IMPROVEBENT IN MACmE POR IENDING BToCmG'B.

The Schedule referred to these Letton Patent und making of the .im

To all whom it may concern Be it known that I, BiasJAMrs AnNoLmof'East Greenwich, in the county ot'Kent, and State ot' Rhode Island, have invented a new and useful Machine tor )Iending Stockings and other fabrics; and do here by declare the following to be a'fm! and correct deseription thereof,reierence being had to the acrompanying drawings, making part of this siweitiration, and tothe letters and numbers of reference marked thereon, similar letters and numbers heilig used in all the tigures to denote the saine pal/t.. v

In the drawings-,-

Figure 4 shows the inner side of cani U.

` Figure 5 shows the working side of cam R.

Figure ti represents the under side ofthe machine.

Figure 7 is'a horizontal section of ease A, taken through in the. direction of the red line k l." in tig. 2, looking upward.

Figure S show s the relative position ofthe plates a' and b', with the'leversf' j.

Figure 9 shows the hwk-plate c, separate.

Figure 1U shows an eurged view of the rows of stitehes, and the way in which they are connected.

Figure 11 shows an enlarged drawing of the hookplate c, holding the under bight or loop between -thc stitches whilst the needle passes through them.

Figure 1*. shows how the lever V operates on the loose piece on cam C.

Figure 13 is a vertical section of the plates at the top ot' the ease A, taken in same direi-tion as tig. 2.

The nature of my invention consists in unending a hole 4in a stm'king or other fabric, by making successive rows ot' chain-stitches from side to side aeross the aper ture, at themnietiuujoining orinterloekingthese rows by holding the bights or loops between thil stitrlns by means of an xuiparat'us underneath the fabric, so that the needle, in making the next row, shall pass sucressively through these bights, and connect all the rows Ainto one web, joining it to the sides of the aperture by the chain-stitch on one side, and the bigbts, through which the stitches pass, on the other; oml of its main t-atures being` that whenever .von wish tostopthe operation and remove the fabricA from the machine, von have only to draw the ond ofthe yarn through the last stitch, and all will be secure againt ravelling out.

I `will now proccedato doseribethe construction and opl-ration ofthe iiieehzhlisnl and formation ofthe weh.

Fig. l. B is a hollow platform, holdingr the upright ease A, over which'thostocking is to be drawn.

A block. L", shaded red, one end of which holds the needle-bar lcase I), and the other end, the looper-.arm

G, lies in a bearing, t, near the centre of the platform, the main shaft '.l passing.r throughand turning in it.

A gear-wheel, r, on the outer endof the shaft, is driven by a smaller one, q, fastened t0 the crankwheel N. Y

On the other end ofV the shaft is a cam-plate, C, which has a stud, g, on itstaee, which gives motion, up and down, to the needlhar by the connectingbar )L There is a movable piece, 1.', on the back of this plate, which moves the lever H b v moans of the friction-rolle'. Thev needle-har case I) is fastened to the block S, ami has slots in two sides opposite to each other, one ot' which slots is used for the pin in the needle-bar to slide in, and the other is occupied b v the slide Y.

The hmperarm G is pivoted to the otherend of the block S, so as to have the saine rocking mot-ion asthe Yneedle-bar, and has a lmek-and-trwanl motion given to it by the cam R, which has a groove in its face (see tig. iu which the piu p in the louper-arm works.

A joint is made in the looper-arm (see fig. 2) to allow the part ofthe arm that projects over the work to be moved out ofthe wa v,wheu the stocking is put on or taken ott' ofthe case A.

A har, P, is fastened across the under side ot' block S, for the tred-spring t) to press upon. This spring can be swung around, so, as to pressv on either end of the bar, b v the rod f, the outer end of which cutiies up through au opening in the platform, so that it can be operated on the upper sido ofthe machine.

Fig. 12 shows how the cam C an'd lever V operate to pass the hooks e forward and back, to cast 01T one rowol'bights or loops, and tunisien-the other from the bars to the hooks c, to he held in proper position for the needle lo pass through them.

When tinspring 0 is changed from one end of the bar I to the other, to canse it to feed in the other direction, the stud n ou the spring (l strikes against the stud m on the lever-Y, (sec tig. 6,) and throws ther end of that lever against the ram C, so that when the loose pieve k comes around, the lever presses against one en'd of it. and causes the other end to project out and catch theti'iotion-roll iin level' H, (see. tig. 12,) which is dra-wn down, and thus operates the hook-plate e through the eonnreting-iod d, lever I, connecting-lair J, rod k, and wheels b 1I.

After the loose piet-el. has passed by, the lever V is thrown back to place. hy the soiid part ofca-m C, which continues to revolve, without moving the lever H, until the level' Y is again pressed in, in changing the direction of thc feed.

The feeding ofthe nwrdle-har, one `stitch ata time, a certain numherof stitcheseither \va v, is accomplished hv means ofthe rack L placed on the bridge g, and the slide Y on the` wedle-har. (ser lig. 2,) the uee.dIebar being pressed in either direi-tion, aeeouliug to which end of the har l the spring U may heV pressing. As the, needle-har Z goes down, the slide Y is drawn out .of the notch in the rack L, and the spring Mountaining in the rack, allows the needlobar to move the disspaces it occupied when feeding in the other direction,

that, when the pin c'moves out again, it vcornes in con- 'the stocking is drawn over the case A, so as to bring qf in the cam-plate C, and thc loopcr G will bc thrown tance of one notch to one side, (being pressed by spring 0,) so'that, when the slide Y rises again, it enters another notch in ther rack, (sec tig.l 3,) thus feeding the needle one stitch, whenever the hnrdescends,Y

The rack hi allowed to slide on the bridge g the space of one-half a notch, so that, when feeding in one direction, it will bring the needle halfway lwtween thc the purpose ot' which will be explained here.'itter.

Figs. 7, S', El, and 1.3, show the n-latirepositions of the ho0k-plate c, bar-plates u' b', and their connections.

The plate'c lies underneath a' and b', andis moved in and outby the wheels b b working in two short racks, 1 I, on the end ofthe plate.

As the plate c is drawn in, itI carries with it. one of the plates,fsay b', b v pushing against the pins in thel ends of the. levers' ff', that are attached to that-plate, while the other ends ofthe levers push the plate u' out, so that the bars on that plate will be in position to receive the hights of the yan1, and as thc plate c goes out again, it changes over to one side, so as to bring its hooks in front of the bars on plate a', so that, as it goes in, it will catch under the hights on thehars. and hold them as loops for the needle to pass through while making the next row of stitches.

The changing of th plate c from side to side is effected by means of thc guide-plate c', (see tig. 7,) which is fastened to the case A, and a swinging plate, d', which is pivoted to e', and is allowed a certain amount of motion cach "ay, until it brings up against the projections n'ii' 'on the sides of platel e i Guide-plate e' has au oblong recess in through a part ofits length b vl a tongue.

The plate f1' has a V-shaped slot` cut in it, and a pin, c', fast to platel c, projects through both plates eand d'.

Now, as the plate c goes out, its pin c' moves in tht,I direction shown by thev arrow, until it comes against the incline of the plate d', which guides it over to the other side of thc recess in e', carrying with it the plate c. When plate c moves back again, the pin c' passes in the other side of the tongue, in the slot, and throws the plate d' over to the other' side of the plate c?, so

it, divided tact with the other incline of the V-slot, and is thrown over on the other side, thus changing.r thc plate c from one side to thc other, each time itv niovesout and back.

In fig. 10, m' a mw of common chain-stitthes.

The other part ot' fig. l() shows three rows of chainstitches, iutcrlocked h v haring the stitches of thc sec'- ond row (red) pass through the bights ot' yarn between the stitches of the tiist row, and the third row passing through the bights of the second' row.

Fig. 11 shows how the hights o' o' o' (red) are held in the hook of plate c whilst thc other stitches pass through them, and how the bights of the lasty row (black) are caught under the hais of plate a', to be in tum transferred to the hooks thc next time thcv come out and back.

The operation is as follows:

The yam a is drawn from the spool E, and fed down through the platfonn, up through the case A', tothe c vc of the needle as, which is not far from its point. Then the edge of the hole to bc nicndcd just back of the slot p' in the top of thecase. The ntain shaft heilig lturned by means of thc crank-'wheel N, the needle .r will he pushed up through the edge of thc stm'king h v the piti forward by the cam It, to catch the loop formed at the side ofthe needle, as itis drawn hack, and hold it sothat when the needle comes up again, it will pass through it, and make a chanstitch, the needle and looper being moved thc space ot'a stitch to one side, between cach i rise, bythe slideY and its spring h workingin thc rack L, as before described.

Asthe. needle proceeds from stitch to stitch, itwll mrry its Avarn overthe bars, between them, and leave ,a bight of varo on cach bar. 'hcn the needle has rnadexrow of stitches across the hole, the rod fis pushed in, and the spring O thrown over to the other end of the har P,

and the lever V moved by the studs n and m in against the piece l.' on (mm C', (see fi". 12,)-and the lever H will be moved down and up, throwing the plate c ont and hack b v the rod d, lever I, rod J, and bar K moving the wheels b b.

'hen the plate is moved out, it will Vpass overn front of the bars on which the bights of the last rowof stitches are left, and in going hack to place, the hightx will be tmnstened to the hooks, and the needle will proceed to make another row of stitches to thc other side, which will come between the stitches inthe last row in space, so as to bring the needle in frontl ofthe hooks, and through the hights or loops on them. The

sliding ofthe rack L on the bridge, makes this di'er ence of one-half a. stitch, as before described.

dieu the hooks'go out to take a new row of bightts from another row ot' hais, they drop the old bight, and

aslight tension kept on the stocking in front, feedsit over as fast as those loops are cast off.

After making as man v rows of stitches as may be required to cover the hole in the stocking, b v making -a rnotion each way with the rod j, all the bights'or loops will be cast off of the bars and hooks, and the work maybe taken from the machine, only takingcare to fasten the last stitch, in the usual way, with chair ititch work.

It is not necessary to make a row of stitches clear across before changing the direct-ion of the feed ofthe needle, but long or short rows may be made, asthe shape ofthe hole to bc mended may require.

I do not confine myself to any particular loops, as any one that will hold the varn,'so as to make achainstitch, will do, and does notatect the. other parts of my machine. i l
