JACQUARD-MACHINE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 687,223, dated November 26, 1901.

Application led April 30,1901. Serial No. 58,132. (No model I To all whom it may concern/.i

Be it known that we, JOSEPH E. GARLIOK and WALTER J. GARLum, citizens of` the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvementsin Jacquard-Machines for Looms; and 'We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

This invention relates to jacquard appara" tus for looms; and it constitutes an improvement upon the apparatus of this nature patented to us under United States Letters Patent No. 443,235, dated December 23, 1890. In the above-patentedV apparatus, which belongs to the class of machines known as openshed machines, in order to disengage from their suspending grid the elevated hooks that are to drop and when they are down to thereupon disengage them from the grid, whereby their raising and lowering are effected, the jacqu ard-cylinder is made to duplicate its action on the needles at each pick. For various reasons-such as undue expenditure of power, unnecessary wear on the parts, and especially the cards, &c.-this double action of the cardcylinder is not desirable. It is therefore one of the principal objects of the present invention to provide the apparatus with mechanism whereby such double action of the jacquardcylinder may be done away with and the lcylinder have the ordinary single action. Our present machine is constructed so as to be convertible'to operate not only as an openshed machine, but also after the manner of operation of that class of machines having no means for keeping a particular hook stationary at the positionA to which it is called to stand through a series of succeeding picks. The mannerin which we accomplish the above and other objects of the invention will be fully set forth in the following description, reference being had to the accompanying drawings, in which- Figure l is a view in side elevation of thev of the machine, certain parts being broken away to show others. Fig. 4 is an enlarged vertical sectional view of the front portion of the machine, and Figs. 5, 6, and 7 are details of the invention.

The frame of the machine is designated by the reference character a. The stub-shafts b carry at their ends rearwardly-extending cams c, which are rigidly secured on the stubshafts and have curved slots d. These cams are connected with the usual operating-lever e by means of pitmenf.

At the back of the machine is fulcrumed in the usual manner the cylinder-frame g, in which is journaled a card-cylinder h, carrying at one end a star-Wheel fi, which when the cylinder-frame oscillates is engaged by a pawl j', pivoted on the frame, so as to effect a stepby-step rotation of the cylinder. The cylinder-frame is' connected with short levers k, fulcrumed in plates Z, adj ustably secured to the frame by means of links m, the ends of said levers k being iu'turn connected with the cams c by other links n.

At o are journaled adjustable cranks p. One of these cranks is illustrated in Fig. 5, where it is shown asconsisting of a plate q, having a rigid annulartoothed portion 1', with which is adapted tolengagea toothed segment s, held against the plate q by a pin t and a bolt u. By loosening the boltand slightly withdrawing the pin t the segment s may be shifted around the pin t as an axis, so as to change its position relatively to the annulus r, the toothed connection merely aii'ording means for keeping the segment positively at the point to which it is adjusted. To the cranks p i. e., to the segments Sthereof-are connected the upper ends of pitmen lv, the lower ends of said pitmen being connected to vertically-reciprocating rods w, which at their upper ends carry the upper grid x. On vthe top of the grid is arranged to slide horizontally, as in the said patented construction, a grate-frame y, having projections e, which work in slots 1 on the frame of the grid. This IOO grate-frame has grate-bars 2, which are arranged parallel and alternately with the knives 3 of the grid and which are adapted to be carried by the grate-frame close up to the backs of the corresponding knives. The grate-frame carries rollers 4, which work in inclined slots 5 in arms 6, extending upwardly from the frame of the machine, such inclined slotted arms and rollers being adapted to effeet the reciprocation of the grate-frame as the grid moves up and down, being at its rearmost position when the grid'is at its extreme elevated position.

7 designates the lower grid, the same having knives 8, corresponding to the knives 3 of the uppergrid. This grid, as in the case of the patented construction, has a slight Vertical movement, being carried by pairs of togglelevers, to the upper members 9 of which they are pivotally connected. Said upper members thus constitute links between the grid and the lower members 10, each of which is pivotally mounted upon a bolt 11, adjustably arranged in a vertical slot 12 in the frame. The two front lower members are recessed, as at 13, and each is formed with a detentarm 14, which has the shape of an arc described about the shaft ZJ as a center.

The stub shafts b carry downwardly ex tending arms 15, and they also carry pairs of cranks 16, each of which has a slot-and-pin connection 17 with the corresponding arm 15. At the lower end of this lever is adjustably arranged a roller 18, which is adapted to enter the recess 13 in the lower member 10 of the corresponding toggle-lever to buckle the latter. When the roller returns in passing out of the recess, it will engage the member at 19, so as to throw the toggle-les-ers to their original or alined position, and at any point in its movement thereafter it will act as a stop for the arm 14, so as to positively prevent the toggle-levers from buckling.

2O designates anothergrate-frame, which is suspended by links 21 from the lower grid, having grate-bars 22 for separating the series of hooks. The hooks are designated by the reference character 23, they being formed, as described in the said patent, with an upper hooked portion 24 and a lower hooked portion 25, respectively adapted to engage the knives of the upper and lower grids. To the lower ends of the hooks is connected in the usual manner the harness 26 27 designates the usual perforated board which sustains the hooks in their lowermost positions and through which the harness connections pass. 28 designates the needles, each being looped about its respective hook in the usual manner. To the upper front portion of the frame is secured an auxiliary frame 29, in which is arranged a vertical series of horizontal bars 30 and an inclined series of horizontal bars 31, the latter series being inclined outwardly from the frame. In the series of bars 30 are mounted the rear ends of the needles 28, while in the series of bars 31 are arranged hooks 32, which are graduated uniformly in length. Each vertical series of needles is guided for true rectilineal movement by a strip 33, and each vertical series of hooks is separated from its neighbor by a hstrip 34, resting on the bars 31 and having its 1iattened lower end extending into one of a series of notches 35 in a comb 36, constituting a portion of the auxiliary frame. The rear end of each needle is rebent about the strip 33 (see Fig. 6) and is formed with shoulders 37, between which and the strip is compressed a spiral spring 38, normally pushing the needle rearwardly. The rear end of each hook 32 is loopedA into the rebent portion of the corresponding needle, as seen in Figs. 4 and 6. It should be remarked at this point that the lower grid is normally kept in contact with abutments 39 on the frame by springs 40, connecting it with the auxiliary frame 29.

41 designates levers which are fulcrumed between their ends, as at 42, in the sides of the frame d. To the lower ends of these levers are pivotally secured the rear portions of a movable frame 43, in which is arranged a set of inclined knives 44, spaced correspondingly to the hooked portions of the hooks 32. Whenever the levers 41 are moved, an in-and-out movement is imparted to the frame 43. This frame is normally held inwardly, however, by springs 45, which connect it with the frame ct. Said frame 43 also has a slight vertical movement about its pivotal connections with the levers 41. Such vertical movement is adapted to be effected by cams 4G, carried by the cranks 16 and upon the tops of which ride roller-carrying pawls 47, which are normally held against stops 48 on the frame 43 by springs 49. A tappet 50 on the plate portion of the crankp is adapted to engage the lower end of each lever 41 to force the frame 43 outwardly. In order to oscillate the cranks p, so as to raise the upper grid 0c and move the tappets 50 against the levers 41, a roller 51 on the pin t of the plate qof each crank is arranged to work in the slot CZ of the corresponding cam c. The roller-carrying pawls 47 being adapted to slip ott the cams 46 in the manner and for the purpose hereinafter set forth in the description of the operation of the mechanism, so as to permit the springs 45 to draw the frame 43 inwardly, we provide the upper grid-frame with arms 52, carrying rollers 53, against which when the upper grid drops the npper ends of the levers 41 may impinge to throw them rearwardly, and consequently throw the frame 43 slightly forwardly, its pawls snapping back into the position where they ride on the tops of the cams 46, so that the frame is thus reset.

In describing the operation of the machine the initial position of the part-s will be assumed to be that shown in Fig. 1, where the upper grid has been moved to almost the limit of its upward movement, where the selecting mechanism-Mz'. e., the card-cylinder and its IOC IIO

accessory parts-is thrown against the needles,pressing some of them, and consequently the hooks to which they are connected, forward, and where the knife-frame 43 has been set at the position shownin this figure upon an oblique movement thereof in an upward outward direction eected by the combinedv actions of cams 46 and the tappets 50. At this time the grate-bars have been pushed against the backs of the hooks, thereby holding them securely on the knives. The action of the selecting mechanism, therefore, is to dislodge the hooked portions 25 from the knives 8. The inner end of the lever e now proceeds to complete its upward movement, whereupon the further turning of the stubshafts b forces the rollers 18 inwardly to buckle the toggle-levers and effect a slight lowering of the grid 7, so as to insure those hooks which are pressed by the selecting mechanism being disengaged therefrom. Also at the completion of the movement the knifeframe 43, which has been set by the action of the tappets 50, and also, it may be here remarked, by the cams46, which tend to raise it, drops, its roller-carrying pawls 47 having passed off the rear ends of the cams 46. Having dropped, its knives will engage such of the hooks 32 as have been pushed back with the corresponding selected needles, thus holding the needles back independently of the action of the selecting mechanism. Hereu pon the stub-shafts begin their reverse movement, which first acts to reset the grid 7. As the stub-shaf ts b rotate the upper grid oc is lowered through the parts connecting it with the cams c, while the selecting mechanism recedes through the action of the parts connecting it with the cams c. The reverse turning of the cranks p consequent upon the lowering of the cams c and pitmen o causes the tappets 50 to retract out of engagement with the levers 41, whereby they heldv the knife-frame 43 forwardly, whereupon the sprin gs 45 act to draw the knife-frame back, so that the levers 41 stand almost vertical. Meantime the upper grid x has lowered the hooks detached from the grids 7 till they rest upon the bottom board 27. As the grid reaches the Vlower eX- treme of its movement the upper ends of the levers 41 are engaged by the rollers 53, which thus push said upper ends rearwardly, with the consequence that the knife-frame 43 is forced forwardly again, its roller-carrying pawls 47 snapping over the rear corners of the cams 46 to the position thereof illustrated in Fig. 2 and ready to be reset by the levers 41 and cams 46 at the position shown in Fig.

2. The movement of the knife-frame 43 at this time is simply a horizontal sliding one on the auxiliary frame 29. This forward m0- tion of the knife-frame effects a redrawing on the hooks 23,which instead of turning upon their top hooked ends as fulcrums have their.

fulcrums at their lower ends on the bottom board. The effect of this action is to dislodge their upper hooked portions from the upper knives, which are free to move now that the gate-frame y has been shifted by the inclined slotted arms 6 to the position shown in Fig. 2. A continuation of the operation of the machine would be from this point on simply a repetition of that just described. It should be remarked, however, that at the beginning of each rotation of parts the oblique upwardand-outward movement of the knife-frame 43 causes the hooks 32, which it held, to be detached from it.

By adjusting the bolts 11 in such manner that the -lknives 8 of the grid 7 will be elevated above the lower hooked portions of the hooks 23 this lower grid may be thrown out of action. The elfect will be to convert the machineinto the ordinary j acquard-machine, all the hooks normally resting on the bottom board and only such as are not actuated by the selecting mechanism rising with the upper grid. The roller 18 should at this time be removed, so as not to interfere with the arm 14. Moreover, by chocking up the knife-frame 43, leaving the lower grid in its operative position, said lower grid will act as a means for normally supporting all the hooks at the up position, such only of the hooks as are selected being permitted to drop. This class of jacquard mechanism is suitable for weaving carpets. ends of the hooks to their proper seatingpoints and confine them when lowered against material movement, we provide partitions 54, which in cross-section have a tapered shape, as seen in Fig. 1. l

55 designates a leveling-lever, the same loeing fulcrumed in the frame at 56 and having a flexible connection 57 for operating it. Its upper end is substantially T-shaped andbears against the grid 7, which it is adapted to press rearwardly under tension of the springs 40,

In order both to guide the lower IOO being carried by the links 9, which turn on g their pivotal connections'with the members 10, which form with them the toggle-levers. The grid may thus be thrown o ut of position, so that all the hooks may be lowered to the bottom board, and thus leveled.
