l?) UU /r/'lf/m it muy concern: i

le it lmoanthat l, .l'osnrii A. (lucenti, ay citizen ot' the United States, and airesident ot' the city` county. and State ot' lNeiv York, hare invented a certain new and useful Jac,- quard, of which the following a speciiication. I, f

lily vintention relates to a jacquard or automat and it has indre dir-ect reference to a jacquard for operating` the tambomvframe of an embroidering machine.

In embroideringy machines of the large type in which the fabric is stretched upon a tambour frame before a large number otI needlesI which are moved in and out always in. given paths, it necessary to move the tambour t ame f '-1"each stitchingr operation.

so that the stitches.- Will be, formed on tln` fabric to produce the desired design and the principal, though iiot only, function ot an emln'oidrring machine jacquard. is to more the tambour 'trame a-t'tcr each stitch, so that the desired design will be produced in mul tiple, upon 'the fabricn by the. various ueedles. -`lnasmush the `fabric' or tambour frame must be' moved almost universallywithin the extreme limits of its motion, thejacquard if operated on a unit system` must be capable of moving` the tambour frame many di'lterent units incxtent'iu any direction. i

lln U. S. Patent #528632, dated November G, 1894, l showed in detail-a cmuplete jacquard mechanism foroperatiug cubi-oidering machines, which has'proven veraf successful: and in Vwhich a large number ot' ultimate movei'nents are produced by com bining movementso1c ditlerent units in extent. in vvariouscombinations. ln that pat.- ent l showed how the number of slides could be reduced to a'comparatively small numlt may be here stated- Specicatfon of Letters Patent. ilpplcaton filed July 11, 1911. Serial No. 638.012.

vin its entirety as the foundation of the pres ent invention, except in so far as parts of that structure arey obviously supersededby the mechanism shown in the present drawings In the patent referred to I showed a number of needlesl (3:2) which are operatedupon by the jacquard card when the latter is reciprocated at each operation, and the needlescause the reciprocation of certain T slides. which in turn reciprocate certain selecting slides. These latter cause thc coupling' of various sliding trames which are reciprocated by a levcrwhich produces different units of movement in the several slid.- ing frames, with4 certain rack bars. The combinations caused by the -interlockingot' the diti'erent sliding frames with the (lider1` ent rack frames results in various ultimate movements beingr produced upon the tainbour frame of the embroidering machine. The purpose of the slides is to selectand combine the 'arious unitsI of movement, while the operating force itself, is intro. duced through the lever above referred to which operates the sliding frames. The various devices for selecting` the slifles,'locki1ig them, causing the devices to be interlocked, which are selected; and producing the operating;r force and transmittingr it to the` tambour frame all operate in regular sequence. The time actually consumed during' each completejacquard operation, in the actual moving of the tambour frame therefore is but. a part of the time, consumed in the complete operatiorn from the movement of the jacquard card to the `i'n'ovem'eut of the tambour frame. In order to have the embroid, cring machine operate rapidly ity is necessary to speed up the jacquard, andas the diflerent parts of the jacquard mechanism must operate in a given sequence' it is necessary to operate some parts thereof, very rapidly, in order to allow a sulicient proportion of the time of each operation .for thel move"- ment of the tambour frame. '-,I The vobject of my invention is to provide certain. mechanism in duplicate relation, with means for causingl the duplicate sets to operate alternately to each other. In this way, each separate setof devices may be -operated at a reduced speed over the former corresponding devices, when -the jacquard is operated at-the same speed as heretoforl.

rllie slides 1T, .i -are arranged in loiir groups represent-ing lf none ot no forward `will operate through their respective rods 67,y to move the selectingslides 68, which constitute the second set. rThis may take place before the slides Q9, have been returned from their operation, and before' the plates 37, have been returned to position, because the movement of the slides (i8, forward, in no way adects the plates 87. :When the siides are moved forward, they will be N iocked by their locking bar,"105 in similar manner to the first set of slides. The levers 121 will be moved downwardly, and will be actuated by'the inclines 122, of anyof.

operated on the slidds 17. The lookingbar.

105,A will" also be operated to perform' the same locking action upon the slides'l, that the locking bar r99, did upon the slides 17. When the locking oar 133 is released from theplates 37, following the completion of the first operation, andthe plates 37, are free to move the second set of jaws will come into operation upon the selecting slides 68, and again position the plates 37, for the second operation. Since the slides 68 engage between the pins 75, 76 of the plates 37, they are adapted to have the sam'c action upon the plates as the slides 29. The jaws 89, 90 will now *ne moved toward each otherby the rocking of the shafts 86, 87, when tothe jaw 99,- will engage the cut out 78, of the slides 68, which have been advanced and will have no action thereon, exce t to' retain them in position: While thosewsides which were not moved forward in the-shove operation, will be engaged by the jaw 90, at the part 77 and will be raised oscillating from their'ends 682. The upper jaw 89, coperates i'n keeping the advanced slides from moving. The upward movement of the 5o slides which were raised by the jaw 90, will raisethe plates 37, with which lthey rey spectively engage. The locking har .133,

having been swung out of the slots 135, to permit 'of this movement, the same as in the previous operation and returned therein, to retain the plates 37, in their raised, or low position, as positioned by the selecting slides, so that the slides may be released by the jaws 89, 90, and be returned to their original or normal position. When the jaws 89, 90, in the operation just described were .closed upon the slides 68, the arm 183, moved simultaneously with the shaft 8E, and this caused the link 185 and arm 186, to

rock the shaft 94.' The rod 96, moving and arm 182, will rock shaft 109; andthe derI nsuch conditions are smoother and less' .tambour frame o eratmg mec anism. adaptwith the latter shaft, caused `all thmslide" 17 'which had heen moved forward in 'the first described Ioperation tobe returned to their originel 'or starting vposition. Upon the completion of this second operation,` 'the' *ja main shaft will have been revolved two .complete revolutions while the "shaft 129,

will' have made one* complete revolutionj The'nextfor third. operation of the jaifard will bring' th slides 17, into action, and so 75 on; and the n edles will be rocked rinto line for the. operation of the slides 1'7. This alternitingcperation will go' on -so long as the jacquard is in operation. The slides 68', `61,*3which were moved -forward in the secondoperation described will be returned when the third operation has partially taken place. When the jaws 84, are closed -'in the third operation, the 'arm 180, link 181 movement of the bar 111, will return the slides 61, and 68, to their normal position. The different devices or selecting and combining the units o movement, must vnec,- essarily operate in a given sequence, and ,where one set only is employed their operations must be rapid in order to operate the jacquard at the Adesired speed and allow a sufficient proportidn of the Whole movement for .the actual positioning of the tambour: e frame. By providing a duplicate set of se ledting devices and operating them in lalter-` nate' relation and at least partly concur-4 rently each may he operatedv at relatively half the speed. The jacquard operations untrying. and if desired, the speed of operations of the jacquard as a' whole may be increased over. former practice. By utilizing plural mechanisms with some parts operating through common mechanism the above. results are obtained with the least possible' increase in the number ofparts. lt will be apparent that a jacquard under my present invention wiil be as positive and' 110 accurate in its operations as heretofore.
