It is well knownto employ jacquard mech- .anismfor thepurpose ofcontrolling the exquire'onlytwo rows'ofholes and blanks in tent throughwhich a plurality of carriers are moved so as, for instance,to bring. end'sof yarnshaving different characteristics (e; g. different colours) into positions in which selected pieces orlengths of said yarns'can be withdrawn for incorporation in a fabric;

The present invention'relates to'such mechanism; but ofthe particular type wherein only a fraction ofithe total number of rows of holes' and blanks in each of the jacquard cards used'is. operativeat eachstroke of the card cylinder, and wherein the card cylinder is moved bodily after. each stroke so as to bringa-new setofrows in'the samec'ard into the operative position.

The object of the inventio is to aste jacquard mechanism of the above type which heretofore. a a V 7 According to the invention, the improved will'besimpler and cheaper to construct than mechanism comprlsesa card cylinder adapt 7 ed' tomove up-and-downbelow a number of groups of, relatively movable vertical xmembers, formed with lco opcrating recesses, andthereby actuate selected membersfof said groups, and horizontal wiresadapted to control the carriers,-said wires being associated with said members in such a manner that selected wiresfwhen' located in registering groups a of said recesses, become operative on the'carriersa j Thehof lizontal wires, which are initially set or fsprungso that they tend normally to enter the recesses, are preferably arranged in vertical rows. and associated with an assembly of members which can be moved laterally to pull the horizontal wires clear of the recessedlmembers.

Each group-of recessed members maycomprise an appropriate number: of lightslats, and these slats may be formed or provided with card-engaging parts. which are'bent or setinapairs so that all these: parts can be ar ranged-in two long rows and therefore retheLcards forrtheiroperation. This allows a standard card of; sixteen rowsito, be use'd for eight successive strokes before bringing a new card lntooperatlon.

One forrnwhich the invention can take is illustrated, by way of example, in the accompanying drawings in which g F'g. 1 is an end elevation ofthejacquard mechanism, parts thereof beingomitted for clearness. 11 Fig. 2 is a sectional view of certain of the parts already shown in Fig. 1 and of other parts omitted therefrom. i i i Fig; 3 is a fragmentary sectional plan of thejacquard mechanism, parts thereof being removed for clearness. 1 V Figs. 4' and 5, respectively, are fragmentary views showing details ofconstruction;

Fig 5.16 and 7 are'elevations at right angles to one another of a group of slatsconstitutmg the above mentioned vertical recessed members. l y The jacquard mechanism and associated parts are supportedby a frame 10 ,The carriers to I quard mechanism each consist of a vertical bar 11 provided with a vertical-row of eight be controlled by-the jade PA EN -TO E- stops, consisting of horizontal pins';l2,these 1 pins penetratingthe bar transversely thereof and passing through an elongated slot 13 therein.- At one side of the slot 13a spring strip 14 is secured which is formed withtongues 15 projecting intothe slot18 and bearing against the respective pins 12 so as to impose a frictional drag thereon. The bars 11 are guided top and bottom: by p airsof cooperating plates 16 and 17 supported respectively by the frame 10 and brackets 18 thereon, the bars passing through slots in these plates. Each bar at its top end is formed with a shoulder 19 which normally rests upon the topmost plates 16, 17, thus supporting the bar as a whole. The pins 12 are individually slidable across the-bars into an operative position or an inoperative position which they are shown in the drawings) and are normally maintained in either position by the frictional action of the tongues 15. a V a V The carriers constituted by the bars 11 cooperate with ai'yertically reciprocable hori-' zontal bar, or straight-edge, which is so disposed that, when it is lifted, it would engage, in each carrier, with a pin 12 which, for the time being, should occupy its opera.- tive position, in which it would project into the path of the bar 20. The bar 20 is supported at each end by a block 21 secured to a slide rod 22. The bar20 derives its vertically reciprocating motion from a swinging arm 23 secured to a rock-shaft 24: and connected by a link 25 to a block 26 secured to the slide rod 22. Each carrierll would have attached to its lower end a member (not shown) presenting, for example, a vertical row of dif ferently coloured threads. The arrangement would thus be such that, whenever each carrier should be lifted to a certain extent by the rising bar 20, during each cycle of operations of the jacquard, it would carry the member with it, and the latter would thereby bringa selectedone of the coloured. threads into a position in which it could be engaged by grippers for ultimate incorporation in the fabric being manufactured.

The jacquard proper comprises a large number of horizontal wires '30, groups of vertical slats 31, three assemblies 32, 33 and 34 respectively of vertical rods and a somewhat similar assembly of angle bars 35, called hereinafter a grid (seeFigs. 2 and 3).

The horizontal wires 30, like the pins 12 on the carriers 11, are arranged in vertical rows, therebeing one wire for each pin 12. At the end of each wire adjacentto the respective pin,a loop 30 is formedthrough which passes one of a large number of vertical blades 36 supported by a rigid frame 37. These blades serve as limit stops, or keepers for positioning the wires. In the vicinity of the slats 31, the wires are formed with flats 30 The wires 30 are supported near their ends vertical rows of horizontal rods '38 and 39 respectively mounted inframes 410 and 41. Springs'42 are wound-around the lops 30*, the springs pressing at one end against the blades 36 and at the other end being secured to the loop 30". Normally, the flats 30 of the wires 30 press against the slats 31 and tend to enter recesses therein, said recesses being hereinafter described.

The assemblies of rods and 33, which are respectively mounted in frames 4:3 and 44, are provided for the purpose of setting or springing the wires 30 towardsthe slats 31. The extent to which the wires are set or sprung towards the slats can be regulated by adjusting the frame 1 1 appropriately. In order that such adjustment can be effected, there is provided at each end of the frame 14 a fixed bracket lli through which a set screw 16 is threaded, the said screw 1-6 pressing against the adjacent end of the frame (see Fig. 3). v 1

The third assembly of rods 34 is mounted on horizontally movable frame 47, which is supported at each end by a fixed bracket 48.

Atone end, as shown in Fig. 4, the frame 47 has an arm 19 which is secured to one arm 50 of a bell-crank- lever 50, 51 fulcrumed on a fixed bracket 52. The other arm 51 of the bell-crank-lever is operatively connected to mechanism actuated by a cam which is actuated in its turn by the mechanism (not shown) of the loom. The arrangement is such that, when the arm 51 is lowered by the cam-mechanism, each rod 34: pulls a vertical row of wires 30 clear of the respective slats 31. When, on the other hand, the arm 51 is raised by the cam-mechanism, the wires 30 are allowed to move back against the slats 31 so that they tend to enter the recesses therein. As shown in Figs.6 and 7,the slats 31 are formed with specially shaped recesses 0r notches 31, which are indicated by vertical shade lines in Fig. 6.

The slats 31 are provided top and bottom with extensions 31 and 31, respectively, which extensions are individually guided through fixed bars and 61, the limits of the movement of each group of slats being defined by a fixed pin 62 passing through registering slots 63 in the respective group of slats. The slats are urged continuously downwards by springs 64 interposed between the bars 60 and collars 65 on the extensions 31". The extensions 31" and 31 are twisted so that they are respectivelydisposed in two parallel rows.

The jacquard card-cylinder 66, which as shownin Fig. 2 is disposed beneath the two rows of extensions 31, is associated with mechanism (hereinafter described) whereby the cylinder is traversed step-by-step across the extensions. At each step of the cylinder, which takes place after each vertical stroke thereof, two new rows of holes and blanks in the card C on top of the cylinder are brought into register with the two rows of extensions 31. During each vertical stroke of the cylinder 66, the card C moves into operative relationship with the extensions 31, certain or none of which may be raised in accordance with the arrangement of the holes and blanks in the card C. If no extension 31 in any group of slats 31 is engaged and raised, then the position will be the same as illustrated in Figs. 6 and 7, in which it will be observed that the lowermost recesses of all the slats register in a position in which they can be entered by the lowermost flat 30 of the respective vertical row of wires 30. It will be apparent that, if one or more'of the slats were to be raised, a different recess would be provided for one of the other wires.

Thestack of slats shown in Figs. 6 and 7 is capable of forming recesses at sixteen different levels, but only eight of these levels are of use in the particulararrangement of jacquard mechanism shown, since such mechanism is adapted to control carriers having narangeiof only eight selectors. However,

if desired, thef,slats shown could be embodied in a jacquardgiving a range ofsixteen' selections, instead of. merely eighty The above-mentioned grid constituted by the assembly of angle bars is adapted to be reciprocated horizontally towards; and away from the adjacent endsofflthe wires; The

arrangement is such that if any wire-should have entered a set of registering:recesses, its end will be engaged by one of the: grid bars and the respective Wire will be movedso as-to engage the respective pin 12- and movethe latter into its operative position.

- V The bars 35 are set in a frame .7 O Which-Jis secured at each end to a'slide rod 71 sup-A ported by bearings-72 onthe frame 10. The

frame derives its reciprocating move ments from a rockashaft 3-having at each end a crank 74 coupled by a link 7 5 to a block 76 secured to the rod71. 2

f r In order to reduce the number of 35 to a minimum so that the bars 'willbe adequately spaced, every alternate vertical row of wires30 is cranked at 30? so as to bring the ends of these cranked wires into the same vertical row as the corresponding ends'of the adjacent vertical row of wires;

At the sideof the frame 10 at'whichthe carriers 11 are mounted, there is provided a board or plate 80supported at its ends by arms 811isecured. toa rock shaft 82. The

vertical reciprocations of the bar 92 are derived from' a rock-shaft 951having at each end a crank 96 coupledby alink 97 to a:blo"ck98 securedlto the rod 93. The weight of the bar 92 and the parts carried therebyistaken in some measure by a strong spring 99, one end of which is anchored at 99 to the frame 10 and the other'end of which is attached to a hook 99 on the base of the rod 9.3; Thearrangement of the above mechanism is such thatthe bar 92 receives one vertical reciprocation in' each cycle of operations, during which reciprocation the cylinder 66 is moved against the extensions 31, and certain (or possibly none) of these are raisedlin accordance with the arrangement of'holes and blanks in the card i The mechanism forimpartingstep byestep lateral movements to the card-cylinder includes a cam 100 on a shaft 101 journalled-in the-bar92r The camLIOOhas for its follower "a roller 102 on: the shaft 90, theiroller' 102 being held against thelprofile: of the cam 100 by a spring 103, one end of which is anchored -at-103'= to the "frame 10 and the otherendv of which is attaohe'd to a pin 103 on a part 116 z associated with the card-cylinder. The cam 100 is'actuatedby a wheel 104which is secured to the shaft 101 andwhich is provided with eight circularly arranged pins 104 00- operating with a hook or snick 105 pivotally attached at it stop end to the frame 10.

The pins 104. alsoco-operate with a detent lever 'or stamperi 106 which is pivotally attached at one endto. the bar 92 and which is attached at its other endtothe opposite end of the bar 92 by a spring'107. 'During each cycle of operations of the above mechanism,

one of the pins 104 isengaged by the hook 105 during: the;downward-movement of the bar 92, with the'result that the wheel 1045 and r cam 100 are turned through an eighth of a revolution, and are held in place by the spring-urged lever.106j.- Inconsequence, the follower90 together with thecylind'er 66 are moved one step to the right, thereby bringing twonew rows of blanks and holes in theJcard C-into register with the extensions3l.

' The card-cylinder 66 is provided at each end -w-ith the usual lantern 110, whichcojoperates with'a spring-pressed hammer 1 11 3 for holding the cylinder properly positioned. Both the hammer and its, spring, which is denoted by 112, are mounted in the usual mans. ner in a fitting 113,;whic'h isvattached to a slide-block 11 1 movable in the slide-way 91 and attachedby parts-115,116-tothe shaftf90. i iThe parts; of the mechanism above described are all shown located at one endof the jacquard mechanism; .Itwill be readily understoodthat, where necessary, these parts will be du'plicated at theothei side of" the mechanism.-

With reference to Fig. 5, the parts therein shcwnare located a the far side oi the jacqvard mechanism. The deviceillustrated in Fig. 5, is provided for the purpose of turning the card-cylinder 66 counter-clockwise through 90 at the end of its lateral traverse .to the right in order to bring a new card C? into the operative position. The device shown comprises a hook 121 pivotally ttached at its top end to the frame 10. .The hook is provided with a set'screw 122 adapted'to rest against an abutment 123 on the frame 10, the screw being pressed against theabutment by a weight-124. By adjusting the set screw 122, the hook can be set correctly in a position in which it' will co-operate with'the lantern 110 of the card cylinder when the latterhas moved intoitsextrem'e right handposition. The weight 1241 is 'ad-' justablysecure'd to a rod 125extending from the hook 121 and co-operates with a striker 126 adjustably attached to the fitting113 on the bar92. The-arrangement is such-wthat,

as the cylinder 66 approaches its right hand position, the striker 126 engages the arm 125 during each upstroke of the card-cylinder, thereby moving the hook 121 clear of the lantern 110. hen, however,'the card-cylinder movesinto its extreme right hand position. --the striker 126 misses the arm 125, with'the sembly of vertical rods 34 is maintained so positioned by the cam-mechanism as to keep the wires clear of the slats 31. The ca t cylinder 66 is raised by the shaft 95 and intermediate mechanism and presses up certain, or all, or none, of the slats of each group, and this brings, or leaves, one set oi. recesses 31* in register. The rods 34 are now returned horizontally so as to allow the wires 30 to spring against the slats 81, one wire (i. e. the selected wire) of each vertical row entering the registering recesses. The grid is now moved towards the wires, and the bars 35 thereof engage with all those which have been selected. These wires engage with the corresponding carrier pins 12 and move them into their operative position in the path of the horizontal bar 20. The bar 20 nowlifts and engages the selected pins 12, thus raising the carriers 11 through part of its upward travel.

Thereafter, the bar is lowered, all the carriers coming to rest in their lowermost position, the grid is withdrawn from the wires, which accordingly spring back endwise to their normal position, and the rods 34 are moved to pull the wires sidewise clear of the slats, whereupon the card-cylinder is lowered and the raised slats spring downwards therewith. In addition, the board or plate 80 swings'forward and presses the displaced carrier pins back into their inoperative position ready for the next cycle of operations.

The card-cylinder, after the completion of its stroke, is next traversed by the cam 100 across the slat extensions so as to bringtwo new rows of card. holes and blanks into oper ative relationship therewith. The, above cycle of operations is once more repeated.

The above cycle of operations takes place eight times for each card, there being eight pairs of holes and blanks therein; Thereafter, the hook 121 turns the card-cylinder to bring a new card into operation, and the cam 100 allows the cylinder to move back laterally to its starting position, in which the slat extensions 31 register with the first pair of rows of holes and blanks.

Although it has been stated that jacquard mechanism according to this invention is suit able for use with members adapted to supply thread to grippers, for instance in agripper loom, it is to be understood that the invention is not limited to such use.

It'is further to be understood that modifications in the details of construction and wires operative, mutually co-operating recesses in said members, avertically reciprocatory card cylinder mounted below said vertical members and adapted to actuate selected members in the several groups, and means for moving each selected wire endwise.
