. When it isdesired to so adjust the guide-blocks toward one another, it will be necessary to remove the plateKand substituteaplate having screw-holes closer or farther apart. In lieu, however, of using substitute plates, the plate K may have slots in place of the screw-holes 7c k', which will permit of adjusting` the blocks H Hwithout removing the plate; so when it is desired to increase or diminish the depth of the crevice between the guide-blocks the plates I are removed and replaced by others of different thickness.

The operation of our invention is as follows: The guide-blocks having beensecured in position upon the cloth-plate, the screw K2 is loosened sufficiently to allow the plate K to' be lifted up above the screws 7c 7c and swung to one side. The cords from which the braid is to be formed are then placed in position, one over the other, ybetweenthe guide-blocks H H, their free ends being placed under the presser-foot. The plate K is then replaced and the machine operated in the usual manner, the needle and its thread passingthrough the centers of all the cords, sewing them together and forming .them into a braid. As the braid is fedforwar'd it is laid on its flat side, so as to present a greatersurface to the presser-foot and feed-plateand insure a perfect and regular feed.

l essaies The peculiar arrangement of feed mechanism shown7 while it is well adapted to the work of feeding in connection with the. device described for'forming a flatbraid from a number of round cords, is also adapted to be used in connection with sewing-machine attachments of other kinds, and we do not therefore limit ourselves to the combinationof such feed with the precise attachment shown.

Vhat we claim as our invention is- 1. The combination, in asewing-machine, of a feed mechanism comprising apresser-foot and a feed-plate set apart from the needle,with an attachment set beneath said needle and adapted to hold the material operated upon mental plates secured to the tops of said guideblocks to increase theirheight, and a cap-plate secured upon the top of one or both of the supplemental plates, substantially as described.

4.. The combinationof guide-blocks H H', plates I I, and cap-plate K, substantially as and for the purpose described.

In testimony that we claim the foregoing we have hereunto set our hands this 16th day of February, 1883.
