MACHINE FOR MAKING LACE TRIMMINGS.

SPECIFICATION forming part of Letters Patent No. 781,387, dated January 31, 1905.

Application filed November '7, 1904. Serial No. 231,660.

To all whom it may concern.-

Be itknown that 1, MAX N. AARON, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Machines for Making Lace Trimmings, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to machines for making lace trimmings, and is an improvement on or addition to the machine set forth and claimed in an application filed by me July 23, 1904, Serial No. 217,774. This prior application sets forth a machine which is adapted to inserta ribbon automatical-lyin the ribbonspace of the fabric in the process of knitting the fabric. acter which the machine of said application is designed to make consists of a heading composed (usually) of three longitudinal threads crossed by a number of transversethreads and a ribbon-space formed between one of these longitudinal threads and another longitudinal thread connected together by transverse pillar-bars. The ribbon or braid is inserted in this space by passing it longitudinally in front of and back of alternate bars. While the machine of my prior application is operative to make a fabric of this kind and 8 insert the ribbon automatically in the process of knitting, no means are disclosed the'reinto form loops in the ribbon at determinate distances along the trimming. It is frequently desirable to sell thelace trimming with the ribbon so looped. To do this is the object-of my present invention, which consists in additions to or modifications of the machine of my the machine with some of the parts removed. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is an enlarged view ofa portion of the mechanism shown in Fig. 3 with the parts in a different position. Fig. 5 is a detail view A typical trimming of the char-' positively toward the point of in elevation of the support for the feed mechanism. Fig. 6 is a section on the line 6 6 of Fig. 2. 'Fig. 7 is a perspective view of the looping-finger. Fig. 8 is a front view of a fabric made on a machine embodying my invention, and Fig. 9 is a section on the line 9 9 of Fig. 8.

I shall not describe with particularity the construction or operation of the machine in its entirety, as the said machine is in its main features a well-known typeof what is known in the art as a rib-lace machine, and the means enabling the ribbon to be automatically inserted in the process ofknitting the fabric are fully ,set forth in my prior application. I shall, however, refer to its main features and shall for a better understanding of the present invention particularly describe the ma chine of my prior application, as well as the novel features that distinguish my present invention therefrom. It will, however, be understood that my invention is not limited in its application to the particular type of machineshown, which is merely a type of machine to which 1 have already applied my in- 'vention' and in connection with which I prefer cl. The ribbon-space is formed by the longitudinal thread g and the threads 6 and f, the latter each being twisted along the thread 9 and also extending transversely back and forth between threads g and 0 and looped on the latter, the threads 0 and f thereby forming double transverse pillar-bars alternating with each other and spanning the space between threads 9 and c. The inner thread 0 of the heading may also be said to constitute the inner thread of the ribbon-space, being, in effect, the dividing-thread between the ribbon-space and heading. The ribbon z is in.

serted in this space, being held in place by extending in front of each bar formed by thread 0 and back of each bar formed by thread f, or, in other words. extending in front of and back of alternate bars. At determined distances along the trimming the ribbon is drawn outwardly beyond the plane of the fabric to form loops y, these loops being shown in Fig. 9 as being formed between alternate crossbars, although they may be formed at any suitable distances apart. After the trimming is placed upon a garment, such as ladies underwear, and the garment put on the ribbon is drawn more or less tightly through the trimming for the purpose of adjusting the garment to the wearer, and the excess length of ribbon so produced may be formed by the wearer into an ornamental bow or tie. The machine embodying my invention is adapted to insert the ribbon and form the loops therein in the process of knitting the trimming.

The fabric referred to is only one of numerous fabrics having interwoven therein a ribbon or braid, and such fabric is to be considered merely as illustrative and as an aid to an understanding of my invention and not as representing the only style of fabric to the manufacture of which my invention is applicable, my invention, in fact, being applicable to the manufacture of any lace or kitted fabric containing a ribbon or braid. In the production of this fabric a series of guide-bars are employed, each of which, except one, carries a series of thread-guides and one of which carries a series of ribbon-guides, all of the bars being adapted to oscillate back and forth and some of the bars being adapted to be given a longitudinal movement and all of the guides cooperating with the usual vertically-reciprocating needle-bars carrying the needles.

h is the rear guide-bar, to which are fastened the plates 1', carrying the guides j, said guides holding in position the longitudinal threads 0 of the heading. These bars are substantially stationary so far as longitudinal movement is concerned. It is the next adjoining guide-bar, to which are fastened plates Z, carrying the guides m, said guides governing the position of the transverse thread 01. These bars are adapted to have a regular longitudinal reciprocating movement, so as to direct the thread d back and forth between the outer and inner threads 0 00f the heading to form the transverse bars thereof. n is the next adjoining guide-bar, to which are fastened the plates 0, carrying the guides 12, said guides governing the position of the thread a and being given an intermittent longitudinal reciprocating movement to form alternate cross-bars spanning the ribbon-space between the inner thread 0 of the heading and the thread 9. q is the next adjoining guide-bar but one, to which are fastened the plates 1', carrying the guides 8, said guides governing the position of the thread f and being given l an intermittent longitudinal reciprocating movement (alternating with the similar movement given to the guides 71) to form alternate cross-bars spanning the ribbon-space between the inner thread 0 of the heading and the thread 7. t is the front and next adjoining guide-bar, to which are fastened the plates 11, carrying the guides '11, said guides holding in position the outer longitudinal thread of the ribbon-space. These bars are substantially stationary so far as longitudinal movement is concerned.

Between the guide-bars a and q is a guidebar w, said guide-bar having secured thereto a bracket or ribbon guide it, having a shouldered or enlarged lower end containing a wide but shallow orifice whose dimensions permit the insertion therein and passage therethrough of the ribbon .2, the specific construction of this ribbon-guide being more fully set forth in my prior application. The guide-bar M has no longitudinal movement.

10 is the usual needle-bar, to which are socured the plates 11, carrying the needles 12. The particular arrangement of the needles with relation to each other and to the guides need not be herein particularly described, as the same is fully set forth in my prior application and an understanding thereof is not necessary to an understanding of my present invention. It is suflicient to say that a set of needles is provided to cooperate with the set of guides described and that a vacant space is provided between needles, which space is located under the ribbon-guide w and is adapted to allow the passage therethrough of the ribbon as it is fed forward in the operation of the machine in the manner hereinafter de scribed.

It will be understood that each guide-imicontains a series of guides extending throughout its length and that the needle-bar contains a corresponding series of needles, so as to permit the simultaneous making of a number of distinct sections of fabric. It will also be understood that only such guides of each guidebar are at any given time in active use as are necessary to guide the threads which its guide-bar is designed to control. It will also be understood that as the several sections of fabric are spaced apart during manufacture a certain number of the needles are idle. it will be understood that there are as many active sets of guides and as many active sets of needles as there are sections of fabric to be simultaneously produced.

20 is a shaft having hearings in the machineframe 60.

21 represents brackets depending from shaft 20.

22 represents supports secured to brackets 21.

23 is a series of guide-bar holders, one for each guide-bar. said holders being slotted at 24 to receive a bolt 25, engaging the support 22, whereby the guide-bar holders are adjusta cross-head 28 is secured to the shaft 2O.

This cross-head is slotted-at 29, and in said slot are a plurality of adjustable bolts 30.

31;represents levers secured at their lower ends to the several guide-bars, respectively, while their slotted upper ends engage, re

spectively, th'e bolts 30. Secured to each le- .Ver 31 is one end of a connecting-link 32, the other end of which is hooked into the orificed end of a bar'33, adjustably secured to one arm of a bell-crank lever 34, pivoted on a bracket on the machine-frame. The other arm of the bell-crank 34 carries a roller 36, engaging a pattern-chain 37, extending around a. pattern-wheel 38 on the shaft 39.

' The shaft 20 is oscillated by the usual means,

(not herein shown,) thereby, imparting the usual oscillatory movement to the guide-bars.

The pattern-shaft 39 is given a step-by-step rotary movement by the usual means, (not herein shown) thereby feeding the several pattern-chains 37 and rocking the bell-cranks 34, and consequently giving the appropriate longitudinal movement to the guide-bars with which said bell-cranks are respectively connected. Such of the hooked levers .32 as are connected to the guide-bars to which no l'ongitudinal movement is to be imparted may be disconnected fromthei r respective bell-cranks, v

or thecorrespon ing bell-cranks and patternchains may be removed or omitted. -While the ribbon-guide bar to is shown supported from the shaft 20 in the same manner as the other guide-bars, it is obvious that the particular way in which it is supported terial. q

ing woven.

By reference thereto the I the ribbonffeeding in front of the transverse bars formed by the thread 0 and back of the transverse bars formed by the thread f, thereby causing the ribbon to .be drawn or fed through the ribbon-space alternately in front of and back of successive transverse bars of the ribbon-space in the course of manufacture of the fabric.

I will now particularly describe the novel features of the machine embodying the in vention forming the subject-matter of my present application. I will first refer to Fig. 4, this figure showing in detail the mechanism which directly acts on the ribbonfor effecting the looping operation.

50 is a slide'on each side of the machine, said slide being adapted to work back and forth. toward and from the needle-bar. 51 is a guide within which the outer end of the slide moves. This guide consists of a' side member, against which the outer end of the slide fits, and an upper and lower member, respectively, partially overlying and underlying the slide. 52 is a guide-plate secured to the guide 51, said plate extending a short distance below the lower surface of the overhanging member of the guide 51 and extending in portion extends somewhat above the remainder of the slide. Thus the slide'is prevented from beingdislodged from its guideway, while full freedom of movement back and forth is permitted. 53 is a slide-bar extending the width ofthe machine and secured at its ends to the slides 50. 54is a forwardly-extending looping-finger (shown in detail in Fig. 7) having a s'lottedrear member 55, secured to the slide-bar 53 by means of a screw 56 in the slide-bar. This looping-finger is of about the width of the ribbon 2.. It has a limited adjustment along the slide-bar 53 by means of said screw and slot, so that it may be adjusted It will be understood that there are as many of these loopingfin'gers as there are sections of trimming be- The slide is provided with a large number of holes in excess of the maxi- I mum number-of looping-fingers that will at any time be used, so that the latter may be adjusted along the slide-barat any desired precise points. The slides, slide-bar, and looping-finger are' normally in the position shown in Figs. 2 and 3namely', the forward end of the looping-finger is a short distance back of the needle-plate 42. 57 is an angle-iron secured to the machine-frame at each side thereof, and 58 is an abutment-plate secured to the angle-irons. This abutment-plate is directly beneath the needle-plate 42, a slightspace being left between the two plates to permit, the

ready passage between them of the loopingfingers 54. As the fabric is being woven it and the guide-bar q-for the thread f insures 7 9 inner end of the overhanging member of the IIK' cured to and beneath the slide 50.

abutment-plate 58. Atpredetermined intervals and by mechanism to be hereinafter described the slides are moved forwardly asufficient distance to cause the looping-fingers to pass between the said plates, as shown in Fig. 4, and between the threads 0 and g of the trimming, engaging the ribbon and pulling it through to form the loop 1 as shown in Fig. 9.

It is evident that provision must be made to compel theloop to be formed by pulling the ribbon from above, as if it were pulled from belowit would result in pulling in and destroying previously-formed loops. To prevent, therefore, any upward movement ofthe ribbon during the operation of the loopingfingers, I have provided the following mechanism for directly acting upon the ribbon for the purpose of holding in position during the formation of a loop the loops previously formed: 66 is a clamping-bar secured at each end to a rod 61,which extends through orifices in the front and rear legs of a bracket 62, se-

63 is a pin or stop on the rod 61. 6 1 is a spring confined between the pin 63 and the rear leg of the bracket 62. The clamping-bar is normallyin the position shown in Fig. 3 namely, the forward end of the clampingbar is a short distance back of the abutment-plate 58 and preferably slightly in front of the front end of the slide-bar 53. As the slide-bar 53 is moved-forwardly. as before described, the clamping-bar 66 is also moved forwardly until it abuts against the trimming-back of the abutment-plate 58. Thereafter during the passage of the looping-fingers between the

plates

58 and 42 the rear leg of the bracket 62 compresses the spring 64, causing the lat ter to press the clamping-bar forwardly with a strength dependent on the tension of the spring, confining the trimming tightly between the clamping-bar and the abutmentplate, and consequently holding the ribbon from movement.

From the foregoing description it will be apparent that the length of ribbon required to form a loop must necessarily be formed by drawing the ribbon downward from its source of supply and that there is no danger of drawing in and destroying a loop that is once formed. It is also advisable, while the looping-lingers are inoperative, to prevent the tension on the trimming exerted by the guidebars in their oscillation back and forth from drawing up the ribbon and partially or wholly drawing in the previously-formed loops. To this end I provide a holding device or friction roller 661, extending across the machine-back of the upper portion of the needle-plate 42, said friction-roller being hung on levers 67, pivoted on brackets 68, secured to the upper end of the needle-plate and nor-- mally by its weight pressing against the trimming, as it is formed, with sufiicient force to prevent the ribbon from being pulled upwardly. The pressure of this friction-roller, however, need not be sullicient to prevent the ribbon being fed forward with the trimming, as the latter is formed by means of the usual take-up roll. It is necessary, however, that this roller should be retracted during the operation of the looping-lingers, as otherwise the action of the latter in pulling down the ribbon would be interfered with by the pressure of the roller. To effect this purpose, I provide the following mechanism: 70 is a shaft extending across the loom and turning at each end in a bearing formed in a bracket 71, which also supports the guide 51 previously described and which is itself supported on a standard '72, secured to the machine-frame. The shaft 70 is intern'iittently operated by mechanism hereinafter described. Secured to the shaft at each side of the machine is a bell-crank lever 73, one arm of which is connected through alink H with the slide 50. The othe arm of each bell-crank extends immediately under the axle of the corresponding friction-roller 661. As the shaft 70 is turned on its axis, so as to move the bell-cranks from the position shown in Figs. 2 and 3 to that shown in Fig. 1-, the slides 50 are moved forwardly to operate the looping-lingers 5 1 and clamping-bar 66, as before described, and at the same time the roller 661 is lifted away from its operative position into the position shown in Fig. 1, thereby pern'iitting the ribbon to freely feed downwardly under the pulling action of the looping-lingers. As the shaft 70 is returned to its normal po sition the slides 50 are retracted, witlulrawing the looping-lingers 5st and clamping-bar 66, and the roller 661 is permitted to again drop into operative position.

In place of employing the friction-roller 661 to prevent the pulling up of the ribbon in the trimming previously formed and looped I may utilize the clamping-bar 66 for the purpose. It will be understood'that in all machines for making lace trinnning a pawl-andratchet mechanism (not shown) is employed to operate a take-up roll, (not shown,) whereby the trinnning after each course of knitting is fed forwardly. During the operation of the take-u p roll the clamp 66 must of course be in its retracted position, as shown in Figs. 2 and 3, so as not to interfere with the intermittent feeding forward of the trimming. Moreover, there is no necessity during the operation of the take-up roll for providing any special means to prevent the ribbon be ing pulled up by the guide-bars, as the stronger downward pull exerted by the take-up roll offectually prevents this. The neeesslty for providing this special means exists, therefore, only while the take-up roll is inactive. It will be understood, therefore, that if the clamping-bar is moved forwardly, so as to press the trimming against the abutmentplate 58 during the time that the take-up roll is inactive, the ribbon will at all times beheld from upward movement. I therefore cause I the slide 50 to move forwardly after each pulled upwardly or the friction-roller 661 may be employed, and the clamping-bar may be thrown into action only during the operav tion of the looping-fingers. or the clampingbar may be thrown into action after each operation of the take-up roll and the frictionroller 661 omitted. I

I shall now describe the mechanism for intermittently turning the shaft 70. I have hereinbefore stated that pattern-chains 37, extending around a pattern-Wheel 38 on the shaft 39, engage rollers 36 on bell crank levers 34 for the purpose of giving the appropriate longitudinal movement to the guidebars with which said bell-cranks are respectively connected. I select one of the bellcrank levers 34 not connected with a guidebar for the purpose of actuating the shaft 70. To the end of the roller-carrying armof such bell-crank is secured an arm 76.

79 is a shaft turning in bearings in the machine-frame.

78 is a lever secured to shaft 79.

77 is a connecting-rod between the outer end of lever 78 and the end of arm 76.

a lug 83 passes under and elevates the end of said bell-crank, the chain of mechanism just described turns the shaft to the extent necessary to move into action the'loopingfingers and the clamping-bar and withdraw from operative position the friction-roller. When the lug 83 passes from under said bellcrank, the latter drops, restoring shaft 70 to its normal position, Withdrawing the loopingfingers and clamping-bar, and permitting the friction-roller to again drop into operative position. When it is desired to bring theclamping-bar into operation after each action of the take-up roll, as well as during the operation of the looping-fingers, 1 provide the patternchain with low lugs 107, .as well as high lugs 83. When a low lug is moved under said bell.- crank, the chain ofmechanism leading to the slide 50 is operated and the slide is moved forward sufficie'ntly far to move the clampingthrough a recess 102 in bracket 85. v ribbon-guide roller secured to shaft 97 bar into action, but not sufliciently far tocause the looping-fingers to operate. I

It is desirable to provide positive means for feeding the ribbon from its spool or beam as fast as is necessary to supply the length required in the trimming as it is made and in the loops as they are formed, thereby delivering the ribbon freelywithout subjecting it to tension. To this end the following mechanism is provided: 85 is a bracket (shown separ-' ately in Fig. 5) secured to the beam-stand 4:6. This bracket is provided with a T-slot 86, containing a nut 87, (see Fig. 6,) which fits therein neatly, so as to be incapable of turning therein. 88 is a bolt having a reduced end 89 adapted to engage the nut. Loose on the bolt 88 is a ratchet-wheel 90, the hub of which is provided with a key 91. 92 is a gear-Wheel having akeyway. By means of this key and keyway-the gear 92 is secured to the ratchetr wheel 90, so as to turn therewith. 93 is a lever pivoted between its ends on bolt 88. By screwing up the bolt 88 the nut is drawn to ward the outer wall of the slot 86, and the shoulder formed at the beginning of the reduced portion of bolt 88engages the outer face of the bracket 85, thereby securely fastening the ratchet 90, gear 92, and lever 93 in position. 94 9t are pawls pivoted to lever 93' on each side of the ratchet and adapted to turn the ratchet at each reciprocation of lever 93.. -The lever 93 is operated by connecting one end thereof with the lever 106 on the shaft 79 by means of the link 95.

96 is a shaft extending across the machine and turning in bearings in the beam-stand.

The shaft 96 also extends through an orifice 101 in the bracket 85. is a gear-Wheelsecured to shaft 96 and meshing with the gear 92. 97 is a ribbon-guide roller secured to shaft 96. 98 is another shaft extending across'the machine and turning in bearings in the beam-stand. The shaft 98 extends 99 is a 103- 103 are brackets secured to the beam-stand, and 10 1 a shaft extending across the machine and supported in said brackets. 105 repre sents ribbon-spools arranged along said shaft.

-Each ribbon extends from its spool 105 to and partly around roller 99, thence between

rollers

99 and 97, thence'partly around roller 97,-and'thence down to the guides and needles. As a lug on the pattern-chain passes under and elevates the end of the bell-crank confined between

rollers

97 and 99 are thereby fed ofl their spools 105. It will be understood that the ribbon is fed from its spool or beam each time the bell-crank is under-ridden by a lug whether high or low. When the mechanism is actuated by a low lug, the ratchet will be turned, say, only one tooth, Whereas when the mechanism is actuated by a high lug the ratchet will be turned a plurality of teeth. Thus the ribbon will be fed from its spool or beam during the operation of the looping-fingers and also during the normal knitting operation. The length of ribbon fed from the spools at each operation of the actuating mechanism may be regulated in different ways. For example, gears of different sizes may be substituted for the

gears

92 and 100 to turn the latter a greater or less distance on its axis, and thus increase or decrease the feed, or the link 95 may be adjusted at diflerent positions along the lever 93.
