JACQUARD M EC HAN ISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 443,235, dated December 23, 1890.

Application filed March 31, 1890. Serial No. 346,045. (No model.)

To all whom, it may concern:

Be it known that we, JOSEPH E. GARLIOK and ALTERJ. GARLIOK, citizens of theUnited States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Jacquard Mechanism for Looms, of which the following is a specification.

This invention relates to Jacquard mechanisms for looms; and it has for its object to construct a device or mechanism of this class whereby the efficiency of the loom shall be increased; by which a saving in power and in wear upon the loom-harness, as well as in the material which is being woven, shall be effected, and which shall be simple in construction and readily applied.

The invention consists, mainly, in the construction and arrangement of two griffs, one of which shall be vertically movable in the usual manner, and the other of which shall have a limited vertical movement, the latter being adapted to support or sustain in an elevated position such hooks as the pattern may require to remain in an elevated position for more than one pick, thereby greatly lessening the strain upon the machinery, the wear upon the operating parts, and the power required to lift the hooks.

The invention further consists in the improved construction, arrangement, and combination of operative parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of our improved Jacquard mechanism. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a vertical transverse sectional view taken on the line a: 00 of Fig. 2. Fig. at is a Vertical sectional view taken on the same plane as Fig. 2, but showing the upper 'griff in a raised position. Fig. 5 is a side elevation. Fig. 6 is a-top plan.

Like numerals of reference indicate like parts in all the figures.

To the frame of the machine, which is designated by 1, and which may be of any suitable construct-ion, is j ournaled a rock-shaft 2, provided at one end with a lever 3,by means of which it may be manipulated. The ends of the rock-shaft 2 are provided with arms 4 and 5, arranged on opposite sides of the frame,

each of said arms being provided with a camshaped slot 6, and the arm 4 is additionally provided with a sector-shaped rack '7, that engages a spur-wheel or pinion 8,'secured upon a rock-shaft 9, journaled transversely in the frame.

11 11 designate cranks which are secured to the ends of the rock-shaft 9. The said cranks are connected by means of links 12 with the hinged frame 13, in the upper end of which the pattern-cylinder or prism 14 is jour naled in the usual manner. One end of said pattern-cylinder is provided with a star-wheel 15, having a number of points equal to the number of sides of the prism, usually four, and engaged by a hook or pawl 16, which is secured pivotally to the frame of the machine.

The sides of the frame 1 are provided with bearings for the vertically-sliding rods 17, to the upper ends of which the griff-frame 18 is secured by means of set-screws orin any convenient manner. Said griff-frame is provided in the usual manner with theinclined knives or blades 19, and it is provided with the upwardly-extending parallel flanges 20, having slots 21, that form guides for the lugs or studs 22, extending laterally from the grate-frame 23, which is provided with a number of transverse grate-bars 24 equal to the number of knives, in the rear of which they may be arranged. The lugs 22 at the front end of the frame are provided with friction-rollers 25, working in the rearwardly-inclined slots 26 in brackets 27, which are secured to the sides of the main frame of the machine. It willbe seen that, owing to this construction, when the griff is raised the grate-frame will be moved in a rearward direction until the gratebars will almost come into contact with the knives or blades of the griif.

The grifl -frame 18 is provided 011 one side with a loop or staple 28, which encircles an arm 29, that extends upwardly from the pivoted hook or pawl 16. As the griff-frame is raised the hinged frame carrying the patterncylinder is thrown outward and the hook 16 engages the star-wheel of the pattern-cylin der, which is thereby partially rotated, so as to present a new card to the needle mechanism. lVhen the griff-frame has been raised, the staple 28 will engage the arm 29 and hold the hook or pawl 16 out of engagement with IOC the star-wheel, so that the second outward movement of the pattern cylinder taking place during the lowering of the gril'f-frame shall have no effect upon the position of the pattern-cylinder.

The operation of raising and lowering the grill-frame is performed by means of the lever 3, attached to the rock-shaft 2, the arms t and 5 of which are provided, as described, with cam-shaped slots (3. The said slots engage rollers 30 upon the ends of cranks 31, that are pivoted to the sides of the frame, and said cranks are in turn connected by pitmen 32 with the lower ends of the rods 17, to the upper ends of which the griit-frame is secured. It will be seen that by manipulating the rock-shaft the slotted arms 5 and 6 will engage the rollers 30 upon the cranks 31 so as to swing the latter upon their pivots, thereby raising or lowering the supporting-rods 17 according to the direction of: the movement. lly the same operation of the rock-shaft the segmental rack 7 will engage the pinion 8 upon the rock-shaft 9. The arms or cranks 11. of the latter are connected, as above described, by the links 12 with the hinged frame 13, carrying the pattern-cylinder, and the parts are so proportioned that on the upward move ment of the grill-frame 18 the said frame 13 shall be swung outward and back, which movement of frame 13 is repeated on the downward movement of the gritfframe. \Vhen the griI't-frame moves upward and while frame .13 swings outward, the starwheel of the pattern -eylinder is engaged by the pawl 10, and said cylinder is partially rotated, so that a new patterircard shall ongage the needle mechanism when the griffframe 18 is at the upper limit of its movement. At this time, however, the pawl 16 is raised and held out of engagement with the star-wheel, so that when the frame 13 is vibrated on the downward movement of the gritf-frame the position of the pattern-cylinder shall not be changed. Hence it will be seen that each pattern-card is presented to the needle mechanism twice in succession, first when the grill-frame 18 is at the upper limit of its movement and again when it doscends.

Suitably mounted to slide vertically in the main frame 1 of the machine is the supplementary griff-frame 33, having transverse inelined knives 31. The gril't-frame is provided at its four corners with downwardlyextending lugs 3-3, to which are pivoted arms or links 36, the lower ends of which are in turn connected pivotally with links or levers 37, which are mounted pivot-ally upon the upright sides of the main frame 1. The knucklejoints thus formed are connected by longitudinal connecting-rods 38, so as to work in unison with each other. The links or levers 37 at the front of the machine are provided with projections 39, having cam -shaped grooves l0. The rock-shaft 2 is provided with downwardly-extending arms 41, the lower ends of which are provided with laterally-extending pins carrying frictionpulleys 42, adapted to engage the cam-grooves it) for the purpose of manipulating the knuckle-joints supporting the grift-frame 3 as will be presently described.

all designate the longitudinallysliding needles, which are mounted in suitable bearings in the frame 1, and which are so disposed as to be in alignment with the perforations of the pattern-cylilnler. Springs 44: are arranged to force the needles automatically in a rearward direction and into such of the perforations in the pattern-cylinder as are not covered by the pattern-card. The needles ll are provided in the usual manner with loops -15, through which extend the vertically-arranged hooks to, which may be construeted of wire bent so as to form the hookpoints l? at their upper ends, and having their lower ends provided with upwardly-extending arms l8, which likewise terminatein the hooked points it). Each of the so-called hooks therefore virtually comprises a vertically-arranged body extending through the loop 15 in one of the needles and having two independent hooks 47 and t9. The lower ends of the hook-bodies to are connected with guide-wires on, extending through a perforated guide-plate 51, and the lower ends of which are in turn connected in the usual manner with the harness of the warp-threads.

52 designates a grate-frame, which is suspended from the rock- shafts 2 and 9 in the frame 1 by means of links 53, and the bars of which simply serve to separate the verticallymovable hook-bodies 46. At the normal or initial position of the mechanism the grittframe 18 rests in a lowered position upon the upper end of the frame 1,and the lower griffframe occupies a raised position. All of the hooks are at. this time lowered, and the hooks 17 are in position to engage the upper edges of the inclined knives 19, while the hooks it) are some distance below the knives 3-1- in the grid-frame At this time the springs ll press the needles ll in a rearward direction, and such of said needles as are in alignment with the uncovered perforations in the pattern-cylinder enter said perforations, and the hooks controlled by said needles will consequently be in engagement with the grilt-blades l9. \Vhen the rock-shaft 2 is oscillated by depressing the lever 3, the grit't-tra me 18 will be moved in an upward direction, and the hinged frame 13, carrying the pattern-cylinder, will be at the same time swung in .an outward direction, causing the pattern-cylinder, by the engagement of the star-wheel 15 with the hook or pawl 1.6, to be partially rotated and the next pattern-card to be presented to the needle mechanism. As

the griff-frame 18 moves upwardly, the gratetrame will be moved in a rearward direction by the action of the guide-pulleys 25 engaging the rcarwardlydnclined slots 26 in the brackets 27, and this rearward movement of the grate frame will continue" until the grate-bars 24 press such of the hooks 47 as are in engagement with the knives 19 into close contact with the edges of said knives, thereby preventing any of the hooks from being accidentally dropped. The upward movement of the griif-frame 18 of course ceases when the crank-arms 31 have assumed an approximately vertical position; but the length of the cam-slots 6 is such as to permit the oscillation of the rock-shaft 2 to be continued until the rollers 42 upon the arms 41 of said rock-shaft engage the cam-grooves 40 upon the links or levers 37, which form a part of the kn uckle-j oints supporting the lower griifframe 33. The latter will thus be lowered to a position in which the hooks 49 may engage the knives 34. At this time the pattern-cylinder is in position to engage the needles 44, and consequently the hooks 49, controlled by such of the needles 44 as are in alignment with the open spaces in the pattern-card, will engage the knives 34 and remain supported upon the latter, when by a reverse movement of the rock-shaft 2 the grid-frames are restored to their respective normal positions preparatory to a repetition of the operation, and the pattern-card is a second time presented to the needle mechanism. It is obvious that such of the hooks as should be up foranumber of picks will be maintained in an elevated position as long as the needles controlling said hooks register with the perforations in each succeeding pattern card. \Vhen the needles are pushed forward by a pattern card, the hooks controlled thereby are thrown off the knives of the lower grift and caused to descend. On the downward movement of the upper griffframe the grate-frame 23 is moved forwardly and restored to normal position by the friction-rollers 25 engaging the slots 26. The hooks 49, controlled by such of the needles 44 as are not in alignment with the open spaces in the pattern-card, will be out of engagement with the knives and will be lowered with the griff. I

It will thus be seen that by our improvement such of the hooks as are connected with warp-threads, which it shall be necessary in the production of a certain pattern to raise repeatedly in theformation of the shed, are act ually raised but once and remain supported in an elevated position until the particular warp-threads controlled by such hooks are to be dropped, when the said hooks will be antomatically restored to a lowered position by the needle mechanism, which is controlled in the usual manner by the pattern-card; and inasmuch as by this invention the individual hooks are manipulated much less frequently than heretofore it will be readily seen how a considerable saving in power and in wear upon the parts of the mechanism is eifected.

Having described our invention, what we claim is- 1. In a Jacquard mechanism, the combination, with the vertically-movable gritf-frame,

of the latorally-reciprocating grate -frame and mechanism for forcing the latter in a rearward direction simultaneously with the upward movement of the griff-frame to place the bars of said grate-frame in contact with the upper ends of the hooks, which are thereby retained securely upon the knives of the grid, substantially as set forth.
