SPECIFICATION forming part of Letters Patent No. 405,645, dated June 18, 1889. i

Applicationled February 7, 1888. Serial No. 263,272. (No model.)

To @ZZ whom, it may concern.-

Bc it known that I, HORACE VYMAN, of lVorcester, county of Worcester, State of Massachusetts, have invented an Improvement in Shuttle-Box Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specilication, like letters on the drawings representin g like parts.

This invention has for its object to improve fancy looms employing shifting shuttle-boxes in order that the shuttle-boxes at each end of the loom may be operated independently yet unerringly in both directions of their movement, the shuttle-boxes at the end of the loom opposite that containing the shuttle-box pattern chain or surface beingl actuated by shafting extended across the loom frame rather than by chains, as heretofore common.

In my invention I do away with shuttleboX-moving cams at both sides of the loom.

The mechanism herein to be described is contrived to actuate a series of four shuttleboxes at each side of the loom, each series being moved independently by or through a prime lever; and by throwing into operation a fulcrum-carrying lever at each side the loom, which may be done when desired, a series of six shuttle-boxes may be operated.

In some classes of fabric it is desirable at times to use two or, it maybe, three, or more, shuttles back and forthalternately for a number of picks, and to do this and not lengthen the shuttle-box chain or surface I have combined with the usual actuating-shaft locatedbetween the shaft carrying the pattern chain vo1' surface and the cross-shaft of the loom for turning the said actu ating-shaf t a controllin mechanism containing a cam which, through intermedi-ate mechanism, shifts the usual clutching-hub on the said actuating-shaft, to thus in usual manner rotate it and the pattern chain or surface in one or the opposite direction, as may be desired. The cam of the -The shuttle-box mechanism to be herein described is an improvement upon that described in United States Patent No. 336,623.

My invention consists, essentially, in a shuttlc-box pattern surface or chain, a shaft upon which it is mounted, reversing-gearing in 0perative connection with the said shaft, and a clutch-hub, combined with a cam forming part of a controlling mechanism, means to rotate it intermittingly, and with means, substantially as will be described, between the said clutching-hub and cam to move the said hub; also in a loom the following instrumentalities, viz: a rock-shaft extended across the loom and provided with fulcrum-carrying levers, means to rock the said shaft positively, two prime levers, each mounted upon one 0f the said fulcrum-carrying levers, a main lever, means to connect it with one of the said prime levers, a rock-shaft having arms and connections between it and the other prime lever, two series of shuttle-boxes and connections between them and the said prime levers, and means to actuate the said main lever and rockshaft independently and positively, substantially as will be described.

Other features of my invention will be more fully set forth in the claims at the end of this specification.

Figure l is a partial front elevation of a loom embodying my invention, the central portion of the loom being broken out and the shuttle-boxes at the lefthand side of the loom being` partially broken away to save space upon the drawings, Fig. 2 is a partial lefthand elevation of the loom shown in Fig. l, the said figure showing some parts omitted from the left of Fig. l. Fig. 3 is a section, but partially broken out, of a loom embodying my invention, the section being taken below the irregular line Fig. 2, the lower part of the shuttle-boxoperating mechanism being omitted. Fig. A is a right-hand end elevation of the loom shown in Fig. l. Fig. 5 is a top or plan View of the shuttle-box mechanism at the left-hand end of the loomframe in Fig. 2, the said parts being omitted :from Fig. 3 to avoid confusion in the drawings. Fig. 6 is a detail showing the gearing between the picking-shaft and the semi-gear employed to intermittingly actuate .the usual.

lifter and depressor-gears for driving the usual toothed gears or cranks of the shuttlebox mechanism. Fig. '7 is a sectional detail in the line ce', Fig. 6, the stud 71 being in elevation. Fig. 8 is a sectional detail in the line 002, Fig. 3,chiefly to show the locking mechanism for the so-called controlling mechanism. Figs. 9 to 14 are diagrams showing the positions of the levers and their actuating Vmechanism employed to move the shuttleboxes so as to place any one of the boxes opposite the race of the lay. Figs. 11f1 and 12*L represent the cranks, links, and levers in positions different from those shown `in Figs. 11 and 12, yet when in the positions 11L and 12L the third and fourth boxes may be reached, as in Figs. 1'1 tov 12. Fig. 15 represents the upper portion of the left-hand end of the loom broken off from Fig. 2, together with a portion of a Jacquard or pattern mechanism, to be described. Fig. 16 represents a similar portion of the right-hand side of the loom, supposed to be broken off from the top of. Fig. 1. Fig. 17 represents the upper portion of the loom broken off from Fig. 1. Fig. 18 is a detail showing the auxiliary main lever and some of its connections andthe fulerumcarrying lever. Fig. 19 shows the stud-carriers, arm, and secondary lever pivoted thereon at the right of the line 01:1, Fig. 5, viewing the front of Ithe loom, together with the rockshaft, which has a second arm to be connected tothe prime lever at the opposite side of the loom to actuate the shuttleboxes at that side of the loom. Figs. 20 and 21 are respectively a plan and rear elevation of a modilied form of controlling mechanism, and Fig. 22 a modification as to the actuating mechanism for the fulcrum-carrying levers.

The mechanism to be herein described is adapted to bring at predetermined times any one of six shuttleboxes in position opposite the racewayof the lay.

Many of the parts employed herein are common to United States Patent No. 336,628, dated February 23,1886 but in some instances the p arts are somewhat differently shaped and differently located from what is shown in the said patent, and so, also, some of the parts are "substantially the same as in United States Patent No. 264,864, dated September 26,1882.

The loom-frame A* is and may be of any suitable shape to support the working parts. The picking-shaft b21), the larger gear T, fast thereon, the gear T', engaged by it and fast on the crankshaft S3, the connecting-rods S2, the lay H2, the pin-wheel D3, (see Fig. 2,) fast upon the crank-shaft Sis at its lefthand end, the. stanwheel D'1, engaged by it, fast on a sleeve rotating upon a horizontal stud fixed to the loom side, the beveled gear D7, fixed with relation to the said star-wheel and sleeve, the actuating-shaft D11, for the shuttie-box pattern chain or surface and having loose upon it beveled gears D8 and D9, each toothed at its inner side to form part of a clutch, the clutch-hub D10, splined upon the said shaft D1'1 and toothed at each endto engage one or the'other of the toothed clutch portions of the said beveled gears D8 or D9, the arm D12, carrying the said hub, the sliderod D13, to which the said arm D12 is fastened, and the gear D15, attached to the upper end of the said shaft D11, are and may be all as shown in United States Patent No. 264,864, referred to, wherein like devices are designated by like letters, except as to t-he picking-shaft, which in said patent is marked b; but in the said patent the shaft D11 is vertical, whereasin the present case the said shaft is placed in an inclined position.

Referring to Figs. 2 and 5, the prime lever 20, having its fulcrum on a pin or stud, 21, at one end of fulcrum-carrying lever 22, the main lever E, the connecting-rod t, joining it with the said prime lever 20, the auxiliary main lever E2 (shown in Figs. 2 and 18) and connecting-rod 24, by which to attach it to one end of the fulcrum-carryiug lever 22, the secondary lever F, having its fulcrum upon a stud near the end of the main lever E, the stud-carriers G G', pivoted at 12 and having, respectively, studs 13 and 14, to act against the secondary lever F, the connecting-rods m and m, the toothed gears g, to which they are attached, the vibrators j', upon which the toothed gears g are mounted to turn,

the connector m2, attached to one end vof the auxiliary main lever, as shown in Fig. 18, and at its other end to the toothed wheel or jack g1, mounted upon a vibrator f1, the studs C C', fast to the side of the loom-frame, the toothed gears a d, secured to the inner ends of the hubs or sleeves, carrying the usual elevator or depressor gears, or toothed cylinders a d for engaging either the upper or lower sides of the like notched gears or jacks g1, &C., arranged side by side, and the intermediate toothed gears b c, loose on studs b c', and the locking or holding plate 6, are all substantially the same as in United States Patents No. 386,623 and No. 281,842, wherein like parts yare designated nearly throughout by like letters. Some of the parts common to the said patents are herein slightly modified as to construction, and the arrangements of the parts are somewhat different from that shown in Patent No. 886,623-as, for, instance, instead of making the elevator and depressor gears which rotate the toothed gears or,

other side of the loom, has att-ached to it alikel fulcrum-carrying lever 22:, Figs. 3 and 4, having a stud 21.*, upon Which is mounted a prime lever the forward end of which is connected in like manner With the shuttle-box rod 41" at that side of the loom.

The main lever E and the auxiliary main lever E2 are mounted loosely upon a stud E', supported in a stand 45 and in a bearing 46, forming part of the said stand, the said stud being secured in the said stand by means of a set-screw 220. (See Fig. 1.) This bearing 40 also serves as the bearing for the left-hand end of a rock-shaft 47, which is extended across the loom to its opposite side, where, just outside the loom-frame, the said rockshaft has attached toit (see Figs. 4 and 19) an arm 4S, Which .by a link t* is attached to a stud at the rear end of the prime lever 20i, mounted on the stud 21* before referred to.

Y The rock-shaft 47, at the left-hand end of the loom, has attached to it an arm 49,Which supports a secondary lever Ff, (see Fig. 19,) like the lever F before referred to, the said lever F* referred to being acted u )on b f studs 13* and 14i, carried by stud-carriers G* Gf, like the stud-carriers G and G before referred to, and mounted loosely upon the same stud 12, but farther in toward the loom side.

The stud-carri er G* has attached to it, near its upper end, a connector mi, and the studcarrier Gik has attached to it a connector mk, each of the said connectors m* and m* being attached to like toothed gears gf, mounted upon vibrators ff, the said g'ears being sub-v stantiallyin line With the gears g, but farther toward the loom side.

The arm 49, rock-shaft 47, and its arm 4S, referredto, constitute, as it Were, a main lever for the prime lever 20* at the right-hand side of the loom, the said parts 49, 47, and 4S differing' from the main lever E only in that the opposite arms are separated by a long shaft or connection 47, of suflicient length to enable one arm, located and operated at one s ideof the loom, to transmit motion to parts at the opposite side of the loom.

Each vibrator has attached to it iu usual manner a connector 7i, which are extended up and attached to suitable fingers, as 7L', which rest upon the pattern chain or surface h2, which may be of any usual construction and of suitable length, the said pattern-chain sur.

rounding the usual pattern-barrel secured to a shaft, as h3, the said shaft having fast to its inner end a pinion htwhich is engaged by an intermediate pinion h5, in turn engaged and rotated by a toothed gear h6, fast on a short shaft sustained by a bearing 71,7, (see Fig. 3,) the said shaft having at its outer end a beveled gear 718, Which is engaged and rotated by the beveled gear D15 before referred to, and which is secured to the shaft D1, which I shall call the factuatingshaft for the pattern surface or chain.

From the foregoing description it Will be noticed that the fulcrum-carrying lever 22, located at the left-hand side of the loom, by

being attached to the rock-shaf t 42 transmits its movements to and actuates in unison with. it a like fulcrum-carrying lever 22 at the opposite side of the loom, and that through the rock-shaft 47 and its attached arms the prime lever 20X, at the opposite side of the loom, is moved from suitable stud-carriers and secondary lever-connections located at that side of the loom Where is located the patternsurface for the shuttle-box mechanism, for it is not feasible nor practicable to have a shuttlc-box pattern chain or surface at both sides of the loom. It Will also be noticed by the above-described arrangements of parts that the motions of the toothed cranks supported bythe vibrators are transmitted to the series of movable shuttle-boxes to place them in positions required Without the intervention of any flexible connections, as has been the case heretofore, and Without the employment of cams, the shuttle-boxes in this my invention being moved With a precision not attainable by the use of such linked chains or other flexible connectors, or by cams such as have been used With a system of three boxes.

It will be noticed that Without the aid of the fulcrum-carrying lever the mechanism is such as to operate four boxes positively at both ends of the loom, the said boxes deriving their movement from the pattern mechanism and intermediate devices located at one side of the loom, each being actuated also independently of the other, and by calling into play the fulcrum-carryin g lever six boxes may be used at either side of the loom.

For Weaving patterns wherein it is desired to employ tWo or more colors of weft back and forth alternately for a number of successive picks, and then again two or more colors alternately for a number of picks, to thus avoid employing a very long chain, some provision must be made for moving the shaft carrying the pattern surface or chain forward and backward alternately. To do this in a simple manner, I have applied to the loom a mechanism which I denominate a controlling mechanisim7 which I willnovv describe. This controlling mechanism consists, essentially, of a face-cam, as 50, fast upon a sleeve placed upon a stud 51, extended from the loom side, the hub of said sleeve immediately at the rear IOO IIO

of the said cam' having attached to it a ratchet-toothed wheel 52, (see Figs. 2 and 3,) and a stop-Wheel 53, (shown separately in Fig. 8,) the said stop-wheel having co-operating with it a holding-lever 54, pivot-ed at 55 upon a stud carried by the loomframe,the free end of the said lever having attached to it a spring 56, (see Fig. 2,) which normally keeps t-he roll 55X in one ot' the spaces in the stop-Wheel, thus holding the sleeve and its attached parts in the position Where it is left by the paWl 57, which engages the said ratchet-toothed Wheel to rotate the cam 50 referred to. This paWl 57 is joined to the upper end of a lever 58, pivoted at 59, the lower end of the said lever, 5S being acted upon by the Vpin G0, carried by a projection of the pin-wheel D3,'(see Fig. 2,) once during each rotation of the crank-shaft, the said lever and pawl moving the cam 50 of the controlling mechanism one step for each complete movement of the lay, except when the said pawl is elevated from engagement with the ratchet-wheel 52 by or through the action of a suitable Jacquard or other pattern mechanism or surface, the said pawl, as herein shown, having attached to it a cord 62, which is extended, as will be described, to a Jacquard mechanism, which 1 have selected to illustrate my invention.

The groove in the face of the cam 50 referred to receives in it a roller or other stud 63 at one end of a lever 64, pivoted at 65, the said lever at its opposite end being connected by a link 66 with a collar 67, fast on the rod D13, the movement of the said lever causing the said rod to be moved longitudinally at the proper times to .engage the clutch-hub D with the clutch-teeth of either of the beveled gears D8 or D9, as it may be desired, to rotate the shaft D1'l and the pattern surface or chain in one or the other direction for any number of picks.

The cam 50 of the controlling mechanism referred to, with its ratchet-wheel and sleeve carrying it, is made removable from the stud upon which they rot-ate, in order that cams of diiferent shape and ratchets with a different number of teeth may be applied and used, that depending upon whether or not one, two, or three shuttles are to be used in succession, and then to be reused by a backward movement of the pattern chain or surface through the shaft D14 and its connections.

The cam shown in Fig. 2 is of such shape as to use two shuttles over and over again alternately, such back and forth altern ate motion continuing as long as the pawl 57 is kept in engagement with the ratchet-wheel; but the alternation of the shuttle-boxes, as described, ceases as soon as the pawl is removed from the ratchet-wheel. The sleeve or hub containing the vtoothed gear d before referred to, which in practice is attached to the usual long` gear employed to'rotate at suitable times the toothed wheels or jacks g, derives its motion of rotation from a semi-gear 70, (see Figs. 6 and 7,) mounted loosely upon a stud 71, attached to the loom side Af, the said semi-gear having fixed to it a'holding-iiange 4, which co-operates with the locking device 6. 1

The hub of the semi-gear is extended in opposite directions and has fast upon it between the said semi-gear and the loom side a toothed gear 72, which is engaged by an intermediate gear 7 3 loose on a stud 74, sustained at the loom side, said intermediate gear 7 3 being engaged and rotated by a gear 74X, fast on the cross-shaft Z720. The portion of the hub of the semi-gear 70 farthest from the loom side (see Fig. 7) has fast upon it a cam 7 3X, which actuates the arm 75, joined at its outer end to the lower end of a locking device 76 for the series of vibrators carrying the toothed gears or jacks, the outer ends of the said vibrators being beveled in opposite directions, (see Fig. 2,) so that the upper end'of the said locking device may engage either bevel at the upper or lower side of the vi-v brator and hold the said toothed gears, carried by the said vibrators in engagement with the long gears referred to, which are employed to rotate them partially and positively in one or' in the opposite direction, that depending upon the pattern chain or surface. Thislocking device 76 is shown as a lever having its fulcrum upon a stud 77 in suitable ears 7 8, attached to the frame-work At. has a slot and a roller-stud 79, the slot embracing the stud 71 and the cam 73 coming into contact with the said rollerstud, to hold the said locking device and lock the vibrators in position,while the long-toothed gears, serving as elevators or depressors, are in engagement with the toothed gears or jacks g, &c., and are moving' the latter gears to effect changes in t-he shuttle-boxes.

The diagrams, Figs. 9 to 14, inclusive, show different views of the shuttle-box rod and its actuating devices, starting with the toothed gears or cranks. The diagrams show each but one toothed gear; but it will be supposed that there are other like gears in line with it. The dotted line connecting-rod is that attached to the auxiliary lever E2, it and the link 24 and fulcrum-carrying lever 22 being also shown by dotted lines. The lever 2O is The arm IOC shown by full lines, and also the stud-carriers G Gr and lever F.

From the foregoing description and the letters on the said diagrams, it will be obvious just what positions the various connectingrods, levers, and carriers will occupy when the shuttle-box rod is to be placed in such position as to place any one of its six shuttleboxes in the linel of the raceway.

The diagrams referred to each have a scale marked off and numbered in like manner from 1 to 6, and the shuttle-box rod in the diagram is made to act as a pointer and to rise and fall with relation to the said scale, to thus show the various positions of the top of the box-rod when operating six shuttles.

Referring to the drawings, Fig. 11 shows -the links, levers, &c., in a position to operate the third box; but the same box may be reached when the parts are in the position shown in Fig. 11a. So, also,Fig. 12 shows the parts in position to reach the fourth box; but the same box may be reached when the parts are in the position shown in Fig. 12a, for it so happens in these two instances that the resultant of these different changes of tion is the same.

Referring to Figs. 3, 4, 15, 16, and 17, the crank-shaft S3, just behind the toothed gear T is provided (see Figs. 3 and 4) vwith a bevelgear 61X, which engages a bevel-gear 62X on a shaft 163x, (see Figs. 4 and 17,) having at its upper end a small bevel-gear 164x, which enposi-y IIO gages a bevel-wheel 165x, fast to one end of the main shaft 166X of the Jacquard mechanism.

The main shaft 166 of the jacquard has attached to it a toothed gear 167x, (see Figs. 17 and 18,) which engages and rotates a toothled pinion 168x, mounted on a suitable stud and having a crank or wrist 169x, upon which is tted a eonnectingrod 170, the upper end of which in turn engages a pin 171 of a crank 172X on the shaft 173x, the said shaft having attached to it two like cross-arms 17 4X, which by links 175 are joined to like slides 176, carrying the usual trap-boards 181 182. The Jacquard needle, through which the cord 155 will be extended, will be actuated in usual manner by one of a series of Jacquard cards 84X, carried by a lantern or other wheel 85X, rotated in usual manner, the said devices being actuated as when in usual manner the jacquard is employed to move the warps to form sheds. Herein the said lantern-wheel is shown as mounted in boxes at the ends of slide-rods 186, actuated by arms 187 ,attached to a rock-shaft 188, having an arm 189 (see .Fig.15) extended backward from the loom and attached by links 190 to one end of a lever 191, which is moved by a cam 192, (see Fig. 16,) secured to the main shaft 166 of the jacquard, said cam acting upon a roller or `other stud projecting from the side of the said arm; A pawl 193 engages usual studs at the end of the lantern-wheel and rotates the same intermittingly.

Instead of the particular Jacquard meehanism herein shown, I may employ any other usual or wellknown mechanism, or any usual, well-known, and suitable pattern mechanism.

If the ratchet-wheel 52 is to be engaged and moved step by step by the p awl 57, then the cord 62 and devices to operate it would be unnecessary. Vhen the pawl 57 is to engage the ratchet-wheel 52,l attached to the sleeve carrying the cam 50, the said arms 52X and 154X occupy their lowest position, as in" Figs. 15 and 17. )Viren the pawl is to be lifted by means of a Jacquard card and needle the lifting-board is caused to engage and move the eord155x, thus lifting the arm 154x, turning the rock-shaft 53X, and lifting the arm 52X, and by the cord 62'the pawl 57 referred to is lifted.

The pawl 57 (see Fig. 2) has connected to it a cord G2, which (see Figs. 15 and 17) is extended upward, where it is attached to the arm 52 of rock-shaft 53X, the said arm being shown as weighted and as projecting in the same direction as the pawl 57, all eo-operating to turn the said rock-shaftv in the direction of the arrow (see Fig. 15) when the cord 155X is disengaged. The cord 155 is extended upward through a hole in the usual guide-board 15G, thence through oneof the usual needles, and through a hole in one of the usual lifting or trap boards, above which it is attached to a top board p, the said cord eration of the Jacquard cards 84 on the nee- 7o dies, so that the cord may be lifted whenever desired. The shaft 53X has one 'of its bearings in the bracket 100` The bevel-wheels DSand D, having clutch-teeth, and the intermediate driven bevel-gear D7, constitute what I call the reversi11g-gearing, and the teeth on the hubs of the gears DS D9, eo-operating with the teeth of the hub D10, constitute a clutch.

Instead of moving the chain-shaft h3, as shown in the drawings, Fig. 2, through intermediate gearing between the reversing mechanism and the chain-shaft, the reversing gearing' can be placed directly upon the chainshaft h3, as shown in Figs. 2O and 21, the pattern chain or surface being moved outwardly from the loom side sufficiently to allowthe beveled gear D7 to be attached to the upper end of the shaft D14 and come between 'the two gears Ds D.

The controlling mechanism can also be placed directly below this clutch-gearing, the lever 64, i'noved by the cam 50 of the controlling mechanism in such modification, engaging the groove of the clutching-hub D10, the pawl 57 for actuating the controlling mechanism being attached to an elbow-lever 57X, which by a suitable link may be .actuated from a crank, eccentric, or cam on any rotary shaft of the loom to vibrate the said lever, the said pawl resting directly upon a pattern-surface, as I). (See Fig. 2l.)

Instead of the fulcrum-carrying lever 22 being iixed tothe shaft 42, it may be ngiountegfiL loosely thereon, in which case as link 24, which movesthe said lever, will move only the lever 22 and not the rockshaft 42, and to move the said rock-shaft and with it the lever 22* at the opposite side of the loom, the said rock-shaft at t-he side of the loom where is located the pattern-surface will have fastened to it an arm 22, (see Fig. 22,) which willbe engaged and moved by a link 24, like the Ioo IIO

link 24, the link 24n being operated in the same manner as the link 24, Fig. 18, and in this way each of the fulcrum- earrying levers 22 and 22* can be moved independently of the other.

In mechanism corresponding in general respects to that herein shown, for operating both the harness and shuttle-boxes of looms, it is old to employ a vibrating locking device which engages with the ends of the vibrators after they have been shifted in position. This I therefore do not broadly claim. It is also old in mechanism for operating the harness of looms to provide the harness-operating levers with double-beveled ends, which ends yare engaged by a vibrating locking-bar, and

inclined projection for engagement with the ends of the vibrators, of the compact an d convenient form of devices herein illustrated for operating the said locking device.

I claim- 1. The shuttle-box pattern surface or chain, a shaft h3, upon which it is mounted, reversing-gearing in operative connection with the said shaft, and the clutch-hub, combined with the cam of the controlling mechanism, means to rotate it intermittingly, and with means, substantially as described, between the said clutching-hub and cam to move the said hub, substantially as described.

2. The shuttle-box pattern surface or chain, a shaft h3, upon which it is mounted, an actuating-shaft for imparting motion to the shaft h3, gearing between the said shafts, clutch mechanism and means to rotate the clutchmechanism gearing, a lever and intermediate connections to move the clutclthub of the clutchmechanism, and con trolling mechanism to actuate the said lever, combined with a pawl to engage the ratchet of the controlling mechanism, means to reciprocate the said pawl, and a pattern mechanism or jacquard, substantially as described, to determine when and for how many reciprocations the said pawl shall engage the said ratchet, as set forth.

3.
