REED-WEAVING MACHINE.

Application filed May 28,,

To all whom it may concern:

Be it known that I, MARsHALL B. LLOYD, a citizen of the United States, and resident of Menominee, county f Menominee, and State of liiichigan, have invented a certain new, useful, and Improved Reed- Weaving Machine, of which the following is a specification.

.My invention relates generally to improvements in machines for weaving fabric of which reed is characteristic, and which is composed of a plurality of spaced members called stakes, upon which long strands called fillers are woven, over some of the stakes and under others.

The object of applicants invention is to produce a machine wherewith reed fabric can be produced mechanically. Another object of applicants invention is to produce a reed weaving machine which shall be simple-in construction; which shall require but little space; which shall produce in a given time, many times the amount of fabric now producible by hand; which shall produce a fabric of greater uniformity and increased strength; which shall be operable by unskilled workers; which shall produce a given fabric with less materialywhich may be quickly made ready for the weaving operation and in which the woven fabric can be quickly and easily removed from the machine.

Other objects of my invention are to provide a weaving machine which can be constructed at a low expense and which can be maintained in working order with a minimum of attention and cost.

My invention consists generally in the form, construction, arrangement, and co-operation of the parts whereby the above named objects, together with others which will appear hereinafter, are attainable and my invention will be more readily understood by reference to the accompanying drawings which illustrate that form of my invention which I consider at the present time, the preferable form. In the said drawings,

That embodiment of my invention shown in the drawings is characterized by or comprises generally the following parts;

Frame,

Filler strand inserting means,

Filler strand packing mechanism,

Reed tensioning and pay out mechanism,

Driving mechanism.

As a matter of convenience, and in order to facilitate and simplify the description and understanding of the machine, I shall describe the parts'generally in the order above outlined.

The frame-The frame is characterized by a base portion 1; filler strand packing mechanism guide portion 2; and fabric limiting portion 3. The baseportion 1, corn prises a bottom portion i, upstanding portion 5, and horizontal portion 6. The portion 2, comprises spaced parallel plates 7 and 8 which are connected and rigidly spaced by a plurality of rods 9. Concentrically spaced around the lower plate 7, is a ring 10, which is supported from the upper plate 8 by means of a plurality of rods 11. The rods 9 and 11 are positioned on radial lines (best shown in Fig. 3) and are secured to the plates in a suitable manner, such for example as by nuts 12 and 13, which permit of convenient assembling and demounting oi the parts as will be more fully described with reference to the filler strand'pa'cking mechanism. The rods 9 and 11 and their fellows form guides for the sliding portions of the filler strand paclc ing means. In Fig. 2, only two diametrically opposite sets of rods 9 and 11 are shown, the other similar rods, which would be seen in this view, being omitted for the sake of clearness and simplicity. The fabric limiting portion of the frame is composed of a ring 15, mounted upon the plate 8, as by means of dowel pins 16 which properly position it and which permit its ready removal and replacement. Secured in the ring 15 and upstanding; therefrom are a plurality of members 17, as best shown in Figs. 2, 3, 6, 7, and 8. In Fig. 2, only two oppositely disposed members 17, are shown, the others be ing omitted for the sake of clearness. 1 might here state that one member 1?, is provided for every stake in the reed iiabric,the purpose and function of which will appear shortly. These members 17. are given that shape which is desired in the finished fabric and as will be seen, serve to limit the inward forming tendency of the fabric. The upper portions of the member 17, are secured in a plate 18, which construction rigidly holds various members in proper spaced relation.

Stake holding and positioning means. The stake holding and positioning means in this instance, is characterized by a circular band or belt 20, having a plurality of spaced holes 21, of a size to accommodate the stakes 22, snugly therein, that is to say, the holes 21, permit the placement of the stake ends therein and hold them frictionally to a sulficient extent to prevent undesired withdrawal or displacement. The band 20, in this instance is severed as at 23, and one portion has an extending eye 24, and the other portion spaced projecting eye portions 25, which. straddle the member 2 1, thus alignins; the eye portions and permitting; the placement of a pin26, to hold the band in closed position. The band may thus be readily opened by withdrawing: the pin 26. and if desired the stakes may be placed in the belt or band when it is straight and the band closed when the stakes are in position. The stakes may be somewhat more readily placed in the holes when the belt is opened and the curving of the belt serves slightly to pinch the respective stakes. The band with the stakes in position may thus be placed around the members 17, of the fabric limiting portion, placing the same on from above as will be readily understood from the en ailed description of the upper portion of the machine or if desired, the band may be wrapped around the member 17, and then fastened to make an endless band or ring. The band 20, abuts the ring 15, containing the member 17, and the stakes upstand therefrom following closely the general course of the members 17'. 1 might here state that I found great dilliculty in properly positioninn and aligning the stakes so that during "the weaving operation they would maintain desired regular spaced relation and would not become bent, lzinked, or otherwise injured or displaced by the weaving and packing mechanism. 1 finally solved this difficult problem in a simple and inexpensive manner. To this end, 1 form the members 11'. oil two pieces or relatively thin strap metal 30 and 31 which are suitably secured together against relative movement by any suitable means, such for example, as riveting; 1? (see Figs. 7 and 8). The members 30 and 31 are staggered thus forming inwardly and outwardly projecting portions num- 'ered respectively 32 and As will be seen, the inwardly projecting portion 3'2, forms a guide for the filler strand packing lii ;'er and the outwardly projecting portion 33, l orms'with the packing finger 35, of the filler strand packing means a space or groove in which the stake 22, is accommodated. The stake as is best shownv in Figs. 3, 6 and '7. substantially parallels the portion 33, of the member 31, and before the fabric is woven it lies throughout a considerable extent below the outer surface of the projecinn" portion 33, and as the filler strand is placed in position, the stake portions are successively spaced from the portion 33, the thickness of the filler strand. Having thus described generally the stake positioning and holding means and the i abriclimiting means, 1 sh new desedbe the means wh'ereby the filler trand placed over and under the sta ,es and will then follow with a detail description oi the means whereby the filler s nd properly packed or laid into position properly contiguous the preformed be 2-12mipuflclziinp' and GOILZ'TOZZ'i'IM] .Tb.e sta e manipulating and conling; means is characterized by a plate 40. .ilCll in this infiance, is of circular form and oi a size substantially co-e. il ensive witli the outer portions of the l'llOHlbBI 17., in one sense 'i'orani z; a continuation The plate ill. emorably mounted upon the plate 18, as l; means oi? dowel pins 1-1. Fir 52) so that when in position these parts V the edge of the plate rot-.e together. in

I term a curved groove 4:2, in which a portion of a helical spring 43, is accominodated. The spring 43, is of such a size with relation to the plate e0 as to tend to compress itself on the plate and into the groove 42, and is formed with two complete i-onvolutions for every stake ot the fabric. The spring is so positioned with respect to the stakes'that the stake can be moved into the contiguous \/-spa ces formed by OPPQ, sitely disposed portions of the spring as is best shown in Figs. 5, l, and 5. The stakes may move into this space a certaindistance but cannot get out of the spring entirely and the spring serves to carry the stakes in proper spaced relation during the interval in which the stakes are separated from the plate it) for the insertion ol the filler strands. The spring a3, is maintained against undesired shitting or circumteren 'tial creeping around the plate l() by means of studs or pins spaced substantially equidistant between the stakes. A portion 45 of every pin is beveled so that in the event of the spring striking the pin as it returns to position in the groove of the plate all) after passing around the tiller strand inserting means, it will be shifted back into position. The action 01" the pin in shitting the spring will be readily understood by reference to the detailed fragmentary sect-ional view .liig. 13, wherein the proper position of the coiled spring is indicated by means of dotted lines and the position .in which it sometimes strikes the pin indicated by means of full lines and as a cross section oi the spring. T he plate 40 is provided with verticle grooves -l7, for the accommodation of the stakes, these grooves permitting stakes to lie slightly below or flush with the outermost portion l8, of the plate l0. Thus the upper or free ends of the stakes are held in proper spaced relation and prevented trom getting out of their proper grooves. In the instant case, it is desired to provide a fabric in which the filler strand passes over one stake and under the next adjacent stake and to this end I provide means which moves out the upper portion of every other stake together with means for holding such projected stakes out for a period suliicient conveniently to insert the tiller strand at which time the stakes are permitted to return to their normal positions in the grooves of the plate 40 and in fact, are actually and positively returned to such positions. The means here shown for manipulating the stakes comprises a wheel having a plurality oi projecting somewhat teeth-like po"- tions 51. The wheel 50 is rot-atably mounted by means of stud 52, upon member 53, which is stationary relative to the plate 40. The plate so carries spaced studs or pins 54l, equal in number to the stakes of the fabric, and in this instance, radially aligned therewith and the Wheel 50 carries a gear memher 55, upon its underside with whichpins 5st, engage. Thus as the plate at) .lSlilllVQl'l in the direction of the arrows, by means toaway from the plate 10. The wheel 50,

arranged adjacent a somewhat lit-shaped stake spreader 56, the teeth 51, ot' the wheel 50 moving the stake, end portions out a distance beyond the outer side oil the point 5?, ol thespreader. Once the stake reaches this position it is caused to move still further away from the plate by erwagement with the outwardly extending spreader 56. At this point I arrange a relatively narrow and somewhat blade-like member (ill through the center of which is a tube (ll, through which theiiller strand (52, passes emanating from the lower end thereof around a very small curve projection 63, as is best shown in Fig. it. This blade-like member it will be seen is arranged very close to the outer portion oi? the plate a0 and has a curi d outer tace (i l, over which the stal-ze retaining coil l3, passes, the coil returning to its normal posh tion engaging the groove l2, and the pins so soon as the blade 6 1-, is passed. in this way it will be understood that the tiller strand til, laid in place to pass over one stake and under the next adjacent stake after which the ililler strand is properly packed upon the pretormed fabric by means to be shortly described in detail but before describing that mechanism 1 will point out some further details relative to the filler strand inserting means. i prefer to provide in addition to the stake spreader 56, another lower stake spreader which is constr cted similar to the spreader except that its point is somewhat closer to the plate (30 anddoes not project as far from the plate 60 as does the upper spreader, the object being to support the stake at spaced points to prevent undesired bending or likelihood of becoming entangled with the tiller strand inserting means. The arrangement and position of these Spreaders, is well shown in Figs. 4 and 6. There is a tendency for the stakes, l find, at times to spring out of their grooves and l have so far found it desirable to prevent any lilreihood oi? with the machine operating tically and rotatably. This is accomplished by providing a slot and bolt connection "(2, between the bracket Ti and its support and by splitting the end of the bracket 71 and there providaa bolt 1}, which can be tightened or loosened to permit raising or lowering of the plate and also to permit rotation of the plate it desired. It will also be undenitoml that the bracket 71 can be swung if necessary trom the bolt T2, as a pivot. in this manner, ample and accurate adjustment provider to the end that the exact distance between the wheel 50 and the stre spreader nay be provided which gives the best working action, although this may be varied to some extent Without destroying the co-operative rela tion of the parts. The position shown in the drawings will be found to be substantially correct. l might here add that in order to weave the fabric rapidly and yet to keep the speed of the parts within reason able limits, I lind it desirable, though not necessary, to insert a plurality of tiller strands at spaced intervals. In the instant case, it have shown the liller strand inserted at diametrically opposite points and with this construction, a given 'iabric can be compieted in half the time that would be required were single strand employed or the labric may be produced in the same time halt the speed. lVhen a single liller strand means is employed it is necessary that an odd nuniber of stakes be employed so that at each revolution the liller strand may pass over the stake which it passed under upon the previous revolution. 1n the instant case where two tiller strands are inserted, on even number ot stakes is employed to the same end. li hile before stated, it is de siraole to weave at a number ot points, I have touinl that this multiple weaving introduces new problems whith must be solved before a satisfactory :labric can be produced. These problen'is relate largely to the proper tensioning or the filler strand and to securing, Or rath r, placing curing eac i interval of time the same amount of liller strands at one point as is placed at the other feed point. The mechanism which iinally devised to this end will be described later under the head cl ldeed tensioning and pay out niedianism. While I am discussing the tiller strand inserting means and the contiguo'us mechanis l. I should add that I have so found it desirable to provide a spring member 80 attached to the stake spreader and which passes upon the inner side of the tiller strand inserting plate, the spring being imvardl resilient 5nd causingthe ends [2h remain in the grooves to be held inwarc to an extent sufiicient to avoid any interference thereof with the inner face oi the plate and then to prevent undue movement of the stakes under the action of the spring 80 (see Fig. 5) 1 pro vi-de an outwardly resilient spring member 81 which in this instance, is mounted upon the lwachet 'lhus a track or causenay a2, is provided between the spring 80 and ("5]. through which the alternate passive stakes pass. The machine shown is termed to produce a la ric of circular cross section, of diamaters differing from top to bottom and with a contour curved with respect to its axis, l. might add that such a l abrie can be used very extensively tor the 111M111 iacture o'i' many articles and when a fabric with curved contour is produced by hand in the hitherto universally customary man her it is a siow, laborious taslr and even then requires workmen who are highly skilled in the art. l have so far found it most 1-; ivenient to manipulate the stake ends nor the purpose inserting tiller strands when the stakes extend somewhat parallel to the axis of the machine, and l have, therefore, made the machine parts at the upper portion straight for a distance above the line to which the fabric is to be woven. l have also found that there is a teni euoy tor the stakes when approching and passing the weave point to spring away om their guides 30, oil the m mbers 17. lt is, of coi particularly desirable that the stakes shall be maintained in their proper spaced relation at this point and for the pui ose of returning the stakes to their proper positions at this point, should they become misplaced forward of their proper guide 17', I provide a wheel 90 mounted upon a list spring 9i which in turn is 'ltastened in a block 92, pivotally mounted in a bracket 93, which is fastened upon the upper portion of the blade 60, through which the filler strand passes. The bracket 93, is split and has bolt i'or clamping it upon the plate whereby it can be moved for the purpose of placing the wheel 90 in the exact position necessary to give the best results. I find this position to be substantially as shown in the drawings, that is to say, a little forward of the point where tie tiller strand is placed between the stakes so that as each stake approaches this point, it is pressed down into its groove by engagement with the wheel and as will be described shortly, the stake is prevented from being carried too much real-weirdly by means of the packing linger which at this time, adjacent the wheel and oppositely disposed therefrom. v

Filler strand packing mecham's mrlt is very important that the filler strand be properly and uniformly packed it the resulting fabric is to be of a character suit able for use upon high class articles. It will be understood that in this instance where the filler strand is "led between the stakes at the upper portions thereof, it is necessary to pack the filler strand from a point adjacent its entrance between the stakes to a point contiguous the pro-formed fabric. Obviously as the fabric is formed the extent of the packing varies. it is also necessary that the packing means be so constructed as not to interfere with the insertion of the filler strand. 1 have also found that extreme care must be used to prevent the packing means from catching upon the stakes throwing them out of alignment, crushing them and ultii'nately preventing the proper operation of the machine. After much experimentation I have produced the mechanism which I shall now describe and which, while extremely simple, serves admirably to pack the filler strand. Further more, not only does this mechanism'not dis align, injure, or crush the stakes, but it actually and positively realigns the stakes between each filler strand feeding period, should they for any reason become disaligned. The character of reed is such that it is likely because of inherent tendencies to assume irregular lines and furthern'iore, under the action of weaving, the filler strand thereon to be dragged from its proper spaced position. The filler st and pack; ing mechanism here shown is characterized by a weight 90 which is mounted for vertical sliding movement between adjacent pairs of rods 9 and 11 as by means of stud shafts 91 and 92, passing therethroii gh. The stud shaft 92 is provided with rollers 93 and 9 1, to reduce the friction incident to its sliding motion. in the lower end of the weight, 1 mount a roller 95, which in turn rests upon a cam 90. The cam 96, as best shown in Fig. 1, rises from the point 9?, to a ridge 98, which is of a width. Slllflttltl'lt to support a num ber of weights 90" thereon. It will be un derstood that the cam rises and falls upon each side of the machine (only one-half of the cam being viewed) the purpose beingto elevate the weight and to permit its proper descent during each half revolution of the machine, or in other words, to elevate the wei ht and to permit its descent. once for every filler strand. that is inserted. A stud shaft 91*, passing through the weight 90 is inwardly and outwardly extended to form end portions 97 and 98 the end portion 98 forming a handle whereby the weight can be manipulated by hand when desired, either to test the packer; to permit release of the fabric; or for such other purposes as may be necessary or desirable. The inner end 97, of the stud. 91 is slotted and the lower end of the upstanding packer arm 99, enters therebetween and is arranged for swinging movement therein by means of the pivot 100. I also prefer to form an elongated slot 101 in the lower end of the packer arm 99 through which the pin 100 passes, the arm 9.) being normally pressed upwardly by means of a spring 102 which normally maintains the pivot 100 in the lower portion of the elongated slot 101, the purpose of which will be shortly described. Upon the upper end of the rod 99, I mount a finger 103. The linger 103 has a nose portion 104; which is normally projected through the spaces between the fabric limiting members 1?, as is well shown in Fig. 3, by full lines, and by dotted lines 2 and 6. The normally extended position of the packing finger is also illustrated in Fig. 7. The packing arm is continiiiously pulled radially outwardly of the machine by means of a tension sprinp 105, which is attached to and extends between the packer arm and one of the weight studs, in this instance, the stud 91 and the outward movement of the finger is limited by means of a collar 106, upon the packing finger 103,. which engages the inwardly projecting portion 82, of the member 17. as is probably best shown in Fig. 8. This construction not only limits the out "ard .movement of the finger but also forms a guide directing its to and fro move ment in the path in which the fabric is to be formed, which in this instance corresponds to the contour of the member 17. 1 might here add that this yielding construction of the packer arms permits it readily to follow guides of different forms as may be necesy for the construction of differently shaped fabrics. The cam 96, which raises the weights is frameportions 2 and 3, which are given rotation by means described under the heading Driving; mechanism.

The cam 96 held against rotation by means of upstanding rods 120 which are passed through the portion 6, of the frame base and these rods may be vertically adjusted to vary the height of the cam 96 by means of the nuts 121 and 122 engaging the upper and lower surfaces of the base portion 6. Thus as the parts 2 and 3 of the machine are rotated and the cam remains stationary the weights are caused to ride up the inclined portion of the cam thereby elevating the packer arm which follows the guides 17. until the rollers 123, upon the upper inner ends thereof engage the frame plate '18, at which time further continued rising of the weight causes the arm to swing in wardly the inward movement continuing "until the annular stop 124;, is reached at which time the weight 90. has also reached the hinfl'iest portio': 93, of the cam which it will be seen is shahtly before the point where the tiller strand is inserted. The veinht rides upon the ridge 98, for a period suficient to hold the finger in retracted position until it has passed the filler strand at which time the weight is permitted to destationary with respect to the scend and so soon as it starts its downward course the packer arm under the influence of the tension spring 105 is immediately drawn radially outward into position between the spaced members 17. It will be understood that the packing finger is now upon the upper side of the filler strand and as it descends hangs upon the filler strand, the weights 90 being sufficient properly to pack the filler strand into position adjacent the previously laid filler strands of the fabric. Of course, for the first partial revolution the packer arm descends to the dotted position indicated in Fig. 1 or in other words to the band 20 in which the stakes are mounted but as the filler strands are inserted and the fabric is formed, the weights descend a lesser distance each half revolution. 1 might here add that accurate adjustment of the packers is unnecessary because the weights simply fall by gravity until the nose 104 of the packing finger engages the preformed fabric at which time the weights hang from the fabric until the upward incline of the cam is again reached at which time they are elevated, retracted, held in retracted position for an interval to permit insertion of the filler strand and then reprojected above the filler strand to again descend and cause the proper packing thereon. Again extremely accurate placement of the cam 96, is eliminated by the slotted construction 101 of the lower end of the packing arm 99, which permits taking up of con siderable excess motion of the weight 90*. the compression of the spring 102 being of suflicient strength to cause the packer arm to move in against the tension of the spring 105.

As before stated the stakes may at times become disaligned or spring away from their proper position paralleling themembers 17, as for example, the stake may spring into the space between the adjacent members 17 as indicated by the dotted lines in 7. and unless some means were provided. for re-aligning the stakes they would become pinched or wedged between the finger and the member 17, or otherwise becoming entangled thereby stopping the operation of the machine and preventing the formation of a proper fabric. After experimenting with various means to obviate this objection I discovered that by mounting a round projection 131 upon the packer arm 99. which is below the packing finger 103, that as the packer arm is raised and lowered the stake if dis-aligned is replaced to its proper position. This projection 131. in its outermost extent 132, is substantially co-incident with the outer-most portion 30 of the portion 30 i of the fabric limiting the elements 1.7. I

find that with this device the machine can be operated at relatively high speed; that the packer arms While thus moving rapidly back and forth in the grooves will re-align with marvellous dexterity any stakes that have become displaced from their proper proper alignment with the member 17, and that in the finished fabric the stakes are remarkably straight so much so that the fabric is far superior to the fabric which is producible by the most skilled workers under the hitherto customar 1 hand weaving methods. Thus it will be seen that the stakes are properly aligned and that they are prevented from getting away from the member 17, in the other direction because of the projection 33, against which they normally lie prior to weaving of the filler strand. As before stated in case they should for any reason get out of alignment in that direction they are replaced by the wheel 90. which is prior to the feed, this wheel tending to shove them in the other direction and being prevented from shoving them to an extent too great by means of the projecting nose 104 of the packing finger which at that time is adjacent to this wheel as will be understood by reference to Figs. 1 and 4.

Reed te'naz'om'ng and dispensing mecham's'm.-As before stated it is very important that the tension of the filler strand be maintained constantly to just the right extent, if the fabric is to be uniform in ap pearance and strength especially is this so where two or more strands are woven simultaneously. I have devised a novel mechanism whereby the filler strand tension can be maintained uniformly throughout the entire extent of the fabric and irrespective of the amount of reed which may be upon the reel. Where a multiple feed is employed such as shown in the instant case not only is it desirable that the tension be uniformly maintained upon each filler strand but it is also desirable that the amount of the material inserted at the two feed points during a given period of rotation be practically the same or there will be a. noticeable looseness in one of the filler strands as compared with the adjacent filler strand. The structure which I have designed to this end comprises a wheel having two beveled or angling faces 140 and 141 which are bounded by flanges 142. 143, and 144. The wheel is mounted upon a stud shaft 145 suitably mounted in a bracket 146, and the bracket 146, has 2 depending portion 147, to which is secured filler strand guide 148. having separate parts 149 and 150 through which the filler strands pass. Asis well shown in Fig. 9. this guide is crimped as indicated at 151 so that when the reed is pulled therethrough it does not pass freely but is retarded to an extent necessary to cause it to be taut between he guide and the tensioning wheels. The filler strands are mounted upon separate spools or reels 160 and 161 which are rotatably reels and in passingover the wheels i tll and 14-1 is put under tension. lluch particle. of reed must pass rnibstantiall twice around the tension wheel which is of constant 'diameter and hence the tension on the reed is uniform whether there be muohor little reed upon the spool'or reel. Theftaces l d and 141 being; of identical size and mo together necessarily pay out accurately.

measured quantities of filler strands to each feed point. In order to adjust the tension upon the reed. I provide a threaded rod 165 extending from the stud 145 of the tension wheels and upon this threaded red I mount a thumb nut 1'66 lifl-VIDQ' a flange 16?. Abutting the flange of the sion wheel I place a friction disc 168 p1," erably composed of fibre and this disc is pressed against the flange of the thumb nut. and the friction disc as is well shown in Fig. 10. By this means the tension of the filler strand may be very accurately regulated and the filler strand put under inst that degree of tension which res the best results for the particular filler strand employed. The exact tension necessary will. depend somewhat upon the character and size of the tiller strand; the size and character of the stakes employed: the size and number of the packing; weights as well as other features. i [Wining 'mcc/i(m iam.7llhe machine. in. this instance, is driven from the drive shaft 110. upon which are mounted. loose and fixed iulle vs ill and 1112, over which the driving belt 113 operates. through the meshing bevel gears 115 and 116; the vertical shaft 117 carrying; the pinion 118 which in turn meshes with the 119 bolted 'to'lbe lower plate 7. of the machine frame. in this manner it will be understood that the frame and parts carried thereby are can, d to rotate while the vertical central shaft 110 remains statioimr and forms rirgid support for the rotating machine. The

shaft in this instance is firmly fired against rotation by means o't pins 120 which through the shaft and the long hub like portion 121 of the base.

ltlavine thus described in detail the various structural features and their eo-operm tive relation I shall briefly state the operation of producing a completely woven fabric thereon. To "this end let us assume that the band 20 has been removed from the mastrand is chine. Stakes of the proper length are then being substantially flush with the lower endl of the band. The hand containing the proper number of stakes then placed upon the machine. This may be done either by wrapping the band around the machine and then ti' astening the abutting ends, oriirst fastening the belt or band to form a ring as shown in Fig. ii and then placing same over the top of the II'HtCllillQ. To enable placei'nent of the band over the top of the machine and to permit removal of the finished faltiric, the plate ll) and all mechanism carried thereby can belmdil} lifted from the rest of the machine to facilitate which operation 1 preferably provide eyes 170 in the upstanding portion 17L. of the plate 130 {see 1 1g". 2). The plate 130 is lined against rotation by means of set screws "32 which enter a groove 133, in the upper end of the shaft 110. When the part 130 is lifted the plate so and mechanism carried thereby is be drawn to position when replaced. In

placing;- the stain: band upon the machine, care n'uist be ttlitili to see that the stakes are positioned substantially in front of the por tion 30 of the guides 1.7. The stal-Ies are maintained. in the band so that whenthe band engages the members 17, the stakes will be held a sufficient dis. nce away from the outer surface of the member 17. to permit the insertion of tl'iefiller strandftherebetweenv After the band and stakes are placed. in positionthe head plate 40 and its asociated mechanism lowered into place being); ac urately ejuidcil into proper position by means of dowel pins ll (see Fig 2-). The free ends o t the stakes are then passed under the retaining coil ii). each stake entering: its proper groove 4-7. in the plate 34 Theiiler strands may he then threaded over in; under the stakes from the point of: entrance to the bolt along the general curved line defined by the various packing; fingers or i find that the machine can be started without three the tiller strand over and under these st s by Sll pulling from the reel. a su'liicient len th of fillerstrand as when the nachine is started the tiller aut'oniaticall laid into position and rarrn by the packers jironi the entrance posi 'oni'lown to the belt.

It will now be understood that practically all of the lingers of 1 e paclmrsrest upon the complete fabric and in order to release the l mric it is necessary to move the lingers inwardly. This can be done readily by simply pressing the fingers by hand inwardly and lowering the weight to a position resting upon the cam. When all of the fingers are thus released. the fabric can be bodily raised and removed from the machine; the band pulled from the stakes; new stakes inserted; the stakes and band replaced upon the machine; the weaving plate lowered and the machine is again ready for weaving the next fabric. 1 neglected to state that when releasing the fabric from the machine the auxiliary stake retainino spring is first stretched up over the stake retaining spring 43, and over the top of the stakes so that when the plate 40 is raised there is nothing to catch upon the prevent free release of the weaving parts. There are many other ways in which the machine can be made ready for the weaving operation, all of which will readily suggest themselves from this detailed disclosure to thosewho are skilled in the art. l or example, instead of preparing the machine in the manner stated the stake retaining band may be placed upon the machine and then the stakes inserted in the stake holes instead of first placing the stakes in the band when it is in dependent of the rest of the machine.

lVhile before suggested wish to add more definitely that fabric of different shapes, within certain limits, can be readily woven upon a machine embodying my invention. This is readily accomplished by lifting the head plate and associated mechanism from the fabric limiting portion 3 and then lifting the fabric limiting portion 3 from the part 2, placing a fabric limiting portion of desired shape on part 2 and replacing the head plate and associated mech anism. The removable dowelled construction enables quick and easy repositioning of the parts. Inasmuch as this complete disclosure will readily suggest to others modified structures whereby the substantial objects and advan of my invention may be attained I do not wish to be limited to the specific construction herein shown and described except only as may be necessary by limitations in the. hereunto appended claims.
