Patented Mar. 18, 1930 UNITED STATES PATENT OFFICE JACQUARD MECHANISM Application filed January 30, 1929.

This invention relates to jacquard mechanisms for looms and is concerned more particularly with an improved device of this kind, by the use of which a selected figured pattern may be woven in the cloth on the usual ground by means of many less pattern cards than are required in such devices as now constructed.

In the ordinary jacquard mechanisms, a

1 card is provided for each shot of color in the pattern and also for each shot of ground, these cards being cut one by one and laced together in the appropriate order. The ground cards are comparatively simple and easily cut, but in a selected pattern there may be a large number of such ground cards so that the total number of cards for the pattern is very great. It is the purpose of this invention to provide means by whlch shots of ground may be obtained without the use of cards cut especially for that purpose, the elimination of such ground cards substantially reducing the cost of the cards for a pattern and the labor charge for cutting such cards.

In the mechanism of this invention, I employ the usual needles acting on upvstanders and the chain of cards led around a card box in the usual way. The card box is moved toward and away from the needles once for each operation of the loom during the period when the patern is being woven, but when a shot of ground is made the card box and the card in place thereon are caused to remain at rest and the up-standers are controlled by other mechanism. For this purpose, each card is provided with a control area which governs mechanism by which the card box is operated, and in addition certain of the cards are provided with other control areas which govern the weaving of the ground. In the operation of the device during the weaving of figures, the cards operate in the normal way,;but when a shot of ground is to be produced the last card in the figure group is arranged to act on mechanism whichcontrols the weaving of the ground, and this mechanism is placed in condition to be operated on the next operation of the'loom. This last card in the figure Serial No. 336,135.

group is also formed to act on mechanism which throws the card barrel drive out of operation as soon as this last card has been moved away from the needles. Accordingly, the last card in the figure group not only controls the last figure shot but also governs mechanism by which a ground shot may be produced directly following this figure shot. When this ground shot is completed, the card barrel is brought into action again in the ordinary way and the next card in the series controls the formation of the shed for the next shot which may be either ground or figure.

In this mechanism, therefore, it will be ap parent that needles additional to those ordinarily used are employed, these additional needles including a set which determine the ground color and another single needle which determines when the ground needles shall 9 come into operation. The operation of all the needles is controlled by the ordinary cards and the last card in a group which produces a pattern governs the action of the control mechanism and of the ground needles. Instead of having a separate card for producing a ground shot, this shot is controlled by the formation of additional holes in the last card of a group which produces a pattern. Consequently, cards which are ordinarily used simply for the purpose of producing ground shots may be eliminated and the total number of cards necessary for weaving a selected pattern on a ground is substantially reduced and may insomeinstances be cut in half. The cost of the cards themselves and of the labor of cutting them is-thus materially reduced and a substantial saving is effected.

For a better understanding of the invention, reference may be had to the accompanying drawings, in which Fig. 1 is a view in elevation of a portion of a jacquard mechanism for a loom with my improvement incorporated therein;

In these dra ings, only a portion of the iacquard mechanism and the loom with which it is associated is iilustrated, since the jacouard mechanism and the loom are both of standard construction, my invention including additional devices by which the normal action of the jacquard mechanism is modified. I

The acquard mechanism includes upright frame members 10, a pair of which are provided with brackets 11, from which depend pivoted levers 12, in the lower ends of which a card barrel 1?) of standard construction is mounted. As illustrated, the barrel is square in section and the cards 14, laced together in the usual way, come into contact with successive faces of the barrel. One of the hangers 12 for the card barrel is connected to a rod 15 which is acted on by a spring 16 connected one end to the rod and at the other to one of the upright frame members, this spring tending to move the pull rod to force the card barrel to a position opposite to that in which it is illustrated in Fig. 1.

The jacquard mechanism includes a plurality of needles 17, one of which is illustrated in Fig. 1. These needles are arranged in three grou as. The first group contains many needles, the nun'iber depending upon the capacity of the loom, and these needles are employed for controlling the color shots. Each needle is bent to form a pair of notches 18 and in these notches lie upstanders 19, each needle controlling a pair of up-standers. Each rip-stander (Fig. 6) terminates at its upper end in a hook 20 and at its lower end is formed with a loop 21 which extends through an opening in a supporting plate 22, the up-stander being bent back upon itself to form a hook 23 on the free end of the loop, so that when the upstander is in its lowermost position, the hook 23 rests upon the plate 22 at one side of the opening through which the loop of the upstander extends. The two up-standers which are controlled by a single needle 17 are connected in the usual way by a cord 2 1, this cord forming a loop from which extends the cord 25 having the eye 26 through which passes one of the warp threads. Below the eye 26,

ational view the esc apethe cord 25 carries a weight 27 by which the cords 2 1 and 25 are kept fairly taut.

The jacquard mechanism illustrated in cludes the usual lifting knife assemblies 28 and 29, each assembly including a plurality of blades, here shown as eight in number. The upstanders which control the color shots are arranged in sixteen rows in the construction illustrated, and when one or the other of the knives is raised, it engages and lifts certain up-standers in its corresponding eight rows, as determined by the action of the needles under the control of the cards.

As illustrated in Fig. 6, the needles in the figure group lie in eight horizontal rows and each needle extends through a guide plate 30 at its forward end and at its rear end enters the usual spring box 31, in which are provided individual springs tending to force each of the needles to the right as shown in Fig. 6. \Vhen the card barrel is moved toward the needles, such of the needles as lie in front of holes cut in the card remain in their normal position, and the up-standers controlled by such needles occupy a position in which they will be engaged by the knives as these knives lift. As illustrated, the needle 32 lies opposite a solid portion of the card and as the card barrel is moved to the left, this solid portion of the card strikes the needle 32 and thus frees its up-standers 33 from the knives which would normally enthem. The up-standers 33 thus remain in their lowermost position and accordingly the eye 26 in cord 25 controlled by these upstanders remains down. lVhere a hole is punched in the card opposite a selected needle, that needle is not acted on by the card as the card barrel moves to operative posi tion. Accordingly the up-standers associated with that needle remain in position to be en gaged by the knives and since one or the other of the knives is always raised, one knife moving up as the other moves down, the cord 25 associated with that pair of up-standers remains in its uppermost position and the warp thread controlled by these up-standers lies in the upper part of the shed.

The mechanism so far described is standard jacquered construction and it will be evident that in such mechanism, whenever a shot of ground color is required a separate card must be provided for that purpose. This card will ordinarily contain a single row of holes, so that all of the needles, except those lying opposite the holes in this row, will be moved to free their up-standers from the knives. Consequently only the up-standers in one double row will be raised by the knives and the warp threads corresponding to this row of up-standers will be raised, all the others then lying in the bottom part of the shed.

In order to avoid the necessity of providing separate cards for ground shots, I have added to the standard jacquard mechanism two additional groups of needles and up-standers and an escapement mechanism, by which the card barrel may be caused to remain at rest during certain throws of the shuttle. For this purpose, I provide an additional pair of up-standers designated 34 (Fig. 9) and lying at one end of the main group, these Lip-standers being controlled by a single needle 35 and being connected at their lower ends by a cord 36 which extends around a roller 37 on a lever 38 pivoted at 39 at any convenient part of the mechanism. This lever is acted on by a spring 40 attached atone end to a fixed part of the mechanism and at the other to the end of the lever 38 opposite to that in which the pulley 37 is mounted. The needle 35 lies spaced from the main group of needles in the mechanism and a separate space on each of the cards is provided for controlling this needle.

In addition to the main group of needles and the needle 35, there is provided a second group of needles 41 (Fig.8) arranged in an upright row and lying spaced from the main group of needles and the single needle 35. The needles 41 he in an upright row the end of the group of needles 17 and in alignment with the rows of needles in that group. The needle 35 lies beyond the row of needles 41 in any convenient location so that it can be acted upon by the cards. Each of the needles 41, as is true also of needle 35, is provided with its individual spring 42, and the needles 41, through mechanism presently to'be described, control the ground shots in the fabric and operate to produce the same effectas a ground card. These needles, however, are controlled by figure cards so that their operation does not require the usual ground cards.

Each of the; needles 41 controls a pair of up-standers 43 of usual construction, these up-standers being connected by a loop or cord 44 at their lower ends, from which loop 44 xtends a cord up to the end of a crank 46. There are eight such cranks 46, each of which is mounted fast on its individual rod 47 extending across the front of the machine. Each rod carries a similar crank at its other end, and when one of the cords 45 is pulled, rocking one crank, the rod 47 associated there with is rocked and thus raises the other crank. The crank ateach end of each rod is provided with a push rod 48, the upper end of which is connected to latch member 49 mounted at on end to a frame 50. Each frame consists of a pair of side members 51 mounted in suitable supporting members 52 and extending between each pair of side members is a. spindle 53. These spindles are so positioned that when the frame of which they form a part is moved to the left (Fig 2) the spindle will engage all of the up-standers in :1 row in the figure group and free these up standers from their knife blade. Since the up-standers are connected in pairs to a single needle, the action of a spindle on the upstanders in a single row will be transmitted through the needles to the up-standers in the adjacent row. One spindle may thus act to throw off the upstandersin a double row, corresponding up-standers in the two rows being tied together and acting on a single cord 25.

The latch members 49 connected to the spindles extend through slots 54 in a guide plate 55, these slots permitting the latch members to be moved upward to the desired extent while guiding their up and down movement.

The card barrel (Fig. 1) is moved toward and away from the needles by the action of pull rod 15, previously described. This pull rod is connected at one end to one arm of a bell crank 56 mounted pivotally in suitable supporting brackets 57 attached to the frame of the device. The other end of the bell crank carries a pin 58 which extends into a slot in a link 59 on the end of a rod 60 which is reciprocated up and down by suitable mechanism, such as an eccentric, operated by the driving means for the loom. Mounted pivotally on the ring 59 is a book 61, the upper end of which is shaped somewhat like an arrow (Fig, 9) and having undercut surfaces 62 to the rear of its pointed end. One of these surfaces is effective to engage the pin 58 under suitable conditions so that when the rod 60 moves down the hook engaging the pin causes the bell crank 56 to rock, pullingon the rod 15 and thus moving the card barrel toward the needles. In the return movement of the rod 60, the pin 58 is engaged by the end of the slot in the link and thus causes a clockwise swinging of the bell crank 56 (as Seen in Fig. 1) thus moving the rod 15 to swing the card barrel tov inoperative. position away from the needles.

Pivotally mounted at 63 in the brackets 57 is a bell crank 64, carrying a pin 65 at its end, this pin being engageable under certain con- 'itions with one of the undercut surfaces 62 on the hook 61 so that. when the hook is in position to engage pin 65 and thereafter the rod 60 moves downwardly, the bell crank 64 is swung on its pivot. The other arm 66 of the bell crank carries a knife 67 which is engageable with the latch members or hooks 49 connected to thespindle frames.

The hook 61 pivotally mounted on the rod 60 is provided with a tail 68 engaged by a spring 69 tending to swing the hook so as to engage pin 58 on bell crank 56. Connected to the hook is a cord 70, which is connected to the end of the lever 38, which is acted on by the spring 40 previously described. The

spring 40 is stronger than the spring 69 so.

that unless the rod 38 is swungby the action of the knives raising up-standers 34, the

spring 40 will tend to move the lever in a clockwise direction (as seen in Fig. 1), and through the cord 70 this movement of the lever 38 will swing the hook 61 away from the pin 58 and in position to act upon the pin 65. The hook 61 and its associated parts constitutes an escapement mechanism by which the card barrel may be rendered inoperative at appropriate instants in the operation of the loom.

As previously described, the cards, one of which is shown in Fig. 5, are provided with pattern areas for controlling the figure shots. These areas may be designated 71 and the areas are either punched or left solid, depending on the pattern to be produced. In addition certain of the cards are provided with pattern areas 7 2 arranged in a row separate and distinct from the figure areas and in a standard construction there will be eight of tne pattern areas 72 in a row extending transversely of the card. For an ordinary ground shot, a single hole will be punched in the row 7 2.

In addition to the two groups of pattern areas so far described, the cards have another single pattern area designated 73. This pattern area controls the needle which in turn controls the up-standers which act on the lever 38. WVhen a hole is punched in the card opposite the needle 35, the up-standers controlled by that needle are engaged by the knives and this causes the lever 38 to be rocked counter-clockwise (Fig. 1) slackening a". the cord 7 O and permitting spring 69 to move hook 61 to engage pin 58. When hook 61 lies above the pin, the bell crank 56 is moved with the rod 60 as the latter reciprocates, and with each downward movement of the rod 60, the card barrel is drawn toward the needles. If no hole is punched in the card opposite the needle 35, when this card strikes the needle, the needle frees its up-standers from the knives slackening the cord 36. Since the spring is stronger than the spring 69, the hook 61 will at once be swung clear of the pin 58 and when the rod 60 moves to its uppermost position the hook 61 will ride over the pin 65. The freeing of the hook 61 from the pin 58 disconnects the driving means for the card barrel and it remains away from the needles. During this period of inaction of the card barrel, the bell crank 64 is rocked on the next downward movement of the rod 60, causing he knife 67 to engage such of the latch mem-' bers 49 as have not been raised. This movement of members 49 by the knife 67 causes a movement of corresponding spindles 53 and each spindle 53 moved frees all of the uptanders in a double row in the figure group from their knives.

Ordinarily for a ground shot, there will be a single hole punched in the card opposite the row of eight needles 41. Accordingly, when the card barrel moves against the needles, all but one of the needles will be freed from their knives, and all but one pair of the cranks 46 will remain in downward position. A single pair of cranks 46 corresponding to the single hole punched in the card will be raised, raising the corresponding pair of latch members 49. WVhen the knife 67 then engages the latch members, seven latch members will be moved and seven of the spindles will free their corresponding rows of up-standers of the figure group from the knives. One pair of latch members 49 will be clear of the knife 67 and their spindles will remain inoperative so that the up-standers controlled thereby will be engaged by the knives and raised as the knives move up. The effect of a single hole punched in the figure card, causing one pair of the latch members 49 to be raised, produces the same effect, therefore, as would be produced in an ordinary mechanism by a single card having a single row of openings punched therein.

The operation of the device is as follows: As the lever 60 moves down, the book 61 engagin pin 58 causes the bell crank 56 to swing and this draws the card barrel against the needles. Those needles which are opposite openings punched in the card will not be affected by the inward movement of the card barrel, and consequently, the up-standers corresponding to these needles remain in positionto be raised by the knives. Needles which bear against solid portions of the card in operative position on the barrel are moved to free their up-standers from the knives. By punching the holes in the cards in proper position, the desired pattern is obtained. In each card which is part of the figure group, there is an opening opposite the needle 35 and this needle remains in its normal position to the right (Fig. 9) unafiected by the action of the card, so that the up-standers 34 controlled thereby are raised alternately by their knives, pulling on the cord 36 and holding the lever 38 with its upper end to the left (Fig. 1). This permits the spring 69 to maintain the book 61 engaged with the pin 58 and each reciprocation of the rod 60 causes the card barrel to be moved toward and away from the needles, a new card advancing to position in front of the needles with each swinging movement of the barrel. In those cards in which there is an opening presented to the needle 35, there are no open ings presented to the group of eight needles which control the latch members 49.

lVhen the figure has been completed in the fabric and a shot of ground color is de sired. the last card of the figure group has punched in it one or more holes opposite the row of eight needles which control the latch members 49, while a solid portion of the card is presented to the needle 35. )Vhen a card of this type (Fig. 5) is presented to the needles, the needle 35 is moved to the left by the card, slackening the cord 36 and by the spring action causing the hook 61 to ride over the pin 65. At the same time, certain of the latch members 49 have been raised clear of the knife 67, while others lie in position to be engaged by the knife. In the card shown in Fig. 5, there is a single opening 72 in position to control the group of eight needles controlling the latch members. Accordingly, when this card is moved against the row of eight needles, all but oneof these needles will be moved to free their corresponding up-standers from the

knives

28, 29. The up-standers controlled by the single needle which passes into the opening into the card will remain in position to be engaged by the

knives

28, 29, and as these knives are raised alternately, one of the cranks 46 will be raised and the latch. member 49 connected thereto will be lifted clear of the knife 67. On. the next downward movement of the rod 60, the hook 61 engaging pin 65 causes the knife 67 to engage the seven latch members 49 in down position, and the knife 67 causes the corresponding seven spindles 53 to operate and free the upstanders in seven double rows in the figure group from the

knives

28, 29. Accordingly, as the

knives

28, 29 rise, the up-standers in a double row only in the figure group will be lifted and a ground shot will thus be produced.

During this action of the bell crank 64 acting on the knife 67 and the spindle frames, the card barrel remains at rest away from the needles. Since the single needle 35 which brings the escapement into action returns to its normal position at the right, as soon as the card barrel disengages it, the up-standers 34 controlled by this needle are at once restored to a position in which they will be engaged by the

knives

28, 29. hen these knives have reciprocated to the extent necessary to engage both up-standers, the pull on cord 36 produced thereby rocks the lever 38 to normal position and the hook 61 is moved by its spring 69 to engage the' pin 58 on the bell crank 56. The restoration of the hook 61 to pin 58 brings the card barrel into operation again, while the knife 67 returns to inoperative position, the spindles 53 being moved away from the up-standers with which they have been in engagement. On the next down stroke of the rod 60, the card barrel comes into operation in the usual way and if a second ground shot is to be produced the card will be cut with a single row of openings in the ordinary manner. If the third shot is also to be a ground shot, this card will have a solid portion opposite the single needle 35, thus bringing the escapement mechanism into action. The card will also have one or more openings in the group of eight controlling the needles 41 which in turn control the latch members 49.

In order that the spindles may not affect the operation of the up-standers 34, controlled by needle 35, one of these up-standers has a bend 74 so that the adjacent spindle may be moved with-out striking this up-stander.

With this mechanism, it will be apparent that at the end of a group of figure cards, a single shot of ground color may be produced without the necessity of providing the usual ground card for the purpose, this action being obtained by forming the last card in the figure group with one or more openings, so that certain spindles 53 may operate to throw off their corresponding upstanders. If'a succession of ground shots are required, for example eight, only four ground cards will be required, each of these ground cards being so formed as to bring the escapement mechanism and the latch members 49 into action in the manner previously described on the next operation of the loom following that controlled by the card. Accordingly, by this device a large number of ground cards are eliminated, thus effecting a substantial saving both for the cards and for the labor of cutting them. The ground shots may be produced in many different forms by cutting cards with one or more openings in position to control the group of eight needles which control the latch members 49.
