"A TE Lemme ANTHONY e: 12 nussn v, or nneewoon, nnonn isijaixinl 'rnnnan-oonrnon A'r'TAciiMENr For; noolvisi for performing the functions of the jacquard cards and similar devices now generally em-' ployed with looms for weaving designsin the cloth, lace, rugs, and so forth.
It is a further object of, the invention to provide a device for this purpose which will be simpler in construction, cheaper to produce and operate, and which will reliable in operation. Y v 1 a It is a further ,object of the invention to provide a control device for the threads in this type of mechanism which will beeasier and cheaper to make'than the acquard cards,
which will require less space and so may be more easily and cheaply stored when not in 2 use,
iii)
,lVith the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawings, in
which: r i

Fig. 2 is a detailed endelcvation of the device on an enlarged scale.

Fig. Sis a partial plan and partial sec-.-
tional view showing, aslightly diflernt con-.
struetion of strip wherev instead of perforations.
Asis well known, in the usual methods of weaving patterns or designs a series of relatively stiff cards are provided, each card being perforated according to a desired design to'coact with the needle headof the loom to control the threads. Thesecards are laced together by a suitable lacing extending through openings adjacent the opposite'ends of the card, and each card is provided with Application filed June 5,
be more i of the separate cards laced togetherv a cone is a rear view of a portion of the the structure projections are used 192s. e ermine. 643,488.
a relatively large opening at each end to receive positioning pins on the fiat side of a square perforated drum which is used to ad- Vance the cards. past the needle head'by a step 7 by step movement, and also to advance the card against the ends of'the needles in the thread controlling operation, These cards, however, are heavy and cumbersome, are expensive tomake, and the operation oflacing: the cards is also an expensive one; V, The cards are heavyand require a large storage space.
To overcome these objectionsliuse'in place tinuousstrip of flexible sheet material'such aspaper, thin metal or some suitable fabricated substance. This continuous strip may also, be used in place of the" wooden, bars with pegs or'projected sheets used'with' certain types ofrtextile machinery, that is, de vices using a. series ofbars connected by.
chains having pegs that do tripping of.
needles, but intliese cases,h0wever, instead of perforating; the control strip I propose to use in'placc of'theperforationsraised bumps or projections-as shown in Fig.8. *In this case, howeven'the sheet would to be made-of thin metal. Referring-to the drawings, I'haveshownf at 11 a series of harness threadsconnecting the hooks l2 withthe mechanism for lifting probably have the'warp. threads, and the griff bar'13v for raising the hooks whichiarenot moved out. of alignment therewith by, the needles 14 of.
the needle heads, the griff bars being raised by any suitable mechanism as levers 15." As is'well known each needle 14'controls a hook. 12, and the needles are arranged: in a number. of horizontal rows, the number of rows and the number of needles in a row depending onthe design to be woven and the" width of the repeat ininches.
.In using my continuousyflexible stripsof sheet material for .controlling the needles, I preferto'employ a rounddruin in place or the usual square dru'ni usedhwith thejac' quard cards,althoi 1gh I'may, if desired, employ my continuous strip'witlr the square drum; When I employ the round d'runrI remove thesquare drum from the machine and substitute my round drum; the support therefor. and feedingwmechanism-in' place of the square drum, and Ihavejshown on the drawings an improved type of mechanism for using this continuous strip. I
The supporting bars 16 are mounted to no I reciprocate in suitable bcarnage17 onthe frame18 of the 100111 and carrry the usual square drum for use with the laced cards.
, These bars are reciprocated by suitable with mechanism for rotating the drum to.
1 -bars 16 to which the carriage is securely connected. The carriage includes an upright mechanism as a lever 19 connected to them by suitable links 20, and reciprocation of these bars press the cards against the needles and on the backward movement cooperate advance. the next card for the next operation. I mount my improved attachment on these bars in place of the square drum. 7
This devicecomprises a carriage 21 provided with bearing lugs 22 to receive the backing plate 23 for the continuous strip of flexible material shown in dotted lines 24, this backing plate being provided with a series of horizontal rows of perforations 25, onefor each of the needles 14 in the needle head, and at the opposite ends of 'this backing 7 plate areguides 26 for the strip to hold it properly against the face plate. The'carrla-ge 18 provided with bearings 27, 28 for the shaft 29 for carrying the drum or drums 30. In the drawing I have shown two relatively narrow drums, one for each end of the conperforations in the strip successively into cooperation withthe needles. g S The drums 30 are secured to the shaft 29 so as to rotate therewith and also secured to this shaft is a cam or ratchet disc 33provided on its periphery with a series of shoulders or teeth 34 adapted to be engaged by a pawl 35 pivoted at 36 to one arm 37 of'a bell ClELIlK lever fulcrumed on the shaft '29, the pawl being normally held in engages ment with the periphery of the cam or ratchet disc 33 by aspring 38. The other arm 39 0f the bell crank lever is provided with a slot 40'throughwhich extends a pin 41- carriedv by a' pivot lever 42.: The lever 42' is fulcrumed on Ja pivot pin 43 secured in the frame 18 ofpthe loom, and Esecured on this pivot pin is a pivot micrometer 44 having spaced arms 45 in which are'threaded adjusting screws 46 engagingat their ends on opposite sides of a lug 47 carried by the v lever 42.
Thecam or ratchet disc 33 is also provided I on its periphery with a pluralityv of flats 48 corresponding in number to the number of shoulders or teeth "34 and coacting with these flats is a locking plate 49 held against the flats by a spring 50. The coaction of the plate 49 and its spring with these flats locks the drums in desired positions to hold them and the continuous strip 24 stationary and in proper position when thestrip is advancedtoward" the needles.
The operation of this device is as follows: The device is shown in the position spaced away from the levers with the drum and paper locked in position for cooperation with the needles. The carriage with the drum and continuous strip is now advanced toward the needle head, by reciprocation of the bars 16, pressing the strip 24 against the ends of the needles, but the ends of the needles which are in alignment with perforations. in the strip passing through these perforations without being alfected by the strip. The strip during this'operation is held perfectly flat and backed up by the backing plate 23. During this movement to the right, as viewed in Fig. 2, to the dotted line position, as shown, the bell cranklever is rocked counter-clockwise on its pivot to the position shown in dotted lines which brings the pawl 35 in advance of the next shoulder or tooth 34 on the: cam or ratchet disc 33 through the coaction of the pin 41 and slot 40. Vhen the carriage is returned to its original position, as shown in full lines, coaction of this pin and slot will rotate the bell crank lever clockwise, as viewed in Fig.
2, and the pawl 35 will engage a shoulder of tooth 34 and advance the cam or ratchet plate a quarter revolution and with it the drum 30.- During this operation the locking plate 49 will yield allowing the next flat SI ll 48 to be brought into engagement therewith so that the drum and with it the continuous strip of paper will be properly held in the next position. Thus it will be seen that the continuous strip is given a' step by step feeding movement past the needles and each feeding movement is that required to bring the successivesets of perforations in the strip on the face ofthe backing plate 23 and in alignment with the needle head. In Figs. 6 and 7 I have indicated at 51 one set of these perforations, the number of rows, however, being different from that shown in 32 as it will be understood. the
numberof rows of perforations will depend on the size of the design and the number of threads controlled. adjusting the effect of lever 42 on the bell crank during this reciprocating movement,
the postion of the pin 41 carried by this lever may be changed and secured in adjusted positionby the screws 46. i 1 In rug weaving there must be a definite start and finish dueto the border, and therefore, in weaving rugs there must be sufficient of this perforated strip of paper, or other suitable substance, to cover the entire length For the purpose of.
waste of rug, aiid it will; therefbi'e, b en alcon t nuous roll on a drum, and 1f 1t' 1s to be used with a; round dr'umlas shown, it will be apparent 'from Fig. 6 that no space is requiredbetween the successive sets of perforations 51 as is the case where lacing of the cards is required and therefore, the length of strip required for a given pattern with my continuous strip of' flexible material is; less than that required with a series of laced cards. As thiscontinuous strip is not required to be as thick and heavyit will be apparent that there willbe a great saving in the use, of material'and also in the amount of storage space required, to say nothing of the much greater ease in handling. The perforations shown at 75 are so called liftiperforations and are used to control the lift of boxes with shuttles carrying different colored thread. 1
II In' w eaving continuous cloth, however, the design is woven over and over, and therefore, I may use an endless strip of this flexible material, as paper or other desirable material, an d use this endless continuous strip over and over uring the weaving oped therein.
eration, a strip being" of a length required for a single pattern or design. To facilitate the applicationlof this endless stripito' the machine and to allow insertion thereof in position without disconnecting it at. any point, I mount one of the bearings 28'for the shaft29 so that it may be moved to one side longitudinally of the shaft to allow the endless perforatedstrip to ,be placed on the drums. This construction is shown more clearly in Figs.'4c and 5m which the bearing 28 is carried by a bracket 52 mounted to slide on suitable guides 53 carriedby the carriage, the bracket. being provided with suitable guideways for receiving the guides, and the bracket s securedin posit on by suitable clamping means such as a pin 54L threaded in the bracket and operated by means of a lever 55 to clamp a plug 56 against one of the guides 53. A guide plug 57 is also carried by the bracketyhaving a rounded end 58 adapted to enter an opening, in the carrier to properly center the bearing. 28. When it is, desired to remove an endless strip from the drum 01' apply one thereto, all that is required is; to loosen clamp 54, slide the bracket 52 onthe'guide 5 3" to the left as viewed in Figs. 4. and 5, to, the dotted line position, and then the strip may be removed from. the drum and anothenstrip slid onto the same passing down through the guideway or, slot 59. The bracket 52 and bearing 28 are then returned to the full line position and clamp- My continuous strip of, flexible sheet ma terial may also be employed with the square drums now used with the jacquard cards. For this purpose the sets of perforations 51 5 as shown in Fig fi are spaced t o' corr'e- I spend with the spacing of the jacquard cards, and the continuous strip of paper or other material 24c is creased or scored at 60 transversely between these sets of perforations s em the strip will fold over the edges of the square drum and allow the portion of the strips: between thesefolds orscores to lieflat on the flat sides of the drum.
provided with openings 61 to receive the positioningpin on the square drum. If itis desired to use this scoredor folded strip with the round drum, as disclosed in Figs. 2 and 3, these drums are made somewhat larger in diameter than where the strip is not creajsed, as in Fig. 6, to allow for the required spacing between the sets of The strips'represented by the p'ortions between the folding or scoring are also I perfora'tions,- and the strip 24 is provided I with rows of perforations 32tocoact with material, are much easier and less expen -l sive to manufacture than the separate'jacqu a'rd cards now used. They be punched from a master roll automatically by ma} chineryfand as many copies "as desired punched from one master roll. The. ma-.
chine for doing this will be described' and claimed in a separateapplication.
' Fig. 8 I have shown how a continuous stripflmay be used to take the place of the woodenbars with pegs or projectedsheets mentioned above; thiscase the continu- .ous strip 162 is made of thin sheet metal and instead [of perforations is provided with lateral bumps or projections 63 to coact with the thread control needles.
