' To all whom it muy concern I Be it known that ll', FRIEDRICH Moerrz WOLF, of Glauchau, in the Kingdomot Saxony, have invented a new and useful Improve ment in Vea-ving-liachines; and Ido hereby'r declare that the following` is a t'ull, clear, andy exact description thereof', which will enable those skilled in the art to make and use` the same, reference being had to the accompanyr ing, drawings, forming' a part ot' this specification, in which- Figure 1 represents a sectional side elevation lotlmy invention, showing that side of the machine turned toward the operative when at work. Figa-2 is plan or top View ofthe same.A Fi'. 3 isa longitudinal vertical i tached sectional view of the endless apron with blocks to govern the position of the needles.

The objectof this invention is an attachment to looms. calculated to obviate the dinioultiesattending,` trcadle-xnachines or draw-v looms with a large number of heddle-shafts, and to supersede the Jacquard machine, and

vwhich is so arranged that for the production or combined in any desirable manner, also,

without much loss ot' time., "lroadle-maehines could not be worked conveniently with more than sixteen heddle shafts, because itis very dillcnlt with a largcnumber otl shaft-s to prodnce a clean shed, and a larger number tha-nihat'above stated ol' ordinary shafts occupies thegJaeq'nai-d. machine has been employed,

. the in'epnraiion ol"`which'requires much time and expense. Viith both these machines, however, with vthe shai't-.machiue, and with the Jacquard machine it is necessaryto prepare new cardsfor each new ,pattern.,Further -more 4both machines have 'the disadvantage, that if .e certain combinationwith zt-certain pattern or partv 'ofarpattern .does not given goed effect, new cards have to'be'prepared'for vthe whole,`or the combination.fmnst-becor (rented on the cards ata 'greet loss of time. These disadvantages are obvieted by my inin the following:

The inner` end of the lcer E connects by links Iirwith the bellcrank levers M, which have their i'ulcrumon pivots N. Counter-weights M', of suitable l ofthe ordinary construction upto this time i size, are suspended from the lowcrnrms of the L bell-crank, which also connectwith the links i L, and the other perpendicular arms ot' lsaid bell-crank levers form the bearings for the large cylinder 0. The construction oi' this cylinder is similar to that in ordinary weavf4 ingan'aclnes, but it is larger in proportion 5 and provided with larger holes than the ordi- P, ot' the usual construction,and this lantern is'subjected to the-pressnre of the foot Q, which is held down by aspring, lt, and guided vention, the construction of whichV is described I `A A'are two wooden rails, which' support l my machine,'t tnd .to which the cast-iron frame' weight.

Twofpawls, S S?, airnnged in thc usual manner, one above' and the other below the lantern i, serve t impart .tothecylinder the desired rotary nio tion in 'either dii ection. The small cylinder li: s its bearings inici-ers mnwhich have thei i'nlcra on pivots a', proie'ctingfi'rom the outel int-faces of the frame Rend by those arin's,` saidsmall cylinder is move-dup and down in slots b in the side pieces of the frame. The small cylinder is not perforated .with holes; but itis furnished with lanterns b*, .similar to the lantern l ofthe large cylinder, and held `in position by a ioot, lii, in the ordinary man- 'neras abo're stated. .Theobjec't ofthe smallv cylinder is toin'ipart motion 'to the endless chain c', lthe sections ot' which are arranged to carry the movable blocksfci, Which govern. the position ofthe perpendicular wires or pat' i la -cs c, and through them that of the needles and skewers. Said skewers aresituated in close proximity tothe slotted needlesplatedit, lone opposite each. slot in said plate', and they are furnished with springs e, which bea-r against a cross-bar, d, which, together with. lthe lower cross-bar, d', 'forni thelguides for .sad palisades. The springs e have a tendency to pressthe palisades down, and by their action the lower ends oflhe same are always heldin eontact'with the surface of the endless apron, or that ol' the blocks secnrelto the same. 'The needle-plate;v d* is mad of sheet-'iron or other suitable material, and it `is provided with. slots to allow the needles f toy rise and fall. Said needles are held by the-palisades in two horizontal rows, one'above the other,and through the eyes of said V'needles pass the skewers G,l whch are raised by the action; ot' the knives F F in the griff-trame.- 'lhe needle or spring-bong is,

'applied so that the sinallcylinder is forced up, and said levers are 4'provided with slots a2, which form the bearings for a transverse rod, ii, on which the hooksfirotatefreely in eitherdirection. These hooks rise in a vertical directionabove the knife 17 ot' the griiframe, and their lower ends are bent at'right angles and 'connected by a weighted '.'cro'ss-bar, i, whereby they (the hooks) are drawn'oit' from the knife. The' objectof these hooks is to canse the smallcylinder to descend, and'thoreby compel'thc saine totnrn',- and this object is etlected either by ".hzand, by pulling the cord 7c', which is confnectedtoon'e of the hooks, and which is, used' -if ihegpicture is to bechanged-after more "fithan four shoots, or thehooks may be moved `automatically by the .action of the large cylinder on the. rod Z, which is attached to the lowerend of a double-armed lever, 1*', the upper end of which connects by a suitable rod, Z2, willi one of the hooks. `Tl1e rod lextends the pattern is changed. small cylinderis effected by the Daw'ls 0 o` `frame. l? rises. 1

fromthe lever l* yback to the large cylinder, audits point drops into suitable holes in the sides of said cylinder. Usually all these sides will b'e provided with such holes', and suitable slides will be provided to shut 'oit' either one of the holes, andas the cylinder rotate the point of the rod l will c( me in contact with said slide or slides. The. large cylinder makes `one-quarter revolution for each stroke of thc lever E, and whenever it has been rotated far.

enough 'so as to. bring that side in which the` hole has been shutoli' incontactwith the point of therod l, said rod is pushed back,

and by the `action .of the lever l* the hooks l are pressed forward and caused to catch over the knife F.- 'VVhencrcr this takes place the small cylinder is depressed and turned, and The turning ot the catching-over the studs in the lanterns '11* in the usual manner.l It desired, the sin all cylinder lmay be placed above the needles f, and" so arranged with two pawlsv that it can be turned" backward and foiwaird. c', which works outhe small eylin ler,l is composedof a series ofy plates which are so arran ged that they are capable of` holding each a number of blocks (it,4 made ol' font' ditterent heights, and arranged according to the pattern to be produced. (See Fig. 8.) By those blocks the p'alisades c are raised to different heights and the needles fare made to arrange 'themselves in four dit'tlrent positions, according to the pattern, so as to enable them lo drop into the requisite holes in the sides ot the large cylinder.

no further explanation.

For power-looms the 'construction or" 1n y ma chine is substantially the same as above -described, but the whole must be made stronger,

and the axle of the large cylinder O is made.v

partially squarcyto carry an endless chain, 4the number ot' plates of which corresponds to the number of shoots reqniredfor the pattern to be produced, and which .serves to cause the small cylinder b to turn automatically as required bythe design or pattern by its ac -iony on the rod l, which in that case is placed op positeto this additional endless chain instead of to the large cylinder. yThe operation of `this machine and the va ricuseftects produced thereby are as follows: llt the main le'ver E `is depressed or pulled down by the action of the treadle, the grilli By' the action ol' the rod Kj', which connects the grii-.t'raiuc with the working-beam J, one arm of this beam is raised, and thcopposite-arm, together with the. harness-board H, is depressed. The skewers resting on said board sinlcdown with it, and thereby a regular shed is produced, andthe fabric becomes moregeven and unil'orin than by the ordinary'lc in. Simultaneously with i the rising of the `gritlt'ranie by they action of the lever E the lower arm ot' the el bow-level' rEhe chain The harness or shaft arramgei-nentl iseected in the usual manner, and requires klit over theknii'e F', they rise simultnneousl y with.J the griff-freine and the small cylinderjb is deisndes the needles f ere raised and depressed Y mder, and which are provided with :t dii'er 0* so that they 'ztreenabled to meet the -row duced.
