Be it known that I, W. ST. GEORGE ELLLOTT, M. D., of Morristown, in tbc 'county of Morris, and State of hier' Jersey, have invented non` and useful mpro'vements in Sewing-Machines, and that the following description,

when in connection vwith the accompanying draxrings,vhereinai`ter referredto, forms a iull and exact specifica tion of the same, wherein I have sot forth the nature and` principles of iny said improvements, by which my invention may be distinguished from, all others oi'ra. similar class, together with such parts as i claim, and desire 'tohave secured to nic by Letters Qlatenti` Y,

The improvements in serving-machines embraced in the present invention principally consist in the con1 struction and arrangement oi' the feed-iuiechanism, as willzbe h creinaftcnmore fuiiy described.

In the accompanying platos et drawings my improvements in sewing-machines are illustrated- 'Figure 1, plate 1, bcingfa side elevation Aof reserving-machine constructed accordngthereto.

Figure 2, plate 1, a horizontal section taken in the plane of theiinc a: .'c, iig. 1.

Iiigurc, plate 2, a transverse vertical section taken. in the plane of the line yy, iifan, showing the feed:

mechanism in red lines, as .hrownvup end oi of the clothfplate to the machine.

Figures 4 and 5,.',platc 1, views of the shuttie, the' one a side view, and the other a section in the direction oi' its length;

A; in the drawings, represents the clothplate to .the sewing-machine. "This clothplate` is secured to a stand or pedestal, B, by which it is supported, and is provided with an upright or arm, C, that is extended over 'the cloth-plete, und carries the mechanism for operating the needle D to the machine. E, the feed-mechanism, which is shown as arran'ged to operato upon the upper surface of the cloth, and in the construction, as well as -the arrangement of its parts, isias follows: F is a curved or ben-t arm, hung so as to turn or swing around by e sloeveor collar, G, fixed at its upper end to and upon the downward-projecting picco or extension H of the farm C, hereinbef'ore referred to, through which ann plays the needle-.bar I of the machine. This arm F, by its curved shape, extends doivn. und toward the clothlplatc, where it terminates with a foot-piece, J, on which runs and playsi'orward andbaclcward the feed-surface or'bar K, operated by und through the arrangement-0 mechanism to be new described.. This feed-bar K is fixed to the lower en d of a lever, L, hung upon a Fulcrumpin, a, ofthe curved arm F, and connected, at its upper end, M, with a curvedshaped or bent lever, N, also hung upon a fulerum, b, on the armF, and extended in to the plane of movement of the collarjO to the needlebar I, so that when thcfsaid needle-bar moves upward, such collar will abut against said lever N, and, swinging` it, impart-tho requisite movement to the feed-har K to carry or feed the .cloth along upon the cloth-plate. The Jlever L is provided with a spring, P, tobringit back after the bar has ceased to operate it, and when the 'needle is on its downward n xovemcns, and thus to bring the feed-'bar b ack into position for again 'feeding the cloth forward by the upward movement of lthe lever N, and consequently to increase or decrease tbe amount of 'feed to the cloth upon each-upward movement ofthe needle-bar.

As the feed-mechanism is arranged, through 'its' curved arm, to -swing upon the extension H, it is plainly. Aobvious that the feed-bar, arranged to move en. its foot-piece J, can. be brought into position to operate in unf,t

desired'line or-direction, according'as may befound necessary-o1' desirable in stitchin'gor sewing the material; the'arm N, through which.tbc feed-bar is-ope'reted, being always in position for being operated upon bythe l colin: 'to the needle-har.

B, ithe race for vthe shuttle, consisting of parallel bars S, that at each end are hung upon cross-rods T tired in the frame to the' ,cloth-plate A of the machine, hereby it can bo moved either toward or away'frol the plane of movement of the needle through the.clothplate, either more or iess, as may be found necessary to` bring the said shuttle or other under-thread carrier which is hung thereon into position for operating, in con p negation with the needle, toform the stitches in the cloth. The shuttle Vis provided upon opposite sides with vlo'ngitndinz-1l. grooves c, which fit and slide upon the inside edges 'of the parallel bar s S forming the race R.

AThis shuttle is moved backward and forward by means of -a co'nnecting-rod,-Y2, pivotcdat one end, cccentricaily,

to a disk upon a driving-shaft, Z, and at the opposite end to` a carrier, X, arranged to move upon a guide, Y, bclorvthe shuttle-race. The shuttle ts between thearms of .the carrier, as shown in iig. 2. A", n spring-arm fixed to shuttle-race R, in position to throw the loop on thohead or point of tlxe shuttle ol of the sameas tllo shuttlemoves forward. The shuttle V is mode open npon its upper side, so us to allow the boblrin or spool -B2 to beinscrteal and removed 'without necessitating the removal of 4tlm shuttle from thc race.`

Having thus described my invention, I claim ns ne\.v,'and desire to secure by-Lettors Patent- The elurveil arm I", having the presser J, pivoted lover L having feed-foot K and arm M, odjnstnble bent lever N und spring P, in combination w'th'the sliding sleeve G, needle-bar I, and collar O, all constructed and arranged to operato as herein .shown and described.

The above s'pecieation of my invention vsigned by me, this 20th doy of July, 1867.
