JAceUARD-MACHINE FOR Loolvls.

SPECIFICATION forming part of Letters Patent N o. 651,120, dated June 5,1900. Application led September 17, 1898. Serial No. 6934146. (Ilo model.)

following is a specification, reference being had therein to the accompanying drawings.

My invention relates to jacquard-machines of that class in which two pattern cylinders or prisms are employed 'for cooperation with,

the needles, each of such pattern cylinders or prisms having it-s own pattern and the two pattern cylinders'or prisms being brought into action in connection with the needles alternately. It is customary to employ this arrangement for weaving goods having end borders or cross-stripes'at intervals, one of the pattern cylinders or prisms carrying the pattern for the border or cross-stripe and the other carrying the pattern for the body or intervening portion of the goods.

The invention includes various improved and novel combinations-of parts, including devices whereby to bring automatically ther respective pattern cylinders or prisms into action alternately at the required times in the working of the jacquard-machine.

The invention will be described first with reference to the accompanying drawings, in which latter .l have represented one embodiment thereof, after whichl the invention will be particularly pointed out in the claims at the close of this specification.

Figure 1 of the accompanying drawings shows in side elevation certain portions of a jacquard-machine of the class aforesaid with the said embodiment of my invention applied thereto, only such parts being represented as are required in order to clearly indicate the nature and relations of the invention. Fig. 2 is a view in vertical transverse section of a jacquard-machine of the said class, showing certain of the working parts thereof. Fig. 3 is a View showing certain parts in plan. Figs. 4 and 5 show details.

In the drawings, 7l 71 designate certain of the hooks or hooked uprights of a jacquardmachine, the rest of the series being omittedI for the sake of securing simplicity and clearknown character.

ness. l and 2 designate certain needles of the series of needles engaging with said uprights 71 7l, the greater part of the said series of needles being omitted for the reason just stated. The needles 1 2 are arranged and supported in usual manner and engage with the stems of the uprights in customary fashion, the opposite ends of the said needles being supported in stands l2 and 15, of well- 16 designates a pattern cylinder or prism arranged to cooperate with the said needles 1 and 2. Around the said pattern cylinder or-prism 16 a series of perforated pattern-cards (not shown) is intend ed to pass in practice, the said pattern-cards being presented successively against the ends of the needles 14 and 2 by the operation of the pattern cylinder or prism, as will be understood.

The invention which is about to be described may be utilized in connection with either a single-action jacquard-machine or a double action jacquard machine. I have illustrated it as embodied in a double-action jacquard-machine-that is to say, in a jacquard-machine having two sets of moving grid-blades 72 72 and 82 82, respectively, the said griff-blades being mounted in the griffframes 7 and'8, respectively, and the said griff-frames being applied to guide- rods 18 and 19, which latter are arranged to slide as usual in guides or bearings provided therefor on the frames of the jacquard-machine, the said guides or bearings, however, being omitted from the drawings for the sake of clearness. Movement is communicated to the griffs through rods 9 and 10 from suitable moving parts of the mechanism, (not shown,)

and thereby in usual manner the two grids are raised alternately.

1l designates the usual bottom plate. v A second pattern cylinder or prism is'shown at 17, and around the saine is intended to pass in practicea second set of pattern-cards. (Not shown.) For convenience the pattern cylinder or prism 17 may be designated the auX- iliary pattern cylinderor prism and that designated l the main pattern cylinder or prism. Both of the pattern cylinders or prisms serve to actuate the needles 1 2, and thereby control the engagement of the up- IOO rights with the moving griiis, although they are not both operative in this respect at the same time. The auxiliary pattern cylinder' orprism 17 preferably, as in the drawings, cooperates with the needles 1 2 through the medium of a second set of needles, certain of which are shown at 5 6, and which needles may for convenience be designated herein the auxiliary needles,the opposite ends thereof being supported in stands 13 and 14. Springs 121 121 are shown applied to the various needles 1, 2, 5, and 6 in usual manner and operate to press the said needles toward the respective pattern cylinders Aor prisms. The auxiliary needles 5 and 6 are connected operatively in suitable manner with the needles 1 and 2 for the purpose of enabling the said needles 1 and 2 to be operated when desired by or through the said needles 5 and 6. 1n some cases the mode of connection may be varied from that herein illustrated. In the present case the needles 1 and 2 are shown connected with the needles 5 and 6 by means of levers in the form of wires 3 and 4, which last, respectively, at or near their opposite extremities pass through eyes in the needles 1, 2, 5, and 6, each lever or wire 3 at its upper extremity passing through an eye of a needle of the auxiliary set 5 6 and at its lower extremity passing through an eye of a needle ol' the main set 1 2. At intermediate points in their length the levers or wires 3 f1 take bearing against transversely-extending rods 20, the latter constituting fulcra for the said levers or wires when they are moved in consequence of endwise movement of the auxiliary needles 5 and 6. The rods 20 are arranged in an inclined series in supports 2l, as shown clearly in Fig. 2, in order that each lever or wire 3 f1 may have its fulcrum-rod 20 located substantially equidistant between the auxiliary needle and main needle with which it coacts. Enlargements or heads 73 73 on the wires or needles and et support the latter vertically by resting on the upper sides of the eyes of the auxiliary needles 5 and 6. It will be obvious that when one ot' the auxiliary needles 5 6 is moved endwise through the pressure of a blank or unperforated portion of a pattern-card on the auxiliary pattern cylinder or prism 17 the corresponding needle oi the main series 1 2 will be moved endwise through the action of the intermediate wire or lever of the series 3 ein precisely the same manner as if such needle of the main series were pressed back by a blank or unperforated part of a pattern-card on the main pattern cylinder or prism 1 6. Thus the main needles 1 2 and the hooks or uprights 71 71 in engagement therewith may be borne to the left in the drawings through the action of pattern-cards `on either pattern cylinder or prism. 8o far, therefore, as the matter of determining the engagement of the uprights 71 71 With the moving griff-blades is concerned it is immaterial which of the pattcrncylinders or prisms is brought into action.

The pattern cylinders or prisms 1G and 17 are mounted, respectively, in carriers or battens 26 27. (See Fig. 1.) The said carriers or battens may be of any approved construction and arrangement. The inode of mounting the same may be varied. Herein the carrier or batten 26 is provided with rods 28, that are iitted to guides 281 281 on the framework 25 of the jacquard-machine, the said rods 28 being arranged to slide horizontally through the said guides. In like manner the carrier or hatten 27 is provided with slide-rods 29, that are fitted to guides 291 on the framing With the carriers or battens 26 27 I com bine suitable mechanism for operating the same, such mechanism including clutch devices or clutches by means of which the rcspective carriers or battens may be connected with the said mechanism and disconnected therefrom. The preferred mechanism consists ot` reciprocating arms or bars 32 33, hereinafter terme( actuators,since theirfunction is to become connected with the carriers or battens and to operate the same. Any suitable arrangement for reciprocating the said actuators simultaneously with each other, but in opposite directions,may be adopted in practice; but I havesho'wn the inner ends of the same connected pivotally with a rocker-arm or rocker 30 at opposite sides of the pivoted stud 48, by means of which the said rocker is mounted on the framing 25 of the jacquardmachine. The said rocker 30 is intended to be operated in practice by any of the means usually employed for actuating the like parts in jacquard-machines. The outer ends of the said actuators are supported by means of pins 361 371, projecting from collars 36 37, respectively, made fast on the slide-rods 28 29, the said outerends being `l'ormed with longitudinally-extending slots 321 331, which receive the said pins. During the outward movement of an actuator the shoulder at the inner end of its slot 321 or 331 in case it encounters the pin 361 or 371 acts against the said pin to force the corresponding carrier outward into the position that is occupied by the lefthand carrier in Fig. 1, the carrier remaining in this, its idle position, so long as it remains unclutched from its actuator. During the time while one of the carriers remains in the said idle position the other carrier remains clutched to its actuator and moves therewith. The clutch that is employed in connection with each carrier consists, in the present embodiment of the invention, of a simple hook or latch 34 or 35, which is pivoted to'the actuator, as at 34.1 or 351, adjacent to the slot in the latter. The engagement of the said hook or latch with the pin 361 or 371 is intended to occur when the actuator has reached the outward extreme of its movement, the inner end of the corresponding slot 321 or 331 being then closely adjacent to the said pin, and thereby the said pin is held closely between the said hook or latch and the said inner end of the slot, which causes thc carrier IOO IIO

or hatten tobe moved out and in in unison with the actuator. For the purpose of effecting the engagement and disengagement of the hooks or latches 34 35 with the pins 361 371 and controlling the same so asY to occasion the operation of the two carriers or battens alternately I employ in the present instance a controlling-lever 31, which is shown pivoted upon the stud 48, one arm of the said lever extending under a pin 342, projecting from the hook or latch 34, and the other arm thereof extending under a pin 352, projecting from the hook or latch 35. In one position of the said controlling-lever it holds hook or latch 35 raised out of engagement with pin 371 and permits hook orlatch 34 to remain in engage# ment with pin 361. (See Fig. 1.) The pins 342 352 slide along the plain upper surfaces of the arms of the controlling-lever. In the other position of the controlling-leverit holds the hook or latch 34 raised out of engagement with pin 361 and allows hook or latch 35 to become and remain engaged With pin 371.

In accordance with the present invention I provide automatic clutch-operating devices whereby to connect the two carriers for the pattern cylinders or prisms alternately at the required intervals with the actuating mechanism therefor. Thus in the present embodiment of the invention the controlling-lever 31 is connected by means of a wire 311, with an arm or lever 39, which is pivoted upon the stud or pin 49, mounted on the framing 25 of the jacquard-machine. With the arm or lever 39 is connected one end of a cord or the like, as 391, which extends around sheaves or pulleys, as 1392 1392, and has the other end thereof connected to one of the nprights 71. When the said upright is caused to become engaged with the rising griff and is raised thereby, movement is transmitted through the cord 391 to the arm or lever 39, moving it in one direction, the controlling-lever 31 being correspondingly actuated from arm or lever 39 through the Wire 311. Thereby the said controlling-lever is shifted in position, so as to permit one of the clutches-say 35--to engage with the pin, as 371, of the corresponding carrier or hatten, as 27, whereby the latter is brought into action, the other clutch being disengaged from the pin of the other carrier or hatten and the latter being permitted to become idle for the time being. For the purpose of causing the controlling-lever 31 to gravitate to its former position when such return is permitted to take place either the lower arm of such lever is made Weightierthan the other arm thereof in obvious manner or a spring, as 481, Fig. 4, is combined with the controlling-lever, the said sprin g being shown herein mounted upon the stud or pin 48, with one end thereof connected to lever 31 and the other end thereof connected to collar 47, fast on stud 48.

40 designates a locking Varm or lever by means of which the arm or lever 39 is held in either of its extreme positions until a shift thereof is required to be made. The said locking-lever 40 is pivoted upon pin orstud 50, projecting from framing 25, and has a toe 401 engaging with two teeth 392 392 upon the arm or lever The said toe 401 of the locking arm or lever 40 engages alternately with the respective teeth 392 392 of arm orlever 39 to hold the latter in its said extreme positions, respectively.

To carry the lockingarm orlever 40 toward arm or lever 39, a spring 402, Fig. 5, is combined with the former, the said spring being mounted on stud or pin 50 and having one end thereof connected with the locking arm or lever and the other connected with the framing 25. For the purpose lof operating the locking arm or lever 40 automatically Whenever it is desired to disengage the same from the arm or lever 39 and permit the position of the latter and of the controlling-lever 31 to be altered the said locking arm or lever 40 has ,connected therewith a cord 403, extending around sheaves or pulleys 404 404 and also connected with one of the uprights 71, as shown.

The usual actnating-pawls for the main pattern cylinder or prism 16 are shown at 43 44, the same being connected by rod 45, as usual, While the actuating-pawls for the auxiliary pattern cylinder or prism 17 are shown at 41 42, their connecting-rod being designated 4G.
