17 Claims.

My present invention refers to certain new and useful improvements in means for loading or mounting loops on the feed members of the kind that are employed in automatically delivering the loops of header fabrics or other edgings to a machine which operates to make and apply tufts or balls or other ornamental features to such loops; and the invention consists essentially in means whereby the loops may be loaded or mounted upon the tubular section of the feed member which is described in my copending application led July 30th, 1935, Serial Number' 33,889 for Automatic loop feed for machines for applying ornamentation to header loops.

Said mechanism in my copending application includes devices for causing the loops to be carried in a series of successive individuals into the die mechanism of a machine which forms and attaches ornamentation to the loops, so as to manufacture ball fringe or some similar textile product, and the feed member alluded to which constitutes a part of the automatic loop feed mechanism consists of two parts, one being a slotted and notched delivery end and the other 25 being a tubular rod or member, the two being separable from each other at times and being conjoined rectilineally by frictionally inserting the delivery section into the tubular end of the other section when the device is arranged in a ..0 manner for actual operation. The tubular part of the feed member is taken out of the supporting frame from time to time to be reloaded with a length of looped fabric whoseloops will be strung on the said tubular part. In view of the fact that this reloading or remounting of loops upon the tubular member occurs very often, it becomes necessary to devise some effective means for doing this work promptly and efiiciently and said means constitutes the substance and object of the present invention.

Similar characters of reference designate corresponding parts throughout the different figures of the drawings.

The main parts of the machine in which the tubular feed member is to be temporarily held while the loops are being delivered thereto, and in which the several operative parts are arranged for conjoint actuation in delivering the fabric having the loops into a proper relation to the tubular feed member in order that the loops may be transferred to said member, as also the mechanism for effecting such a transfer and enabling the said feed member to be fully supplied with a series of loops which i'lll it from end to end so that it can be then removed and put into use in its normal relation to the mechanism for which it is intended, are all shown as arranged in a frame consisting in the present example of the invention of vertical end standards, uprights, or posts I, joined together by longitudinal top rails 2 and longitudinal lower rails 8, while suitable crosspieces connect the posts I so that the whole forms a solid framework of convenient size and plan.

On the top rails 2, near one. end of the ma- "chine, is mounted a light upright frame I3, which is held adjustably on the rods 2 by set screws or the like, and which carries at the upper end a clamp shown in detail in Fig. 9, and consisting of a block 32 held to the frame I3 by a set screw 33 and having a pivoted portion 35 which is slotted adjoining a slot in the part 32 to allow the operation of a thumb nut 34 on a screw bolt which is pivoted at 36, the contacting faces of the

members

32 and 35 being bored to receive the end of the tubular feed member 3, and the whole arranged substantially as illustrated in Fig. 9, where it is seen that the thumb nut 34 can be screwed down to hold the

parts

32 and 35 together with the tubular feed rod 3 between them. This pivotal bolt may be loosened and dropped down to the position shown in dotted lines, so that the part 35 may be lifted into the position shown in dotted lines, which releases the feed member 3 and allows it to be taken out. Near the other end of the machine there is a corresponding vertical frame I4 mounted on the upper rods 2, 2, and this frame carries an open socket I5 in its top portion having a threaded pin on the underside which engages into the frame I4 to enable the socket I5 to be adjustably raised and lowered, it being held in any position of adjustment by means of a set screw. Thus are provided two supports I3 and I4 for the tubular feed member 3, and these supports enable said member to be held fast at one end and to lie loosely at its other end, it being evident that it can be quickly and easily removed or replaced accordingly as it maybe full or empty of loops. The tubular member 3 is simply a hollow piece, with a passage therein large enough for the thread or wire 'l to run through.

The loops with which my present invention is concerned and with which the tubular feed member must necessarily be kept supplied in order to be in a position to properly fulfill its function, are those loops as 6, formed on a header fabric, as 5, clearly depicted in Fig. 2 which header is ordinarily made as a narrow fabric, ribbon, or textile edging, in any usual weaving loom or other apparatus for producing similar narrow textiles, and such loops 6 are provided in a series so that balls, tufts, trinkets, tassels, or other ornamentation may be applied thereto, and thus to the fabric, to make a suitable ornamental fringe which is popularly used with upholstery, draperies, hangings, and other furniture or articles.

As these narrow fabrics come from the loom they carry the loops B of greater or less size, and suitably spaced apart, preferably equidistant from each other. For the purpose of the present invention and in order to enable the looped fabric to be passed through the present machine in such a manner that the loops may be mounted upon the tubular feed member, the producing loom or apparatus invests these loops with a continuous thread, cord, wire, or other iilamentary endless body or element, support or carrier 1, which runs loosely through all of the loops of the series, so that the looped fabric when it begins to pass through the present machine is carrying with it as a part of its construction this loose continuous iilamentary element 1. It is shown very clearly in Figs. 1 and 2i, and in dotted lines in Figs. 3 and 6, and its function will hereinafter be fully explained.

This fabric 5 with its loops 6 and carrying its continuous thread 'I on which all the loops are strung is supplied to the machine on large reels, spools or drums, as 30, which are mounted on a horizontal spindle 4I which projects at right angles from an arm 40 attached to the main frame work, as, for example, to one of the longitudinal rails 2. The spool 39 preferably has a grooved pulley fast on one end, around which passes a belt cord 39 fastened to frame 8 at one end, while the other end carries a weight 3l. This cord and weight serve as a brake on the spool 30 to keep it from revolving too rapidly while the fabric is being unwound therefrom. This fabric, as shown in Fig. 1 unwinds from the spool 30 and passes up into the machine through a guide 45 on one of the posts I,

Power is communicated to the mechanical features of my present machine for their joint operation by a small electric motor 22 carried on the frame 8 and having a driven shaft 22 on which is a drive pulley 26, around which passes a belt 2| that passes also around the pulley 20 on a shaft 3l journaled in the standards I, I, on the right hand end of the machine, as indicated in Fig. I. On the same shaft 31 is another small pulley 39 alongside of pulley 20, around which pulley 39 passes a belt I8 which likewise runs over a tight and loose pulley I9 on a shaft 54 journaled in the standards I, I, at the right hand end of the machine near the top thereof, as shown in Figs. l and 6. This tight and loose pulley I9, is controlled by the operator through a foot treadle 21 pivotally supported adjoining the machine frame, and it actuates a vertical rod 46 on the upper end of which is a cam 4l which acts against a pin on a horizontally sliding bar 50 that carries on its outer end a forked belt shifter 44 that engages the belt I8 and transfers it from the tight to the loose pulley or the reverse at the will of the operator. Thus by a simple movement of the treadle 21 the shaft 54 can be started and stopped and the train of mechanism connected with said shaft be set in motion or caused to stop, all in consonance with the requirements of the feeding of the fabric to such a point in the machine that lits loops may reach their destination swiftly and uniformly on the tubular feed member.

At the rear end of the machine, or in the present example, at the left hand end (the use of left and right and top and bottom being simply for convenience in explanation), is a shaft I9 mounted in the frame standards I at each side of the machine, and outside of the frame this shaft I0 is provided with a grooved pulley II around which passes a belt I2, which runs to the other end of the machine and passes around a grooved pulley 28 on the aforesaid shaft 54 alongside of the tight and loose pulley I 9, in order that power may be communicated through these connections from the shaft 54 to the shaft I0. On the top of the frame work at the left hand end of the machine and above the shaft I0 is a bracket 23 carrying a vertical guide 24. On the shaft I0 between the standards I, I, is a drum 9 on which winds the'thread, cord or filament 'l after it leaves the tube 3, that is to say, after the loops have been transferred from the thread 'l on to the tubular element 3, and this thread or cord 'l passes downwardly through the guide 24 and around the drum 9 and winds thereon until the drum is full. The thread or string 'l when wound on the drum 9 becomes so much waste, as there is no further need for its use in this machine or in fact for any use and it is easier to convert it into waste than to unwind it from the drum 9. Therefore the drum 9 is provided with side disks cut with a V-shaped notch 53 deepinto the disks down to the core or drum, and when the drum is entirely filled up to the peripheries of the disks a knife or cutter may be used to cut across the bunch of thread l and into the notches 53 until the hub of the drum at the center is reached, When the bunch of thread will be entirely cut through and can be pushed off the drum. Then by making a few turns of the loose end of the thread 'I around the drum it can be connected again thereto as to allow the winding of the thread on the drum to continue. The thread 1 thus passes away from the tubular member 3, and when the latter has been completely loaded with loops this tubular part 3 is removed manually from the machine. The portion f the thread between the clamp 34 and the guide 24 must be broken by hand, and the connection of this broken end with the other end of the thread 'I in the looped fab-ric will have to be restored after the empty member 3 has been returned to the machine for a new loading. Several of these tubes 3 can be loaded one after another and a supply of loaded tubes kept on hand for use in the other machine as needed.

In the upper portion of the right hand end of the main lframe are journaled two rollers IB and Il, whose shafts are supported in the vertical parts I, I, the shaft of the roller I1 being in line with the shaft 54 already alluded to, which carries pulleys I9 and 28. Roller I'I has thereon a pinion 43 and roller I6 a pinion 48; which pinions mesh with each other so that the revolution of the roller I1, which is the driven roller, actuates the roller I6. The looped fabric 5 after it leaves the guide 45 is caught between the rollers I6 and I1, and by them is directed forward steadily and lsurely and rapidly, (although not too rapidly because of the detaining effect produced on the spool 3|] by the weight 3|, or its equivalent), and thereafter the fabric is fed toward the tubular member 3, now mounted in support I5 and clamp 34, as shown in Fig. 6, where said member is indicated as empty of loops. Before the end of the fabric which has just passed the rollers I6 and I1 can effectively relate its loops to the feed member 3 it is necessary that the end of the supporting thread l at that point, which is associated with the looped fabric, should be conjoined to the loose end of the waste portion of said thread 1 which is at the other end of the machine. In order to effect this I use the implement 29 which is simply a long piece of wire with a small hook at one end which engages a loop tied in the loose end of the thread 'l near the guide 24, then by running the instrument 29 through the tubular member 3 from the opposite end as shown in Figure 3 so that its hooked end may emerge from the left hand end, the thread at that point can be engaged and drawn through the full length of the member 3 until it emerges fromthe right hand end thereof, and then it can be fastened to the end of the thread 'I which is still connected with the loops of the fabric; and if the two parts are tied together there will be a continuous thread or `iilament once again. The tie or loop at the left hand end of the tubular member 3 to be engaged by rod 29 is shown in Fig. 3, as also the connection of the threads, and the tool in tube 3.

It is not sufficient merely to feed the looped fabric on to the tubular member 3 after the thread 1 has been restored into a continuous line, because the loops 6 as the fabric is moved forward by the feed rollers would strike against the peripheral edge of the end of the hollow feed tube, the thread being much smaller than the tube opening and a clogging would ensue, so that it becomes necessary to provide means for lifting the loops 6 individually over and on to the member 3. This is accomplished by the provision of a pointed guider or shuttle, as it may be termed, shown in detail in Fig. 4. 4 denotes this pointed guide which is hollow and cut with slots for a part of its length so that it may be spring like and can be pressed over or into the end of the tube 3 with a tight grip. The open slots therein communicate with a sidegroove in the pointed end 52, which is adaptedrto impale the loops 6 one after the other and permit said loops to ride upon the guide shuttle 4, as seen in Fig. 1, which results in carrying them one by one over and on to the tube 3, along which they ride easily and without obstruction, because the open socket I5 loosely holding the tube 3 at that point, does not offer any obstacle to the passage of the fabric and its loops. In other words, the effect of such a movement is that the tubular member 3 is in reality substituted for the thread or cordrl on whichthe loops have previously been strung, and this is clearly evident from an inspection of what takes place from such movements as seen in Fig. l, where the tube 3 engages and retains the loops I5 thereon while the cord 1 passes away from such loops E at the left and goes into the waste. In this operation it is quite necessary that the operator should manipulate the loops when they are fed upon the feed member, as the delivery and alignment of loops thereto and thereon cannot be entirely made by means of the feed rollers. It is necessary that the operator should by hand keep the fabric between the point where he bunches it up as shown in Fig. 4 and the feed rollers taut the whole length in order that the loops should easily ride up and take their proper place on the tube 3. By continually manipulating these loops `and pressing them forward into a bunched condition in order that the fabric should be taut when the loops arrive at the pointed guide shuttle 4, said loops may be transferred with eX- treme rapidity to the tube 3, and it only takes a short time to fill the entire tube Vfull of bunched up loops from end to end. The operation is easy and most effective, though it is somewhat puzzling to understand the transfer of the loops andthe elimination of the filamentary support l, which accompanies the loops as an importantY factor until they reach the tubular feed member. Inthus controlling the movement of the fabric and loops the foot treadle is of great value in stopping and starting thefeed.

After the two ends of the string 4 have been tied together near the feed rollers, as is indicated in dotted lines in Fig. 6, said thread 1 will be caused to enter the grooved pointed portion 52 of the guide 4, said guide having been attached to tube 4, and then through the slotted part 5I, and as it is already in the tube 3, it will be noted that it slips easily through the slot in the guiding end 52. The waste drum 3 is posiz tively actuated, as has been pointed out, by

thebelted connection with the drive pulley 28,

which is on the drive shaft 54, so that there isa pull on said cord 'I all the time that the feed rollers IE and I1 are in action, the pulley 9 revolving uniformly with the feeding impulse of the fabric, so that as the fabric advances toward the pointed guide 4 the cord 'I is being pulled through said guide. Obviously when the feed tube 3 has been iilled and it is desired to remove it from. the machine, the pointed guide 4 may be detached from the end of the tube, because it is not needed on the feed member 3 during the later use of said member in its relation to the automatic mechanism required with the ball fringe machine hereinabove alluded to as being the mechanism with which this tubular feed member s designed to be used.

Of course at all times the starting and stopping 'of the feed is under the control of the operator by means of the foot treadle 21 and intervening mechanism, and this controls the anwinding of the looped fabric from the supply bobbin 30 as also the Winding up of the Waste thread I on the drum 9. The operator can instantly start up and immediately check the movement to correspond with the necessities of the case and the proper delivery and functioning of the tubular member 3 and its reception of the numerous loops furnished by the traveling fabric, and the traveling lamentary element 'l which operates lengthwise through the tubular feed. member and cooperates in the delivery of an endless succession of rings or loops upon the feed member.

I have hereinabove alluded to the fact that the unwinding of the spool or bobbin 30 is delayed or checked by having a pulley and cord carrying a weight hung thereon. The same effect may be produced in a great many other different ways and I do not wish to be restricted to this particular weight effect. Another method, for example, consists of a heavy block 42 pivoted at 43 held normally in a horizontal position in the frame by means of a pin or detent, but if desired it can be released and caused to drop upon the fabric on the spool 3D and rest thereon as a weight, which willl have a braking effect upon the revolution of the spool and cause unwinding to proceed only as fast as may be desired and in a manner that will keep the fabric taut between the spool 3D and the feed rollers.

Various changes in many of the parts and in their relation to each other may be made without exceeding the scope of the invention. It is realized that what is here exhibited is only one specimen of means in which the principles of my present improvements may be embodied, and I therefore reserve the liberty of rearranging and modifying the construction and relative placing of the different members in order to secure the best cooperative results, or to modify the effects in accordance with the needs of individual cases, in order to obtain the greatest breadth of application for the invention and its utmost serviceableness in all the situations to which it is adapted, provided only that such changes and rearrangements are made Within the scope of the appended claims.
