WILLIAM PEARSALL, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO MATTHEW J'. WHITTALL, OF 'WORCESTER, MASSACHUSETTS.

JACQUARD lVIECI-IANISM FOR LOOMS.

To all whom it may concern:

Be it known that "l, WILLIAM PEARsALL, a subject of the King of England, residing at l/Vorcester, in the county of orcester and State of Massachusetts, have invented a new and useful Jacquard Mechanism for Looms, of which the following is a specification.

rThis invention relates to the selecting mechanism or jacquard for a loom.

One object sought to be accomplished by this invention is to provide a strong, simple, efficient and durable selecting mechanism which may be controlled by cards or strips of perforated material.

A further and special object of this invention is to provide means for automatically controlling the motion of the perforated material so that the jacquard mechanism may be made to repeat or reverse a pattern or section of a pattern as many times, or in such order, as' desired to produce a complete design, such for example, as employed in rugs or other fabrics. In addition to this when one piece has been completed upon a loom employing a jacquard mechanism automatically controlled according to this invention, the parts will be left in position so that they will not require resetting or repositioning before commencing the weaving of a succeeding piece of the same design.

ln the accompanying live sheets of drawings, Figure l is a side view partly broken away of a jacquard mechanism, and means for operating the same according to this invention. Fig. 2 is a diagrammatic view of one of the sets of cooperating parts which are employed in duplicate in a jacquard mechanism constructed according to this invention. Fig. 3 is a detail view of a set of operating connections to be hereinafter referred to. Fig. 4e is an enlarged view of the connections for shifting the controlling paper or other perforated material. F 5 is a fragmentary front view thereof. Fig. 6 is a detail view of the levers operated by the chain. Fig. 7 is a detail view of a piece of controlling chain. Fig. S is a perspective view of one of the rolls or spools upon which the perforated paper is wound, also showing a piece of the perforated paper with the perforations therein numbered to indicate the sequence of picks of a repeating part of a pattern.

tary view of a piece of the perforated paper. Fig. l0 is a detail view showing the jacquard connections for shifting the chain. Fig. 1l is a diagrammatic view showing the character of a pattern which may be automatically woven on a loom employing the jacquard constructed according to this invention, and Fig. l2 is a detail view showing the construction of chain which would be employed for controlling the jacquard mechanism to weave a pattern of the character illustrated in Fig. 11.

In weaving rugs or fabrics of similar design upon the ordinary jacquard looms, a large percentage of the total time and labor is .used up in' positioning, repositioning, stripping and replacing the jacquard cards or other perforated controlling material.

n rThe especial object of the present invention is to provide a repeating jacquard mechanism which is automatically controlled to weave rugs or fabrics of similar design without requiring any adjustment or manipulation of the jacquard by the user, and to control the parts so that upon the completion of one rug or other fabric the jacquard will be ready to commence weaving a second rug or fabric of the same pattern.

rlhe amount of labor and the loss of time involved in shifting and manipulating the perforated cards of an ordinary jacquard mechanism can best be understood by an explanation of the manipulations required in weaving a rug of an ordinary typical design. For example, in weaving a rug designed with a border and a body portion comprising three repeats or duplicated pat,- tern sections, the jacquard cards or other perforated material must be repositioned by a loom fixer or other skilled weaver at least six times.

Starting with the loom stripped, it is rst necessary to set into position the set of cards or other perforated material which will weave a border section at one end of the rug. lV hen this has been completed the loom must be stopped, the border jacquard cards removed, and the cards or perforated material for weaving one repeat of the pattern mustv be put in place. Then the first repeat of the pattern has been woven, the cards or other perforated material must be wound back or repositioned to weave the second repeat, and this must also be done before commencing the third repeat, which, in

the design chosen, completes the body of the rug. After the body of the rug has been woven, that set of jacquard cards or other perforated material must be removed from the loom, and the cards or other material for weaving the border must again be put in place to weave the border which completes the other end of the rug.

The jacquard cards or other perforated material employed are necessarily delicate and easily injured, and such cards can be handled only with eXtreme care and by.

skilled workmen. For example, in stripping a loom or removing a set of jacquard cards of that class which use separate flat pieces of card-board, it is customary to wrap each card separately in tissue paper, or to interpose sheets of tissue paper between successive car'ds to prevent injury thereto. In spite of such precautions the perforated materials used for controlling jacquard mechanisms of looms are frequently torn and injured, and Vhave to be replaced and repaired fromtime to time. f

To provide' a jacquard mechanism which will not require a hand manipulation of the perforated paper or other material which controls the same, I provide means for automatically Vshifting the paper in either direction with step by step feeds which will operate to Yautomatically advance or rewind the paper either one step or two steps at a time as desired, and instead of employing successive rows of perforations for weaving successive picks of certain parts of a design (for example, a'repeating part thereof) I employ alternate rows of perforations to weave one-half of a pattern section or repeat when the papier is advancing with a two-step motion in one direction, and I employ the intermeshed or remaining lines of perforations for weavingthe second half of the repeat or pattern section when the paper is being rewound or moved baclr with a twostep motion in the opposite direction.

It results from feeding the paperl or other controlling material either forward or backward, and with either a one-step or twostep progressive motion, that l am enabled to repeat any pattern sections as often as desired, and to weave on the border sections at the ends of the rugs or other fabrics without resetting or manipulating the perforated paper by hand. rlhis will hereinafter be more fullyexplained by a specific description of the operation in weaving a rug of onev particular characteristic design.

The devices which constitute the jacquard mechanism itself have been especially designed to provide a construction of suflicient strength to insure the accurate selection of comparatively heavy parts.

A jacquard mechanism constructed according to this invention has been employed vin practice as the select-ing device of the loom for weaving tufted fabrics which is shown, described and claimed in my prior application for patent, filed Feb. 23, 1904:, Serial No. 194,707, but it is of course capable of general application.

Referring to the drawings and in detail, S in Fig. 1, designates the ordinary shelf or support. Mounted on the shelf or support S are the side frames F which carry the moving parts of a jacquard mechanism constructed according to this invention.

The parts which cooperate to form one of the sets of selecting instrumentalities are most clearly illustrated in Fig. 2. As shown in this figure, 15 designates a paper winding shaft having sprocket wheels 16 for engaging registering perforations in the strip of paper or other perforated material l. By means of the winding shaft 15 the paper is moved back and forth over a shield B which is provided with a depression or groove for receiving the ends of the jacquard needles 17. Each of the jacquard needles 17 is provided at its upper end with a hook for engaging the rod 18 mounted in the vertically movable frame 19. At an intermediate point each of the jacquard needles 17 is provided with an eye for receiving a pusher 20. At one end, the pushers or rods 2O extend through a guide-plate 21, and at their opposite ends, the pushers 2O coperate with ledges or shoulders of a transversely movable pushing plate 71. Cooperating with the pushers 2O and arranged in alinement therewith are spring-pressed. rods 2.3 mounted in guide- plates 24 and 25. Vertically movable at the rear of the guideplate 25 are harness slides 2G. Each of the harness slides 2G is provided with movable pegs or pins 27 which are pushed out by the spring-pressed rods 23, and which are held in adjusted positions by sheet metal friction springs 2S. The pegs or pins 27 are returned to normal position by a laterally movable plate or board 29, and cooperating with the pins or pegs 27 which stand in their protruding or selected position is a lifting ledge or board 80. Connected to all but one of the vertically movable harness slides 2G are lingoes or strings 31 which are connected at their lower ends to vertically movable rack-bars 32 containing the ends of the yarns or worsteds lV, and which may present such worsteds or yarns for use in a tufting loom, for example, as described in my previous application for patent before referred to. One of the vertically movable harness-slides 26 instead of controlling threads or worsteds is connected to operate a pawl which shifts a chain'which regulates the direction and length of the intermittent advance movement of the perforated paper or other controlling material as hereinafter described.

In the operation of a set of selecting devices of a jacquard as thus constructed, the

jacquard needle 17 is first lifted, the controlling paper or other perforated material is shifted, the jacquard needle is allowed to descend, and .if it finds a perforation of the paper, it will assume the position shown by full lines in Fig. 2, while if it rests upon or is support-ed by an unperforated section of paper, the pusher 20 of said needle will occupy the position shown by dotted lines. rllhe pushers are then shifted by the later'- ally movable plate 71, and through the spring-pressed rods 23 push out the selected pins or pegs 27 which are engaged by the vertically movable ledge 3() to raise the desired harness-frames 26. lWhen the harness frames again descend to normal position, the plate 29 moves laterally and pushes back the pins or pegs 27.

The connections for operating the moving parts are most clearly illustrated in Fig. 1. ris shown in this figure, 33 designates a rock-shaft which is journaled in the sideframes F and may be operated from the main cam-shaft of the loom. Extending from the rock shaft 33 are arms 34 which are connected to vertical rods 35 carrying the lifting ledge 30. Journaled in hangers below the shelf or support S are cam- shafts 36, 37 and 38 which make one turn for each operation of the jacquard. Secured on the cam 36 is a cam which operates a lever 39 connected by a link 40 to a lever 4l. At its opposite end, the lever 41 is slotted to engage a pin projecting from a vertically movable slide 42 which carries the paper winding pawls, as hereinafter described. Mounted on the cam-shaft 37 is a cam which operates a lever G2 connected by a link 43 to a bell-crank lever 44. One arm of the bell-crank lever 44 is slotted to receive a pin operating the peg returning` plate 29. Mounted on the cam-shaft 33 is a cam operating a lever' 45 which is connected by a link 46 to an arm 47 extending from a rockshaft 48. Also extending` from the rockshaft 43 are arms 49 which are slotted at their ends to engage pins operating the vertically movable slides 50.

The connections controlled by the vertically movable slides 50 at the opposite sides of the loom are most clearly illustrated in Fig. 3. As shown in this figure, each of the vertically movable slides 50 is provided with an inclined operating section 51 engaging rollers to operate the horizontally movable slides 52 which carry the pusher-plate 71.

Fach of the slides 52 is provided with a rod 53 having an inclined operating section 54 engaging rollers to impart vertical movement to the needle lifting frame 19.

The paper winding pawls by means of which the paper may be advanced either onestep or two-steps at a time in either direction are most clearly illustrated in Figs. 4 and 5. As shown in these figures, the pawl slide 42 is provided with two sets of oppositely facing pawls. The longer pawls 73 and 74 coperate with a ratchet-wheel 96 on the winding shaft 15 to impart two-step movements to the paper, and the shorter pawls 75 and 76 coperate with the ratchetwheel 96 to impart single-step movements to the winding shaft 15. rlhe two sets of pawls 73 and 74; and 75 and 76, are connected by springs so as to normally be drawn into engagement with the ratchetwheel 96. Then required the pawls are rendered inoperative by being held out of engagement with their ratchet-wheel by means of guide-rollers. Two sets ofsuch pawl-guiding rollers are employed, one set being mounted upon a lever 7 8 connected by a link 80 to a lever 31, and the other set of rolls being carried by a lever 79 connected by a link 32 to a second lever 83. The levers 31 and 83 are mounted side by side, and cooperate with a controlling chain which may be of the character employed in ordinary loom constructions. For example, as shown in Fig. 7, the chain may be built up by cross-pins and links, and journaled o n the cross-pins are two sets of operating rolls. Three different kinds of operating rolls are used; risers 90, or rolls of the largest diameter; idlers 91, or rolls of an intermediate diameter; and sinkers 92, or rolls of the smallest diameter. The set of rolls nearest th-e front control the longer or two-step pawls 73 and 74, while the other set of rolls control the shorter or single- step pawls 75 and 76.

The path of the paper is most clearly illustrated in Fig. 1. As shown in this figure, the paper l) may be wound from a roll or spool R between the guide rolls 55 and 56, and over the drum on the windingl shaft 15 down between the winding rolls 5S and 59 to a receiving drum or spool T. The guide rolls 55, 56, 53 and 59 may be turned in unison with the winding shaft 15 by any desired connections, for example, by a chain C, illustrated in Fig. Mounted on the winding shaft 15 is a holding ratchet wheel which cooperates with a roll 77 carried by a springpressed lever to hold the paper in accurate positionas shown in Fig. 4.

Considering now the position which will be occupied by the pawls as determined by the chain, when the levers 31 and 83 shown in Fig. 6, are controlled by a riser and idler on the chain respectively, the pawls will be positioned to advance the paper with av two* step movement at each operation; when the levers 81 and 33 are controlled by an idler and riser respectively on the chain, the pawls will be positioned to advance the paper with a one-step movement at each operation; when the levers 81 and 83 are controlled by a sinker and idler respectively on the chain, the pawls will be positioned to impart a two-step reverse motion to the paper at each operation; and when the levers 81 and 83 are controlled by an idler and sinker respectively on the chain, the pawls will be positioned to impart a singlestep reverse motion'to the paper at each operation of the loom. The chain is mounted upon drums carried'by a winding shaft 93.

The connections for turning the shaft 93 are most clearly illustrated in Fig. 10. As shown in this iigure, 94 designates a vertically movable piece which is controlled from one set of jacquard connections. Mounted on the piece 94: is a pawl 95 engaging the ratchet-wheelQG on the shaft 93.

Coperating with the ratchet-wheel 96 is a spring-pressed holding roller 97 for holding the chain in its adjusted positions.

As shown most clearly in Fig. 9, the row of perforations p for the jacquard connections controlling the winding of the chain' are preferably located at the edge or margin of the paper, and by means of the constructions described each of these perforations n advances the chain one link or step. 25,

The character of the paper or other perforated material preferably employed is most clearly illustrated in Fig. 8. As shown in this figure, two strips of paper are preferably used, and these strips of paper are reinforced vby ribbons `or longitudinal bands which are perforated to engage the registering wheels. Instead of employing two separate strips, a single wide strip may be used, but I prefer to employ two separate strips in order to avoid the use of unusually wide paper. In cutting or perforating the paper to weave a repeat or pattern section which appears more than once on the completed fabric, the successive picks are controlled by every alternate row of perforations. For example, if one repeat of a pattern requires one hundred picks in weaving the same, the perforations of the paper may be of the character illustrated in Fig. 8. That is to say, while the paper is being advanced, the rst fifty picks or the iirst half of the repeat would be controlled by every alternate line of perforations numbered from one to fifty; and during the weaving of the last fifty picks or the last half of thev repeat, the picks would be controlled by alternate lines of perforations numbered from ifty to one hundred VWhile the paper was being wound in the opposite direction. By using alternate lines of perfo-rations to control successive picks of a pattern, and by winding the paper in reverse directions, the paper will be rewound to its starting point upon the completion of a repeat. The pattern chain provides automatic control for the winding` of the paper to produce either the single step or two step advance or reverse winding of the paper required in weaving any of the ordinary rug patterns. This can best be comprehended by a consideration of the operations which take place in weaving an ordinary rug design, such for example, as illustrated in Fig. 1l.

The design of the rug shown in Fig. 11 consists of a border section at each end of the rug, and of a pattern which is repeated three times to form the body of the rug. To weave such a rug with a jacquard mechanism constructed according to this invention requires a chain. of thirteen links. While the paper winding pawls are controlled by the first set of rolls a of the chain illustrated in Fig. l2, the paper will be advanced with a single step movement during the weaving of a border section a.; while the pawls are controlled by the second set of rolls b, the paper will be advanced with a twostep motion during the weaving of a section 7), or the rst half of the first repeat; while the pawls are controlled by the third set of rolls c, a single pick will be woven; while the pawls are controlled by the fourth set of rolls d, the paper will be movedl back in the reverse direction with a two-step motion, and the second half d of the first repeat or pattern will be woven; While the pawls are controlled by the fifth set of rolls c, a single pick e will be woven, completing the rst repeat; while the pawls are controlled by the sixth set of rolls f, the first half f of the second repeat will be Woven; while the pawls are controlled by the seventh set of rolls (7, a single pick g will be woven; while the pawls are controlled by the eighth set or rolls It, the second half it of the second repeat will be woven; while the pawls are controlled by the ninth set of rolls i, a single pick will be woven, completing the second repeat; while the pawls are controlled by the tenth set of rolls j, the first half 7' of the third repeat will be Woven; while the pawls are controlled by the eleventh set of rolls c, a single pick 7c will be woven; while the pawls arecontrolled by the twelfth set of rolls Z, the last half Z ofthe third repeat will be woven; and inally while the pawls are controlled by the thirteenth set of rolls m, the border section lm, of the rug will be woven.

The controlling chain preferably passes around its drum in the form of an endless loop, and upon the completion of a rug, it will be seen that the cham has completed its circuit, and inasmuch as the paper has been wound back into its original position, the parts are ready to automatically commence the weaving of a second rug or piece of fabric of the same design.

It is to be understood that one particular design has been chosen simply for illustration, and that a jacquard mechanism constructed according to this invention can be controlled to weave any design whatever, and at the completion of such design be positioned to automatically repeat the operation.

I am aware that many changes may be made in practicing this invention by those who are skilled 1n the art, that ordinary loom -mechanics may use a considerable variety of instrumcntalities for the automatic control of jacquard mechanisms, and that such automatic controlling devices can be used in connoction with jacquard devices of different types from that which has been herein shown and described without departing from the scope of this invention as expressed in the claims. I do not wish, therefore, to be limited to the construction herein illustrated, but

That I do claim and desire to secure by Letters Patent of the United States is :M
